Definitions

  • the object of the invention relates to a clamp of those used, for example, in plumbing.
  • Adjustable grippers consisting of two branches which are joined together by means of a hinge bolt and where one of the branches is steplessly adjustable in an oblong window of the other branch, to vary the size of the opening of the clamp.
  • clamps having a mechanism of great reliability, strength and ease of handling to move quickly from a working position (where the jaws of the clamp maintains a constant gap while the legs / jaws mutually rotate to open / close) to a control position (where one leg moves linearly relative to the other in the oblong window).
  • a working position where the jaws of the clamp maintains a constant gap while the legs / jaws mutually rotate to open / close
  • a control position where one leg moves linearly relative to the other in the oblong window.
  • the clamp which is the subject of the invention provides a more simplified construction by eliminating the hoop which according to the preamble of claim 1 is inserted between the lug and the pusher which, at present, is a single piece, which fills the push and fret function.
  • the object of the invention relates to a clamp, those which consist of two branches, a male (10) and another female (20), which carry the respective jaws of the opening; these branches (10), (20) being joined together by a hinge pin (2) which, being constituted by the axis of rotation of the female branch (20), is multi-positionable in a staggered manner in an oblong window ( V) of the male branch (10) to vary the size of the opening of the clamp.
  • the female branch (20) defines a first orifice (O 1 ) and a second orifice (O 2 ) coaxial in which is mounted the hinge pin (2) which comprises a toothed lug (1) which may or may not mesh with a toothing (101) defined in the oblong window (V) of the male branch (10).
  • the female branch (20) has a lateral protuberance (P) in which a lateral mortise (6) has been made, coaxial with the two orifices (O 1 ), (O 2 ) of the female branch (20).
  • the hinge pin (2) defines, at one end, a head (C 2 ), with a perimetral boss (22) and an internal seat (21) and, at the other end, a threaded zone (23). .
  • the boss (22), the seat (21) and the threaded zone (23) successively have a smaller diameter: the boss (22) of larger diameter than the seat (21), both of larger diameter that the central area of the axis (2) and all larger diameter than the end zone threaded (23) -though this geometry is not limiting and its alteration does not change the essence of the invention-.
  • toothed lug (1) in the central region of the shaft (2) which abuts laterally against the seat (21).
  • Said toothed lug (1) has external teeth (11) which may or may not mesh with the conjugate teeth (101) provided in the oblong window (V) of the male branch (10).
  • This pusher (5) coaxially defines an inner mortise (51) and an extension (52) forming an internal orifice (50) and which extends beyond its head (C 5 ), where this internal mortise (51) conforms. ) -see Figures 3 and 4 -.
  • the toothed lug (1) and, at least, the extension (52) of the pusher (5) consist of a material resistant to wear.
  • the orifices (O 1 ), (O 2 ) of the female branch (20) have different diameters and, respectively, conjugate of the axis (2) in its seat area (21) and the extension (52) of the pusher (5).
  • the diameter of the first orifice (O 1 ) is greater than the diameter of the second orifice (O 2 ).
