摘要:
The invention relates to a device to be installed at a vehicle for performing an operation of opening and closing a panel door, comprising a slide base installed on the fixed base slidably in a vehicle width direction; and a door drive mechanism that has a drive wheel member to which a driving force is input, at least one follower wheel member provided in association with the drive wheel member, and an endless member that is looped around the drive wheel member and the follower wheel member so as to circle therearound, the door drive mechanism being installed on the slide base in the range from the front end portion of the entrance of the vehicle to the rear end portion of the entrance of the vehicle as viewed in the direction of the vehicle width so that the door drive mechanism slides with the slide base in the vehicle width direction.

Provided is an opening/closing apparatus with a lock capable of performing the opening/closing and closed lock of a sliding door by a single actuator and arbitrarily setting the timing of a lock operation. In the opening/closing apparatus with a lock, an electric motor is driven and the drive force of the electric motor is input to the sun gear of a planetary gear mechanism and output from the internal gear or the carrier. A pair of sliding doors are opened and closed by the drive force output from the internal gear. While the pair of sliding doors are at a fully closed position, the lock and lock-released states of a lock mechanism are switched by a lock restricting mechanism.

Provided is a small plug door device capable of performing an opening/closing operation and a plugging operation with a door drive mechanism for causing a force in a vehicle front-rear direction to act on a door, and further applicable also to a one-panel sliding door. A slide base 12 is installed slidably in a vehicle width direction relative to a fixed base 11. A door drive mechanism 13 for moving one door 104 in a vehicle front-rear direction via a connecting portion 19 has a drive portion 13a including an electric motor 21, a drive wheel member 13b, a follower wheel member 13c, and an endless member 13d, and is installed on the slide base 12. A guide portion 15 guides a shaft portion 14 provided on the connecting portion 19 so as to move the shaft portion 14 in a vehicle width direction. In a double-speed rail 16 in which a pinion 16c is disposed between two racks (16a, 16b), one rack 16b is connected to the slide base 12, the other rack 16a is connected to the door 104 side, and the pinion 16c is connected to the connecting portion 19.

The invention relates to a locking device for sliding doors, or for swinging-sliding doors of vehicles, particularly of rail vehicles, by means of which a locking pin (20) connected to a door leaf is fixed in the closed position thereof. The device is characterized in that in the closed position of the locking pin (2) the same is fixed in this position by a latch (3), a guide bar (5) connected to the latch (3) and having a notch (9) assumes a position in which a locking element (11) of a locking lever (10) projects into said notch (9), thus fixing the position of the guide bar (5), and the locking lever (10) in turn is held is said closed position by means of a toggle lever mechanism (13) that is located in the beyond dead point position.

There is disclosed a pneumatically operated barrier lock (10) comprising a body (12) and a primary locking pin (14) slidably mounted in a sleeve portion (16) of the body for movement along a path between an extended position for engaging a catch (130) and a retracted position for disengaging the catch (130). The lock (10) also includes a pneumatic cylinder (18) having one end (18A) adapted for connection to a first pressure source. The primary locking pin (14) extends through the pneumatic cylinder (18) and a piston (14E) is connected to the primary locking pin (14) at a position within the cylinder (18). Pressure injected into end (18A) of the pneumatic cylinder (18) biases the piston (14E) away therefrom and thereby biases the primary locking pin (14) toward the extended position. The opposite end (18B) of the pneumatic cylinder (18) is adapted for connection to a relatively low second pressure source (not shown). A low second pressure source connectable to end (18B) of the pneumatic cylinder (18) biases the piston (14E) away therefrom and generates a first biasing apparatus, in the form of a pneumatic spring, which biases the primary locking pin (14) toward the retracted position. A blocking member (20) is hingedly connected, about a pivot axis (22), to the body (12) and is selectively movable between a first position and a second position. In the first position, the blocking member (20) allows retraction of the primary locking pin (14) from the extended position to the retracted position under the bias of the pneumatic spring, hi the second position, the blocking member (20) engages an end of the primary locking pin (14) to prevent retraction of the primary locking pin (14) from the extended position to the retracted position.
摘要:
Verriegelungssystem für eine automatische Schwenkschiebetür, welche am Ende der Schliessbewegung eine mechanische Verriegelung und ein Andrücken an die Türdichtung ausführt. Eine zentrale Schwenk- und Verriegelungsmechanik (1) weist zueinander mit definiertem Winkel versetzte Hebel (4, 9) auf, welche, bedingt durch die Kurbeltriebcharakteristik, eine zeitlich gestaffelte Folge von Verriegelungs- und Andrückfunktionen, bzw. von Entriegelungs- und Loslösfunktionen ermöglichen.

Le dispositif de verrouillage (16) comporte une poignée extérieure et une poignée intérieure (20), un premier pêne (22), mobile entre une position en saillie et une position escamotée, et des premiers moyens de déplacement du premier pêne (22), activables uniquement par la poignée intérieure (20). Une première gâche (24) amovible est agencée en regard du premier pêne (22), et comporte une partie (26) mobile en basculement, indépendamment de la position du premier pêne (22). Un loquet (28) est mobile entre une première position (28A), dans laquelle il maintient la partie mobile (26) immobilisée de sorte qu'elle forme une butée pour le premier pêne (22) en position de saillie, et une seconde position (28B), dans laquelle il est à l'écart de la partie mobile (26) pour autoriser son libre basculement. Des moyens mécaniques de déplacement du loquet (28) sont prévus à l'extérieur de la cabine.
