を通して外部に導出させている。By the way, in the desk of the type that raises and lowers the top plate as described above, in order to ensure a smooth raising and lowering operation of the top plate, or because of aesthetic problems, the wiring of the equipment and the power supply A cord or the like is drawn into a space below the top plate from a hole provided in the top plate, and is led to the outside from here through a hole provided in the back plate of the desk body.

くおそれがあった。However, in any of the above-described lifting mechanisms, the constituent elements such as the guide rail, the sliding member, the screw shaft, and the nut piece are exposed in the accommodating space. For this reason, when the top plate is moved up and down, wiring or the like is caught in the sliding contact portion or the threaded portion between the guide rail and the sliding member or the screw shaft and the nut piece, and the movement of the top plate is hindered. There is a risk that the wiring may be broken.

り、スペースの有効利用が図れなくなる。On the other hand, as a means for avoiding such a problem, it is considered that the guide rail and the screw shaft are housed in the side plate of the desk body. However, in order to accommodate the screw shaft and the large-sized guide rail, it is necessary to provide a relatively large storage space in the side plate, and an increase in the thickness of the side plate cannot be avoided. Therefore, the space occupied by the desk becomes large and the space cannot be effectively used.

An elevation mechanism including an output shaft of the drive source housed in the internal space of the front structure, and a driving force transmission member stretched in a loop shape on the upper wheel body and the lower wheel body, The plate is connected to a driving force transmission member located between the upper and lower wheels.

The driving force transmission member stretched in a loop shape on the upper and lower wheels also rotates forward and backward in the internal space of the stationary structure. During this forward / reverse rotation, the driving force transmission member between the upper and lower wheel bodies moves up and down. As a result, the support plate connected to the driving force transmission member between the upper and lower wheels moves up and down.

に比べて、静止構体の所要厚さがより小さくなる。When the driving force transmitting member is composed of a chain, a timing belt or a wire, the width of the internal space of the stationary structure for accommodating the driving member needs to be slightly larger than the width of the chain or the like. Therefore, the required thickness of the stationary structure is smaller than that in the case where the conventional lifting mechanism is housed.

Wiring will not be caught in the lifting mechanism when the top plate is lifted. Further, similarly to the above, the required thickness of the front structure that houses the elevating mechanism is also small, so that a device storage desk that is smaller than the conventional product can be provided.

有床面積の低減が図れる。The front body (1) described above is combined with the pair of side plates (5) (5) and the back plate (3) to form the desk body (7) and the top plate provided on the support arm (45). By mounting the top plate (9) on the support part (51),
The device storage desk shown in FIG. 1 is configured. In this desk, since the lifting mechanism (11) for the top plate (9) is housed in the internal space of the front structure (1), the wiring and power supply for the OA equipment (53), etc. arranged on the top plate (9). A cord or the like (which is drawn into the lower space from a hole (not shown) provided in the top plate (9)) is not caught in the elevating mechanism by the elevating operation of the top plate (9). In addition, the thickness of the front structure (1) is the thickness of the chain (35).
Since the width of the desk can be suppressed to be slightly larger than the width, the floor area occupied by the desk can be reduced.

美感の向上が達成できる。By the way, the front structure (1) can also be used as an elevating mechanism for supporting plates for supporting articles, for example, shelf plates and bed floor plates. That is, if the front structure (1) shown in FIG. 5 is mounted on the wall surface of the house, it is possible to move up and down the shelf plate and the like with the same configuration. In this case, since the thickness of the front structure (1) is thin as described above, the aesthetic appearance of the wall surface is not impaired even after the front structure (1) is attached. Further, if the front structure (1) is embedded in the wall surface, further improvement in aesthetics can be achieved.

り一層の美感向上を図ることも容易にできる。As described above, according to the elevating mechanism of the present invention, the thickness of the stationary structure accommodating the elevating mechanism can be made thinner than that of the conventional product. Specifically, when a chain, a timing belt or a wire is used as the driving force transmission member, the thickness can be set to be slightly larger than the width of the chain or the like. Therefore, even when the stationary structure itself is mounted on the wall surface of the house, the aesthetic appearance of the wall surface is not impaired. Further, it is possible to easily embed the stationary structure in the wall surface to further improve the aesthetic appearance.

板の下方空間に引き込まれた配線類が昇降機構に巻き込
まれることもない。従って、天板の昇降動作が安定化し
且つ配線類の断線といった不具合も生じなくなる。Further, when the elevating mechanism is stored in the internal space of the front structure of the equipment storage desk, the thickness of the front structure can be reduced, so that the desk can be used even if it has the same top plate area as the conventional product. The floor space occupied by itself can be further reduced, and the space can be effectively used. Further, since the elevating mechanism is housed in the front structure, the wirings drawn into the space below the top plate are not caught in the elevating mechanism when the top plate is moved up and down. Therefore, the ascending / descending operation of the top plate is stabilized, and problems such as disconnection of wirings do not occur.
