Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a desk.

[Problems to be solved by conventional techniques and devices]

In general, desks are often disassembled for transportation and assembled in places where they are to be used.In the past, when assembling, the operator could enter the lower position of the top plate to perform work, or lean the legs. I was working.

Therefore, it is an object of the present invention to provide a desk which can be easily and quickly disassembled and assembled, and which is extremely strong when assembled.

[Means for Solving the Problems]

In order to achieve the above object, the desk according to the present invention comprises:
A desk having a top plate mounted on a horizontal inner top plate, wherein the inner top plate placed on a leg and / or a sleeve box is connected to the leg and / or by a vertical screw that is screwed from above. Alternatively, a curtain plate attached to a sleeve box and having a curtain plate catching on the rear end edge of the inner top plate may be used in the state where the curtain plate catcher is hooked on the rear end edge of the inner top plate. The top plate is hung vertically from the vicinity of the rear edge of the top plate, and the curtain plate is attached to the legs and / or the sleeve box by horizontal screws screwed from the rear side. Also, at the left and right ends of the curtain plate, electric wiring passages along the vertical direction are provided,
Further, it is preferable that the outer opening of the passage is covered with a cover and the upper opening of the passage is covered with a cap.

[Action]

When attaching the inner top plate to the leg and / or the sleeve box, the vertical screw may be screwed from above, so that the inner top plate can be attached without making the leg and / or the sleeve box sideways. Can be installed. Also, when installing the curtain plate, hook the curtain plate receiver on the rear edge of the inner top plate, and the curtain plate will be held by the inner top plate. If it is screwed, the curtain plate can be attached to the legs and / or the sleeve box, and the operator does not need to screw the screw while holding the curtain plate.

In addition, when the legs are used, the assembled desk can securely hold the legs in the vertical state by using the assembled curtain plate.

Moreover, by providing the electric wiring passage on the curtain plate, the electric wiring of the office equipment or the like placed on the desk can be connected to the power source or the like through the passage.

Further, casters 95 are provided on the lower surfaces of the leg 1 and the sleeve box 2, respectively.
Is attached.

Next, a method of assembling this desk will be described with reference to FIG.

First, the inner top plate 3 is placed on the upper surfaces of the leg 1 and the sleeve box 2, and the inner top plate 3 is attached to the leg 1 and the sleeve box 2 with the vertical screws 20 ... Next, the curtain plate receivers 83, 83 of the curtain plate 5 are locked to the rear wall 23 of the rear frame 8 of the inner top plate 3, and the curtain plate 5 is hung from the vicinity of the rear end edge of the inner top plate 3. . In this case, the front walls 49, 49 of the side frames 45, 45 of the curtain plate 5 are in contact with the rear end surface of the leg 1 or the rear end surface of the sleeve box 2. Then, in this state, the curtain plate 5 is attached to the leg 1 and the sleeve box 2 by the horizontal screws 96 ... Ie horizontal screws
96 is inserted into the side frame 45 through a through hole (not shown) formed through the rear wall 50 of the side frame 45, and the front wall 49 of the side frame 45 and the rear end surface of the leg 1 (or sleeve box). 2 rear end surface). A cap 97 is attached to a through hole (not shown) in the rear wall 50 of the side frame 45.

Next, as shown in FIG. 5, with the respective slide bodies 32 ... Corresponding to the wide portions 17 of the groove 16 of the inner top plate 3, the top plate 4 is placed on the inner top plate 3, The respective slide bodies 32 are fitted into the wide portions 17 to bring them to the state shown in FIG. 16 (II), and from this state, the top plate 4 is brought into contact with the rear stopper portions 18, 18 by the rear slide bodies 32, 32. Slide it to the rear to reach the state shown in Fig. 16 (I). Then, in this state, the fixture 41 is screwed onto the top plate 4 from below through the slit 24 of the inner top plate 3 to fix the top plate 4. In this case, as shown in FIG. 11, the top plate 4
The rear edge member 30 comes into contact with the upper edge 82 of the rear surface wall 47, and the electric wiring housing portion 80 is put into a covered state. In addition, covers 55,5
By attaching 5 to the side frames 45, 45 of the curtain plate 5 and attaching the cap 68 to the upper ends of the side frames 45, 45, the desk as shown in FIG. 4 is completed. It is also preferable to provide a drawer 98 below the inner top plate 3 as shown by phantom lines in FIGS. 2 and 3.

In the desk configured as described above, the top plate 4 slides on the inner top plate 3 in the front-back direction by a predetermined dimension L (see FIG. 5) when the fixing tool 41 is loosened (unlocked state). As shown in FIG. 16 (II), the storage part 80 is in the open state when the top plate 4 is slid forward. Therefore, in this state, the top plate portion 6, that is, the top plate 4
The electrical wiring of office equipment such as a word processor (not shown) placed on the storage unit 80 is stored in the storage unit 80, and then the top plate 4 is slid backward to cover and then the fixing tool 41 is tightened. (Locked state), the top plate 4 is fixed, and it is not necessary to place electric wiring of office equipment or the like on the top plate part 6, and a sufficient space on the top plate part 6 can be secured, Moreover, the top plate portion 6 becomes clean. In addition, the electrical wiring from the office equipment, etc., the hollow body portion 30 of the rear edge member 30.
Since b is elastically deformable, it is possible to easily form a hole through which the wiring can be inserted between the upper end edge portion 82 of the back surface wall 47 and the rear end edge member 30, and through this hole, The wiring is a storage
