  • a transverse bolt is attached, which can be inserted into a pair of two pairs of recesses of the opposite bearing block.
  • This version is somewhat cumbersome to use and has the further disadvantage that a continuous adjustment of the effective cable length is not possible here.
  • the invention has for its object to eliminate the disadvantages of the known designs and to provide a tightening closure that is simple in construction on the one hand and that can be continuously adjusted on the other.
  • the second bearing block has a transverse wall provided with a passage for the cable and that the receiving part is designed as a threaded sleeve into which a threaded plug fastened at one end of the cable is screwed, on the one hand a simple construction of the tension lock is brought about and on the other hand a stepless Allows adjustment of the effective length of the cable.
  • the features of claim 2 facilitate the insertion of the cable into the transverse wall, and the guidance of the threaded sleeve in the bearing block is improved.
  • claim 3 reliably prevents the end of the cable from falling out of the bearing block.
  • the features of claim 4 allow partial coverage of the top of the sleeve.
  • the measure of claim 5 facilitates the insertion of the sleeve into the bearing block at the end of the closing process.
  • the measure of claim 7 doubles the available adjustment range of the effective cable length.
  • the manufacture of the receiving part is cheaper in that only the core has to be made of metal, whereas the jacket is injection molded from plastic.
  • the subject matter of claim 12 also aims in this direction.
  • the measure of claim 11 facilitates the twisting of the receiving part.
  • the subject of claim 13 facilitates the lifting of the intermediate member from the locking recesses.
  • the measure of claim 14 ensures a secure mounting of the receiving part within the frame-like intermediate member.
  • Figures 1 to 3 show a first embodiment of the invention, wherein Figure 1 shows a vertical longitudinal central section without a second bearing block, Figure 2 shows a reduced cross section through a ski boot when closed and Figure 3 shows a similar cross section when the closure is open. 4 shows a variant of the first embodiment. 5 shows a cross section through the ski boot in a second embodiment with the closure open. 6 shows an enlarged longitudinal central section through this closure, the individual elements being shown in an exploded state for the sake of clarity.
  • Fig. 7 is an enlarged cross section along the line VII-VII in Fig. 6.
  • Fig. 8 is a reduced cross section through the ski boot with the closure closed.
  • FIG. 1 to 3 show a first embodiment of the invention, wherein Figure 1 shows a vertical longitudinal central section without a second bearing block, Figure 2 shows a reduced cross section through a ski boot when closed and Figure 3 shows a similar cross section when the closure is open. 4 shows a variant of the first embodiment. 5 shows a cross section through the ski boot in a second embodiment
  • FIG. 9 shows a third embodiment of a tightening closure in a vertical longitudinal central section and FIG. 10 shows a plan view of the second bearing block in the direction of the arrow X in FIG. 9.
  • FIG. 11 shows a detail in section along the line XI-XI in FIG. 10 and a cross section along the line XII-XII in FIG. 10 is shown in FIG.
  • the tightener shown in Figures 1 to 3 is designated 1 in its entirety. It consists of a first bearing block 2, which is fastened to a first locking tab 3a of a ski boot 3 by rivets (not shown), and a second bearing block 4, which is arranged on a second locking tab 3b opposite the first locking tab 3a.
  • a clamping lever 6 is pivotally mounted on its axis 5 with its fork-shaped end 6a.
  • this end 6a there is a further axis 7 at a distance from the axis 5, by means of which an approximately cuboid connecting piece 8 is articulated.
  • This connecting piece 8 has a threaded bore 8 a running in the direction of its longitudinal axis, which is used to receive a first screw plug 9.
  • a cable 10 is welded to this at one end. The cable 10 is encased in a plastic jacket, not shown.
  • the other end of the cable 10 is connected to a second threaded plug 12 which is screwed into a sleeve 13 with an internal thread.
  • the outer surface of the sleeve 13 is partially provided with knurling 13a.
  • the sleeve 13 is mounted in the second bearing block 4. This is - seen in cross section - U-shaped and has at the end opposite the first bearing block 2 a transverse wall 4a which is provided with a slot for the insertion of the cable 10.
  • the tensioning lever 6 is first pivoted clockwise, so that the sleeve 13 slides out of the bearing block 4 along the surface 4d of the base 4c (see FIG. 3).
  • the two locking tabs 3a, 3b are below the influence of their own elasticity apart. The foot can now be inserted into the ski boot 3.
  • the skier can change the distance to both sides by turning the sleeve 13 by hand. If this is not sufficient, there is the possibility of also adjusting the screw plug 9 in the threaded bore 8a by rotating the cable 10.
  • the variant of a tightening fastener 1 'shown in FIG. 4 is characterized in that two second bearing blocks 4' are present for two parallel cables 10 ', but only a single first bearing block 2' in which a tensioning lever 6 'on one Axis 5 'is supported. This simplifies handling.
  • the tightener closure 1 ′′ shown in FIGS. 5-8 according to a second embodiment is similar to the one dealt with first. It differs from this only in that the cable 10 ′′ is shown with its plastic sheath 11 ′′ (see FIG. 7), and the base 4 ′′ c of the bearing block 4 ′′ on its upper side has a hollow cylindrical surface 4''d is limited, the diameter of which corresponds to the diameter of the sleeve 13 ''.
