Abstract:
An object of the present invention is to provide an opening and closing apparatus with lock with a simple and compact arrangement that enables secure locking of slide- apart type sliding doors and enables opening and closing and closed locking of the sliding doors to be performed with a single actuator. An opening and closing apparatus with lock includes: a rack and pinion mechanism, for opening and closing a pair of slide-apart type sliding doors; an actuator, functioning as an opening/closing drive source; a locking mechanism enabling to lock the sliding doors in a fully closed position by constraining movements of locking members, fixed to the respective sliding doors; a switching mechanism for the locking mechanism; and a planetary gear mechanism, into which a driving force of the actuator is input and which is enabled to output the driving force to the pinion and to the switching mechanism. When the sliding doors are in the fully closed position, the driving force is output to the switching mechanism.
Abstract:
A rotary drive for swivel-mounted doors, in particular vehicle doors, with a rotatably mounted spindle (18) with two opposing, flat threads (62, 64), a cylinder (10) that concentrically surrounds the spindle (18) and that contains a piston (52) that can be moved within the cylinder and that is torque-proof, an opening in the axis line of the piston (52) through which the spindle (18) passes, and at least two rollers (58, 60) that are rotatably mounted in the piston (52) on either side of the spindle and that roll on both opposing flat threads (62, 64) when the piston (52) is moved.
Abstract:
A door system having a sectional door (D) moveable between an open position and a closed position, a track system (T, T1) guiding movement of the sectional door, and an operator system (10) driving movement of the sectional door, said operator system including a motor assembly (42) having an adjustable housing (48) and capable of pivotal movement to a door locking position, said adjustable housing having a base section (70), an extendable section (72), and a latching mechanism (100) for maintaining the extendable section in a desired position and for permitting selective axially repositioning of the extendable section relative to the base section.
Abstract:
An operator system for moving a barrier between limit positions, includes an operator motor assembly mounted to the barrier, wherein the motor assembly is movable between an operating position (fig7) and a locking position (figδ) with the motor assembly blocking movement of the barrier. A bias assembly (170) allows the motor assembly to move toward the locking position (fig8) when either a predetermined force overcomes a biasing force, or when the barrier is moved to a closed position or when forced entry is imposed on the barrier. A modified blocker tab (238, 900) having a plurality of projections (902, 908) , and which is part of the motor assembly, allows the speed/angular position of the rotation of the motor assembly to be monitored with increased resolution.
Abstract:
The invention relates to a locking device for a swinging/sliding door, in particular for motor vehicles, cooperating with a guide rail (9), arranged along the bottom horizontal edge door leaf of the swinging/sliding door and provided in the region of the secondary closing edge and operated by a door actuator. The invention is characterised by a four-bar mechanism, preferably a parallelogram, formed by an essentially horizontally-arranged coupling member (1) and levers (2, 3) jointed thereto, whereby a crank (14) is provided on one of the arms (2, 3) into which an locking bolt extends, which may be displaced in to the crank by means of an actuator (6) driven by the door drive.
Abstract:
Ein Ausstellschiebetürsystem (1) für ein Fahrzeug, umfassend mindestens einen Türflügel (26a), der im geschlossenen Zustand außenhautbündig in der Türöffnung einsitzt und der sich in Offenstellung außenseitig vor der Fahrzeugwandung befindet und in dieser Stellung die Türöffnung freigibt, wobei der mindestens eine Türflügel (26a) an einem Schlitten (3) angeordnet ist, wobei der Schlitten (3) Längsführungs-mittel (21) aufweist und in der Türöffnung im Kopfbereich durch eine Montageplatte (2) quer zur Fahrzeuglängsachse verschieblich aufnehmbar ist, wobei sowohl zum Antrieb des mindestens einen Türflügels (26a) als auch zur Verschiebung des Schlittens quer zur Fahrzeuglängsachse ein Antrieb (26) vorgesehen ist, wobei der Antrieb (10) einen Motor (11) und einen vom Motor angetriebenen Ketten- oder Riementrieb (14) umfasst, wobei der Riemen- oder Kettentrieb (14) eine Übersetzung (40) aufweist, wobei die Übersetzung (40) derart ausgebildet ist, dass während der Ausstellbewegung des Schlittens (3) die Ausstellbewegung langsam aber bei hohem Moment erfolgt, wobei nach Abschluss der Ausstellbewegung die seitliche Bewegung des mindestens einen Türflügels (26a) schneller als die Ausstellbewegung, aber bei geringerem Moment erfolgt.
Abstract:
Die Erfindung betrifft eine Schwenkschiebetür für Fahrzeuge zur Personenbeförderung mit zumindest einem Türblatt (1, 2), das auf einem Führungselement (5) verschiebbar ist, welches quer zur Ebene des Türblattes bewegbar ist und bei dem die Reaktionskraft einer Antriebsvorrichtung (29) das Führungselement quer zur Türblattebene bewegt. Die Erfindung ist dadurch gekennzeichnet:
daß das Gelenkviereck ein Gelenkparallelogramm ist, wobei auf den am Wagenkasten drehbar gelagerten, bevorzugt als Schwenkplatten (6) ausgebildeten Schenkeln auch der im wesentlichen parallel zum Führungselement (5) verlaufende Antrieb (29) und die Steuerarme (22) für das Verschwenken des Türbaumrohres (23) gelagert sind, und daß am Führungselement (5) eine Gleitführung (31) befestigt ist, die mittels eines Verbindungsgliedes, wie Rolle (32) od.dergl., das drehfest mit dem Türbaumrohr (23) verbunden ist, die Drehbewegung des Türbaumrohres mit der Ausstellbewegung des Führungselementes koreliert wird.
Abstract:
A swivel-sliding door system for a vehicle having at least one door leaf (1a,1b) situated in the vehicle wall (3) in the closed state, and situated on the outside in front of the vehicle wall in the open state while leaving a door opening (2) free, wherein drive means, as well as transverse guide means and longitudinal guide means are provided which enable a movement of the at least one door leaf transverse relative to the vehicle wall (3) and along the vehicle wall, wherein the drive means, the transverse guide means and the longitudinal guide means are combined into one complete operating unit (4) that can, by means of some suitable fasteners (5), be mounted as one whole in the vehicle and be coupled to the at least one door leaf (1a,1b), and wherein the operating unit (4) comprises a frame which, in assembled condition, is fixedly connected to the vehicle and an assembly which is movably provided in the frame and which comprises a drive motor (30) for the door leaf movements.
