Abstract:
The invention relates to an emergency opening device for a folding hinged door (1) or a folding hinged gate using an electric motor drive mechanism with an electromagnetic engaging and disengaging clutch to open and close the wings (2, 2', 3, 3'). The invention is characterized in that an emergency opening device, which is assigned to the door, comprises an elastic traction or pressure mechanism (12, 15, 19, 22) which can be prestressed when closing the door and which engages in the driving axle (6, 6') of the outer wing (2, 2') or in the region of the main closing edge (7, 7') of the inner wing (3, 3').
Abstract:
Die Erfindung betrifft ein Scharnier (10) umfassend einen schwenkbaren Scharnierteil (12), einen feststehenden Scharnierteil (14) sowie ein spannbares Federelement, wobei der schwenkbare Scharnierteil (12) über ein Lager (16) am feststehenden Scharnierteil (14) um eine Schwenkachse (S) schwenkbar gelagert ist, und wobei das spannbare Federelement am Lager (16) angeordnet ist. Die Erfindung zeichnet sich dadurch aus, dass das Federelement als Flach-Spiralfeder (18) ausgebildet ist.
Abstract:
Support and operating device for sliding doors, in particular for wardrobe cabinets, wherein the doors (6) are moved from a closed and lowered position, to an open and raised position, shifted forward in relation to the closed doors, and vice versa. The device comprising one upper group of component parts and one lower group of component parts for each door (6), suitable for determining the movement of the door in such a way that it is always kept in its correct parallel and orthogonal position in all the shifted positions thereof.
Abstract:
The invention relates to a device (1) for moving a spring hinge (2), wherein the spring hinge (2) is connected, on the exit side, to a movable object, in particular a garage door. According to the invention, it is provided that the device (1) has at least a first set of rollers and a second set of rollers, each with at least two rollers (31, 32; 41, 42). The device (1) also has a drive means (7), which drives the rollers (31, 32; 41, 42) and shifts the spring hinge (2) in a first movement direction, in the direction of the object to be moved, or in a second movement direction. The device (1) creates a spring-hinge impact force of between 200 and 1000 newtons.
Abstract:
To avoid complex, larger, expensive automatic closers having ineffective braking of the slamming of the closure, a retraction device (10) including a drum (18), a coiled spring power assembly (22) for driving the drum, a centrifugal brake (24) for controlling the power assembly and the drum to eliminate slamming of the panel during closing, and a gear train transmission assembly (26) to connect the power assembly and the centrifugal brake. In one embodiment, the drum is a spool which carries a cable (20) to connect the panel to the retraction device. In another embodiment, the drum has a rim (131) which frictionally engages a frame (12a) supporting the closure. The centrifugal brake is adjustable to take into account a wide range of closure sizes and frictional conditions.
Abstract:
A safety mechanism for a closing installation, comprising a shaft and an element having teeth for cooperating with a catch which oscillates during rotational movements of the shaft. The mechanism further comprises a safety system including a ring for braking the oscillatory movement of the catch. The movement of the ring is controlled by a detecting system that detects the state of a spring which used to compensate the torque exerted on the shaft by the screen body.

Abstract:
The actuation device (3) includes a slidable carrier member (23) being biased for sliding movement, and the movement of the slidable carrier member is damped by means of a piston assembly (25) arranged displaceably in a cylinder (26). The piston assembly (25) is biased towards a position at the second end (28) of the cylinder (26), the first end (27) of the cylinder (26) is at least substantially closed, and the piston assembly (25) and/or the cylinder (26) is adapted to provide a leak opening small enough in order to create a pressure reduction inside the cylinder (26) between the first end (27) of the cylinder (26) and the piston assembly (25) when the piston assembly travels in the direction against the second end (28) of the cylinder (26).
Abstract:
The device has a jack to stress a hatch in the direction of its opening. A retractor cable (18) mounted on a plate (24) is wound on a winding drum (22). An engine (26) drives the drum in rotation around its axis. A ring gear (38), ball and piston (42) engage and release the drum with respect to an output shaft (26A). The shaft and rotation axis of the drum are aligned along a common axis (AC).
