That is, the top plate is fitted with a projection provided forward and horizontally on a block fixed to the rear side of the side panel, into a hole formed on the non-use end side thereof,
The bolts are tightened from below the top plate on the use end side with the protrusions sufficiently fitted in the holes. In such a structure, the protrusion prohibits the left and right and up and down movements of the non-use end side of the top plate.

[0003]

By the way, in the above configuration, the opposite end of the top plate has only the projection and the hole fitted, and the projection attached to the side panel side has Neither does it act to pull the top plate toward the side panel, nor does it pull the top plate toward the back. In addition, even at the use end side of the top plate, the top plate is attracted to the side panel by bolts, but the top plate is not pushed toward the non-use end side. Therefore, when the inner diameter of the hole and the outer dimensions of the projection are not within the predetermined dimensional error range, the non-use end side of the top plate will rattle in either the left, right, up, or down direction.

[0004] In such a configuration, the number of bolts is reduced because the bolts are tightened at two locations on the top plate.
As a result, the number of bolt tightening operations is reduced, so that the number of parts can be reduced. However,
The bolt tightening work must be performed upward from below the top plate to prevent the bolt from being exposed from the top plate, and although the bolt tightening work is reduced, it is not always possible to work in an easy posture and the work is not always easy. Not something.
An object of the present invention is to solve the above-mentioned problems with a simple structure.

The frame 6 is formed, for example, by forming a rectangular frame from a pipe material having a square cross section, and connecting the two rectangular frames with their long sides up and down and leaving the width of the storage space 2. I have. Then, the side panel 4 is fixed to one side surface of the two frame members 6, the other side surface is arranged to face the other side, the intermediate leg 5 is fixed to the other side surface, and the tabletop 1 is removed. The main parts of the 100 are connected at their opposing surfaces and have sufficient depth to accommodate cords. The upper surface opening 21 of the storage space 2 which becomes the upper part of the frame 6 is closed by the duct cover 3 so as to be openable and closable, and a back plate 61 is attached to the front surface thereof to cover cords stored in the storage space 2. It is designed to hide.

In such a configuration, the respective top plates 1 are mounted in the order described below. First, the top plate 1 is placed on the leg element FE formed by the side panel 4, the intermediate leg 5, and the frame 6 with the use end 1 a side in front. At this time, the balance member 71 of each of the fastening members 7 is
The other end 71b is raised and the hook-shaped portion 71
a is below the top plate mounting surface 42b. From this state, when the top plate 1 is pushed into the non-use end 1b side and slid, the slide movement causes the front engagement hole 1 of the top plate 1 to move.
4 engages with the hook-shaped claw 45. After the top plate 1 is slid in this manner, the other end 71b of the balance member 71 is connected to the leg element F.
In order to tighten the bolt E, the bolt 72 is inserted into the oblong hole 71c and screwed into the nut 42e. By this bolt tightening operation, the balance member 71 rotates toward the non-use end 1 b of the top plate 1, and the tip of the hook-shaped portion 71 a of the balance member 71 is moved to the rear edge of the rear engagement hole 15 of the top plate 1. The hook-shaped portion 71a pushes the rear edge 15a of the rear engagement hole 15 in the direction of the non-use end 1b from the state where the top plate 1 is slid, and is further drawn into the non-use end 1b side from the position where the top plate 1 is slid. When the bolt 72 is completely tightened, the hook-shaped portion 71a stands vertically and fixes the top plate 1. In this tightening, the top plate 1 further moves from the slide movement position to the non-use end 1b side, so that the hook-shaped claw 45 is locked to the distal end portion 14a in which the width of the front engagement hole 14 is reduced, The engagement state becomes strong.

After the four corners of the top plate 1 are fixed as described above, the middle position of the non-use end 1b of the top plate 1 is fixed by the locking metal member 61. The locking fitting 61 is made of sheet metal and has a base 6.
A through hole 61b is provided at the center of the base 1a for fixing.
An engagement piece 61d having a 1/4 circular engagement portion 61c formed at the tip is provided on the left and right sides of a. The engaging portion 61c of the locking metal member 61 is moved and inserted into the slit 16 of the top plate 1 while rotating the engaging piece 61d from the upper side to the lower side,
The base 61a is fastened to the upper surface of the frame 6. Therefore, the top plate 1 is fixed at the intermediate position on the non-use end 1b side while being slightly attracted to the locking piece 61d on the non-use end side.

As described above, the mounting of the top plate 1 can be completed without the operation of sinking below the top plate 1. That is,
The mounting work is performed by placing the top plate 1 on the leg element FE and
By sliding to the b side and tightening the tightening fitting 7 with the bolt 72, the operation is completely completed. Since the work of tightening the bolt 72 is performed from the upper side of the top plate 1, it does not force the posture. Since the hook-shaped claw 45 is firmly engaged with the front engagement hole 14 on the use end 1a side of the top plate 1, the top plate 1 is operated by the tightening mechanism BM with a simple structure. It can be fixed without tightening. In addition, since the top plate 1 is not only fixed on the non-use end 1b side but also fixed in a tensioned state on the non-use end 1b side, it is possible to prevent rattling in the vertical direction. . Further, the middle part of the non-use end 1b of the top plate 1 is locked
Therefore, even if the top plate 1 is long, the anti-use end 1b does not rattle at an intermediate portion thereof.

The present invention is not limited to the embodiment described above. For example, as the leg element FB, only the two side panels 4 are provided with the side panel 4 and the drawer, in addition to the side element 4, the frame 6 and the intermediate leg 5 as in the above embodiment. It may be constituted by a sleeve portion and further by two sleeve portions.

The front engaging hole 14 and the hook-shaped claw 45 forming the slide engaging portion SE are opposite to the above embodiment,
The front engagement hole 14 may be formed in the leg element FE, and the hook-shaped claw 45 may be provided on the lower surface of the top plate 1. Alternatively, the front engagement hole 14 is a Daruma hole formed by integrally forming two round holes of different sizes, and the hook-shaped claw 45 is a stepped pin having a tip portion formed to have a larger diameter than the body. It may be a configuration.

Further, as the fastening 7, FIGS.
As shown in FIG. 2, the upper surface portion 171a of the balance member 171 is pressed and rotated by the top plate 1, and the hook-shaped portion 171b is engaged with the rear engagement hole 15 of the top plate 1. You may. That is, in this modification, the tightening members 7
When the balance member 171 is tilted when is attached to a predetermined position, the step 1 of the support member 173 of the tightening member 7
The upper surface portion 171a of the balance member 171 is inclined and exposed at 73a. Since the balance member 171 is attached to the support member 173 in this manner, when the top plate 1 is attached, when the top plate 1 is first pushed into the non-use end 1b and slid, the top plate 1 is slid. A hook 45 engages with the front engagement hole 14 of the plate 1 and
The lower edge of the non-use end 1b of the top plate 1 abuts against the upper surface portion 171a of the balance member 171 and pushes it down, so that the balance member 171 is pressed.
And stop. In this state, the hook-shaped portion 171b of the balance member 171 has almost entered the rear engagement hole 15 of the top plate 1. Thereafter, if the bolt 72 is inserted into the bolt hole 171c at the rear end of the balance member 171 and tightened, the balance member 171 is further rotated to maintain the horizontal position, and at the same time, is engaged with the rear engagement hole 15 and 1 is further pulled in the direction of the non-use end 1b, and the top plate 1 is firmly fixed. With such a configuration, at the same time as the hook-shaped claw 45 is engaged with the front engagement hole 14 on the use end 1a side of the top plate 1,
Since the hook-shaped portion 171b of the balance member 171 enters the rear engagement hole 15, the top plate 1 can be temporarily fixed before the balance member 171 is tightened. In addition, the configuration of each unit is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention.

[0023]

According to the present invention, as described in detail above, the top plate is fixed by the slide engagement portion for engaging the top plate with the leg element and the tightening mechanism for tightening the balance member with the screw element. Although it has a simple structure, the number of parts to be tightened by screw elements can be reduced, and the tightening work can be performed from the top of the top plate, eliminating the need to take an unreasonable posture during work In addition, since the work place is not limited, the work can be performed with a normal tool, and thus the work content can be simplified.
