<Beam>
As shown in FIG. 4, the beam 14 is a so-called cross beam member, and has a function of securing the strength of the desk 1 by connecting the left and right legs. Further, in the connection desk 100, the duct 10 is formed by the pair of beams 14 facing each other. The beam 14 is formed to have a substantially rectangular outer shape by combining a plurality of members obtained by bending a sheet metal material. FIG. 7 shows the beam 14. As shown in FIG. 7, the beam 14 mainly includes a beam body 141 connecting the legs to each other, and a reinforcing body 142 provided inside the beam body 141 to reinforce the beam body 141. The beam body 141 is formed to have a substantially rectangular parallelepiped outer shape by bending a sheet metal material in the horizontal direction a plurality of times. Specifically, the beam body 141 includes a base wall 1411 extending in the left-right direction, and a pair of opposing upper end walls 1413 and lower end walls 1414 extending rearward from the upper end edge and the lower end edge of the base wall 1411; It has a rear end wall 1412, 1412 facing the base wall 1411 and extending from the rear end edge of the upper end wall 1413 and the lower end wall 1414 so as to approach each other. An opening 143 is formed between the rear end walls 1412 and 1412. The beam body 141 is connected to the leg at its side end.

The reinforcing body 142 is formed by bending the sheet metal material in the horizontal direction a plurality of times, and forms a substantially U-shape in which both ends are connected to the base wall 1411 in a cross sectional view. More specifically, the reinforcing body 142 includes an upper horizontal wall 1421 extending rearward from the rear surface of the base wall 1411 in parallel with the horizontal surface and a vertical wall extending downward by bending the upper horizontal wall 1421 at a right angle. 1423 and a lower horizontal wall 1422 extending forward in parallel with the horizontal plane by bending the vertical wall 1423 at a further right angle and connected to the base wall 1411. The base wall 1411 is an example of the “standing wall” in the present invention. The reinforcing body 142 is provided near the center of the base wall 1411 in the vertical direction, and extends from near the left end of the base wall 1411 to near the right end in the left and right direction. The reinforcing body 142 secures the strength of the beam 14 as a beam member. The reinforcing body 142 is also called a flange. The reinforcing body 142 is an example of the “protrusion” in the present invention.

As shown in FIG. 4, in the desk body 1 according to the present embodiment, the legs are connected to each other by two beams 14 and 14 having different lengths in the left-right direction. The two beams 14 and 14 are referred to as a beam 14 a and a beam 14 b sequentially from the right side of the desk body 1. The beam 14 b is obtained by shortening the beam 14 a in the left-right direction, and the structure of both is the same. The lengths of the beams 14a and 14b in the left-right direction correspond to the lengths of the top panel P11 and the top panel P12 in the left-right direction, respectively. However, the length in the left-right direction of the beam 14 can be changed as appropriate. The beam 14a connects the end leg 12a and the intermediate leg 13, and the beam 14b connects the intermediate leg 13 and the end leg 12b. Thus, the left side surface of the end leg 12a and the right side surface of the second vertical member 132b constituting the intermediate leg 13 are connected by the beam 14a, and the second vertical member 132b constituting the intermediate leg 13 by the beam 14b. And the right side of the end leg 12b are connected. In addition, connection of the beam 14 and a leg can use arbitrary methods. The beams 14a and 14b are connected in the front-rear direction such that the rear end surface, that is, the rear surface of the rear end wall 1412 is substantially aligned with the rear end surface of the second vertical member 132b that constitutes the intermediate leg 13. Since the position of the rear end surface of the second vertical member 132b in the front-rear direction substantially coincides with the position of the rear end surface of the top plate 11, the position of the rear end surface of the beam 14 and the rear end surface of the top plate 11 in the front-rear direction The positions are almost identical. Thus, the beam 14 is offset forward with respect to the rear end surface of the first vertical member 131 b. Further, a gap is formed between the upper end surface of the beam 14 and the lower surface of the top plate 11.

  As shown in FIG. 1, the desk body 1B has the desk body 1A symmetrical in the front-rear direction. And the connection desk 100 connects the desk body 1A and the desk body 1B.

Next, a procedure for assembling the holding structure 30 according to the present embodiment and storing the hub 200 will be described. 13A to 16B are diagrams for explaining the assembly procedure of the holder 301 according to this embodiment. In the holder 301 according to the present embodiment, as shown in FIGS. 14A-B, the tray 5 shown in FIG. After the pair of mounting members 4 and 4 are engaged with the tray 5 as shown,
As shown in FIG. 15A-B, the mounting member 4 is brought into contact with the second opening edge 511b to match the screw mounting pitch of the hub 200. Thereafter, as shown in FIG. 16A-B, the hub 200 is inserted into the tray opening 511, and the hub 200 is assembled by being attached to the mounting member 4. Then, by attaching the storage cover 302 to the holder 301, the holding structure 30 shown in FIG. 9 is assembled. The details will be described below.

First, the duct opening 101 is opened by removing the duct cover 2 corresponding to the position where the hub 200 is desired to be stored. This enables the tray 5 to be introduced into the duct 10 from the duct opening 101. FIGS. 13A-B are diagrams showing a state in which the tray 5 is stretched between the reinforcing members 142 and 142. FIG. FIG. 13A shows a top view, and FIG. 13B shows an AA cross-sectional view in the duct extending direction D2 of FIG. 13A. As shown in FIG. 13A, the posture of the tray 5 in top view is such that the first opening edges 511a and 511a of the tray opening 511 are parallel to the duct extending direction D2, and as shown in FIG. Reinforcement 142,
The tray 5 is placed between the pair of reinforcing bodies 142 and 142 so as to fit between the two 142. At this time, the lower surface of the horizontal contact portion 522 in the tray side sandwiching piece 52 abuts on the upper surface of the upper horizontal wall 1421 in the reinforcing body 142, so that the tray 5 is horizontally stretched between the pair of reinforcing bodies 142 and 142. It becomes.

  Further, the outer surface of the vertical contact portion 521 abuts on the vertical wall 1423, so that the tray 5 is held between the pair of reinforcing bodies 142 in the duct width direction D1. Thus, the movement of the tray 5 in the duct width direction D1 is restricted. As a result, the installation state of the tray 5 is maintained, and the falling off of the tray 5 from the reinforcing body 142 is suppressed. Further, in this state, the tray 5 can be slid to any position in the duct extending direction D2. Thus, the holding structure 30 can be assembled at an arbitrary position in the duct extension direction D2.

Next, the pair of mounting members 4, 4 are engaged with the tray 5. 14A-B are diagrams showing an operation of engaging the pair of attachment members 4 and 4 with the tray 5, and FIG. 14A shows a top view and FIG.
4B shows an AA cross sectional view in the duct extension direction D2 of FIG. 14A. As shown in FIG. 14A, the engagement between the mounting member 4 and the tray 5 is achieved by the tray side engaging portion 51A of the tray 5 in the pair of slits 411 formed in the mounting member side engaging portion 41 of the mounting member 4 It is done by being inserted. First, the mounting member 4 is placed inside the tray opening 511 by setting the mounting member 4 on the mounting member side engaging portion 41 in an inclined state with respect to the duct width direction D1. In this state, the mounting member 4 is rotated in the horizontal plane so that the mounting member side engaging portion 41 is parallel to the duct width direction D1, and the tray 5 is provided in the pair of slits 411 and 411 as shown in FIG. 14B. The tray side engaging portions 51A, 51A are inserted. At this time, as shown in FIG. 14A, the mounting member 4, so that the mounting member side engaging portions 41, 41 of the pair of mounting members 4, 4 face each other.
Rotate 4 That is, in the top view, the pair of mounting members 4 has a posture in which the cover mounting area 42B is positioned outside the mount portion 431. As shown in FIG. 14B, when the tray side engaging portion 51A of the tray 5 is inserted into the slit 411, the upper horizontal inner wall 411a of the slit 411 abuts on the upper surface of the tray side engaging portion 51A. The inner wall 411 c is in contact with the second opening edge 511 b forming the tray opening 511. Thus, the mounting member 4 and the tray 5 are engaged. In this state, the vertical inner wall 411c of the slit 411 abuts on the second opening edge 511b of the tray opening 511, whereby the movement of the mounting member 4 in the duct width direction D1 is restricted.

  Here, in the holding structure 30 according to the present embodiment, the lower surface of the horizontal contact portion 522 of the tray 5 and the attachment member side in a state where the upper horizontal inner wall 411a of the slit 411 is in contact with the upper surface of the tray side engaging portion 51A. The distance from the upper surface of the holding piece 42 is designed to be slightly longer than the thickness t of the protrusion. Thus, when the tray side engaging portion 51A of the tray 5 is inserted into the slit 411 and the mounting member 4 and the tray 5 are engaged, the upper surface of the clamping area 42A in the mounting member side clamping piece 42 is a reinforcement It abuts on the lower surface of the lower horizontal wall 1422. As a result, as shown in FIG. 14B, the reinforcing body 142 is held vertically by the tray side holding pieces 52, 52 of the tray 5 and the mounting member side holding pieces 42, 42 of the mounting member 4.

  When the mounting member 4 and the tray 5 are engaged, in the tray 5, the upper horizontal wall 1421 of the reinforcing body 142 is in contact with the lower surface of the horizontal contact portion 522, and the mounting member is in contact with the upper surface of the tray side engaging portion 51A. When the upper horizontal inner wall 411a of 4 abuts, the movement of the tray 5 in the vertical direction is restricted. Further, in the mounting member 4, the tray side engaging portion 51A of the tray 5 is in contact with the upper horizontal inner wall 411a, and the lower horizontal wall 1422 of the reinforcing body 142 is in contact with the upper surface of the clamping area 42A in the mounting member side clamping piece 42. By contacting, the vertical movement of the mounting member 4 is restricted.

Next, the mounting members 4, 4 are brought into contact with the second opening edge 511b. 15A-B are diagrams showing an operation of bringing the pair of attachment members 4 and 4 into contact with the second opening edge 511b, FIG. 15A shows a top view, and FIG. 15B is a duct extending direction D2 of FIG. 7A shows a cross-sectional view along the line AA in FIG. Figure 1
As shown in FIG. 5A, in a state where the mounting members 4 are engaged with the tray 5, the pair of mounting members 4, 4 are slid in the tray opening 511 so as to be separated from each other in the duct extension direction D2. The mounting member side engaging portion 41 is in contact with the pair of second opening edges 511b and 511b. Thereby, the pair of attachment members 4 and 4 are in a state in which the attachment member side engaging portion 41 is in contact with the second opening edge 511b. As a result, in a top view, the cover attachment area 42B of the attachment member 4 is positioned outside the tray opening 511. As described above, the distance between the second opening edges 511b and 511b of the tray opening 511 is designed to be slightly longer than the total dimension of the first hub length L1 and the plate thickness of the mounting member 4 Therefore, the hub 200 can be inserted through the tray opening 511 by the attachment member 4 abutting on the second opening edge 511b.

Next, with the hub 200 inserted through the tray opening 511, the hub 200 is attached to the mounting member 4. 16A-B is a view showing an operation of attaching the hub 200 to the mounting member 4, and FIG. 16A shows a top view, and FIG. 16B is an AA in the duct extending direction D2 of FIG. 16A.
A cross sectional view is shown. As shown in FIG. 16A, the hub 200 is inserted through the tray opening 511 such that the upper surface is on top and the width direction matches the duct width direction D1. As described above, since the distance between the second opening edges 511b and 511b of the tray opening 511 is designed to be smaller than the second hub length L2, the mounting pieces M2 projecting from the hub 200 are a pair of mounting members 4 , 4 are mounted on the hub connection pieces 43. Thus, the hub 200 is stretched between the mounting members 4 and 4. Then, the hub mounting screw hole 432 of the mounting portion 431 and the mounting hole M3 of the mounting piece M2 are aligned with respect to each of the pair of mounting members 4 and 4, and a screw member not shown is The mounting piece M2 is connected to the mounting portion 431 by screwing. Thus, the hub 200 is attached to the attachment member 4. As described above, the holder 301 is assembled, and the hub 200 is held by the holder 301. As described above, in the holding structure 30 according to this embodiment, the hub mounting screw hole can be changed so that the number of the hubs 200 attached to the mounting member 4 and the storage position of the hub 200 in the duct width direction D1 can be changed. The number and pitch of 432 are designed. In the present embodiment, as shown in FIGS. 16A-B, two hubs 200 are accommodated as an example.

  Here, FIG. 17 is a cross-sectional view taken along the line BB in the duct width direction D1 of FIG. 16A. As shown in FIG. 17, in the state where the hub 200 is held by the holder 301, the mounting member 4 is in the second opening edge 511 b of the tray 5 and the hub 200 inserted through the tray opening 511 in the duct extension direction D2. It is in the state of being caught. Thus, in the state where the hub 200 is held by the holder 301, the attachment member 4 is restricted from moving further inside the tray opening 511. That is, the movement of the mounting member 4 in the tray opening 511 is restricted by the mounting member 4 being sandwiched between the second opening edge 511b of the tray 5 and the hub 200 in the duct extension direction D2. As a result, the engagement between the mounting member 4 and the tray 5 is maintained, and the mounting member 4 is prevented from falling off the tray 5.

  As described above, when the hub 200 is held by the holder 301, the movement of the tray 5 in the duct width direction D1 is restricted by the reinforcing body 142, and the movement in the vertical direction is restricted by the reinforcing body 142 and the attachment member 4. It is done. Further, the movement of the mounting member 4 in the duct width direction D 1 is restricted by the tray 5, and the movement in the duct extension direction D 2 in the tray opening 511 is restricted by the tray 5 and the hub 200. Thereby, the tray 5 is prevented from falling off the reinforcing body 142 and the mounting member 4 is prevented from falling off the tray 5, and the holding of the hub 200 by the holder 301 is maintained.

  Further, since the holder 301 is assembled to the reinforcing body 142 so as to sandwich the reinforcing body 142 from above and below, the holder 301 can be slid in the duct extending direction D2 while holding the hub 200. As a result, the hub 200 can be accommodated at an arbitrary position in the duct 10.

Furthermore, the holding structure 30 according to the present embodiment can protect the hub 200 from an external impact and improve the design of the connection desk 100 by providing the storage cover 302. As shown in FIG. 9, the storage cover 302 is attached to the holder 301 by connecting the pair of attachment members 4 and 4 to each other of the pair of cover members 7 and 7. Specifically, each of the pair of upper plates 73, 73 of the cover member 7 is connected to each of the pair of attachment members 4, 4. That is, by connecting one upper plate 73 of the cover member 7 to one mounting member 4 and connecting the other upper plate 73 to the other mounting member 4, the cover member 7 is attached to the holder 301. The connection of the upper plate 73 to the mounting member 4 is performed by aligning the cover mounting screw hole 731 of the upper plate 73 with the cover mounting hole 421 provided in the mounting member side clamping piece 42 of the mounting member 4. This is done by screwing the cover mounting screw hole 731. By attaching the cover member 7 to the attachment member 4, the cover plate 71 covers the side surface of the hub 200. The holding structure 30 can cover both side surfaces of the hub 200 by attaching the pair of cover members 7 to the mounting member 4. In general, the hub 200 often does not have an appearance in which the design is considered. The holding structure 30 according to this embodiment can cover the hub 200 housed in the duct 10 with the cover member 7. As a result, when the connection desk 100 is viewed from the front and back, it is possible to make the side surface of the hub 200 less visible. As a result, the aesthetics of the connecting desk 100 can be improved.
