Embodiment Construction

[0023] Next, an embodiment of the present invention will be described with reference to the drawings. like Figure 1 ~ Figure 3 As shown, the door 2 (the other object) is rotatably supported via the hinge device 5 of the present invention at the side edge portion (part of the peripheral portion forming the opening 1x) of the opening 1x of the furniture body 1 (one object). Open and close the opening 1x with the door 2 at the side edge.

[0024] like Figure 1 ~ Figure 4 As shown, the above-mentioned hinge device 5 has: a first body 10 installed on the furniture body 1; a second body 20 installed on the door 2; Links 30, 40. These first and second bodies 10 and 20 and the first and second chain links 30 and 40 constitute a four-link mechanism.

[0025] Above-mentioned first main body 10, in the front and rear direction of furniture body 1 ( Figure 1 ~ Figure 3 It is formed elongatedly in the left-right direction), has a main wall 11 and a pair of side walls 12, and has a ...

Abstract

A hinge device (5), which has: an elongated first body (10) mounted on a furniture body, etc.; a cover-shaped second body (20) mounted on a door; the second body (20) ) rotatably connected to the first and second links (30), (40) on the first body (10); and a torsion spring (70). One end (70a) of the torsion spring (70) pushes the spring receiving plate (32a) of the first link (30), thereby turning the second main body (20) toward the first main body (10). force. One end (70a) of the torsion spring (70) is disposed between the side wall (12) of the first body (10) and the side wall (42) of the second link (40). The gap between the spring receiving plate portion (32a) and the side wall (12) of the first main body (10) and the gap between the spring receiving plate portion (32a) and the side wall (42) of the second chain link (40) are all larger than One end (70a) of the torsion spring (70) has a small line width.

Description

technical field [0001] The present invention relates to a hinge device suitable for rotatably connecting another object such as a door with respect to an object such as a box having an opening or a furniture body. Background technique [0002] Such a hinge device is disclosed in Japanese Unexamined Patent Publication No. 7-10339. The hinge device has: a U-shaped first body with an elongated section mounted on the side edge of the opening of the furniture body; a cover-shaped second body mounted on the side edge of the door; and the second body is rotatable. The first and second chain links (links) of the first main body are ground-connected. These first and second main bodies and the above-mentioned first and second chain links constitute a four-section chain link mechanism. [0003] In the closed state, the door is in contact with the front surface of the opening peripheral portion of the furniture body over the entire circumference. When the door is turned in the openin...
