Abstract:
A window, which may be a casement window, includes an opening control mechanism for limiting the amount that the sash of the window can be opened to control ventilation and as a child safety feature. In one configuration, the opening control mechanism includes a frame track and release assembly attached to the window frame and a sash arm assembly including an articulating sash arm attached to the sash of the window. The frame track and release assembly has a track and a roller on one end of the sash arm rides along the track as the window sash begins to open. At the end of the track, the roller engages and is restrained by a release arm or stop thereby preventing the sash from being opened further. A lever or a button operatively coupled to the release arm is disposed inside the dwelling and inside an insect screen of the window. The lever can be slid sideways and then pulled back in two distinct motions to release the roller to allow the sash to be opened beyond its restrained position. The button can be exposed by moving a hingable cover from over the button and the button pressed to release the roller. The sash arm and track re-engage automatically when the window sash is closed.
Abstract:
A home appliance includes an oven and a door positioned at the front of the oven. A hinge assembly secured to the door is configured to move the door about an axis relative to the front of the oven. The hinge assembly includes a shear pin and a spring configured to exert a shear force. The shear force exerted by the helical spring increases as the door is moved about the first axis, and the shear pin is configured to fracture when the door is moved to a predetermined position about the axis.
Abstract:
The subject of the invention is a door drive for a swing door of a passenger transport vehicle, comprising a rotary post, which is arranged at the vehicle, with at least one pivot arm for arrangement at a door leaf, wherein a motor is arranged in the rotary post and is connected with the rotary post, wherein at least one planetary transmission stage is provided for stepping down the rotational speed of the motor and wherein the pinion cage of the at least one planetary transmission stage comprises a rotary element, particularly a pinion, which is fixable.
Abstract:
A hand-pulling drive mechanism for an industrial door is installed on a motor end cover of the motor. The mechanism includes a hand drive device to operate manually and a shaft connected with the hand drive device. The mechanism farther includes a gear pair to change an engagement state and a disengagement state, a rotation propelling device connected with the shaft, and an eccentric pulling device including a shaft pin placed on the shaft and a torsion jacket pivotally connected to the shaft and rotated relative to the shaft pin. The gear pair includes a drive gear sleeved on the shaft for switching between the two states, and a follower gear secured to a motor shaft. The rotation propelling device is moveably connected with the drive gear. The torsion jacket and the drive gear jointly move to pull the torsion jacket through eccentric rotation of the shaft pin when the shaft is rotated, so that the drive gear moves in an axial direction and the follower drive engages with and disengages from the drive gear.
Abstract:
An electronically-activated roof access hatch is described that allows an operator to unlock the roof access hatch safely from the ground before ascending to the roof access hatch. The opening of the roof access hatch is controlled by a control panel that unlocks the roof access hatch and causes the roof access hatch to open.
Abstract:
A power operator assembly is provided for moving a sliding door between a sliding door of a motor vehicle between a closed position and an open position. The power operator assembly includes a guide rail fixedly secured to the motor vehicle and defining a rail length. A slide mechanism slidingly engages the guide rail. A drive is fixedly secured to the guide rail for selectively moving the slide mechanism along the guide rail in either direction. First and second cables each extend between the sliding door and the slide mechanism for moving the sliding door as the slide mechanism is driven along the guide rail. A compound pulley set is operatively connected to the drive and receives the first and second cables for powered movement of the sliding door a multiplied distance greater than the rail length as the slide mechanism is driven along the guide rail.
Abstract:
An actuating device for a movable component includes a reversible motorized drive for driving the movable component from a normal position into an open position, the movable component being uncouplable from the reversible motorized drive in its open position. The actuating device includes a driving element movably drivable by the reversible motorized drive and engages in a crank recess and extending along the path of motion of the movable component. A length of the crank recess corresponds at least to a path of motion of the driving element between its normal position and its open position or partially open position. After adjustably driving the movable component into its open position, the driving element may be returned by the reversible motorized drive into the normal position.
Abstract:
A mechanical arm system for opening a door includes an actuator assembly having an output shaft and an arm driven by the output shaft so as to move the door from a closed position toward an open position. The arm is free from contact with the door when the door moves from the open position to the closed position. The actuator assembly is mounted to a support member adjacent the door. The arm extends between the output shaft and the door. The arm may be moveable between a position in which the arm contacts the door in the open position and a retracted position in which the arm is free from contact with the door in the closed position. The arm may be moved to the retracted position before the door reaches the open position so as to abort the opening of the door.
Abstract:
A drive arrangement for a shaft has a module carried by the shaft and including a motor, a driven wheel and a drive wheel. The motor, gearbox and drive wheel are carried on a slider plate which can slide transverse to the axis of the shaft. A front plate is fixed transverse to the axis of the shaft. A Bowden cable has its sheath attached to the front plate, and its inner cable attached to the slider plate, so that manipulation of the Bowden cable at a remote location allows force to be applied between the plates either tightening the belt to apply drive from the motor to the shaft, or releasing tension in the belt, to disengage the drive.
Abstract:
A system for use with a emergency exit door, comprising: a door opener including a stationary actuator with a movable distal arm for pushing the door open; a door strike mountable to a door frame having an opening to receive a latch of the emergency exit door, the electric door strike including a gate having a locked condition and a release condition; a controller connected to the door opener and the door strike; a remote activator having a triggered condition, which provides a signal to the controller when the remote activator is triggered, to unlock the gate and then the door opener, to open the emergency exit door.
