Description

DESCRIPTION

Multi-purpose drawer guide

FIELD OF THE INVENTION

The present invention relates to a multi-purpose drawer guide of the compounds comprising at least one fixed inner section and a mobile outer section, with the possibility of incorporating an intermediate section in the case of telescopic guides, which has rolling elements between the fixed interior sections, mobile exterior and intermediate section.

STATE OF THE PREVIOUS TECHNIQUE

At present and as a reference to the state of the art, it is usual and known to use drawer guides composed of a fixed section attached to the furniture and a mobile outer section in the case of guides with partial exit of the drawer. It is also known the use of telescopic drawer guides composed of a fixed section attached to the furniture, a mobile intermediate section and a mobile outer section. In both cases the rolling between the fixed and the mobile part is produced by using ball bearing cages housed on the outer walls of the fixed section, however this type of rolling presents reliability problems when used in drawers with a weight high.

For example, patent ES 2029451 describes a sliding ball guide system comprising an inner rail, an outer rail and three sets of balls interposed between the rails and placed in a triangular arrangement, the outer rail being configured to provide three tracks for the three sets of balls and having the inner Y-shaped rail in cross section with a rod extending outward from the center of the arrangement between two sets of balls and through a slit in the outer rail and two arms extending outwardly from the center of the arrangement between the other pairs of ball games.

The ES 2200018 patent shows a telescopic drawer guide, with a guide rail that can be attached to the furniture body, a telescopic rail attached to the drawer, an inner profile rail that joins the guide rail and the telescopic rail, to which it is associated at least one elongated cage in which a bearing body is housed, and metal end stops that limit the end positions of the telescopic rails and that can strike against fixed stops. In the final zones each cage is equipped with elastic auxiliary stops associated with the end stops, which are separated from the end stops of the removable telescopic rail.

Patent ES 2096465 describes an extraction guide for a drawer drawer with a guide rail and with an extraction rail, as well as an internal profiled rail provided with several ball guides and which joins the guide rail to the extraction rail, being the balls are arranged by games and between the two outer surfaces of the inner profiled rail and the inner surfaces of the guide rail and the extraction rail, so that they can roll. Guide rail and extraction rail formed with an angled cross-section, running the two free marginal zones, located so that they move away from each other to form ball guides, in each case in an inward-facing arc, in such a way that in each case three balls form a set of balls.

The patent ES 2245056 describes a drawer extraction guide with a guide rail that is fixed to the furniture body and a rolling rail adaptable to the drawer and guided by bearings, and with a profiled rail provided with raceways for said bearings located at one or both ends, where the area of the profiled rail adjacent to the raceways is misaligned with respect to the vertical so that said area is located in the direction or next to the direction of the resulting side forces incident on the drawer removal guide.

EXPLANATION OF THE INVENTION AND ADVANTAGES

Faced with this state of affairs, the present invention deals with a multipurpose drawer guide that, in relation to the existing, differs in a simpler constitution to install that allows to save on repairs and replacements by being valid for both simple and telescopic slides .

For this purpose, the multipurpose drawer guide of the compounds composed of at least one fixed inner section and a mobile outer section, with the possibility of incorporating an intermediate section in the case of telescopic guides; multipurpose guide in which the mobile outer section houses a combination of upper central roller and lower side balls for rolling over a movable head of upper wall and lower lateral cavities, the configuration and dimension of the mobile outer section being able to accommodate both the guide Single drawer or telescopic guide.

Thanks to this, it is possible that the fixed outer section can be mounted interchangeably with simple or telescopic sliding guides, reducing manufacturing and replacement costs, since it is only necessary to manufacture a single type of mobile outer section and moving head.

Additionally, the rolling between the two parts (mobile outer section and moving head) is produced by means of an upper central roller bearing and lower lateral balls that allow the sliding guide to be installed in heavy-weight drawers, with the distribution of more distributed efforts on the upper wall. , which produces less wear avoiding the appearance of footprints and gaps between the pieces that make up the multi-purpose drawer guide. The upper wall can have different geometric configurations according to the needs of the drawer in which it is installed, being configured as a flat surface, or as a slightly curved surface at its ends.

Another advantage presented by the invention is that in the telescopic guide execution mode the moving head of the intermediate section houses in its four round inner corners inner balls for rolling on a head with four cross faces of the fixed inner section.

Thanks to this configuration, the moving head becomes the intermediate section of the telescopic slide without the need to manufacture another additional part.

Finally, another feature of the invention is that in another embodiment the movable head is attached to the fixed inner section.

Thanks to this configuration, it is possible to fix the position of the moving head in its execution as a multipurpose guide with a simple drawer.
