Abstract

(57) [Abstract] [Purpose] To prevent deformation and damage of the horizontal piece of the inward L-shaped drawer rail made of plastic and the engaging piece for mounting to the housing. A vertical piece 5 having an engaging piece 8 for mounting on the housing 1 on an outer side surface and a horizontal piece 9 are provided, and the lower edge of the vertical piece 5 extends downward from the horizontal piece 9 to form a housing. A vertical pressure receiving piece 10 that can contact the inner surface of the body 1 is continuously provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rail for supporting a relatively low and lightweight drawer or tray in a cabinet.

[0002]

[Prior art]

 Many of the conventional rails of the above-mentioned type have an L-shaped cross section as described in, for example, Japanese Utility Model Publication No. 58-16698, and are provided on the outer surface of the vertical piece to be attached to the mounting hole in the cabinet housing. It is common to provide an engaging piece for engaging. However, the rail is usually manufactured by molding plastic in terms of cost and workability.

[0003]

[Problems to be solved by the device]

 A rail made of plastic and having an L-shaped cross section is inherently insufficient in strength, and in particular, its horizontal pieces and engaging pieces may be deformed by the load of the drawer or tray that is repeatedly reciprocated. There is a risk of shearing.

[0004]

[Means for Solving the Problems]

 According to the present invention, a drawer in a cabinet made of plastic and having an L-shaped inward cross-section and provided with engaging pieces for engaging and locking with holding holes in the housing at the front and rear portions of the outer surface of the vertical piece. In the rail for use, a vertical pressure receiving piece extending below the horizontal piece is continuously provided at the lower edge of the vertical piece so as to contact the inner side surface of the housing.

[0005]

[Action]

 The load on the horizontal piece is supported by the housing via the pressure receiving piece, and the pressure receiving piece prevents the vertical piece from tilting inward.

[0006]

【Example】

 1 is a perspective view of a tray cabinet including the rail of the present invention, FIG. 2 is a vertical sectional view taken along line II-II in FIG. 1, FIG. 3 is an enlarged vertical sectional view taken along line III-III in FIG. 2, and FIG. 2 is an enlarged vertical sectional view taken along line IV-IV in FIG. 2, and FIG. 5 is a perspective view of a pair of left and right rails.

A large number of rails (4) and (4) are attached to the side surfaces (2) and (2) of the casing (1) and the intermediate wall (3) at equal heights on the opposing surfaces.

The rail (4) is made of plastic and basically has an inward L-shaped cross section. Hook-shaped engagement that can be fitted from above to the holding holes (7) in the inner surfaces of the front and rear struts (6) and (6) provided on the opposing surfaces of the side wall (2) and the intermediate wall (3) of the body (1) Pieces (8) (8) are provided in a protruding manner.

At the lower edge of the vertical piece (5) of the rail (4) to the lower side of the horizontal piece (9) in the range extending slightly rearward of the front engaging piece (8) from the front end of the rail (4). The extending vertical pressure receiving piece (10) is connected in series.

The front end of the horizontal piece (9) is an inclined edge (11) facing inward and rearward. The rear ends of the horizontal piece (9) and the vertical piece (5) are connected by a connecting piece (12).

[0011] On the inner side of the lower surface of the horizontal piece (9) near the front part, the lower tray (13) that is pulled out is locked to the upper edge of the rear surface plate to prevent the tray (13) from coming off. A protrusion (14) is formed.

The rail (4) is not attached to the housing (1) by fitting the engaging piece (8) into the holding hole (7) of the column (6) from the inside. , There is no difference from the conventional one.

Further, at this time, it is also the same as in the prior art to provide the inward cut and raised piece (15) on the inner surface of the column (6) to prevent the rail (4) from moving upward.

[0014]

[Effect of device]

 (a) Since the load on the horizontal piece of the rail is transmitted as a pressing force to the housing via the pressure receiving piece, an excessive bending moment does not act on the root portion of the horizontal piece.

(B) Since the inward inclination of the upper portion of the vertical piece is restrained by the presence of the pressure receiving piece, an excessive load is applied to the root of the engaging piece, and the engaging piece is deformed or torn off. Is prevented.

(C) Since the front end of the horizontal piece is an inclined edge that faces inward and rearward, the shear stress at the front end of the horizontal piece due to the tray is dispersed, and the risk of the horizontal front end being damaged is small.

(C) Since the rear ends of the horizontal piece and the vertical piece are connected to each other by the connecting piece, the relationship angle between them is excessively large, and the damage is prevented.
