Description

[Detailed description of the invention] (Field of industrial application) The present invention has a good appearance, and can be used to attach top plates of various sizes by simply replacing or omitting some parts as necessary. Regarding assembly desks.

(Prior art) Four leg rods supporting the top plate are connected by a horizontal connecting rod, and by replacing the connecting rod with one of the required length, the top plate with different dimensions can be made. Assembly desks capable of supporting .

(Problems with the prior art) However, in such a conventional assembly desk, from the standpoint of stability, it is not possible to make the distance between the leg rods extremely narrow, and therefore the dimensions of the top plate that can be adopted are limited. limited.

(Purpose of the invention) The present invention allows the spacing of the top support parts to be changed over a wide range by simply replacing some parts.
Moreover, it is an object of the present invention to provide an assembly desk which has excellent stability of the leg levers at all times, has no external protrusions, and has an extremely good appearance.

(Structure of the invention) The present invention has a pair of front and rear leg rods made by bending a square pipe into a U-shape when viewed from the side. Connecting rods facing the front and back directions are interposed in the upper and lower parts, and coaxial holes with different diameters are bored in the locations corresponding to the connecting rods on both back rods, with the large diameter hole on the outside. Insert the stepped bolt in such a way that the tip of its enlarged diameter head does not protrude to the outside surface of the back rod, and insert the threaded portion of the stepped bolt through the small diameter hole in the coaxial different diameter hole of the connecting rod. By screwing into the nut fixed inside the end, the front and rear 1
A pair of leg rods is connected to form a leg body, and the two leg bodies are arranged on the left and right, and a horizontal rod facing in the left and right direction interposed between them is connected in the same manner as described above using the stepped bolt. Furthermore, a top plate is supported on the upper bending rods of a pair of left and right legs.

(Embodiment) FIGS. 1 and 2 show a first embodiment of the present invention.

1, 1 is a square pipe-shaped base rod 2 that extends in the vertical direction.
The upper and lower ends of are bent in the same direction 3, 3,
A pair of front and rear leg rods are U-shaped in side view, and both leg rods 1, 1 are placed back to back with a required distance between them.

Reference numeral 4 designates two pairs of upper and lower small circular holes drilled in the opposing surfaces of both back rods 2, and circular holes 5 with a slightly larger diameter than the small circular holes 4 are drilled in corresponding locations on the opposite surfaces of each back rod 2. It is set up.

6 is a pair of upper and lower connecting rods, facing in the front-back direction;
A connecting fitting 8 having a nut 7 fixed inside thereof is fitted to both ends thereof.

The connecting rod 6 has a circular hole 5 and a small circular hole 4 of the back rod 2.
By screwing the threaded portions of a pair of left and right stepped bolts 9 inserted from the outside into the nut 7, the leg rods 1, 1 are suspended horizontally, and the pair of front and rear leg rods 1 and the upper and lower legs 1 are connected. The pair of connecting rods 6 constitute a leg body 10.

The stepped bolt 9 is designed to fit properly into the circular hole 5 and not protrude from the outer surface of the circular hole 5, and its threaded portion is properly fitted into the small circular hole 4. It's getting wet.

The legs 10 are arranged as a left and right pair, with a predetermined interval left and right, as shown in FIG.

The left and right legs 10 each have a rectangular pipe-shaped horizontal rod 11 which faces in the left-right direction and has connecting fittings 8' having the same structure as the connecting piece 8 fitted at both ends, and a bent rod 3 at the lower part of the leg rod 1. Fasten to the leg rod 1 by inserting stepped bolts 9' from the outside into circular holes 5' and small circular holes 4' drilled in the outer and inner surfaces near the base of the are connected by.

Reference numeral 12 denotes a rectangular top plate in which bottomed screw holes 13 are bored from the lower surface of the four corners. It is fixed onto both legs 10 by screwing stepped bolts 9'' inserted from below into the circular holes 5'' and small circular holes 4'' bored into the screw holes 13.

Reference numeral 14 denotes a closing member made of rubber or the like fitted to the tips of the upper and lower bending rods 3, 3' of the leg rod 1, and 15 refers to a buffering member attached to the lower end of the lower bending rod 3'. It is.

FIG. 3 shows how to use the connecting rod 6 in the first embodiment by omitting it, and the same members as those in the first embodiment are given the same reference numerals and the explanation thereof will be omitted.

Round hole 5 of leg rod 1 on the front side (right side in Figure 3)
A horizontal cylindrical nut 17 with a screw hole 16 bored in the rear surface is inserted from the front into the circular hole 5 and small circular hole 4 in the back rod 2 of the rear leg rod 1 from the rear. By screwing the threaded portion of the stepped bolt 9 into the screw hole 16, the front and rear leg rods 1,
1 is connected with the base rods 2 in contact with each other.

In this case, the longitudinal length of the top plate 12' is the first
From the longitudinal length of the top plate 12 in the embodiment, the connecting rod 6
becomes shorter by the length of .

In addition, what is shown by the imaginary line in FIG. 3 is the same method using a taller leg rod 1.

FIG. 4 shows a second embodiment of the present invention.
The same members as those in the first embodiment are given the same reference numerals.
The explanation will be omitted.

18 is a pair of upper and lower L formed by bending a square pipe.
In the L-shaped rod, both ends of a square pipe-shaped connecting rod 19 whose outer diameter is approximately equal to the inner diameter of both L-shaped rods 18 are fitted into the opposing ends of the vertical rods of the L-shaped rods 18. 18 and the connecting rod 19 have circular holes 5, 5''''' and small circular holes 4, 4, and 5'' bored on the outer and inner surfaces of their corresponding locations.
Connecting rod 6 is tightened by stepped bolt 9 inserted into
They are fastened together.

The first embodiment of the present invention is constructed as described above, and if a plurality of connecting rods 6 with different longitudinal lengths and a plurality of horizontal rods 11 with different left-right lengths are prepared, connecting rods 6 of different lengths can be connected. By appropriately selecting the horizontal rods 11 and 11, it is possible to easily provide various types of desks with different lengths from front to back and from side to side.

Furthermore, since the leg rods 1 are U-shaped, the connecting rods 6 can be omitted and the front and rear leg rods 1 can be brought into contact with each other, as shown in the third diagram, to provide a desk with a different aesthetic appearance.

Moreover, the stepped bolts 9 for connecting the connecting rods 6, etc. do not protrude beyond the outer surface of the leg rods 1 at all, so they look good and do not get in the way or get things caught. do not have.

Also, as in the second embodiment, the leg rods can be replaced with L-shaped rods 18.
and a connecting rod 19, with connecting rods 19 of different lengths.
You can use this to change the height of the top plate. Moreover, in this case, one stepped bolt 9
Since the connecting rod 6, L-shaped rod 18, and connecting rod 19 can be connected, assembly work is easy.

As described above, the present invention is convenient and has a good appearance because various types of desks with different left and right or front and back lengths can be easily provided by selecting the members.
