Description

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

Field of the Invention

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

Prior art

The sliding guides concerned here are subject to regulations according to which the fully open drawer has of being able to support 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) front of the drawer fully open In this position the load bearing it falls mostly on the front wheel of the fixed member and, through its axis, on the fixed member itself; which it's leads to this fixed member being provided with a greater sheet thickness that the strictly necessary for its function of facilitating the drawer sliding, greater thickness that has a negative impact on the manufacturing cost of the sliding guide, in its weight, in the logistics means that are necessary for storage, to its handling and for its transport, in the cost and effectiveness of this transport and, as a result of all this, in something that every time occupies more attention of modern society, what is the protection of the environment, through energy savings in manufacturing and distribution of manufactured products.

Explanation of the invention and Advantages

Faced with this state of affairs, and in relation to the mentioned sliding guides stamped in sheet metal this The invention proposes the incorporation of a steel supplement that, when less, it has a reciprocal diameter drill that the own front wheel axle, and that at least has a face flat in correspondence with another flat face of said fixed member of the sliding guide.

According to an execution variant of the invention the steel supplement is a washer with a drill that It is coaxial with the front wheel axle. According to this variant a configuration consisting of that in the fixed member a circular crown box is profiled, whose center coincides with the axle 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 fixed member side, which is applied on the side panel of the furniture, and the washer and box are circular.

According to another variant of execution of the invention the steel supplement is a plate that has a drill and an upper hole that are aligned, respectively, with the shaft 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 true that the hole in the plate has its diameter reciprocal of the one with the front wheel axle and is coaxial with this; and the upper hole is elongated horizontally.

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

According to the invention, by reinforcing so simple and economical way the part that is weakest in the normative tests, it is possible to reduce the body thickness of the fixed member of the guide to the minimum required for compliance effective of its function of facilitating the sliding of the drawer; for the therefore, all the negative derivatives previously attributed to the greater thickness This fixed member now translates into positive elements that, by contrast, they offer manufacturing cost savings, weight of product, of the logistic means of storage, handling and necessary distribution, as well as their effectiveness, and, finally, of the energy savings that, in addition to a benefit direct for the parties involved in manufacturing and commissioning of the product in the market, revert in the care and conservation enviroment.

Exhibition of a preferred embodiment

Regarding the drawings and references above listed, an execution mode is illustrated in the attached drawings preferred object of the invention, which refers to a device for sliding guides in stamped sheet metal for furniture drawers or similar, where, as illustrated in a manner schematically figure 1, the sliding guide consists of a fixed member (1) that is anchored to the side of the furniture (3) and provided with a front wheel (5) on which a moving member (2) runs which is anchored to the drawer (4) and is provided with a rear wheel (6) that runs along the fixed member (1).

In this context, the essence of the invention it consists of a steel supplement (7) that, at least, has a reciprocal diameter borehole (8) of which the shaft (9) itself has the front wheel (5), and that at least has a flat face in correspondence with another flat face of said fixed member (1) of the sliding guide

Figures 2 to 5 illustrate a variant of execution in which the steel supplement (7) is a washer (7a) with a drill (8) that is coaxial with the axle (9) of the wheel front (5). In this variant a particularity of the invention consisting in that the fixed member (1) is embedded (figure 5) a circular crown box (10), whose center coincides with the axle (9) of the front wheel (5) and whose contour and depth are respective continents of the perimeter and thickness of the washer (7a); preferably it is contemplated that both the box in circular crown (10) as the washer (7a) are circular, although they could be of any other geometric figure; I also know has chosen as preferred an execution in which the crown box circular (10) is formed open towards the side of the fixed member (1), which is applied on the side panel of the furniture (3); though it could also be formed open towards the side of the wheel front (5).

Another embodiment variant of the invention is the which illustrate figures 6 to 9. It consists in that the supplement of steel (7) is a plate (7b) that has a hole (8) and a hole upper (11) that are aligned, respectively, with the shaft (9) of the front wheel (5) and with an upper hole (12) of the fixed member (1) that, vertically, is more or less aligned with said axis (9); in this solution the hole (8) of the plate (7b) has its reciprocal diameter of the one with the wheel axle (9) front (5) and is coaxial with it; instead, to facilitate the assembly, the upper hole (11) is elongated horizontally (figures 6 and 8). In this case the fixed member does not present the crown box circular (10) of the previous variant and the plate (7b) is applied on the front face of the fixed member (1) of the sliding guide.
