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:
In an electric motorized hinge apparatus, a biasing means maintains a concavo-convex engagement state between a third rotating member and a second engagement portion in a second rotating member, and thus the second rotating member rotates to follow the third rotating member. Furthermore, the biasing means maintains a concavo-convex holding state between a first engagement portion in the second rotating member and a first rotating member, and thus the first rotating member rotates to follow the second rotating member. Furthermore, as the first rotating member rotates, a lid portion rotates to follow it. During manual rotation of the lid portion, a motor is maintained in an off state and the second rotating member is kept at a stop by a lock means. Therefore, the engagement state at the first concavo-convex engagement part is released by the manual rotation of the lid portion, so that the lid portion can be freely rotated by hand.
Abstract:
A garage door drive assembly for moving a linkage arm connected to a garage door, the assembly being adapted for shipping in a partially assembled condition in at least a box for on-site installation, the assembly has a longitudinally-extending rail with laterally extending flanges. The assembly also has a carriage shaped to fit about the flanges. A drive mechanism is movably mounted to the rail. An anchor is coupled to the drive mechanism. The assembly also has a coupler with a selectively releasable connection to the anchor, a connector pivotably connectable to the linkage arm, and a detachable connection enabling the coupler to be fixedly secured to and carried by the carriage. The rail and the carriage may be shipped to the installation site in a box having a smaller cross-sectional profile than would be required to accommodate the carriage and coupling in their connected state.

Abstract:
The present system includes various mechanisms and devices which may be used to automatically open and close a window. In cooperation with the various mechanisms, a remote controller may be operated to accuate the mechanisms and devices without manual manipulation. In addition to the window mechanism being automatically operated, the system may also operate to lock the window structure to prevent unnecessary stress and overload to the motor, or to prevent unauthorized access and entry through the window.
Abstract:
A drive mechanism (14) for enabling driving and manual movement of a sliding side door (12). The assembly (14) has a track assembly (16) mounted to a vehicle body (10) at a predetermined height and a drive mechanism (18) mounted to the sliding side door (12) so as to be proximate to a door latching mechanism (19). The drive mechanism (18) has an input drive motor (22) driving an output gear assembly (24) engaging the track assembly (16) and a transmission gear assembly (23) with a sliding gear (50) which selectively couples the input drive motor (22) and an input gear assembly (23) to the output gear assembly (24) between an engaged position for driving movement or disengaged position for manual movement of the sliding side door (12). In this way, the slide side door (12) may be moved manually between open and closed positions without having to overcome the effort required of rotating the drive motor (22).
Abstract:
A retrofit power door assembly for installation on a manual door assembly. One aspect is related to a retrofit power door assembly having an axial operator. Another aspect relates to a retrofit power door assembly having a clutch with a manually engageable release member.
Abstract:
A manual release mechanism of a power actuated sliding door used typically for van applications, includes a bullet assembly interconnected between the ends of a pull member, or cable, of a powered pulley system. The bullet assembly engages and disengages within a passage of a hinge roller assembly which rides within a track of the vehicle. When disengaged, the door is free to slide without causing movement of the bullet assembly or powered pulley system. When engaged, the hinge roller assembly supports a pin which projects into the passage when in a rest position. If the bullet assembly is in the passage, the pin also projects into a groove of the bullet assembly, thereby, locking the bullet assembly within the passage and causing the hinge rolling assembly, which is pivotally connected to the door to move via operation of the powered pulley system. Disengagement of the pin or retraction of the passage way via a manual release handle causes the hinge roller assembly to disengage from the bullet assembly and therefore from the powered pulley system allowing for manual operation of the door independent of the pulley system.
Abstract:
The device (2), which is used to lock running gear (1) guided in a rail (5) and is or can be connected to the latter, has a body (21, 22) in which a locking pin (23) is displaceably mounted and, by means of a resilient element (24), is held resiliently in a first position, so that the locking pin (23) can be brought by the action of a force from the first position, in which it can engage in a locking element (36, 53) provided in the rail (5) or connected to the rail (5), into a second position, in which it is released from the engagement in the locking element (36, 53). The locking device (2), which is constructed simply and cost-effectively, therefore permits dividing elements (90), such as sliding doors, sliding counters or folding walls, which are guided by the running gear (1), to be closed off securely.
