COMPACT CLAMP FOR SLIDING GLASS DOORS WITH INCORPORATED DAMPER

Abstract

Disclosed is a new compact clamp for sliding glass doors, which includes two jaws, left jaw and right jaw. One of the jaws has a damper formed by a double-effect damper with gas and oil technology, using a cylinder containing a front gas chamber and a rear gas chamber which are located at the ends of the cylinder, and a central oil tank, the gas chambers and the oil tank being separated by a blind piston and an annular piston, which are both leak tight. In the central oil tank is disposed a non-leak tight damping piston that is connected to a rod of the damper and divides the tank into two oil chambers.

DESCRIPTION OF A PRACTICAL EXAMPLE

[0047] According to the drawings, the new compact clamp has two jaws, left jaw (1) and right jaw (2), which are connected by means of connecting screws and spacer screws, that allow to establish the adequate separation for their coupling to the glass door (3).

[0048] The left jaw (1) incorporates a damper (4) of double effect and technology gas and oil, while the right jaw (2) incorporates two wheels (5) for the displacement of the door by an aerial rail not illustrated.

[0049] The damper (4), it has a space formed by a cylinder (6) which distinguishes a front gas chamber (7) and a rear gas chamber (8) located at the ends of the cylinder, with the gas used nitrogen, and a central oil tank (9). The gas chambers (7 and 8) and the central oil tank (9) are separated by two watertight pistons, a blind floating piston (11) arranged between the rear gas chamber (8) and the central oil tank (9) and an annular floating piston (10), crossed by the shank (13) of the damper (4), arranged between the front gas chamber (7) and the central oil tank (9). Both pistons are watertight, so they are equipped with gaskets or sealing rings to avoid mixing gas and oil.

[0050] In the central oil tank (9) a third non-watertight damping piston (12) is available, which is connected to the damper shank (13) and which divides the central oil tank (9) into two chambers, in such a way that that with the movement of the piston forces a transfer of oil between chambers.

[0051] In the illustrative example, the double effect damper (4) whit gas and oil technology, is constituted as an independent element of the left jaw (1), so that said left jaw (1) has a cylindrical housing (14) in the one that inserts the cylinder (6) of the damper (4).

[0052] The shank (13) of the damper (4) has an oscillating hook (15) at its outer end, that runs to a guide (16) coupled to the left jaw (1).

[0053] This oscillating hook (15) is coupled to an end-of-stroke limit (17) and comprises blocking means (18) constituted by a protusion integrated in the oscillating hook (15) which is snapped into a seat provided in the guide (16) fixing the position of the damper in prestressed position.

[0054] The new compact clamp eliminates the rebound effect during deceleration of the door. This deceleration is produced in a harmonic and linear throughout its duration and allows to implement damping for opening and closing in sliding doors of small widths, as shows in FIG. 6.
