Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support frame fixing metal fitting fixed to a support frame and a door fixing metal fitting fixed to a door by making the metal fitting and the metal fitting of the door fixing metal fitting detachable. The present invention relates to a hinge device that can be detached and can efficiently perform a door replacement operation without lowering the mounting strength.

[0002]

2. Description of the Related Art For example, as shown in FIG. 14, a door b having a side edge b1 flush with the side surface a1 of the support frame a is provided at the outer end of the parallel support frames a and a. When the hinge c is attached to the edge b1 so as to be openable and closable, the door b is opened in a state of protruding from the side surface a1 of the support frame a as shown by the alternate long and short dash line in FIG. The side edge b1 of the door b may collide with furniture or the like arranged adjacent to the frame a.

On the other hand, as shown in FIG. 15, when hinges c are nailed to the outer end surfaces a2 of the parallel supporting frames a and a and the side edge b1 of the door b, the door b is one point in FIG. As shown by the chain line, the side edge b1 faces the outer end surface a2 and is opened,
Although the above-mentioned inconvenience does not occur, in such a case, the door b
When the door is closed, there is a problem in that a step is formed between the outer end surface a2 and the outer surface of the door b, which deteriorates the appearance.

A so-called slide hinge is used to solve such a problem. The slide hinge s is shown in Fig. 1.
6, as shown in FIG. 17, the support frame fixing metal fitting d is screwed to the inner surface and near the outer end of the support frame a, and the recess e1 is fixed to the door b with wood screws or the like and is embedded in the door b. The door fixing bracket e, and two links f and g each end of which is connected to the supporting frame fixing bracket d and the door fixing bracket e, respectively.
By forming a so-called four-bar linkage mechanism with the two links f and g, the links f and g sink into the recess e1 in the closed state of the door b shown in FIG. Is abutted against the outer end surface a2 of the support frame a to dispose the door b, and in the opened state of the door b shown in FIG. 16, the side edge b1 of the door b is aligned with the outer end surface a2 to open the door b. Is
This can solve the above-mentioned problems.

[0005]

However, in such a slide hinge s, since the door fixing metal fitting e is attached to the door b by a wood screw, it is easy to change only the door due to a specification change or the like. Moreover, if the door is repeatedly attached and detached, the screwing force of the wood screw may decrease and the mounting strength may be impaired.

The present invention is based on the fact that the metal fittings of the door fixing metal fittings to which the support frame fixing metal fittings are attached via the links and the metal fittings of the door fixing metal fittings fixed to the door can be engaged and disengaged. It is an object of the present invention to provide a hinge device that can easily separate the frame fixing bracket and the door and can efficiently perform the door replacement work.
