Abstract:
A control mechanism provides a clutch module for selective locking and unlocking of a drive shaft used to retract and extend the shade element between storage and extended positions. The clutch module includes a reciprocator element that engages a key extending from an outer surrounding housing. A locking member between the reciprocator element and a coupling element carried by the drive shaft selectively locks and unlocks rotational coupling between the reciprocator element and the coupling element, thus selectively locking and unlocking the drive shaft. A cushioning mechanism, a unidirectional dampening or frictional deceleration is provided for the drive shaft. The cushioning mechanism includes an impeller or rotor immersed in a cushion medium that impedes rotation of the rotor, and hence the drive shaft to which the rotor is coupled.

Abstract:
An access control apparatus for an access gate. The access gate typically has a rotator that is configured to rotate around a rotator axis at a first variable speed in a forward direction. The access control apparatus may include a transmission that typically has an input element that is operatively connected to the rotator. The input element is generally configured to rotate at an input speed that is proportional to the first variable speed. The transmission typically also has an output element that has an output speed that is higher than the input speed. The input element and the output element may rotate around a common transmission axis. A retardation mechanism may be employed. The retardation mechanism is typically configured to rotate around a retardation mechanism axis. Generally the retardation mechanism is operatively connected to the output element of the transmission and is configured to retard motion of the access gate in the forward direction when the first variable speed is above a control-limit speed. In many embodiments the transmission axis and the retardation mechanism axis are substantially co-axial. Some embodiments include a freewheel/catch mechanism that has an input connection that is operatively connected to the rotator. The input connection may be configured to engage an output connection when the rotator is rotated at the first variable speed in a forward direction and configured for substantially unrestricted rotation when the rotator is rotated in a reverse direction opposite the forward direction. The input element of the transmission is typically operatively connected to the output connection of the freewheel/catch mechanism.

Die Erfindung betrifft ein Antriebssystem (1) zur automatischen Betätigung eines Verschließteils (2), insbesondere einer Heckklappe oder eines Heckdeckels, eines Kraftfahrzeugs (3), mit einer antriebsseitig mit einem Elektromotor (11) und abtriebsseitig mit dem Verschließteil (2) gekoppelten Kupplungsvorrichtung (13), die ein erstes Reibschlusselement (22) aufweist, das gegen eine Berührungsfläche (28) eines feststehenden Bauteils (24) verspannbar ist, und die ein zweites Reibschlusselement (23) aufweist, das ein Antriebselement (20) mit einem Abtriebselement (25) koppelt und gegen eine Berührungsfläche (29) eines mit dem ersten Reibschlusselement (22) gekoppelten Übertragungselementes (21) verspannbar ist. Bei elektromotorischem Antrieb überträgt das zweite Reibschlusselement (23) das antriebsseitig erzeugte Drehmoment vom Antriebseiement (20) auf das Abtriebselement (25), während bei manueller Betätigung des Verschließteils (2) das Übertragungselement (21) das abtriebsseitig erzeugte Drehmoment auf das erste Reibungselement (22) überträgt und dessen Blockierung gegenüber der zugeordneten ersten Berührungsfläche (28) löst.
Abstract:
The present invention provides a self-closing hinge to provide automatic closing of a hinged member in a slow fashion. The invention includes a generally cylindrical outer casing or housing that partially encloses a rotatable shaft that may be secured to a hinged member to effect the rotation thereof. The shaft is disposed within a recess in a cylindrical coupler that is engaged by the shaft during rotation in a first direction - generally an "open" rotational direction - and that engages the shaft to rotate it in a second direction - generally a "closed" rotational direction. The coupler is secured to a torsional spring that acts against the open rotation of the shaft, forcing the coupler to rotate in a closed direction. A rotatable inner casing, may be disposed within the outer casing in close proximity thereto, such that a high viscosity fluid may be disposed therebetween.

Dadurch kann bei kompakter Bauweise ein automatischer Antrieb bereitgestellt werden.
Abstract:
Die Erfindung betrifft einen Türantrieb, insbesondere die Türverriegelung, von Schienenfahrzeugen, aufweisend einen Spindelantrieb, dessen Spindel mit einem Freilauf verbunden ist, der die Drehung der Spindel in der Richtung, die der Schliessrichtung der Tür entspricht, gestattet und die Drehung der Spindel in der Richtung, die der Öffnungsrichtung entspricht, verhindert, wobei der spindelferne Teil des Freilaufs (1) drehbar, aber durch eine von einem Hubmagneten (8) lüftbare Kupplung (3, 6) lösbar fixiert bezüglich einer Lüftungsvorrichtung (2) gelagert ist. Die Erfindung ist dadurch gekennzeichnet, dass die Bremse, Kupplung od.dgl. in ihrer Offenposition fixiert oder fixierbar ist, und dass ein Schliessmagnet vorgesehen ist. In einer ersten Variante ist die Kupplung (3, 6) durch ein Gestänge (9) betätigbar, und zwischen der gelüfteten Position des Gestänges (9) und der verriegelten Position des Gestänges (9) liegt eine Totpunktlage. In einer zweiten Variante wird die Offenposition durch einen Permanentmagneten gehalten.
Abstract:
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.
Abstract:
Rotary locks used on transit vehicle doors (2) when opened and closed by a rotating helical door drive member (40). In a preferred embodiment, a first lock utilizes a negative thread portion (51) of the helical drive (40). A second lock utilizes a rotating lock pawl (22) and stop (23). The drive (40) and lock can be used to operate door systems with and without separate door hangers. Compensation for camber variations in car structure is provided through the use of spherical mounts or drive member journals (35, 38).
