Abstract:
An integrated gas strut actuator assembly particularly adapted for providing power actuation of a motor vehicle lift gate or other opening closure. The assembly integrates the function of a counterbalancing gas spring and that of a electrically powered actuator. The integrated gas strut assembly includes a gas charged cylinder, internal plunger and a threaded rod. Rotation of the threaded rod through a cable drive system causes the internal plunger to be advanced or retracted within the cylinder. Other features of the invention are various embodiments of couplers between the plunger and rod and connectors for connecting the assembly to the vehicle.

The carriage can be coupled to the synchronous drive member and to a bottom edge of a garage door. The operator can be coupled to the motor and can control the motor. The operator can be mounted vertically adjacent to the garage door when the garage door is in a closed position.
Abstract:
To provide a movable body driving device which has simple structure and is capable of moving a movable body in a certain direction and automatic drawer equipment. A movable body driving device is provided which comprises a roller 12 as a rotary member which is rotatably supported on an inner frame 11 as a supporting member and a motor 13 for rotating the roller 12. The roller 12 is brought in contact with the movable body, which is adapted to be movable in a certain direction, with predetermined force using elastic force of coil springs 21, 22, 23 as elastic members. The movable body is moved by frictional force between the movable body and the roller 12. Automatic drawer equipment employing the movable body driving device as its drawer driving mechanism is also provided.
Abstract:
An opening and closing control apparatus includes an automatic sliding door controller that controls a drive of an opening and closing driving mechanism. The automatic sliding door controller determines whether a request is a manual operating request or an automatic operating request on the basis of a signal from a press switch that is switched on by a press-on operation. In the case of the automatic operating request, the automatic sliding door controller is configured so that an automatic opening and closing determination process determines whether a request is an opening operating request or a closing operating request based on the detection of door state detection section, and an opening and closing process is then executed by operating the opening and closing driving mechanism based on the determination.
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:
A hinge assembly system (200) includes a hinge assembly structure (210) and a driving structure (220). The driving structure includes a driving shaft (50), a gear (60) and a sliding unit (70). The gear engages with the driving shaft in a manner such that the gear may drive the driving shaft to rotate but the driving shaft cannot drive the gear to rotate. The sliding unit includes a rack (72). The rack drives the gear to rotate. The driving structure provides a force allowing the hinge assembly structure to cause the hinge assembly to rotate.
Abstract:
An actuating mechanism for moving a vehicle body panel, such as tailgate, between an open and closed position includes a motor having a drive cable coupled to a rod and cylinder assembly to drive the tailgate between the open and closed positions. A mechanical control including a spring and pulley assembly is coupled to the drive cable to allow acceleration during opening or closing movement of the vehicle panel in response to a user input force.
Abstract:
An overhead door bracket for attachment of the main arm of an overhead door opener to a metal overhead door for the purpose of opening and closing the door. The inventive bracket has a relatively wide mounting plate which spans the distance between the portions of the sheet metal doors having existing reinforcing backing strips for mounting of the hinges connecting the metal panels of the door. The inventive bracket has conventional connecting tabs spaced and extending outward to receive the lower end of the main arm of an opening system. The tabs have pin receiver bores for pivotally securing the main arm to the bracket by means of a pin. The bracket mounting plate has three spaced rows of mounting holes for mounting the bracket to the upper panel of a hinged door panel, the mounting holes being proximate the respective ends of the bracket.
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:
A motorized operator for opening and closing a window sash relative to a window frame via an arm mechanism connected to the window frame and being adapted to be installed in a cavity defined in the window frame. The operator comprises a motor, a drive axle rotated by the motor, and first and second gears in meshed engagement. The first gear is mounted on the drive axle, while the second gear is mounted to the arm mechanism such that motorized rotation of the first gear rotatably drives the second gear thereby causing the arm mechanism to pivot for opening and closing the window sash. A manual operator is adapted to disengage the first and second gears from one another while becoming engaged to the second gear for manually rotating the second gear and so manually operate the arm mechanism. The manual operator comprises a handle and a manual actuator which includes a sprocket. The manual actuator is engageable on the drive axle for selectively displacing the first gear along the drive axle and cause the latter to disengage from the second gear while the sprocket of the manual actuator becomes engaged to the second gear, whereby a rotation of the manual actuator by way of the handle causes rotation of the sprocket and of the second gear and thus also a pivot of the arm mechanism.
