Abstract

The present invention relates to an apparatus for preventing release of a roller of a drawer, comprising: a fixed plate attached to both sides of furniture as a target fixture and having an idly rotating guide roller provided at one end portion thereof; and a moving plate attached to both sides of a drawer and having a moving roller provided at the other end thereof and rotated by the medium of the fixed plate, wherein a first spring is provided between the guiding roller and the fixed plate to tightly attach and support the guide roller by elastic repulsive force toward the moving plate, and a second spring is provided between the moving roller and the moving plate to tightly attach and support the moving roller toward the fixed plate by elastic repulsive force.

Description

[0001] The present invention relates to a drawer roller,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for preventing a drawer roller from being separated from a drawer, Thereby preventing the moving roller from being separated from the fixing plate.

As is generally known, the term "kagura" refers to a desk or a sofa used in a home or an office, and in particular, a desk, a cabinet, a closet, and a drawer For example.

On the other hand, most of the various furniture produced with various purposes and functions according to the purpose have separate drawers to provide an enclosed space for storing the articles suitable for the use of the furniture or the articles used in the surroundings.

Various types of drawers have been proposed for smoothly coming and going out of furniture. The most common method is to install a guide having a fixing plate and idling roller on both sides of the furniture, and a moving plate and a fixing plate on both sides of the drawer And a moving roller that slides as an intermediate is mounted.

Therefore, the moving plate mounted on the drawer is engaged with the fixing plate mounted on both sides of the furniture, and the moving roller comes into rolling contact via the fixing plate, and the drawer comes and goes out.

However, the roller structure of such a general drawer has the following problems.

That is, when the moving roller is supported on the sliding surface of the fixed plate, when the draw-out operation of the drawer is repeated, the moving roller is separated from the sliding surface of the fixed plate, and the drawer often falls off the furniture.

In addition, the fixing plate attached to both sides of the furniture is distorted due to the environmental factors such as the variation of the temperature, the difference of the temperature and the humidity, the physical impact due to the impact, the weight and the load applied to the furniture, A clearance is generated between the fixed plate and the movable plate which must be maintained at a constant interval, and the movable roller that slides through the fixed plate is detached from the fixed plate and the drawer is frequently dropped.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a fixing device for fixing a moving roller sliding on a fixing plate provided on both sides of a furniture to be fixed to the fixing plate at all times by an elastic repulsive force Thereby preventing the moving roller from being detached from the stationary plate.

It is another object of the present invention to provide a sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding type sliding member Thereby preventing the drawer roller from being detached from the fixing plate.

In order to achieve the above object, according to the present invention, there is provided a refrigerator comprising: a stationary plate attached to both sides of furniture to be stationary and having guide rollers idling at one end; And a moving plate attached to both sides of the drawer and having a moving roller rotated at the other end via a fixing plate; Further comprising: a first spring disposed between the guide roller and the fixed plate to closely support the guide roller toward the moving plate by an elastic repulsive force; And a second spring disposed between the moving roller and the moving plate for urging the moving roller against the fixed plate by an elastic repulsive force.

The present invention having the above-described configuration can achieve the following effects.

First, there is an effect of preventing the moving roller from being dislocated from the stationary plate by making the moving roller sliding through the stationary plate provided on both sides of the furniture come into close contact with the stationary plate at all times by the elastic repulsive force.

Second, the guide rollers that idle on the fixed plates mounted on both sides of the furniture and guide the smooth movement of the movable plate are brought into close contact with the movable plates mounted on the drawers by the elastic repulsive force, so that the movable rollers There is an effect of preventing detachment from the fixing plate.

2 (a) is a sectional view taken along the line AA in Fig. 1
2 (b) is a sectional view taken along line BB of Fig. 1

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view showing an apparatus for preventing separation of a drawer roller according to the present invention, and FIGS. 2A and 2B are sectional views taken on line A-A, B-B in FIG.

As shown in the drawings, the drawer roller separation preventing device according to the present invention includes a fixing plate 10 attached to both sides of furniture to be fixed and having a guide roller 11 idling at one end thereof, And a moving plate 20 attached to a side surface of the fixed plate 10 and provided with a moving roller 21 for rotating the fixed plate 10 at the other end thereof. Do.

The fixing plate 10 and the moving plate 20 are coupled with each other in an interlocking manner and the guide roller 11 provided on the fixing plate 10 contacts the lower surface of the bent portion bent on the upper side of the moving plate 20 And the moving roller 21 provided on the moving plate 20 is in contact with the upper surface of the bent portion bent downwardly of the fixed plate 10.

The dominant feature of the present invention is that the guide roller 11 is moved between the guide roller 11 mounted on the fixed plate 10 and the fixed plate 10 on which the guide roller 11 is mounted, A first spring 12 which is supported in close contact with the plate 20 by an elastic repulsive force is provided and a moving roller 21 mounted on the moving plate 20 and a moving plate (See FIGS. 2 (a) and 2 (b)), the moving roller 21 is urged toward the fixed plate 10 by an elastic repulsive force.

The first spring 12 resiliently mounted on the guide roller 11 is urged by the second spring 22 elastically supported by the guide roller 11 in such a manner that the guide roller 11 is urged toward the moving plate 20, The moving roller 21 is prevented from being detached from the fixed plate 10 even if the drawer is repeatedly protruded or retracted because the moving roller 21 is urged toward the fixed plate 10 and is elastically supported .

The first and second springs 12 and 22 elastically provided on the guide roller 11 and the moving roller 21 are used to buffer the spring when the drawer is projected and unloaded. The rotation of the moving roller 21 is smooth.

Thus, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

It is therefore to be understood that the embodiments described above are to be considered in all respects as illustrative and not restrictive and the scope of the invention is indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
