Abstract:
A folding and spreading system for a half spread folding comprises an upper and a lower guider for making the folding door move in a close or open direction; a first wire guider provided at the depth portion of each door leaf in a predetermined distance from a neighboring first wire guider, and a second wire guider installed coaxially to the first wire guider; a folding motor and a spreading motor provided at both end frames of the folding door, respectively, and having a reel at each rotational shaft of each motor; and a winding wire and a releasing wire extended diagonally through each of the wire guiders of each door leaf, respective end of the wires connected to the wire guider and to the reel of the motor, respectively, in order to fold and spread the adjacent two door leaves around the hinge.
Abstract:
An automotive power pivot door is powered by an electric motor through an electromagnetic clutch. A control device of the door has a control unit configured to carry out a routine which comprises de-energizing an electric motor and disengaging the clutch when the door is lifted up to a full-open position; detecting a moved distance by which the door moves down from the full-open position within a first predetermined time (t1) from the time on which the clutch is disengaged; engaging the clutch when the detected moved distance is equal to or greater than a first predetermined distance (L1); disengaging the clutch again when a second predetermined time (t2) passes from the time on which the clutch is engaged; repeating the process for engaging and disengaging the clutch while following the routine; and judging that the holder fails to operate when the frequency of the engaged condition of the clutch indicates a predetermined frequency.
Abstract:
A spindle and worm drive for adjusting devices, especially seat adjustment devices, window lifters and sliding roofs, in motor vehicles. The drive includes a fixed spindle or relatively fixed toothed rack which is secured to one of relatively two moving parts and gear elements mounted in a housing which includes at least two plates that can be secured to each other by plug-in connectors. The connectors are also configured as supporting joints that absorb the forces of the gear.
Abstract:
The device has at least one controllable divider element including a drive assembly guided within a track, the drive assembly being driven by an electric motor which is controllable by a central control unit and a local control unit, which units exchange data through an electric line located in the track and functioning as the power supply for the electric motor. According to the invention, a first direct voltage is provided in the central control unit, the voltage being connectable to the power supply line through a central switch which is actuated as a function of the data to be transmitted between the central and local control units, whereby, when the switch is opened, data are able to be transmitted from the local control unit to the central control unit. In addition, an especially advantageous initialization of the device is possible based on the method according to the invention.
Abstract:
The control device includes a switch (12) controlling the power supply to the motor and an actuator which actuates this switch by rotatably reacting against the moving object being restrained so as to cause said switch to be opened and to cut off the power supply to the motor. This actuator consists of a bistable mechanical device (11) capable of taking up a first state in which the switch (12) is closed and a second state in which the switch is open. The actuating device also comprises exclusively manual means, such as a cable (17) for putting the actuating device into its first state, this device being brought into its second state by reacting against the moving object.
Abstract:
An apparatus for automatically opening a swinging restroom door is provided. The apparatus comprises an actuator, a control unit, and a power assisted drive mechanism that can be connected to an existing door closing mechanism. The actuator comprises a proximity sensor and further comprises a series of iconic symbols corresponding to predetermined proximity zones. The control unit is in electronic communication with the actuator with which signals are exchanged. The power assisted drive mechanism is in electronic communication with the control unit and can be connected to an existing door closing mechanism wherein the actions of the door closing mechanism are reversed and the door is opened.
Abstract:
An emergency door opening actuator includes electrical switches that are at least one of normally open and normally closed. The electrical switches may be connected accordingly in parallel or in series to terminals of an overhead door operator. The terminals may correspond to a push button circuit, an obstruction sensing circuit, an alarm system circuit, and/or a door opening circuit. The emergency door opening actuator may take advantage of a protocol in the operator to cause the overhead door to open during an emergency condition to facilitate egress. Likewise, the emergency door opening actuator may cause that the overhead door cannot close by signaling the protocol in a predetermined way when the switches are actuated by an emergency condition. The electrical switches may be mechanically actuated when at least one fusible link is broken. The emergency door opening actuator may include an automatic mechanical stop and/or a test release mechanism.
Abstract:
A device for actuating the doors of vehicles, in particular of an aircraft. The device comprises a drive element, which co-operates with a door lock. A lifting motion of a shaft element and a subsequent rotational motion of a follower element are carried out in an actuation device by a drive element.
Abstract:
A vehicle door controlling apparatus comprises a connection locking mechanism between a swinging door and a sliding door for locking the two doors by connecting them to each other. The swinging door is capable of opening or closing the front side of a vehicle opening and the second door is capable of opening or closing the rear side of the opening. The vehicle door controlling apparatus further comprises an operating switch which requests the opening of the sliding door, a rotary switch which detects a lock state between the doors, and a latch switch and a pole switch which detect a lock state at the rear side of the sliding door. When the controller detects a request for opening the sliding door, a release actuator releases the lock state, electric current is applied to a sliding motor, and electrical operation of the sliding door starts.
Abstract:
A dual rack and pinion system is provided for a window lift mechanism. The window lift mechanism includes improved window brackets for simple mounting to a window. A modular frame design is provided to improve assembly of the window lift mechanism into the door of a vehicle. An improved assembly method is provided for the dual rack and pinion system. The system is also provided with a smart motor and incorporates resilient shock absorbers in the dual rack and pinion gear train to allow more time for the smart motor to detect and react to an obstruction in the window.
