The attached pin (24a) can be mounted by inserting it into the upper and lower locking grooves (20), (20) from either side end of the mounting plate (7).
[0022]
As shown in FIG. 1 to FIG. 4, the planar shape is the cross-sectional shape of the support column (25) for supporting the shelf board etc. A bottomed receiving hole (26) having a substantially similar shape slightly larger than a bullet-shaped (non-circular) outer shape facing forward is formed, and a column ( 25) A resectable portion (27) is formed which is complementary to the cross-sectional shape of the portion excluding the rear end portion.
[0023]
Each post (25) is fitted from behind to a notch (28) formed at the rear edge of the top plate (5) by cutting out this excisable portion (27), and each post (25) The lower end is fitted into the receiving hole (26) with a bottomed cylindrical receiving seat (29) made of an elastic body such as rubber or synthetic resin material interposed therebetween, and the receiving hole (26) Front and rear through-holes (30) and (30) provided in the bottom of the base and front and rear through-holes (31) and (31) provided in the bottom (29a) of the receiving seat (29). ) And (32) are screwed into the screw holes (33) and (33) provided at the lower end of each support column (25), so that each support column (25) is firmly fixed to the rear part of each support rod (2). However, it can be erected so as to form a pair on the left and right at the rear of the top plate (5).
[0024]
As clearly shown in FIG. 2, the receiving seat (29) is composed of a bottom portion (29a) having substantially the same shape as the lower end surface of the support column (25) and a cylindrical portion (29b) standing up from the outer peripheral edge thereof. In the center of the cylinder part (29b) before and after, notches (34) and (34) are provided from the upper end to the lower end.
In addition, ribs (35) and (36) facing in the vertical direction are provided at appropriate positions on both side surfaces of the outer peripheral surface of the cylindrical portion (29b) and both side edges of each cut (34). On the outer surface of the substantially upper half of these ribs (35) and (36), inclined surfaces (35a) and (36a) are formed that slightly expand outward and upward.
[0025]
The wall thickness of the cylindrical portion (29b) of the receiving seat (29) is substantially the same as the gap formed between them when the lower end of the column (25) is fitted in the center of the receiving hole (26) or Slightly larger, when the receiving seat (29) is fitted to the lower end of the column (25), and when they are fitted to the receiving hole (26), the upper part of the rib (35) (36) Is compressed so that the lower end of the column (25) cannot move in the receiving hole (26).
[0026]
A blocking plate (37) is fixed to the inner surface of the lower end of the hollow support column (25) by welding, and a pair of front and rear screw holes (33) (33) are provided therein.
[0027]
As shown in FIG. 1, a slightly lower rear surface of the support plate (38) facing in the front-rear direction is fixed to the upper end of each column (25), and the left and right support plates (38) (38) are attached to the shelf ( 39) and cabinet (40) can be supported.
[0028]
In order to remove each support column (25) from the desk (1), it is only necessary to remove the front and rear bolts (32) and (32) and then pull out each support column (25) from the receiving hole (26). Also, by removing the receiving seat (29) remaining in the receiving hole (26) while being fitted to the end of the support post (25), it is possible to easily separate different materials. be able to.
[0029]
In the above-described embodiment, the cross-sectional shape of the support column (25) is a forward shell shape, but is not limited to this, and may be, for example, a rectangular tube shape or other non-circular shape.
[0030]
【The invention's effect】
According to the first aspect of the present invention, the receiving seat is fitted to the lower end portion of the support column, is fitted to the receiving hole of the support rod, and the lower end of the support column is supported by the bolt from below the bottom portion of the receiving hole. By fastening to the heel, the support can be easily attached to the desk, the structure is simple and can be manufactured at low cost, and there is no need to provide a long insertion part at the lower end of the support, unlike the conventional one. Therefore, the overall length of the support can be shortened to facilitate transportation, and the weight can be reduced.
Further, since the support column, the support rod, and the receiving seat can be easily separated, they can be easily separated according to the material at the time of disposal, which can contribute to the reduction of the burden on the environment.
[0031]
According to the second aspect of the present invention, by providing the notch in the receiving seat, the receiving seat can be easily attached to and removed from the lower end portion of the support column and the receiving hole of the supporting rod, and fitted into the receiving hole of the supporting rod. Thus, the elastic deformation of the receiving seat can be effectively absorbed.
[0032]
According to the third aspect of the present invention, the receiving seat can be easily inserted into the receiving hole of the support rod, and the support post can be stably supported by specifying the portion to be compressed of the receiving seat.
[0033]
According to the fourth aspect of the present invention, the receiving seat can be easily inserted into the receiving hole of the support rod, and after the insertion, the supporting post is firmly gripped on the opening side of the receiving seat, thereby strengthening the supporting post. Can be held.
[0034]
According to the invention described in claim 5, the appearance of the top plate can be improved when the support is not provided, and when the support is provided, the notch formed by excising the excisable portion of the top plate. By fitting the front part of the column, it is possible to prevent the column from tilting forward.
