Abstract

PROBLEM TO BE SOLVED: To easily apply force and to enable smooth operation in the case of manually elevating a storing device by disposing a slide rail at an angle to the storing device, and elevating an elevating rack installed in a comparatively elevated spot such as a wall surface or the like along the inclination. SOLUTION: A flat type spiral spring 3 has one end fixed to a fitting 2 fitted to an outer casing 1, and the other end fixed to a shaft 4 fixed on the top plate of a moving rack 6 through a fitting 5. The moving rack 6 has both side parts movably supported on slide rails 7a, 7b of an expansion structure fitted at an angle θ of inclination to the side of the outer casing 1. The used flat type spiral spring 3 is set to spring force such that the weight of the moving rack 6 which stores goods and the restoring force are balanced. Balance weights 8a or/and 8b are removably installed in suitable places of the moving rack 6 according to the weight of the stored goods. Thus, the moving rack 6 can be always lightly elevated regardless of the weight of the moving rack 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a storage device which is installed at a relatively high place such as a wall surface, so that the storage device can be moved up and down to facilitate storage at a high place. Further, by pulling it forward, storage is facilitated. Further, the operation force in this movement is reduced.

[0002]

2. Description of the Related Art Conventionally, a method has been adopted in which a load applied to a storage device in a storage device is balanced by a coil spring or a weight to reduce an operation force for movement. In this method, it is difficult to balance by taking in and out of the stored items, and when setting the balance weight, it is necessary to consider a state close to the sky. When the load is increased, the operating force is increased and the usability is deteriorated, and the device must be used with a relatively small load.

[0003]

It is an object of the present invention to operate smoothly with a small operating force when the load is relatively high.

[0004]

SUMMARY OF THE INVENTION Instead of vertically moving the storage device up and down, the storage device is pulled forward along the inclination and pushed toward the opposite side, thereby reducing the operating force and facilitating the input of the force.

[0005]

The slide rail is formed to have an angle of θ with respect to the storage device, and the weight W of the storage device in the storage device is represented by Sin θ ·
W = P. The operation force of P is made several steps lighter than the weight of W.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The other end of a flat spiral spring 3 having one end fixed to a bracket 2 attached to an outer casing 1 is fixed to a shaft 4,
The shaft 4 is fixed to a moving shelf 6 via a fitting 5. The movable shelf 6 is attached to the side surface of the outer casing 1 with an inclination angle θ, and is carried by slide rails 7a and 7b.
Further, the slide rails 7a and 7b form a storage device so as to slide smoothly by a ball. The flat spiral spring 3 is set so that the weight of the moving shelves 6 containing the stored items and the force to return to the original position are balanced via the slide rails 7a and 7b. Also, the balance weights 8a and 8b have no balance weight due to the lightness and weight of the stored items, and the balance weights 8b and 8a +
8b. Further, the same effect can be obtained by preparing and switching between strong, medium and weak for the spring / flat spiral spring 3 instead of the balance weight.

[0007]

As the slope is formed by the slide rail, it is possible to move up and down lighter than to move up and down vertically.
Furthermore, when manually moving the storage device formed on the wall surface on the opposite side of the work table, it is easier to apply force when pulling toward the front than when moving up and down with the hand extended, and it is possible to operate smoothly. It is easy to put things in and out because things come to you. In addition, by adjusting the balance weights 8a and 8b, it is possible to always operate with a constant force.
