Abstract:
Drive system for moving a load along a curved path. The drive system includes a base for mounting the drive system, the base having a curved track for guiding the load along the curved path. There is a load engaging mechanism mounted on the base for movement relative to the base, the load engaging mechanism being for moving the load. The load engaging mechanism has a curved track engaging roller for engaging the curved track. A linear drive mechanism including a linearly driven member is mounted on the base. The linearly driven member includes a driving pivot. A drive link is attached to the driving pivot at a drive force receiving end of the drive link, the drive link including a driven pivot at a drive force communicating end of the drive link. The driven pivot is attached to the load engaging mechanism, whereby linear motion of the driving pivot causes motion of the load along the curved path.
Abstract:
A door speed is detected at every predetermined detecting time, and a door position is calculated at a timing detected the door speed. A target speed according to the door position is obtained by a map. A microcomputer calculates a speed difference &Dgr;VD between the target speed and the actual or present speed, and an acceleration/deceleration value &Dgr;VC such as the speed difference between the door speed at the last detecting time and the present detecting time. A duty increasing value and the decreasing value of a PWM duty command value for adjusting a torque of the motor are set based on the speed difference &Dgr;VD and the acceleration/deceleration value &Dgr;VC, the motor is driven by the PWM duty command value based on the duty increasing value and the decreasing value.
Abstract:
An activation device for a functional component of motor vehicle equipment having an electric motor includes a transmission device connected on the one hand to an output shaft of the motor and on the other hand to said functional component, so that the transmission device and the motor exert mutual forces upon one another, and a safety device adapted for modifying the electrical supply of the motor according to an operating parameter significant of said mutual forces. The motor is mounted on the equipment with at least one degree of movement with respect thereto, and the safety device has means of measuring the movement of the motor delivering measurement signals which determine the operating parameter. The activation device is particularly applicable to electric window winder or sun-roof systems.
Abstract:
The invention relates to a locking device and a door-drive device comprising a locking device for a door which can be secured against opening by unauthorized persons using force from the exterior. The locking device has a lever element consisting of two lever arms which pivot about a first pivoting shaft. A connecting element is hinged to the first lever arm for connecting the door and the second lever arm which has an engaging device.
Abstract:
A motorized sliding door mechanism for a motor vehicle having a body structure having a door opening and door. The mechanism includes a motor and drum assembly mounted on the door and a cable system including cable runs anchored to spaced points on the body structure. One cable run is wrapped in one direction around the drum and extends to an anchor point proximate the rear edge of the door opening of the body structure and a second run is wrapped around the drum in an opposite direction and extends to a point at the rear end of a rear guide track for the door which is mounted to the body structure. The cable runs extend from the drum to the anchor points via a pivotal hinge and a guide block at the rear of the door for guiding the sliding movement of the door.
Abstract:
A retrofit power door assembly for installation on a manual door assembly. One aspect is related to a retrofit power door assembly having an axial operator. Another aspect relates to a retrofit power door assembly having a clutch with a manually engageable release member.
Abstract:
A method of aligning a door operating system for operating an upwardly acting door including an operator that directly interrelates with a counterbalance assembly in the door operating system to move the door, where the operator is at least partially supported on the counterbalance assembly, loosely attaching the operator to a header adjacent the door, and, moving the door from a closed position to an open position and returning the door to the closed position to achieve alignment. Once aligned, the operator is securely attached to the header to maintain the system's alignment.
Abstract:
An apparatus for driving a motor that opens and closes the window of vehicle, for example, is so adapted that when the vehicle becomes submersed in the sea, a lake or a river, etc., the window is prevented from being closed owing to malfunctioning of a relay caused when a leakage current flows into an operating switch for opening and closing the window. When submersion is sensed and it is sensed that the motor is being rotated by a malfunction in a direction that closes the window, a relay for rotating the motor in the forward direction is actuated. This prevents the occurrence of a situation in which the motor is caused to rotate (especially in the direction that closes the window) regardless of the fact that the operating switch has not been operated.
Abstract:
A system for locking a driveable sliding door which comprises at least one moveable sliding panel and a swingable locking element which interlocks in its closed position with a first end with a lock pin. The system for locking is characterized by the second end of the swingable locking element being brought into contact with the sliding panel by opening or closing of the locking element so that the sliding panel can be driven into its opened or closed position.
Abstract:
A security entrance system for controlling access from an infeed area (98) to a protected area (100) has a structure (24) defining a chamber disposed between the infeed area and the protected area, with first doors (38) at the infeed end of the chamber second doors (46) at the protected area end of the chamber. A person entering the protected area must pass through a contraband detector such as a metal detector (90, 92) and enter the chamber. If no alarm was provided by the detector, the doors allow exit from the chamber into the protected area. If an alarm was provided by the metal detector, the doors only allow the person to pass back from the chamber into the infeed area and away from the protected area. The chamber is weighed or otherwise examined after at least some cycles of operation to assure that no contraband was concealed within the chamber.
