    The present invention relates to a system for blocking light and / or heat energy passing through an aperture, the light blocking system comprising a length adjustable screen in the form of a blackout curtain of the type having a first side defining a first plane opposite a second side. defining an opposing second plane, said first side and second side being spaced apart by means of a spacing means, a frame constituting the edge of at least a portion of the aperture, and means for blocking light passing through a gap between at least one of the side edges of the blackout curtain and the frame,
    Light-blocking structures, such as light-blocking curtains, blackout curtains, and black curtains, are commonly used to screen openings, such as windows, for incoming light.
    For example, people who work at night need to sleep during the day without being bothered by daylight. Another benefit of light blocking curtains is that they can keep a room free of heat on hot days and help keep a room warm on cold days. So light blocking curtains provide insulation and their use can save money and energy.
    For example, light shielding is needed in offices, in cinemas, in theaters and in private homes, during events such as film and slide shows, television viewing, viewing presentations involving light sources, and similar performances and acts.
    Light blocking curtains help block 100% incoming light. The common problem with this relationship is to obtain a good fit of standard light-blocking curtains in the opening, in such a way that no spaces or light paths are left between the frame enclosing the opening for incoming light and the light-blocking curtain. free edges.
    In the past, light blocking curtains were simply a dark or black curtain or curtain where light could easily pass between the window frame and curtain because they fit poorly. In order to roll up blinds, they are always made narrower than the width of the opening, which inevitably results in spaces for light on each side of the blinds. The only way is to install the blinds on the outside of the opening instead of fitting it fully recessed into the window opening.
    More modern and better light blocking solutions have been provided since the earlier days of blinds.
    In the following description, the term "light blocking structure" is used for all types of screens, curtains or curtains. Where appropriate, these terms are used for related structures and may be interchangeable.
    An example of an improved light blocking curtain is disclosed in European Patent No. 379242 in the form of a double-walled pleated curtain. A curtain wall of folds of pleated material is connected by means of two parallel connection strips to folds in an opposite facing curtain wall, to form a joined curtain module. The module can be extruded so that the height and width of the curtain module can be determined in a simple manner, e.g. as hollow and endless lengths of material from which a suitable piece can be cut to produce the final light-blocking curtain.
    U.S. Patent No. 4,019,554 discloses a heat insulating curtain comprising a plurality of superposed, unidirectional arranged tubular members with a common slat-like partition between each of two adjacent tubular members. Each of these tubular elements has a folding fold along its two opposite sides to allow said tubular 3 3DK 2012 00142 U3 elements to be folded, thereby allowing folding of the entire curtain in the same manner as a blind, or to roll up the curtain. in a way like a roller blind.
    U.S. Patent No. 4,984,617 discloses an expandable-collapsible pleated curtain. The curtain has multicellular structure and serves to control light diffusing through the curtain.
    However, the problem remains that the gap between the side of the window frame and the outer free edges of the known blackout curtain is difficult to close effectively and allows light to pass through.
    The usual solution to this problem is to cover the gap by using a profile that protrudes from the frame that defines the opening. The profile overlaps a longitudinal area of at least one of the outside of the curtain. Typically, such a profile is U-shaped or L-shaped. In the case of a U-profile, the curtain runs between its legs. So the U's or L'ets are always outside the curtain and some light still able to penetrate the darkness through the relatively open path between the curtain and profile. There is also the problem that window openings are often out of angle, especially in older buildings. As a result, a standard light-blocking curtain's fit dimensions are often poor. In addition, incoming light is reflected by the outer surface of the U-profile or the L-profile.
    Another huge problem when using L-profiles is that the curtain can flicker if someone opens a door in a room or the window is open. Such fluttering results in very bothersome and uncontrollable exposure of light incoming spaces and the penetration of light which is experienced as generated light flashes.
    Further disadvantages of using the conventional U-profile system arranged externally on and enclosing the screen include frightening visible wear on the exterior 4 4K 2012 00142 U3 visible curtain surfaces due to friction between curtain and U-profile during the many times the curtain is raised and lowered. Another problem is that two opposing U-profiles need to be attached to the frame before the curtain is mounted, as well as that the distance between the legs of the U is a limiting factor for which types of curtain can be fitted into the window frame. If a new curtain is too thick to fit in a slidable manner between the legs of the U-profile already in place, the U-profile must be replaced with a new one with a larger space between the legs of the U to stay in able to fit the curtain edge. A double-walled pleated curtain is often thicker in the folded position than in the extended configuration. So the distance between the first plane and the second plane increases as the length of the double-walled pleated curtain is reduced. The maximum distance taken between the first plane and the second plane defines the acceptable minimum distance between the legs of the U-profile, and in conventional use, U-profiles are often chosen with a significant margin of safety.
    New light blocking curtains have different types of cell structure and air pockets that not only effectively reduce light and noise, but also provide increased insulation against heat and cold. The downside is that these improved light blocking curtains are much thicker than older light blocking curtains, so a profile that is already in place often cannot be reused. Examples of new light blocking curtains include the pleated cell structures described in the aforementioned patent documents.
    The term "spacer" includes any structure extending between opposing first and second faces of the longitudinally adjustable fret, so that the spacer is e.g. the structure connecting a pleated double-walled curtain to the opposite walls, or the zigzag fold giving the curtain a thickness, separations between slats, or any other similar means creating a distance for the light to pass between two opposing faces or planes on a length adjustable screen, such as a curtain.
    5 5DK 2012 00142 U3
    It is a major aspect of the present invention to provide an improved system of the type mentioned above to block light coming from one room or room to another.
    It is another aspect of the present invention to provide an improved system of the aforementioned type which is easy to assemble and can fit into most framed light incoming openings.
    It is a third aspect of the present invention to provide an improved system of the type mentioned above in which a profile can be used for many different thicknesses of light blocking structures.
    It is a fourth aspect of the present invention to provide an improved system of the type mentioned above which can be mounted in front of an inclined window, including skylights.
    The new and unique feature of this invention is the fact that the means for blocking light passing through said space comprise at least one groove extending into the longitudinally adjustable screen spacer between the first plane and the second plane. at least one free side edge of the longitudinally adjustable screen, and a longitudinal wedge protruding from the frame into the opening opposite the at least one groove and configured to engage said at least one groove.
    Within the scope of the present invention, a "wedge means" is a device configured with a first portion fitting into the groove made in the longitudinally adjustable screen side / side edges and a second portion serving to mount the wedge means on the opening. frame.
    6 6GB 2012 00142 U3
    Because the wedge means are inserted into the grooves, preferably in the grooves made on the opposite side edges of both the longitudinally adjustable screen, rather than being outside the longitudinally adjustable screen, the protruding first portion of the wedge is completely hidden within the longitudinally adjustable screen of the longitudinally adjustable screen. . No frightening visible wear is generated on the externally visible surfaces of the length adjustable screen. Furthermore, a coolant is suitable for curtains with many thicknesses. The only condition is that one or both side edges have a groove extending into the spacing means.
    In the preferred embodiment, the grooves may extend into the spacing means generally perpendicular to the frame in the same plane as the engaging portion of the wedge means.
    A practical light blocking system has a length-adjustable screen that can be raised and lowered freely. In conventional light blocking systems, a clearance or gap between the side edges of the length-adjustable screen and the U-profile or L-profile, and thus the frame, serves this purpose, but this clearance or gap allows light to pass between the frame and the length-adjustable screen. . Such clearance and spacing are e.g. between 2.5 mm and 5 mm. The light to be blocked can be either natural light or artificial light.
    Instead of placing the clearance or gap between the length adjustable screen and the wedge means within the length adjustable screen, as in the present invention, it is possible to use wider length adjustable screens than in similar conventional light blocking systems mounted in e.g. U-profiles. Preferably, the length adjustable screen is as wide as the opening, and all cracks that allow light to pass between the frame and the length adjustable screen are substantially eliminated.
    7 7GB 2012 00142 U3 In conventional light-blocking systems, input of incoming light can also be caused by an inevitable light path created by the overlap and gap between the U-profile or L-profile and the length-adjustable screen, or due to light reflected by U the outer surface of the profile or L profile.
    So, in conventional light blocking systems, the light input and output of the light path are located far farther from the frame than in the inventive system, in which the free side edges of the longitudinally adjustable screen are precisely adjusted to be in close proximity to the frame and the track-engaged wedges. a very superior light barrier is achieved.
    To achieve the best possible control by lowering and raising the length adjustable screen, as well as the best possible light blocking capacity, the frame can be provided with opposing first and second longitudinal wedges projecting from the frame, and the blackout curtain has first and second slots in the blackout curtain. respective free side edges, said slots are configured to engage with said respective first and second longitudinal wedges. In this configuration, light blocking can occur equally well on both free sides of the length adjustable screen, and the length of the length adjustable screen can be adjusted unobstructed by using the wedge means as a guide rib.
    In a simple embodiment, the length adjustable screen is merely a pleated curtain made of a single sheet of material, the spacer being created during zigzag folding of the sheet. In this embodiment, the spacing means is folded between opposing vertices on the pleated folds.
    In another simple embodiment, the length adjustable screen can be like a harmonica.
    In an alternative embodiment particularly suitable for blackout curtains, noise-canceling installations, and heat energy controlling installations, the length-adjustable screen may be a double-walled pleated curtain and the spacer configured as an open cell structure. Suitable examples of double-wall pleated curtains include, but are not limited to, the examples discussed above in connection with prior art patent documents.
    Many different types of spacers consisting of open cells or associated layers of open cell structures are contemplated within the scope of the present invention. In a preferred embodiment, the shape of a cross-section of an open cell, taken in a plane parallel to the side edges of the length-adjustable screen, may be polygonal, preferably hexagonal, to create a honeycomb-like length-adjustable screen structure.
    The pleated cell structures may e.g. are made from stacked and interconnected tubes with honeycomb-shaped cross-sectional area, however, any cross-sectional area including, but not limited to, square or even asymmetric polygons is within the scope of the present invention. One or more transverse layers of stacks of tubular structures may also be combined. A light blocking honeycomb curtain is a very energy efficient version of a light blocking plissé structure with hexagonal tubular cells placed side by side.
    The hexagonal honeycomb cross section creates a grid of cells using the least amount of material to achieve high volume between the first and second surfaces of the length adjustable screen. The first surface and the second surface may also be substantially flat flexible sheets interconnected and divided by transverse strips or strips. In such a simple system, the length-adjustable screen may be composed of stacked tubular cells with square end openings and square cross-sectional areas. The contacting sides of the square tubes can serve to attach the tubes to each other to form partitions between the open cells to form a length adjustable screen. The joined pipe sides that create the partitions are spaced apart.
    An advantage of curtains, blinds or screens made of a large number of stacked tubes or cells with honeycomb-shaped cross-sectional area is that two interconnected hexagon sides provide a flexible joint, and the parallel hexagon sides between opposing flexible joints may serve to secure the tubular hexagonal cells on top of each other to form the partitions between the open cells. In this design, a length-adjustable double-wall pleated screen is formed, and the hexagon's joined opposite sides make up the spacer.
    Slots or recesses can be made by simply making an incision in the side edges of the pleated curtain. For example, grooves can be made by punching or laser cutting through the folded length adjustable screen along the side edges a distance into the spacing means. More than one groove may be provided on a side edge to cooperate with several protruding means on the wedge means.
    The preferred design of grooves and engaging wedge means is simply a suitable wedge including a flat tab slid into a corresponding, generally complementary, rectangular groove, or in any other groove of suitable shape. The groove can have a depth of between 1.5 cm and 3 cm and a width between 0.3 cm and 1.0 cm.
    The flat tab may conveniently be at least part of a T-shaped, L-shaped or U-shaped wedge, but many modifications of shapes are contemplated by the present invention. The groove can be given any shape completely complementary to, partially complementary to, or not complementary to the design and shape of the first part of the wedge means. For example, the first portion of the wedge means could be dovetail-shaped, Y-shaped, or have a rounded free end, and the bottom of the groove may be complementary to further ensure that incoming light does not pass through. However, first source parts having this configuration can all fit sufficiently well into a suitably sized rectangular or tapered groove. The advantage of having an enlarged end of the wedge means means that the wedge means and grooves are not inclined to disengage from each other.
    The coolant can be attached to the frame by means of an adhesive to facilitate easy assembly, replacement and removal. The need to drill holes in the frame is eliminated and assembly time is significantly reduced. The coolant may e.g. be extruded plastic profiles provided with an adhesive having an adhesive strength selected to attach the profile to the frame. A detachable protective liner can protect the adhesive during storage and before the wedge adhesive is adhered to the frame.
    The frame surrounding and defining the opening may be selected from the group comprising a window frame for a window, a frame around an artificial light source, a door frame, a frame for a skylight, a window frame for a rocker window, a top hinged window frame or a frame. to a space divider so that the frame useful in the system of the present invention may be any frame surrounding an opening e.g. a wall, notwithstanding that said opening is covered by a pane or similar means.
    The preferred length adjustable screen is a blackout curtain optionally provided with additional light blocking properties such as dark color, coatings, many different or even layers, etc., including materials containing silver or a silver compound.
    In one embodiment, the longitudinally adjustable screen is hoistable by means of curtain ropes arranged between the first and second planes and drawn wall from the free edges, leaving space for making grooves for grooves.
    In another embodiment, the length adjustable screen is cordless and the grooves may have any depth that does not compromise the structural integrity and functionality of the length adjustable screen.
    In the event that the system of the present invention is to be used in areas and locations outside of manual range, a motor may be provided to raise and lower the length adjustable screen.
    The length adjustable screen may have means for attaching the length adjustable screen to the frame, which means includes a top rail, and optional means for weighing the length adjustable screen down, optionally a bottom rail wherein one, both, or neither of the top rail or bottom rail. has bristles to close the gap between track and frame.
    In one method, the above-described system is mounted, which comprises providing a length adjustable screen having at least one groove extending into the longitudinal adjustable screen spacing between the first plane and the second plane from at least one free side edge of the length adjustable providing a longitudinal wedge means configured to engage said at least one groove, mounting said wedge means on said frame with a portion of said wedge projecting outwardly from said frame into said aperture, and mounting said longitudinally adjustable screen having said groove; so that the wedge means engages with the longitudinally adjustable screen facing each other at least one groove.
    By the method of the present invention, effective blocking of light and / or heat passing through an opening framed by a frame can be achieved in a simple, effective and visually elegant manner. The length-adjustable 12 12GB 2012 00142 U3 screen can be raised and lowered in a controlled manner because at least part of the wedge means engages in a cooperating groove, which not only creates a barrier to light, but also keeps the length-adjustable screen in a plane that is mainly flush with or parallel to the aperture regardless of unforeseen surrounding, affecting variables such as positive or negative air pressure changes close to the length adjustable screen, or the angle of the frame.
    The invention will be described in more detail below with reference to the drawing, in which 1 is a fragmentary perspective view of a corner of one embodiment of a system of the present invention; 2 shows, slightly enlarged, the same in overall condition; FIG. 3 is a sectional view taken along line III-III of FIG. 2, the system in fragmentary section, illustrating the engagement between the longitudinally adjustable screen grooves and protruding parts on the corresponding wedge means; and FIG. 4 is a plan view of the system of FIG. 2 with the length adjustable screen fully submerged so that the bottom rail rests on the bottom frame.
    The figures of the drawing schematically illustrate the light blocking principle and system of the present invention by means of an exemplary embodiment, which is not to be construed as limiting the many modifications, variations and uses described above.
    Accordingly, the invention will be exemplified below in relation to a vertical, pleated, wireless blackout curtain in front of a vertical window pane, but could equally well have been described in relation to another framed opening without a pane, having a horizontal cord, being horizontal or be suspended in front of the opening in a top hinged window frame at an angle of e.g. 45 °.
    The components of the system 1, seen in a fragment in the exploded view of FIG. 1, includes a frame 2 defining a window opening 3. A window 4 (not shown in Figure 1) is mounted in the window frame 2 to cover the opening 3. How the window 4 is mounted in the window frame 2 is not part of the invention and is therefore shown schematically only.
    The system further comprises a length-adjustable pleated screen 5 and a wedge means 6 in the form of a longitudinal T-profile 6. The T-profile 6 consists of a first part 7 which, in the case shown, has a longitudinal tab 7 extending perpendicularly from a second one. part 8, in the case shown, a flat head 8 on the T.
    The length adjustable pleated screen 5 consists of a large number of tubular structures 9 with hexagonal cross sections AH. The tubular structures 9 are joined, one on top of the other, to form the length adjustable pleated screen 5. The length adjustable pleated screen 5 has a span that completely covers the opening 3 and the window pane 4 when the length adjustable pleated screen 5 is in its lower position. . That is, the length-adjustable pleated screen 5 must include so many tubular cell structures 9 that the length-adjustable pleated screen can span the distance between the top (not shown) of the frame 2 and a bottom portion 10 of the frame 2 when the length of the adjustable screen 5 is stretched out. As the length adjustable pleated shield 5 is lowered, its tapered edges 11a, 11b on respective opposed first face 12a and second face 12b define respective opposing first face 13a and second face 13b, respectively. The width of the length adjustable screen 5 is selected to be substantially the same width as the frame opening 3, although a small difference is acceptable to account for or compensate for parameters such as sloping angle frames and the size and dimension of the second part of the wedge 6. between the width of the length adjustable pleated 14 5GB 2012 00142 U3 screen 5 and the frame opening 3, ie. however, the lateral clearance C between frame 2 and length adjustable pleated screen 5 may not be so small that the blackout curtain cannot be operated unobstructed.
    When the hexagonal tubular structures 9 are combined into the longitudinally adjustable pleated screen 5, joined neighboring surfaces 14 of the tubular cellular structures 9 define an inherently integrated spacer 15 which provides distance between the first plane 13a and the second plane 13b and provides the length adjustable pleated screen 5 .
    Since, for illustrative reasons, only a fragment of the system 1 in Figures 1 and 2 is shown, only the first edges of the longitudinally adjustable pleated screen 5 are visible. However, it should be understood that an opposing second side edge 16 is constructed similarly. Both side edges 16 have a groove 17. As seen better in FIG. 3, the track 17 is oriented opposite and engaging tab 7 on the respective wedge means 6. A track 17 is e.g. 2 cm deep and manufactured using a suitable punch punch (not shown) to punch through the spacer and tubular structure 9 wall along the side edges 16 of the longitudinally adjustable pleated screen 5 when in the folded state.
    The length adjustable screen 5 also has a bottom rail 18 for weighing down the length adjustable screen 5 as it is lowered, and a top rail (not shown) for mounting the length adjustable screen on an upper frame portion (not shown).
    FIG. 2 shows the system 1 in the overall state in which the wedge means 6 is fixed in a vertical position to a vertical frame portion 19 of the frame 2, e.g. simply using an adhesive (not shown). Any other fastener can be used, including screws and nails.
    The tab 7 of the wedge means 6 projects into the overlying groove 17 of the spacer 14 in the double-walled length adjustable 15 side edge 16 of the screen 5. The opposite side edge 16 (as shown in Fig. 3) is arranged in a similar manner, allowing the length adjustable pleated screen to be guided up and down by tab 7 in a generally vertical plane in front of pane 4, to cover said pane if darkening is needed.
    The tab 7 of the wedge means 6 is not visible in the extended configuration of the longitudinally adjustable pleated screen 5. The tab 7 is received inside the groove 17 and is hidden between the first and second screen sides 12a, 12b. So, tab 7 is not exposed to incoming light and no unpleasant light reflections are emitted from the wedge means 6. The space C between the side edges 16 of the screen 5 of the frame 2 is secondary.
    As seen in the overview image in fig. 4, the length adjustable screen 5 fits neatly over the area of the window opening 3. The side edges 16 of the length adjustable screen 5 are very close to the frame 2 because the length adjustable screen 5 overlaps tab 7. Light is completely prevented from passing from the first plane 13a to the second plane 13b.
    In order to be able to show the small details relevant to the function of a large system, only a fragment of the system 1 is shown with a corner of the frame 2 in Figures 1 and 2. Figs. 3 indicates the symmetry of the system 1 at the opposite side edges 16. As shown particularly in FIG. 3 and FIG. 4, the spaces C between the side edges 16 of the longitudinally adjustable screen 5 and the frame 2 are extremely small and blocked by the longitudinally engaging tab 7, so that light is significantly prevented from passing.
    A pleated screen or curtain for a frame for a top hinged window needs to be extended at an oblique angle. The method used today is reinforcing and retaining the screen or curtain side edges 16 of each other using steel wires or ropes. The wires are mounted in the 16 16GB 2012 00142 U3 corners on a top strip or the corners on a top piece and the pleating is attached to said top strip or top rail. Holders at the corners of the bottom frame serve to secure the wires to keep the screen extended and flush with the window opening. Although this technique is good, it is cumbersome and requires the wires, ropes, or cords to be stretched and held tight. Ropes or cords that are held tight tend to relax over time and require frequent, costly re-tightening.
    Instead, if system 1 of the present invention is implemented in the frame of the top hinged window, tab 7 of wedge 6 holds the pleated screen in the angled position, e.g. between 0 ° and 90 °, and often 45 °. So the wedge means is a simple means to prevent the screen from falling to a vertical position and to keep the screen flush with the opening, ie. with the pane.
    The largest angle relative to the screen width depends on the type of screen material. If the pleated screen material is of the type where the distance between the first plane and the second plane is about 25 mm, a screen having a width of e.g. 120 cm, mounted and operated at an angle of about 30 °.
    The screen 5 of the inventive system 1 is easy to mount on any frame type 2. The screen 5 can be mounted fully recessed in the frame or simply partially recessed in the frame. The screen can even be mounted outside the opening, e.g. by using an L-profile where the long leg serves as the first part 7 of the wedge means 6 corresponding to tab 7, and the short leg serves the same function as the second part 8 of the wedge means 8, corresponding to the head head 8.
    The new system is easy to install, does not require repair or re-adjustment, and can be used for darkening of light passing through a large number of openings, including but not limited to window openings.
