An inverted constant force window balance system has a carrier assembly including a housing with a first and a second housing wall, a coil spring with a free end, and a shoe assembly slidably coupled to the housing. The shoe assembly includes a first and a second shoe face. The housing slides between a first and a second position relative to the shoe assembly. When in the first position, the first and second housing walls are substantially non-coplanar with the first shoe face, and when in the second position, the first housing wall is substantially coplanar with the first shoe face and substantially non-coplanar with the second shoe face. The shoe assembly receives a pivot bar from a window sash and extends a brake upon rotation thereof. The balance system also includes a mounting bracket releasably coupled to the housing and coupled to the free end of the coil spring.

A door assembly of a vehicle includes a first door panel movable at least partially across a door opening from a first side of the door opening toward a second side of the door opening, a second door panel spaced apart from the first door panel and movable at least partially across the door opening from the first side toward the second side. A first magnetic element is located at the first door panel and a second magnetic element is located at the second door panel. The second magnetic element is interactive with the first magnetic element such that moving of the first door across the door opening causes movement of the second door panel across the door opening.

A door assembly of a vehicle includes a first door panel located in a first guide groove and movable at least partially across a door opening from a first side of the door opening toward a second side of the door opening, and a second door panel spaced apart from the first door panel and located in a second guide groove. The second door panel is movable at least partially across the door opening from the first side toward the second side. One or more first magnetic elements are located at the first door panel, and one or more second magnetic elements disposed at the second door panel. A magnetic force between the one or more first magnetic elements and the one or more second magnetic elements urges the first door panel into contact with a sidewall of the first guide groove.

A fitting frame having improved prefabricated rails, the fitting frame being implemented so as providable on an interior wall surface and the like, and includes: an upper frame body and a lower frame body which have facing surfaces respectively facing the upper end portion and the lower end portion of a door frame, and which are extrusion-molded in a longitudinal direction; and rail assemblies which are respectively fastened to the facing surfaces of the upper frame body and the lower frame body, and which guide the door frame so that same is mounted and slides thereon.

A touchless stall door opening and closing system includes a motor, a door pivot for pivoting a door between an open position and a closed position, a locking mechanism for locking the door when the door is in the closed position, and a microcontroller for receiving a signal from a first sensor to drive the motor for opening the door and for receiving a signal from a second sensor for actuating the locking mechanism for unlocking the door. A method for touchless operation of the door includes touchless opening of the door, touchless closing of the door, and touchless locking and unlocking of the door.

A roof assembly for a vehicle having an opening comprises a frame having two parallel longitudinal beams connected to a transverse beam. A drive system for a panel supports and moves the panel and includes a motor attached to the transverse beam, two substantially parallel guide rails attached to the longitudinal beams, and a support mechanism movably guided in the guide rails and operatively connected to the motor. The frame and the drive system as a unit are adapted to each other such that the drive system is partly inserted into the frame between the longitudinal beams and rotated such that the motor is on the lower side of the transverse beam of the frame and the guide rails at least partly positioned on a portion of the upper side of the longitudinal beams of the frame. There is also disclosed a method of assembling the roof assembly.

A sensor unit includes a garage door sensor, a frame configured to be secured at one side of an opening for a garage door, and a cover. The garage door sensor is connected to said frame. The cover is configured to accommodate at least a portion of said garage door sensor. The cover is removably secured to said garage door sensor, such as for periodic cleaning.

A control system for a sliding door operator system, having at least one sliding wing and a door header, includes a first sensor configured to define a first activation zone, a first wing presence zone and a first side presence zone, a second sensor configured to define a second activation zone, a second wing presence zone and a second side presence zone, and a controller configured to evaluate data from the first sensor and the second sensor for controlling operation of the at least one sliding wing in the sliding door operator system.

An overhead door frame assembly has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar and a support assembly and the upright columns and the upright I-bar are secured to a base adapted to be secured to a floor of a building. One of the splice assemblies is fastened to each upright column. Hinges pivotally mount an overhead door to the header to allow hydraulic cylinders connected to the support assemblies to move the overhead door to an open position and a closed 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.
