Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table in which legs provided on the lower surface of a top plate are switchable between a standing position and a folding position along the lower surface of the top plate via a connecting tool. .

[0002]

2. Description of the Related Art In this type of table, it is desired that the height of the table can be changed in a plurality of steps according to the usage pattern. It is desired that the table can be used as a low table in which a slight gap is formed between the lower surface of the and the installation surface such as the floor surface. In response to such a demand, conventionally, as shown in FIG. 7, a hinge-shaped connecting tool 04 attached to the lower end surface of the fixed leg 02 fixed to each of the four corners of the lower surface of the top plate 01 is provided. Through the legs 03
Is configured so that it can be switched from a standing posture to a folding posture along the lower surface of the top plate and can be held in the folding posture, and the lower surface 03A of the leg 03 in the folding posture is a ground contact surface at the time of low table. Was.

[0003]

In this conventional table, the table height can be changed in two steps by switching the posture of the legs 03, but when used as a low table, the legs 03 in the folding posture are used. The lower surface 03A of the table is easily scratched by dragging or the like, and when such a scratch occurs, the scratch appears on the lateral outer surface of the table when the legs 03 are switched to the standing posture, which causes a problem of impairing the appearance of the table. Moreover, when the tip of the leg 03 in the folded posture is placed on a magazine or the like on the installation surface G when used as a low table, a large moment acts on the coupling tool 04, so that this large Must be strong enough to withstand the moment
It has been a factor that causes a rise in manufacturing costs. The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to change the table height to three levels by devising the structure of the connecting tool and the legs, and moreover, the low table. It is possible to provide a table capable of suppressing damage to the lateral side surface of the leg during use as a table, and simplifying the attachment structure including the connecting tool and reducing the manufacturing cost.

[0004]

A characteristic configuration of the present invention for achieving the above object is to connect a leg to a lower surface of a top plate so as to be switchable between an upright position and a folding position along the lower surface of the top plate. A connecting leg is provided, and a joint leg longer than the height from the lower surface of the top plate to the lower surface of the leg in the folded position can be selectively replaced with respect to the lower end surface of the leg and the lower surface of the top plate. In addition, when the joint leg is attached to the lower surface of the top plate, a concave portion is formed that fits vertically from a protrusion provided on a fixing member on the top plate side of the connector. It is in.

A recess may be formed in the leg so that the leg fits into the projection of the connector when the leg is switched from the folded posture to the standing posture.

[0006]

According to the structure of claim 1, when used as a low table, since the joint leg longer than the height from the lower surface of the top plate to the lower surface of the leg in the folded position is used as the leg of the low table, Even if the lower surface of the leg in the folded posture from the lower surface of the top plate does not come into contact with the floor surface, and a horizontal external force acts on the top plate or joint leg, a part of the external force is
It can be received by the fitting portion between the projection of the connector and the recess of the joint leg. In addition, the height of the table in which the legs are in the standing posture can be changed by attaching and detaching the joint legs.

According to the second aspect of the present invention, when the leg is switched to the standing posture and used, even if an external force in the horizontal direction acts on the top plate or the leg, a part of the external force is applied to the connector. It can be received at the fitting portion of the projection and the recess of the leg.

[0008]

According to the table of the first aspect, not only can the table height be changed to three levels, but also when used as a low table, scratches on the lateral sides of the legs can be suppressed, and Even if the joint leg is placed on a magazine etc. on the installation surface, a large moment does not occur as in the past, and a part of horizontal external force is not used. Since it can be received by the tool, the mounting structure including the connecting tool can be simplified and the manufacturing cost can be reduced.

The table according to claim 2 has a durability because it is possible to receive a part of the external force from the horizontal direction by utilizing the projection of the connecting tool even when the table is used in which the legs are switched to the standing posture. The superior leg mounting structure can be advantageously constructed in terms of manufacturing and manufacturing costs.
