Abstract:
Mit diesem Antrieb werden die Oeffnungs - und die Schliess-bewegung einer horizontal bewegten Tür einer Aufzugskabine ausgeführt. Ein parallel zur Bewegungsrichtung der Kabinentür angeordneter Zahnriemen (7) ist durch einen Mitnehmerbügel (10) mit der Kabinentür verbunden. Der Antrieb des Zahnriemens (7) erfolgt durch eine auf einer an der Aufzugskabine angeordneten Achse (4.2) drehbar gelagerten Zahnrolle (4.3). Auf beiden Seiten der Zahnrolle (4.3) sind zum Spannen des Zahnriemens (7) Spannrollen (5.2, 6.2) vorgesehen. Die eine Spannrolle (5.2) ist an einem Betätigungshebel (5), die andere an einem Anschlaghebel (6) angeordnet. Beide Hebel sind auf der gleichen Achse (4.2) der Zahrolle (4.3) schwenkbar gelagert und durch eine Feder (20) miteinander verbunden. Wird die Schliessbewegung der Kabinentür durch einen Gegenstand oder einen Fahrgast unterbrochen. blockiert auch der Zahnriemen (7) des Türantriebs. Dabei wird der Antriebstrum (7.1) des Zahnriemens (7) durch den weiterlaufenden Motor (1) derart gespannt, dass die Spannrolle (5.2) des Betätigungshebels (5) nach oben gedrückt wird. Ein dabei durch den Betätigungsnocken (5.3) des Betätigungshebels (5) betätigter Umsteuerkontakt (24) schaltet die Drehrichtung des Motors (1) um. Die Kabinentür wird sofort wieder geöffnet.
Abstract:
A sliding window or sliding door arrangement having an external frame and a sliding element which is displaceably mounted in the external frame, a cable deflection system for tensioning and deflecting a cable, which includes a first cable deflection unit with a first cable deflection device, a second cable deflection unit with a second cable deflection device, and a guide channel which extends in the direction of gravitational force. The second cable deflection unit is held in the guide channel against gravitational force by a cable which is inserted into the cable deflection device, such that when the sliding element is displaced, the second cable deflection unit is displaced in the direction of gravitational force or in the opposing direction in the guide channel.

Abstract:
Barrier operator systems and methods of operation include a mechanical drive subsystem with a segmented and self-locking rail unit, rail mounting supports, belt and chain drive tensioning, and drive assembly carriage and interface; electronics and software routines for controlling operation of the various barrier operator functions; wall console communicating with the barrier operator; encryption and decryption of access codes; establishment and monitoring of travel limits and barrier speed and force profiles; thermal protection of barrier operator drive motors; and establishment and control of wireless communications from the barrier operator to accessories.
Abstract:
An automatic mechanism for operating sliding doors or windows, e.g., for fully or partially closing and fully or partially opening sliding doors or windows. Each of a plurality of sliding panes of doors or windows may comprise a corresponding automatic mechanism that may be operated independently of any of the other automatic mechanisms.
Abstract:
A tension applying apparatus includes a tension applying member applying a tensile force to a drive cable by being pressed against the drive cable, a biasing member generating a biasing force for pressing the tension applying member against the drive cable, a holding member including a guide portion which restricts a moving direction of the tension applying member and a housing member housing the tension applying member and the holding member. The holding member is configured to change the moving direction of the tension applying member which is guided by the guide portion in a state where the holding member including a rotation shaft is housed within the housing member. The housing member includes a holding structure holding the holding member at a position to which the holding member rotates in a direction where a pressing angle of the tension applying member relative to the drive cable becomes shallow.
Abstract:
Disclosed are alternate embodiments of various components of a barrier operator system. and methods of operation, including of the mechanical drive subsystem with segmented and self-locking rail unit, rail mounting supports, belt and chain drive tensioning, and drive assembly carriage and interface; the electronics and software routines for controlled operation of the various barrier operator functions; wall console communications with the barrier operator; encryption and decryption of access codes; establishment and monitoring of travel limits and barrier speed and force profiles; thermal protection of barrier operator drive motors; and establishment and control of communications from the barrier operator to accessories by way of a wireless adapter.
Abstract:
A belt tensioning motor mount comprises a support plate; a motor mount holding a motor, the motor mount slidably attached to the support plate; and a tension adjustor disposed on the support plate, the tension adjustor for adjusting the position of the motor mount along the support plate. In an embodiment, the motor mount includes an opening that accommodates a shaft of the motor, a driver pulley attached to the shaft. A belt is attached to the driver pulley on one side and a return pulley on an opposite side. The support plate is disposed adjacent a wall and above the belt which operates a plurality of sliding doors. In an embodiment, the tension adjustor includes a threaded bolt which, depending on which way turned, either causes the motor mount to slide in a first direction to increase belt tension or slide in a second direction to decrease belt tension.
Abstract:
In one aspect, a method of operating a movable barrier operator includes engaging a flexible driven member with a drive of the movable barrier operator. The method includes moving the flexible driven member in a first direction to move a movable barrier connected to the driven member and monitoring the position of the movable barrier. In response to the movable barrier reaching a given position, the driven member is moved in a second direction without moving the movable barrier to remove slack from the driven member. A movable barrier apparatus includes a movable barrier controller operatively coupled to a movable barrier operator. The movable barrier controller is configured to cause the movable barrier operator to reverse direction of a flexible driven member a distance after stopping movement of a movable barrier toward a limit position and without moving the movable barrier.
