摘要:
An emergency mechanism for manually opening a powered door that includes a hold-close latch that holds the door in a closed position. During the manual operation, a manually operated handle for actuating only the hold-closed latch is manually moved from a non-actuating position to an actuating position, which actuates the hold-close latch to release the door from the closed position. The handle is held in the actuating position until it is moved back to the non-actuating position during a subsequent powered operation, thus allowing a user to move the door to an opened position using both hands.

The disclosure concerns a method for controlling a sliding door arrangement of a motor vehicle, wherein the sliding door arrangement comprises a sliding door, a drive arrangement for motorized displacement of the sliding door, a control arrangement and a sensor arrangement with at least one sensor element, in particular implemented as a proximity sensor, where-in during operator event monitoring by means of the control arrangement the sensor signals of the sensor arrangement are monitored as to whether a predetermined operator event exists. It is proposed that the sensor arrangement is disposed at least partly in or on the sliding door and that opening the sliding door at least from a closed end position and/or closing the sliding door at least from an open end position is/are carried out by means of the drive arrangement depending on the result of the operator event monitoring.

A child safety device for a casement window includes a handle-driven gear reduction assembly having a sensor gear driven at a reduced speed relative to the handle, a sensor arm driven by the sensor gear of the gear reduction assembly and a slider movable between a stop position where rotation of the handle is prevented and a retracted position where rotation is allowed. A spring biases the slider towards the stop position. The slider is held in the retracted position by a catch and is released by the sensor arm to prevent further opening of the window when the sensor gear reaches a predetermined location. The safety device resets when the window is closed and can be overridden to allow full opening of the window by an adult. In the preferred design, the child safety device is a cover that can replace the cover of an existing casement window operator.

A motorized window operator for opening and closing a window having a mechanical drive system including a rotatable drive axle. A housing contains a motor which is in operative engagement with a gear train having an output gear. The output gear is engageable with an engagement means mounted upon the drive axle of the window. For engaging the output gear train with the engagement means, operation of the motor will rotate the drive axle to either open or close the window according to desire. The gear train is dissengageable from the engagement means which at the same time dissengages power to the motor. The drive axle can then be manually operated.

A lock and safety release for power operated doors of the type in which the door is normally connected to a door operator for movement thereby, and in which the connection of the door to the door operator can be released to enable manual movement of the door. The lock and safety release includes inner and outer emergency release handles at opposite sides of the door which are selectively operable to disconnect the door from the door operator, and a lock mechanism for locking the outer emergency handle to prevent its operation to disconnect the door from the door operator and to also disable the door operator to prevent powered movement of the door by the door operator. The inner release handle remains operative to disconnect the door from the door operator to enable manual operation of the door when the outer handle is locked and the power operator is disabled.

A foot operable door opener operates, without using one's hands, and without an electrical assist. The entrance cycle is initiated by stepping on a pedal. This force drives the pedal a ¼ turn, engaging a soft wheel to open the door. The pedal is hard linked to a crank arm which goes into a unidirectional crank shaft hub to turn the wheel. The downward pressure from the pedal pivots a ratcheted hinge connected to a bracketed spring-loaded wheel assembly to keep constant pressure to the ground. A gear box or multiple pumps of the pedal turns the wheel two or more 360 degrees rotations, opening the door to allow the entrant to pass until the foot pedal is dis-engaged. This action releases the ratcheting hinge mechanism, allowing the spring assisted wheel assemble to rotate to its original up position, releasing the wheel from the ground, allowing the door to close.

A composite pull-chain disc mechanism with brake function for a door operator comprises a torsional spring having de-twisting and twisting sides. The weight of a door curtain always acts on the de-twisting sides, so that the inner diameter of the torsional spring is induced to shrink to brake the rotation of the central shaft of the door operator. If twisting sides bears an external force, the inner diameter of the torsional spring is induced to enlarge to release braking of the central shaft. Furthermore, the composite pull-chain disc mechanism can be adapted to an electric door operator. In the case of detaching an electric motor mechanism during maintenance, the door operator can still be operated to open/close a door in a manual mode through the composite pull-chain disc mechanism.

The invention provides a control mechanism for opening/unlocking the garage door. In this manner, the Emergency Garage Door Arm Release allows consumers to open their garage door from the outside. A transmitter is a control device installed on the outside of the garage and features a keypad on which the user punches in their security code and then activates the emergency release button. Once activated the Emergency Garage Door Arm Release sends a current to the solenoid which then releases the pin thus allowing the garage door to pop open. Once released, the consumer manually opens or raises the garage door the rest of the way.

A separating device for a door leaf that is moveable overhead has a coupling element movable between a coupling position, in which the coupling element couples an output element of the drive device to the structural component, and a freewheeling position, in which the output element of the drive device is decoupled from the structural component. A locking member is provided which is movable between at least one release position, in which the locking member allows a movement of the coupling element into the freewheeling position, and at least one locking position, in which the locking member counteracts a movement of the coupling element into the freewheeling position. The locking member can be coupled to the drive device.
摘要:
An overhead door assembly designed particularly for use with vehicles such as railroad cars is disclosed. The door assembly is made up of an overhead door, vertical guide members for guiding the overhead door in the vertical direction and horizontal guide members for guiding the door in the horizontal direction. A motor is provided for driving the door between an open and a closed position. According to the invention, the door is first guided to a position directly in front of the door opening, but slightly spaced therefrom. The door is then moved horizontally in a plugging movement so as to securely close off the door opening.
