Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of rotating a hook around a vertical axis with respect to a hanger body and at a plurality of rotational positions (a plurality of directions including a direction in which the hanger body is inclined with respect to a suspension rod). The present invention relates to a hanger hook mounting structure that is mounted in a state in which it can be held.

[0002]

2. Description of the Related Art Conventionally, as a hook mounting structure of this type,
The one disclosed in Japanese Utility Model Publication No. 3-16524 is known.

In this known technique, a round shaft-shaped mounting shaft is provided at the lower end of the hook, and the mounting shaft is fitted into a cylindrical body provided at the center of the hanger body to rotate the hook. And, it is attached so that it cannot move vertically.

Further, by providing a convex portion on one of the outer peripheral surface of the mounting shaft body and the inner peripheral surface of the cylindrical body, and by providing a plurality of concave portions on the other side, which are engaged with and disengaged from the convex portion by rotation of the hook, click A mechanism is configured so that the click shaft can hold the mounting shaft (hook) at a plurality of rotational positions.

According to this hook mounting structure with a click mechanism, when clothes are hung on a hanger and transported by a transportation vehicle, the hanger body is freely rotated due to vibrations or the like, and the clothes are rubbed against each other and the clothes are damaged. There is no fear.

Further, since the hanger can be hung on the suspension rod at an angle of, for example, 45 °, there is an advantage that the clothes displayed can be easily seen.

[0007]

However, according to the above-mentioned prior art, in reality, the cylindrical body hardly undergoes elastic deformation, and the outer peripheral surface of the mounting shaft body rubs against the inner peripheral surface of the cylindrical body. Since it rotates, the click part, especially the cylinder, is easily worn and plastically deformed.

Therefore, there is a drawback that the rotating operation is heavy at the beginning of use and the click action is lost early.

Accordingly, the present invention provides a hook mounting structure for a hanger which is light in rotation operation and can surely retain a click action for a long period of time.

[0010]

The invention according to claim 1 has the following construction.

(A) A mounting shaft is provided at the lower end of the hook.

(B) The mounting shaft body is provided with an elastic seat portion having an elastic force in the vertical direction at the upper portion and a locking flange portion at the lower portion so as to project to the outer peripheral side.

(C) A cylindrical body is provided at the hook mounting portion of the hanger body.

(D) At least one of the tubular body and the mounting shaft body is formed so as to be elastically deformable in the radial direction so as to allow passage of the locking flange portion with respect to the tubular body.

(E) The elastic seat portion is provided on the upper surface of the cylindrical body,
The mounting shaft body is cylindrical with the locking collars respectively locked to the lower surface of the tubular body, and the elastically seating elastic force causes the locking collars to elastically contact the lower surface of the tubular body. It must be rotatably inserted around the vertical axis.

(F) A recess is formed on one of the upper surface of the locking collar and the lower surface of the cylinder, and on the other hand, the mounting shaft is engaged with and disengaged from the recess by rotating the mounting shaft at a plurality of rotational positions. Each of them must have a convex part to hold it.

It is something.

According to a second aspect of the present invention, in the structure of the first aspect, the entire hook including the mounting shaft body is integrally molded of plastic, and a vertical elastic force is exerted on the outer periphery of the upper portion of the mounting shaft body of the hook. The elastic seat portion is configured by integrally providing a projecting piece that exerts.

According to a third aspect of the present invention, in the structure of the first aspect, a collar-shaped washer receiving portion is provided on an upper portion of the mounting shaft body in the hook, and a spring washer is provided below the washer receiving portion to provide elasticity. The seat is configured.

[0020]

According to the above construction, when the hook is attached, a click mechanism is formed between the lower surface of the cylindrical body and the upper surface of the locking flange by the concave portion and the convex portion, and the click mechanism causes the mounting shaft body to rotate a plurality of times. Held in position.

In this case, the elastic force of the elastic seat portion always causes the upper surface of the locking collar portion to be elastically pressed against the lower surface of the cylindrical body,
Since the click action by the convex portion and the concave portion is performed based on this spring action, abrasion and plastic deformation of the click portion hardly occur, and the click action is reliably performed for a long period of time.

Further, according to the second aspect of the present invention, since the entire hook is an integrally molded product of plastic, the number of parts is greater than that when a separate metal part (spring washer) is used for the elastic seat, for example. Low cost, easy assembly and low cost.

Since it is made of all plastic,
When shipping with your clothes hanging, the hook attachment part
There is no danger of reacting to a needle inspection machine for inspecting clothes for sewing needles.

On the other hand, according to the third aspect of the invention, since the spring washer which is a separate component is used for the elastic seat portion, the washer material is selected on the basis of the elastic force required for the elastic seat portion regardless of the material of the hook. You can choose freely. That is, it is possible to give an optimum elastic force to the elastic seat portion.
