Description

Device for sliding guides in stamped sheet metal for furniture drawers or similar.

Field of the Invention

This invention concerns a reinforcement device for sliding guides that consist of a fixed member that is anchored to the side of the furniture and provided with a front wheel on which a moving member runs that is anchored to the drawer and is provided with a rear wheel that runs along the fixed member.

Prior art

The sliding guides concerned here are subject to regulations according to which the fully open drawer must be capable of supporting vertical loads of 20, 25 and 30 kg. according to test standard, which in the most unfavorable case may be applied to the front (left or right) end of the fully open drawer. In this position the load bearing rests mostly on the front wheel of the fixed member and, through its axle, on the fixed member itself; which leads to this fixed member being provided with a sheet thickness greater than that strictly necessary for its function of facilitating the sliding of the drawer, a greater thickness that negatively affects the manufacturing cost of the sliding guide, in its weight, in the means of logistics that are necessary for its storage, for its handling and for its transport, in the cost and effectiveness of this transport and, as a result of all this, in something that increasingly occupies the attention of modern society, which It is the protection of the environment, through energy savings in the manufacture and distribution of manufactured products.

Explanation of the invention and Advantages

In the face of this state of affairs, and in relation to the aforementioned sliding guides stamped on sheet metal, the present invention proposes the incorporation of a steel supplement that, at least, has a reciprocal bore with the same front wheel axle. , and which, at least, has a flat face in correspondence with another flat face of said fixed member of the sliding guide.

According to an embodiment variant of the invention, the steel supplement is a washer with a bore that is coaxial with the axle of the front wheel. In accordance with this variant, a con fi guration is provided that a circular crown box is profiled on the fixed member, whose center coincides with the axis of the front wheel and whose contour and depth are respective continents of the perimeter and thickness of the washer; preferably the box is formed open towards the side of the fixed member, which is applied on the side panel of the furniture, and the washer and the box are circular.

According to another variant of the invention, the steel supplement is a plate that has a bore and an upper hole that are aligned, respectively, with the axle of the front wheel and with an upper hole of the fixed member which, vertically , is more or less aligned with said axis; in this case it is fulfilled that the hole of the plate has its reciprocal diameter of that of the front wheel axle and is coaxial with it; and the upper hole is elongated horizontally.

With any of these variants of execution of the invention, the fixed member of the sliding guide is provided with a reinforcement means in the most critical area, such as that where the front wheel thereof is; in the first variant, the axle assembly itself is used to hold the steel supplement so that it forms a compact package with the fixed member, the axle and the front wheel; in the second variant, for the fixing of the steel supplement, in addition to taking advantage of the shaft assembly itself, an upper hole is also used, which is provided with the fixed member for its mooring to the side of the furniture.

According to the invention, by reinforcing the weakest part in the normative tests so simply and economically, it is possible to reduce the thickness of the body of the fixed member of the guide to the minimum required for the effective fulfillment of its function of facilitating the sliding of the drawer; therefore, all the negative derivatives previously attributed to the greater thickness of this fixed member now translate into positive elements that, by contrast, offer savings in manufacturing costs, product weight, logistic storage, handling and distribution necessary, as well as their effectiveness, and, finally, of the energy savings that, in addition to a direct benefit to the parties involved in the manufacture and placing of the product on the market, revert in the care and conservation of the environment.
