Abstract:
A portable remotely controlled automatic door closing apparatus enables the door of a room or office to be closed from a remote location within the room or office by transmitting a signal to an actuator which exerts a force on the door to move it from an opened position to a closed position. The apparatus comprises a battery or AC powered motor which moves a lever arm into engagement with the door to rotate the door about its hinges from the open to the closed position. The apparatus is free standing and immobilized on the floor in a non-connected relationship thereto between an adjacent wall and the door in its open position. The apparatus is immobilized to prevent slipping by a floor-engaging mechanism, such as an adhesive, an anti-skid rubber material, or suction cups, or carpet engaging projections.
Abstract:
An automatic sliding door operator includes a top door operator and a bottom door operator, each operator having a motor driven sprocket driving a tooth belt to which the sliding doors are attached, the motors being separately driven in a position-synchronized fashion in response to related encoders connected with each motor to provide positional information.
Abstract:
There is disclosed an electro-mechanical door opening and closing device which is adapted to be retro-fitted onto an existing manually operated sliding door system. The sliding door system has a stationary panel and a movable panel and the system is installed in a wall of a building. A stationary portion includes the stationary panel, the door frame and the building adjacent to the door frame. The device includes a reversible motor, a bracket or handle and a control system. The reversible motor is attachable to one of the stationary portion and the movable panel. The bracket is attachable to the other of the stationary portion and the movable panel. The device includes a threaded rod operably connected to the reversible motor such that the rod may be rotated clockwise and counterclockwise. The rod is also movably connected to the bracket and rotation of the rod clockwise and counterclockwise causes the bracket to move towards and away from the motor thereby opening and closing the sliding panel. Combined the rod and bracket is similar to a power screw. The control system is operably connected to the reversible motor to control activation, direction and deactivation of the motor. Preferably the bracket includes a disengagable coupling mechanism with an engaged position, wherein the slidable panel is moved by the method of moving, and a release position, wherein the slidable panel is moved manually.
Abstract:
A programmable automatic window including a hollow frame with an aperture disposed therethrough; a window slidably secured within the aperture of the frame; a ball screw mechanism disposed within the frame and coupled to the window; a motor coupled to the ball screw mechanism and energizable with a positive polarity to cause rotation of the ball screw mechanism for allowing the window to be raised and energizable with a negative polarity to cause opposite rotation of the ball screw mechanism for allowing the window to be lowered; and motor logic switch circuitry for controlling the motor.
Abstract:
A door operator for garage doors is provided which includes a motor, a multiple segmented drive screw and a traveler coupled to and reciprocating along the multiple segmented drive screw. The drive screw segments have non-circular ends which are slidably coupled to each other through a complementary sleeve. Springs are used to bias the screw segments toward one another. The traveler includes a lubricating pad for lubricating the drive screw as it passes along.
Abstract:
A security mechanism for securing a movable closure supported within a frame, the closure being movable from a secured position to a plurality of unsecured positions, preferably having a securing element having at least one opening, a base element, a slider element movably mounted on the base element and a latch element comprising at least one locking latch pivotally attached to the base element. The locking latch preferably has a first cam surface for engaging a cam post located on the slider element and a second cam surface for engaging the opening of the securing element. When the closure is moved to its secured position, the second cam surface of the locking latch engages the opening of the securing element thereby causing the locking latch to pivot and lock to the opening of the securing element. When the closure is moved to an unsecured position, the slider element is moved along the base element away from the securing element, causing the first cam post of the slider element to engage the first cam surface of the locking latch, causing the locking latch to pivot and disengage the opening of the securing element, thereby unsecuring the closure. The security mechanism may be used in conjunction with an automatic garage door opener for automatically securing and unsecuring a garage door that is opened and closed by the automatic garage door opener.
Abstract:
An automotive vehicle body has a side opening that is opened and closed by a sliding door. The door is operated with a power drive mechanism that is pivotally mounted thereon and extends through the side opening. The power drive mechanism includes a reversible electric motor driven friction drive wheel and is spring biased to forcibly engage this wheel with a drive/guide track that is located beneath the vehicle floor and attached to the vehicle body. The friction drive wheel rides on the drive/guide track to open and close the door and also helps guide and stabilize its sliding movement. The spring load on the friction drive wheel is limited so as to provide sliding door operation with the motor under normal conditions and allow slippage at the friction drive wheel to cease door movement when the door encounters a physical object in the door opening.
Abstract:
A vehicular security system includes an electronic supervisory control unit which communicates with a remote signalling unit to provide both conventional alarm system functions typically associated with securing an unoccupied vehicle as well as anti-carjacking functions. The anti-carjacking functions may be remotely initiated by the vehicle operator who has been forcibly removed from the vehicle or passively initiated and include locking the vehicle doors, closing the vehicle windows, and thereafter disabling the engine to confine a criminal carjacking perpetrator within the vehicle to wait apprehension by law enforcement authorities.
Abstract:
Modular, powered closure apparatus for installation as a unit into an opening of a building. The apparatus includes a rigid framework to be secured to the building and closure panels, one of which is affixed to the framework and the other of which is slidable in the framework. The framework includes a housing which accommodates an electric motor and transmission means extending between the motor and second closure panel to selectively move the second closure panel between open and closed positions.
Abstract:
A van door slidable in tracks (16, 18 and 20). An operating module is mounted inside the van adjacent center track 18. A front cable attached to drive pulley (144) extends through guide assembly (54) to hinge and roller assemble (26). A rear cable attached to drive pulley (136) extends through guide assembly (56) to hinge and roller assembly (26). The drive pulleys (136 and 144) each have a large diameter spiral cable groove (164), a small diameter cable groove (208) and a transition cable groove (210). A motor rotates the drive pulleys. The small diameter cable grooves drive the door when the door is in the forward portion of the tracks. The large diameter spiral cable grooves drive the door when the door is in the center and rear portions of the track. Fixed idler rollers (226 and 254) are positioned relative to the cable drive pulleys to insure that the total cable in the continuous cable loop is substantially the same when the cable is driven by the small diameter cable grooves as when the cable is driven by the large diameter spiral cable grooves. A cable tension system (220) maintains cable tension. A slack cable take-up pulley (174) on the drive pulley (136) takes up slack cable to set cable tension and is then locked in position.
