【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, the present invention comprises a top plate 1 and an insertion chamber 3 for inserting and accommodating a wiring cable 2, and the computer C and its components are mounted on the top surface of the top plate. A control board Ca and a facsimile F are placed.

First, a specific structure of the insertion chamber 3 will be described.

The insertion chamber 3 is provided on the rear end surface of the top plate 1 so as to be swingable, and the frame bodies 4, 4a, 4b, 4c, 4d of the insertion chamber 3 are as shown in FIGS. The frame body is divided into a plurality of pieces in the width direction, and the length of the frame body in the longitudinal direction is long or short and various lengths. Further, openings 41 and 42 for drawing out the cable 2 are formed on the upper surfaces of some of the frame bodies 4a and 4b.

Next, a structure in which the frame body 4 of the insertion chamber 3 is swingably attached to the top plate 1 will be described with reference to the structure of the frame body 4a.

As shown in FIG. 3, in the structure of the top plate 1, a decorative plate 12 is stretched on the top surface of the top plate body 11, and the opening end surface at the rear of the top plate body is inward (see FIG. Is bent at a right angle toward the bottom), and is further bent inward parallel to the main body to form a U-shape, and the reinforcing plate 13 of the top plate 1 is fitted into the U-shape. However, a concave portion 13a is formed on the rear end surface of the reinforcing plate. Then, in the recess 13a, a mounting plate 14 for mounting the frame bodies 4 ... Is fixed by a screw 15 inserted through the opening 13b of the reinforcing plate. At the lower end of the mounting plate 14, a shaft portion 14a for hingedly connecting to the frame 4c is integrally formed in a state in which the shaft portion 14a inclines slightly downward and protrudes. As shown in FIG. 5, the outer shape is expanded into a cylindrical shape in the longitudinal direction. An inner surface-shaped bearing portion 43 is formed at the lower end of the frame body 4a so as to be removably fitted to the shaft portion 14a. Further, a locking claw portion 14b is integrally formed on the upper part of the mounting plate 14 in a state of protruding rearward, and the frame body 4a can be engaged with and disengaged from the locking claw portion. An engaging portion that engages is formed. This engaging portion is composed of the upper portion of the frame body 4a and the respective tip portions of the partition wall 44, and this partition wall is formed along the longitudinal direction of the frame body 4a as shown in FIG. In addition, a claw portion that engages with the lower surface of the locking claw portion 14b is formed at the tip of this wall.

Therefore, when the frame body 4c of the insertion chamber 3 is released from the engagement between the locking claw portion 14b and the engaging portion including the partition wall 44, the frame portion 4c is centered around the shaft portion 14a as shown in FIG. It rotates clockwise and can be opened and closed.

Further, openings 41 a and 44 a for drawing out the cable 2 are also provided in the lower surface of the frame body 4 a and the partition wall 44 so as to face the opening 41 of the upper surface.

4 and 5 show the structure of the lid 17 for opening and closing the opening 16a for inserting the cable 2, and the lid 17 is slidably attached to the rear end of the side plate 16. A fitting opening 16a is formed, and its specific structure is that guides 16b are provided on both upper and lower inner surfaces of this opening, and the upper and lower surfaces of the lid are fitted to this guide. An inner surface-shaped guide groove 17a is formed. Therefore, the lid 17 can be inserted into the opening 16a at the rear end of the side plate 16. As shown in FIG. 6, the side plate 16 has a top plate end plate 18 press-fitted and fixed in the opening ends on both sides of the top plate body 11, and the center part of the end plate is fitted. A mounting tube portion 16c protruding inward from the center of the inner surface of the side plate 16 is press-fitted into the hole.

Next, the operation of the present invention will be described.

As shown in FIG. 4, the lid 17 is fitted in the opening 16 a of the side plate 16. However, when the cable 2 is inserted from this opening, as shown in FIG. Remove the lid. After removing the lid 17, as shown in FIG. 5, the frame bodies 4, 4a, 4b, ... Of the insertion chamber 3 are opened by rotating them clockwise around the shaft portion 14a, and the cable 2 is opened. When the cable is inserted into the frame body from above the frame body, and in this case, a large hollow portion below the partition wall 44 is used, this cable is provided with the opening 44a of the partition wall 44 shown in FIG. .. and the outlet 41 attached to the end of this cable are connected to a predetermined computer C as shown in FIG. Further, a cable having a small diameter such as a telephone wire cable is pulled out from the opening 41 by utilizing the hollow portion above the partition wall 44. Also, during the work of inserting the cable 2, the entire frame is opened at first, and the frame is closed according to the progress of the cable laying. It is possible and the laying work becomes easy.

7 to 9 show another embodiment. A lid 171 is attached to the rear end of the side plate 161, and the structure of this lid is as shown in FIG. As shown in FIG. 9, this lid is fixed to the mounting plate 14 by projecting a protrusion 171a and screwing the screw 18 into the screw hole 171a at the center of the mounting piece. The other structure is substantially the same as that of the embodiment shown in FIG. 3, and the same reference numerals are given.

10 and 11 show the structure of the top plate 1, and a plurality of reinforcing plates 13 ... Are provided on the back surface of the top plate. As shown in FIG. The leg 5 is provided on the.
