Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a suspension structure for drawers in steel cabinets, desks, etc., and particularly to a connection structure between the drawer and a guide rail.

B. Prior art As a conventional means for fixing a guide rail to a drawer, a drawer rail with a ∠-shaped cross section is welded in advance to the drawer side by spot welding or the like, and the guide rail is attached to this by means such as a locking claw. It was designed to be locked and fixed.

C. Problems that the invention aims to solve The process of forming the drawer side plate and the drawer rail separately and then welding them as described above is not necessarily suitable in terms of both processing costs and material costs, and it is not necessary to further simplify the process. It was desirable to do so.

D. Means for solving the problem Therefore, in the present invention, the conventional drawer rail fixed to the drawer side by spot welding etc. is molded integrally with the side plate, and the guide rail is suspended and fixed to this. This is aimed at reducing manufacturing costs, namely, by bending the drawer side plate outward to form a drawer rail with a ∠-shaped cross section consisting of a slope and a water surface, and drilling a locking hole near the front end of the horizontal surface. A locking groove is bored at the rear end, and a locking protrusion that fits into the locking hole and a bent protrusion that fits into the locking groove are cut and raised on the guide rail. This invention proposes a suspension structure characterized by the following, and the gist of the invention will be explained below based on the embodiments shown in the drawings.

E. Embodiment Fig. 1 is a partially exploded perspective view showing one embodiment of the suspension structure of the present invention, Fig. 2 is a partially cutaway vertical front view of the same structure, Fig. 3 is an exploded perspective view of the suspension part, FIG. 4 is a perspective view of a cabinet equipped with the same structure.

In the drawings, reference numeral 1 denotes a drawer, which consists of a pair of side plates 2, a front plate 3, a rear plate 4, and a bottom plate (not shown), and the side plate 2 is integrally molded with a drawer rail 5 protruding outward during press working. The drawer rail 5 has a ∠-shaped cross section consisting of a slope 5a and a water surface 5b, and a locking hole 6 is bored near the front end of the horizontal surface 5b, and a locking groove 7 is formed at the rear end. It has a notch. Reference numeral 8 denotes a guide rail, which is formed into a U-shaped cross section, and both an upper edge 8a and a lower edge 8b are bent downward. A locking protrusion 9 that engages with the locking hole 6 of the drawer rail 5 and a bent protrusion 10 that engages with the locking groove 7 are cut and raised on the upper surface 8c. 9 has a raised portion 9a formed therein.

In addition, 11 is a cabinet, 12 is a fixed rail latched to the inner plate 13 of the cabinet 11, and 14 is a fixed rail.
is a movable rail that has a substantially S-shaped cross section, and between these guide rails 8, movable rails 14, and fixed rails 12 are idler rollers 15, stoppers and slider 16,
Intermediate point stopper 17, slider 18, stopper 19, roller 20 and frame 21 that holds it, stopper 22, ball 23, and front and rear rollers 24,
25 etc. are interposed, and by rotating and sliding on the rail,
The drawer 1 can be moved in and out smoothly as in the conventional drawer, and 26 is a pull.

F. Function As described above, in the suspension structure of the present invention, the drawer rail 5 is integrally molded on the side plate 2 of the drawer 1, and the locking protrusion 9 of the guide rail 8 is passed through the locking hole 6 of the horizontal surface 5b. The raised portion 9a is engaged with the rail 8 side, and in this state, the bent protrusion 10 is bent inside the drawer rail 8 and is engaged and fixed in the engagement groove 7.

Effects of the invention Therefore, there is no need for spot welding to the drawer side plate 2 as in the past, and since the side plate 2 is bent to form the drawer rail 5 itself, production costs can be reduced by approximately 20%. With the excellent advantages obtained, the practical benefits are great.
