    Ladder The present invention relates to a ladder, in particular to a extendable ladder comprising at least two collapsible step segments, and to such step segments.
    Ladders are used for different types of work, for example p5 house facades. Many ladders are extensible, in that at least two step segments are telescopically or displaceably arrangable in relation to each other and are soluble in a layer where together they form a continuous ladder which is longer than the individual segments. Such a ladder can thus offer the possibility of reaching further up and at the same time collapsing or sliding together to take up less space during storage.
    Many work steps require access to various utilities that are supplied via long-distance supply devices. Typical examples include water for rinsing and washing, supplied via a water hose; and electricity for the operation of hand tools, supplied via a cable. Other uses may also occur, such as compressed air for cleaning or operating hand tools, supplied via a pressurized air hose.
    For such work there is a problem in handling the supply device, especially when the supply device leads to a hand tool which is used by the user for said work. The supply device itself can be heavy, especially when it is filled with a utility such as water, but can also become entangled in the user and the steps. This also makes a possible hand tool awkward and difficult to handle.
    These problems are conventionally solved by fixing the supply device temporarily, such as with the aid of a knot, cable tie or the like, on the supply device itself, if its flexibility allows this, at the top of the steps. However, this solution is neither reliable nor practical, especially with extendable ladders.
    The present invention offers a better solution to the problems described above.
    Thus, the invention relates to a step segment comprising side profiles and step pins, wherein at least one of said side profiles Jr a hollow metal profile with a first and a second spirit, the step segment further comprising an elongate, integrally arranged in the step segment, comprising a first and a second spirit, which supply device is arranged to supply a utility Iran its first spirit to its second spirit, which step segment is defined by said metal profile comprising sliding at its first and second spirit, respectively, by the supply device running inside and along with the metal profile between said slides, in that the supply device in its first and second spirit respectively comprises terminating first and second connections of standard type which are arranged to be accessible for connection outside the metal profile, in that the step segment is arranged to be joined by a further step segment to form a joint comprising a further supply device, and in that the supply device is arranged to be connected to said further supply device to form a coherent supply device.
    In addition, the invention relates to a method for equipping a step segment or a ladder, comprising at least one hollow side profile of metal with a first and a second end, with a supply device arranged to supply a utility from the first end of the supply device to the second end of the supply device, which method marked by the fact that the method comprises arranging hl at the first and second spirits of the metal profile, mounting the supply device so that it runs inside and along the metal profile between said hl, and providing the supply device in its first and second spirits with terminating first and second and second, respectively. standard type connections which are arranged to be accessible for connection outside the metal profile.
    Such a method thus constitutes a manufacturing method for such a step segment or such a ladder according to the invention.
    The invention will now be described in detail, with reference to exemplary embodiments of the invention and the accompanying drawings, in which: Figure 1 illustrates a ladder or a step segment according to the invention; Figure 2 illustrates a ladder according to the invention, comprising two joined step segments according to the invention. The steps shown in Figure 2 are in the extended state, ready for use; Figures 3a and 3b illustrate a detail of a ladder according to the invention, comprising an extraction device according to the invention, in a retracted (figure 3a) and an extended (figure 3b) condition, respectively; and Figure 4 illustrates a stopping device according to the invention, with a supply device and associated stopping means in two different possible layers (one upper and one lower).
    The figures share male reference numerals for the same parts. The step segment 100 shown in Figure 2 is the same step segment shown in Figure 1. The step segment 200 shown in Figure 2 has the same reference numerals as for corresponding parts in Figure 1, but with an introductory number "2" rather than "1", which is the case for the step segment 100. The details illustrated in Figures 3a, 3b and 4 Jr are not to scale.
    Figure 1 thus shows a step segment 100. The step segment 100 may be used in conjunction with one or more additional step segments 200, as illustrated in Figure 2, to provide a composite ladder 300. Alternatively, the step segment 100 may itself be formed, and d5 constitutes a ladder 100 as such. .
    What is said here regarding the step segment 100 is also applicable to the step segment 200, which later is therefore not described in detail in all parts. A difference between the segments 100, 200 Jr, however, is that the Jrs are mutually adapted in order to be able to be adjusted in a stable manner, which presupposes suitable engaging or joining means which are in themselves conventional. Figure 2 illustrates the common and preferred case of a segment 200 Jr narrower than another step segment 100, in order to achieve extensibility between the segments 100, 200. It is understood, however, that different types of interventions may be relevant, depending on the application.
    The step segment 100 comprises side profiles 101, 102 and step pins 103. It is preferred that the step segment 100 Jr be made of metal, especially in the form of solid metal profiles, such as Ansolmingstext 2014-02-140084SE 4 aluminum profiles. At least one of said side profiles 101, 102 is in itself a hollow metal profile with a first (bottom in the figures) and a second (up in the figures) Jnde, which side profile 101, 102 is arranged to house a supply device 110, 120 according to the invention, which detailed in the following.
    Such a supply device 110, 120 Jr according to the invention is arranged to supply a utility from an external Ulla, from said first spirit to said second spirit, for use in work on the steps. Such utilities can be liquid, gaseous or field-based / articulated. Examples include tap water, hot water, blaster water, paint for spray painting, pressurized gas such as inert gas such as compressed gas or compressed air, as well as electric span electricity, and further. The important thing is that the elongate supply device 110, 120 on something sat arranged to carry the utility from an external Ulla, such as a water post; a tension skull; a water hose connected to a water post; or an extension cable which is connected to a tension head, Wigs with the supply device 110, 120 and up to a stable along the step segment 100 where the utility is used by a working user.
    According to the invention, each step segment 100, 200 is arranged to be joined by a further step segment 200, 100, wherein or all of the joined step segments 100, 200 Jr of the type defined in any one of the claims, to form the continuous step 300. the supply device 110, 120 arranged to be connected to the further supply device 210, 220 which forms part of the second step segment to form a continuous supply device. Figure 2 illustrates two such contiguous supply devices 110 + 210, 120 + 220.
    It will be appreciated, however, that each individual step segment's individual supply device is arranged to carry a respective utility Iran either an external Wool or from an adjacent step segment, and to a hand tool or the like or to an adjacent step segment.
    According to the invention, said hollow metal profile 110, 120 comprises a respective hall 101a, 102a at its said first spirit and a respective hall 101b, 102b at its said second spirit. It Jr f5redraget att halen 101a, 102a Jr arranged at most 1 m from said Ansolmingstext 2014-02-140084SE first spirit, rather at most 0.8 m from spirit. Above all, it is preferred that the cavities 101a, 102a are arranged at the first second but at a distance therefrom and with an orientation which means that the cavities 101a, 102a in question are free from another step segment 200 together with which the step segment 100 is used to form a ladder 100, as exemplified in Figure 2.
    The supply device 110, 120 is further arranged so that it runs inside and Wigs with the metal profile between said h51 101a, 101b; 102a, 102b. In addition, the supply device 110, 120 terminates in its first (down in the figures) and second (up in the figures) end in the first 112, 122 and other 114, 124 connections of standard type, respectively, which are arranged to be accessible for connection outside the metal profile 110. , 120. In other words, the connections 112, 114, 122, 124 are arranged so that a standard connector, such as a water hose connection or a socket, can be connected to the respective connection 112, 114, 122, 124 at a stable which is easily accessible from the outside. step segment 100, that is to say from its outside. It is possible for the connections 112, 122, 114, 124 to be integrated or recessed in the step segment 100, as in any of the side profiles 101, 102, but it is preferred that the entire respective connection 112, 122, 114, 124 be arranged completely outside the side profiles. 101, 102 and the rungs 103.
    Such a step segment 100 contains at least a part of the supply device 110, 120, preferably more than half of its total length, which supply device 110, 120 is guided through the longitudinal metal profile 101, 102 of the step segment 100 from one end of the step segment 100 to its other end, and exposes in each respective spirit a respective connection 112, 114, 122, 124. This confers several advantages.
    First, any other user can easily connect the utility at the base of the step segment 100 (neclat in the figures), as well as a hand tool or demand supply device at the top of the step segment 100 to utilize the utility there. This can be done in a way that does not require the user to carry a heavy water hose or the like during the work; that unreliable knots or the like need to be used to support the supply device 110, 120; Ansolmingstext 2014-02-140084EN 6 and without risk of entanglement of the supply device 110, 120 in the step segment 100 or the user during handling.
    Secondly, such a step segment is easy to produce from one or more existing conventional step segments, or an existing conventional ladder, of the type frequently occurring on the market, as described below.
    Third, several step segments 100, 200 of the type described above can be easily joined together to form a coherent, longer ladder 300 (Figure 2) with correspondingly good properties in terms of accessibility of said utility when working at different heights on the steps 300 in question.
    According to a preferred embodiment, the connection 112, 114 at the first, lower end is arranged to be connected to an external supply device of standard type (not shown in the figures) for the purpose in question. Such a supply device can for instance consist of a water post, an electrical outlet, a supply point for compressed air, and so on. An extension device, such as a requesting water or compressed air hose, or an extension cable, can also be used between the Ulan and the connection 112, 114.
    When it comes to the connection 114, 124 at the second, upper spirit, it is preferably arranged to be connected directly to a hand tool (not shown in the figures), alternatively to a supply device of the demand type, for delivery of the utility in question. Connected supply devices, which may be of the extension type or be directly connected to a respective nozzle for the utility in question or to a hand tool, are indicated in Figure 2, with male reference numerals 10 and 11.
    In the preferred example in which the supply device 110 is a water hose (see left side profile in Figure 1), the first connection 112 is preferably a female-type water hose connection, and the second connection 114 is preferably a male-type corresponding quick-connect.
    Ansolmingstext 2014-02-140084EN 7 In the preferred example in which the supply device 120 is an electrical cable (see the right side profile in Figure 1), the first connection 122 is a standard male type socket, and the second connection 124 is preferably a standard female type socket. Corresponding grids, as well as everything else stated here in no other case, for the step segment 200.
    Other types of utilities require other types of connections. A compressed air supply device could, for example, comprise a first / lower standard female type quick connection for compressed air, and a second / upper standard male type quick connection for compressed air.
    As illustrated in Figure 1, it is preferred that the steps 100 comprise two different types of supply devices 110, 120, in the present example a 110 for water and a 120 for electricity, arranged in and Wigs with different respective hollow metal side profiles 101, 102 included in stegen.
    When it comes to the lower holes 101a, 102a, at the said first / lower spirit, it is preferred, and as is the case for the step segment 100 illustrated in Figure 1, that the hAlet & Aga is arranged in the mantle surface of the metal profile 101,102, preferably p5 out, front or back of the metal profile 101, 102 in relation to the step pins 103. In other words through the surface as in figure 1, and for example the metal profile 101, facing left, out of the paper or into the paper.
    When, on the other hand, the second / upper Mien 101b, 102b applies, it is preferred that the tail according to the arrangement is arranged in the face surface of the metal profile 101, 102, i.e. the upper face facing up in Figure 1.
    Such an arrangement of [Alen 101a, 102a, 101b, 102b means that the respective supply devices 110, 120, 210, 220 can be connected in a simple manner when several step segments 100, 200 are to be assembled into one and the same continuous step 300, as shown in Figure 2, p5 is a set going to the supply devices 110, 210; 120, 220 together form a respective continuous supply device along the length of the step 300.
    In addition, storage is facilitated in step 300 collapsed / collapsed states.
    Ansolmingstext 2014-02-140084EN 8 According to a preferred embodiment, the lower / first spirit 111, 121 of the supply device 110, 120, which protrudes from the lower / first cavity 101a, 102a, is free, as illustrated in the figures. In particular in combination therewith it is preferred that the second / upper spirit 113, 123 of the supply device 110, 120 is permanently fixed to its respective metal profile 101, 102, as well as to its outside.
    This means that the step segments 100, 200 can be joined to a continuous ladder 300 and that the supply devices 110, 210; 120, 220 can be joined together in a particularly simple and reliable manner, which also means that the Ulan described above and the hand tool can be connected. The step segments 100, 200 are held together via the conventional joining means of the step 300 (see above), which allows the connection between the supply devices 210; 120, 220 are not loaded when the steps 300 Jr mounted.
    It is further particularly preferred that the second terminal 124 has a branch connection, as illustrated by the electrical connection in the power cable 120, which in the illustrated example comprises three female and standard type socket connections.
    In addition, the step segment 100 preferably includes fasteners 101c, 102c, at the lower / first end of the respective metal profile 101, 102, so as to releasably secure the first connection 112, 122, preferably by releasably holding the spirit 111, 121. For example, and as illustrated in the figures, the fastening means 101c, 102c are constituted by a simple metal hook or metal clamping means, which may be attached to the metal profile 101, 102, as by welding.
    According to a preferred embodiment, the cavity 101a, 102a at the lower end of the metal profile 101, 102 is too small for the first connection 112, 122 to pass through said 1151101a, 102a, which means that the first spirit 121 of the supply device 110, 120 cannot be rimmed into the metal profile 110, 120 through said h51 101a, 102a. Corresponding 011s are preferably also for the second / upper tail 101b, 102b and the second connection 114, 124.1, especially if the upper connection 114, 124 is not fixed to the metal profile 110, 120. This means that the supply device 110, 120 is held in place in a particularly simple construction.
    As illustrated in Figure 2, the invention thanks to a ladder 300 comprising a first 100 and a second 200 step segments as above, the step segments 100, 200 Jr being arranged to engage each other in a layer where the first step segment 100 Jr a is north of the second 200 longitudinal (downAt in Figure 2), to form steps 300 in assembled condition. The steps 300 may be of telescopic, launching or some other conventional construction per se, which is not described in further detail here. The first respective connection 212, 222 Jr of the second stage segment 200 is arranged to be connected to the second connection 114, 124 of the first stage segment 100 so that the supply device 110, 120 of the first stage segment 100 together with the supply device 210, 220 together of the second stage segment 200 form a cohesive supply device. By means of this integrated supply device 110, 210; 120, 220, the utility can thus be guided from the lower end of the step 300 to its upper end.
    In addition, in case at least one segment 100, 200 comprises a branch connection 124, 224 as above, the utility can be taken out in several parallel rivers, and if desired also in the other stables Wigs with the steps 300 at the top, as at 124.
    The construction described above with a free spirit 112, 122; 212, 222 in combination with a fixed spirit 114, 124; 214,224 allows simple and things connection at the same time as a certain clearance is allowed to mount the steps 300 of different lengths, by adjusting the longitudinal layers of the different step segments 100, 200 in relation to each other.
    According to one aspect of the invention, a ladder 300 of the type described above is manufactured with a supply device 110, 120, 210, 220 arranged to supply a utility Irk 'an external from the first / lower spirit to the second / upper spirit, for use when working on steps 100, 200, 300 according to a manufacturing method according to the invention. Such a manufacturing process takes place from a number of existing step segments or an existing ladder, preferably of conventional type, comprising at least one hollow side profile of metal Ansolmingstext 2014-02-140084SE 10 with a first and a second spirit. Preferably, each step segment 100, 200 comprises at least one such side profile.
    Such a manufacturing method comprises arranging the tail 101a, 102a, 101b, 102b; 201a, 202a, 201b, 202b at the first and second / free spirits of the metal profile, respectively; mounting at least one supply device 110, 120, 210, 220 so that it runs inside and Wigs with the respective metal profile 101, 102; 201, 202 between said halls 101a, 101a; 102a, 102b; 201a, 201b; 202a, 202b as described above; and providing the supply device 110, 120 in its lower part 111, 121; 211, 221 and andraiiivre 113, 123, respectively; 113, 223 spirit with concluding and first 112, 122, respectively; 212, 222 and others 114, 124; 214, 224 standard type connections as above, which are arranged to be accessible for connection outside the metal profile. In addition, any fixed means 101c, 102c; 201c, 202c are mounted by means of welding, screwing or the like.
    The supply device 110, 120; 210, 220 are preferably per se of the standard type, such as a conventional garden hose for water or a conventional electric cable with shielding and waterproofing intended for outdoor use.
    This offers a very fast, easy and cost-effective way to provide a ladder 300 according to the present invention, based on step segments or a ladder of conventional standard type.
    Figures 3a and 3b illustrate a preferred embodiment, according to which a supply device 120 which is substantially narrower than the space inside and along the side profile 102 in which the supply device runs from, is partially extendable and retractable out of and into said space by means of an extraction device 130. It is especially preferred that such a narrow supply device 120 be an electrical cable, but it is also possible that other types of supply devices may be used in conjunction with such extraction devices. "Substantially narrower" means, in this context, that there is sufficient space inside the side profile 102 for the supply device to be able to slacken at least 50 cm, and be drawn into said space corresponding to the distance, and to have space in the space.
    The extraction device 130 comprises an elongate, elastic part 131, such as a rubber band, which is fixed to the side profile 102 at a first fixed point 131a, as farthest as the side of the side profile 102, and at the supply device 120 at a second fixed point 131b. , as near the tail 102a.
    Figure 3a illustrates the elastic part 131 in a slack condition, in which it has retracted the supply device 120 a distance, such as at least 50 cm, in comparison with the fully extended condition of the supply device 120, which is illustrated in figure 3b. In Fig. 3b, the elastic part 131 is thus stretched and applies a upwardly directed tensile force in the figure to the second fixed point 131b. In the fully retracted layer illustrated in Figure 3a, the supply device 120 protrudes 121 at least about 5 cm from the tail 102a. In the fully extended layer illustrated in Figure 3b, the supply device 120 preferably protrudes 121 at least this piece by at least about 5 cm and in addition a further at least 50 cm, and in any case so far that the supply device 120 can be connected to a corresponding supply device on an adjacent step segment, in the case illustrated in Figures 3a and 3b by connecting the contact 122 of the power cable 120 to the corresponding socket, as explained above.
    It is preferred that a stopping device be used to define said fully extended bearing, including cooperating stopping means 132, 133, fixedly mounted on the supply device 120 and the side profile 102, respectively. The stopping device is arranged to releasably retain the supply device 120 in said fully extended bearing, so that connection to an adjacent step segment can be accomplished in a convenient manner and maintained in a reliable manner. Figures 3a, 3b and 4 illustrate an example where the stop means 132 is constituted by a permanently attached abutment on the supply device, arranged to engage and cooperate with a specific shape 133 (illustrated in figure 4) of the tail 102a. Because the stop means 133 forms an integral part of the properties of the Wets 102a, it is also "fixedly mounted" on the side profile 102 within the meaning of the invention.
    Ansolmingstext 2014-02-140084EN 12 The supply device 120 runs freely through both a relatively narrower part 133b of the hole 102a and through a relatively wider part 133a of the hole 102a, which parts 133a, 133b constitute tv5 integrated and coherent parts of one and the same h51 102a ( see Figure 4). The stop member 132, on the other hand, is larger than the relatively narrower part 133b, and can therefore act as an abutment against the outside of the side profile 102, where it is pressed against the side profile by the tensile force of the elastic part 131, thereby defining the fully extended layer and uppratthAlls (see the lower part of figure 4 and figure 3b). In contrast, the stop member 132 can run freely through the relatively wider portion 133a (see the upper portion of Figure 4).
    Thus, the supply device 120 is pulled from the layer illustrated in Figure 3a to the layer illustrated in Figure 3b, by pulling the stop member 132 through the wider portion 133a of the hole 102a. Then the stop means 132 is moved to the team illustrated in Figures 4 (lower part) and 3b, and the connection with the adjacent step segment is established. When the steps are to be disassembled again, the connection is broken, the stop means 132 is moved to the layer illustrated in Figure 4 (upper layer), through the wider part 133a of the hole 102a, after which the supply device Ater is moved to the layer illustrated in Figure 3a.
    Such a pull-out device offers a simple and reliable way of handling protruding spirits 121 having delivery devices 120 during storage and transport.
    Above, preferred embodiments have been described. However, it will be apparent to those skilled in the art that many changes may be made to the described embodiments without departing from the spirit of the invention.
    For example, the step segments 100, 200 may have other dimensions or number of step pins 103 than what is illustrated in the figures.
    More than two step segments 100, 200 can also be joined to an even longer step 300, in a corresponding manner as described above in connection with steps 300.
    Ansolmingstext 2014-02-140084EN 13 The figures show ladders with both water and electricity supply. It will be appreciated that, for example, only one supply device, or tv5 supply devices of the same type, or other combinations of one or tv5 same or different supply devices, are also possible according to the present invention.
    Thus, the invention should not be limited by the described embodiments, but may be varied within the scope of the appended claims.
