Abstract:
The invention relates to a device for activating a closure element (10) which is pivotably connected by a hinge-joint (12) to a rim (18) of an opening (16) to be closed. The device comprises an expandable activating element which functions between the rim (18) and the closure element (10). The invention is characterized in that the activating element is a bellows (26) which can be expanded by means of a pressure medium and which lies flat, when the closure member (10) is closed, between an area (30) of said closure element on the side of the hinge joint and a surface portion (28) of the rim (18) of the opening (16).

Abstract:
Die Erfindung betrifft eine Vorrichtung zum selbsttätigen Schließen eines Fensterkippflügels zum Schutz vor eindringendem Wasser, wobei der Fensterkippflügel in einem Lichtschacht anordenbar und, z.B. unterseitig, gelenkig angeschlagen vor einer entsprechenden Bauwerksöffnung angeordnet ist, weiterhin umfassend einen am Boden des Lichtschachts vorgesehenen Schwimm- oder Auftriebskörper mit Hebelmechanismus zum Aktivieren der Schließbewegung des Fensterkippflügels sowie Mitteln, insbesondere Federn, zum Erzeugen einer Schließkraft, welche auf den Fensterkippflügel einwirkt. Erfindungsgemäß ist oberhalb des Fensterkippflügels ein Auslösehebel mit Sperrklinke einerseits gelenkig am Fenstereinbaurahmen oder am Baukörper befestigt und andererseits mit dem Hebelmechanismus des Schwimm- oder Auftriebskörpers in Verbindung stehend. Die Sperrklinke hält den Fensterkippflügel an einer dort vorgesehenen Rastkante offen, wobei die Mittel zum Erzeugen der Schließkraft dem Auslösehebel benachbart angeordnet sind und die Schließkraft mittels Druckplatte von außen auf den Fensterkippflügel einwirkt. Im geöffneten Zustand des Fensterkippflügels ist die Schließkraft vom Auslösehebel über die Sperrklinke gegen den Baukörper so abgeleitet, dass der Kippflügelrahmen selbst kraftfrei bleibt. Mit dem Herausbewegen der Sperrklinke aus der Rastkante gelangt die Schließkraft über die Druckplatte verzögerungsfrei und schnell auf den Kippflügelrahmen zum Ausführen der Schließbewegung und zum Dichthalten des Fensters.
Abstract:
Disclosed is an emergency system for opening motor vehicle doors, especially doors that remain mechanically jammed following an accident. Said emergency system comprises a pneumatic energy accumulator/pneumatic energy accumulators (1) which is/are used as (an) executing element(s) for opening the door(s). Said energy accumulator (1) is fed by a pyrotechnic shell (2) or pyrotechnic shells (2, 3) that is/are controlled by means of an electronic detonation control system (8). The signal for the first detonation of the pyrotechnic shell (2) is supplied to the system (8) by a set of sensors (5, 6, 7) while the signal for the second detonation of the pyrotechnic shell (3) is supplied by a pressure transducer (9). The energy accumulator (1) is reset by means of an electrovalve (10).
Abstract:
The sliding door is associated with a carriage or support (5) by a telescopic guide, which extends parallel to the door and can be displaced on transversal guides (4) when it is actuated by a pneumatic piston (12) determining two positions of said carriage (5): a retracting position corresponding to the embedding of the door and an outward projecting position in which the door is also projected outward so that it can be displaced longitudinally towards the opening position. A linear motor (14) is mounted on the carriage-support (5) whose output is coupled to the door by means of an appropriate transmission to transmit its longitudinal movement to the door. The door thus describes an angular and straight trajectory, i.e. with an open segment of the door parallel to its own plane and a second segment perpendicular to the first segment and corresponding to the position of embedding.
Abstract:
The sliding door, by means of a telescoping guide, is related to a carriage or support (5) elongated parallel to the door, which may move along transversal guides (4) when acted upon by a pneumatic piston (12) which defines for said carriage (5) two positions, one of retraction corresponding to the door being locked in position, and another of outwards projection in which the door is also projected outwards so that it may move longitudinally to the open position. Said carriage-support (5) is provided with a linear motor (14), the output of which is coupled by means of a suitable transmission to the door itself, in order to supply its longitudinal motion to the latter. In this manner the door follows an angular and straight path, that is with an opening segment parallel to its plane and a second segment perpendicular to the former and which corresponds to the locking operation.
