Definitions

  • the known tighteners have various disadvantages. It is very difficult and in many cases impossible to turn the nut on the :adjusting bolt merely with the fingers when it is very cold, particularly when snow or ice adhere to the tightener. Besides, the threaded bolt is fairly susceptible to external action, such as impact or the like, which is often inevitable during skiing and the manipulation lof the skis. When the threaded bolt is only slightly bent or when a single thread turn has .been squeezed, the adjusting bolt can no longer serve its function. Continual shakes, such as occur when the skis are being carried on a luggage carrier on the roof of a car, may result in an unintended rotation of the nut so that the setting of the tightener is varied or the nut may even be lost. Besides, the adjustment of the known tighteners is relatively troublesome, particularly when a relatively large adjustment, e.g., by a plurality of shoe .sizes is required.
  • a front tightener for ski bindings in which the tightener lever is pivoted to a bracket, which is adjustable in the longitudinal direction of the ski, and from which bracket an adjusting element extends forwardly, which bears on a retaining bracket secured to the ski, these disadvantages are avoided according to the invention in that the adjusting element has a number of supporting discs or the like, which are capable of a limited displacement on the adjusting element in the axial direction of the latter, and th-at the adjusting element has at its front end an abutment, the retaining .bracket is provided with a groove having a width which is larger than the diameter of the :adjusting element and smaller than the diameter of the supporting discs, and the retaining bracket is further provided with means for detachably retaining the adjusting element.
  • the ⁇ adjusting element may consist of a wire cable and carry :at its front end a supporting nipple. It is particularly suitable if the supporting discs are do'uble-frustoconical and that wall of the retaining bracket which is at right angles to the longitudinal direction of the ski and formed with the groove has a frustoconical recess lat least on its front face.
  • a helical compression spring may be disposed between the rearmost supporting disc and the bracket which carries the tightener lever.
  • the supporting discs mounted on the adjusting element for .a limited movement co-act with the retaining bracket to enable a particularly simple adjust-ment of the position of the tightener in the longitudinal direction of the ski.
  • a prolonged turning of a mitted from the tightener to the retaining bracket by fice element with the supporting discs may be removed from the groove ⁇ of the retaining Vbracket and may be inserted into the same at any desired other point.
  • two adjacent supporting discs will be forced apart and the tensile force exerted upon the tightener will be transmitted from the tightener to the retaining bracket by means of the adjusting element, its front abutment, and the supporting discs disposed between the front abutment and the retaining bracket.
  • This force will lbe effective as a compressive force between the abutment and the retaining bracket.
  • the supporting discs m-ay have any desired thickness, an adjustment in very line steps is enabled without involving an increase in the time required for adjustment.
  • the susceptible threaded bolt which can no longer be operated by hand after the slightest damage, has been eliminated. A spontaneous change of the setting as a result of shakes and the like is no longer possible.
  • the assembly is greatly facilitated because the retaining Ibracket can easily be mounted as a separate part of the tightener.
  • the adjusting element consists of a wire cable, which carries a supporting nipple at its front end, any damage to the adjusting element will be virtually precluded because the element can yield to any external action.
  • the flexibility of the wire cable greatly facilitates its removal from and insertion into the retaining bracket.
  • the Hexible design of the adjusting element has the further advantage that any ice covering which may have formed will readily be broken during the adjustment. If the supporting discs are double-frustoconical, as has been mentioned above, zand that wall of the retaining bracket which is formed with the groove has a Afrustoconical recess, a particularly simple retention of that supporting disc which engages the bracket will be achieved.
  • the supporting discs must be widely spaced apart and will then snap into the recess which is provided at least on the front face so that the discs can no longer detach spontaneously, particularly if the ab-ove-mentioned helical compression spring is arranged between the rearmost supporting disc and the bracket which carries the tightener lever.
  • successive groups of supporting discs may have different features. These different features may consist, e.g., of different colors, different forms of the rims, or the like, and greatly facilitate the adjustment because they result in a clear arrangement Vof the entire .adjusting range.
  • the various groups may correspond each, e.g., to a shoe size.
  • the wire cable may have at its rear end a cylindrical nipple, which can be introduced through a corresponding opening of the bracket which carries the tightener lever into a guide bore, which is formed in this bracket and the front end -of which is provided with a constriction for retaining the nipple.
  • a reliable retention of the adjusting element on the tighener bracket is ensured in such a manner that the adjusting element is parallel to the axis.
  • the bracket which carries the tightener lever need not be guided on the ski. If it is not guided, its bottom face has suitably rearwardly flaring extensions.
  • the bracket carrying the tightener lever may ybe guided in known manner in a sliding guide secured to the ski.
  • the returning bracket may con-tain according to the invention a spring-loaded detent ball, which coacts with a longitudinal groove formed in the inner side wall of the tightener lever so that the tightener lever is effectively locked against an unintended opening.
  • FIG. 1 is a side elevation showing the front tightener according to the invention in closed position.
  • FIG. 2 is a top plan view showing the tightener of FIG. l the retaining bracket below the tightener lever being indicated by broken lines.
  • FIG. 3 shows the front tightener according to the invention in a partly open condition.
  • FIG. 4 is a detail sectional view taken on line IV-IV of FIG. 5 and showing the retaining tbracket and a portion of the adjusting element with the supporting discs shortly before their insertion in-to -the retaining bracket and in the supporting position on the retaining bracket.
  • FIG. 5 shows the retaining bracket in an elevation taken in the longitudinal direction of the ski.
  • FIG. 6 illustrates plan views of typical shapes for the supporting elements which may be used for coding.
  • FIG. 7 lillustrates a section taken along line 7-7 of FIG. 1.
  • a yokelike tension member 2 Pivoted to the tightener lever 1 is a yokelike tension member 2, which carries the tension cable 3.
  • the tightener lever 1 is pivoted by a pin 4 to a bracket 5.
  • the pin 4 lies above the pivot points 6 of the tension element 2.
  • the bracket 5 shown in broken lines in FIG. 2 has a supporting surface, which ilares rearwardly in triangular configuration and is not connected lto the ski by screws or the like.
  • the bracket 5 may be guided in a sliding guide 23 known per se.
  • the bracket 5 has an open-topped opening 7, which opens into a vertical groove in the front face of the bracket 5. This groove is not apparent from the drawing.
  • the opening 7 has a borelike portion, which is formed with a oonstricted front end and accommodates a nipple 8 carrying a exible steel wire cable 9.
  • the cable 9' is provided at its front end with a supporting nipple lil.
  • Supporting discs 11 are arranged on the cable 9 like beads on a string. This means that the discs are not connected to each other.
  • the discs are urged forwardly towards the supporting nipple 11i by a helical spring 13, which is provided between the bracket 5 and the rearmost supporting d-isc 12, which is reinforced.
  • each group of four supporting discs 11 dilers in color from the succeeding group of tour.
  • the double-frustoconical supporting discs 11 of the adjusting element 9 co-act with a retaining Ibracket 14, which is secured to the ski 16 by the screws 15.
  • the retaining bracket 14 consists of a baseplate 17, an intermediate wall 18, which is at right langles to the longitudinal direction of the ski, and -two triangular side walls 19.
  • the wall 18 has frustoconical recesses on lboth sides, as is shown particularly in the sectional view of FIG. 4.
  • the wall 1S has a groove 20, which extends from the top beyond the center of the frustoconical recess.
  • the upper portion of the wall 18 tapers to a cutting edge 2.1.
  • FIG. 6 illustrates typical shapes for the supporting elements, the circular shape Ebeing the preferred embodiment.
  • FIG. 7 illustrates a means whereby the tightening lever may be locked in the closed position.
