Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for closing a cord insertion opening provided on a top plate such as a desk, a table, or a work table.
[0002]
[Prior art]
As this type of conventional one, for example, there are those described in Japanese Patent Application No. 60-22819 and Japanese Patent Application No. 10-85527.
[0003]
In the desk described in Japanese Utility Model Publication No. 60-22819, an opening is formed in the rear part of the top plate in the left-right direction, and a rear top plate that complements the opening is formed in this opening, with the rear end portion at the center. It is pivotally mounted so that it can be opened and closed, and a receiver is provided at the front of the upper end of the left and right sides of the opening. When the rear top plate is closed, the lower front end of the rear top plate is The rear top plate is supported so that it is flush with the top plate.
[0004]
A flexible soft rim material is fixed to the front edge of the rear top plate, and when the opening is closed by the rear top plate, a wiring cord for an electrical device or the like placed on the top plate Alternatively, a wiring cord disposed below the rear top plate is inserted between the edge member and the rear edge of the top plate so that it can be pulled out below or above the rear top plate.
[0005]
Japanese Patent Application No. 10-85527 describes an application specification or the like in which a box-like wiring duct unit having a wiring duct formed therein is provided behind the desk, and an upper surface opening of the wiring duct unit is provided. By placing a pair of front and rear duct covers on the periphery, the upper surface opening is closed.
Soft edge material is fixed to the rear edge part of the front duct cover and the front edge part of the rear duct cover, respectively. So that wiring cords such as electrical equipment mounted on the top plate or duct cover, and wiring cords stored in the wiring duct can be pulled out from above or below the edge of the duct cover. It has become.
[0006]
[Problems to be solved by the invention]
However, the rear top plate of Japanese Utility Model Publication No. 60-22819 is supported by the desk only at the four pivot points of the rear end and the front end, and the duct cover of Japanese Patent Application No. 10-85527 is Since the peripheral part is supported by the peripheral part of the upper surface opening of the peripheral part of the wiring duct unit, when a large load is applied, such as electrical equipment is placed on the center part of the rear top plate and the duct cover, There is a risk that the rear top plate or duct cover may be deformed.
[0007]
In addition, since the rear top of the Japanese Utility Model Publication No. 60-22819 is designed to pivot on the rear end of the rear top plate, a soft edge cannot be attached to the rear edge of the rear top plate. On the other hand, the front duct portion of Japanese Patent Application No. 10-85527 is mounted at the front edge, and the rear duct cover is mounted at the rear edge portion of the upper surface opening of the wiring duct unit. Therefore, a soft edge cannot be attached to the front edge of the front duct cover and the rear edge of the rear duct cover.
[0008]
Therefore, in the above rear top plate and the duct cover, the edge material for passing the wiring cord can be attached only to either the front or the back, and therefore, from the lower space of the rear top plate or the wiring duct. When connecting the wiring cord to the top of the desk or wiring duct unit and connecting it to electrical equipment mounted on the top plate, etc., between the edge material and the rear edge of the top plate, or between the edge materials In this case, the position where the wiring cord is drawn out is limited, and the wiring cord may be concentrated at a specific location. Therefore, for example, a high-power cord such as a power cord and a weak-power cord such as a cable connecting a personal computer and its mouse are mixed between the edge material and the rear edge of the top plate, or between the edge materials, The weak electric cord may be affected by noise from the high electric cord. In addition, the low-power cord and the high-power cord are easily mixed in the space below the rear top plate and in the wiring duct.
[0009]
Furthermore, since the wiring cord extending from the electrical equipment mounted on the top plate cannot be passed between the edge member and the top plate or between the edge members in an orderly manner, the appearance is deteriorated.
[0010]
Further, the rear top plate of Japanese Utility Model Publication No. 60-22819 is troublesome to attach to and detach from the desk, and the duct cover of Japanese Patent Application No. 10-85527 is simply placed on the upper surface of the wiring duct unit. Therefore, when an external force is applied, the position may shift or come off.
[0011]
In the present invention, in view of the above-mentioned problems of the prior art, even when an electric device or the like is placed on the upper surface of the duct cover that closes the opening of the top plate, the duct cover may be bent and deformed. In addition, the wiring cords of electrical equipment etc. can be pulled out in an orderly manner from the wiring duct formed under the desk to the top of the desk (or in the opposite direction). An object of the present invention is to provide a device for closing a wiring opening in a desk or the like, which can be prevented and can be easily and reliably attached to and detached from a duct cover.
