Mounting holes 121 that penetrate the lower body 120 in the front-rear direction are formed at both left and right ends of the upper portion of the lower body 120. A lock member 122 is mounted in the mounting hole 121. The lock member 122 includes, for example, a housing 123 held in the mounting hole 121, an operation unit 124 exposed on the front surface of the housing 123 and vertically slidable, and a housing 123 linked to a sliding operation of the operation unit 124. And a claw portion 125 that can move up and down with respect to the upper surface of the.

The claw portion 125 is biased upward by a biasing member (not shown) provided in the housing 123. The claw portion 125 is locked in the locking hole 112 described above through a through hole 131 formed in an upper continuous portion 130 that is continuous from the upper end of the lower body portion 120 to the rear side of the lower plate 97. Although the lock member 122 according to the present embodiment has been described with respect to the configuration in which the lock member 122 is attached to and detached from the locking portion 102 in accordance with a sliding operation, the locking member 122 is not limited to this configuration, and the locking member 102 can be coupled with the locking portion 102 in response to a rotating operation, for example. It does not matter if they are attached or detached.

As shown in FIG. 6, in the lower plate 97, a rising wall portion 141 extends upward at the rear end of the lower continuous portion 140 that extends rearward from the lower end of the lower body portion 120. In the lower plate 97, a fixed wall 142 extends rearward at the upper end of the rising wall 141. The fixed wall 142 is superposed on the upper surface of the front bottom wall 88b described above when the lower plate 97 is mounted (the working opening 99 is closed). In the fixed wall 142, a second fixed hole 143 that penetrates the fixed wall 142 in the vertical direction is formed at a position overlapping the first fixed hole 92 in a plan view seen from the vertical direction.

On the upper surface of the fixed wall 142, a nut 145 is fixed at the same position in the left-right direction as the second fixing hole 143. The fixed wall 142 and the front bottom wall 88b are fastened in the vertical direction by a screw 146 inserted into the first fixed hole 92 and the second fixed hole 143 from below to be screwed above the fixed wall 142. .. In the example of FIG. 5, the head of the screw 146 is housed in the space surrounded by the rising wall portions 88c and 141, the fixed wall 142, and the front bottom wall 88b. Therefore, the head of the screw 146 does not protrude downward from the lower continuous portion 140 and the lower surface of the rear bottom wall 88a.

Next, in the above-described table system 1, the assembling work of the front and rear partitioning parts 21 will be described.
First, the lower plate 97 is removed to open the work opening 99. Specifically, the screw 146 is unscrewed to release the fastening between the front bottom wall 88b and the fixed wall 142. After that, the operating portion 124 of the lock member 122 is slid to release the engagement between the claw portion 125 and the engagement portion 102. In this state, the lower plate 97 is supported from below by the front bottom wall 88b via the fixed wall 142. Therefore, by gripping the upper portion of the lower side plate 97 and moving it to the front side, the lower side plate 97 rotates about the contact portions of the front side bottom wall 88b and the fixed wall 142 as fulcrums. As a result, the lower plate 97 is removed, and the work opening 99 is opened.

Next, the support tool 25 is attached to the lower surface of the top plate 12 through the work opening 99. Specifically, with the second connecting portion 45 in contact with the lower surface of the top plate 12, the second screw 55 is screwed into the embedded nut 54 through the second insertion hole 52.

Then, the pipe 24 is fixed to the top plate 12. In the present embodiment, the pipe 24 is assembled to the top plate 12 in a unitized state with at least the first curtain plate 26 (hereinafter, may be referred to as “panel”). Specifically, first, each pipe 24 of the panel is inserted into each through hole 31 of the top plate 12 from above. After that, the first screw 51 is screwed into the female screw portion 41 of the pipe 24 through the first insertion hole 48 formed in the first connecting portion 44 of the support 25. As a result, the pipe 24 and the first connecting portion 44 are fastened in the vertical direction by the first screw 51. After that, the lighting device 27 is attached to the first curtain plate 26, whereby the assembling work of the front and rear partition portions 21 is completed. The panel may be in a state in which the illumination device 27 is attached to the first curtain plate 26 in advance.

Next, the work of routing the illumination wiring 28 and the adapter wiring 16 will be described.
The illumination wiring 28 drawn out from the illumination device 27 enters the first curtain plate 26 through the communication hole 57, and then is routed through the pipe 24 to below the top plate 12. The illumination wiring 28 routed down to below the top plate 12 is drawn out of the pipe 24 through the wiring passage port 42. The illumination wiring 28 drawn out of the pipe 24 is routed downward in the storage box 72, drawn out of the storage box 72 through each bottom wall passage hole 89, and then connected to a power source (not shown).
On the other hand, the adapter wiring 16 connected to the wiring connection member 15 enters the storage box 72 through the rear wall passage hole 85 and the front wall passage hole 110. The adapter wiring 16 that has entered the storage box 72 is routed downward in the storage box 72, drawn out of the storage box 72 through each bottom wall passage hole 89, and then connected to a power source (not shown).

After the above-mentioned various operations are completed, the lower plate 97 is attached and the operation opening 99 is closed. Specifically, in a state where the fixed wall 142 of the lower plate 97 is hooked on the front bottom wall 88b from above, the lower plate 97 is rotated upward with the contact portion between the fixed wall 142 and the front bottom wall 88b as a fulcrum. .. Subsequently, after the claw portion 125 of the lock member 122 is locked to the locking portion 102, the fixed wall 142 and the front bottom wall 88b are fastened by the screw 146.
As a result, the work opening 99 is closed. The work performed through the work opening 99 is not limited to the work of assembling the front and rear partition portions 21 and the work of laying out the wiring, but can be used for other various maintenance work.

In the present embodiment, the pipe 24 is fixed to the top plate 12 via the support tool 25, and the lid portion 34 of the pipe 24 and the first connection portion 44 of the support tool 25 are fastened by the first screw 51 in the vertical direction. It is configured to be.
According to this configuration, since the pipe 24 can be fixed to the top plate 12 only on the lower surface side of the top plate 12, unlike the conventional configuration in which the top plate is sandwiched by the nuts screwed to the pipe, Nuts are not exposed on the upper surface. Thereby, the designability on the top plate 12 can be improved. Further, since the pipe 24 can be fixed to the top plate 12 only on the lower surface side of the top plate 12, even when the pipe 24 is assembled to the top plate 12 as a panel, the nut cannot be screwed from above the top plate 12. The pipe 24 can be easily assembled to the top plate 12. Thereby, the assembling property can be improved.
Moreover, in the present embodiment, since the pipe 24 and the support tool 25 are fastened in the vertical direction by the first screw 51, the deformation of the pipe can be suppressed as compared with the case where the pipe is fastened in the radial direction of the pipe, for example. Therefore, when the pipe 24 is attached to or detached from the top plate 12, interference between the pipe 24 and the top plate 12 due to deformation of the pipe 24 is suppressed, and the pipe 24 can be smoothly inserted into the through hole 31. Further, it is possible to suppress a decrease in the fastening force due to the deformation of the pipe 24 and maintain the assembled state of the pipe 24 and the top plate 12 in a good condition for a long period of time.

In the present embodiment, the wiring passage port 42 is configured to open in the radial direction of the tubular portion 33.
According to this configuration, when the pipe 24 and the first connecting portion 44 are fastened in the vertical direction, the diameter of the tubular portion 33 can be reduced as compared with, for example, the case where the wiring passage port is opened in the axial direction of the tubular portion 33. Therefore, the design of the table system 1 can be improved. Further, since the wiring passage port 42 can be secured widely, the work for drawing the illumination wiring 28 becomes easy.

In this embodiment, since the female screw portion 41 is formed on the lid portion 34 fixed to the inside of the tubular portion 33, unlike the case where the female screw portion is integrally formed on the tubular portion 33, the inner diameter of the tubular portion 33 and The size of the first screw 51 can be independently selected. Thereby, the degree of freedom in design can be improved.

In addition, the table system 1 of the present embodiment includes the above-described pipe support structure (the pipe 24 and the support tool 25), so that it is possible to provide the table system 1 that is excellent in design and assembly.
