DETAILED DESCRIPTION OF THE INVENTION

[0037] The object of the invention is a bearing system for a slide that achieves by means of a common support profile and a series of elements that combine or change to have a bearing system for a slide both for mounting with bearing in the frame and for mounting with bearing in the pane, maintaining both functionally and visually a similar recess in the frame in both configurations.

[0038] The bearing system for a slide, which is the object matter of the invention, comprises a U-shaped profile (1) with two wings (2) and a web (3), configured to house within it the other components of the bearing system for a slide, object matter of the invention.

[0039] Between the two wings (2) of the U-shaped profile (1) is located an inner support profile (4) that configures a central housing (5) and two lateral housings (6) on the sides of the central housing (5) with two recesses (7) between two of the walls perpendicular to the web (3) and the wings (2) of the U-shaped profile (1). It should be noted that the central housing (5) is somewhat larger than the two lateral housings (6) located at the sides of the central housing (5).

[0040] Between the two wings (2) of the U-shaped profile (1), the bearing system for a slide, which is the object matter of the invention, comprises a sliding profile (8), which is the pane profile of the slide, such that the sliding profile (8) comprises two housings (9) which are located opposite to the lateral housings (6) of said U-shaped profile (1).

[0041] The web (3) of the bearing system for a slide, which is the object matter of the invention, in the preferred embodiment of the invention, is a double wall with an inner recess (18).

[0042] Once the geometry of a part of the bearing system for a slide, which is the object matter of the invention, has been defined, it will now be described which elements are used for the two embodiments.

[0043] In the embodiment for mounting with bearing in the frame, the central housing (5) is covered with a central cover (10) while the lateral housings (6) are provided with a plurality of bearings (11).

[0044] In this embodiment, the housings (9) of the sliding profile (8), serve to house one rail (12) each, such that the slide is supported on the plurality of bearings (11) through the rails (12).

[0045] In the embodiment for mounting with bearing on the pane, a rail (12) located in a longitudinal slot (13) of the aforementioned central housing (5) is located in the central housing (5). The housings (9) of the sliding profile (8) accommodate an intermediate piece (14), which has a plurality of longitudinal bearings (11) located in correspondence with the central housing (5) of the U-shaped profile (1). Therefore, in this embodiment, the system has an intermediate piece (14) that acts as a slider on which the slide pane is supported, since the bearings (11) are supported on the profile located inside the central housing (5) of the inner support profile (4).

[0046] For fixing the central cover (10) on the central housing (5) the central cover (10) comprises two protrusions (15) with flanges (16) at the end which are fixed on two projections (17) located inside the central housing (5).

[0047] Both the embodiment of the bearing system for mounting with bearing on the frame and for mounting with bearing on the pane described above can be reproduced in parallel so that the system supports more than one pane of the slide.
