Definitions

  • the present invention concerns the production of components for household electric appliances and the like.
  • appliance doors such as ovens, dishwashers and the like, are fixed to the frame structure of the household electric appliance by means of hinge devices allowing the door rotation between a closed and opened position.
  • the rotation center doesn't coincide with the bottom of the door frontal panel, which therefore must be kept rised from the baseboard top, allowing the free rotation of the door.
  • This mutual spaced misplacement of the door frontal panel from the baseboard top doesn't allow to cover in optimal way the empty space between the appliance bottom and the floor, therefore the baseboard function is partially reduced.
  • the object of the present invention is to realize a hinge device allowing a door misplacement with respect to the baseboard without hindering the door opening and closing.
  • a further object of the invention is to realize said hinge device maintaining a structure having great constructive and functional simplicity, as well as economic structure under the productive profile.
  • the hinge device of the present invention is used particularly with a door 28 to be assembled on household appliances and the like.
  • two hinge devices of the here described type are used for assembling a door, which are applied, for instance, in correspondence of the two lower angles of the opening to be closed by the door.
  • number 1 indicates a coupling element of the hinge device, constituted by a plate suitably shaped fixed to the appliance structure 10, for instance by means of screws 30, shown in figure 2.
  • the coupling element 1 supports, pivoted at a fulcrum 24, an elongated pivoted element 4 that is a rocker arm element pivotable on a vertical plane parallel to the coupling element 1.
  • the end of the rocker arm element 4 disposed toward the door 28 has a transversal pivot 3 with the orizzontal axle perpendicular to the rocker arm element with a support element 2, fixed to the door 28, linked thereto.
  • the support element 2 is made, in a known way, with a sheet metal element fixed longitudinally to the door 28.
  • Moving means acting on the rocker arm element 4, depending on the opening angle of said door 28, are provided to cause the roker arm element pivoting.
  • Said moving means include a series of elements described as followiong in an illustrative and not limitative embodiment, and the inventive concept is based on having disposed the door rotation center on a pivoting element.
  • the oscillating plate 6 is above the rocker arm element 4, and has some protrusions in correspondence thereto hinge connections 20, 21, 22, are carried out, well shown in figure 4. Obviously it is possible to carry out the plate without protrusions, providing that the mutual misplacing of the hinge connections is guaranteed.
  • a second hinge connection 21 is connected to the end of the rocker arm element 4, opposite to the door 28, by means of an elongated connection element 9.
  • the connection element 9 is hinged to the rocker arm element 4 in correspondence of a fulcrum 29 (figure 3).
  • connection point 22 of the pivoting plate 6, opposite to the connection point 21 joined to the rocker arm element 4 by means of the connection element 9, is connected to the door 28 by means of a shaped segment 5 that is hinged to a pivot 7 just above the pivot 3, on the support element 2 fixed to the door 28.
  • Said couterbalancing means 8,11 oppose the door 28 weigth, according to known techniques, particularly with a variable elastic reaction depening on the door opening.
  • the door stress on the counterbalancing means varies depending on the door opening degree.
  • the counterbalancing means include a L-shaped lever 11 with an end hinged to the coupling element 1 and the other one fastened to an elastic element 8 that is a spring subjected to a tensile stress.
  • the spring 8 is vertically displaced above the plate 6 and exertes an upwardly traction at the end of L-lever 11 fastened thereto.
  • the effect is to give a rotation stress to the plate 6 determining a traction, transmitted by the shaped segment 5, to the door 28 in opposition to its opening, therefore getting a counterbalancing effect.
  • the variability of the couterbalancing effect is obtained bu suitably shaping the inner part of the L-lever.
  • the surface run by the roll 13 has a wedge shape 25, so that in the first portion, between the angle of the L-lever and the top of the wedge 25, the traction on the door is greater than in the portion over the wedge top.
  • stop members 12, 15; 14, 16 designed to determine the stop position during the opening of the door 28.
  • Such stop members are made by providing complementary and opposite surfaces 12, 15 on the support element 2 and on the shaped segment 5, designed to mutually engage to define the maximum door opening position (figure 4), in cooperation with two complementary and opposite surfaces 14, 16 of the rocker arm element 4 and of the pivoting plate 6 mutually engaging.
  • the door bottom can pass above the baseboard 31, as well shown in figure 3.
  • the pivot 3 In the second opening portion, namely from 45-50 degrees on, the pivot 3 returns to go down and to move inward, but this doesn't cause any problem, since the door bottom has already passed the baseboard top 31.
  • the roll 13 act in traction on the spring 8 during this movement.
  • the components particularly the shaped segment 5, may have some notches and some seats 51, 52 (suitably indicated in figure 4) designed to house parts or ends of the other components, in their extreme positions (see figure 1).
