Device for the opening, the displacement and the water closure of leaves of sliding leaves. (Machine-translation by Google Translate, not legally binding)
Device for the opening, sliding and sealing of sliding leaves, of the type comprising a drive mechanism; closing organs; rolling elements, constituted by a lower rail fixed to the ground and by wheels that support the leaf and that slide on the lower rail; an upper guide rail, which cooperates with corresponding guiding means located on the upper edge of the blade and suitable sealing means, characterized in that said operating mechanism comprises a handle and a preselector, of which the first acts on a gear wheel, which in turn acts on a first rack which, by means of bars, transmits a tension or thrust load on a set of levers arranged longitudinally on the upper edge of the moving leaf, so that it allows the light to tilt thereof over its support of the lower edge, which is carried out by the wheels resting on the lower rail, the handle being able to adopt three consecutive positions, of which the first is closing, the second, rotated at 90º with respect to the first, allows the displacement of the moving leaf as a slide, and the third, rotated 90º with respect to the second, allows the tilting of the mobile leaf. Il, all arranged in such a way that the handle, when actuating said first rack, moves in a vertical direction a short horizontal shank perpendicular to the vertical edge of the moving leaf adjacent to the frame when the leaf is in the closed position, so that the the aforementioned stem, which is housed in a hole made in the lower end of the aforementioned rack, pulls a strut which, by means of any angular transmission, provides a movement of horizontal translation to a piece of inverted u-section, provided between its branches side of a fixed pin passing through a guide groove made in a vertical longitudinal plate, which is capable of moving vertically inside said inverted u-piece and which is integral with a longitudinal weatherstrip constituting the sealing means of the lower edge of the blade having said guide slot a broken configuration, with two horizontal end sections at different heights, all arranged so that when the handle is in the closed position of the moving leaf, the carrier plate of the weatherstrip is forced to adopt the low position and the weatherstrip is applied with force against the lower crosspiece of the frame, in so much so that in the rest of the positions of the handle, said plate assumes high positions and, therefore, the weatherstrip is detached from the lower crosspiece of the frame.
