Description

Technical Field

[0001] The present invention relates to a holding device for holding one or more cables. Such a holding device generally holds a cable in a predetermined position and is usually used together with the transit of the cable through a partition, which is, for example, a partition such as a building floor or roof or other types of partitions, in which the cable is wired from one side of the partition to the other side, for example, between floors, from inside the building to the rooftop. For example, such a holding device can be used to hold a cable sent from inside a building to the rooftop. Also, such a holding device can be used to hold a cable in other positions, such as in a cabinet, duct, shaft, or other suitable positions. The present invention also relates to a holding system and a holding method for holding one or more cables. The present invention also relates to the use of such a system.

Background Art

[0002] Attaching the transit of the cable to the rooftop and other positions can sometimes be difficult. Usually, it is desirable to provide a proper seal around the cable and hold the cable in an organized manner in a predetermined position. Further, it is preferable to simplify the installation process for the operator. The problem with conventional technical means is that it is usually necessary to transfer the cable to another cable or a smaller and more flexible cable before connecting the cable to other devices in various types of systems. When the cable needs to be changed, another problem arises. Therefore, there is room for improvement regarding conventional devices and systems for holding cables and attaching cable transits to rooftops and the like.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The object of the present invention is to provide novel holding devices and systems that are improved over the prior art. This object is achieved by the art described in the appended independent claims and preferred embodiments defined in the related dependent claims. [Means for solving the problem]

[0004] According to one embodiment, a retaining device for holding one or more cables is provided. The retaining device includes a support bracket having at least one end piece having a recess; a back piece; a locking device configured to move through the recess of the support bracket in cooperation with the back piece; and at least one compressible module having a through opening configured to receive one or more cables, wherein the at least one compressible module is positioned between the support bracket and the back piece; and the locking device is configured to lock the end piece of the support bracket to the back piece and compress the at least one compressible module around the one or more cables. The retaining device according to the present invention provides secure, organized, and reliable holding of cables, as well as easy and efficient cable installation. The configuration of the support bracket having an end piece with a recess in cooperation with the locking device allows the user to easily compress the compressible module to hold the cables in place and lock the support bracket to the back piece by the locking device. The retaining device holds the weight of the cables and supports their load. For example, the retaining device supports the weight of one or more cables that extend at least partially vertically. For example, the retaining device supports the weight of cables below a compressible module. The retaining device can also reduce or minimize vibrations in both the axial and radial directions along the cable, and such vibrations are absorbed by the compressible module that holds the cable within the retaining device.

[0005] The locking device may be a cam lever locking device, which allows the support bracket to be quickly and easily pushed toward the back piece while simultaneously compressing the compressible module. Alternatively, the locking device may be a screw or bolt having a head for pushing the support bracket toward the back piece when tightened. Therefore, to ensure secure fastening, the locking device can be easily tightened using a tool such as a power tool.

[0006] The support bracket may have a first end piece and a second end piece, each of which has a recess, with the first end piece having a first recess and the second end piece having a second recess. The end pieces may be located at both ends of the support bracket and may extend radially outward, and the cable(s) passing through the compressible module may extend axially, for example, vertically. For example, the end piece may be a plate or plate portion extending in the vertical plane, with the recess extending upward from the lower edge and accessible from the bottom to receive a locking device. The retaining device may also include a first locking device connected to a back piece and cooperating with the first end piece of the support bracket via the first recess, and a second locking device connected to the back piece and cooperating with the second end piece of the support bracket via the second recess to push the support bracket toward the back piece, compressing the compressible module while locking the support bracket to the back piece. Therefore, the retaining device may include two locking devices. For example, one locking device is fastened to the back piece, and a support bracket can slide from above on the locking device so that the locking device is received in a recess. The two locking devices may be screws having heads, the heads of which can be accessed by a tool for tightening them. Alternatively, at least one of the locking devices is a manually tightened cam lever locking device.

[0007] The retaining device may have an elongated opening extending between the two end pieces of the support bracket. Thus, the support bracket may be positioned to receive, for example, multiple compressible modules arranged side by side in a horizontal plane, thereby allowing the retaining device to receive multiple cables in parallel.

[0008] The support bracket may have a bottom lip configured to support a compressible module positioned between the support bracket and the back piece. Thus, the compressible module is held in place during installation and before being tightened and locked by the locking device.

[0009] The compressible module has through-openings for one or more cables and may be formed of module halves, each module half having grooves opposite to grooves in the other module half, these grooves forming the through-openings. The grooves in the module halves may be filled with peelable material layers so that the through-openings conform to the dimensions of the cables, for example, the diameter of the cables.

[0010] According to a second embodiment, a retaining system for holding one or more cables is provided. The retaining system comprises a tubular body and at least one retaining device, the tubular body comprising at least one removable panel for accessing the retaining device. The retaining system may be configured to be mounted on a surface such as a floor or rooftop, and may include a curved tubular element commonly used as a cable transit on roofs and also known as a swan neck frame or simply a swan neck. Alternatively, the retaining system may be mounted, with or without a swan neck, on a cabinet, duct, or shaft such as an elevator shaft or tunnel, or at other suitable location. For example, the retaining system is used to hold one or more cables that extend at least partially vertically. The retaining system enables efficient mounting and retention of cables. It also enables reliable and efficient cable retention for cables sent from inside a building to a rooftop. By providing cable retaining devices and systems according to the present invention, installation is simplified, for example, because it is not necessary to transfer cables to smaller, more flexible cables to connect cables to other equipment. The retaining system may include a conventional swan neck, which may be provided with a sealing module necessary for sealing around the associated cable.

[0011] The retaining system may include a plurality of retaining devices, for example, at least one first retaining device and one second retaining device, which can be displaced from each other both axially and radially. For example, the second retaining device can be displaced both vertically and horizontally relative to the first retaining device. For example, the second retaining device may be positioned below the first retaining device and closer to it by a removable panel. Thus, by first installing the first retaining device and then installing the second retaining device, the cables of the second retaining device are routed in front of and parallel to the cables of the first retaining device.

[0012] According to a third aspect, a method for holding one or more cables is provided. The method is The steps include preparing a holding system comprising a tubular body and at least one holding device disposed inside the tubular body, The steps include attaching the first end of the tubular body to the surface, The steps include placing the cable through the opening of the compressible module, The steps include placing the compressible module on which the cables are arranged into the support bracket of the retaining device, The steps include: compressing the compressible module around the cables within it by fastening the support bracket on which the compressible module is placed to the back piece of the retaining device with a locking device; The process includes the step of attaching a curved tubular element to the second end of the tubular body.

Mode for Carrying Out the Invention

[0016] As shown in FIGS. 1 to 3, a holding system 200 is shown. The holding system 200 has a tubular body 210 formed by side walls 240, 250, a front wall 260, and a rear wall 270. The walls are substantially rectangular, but may be of other shapes. Further, the walls 240, 250, 260, 270 may be removably attached to each other to form the tubular body 210, or may be integrated with each other. At the ends of the tubular body 210, a first end flange 220 and a second end flange 230 are respectively arranged. For example, the tubular body 210 is rectangular.

[0017] The end flanges 220 and 230 may be detachably attached to the tubular body 210 or integrated with the tubular body 210. The end flanges 220 and 230 resemble a frame in that each has a rectangular opening 221 corresponding to the opening of the tubular body 210. The end flanges 220 and 230 surround the outer circumference of the opening of the tubular body 210. For example, the end flanges 220 and 230 extend continuously along the outer circumference of the opening. The opening of the tubular body and the opening of the end flanges do not need to have the same dimensions. The end flanges 220 and 230 have holes 232 configured to receive fastening means 223, which can fasten the retaining system 200 to, for example, a curved tubular element 300 (shown as a dashed line in Figure 1), often called a swan neck frame or simply a swan neck, and to a building rooftop or other surface (not shown). In Figure 1, the four holes 232 without fastening means are visible in the lower end flange 230. In the upper end flange 220, the holes are covered by fastening means 223. Note that the retaining system can be fastened to a target object or target surface in various ways. For example, the fastening means 223 of the end flanges 220 and 230 may be screws, bolts, adhesives, welded joints, etc.

[0018] In FIGS. 1 to 3, the front wall 260 has an opening (opening 261 shown in FIG. 4) covered by a removable panel 262. The removable panel 262 is a location for providing access to the inside of the holding system 200. For example, the removable panel also serves to keep the inside of the removable panel away from dust, water, contaminants or other things that may adversely affect the cables within the holding system 200. For example, the removable panel 262 may be hinged to the tubular body 210. The opening in the wall is surrounded by holes (not shown) for attaching the removable panel to the wall. Fastening means 264 are provided for attaching the removable panel 262 to the wall 260. The fastening means 264 of the removable panel may be, for example, screws or other mechanical fastening elements. For example, at least one of the side walls 240, 250 has an opening covered by a removable panel that provides access to the inside of the tubular body 210. Thus, at least one of the front wall 260 and the side walls 240, 250 has a removable panel that provides access to the inside of the holding system 200.

[0019] The curved tubular element 300, i.e., the swan neck, is shown in FIGS. 1 to 3 (by the dashed lines in FIGS. 1 and 3) to illustrate the purpose of the holding system 200 that provides a transit for one or more cables to penetrate through the roof or other partitions. The swan neck 300 is a hollow element that provides a passage for a cable or pipe that passes through and is held within the tubular body 210 of the holding system 200. A space is provided in a part such as the end of the curved tubular element, configured to receive a plurality of compressible modules or the like for sealing around the cable. The holding system 200 functions as an extension between the roof of the building and the swan neck 300. As seen in FIGS. 1 to 3, the swan neck is attached to the upper end flange 220 of the holding system 200. In one embodiment, the swan neck 300 is included in the holding system.

[0020] External grounding lugs 251, for example, a first external grounding lug 251, are provided on the side walls 250 of the tubular body 210 to secure the retaining system 200 to the ground of the building.

[0021] The same retaining system 200 described in relation to Figure 1 is shown in the side view and front view of Figures 2 and 3, respectively. In Figure 3, another external grounding lug 241 is provided, such as a second external grounding lug 241 configured to secure the retaining system 200 to the ground of the building.

[0022] In Figure 4, a perspective view shows a portion of the retaining system 200 described in relation to Figures 1-3. Here, a gasket 281 is provided on the upper end flange 220. For example, the gasket 281 includes a sealing material, an expandable material, an adhesive material, and / or a conductive material. For example, the gasket 281 is a conductive gasket. For example, the gasket 281 is arranged to provide RF shielding, EMI shielding, grounding, or coupling. For example, the gasket is self-adhesive. In the illustrated embodiment, the gasket 281 is located on a self-adhesive element 280 above the end flange 220 facing a portion extending from the roof of a curved tubular element 300 or the like. Fastening means 223 pass through holes (not shown) provided in both the sealing material and the end flange 220. In practice, these fastening means 223 pass through the corresponding end flanges of the aforementioned swan neck (shown by dashed lines in Figure 1). A hole 232 is provided for attaching the lower end flange 230 to the building's roof. For example, a gasket 282 similar to the gasket 281 described above is placed between the end flange 230 and the rooftop on a self-adhesive element 280 or the like.

[0023] The interior of the tubular body 210 is exposed through an opening 261 in the front wall 260. Multiple fastening means 264 pass through holes (not shown) provided in both the front wall 260 and a gasket 283 surrounding the opening 261 in the front wall 260. As seen in Figure 4 through the opening 261 in the front wall 260, two retaining devices 100 are mounted inside the tubular body 210. In practice, one or more retaining devices 100 may be positioned simultaneously within the retaining system 200. These retaining devices 100 will be described in detail below with reference to Figures 6 and 7. The purpose of the retaining devices is to hold one or more cables passing through the retaining system 200 in place and to provide a method for facilitating cable installation and access as needed. The removable panel 262 and / or side walls 240, 250 of the front wall 260 are removable to allow easy access to the interior of the tubular body 210.

[0024] Furthermore, the internal grounding lugs 252 are attached to the inside of the side walls 250 of the tubular body 210, securing the retaining system 200 to the building's ground.

[0025] A removable mounting plate 272 is positioned on the rear wall 270 of the tubular body 210 shown in Figure 4. The mounting plate 272 is fastened via fastening means 274, of which only two are shown in Figure 4. In practice, there may be three or more fastening means 274 for holding the mounting plate 272 in place. Selectively, the rear wall 270 may not have a mounting plate 272. For example, the mounting plate 272 is positioned at a distance from the rear wall 270, as shown in Figure 10. In one embodiment, the mounting plate 272 is not electrically insulated.

[0026] In Figure 5, the same features as those described with respect to Figure 4 are shown, except that the front wall 260 and side wall 240 are removed. This is to further illustrate what the inside of the tubular body 210 looks like. As seen, the retaining device 100 is attached to the rear wall 270 via mounting brackets 290, 291. The mounting brackets 290, 291 are of different sizes to provide space for cables when attaching them to their respective retaining devices 100. In Figures 4 and 5, the mounting brackets 290, 291 are attached to the rear wall 270 and spaced apart and offset from each other along the longitudinal direction of the tubular body 210, which is the same longitudinal direction as the walls of the tubular body. Optionally, the mounting brackets are configured to be attached to the side walls 240, 250 of the tubular body 210, and the retaining device 100 is configured to be attached to the mounting brackets. The mounting brackets 290, 291 may be fixedly attached to the relevant walls or may be detachably attached. Accordingly, in the illustrated embodiment, the retaining system 200 includes a first retaining device and a second retaining device 100, wherein one retaining device is positioned below the other retaining device, and one retaining device is positioned closer to the front wall and its removable panel than the other retaining device.

[0027] Referring to Figures 6 and 7, the retaining device 100 previously shown in Figures 4 and 5 is shown in perspective views from the bottom and top, respectively. The retaining device 100 has a support bracket 110 having two end pieces 111, 112. Each of the end pieces of the support bracket 110 has corresponding recesses 113, 114, and locking devices 121, 122 move or slide over these recesses. The retaining device 100 further has a back piece 120. When installed, the support bracket 110 is pressed against the back piece 120 by the locking devices 121, 122. For example, the locking devices 121, 122 are cam lever locking devices. However, other types of locking devices can be used as well, as long as they can tighten or press the support bracket 110 against the back piece 120 and lock it in a tightened position. Alternatively, the locking devices 121, 122 may be screws or bolts for tightening the support bracket 110 to the back piece 120. For example, the support bracket 110 includes a first plate portion, the first plate portion having each end connected to a side plate portion extending perpendicularly to the first plate portion, the side plate portions being connected to end pieces 111, 112, the end pieces extending parallel to the first plate portion. Thus, the end pieces extend in a plane parallel to the plane of the first plate portion, and the side plate portions extend between the first plate portion and the end pieces 111, 112. Alternatively, the support bracket 110 includes a single end piece 111 cooperating with a single locking device 121 (which may rotate between a run-through position and a position cooperating with the end piece), the opposite end of which may be attached to the back piece 120 by a hinge (which may include a spigot that slides vertically within the casing) or similar.

[0028] The retaining device 100 is configured to hold at least one cable or pipe. This can be achieved by holding one or more compressible modules 130. Preferably, the retaining device 100 is arranged to hold multiple modules. In both Figures 6 and 7, multiple compressible modules 130 are arranged along the length of the retaining device 100. A module 130 is formed of two module halves 131, 132, each module half having a groove, for example, a semi-cylindrical groove, on one side. Multiple peelable layers 140, 141, 142, 143, etc., are arranged overlapping each other in the grooves. The peelable layers 140, 141, 142, 143, etc., are configured so that the inner diameter of the module 130 is removed to fit the outer diameter of the cable, wire, or pipe to be received in the module 130.

[0029] While the compressible module 130 is being attached to the retaining device 100, the two module halves 131 and 132 are assembled with their respective grooves facing each other. Simultaneously, the module halves 131 and 132 form a module 130 having a central through-opening 150 into which a cable or pipe is received. For example, the opening is cylindrical. Thus, when the module 130 receives a cable or pipe, several layers 140, 141, 142, 143, etc., are peeled off as necessary. Once the pipe and / or cable are respectively placed inside the module 130, the support brackets 110 and back piece 120 surrounding the module 130 together, as seen in Figures 6 and 7, are tightened by locking devices 121 and 122 so that they face each other. Tightening of the locking devices 121 and 122 compresses the compressible module 130 in one direction into the retaining device 100, but expands in the other direction between the support brackets 110 and the back piece 120. Generally speaking, the tightening of the locking devices 121 and 122 causes the module 130 to be compressed relative to the retaining device 100 and the cable, wire, or pipe. For example, the compressible module 130 is made of rubber or a compressible plastic material.

[0030] In particular, as shown in Figure 6, the support bracket 110 has a bottom lip 115 configured to hold the compressible module 130 in place. This eliminates the need for an operator or user attaching the module 130 to the support bracket 110 to worry about the module being inserted too deeply into the elongated opening of the support bracket 110 or falling out of the opening. For example, the dimensions of the bottom lip 115 are set so that cables or pipes of the maximum diameter can pass through the compressible module 130 without interfering with the bottom lip 115. For example, the bottom lip 115 extends radially, for example, in the horizontal plane. Thus, the bottom lip 115 is positioned to support the bottom of the compressible module(s) 130. For example, the bottom lip 115 extends along the inner lower end of the support bracket 110, for example, continuously along the entire inner lower end of the support bracket 110.

[0031] With reference to Figures 8 and 9, different embodiments of the curved tubular element 300, namely a swan neck, will be described. The swan neck 300 is a through-hole for one or more cables as described above. The swan neck 300 has at least one inlet opening 310 for receiving cables. The inlet opening 310 is positioned to receive a seal module, which may be similar to, for example, the compressible module 130 described above. For example, at a first end, such as the upper end, the inlet opening 310 of the swan neck 300 includes a frame 320, for example, a substantially rectangular frame, for receiving a plurality of compressible modules and compression units, such as conventional compression units of a wedge shape or similar form, and optionally includes stay plates positioned between the compressible modules or rows thereof. In the embodiment of Figure 8, the swan neck 300 has a single frame 320 for receiving cables. Alternatively, the swan neck 300 may be provided with a plurality of opening frames, for example, two, three or more frames 320. In the embodiment shown in Figure 9, the swan neck 300 includes, as described above, a first frame 320a and a second frame 320b arranged side by side for receiving a seal module on which the cable is located.

[0032] The swan neck 300 is positioned to be attached to the tubular body 210, as described above. In the illustrated embodiment, the swan neck 300 includes an end flange 330 at a second end, the second end being the lower end and facing the first end having a frame 320. The end flange 330 is positioned to be attached to the first end flange 220 of the tubular body 210, for example, by screws passing through holes 340 or by other fastening devices. Optionally, a gasket 281 is positioned between the end flange 330 of the swan neck 300 and the first end flange 220 of the tubular body 210.

[0033] The swan neck 300 is curved between the first and second ends, with the first upper end and the second lower end positioned in different planes. Thus, the swan neck 300 is curved between the end flange 330 and the frame 320. For example, the swan neck 300 is curved at least 45 degrees and at least 60 degrees, or curved at about 90 degrees such that the plane of the first end and the plane of the second end are perpendicular to each other. For example, the second bottom plane and the end flange 330 extend substantially horizontally. Cables placed within the inlet opening 310 follow the curve of the swan neck 300 as a whole, and the swan neck 300 efficiently supports the load of cables entering through the compressible module in the frame 320. The load-bearing capacity of the swan neck 300 in combination with the retaining device 100 described above has been found to provide an efficient and secure cable retaining system.

[0034] As shown in Figure 10, parts similar to the retaining system 200 described with respect to Figure 4 are shown in another embodiment. Similar numbers refer to similar elements. In Figure 10, the mounting plate 272 is attached to the rear wall 270 by at least one fastening means 274', for example, a screw or similar removable fastening means. The mounting plate 272 is positioned at a distance from the rear wall 270 by, for example, a spacer element, to form a space between the rear wall 270 and the mounting plate 272. This space is provided for, for example, receiving cables, connectors, etc.

[0035] In the embodiment of Figure 10, a screw may be used as a locking device 122' for fastening the support bracket 110 to the back piece 120 of the retaining device 100 (see Figures 6 and 7). Thus, instead of the cam lever locking devices 121, 122 shown in Figures 4-7, the locking device 122' in Figure 10 is a screw for fastening the support bracket 110 to the back piece 120 (see Figures 6 and 7). The locking device 122' may be fastened by a tool, such as a power tool, for rotating the threads of the locking device 122' into the corresponding opening in the back piece 120. For example, the locking device 122' includes a head that is locked and operated by the tool in a conventional manner, such as a conventional polygonal bolt head. For example, since the locking device 122' is accessible by the tool through the front opening 261, it can be fastened and released by the tool through the front opening 261.

[0036] In the illustrated embodiment, a removable or breakable protective section 242, such as a mesh or similar material, is positioned at the bottom of the retaining system 200 to prevent parts or debris from unintentionally falling into the retaining system 200 during installation or assembly. For example, the protective section 242 can be cut before a cable is pulled through the retaining system 200.
