Abstract:
A moving apparatus forcefully moves a movable body backward up to the position at the end of backward movement after moving it backward to a prescribed position during backward movement, and it has a pair of sliders having first slider and a second slider and an impelling device. In the position before forward movement of the movable body, the second slider is locked against sliding and the first slider is made free to slide by catching a first engaging part, and in the position at the end of forward movement of the movable body, the first slider is locked against sliding by a first slide lock part in a state having released the first engaging part, and the second slider is made free to slide in a state having caught the second engaging part. In the course of operating the movable body to move backward up to a prescribed position, force is accumulated in the impelling device, and when it reaches the prescribed position, the second slider releases the second engaging part and is locked against sliding, and the first slider catches the first engaging part and is made free to slide.
Abstract:
In a drive device for opening and or closing the hatch of a motor vehicle, the drive including a spindle drive with a threaded spindle and a nut, with a clutch arranged between the rotary drive and the spindle drive, the clutch includes a shifting element, a clutch element, and a clutch disk non-rotatably connected to the threaded spindle. The shifting element is rotatably drivably connected to the rotary drive. The shifting element has an axially oriented helical first ramp and the clutch element has an axially oriented helical second ramp in opposed contact with said first ramp. Relative rotation of the shifting element and the clutch element causes relative axial displacement of the shifting element and the clutch element against a spring force. The clutch element has a clutch area movable into non-rotatable engagement with the clutch disk in response to the relative axial displacement of the shifting element and the clutch element such that the rotary drive for the spindle drive also operates the clutch.
Abstract:
A support post includes an inner post that supports rotation of an outer post. The inner post includes a journal assembly that supports and facilitates rotation about a central axis. The journal assembly that supports the outer post on the inner post includes a single ball bearing disposed along the axis of rotation. The inner post is fixed and supports a central post on which the ball bearing is supported. The outer post includes a sleeve that fits over the ball bearing and the central post. Support of the outer post along the central axis provides for improved mounting and gate support. An actuator can be utilized to automatically or remotely open the gate. The actuator is disposed within the inner post that drives rotation of the outer post. The outer post remains supported by the journal assembly and is rotated by the actuator with the inner post.
Abstract:
A system for re-synchronizing an access barrier with a barrier operator comprises an access barrier, and a barrier operator to profile and monitor the manual and automatic movements of the access barrier. The barrier operator comprises a controller, a memory, a motor pivot encoder, and a counting encoder. The memory contains a primary counter to store the distance measured by the counting encoder, while a secondary counter maintains a value equal to the travel of the access barrier as determined by a profiling operation initiated prior to operating the barrier operator. The controller takes into account the counts of the primary and secondary counters, along with the stored profile information, allows the re-synchronization system to determine the proper amount of movement to be applied to open or close the access barrier, in the event the access barrier has been manually moved.
Abstract:
A hinge assembly includes a central shaft (20), including an outer screw thread (221); a turning element (30), including a central hole (322) and a holding pin (314), an inner screw thread (323) formed at an inner surface of the central hole; a elastic means (40); a blocking element (50), defining a first through hole (51) and a second through hole (52); and a button (71), including a supporting pin (72). The central shaft extends through the central hole of the turning element, the first elastic element, and the first through hole of the blocking element in that order, the outer screw thread engages with the inner screw thread, and the holding pin of the turning element is received in the second through hole of the blocking element. The present invention enables a foldable electronic device to be opened simply by pressing the button.
Abstract:
The invention concerns an electromechanical drive for a door or the like, with a motor and a transmission, which are connected with each other, wherein a drive gear in the form of a gear wheel or the like is present on a drive shaft of the transmission and cooperates with means for moving the door or the like, preferably in or on a guide rail. The drive has a modular design, and it has a compact power unit that can be used with different types of mounting units for different doors. In this regard, the power unit is equipped with a standard mounting bracket. In addition, different housings can be used for different areas of application.
Abstract:
A system for raising and lowering a sectional overhead door between an open position and a closed position including, a counterbalance system adapted to be connected to the door, an operator motor assembly mounted proximate to the sectional overhead door in the closed position of the sectional overhead door, at least a portion of the operator motor assembly movable between a door operating position and a door locking position, and a locking assembly (370) having an engaged position to hold the motor assembly in the operating position and a disengaged position to release the motor assembly allowing it to move to the door locking position. The system may be provided with a remote light assembly having a switchable light source in sensing communication with the operator motor such that operation of the motor activates the light source. The system is further provided with a handle assembly (515) operatively engaging the motor assembly (40) and counterbalance system (30) to selectively disconnect the motor assembly (40) from the counterbalance system (30), whereby urging of a rotatable handle (516) to a disconnect position (516′) allows the door (D) to be manually freely moveable with the aid of the counterbalance system (30).
Abstract:
A sliding window panel assembly for a motor vehicle. The assembly includes a stationary window panel having an opening formed therein, at least one guide rail coupled to the stationary window panel below the opening and above a bottom edge of the stationary window panel, a shoe slidably received within the guide rail and configured to slidably move within the guide rail, a movable window panel mounted onto the shoe such that the movable window panel slidably moves with the shoe. The movable window panel can slidably move with respect to the stationary panel along a movable panel path. The lead screw drive unit engages the shoe and is adapted to move the shoe and the movable panel along the movable panel path within the guide rail.
Abstract:
A transmission joint with a coupling having frontal teeth (20,21) is inserted between an output shaft of a gear motor and a worm screw. A release element is associated in a radial way to the coupling so that the coupling can be manually released in an emergency. The release element includes an eccentric pin that engages the coupling element in a radial way so that the coupling element can be moved from an engagement position to a release position by being turned by a lock barrel (26) with its key.
