Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rail for a drawer unit, and more particularly to a support structure for a drawer relative to the rail.

As shown in Fig. 1, the above conventional drawer unit consists of a fixed side rail (hour rail) a, which is attached to a cabinet (not shown), etc., and a movable side rail (inner rail) b.
The movable side rail b is provided with hooking protrusions c and d to support the drawer e.

In the drawer unit rail configured as described above, the support structure of the drawer e with respect to the conventional movable side rail b is as follows:
As shown in FIGS. 2 and 2, the locking protrusions C2d are provided from the rear and front ends of the movable rail b, protruding forward at the rear end and upward at the front end. In contrast, a hanging hole f is provided in the front-back direction of the rear wall e' of the drawer e, and a hanging hole g that opens downward is vertically provided in the side wall l, and the hanging holes f, g are provided vertically in the side wall l. Is the above latching protrusion C? d are configured to be engaged with each other.

However, if the support structure of the drawer is the conventional hole-fitting method described above, it is difficult to confirm the positions of the hooking holes f and g from the top of the drawer. There was a problem that it was extremely difficult to perform the work because the hole alignment with the machine was not left to the imagination.

In addition, generally speaking, the back wall e' and side wall l of the drawer e are often relatively thin, for example, about 13 mm thick, so in such a drawer, the supporting strength of the drawer may be affected to some extent. Considering that the latching protrusions c and d must have large diameters, the latching holes f and g are difficult to machine, and therefore the latching holes f2g and the latching protrusions c and d fit together. This poses problems such as it is difficult to create a large gap (room) between the two, and it is difficult to absorb variations in the left and right inner dimensions of the cabinet because the drawer does not shift in the left and right width direction.

Therefore, the present invention was developed in view of the above-mentioned conventional problems.
In a drawer unit rail in which a locking protrusion is provided on the movable side rail to engage and support the drawer, the plate thickness of the rear wall and side wall is thin by appropriately forming the locking protrusion from the movable side rail. Even in a drawer, the part that engages with the latch protrusion can be easily machined, the drawer can be easily engaged and supported, and the variation in internal dimensions on the left and right sides of the cabinet can be easily absorbed. That is its purpose.

The illustrations showing the embodiments of the present invention will be described in detail below.
As shown in FIGS. 3 to 5, there are hooks for supporting the drawer 3 from the inside of the rear end of the movable rail 2, which is slidably engaged with the fixed rail 1, and from the inside of the front end. Retaining protrusions 4 and 5 are provided horizontally inwardly protruding from each other, and the rear wall 3a of the drawer 3 has a retaining groove 6 that is open from the rear surface to the side surface and is cut horizontally, and a side wall. A locking groove 7 is formed on the front side of 3b, opening at the lower end and opening vertically toward the outside, and the locking protrusions 4 and 5 are respectively fitted into the groove 6°7. It is constructed to be able to support the drawer 3.

Here, the above-mentioned latching protrusions 4 and 5 may be provided in a plate shape by cutting and raising the movable side rail 2, as shown in the illustrated example.
Although not shown, a separate pin may be fixed to the movable rail 2 by welding or the like.

When provided in a plate shape as in the illustrated example, one of the latching protrusions 4 is provided horizontally with respect to the vertical direction, and the other latching protrusion 5 is provided so as to protrude perpendicularly with respect to the vertical direction. The vertical movement of the drawer 3 is restrained by the rear reed with the latching groove 6, while the longitudinal movement of the drawer 3 is restrained by the engagement between the latching protrusion 5 and the latching groove 7.

In addition, the latch protrusion 5 provided at the front end of the movable side rail 2 is provided relatively long so that when the drawer 3 is moved from side to side and adjusted, the latch protrusion 5 is relatively long so that the latch protrusion 5 is provided at the front end of the movable side rail 2. Either the engagement with the groove 7 is prevented from coming off, or the latching part 5a is bent at the inner end of the latching protrusion 5 as shown in the illustration, or the latching protrusion 5 is formed with a pin as described above. In this case, a flange-like hook may be provided at the inner end to be hooked to the inner surface of the side wall 3b of the drawer 3.

As explained above, according to the drawer unit rail according to the present invention, in the rail in which the movable side rail is provided with a latching protrusion to engage and support the drawer, the rear end portion of the movable side rail 2 and Since the locking protrusions 4 and 5 are provided laterally protruding inward from the front end, there are locking recesses extending from the rear wall 3a to the side wall 3b of the drawer 3 at positions corresponding to the locking protrusions 4 and 5. If the groove 6 is cut horizontally and a locking groove 7 is cut horizontally in the thickness direction at the lower end of the front side of the side wall 3b, each of the locking protrusions 4 and 5 can be The positions of the locking grooves 6 and 7 can be confirmed from the upper diagonal direction when installing the drawer 3, so that the locking projections 4 and 5 can be easily connected and supported. The drawer 3 can be attached to the movable rail 2 extremely easily and quickly.

Furthermore, since the locking protrusion 5 provided at the front end of the movable side rail 2 is horizontally installed facing inward, when it is engaged with the locking groove 7, the drawer can be displaced in the left-right direction.
As a result, variations in the left and right dimensions of the cabinet 8 can be absorbed, and even in the case of the drawer 3 where the side wall 3b is thin, the absorption of the variation is ensured, and the machining of the retaining groove 7 can also be done on the side wall 3.
This can be easily done without being restricted by the plate thickness of b.
