A bifold system, in at least one iteration, includes a frame having a jamb and a header; a track extending along the header; a first panel and a second panel each having a first side and a second side opposite the first side, the first panel being hinged to the jamb at the first side of the first panel to pivot about a vertical axis spaced with respect to the track; an intermediate hinge(s) connecting the second panel to the first panel, the intermediate hinge(s) enabling the panels to be opened and closed; a wheel connected towards the second side of the second panel, the wheel being rotatably and vertically mounted to travel along the track. When the panels are in the open configuration, the intermediate hinge(s) offsets the second side of the first panel from the first side of the second panel by a spacing in the forward direction.

A fitting for a folding door arranged on a furniture carcass has at least one first door leaf and a second door leaf connected thereto in a jointed manner. The fitting has a contact part arranged on the first or second door leaf, and the contact part is movably arranged between a contact position and a rest position on the first or second door leaf. In a closed position of the folding door, the contact part in the contact position can be brought into contact with the furniture carcass or a component of the furniture carcass and, in an open position of the folding door, the contact part in the rest position is movable in an intermediate chamber between the first and the second door leaf.

An example door system includes a panel to translate along a normal path between an open position and a closed position in front of a doorway in a wall. The door system further includes a first track to support the panel from an upper portion of the panel, and a second track to extend along the normal path proximate a lower portion of the panel. The door system also includes a spring to urge the panel toward the second track by a first force to maintain the panel in the normal path.

A furniture hinge includes a first fitting portion and a second fitting portion, the second fitting portion being pivotally connected to the first fitting portion by a hinge axis member. At least one of the fitting portions includes a base plate to be fixed to a furniture part, and an adjusting plate coupled to the hinge axis member, the adjusting plate being displaceably arranged on the base plate. A preferably pivotally mounted adjustment element can adjust a position of the adjusting plate relative to the base plate along a linear guide to adjust a position of the first fitting portion relative to the second fitting portion. A gap is formed between the first fitting portion and the second fitting portion in at least one relative position of the furniture hinge, and the adjustment element can be actuated by introducing a tool into the gap.

An ejecting device for a folding door is movably arranged on a furniture body. First and second door leaves of the folding door are interconnected in an articulated manner. The ejecting device has an ejecting element for folding open the folding door from a closed position, in which the door leaves are in a common closed plane, into an open position, in which the door leaves form an angle not equal to 180. The ejecting device has a first fitting part for mounting the ejecting device on the first door leaf. The ejecting element can move the second door leaf from the closed position into the open position by a scissor mechanism having at least two scissor levers, and is mounted between the first and second door leaves by an articulated connection formed by an intermediate lever connected in an articulated manner to the first and/or second scissor lever.

An arrangement for guiding a sliding door or folding-sliding door on a furniture wall, comprising a first guide system to be fastened on the furniture wall and a second guide system to be fastened on the furniture wall at a vertical distance from the first guide system. The two guide systems each have at least one guide and a guide body which is displaceably mounted on the guide, anda carrier on which the sliding door or folding-sliding door is to be fastened and which is connected in a movement-coupled manner to the two guide bodies of the guide systems. The carrier is assembled in the vertical direction from at least two carrier portions, and the at least two carrier portions can be releasably connected.

A guide system for guiding a furniture door, in particular a folding door or folding-sliding door, relative to a fixed furniture part includes a first guide rail and a running carriage which can be connected to the furniture door and which has a rolling body via which the running carriage is movably mounted on the first guide rail. The first guide rail has a running surface for the rolling body of the running carriage, and the first guide rail is assembled in the longitudinal direction from a first rail piece and one second rail piece. The two rail pieces can be releasably connected via a connecting piece on which there is formed a portion of the running surface for the rolling body of the running carriage.

A panel carriage hanger designed to travel slidable along a track, the panel carriage hanger having a cylindrical bore in a body, the bore having a lip substantially at a first end, the lip having a plurality of castellations. An anti-rotating sleeve having a plurality of castellations is located in the bore, and a biasing mechanism provides a substantially downwards force to the anti-rotating sleeve to mate the castellations. The anti-rotating sleeve movable substantially upwards from a first position in the bore where the castellations of the anti-rotating sleeve and the castellations of the bore mate such that the anti-rotating sleeve cannot rotate into a second position in the bore where the anti-rotating sleeve can rotate. A rod passing through and keyed to the anti-rotating sleeve such that the rod and the anti-rotating sleeve can rotate together, or both cannot rotate.

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.

A guide system includes a first guide rail, a guide carriage configured to be connected to the door wing and configured to run along the first guide rail, a second guide rail separate from the first guide rail, the second guide rail extending transversely to the first guide rail in a mounted condition, a carrier configured to be displaceable relative to the second guide rail, the guide carriage can be arranged on the carrier, and a transfer device for transferring the guide carriage at least from the first guide rail to the carrier. The transfer device includes a control curve configured to be bow-shaped at least over a region, so that the guide carriage, upon a transfer from the first guide rail to the carrier, can be moved at least over a region in a direction of the second guide rail.
