Definitions

  • the present invention relates to a hinge for doors of kitchen ovens.
  • Hinges for oven doors or doors of other similar apparatuses are generally constituted by a first arm, to be associated with the door for closing the chamber of the oven, and by a second arm, to be associated with the structure of the oven, and articulated to the first arm.
  • a kinematic mechanism designed to interact with elastic means for the facilitated closing and opening of the door, while at the same time ensuring the rotation of the second arm with respect to the first arm with a controlled movement, thus ensuring positions of stable equilibrium for the door, both in the configuration of being closed on the chamber of the oven and in the configuration of being open, as well as in any intermediate positions.
  • hinges for kitchen ovens which are provided with systems for slowing the closing stroke of the door, which are designed to prevent the sudden impact of the door against the body of the oven caused by the action of the elastic means for the facilitated closing of the door against the body of the oven.
  • Such systems for slowing the closing stroke of the door are however not capable of preventing the bump of the tilting door against the structure of the oven and they cause a rebound of the door, with closing in two stages, when it is slammed by forceful closing pushes or if it is applied to doors that have considerable masses.
  • a hinge for ovens is disclosed in WO2015/086470 .
  • the aim of the present invention is to provide a hinge for doors of kitchen ovens that is capable of overcoming the above mentioned drawbacks.
  • an object of the invention is to provide a hinge for doors of kitchen ovens that is capable of preventing the closing bump between a tilting door and the structure of the oven and the subsequent rebound with an antibounce system.
  • Another object of the invention is to provide a hinge that is capable of slowing the closing of the door in the event of immediate release of the door, even for opening angles comprised between 0° and 10°.
  • Another object of the invention is to provide a hinge that is structurally simple and easy and cheap to assemble.
  • Another object of the invention is to provide a hinge that is easy to disassemble by virtue of a system that is agile and pleasant to look at.
  • Another object of the invention is to provide a hinge that can be easily installed even on existing ovens.
  • a hinge for doors of kitchen ovens in a first embodiment, is generally designated with the reference numeral 10.
  • Such hinge 10 is of the type comprising a first arm 11 to be associated with a door for closing a chamber of an oven, and a second arm 12, articulated to the first arm 11, to be associated with the structure of the oven 53.
  • a kinematic mechanism 13 Interposed between the first arm 11 and the second arm 12 is a kinematic mechanism 13 which is adapted to actuate elastic means 14 for the facilitated closing of the door, between the first arm 11 and the second arm 12 there also being interposed means 15 for slowing the closing movement of the door.
  • a peculiarity of the invention consists in that the means 15 for slowing the closing movement of the door comprise a container of a fluid-operated damper 16 which is affixed to a containment body 17, which is part of the first arm 11.
  • the fluid-operated damper 18 contained in the container 16 is actuated by a first contoured end 19 of a transmission element 20, which can be shifted with respect to the containment body 17.
  • the second contoured end 21 of the transmission element 20 is designed to slide in contact with a pusher portion 22, with a predefined and fixed angle of inclination, of an integrated element 51, which is in turn connected to the second arm 12.
  • Such pusher portion 22 is adapted to correspond to the portion 52 of the second arm 12.
  • the transmission element 20 and the pusher portion 22 are arranged on the respective first arm 11 and second arm 12 so that the second contoured end 21 of the transmission element 20 and the pusher portion 22 meet for a preset angle for slowing between the door and the facade of the oven.
  • the antibounce system 58 is made up of:
  • the containment body 17 of the first arm 11 is provided by a profile which is predominantly longitudinally extended and is substantially U-shaped in cross-section, with openings, holes and folds designed for the mounting of the kinematic mechanism 13, of the elastic means 14, and of the means for slowing 15; these should be understood as being of known type.
  • the second arm 12 is constituted by:
  • the kinematic mechanism 13 comprises the second portion 26 of the second arm 12, which is pivoted as mentioned to the containment body 17, the mentioned first element 28, which is composed of two opposing contoured plates 30 which are joined by a rear joining bridge 31 and are hinged to the second portion 26 with the second rivet 29 and to a second element 32 of the kinematic mechanism 13 with a third rivet 33.
  • the second element 32 is also defined between two opposing contoured plates 34 which are joined by a bridge 35, and a fourth rivet 36 for coupling the elastic means 14 is fixed between such contoured plates 34.
  • the elastic means 14 takes the form, for example, of a helical traction spring 37 interposed between the fourth rivet 36, lower, and a fifth rivet 38, upper, which is fixed transversely to the side walls 39 and 40 of the containment body 17.
  • the second element 32 also carries a roller 41 for sliding on a cam-like curved edge 42 defined on the second part 26 of the second arm 12.
  • the container of the fluid-operated damper 16 is fixed to the containment body 17 by simple interlocking, it being arranged with a rear lower portion thereof 43 on two corresponding resting flaps 44 which are defined on the side walls 39 and 40 of the containment body 17, and locked in an upper region by an extraction-preventing abutment tab 45 which is provided centrally on the central wall of the containment body 17 and/or by a lateral stud 46.
  • the container of the fluid-operated damper 16 is therefore locked without the use of rivets or other locking elements, but only by way of conveniently contoured portions of the containment body 17 itself.
  • the transmission element 20 is constituted by a flat bar which is arranged so as to slide between two pairs of symmetrical guide tabs, a first pair of lower tabs 47 and a second pair of upper tabs 48, both of which are defined on the side walls 39 and 40 of the containment body 17.
  • the second contoured end 21 of the transmission element 20 is inclined with respect to the arrangement of the flat central part, so as to protrude from the space occupation of the containment body 17, available for contact with the pusher portion 22.
  • the pusher portion 22 is constituted by a plate-shaped appendage.
  • the integrated element 51 is fixed to the second arm 12 by way of the rivet 50.
  • the second contoured end 21 of the transmission element 20 encounters the plate that defines the pusher portion 22 at an angle for slowing 24 between the door and the facade of the oven which is comprised between 40° and 0° and is preferably 10°.
  • FIG 1 shows the hinge 10 according to the invention in the configuration in which the door 52 is closed on the body of the oven 53.
  • the antibounce system 58 prevents its "rebound effect", keeping the arm 12 and the body of the oven 53 mutually integral.
  • Figures 4 to 8 show a hinge for doors of kitchen ovens according to the invention in a second embodiment and is designated with the reference numeral 110.
  • Such hinge 110 is of the type comprising a first arm 111 to be associated with a door for closing the chamber of an oven, not shown in the figures, and a second arm 112, articulated to the first arm 111, to be associated with the structure 153 of the oven.
  • a kinematic mechanism 113 Interposed between the first arm 111 and the second arm 112 is a kinematic mechanism 113 which is adapted to actuate elastic means 114 for the facilitated closing of the door.
  • first arm 111 and such second arm 112 there are also interposed means 115 for slowing the closing movement of the door.
  • a peculiarity of the invention consists in that the means 115 for slowing the closing movement of the door comprise a container 116 of a fluid-operated damper 118 which is affixed to a containment body 117, which is part of the first arm 111, and the damper 118 contained therein.
  • the fluid-operated damper 118 contained in the container 116 is actuated by a transmission element 120, which is in a single piece with the body 116 for containing the damper, and can translate with respect to the containment body 117 of the first arm 111.
  • the transmission element 120 has a contoured end 121 which is designed to slide in contact with a pusher portion 122, with a predefined and fixed angle of inclination, of an integrated element 151, which is in turn connected to the second arm 112.
  • the integrated element 151 is made of plastic material.
  • the pusher portion 122 is integral with the integrated element 151 with a preferred angle of inclination with respect to a vertical in the configuration for use.
  • This pusher portion 122 is adapted to correspond to the portion 152 of the second arm 112.
  • the transmission element 120 and the pusher portion 122 are arranged on the respective first arm 111 and second arm 112 so that the contoured end 121 of the transmission element 120 and the pusher portion 122 meet for a preset angle for slowing between the door and the facade of the oven.
  • One of the peculiarities of the invention consists of the method of associating the second arm 112 with the structure 153 of the oven.
  • the second arm 112 has an arc-shaped appendage 160.
  • the integrated element 151 has two mutually opposite and coaxial holes 161, oval in profile, each one on a corresponding side wall 162 of the element 151.
  • Such holes 161 are adapted for the insertion of a translating pin 163.
  • This pin 163 has two widened ends which allow them sufficient play to translate within the holes 161, without exiting completely therefrom.
  • the pin 163 can slide by virtue of the profile of the holes 161.
  • the appendage 160 of the second arm 112 is adapted for the insertion of the pin 163, in order to generate an interference and clamp the second arm 112 to the structure 153 of the oven.
  • the integrated element 151 is fixed to the second arm 112 by way of the rivet 150.
  • the second arm 112 has an end 165, substantially parallel to the appendage 160, which is adapted to be inserted in a corresponding hole 166 of the structure 153 of the oven.
  • the second arm 112 also has a recess 164, on the opposite edge to that from which the integrated element 151 extends, which is adapted to generate an interference with the structure 153 of the oven.
  • the door can be installed on and/or removed from the oven very quickly and without the need for tools.
  • the hinge 110 comprises an antibounce system 158 which is made up of:
  • the containment body 117 of the first arm 111 is provided by a profile which is predominantly longitudinally extended and is substantially U-shaped in cross-section, with openings, holes and folds designed for the mounting of the kinematic mechanism 113, of the elastic means 114, and of the means for slowing 115; these should be understood as being of known type.
  • the second arm 112 comprises:

  • the elastic means 114 are constituted, for example, by a helical traction spring 137 interposed between the fourth rivet 136, lower, and a fifth rivet 138, upper, which is fixed transversely to the side walls 139 and 140 of the containment body 117.
  • the second element 132 also carries a roller 141 for sliding on a cam-like curved edge 142 defined on the second part 126 of the second arm 112.
  • the container 116 of the fluid-operated damper 118 is fixed to the containment body 117 by simple interlocking, it being inserted with a rear portion thereof 143 in contact with two corresponding resting flaps 144 which are defined on the side walls 139 and 140 of the containment body 117, and locked in an upper region by an extraction-preventing abutment rivet 169, in contact with the damper 118.
  • extraction-preventing rivet 169 passes through two corresponding through holes 170 each of which is provided on one of the side walls 139 and 140 of the containment body 117.

  • the antibounce system 158 prevents its "rebound effect", keeping the arm 112 and the body of the oven 153 mutually integral.
  • a hinge has been provided which, by virtue of the peculiar means for slowing the closing movement of the door, makes it possible for the door to approach the body of the oven without the "rebound effect" and without any audible sound being emitted, differently to what occurs with conventional hinges, in which the closing movement concludes with a clearly audible impact.
  • a hinge has been provided that is structurally simple and easy and cheap to assemble, by virtue of the limited number of components and mounting elements, which are almost exclusively rivets; in particular the fluid-operated damper is associated with the containment body of the first arm without using rivets or other affixing elements.
  • the positioning in the door makes the hinge according to the invention simpler to disassemble if needed than conventional hinges mounted in the body of the oven.
  • the hinge according to the invention can be easily installed even on existing ovens.
