According to the invention in the first end position of the mounting profile (85) the lever units (51, 53; 52, 54) are aligned at least approximately parallel to the first and second connection bridge (58A, 58B) and are at least partially sunk into the centre bridge (55), which centre bridge (55) in this first end position of the mounting profile (85) is at least partially sunk into one of the first and second connection bridges (58A, 58B).

A rail for guiding a carriage of a furniture door, in which the rail has at least one mounting part. The at least one mounting part can be fastened to a furniture part, which is formed by a side wall of a piece of furniture, and can be releasably connected to a guide part. The guide part has at least one guide for the carriage.

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.

A folding door system comprising a concealed hinge, a first frame, and a second frame. The concealed hinge comprises a first hinge block having a slot formed therein and defining a first sliding portion, a second hinge block having a slot formed therein and defining a second sliding portion, a first linkage having a first connection pivotally secured to the first hinge block and a second connection slidably and pivotally secured within the second sliding portion, and a second linkage pivotally connected to the first linkage and having a third connection pivotally secured to the second hinge block and a fourth connection slidably and pivotally secured within the first sliding portion. The first hinge block is mounted to a side face of the first frame and the second hinge block is mounted to a side face of the second frame.

A guide system includes a first and second guide rail for guiding furniture parts. The second guide rail, in the mounted position, extends transversely relative to the first guide rail. A guiding device is connected to the first furniture part, and is movable relative to the first and second guide rails and has a fitting portion for fastening to the first furniture part. A carrier is displaceable relative to the second guide rail and is connected to a second fitting portion for fastening to the second furniture part. A first drive device moves the guiding device, starting from the second guide rail, at least over a region in a direction towards the first guide rail. The guide system has a second drive device for moving the guiding device, starting from the first guide rail, into a position in which the first and second fitting portion are aligned.

A latch assembly connected to the drive unit of a bi-fold door for retaining the bi-fold door secure to a building has elongated straps attached to rotatable latch drums mounted on the outer ends of the drive shaft of the drive unit. Lift drums powered by a motor driven gearbox raise and lower the bi-fold door. Latch assemblies having springs attached to the straps maintain tension on the straps during the opening and closing of the bi-fold door.

A guide system for guiding at least one door wing, in particular a folding-sliding-door, relative to a furniture carcass includes a first guide configured to guide the at least one door wing along a front face of the furniture carcass, and at least one second guide extending transversely to the first guide. The at least one second guide is configured to guide the at least one door wing along a sidewall of the furniture carcass, and the guide system includes at least one deflection element for supporting the at least one door wing at least in a transition region between the first and second guide. By the at least one deflection element, a collision between the furniture carcass, in particular the sidewall of the furniture carcass, and/or a cover arranged thereon and the at least one door wing can be prevented in the transition region.

An improved bi-fold shutter that includes a more efficient coupling mechanism at a hinge point suited to facilitate opening and closing the bi-fold shutter with greater ease. In one embodiment, the shutter may be designed for a window such that the shutter, when closed, is relatively close to the face of the associated window, and when open, forms an awning or overhang. The shutter includes an improved coupling mechanism at a hinge point between a first shutter portion and a second shutter portion. The improved hinge point shifts a direction of force needed to maneuver the shutter when moving the shutter from one position to another. The shift in opening and closing force directions improves the efficiency by which the shutter can be operated. In some embodiments, the shutter may be hand-operated. In other embodiments, the shutter may be powered.

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 guide system for guiding a door wing includes a first guide rail for guiding the door wing, and a second guide rail for guiding the door wing, with the second guide rail extending transversely relative to the first guide rail. A carrier displaceable along the second guide rail is connected or is to be connected to the door wing via at least three furniture hinges spaced from one another in the mounted condition. All furniture hinges, by which the door wing can be connected or is connected to the carrier in the mounted condition, are arranged or can be arranged on a common mounting member separate from the carrier. The mounting member is releasably connected to the carrier by a fastening device, and the mounting member is releasably connected to the carrier in a direction extending transversely to a longitudinal axis of the carrier.
