Definitions

  • the object of this invention is a new manual tube bender.
  • the tube bender object of this invention is one of those structured by a main frame bearing corbouterolles (S), whose "main frame has in articulation (A 1 ) a lever (5), the assembly having the appearance general manual tool similar to that of pincers or pliers -see figure 1 .
  • this main frame has a head (11) having counterboot (S) and a handle (12) having splines (3) in which the bender (C) is arranged .
  • the counterbooters (S) and the bender (C) are replaceable by a quick engagement mechanism described below.
  • the head (11) and the handle (12) have means for mounting them in a fitted manner; these means being, in particular, sets of rods (13) in one of the head elements (11) or handle (12) - which fit snugly in the conjugate housings of the other head element (11). ) or handle (12) - -see figure 6 .
  • splines (3) linearly movable guided relative to the handle (12).
  • These grooves (3) have a first rack and pinion (31) and a second rack and pinion (32) on the two opposite faces and mount the bender (C) on its front end and on its end.
  • posterior having a spring (4) tending to fold the splines (3) to their initial position of rest, for this it clings to the ends (41), (42) corresponding to the main body (1) and to same grooves (3) -see figure 3 .
  • a unidirectional thrust trigger (6) is articulated (A 2 ) whose toothing (6a) engages / is triggered in the toothing-rack (31) splines (3) if it is actuated, respectively, by the lever (5) or by a balance spring (61) -see figure 3 .
  • the two traction springs (4), (7) are concealed by a cover (12a) which is mounted on the handle (12) using, for example, a screw (121) -see figure 3 . It is irrelevant and incidental to the effects of the invention, that the springs (4), (7) mount their corresponding end (41), (71) on the handle (12), as in the case of the spring (4) or in the cover (1 2a), as does the spring (7) -see figure 3 .
  • lever (5) is hinged (A 1 ) to the handle (12) or the cover (12a); in the embodiment shown in the figure 3 the lever (5) is hinged to the cover (12a).
  • a unidirectional retention trigger (2) whose toothing (2a) engages / is triggered in the second toothing-rack (32) of the grooves (3) being actuated respectively by a push spring (21) or by the worker himself -see figure 3 .
  • the curvatures (S 1 ) of the buttresses (5) and (Ci) of the bender (C) are fixed, conjugate and different for each diameter of tube to be bent.
  • a structuring is available, for the assembly / disassembly, it is enough to embouch the lock (P) in the grooves and to rotate it on 90 ° so that it is retained by the action of the spring (R).
