Description

TECHNICAL FIELD The present invention relates to a desk suitable for mounting and using so-called OA equipment.

[Prior Art] When OA equipment is placed on the top of a desk and used, it is necessary to guide the power lines and communication lines, etc., which have been launched from the floor, to the equipment, and the wiring processing Is a problem.

Conventionally, in this type of desk, a duct space is formed between the front panel and the inner panel arranged inside the desk, and a slit for wiring passage is provided at the tip of the top plate so that it can be led out from the floor or the like. The wiring is guided into the duct space, and is guided from the duct space onto the top plate through a slit for passing the wiring. And in such a thing, the inner panel is fixed to both side plates,
The outer front panel is attached and detached for wiring work.

[Problems to be Solved by the Invention] However, in the case of such a configuration, it is not normally performed using the outer front panel in a removed state because the external appearance is impaired. Therefore, even when only simple wiring is performed, there is an uneconomical situation in which the front portion must be purchased and used in a double wall structure. Further, in the case of such a configuration, when the front portions are arranged in a state of being abutted with each other, it is difficult to change or add wirings unless the desk is moved.

It should be noted that although the one that allows the inner panel to be removed has been developed, in the conventional one, a horizontal beam is installed between the lower ends of the side panels, and the lower end of the inner panel is attached to the front edge of the horizontal beam. I am trying to support it. Therefore, even if the inner panel is removed, the horizontal beam remains, which not only makes the appearance worse, but also cannot expand the lower limb space or the wagon insertion space.

The present invention aims to solve the above problems.

[Means for Achieving the Purpose] The present invention adopts the following configuration in order to achieve such an object.

That is, in the desk according to the present invention, the top plate is supported by the left and right side panels, and the leading edge portions of the both side panels are connected by the front panel, and the top plate is placed between the upper edge of the front panel and the top plate. A desk formed with slits for passing wiring, in which a pin is detachably provided near the lower end of the side panel, and a bracket is attached near the upper end of the desk. A notch formed by opening downwardly is engaged with the pin, and an upper end portion of the inner panel is fixed to the bracket with a bolt.

In this case, in order to further improve the appearance when used with the inner panel removed, it is preferable that the bracket is also detachably attached to the side panel.

As another preferable mounting structure of the inner panel, a pin is detachably provided in the vicinity of the lower end of the side panel, and a receiving portion is attached in the vicinity of the upper end of the inner panel. It is also conceivable that a notched portion provided by opening to the above is engaged with the pin, and a bent piece provided at the upper end portion of the inner panel is engaged with a receiving portion provided on the inner panel.

[Operation] According to such a configuration, the inner panel can be attached / detached according to preference, and the state in which the front portion has the double wall structure or the state in which the front panel has the single panel structure is appropriately selected. Can be used. In this case, the front panel forming the outer surface of the desk is unchanged, so that the appearance does not change.

When the inner panel is attached to the inside of the front panel, the wiring that rises from the floor is guided upward through the wiring space formed between the inner panel and the front panel and passes through the slit. Guided on the top plate. Therefore, even if there is a long extra length portion or accessory equipment in the wiring, it is possible to house them in the wiring space so that they are not exposed to the outside. Then, by removing the inner panel from the use surface side, it is possible to freely change or add wiring from the use surface side.

If you do not wire or if the wiring is simple, remove the inner panel and use the same form as a normal desk that is not for OA equipment, that is, there is only one front panel on the front part of the desk. It can also be used in the form. In this case, since the pin that supports the lower end of the inner panel can be removed, unnecessary exposed objects are eliminated and the appearance is good for the user. In addition, the pin does not touch the foot, and there is no risk of colliding with the pin even if the wagon or the like is pushed along the inner surface of the side panel. Further, if the bracket can also be removed, unnecessary exposed objects do not enter the field of view even when the user looks under the top plate, so that the appearance can be further improved.

Even when the bent piece provided on the upper end portion of the inner panel is hooked on the receiving portion provided on the side panel, the basic operation described above can be similarly achieved. In addition, according to such a configuration, it is not necessary to attach or detach the bolt when the inner panel is attached or detached.
