US 9,752,367 B2 · Damping or return device for sliding door leaves

Abstract

A damping or return device for sliding door leaves, particularly for furniture, is provided. The device includes a rectilinear hollow body made of plastic material, which is slideably associated with a profile that is integral with the top of the piece of furniture and can be coupled automatically and with a snap action to an entrainer. The entainer is fixed to one of the door leaves by way of an adapted carriage. The rectilinear hollow body accommodates a bidirectional shock absorber and interacts selectively with a first or a second magnetized stroke limiting pivot which are associated with a first guide or with a second guide.

A damping or return device for sliding door leaves, particularly for furniture, comprising:

a rectilinear hollow body made of plastic material, which is slideably associated with a profile that is integral with a top of a piece of furniture and can be coupled automatically and with a snap action to an entrainer that is fixed to one of the door leaves by way of a carriage, the rectilinear hollow body accommodating a bidirectional shock absorber and interacting selectively with a first or a second magnetized stroke limiting pivot which are associated with a first guide or with a second guide,
wherein the rectilinear hollow body has an upper profile that is shaped, in a side view, substantially like an upturned V so as to define two inclined planes, at a vertex there being a first seat within which a shaft that protrudes transversely with respect to the entrainer can be coupled with a snap action.

A damping or return device for sliding door leaves, particularly for furniture, comprising:

a rectilinear hollow body made of plastic material, which is slideably associated with a profile that is integral with a top of a piece of furniture and can be coupled automatically and with a snap action to an entrainer that is fixed to one of the door leaves by way of a carriage;
a bidirectional shock absorber accomodated by the rectilinear hollow body and interacting selectively with a first or a second magnetized stroke limiting pivot which are associated with a first guide or with a second guide, wherein the bidirectional shock absorber has a pair of hollow deceleration cylinders that are connected axially by a pivot which is partially and slideably associated therein and has a disk interposed at a centerline, between a facing end of the deceleration cylinders, and the bidirectional shock absorber having a cylindrical helical compression spring, the dimensions of the bidirectional shock absorber being such that, at rest, the deceleration cylinders protrude slightly beyond the ends of the rectilinear hollow body.

A damping or return device for sliding door leaves, particularly for furniture, comprising:

a rectilinear hollow body made of plastic material, which is slideably associated with a profile that is integral with a top of a piece of furniture and can be coupled automatically and with a snap action to an entrainer that is fixed to one of inner and outer door leaves by way of a carriage, the rectilinear hollow body accommodating a bidirectional shock absorber and interacting selectively with a first or a second magnetized stroke limiting pivot which are associated with a first guide or with a second guide,
wherein the piece of furniture is constituted by two sides, a top and inner and outer door leaves, which lie on mutually parallel planes and mutually overlap, a first guide for the outer door leaf on the top and a second guide, which is parallel to the first guide and is arranged proximate to a front perimetric edge of the top, for the inner door leaf, the device being associated with each one of the door leaves, the profile being arranged in a region that is intermediate between the first and second guides or the profile being arranged in a region that is adjacent to the first guide in a direction that is opposite with respect to the front perimetric edge,
wherein the first magnetized pivot and the second magnetized pivot are associated with the profile that is arranged in the region that is intermediate between the first and second guides, the first magnetized pivot and the second magnetized pivot being associated with the profile that is arranged in the region that is adjacent to the first guide in the direction that is opposite with respect to the front perimetric edge,
wherein each one of the first and second magnetized pivots is constituted by a cylindrical magnet that is arranged axially with respect to a sleeve that protrudes from a footing that can be associated with the profiles, the sleeves being arrangeable selectively and slideably within the rectilinear hollow body.
