Abstract:
The present invention provides a control device at an opening/closing section of a vehicle and a method for controlling the opening/closing section of the vehicle for controlling a motor so that pinch at the opening/closing section is determined accurately while its constitution is very simple. The control device includes a pinch determination device that is mounted to a motor for opening/closing an opening/closing section of a vehicle and determines pinch of a foreign matter based on a change in the rotation number of the motor, and demagnetization pulse applying means for supplying power with reverse polarity to motor in a pulse-like manner at completion of the opening/closing.
Abstract:
Die Erfindung bezieht sich auf einen Klappenantrieb insbesondere für Klappen eines Kraftfahrzeugs, mit einem Antriebsmotor (4), von dem ein aus mehreren Elementen bestehender Antriebsstrang zu einem Bauteil der um eine Schwenkachse (3) schwenkbaren Klappe (1) führt, über den die Klappe (1) schwenkbar beaufschlagbar ist. Dabei ist die Klappe (1) in eine oder mehreren Öffnungspositionen von einer Haltevorrichtung haltbar und bei manueller Kraftbeaufschlagung in Öffnungs- und/oder Schließrichtung zumindest weitgehend frei bewegbar. In dem Übertragungskraftschluß des Antriebsstrangs sind wenigstens zwei Elemente des Antriebsstrangs entgegen einer bestimmten Federkraft relativ zueinander bewegbar, wobei der Bewegungsweg der zwei Elemente relativ zueinander von einem Sensor erfaßbar und ein Steuersignal erzeugbar ist, das einer Steuereinrichtung (5) zuleitbar ist durch die Haltevorrichtung freigebbar ansteuerbar ist.
Abstract:
A garage door operator (10) is disclosed to have a front coupling (60, 90) for a threaded screw (30) of the operator (10) and the rotor of the motor (20). The coupling (60, 90) includes a first coupling device (60) that is a unitary coupling member with opposing recesses (68B, 68A) for receiving each of the rotor shaft (26F) and an end portion (74) of the screw (30). The unitary coupling member thereby connects the screw (30) to the motor (20) for torque transmission from the motor. The second coupling device includes a thrust containment device (92) that is supported on the screw (30), and an intermediate assembly (94, 102, 104, 112, 110, 114) disposed between the thrust containment device and an end portion (44) of the guide rail (40) of the door operator. A retainer component (94) of the intermediate assembly restricts expansion of the thrust containment device.

Abstract:
A process for regulating the speed of rotation of an alternating current electric motor between two extreme angular positions of the rotor is characterized in that, on commissioning, the theoretical member (N) of complete periods (T) of the alternating current (1) to be supplied to the motor to drive it over such an angular displacement is determined, this theoretical number (N) is stored, on the basis of the chronological position (X) of these periods (T) complete in their total theoretical number (N), a table of the variations in the power supply to the motor required to ensure a predetermined speed is drawn up, in service, the actual instantaneous number (N') of complete periods of the alternating current between one extreme position (EI) and the other extreme position (EF) is counted, on the basis of the chronological position (X) of the actual member (N"), the power supply to the motor is aligned on the value given in the table for the corresponding thereotical member. The invention is applicable to the electrical and electrotechnical industries.
Abstract:
PURPOSE: A door opening and closing device for a railway vehicle is provided to obtain slide stroke of a door body and to make the device small by passing a connecting member adjacent to a driving pulley through an axial front side of a motor in opening and closing a door. CONSTITUTION: A door opening and closing device for a railway vehicle has an extension guide member(70) for guiding each door body(10A,10B) in the opening and closing direction of doors. The extension guide member is composed of a guide member for the vehicle(71) extended in the correspondent opening and closing direction and fixed to the vehicle; a guide member for the door extended in the same opening and closing direction and fixed to each door body; and a slide mechanism for connecting the guide members for both the vehicle and the door to slide in the longitudinal direction. The guide member for the vehicle is disposed right on an entrance(80) opened and closed by both door bodies.

PURPOSE: An automatic door and a control apparatus thereof are provided to prevent damage of a user or an object, while achieving improved efficiency of motor by removing influence of tensile force of a belt. CONSTITUTION: An automatic door comprises a door driving unit including a gear train(70). The door driving unit further includes a driving force transfer roller constituted by a permanent magnet or an electromagnet having a pinion gear for receiving driving force from a driving motor through the gear train; a carrier surface contacting the driving force transfer roller in such a manner that a magnetic reaction occurs between the carrier and the driving force transfer roller; a roller slider(92) having an end fixed to the carrier, and which is guided by the guide rail fixed in the upper portion of a door frame(10) and rolls by the linear motion which is converted from the rotating motion of the driving roller; and a slave roller slider arranged to be movable along the guide rail together with the roller slider.
Abstract:
PURPOSE: A double folding door having a secondary closing member is provided to enhance convenience for a user and adjust a door by having a secondary closing member pressing a resistance section to completely open the door when a door plate is electrically spread. CONSTITUTION: A double folding door having a secondary closing member comprises a door plate(10) and a secondary closing device(20). The door plate is connected to be consecutively folded by a hinge and installed inside a frame of a lattice shape. The secondary closing device generates a pressurization force so that the door plate is completely spread on a rail. The secondary closing device comprises an operation rod(22), a mover(38), a pressure piece(24), a driving pulley(30), a motor(32), and a key input unit.
