    15 20 25 30 35 coverage. Tools for adapting and installing metal covering systems are e.g. drills and / or screwdrivers, metal cutting saws (since support brackets and cover panels in accordance with the state of the art are often made of relatively thick metal), nibbling machines, sheet metal shears and motorized cutting machines. The drilling machines can be used to make holes, but are normally also used as screwdrivers when mounting the support structure and cover panels to screw the support structure against affected surfaces, such as walls, ceilings and floors, and to screw the panels into the support structure. It is therefore necessary to frequently change from drill to screw bits and back again, or to have two different drills. Hand-held metal cutting saws or cutting machines are used to cut the related parts by free-hand sawing, supported by pen markings if necessary.
    A disadvantage of the known systems and methods for covering duct systems is that they require a great deal of work, since several people carry out their work successively one after the other. This means that a subsequent craftsman cannot perform his part until the previous craftsman has finished his work. Another disadvantage is that many different tools have to be used and transported around. Motor tools are also often bulky and heavy, and are therefore not easy to carry around in a workplace. This makes it difficult to install the cover systems quickly and efficiently with a minimal amount of work, especially when using heavy motor tools and when several craftsmen with different skills and job descriptions need to be monitored and coordinated. Another disadvantage is that the heavy-duty craftsman must perform countless cuts each time such a cover system is installed, with the risk of overexertion. Furthermore, it is necessary to remove the burrs from the ends of the panels and brackets when these are cut with metal chainsaws or other motorized cutting machines.
    Therefore, special systems for enclosing or covering ducts, pipes and drums, e.g. ventilation duct system, developed. An example of such a specialized sheet metal containment system is described in EP 0 420 308 A1. This enclosure uses a support profile for continuous mounting along a wall as well as support brackets which extend transversely therefrom for fastening external containment parts substantially parallel to the support profile.
    It still takes a lot of labor with different skills to install the different parts that make up the containment system. According to the state of the art, a large number of different and separate fastening devices are used, such as screws, bolts and nuts, welding and separate clamps to fasten the containment systems to walls, floors and ceilings and to fasten the individual components of the containment systems, such as support profiles, support brackets , support and clamping plates, separate containment parts, e.g. front panels and grille parts, etc., to each other. Furthermore, a motor-driven cutting tool or several different tools, such as angle grinders and metal cutting saws, are needed to cut the desired lengths of the parts that need to be cut, e.g. support profile and containment parts. Furthermore, angle grinders are in many cases not a particularly attractive alternative for cutting, especially for cutting ducts for ventilation systems. This applies above all to work indoors, which is often the case when installing ventilation duct systems. Angle grinders are very noisy, which increases the risk of hearing damage and makes it necessary to wear hearing protection. Cutting with an angle grinder also causes sparks, which poses a fire risk. Furthermore, any abrasive residues can accumulate and stick to surfaces exposed to moisture, such as in bathrooms and kitchens, with the risk of them starting to corrode and discolour the surfaces. Abrasive residues can also damage the eyes.
    In addition, due to the mode of operation, angle grinders and metal cutting saws can cause burrs on the inside of the cut part. The cut parts must therefore be deburred before they are connected to each other, e.g. using a file or knife for deburring, which increases the number of tools and the related weight that needs to be transported around. Otherwise, the burrs can damage sealing rings, the fitter's hands and the like. Unfortunately, there are no known systems for enclosing or covering ducts, pipes and drums, e.g. ventilation duct systems, especially flexible when it comes to choosing cutting tools.
    Summary of the invention An object of the invention is to provide a system and a method for installation, mounting and covering of ventilation ducts which solve or at least reduce the above-mentioned problems.
    An object of the invention is to enable simple installation, installation and covering of ventilation ducts by making it possible for only one person to both install and cover the ventilation ducts, e.g. the ventilation fitter.
    Another object of the invention is to enable installation, fastening and covering of ventilation ducts which offer both an ergonomically correct working method and an ergonomically correct working position.
    Yet another object of the invention is to enable installation, fastening and covering of ventilation ducts with fewer number of tools and thus lower related weight when the tools are carried around and handled by the fitter. Yet another object of the invention is to enable the installation, fastening and covering of ventilation ducts in a manner which makes it possible to cut the related parts constituting the containment system without causing degree formation on the inside of the cut parts and without causing excessive noise or hazardous sparks.
    These objects are achieved by means of a system and a support bracket for installation, mounting and covering of ventilation ducts according to the related independent claims, with preferred variants defined in the related subclaims.
    These objects are further achieved by means of a method for installation, mounting and covering of ventilation ducts according to the independent method requirement, with preferred variants of the method defined in the related subclaims.
    The system for mounting and covering ventilation ducts in accordance with the independent system requirement makes it possible to simplify and ensure a correct placement and installation of the system's related parts of a person, as fewer measurements and test assemblies need to be made.
    The above systems for mounting and enclosing ventilation ducts and support brackets for wall and / or ceiling mounting comprise at least one support bracket, where the support bracket is arranged to be attached to walls and / or ceilings and to the ventilation ducts, and further comprises control devices arranged on the support bracket, where the support bracket is arranged to cooperate with the ventilation ducts and the control devices to provide a predetermined relationship between the control devices and the ventilation ducts, wherein said support bracket is arranged at predetermined points to regulate the location of the control devices and ventilation ducts by controlling the control devices and ventilation ducts. place relative to each other during assembly. In one embodiment, the system comprises at least two control devices arranged on each support bracket. In some embodiments, the control devices are integrated in the support brackets or removably attached to the support brackets by means of spring clamp brackets. The number of integrated or removably attached control devices makes it possible to ensure that the related parts of the system can easily be positioned relative to each other in a distinct and safe manner while at the same time a simple assembly and disassembly of the system is possible. In some embodiments, the guide devices are removably attached with at least one retaining shape, and / or the guide devices comprise rails arranged to be releasably mounted on the support bracket by means of the retaining mold, and / or the guide rails are arranged to be releasably fitted in the retaining shape in the form of at least one recess at predetermined points on the support bracket, where each recess has a varying shape, and / or the recess comprises an opening for the support rail which is wider than the bottom of the recess.
    In other embodiments, the system comprises at least one panel arranged to be removably attached to the control device and to cover the ventilation ducts and the support brackets after mounting, and / or the control devices are arranged relative to each other so that the support bracket and the ventilation duct are located at the predetermined points for controlling the location of the cover panel relative to the support brackets and ventilation ducts, where the support bracket and ventilation duct allow all parts of the ventilation ducts to be placed towards the front of a cover panel at a distance from the control devices and any edge of the cover panel after installation. In some embodiments, the components of the ventilation ducts may consist of fan grilles, sockets and / or air outlet inlets, and / or each panel is attached to the control devices by means of spring clamp brackets, and / or the control devices are at least partly designed as spring clamps, and / or designed as spring clips along at least parts of their length or along their entire length.
    In some embodiments, the support bracket is adapted to hold the ventilation ducts detachably in place by means of at least one flap which can be folded into and out of engagement with the ventilation ducts by means of a perforation, or the flap is arranged to extend over at least a part of the ventilation ducts. the circumference of the ducts in the unfolded state, so that it is possible for the support bracket to hold the ventilation ducts in place, and to expose the ventilation ducts in the folded state, so that it is possible to detach the ventilation ducts from the support bracket. In one embodiment, at least one guide plate is arranged to be placed inside the guide devices at a joint between the guide devices. The support and containment system in accordance with the invention comprises support brackets, control devices and, optionally, cover panel. The panel is not included when no covering of the ventilation ducts is required.
    The support bracket according to the invention is intended for fastening the ventilation ducts and for mounting against walls and / or ceilings, where the support bracket is arranged to be attached to walls and / or ceilings and to the ventilation ducts, and comprises control devices, and is arranged to cooperate with the ventilation ducts. and the control means for providing a predetermined relationship between the control devices and the ventilation ducts, which support bracket is arranged at predetermined points for controlling the location of the control devices and the ventilation ducts by guiding the control devices and the ventilation ducts in place relative to each other during assembly, and enabling simplify and ensure the correct placement and assembly of the system's parts of a person, as fewer measurements and test assemblies need to be made.
    In some embodiments the support bracket is arranged to cooperate with at least two guide devices, in other embodiments the guide devices are integrated in the support brackets or arranged to be removably attached to the support bracket or the support bracket is arranged to removably hold the guide devices in place by at least one retaining shape.
    The effect of the invention is that any fan grilles, sockets and / or air intakes / outlets end up at the desired location, e.g. at the level of adjacent ventilation ducts and / or on the front of a cover panel, and does not end up too close to ceilings, floors, walls, control devices or even impacts in the control devices and / or any edge and / or corner joint on the cover panel.
    Consequently, the distance from the control devices and the corner joint of the cover panel, the walls, the ceiling and / or the floor to the fan grille, sockets and / or air intakes / outlets is regulated by the innovative support bracket by means of the control devices by predetermining the cover panels.
    The system support brackets, control devices and cover panels in accordance with the invention are made of sheet metal with a thickness suitable for manual cutting using one and the same non-motorized cutting tool. It eliminates the need for more than one cutting tool when installing the support and containment system and reduces the workload for the craftsman who installs the system. The cutting tool for cutting the above parts of the innovative system is preferably a scissor tool. The fact that a scissor tool is used makes it possible to avoid degree formation on control devices and cover panels. Furthermore, a scissor tool does not cause dangerous sparks.
    The scissor tool is preferably a sheet metal scissors. This is a highly efficient cutting tool that does not cause sparks or excessive noise.
    In one embodiment, all joints between adjacent panels in assembled condition are covered by at least one bar strip that is removably attached to the panels by means of fi spring clamps. In other embodiments, the bar strips are made of sheet metal with a thickness suitable for manual cutting using one and the same non-motorized cutting tool or made of plastic.
    Each bar strip can be removably attached to the panels by means of at least one flap which can be folded between a first position which holds the bar strip in place over the joint by engaging the panels and a second position which enables removal of the bar strip from the joint by detaching it from the panels. Each bar strip can also be made of magnetic metal sheet and be removably attached to the panels by means of at least one magnet.
    In some embodiments, in addition, the control devices made of sheet metal, the cover panels and the moldings reduce the weight of the parts that make up the system. It reduces the craftsman's workload when cutting the control devices, cover panels and bar strips, as well as during general handling, assembly and lifting of these parts.
    Bar strips made of sheet metal with a thickness suitable for manual cutting enable easy adjustment of the strips by cutting / cutting at least one foldable flap in the bar strips to achieve easy attachment of each bar to the panels.
    In accordance with the invention, a method of installing a system that supports and encloses at least one ventilation duct and at least one support bracket for mounting against walls and / or ceilings, that the support bracket is attached to walls and / or ceilings and to the ventilation ducts. The method further comprises attaching the support bracket to walls and / or ceilings in a first position, placing control devices towards the support bracket, attaching the support bracket to walls and / or ceilings in a second position, placing the ventilation duct in the support bracket, and arranging the support bracket so that the ventilation duct and the control devices have a predetermined relationship at predetermined points for regulating the position of the control devices and the ventilation ducts by guiding / aligning the control devices and the ventilation ducts in place relative to each other when the system is mounted. One embodiment of the method comprises mounting the system by attaching the support bracket to walls and / or ceilings in suitable positions by screwing the support bracket to the actual surface in the first position, after which the screws are tightened to place the support brackets in the second position. Another embodiment of the method comprises that the control devices are pressed against the wall and / or the ceiling of the support bracket when the screws are tightened.
    Yet another embodiment of the method comprises folding a flap to a first position to arrange the support bracket in a receiving or releasing position for a ventilation duct, and after placing the ventilation duct in the support bracket, folding the flap to a second position for arrange the support bracket in a retaining position for a ventilation duct and vice versa.
    The innovative system, the support console and the method for attaching and covering ventilation ducts also make it possible to very easily adapt the different parts of the system and thus the system itself to ventilation ducts with different dimensions, different installation locations as all locations may differ in configuration, and different sizes of the installations. The system, support bracket and method according to the invention can be used to cover and enclose other types of ducts in addition to ventilation ducts or even in combination with ventilation ducts, e.g. water pipes, electrical cables or even cable ducts with small dimensions inside the containment system, as well as ducts for industrial or central vacuum cleaners.
    The innovative system, the support bracket and the method for attaching and covering ventilation ducts also enable easier maneuvering of the scissor tool and the part to be cut when cutting. This reduces the workload and work effort of the craftsman who installs the system as the number of steps required to perform the task decreases as no or very little deburring needs to be performed and only one cutting tool needs to be used.
    Furthermore, the innovative system, the support bracket and the method for fastening and covering ventilation ducts create an adaptable or self-adjusting configuration by predetermining the relative location of the cooperating support bracket and control devices, and in some embodiments also the system cover panels, relative to each other during assembly. This reduces the need to measure and hold together the support brackets and control devices, as well as in some designs also the cover panels, during assembly. For certain steps or assembly steps 10 15 20 25 30 35, the manual adjustment of the relative positioning of the support brackets and the control devices, as well as in some embodiments also the cover panels, which together form the system, is eliminated. In other embodiments, the control devices and cover panels in particular are very easy to dismantle for quick access to the ventilation ducts and other equipment, such as air inlets / outlets and electrical outlets.
    In some embodiments, only the support brackets, which are used for mounting and covering the ventilation ducts, need to be fixed to walls, ceilings and / or floors with separate fastening devices, such as screws, while the system control devices, cover panels and bar strips are installed using integrated fastening devices, e.g. ex. by being part of the support brackets or by means of spring clamp brackets, in order to make the system easy to transport and stow away by reducing the number of parts, fastening devices and components required for installation of the entire system.
    The support brackets, control devices, cover panels and bar strips are preferably made of thin metal sheet. These parts are thus easy to install, move around a workplace, stow away and transport thanks to lower weight per unit length.
    In an embodiment of the innovative method for installing the system, a scissor tool is used as a tool for cutting. The method for installing the system in accordance with the invention enables the use of the control devices in the form of rails configured so that the rails can be cut manually to the desired length by means of a sheet metal scissors when they are to be mounted. In another embodiment of the method, the guide rails are cut manually with the aid of sheet metal scissors and then bent manually until they come off to the desired length during assembly. In yet another embodiment of the method, the panels are configured so that they can be cut to the desired length and / or shape by means of a nibbling tool during assembly.
    In summary, the system, support bracket and method of the invention for mounting and covering ventilation ducts reduces the number of craftsmen required for installation, and also reduces the number of working hours required for installation by simplifying the work and reducing the work effort to handle and install the system and its components. . Furthermore, the support brackets, control devices, cover panels and bar strips are easy to prefabricate and are then easily adapted on site in length, shape and / or dimension to the special requirements that apply at that location.

    Detailed Description of the Invention The system 10 for mounting and covering ventilation pipes or ducts 20 shown in Figs. 1-17 is specifically designed for easy installation and covering of the ventilation ducts, in particular spirally wound ventilation ducts with rebate joints. The support and containment system 10 has a load-bearing structure in the form of support brackets 30 for detachable attachment to the floor, ceiling 10 15 20 25 30 35 11 11 and / or walls and control devices 50 for detachable attachment of at least one cover panel 40 which at least partially encloses parts of the system in assembled condition. In some aspects, e.g. if the system 10 is to be installed in industrial environments, no cover panels are needed as there are no corresponding aesthetic requirements in industrial environments, ie. the system does not have to make the ventilation ducts 20 "invisible" in industrial environments.
    On the support structure 30, 50, at least one panel or several panels 40 and at least one bar strip 60 are mounted, which bar strip is used as a cover piece to cover any joints between the cover panels if several cover panels are mounted, to cover the control devices 50, support brackets 30 and ventilation ducts 20 after mounting. A support bracket 30 is shown in Figs. 1-3, 7, 13 and 14, with a shape similar to a claw or a grip and a fixed design as well as dimensions that can be adapted for each type and dimension of the ventilation duct 20, depending on the duct dimension. The function of the support bracket is to releasably grip or hold the ventilation ducts so that they can be easily inserted into and removed from the support brackets 30 during assembly and disassembly of the ventilation ducts, respectively.
    Alternatively, the support bracket 30 can be adapted for attaching other types of ducts or pipes instead of ventilation ducts 20 or in combination with ventilation ducts, e.g. water pipes, cable ducts with small dimensions that fit inside the covering cover panels 40, electrical cables and / or ducts for industrial or central vacuum systems. Several ventilation ducts can be attached and enclosed in parallel with each other.
    The system 10 is mounted by securing the support bracket 30 in a first position to the wall, ceiling and / or floor in suitable positions by screwing the bracket loosely to the actual surface with screws inserted through the mounting holes 36 in the support bracket and the mounting holes in the wall, ceiling and / or the floor after the necessary openings for air intake have been taken up and other necessary measures have been taken. The procedure for taking up inlet holes in the building prior to installation of the mounting and covering system 10 is not explained in more detail because the uptake of these air intake holes is done in a known manner.
    In one aspect of the invention, the guides 50 are integrated in the support bracket 30, which means that the next step in the installation of the mounting and cover system 10 is to tighten the screws in the mounting holes 36. In another aspect of the invention, the guides 50 are separate components, which means that the next step in the installation of the mounting and cover system 10 is to insert the control devices, e.g. in the form of separate loose rails 50, removably in the support brackets 30, and then tightening the screws in the mounting holes 36 to arrange the support bracket in a second position.
    In this aspect, the guide rails 50 can be pressed tightly / firmly against the wall, ceiling and / or floor with a foot-like part 30a, 30b on the support bracket 30 when the screws are tightened (see Figs. 1 and 7). In Fig. 7, the foot-like parts 30a, 30b are formed by folding the support bracket along a fold line (see arrows in Fig. 7) so that the part with the mounting hole 36 forms the foot-like part running in a plane perpendicular to the plane of the support bracket after folding, i.e. the foot-like parts run in the normal direction towards the extended plane of the support bracket. Once the bracket has been mounted by placing its foot-like parts 30a, 30b against the wall, floor and / or ceiling, and securing the support bracket to the actual surface by screwing, the ventilation ducts 20 are mounted by being placed in the support bracket 30 and then secured therein. explained in more detail below).
    Thereafter, at least one cover panel 40 is removably attached to the guide devices 50 by being pressed into or over predetermined points on the guide devices in that the guide devices act as capercaillie clamps 51 (this is also explained structurally in more detail below).
    Finally, at least one bar strip 60 is removably attached to the panels 40 over the joint between two panels, i.e. when more than one panel 40 is used, to cover the joint thus formed, e.g. with spring clamps 61 in a corresponding manner as the panels themselves are attached to the guide devices 50. This bar strip can also be used to cover any joints between panels in corners, ie. corner panels for both outer and inner corners (not shown). These outer and inner corner panels may be removably attached to other panels 40 by means of similar spring clip brackets as the cover panels 40.
    Each of the support brackets 30 has a base part with the foot-like parts 30a, 30b and the fastening holes 36 for fixing the bracket to the wall, ceiling and / or floor by means of screws or similar fastening devices. The holes 36 may be elongate or oval to allow some adjustment of the bracket 30 before the screws are finally tightened to allow tolerance for defective installation, skewed surfaces or oblique mounting.
    Each support bracket has a channel receiving opening or recess 37 arranged to be at least partially enclosed or exposed by foldable parts 31 or details similar to foldable flaps, as shown in Figs. 1, 3, 7 and 13.
    The channel receiving recess 37 on each support bracket 30 is arranged to enclose at least 180 ° of the circumference of the channel 20 when it is held by the bracket and to enclose about or less than 180 ° of the circumference of the channel when it is moved. into or removed from the console. This varying width or opening of the channel receiving recess 37 is achieved in that the flaps 31 are manually foldable from and towards each other along a folding line formed by perforations 32 to achieve a similar function for the flaps 31, i.e. similar arms that can be brought in and out of engagement with the channel. In most cases, the flaps 31 can be folded at least 90 °, ie. the flaps can be folded between a position where the flaps extend in a substantially perpendicular direction or radially relative to the longitudinal direction of the channel 20 and another position where the flaps extend in a direction which is substantially parallel to the longitudinal direction of the channel.
    Each of the foldable tabs 31 forming part of the channel receiving recess 37 is foldably attached to the bracket 30 at a base portion where a hinge function is provided through the perforations 32 along the respective fold line. Each of the foldable flaps 31 also has a free end with a further foldable part 38 which can also be folded along other perforations 32 '(see Fig. 7). This second foldable flap 38 is provided with a hole 39 in the free end to enable attachment of the duct 20 by means of a screw for screwing the flap against the ventilation duct when the duct is placed in the bracket.
    This second foldable flap 38 can be folded towards the channel in a first position, and in some cases in contact with the channel, so that the second foldable flap 38 is substantially parallel to the longitudinal direction of the channel. The second foldable tab 38 can also be folded away from the channel to a second position, and it also follows the movement of the first foldable tab 31, at least in part since this second foldable tab is part of the end of the first foldable tab 31.
    This second foldable tab 38 is also part of the support bracket 30 in FIG. 13 in the same way as in fig. 7.
    Furthermore, the support brackets 30 may be made of sheet metal, e.g. by cutting or punching the brackets out of sheet metal with a shape similar to an L seen from the side. The channel receiving recess or opening 37 is arranged between the legs of this L. The channel receiving recess 37 is located in the plane of the support bracket, said plane having a normal vector substantially parallel to the longitudinal direction of the channel 20 when the channel is placed in the bracket. The channel receiving recess has a contact surface for the channel, the contact surface having at least one contact point against the channel along a curve, contour line or contour edge which forms part of a semicircle with radius R which can be adapted for channels of different dimensions, wherein different brackets 30 are used for different channel dimensions since the dimension of each bracket can be varied according to the radius R (see Fig. 7). The contact surface is formed by both an inner, non-movable contour line and an outer, movable contour line in the form of the foldable flap parts 31, 38, i.e. the boundary or boundary line between the fixed inner contact surface and the outer movable tab portions 31, 38 is formed by the fold line of the first foldable tab 31. The fold line of the first foldable tabs 31 is the dashed line which also defines the base portion of these tabs 31 along the perforations 32 closest to the support bracket. as shown in Figs. 1, 7 and 13.
    Each carrying bracket 30, shown in fig. 1, 7, 13 and 14, the connecting corner between the legs of the L has beveled, but could of course also have a right-angled or curved corner. The beveled shape is used to make it possible to install the support brackets 30 against corners that are not completely straight and / or right-angled, and if there are any. irregularities or electrical cables in the corner, ie. the support brackets have been given this shape to achieve a clearance in their corner area.
    The attachment and cover system 10 includes support or guide devices 50 located at the support brackets 30. These guide devices are arranged against the support brackets so that the brackets cooperate with the ventilation channels 20 and the control devices to achieve a predetermined relationship, orientation or relative position between the control devices and the channels. after mounting. This predetermined relationship is achieved because the support brackets are arranged at predetermined points for regulating the positioning of the control devices and the ventilation ducts by guiding the control devices and the ventilation ducts in place relative to each other during assembly. This predetermined relationship is also achieved by the control devices being arranged at predetermined points on the brackets. This arrangement eliminates the need for additional control devices and / or reduces the craftsman's manual measurements during installation of the system which includes the support brackets and control devices. The assembly of the components that make up the ventilation system's mounting and covering system 10 is therefore done in a predetermined manner that is tolerant / forgiving of incorrect installation and oblique assembly, especially in old buildings, where walls, ceilings and floors are most likely skewed.
    This arrangement and system 10 provides in principle an almost "automatic" adjustment which causes the various parts of the system to "fall into place" during assembly, since the support brackets 30, by being arranged at predetermined points, control the placement of the control devices 50 and the ventilation ducts 20 by controlling the control devices and the ventilation ducts in place relative to each other during assembly.
    The guide devices 50 may be integrated in the support brackets 30 or be releasably attached to the support brackets by fitting into a retaining mold 33, 34, 35, i.e. at least one recess 33, and in most cases pressed by the foot-like part 30a, 30b on the support brackets against the surface with which they are in contact (see Fig. 7), e.g. the wall and / or ceiling. This mating is achieved by removably fitting the guide devices in the locating or guide recess 33 at predetermined points on the support brackets 30. Each guide recess 33 has a varying shape so that the guide device is guided into the recess and held in place by it. This provides a controllable and error-correcting function that simplifies alignment / level adjustment and positioning of control devices and support brackets on site and relative to each other. Each of the positioning recesses 33 has a guide receiving opening 34 which is wider than the bottom 35 of the recess, which means that when the guide device is placed in the recess 33, the tapered shape of the recess provides a deviation compensating effect which "captures" the guide device by the wide opening 34. large "hitting surface" and the narrow bottom 35 holds or clamps the guide device securely in place. This reduces the installer's workload before final assembly, ie. before final tightening of the screws connecting the support bracket 30 and the control devices 50 and pressing these parts against the affected surfaces, in that the installer may be less careful in fitting the parts during assembly because the wider opening 34 is easier to hit.
    The guide rails 50 can run substantially parallel to the channels 20 when the guide rails are mounted in the support brackets 30. The guide rails 50 can at least partly be designed as spring clamps 51. The guide rails can also be designed as spring clamps 51 along at least parts of the rail length, or be designed as spring clamps along the entire rail length.
    The system 10 may also comprise at least one cover panel or a plurality of panels 40, and not just one panel, arranged for removable attachment to the integrated guide devices or the separate rails 50 at predetermined points on the support brackets 30. The panels may be removably attached along two parallel panel ends 41, 42 which run along the ventilation ducts 10 15 20 25 30 35 16 20 when the ducts are mounted. The panels are intended to cover the ventilation ducts and support brackets, and to at least partially cover the control devices after installation, so that the newly installed ventilation system is not so well visible, ie. the installed ventilation system must be as invisible as possible after mounting the panels. The panels 40 are bent into a cross-sectional shape substantially similar to an L seen from the side, with a portion 43 of the free ends or legs of the L bent so that the free end 43 runs in a direction perpendicular to the direction of the L. bone, and inward, i.e. the two free ends 43 of the panel may extend in a direction which, if extended, would coincide at a point opposite the connection between the bases of the legs of the L-shape. Each panel 40 shown in Figs. 1, 2, 4 and 5 has the connecting corner shaped as a chamfer, but may of course have a rectangular or curved corner as shown in Fig. 14. This chamfered shape increases the stability of panel 40. In Fig. 14, the free panel edge 43 is bent more than 90 ° towards the bracket 30, i.e. the intermediate angle between the inside of the panel 40 and the extension plane of its edge 43 is less than 90 °.
    The guide devices 50 are at least partly designed as spring clamps 51, so that it is possible to fasten the panel ends 41, 42, i.e. the free panel ends 43, removable above or in the guide devices. The guide devices can be designed as spring clamps 51 along their entire length, fastening the panels along the entire length of the panel ends 41, 42, 43. This would mean that the separate guide rails 50 form a continuous spring clamp bracket 51 (see Figs. 1-4) and that the guide devices integrated on the support bracket 30 form a discontinuous spring clamp bracket 51 (see Figs. 13 and 14). In Figs. 13 and 14, the spring clip attachment is achieved by forming the guide device 50 as a lip over which the panel end edge 43 is pressed so that the edge 43 snaps into place behind the lip to releasably attach the panel end 41, 42 to each support bracket. Either way, this means that a sufficient number of portions of the panel ends and the support devices are joined by spring clips, even if there is a distance between each bracket along which the panel ends 41, 42 are not supported. An advantage of the continuous spring clamp bracket in the form of continuous guide rails 50 is that the entire length of the ends 41, 42 of the cover panels 40 is held in place and supported so that there is no risk of bending of the surfaces of the cover panels between the support brackets 30. - the length of the rails 50 the brackets in relation to each other and along the ducts during and after assembly. The guide devices and rails 50 are therefore also arranged at predetermined points relative to each other, the support brackets 30 and the channels 20, in order to enable the support brackets to cooperate with and control the placement of the guide devices and panels 40 relative to each other. , in addition to the brackets and ducts, after mounting.
    The guide rails 50 are designed so that one end 54 of the guide rails is free and arranged to fit in the opening 34 for each recess 33 on each support bracket 30 (see Figs. 1, 2, 4 and 6). The other end 53 of the guide rails 50, when the cross section of the rail is considered, is formed by folding this free end 53 two or three times (see Fig. 9), so that an opening for a recess is formed to receive the ends 43 of the panel edges, which are opened sufficiently. , but tapers so that the double or triple folded mold 51 provides a spring clamping effect when the panel ends 41, 42, i.e. the panel end edge 43 has been inserted sufficiently far into the recess, e.g. past a certain distance into the guide rail end 53 or when it reaches the bottom of the recess (see Figs. 4 and 6). The rail 50 may be made of sheet metal and has a substantially U-shaped cross section where the free guide rail end 54 constitutes one leg of the U and runs in a plane perpendicular to the base part of the U.
    The other end 53 constitutes an extension of the second leg of the U, but is directed at a right angle, i.e. parallel to the base part of the U, and towards the other end 54, i.e. this other end 53 is perpendicular to the legs of the U and points inwards towards the U.
    The other end 53 is formed as explained above in that this end is double or triple folded so that a slit-like shape 51 is formed with a spring clamp function by a spring clamping force caused by the bent end (see Fig. 9). The guide rails 50 are preferably made of metal to give rise to the capercaillie clamping force by using e.g. bent metal sheet.
    The support and containment system 10 may also include at least one guide plate 70 arranged to be located within a joint 52 between two lengths of the guide rails 50 (see Figs. 10-12). This may be necessary when two lengths or ends of the guide rails are to be joined together, e.g. if the support rail needs to be spliced or extended with another guide rail or if the guide rail cannot pass a certain part of the wall, ceiling or floor due to the presence of a physical obstacle on the relevant surface. This physical obstacle can be a lid over an outlet, e.g. a junction box for electricity, a wall socket or some other relatively low obstacle on a wall, in a ceiling or on a floor which the guide rails pass over when they have been installed, and where said cover must be easily accessible after installation of the system 10. 10 15 20 This guide plate 70, shown in Figs. 10-12, makes it possible to cut the part of the guide rail 50 which would have passed over the low obstacle, which may be almost level with the surface, i.e. only protrude slightly above the surface, and then cut the guide plate to a length slightly longer than the cut-off part of the guide rail and fit this part of the guide plate on the inside of the cut-off guide rail or use a guide plate with prefabricated suitable dimensions (see Fig. 10 ). Then the cut guide rail part is put back together with the guide plate between the guide rails which now have two ends next to the obstacle, one end ending before the obstacle and another end continuing after the obstacle so that the guide plate extends past the inside and over the joints 52 between the guide rail ends and holds these two ends of the guide rail together in level with each other (see fig. 11). Since this guide plate 70 is detachable, the obstacle is easily accessible by first removing the panel 40 from this part of the system 10 and then the guide rail part 50 and the guide plate 70 without having to disassemble the support brackets 30 and the entire length of the guide devices 50, e.g. if an electrician needs access to the outlet later. The guide plate 70 has essentially the same shape or cross-section as the guide rail (see Fig. 12), where the only differences are that the guide plate is smaller in size to fit inside the guide rail and that the guide plate has no double or triple-folded ends as the guide rail . This guide plate 70 makes it possible to fasten the cover panels 40 to the cut-off extension piece of the guide rail 50 so that they are supported along this entire extended / spliced area.
    Each bar strip 60 may be removably attached to the panels 40 over the adjacent joint by means of at least one tab 61 which can be folded between a first position which holds the bar strip in place over the joint by gripping the panels and a second position enabling the removal of bars - the strip from the joint by detaching it from the panels (see fig. 15-17). An alternative solution may be to make the bar strips from magnetic metal sheet and removably attach them to the panels using at least one magnet. Another possible attachment of the bar strips is to combine at least one foldable tab 61 for attaching the bar strip with at least one magnet.
    Preferably, all parts, i.e. the support brackets 30, the panels 40, the guide devices / rails 50, the bar strips 60 and the guide plate 70, made of sheet metal. This reduces the weight of each part and also of the assembled system 10, so that handling, transport and cutting of the parts to desired dimensions is facilitated. In addition, if the metal plate is thin, e.g. Has a thickness of between 0.2 and 1.0 mm or between 0.4 and 0.8 mm or preferably about 0.7 mm, the work effort when cutting parts and the weight is further reduced. Furthermore, the preferred thickness also optimizes the strength and rigidity of the parts without making the separate parts and the assembled system 10 "flexible".
    Other improvements due to the innovative system 10 are e.g. that sheet metal shears and their use are well known to a ventilation fitter, whereby cutting of thin sheet metal makes it possible to ensure straight edges when freehand cutting, and above all the fitter, even if the edge is not cut completely straight, can easily maneuver the sheet metal shears and the part to be cut and compensate for any deviations. Depending on the selected metal sheet, the sheet metal scissors can also be used to bend suitable parts of the part after cutting if the shape or the cut area needs to be adjusted to fit as easily and quickly as possible, as the fitter does not need to discard any parts or use other tools to bend and adjust the part to be installed.
    The support brackets 30 can be used for ducts / pipes 20 with different dimensions to still, within certain limits, maintain a predetermined distance between wall, ceiling and / or floor and the center of the duct so that the ventilation ducts can be coordinated with other connections or adjacent ventilation systems already in place. the building. Furthermore, the predetermined distance between wall, ceiling and / or floor and duct also provides the opportunity to place insulation between the duct and the current surface in the building to reduce the risk of fire in the ventilation systems and also any unwanted noise from ventilation in operation.
    An important advantage is also that the interaction between the support brackets 30 and the ventilation ducts 20, the control devices 50, and in some cases also the cover panels 40, achieves a predetermined relationship between these parts and arranges them at predetermined points or positions relative to each other, the distance from the control devices 50 and the corner connecting joint of the cover panel 40, the walls, the ceiling and / or the floor, as well as the bevelled panel corners shown in fig. 1 for fan grilles, sockets and / or air outlets or other components is primarily controlled by the support bracket 30 by means of the control devices.
    The support bracket 30 is primarily adapted for pipes with a diameter of between 80 and 315 mm, or larger diameter, but can of course also be designed for all other dimensions since the channel receiving recess 37 10 15 20 25 30 35 20 can have the radius R adapted for all suitable duct dimensions. This recess 37 also functions as a guide and support device for the channels 20 and cooperates with the guide devices / rails 50.
    This support and containment system 10 also allows cutting by hand as only one hand is required for this due to low weight. The sheet metal scissors can be replaced with another cutting tool, e.g. a nibbling machine.
    The provision of the system 10 and the support bracket according to the invention reduces the number of components, e.g. fasteners, which constitute the system and reduce the number of tools needed to install the system into a tool for cutting parts and a tool for screwing the support brackets 30 against the actual surfaces.
    The innovative system 10 can also be used to cover vertically running ventilation ducts 20, not just horizontally running ducts, ie. the system can support and cover ducts that run from ceiling to floor or vice versa. The system 10 can also be used to cover ducts that run across a wall, ceiling or floor, instead of along a corner space, as shown in Fig. 1. In this case, the cover panels 40 must be designed to cover three sides and not just two pages displayed. The support brackets 30 would in this case also have a slightly different design similar to a U and not an L as shown.
    The bar strips 60 can be designed in a way that enables a telescopic function, ie. the bar strips may be displaceable along the panels 40 and telescopically over each other and the joints between the panels. The bar strips can also be given a panel or drapery-like design so that they can be pulled aside to cover or expose the joints between the cover panels 40.
    In the case of control devices 50 integrated directly in the support brackets 30, these integrated control devices can function as snap fasteners (see Figs. 13 and 14). In Fig. 14, the cover panel has its edge ends 43 bent towards the ends 41 and 42 so that the angle between them is less than 90 °, whereby a resilient effect is achieved, i.e. the shape of the panel 40 and its edge ends 43 allows the ends 43 of the panel edges to be pressed over and past the guide devices 50 and then removably held in place by a resilient snap fastener.
    One aspect of the invention relates to a system 10 for attaching and enclosing ventilation ducts 20 and support brackets 30 for removable attachment to walls and / or ceilings (and / or floors), the system comprising at least one support bracket, and the support bracket is arranged to be removably attached to the wall and / or ceiling (and / or floor) and the ventilation ducts, characterized in that at least one panel 40 is arranged to be releasably attached to the guide devices 50 along the channels 20 for to cover the channels and the support brackets, and the guide devices are arranged at the support bracket which runs perpendicular to the longitudinal direction of the guide rails.

Yet another aspect of the invention relates to a system 10, in which the guide devices 50 are made of sheet metal and formed by means of bending into a mold which makes it possible to fasten the panel 40 by means of spring-fastening fastening. Yet another aspect of the invention relates to a system 10, where the panel 40 is designed so that the panel can be cut by means of a nibbling tool of the desired length when it is to be mounted.
    Another aspect of the invention relates to a system 10 for attaching and enclosing ventilation ducts 20 and support brackets 30 for removable attachment to walls and / or ceilings (and / or floors), wherein the system comprises at least one support bracket, and the support bracket is arranged to be removable attached to the wall and / or ceiling (and / or floor) and the ventilation ducts, characterized in that the support bracket 30 runs perpendicular to the longitudinal direction of the ventilation ducts 20, which support bracket is arranged to keep the ventilation ducts detachably in place by means of at least a flap 31, 38 which can be folded into and out of engagement with the channels by means of a perforation 32, 32 '.
    In another aspect of the invention, a system 10 includes the tab 31, 38 which is arranged to extend over at least a part of the circumference of the ventilation ducts 20 in an unfolded condition so that it is possible for the support bracket 30 to hold the ducts in place and arranged for exposure of the ducts in folded condition, so that it is possible to detach the ducts from the support bracket.
    Yet another aspect of the invention relates to a system 10 comprising at least one or more panels 40 and control devices 50 for releasably attaching to walls, floors and / or ceilings, the panels being releasably attached to the control devices along the control devices. to cover the channels 20 and the support bracket 30, and at least partially cover the control devices. Yet another aspect of the invention relates to a system 10, in which the control devices 50 are releasably attached to the support bracket 30 at predetermined points for controlling the position of the control devices relative to each other, the panels 40 and the brackets. This enables the placement of any fan grilles, sockets and / or air intakes / outlets on the front / jacket surface of each cover panel at a distance from the control devices and any edge of the cover panel after final assembly of the system 10.
    In all aspects of the invention explained above, the guide devices 50 may be formed as separate rails. Each rail 50 may be removably attached to at least one recess 33 at the predetermined points on the support bracket 30.
    One aspect of the invention relates to a method of cutting the guide device / rail 50 by means of a sheet metal shear of the desired length before mounting. Another aspect of the invention relates to a method of manually cutting the guide device / rail 50 by means of a sheet metal scissors and then manually bending it until it comes off to the desired length during assembly. Yet another aspect of the invention includes a method of mounting the system 10 by cutting the panel 40 using a nibbling tool of the desired length prior to mounting.
    Yet another aspect of the invention relates to a method of folding the guide rail 50 into a mold at least in part along its length which enables detachable holding of a first part 54 of the guide rail against the support bracket 30 after mounting of the guide rail and the bracket. Yet another aspect of the invention relates to a method which includes removable mounting of at least one panel 40 or a plurality of panels to the guide device or rail 50 by means of a spring clip attachment to the guide device or rail at a second portion 53 of the guide device or rail, the spring clip mount being achieved by folding this second part of the guide device or rail into a clamp, e.g. by double or triple folding if sheet metal is used when the guide device / rail 50 is manufactured. In all aspects of the innovative system 10 above, the system can be used as a ventilation system, i.e. the ventilation ducts 20 may have any end or optional air outlet open inside the cover panels 40, so that air flows in at least a part of the cover system so that the panels together with other parts of the system also function as ventilation ducts. In this aspect, a slit opening which releases this air from the system can be provided by not allowing the cover panels to extend all the way lengthwise until they seal against a wall, a ceiling and / or a floor which runs e.g. perpendicular to the longitudinal direction of the ventilation ducts and cover panels. Instead, the end of the cover panel extends only to a position close to the connecting perpendicular wall / ceiling / floor, so that a free space is created between the wall / ceiling / floor and the end of the cover panel where the air can pass (think that the adjacent wall / ceiling / floor is located on the left in Fig. 2 near the channel end and the cover panel end in that area).
    In another aspect of the invention, the system 10 may be only partially installed in a room, i.e. the system may terminate on a wall in the middle of a room or in some other place relatively far from a surface perpendicular to the cover panel 40, the end of the ventilation duct 20 at this place being closed with a lid or a hood. This means that the cover panel also ends at this end, whereby a hole is made in the end which needs to be covered with e.g. a cover or lid with a similar appearance to the cover panel. These lids, hoods or covers would then e.g. is placed over the duct end and the cover panel end shown on the left in Fig. 2.
    When at least one cover panel 40 is mounted above the support bracket 30, the ventilation ducts 20 and other parts of the system 10 inside the cover panel are easily accessible because the cover panel is very easy to disassemble from the control devices 50 and the support bracket. Furthermore, the ventilation ducts are very easy to install and disassemble from the support bracket. The system 10 also enables prefabrication of cover panels with predetermined dimensions, shapes and designs. The system 10 also simplifies alignment / level adjustment between ventilation ducts that meet other ducts or ducts that run through the back of the system, ie. past the support brackets 30 and not at the front through the cover panels which would be the normal passageway, eg through rear walls / ceilings / floors, since the relative placement of the associated parts in the innovative system is predictable and predetermined in both directions . This is shown on the right in Fig. 1 with a dashed passage through an imaginary rear wall.
    The system 10 is adaptable in size, configuration, length and number of components for installation of the system, in that it includes all 10 components required for installation of the ventilation system on both the inside and outside of the cover panels 40.
    The system 10 also provides the possibility to extend, ie. move out, any electrical outlets and other outlets from a wall and / or ceiling if they should get in the way, to place the electrical outlets and the other outlets on the outside of one of the cover panels 40 instead.
    The first foot-like parts 30a, 30b are provided with the mounting holes 36. The second foot-like parts 30c, 30d have the function of pressing the guide rails 50 against the wall, ceiling and / or floor where the bracket 30 is attached and are mounted in a part of the inside of the guide rails U shape shown in Figures 1 and 3.
