Abstract

THIS ATTACHMENT, MORE PARTICULARLY CONSTITUTING A HINGE, IS COMPOSED OF TWO ELEMENTS 1, 2, EACH OF WHICH HAS A BODY OF GENERAL SHAPE PARALLELEPIPEDIC 3, 6, EXTENDED BY ONE OR MORE ANCHORING TENSIONS 8. THE BODY 3 OF AN ELEMENT 1 INCLUDES A BORE 4, WHILE THE BODY 6 OF THE OTHER ELEMENT 2 INCLUDES AN ADDITIONAL FINGER 5. THE ANCHORING TONGS 8 ARE PROVIDED, ON TWO OPPOSED LATERAL FACES, WITH TEETH 11 FOR THE HANGING OF THESE TENONS IN THE RECESSES HOUSEHOLDS IN PARTS OF FURNITURE, OR OTHER OBJECTS, TO ASSEMBLE.

  Other known hinges consist of two él6-

  identical elements, each of which consists, on the one hand, of a body forming or receiving the axis of articulation, with a finger or a sleeve, and on the other hand, of a fastening part body and having a thread

  for screwing into one of the pieces of furniture to assemble.

  The manufacture of such hinges is also poorly

  fashionable and long, in addition, the threaded fasteners can easily rotate in the case of parts of nmeubjles not immobilized relative to each other, which makes

  more difficult the assembly of hinge elements between euz.

  The present invention aims to eliminate these drawbacks,

  in: -r: smoothing a fastener easy to manufacture and guaranteed -

an effective anchorage.

  For this purpose, in the fastener which is the subject of the invention,

  of the kind recalled in the introduction, are combined the

  following features: a) each element of this fastener has a shaped body

  general parallelepiped, delimited by a semi-cylindrical wall

  drique at one of its extremities which has a finger o muLid2T11t; b1) the body of each element is.prolong,., the c6: t6 opposite its semi-cylindrical end, by at least one lug of square section or rectangular section, each anchor being provided with teeth, to less on deLx faces

  parallel and opposite sides.

  Such a fastener provided with latching teeth is not only prevented from turning in the part of the wheel on which it is mounted, but it also possesses a very high puncture force and also a high resistance to tearing. moreover, it has a simplified fire design and, consequently, a reduced cost of manufacture, all the coniplicated bending operations and the o ... a ..,
