  By the way, the hanger hook described in Patent Document 1 has a feature that it is excellent in safety because the hook does not become an obstacle because the hook automatically returns to the case when not in use as described above. However, since the automatic return spring is exposed to the outside in a use state in which the hook is laid down, it is not possible to obtain a good use state.

  In addition, the spring that automatically returns the hook is a kick spring in which engagement pieces are provided at both ends of the coil portion in the tangential direction. Since the axial length of the kick spring is long, a kick spring provided in the hook is incorporated. Therefore, it is necessary to provide a large gap between the facing portions of the pair of ribs, and there is a problem that the width of the hook itself is increased and the hanger hook is enlarged.

  An object of the present invention is to provide a thin hook automatic return type hanger hook capable of obtaining an excellent usage state.

  In order to solve the above-described problems, in the present invention, a vertically long flat case embedded in a hook attachment target and a state in which the upper part is pulled out to the outside from a state accommodated in the front opening of the case. The hook is supported so as to be able to undulate, and a partition that divides the inner space into a hook accommodating space and a spring accommodating space located on the back side of the hook accommodating space is provided inside the case, A slit is provided on the back surface in the accommodated state, and a lower end portion of a flat thin-walled L-shaped spring guide is inserted into the slit so as to be rotatably connected to the hook by a connecting pin, and the position of the connecting pin is The upper part of the spring guide is inserted into a spring accommodating space through a slit formed at the lower end of the partition wall, and the spring accommodating space is inserted into the spring accommodating space. Than is adopted a structure incorporating a coil spring for urging downward the id.

  In the hanger hook configured as described above, when the lower end portion of the hook is pushed in, the hook is rotated outward to be inclined, and the inclined hook is further rotated toward the overturning direction. A suspended object such as clothing is supported by hanging the hook.

  In the use state of the hanger hook as described above, the coil spring is concealed by the partition wall, and only the lower end portion of the thin spring guide is exposed to the outside, so that a good use state of appearance can be obtained.

  Here, when the hook is pivoted toward the prone position, the connecting portion of the spring guide with respect to the hook pivots upward about the pivot central axis of the hook, and the spring guide is raised by the pivot. The coil spring is compressed and deformed.

  For this reason, when the suspended object is removed from the hook, the spring guide is pushed down by the restoring elasticity of the coil spring, the return rotational force is applied to the hook from the spring guide, and the hook automatically returns into the case.

  In the present invention, as described above, the partition is provided in the case, the inside of the case is partitioned into the hook accommodating space and the spring accommodating space, the coil spring is incorporated in the spring accommodating space, and the elastic force of the coil spring is thinned. Since it is applied to the hook via a thick spring guide to give the hook a restoring force for automatic return, the coil spring is concealed by the partition wall when the hook is in use, and only the lower end of the spring guide is external. It is possible to obtain a good state of use.

  In addition, since it is only necessary to form a slit into which a thin spring guide is inserted in the hook, a conventional hanger hook in which a pair of ribs is formed in the hook and a kick spring is incorporated between the pair of ribs is used. In comparison, the width of the hook can be reduced, and a thin hanger hook with a small width can be obtained.
