Definitions

  • the present invention concerns an adjustable counterbalancing system, specially suitable for hinges with horizontal axis, used as articulation of the door and body of a household electric appliance.
  • the present system is fitted for all auto-balancing hinges that counterbalance during opening and closing operations of the door.
  • the system is equipped with a mechanism that moves in relation with the hinge movement, connected with an elastic extendible member, stressed so that its elastic reaction varies in accordance with the door position and balances the torque produced by the door weight.
  • the object of the present invention is a counterbalancing system of the above described type, applied to a particular hinge, such as the one disclosed in the Italian Patent No. 1.235.584 of the same Applicant.
  • This hinge shown in a prospective view in Fig. 1, is substantially constituted by a first member 1, aimed at being fastened to the frame structure of the electric household appliance A, and a second member 2, aimed at being fastened to the door P of the electric household appliance, pivotally connected to the first member 1 in 3.
  • the hinge is provided with a mechanism constituted by cooperating members 4, 5, 6, located between the first and the second members, as described in the above mentioned Italian Patent.
  • the member 6 is connected with a counterbalancing system that has an extendible member 7 formed by a first spring end connecting member 8, a helical spring 9, that is subjected to tensile stress, and a second spring end connecting member 10, fixedly fastened, by means of a square plate 11, to the frame structure A of the electric household appliance.
  • the free end of the member 6, connected to the first spring end connecting member 8, moves away from the square plate 11, and the extendible element 7 extends, gradually increasing the reaction force caused by the spring 9, that is subjected to the tensile stress, and thus counterbalances the torque produced by the door weight.
  • the torque increases in accordance with the lever arm increase that depends on the door opening angle.
  • the main object of the present invention is to propose a counterbalancing system that resolves the above reported problems by making use of a spring that is subjected to compressive stress, and means for adjusting the counterbalancing force.
  • the adjustable counterbalancing system that is the subject of the present invention, is applied to a particular kind of hinge, described in the introductory part, such as the one disclosed in the Italian Patent No. 1.235.584, but it is obvious that this type of hinge has been used as a mere example, therefore the same system can be applied also to other types of hinge, performing the same function within the same inventive idea.
  • the hinge includes a first member 101, fastened to the frame structure of the electric household appliance and a second member 102, fastened to the appliance door.
  • the two members 101 and 102 are pivotally connected to each other in 103.
  • the member 101 has a transversal "C"-like part that defines three walls 101a, 101b, 101c (see fig. 2B).
  • the system is equipped with a mechanism that includes cooperating members 104, 105, 106, located between the first member 101 and the second member 102.
  • the free end of the member 106 that protrudes from the mechanism, moves in accordance with the hinge opening-closing movement.
  • a link member 21 With reference to fig.2, the lower end of a link member 21 is carried, pivoted in 20, by the member 106, while the other end of the link member 21 is engaged with an end of an extendible member 22.
  • the extendible member 22 includes two "T"-like flat bars 22a, 22b, situated side by side and longitudinally opposite to each other, and by a helical spring 23, set around the flanked stems of the "T"-like bars, so as to be compressed between the two opposite heads of the "T"-like bars.
  • the end, opposite to the head, of the bar 22a, is fastened to the link member 21, while the corresponding end of the other flat bar 22b, opposite to the above mentioned head of the flat bar 22a, is connected with the free end of a cable 24.
  • the cable 24 extends upwards and then is sent downwards turning around a roller 25 that is rotatably supported by the member 101.
  • the other end of the cable 24 is fixed in a point 26 by a clamp 27 constituting a part of a guide-support plate member 28 (fig. 3A).
  • the guide-support plate member 28 includes a plate, fixed to the member 101 by nails or rivets 29, and featuring a slot 30 that acts as a horizontal guide for a cylindrical small barrel 31.
  • a pin 33 acting as a stationary stop, is also fastened to the plate member 28.
  • the barrel 31, as seen in fig. 3A, has a first groove 31a that engages the cable 24, a second groove 31b, and a threaded hole 31c.
  • the second groove 31b engages slidingly with the slot 30 so as to obtain a guided sliding connection between the barrel 31 and the guide-support plate member 28.
  • the threaded hole 31c engages a screw 32, the head 32a of which rests turningly against the wall 101a of the member 101, so that it is possible to act on the head 32a of the screw by a key 34 from outside of the wall 101a.
  • the above described counterbalancing system exploits the elastic reaction of the helical spring 23, that is pre-loaded according to a predetermined value, when the door is closed, and, during opening of the door, the spring is gradually compressed between the wider heads of the two flat bars 22a, 22b.
  • the free end of the cable 24 is fixed directly to a link member 121, functionally similar to the analogous member 21, and the extendible member 22 is subjected, by interpositions of a roller 125, to the stresses transmitted thereto by the cable 24 during the door opening.
  • the end of the flat bar 22b of the extendible member 22, opposite to the head is shaped in such a way that it can hook in a seat 101d made in the member 101 (fig.7), while the respective end of the other bar 22b features a fork 122, that bears rotatably the roller 125, sending back downwards the cable 24.
  • the barrel 31 movement causes releasing or tensioning of the cable 24, that, correspondingly reduces or increases the compression of the pre-loaded spring 23, that results in reduction or increase of the counterbalancing action.
  • the spring 23 can be used to define the maximum hinge opening by adjusting the barrel 31 using the screw 32 until the turns of the spring 23 are packed when the hinge is opened at most.
