  • Patent number: 11447997
    Abstract: 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.

  • Patent number: 10221605
    Abstract: An abutment element (B1, B2) is described adapted to be arranged on a profile (10) mounted on a furniture item, on the profile being able to slide a shock-absorber that is integral with a door and which is mounted to meet the abutment element to activate. The element has a portion (32, 52) slidably couplable to the profile so that the abutment element can slide on the profile without detaching; and a modifiable structure for creating a constraint to the sliding of the abutment element so as to make it integral with the profile. Thereby easy assembly and lack of screw-hole are assured.

  • Patent number: 8060983
    Abstract: A cushioning device for opening and closing of sliding shutters, particularly of sliding shutters for furniture, to be applied as a single item to each shutter or sliding partition, in order to be able to cushion an end part of their opening and closing movement. The cushioning device includes a cushioning box applied with brackets for support and sliding of the individual shutter; this box being equipped with two opposing braking devices of a rotary type, whose toothed hub directly meshes with a rack fixed to the box, each braking device being joined to its own slider guided by the box and being joined at one end by an elastic device with its opposite end joined to the other slider, both sliders being equipped with a hook for activating and deactivating the corresponding action of the final section of travel to be cushioned.

  • Publication number: 20100199563
    Abstract: The invention regards to a mechanism for the aligned closure of sliding doors (1-3), in particular for furniture or compartments (V1-V3) with two or more doors, with a sliding door (1, 2 or 3) for each compartment, and where each compartment opens by sliding and overlapping of one door with one of the adjacent doors and closes in alignment with the adjacent doors. The mechanism consists of a single bracket (10) for each door, one end of the bracket (10) being fixed on the door, and its opposite end being equipped with a first sensing bearing (13) to run along a cam guide (70), said bracket (10) being suitable for inclination and transversal movement with a carriage (30), which also allows it to slide along a rail (50) to be positioned on the upper surface of the compartments. The carriage (30) can be adjusted transversally and the bracket (10) can move axially in relation to the carriage (30).

  • Patent number: 7647728
    Abstract: Sliding doors, e.g., for pieces of furniture, particularly of the kind with two shutters and reduced height, having coplanar closing and opening by overlapping of the shutters. Support and translation of each shutter is provided by a respective clamp placed on the edge of the outer side, the clamp being linked to a pair of little carriages that can slide transversally with respect to the same shutter, because they are supported and guided by a respective carriage, which in turn can slide longitudinally along the edge of an opening, the respective carriage being led by a rail and control tracks, and engaged by a loose roller that constrains the respective carriage into a couple of longitudinal cams or grooves.

  • Patent number: 7441372
    Abstract: A balancing and equilibration device for suspended elements, e.g. doors, pieces of furniture, and windows that can be moved vertically, to allow their easy movement and balanced positioning at any point of their vertical travel. Supporting ropes are wound up to be translated in spiroid rims of a pair of opposing pulleys, the pulleys being integral with each other via a shaft rotatable on a bearing structure. The shaft is concentric to a helical spring that includes one end integral with the shaft and another end integral with a friction disc that can be blocked to its support to block the other end of the spring, whose opposite side is bound to turn with the shaft to increase or decrease its torsion reaction with changing movement of the pulleys, to assure balancing of the balanced translation of the element on a frame to be vertically covered or uncovered.
