A sliding door assembly includes a track assembly defining a track surface and a slot; and a sliding door comprising a door body, a hinge rod, and a locking pin, each of the hinge rod and the locking pin extending from the door body and through the slot; wherein the sliding door is laterally slidable along the track assembly between a first position and a second position, and wherein each of the hinge rod and the locking pin slide laterally within the slot as the door slides between the first position and the second position.

A movable panel system is provided which has a guide provided with at least one rail, at least one glass panel and a carriage device slidingly supporting the at least one glass panel on the at least one rail. The carriage device has a carriage body engaged to the at least one glass panel, and a wheel group having at least two wheels, configured to slidingly engage the at least one rail, and a support frame, the at least two wheels being hinged, rotationally free, to the support frame. The carriage body and the support frame are mutually engaged by a hinge that allows reciprocal rotation.

A device for a closure drive assembly can include: a moveable trolley, the trolley configured for movement along a track or a rail under drive by a drive component to move a closure between an open position and a closed position, the trolley including a body having a guiding surface; a rotating body having one or more camming surfaces, rotation of the rotating body about a rotation axis being supported by the guiding surface; and a lever having a lever camming surface configured to engage with one or more of the camming surfaces of the rotating body, wherein the lever is associated with an engagement member such that rotation of the lever moves the lever camming surface along the one or more rotating body camming surfaces to displace the engagement member, and wherein the engagement member is arranged to provide selective engagement between the moveable trolley and the drive component.

A device for a track- or rail-mounted closure drive assembly can include a lever and cam arrangement configured to drive an engagement member between an engaged position and a disengaged position, the engaged position allowing motor drive of a closure and the disengaged position disconnecting the drive from the motor to the closure; and a rotating body including one or more camming surfaces and one or more peripheral surfaces, the peripheral surfaces including visual indicia to indicate to a user an orientation of the one or more camming surfaces and hence whether the engagement member is in the engaged position or the disengaged position.

The present disclosure may be embodied as a rotary actuator for lifting a load against gravity. The actuator includes a housing and a drive motor attached to the housing. The drive motor has a drive shaft. The drive shaft may be configured to be manually operated. A rotatable output shaft is attached to the housing and in mechanical communication with drive shaft. The actuator includes at least one spring which is configured to act on the output shaft to at least partially offset a weight of the load. The at least one spring may be a torsion spring. The at least one spring may be configured to unwind when the motor is driven to lift the load, and may be configured to be wound when the motor is driven to lower the load. The at least one spring may comprise a plurality of springs, such as torsion springs.

A casement window operator includes a linear input mechanism configured to be mounted to a stationary frame of a casement window, a linear to rotary motion converter operably coupled to an output of the linear input mechanism, a gear reducer operably coupled to an output of the rotary motion converter, and a sash arm operably coupled to an output of the gear reducer to rotate in conjunction with the output of the gear reducer. The sash arm is configured to extend from the stationary frame of the casement window to a rotatable window sash of the casement window.

A sliding door system includes an upper track; a lower track; a first sliding door comprising a first upper locking pin, a first lower locking assembly, and a first pivot assembly, the first pivot assembly engaging the upper track and the lower track, the first upper locking pin removably engaging the upper track, and the first lower locking assembly removably engaging the lower track; and a second sliding door comprising a second upper locking pin, a second lower locking assembly, and a second pivot assembly, the second pivot assembly engaging the upper track and the lower track, the second upper locking pin removably engaging the upper track, and the second lower locking assembly removably engaging the lower track.

A guide assembly includes a guide configured to be arranged on a stationary furniture part, a guide device configured to be connected to the movable furniture part, the guide device being displaceable relative to the guide, and an adjustment device for adjusting the guide relative to the stationary furniture part. The adjustment device includes a mounting device configured to be fixed to the stationary furniture part and a coupling device configured to be coupled to the guide. The preferably pivotally supported actuating element is for adjusting the coupling device relative to the mounting device. A securing device is provided for fixing the guide device relative to the guide in a securing position, and the securing device includes a securing body integrated into the adjustment device.

A movable barrier operator release mechanism includes an operator chassis having a first side. A shaft extending in a first direction from the first side of the chassis. A brake assembly coupled to the chassis and the first shaft extends into the brake assembly. The brake assembly includes a lever, mounted to a mounting plate of the brake assembly on end and freely movable at the other end. A cable attached to the lever that when pulled pivots the lever about its mounting point. When moved, the lever disengages the brake assembly allowing for free movement of the movable barrier.

A stopper for stopping rotation of a planar element with respect to a frame when the planar element is hinged to the frame, the stopper has a longitudinal axis and comprises: a locking bar having a toothed surface and received within an indentation, an operation handle for moving the locking bar out of the indentation, a locking spring having a locking tooth that is urged into the toothed surface, a releasing lever for releasing the locking tooth from the toothed surface, a retention spring for urging the locking bar into the indentation. A linear movement of the operation handle moves a portion of the locking bar out of the indentation, the locking bar abuts against the frame, and, the locking bar is fixed in its position by means of the locking tooth that is urged against the toothed surface.
