BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a desk according to the present invention.

In the first embodiment, as shown in FIGS. 1 and 2, a leg 1 which is one of the desk parts fastened to each other is used.
And the other desk parts corresponding to this, the top plate fixing frame 2,
And four (two on each side) joiners 4, 4... Are fastened to the oddly shaped elongated holes 5 and 5 'provided on the leg 1 and the curtain plate 3, which is another desk component corresponding thereto. FIG. 1 shows a state before the curtain plate is fastened to the leg 1, and FIG. 2 shows a state immediately before the top plate fixing frame 2 is attached to the leg 1 and a state after the curtain plate 3 is attached.

In this case, the left end of one half (left side) of the leg 1 is attached to the top plate fixing frame 2 for easy understanding in FIGS.
Are shown in a perspective view, and the case where the curtain plate 3 is attached to the left end of the leg 1 is omitted, and the symmetrical right side is omitted.

As shown in FIGS. 3A and 3B, an irregularly shaped elongated hole 5 having a wide portion 5a and a narrow portion 5b is formed on the mounting surface 1a, which is the upper surface of the leg 1, as shown in FIGS. The hole is formed so as to extend in the direction from the hole edge 5d at one end to the hole edge 5c at the other end.

The joiner 4 inserted into the odd-shaped long hole 5
Is made of synthetic resin (or metal) and has a size such that the periphery of the central portion is substantially fitted into the wide portion 5a of the odd-shaped elongated hole 5 as shown in a perspective view in FIG. 4a, an elastic first locking piece 4b extending perpendicularly from the side of the joiner body 4a and having a protruding locking portion 4d at the end, and the first locking piece 4b are paired. And a second locking piece 4c extending in the opposite direction with a certain distance from the joiner main body 4a so as to be in a corner relationship. Here, the narrow portion 5b of the irregularly shaped long hole 5
Is formed narrower than the wide portion 5a so that the joiner body 4a cannot be inserted.

The joiner body 4a has a first positioning portion 4e (not shown in FIG. 4) protruding from the opposite side of the first locking piece 4b, and a base end position of the first locking piece 4b. A constricted portion 4f engaging with the inner edge of the narrow portion 5b of the odd-shaped elongated hole 5 on both sides of the joiner body portion 4a, and a second positioning portion 4g protruding on the opposite side of the second locking piece 4c.
A constricted portion 4h is provided on both sides of the joiner main body portion 4a at the base end position of the second locking piece 4c so as to be engaged with the inner edge of the narrow portion 5b of the modified long hole 5.

In this case, the first positioning portion 4e and the second
The positioning portion 4g is not particularly protruded and the joiner main body 4
Alternatively, it may be based on the side of a.

In the joiner main body 4a, the opposite sides of the bases of the first locking piece 4b and the second locking piece 4c protrude outward from the positioning parts 4e and 4g, respectively, so that the joining parts 4a and 4g are stepped. The step portions 4i, 4i prevent the joiner body portion 4a from falling into the hole even when the joiner main body portion 4a is inserted into the modified long hole 5.

Next, this joiner 4 is attached to the mounting surface 1 of the leg 1.
As shown in FIG. 5 (A), when the joiner body 4a is first inserted into the wide portion 5a, the first locking piece 4b has no hole to be inserted. It deforms as shown in the figure by elasticity from the end position, and comes into contact with the locking portion 4d in a state inclined on the mounting surface 1a.

Next, the constricted portion 4f is slid to the rear side of the narrow portion 5b so as to be along the hole edge of the narrow portion 5b, and the first positioning portion 4e is moved to the end of the narrow portion 5b of the modified elongated hole 5. When the first locking piece 4b is brought into contact with the hole edge 5c of the portion, the first locking piece 4b follows and is pulled toward the wide portion 5a, and the locking portion 4d comes into contact with the hole edge 5d of the end portion and is locked. The joiner 4 is prevented from coming off at that position by the joiner main body 4a and the first locking piece 4b, and becomes a state as shown in FIG. 5B.

On the mounting surface 2a of the top plate fixing frame 2, which is the other desk part, a deformed elongated hole 5 'having the same shape as the deformed elongated hole 5 is formed in the opposite direction to the deformed elongated hole 5 as shown in the upper part of FIG. Has been drilled. Therefore, when the wide portion 5a of the modified elongated hole 5 'of the mounting surface 2a of the top plate fixing frame 2 located above in FIG. 6 is lowered toward the joiner 4 protruding from the mounting surface 1a of the leg 1, the second portion is inserted. Since the locking piece 4c has no hole to be inserted, it is deformed from the base end position by elasticity and comes into contact with the locking portion 4d in a state inclined to the mounting surface 2a.

Next, in order to make the constricted portion 4h follow the edge of the hole of the narrow portion 5b, the second positioning portion 4g is slid to the depth side of the narrow portion 5b side as shown by an arrow, and the width of the second positioning portion 4g is changed to the width of the modified elongated hole 5 '. When contacting the hole edge 5c at the end of the narrow portion 5b, the second locking piece 4c
Following this, the locking portion 4d is elastically brought into contact with the hole edge 5d at the end of the wide portion 5a and locked, so that the joiner 4 is connected to the joiner body portion 4a and the first locking piece 4b. At that position, and attached in the state shown in FIG.

Thus, the leg 1 and the top plate fixing frame 2 are fastened via the joiner 4 to the mounting surface 1a and the mounting surface 2a.

In the figure, reference numeral 6 denotes a top plate. When the top plate 6 is lowered, the top plate 6 engages with the top plate fixing frame 2 as shown in FIG.
Is mounted on the mounting surface 1a, so that the top plate 6 is assembled to the leg 1.

The above is the case of assembling, but the disassembly can be performed by removing the joiner 4 from the leg 1 or the top plate fixing frame 2.

That is, when the joiner 4 is to be removed from the top plate fixing frame 2, the locking portion 4 d of the second locking piece 4 c is pushed down while the top plate 6 is removed as shown in FIG. The top plate fixing frame 2 can be removed from the joiner 4 by sliding the joiner body portion 4a engaged with the narrow portion 5b of the odd-shaped long hole 5 'of the mounting surface 2a so as to come to the wide portion 5a. .

When the joiner 4 is to be removed from the leg 1, the leading end of the first band plate 4b is pinched and lifted in FIG. 5B, and the locking portion 4d is removed from the hole edge 5d.
By sliding the joiner body 4a from the narrow portion 5b to the wide portion 5a as shown in FIG.
Can be easily removed.

FIGS. 3 to 8 show the case in which the top plate fixing frame 2 is fastened to the leg 1. The same applies to the case in which the curtain plate 3 is fastened to the leg 1. A hole 5 and a modified elongated hole 5 'are provided in the mounting surface 3a on the side of the curtain plate 3, and the same joiner 4 is mounted to fasten the mounting surface 1b and the mounting surface 3a.
