DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a through hole device for wiring electric wires for electric appliances through a desk top plate or the like.

[0002]

2. Description of the Related Art With the widespread use of OA devices such as word processors and personal computers, these devices are often installed on desks in offices at all times, and in general, they are installed on desks. Is also equipped with a telephone.

Electric wires for power supply and communication are attached to these devices, and the number of electric wires is increasing in accordance with the number of installed devices.

If these many electric wires are simply extended from the device on the desk to the side surface or the floor of the desk, a pedestrian or an article may be caught and shock the device.
In addition, there is an inconvenience that it becomes messy and spoils the aesthetics of the office.

For this reason, there are some so-called system desks and the like in which a through hole for inserting an electric wire is provided at an appropriate position on the top plate of the desk so that the electric wires from the respective devices are collected and guided to the outside of the desk.

Such a through hole (hereinafter referred to as a wiring through hole)
For example There is a configuration in which a through hole is formed in a top plate and a bushing made of rubber or plastics is mounted.

There is also known a through-hole device in which an instrument having a vertically penetrating hole is embedded in a top plate, and a lid is hinged on the upper end of the hole so as to be openable and closable, or a thin plate-shaped lid is provided. Some are cut off when used to form through holes.

[0008]

The means for directly forming the wiring through-holes in the top plate can be easily formed if the desk maker provides them at the time of manufacturing, but the means for installing the equipment is If the number of wiring holes increases, the number of existing wiring through holes may be insufficient.

If a large number of wiring through-holes are provided to some extent in case the number of wirings is large, there is a problem that unnecessary wiring through-holes are opened on the top plate and become unclean when there are few installed devices. is there.

It is conceivable that plugs matching the respective wiring through holes are prepared to close unused wiring through holes, but the plugs of the wiring through holes in use are prepared for later use. There are inconveniences such as having to be stored and taking time for attachment / detachment.

[0011] An instrument in which the lid is hinged so as to be openable and closable is inconvenient because the lid protrudes from the upper surface near the through-hole when used, and the cut-off type lid is used when the through-hole is no longer used. In addition, there is a disadvantage that unnecessary through holes are opened.

It is an object of the present invention to provide a wiring through hole device which is mounted on a top plate of a desk or the like and which is provided with a lid plate which can be opened and closed in order to solve the above inconvenience.

[0013]

The present invention for achieving the above object is constituted as follows.

A main body formed in a U-shaped planar shape that fits into a notch formed in an edge of a top plate or the like of a desk is connected to both U-shaped edge edges of the main body, and a lid is provided near an upper end on an inner surface side. It consists of a cap provided with a bearing that supports the plate, and a lid plate that is pivotally supported by the bearing of the cap and that rotates to a closed position that aligns with the upper surface of the main body and an open position that hangs downward. A wiring through hole device such as a desk top plate, characterized in that locking means for locking are provided at the open position and the open position, respectively.

Locking means for locking the cover plate in the closed position is formed on the back plate of the U-shaped body, and has a protrusion at the upper end for engaging and supporting the tip of the cover plate in the closed position. It is preferable that the cover plate is formed of a locking hook that elastically displaces to release the engagement between the protrusion and the cover plate when the cover plate rotates downward.

Locking means for locking the lid plate in the open position is locked in the locking groove extending horizontally from the bearing hole of the cap and carved, and the tip of the elastic plate protruding from the lid plate. It is desirable that the pin is provided with a hitting arm that is inserted into and engages with the locking pin when the cover plate is in the open position.

[0017]

[Function] When the lid plate is in the horizontal closed position, the lid plate forms the same plane as the desk top plate to close the wiring through hole, and when it is in the hanging open position, the back plate and the cap of the main body Between,
A wiring through hole corresponding to the area of the cover plate is formed.

Locking means are provided at the closed position and the open position, respectively, to stably hold the lid plate at the respective positions.

After being attached to the top plate (7), it is preferable to attach the edge material (8) so as to cover the bracket (13).

By opening the three lid plates (3) to (5) according to the thickness and the number of electric wires to be inserted, the required wiring through holes can be formed. In FIG. 7, one lid plate (5)
Is opened and the electric wire (W) is inserted.

The remaining two lid plates (3) and (4) are held in the horizontal closed position and form substantially the same plane as the top plate (7).

That is, the wiring through hole device of the present invention forms a wiring through hole of a required size in accordance with the thickness and the number of electric wires to be inserted, and in the remaining area, the through hole is closed by the cover plate. It is possible to improve the appearance of the unnecessary through holes that are left open.

In the above description, the wiring through-hole device of the present invention is installed on the desk top plate, but the present invention is not limited to the desk top plate, and may be, for example, a shelf plate of a system rack for a personal computer. Needless to say, the same kind of equipment can be applied.

Further, the present invention is not limited to the construction of the illustrated embodiment, and for example, the number and size of the cover plates can be arbitrarily selected according to a desired wiring through hole. is there.

[0061]

【The invention's effect】

(a) A wiring through hole device for inserting an electric wire into a top plate of a desk or the like has a lid plate pivotally attached to a horizontal closed position which is substantially flush with the top surface of the top plate and a downwardly opened open position. Then, by closing the lid plate, it is possible to improve the appearance of the unused through holes remaining open.

(B) Since the lid plate is stably locked at the closed position and the open position, the lid plate should not move and become an obstacle especially when the wire is inserted at the open position. There is no.

(C) The wiring through hole can be formed to have an arbitrary size based on the size of the cover plate, and the electric wire can be easily inserted therethrough.

(D) Since the lower surface of the through hole is open, there is no risk that dust or foreign matter will collect inside the through hole and cause a failure in the inserted wire.
