Definitions

  • the invention relates to a ski boot according to the first part of claim 1.
  • a ski boot is described in WO 89/04615, in which a spring forming a damping device acts on the tailgate and its pretension can be adjusted (see FIG. 10).
  • this damping device is coupled to a locking device which consists of a bolt which can be displaced against the force of the spring by means of an eccentric lever and a hole in a housing part. If the skier wants to get into the ski boot with his foot, the eccentric lever is pivoted so that it pulls the bolt out of the hole. Then the tailgate can be swiveled at will.
  • this ski boot is complicated in its construction and therefore also expensive to manufacture.
  • the invention has for its object to eliminate the disadvantages of the known designs and to provide a ski boot that is relatively simple in construction and in which the presentation of the skier can be controlled by a damping device without using a separate locking device.
  • this object is achieved according to the invention by the features of the characterizing part of this claim.
  • the setting option of the damping spring is expanded by the measure of claim 2.
  • the solution according to claim 3 has the advantage of a sensitive adjustment of the height of said axis.
  • the U-shaped bracket could be held in place by frictional engagement on the rear wall of the foot shell. However, this could lead to a loosening of the tailgate axis while driving. By the subject of claim 4, however, the axis of the tailgate is reliably held even when shaken.
  • the solution according to claim 5 is simpler in structure in that the rear wall of the foot shell does not have to be provided with teeth here.
  • the embodiment according to claim 6 has the advantage of a one-piece production of tailgate and U-shaped support part.
  • the subject of claim 7 makes the use of a screwdriver for adjusting the height of the axis of the tailgate superfluous.
  • the measure of claim 8 also aims in this direction.
  • the features of claim 9 ensure that the helical compression spring can be adjusted in its bias. This makes it easy to adapt the spring pressure to the physique of the user.
  • claim 10 limits the pivoting angle of the tailgate to both sides.
  • the measure of claim 11 allows an easy adjustment of the spring preload.
  • the features of claim 12 also aim in this direction.
  • FIG. 1 shows the ski boot in a vertical longitudinal central section in the normal position, FIG. 2 in the entry position and FIG. 3 in a position in which the lower leg of the skier is inclined forward.
  • Fig.1 a is a section along the line la-la in Fig.1 on a larger scale.
  • 4 shows a detail of the ski boot in the normal position on a larger scale in section.
  • Fig.5 shows a similar Chen cut with the temple open.
  • 6 shows a variant of FIGS. 1 to 5 in a partially sectioned side view.
  • Fig. 6a is an associated detail on a larger scale.
  • 7 shows another variant of a ski boot according to the invention in a partially sectioned side view, and FIG. 7a shows a detail of the variant in the diagram.
  • the ski boot shown in FIGS. 1 to 5 is designated as a whole by 10. It has a sole 10a and a foot shell 11 which is integral therewith and which parts are made of plastic or of a rubber-like material.
  • the foot shell 11 carries on each side wall 11b, 11c c a rivet 12, which rents 12 form the pivot axis for the two pivot parts 13 and for a sleeve 14, which is only indicated in FIG.
  • the two rents 12 are located in the area of the skier's ankle.
  • a slot 11 d running in the vertical direction, in which an adjusting bolt 15 is guided.
  • the area of the rear wall 11 located at the elongated hole 11 is provided on the outside thereof with transverse teeth 11 which are triangular in cross section.
  • the adjusting bolt 15 passes through bores in the legs 16a of a U-shaped bracket 16 in side view, which is pushed over the rear wall 11 and whose outer leg likewise carries a row of teeth 16b on its inside, the teeth of which are in the form of an equilateral triangle with the teeth 11 in Intervention can be brought.
  • a spring abutment 18a is attached to the rear of the tailgate 18.
  • the web 13a of the U-shaped pivot part 13 is made of a flexible material and carries a housing 23 which has the shape of a parallelepiped, which is open towards the tailgate 18 and bears against it.
  • the two side walls 23a of the housing 23 have in their upper half elongated holes 23b, in which the two projecting ends of a bolt 19 are guided, which is supported with its central region in the abutment 18a of the tailgate 18.
  • the two lower halves of the side walls 23a of the housing 23 carry aligned bores 23c in which a shaft 20 is mounted, on which a cam 21 is attached eccentrically. Viewed in the direction of the axis of the shaft 20, this has approximately the shape of an equilateral triangle with rounded corners.
  • a helical compression spring 22 is mounted between the cam 21 and the spring abutment 18a.
  • the cam 21 serves to be able to adjust the pretension of the spring 22 to three different values according to the wishes of the user.
  • the end of the shaft 20 protruding from the housing 23 is provided with an actuating member, e.g. provided with a slot 20a for a screwdriver or with a hand lever, not shown.
  • the helical compression spring 22 is somewhat pretensioned, and the bolt 19 is located approximately in its central position opposite the two ends of the elongated holes 23b.
  • the rear of the tailgate 18 includes a basic angle a between 6 and 12 with a vertical plane on the top of the ski.
  • the pivot part 13 is also in its central position.
  • the pivoting part 13 is pivoted downwards and the tailgate 18 is pivoted to the left (see FIG. 2).
  • the two rivets 12 form the pivot axis for the pivot part 13 and for the sleeve 14, and the tailgate 18 is rotated about the pivot axis 17 until its back includes an entry angle ⁇ with a vertical plane on the top of the ski, which is up to 20 ° from the Vertical plane lies to the rear and which lies opposite the angle a with respect to the vertical plane.
  • the helical compression spring 22 rests only with the lower end of the cams 21, whereas the upper end is at a distance from the spring abutment 18a.
  • the tailgate 18 can assume the position shown in FIG. 3 while driving.
  • the back of the tailgate 18 is inclined forward by a variable angle 5 between 6 and 16 °.
  • the bolt 19 bears against the lower ends of the two elongated holes 23b in the housing 23 and thereby compresses the helical compression spring 22 until their turns lie hand-to-hand.
  • the pivot part 13 was pivoted slightly upwards.
  • the adjusting bolt 15 is first loosened. As a result, the U-shaped bracket 16, the legs 16a of which spring slightly outwards, is pivoted upwards or downwards. Subsequently, as soon as the selected position of the pivot axis 17 is reached, the adjusting bolt 15 is tightened again. As a result, the template angle s of the ski boot 10 is changed without the spring preload being influenced thereby.
  • ski boot 10 shown in the drawing has an inner boot that is only indicated by dash-dotted lines.
  • the ski boot 10 ' differs from the one described first in that on the foot shell 11' below the rivets 12 and offset to the rear thereof, a U-shaped support part 24 'is articulated by means of rivets 25'.
  • the web 24'a of this support part 24 ' is - seen in cross section - curved according to an arc that corresponds to the curvature of the rear wall 11'a of the foot shell 11'.
  • the web 24'a is connected via a type of bead 24'b to the tailgate 18 'of the ski boot 10' in the manner of a joint.
  • a plurality of superimposed grooves 11'f which are semicircular in cross section are recessed.
  • the web 24'a of the support part 24 ' has on its inside a groove 24'c which is semicircular in cross section. If the grooves 24'b and 11'f, viewed in cross section, complement each other to form a circle, a cylindrical pin 26 can be inserted, through which the position of the support part 24 'relative to the foot shell 11' and thus the height of the tailgate 18 'is set.
  • FIGS. 7 and 7a The embodiment of a ski boot 10 "shown in FIGS. 7 and 7a is similar to that described above. It differs from this only in that the support part 24" is mounted on the same axis 12 "as the swivel part 13 ', and in that the Tailgate 18 "is articulated by means of a hinge 27" at the upper end of the web 24 "a.
  • an adjusting screw could be used to adjust the helical compression spring, which is secured in the selected position by a lock nut.
