Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a hanger whose left and right arms are divided and folded as necessary.

[Conventional technology]

As this kind of hanger, the applicant of the present application previously filed Utility Application No. 177881 (November 17, 1988)
No. 60-83478). As shown in FIGS. 4 and 5, this hanger consists of a rack rod 45, which has a vertical hole 44 for inserting the support shaft in its core, inside a central case 43 to which a support shaft 42 of a hanging hook 41 is fixed. A fan-shaped gear 47 that meshes with rack teeth is provided on the opposing end surfaces of the divided left and right arms 46, and the arms are swingably attached to the case via pins 48.

The rack rod 45 protrudes from the lower surface of the case 43, and a plate spring-like stopper 49 is attached to this protrusion so as to be able to rise and fall freely, and a compression coil spring 50 is attached between the upper end of the rack rod and the top surface of the case. A downward force is applied to the rack rod.

The leaf spring-like stopper prevents the arm from folding under the weight of the clothes, that is, prevents the rack bar from rising, and is designed to be pushed in with the fingertip.
The coil spring 50 has the force to automatically open the folded arm due to its restoring elasticity when no clothes are hung on it.

[The problem that the idea aims to solve]

However, in this known hanger, when folding the arm to put on and take off clothes, the stopper 49 must be pressed down to the end surface of the rack rod (see arrow direction A in FIG. 4), and the protrusion at the lower end of the rack rod 45 must be Two operations must be performed at the same time: pushing it up into the case 43 (see arrow direction B in Figure 5).
The drawback was that it was impossible to hold clothes with one hand while operating the clothes with the other hand.

This invention was made in view of the problems of the conventional examples, and its purpose is to provide a folding type hanger whose arm can be opened and closed in one motion with one-handed operation. It is something.

[Means for Solving the Problems] In order to achieve the above object, the hanger of this invention has an outer cylindrical body that enters into the case when a stopper is pushed into the lower end of the rack rod, so that it can freely slide up and down. It is installed.

[Effect]

In the hanger constructed in this manner, when the outer cylinder is pushed up, the stopper is pushed into the rack rod in one movement, and at the same time, the rack rod is retracted into the case and both arms are folded.

〔Example〕

Figures 1 to 3 show examples of this invention,
In this hanger, a prismatic rack rod 5, which has a vertical hole 4 for inserting a support shaft with a circular cross section in its core, is attached to a central case 3 to which a support shaft 2 of a hanging hook 1 is fixed, so as to be able to slide vertically. The left and right arms are separated 6
A sector gear 7 that meshes with the rack teeth is provided on the opposite end surface of the arm, and the arm is attached to the case via a pin 8 in the center of the gear so as to be able to swing vertically (see arrow direction X in Figure 1). .

The rack rod 5 protrudes from the square hole 9 on the lower surface of the case by a required dimension, and a pair of leaf spring-like stoppers 10 are attached to this protrusion so that they can rise and fall freely, and an outer cylinder 11 that presses the stoppers can slide vertically. installed on. A compressed coil spring 12 for pushing down the outer cylinder is loaded between the outer cylinder and the rack rod.

A support shaft 2 is provided between the upper end of the rack rod 5 and the case 3.
A compressed coil spring 13 is loaded, which has a larger elastic force than the coil spring 12 centered on the arm, and is used to automatically raise the arm after the arm is folded.

FIG. 3 is a perspective view of the rack rod 5, stopper 10, and outer cylinder 11, which will be explained in detail. A substantially V-shaped leaf spring-like stopper 10 is fitted into a vertical recess 14 provided on one opposing surface of the prismatic rack rod 5, and a rivet 15 is provided at the lower end. The tip extends into the upper end of the recess 14 and lies down (see Fig. 2).

A vertical guide groove 16 for the outer cylinder is provided on the other opposing surface of the rack rod 5 to facilitate vertical sliding of the outer cylinder. Further, at the lower end of the rack rod 5, there are flanges 1 on both sides of the guide groove 16 to prevent the outer cylinder from coming off.
7 is provided to protrude outward.

The outer cylindrical body 11 has approximately the same external dimensions as the rack rod 5, has a retaining collar 18 protruding inwardly at its upper end opening, and has a longitudinal protrusion on the same opposing surface that fits into the guide groove 16 of the rack rod. Article 19 is provided. Rack stick 5
Using the elasticity of the material, the outer cylinder 11 is fitted over the collar 17.

Furthermore, when the outer cylindrical body 11 is pushed up by placing a finger on the bottom surface, the lower coil spring 12, which is weaker than the upper coil spring 13, is compressed, as shown in FIG.
Only the outer cylindrical body rises along the rack rod and sinks into the case while pushing the stopper, and at the same time the rack rod rises and both arms are folded.

Note that the guide groove 16 of the rack rod and the vertical protrusion 19 of the cylinder can be omitted.

When using the hanger, normally, as shown in FIG. 1, the lower end of the rack rod protrudes from the case due to the expanded elasticity of the compressed coil spring 13, and the stopper 10 engages with the lower surface of the case. The arms are opened almost horizontally. Even if a load is applied by hanging clothes on the arm, the arm is held in a horizontal position by being locked by the stopper.

Next, when you remove your clothes or fold your arm to hang new clothes, place your index finger C and middle finger D on the top surface of the case, and place your index finger C and middle finger D on the bottom surface of the case, as shown in Figure 2. When the outer cylinder is pushed up while placing the thumb E on 11, both arms are folded in one action as described above, and when the thumb is removed from the outer cylinder, both arms are automatically opened.

[Effect of idea]

This idea is structured as described above, so
This produces the following effects.

By simply pushing up the outer cylindrical body attached to the lower end of the rack rod, the stopper retracts and the rack rod is pushed up, allowing both arms engaged with this to be folded in one motion, allowing the arm to be fully extended with one hand. It can be opened and closed, making it very easy to put on and take off clothes.
