Definitions

  • the invention relates to a direct tension buckle to constitute a belt with a strap of vegetable or synthetic textile.
  • buckles There are many models of such buckles. Among these all loops with a self-locking device with bars sliding in a frame are suitable for retaining low loads, but they let the strap slip if the load is too heavy or if there is vibration. There are also other more elaborate and currently widespread models, the buckles then being constituted by a frame-shaped casing which includes a rear bar for fixing one end of the strap by sewing and a front bar, constituting a notched static jaw. , on which the strap slides to ensure its tension and stop.
  • the two side walls of the frame are vertical - and have a hole right through, for the introduction of an axis intended to receive in articulated assembly a self-tightening jaw by eccentricity and notched, generally in diamond point, essential to ensure its attachment to the strap and thus allow its retention by the eccentric movement of the jaw.
  • a relatively strong spring keeps the eccentric jaw in permanent pressure on the static jaw, which damages the strap when it slides for its tension.
  • a lever included in the self-tightening jaw is provided to be actuated manually. This lever allows you to cancel the spring pressure in order to spread the jaws to introduce the strap into the buckle and remove it. Due to the variations in thickness of the straps that can be used and the shape of the tightening, these loops have a relative efficiency and offer no security.
  • the present invention relates to a loop of a presentation on certain points substantially identical to certain types of the example described above.
  • this new loop also consists of a frame-shaped casing comprising side walls positioned vertically.
  • This frame includes one or two rear bars for fixing one end of the strap by sewing or self-tightening according to a determined passage of the strap on the two bars.
  • Another bar, located at the front of the frame constitutes a static jaw similar to the buckle model described above.
  • the technical difference, object of the invention lies in the design and operation of the movable, self-tightening jaw, which generates a logical action in the cooperation of the two jaws and, therefore, an absolute clamping effect in efficiency. and the intensity of which is always a function of the charge to be retained.
  • the self-tightening movable jaw is made up of a part with a circumference in split form.
  • a fraction is semi-cylindrical, and another fraction forms a relatively triangular relief, one of the faces of which constitutes a movable jaw.
  • the strap takes its support directly on the static jaw
  • the strap wraps and takes its support on the movable jaw in a determined direction to then engage and slide parallel between the two jaws which ensures a very free sliding of the strap and thus allows the user to obtain maximum tension.
  • the effectiveness of the tightening of the strap between the two jaws to ensure its stop in blocking is due to the support and the friction effect of the strap on the semi-cylindrical part of the movable jaw.
  • This friction and this support generate a multiplication of forces in the action of the lever thanks to the maximum eccentricity of the semi-cylindrical fraction.
  • the tensioning operation of the strap causes an opposite effect of training of the movable jaw which completely frees the passage of the strap between the jaws without for this completely entraining it because of its eccentric articulation.
  • the strap is unlocked by the hinge pin which is made integral with the self-tightening movable jaw and which forms a lever outside the frame intended to be actuated by hand.
  • a judiciously positioned spring is provided to keep the jaws in permanent contact.
  • the loop according to the invention consists of a casing 1 in the form of a frame, comprising two bars 2, 3 situated at the rear of the frame to allow fixing in self-tightening and according to a determined passage. of the strap 4 on the bars 2 and 3, allowing an adjustment in length of the strap.
  • the strap could be attached to the bars 2, 3 by sewing.
  • a fraction 9 is of semi-cylindrical shape and another fraction 10 forms a practically triangular relief of which one of the faces constitutes a movable jaw 11.
  • the semi-cylindrical fraction 9 is traversed longitudinally by a bore 12, disposed near its upper edge, which receives an axis 13 coming to articulate in the holes 7, 7 'of the vertical walls 6, 6'.
  • This design shows schematically a triangle which has as its fulcrum the articulation axis 13 and whose semi-cylindrical part furthest from the axis 13 constitutes a lever which ensures, automatically and multiplied, the clamping of the jaw 11 on the jaw 5 and, consequently, an absolutely effective tightening of the strap 4 between these jaws.
  • the jaw 11 is unlocked by a control lever 14 which is produced as an extension of the axis 13 and is intended, for this purpose, to be tilted in the direction of the arrow D in FIG. 1.
  • the user pulls on the free end thereof in the direction of the arrow C in FIG. 1, which has the effect of rotating the element 8 in the direction opposite the arrow B by completely freeing the passage of the strap between the jaws and thus avoiding on the one hand the effort of the user and, on the other hand, the wear of the strap.
  • the eccentric axis of rotation 13 of the element 8 has in its center a flat 15 (see Figure 1) which, by crimping the bore 12 of the element 8, ensures the locking of the axis 13 on the element 8.
  • the locking of the axis 13 could also be ensured by providing an appropriate profile for this axis (for example with hexagon, square, etc. .0.).
  • the element 17 has a flat jaw 20 articulated around an axis 21. This assembly makes it possible, when tightening the strap 4, to obtain excellent parallelism between the fixed jaw 22 and the movable jaw 20. This increases the surface tightening strap and provides a very effective tightening without risk of deterioration of the strap.
  • a torsion spring 23 wound around the eccentric axis of rotation 24 and one end of which rests in a notch 25 in the side wall of the loop 16. The role of this spring 23 is to keep the jaws in permanent contact.
