Abstract:
A motorized door opener for a vehicle (such as a military or security vehicle), featuring a sensor system that determines door position to prevent door damage while the opener is in operation. The opener features an offset gear system that effectively changes the door's rotation point. Mechanical advantage is gained by using a lengthened lever arm with the gear system, providing increased leverage and allowing the motor to provide enough force to open and close a heavily armored door. The opener can use existing door hinges, and can be provided so as not to protrude into the door space, in order to facilitate passenger and equipment entry/exit through the doors. A safety release mechanism is included in some embodiments, allowing the door to be manually opened or closed.
Abstract:
An assembly for an automatic garage door including a slide bar, a motor, and a drive assembly connected to the slide bar, and a tie connected to the garage door; the assembly including a first “C” bracket having a lower web, the first “C” bracket receiving the slide bar and the motor and drive assembly being operatively connected to the first “C” bracket for longitudinally moving the first “C” bracket; a second “C” bracket having a lower web, the second “C” bracket nestingly receiving the first “C” bracket, and the tie being further connected to the second “C” bracket; a latching mechanism incorporated within the first and second “C” brackets' lower webs, the latching mechanism being adapted for resisting movements of the first and second “C” brackets away from each other; and a third “C” bracket having lower web, the third “C” bracket nestingly receiving the second “C” bracket.
Abstract:
A window opening control assembly that includes a first member for attachment to one of a sash or a window frame. The first member includes a locking assembly. The window opening control assembly further includes a second member for attachment to the other of the sash or the window frame. The second member includes a flexible element that extends to the first member. The flexible element is secured by the locking assembly such that the flexible element is fed from the second member as the second member is moved away from the first member until the flexible element is anchored within the second element and the second element is correspondingly restrained from moving further away from the first member. The locking assembly is selectively unlocked to permit removal of the flexible element from the locking assembly and permit continued movement of the second member away from the first member.
Abstract:
A disclosed pin removal tool includes an elongate shank with a lift member extending orthogonally from a shank first end and a cylindrical shaft extending orthogonally from a shank second end, and also orthogonal to the lift member. The lift member has a blunt end fork with a pair of tongs forming a channel therebetween opening at a lift member distal end away from the shank.
Abstract:
A drive arrangement (10) has first and second wheels (12, 14) and an endless loop member (16). The path of the member (16) is defined in part by a third wheel (18), between the wheels (12, 14). The wheel (18) is movably mounted so that the length can be changed for the path of the member (16) as it passes around the wheel (18), between the wheels (12, -14). Accordingly, the member (16) can be tightened or slackened around the wheels (12, 14), so that the wheels (12, 14) can be coupled to convey drive from one to the other, through the member (16), or disengaged, so that drive is not conveyed.
Abstract:
The invention relates to a retraction device for a movable piece of furniture, having a pulling means windable on a roll, wherein an electric motor is provided for driving the roll, and having a coupling for releasably connecting the movable piece of furniture to the electric drive, having a first coupling part for fastening to the movable piece of furniture and a second coupling part connected to the pulling means, the first coupling part having an opening for at least the partial acceptance of the second coupling part, a locking mechanism being provided by which the first coupling part can be connected to the second coupling part in at least two different positions, the second coupling part being located at different depths in the opening in the two different positions.
Abstract:
A window assembly including a frame having an interior portion with an inner surface, and a sash having an interior portion and an exterior portion. The window assembly includes an operational mode and a wash mode. In the operational mode, the sash is movable from a closed position to a position in which the sash is generally perpendicular with the frame. In the wash mode, the sash is movable to a position where the exterior of the sash faces toward the interior frame.
Abstract:
A drive arrangement for a shaft, such as a shaft for driving a sectional door, roller shutter or the like, is in the form of a module, carried, in use, by the shaft and including a motor, a driven wheel fixed for rotation with the shaft and drivable, in use, by the motor, and clutch means and operable between the motor and the wheel. The module further includes brace means in the form of a limb attachable to a member which is fixed relative to the axis of the shaft, to brace the module against turning as the shaft is driven.
Abstract:
An electrically driven entryway activation system for opening and closing two spaced swinging doors hung on spaced rotating parallel door posts comprises a base plate extending between the door posts. Levers attached to each door post rotate in a plane parallel to the base plate. A low profile actuation system spaced between the levers comprises a center post, a sector gear journaled on the center post for rotation parallel to the base plate, and a low profile gearmotor mounted between the base plate and the sector gear. A low profile emergency manual mechanism is provided for unclutching the output pinion gear of the gearmotor.
Abstract:
A novel electrical floor-hinge device is provided, which contains an electrical motor and a speed reducing element configured on top of a platform element at a side on top of a body member. A vertical input shaft connected to the speed reducing element is joined to a lateral involute shaft via bevel gears. The involute shaft in turn engages a driven gear on a vertical output shaft. The top end of the output shaft is attached to a seat element whose top surface is fixedly joined to a lower inner corner of a door. By the electrical motor's driving the seat element into clockwise or counterclockwise swing, the door is closed or opened automatically. The speed reducing element can be easily replaced to fit doors of different weight.
