Definitions

  • the present invention relates to a hinge for the doors of electric household appliances, furniture and the like, having separate resilient elements which are attached to the door and to the electric appliance and which exert a combined action for balancing of the door during the opening/closing rotational movement thereof, and also comprising a device for stopping rotation of a lever connected to said balancing means attached to the electric appliance, which can be deactivated upon each rotation of the door in either direction and activated when the door itself is extracted from its seat.
  • hinges for said electric appliances such as ovens and the like, consisting of a part attached to the door, with which they are articulated in a mutually connectable manner in a predetermined position so as to allow rapid and precise extraction/reinsertion of the oven door by means of releasing of the said arms from the fixed hinge part attached to the electric appliance.
  • the movable part of said hinges, attached to the door contains a balancing spring designed to keep the door as balanced as possible during the rotational opening and closing movement, by exerting, in the first case, a braking action and, in the second case, a recall action, which reduce the amount of force required by a user in order to perform these two manoeuvres.
  • the technical problem which is posed is therefore that of providing a hinge for the doors of electric household appliances such as ovens and the like, which enables doors of considerable weight to be operated without the need for over-dimensioning of the parts which make up the hinge itself and without requiring a considerable amount of force on the part of the user.
  • the hinge should be of the type with arms which can be connected to each other for rapid extraction of the door; moreover, it is required that the hinge according to the invention should be easy and economical to produce with a small number of parts which are not subject to particular wear and that it should be able to be dimensioned such that it can be applied to the conventional doors of electric household appliances and the like, without the need for variations in the dimensions and existing connections.
  • a hinge for the doors of electric household appliances, furniture and the like comprising a plate which is fixed to the wall of the electric appliance and which has connected to it a first box-shaped element forming the fixed guiding part of the hinge, a second box-shaped element connected to the door and carrying a fixed arm and a movable arm which can be connected to each other via associated engaging means, and resilient means for balancing the door, in which said fixed plate has hinged to it a rod which is subject to the recall action of resilient means and the free end of which has means designed to engage/disengage with/from the free end of said movable arm during the rotational opening/closing movement of the door, there also being provided a device for stopping the return movement of the rod into the rest position, which can be deactivated via the free end of the arm upon each rotation of the door in either direction and activated when the two said hinge arms are engaged with one another for extraction of the door itself.
  • the hinge 1 is composed of a plate 1 connected, via screws 1a or the like, to the fixed wall 100 of an electric household appliance or the like.
  • the plate 1 In addition to forming the fixed support of the hinge, the plate 1 also forms a protective barrier for the insulation material present in some electric appliances such as ovens for example, which is worn by the abrasive action of the movable parts of the hinge during the opening/closing rotational movements.
  • the edge 1b of the plate 1 corresponding to the front opening of the furniture and/or electric appliance has fixed to it a box-shaped element 2 carrying a roller 2a and a pin 2b which are transverse with respect to the direction of opening of the hinge, as will become clear below.
  • the part of the hinge 1 movable in rotation is formed by a second box-shaped element 3 which is located inside the thickness of a door 4 for closing the compartment of the electric appliance.
  • Said box-shaped element 3 located inside the door 4 has a first transverse pin 3a and a second transverse pin 3b;
  • the pin 3a has hinged on it a first arm 5 movable with the door 4 and guided by the said roller 2a attached to the fixed box-shaped element 2;
  • the pin 3b has hinged on it a second right-angled arm 6 which is engaged with the fixed box-shaped part 2 by means of a seat 6a and is kept immobile on the fixed part 3 itself by means of said pin 2b.
  • the pin 3b of the said fixed arm 6 therefore forms the fixed axis of rotation of the hinge 1.
  • the box-shaped element 3 also has housed inside it a rod 14a, the opposite ends of which are retained by pins 14b and 14c which are attached respectively to the box-shaped element itself and the end 5a of the arm 5; said rod 14a has mounted on it a helical spring 14 which, being compressed or extended during opening/closing of the door 4, performs the required action of balancing/recalling of the door itself.
  • the plate 1 attached to the electric appliance also has hinged on it a rod 7 kept in abutment against a stop 7a by the recall action of a spring 8 arranged between a fixed projection 8a of the plate 1 and a pin 7b attached to the rod 7.
  • the free end of the rod 7 has a transversely projecting pin 7c designed to engage with a corresponding hook 5c formed in the free end 5b of the movable lever 5 which also has a second hook 5d in an approximately intermediate position of its bottom profile.
  • Said second hook 5d is designed to retain a bridge-piece 10 hinged on the upper surface of the fixed arm 6 so as to form a connection between the two arms 5 and 6 which, as will be described more fully below, allows extraction/insertion of the hinge and hence the door from/into the fixed seat 2.
  • the plate 1 has mounted on it a pawl 9 rotating about a pin 9a and pushed into abutment against a stop 9b by the action of resilient means 11 attached to the plate 1.
  • the free end of the pawl 9 has, thicknesswise, a portion 12 folded so as to form an inclined surface 12a, a bottom rounded vertex 12b and a front abutment surface 12c designed to cooperate with the rear surface of the free end of the rod 7.
  • the hinge operates in the following manner:
  • the hinge operates as follows: after reaching the angular position which allows engagement of the bridge-piece 10 with the intermediate hook 5d of the arm 5, the door 4 can be rotated upwards, freeing at the same time the fixed arm 6 from its seat and the hook 5c of the movable arm from the pin 7c of the rod 7 which, recalled by the action of the spring 8, returns back until its free end comes into abutment against the end surface 11c of the pawl 9 which, no longer interacting with the lever 5, has lowered, creating the desired obstacle which keeps the rod 7 in a predetermined position.
  • the support plate 1 may also be provided with safety microswitches 300 designed to cooperate with the movable arm 5 in order to activate/deactivate for example the oven resistances and/or other auxiliary devices for closing/opening of the door 4 itself.
