DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a table according to an embodiment of the present invention will be described with reference to the drawings. The folding table includes a leg A and a base B. These are described in detail below.

[Regarding leg portion A shown in FIG. 1 (a)] The leg portion A has four legs 1, and a telescopic portion 2 is provided between each leg 1.
A fixed connecting part 3 is attached to the upper end of each leg 1, and a movable connecting part 4 is inserted into the upper part of each leg 1 so as to be vertically movable. In each of the telescopic portions 2, a pair of links 5 and 6 crossing each other in an X-shape form a support shaft 7 at the crossing portion.
The upper ends of the links 5 and 6 are rotatably supported by a shaft 3a with respect to the fixed connecting portion 3 of each leg 1, and are rotatably supported along the vertical surface. The lower ends of the links 5 and 6 are rotatably supported by the shaft 4a with respect to the movable connecting portion 4 on each leg 1. The leg portion A can take an unfolded state shown in FIGS. 1 (a), 2 (a), 3 (a) and 4 (a) and a folded state shown in FIG. 4 (b). It has become. In this unfolded state, the movable connecting part 4 of each telescopic part 2 moves up along each leg 1 and comes closest to each fixed connecting part 3, and each link 5, 6 is pushed open, so that each leg 1 is expanded. The most distant. In this folded state, the movable connecting part 4 of each telescopic part 2 is connected to each leg 1.
And move down to be the most distant from each fixed connecting part 3,
Each link 11 and 12 is pushed and narrowed, and each leg 1 is closest.

In each of the fixed connecting portions 3, FIG.
As shown in (b), a pair of elastic locking arms 8 project upward and form a cylindrical shape, and a circular insertion hole 9 is formed inside thereof. A cut portion 10 is formed between the upper portions of the holes and communicates with the insertion hole 9.
A locking portion 11 is protruded from the upper outer side of the elastic locking arms 8. The split portion 10 can be expanded between the locking portions 11 of the elastic locking arms 8 against the elastic force.

[Regarding the base portion B shown in FIGS. 1A and 1B] The base portion B has two base plates 12 on both sides and two base plates 13 at the center. The base plates 12 and 13 are joined by folding edges 14 adjacent to each other, and the folding edges 14 of the central base plates 13 are connected to each other by a pair of embedded hinges 15 (connecting portions). And the folding edges 14 of the central base plates 13 are connected to each other by a pair of hinges 16 (connecting portions) on the lower side (back side) thereof. And FIG.
(A), as shown in FIG. 2 (a), FIG. 3 (a) and FIG. 4 (a), each of the base plates 12, 13
4 and a folded state in which the base plates 12, 13 are folded at the folding edges 14 and overlapped with each other as shown in FIG. 4B. ing.

A pair of leg receiving brackets 17 are attached near the hinges 16 on the back side of the both side base plates 12, respectively. In each of the leg receiving brackets 17, the inside hole 1
A locking hole 18 composed of the inner hole 9 and the outer hole 20 is formed, and the outer hole 20 opens the inner hole 19 to the back side. At the boundary between the inner hole 19 and the outer hole 20, locking edges 18a (locking) are provided on both sides of the outer hole 20 along a direction orthogonal to the direction in which the folding edge 14 extends. Part) is formed in a step shape.

[About the case where the leg A is attached to the base B] As shown in FIGS. 2A and 2B, both elastic locking arms 8 of each leg 1 are attached to each leg support of both side base plates 12. The engaging portion 18 of the metal fitting 17 is engaged with the notch portion 10 of the elastic locking arm 8, and the cutout portion 10 of the elastic arm 8 is engaged with the inner hole portion 19 of the locking hole 18 through the outer hole portion 20. In this state, the insertion hole 9 between the two elastic locking arms 8 is outside each leg receiving bracket 17.

Then, as shown in FIGS. 3A and 3B,
Of the four elastic locking arms 8, two sets of two elastic locking arms 8 adjacent to each other between both side base plates 12, and one stopping rod is provided in each of the two insertion holes 9. 21 is inserted.
With this stop rod 21, the split portion 1 of both elastic locking arms 8
0 is expanded, and the locking portions 11 of the two elastic locking arms 8 are separated from each other and locked by the both locking edges 18 a in the locking holes 18. Accordingly, each leg 1 is attached to both side base plates 12 in a state where both elastic locking arms 8 are securely held in the locking holes 18.
The two stop rods 21 are provided on the folding edges 14 of the respective base plates 12 and 13.
Intersect at right angles to.

[Removal of Leg A from Base B] In the assembled state shown in FIGS. 3 (a) and 3 (b), the two stop rods 21 are moved from between the two elastic locking arms 8 of each leg 1. Fig. 2
The state shown in FIGS. Further, when the two elastic locking arms 8 of each leg 1 are pulled out from the locking holes 18 of each leg receiving bracket 17, the disassembled state shown in FIGS. 1A and 1B is obtained.

This embodiment has the following feature (a). (A) Unless the stop rod 21 is forcibly pulled out of the insertion hole 9 between the elastic locking arms 8, the locking portions 11 of the elastic locking arms 8 do not expand each other, and The locking edge 18a is reliably locked. Therefore, each leg 1 can be reliably held on each leg receiving bracket 17.

In addition to the above embodiment, the following (a) to (c)
It may be configured as follows. (B) One stop rod 2 for each elastic locking arm 8 of each leg 1
Introduce 1. (B) In the leg portion A, the telescopic portion 2 is eliminated, and a spacing rod is integrally or detachably connected between the legs 1 instead.

(C) At the base portion B, a base plate is provided integrally so as not to be foldable. The technical ideas (other than the claims) that can be grasped from each embodiment are described together with the effects. (A) In the leg portion A of the first aspect, one stop rod 21 is inserted between the two elastic locking arms 8 on the plurality of legs 1 among the legs 1. Therefore, the required number of stop rods 21 can be reduced, and the number of parts can be reduced.

(B) In the base portion B of the first aspect, the plurality of base plates 12 and 13 are joined to each other at adjacent folding edges 14 and arranged side by side, and the plurality of base plates 12 and 13 are arranged side by side.
Each of the base plates 12 and 13 is folded so as to be folded at the folding edge 14 and overlapped with each other.
The connecting portions (embedded hinges 15 and hinges 16) are provided between the folding edges 14. Therefore, when not in use, the base B can be compactly assembled.

In the leg portion A of (a), the stopper rod 21 crosses the folding edge 14 of each of the base plates 12 and 13. Therefore, at the time of use, each of the base plates 12 and 13 abuts on each other at the folding edge 14 to maintain the expanded state. In addition, each of the base plates 12 and 13 is brought into the folded state by the two retaining rods 21. And the deployed state can be held more reliably.

(C) In the leg portion A according to the first aspect, an extendable portion 2 is provided between the plurality of legs 1 so that the legs 1 are folded close to each other. Therefore, when not in use, the legs A can be compacted.

[0024]

According to the present invention, the locking portion (11) of the two elastic locking arms (8) with respect to the locking portions (18a) of the locking hole (18) by using the locking rod (21). ) Can be maintained, and each leg (1) can be securely connected to the base plate (12).
