BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a code insertion device which is attached to a top plate of a desk or the like to form a code insertion hole.

[0002]

2. Description of the Related Art Telephones are indispensable for desks used in offices. At that time, telephone line codes are complicated on the desks. Various desks equipped with an insertion device have been developed.

Furthermore, with the recent office automation,
OA equipment such as word processors is often placed on a desk, and thereby the power cord is wired more complicatedly, so that a desk equipped with a code insertion device is more and more demanded.

Conventionally, as a cord insertion device of this type,
There is a holder that can be opened and closed by pivotally attaching a top cover to the holding frame.However, when connecting the cords, insert the cord connector into the code insertion hole with the top cover open. Therefore, there has been a problem that the upper lid is an obstacle and the upper lid is damaged.

Also, when a code thicker than the cord insertion notch provided in the upper lid or a large number of cords are passed through the cord insertion hole, the upper lid is left open after the completion of the wiring work. However, there was a problem that it was unsightly in appearance.

On the other hand, there is a type in which the upper lid is detachable from the holding frame, but there is a problem that if the upper lid is removed at the time of code connection work, the upper lid may be left behind or lost. In view of such problems of the conventional technology, the present invention can easily carry out the wire connecting work of the cord while holding the upper lid on the holding frame, and the upper lid is not lost.
It is an object of the present invention to provide a code insertion device for a desk, which looks good even if any code is passed through the code insertion hole.

[0007]

In order to achieve the above object, the cord insertion device of the present invention is provided with a hanging portion and a cord insertion notch at one end, and is formed downward at the other end. An upper lid provided with a semi-circular curved portion, a support projection portion with which the hanging portion abuts in the closed state of the upper lid, and a rotation holding portion for rotatably holding the curved portion, and the lower surface is opened. When the upper lid is turned to a vertically opened lid state, the upper lid is movable up and down with respect to the holding frame, and the hanging portion and the rotation holding portion come into contact with each other in the lowered state. It is characterized by being configured as follows.

[0008]

When the upper lid is rotated to the vertical open state, the curved portion of the upper lid and the rotation holding portion of the holding frame are disengaged, and the upper lid can move up and down with respect to the holding frame. In the lowered state, the hanging portion of the upper lid and the rotary holding portion of the holding frame contact each other, so that the upper lid is held with respect to the holding frame.

Thus, the cord connection work can be easily performed, and after the connection work is completed, the upper cover can be easily closed by raising and rotating the upper cover. Also, when a code thicker than the code insertion notch provided on the upper lid or a large number of cords are inserted through the code insertion hole, the upper lid is lowered with respect to the holding frame, and the lower portion is rotated. By bringing the moving holding portion into contact, the upper lid is not lost, and a large code insertion hole is thereby formed.

The holding frame (2) is formed in a substantially box shape with its upper and lower surfaces opened, and the inside of the front wall (6) of the holding frame (2) has an upper lid (3).
A support projection (9) is provided for holding the closed state of the. In addition, between the rear side walls (10) of the holding frame, a circular cross section for rotatably holding the upper lid (3) with a distance C from the holding frame rear wall (11) to the same dimension as the thickness of the upper lid (3). Swivel holding part (12)
Is attached.

The upper lid (3) holds the upper surface of the holding frame (2) in a closed state. At the front end of the upper lid (3), there is a hanging portion (13) and a cord insertion notch (14). A semi-circular curved portion (15) formed downward is provided at each of the rear ends thereof. The curved portion (15) engages with the rotation holding portion (12) of the holding frame (2), whereby the upper lid (3) is rotatable.

Then, in the closed state of the upper lid (3), the upper lid (3)
When the hanging part (13) of the upper cover (3) contacts the supporting projection (9) of the holding frame (2) and the upper cover (3) is vertically opened, the bending part (15) is bent.
And the rotation holding portion (12) are disengaged, and the upper lid (3) can move up and down in parallel with the rear wall (11) of the holding frame.
(13) and the rotation holding part (12) are configured to come into contact with each other.

Therefore, the hanging portion (13) of the upper lid (3) has a function of holding both the closed state and the opened state of the upper lid. In FIG. 1, the upper lid (3) is divided into two pieces, but as shown in FIG. 4, one upper lid (3) may be used.

Next, the operation will be described. As shown in FIG. 2, in the closed state (solid line position) of the upper lid (3), the hanging portion (13)
And the supporting projection (9) are in contact with each other, and the upper lid (3) is held by the holding frame (2). Next, as shown by arrow A, when the upper lid (3) is rotated to bring it into the vertical open state shown by the two-dot diagonal line position, the curved portion (15) and the rotation holding portion (12) are disengaged. The upper lid (3) can be moved up and down in parallel with the holding frame rear wall (11) via a space C between the holding frame rear wall (11) and the rotation holding portion (12).

Then, as shown by an arrow B, the upper lid is lowered to bring the hanging portion (13) into contact with the rotation holding portion (12), and the upper lid (3)
Is held by the holding frame (2) without being separated from the holding frame (2). This state is shown in FIG. Therefore, the holding frame
