An anti-derailment system is described for a wheel which can roll on a track and is pivoted on a carriage which translatably supports a leaf of a piece of furniture. The system has a slider which is inseparably mountable or mounted on the track and is able to translate on the track independently of the carriage, and a constraint element for constraining the slider and at least one of the wheel, the carriage or the leaf to each other, so as to keep the wheel in condition of rolling on the track without derailing.

Provided is a device for opening and closing a sliding door, of which collinearly placed doors slide respectively to overlap each other such that the sliding door is opened or closed. The device includes a sliding portion formed on a surface on which doors come into contact with each other in order to prevent the doors from interfering with each other when the doors are opened; a pair of rail frames formed on a top surface of the furniture and provided with a rail protruding upwardly such that each door is slid forward and backward on the rail, the rail having both sides in which bending portions are formed; and rotational members, each of which is installed to one side of a connection bracket to be rotatable in a curved section of the bending portion while being lifted and slid on the rail.

A device for inhibiting the closing of a door that controls entry of an enclosure includes a first magnet disposed on a driven portion of the device and a second magnet disposed on a fixed portion of the enclosure. The first magnet and the second magnet are configured to be in register with each other as the door moves toward a closed position such that if the first magnet and the second magnet are in register with each other, a pole of the first magnet is in close proximity of a pole of the second magnet such that the first magnet and the second magnet react to each other to inhibit motion of the door towards the closed position.

A method for installing a guide assembly for a movable furniture part includes preferably carrying out chronologically in the following order: arranging on the furniture wall a first guide rail for guiding the movable furniture part, and arranging on a first longitudinal side of the first guide rail a drive device for influencing the movement of the movable furniture part on the furniture wall, the first guide rail and the drive device preferably being connected together. If the movable furniture part comprises at least two door leaves connected together in an articulated manner, arranging a second guide rail for guiding the movable furniture part on the furniture wall on a second longitudinal side of the first guide rail, the first guide rail and the second guide rail preferably being connected together in a form-fitting and/or movable manner in particular.

A dual sliding door apparatus incudes a rectangular shaped frame configured for attachment to two opposing walls and a floor, the frame creating an opening, a top of the frame comprising a first rail parallel to a second rail, a first glass door sized so as to cover about one half of the opening, a pair of roller wheels coupled to a top of the first door, the pair of roller wheels including a concave outer surface designed to mate with the first rail, such that the first door rolls on the first rail, a second glass door with a pair of roller wheels coupled to a top of the second door, a first stop coupled to an outer circumference of the first glass door, and a second stop coupled to an outer circumference of the second glass door.

A braking system for a sliding door system includes a receiver and a driving wedge. The receiver is at a fixed location along a travel path and includes a first braking surface. The driving wedge is attachable to a sliding door assembly of the sliding door system and includes a second braking surface. The driving wedge is movable along the travel path relative to the receiver between a disengaged configuration and an engaged configuration. In the disengaged configuration, the driving wedge is disengaged from the receiver, and, in the engaged configuration, the second braking surface frictionally engages the first braking surface.

An opening device (1) having an opening part (2) and a stationary part (4). The opening part (2) is movable relative to the stationary part (4) between a closed position and an open position. The opening device further includes a device arranged to accompany the movement of the opening part. The accompanying device has a first part (10) secured to the opening part (2) and a second part (12) secured to the stationary part (4), with the first part (10) being movable relative to the second part (12). The accompanying device includes a safety blocking device (20) arranged to block the movement of the first part (10) relative to the second part (12) when an inertial force applied to the opening part (2) toward the open position is above a predetermined threshold force.

A damping or return device for sliding door leaves, particularly for furniture, which is constituted by a steel pin that slideably and axially interacts within a magnet constituted by a diametrically differently-polarized collar.

A damping or return device for sliding door leaves, particularly for furniture, or for drawers, which is constituted by a pin the shank of which is constituted by a diametrically differently-polarized magnet that slideably and axially interacts with a steel plate or a complementarily-shaped collar, which is made of steel and polygonal

A damping or return device for sliding door leaves or drawers, particularly for furniture, is provided. The device has a first trolley, which is associated with a door leaf and is slideable with respect to an item of furniture, by a diametrically differently-polarized magnet, which is associated with the first trolley or with the item of furniture, and by at least one steel plate, which is associated with the item of furniture or with the first trolley. The first trolley interacts selectively with at least one elastically compressible element which abuts, in opening and in closing, with an abutment element which is associated with and protrudes from the item of furniture.
