Definitions

  • the present invention relates to a return device for a door handle.
  • a handle group usually comprises a handle suitable for being gripped and a return device for attaching the handle to the door and returning it from a lowered position to the rest position, usually horizontal.
  • the purpose of the present invention is to make a return device for a handle which resolves the aforesaid problem and which overcomes the drawbacks of the prior art.
  • FIG. 1 shows a perspective view of a handle group
  • FIGS. 2a 2 2b show a rear ground view of a handle group containing a return device according to the present invention.
  • reference numeral 1 globally denotes a handle group for a door.
  • the handle group 1 comprises a handle 2 rotating around a rotation axis X between a normally horizontal rest position and an opening position, inclined downwards compared to the horizontal position.
  • the handle 2 comprises a shank 4 extending along the rotation axis X and a grip 6, connected to the shank, for example in one piece with it, extending in a direction incident to the rotation axis, for example perpendicular to it.
  • the grip is suitable for being gripped by a user to move the handle from the rest position to the opening position.
  • the handle group 1 comprises, in addition, a return device 10 able to attach the handle 2 to the door and to return it from the opening position to the rest position.
  • the return device 10 comprises a case 12 comprising a base wall 14 and an annular side wall 15, projecting axially from the base wall, so as to form an inner compartment 16.
  • the shank 4 of the handle crosses the front wall 14, projecting into the compartment 16 with its terminal section 4' or by means of a square pin.
  • the case 12 comprises at least one return boss 18 contained in the compartment 16; for example, the return boss 18 projects axially from the base wall 14.
  • the return device 10 comprises an elastic element 20, contained in the compartment 16, usually positioned coaxially to the shank 4.
  • the elastic element 20 is a spiral spring, engaged at one end, for example, a first end 22 with the return boss 18, and at the other with the section of the shank 4 projecting into the compartment 16.
  • the elastic element 20 constantly biases the shank 4 from the open position to the rest position thereby forming a type of return mechanism.
  • the return device 10 comprises, in addition, means of attachment for attaching the case 12 to the door.
  • the means of attachment comprise attachment holes 24, 26 positioned diametrically opposite, which cross the base wall 14, for screwing up the attachment screws.
  • attachment holes 24, 26 are made in attachment bosses 28, 30 contained in the compartment 16, for example projecting radially from the side wall 15 of the case 12.
  • the return device comprises stop devices able to form an abutment for the angle of the shank in the rest position.
  • the stop devices comprise a stop element 32 joined in rotation to the shank 4, for example inserted on a section 4' of the shank 4, able to form an end stroke abutment for the rotation of the shank when it reaches the rest position.
  • the stop element 32 is composed of a crown connected to the shank 4, from which a tooth 34 projects with a radial extension.
  • the stop devices also comprise a stop boss 36, contained in the compartment 16, attached to the base wall or side wall.
  • the stop boss 36 has a radial extension.
  • the stop boss thereby presents a striking surface 36', facing the tooth 34.
  • the return device 10 comprises, in addition, adjustment devices able to regulate the angular position of the end stroke of the shank.
  • the adjustment devices can be used to vary the angular position in which the shank abuts against a fixed element, thereby defining the rest position.
  • the adjustment devices comprise a threaded bead 40 which can be screwed into the stop boss 36, in a circumferential direction.
  • the bead 40 projects from the striking surface 36' of the stop boss 36 in an adjustable manner, so that the projecting part defines an adjustable abutment for the tooth 34.
  • the bead 40 is sprinkled with a polymer able to limit the self-loosening of the bead, such as a polyamide polymer, for example of the Eslok® type.
  • a polymer able to limit the self-loosening of the bead such as a polyamide polymer, for example of the Eslok® type.
  • the bead 40 is of the type with a pressure ball.
  • Such types of beads have a tubular body which a ball and a compressed spring are inserted in, pressing the ball so as to make it terminate at the extremity of the bead body.
  • the bead with pressure ball makes it possible to lessen the impact between the stop element and the extremity of the bead, where the ball is.
  • the two attachment holes 24, 26 are positioned so that the straight line passing through their centres is substantially horizontal; in addition, the bead 40 comes out of the stop boss 36 so that the tooth 34, abutting against it, positions the grip 6 horizontally.
  • the adjustment of the bead 40 makes it possible to absorb manufacturing and assembly deviations of the components and deviations in the realisation of the holes on the door, so that the grip 6 of the handle 2 is horizontal.
  • the grip 6 can thus be brought back to the horizontal rest position, as desired.
  • the return device resolves the problem spoken of, and specifically makes it possible to mount the handle so that the grip is perfectly horizontal. Furthermore, it makes it possible to adjust the position of the grip, putting it back into a horizontal position even when, on account of play, it has begun to incline, usually upwards.
