Definitions

  • hose clamps are known on a rigid tube.
  • a clamping tool of the jaw clamp type is usually used.
  • the present invention relates specifically to a pair of jaws intended to be mounted on the arms of pliers for tightening a collar constituted by a metal band wound on itself, having two end portions each provided with a lug directed substantially radially towards the outside of the necklace.
  • Each jaw of the pair comprises fixing means on one of the arms of the clamp and has a front face intended to cooperate in abutment with one of said tabs of the collar.
  • the front faces of the jaws each have a hollow housing which has a bottom and two walls, respectively lower and upper, projecting from this bottom.
  • the recessed housing of one of the jaws is arranged transversely in the middle part of the front face of this jaw and has a substantially flat bottom.
  • the collar which it is proposed to tighten may be a spring collar, the metal strip of which is wound on itself over more than 360 °, so that the so-called “clamping" operation of the collar actually consists in bring the tabs of the end portions of the strip together, using a clamp-type clamping tool.
  • the diameter of the collar is thus increased which allows, by axial sliding, to engage it on the pipe or the object to be tightened. The cessation of the effort to bring the legs together releases the energy accumulated in the collar which then itself tightens the pipe while trying to regain its initial diameter.
  • the first two of these documents disclose a first type of spring collars whose tabs extend transversely over the entire width of the strip.
  • the third document describes a second type of spring collars in which the first end portion of the band is provided with a central recess and has a wide tab, while the second end portion has a narrow tab which crosses this central recess.
  • the width of the legs differs depending on whether one is interested in necklaces of one or the other type.
  • the present invention aims to remedy these drawbacks and provides a pair of versatile jaws which are capable of being mounted on the arms of a clamp and are suitable for tightening one or the other type of known collars.
  • one of the jaws is of the aforementioned kind, while the recessed housing of the other jaw, called “first jaw”, is arranged transversely in the middle part of the front face of this jaw, and that the bottom of this hollow housing has a substantially planar median recess, leaving in said bottom two substantially flat lateral portions, parallel to said recess and arranged on either side of the latter.
  • the pair of jaws is adapted to the tightening of spring collars of the various known types and mentioned above.
  • one of the legs of a collar cooperates in abutment with the two lateral portions of the hollow housing of the first jaw or with the median recess of this hollow housing, while that the substantially flat bottom of the hollow housing of the second jaw is always adapted to receive the other tab as a stop.
  • the width or transverse dimension of the various elements of the collars is defined as opposed to the longitudinal direction of the bands which constitute these collars.
  • the transverse dimensions of the various elements of one or other of the jaws are measured parallel to the transverse dimensions of the legs of the collars when the latter are engaged in the housings of these jaws.
  • Figure 1 shows a conventional clamp body 1 comprising, pivotally mounted about an axis A, two clamping arms 1a and 1b and two manipulation arms 1c and 1d.
  • the clamp 1 comprises a device 2 for adjusting the minimum spacing of the clamping arms and a device 3 for holding in the closed position.
  • This clamp 1 is a tool for tightening a collar 10, constituted by a metal strip 11 wound on itself, which has two portions terminals respectively provided with a tab 12 and a tab 14, directed substantially radially towards the outside of the collar 10.
  • the collar shown schematically in FIG. 1 is of the type shown in FIG. 2.
  • a pair of jaws 20 and 40 is mounted on the clamping arms of the clamp 1.
  • the first jaw 20 is mounted on the clamping arm 1a and has a front face 22 which cooperates in abutment with the tab 12 of the collar.
  • the second jaw 40 is mounted on the clamping arm 1b and has a front face 42 which cooperates in abutment with the tab 14 of the collar.
  • the second jaw 40 has a front face 42 which has a recessed housing 44 comprising a bottom 46, a bottom wall 47 and an upper wall 48.
  • This recessed housing 44 is disposed transversely in the middle part of the front face 42 of this jaw 40 and its bottom 46 is substantially planar.
  • the first jaw 20 has a front face 22 which itself has a hollow housing 24 comprising a bottom 26, a lower wall 27 and an upper wall 28.
  • the housing 24 is arranged transversely in the middle part of the front face 22 of the first jaw 20.
  • the bottom 26 of this housing 24 has a substantially flat central recess 26a, which leaves two substantially flat lateral portions 26b and 26c, parallel to the recess 26a and arranged on either side of the latter.
  • the reference 28 designates the upper wall of the housing 24, which is constituted by the lower face of a boss formed projecting from the front face 22 of the jaw 20.
  • this wall 28 advantageously has a notch 28a whose dimension transverse is substantially equal to that of the median recess 26a.
  • the boss formed projecting from the front face 22 remains that two prominent lateral surfaces 28b and 28c, disposed on either side of the notch 28a and transversely located substantially opposite the lateral portions 26b and 26c of the bottom of the housing. 24; their transverse dimension is substantially equal to that of each of the lateral portions 26b and 26c.
  • first jaw 20 is symmetrical with respect to an axis Y (FIG. 7) perpendicular to its transverse direction. The same goes for the second jaw 40.
  • the two tabs 12 and 14 of the collar 10 have the same width, which is itself substantially equal to that of the strip 11.
  • the two tabs 12 'and 14' of the collar 10 'shown in Figure 3 are of different widths. Indeed, one of the end portions of the strip 11 'wound on itself has a wide tab 14' and a central recess 15. The other tab 12 ', called “narrow tab” is carried by a strip portion which passes through this recess 15 and whose width is substantially equal to that of the latter.
  • the jaws 20 and 40 are adapted to the clamping of the collar 10 of Figure 2.
  • the tab 12 of this collar indeed cooperates in abutment with the two lateral portions 26b and 26c of the bottom 26 of the housing in the hollow 24 of the first jaw 20, bearing, if necessary, on the two lateral surfaces 28b and 28c, while the tab 14 cooperates in abutment with the bottom 46 of the hollow housing 44 of the second jaw 40.
  • this collar 10 has diametrical symmetry and that the two jaws 20 and 40 are indifferently adapted to one or the other of its legs 12 and 14.
  • the lateral surfaces 28b and 28c arranged on either side of this notch 28a cooperate with the rear face of the tab 12 of the collar 10 when the latter is tightened.
  • the prominent lateral surfaces 28b and 28c have, towards their front end portion, a convexity adapted to the curvature of the rear face. 12a or 12b of these legs.
  • the housing 24 of the first jaw 20 advantageously comprises two side walls 29 and 30.
  • the side walls 29 and 30 are located transversely beyond the side portions 26b and 26c of the bottom 26 of this housing, and their spacing corresponds substantially to the width of the legs of the collar of the first type considered.
  • the jaws 20 and 40 are also suitable for tightening the collar 10 '.
  • the narrow tab 12 'of this collar cooperates in abutment with the median recess 26a of the bottom 26 of the hollow housing 24 of the first jaw 20, while the wide tab 14' cooperates in abutment with the bottom 46 of the housing 44 of the second jaw 40.
  • FIG. 5a which shows the first jaw 20, it can be seen that the transition zone between the median recess 26a and each of the two lateral portions 26b and 26c consists of a step 26 'which, when the collar is tightened 10 ', contributes to the lateral setting of its narrow tab 12'.
  • each of the two tabs 12 'and 14' tilts so that the angle it forms with the bottom of the housing of the corresponding jaw decreases.
  • the notch 28a makes it possible to prevent the upper wall 28 of the housing 24 from constituting an obstacle to the pivoting movement of the narrow tab 12 '.
  • the upper wall 48 of the housing 44 of the second jaw 40 advantageously has a median extension 48a whose transverse dimension is substantially equal to that of the median recess 26a and the 'notch 28a of the housing of the first jaw.
  • each of these two recessed surfaces cooperates with each of the two portions 14'a and 14'b of the wide tab 14' situated on either side of the recess 15.
  • the extension 48a and, more precisely, its front end part can cooperate with the rear face 14a of the tab 14.
  • the extreme front part of the median extension 48a may have a convexity adapted to the curvature of the rear face 14a of this tab 14.
  • the upper and lower walls of the housings 24 or 44 are advantageously inclined at an angle greater than 90 ° relative to the bottoms of these housings.
  • the lower wall 27 of the housing 24 of the first jaw 20 advantageously has a median recess 27a, of width substantially equal to that of the median recess 26a.
  • Two lateral parts 27b and 27c of this lower wall 27 remain on either side of the median recess 27a (FIG. 5a). The cooperation of the end of the narrow tab 12 ′ of the collar 10 ′ with the median recess 27a defines the extreme downward position of this lug when this collar is tightened.
  • each jaw 20 or 40 on the corresponding clamping arm 1a or 1b of the clamp 1 have a stud 25 or 45 projecting from the rear face 23 or 43 of the jaw considered.
  • This stud engages in an opening 4 of the corresponding clamping arm of the clamp. It has a circular groove 25a, 45a in which a circlip 25b is placed in order to maintain the jaw in the mounted position.
  • each jaw is prevented by means of a protuberance 23a, 43a from its rear face 23, 43, cooperating in complementary shape with a recess 4a in the corresponding arm of the clamp.
