Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a hanging hook used when hanging a decoration from the tip of a support arm.

[Conventional technology]

A hook from which decorations such as small toys can be freely hung may be formed integrally with the tip of a support arm set upright on a base, or may be made separately and fixed to the tip of the support arm. is generally used.

[Problem that the invention attempts to solve]

Since conventional hanging hooks are fixed to the support arm, it may not be possible to hang the decoration by changing the orientation of the decoration due to the latch attached to the decoration, so the decoration can only be hung in one direction at all times. It is uninteresting to be hung facing the direction of the camera, and also, due to the space (depth) between the support arm installed on the base and the hook installed at the tip of the support arm, it is difficult to hang it. There is a problem in that the size of decorations that can be lowered is limited by itself.

[Means to solve the problem]

The present invention solves the above-mentioned problems, and its purpose is to be able to be detachably attached to the tip of a support arm, and to make the hook body from which the decoration is hung be To provide a new hanging hook which can be dynamically rotated and is convenient for hanging decorations. Therefore, the above object of the present invention is to form a circular concave portion on the upper surface side,
and a hollow cylindrical support body with an insertion edge protruding from the outer peripheral side of the concave surface portion, and a hook body that is inserted from the lower part of the support body and rotatably supported by the support body, A center hole is formed in the concave surface of the support, and a locking protrusion is provided on the concave surface;
The hook body has a coil spring wound around a shaft connected to the upper end of the hook, and is inserted into the support body via the shaft, and the shaft is connected to the center of the concave surface. A coupling plate protruding from the hole onto the concave part and loosely fitted onto the concave part is fixed to the shaft part, and a recess provided on the lower surface of the coupling plate is connected to a locking protrusion on the concave part. This is achieved by means of hanging hooks that are releasably engaged.

【Example】

Embodiments of the present invention will be described below with reference to the accompanying drawings. This hanging hook consists of a support body 1 and a hook body 7 rotatably attached to the support body 1, both of which are made of synthetic resin. The support body 1 has a hollow cylindrical shape with a circular concave portion 2 on the upper surface side, and an outer peripheral side portion 2 of the concave portion 2.
Insertion edges 3, 3 which can be freely inserted into the tip of the support arm to be described later are provided on the opposite left and right sides of a.
However, there are also protruding pieces 4 located between the two insertion edges 3, 3 that project to the left and right, and a center hole 5 is bored on the concave surface portion 2.
On the diameter extension line of this center hole 5, there are two
The locking protrusions 6, 6 are provided. On the other hand, a shaft portion 8 that is inserted into the support body 1 is connected to the hook body 7, and the root portion of this shaft portion 8 is formed into a flange portion 9 large enough to fit loosely into the support body 1. There is. Therefore, in order to insert the hook body 7 into the support body 1, the coil spring 11 is first wound around the shaft portion 8, and the shaft portion 8 is inserted into the support body 1 so that the hook body 7 is inserted above the concave surface portion 2 through the center hole 5. A separately provided connecting plate 12 is loosely fitted onto the concave portion 2, and the connecting plate 12 is fixed to the upper end of the shaft portion 8 using screws 14, and the lower surface of the connecting plate 12 is fixed to the upper end of the shaft portion 8. The provided recesses 13 (in the illustrated case, four are provided at equal intervals) are removably engaged with the locking protrusions 6, 6 provided on the concave surface portion 2, and the support member 1 and hook 7
It is connected to allow relative rotation. In addition,
The upper end surface of the shaft portion 8 is chamfered into a substantially oval shape, and a recess 12a having a shape corresponding to the chamfer 8a is provided in the coupling plate 12. By fitting the chamfered portion 8a and the recess 12a, the shaft portion 8 and the joint plate are connected. It has a structure that does not allow relative rotation between it and 12. In the figure, 8b is a screw hole, and 12b is a screw insertion hole.

[Effect]

According to the above configuration, as shown in FIGS. 4 and 5, the insertion edges 3, 3
If it is inserted into the insertion grooves 16, 16 formed in 5a,
This hanging hook can be attached to the support arm 15, and the overhanging piece 4 of the support body 1 functions as a stopper during the insertion operation, and the attachment state is fixed, and the hook body 7 is rotatable. Therefore, you can freely choose the direction and use it.

[Effect of the idea]

The present invention is as described above, and the state of connection between the support body and the hook body is stabilized by the spring action, and the rotation of the hook body is determined by the engagement and disengagement action between the locking protrusion and the recessed part. Because it is performed jointly at each angle,
This eliminates the problem of rattling during rotation or damage caused by excessive rotation, and the hook body can be reliably held in the desired rotation position, allowing the decorative body to be hung in the desired direction. becomes. Furthermore, it has the advantage of being easy to attach and detach from the support arm, and its practical value is extremely great.
