The present invention relates to a guide rail for a drawer, and more particularly, the mounting direction of the left and right sides of the drawer by changing its structure so that the guide direction of the guide rail for guiding the drawer is not defined in one direction and can be transported in the front-rear direction. The present invention relates to a guide rail for a drawer capable of mounting a guide member having the same structure on a side of a drawer regardless of the mounting direction without manufacturing each of the guide members to be manufactured differently.

In general, a drawer is installed in a cabinet or a desk, and the like, and is used as a space for storing personal items, files, various objects, and the like according to the purpose. Such a drawer can be slidably moved by a guide rail comprising a first guide member mounted on both sides A of the drawer housing and a second guide member mounted on both sides of the drawer B. FIG.

1 and 2 showing the guide rail 10 for the drawer according to the prior art, the first guide member 20 is the side and the bolt of the drawer housing (A; At least one coupling hole 22 is formed to be coupled using a screw, etc., while the first and second stoppers 26 and 28 for limiting the transfer distance are formed on both end sides of the recess 24, and the upper and lower sides are protruded. The first conveyance groove 30 having a predetermined depth is formed on the outer surface of the bent portion, the second guide member 40 has a size that can accommodate the first guide member 20 on the inner surface A third stopper 44 protrudes from one end of the groove portion 42, and a second transfer groove 46 having a predetermined depth is formed on an inner surface of the upper and lower bent portions facing the first transfer groove 30. To support and engage the drawer, a protrusion 48 having a screwing hole is formed on the rear surface thereof.

In addition, when the first guide member 20 is accommodated in the second guide member 40, the upper and lower bent portions may be spaced apart by a predetermined interval, and the roller bracket having a predetermined shape may be mounted with one or more rollers 52 slidingly moved. 50 is provided.

As such, when the guide rail 10 including the first 20 and the second guide member 40 is attached to the side of the drawer B and the drawer accommodating part A, the guide rail 10 is opened and closed. Sliding movement of the drawer is made smoothly according to the movement of the roller bracket 50 seated in the first (30) and the second transfer groove (46).

That is, when the drawer is pulled in the state in which the drawer is stored in the drawer accommodating part (Fig. 3a) as shown in Figs. 3a and 3b (in the direction of the arrow in Fig. 3b), the first transfer groove of the first guide member 20 The roller bracket 50 and the second guide member 40 are slidably moved in the moving direction of the drawer along the 30, and at this time, when the drawer is pulled to the maximum, the second stopper 28 is formed on both end surfaces of the roller bracket 50; And the third stopper 44 is caught, thereby preventing the second guide member 40 and the roller bracket 50 from being separated from the first guide member 20.
