て活用することが出来ない。(Prior Art and its Problems) In a conventional hinge of this type, both ends of a leaf spring curved into an arc are pivotally connected to a pair of mounting plates on the hinge. In such a conventional hinge, if the leaf spring is sized to maintain a curved state that can efficiently bias both mounting plates in the opening direction when both mounting plates are unfolded at 180 degrees, When the mounting plate is moved to close, the leaf spring is pinched by both the mounting plates, and it is impossible to close the mounting plates to a state where they are parallel to each other and face each other. In order to make this possible, large notches must be provided in both mounting plates into which the leaf springs fit loosely, which reduces the strength and makes it impossible to use the hinges as furniture hinges.

に於いて保持される。 In the hinge configured as described above, when both the mounting plates 1 and 2 are opened at 180 degrees as shown in FIGS. 1 and 3, the distance between the leaf spring pivot shafts 10 and 11 is the maximum Therefore, both legs 14b and 14c of the leaf spring 14 are opened against the elasticity, and the return elastic force is applied to the pivot shafts of both leaf springs at an intermediate position between the support shaft 7 and the mounting plates 1 and 2. It acts in the direction of bringing 10 and 11 closer together. For this reason, both mounting plates 12
Since a biasing force 15 in the opening direction is applied around the support shaft 7, both mounting plates 1 and 2 are held at the opening restriction position.

位置となる。 The hinge held in the unfolded state can close both the mounting plates 1 and 2 about the support shaft 7 against the biasing force 15 in the opening direction of the leaf spring 14. At this time, when the imaginary line connecting both leaf spring pivot shafts 10 and 11 crosses the support shaft 7 from the side where the mounting plates 1 and 2 are located to the opposite side, both legs 14 of the leaf spring 14
The return elastic force acting on b and 14c acts in the direction of closing both mounting plates 1 and 2 around the support shaft 7. That is, the opening biasing force 15 of the leaf spring 14 is switched to the closing biasing force 16 as shown in FIG. 4, and both mounting plates 1 and 2 are automatically closed by the closing biasing force 16. and is held in the closed movement limited position. FIG. 4 shows the state immediately before reaching the closing movement limit position, that is, the state where both mounting plates 12
shows a state in which they are parallel to each other and facing each other. In the illustrated structure, the position where both the mounting plates 1 and 2 come into contact with both ends of the portion 14a corresponding to the bottom of the leaf spring is the closing movement restriction position.

付勢することが出来る。(Operations and Effects of the Invention) As is clear from the above embodiments, according to the hinge of the present invention, the pair of mounting plates can be elastically held in the expanded state and the closed state by the leaf springs. In addition, opening and closing can be performed automatically by biasing both mounting plates in the opening direction or the closing direction with respect to the neutral point. In addition, the leaf springs used are not curved in an arc shape as in the past, but are bent in a triangular shape, so the bottom part is a narrow space between the two mounting plates in the closed state facing each other parallel to each other. Even though the width fits within the space, both legs are given a necessary and sufficient length, so that even when both mounting plates are in the expanded state, both mounting plates are efficiently biased in the opening direction by both legs of the leaf spring. You can.

はなく、強度的にも問題のない蝶番が得られる。 In other words, the leaf spring pivot shaft is located at a relatively distant position from the support shafts for both mounting plates, and the degree of deformation of the leaf spring while both mounting plates open from the closed state to the unfolded state is measured. It is possible to increase the size of the mounting plate and to securely and strongly hold both mounting plates in the closed state and the unfolded state. Of course, there is no need to provide notches in both mounting plates into which the leaf springs fit loosely, and a hinge with no problem in strength can be obtained.
