6 into the engagement hole 17 of the other divided body 15,
The rotating body 2 is constructed by joining both the divided bodies 14 and 15, and the rotating body 2 is connected to the base 1 so as to be rotatably openable and closable.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In this hinge, a base 1 and a rotating body 2 are rotatably connected by a rotatable first link arm 3 and a second link arm 4, and the base 1 is connected to a main body 5 of furniture or the like. At the same time, the rotating body 2 is attached to the door 6 side of furniture etc., and the door 6 is attached to the main body 5.
It can be opened and closed freely.

The base body 1 is integrally formed of synthetic resin and has a substantially U-shaped cross section, and has plate-shaped attachment portions 11 protruding from both sides of its lower surface to be joined to a body 5 such as furniture. Furthermore, a pair of first bearing holes 12 are formed on both side surfaces of one end of the base body 1 .

The rotating body 2 is integrally formed of synthetic resin, and is constructed by joining a substantially symmetrical first divided body 14 and second divided body 15 that are rotatably connected via a thin hinge portion 13. ing. In addition, the first
An engaging protrusion 16 is formed on the mating surface of the divided body 14, and an engaging hole 17 is formed on the mating surface of the second divided body 15. By engaging the holes 17, both the divided bodies 14 and 15 are held in a joined state. Further, a recess 18 with one side open is formed in the rotary body 2, and plate-shaped mounting portions 19 are protruded from both sides of the opening side of the recess 18. Furthermore, the recess 1
A second bearing hole 20 and a third bearing hole 21 are formed in pairs on both sides of the shaft 8, that is, in each of the divided bodies 14 and 15. The rotating body 2 is embedded in a door 6 of furniture or the like, and is attached to the door 6 by joining a mounting portion 19 to the door 6.

The first link arm 3 is integrally provided at one end of the base 1 via a thin hinge portion 22 that allows the first link arm 3 to rotate. Further, a pair of first shafts 23 are formed on both sides of the distal end of the first link arm 3, and are rotatably fitted into the second bearing hole 20 of the rotating body 2.

The second link arm 4 is formed of a metal plate, synthetic resin, etc., and the base 1 is attached to both sides of its base end.
A pair of second shafts 24 are formed to be rotatably fitted into the first bearing holes 12 of the rotating body 2, and the third bearing holes 2 of the rotary body 2 are formed on both sides of the tip thereof.
A pair of third shafts 25 are formed to be rotatably fitted to the shafts 1 .

Next, the assembly method will be explained.

First, push open both sides of the base body 1, fit the second shaft 24 of the second link arm 4 into the first bearing hole 12 of the base body 1, and attach the second link arm 4 to the base body 1. Install so that it can rotate freely.

Next, the first and second divided bodies 14 and 15 are rotated from the thin hinge part 13, and both divided bodies 14,
15 engaging protrusions 16 and engaging holes 17 to join both the divided bodies 14 and 15 to form the rotating body 2. During the rotation operation, the first link arm 3 Shaft 23 and second link arm 4
and the third shaft 25 of the rotating body 2,
0 and the second bearing hole 21, respectively.

In this way, both link arms 3 and 4 are rotatably attached to the rotary body 2, and the rotary body 2 is connected to the base 1 so as to be rotatably openable and closable.

According to the above configuration, the hinge is composed of only three parts: the base body 1 integrally provided with the first link arm 3, the rotating body 2, and the second link arm 4, and the structure is also simple. Because I'm getting used to it,
It is possible to provide an inexpensive hinge, and as described above, it is easy to assemble.

[Effect of idea]

According to the present invention, the second shaft of the second link arm is fitted into the first bearing hole of the base body integrally provided with the first link arm, thereby forming a pair of integrally connected divided bodies. When joining to form a rotating body, the first axis of the first link arm and the third axis of the second link arm are connected to the second bearing hole of the rotating body and the third axis of the second link arm.
Since the hinge is fitted into the bearing hole of the hinge, the number of parts can be reduced to three, the structure can be simplified, and as mentioned above, assembly can be facilitated, and an inexpensive hinge can be provided.
