Definitions

  • the present invention relates to a ratchet device.
  • invention in object is advantageously used in upholstered furniture field in order to allow the controlled movement of movable parts, such as headrests, footrests, armrests or equivalent elements furniture, sofas, armchairs or the like, to which the following description explicitly referes to without thereby losing in generality.
  • movable parts such as headrests, footrests, armrests or equivalent elements furniture, sofas, armchairs or the like, to which the following description explicitly referes to without thereby losing in generality.
  • One of the mentioned wings of the device is fixed on a portion or edge of the headrest , while the other wing is fixed to a portion or edge of a fixed part, the backrest of the sofa , thereby allowing to realize a relative movement of rotation and opening in the upright position of the headrest relative to the backrest in such a manner as to raise and support in an optimal way the head of the user sitting on the sofa.
  • the structure of the ratchet devices of the known type described above is such as to allow a rotation of the opening of a wing with respect to the other wing of a limited angle with respect to the initial closed position, specifically not more than 90 degrees, or between a closed position in which the two wings are arranged orthogonal to each other, and a position of complete opening in which the two wings are arranged aligned with each other and from the side opposite the hinge.
  • the scope of the present invention is to provide an improved device able to be applied to a sofa or armchair and allow to realize a lifting handling of the headrest relative to the backrest of the sofa or armchair with an angle even greater than 90 degrees.
  • D globally indicates a ratchet device adapted to be used preferably but not limited in the upholstered furniture industry for the movement of movable parts, such as the headrest, or equivalent elements furniture, sofas, armchairs or similar ( known and not shown ).
  • the device D includes an element 1 with two wings 2 and 3 hinged together in correspondence of a central portion 4 of the element 1 via a coupling ratachet mechanism 5.
  • the wings 2 and 3 are therefore movable in rotation each other around a fixing pin 6 with a movement of opening / closing generated by the mechanism 5 from which the pin 6 is part of.
  • the mechanism 5 also comprises the following elements, arranged in pairs opposite side with respect to the two wings 2 and 3 and fixed between them perfectly fitting into a single assembly by means of locking rivets 7 and 7a:
  • the pawls 18 are adapted to engage in the teeth of a single sector S of the mechanism 5 defined by the alignment of the sectors 9 and 9' as a result of the coupling of the semi-circular plates 8 and 8' between the wings 2 and 3, so forming a two-way moving and locking ratchet system.
  • the wing 2 has a longitudinal dimension greater than the wing 3, and it is provided with two quarries slits 26 identical to the aforementioned slits 16,16' described above, of a passage hole 27 for the pin 6, and of a pair of holes 28 for the passage of respective rivets 7 and which blocks the cited wing 2 between the plates 14,14'; the wing 3 has a pair of holes 29 for the passage of respective rivets 7a and which blocks the cited wing 3 between the plates 8,22, and 8',22'. Both the wing 2 and wing 3 also have a series of holes 30 for the attachment in known manner to fixed parts and / or furniture of sofas or armchairs.
