Definitions

  • the present invention relates to a self-closing hinge structure for doors and the like.
  • hinges for the doors of items of furniture can be currently found, among which are those formed by two cylindrical elements axially and rotatably associated by a pivot and each provided with members for respectively fixing the cylindrical elements to the door and to the item of furniture, at the side thereof to be hinged.
  • the closure of the door is achieved, at the side thereof opposite the hinges, by magnets associated with the inner part of the item of furniture which, upon closure of the door, make contact with ferrous elements associated therewith.
  • this type of hinge also has the disadvantage that the magnetic closure is not reliable.
  • hinges currently used are those of the concealed type, mounted internally, which besides implying a considerable constructive complexity, have high production costs.
  • the aim of the present invention is to provide a hinge structure for doors and the like which is self-closing and has compact dimensions.
  • An important object of the invention is to provide a hinge structure which is capable of withstanding the stresses due to the opening and closure of the door.
  • Another object of the invention is to provide a hinge structure constituted by a reduced number of components and which is easy to assemble.
  • Still another object of the invention is to provide a hinge structure which is easy to apply to furniture in general.
  • Not least object of the invention is to achieve low cost with conventional plant and equipment.
  • a self-closing hinge structure for doors and the like which is characterized in that it comprises two members, mutually rotatively coupled by elastic means, said members being also associated by a rigid means hindering their mutual rotation, said two members being also provided with means for coupling to the ends to be hinged.
  • said hinge may be provided with elements for stiffening the structure.
  • the self-closing hinge comprises a monolithic female element 1 advantageously made of plastic material and being rotative­ly coupled to a male element 2, also advantageously made of plastic material.
  • the female element 1 is essentially parallelepipedal in shape and defines a longitudinal surface, indicated by the reference numeral 3, having formed thereon two semicylindrical lugs, respectively 4 and 5, which extend parallel to the longitudinal axis of said element 1 and are spaced apart so as to define a seat 6 adapted for accomodating said male element 2.
  • Each of said semicylindrical lugs has formed therein a through hole 11,12 which are co-axial and arranged symmetrically with respect to the center of the longitudinal extension of said seat 6, and each have a cylindrical portion 13 adjacent to said center and by a conical portion 13a, flared towards the side opposite to said center.
  • the surface 3 furthermore has formed thereon a longitudinal concave recess 14 which is radiused at its outer corners to rounded borders 15 and 16.
  • Said female element is longitudinally traversed in an eccentric or off-center portion thereof 17 by a cylindrical hole 18, located in such a position that a dowel 19, expediently made of tempered steel, contained therein, protrudes slightly, its outer surface 20 protruding from said concave recess 14 in the portion comprising said seat 6.
  • the dowel 19 also advantageously increases the rigidity of the hinge structure.
  • a transverse concave recess 21 adjacent to said seat 6 is provided on the female element 1 in a substantially central position at a transverse portion 22 opposite to said portion 17.
  • the male element 2 is elongated in shape, has such a length as to be exactly contained in said seat 6 of said female element 1. From a central portion of the male element 2 protrudes a cylindrical tab 23, extending perpendicular to the longitudinal axis of the male element 2 and having formed thereon transverse annular grip notches 24.
  • the cross section of said male element 2 is essentially oval and defined by the intersection of two closely set substantially circular profiles, respectively 25 and 26.
  • the first profile 25 is shaped complementarily to said concave recess 14 and the second profile 26 advantageously corresponds to the outer profile of said semicylindrical lugs 4 and 5.
  • the cylindrical tab 23 is positioned such that when the element 2 is contained in said seat 6 it is substantially perpendicular to said tabs 8 and 9.
  • Said male element 2 is longitudinally traversed by a hole 17 having an axis coinciding with the axis of said profile 25 and with the axis of said holes 11 and 12 of said tabs 8 and 9 and having a cylindrical central portion 28 and two outwardly flared conical end portions 29 and 30.
  • the profile 25 has a concave recess 31 which has a shape corresponding to said outer surface 20 of said tempered steel dowel 19.
  • the elements 1 and 2 are rotatively coupled by an elastic pivot pin 32, advantageously made of tempered steel and being inserted in said holes 11, 12 and 27.
  • the operation of the hinge is as follows: when the coupling of the elements 1 and 2 to the pivot pin 32 has occurred and the dowel 19 has been inserted, they can mutually rotate about their common axis only if the obstacle constituted by the dowel 19, shaped complementarily to the concave recess 31, is overcome.
  • the hinge structure is advantageously of compact dimensions and has a rigid structure constituted by a reduced number of components.
  • the materials employed, as well as the dimensions, may be any according to the requirements.
