    Abstract: The present invention relates to a door operator device and sectional overhead door system with anti-pressure and anti-theft functions, principally having a small-tooth-difference reduction gear and a ratchet-locking device. An input end of the small-tooth-difference reduction gear is kinematically connected to an input shaft; an output end of the small-tooth-difference reduction gear is kinematically connected to a shaft; the small-tooth-difference reduction gear includes a ratchet on its outer circumference; the ratchet-locking device is controlled to selectively lock or unlock the ratchet. When the ratchet-locking device locks the ratchet, it can realize the anti-theft function; when the ratchet-locking device unlocks the ratchet, and the shaft is driven by the input shaft through the small-tooth-difference reduction gear, but the shaft decelerates, stops, or even reverses due to an obstacle encountered or other factors, the input shaft and the small-tooth-difference reduction gear will idle automatically.

    Abstract: A sliding door system for a building wall includes first and second wall parts having opposite first and second door openings respectively and separated by an intermediate space, first and second door leaves closing the first and second door openings respectively, a door leaf carrier slidable along the intermediate space by a linear guide device and on which the door leaves are pivotably mounted by a pivot mechanism, and a coupling device converting the carrier sliding movement into a rotational movement actuating the pivot mechanism so that the door leaves pivot relative to the door leaf carrier, the coupling device including a slotted component with a slot representing a desired relationship between the sliding movement and the rotational movement and a control lever coupling the slot to the pivot mechanism, and wherein the slotted component is mounted on at least one of the first and second wall parts.

    Abstract: A hinge includes: a first and second gear; a cover configured to attach the gears; a first outside surface associated with the first panel; a second outside surface associated with the second panel; wherein when the first and second outside surfaces are in a generally co-planer orientation, a tooth from one of the first and second gears fits next to a tooth from the other of the first and second gears to form a water shedding joint. A method of forming a hinge includes: extruding a gear together with a panel having a first outside surface; a second panel a second outside surface; wherein when the first and second outside surfaces are in a generally co-planer orientation, a tooth from one of the first and second gears fits next to a tooth from the other of the first and second gears to form a water shedding joint.

    Abstract: A one-way speed limiter includes a first housing including an inner surface. defining a speed limiter receiving zone. A second housing includes a flange and a second wall including an inner surface portion that includes a stop feature. A ball housing including a ball member is rotatably supported in the speed limiter receiving zone. The ball member selectively engages the stop feature. A friction clutch is disposed between the ball housing and the first housing. The friction clutch selectively retards rotation of the ball housing. A motor shaft is selectively rotatably connected to the ball housing. The motor shaft including a first end supported at the ball housing and a second end. The motor shaft is rotatable relative to the ball housing in a first direction and selectively rotatably constrained relative to the ball housing in a second direction to selectively engage the friction clutch.
