[0003] [Patent Document 1] Patent No. 6712853 (page 8, figure 5) Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the wiring structure described in Patent Document 1, since it is necessary to perform processing to form a notch on the side of one of the connecting rods, there is a problem in terms of the reusability of the connecting rods. In addition, since the connection between the connecting rods is limited to the part where the notch is formed, there is also a problem in that the connecting rods cannot be connected to each other at any position.

[0005] To solve such problems, the present invention aims to provide a wiring layout structure that enables wiring at the connection parts between beams to be arranged in an attractive manner without the need for special processing for wiring on the beams. [Means for solving the problem]

[0006] In order to solve the above problems, the wiring arrangement structure of the present invention comprises: A wiring arrangement structure for a connecting portion in which a first beam having a recess at an upper portion and a second beam are connected in a T-shape in a plan view, The wiring management member provided at the connecting portion is characterized in that it has a pair of standing portions that stand up apart from each other in the longitudinal direction of the first beam in the wiring management path at the upper part of the connecting portion, and a power cord, etc., is housed and wired between the pair of standing portions. According to this feature, without the need for special processing for wiring on the first beam, etc., a power cord, etc. can be housed between a pair of upright portions at the upper part of the connection between the first beam and the second beam without being exposed, allowing the wiring at the connection part to be routed in a good-looking manner.

[0007] A hanging piece that fits into the recess of the second beam is connected to one end of the pair of upright portions. According to this feature, the power cord or the like is wired while being guided by the hanging piece, so that the power cord or the like is prevented from being damaged when the wiring is routed.

[0008] The pair of upright portions are characterized in that they widen in a V-shape in a plan view toward the first beam direction. According to this feature, the power cord, etc. can be gently bent along the standing portion which opens out in a V-shape when viewed in a plane and wired inside the recess of the first beam, making it easier to handle the wiring and preventing damage to the power cord, etc.

[0009] The other ends of the pair of upright portions, which open outwardly in a V-shape when viewed in a plane, are connected to outward pieces extending in opposite directions within the recess of the first beam. According to this feature, the power cord and the like can be guided by the upright portion that expands in a V-shape when viewed in a plane and the outward piece that is continuous with it, allowing the power cord and the like to be wired easily and without damaging the recess in the first beam.

[0010] The wiring arrangement member is characterized in that it is provided integrally with a connecting member that connects the first beam and the second beam. According to this feature, the wiring management member will not come off the connecting portion, and there is no need to manufacture the wiring management member separately, so that costs can be reduced and the number of steps required to install the wiring management member can be reduced.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A wiring arrangement structure according to the present invention will be described below with reference to the accompanying drawings. EXAMPLES

[0013] A wiring arrangement structure according to an embodiment will be described with reference to Fig. 1 to Fig. 6. Fig. 1 is a front perspective view of a partition device (spatial structure) to which the present invention is applied, which is installed on a floor surface to divide a large indoor space such as an office into sections of a predetermined size.

[0014] The partition device 1 comprises a frame body 2 that is installed independently on the floor surface. The frame body 2 comprises four support columns 3 arranged at predetermined intervals in the front-rear and left-right directions with a vertical dimension lower than the ceiling surface, and a frame 4 that connects the upper ends of the support columns 3, 3 to each other, and two left and right second beams 6, 6 are installed later by connecting members 15 described later on the opposing surfaces of a pair of front and rear first beams 5, 5 that are parallel and spaced apart from each other in the frame 4.

[0015] As shown in Figures 3 and 4, the first beam 5 and the second beam 6 are composed of a first beam body 5A, a second beam body 6A, and cover members 7, 7. The first beam body 5A and the second beam body 6A are formed of steel square tubes of the same cross-sectional shape with a vertically long rectangular hollow hole, and cover members 7, 7, which are exterior members, are attached to both longitudinal side surfaces of the first beam body 5A and the second beam body 6A. Specifically, the cover members 7, 7 are attached as follows. A plurality of fixtures 8 with an upward U-shaped cross section whose width is larger than the width of the first beam body 5A and the second beam body 6A are screwed to the upper surfaces of the first beam body 5A and the second beam body 6A, and the upper parts of the holders 9, 9 whose width is approximately the same as that of the fixtures 8 are fixed to both lower side surfaces of the first beam body 5A and the second beam body 6A below each fixture 8.

[0016] To attach the cover member 7 to the first and second beam bodies 5A and 6A, the upward U-shaped bent portion 7a formed inward at the lower end of the cover member 7 is fitted from below into the lower end of the holder 9, and then the inward piece 7b formed at the upper end of the cover member 7 is abutted against the upper surface of the inward piece of the fixing device 8 and fixed from above with a screw 10. As a result, the cover members 7, 7 are attached so as to protrude upward and downward from the first and second beam bodies 5A, 6A, and recesses 11, 11 that are continuous in the length direction and open upward are formed on the upper surfaces of the first and second beam bodies 5A, 6A. The upward-opening recess 11 of the first beam 5 has both side surfaces defined by the cover members 7, 7 and a bottom surface defined by the upper surface of the first beam body 5A.

[0017] As shown in Fig. 3, a guide rail 12 with a downward U-shaped cross section is screwed to the underside of the first beam 5. A guide roller (not shown) at the upper end of the movable partition 13 shown in Fig. 1 is supported by the guide rail 12 so as to be movable in the left-right direction, and a large-diameter wheel 14 attached to the center of the lower end runs on the floor surface, allowing the movable partition 13 to move in the left-right direction along the first beam 5.

[0018] Next, the connection structure between the first beam 5 and the second beam will be described. First, the connection member 15 connecting the first beam 5 and the second beam will be described. As shown in Fig. 5 and Fig. 6, the connection member 15 includes a rearward U-shaped connection portion 151 connected to the second beam 6, a pair of standing pieces 152, 152 standing apart in the left-right direction from the upper edge of the front plate 151a of the connection portion 151, crossover parts 153, 153 which are connected to the upper edges of the standing pieces 152 so as to extend in opposite directions, and which are U-shaped and facing downward in a side view and straddle the cover member 7 on the rear side of the first beam 5, and a pair of left and right L-shaped fixing parts 154, 154 which hang down from the outer edges of the crossover parts 153, 153 so as to be largely separated in the length direction (left-right direction) of the first beam 5.

[0019] A pair of left and right fitting pieces 151b, 151b that fit snugly into the hollow hole of the second beam 6 are provided facing rearward on both side edges of the front plate 151a of the connecting portion 151. The opposing edges of the bridge portions 153, 153 are cut out in a V-shape in plan view so as to widen toward the first beam 5, and a pair of left and right wiring management members 16, 16 are fixed to the cut-out opposing edges by welding or the like so as to be spaced apart from each other in the length direction of the first beam 5 (see FIG. 2).

[0020] The left and right wiring management members 16, 16 have standing portions 161, 161 rising from the opposing edges of the crossing portions 153, 153 at a distance from each other in the length direction of the first beam 5, outward pieces 162, 162 extending in opposite directions from the rear edges of both standing portions 161, and hanging pieces 163, 163 hanging down from the front edges of both standing portions 161 to near the upper end of the connecting portion 151. The standing portions 161, 161 are formed in a V-shape in plan view so as to expand in the direction of the first beam 5. The hanging pieces 163, 163 are formed to a length that fits into the recess 11 of the second beam 6 when the connecting portion 151 is connected to the second beam 6 (see FIG. 3).

[0021] Next, a procedure for connecting the second beam 6 to the first beam 5 will be described. First, the pair of fitting pieces 151b, 151b of the connecting member 15 are fitted snugly into the hollow hole of the second beam 6 from the front end thereof, as shown in Fig. 2, Fig. 3 and Fig. 5.

[0022] Next, the front plate 151a of the connecting portion 151 is brought close to or into contact with the cover member 7 on the rear side of the first beam 5, and the left and right fixing portions 154, 154 are inserted into the recess 11 of the first beam 5 so that the bridge portions 153, 153 straddle the rear side cover member 7, and the outward fixing pieces 154a, 154a at the lower ends of both fixing portions are fixed to the upper surface near the rear of the first beam main body 5A by the screws 17. This makes it possible to easily connect the second beam 6 to the existing first beam 5 via the connecting member 15 in a retrofit manner so as to form a T-shape in plan view. Although not shown in the figure, the rear end of the second beam 6 and the front and rear ends of the right second beam 6 can also be connected using the same connecting member 15.

[0023] In addition, the upper part of the connection between the first beam 5 and the second beam 6, i.e., the upper part of the connecting member 15, serves as a wiring route for wiring a power cord C connected to a lighting fixture S (see Figure 1) etc. attached to the second beam 6 to the first beam 5 side, and the upright parts 155a, 155a of the wiring route members 16, 16 are arranged on this wiring route.

[0024] Next, the wiring structure of the connection part between the first beam 5 and the second beam 6 will be described. As shown in Fig. 2 and Fig. 3, in order to wire the power cord C connected to the lighting fixture S attached to the second beam 6 from the second beam 6 side to the first beam 5 side, the power cord C accommodated in the recess 11 of the second beam 6 is accommodated between the hanging pieces 163, 163 and between the standing parts 161, 161 of the wiring management members 16, 16, and wired in the recess 11 on the first beam 5 side. At this time, the power cord C is guided by the pair of hanging pieces 163, 163, and also by the pair of standing parts 161, 161 that expand in a V-shape and one (or both) outward pieces 162 that are continuous therewith, and wired in the recess 11 of the first beam 5.

[0025] By wiring in this manner, the power cord C can be easily routed between the first and second beams 5, 6 and can be wired in a good appearance without exposing the power cord C. In addition, the power cord C can be wired by gently bending it along the pair of standing portions 161, 161 that open out in a V-shape, so that the power cord C is prevented from being damaged when wiring. Note that the power cord connected to the lighting fixture S or the like can be inserted into the hollow hole of the second beam 6 and pulled out from the opening 18 formed in the upper surface of the front end portion to be handed over to the wiring management member 155 (see FIG. 3).

[0026] As described above, in the wiring layout structure according to the embodiment, the power cord C is housed without being exposed between the pair of upright portions 161, 161 at the upper portion of the connection portion between the first beam 5 and the second beam 6 without any special processing for wiring layout on the first beam 5, and the wiring layout of the connection portion can be performed with a good appearance. Moreover, since no processing is applied to the first beam 5, the second beam 6 can be connected to any position of the first beam 5.

[0027] In addition, hanging pieces 163, 163 that fit into the recess 11 of the second beam 6 are connected to the front edges of the pair of upright portions 161, 161, and the power cord C is guided by both hanging pieces 163 and wired, thereby preventing the power cord C from being damaged when handling the wire.

[0028] Furthermore, the pair of standing portions 161, 161 are opened in a V-shape in a plan view toward the first beam 5, and the power cord C can be gently bent along these standing portions 161 and wired within the recess 11 of the first beam 5, making it easier to handle the wiring and preventing the power cord C from being damaged.

[0029] Furthermore, outward pieces 162, 162 extending in opposite directions within the recess 11 of the first beam 5 are connected to the rear edges of the pair of standing portions 161, 161 which expand in a V-shape when viewed in a plane, so that the power cord C can be guided by the standing portion 161 which expands in a V-shape when viewed in a plane and the outward piece 162 which is continuous with it, allowing the power cord C to be wired easily and without damaging it within the recess 11 of the first beam 5.

[0030] Furthermore, since the wiring management member 16 is integrally formed with the connecting member 15 that connects the first beam 5 and the second beam 6, it will not come off, and there is no need to manufacture the wiring management member 16 separately, which reduces costs and reduces the labor required to install the wiring management member 16.

[0031] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention also includes modifications and additions that do not deviate from the gist of the present invention.

[0032] For example, in the above embodiment, the pair of wiring management members 16, 16 are integrally provided with the connecting member 15, but as shown in Figs. 7 and 8, a pair of wiring management members 16, 16 having the same shape as in the above embodiment may be formed separately from the connecting member 15, and the upright portions 161, 161 of the separate wiring management members 16, 16 may be mounted on the upper surfaces of the opposing ends of the pair of bridging portions 153, 153 of the connecting member 15 and attached to the connecting member 15. In this case, the wiring management members 16, 16 may be bonded to the connecting member 15 so as not to move laterally, or a slit or the like may be formed in the bridging portions 153, 153 so that the lower ends of the upright portions 161, 161 are fitted therein. Also, the rear edges of the lower parts of the hanging pieces 163, 163 may be connected to each other by a connecting member so that the wiring management members 16, 16 do not move relative to each other in the laterally direction. In this way, by attaching the separate wiring management members 16, 16 to the connecting member 15, the wiring management members 16, 16 are attached to the connecting member 15 only when wiring is required, and when wiring is not required, the wiring management member 16 can be removed from the connecting member 15.

[0033] In addition, in the above embodiment, the wiring management members 16, 16 are integrally provided with the connecting member 15, but it is also possible to attach at least a pair of upright portions 161, 161 of the wiring management member 16 via a bracket or the like to the wiring path at the upper part of the connecting portion of the first and second beams 5, 6, such as the upper surface of the end of the second beam 5 or the upper surface of the rear cover member 7.
