Description

  The present invention relates to a wiring duct provided under a top plate in a desk, and more specifically to a form of a side end (also referred to as a duct end) of the wiring duct and a support structure for the side end.

  Conventionally, a cross-section such as a tray-like cross section or a generally U-shaped cross section extending in the left-right width (length) direction of the top board to accommodate the wiring of a personal computer or the like used on the desk under the top board of the desk. What provided the wiring duct which has is known.

  There are various support forms and attachment forms under the top plate of the wiring duct, but the drawer or sleeve cabinet part under the top plate, or a desk without a sleeve wagon, for example, the top plate and its support legs In a table or a table-like desk, the wiring duct can be seen from the outside. Therefore, it is considered necessary to devise the wiring duct and its mounting manner so that the appearance is good.

  In particular, a desk in a form in which the state under the top board can be seen well from the side of the desk, for example, a square-shaped leg, a four-legged leg, a U-shaped leg, etc. If the desk is supported by a leg, the duct end of the wiring duct and its supporting structure will appear to be exposed on the side of the desk unless the form of the duct end of the wiring duct and its supporting structure are devised. In addition to the above problem, there is a problem in securing sufficient mounting strength.

For example, in the case of a wiring duct disposed under a top plate supported by a leg having a wide side opening like a square leg, the space on the inner surface side of the leg located under the top board of the square leg However, the leg is small due to the square shape, so the strength of the duct end of the wiring duct, or the cross-sectional shape of the wiring duct itself, and the support member for attaching the duct end to the inner surface of the leg, From this aspect, it is thought that special ingenuity is necessary. This point is almost the same for a leg having four legs and a leg having a large open portion when viewed from a side surface such as a U-shaped side.
However, the technology that seems to have devised such a point is not found in, for example, the prior patent documents 1 and 2.

  Therefore, the present invention provides a wiring duct support structure that can exhibit sufficient mounting strength and good appearance even when the wiring duct provided under the top plate is an inner surface of a leg with a small mounting space. This is the issue.

The configuration of the wiring duct of the present invention made for the purpose of solving the above-mentioned problems is the wiring duct of a desk having both sides in the longitudinal direction of the top plate supported by legs and having a wiring duct on the bottom surface of the top plate. The wiring duct is formed so that the outer end in the length direction is in the vicinity of the inner surface of the leg and does not reach the inner surface, and the outer end of the wiring duct is connected to the outer end and the upper inner surface of the leg. A mounting bracket that is installed obliquely is interposed between the sides, and is supported on the inner surface side of the leg.

The present invention having the above structure, it is possible to adopt a support structure of said mounting bracket which is laid diagonally and fixed to the top of the leg. The wiring duct may have a shallow tray-like cross-sectional shape, and the material of the tray may be a bent product of an iron plate or an extruded material of aluminum or synthetic resin.

In addition, the legs that support both sides of the top plate from below are formed with legs that have an opening shape that allows the space on the bottom surface of the top plate to be seen when the desk is viewed from the side, and these legs are formed from square pipes or molds. can do. Further, in the leg body, the upper horizontal frame member on which the top plate is placed on the upper surface may be formed of a member having a smaller cross section than the other frame members. Furthermore, the intermediate part of the wiring duct can be supported in a suspended form on the lower surface of the top plate.
On the other hand, the wiring duct of the desk with the intermediate leg on the top plate can be of a two-divided type via the intermediate leg, and the divided end of the wiring duct can be supported by the intermediate leg.

The present invention provides a wiring duct provided under a top plate provided with legs having a round shape or a U-shape with widely open side surfaces, the length of which is in the vicinity of the inner surface of the leg at the outer end of the duct. In order to support the outer end of the wiring duct on the inner surface side of the leg, the outer end surface of the duct and the upper surface on the inner surface side of the leg are formed. Mounting brackets are installed diagonally between them, and both ends of the brackets are fixed to the duct side end surface and the inner surface of the leg. Since the side end of the duct and the mounting bracket are not exposed from the side of the desk, the appearance is good.
