[Conventional technology]

When guiding the electrical cords of desk lamps, telephones, office automation equipment such as word processors, etc. on the desk downward through the top plate of the desk, conventionally, an outlet attached to the tip of the electrical cord is attached to the top plate of the desk. A through hole was formed, an outlet was inserted into this hole first, an electric cord was passed through, and then this hole was closed with a rubber tongue or the like.

[Problems to be solved by the invention]

However, according to the above-described conventional guide structure for the electric cord for desks, the cord insertion hole formed on the top plate of the desk must be large enough for the outlet to pass through, and is much larger than the diameter of the electric cord. It was a thing. Therefore, there is a problem that the rubber tongue that closes the hole becomes large and the appearance of the surface of the top plate deteriorates, and the rubber tongue must be prepared as a separate component. Further, if the cord passing hole is set to have a minimum diameter in accordance with the outlet of the electric cord of the electric device on which it is placed, there is a drawback that it may be necessary to make a hole when replacing with another electric device. Further, when only the electric cord is passed with the outlet removed, the diameter of the cord insertion hole can be reduced, but there is a problem that it takes time to attach and detach the electric cord and the outlet.

The present invention has been made in view of the above circumstances, and it is possible to guide an electric cord with an outlet to the lower part of the desk through a small-diameter through hole for cords by making the holes formed on the top plate of the desk constant. An object of the present invention is to provide a guide structure for an electric cord for a desk, which does not require a separate part for closing the through hole and has an excellent appearance.

Alternatively, the number of through holes may be increased if necessary. Needless to say, the number of through holes for passing cords is not limited to three. The structure of each part shown in the above embodiment may be changed in design without departing from the gist of the present invention.

[Effect of device]

As described above, according to the present invention, a recessed hole is formed in the top plate of a desk, and an electric cord is sandwiched in the recessed hole through a cord-through partial through hole. Since a pair of cord guide blocks are fitted, an electric cord with an outlet can be guided below the top plate by a small-diameter through hole for cord passage, and a separate component that closes this through hole for cord passage. It is possible to provide a top plate that does not need to have an excellent appearance.

Further, according to the present invention, the pair of code guide blocks 3a and 3b having the split shape are substantially connected to each other by fitting the projection 13 and the hole 14 formed on the opposing surfaces thereof. Since the fitting and holding is performed by pushing the U-shaped locking member 16 from above, the fitting and holding work of the top plate 2 in the recessed hole 2a is easy and strong. Further, the locking member 16 is located in the stepped portion 2b in the recessed hole 2a of the top plate 2 and is not exposed to the outside, so that the appearance is good.

Further, in the above-mentioned fitted and held state, the bent portion 16a at the upper end of the substantially U-shaped locking member 16 is formed in the locking portions 6a and 6b of the pair of cord guide blocks 3a and 3b.
Even when the cord portion in the through hole is pulled and slides from the place where it is engaged and clamped with a and 15b, one of the pair of cord guide blocks 3a and 3b is pulled by this and slips out. There are no defects such as cracks and cracks.

Further, since the upper half of the through holes 7, 8, 9 of the cord guiding block for guiding the base of the electric cord 17 are the large-diameter counterbore parts 10, 11, 12, the electric cord 17 Has a large degree of freedom in bending, and has less fatigue of the cord. Also, since the lower half of the through holes 7, 8, 9 for passing the cord have a small diameter, the gap between the cord and the electric cord 17 is also small and the appearance is good. It is easy to use because the base part of the electric cord 17 does not move largely and is not damaged.
