  As shown in FIG. 10, in the state where the top plate 4 is located at the lowest position, the wiring 10 inserted into the wiring insertion space 62 is lowered along with the lowering of the wiring support portion 44 </ b> B of the top plate receiving member 40. A space that is bent and deformed so as to be bent downward, is inserted into a locking portion 70 provided in the protruding portion 47 of the wiring support portion 44B, and is surrounded by the support plate 46 and the protruding portion 47 of the wiring support portion 44B. It passes from the rear side to the front side and is connected to the lifting mechanism 6.

  As described above, according to the top plate elevating desk 1B of the second embodiment, the wiring 10 is bent and deformed in accordance with the elevation of the top plate 4, and at least one is in a state where the top plate 4 is located at the lowest position. The portion passes between the top plate 4 and the panel member 5 </ b> C so as to be above the top plate 4. Then, the wiring 10 can be bent and deformed in a restriction space where movement of the wiring 10 by bending deformation is restricted along the surface of the panel member 5 on the top plate 4 side. Specifically, the restriction space has a wiring insertion space 62 surrounded by the attachment portion 82 and the bent portion 84 of the restriction member 80 as a locking space, and is defined by a space determined by the degree of bending deformation of the wiring 10 and the like. ing. Thus, the range of movement due to the bending deformation of the wiring 10 is restricted in the restriction space above the top plate 4, so that the wiring 10 is placed above the top plate 4 with the top plate 4 positioned at the lowest position. The wiring 10 extending upward from the top plate 4 can be maintained close to the panel member 5C in a state where at least the top plate 4 is positioned at the lowest position, and the wiring 10 is connected to the user side. It can be prevented from falling down.

  As mentioned above, although the preferable form of this invention was explained in full detail, this invention is not limited to the above-mentioned embodiment, In the range of the summary of this invention described in the claim, various deformation | transformation * It can be changed.

  For example, the lifting / lowering table-equipped fixture of the present invention is not limited to a ceiling / elevating desk such as a table, but can be applied to other lifting / lowering table-equipped fixtures.

  Further, the regulating member 12 in the top plate elevating desk 1A of the first embodiment or the regulating member 80 in the top plate elevating desk 1B of the second embodiment is arranged so that the top plate 4 and the panel member match the position and movement of the wiring 10. It may be provided on the surface of the panel member 5A or the panel member 5B on the top plate 4 side so as to fit in the gap with the panel member 5B.

Further, in the top plate elevating desk 1A of the first embodiment or the top plate elevating desk 1B of the second embodiment, the locking portions may be provided separately in the left-right direction of the regulating member 12 panel member 5C. . According to such a configuration, when the wiring 10 is bent and deformed as the top plate 4 is moved up and down, the wiring 10 is locked by the locking portion at a position separated in the left-right direction in the restriction space. The range in which 10 is bent and deformed is restricted in the left-right direction, and can be smoothly bent and deformed in a stable state. Therefore, it is possible to satisfactorily prevent the wiring from falling to the user side.
However, for example, in the top plate elevating desk 1A of the first embodiment, the locking portions 16 and 75 are provided on the right side when viewed from the front side, but the locking portions provided on the protruding portion 47 of the wiring support portion 44B. Since the portion 70 is provided on the left side when viewed from the front side, the wiring 10 can be smoothly bent and deformed in a stable state.

  Further, although not shown, in the regulating member 80 of the top plate elevating desk 1B according to the second embodiment, for example, at the both ends in the left-right direction of the mounting portion 82, forward from one end (that is, the top plate). A pair of bent portions may be provided so as to face the mounting portion 82 and protrude toward the other end portion after protruding toward the fourth side), and the distal ends of the bent portions may be separated from each other. Even with such a configuration, the same function and effect as those of the top / bottom desk 1B of the second embodiment can be obtained.
