A rotating body is rotatably connected via a link arm of the book, and a guide passage is formed through the receiving casing integrally formed in the rotating body facing in the direction opposite to the base body, and is engaged with the guide passage. A coil spring is slidably fitted into the guide shaft of the stop member and housed in a hollow chamber within the guide shaft.
Both ends of the locking pin fixed to the receiving casing and passed through the elongated hole of the guide shaft are supported between the inner end face of the hollow chamber, and the coil spring urges the locking member toward the base body to engage the locking pin. By press-contacting the locking curved portion formed in the hook-shaped portion of the locking member to the base-side end of one of the link arms so that the receiving casing can be moved toward and away from the rotating body, the rotating body can only be held in the closed state. The hinge that holds it is described. The coil spring acts on the link arm with a constant tension.

がある。(Problem that the invention aims to solve) However, it is desirable to set the force with which the door of this furniture is held in the open/closed state and the load during the opening/closing operation, depending on conditions such as the size of the furniture in which the hinge is used. However, the above-mentioned first conventional technology and Japanese Patent Application Laid-Open No. 1987-
In the conventional hinge described in Publication No. 51448,
Since the tension of the spring is set constant, the force for holding the rotating body in the open/closed state is also set constant, and there is a problem in that it cannot be adjusted. Furthermore, in the structure of JP-A No. 49-51448, when the rotating body is closed, the locking curved portion of the receiving casing that does not rotate is attached to the end of one link arm on the base body side. In the structure of Publication No. 58-118167, when the rotating body is opened and closed, the engaging rod of the rotating body rotates while sliding on the cam of the engaging body, so in each structure, the sliding resistance is large and the rotating body cannot be moved smoothly. It cannot be rotated to open and close, and each sliding part is easily worn out.Furthermore, the structure of Japanese Utility Model Application Publication No. 58-118167 allows the tension of the coil spring to be adjusted, but the structure of this publication and Japanese Patent Publication No. 49-51448
The structure disclosed in the above publication has problems in that it has a large number of parts, is complex, has poor assembly workability, and has an overall large size, which is one of the causes of increased costs. In addition, when a leaf spring is used as a spring to bias the link arm, the cam part of the link arm slides on the leaf spring, which causes problems such as localized wear on the leaf spring. .

It can be easily adjusted and set in response to changes in the load during operation, the rotating body rotates open and close smoothly, there is no wear, the structure is simple with a small number of parts, and it is easy to assemble. It is an object of the present invention to provide a hinge that can be formed compactly in overall form and that can reduce costs.

の開閉動作時の荷重を調整することができる。 At that time, by rotating the adjusting screw 24 to adjust the forward and backward movement, the coil spring 23 held between the adjusting screw 24 and the ball receiver 22 is expanded and contracted, and its tension is changed. Therefore, the force that biases the second link arm 4 through the ball receiver 22 and the ball 21 is variably adjusted. The force that urges the second link arm 4 can be changed, and the force that holds the rotating body 2 in the open/closed state and the force that urges the rotating body 2 can be changed.
The load during opening and closing operations can be adjusted.

ることはない。 The coil spring 23, which is adjusted and set by the adjustment screw 24, is connected to the cam portion 2 of the second link arm 4 via the ball receiver 22 and the ball 21.
Since the coil spring 23 is biased at 0, even if the rotating body 2 is repeatedly opened and closed, the coil spring 23 will not be worn out.

して行なわれる。 By the way, if the coil spring 23 were brought into direct contact with the ball 21, the coil spring 23 would be caught between the circumferential surface of the through hole 12 and the ball 21, and the coil spring 23 would be caught or opened. However, as mentioned above, the ball receiver 22 is interposed between the ball 21 and the coil spring 23, and the main body of the ball receiver 22 is By fitting one end of the coil spring 23 into the spring fitting part 26 of 25, the coil spring 23 will not be caught, and its expansion and contraction will be performed smoothly and stably.

ものでよい。 Further, since the ball 21 is always rotatably supported in close contact with the concave ball receiving portion 27 of the ball receiving body 22, the ball receiving portion 27 of the ball receiving body 22 is deformed by the pressure of the ball 21. This will be prevented. Further, since the ball 21 is rotated by the cam portion 20 of the link arm 4, it is desirable that the ball 21 have high rigidity to prevent wear, but the ball receiver 22 may have a lower rigidity. .

よいので、容易に形成することができる。 By the way, it is also conceivable that the ball 21 and the ball receiver 22 be made integrally. However, in this case, a member having a complicated shape must be made of a hard material, resulting in poor manufacturability. However, according to the above configuration, since the ball 21 and the ball receiver 22 are made separate, the ball 21 must be hard, but since it is spherical,
It is relatively easy to process, and on the other hand, the ball receiver 22
Although it has a complicated shape, it can be easily formed because the material is soft.

Since the link arm 4 is always brought into contact with the cam portion 20 at the end of the link arm 4 on the base body 1 side, the rotating body 2 can be held not only in the closed state but also in the open state.

According to the present invention, in the through hole of the base body, there is provided a ball that is always in contact with the cam part of the second link arm that connects the base body and the rotating body, and a ball receiver that tightly supports the ball so as to be rotatable at all times. The body and a coil spring that presses and supports this ball receiver are sequentially slidably fitted, and an adjustment screw that presses and supports the coil spring with the ball receiver is screwed into the through hole so that it can be adjusted forward and backward. Therefore, by adjusting the adjustment screw forward and backward, the tension of the coil spring that urges the ball toward the cam part of the second link arm can be directly and easily adjusted, thereby increasing the holding force of the rotating body in the open and closed state. Adjustment settings can be easily made in response to changes in load during opening and closing operations. In addition, a concave ball receiving part is formed on the ball receiving body that is biased by a coil spring, and the ball that is always in contact with the cam part of the second link arm is rotatably attached to this ball receiving part. Therefore, when the rotating body rotates to open and close, the ball rotates while allowing the cam portion of the second link arm to smoothly move. There is no high sliding resistance or wear between the ball and the cam part, and since the ball is supported and rotated by the concave ball receiving part, even if the ball is pushed by the cam part, The ball receiving portion is not deformed by the ball. Also, since one end of the coil spring was fitted into the spring fitting part of the ball receiver,
One end of the coil spring can be supported reliably, and
The coil spring expands and contracts smoothly and stably. Furthermore, a through hole was formed in the base body facing the cam part, and the ball, ball receiver, and coil spring were sequentially and slidably fitted into this through hole toward the cam part. Compared to the structure, the number of parts is small, the structure is simple, the assembly workability is excellent, the overall form can be formed compactly, and costs can be reduced.
