Definitions

  • This invention relates to an actuation device with variable balancing for sliding doors of furniture and the like, especially of the type having shelves.
  • Said device must be of small bulk and weight, capable of being housed in correspondence with the lateral wall of the furniture, a wall which in any case must be present as it constitutes the load-bearing structure of same, and which shall be easy to install and maintain and of low cost.
  • an actuation device which provides means for balancing variable forces, especially for sliding doors of furniture, comprising supporting and guiding means for the sliding door, capable of engaging with movable suspension means adapted for enabling said door to be moved in translatory motion, said movable suspension means being firmly attached to elastic means adapted for imparting to said suspension means a variable reaction force, which in every possible position and at every instant balances the forces acting on them.
  • said supporting and guiding means for the sliding door are constituted, for each side of the door, of a vertical carriage integral with the edge of said door, slidable on the side of the furniture item along lateral guides perpendicular to one another and fitted to the side of the furniture, and having a horizontal arm orientated towards the back wall, said arm bearing upon a wheel attached to a suspension link, onto which the weight of the door is transferred, said suspension link being, in turn, articulated to the free end of a rod pivotally mounted on the side wall of the furniture item, said free end being also connected to elastic reaction means for the automatic and instantaneous balancing of the weight of the door in whatever position it is situated.
  • said link with its associated wheel, on which each edge of the door rests in slidable manner always remains in a vertical position, transferring the weight of the door in a constant manner in regard to both value and direction.
  • said elastic reaction means shall be preferably constituted of a spring or the like, having one end fixed in adjustable manner to the wall of the furniture item and the other end to the free end of said rod, it being possible for said spring to be arranged with a variable line of action depending upon the position of the point of attachment to said rod, which in turn can be varied with the position of the door.
  • the actuation device with variable balancing 1 is composed a rod 2 having one end 2a pivotally mounted in a predetermined position fixed to the side wall 100a of the furniture item 100, the other end 2b of said rod being free and having, articulated to it, a link 3, the free end of which supports a wheel 4, engaged to run on a horizontal arm 5 of a carriage 6 with vertical direction of travel, to which is attached one edge of the vertically slidable door 7.
  • the suspension carriage 6 for the door 7 is guided on its vertical travel by two pairs of wheels 8a, 9a and 8b, 9b, disposed at 90° to one another and mounted on the carriage 6, which run in two guides 10 and 11 of a profile member 10a fixed to the side of the furniture item, thus assuring perfect linearity of the displacement and the absence of skidding during said travel.
  • the couple to be balanced is given by the product of the constant weight P times the arm D j .
  • the balancing action of the spring 12, acting along the line of action 12c varies with the position of the end 2b of the rod 2 and will increase linearly with the extension of the spring during the travel of the rod 2, while the lever arm "d i " will decrease with the same movement of the rod 2.
  • FIG 4 there is shown a variant of the device according to this invention, which can be used in the case of a double door 7′; in this case, the carriage 6 is attached to the door 7′ in an intermediate position and bears on a wheel 4′, attached to one end of a cable 15, fixed at its other end to the side of the item of furniture and passing over a pulley 16, connected to the lever 2 in the form of a simple tackle.
  • said elastic reaction means may be realized by means of equivalent elements, such as air springs, fluid springs, rubber springs or the like, of known type adapted for providing an action which varies with the extension and a line of action which also is variable, but in the opposite sense for the purpose of achieving at every instant and in every position the balancing of the couples acting on the rod 2.
