Definitions

  • the present invention concerns the technical field for the production of components for household electric appliances and the like.
  • the cited hinge devices must fulfil an appropriate weight balancing of the door, so as to prevent the sudden rotation downward of this latter during the opening operation.
  • a known hinge device includes a coupling member constituted by a suitably shaped plaque, fixed to the structure of the household electric appliance and having pivoted, on a transversal pivot, a support member fixed to the door.
  • Such support is carried out by using a plate section along which an elastic clamping member, having a transversal roll, is assembled slidingly and opposed by suitable spring members; such roll is fit to engage, at the closing position, an housing shaped on the cited coupling member.
  • the opening position of the door is defined by a pivot assembled transversely to the cited support member and designed to meet, at the aforesaid opening position, an housing made on the coupling member.
  • a complained problem of the cited hinge devices is due to the stresses weighing thereon in correspondence of the opening position of the door.
  • the hinge devices could also support an additional load, for instance depending on the objects supported by the open door, if necessary, besides the door weight. In other words, it is necessary to prevent that, in consequence of stresses greater than the expectation, a deformation of the same hinge devices will occur, so as to cause a defective closing of the door.
  • the object of the present invention consists of making an hinge device designed to support high stresses without undergoing deformations during the opening operation, also maintaining a structure having an enormous constructive and functional simplicity and a wide productive cheapness.
  • reference numeral 1 indicates a coupling member of the hinge device, constituted by a suitably shaped plaque, fixed to the structure 10 of the household electric appliance.
  • the coupling member 1 is pivoted, on a transversal pivot 3, to a support member 2 fixed to the door of the household electric appliance, not shown. More precisely, the coupling member 1 substantially lies on a longitudinal median plane of the support member and is inserted with its protruding portion la inside the support member 2, through an opening 4 carried out frontally to this latter.
  • the support member 2 is carried out, in a known way, from a plate section along which the body 7 of an elastic clamping member 8 is assembled slidingly and is opposed by suitable spring members 5 and 6.
  • This body 7 is made in turn from a plate section, suitably folded up so as to define two faced sides 17; such sides 17 are adjacent to corresponding sides of the support 2, at the assemblage position.
  • the elastic clamping member 8 has a transversal roll 9 that is fit to engage, at the closing position, an housing 11 shaped on the cited coupling member 1, along the upper edge.
  • the opening position of the door is defined by a pivot 12 transversely assembled as regards to the support member 2, in correspondence to the cited opening 4, and it is fit to meet, at the aforesaid opening position, a slot 13 carried out on the protruding portion la of the coupling member 1.
  • the hinge device In correspondence of the hinging zone of the support 2 with the coupling member 1, the hinge device has a stiffening member 14 fit to meet the same coupling member 1, at the aforesaid opening position.
  • the stiffening member 14 is made from the body 7 that support the elastic clamping member 8.
  • the stiffening member 14 is constituted by at least a wing 15 shaped at the end of one of the sides 17 of the aforesaid body 7, on a plane parallel to that of the same side 17; the wing 15 is partially protruding from the opening 4 of the support 2, in correspondence of the assemblage position.
  • the wing 15 shapes a hollow 16 fit to engage a pin 18 protruding transversely from the coupling member 1, at the opening position of the aforesaid door.
  • the second side 17 of the body 7 has, at its end, an analogous wing, for clarity represented with the outlined line 15a in Figure 3.
  • the pin 18 is protruding bilaterally from the coupling member 1, so as to be engaged simultaneously by the hollow 16 of the cited wings 15, 15a.
  • the wings 15, 15a extend from respective tabs 19, achieved by refolding the sides 17 of the body 7, and lie on planes parallel to the same sides 17, at a mutual distance smaller than these latter. In this way the wings 15, 15a are lain substantially behind with the opposite lateral faces of the coupling member 1.
  • the stiffening member 14 is able of carrying out a distribution of the stresses weighting heavily on the hinge device at the opening position of the door, shown in Figure 2.
  • the load acting on the support 2 of the hinge device is really transferred, by virtue of the engagement of the coupling member 1 with the pin 18, on the hollow 16 of the wings 15, 15a, and also acts directly on the pivot 12 meeting the slot 13 of the coupling member 1.
  • the member 14 is therefore a considerable stiffening of the support 2 in correspondence of the hinging zone with the coupling member 1, mostly subject to the stresses.
  • the described hinge device reaches therefore the object of withstanding without buckling under high stresses, during the opening operation of the door.
  • the stiffening member 14 comprises a peg 20 transversely fixed to a pair of wings 21 that constitute practically the extension of the said tabs 19 of the sides 17 of the body 7.
  • the peg 20 is fit to engage, at the opening position of the aforesaid door, a hollow 22 carried out on the protruding portion la of the coupling member 1. Simultaneously the aforesaid wings 21 are pushed through a slot 23 carried out on the bottom of the support member 2, adjacent to the opening 4, till the beat of the tabs 19 against the same bottom of the support member 2. This enable the increment of the general resistance in sensitive manner.
