A mechanism (A) that is used in moveable facades and shutter systems, garage doors and access systems is provided, allowing opening and closing of panels (P) positioned between rail profile (10) and lower rail (R).

A door assembly may include a first sidelite configured to be operably coupled to a first door jamb, a second sidelite configured to be operably coupled to a second door jamb where the first and second sidelites are disposed in a common plane and define a door opening between the first and second sidelites, a first sliding panel, a second sliding panel where the first and second sliding panels are movable from a closed position disposing the first and second sliding panels to block access through the door opening and an open position in which the first sliding panel is proximate the first sidelite and the second sliding panel is proximate the second sidelite, a first partial door panel, and a second partial door panel. The first and second sliding panels are disposed in a second plane parallel to the common plane in both the open and closed position. The first and second partial door panels are operably coupled to the first and second sidelites, respectively, via hinge assemblies. The first and second partial door panels have a closed state in which the first and second partial door panels are each disposed in the common plane blocking access through the door opening, and an open state in which the first and second partial door panels are each disposed out of the common plane.

A folding door structure is provided. The folding door structure includes an upright column, upper sliding bracket and a lower sliding bracket. The upright column is hinged to the door leaves. The folding door structure further includes a first lock component. The first lock component includes a first latch mounted inside the upright column, and both ends of which are extended out from the top and bottom of the upright column to insert into the upper slide and/or the lower slide. By providing a first lock component and an upright column, a first latch can lock the position of the upright column relative to a door frame in a direction of wind pressure. Accordingly, the stress environment of the upper sliding bracket and the lower sliding bracket is improved, and the reliability and the resistance to high wind pressure of the connection mounting structure between adjacent door leaves are improved.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for use with a bifold door for a modular wall panel system. The bifold door may include sliding door hardware coupled to a top portion of the bifold door configured to translate the bifold door within the door frame; a first plurality of hinges spaced apart vertically; and a second plurality of hinges spaced apart vertically between a first leaf and a second leaf.

An apparatus for an architectural opening may include a plurality of panels. At least one of the plurality of panels may include a frame including a pair of rails and a pair of stiles secured to the pair of rails at respective interfaces. The frame may define at least one opening. The interfaces may be sealed in a manner allowing a vacuum to be created inside at least a portion of the frame. An inset panel may be secured within the at least one opening. At least portions of the frame may be vacuum insulated. One or more hinges may secure a first panel of the plurality of panels to a second panel of the plurality of panels. The member may be a transparent or translucent window. The apparatus may be a garage door, an entry door, a window, or a storefront.

A fenestration unit configured to support a shootbolt locking system includes a panel including a panel frame with a stile member and a rail member that are attached by a corner joint. The stile and rail members are elongate and extend along a respective linear axis. The stile member is configured to receive and support at least part of the shootbolt locking system. The stile member includes a stile end with a first wall, and the rail member includes a rail end with a second wall. The corner joint includes a first bracket and a second bracket that are attached together. The first bracket is disposed within the stile end. The first wall is disposed between the first and second brackets. The second bracket projects away from the stile member, and the second bracket is received within the rail end and attached to the second wall.

In example implementations, an end cap is provided. The end cap includes a body portion comprising a top end, a bottom end, a front side, a back side, an inner side, and an outer side, a plurality of openings aligned between the inner side and the outer side to receive a mechanical fastener to connect to an end of the panel, a cam lever coupled to the top end, wherein the cam lever is to rotate around an axis to generate a lift force to lift and separate an adjacent panel, and a plurality of wheels coupled to the inner side, wherein the panel moves along a horizontal track via the plurality of wheels aligned with the horizontal track.

A bifold door includes a first hinge and a second hinge configured to rotatably couple the bifold door to a doorframe. The bifold door includes a slider configured to slide within a track of the doorframe as the bifold door is opened and closed. At least one of the first hinge, the second hinge, and the slider includes a spherical bearing and a pin.

A motor control system for a folding partition includes a data storage device and processing circuitry. The data storage device is configured to store a normal threshold profile to serve as a threshold for a measured current supplied to a motor to detect abnormal operation of the motor. The motor is configured to drive motion of the folding partition. The processing circuitry is operably coupled to the data storage device. The processing circuitry is configured to generate an adjusted threshold profile to serve as a threshold for the measured current supplied to the motor while moving the folding partition during a transition from an abnormal operational mode to the normal operational mode. The adjusted threshold profile is used for detecting additional abnormal operation of the motor. The processing circuitry is configured to generate the adjusted threshold profile by adjusting at least a portion of the normal threshold profile.

A movable wall system includes a plurality of movable wall panels including a first movable wall panel and a second moveable wall panel rotatably coupled together through at least one hinge. The movable wall system further includes a biasing system which biases the first movable wall panel and the second movable wall panel into an arrangement wherein a panel face of the first movable wall panel and a panel face of the second moveable wall panel are generally parallel.
