Abstract

PROBLEM TO BE SOLVED: To provide a structure for folding legs which can be locked automatically at the last process of putting up the legs. SOLUTION: A slide lock board with resilience of a spring is put between a leg, which can be upright and is mounted on the bottom of furniture as it can rotate, and the bottom of the furniture. The leg can be put up by sliding a lock pin inserted along a long hole formed on the slide lock board. A head of the large diameter of the lock pin is automatically inserted into a hole with a large diameter made at the end of the long hole at a position where the leg becomes upright by resilience of the slide lock board, and the leg is locked to be upright. Pushing the slide lock board against the resilience disengages to join the hole with the large diameter and the head of the large diameter of the lock pin, causes the lock pin to slide along the long hole, and enables the leg to turn to a position for folding the leg.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding leg for furniture.

[0002]

2. Description of the Related Art Conventionally, various furniture such as tables and chairs whose legs are freely foldable in order to reduce the size when not in use and to facilitate storage are known. For example, outdoor tables are carried or stored. For this reason, legs that can be freely folded are generally used widely. Such a foldable leg of furniture requires a mechanism for locking the leg in an upright state in order to stably support furniture such as a table. As a conventional leg locking mechanism, a mechanism in which one end is rotatably connected to the bottom surface of furniture so as to be locked by locking the other end of the stay to an upright leg is generally used. However, in the leg lock structure by locking the stay, two-stage operation of standing the leg and locking the stay is required for locking the leg, which is inconvenient and troublesome.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a folding structure of a leg in which the leg is automatically locked at the final stage of the operation of erecting the leg.

[0004]

In order to solve the above-mentioned problems, a means adopted by the present invention has a spring elasticity between a leg which can be freely pivoted on a bottom surface of the furniture and a free-standing leg and a bottom surface of the furniture. A slide lock plate is bridged over, and a lock pin planted on a leg is slid along an elongated hole formed in the slide lock plate to enable the leg to be erected. The large-diameter hole formed at the end of the lock pin automatically locks the large-diameter head of the lock pin to lock the legs in the upright position, and pushes the slide lock plate against the elasticity to push the large-diameter hole. And the large diameter head is disengaged, the lock pin can slide along the long hole, and the leg can be turned to the folded position.

[0005] The slide lock plate is characterized by being formed of a spring plate having rebound resilience, or a spring is adjusted on the slide lock plate to have rebound resilience.

[0006] The furniture is an outdoor table that can be stored in a form that can be carried by storing the legs on the bottom surface of the table plate.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below. According to the present invention, a slide lock plate having spring elasticity is bridged between a leg that is pivotally attached to a bottom surface of furniture and a free standing leg and a bottom surface of the furniture, and a leg is formed along an elongated hole formed in the slide lock plate. The standing of the leg is made possible by sliding the lock pin planted on the end of the slide. Automatically engages the head and locks the legs in the upright position, and disengages the large-diameter hole from the large-diameter head by pushing the slide lock plate against the elasticity, thereby locking the pin. Can be slid along the long hole so that the leg can be turned to the folded position. The foldable leg according to the present invention can be applied to various furniture legs such as a table and a chair, and is not limited to the outdoor table which can be folded and carried as described in the embodiment. The elasticity of the slide lock plate is most preferably formed of a material having elasticity.
Needless to say, a structure having elasticity may be obtained by combining a plate member having no elasticity with a spring plate.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, (1) is an outdoor table provided with folding legs to which the present invention is applied, which is obtained by folding a table plate (2) and legs (3) shown in FIG. 2
It is possible to make the table plate and the legs shown in FIG. As shown in FIG. 1, the table plate (2) can be folded in half from the center to make it a small size suitable for carrying, and it is developed to create a wide table surface and locked in the developed state. A table plate lock mechanism (4) is provided. One side of the table (2) has a handle (5) for carrying
Is attached. The leg (3) can be folded and stored in the bottom surface of the table board. By folding the leg (3) and further folding the table board (2), the portable form shown in FIG. It can be in the form.
The leg (3) can be locked by the slide lock mechanism (6) so that the leg shown in FIG. 2 is opened.

Referring to FIGS. 3 to 5, the leg (3) has its upper end pivotally attached to the bottom surface of the table (2). Leg (3)
The lock mechanism (6) for unfolding from the folded position and locking it at the support position includes a slide lock plate (7) and a lock pin (8) engaged with the slide lock plate (7). One end of the slide lock plate 7 is rotatably supported on the bottom surface of the table plate 2. The slide lock plate (7) is formed with an elongated hole (9) in which a lock pin (8) is slidable. A daruma hole is formed continuously with the hole. Lock pin (8)
Has a small-diameter portion (8a) planted on the leg (3) and a large-diameter head (8b). As shown in FIG. 3, the small diameter portion (8
a) is inserted into the slot (9) of the slide lock plate (7) and
It can be freely slid along (9), and as shown in FIG. 4, the large-diameter head (8b) is engaged with the large-diameter hole (10) at the end to be locked. Slide lock plate
(7) is preferably formed of a spring plate having rebound resilience, and as shown in FIG.
It is urged toward.

When the leg (3) is turned upright from the folded position, the lock pin engaged in the elongated hole (9) reaches the large-diameter hole (10). 7) elastically swings outward, the large-diameter head (8b) of the lock pin (8) automatically engages with the large-diameter hole (10), and stands the leg (3). Lock to state. To release the lock and fold the legs, push the slide lock plate (7) against the elasticity to
0) into the small diameter portion (8a) of the lock pin (8), and
Along with the lock pin (8). By sliding the lock pin (8) along the slot (9), the leg (3) can be folded.

[0011]

According to the present invention, the folding leg of the furniture can be locked in the standing position only by the operation of standing up from the folding position, and the movement of the folding leg to the standing position and the locking can be performed in one operation. Becomes possible,
Even when shifting from the standing position to the folding position, the slide lock plate can be unlocked and moved to the folding position only by pushing in against the elasticity, providing a folding leg for furniture that is extremely simple and easy to handle. It is possible to do.
