049139000 | OPTIONALLY MOVED, MANUALLY, OR BY MOTOR | 8 |
20080209811 | Door Drive Mechanism, Especially Revolving Door Drive Mechanism - A door operator includes a housing; a hydraulic compartment; a pressure compartment; a drive unit disposed in the housing and coupleable to a door via an output shaft, the drive unit being associated with the hydraulic compartment; a hydraulic pump in hydraulic connection with the hydraulic compartment and the pressure compartment; a motor in driving relationship with the hydraulic pump; and a spring force accumulator disposed in the housing. The spring force accumulator is associated with the pressure compartment and coupled to the drive unit. | 09-04-2008 |
20090000198 | Mechanical Arm System for Opening a Door - 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. | 01-01-2009 |
20130074409 | DOOR MACHINE HAVING CHAIN DISK LOCKING MECHANISM - A door machine having an electric motor and a chain disk locking mechanism. The chain disk locking mechanism includes a chain disk, an engaging rotary block, a stationary shaft and a plurality of moving pins. When the chain disk is pulled to rotate, the fixed pins of the chain disk press the moving pins so as to push the engaging rotary block to rotate with the stationary shaft together. When the stationary shaft is pulled to rotate, the engaging rotary block prohibits the moving pins from rotation. When the chain disk is pulled manually, the rolling door can be rolled upward or downward; when cease pulling the chain disk, braking is immediately effected so as to prevent the rolling door from moving upward or downward. Hence, the clutch mechanism can be omitted for cost saving and the structure of the mechanism can be simplified. | 03-28-2013 |
20150292257 | SLIDE WINDOW FOR VEHICLE - Provided herein is a slide window for a vehicle with which a slide panel can be smoothly moved to easily open and close an opening part without directly manipulating a slide panel | 10-15-2015 |
20160168898 | DEVICE FOR OPENING AND CLOSING VEHICLE DOOR | 06-16-2016 |
20160251887 | LINEAR DRIVE ACTUATOR FOR A MOVABLE VEHICLE PANEL | 09-01-2016 |
049140000 | With manually actuated operator | 2 |
20120240470 | ELECTRONICALLY POWERED DOOR WITH A MANUAL OVERRIDE MECHANISM - Embodiments of electric motor driven door or barrier opener with a manually operable drive for use in the event of a power failure are provided. The operator comprises a gear box drive connectable with an electric motor of said operator, said gear box comprising an output for drive coupling with said door to effect opening and closing of said door by said motor and a shaft that drive rotates when said motor rotates. The shaft carries a free wheeling manually rotatable drive wheel as said manually operable drive and useable in the event of power failure to effect manual drive rotation movement of said shaft to open and close the door via said gearbox. The manually rotatable drive wheel comprises at least one drive coupler mounted to move in a generally radially extending direction relative to a central longitudinal axis of said shaft so that manual rotation of said drive wheel in the event of a power failure will effect a movement of the at least one drive coupler in the generally radially extending direction to effect a drive coupling between said drive wheel and said shaft to input drive to said shaft to permit manual opening and or closing of said door. | 09-27-2012 |
20130247469 | COMPOSITE PULL-CHAIN DISC MECHANISM WITH BRAKE FUNCTION AND ELECTRIC DOOR OPERATOR INCORPORATED WITH THIS MECHANISM - 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. | 09-26-2013 |
