Abstract:
Method of detecting obstructions encountered by a motorized door. The method includes providing a signal processor with one or more signals indicative of a predetermined door trajectory profile for at least a segment of a stroke of the door, the door trajectory profile providing an ideal speed and/or position versus an elapsed time since a beginning of the segment of the stroke. A door position signal from a position encoder for the door is received into the signal processor. The method includes generating one or more signals indicative of the velocity and/or position of the door from the door position signal and generating a trajectory discrepancy signal based on the velocity and/or position in relation to the ideal speed and/or position. A motor control signal is generated based on the trajectory discrepancy signal and the motor control signal is connected to motor control circuits connected to drive the motor for the door. The method further includes performing one or more tests on either the trajectory discrepancy, the velocity of the door or the position of the door to determine whether the door has encountered an obstruction, in which case an obstruction detection signal is generated. The obstruction detection signal is for stopping the door.

Abstract:
The door stopper of the present invention is of a construction such that a door contacting member fitted into a guide cylinder sunk vertically into the floor is allowed to be set in two positions, in a door contacting state in which it protrudes from the floor and in a housed state in which the top is substantially level with the floor. According to this construction, the floor is able to be substantially flat when the door stopper is not in use so that it does not become an obstruction to floor polishers and wheelchairs.
Abstract:
Method of facilitating release of an object caught by one or more closing transit vehicle door(s) in a motorized door system having a two stage lock, the two stage lock having a fully locked position and a pushback lock position. The method includes detecting the presence of the object by the effect of the object on either the position or the velocity of the door(s). The method also includes determining whether the door(s) are in a pushback range between the fully locked position and the pushback lock position. If an object is detected and the door(s) are in the pushback range, then one or more signals are supplied to a motor of the door(s) to move the door(s) in the door opening direction to or toward the pushback lock position.
Abstract:
A power drive moves a movable closure along a fixed path between an open and a closed position with respect to a portal defining a passage through a barrier. The power drive system is adapted for a sliding door mounted on at least one side of a vehicle for sliding movement forwardly and rearwardly of the vehicle. The system includes a reversible motor operable when actuated to selectively drive the door in opening or closing movement. A bracket is connected to the door for movement with respect to a guide connected to the side wall of the vehicle. The bracket is guided within the guide along a fixed path between the opened and closed positions of the door. An elongated drive member is connected to the bracket at one end for driving the bracket along the fixed path. The elongated drive member is slidably disposed within the guide. A translator mechanism operably engages with the drive member for powering movement of the drive member and connected bracket with respect to the guide along the fixed path. The translator mechanism can include a rotatable hub, operably engageable with the drive member, a gear transmission for driving the hub, and a clutch mechanism for connecting the motor to the transmission. The translator mechanism preferably has sufficient power to pull the sliding door into a primary latch position with respect to the corresponding portions of a latch mechanism attached to the door and frame defining the door opening.
Abstract:
A vehicle sliding door opening/closing control device comprises a control unit for outputting a standby signal and shifting into a standby mode when for a predetermined time there has been no user-operation input for causing a vehicle sliding door driven by a motor to be open/close-driven and shifting into an operating mode and performing control of the motor when there has been a user-operation input and a switch unit for shorting power input terminals of the motor on the basis of the standby signal. When there has been no user-operation input for causing the sliding door to be open/close-driven for a predetermined time, by shifting into a standby mode the power consumption of the control unit can be kept small and as a result it is possible to suppress the battery power consumption of the control unit. Also, in the standby mode, by shorting the power input terminals of the motor it is possible to keep the motor in a locked state and thereby apply braking to the sliding door. Therefore, when the vehicle has been stopped or parked on sloping ground such as an upward slope or a downward slope, it is possible to prevent the sliding door from starting to move under its own weight when it is half-open.
