Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to furniture such as a table provided with folding legs.

[0002]

2. Description of the Related Art Conventionally, for example, as a table having foldable legs, legs are supported on a lower surface of a top plate via a hinge mechanism, and a folding position substantially parallel to the lower surface of the top plate and a furniture body are supported. 2. Description of the Related Art There is known a device configured to be able to rotate between a use position to be obtained.

By the way, in this type of table, FIG.
As shown schematically, the leg 102 is made of a square pipe material or the like, and the center of rotation C of the leg 102 with respect to the top plate 103 is set at the folding position Q at the lower surface 10 of the top plate 103.
In general, the inner surface 102a of the leg 102 facing the base plate 3a and the outer surface 102b of the leg 102 which is opposite to the top plate 103 at the folding position Q are set on the leg axis n which is equidistant from the leg 102. It is.

[0004]

However, in such a configuration, unless the base end of the leg 102 pivotally supported by the hinge mechanism 104 is processed into a special shape, the leg 102 is not folded at the folding position Q. There is a problem that it is difficult to approach the top plate 103 and it becomes bulky when a large number of sheets are stacked and stored.

That is, when the base end of the leg 102 manufactured by cutting the square pipe material is supported by the axis 111 of the hinge mechanism 104 at the base axis n, the base end face 102c of the leg 102 is The inner corner portion 102d that intersects with the side surface 102a draws a locus farthest from the rotation center C of the leg 102 on the top plate 103 side. for that reason,
When the position of the shaft 111 is set so that the inner corner portion 102d does not interfere with the lower surface 103a on the top plate 103 side or the upper surface of the hinge mechanism 4 when rotating, the top plate 103 and the leg 102 are compared at the folding position Q. This results in a certain limit in reducing the thickness of the entire table.

In order to solve such a problem, the position of the shaft 111 is set closer to the inner side surface 102a than the leg axis n, and the rotation center C of the leg 102 is
It is conceivable to approach 2d as closely as possible. That is,
This makes it possible to reduce the radius of the rotation locus of the inner corner portion 102d when the legs are folded, so that the shaft 111 can be brought closer to the top plate 103. As a result, the inner side surface 102a of the leg 102 can be easily brought closer to the top plate 103 at the folding position Q, and the thickness of the table in the folded state can be reduced.

[0007] However, with just this,
As shown in FIG. 14, a problem occurs when the cover 106 that surrounds the outside of the hinge mechanism 104 is provided on the top plate 103 side. That is, according to such a configuration, the rotation locus of the outer corner portion 102e where the base end surface 102c and the outer surface 102b of the leg 102 intersect becomes large. Therefore, the base end surface 102c of the folded leg 102
Unless a large gap S is formed between the inner cover 106 and the inner surface 106a of the cover 106, the rotation of the leg 102 becomes impossible. In other words, the gap S formed between the leg 102 and the cover 106 fluctuates greatly with the rotation of the leg 102, and when a finger is inserted into the gap S and operated, the finger may be pinched. .

[0008]

According to the present invention, the center of rotation of the leg with respect to the furniture main body is set on the inner side of the leg axis center line of the leg, and the folded leg approaches the lower surface of the furniture main body. In addition to providing the protrusion, at least one of the facing members such as the leg and the cover is provided with a protrusion facing the gap, and the size and the position of the protrusion do not inhibit the rotation of the leg. And it is set so that at least a human finger can be prevented from being inserted into the gap.

[0009]

To achieve the object of the present invention without increasing the number of machining steps,
It is preferable that the leg comprises a pipe-shaped leg main body and a cap attached to an end face of the leg main body, and the cap constitutes a base end of the leg. in this case,
It is particularly desirable to form the leg side projection integrally with the cap.

In order to promote stabilization of the leg in the use state, a portion of the base near the outer surface at the base end is brought into contact with a downward surface provided on the furniture body side at the use position, and the leg is attached. It is better to lock. In this case, the tip surface of the cap is inclined such that the outer surface side edge of the tip surface of the cap is more separated from the center of rotation of the leg than the inner surface side edge, and the tip surface of the cap is In order to reduce the gap, it is particularly desirable to make the outer side edge portion contact the downward facing surface provided on the furniture body side.

A typical example of the furniture body includes a table top plate and a hinge mechanism for supporting legs provided on the lower surface of the table top. An example of the facing member is a cover of the hinge mechanism. The invention according to claim 9 is configured such that the legs provided on the furniture main body can be rotated between a predetermined folding position and a use position capable of supporting the furniture main body, In furniture in which a gap formed between the leg and a facing member provided on the furniture body side fluctuates with rotation of the leg, the leg-side protrusion provided on the leg and the facing surface The main body-side projection provided on the member is arranged so that at least a human finger can be prevented from being inserted into the gap, and the leg-side projection and the body-side projection are at least arranged. It is characterized in that it is configured to engage with each other while the legs are rotating so that they can move relative to each other. However, in the present invention, it is not an essential requirement that the center of rotation of the leg exists closer to the inner side than the axis of the leg.
