Description

[0001] The present invention relates to a drawer,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting device for a drawer body capable of adjusting its position, and more particularly, to a connecting device for a drawer body, And more particularly to a connecting device for a drawer body which can adjust the position of the drawer body by adjusting the positions of the rails and the drawer body for fixing the drawer body and extending the life of the drawer body.

In general, various furniture, a refrigerator, an oven, an electronic product, and the like are provided with a drawer body capable of storing the items according to their purposes. For example, in the case of furniture, the clothes stored in the furniture body are stored. In the case of the refrigerator, the refrigerator has a form in which various foods and vegetables are stored at low temperature by the cold air generated in the refrigerator body. The drawer body can be installed in the form of housing food to be stored and withdrawn while being moved inside and out of the main body. The drawer body is connected to the main body of each product by a sliding device so that the user can smoothly slide the drawer body by opening and closing the drawer body.

The sliding device for coupling the drawer body to the main body as described above is provided with a sliding body for rolling motion such as a ball or a roller so that the drawer body can be slid and taken out and drawn in. The drawer body can be smoothly operated, so that the convenience of the user can be improved. For example, the left and right wall surfaces of the drawer body installation space of the main body are provided with fixing rails, and both sides of the drawer body are guided by the fixing rails and provided with moving rails for reciprocating motion.

Therefore, in the conventional drawer body, the sliding body is provided between the fixed rail and the movable rail, so that the movable rail can perform smooth sliding motion on the fixed rail.

In addition, in the conventional drawer body, in addition to the two-stage sliding device of the fixed rail and the movable rail, a middle rail is provided between the fixed rail and the movable rail, and a three-stage sliding device is provided between the rails, It may induce a smooth reciprocating sliding motion of the drawer body.

Each of the rails of the above-described sliding device is configured so as to be prevented from being separated only by its own structure when coupled to each other so as to be guided. For example, the intermediate rail installed to be guided by the fixed rail can be prevented from being separated due to its own structure of the fixed rail and the intermediate rail or due to the structure of the sliding body. However, since the movable rails provided in the drawer body are required to completely separate the drawer body from the main body of the product by the user, a separate disconnector is installed. Such a separating device is capable of finally separating the drawer from the main body by operating the user in a state in which the drawer body is drawn out to the maximum draw-out position from the main body.

On the other hand, among recent products, for example, when a desk is used for a long period of time, the rail supporting the drawer body is bent because the weight of the drawer body is applied when the drawer is drawn out. That is, the conventional desk drawer has a problem that the rails fixing the drawer to be movable in the forward and backward directions are bent due to the influence of the weight of the drawer body.

Further, in order to completely draw the drawer body from the main body, the drawer body can be pulled out after the lever fixed to the rail is rotated so that the drawer body can be drawn out after the coupling state with the rail is released. There is a problem that it is very inconvenient for the user to operate the lever since the lever must be rotated to the opposite side of the rail.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a drawer body having an elastic force for easily separating a rail and a drawer body fixed to the body, The present invention relates to a connecting device for a drawer body which enables convenient position adjustment.

[

The present invention includes the above-described configuration. Hereinafter, the operation of the present invention will be described with the above-described configuration.

The supporting member 20 is fixed to the frame 1a of the drawer body 1 by a screw or a nail in the first fixing hole 211 of the fixing plate 21 and the extension plate 22 And is fixed to the back surface of the drawer body 1.

The lever member 10 is fixed to the lever 11 in such a manner that the rotation pin 24 is inserted into the fastening hole 112 formed at the end of the lever 11 so that the lever 11 is rotatable. At this time, the lever 11 is in a state in which the insertion protrusion 111 positioned at one end of the lever is seated in the fixing groove 411 formed at the side of the first rail 41, Prevent complete withdrawal.

The user pulls out the drawer body 1 by using the handle 31 attached to the front surface of the drawer body 1 and the third rail 43 fixed to the rear surface of the body is pulled out from the second rail And the second rail 42 slides on the upper surface of the first rail 41 after the third rail 43 is slid to the end of the second rail 42 The drawer body 1 is pulled out. At this time, the desk drawer body (1) is not completely drawn out in a state where the insertion protrusion (111) of the lever (11) is seated in the fixing groove (411) of the first rail (41).

Therefore, in order to completely draw the drawer body 1 from the main body, the user rotates the lever 11 in the outward direction, that is, the lever 11 in the direction in which the third rail 43 is positioned, The insertion protrusion 111 is completely disengaged from the fixing groove 411. Then, when the user releases the lever 11 from the hand, the lever 11 is returned to the original position by the elastic force of the spring 12.

Therefore, the drawer body (1) is released from the fixed state by the lever (11), so that when the user pulls the drawer body (1), the drawer body (1) can be completely drawn out from the body.

When the user then rejoins the drawer body 1 to the main body, the user may proceed in the reverse order of the above-described procedure.

As a result, the first rail 41 may be bent due to various causes such as frequent withdrawal of the drawer body 1 or use of the article for a long period of time or weight of the article stored in the drawer body 1. [ The position of the insertion protrusion of the lever 11 and the fixing groove 411 of the first rail 41 are not aligned with each other due to the warping of the first rail 41, It is not possible to recombine.

Therefore, when a failure occurs due to the warping of the rails 41, 42 and 43, the user operates the position correcting member 30 to reattach the drawer body 1 after pulling out the drawer body 1, The position of the fixing groove 411 of the lever 41 is corrected to coincide with the insertion protrusion 111 of the lever 11.

That is, when the user holds the handle 31 of the position compensating member 30 and pushes the handle 31 in the direction of the first rail 41, the moving projection 34 of the handle 31 moves the moving supporting plate 28 The lower end of the inclined block 32 is inserted into the lower portion of the first rail 41 while being moved along the groove 281. Therefore, the height of the first rail 41 is increased along the inclined surface while the inclined block 32 is inserted. Therefore, when the user holds the handle 31 and pushes it forward, the height of the first rail 41 is raised, and when the user pushes the handle 31 backward, the height of the first rail 41 is lowered.

In this way, the user uses the knob 31 to move the inclined block 32 forward and backward to align the position of the insertion protrusion 111 with the fixing groove 411. At this time, the second fastening protrusion 331 on the upper surface of the fastening block 33 is engaged with a plurality of first fastening protrusions 261 formed on the back surface of the stopper 26 to fix the position of the inclined block 32 .

Therefore, the drawer body (1) can correct a failure due to warping or the like of the rail member (40) by the position correcting member (30), and can be used for a long time. In addition, since the rotating direction of the lever 11 is rotated to the outside of the drawer body 1, the drawer body 1 to which the present invention is applied can be convenient for the user as a form suitable for the human body.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
