Definitions

  • the present invention relates to a hinge for connecting the door of a home appliance to the body of the home appliance, according to the preamble of claim 1.
  • the transmission body of said known hinge is also provided with a cavity, in which a damper is housed in a mobile way.
  • Said damper is intended to interact with some abutment surfaces in order to generate damping forces which, upon complete opening of the door, counteract the weight force which acts on the door and, upon complete closing of the door, the force generated by the operating means. In this way one varies the overall force applied to the arm during the closing of the door and the overall force applied to the operating means during the opening of the door.
  • EP 1 039 231 A1 shows a hinge, in particular for oven flaps.
  • the document DE10152907 A1 discloses a hinge, which has all the characteristics indicated in the preamble of claim 1.
  • the transmission body is substantially L-shaped and the transmission pin is rigidly connected to the shorter part of said L.
  • the guiding means comprise, in addition to what is indicated in the preamble of claim 1, a second guiding slit and a guiding pin.
  • This guiding pin is rigidly connected, like the transmission pin, to the L-shaped transmission body, but to its long part.
  • the second guiding slit is placed in the base body and the guiding pin is inserted in it in such a way that, upon the reciprocal rotation between the base body and the arm, the guiding pin slides in said second guiding slit.
  • the reciprocal rotation between the base body and the arm is thus controlled at all moments both by the sliding of the transmission pin in the first guiding slit and by the sliding of the guiding pin in the second guiding slit.
  • the simultaneous action of the two guiding slits allows to determine, thanks to their shape and extension, a precise regime of the reciprocal rotation between the base body and the arm.
  • the sliding of the transmission pin in the first guiding slit is particularly useful to carry out the reciprocal rotation
  • the sliding of the guiding pin in the second guiding slit is particularly useful to guide the movement of the transmission body along a desired and provided direction.
  • Said known hinge performs its task very well, but the presence of two different guiding slits with the associated transmission pin and guiding pin involves a complex kinematic system, whereby the production costs of such a hinge are high and greater than other known hinges which are simpler from the construction point of view.
  • the aim of the present invention is to propose a hinge of the type indicated at the beginning which is simpler than the known hinges from a construction point of view and which in any case allows to obtain the same results obtainable by the more complex known hinges.
  • the reciprocal rotation between the base body and the arm is thus controlled at all moments both by the sliding of the transmission pin in the guiding slit and by the sliding of the contact surface of the base body on the level guiding surface.
  • the simultaneous action of the guiding slit and of the level guiding surface allows to determine, as in the known prior art case, a precise regime of the reciprocal rotation between the base body and the arm.
  • the sliding of the transmission pin in the guiding slit is particularly useful to carry out the reciprocal rotation and the sliding of the contact surface of the base body on the level guiding surface is particularly useful to guide the movement of the transmission body along the direction of longitudinal extension of the base body.
  • the transmission body comprises two reciprocally parallel parts and with its two reciprocally parallel parts which are provided with reciprocally opposite through-holes, on both sides of the arm to enclose between said two parts at least one section of the guiding slit, wherein the transmission pin is inserted and constrained in the two through-holes, wherein the two reciprocally parallel parts each have a U-shaped cross section, and wherein one of the free legs of each U-shaped part faces the level guiding surface, the U-shaped parts being arranged such that the free legs are directed away from each other.
  • the level guiding surface is made up of an internal surface of the base body 1, it is possible to use for this purpose a surface already present in the hinge. If then, as it is claimed in claim 3, the base body has a box-like cross section, the level guiding surface can be made up of the internal surface of one of the walls forming the base body. And if then, as it is claimed in claim 4, the box-like cross section of the base body is open, the wall of the base body having the level guiding surface can be the one opposite to the open side of the base body.
  • the contact surface it is advantageous that it is made up, as it is claimed in claim 5, of a portion of the external surface of the transmission body, since it is already present in the hinge.
  • the latter is made up, as it is claimed in claim 6, of a portion of the external surface of an intermediate body, which is arranged in a fixed way on a portion of the external surface of the transmission body and is made of a material different from that of which the transmission body is made.
  • the figures show a hinge for connecting the door of a home appliance to the body of the home appliance, but the door and the home appliance are not shown.
  • a hinge comprises a base body 1 and an arm 2, which are connected to each other by means of a hinging pin 3 in such a way that each of them 1,2 is rotatable with respect to the other 2,1 in the two possible directions of rotation around the rotation axis A of the hinging pin 3.
  • the base body 1 is fixed to the body of the home appliance and the arm 2 is fixed to the door.
  • the contrary is also possible, that is to say, it is also possible to fix the arm 2 to the body of the home appliance and the base body 1 to the door.
  • the figures represent the first situation, in which the base body 1 is fixed, since it is fixed to the body of the home appliance, while the arm 2 rotates with respect to the base body 1, since it 2 is fixed to the door.
  • the hinge also comprises operating means and transmission means.
  • the operating means act to generate a force which is used to rotate the base body 1 and the arm 2 with respect to each other towards a first typical reciprocal position, that is to say, that which corresponds to the situation of completely closed door.
  • a first typical reciprocal position that is to say, that which corresponds to the situation of completely closed door.
  • Figure 7 shows a second typical reciprocal position of the base body 1 and of the arm 2, that is to say, that which corresponds to the situation of completely open door, in which the door and, therefore, the arm 2 fixed to it form with the vertical an angle of about 90°.
  • the transmission means interact with the operating means and with the arm 2 both to transmit and apply to the arm 2 the force generated by the operating means and to transmit and apply to the operating means the external force which is applied on the door of the home appliance to rotate the base body 1 and the arm 2 with respect to each other towards their second typical reciprocal position, that is to say, that which corresponds to the situation of completely open door shown for example in figure 7 .
  • the transmission means comprise at least one transmission body 4 and one transmission pin 5.
  • the transmission body 4 is mobile along the direction of longitudinal extension B of the base body 1, which coincides with the section line B-B visible in figure 1 , and on it 4 the operating means act to move it along said direction of longitudinal extension B.
  • the transmission pin 5 is rigidly connected to the transmission body 4 and the arm 2 acts on it.
  • the hinge also comprises guiding means for guiding in the two possible directions of rotation the reciprocal rotation between the base body 1 and the arm 2 around the rotation axis A of the hinging pin 3.
  • the guiding means comprise at least one guiding slit 6, which extends in the arm 2.
  • the transmission pin 5 is inserted in such a way that upon a reciprocal rotation between the base body 1 and the arm 2 it 5 slides in the guiding slit 6 and the transmission body 4, which is rigidly connected to the transmission pin 5, moves along the direction of longitudinal extension B.
  • the guiding means also comprise a level guiding surface 1a, which extends parallel to the direction of longitudinal extension B of the base body 1.
  • the guiding slit 6 extends in length and has edges that are shaped according to curved lines in such a way that during the sliding of the transmission pin 5 in it 6 the force F that said guiding slit 6 transmits to the transmission pin 5, always comprises also a force component Fy that is directed, perpendicularly to the direction of longitudinal extension B, towards the level guiding surface la.
  • the force F and its component Fy have been represented for example, in a qualitative way, in figure 8 with reference for example to the situation of door open at 50°.
  • FIG. 8 shows, with reference to a Cartesian coordinate system X,Y having origin in the rotation axis A of the hinging pin 3 (shown for example in figure 5 ), the middle axis of the guiding slit 6 and the relative position of the centre of the transmission pin 5 in some positions of the door identified by the indicated opening angle.
  • the transmission pin 5 is always on a straight line parallel to the X axis. This is due to presence of the guiding surface 1a, against which the contact surface 4a;4b of the transmission body is pressed.
  • the force F which the guiding slit 6 transmits to the transmission pin 5 always comprises also a force component Fy that is directed, perpendicularly to the direction of longitudinal extension B, towards the level guiding surface 1a, it is meant that such a force component Fy is present, although with a different intensity module, for any opening angle of the door.
  • the level guiding surface 1a is suitably formed by an internal surface of the base body 1. If, as it is shown in the figures, the base body 1 has a box-like cross section, then the level guiding surface 1a is formed by the internal surface of one of the walls that make up the base body 1. If the box-like cross section of the base body 1 is open, then the wall of the base body 1 which has the level guiding surface 1a is the one opposite to the open side of the base body 1, it as it is shown in figure 4 or 10 .
  • the contact surface is formed by a portion 4a of the external surface of the transmission body 4.
  • the contact surface is formed by a portion 4b of the external surface of an intermediate body 8, which is arranged in a fixed way on a portion of the external surface of the transmission body 4 and is made of a material different from that of which the transmission body 4 is made.
  • the transmission body 4 suitably extends, with two of its parts 4c which are reciprocally parallel and are provided with reciprocally opposite through-holes 4d, on both sides of the arm 2 to enclose between said two parts 4c at least one section of the guiding slit 6.
  • a first embodiment provides that the operating means consist of a traction spring 7, see figures 2a and 5 to 7 , which is arranged inside the base body 1 and is hooked with a first end 7a to the base body 1 and with a second end 7b to the transmission body 4.
  • a traction spring 7 see figures 2a and 5 to 7 , which is arranged inside the base body 1 and is hooked with a first end 7a to the base body 1 and with a second end 7b to the transmission body 4.
  • a second embodiment of the operating means provides that the operating means consist of a compression spring 10.
  • the base body 1 has a transverse closing wall with a hole and the transmission body 4 has an elongate part, which extends through said hole and has an abutment-like end.
  • the compression spring 10 is wound around the elongate part of the transmission body 4 and rests with a first end 10a on the transverse closing wall and with a second end 10b on the abutment-like end of the elongate part of the transmission body 4.
  • roller 9 can also be arranged in a freely rotatable way, said roller 9 being in contact with the edges of the guiding slit 6 and facilitating sliding.
  • the transmission pin 5 slides in the guiding slit 6, see figures 5 to 7 , and the transmission body 4 is pulled along the direction of longitudinal extension B and said longitudinal movement causes an increase in the return force of the traction spring 7 or of the compression spring 10, which are progressively more and more respectively stretched or compressed.
  • the opening range between 20°, figure 5 , and 70°, figure 6 , it is possible to reach the balance between the weight force acting on the door and the return force exerted by the traction spring 7 or by the compression spring 10 and the door remains in balance in its open position.
  • the force Fy acting on the transmission pin 5 is transmitted to the transmission body 4, therefore during the longitudinal movement of the transmission body 4 the contact surface 4a or the contact surface 4b of it 4 is pressed against the level guiding surface 1a and the transmission body 4 is forced by the level guiding surface 1a to perform a perfectly rectilinear longitudinal movement along the direction of longitudinal extension B.
  • the base body 1 and the arm 2 are in the situation shown in figure 7 .
  • the opening angle of the door is about 90°, more precisely 86°, because in this situation, too, the transmission pin 5 is not in its end-of-stroke position, but in a position close to it.
  • the return action of the traction spring 7 or of the compression spring 10 is maximum, but the weight force, to which the door is subjected, prevails.
  • the transmission pin 5 slides in the guiding slit 6 in an opposite direction with respect to what occurs during the opening of the door and the movement of the transmission body 4, which is pulled along the direction of longitudinal extension B in an opposite direction with respect to what occurs during the opening of the door, causes a progressive release of the traction spring 7 or of the compression spring 10, which are progressively less and less respectively stretched or compressed.
  • the opening range between 20°, figure 5 , and 70°, figure 6 , in which it is possible to reach the balance between the weight force acting on the door and the return force exerted by the traction spring 7 or by the compression spring 10, therefore the door remains in balance in its the open position.
  • the force Fy is obviously transmitted to the transmission body 4 also during the closing of the door, therefore the contact surface 4a or the contact surface 4b of the transmission body 4 is pressed against the level guiding surface 1a and the transmission body 4, guided by the level guiding surface 1a, performs again a perfectly rectilinear longitudinal movement, without movements perpendicular to the direction of longitudinal extension B.
