Abstract:
This invention relates to a type of safety door central release device which can be used to close the safety door automatically when electric power is disrupted. It comprises a cord that is tied to a mechanism having potential energy on one end, and extended to a far distance on the other end; a pair of crank arms of which one end molded as a grip and gripping the cord, and the other end is connected to a sliding bar, having potential energy which assists the grip in release the cord. When electric power is supplied, the sliding bar will be attracted to an electromagnet. As a result, while electric power is disrupted, the release device can immediately release the cord. Due to release of the cord, a brake for a door operator is released by means of the mechanism such that the safety door slides down and then it is closed.
Abstract:
A sliding door system comprising: a transom; at least one door leaf movable along the transom; an endless traction mechanism tension-resistantly connected to the at least one door leaf; a housing supported by the transom; a drive device for driving the endless traction mechanism, the drive device comprising a driven pulley supported by the housing and guiding the endless traction mechanism, the driven pulley having a flange facing the housing, and a locking element on the flange; a complementary locking element supported by the housing; and an electromechanical actuation device received in the housing. The electromechanical actuation device is operable to cause the complementary locking element to abut against the locking element to lock the at least one door leaf relative to the transom.
Abstract:
An electromechanical strut using an inline motor coupled to an inline planetary gear that are both mounted in the lower housing. The motor-gear assembly drives a worm gear and nut screw in the upper housing, extending or retracting an extensible shaft. Additionally, a power spring mounted coaxially around the worm gear provides a mechanical counterbalance to the weight of a lift gate on the shaft. As the shaft extends, the power spring uncoils, assisting the motor-gear assembly in raising the lift gate. Retracting the shaft recoils the spring, storing potential energy. Thus, a lower torque motor-gear assembly can be used, reducing the diameter of the lower housing. Preferably, the power spring can also drive the power screw to extend the strut even when the motor-gear assembly is not engaged.
Abstract:
A locking arrangement for a door system of a transit vehicle includes a combination of a lock mechanism and an electromagnetic brake. The lock mechanism enables positive locking of at least one door but does not require substantial contact between moving and stationary lock elements. The lock mechanism is connected with the manual release means for door opening during an emergency. The electromagnetic brake maintains door seal compression in the closed and locked condition which improves sealing capabilities and provides for reliable lock mechanism operation. Such combination provides locking redundancy and meets various requirements regarding annunciation and manual release operation.
Abstract:
The door-opening/closing apparatus includes a door, a driving unit that drives the door to close the door, a door movement detection unit that detects a movement of the door, an electrostatic switch that is mounted on the door for detecting a human's touching the door, and a judgment unit that judges whether the door is attempted to be closed. When the door movement detection unit detects a movement of the door, and when the electrostatic switch senses a human's touching the door, the judgment unit judges that the door is attempted to be closed, and then the driving unit drives to close the door.
Abstract:
A door apparatus includes a door having a hole and configured to be slidable with respect to a vehicle body, a member configured to open and close the hole, a first detector configured to detect a position of the member relative to the hole to determine an openness of the hole, a second detector configured to detect a position of the door relative to the body, and a unit configured to be activated to project from one to another of the body and the door, so as to abut on the another such that the door is stopped from sliding in an opening direction, when the openness is greater than a threshold, and the position is between a full-closed position and a midway position.
Abstract:
A drive for pivoting a flap arranged on a vehicle body about a pivot axis includes a non-self locking electric motor and a drive train connecting the motor to the flap. The motor can be switched between a driving active state and a non-driving inactive state, the motor being moveable in the inactive state at least substantially without any resistance. A braking device blocks the drive train in the inactive state of the drive motor and unblocks the drive train in the active state of the motor.
Abstract:
A control apparatus for opening/closing a vehicle door includes a door opening/closing mechanism for operating the vehicle door, a driving source for driving the door opening/closing mechanism, a connecting/disconnecting apparatus interposed between the door opening/closing mechanism and the driving source, and a controlling apparatus for controlling the connecting/disconnecting apparatus. The controlling apparatus for opening/closing the vehicle door includes a door movement-detecting apparatus for detecting a movement of the vehicle door. The controlling apparatus switches the connecting/disconnecting apparatus from a connected state to a disconnected state when the driving source is stopped during in an opening/closing operation of the vehicle door. The controlling apparatus performs a repetition mode, in which the connecting/disconnecting apparatus repeats the connected state and the disconnected state, when the movement of the vehicle door is detected in the disconnected state of the connecting/disconnecting apparatus.
Abstract:
An opening-closing device includes a driving source, an opening-closing mechanism for opening and closing an opening-closing member provided at a vehicle body by operation of the driving source, and a clutch positioned between the driving source and the opening-closing mechanism and sifting an energization state can transmit a driving force of the driving source to the opening-closing mechanism and a non-energization state can not transmit the drive force. The clutch includes a drive portion and a driven portion. The drive portion and the driven portion contact each other by a first load which can transmit the driving force from the driving source to the opening-closing mechanism when the clutch is the energization state. The drive portion and the driven portion contact each other by a second load which can not transmits the driving force from the driving source to opening-closing mechanism when the clutch is the non-energization state.
Abstract:
A motor vehicle contains a device (1) for controlling the shifting movement of a closure element by means of a shifting drive (5) fixed on the closure element. A transmission element (11) is mounted on a support console (7), which is connected fixedly to the closure element, which transmission element is movable relative to the support console (7), is mounted movably by a bearing region (13, 15) on a body region and is coupled by a coupling region (18), which faces away from the bearing region (13, 15), to the shifting drive (5) in order to transmit mechanical forces.
