Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a system in which a cup-shaped mounting member fixed to a door of furniture, etc., and a frame-shaped mounting member fixed to a main body frame are rotatable by multiple links. The present invention relates to a concealed hinge that is connected to the two mounting members, and more particularly to a hinge with a catch mechanism that operates in the closed position of both mounting members.

[Prior Art] Various hinges of this type have been provided in the past, but the general catch mechanism has been installed inside the frame of a frame-type mounting member. For this reason, the upper surface of the frame is raised high, and particularly the spring mounting area is protruded.

[Problems to be Solved by the Invention] If the frame-type mounting member is fixed to the end surface of the main body frame as it is, the top surface of the frame will come into contact with the inside of the door just before the door is closed, making it impossible to close the door. Become. To solve this problem, Japanese Utility Model Publication No. 58-5827 proposes a structure in which an expanded portion is formed in the width direction of the end face of the main body frame, although it does not include a catch mechanism.

However, in this case, it was necessary to prepare two extension parts, one for the top and the bottom and one for the base plate, with opposing extensions, and there was no space to install a catch mechanism.

Furthermore, when the frame type mounting member is fixed inside the main body frame, there is a drawback that the amount of protrusion from the inside of the frame is large, which becomes an obstacle to storage, internal partitioning, etc.

The present invention has been further developed in view of the above-mentioned circumstances, and by arranging the catch mechanism on the fixed side of the frame-type mounting member, it is possible to catch furniture of various types and sizes. Its purpose is to allow a mechanism to be attached.

[Structure of the Invention] The structure of the hinge with a catch mechanism according to the present invention for solving the above object includes a frame-type mounting member fixed to the main body frame, and a frame-type mounting member fixed to the door when the door is closed. A hinge comprising a cup-shaped mounting member capable of accommodating a frame-shaped mounting member, multiple links rotatably connecting each member, and a catch mechanism that is activated when the door is closed. is projected toward the fixed side, and a catch mechanism is housed within the projection.

[Operation of the invention] A cup-shaped mounting member is embedded into a mounting hole provided on the back side of the door, and a frame-shaped mounting member is mounted and fixed at a predetermined position on the main body frame. In this case, since the catch mechanism protrudes toward the fixed side, the protrusion may be accommodated in the mounting surface of the main body frame.
