BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic hinge for mounting a joint concealing member that closes a gap in a meeting portion of a door such as furniture using a double-opening type.

[0002]

2. Description of the Related Art In recent years, a joint concealing member for closing a gap in a summing portion of a door is rotatably attached to a free end of one door by an auto hinge so that the door can be opened and closed by either the left or right door. .

That is, as shown in FIG. 3, the auto hinge 1
The base 2 of is attached inside the free end of one door 3,
The auto hinge body 4 is rotatably pivotally attached to the base 2 by a pivot pin (not shown), and is biased in an opening direction by a coil spring (not shown) attached to the pivot pin. The joint hiding member 5 is attached to the auto hinge body 4.

When the doors 3 and 6 are closed, the joint hiding member 5 abuts on the door catch 8 attached to the open end of the furniture main body 7 and resists the biasing force of the coil springs.
When the door 3 with the joint hiding member 5 attached thereto is opened, the joint hiding member 5 is made of a coil spring. The door 3 is rotated in the opening direction by the urging force so that the door 3 can be opened without hitting the other door 6.

[0005]

However, in the conventional auto hinge 1 , as shown in FIG. 4, the auto hinge main body 4 is formed as a single body, and is pivotally attached to the base by a pivot pin. Therefore, there is a problem that the mounting is difficult.

That is, the auto hinge 1 is normally attached to the open end side of the left door 3 near the center of the furniture main body 7, but if it is not attached correctly, the joint hiding member will be opened when the door 3 is opened. The joint hiding member 5 due to poor balance between the weight of No. 5 and the spring force of the auto hinge, insufficient tightening during assembly, etc.
May not be sufficiently opened, and the joint hiding member 5 may come into contact with the door 6 on the right side to damage the joint hiding member 5.
Also, if the furniture is distorted after being used for many years, the same problem may occur.

Further, in consideration of an error in attaching the doors 3 and 6 to the furniture main body 7, it is necessary to use a large door catch 8 in order to make it easy to receive the auto hinge 1. Therefore, the cost is increased. Not only that, but there is also the problem of poor appearance.

[0008]

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and when the left and right doors are opened and closed, even if the joint hiding member comes into contact with the right door, It is an object of the present invention to provide an automatic hinge that can be opened smoothly without damaging the joint hiding member.

In order to achieve the above-mentioned object, the auto hinge main body is constituted by a joint hiding member fixing portion for fixing the joint hiding member, and a hinge portion pivotally attached to a base attached to a free end of the door, The joint hiding member fixing portion is slidably fitted to the hinge portion in the left-right direction, and the joint hiding member is attached to the tip of the hinge portion by an elastic member interposed between the hinge portion and the joint hiding member fixing portion. It is designed to be biased in the direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to illustrated embodiments. 10 is a automatic hinge for attaching the joint hidden member closing the gap between the mating portion callings casement door (not shown.) Auto hinge body 11 and the automatic hinge body 11
And a base 12 for rotatably attaching to the door.

The auto hinge main body 11 is composed of a joint cover member fixing portion 13 for fixing the joint cover member, and a hinge portion 15 pivotally attached to the base 12 by a pivot pin 14 so as to be rotatable. Is designed to be biased in the opening direction by a spring 16 attached to the pivot pin 14.

A fitting recess 1 for fitting the joint concealing member fixing portion 13 is provided on the upper and lower edges of the hinge portion 15 from the substantially center to the front end side.
7 and 17 are formed, and the stepped portions at the tips of the fitting recesses 17 and 17 are used as stoppers 18 and 18 to prevent the joint hiding member fixing portion 13 from coming off.

Further, the hinge portion 15 is formed so that the joint cover member fixing portion 13 can be easily fitted into the hinge portion 15.
A slit 19 having an opening at the tip is formed at the center of the vertical direction.

Incidentally, the slit 19 may be formed at one central place as in the embodiment, or may be formed at two places near the upper and lower edges, and the forming place is not limited.

On the back surface side of the joint concealing member fixing portion 13, a fitting piece 2 fitted into the fitting recesses 17 of the hinge portion 15 is provided.
0 and 20 are formed.

Reference numeral 21 denotes a spring, which is an elastic member for urging the joint-hidden member fixing portion 13 toward the tip of the hinge portion 15. One end of the spring 21 is attached to the mounting portion 22 formed on the joint-hidden member fixing portion 13 and the other. The ends are attached to attachment portions 23 formed on the hinge portion 15, respectively.

As described above, according to the present invention, in the auto hinge in which the joint hiding member for closing the gap of the fitting portion of the door of the furniture etc. using the double-opening type is attached, the main body of the auto hinge is the joint hiding member. It comprises a joint hiding member fixing part to be fixed and a hinge part pivotally attached to a base attached to a free body of the door, and the joint hiding member fixing part is slidable in the left and right direction on the hinge part. Since the joint member is fitted and the joint member is fixed by the elastic member interposed between the hinge member and the joint member fixing portion , the joint member is attached. When the door on the side is opened or closed, even if the joint hidden member comes into contact with the edge of the other door, the joint hidden member moves to the base side against the biasing force of the elastic member, so that the door can be opened and closed smoothly. Because it is done, blindfold It was possible to prevent damage to the edges of the members and other doors.

Further, according to the present invention, since the joint hiding member is movable in the lateral direction, the magnet catch attached to the furniture main body can be made small, so that the cost of the magnet catch can be reduced. Not only that, the appearance can be improved.

Further, according to the present invention, since the slit and the stopper are formed in the hinge portion, the joint concealing member fixing portion can be easily assembled and prevented from coming off. Furthermore, the automatic hinge has an effect that it can be easily attached.
