Definitions

  • the invention relates to a lifting system for furniture piece doors oscillating around a horizontal axis, in particular for lifting doors of hood units.
  • each of these systems comprises one or more support levers connected in an articulated manner between the body of the furniture piece and the door to be lifted, as well as comprising an elastic device, for example a gas spring, operatively connected to the lever so as to exert the necessary force for lifting the door.
  • an elastic device for example a gas spring
  • the operative connection between the lever and the elastic device can be indirectly achieved through an oscillating intermediate member, to which the elastic device is connected, which member has a roller that acts upon a cam of the support lever so as to transmit the force of the elastic device to the lever itself.
  • the operative connection between the lever and the elastic device can be directly achieved by providing an articulation pin on the support lever to connect the rod of the piston of the elastic device itself, the pin being disposed at a distance from the oscillation axis of the support lever, a solution that is preferable because of its greater constructive simplicity.
  • the gas spring delivers a force that varies in a limited manner during its extension, in such lifting systems, especially if the gas spring is directly connected to the lever, it may occur that the torque exerted by the spring during a first opening arc of the hood unit is preponderant relative to the torque opposed by the weight force of the door or doors, whereas in another opening arc, corresponding to the maximum extension of the hood unit toward the exterior of the furniture piece, in which the torque takes on the highest value due to the weight of the door, the torque of the spring is lower than it, so that the hood unit can neither be maintained in the desired position, nor pushed toward the maximum opening position.
  • the main object of the invention is thus to provide a lifting system capable of fulfilling the user's needs and of solving the above-mentioned problems.
  • one object of the invention is to realize a lifting system for furniture piece doors oscillating around a horizontal axis which provides precise control over the lifting of the door and enables the effectiveness of such control to be maintained unaltered over time.
  • the technical task, as well as these and other objects, according to the present invention are achieved by realizing a lifting system for a furniture piece door oscillating around a horizontal axis having a support lever of the door oscillating around an oscillation pin disposed on an inner side of a shoulder of the furniture piece and a first elastic device operatively connected to the support lever of the door to provide a moment in the closing direction of the door at the closed position of the door, and a primary moment in the opening direction of the door starting from a partial opening position of the door, characterized in that it comprises a second elastic device operatively connected to the shoulder and to the support lever so as to provide a force suitable for generating, relative to said oscillation pin, an auxiliary moment in the opening direction of the door and/or respectively an opposing moment via friction against the support lever in the direction opposite to the closing movement of the door along an arc of oscillation around the maximum extension of the door toward the furniture piece exterior.
  • the friction moment is suitable for opposing the movement of the hood unit, compensating for any differences between the moments generated by the first elastic device and the weight force so as to keep the hood unit in equilibrium.
  • the second elastic device is configured in a manner such as to provide, at said arc of oscillation of the door, an auxiliary moment in the opening direction of the door, which, summed with the primary moment in the opening direction of the door, substantially equals or prevails over the moment in the closing direction of the door due to the weight force of the door and the other parts integral therewith.
  • the second elastic device has means for adjusting its own force generating said auxiliary moment and/or said opposing moment.
  • said adjustment means are particularly advantageous for adapting the operation of the device to different weights of doors of different materials or thickness.
  • the second elastic device has a friction surface slidable along a cam provided on said support lever.
  • the second elastic device comprises a leaf spring having said friction surface.
  • said leaf spring has an angular configuration defining a first spring arm on which said friction surface is present and a second spring arm.
  • said adjustment means comprise an element for adjusting the pre- compression of said leaf spring.
  • said adjustment element comprises an eccentric operatively engaged with said second arm of said leaf spring.
  • the second elastic device comprises, as an alternative to or in combination with said adjustment element, elements which are abutted against zones of said cam with differentiated friction, made in particular of a different material.

  • the graph shows that at the closing angle (point of origin of the graph), the moment generated by the first elastic device is negative, i.e. it operates in the closing direction of the doors 3, 7.
  • the moment generated by the first elastic device becomes zero (the line of action of the piston 27 of the gas spring against the support lever 9 is radially directed at the oscillation pin 10 of the support lever 9), and upon exceeding the angle al it becomes positive, i.e. it operates in the opening direction of the doors 3, 7 (the line of action of the piston 27 of the gas spring against the support lever 9 passes from one side to the diametrically opposite side of the oscillation pin 10 of the support lever 9).
  • the second elastic device advantageously operates around the position of maximum extension of the door towards the furniture piece exterior, i.e. when the moment in the closing direction generated by the weight force takes on the maximum value.
  • the graph illustrates a section of overlapping between the curve of the moment in opening direction generated by the combination of the first elastic device and second elastic device with the eccentric 37 in the first adjustment position, and the curve of the moment in the closing direction generated by the weight force.
  • the doors 3, 7 exhibit a stable partially open position in the absence of the user's intervention.
  • figure 10 graphically shows the trend in the moments to which the double door 3, 7 of the hood unit of figure 1- 6 is subjected depending on the opening angle of the upper door 3, and with the varying of the performance of the first elastic device, it being well known, in particular, that gas springs can undergo a progressive decline in performance over time, particularly as a result of small gas leaks.
  • the trend in the moment in the opening direction of the doors 3, 7 generated by the combination of the first elastic device and second elastic device for opening angles larger than al, which is the angle at which the second elastic device is first triggered, is represented by the dash-dot line.
  • the graph shows that without the aid of the second elastic device, in the event of a loss of efficiency, the first elastic device could not achieve complete automatic opening of the doors 3, 7, given that, once the opening angle a4 was exceeded, the moment in the closing direction due to the weight force would prevail over the moment in the opening direction exerted by the first elastic device.
  • the second elastic device can be calibrated, according to preference, in a manner such as to cause a continuous movement of the doors 3, 7 toward the position of complete opening without the user's intervention (the curve of the moment in the opening direction generated by the combination of the first and second elastic device remains permanently above the curve of the moment in the closing direction generated by the weight force, as shown in the graph of figure 10) or a movement through stable partial opening positions (the curve of the moment in the opening direction generated by the combination of the first and second elastic device overlaps, in one section, the curve of the moment in the closing direction generated by the weight force, as shown in the graph of figure 9). It has been practically ascertained that the lifting system for a furniture piece door according to the invention is suitable for ensuring complete control over the opening of the door.
