摘要:
The invention pertains to a one- or two-leaf sliding, swinging or pocket door with electrical, pneumatic or hydraulic drive (10, 30), especially for vehicles. To avoid the risk of pinching due to built-in elements in the side closure region, the invention provides a spindle (12) to which the door leaf or leaves (1, 2) is/are connected by a nut (21, 32), with the spindle in the case of two-leaf doors being symmetrical to the center of the door and with the door drive producing either a rotational action in the spindle (12) or a linear action in the door (1). The spindle is fitted on one side with a free-wheel (23) and, preventing rotation of the fixed part of the free-wheel, an engaging and disengaging brake or coupling (24-28), thus avoiding a closing device in the side closure region.

The invention relates to the control of the movement of a sliding or swinging and sliding door (1) in its end closing area (x). The door leaf (82) can always move in the direction of closing by means of a free wheel (8) or similar but can only move in the direction of opening when a brake, coupling (9) or other fixing device for the part of the free wheel (8) that is located further away from the door leaf is released. A device for determining the position of the door is also provided. The invention is characterised in that any conventional anti-jamming measures that might be provided in the predetermined end closing area (x) are deactivated, in that as long as the door leaf (2) is located in the end closing area, the power to the door drive (4) and therefore, the closing force exerted on the door leaf, is reduced and in that the brake, coupling (9) or similar acting on part of the free wheel (8) that is located further away from the door leaf is released. The invention also relates to embodiments of this basic idea.
摘要:
Pneumatic or hydraulic drive for opening and closing doors, in which the rectilinear movement of a twin-action piston (5) actuated by a pressurized medium is converted into a rotary movement around a shaft (2) by means of a piston rod and a screw drive unit (3). A locking lever (10) mounted in a fixed position acts, under the effect of a spring (18), on a part (11) connected to the piston (5). The lever secures the piston in its end-of-travel position and is held in its open position against the force of another spring (15) by means of a hydraulic jack (14) actuated by a pressurized medium.

In a rotary drive, particularly for vehicle doors, the piston stroke of a piston-cylinder unit (5) is converted into a rotary motion by pairs of cylinders (14) which engage inclined slots (10, 11). The inclined slots are formed in cylinders (4, 6) coaxially arranged into each other, one of the cylinders being connected to the output shaft (7). The slots are axially orientated at their ends. The cover (2) of a pot-shaped housing (1) traversed by the output shaft (7) is provided with a collar (15) which projects outwardly and which surrounds the output shaft. The output shaft (7) is surrounded by a seal (17) of which the envelope (18) covers the outer side of the collar (15) and of which the edge (19) sealingly bears against the cover (2). The cover is provided on its side opposite to the collar with an axial groove (20) wherein the edge of the pot-shaped housing (1) is sealingly engaged.

摘要:
Dispositif d'entraînement pneumatique ou hydraulique pour l'ouverture et la fermeture des portes, dans lequel le mouvement rectiligne d'un piston (5) à double effet actionné par un milieu sous pression est transformé en un mouvement rotatif d'un arbre (2) par l'intermédiaire d'une tige de piston (6) et d'un organe à mouvement hélicoïdal (3). Un levier (10) de blocage monté pivotant en un endroit fixe agit, sous l'effet d'un ressort (18) en position fermée de la porte, sur une pièce (11) reliée au piston (5), assujettit le piston en fin de course et est maintenu dans sa position d'ouverture à l'encontre de la force d'un autre ressort (15) à l'aide d'un vérin hydraulique (14) actionné par un milieu sous pression.
摘要:
Dans un entraînement rotatif, en particulier pour portes de véhicules, la course des pistons d'une unité (5) de pistons et de cylindres de travail est convertie en un mouvement rotatif par des paires de cylindres (14) qui pénètrent dans des fentes inclinées (10, 11). Les fentes inclinées sont formées dans des cylindres (4, 6) agencés coaxialement l'un dans l'autre, un des cylindres étant relié à l'arbre de sortie (7). Les fentes sont orientées axialement à leurs extrémités. Le couvercle (2) d'un carter (1) en forme de pot traversé par l'arbre de sortie (7) présente un collet (15) qui fait saillie à l'extérieur et qui entoure l'arbre de sortie. L'arbre de sortie (7) est entouré d'une garniture étanche (17) dont l'enveloppe (18) recouvre le côté extérieur du collet (15) et dont le bord (19) est posé de façon étanche contre le couvercle (2). Le couvercle est pourvu, du côté opposé au collet, d'une rainure axiale (20) dans laquelle le bord du carter (1) en forme de pot s'insère de façon étanche.
