[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, a door holding member having a complicated structure and a driving member (for example, a pulley, a belt, a rack, a pinion, etc.) for driving the door holding member are required, and further, opening and closing of the door is required. Since the support shaft that supports the vehicle, which replaces the hinge, supports the entire door, there was a problem in terms of strength with a support shaft that could be used in a limited space in the door. Further, when the hinge uses a link mechanism, and when the door is opened from the furniture body, the engagement hole formed in the furniture body has to be large. However, after the door is pulled out forward, a gap is created between the engagement hole and the hinge. If this gap is not closed, there is a problem that fingers may be caught and injury may occur. In view of these circumstances, the present invention combines a base plate, a cam plate, and a link assembly member, which are made of a plate material that is also strong in terms of strength, with a simple structure, and further sandwiches the cam plate of the link assembly member. Protrusions are provided on the sides of the L-shaped upper third arm and the substantially L-shaped lower third arm so that when the door is opened, the engagement hole provided at the front of the furniture body can be closed. The purpose of the present invention is to provide a hinge for a door in furniture or the like that can smoothly open and close the door, can open a sufficient degree, and can close the gap, thereby eliminating the risk of pinching a finger. To do.

[Effect of device]

 The present invention can obtain the following effects based on the above configuration. (1) Since a hinge is used for the link mechanism, it is necessary to increase the size of the engagement hole formed in the front part of the furniture body. For this reason, it is necessary to keep the door open until it is opened 180 °. A gap may be formed between the engagement hole and the upper and lower third arms of the substantially L shape, and a finger or the like may be caught in this gap. For this reason, since the door is pulled out to the front and opened 180 degrees, the protrusions that close this gap are formed on the upper and lower third arms of the substantially L-shape so that there is no risk of pinching a finger or the like. (2) By combining the base plate, the link assembly member, and the cam plate, the opening of the door can be opened 90 degrees or 180 degrees without being restricted by the door of the adjacent furniture. (3) Since the caulking shaft provided with the rotating collar is used for sliding while rotating in the cam groove of the cam plate, the door can be rotated extremely smoothly. (4) Since it is not necessary to cut the corners of the door to which the hinge is attached, the appearance is extremely clean. (5) There is no problem in opening and closing the door even when the storages of different heights are arranged in parallel. (6) Since the link member and the cam are formed from the plate material, it is most suitable as a hinge, and also sufficiently functions as a support for a heavy door in terms of strength.
