Definitions

  • the invention relates to a ski boot with a shell made of plastic and a shaft or a sleeve which can be pivoted relative to the shell, the end part of which, facing the tip of the shoe, pivots on the shell, in particular a projection thereof, when the tip is pivoted, the shaft or the cuff has at least one recess, groove or opening running transversely to the longitudinal direction of the shoe.
  • a shaft has become known in which the front end region has adjustment elements for the adjustability of the stiffness and bending properties.
  • a bending element was either stretched over the surface of the shell as a tension belt or connected to the shell.
  • additional anchorings on the shell are required, which increase the risk of the shell breaking at the anchorage points.
  • compromises were made with regard to the pivotability of the sleeve in the known embodiment.
  • the adjustment elements formed by sliders had to overlap the slot formed in the cuff on both edges to ensure loss protection.
  • the invention now aims to provide a simple and safe design of the type mentioned, in which any supporting elements can be secured in their respective position and furthermore, a design is created in which an expansion of the cuff with a pivoting into the template with Security is avoided.
  • the invention essentially consists in the fact that carrier elements, in particular rubber-elastic inserts, are inserted into the recess, groove and opening and rigid support elements can be inserted in their position in a fixable manner. Due to the fact that carrier elements, in particular rubber-elastic inserts, are inserted into the recess, groove or opening, it is possible to insert any supporting elements in their respective position in a fixable manner without having to overreach the edges of a slot to a significant extent.
  • the arrangement of carrier elements ensures that the support elements remain in their position even when the sleeve is subjected to deforming forces.
  • the support elements can be anchored in a particularly advantageous manner in such a way that the support elements are connected to the shell at the lateral edges of the recess, groove or opening, whereby the advantage is achieved that the connection of the support elements to the shell simultaneously acts as a tie rod an expansion of the cuff can be used relative to the shell.
  • the design is advantageously made such that the connection of the carrier elements to the shell takes place via at least one head screw or rivet penetrating the cuff or the shaft, the head of which extends over the outside of the cuff or the shaft and the widened foot part of which is an elongated hole the shell overlaps inside.
  • the rigid support elements can be positively connected to the support elements or the rubber-elastic inserts.
  • the pivot axis and the connection points of the carrier elements with the lower shell are different from one another .
  • the long hole is provided in the shell, which voi, - k of the cap screw or rivet is penetrated, whereby preferably is curved, the longitudinal axis of the elongated hole and located on the circumference of a circle having its center in the rotational axis of the shaft or the sleeve lies.
  • Such a design of a curved elongated hole makes it possible to adapt the longitudinal extent of the elongated hole to the permissible pivoting angle of the sleeve or of the shaft relative to the shell, and in this way to limit the pivotability.
  • a widening of the sleeve when the sleeve is pivoted relative to the shell is reliably avoided in that the cap screw or the double-head rivet is designed as a tie rod, which ensures that a predetermined distance is maintained.
  • the rigid support elements advantageously encompass the support element at least partially. Since the support element itself can be held in the recess, opening or groove without any significant pretension, an exact positioning of the support elements can easily be achieved in this way.
  • the support elements can be designed as sliding elements in a manner known per se.
  • the rigid support elements can advantageously overlap the opening, groove or recess on the outside of the shoe. In this way, expansion of the cuff is further counteracted. Reaching behind the inside of the shoe can be avoided so that the displaceability is in no way impaired by the friction properties or the friction of the cuff on the shell.
  • At least one support element is adjustably mounted transversely to the longitudinal direction of the opening, the groove or the recess.
  • the support element is formed by a stop which can be displaced on a threaded spindle and is held in its rotational position, the dimension of which in the longitudinal direction of the spindle is smaller than the clear width of the opening, groove or recess.
  • a threaded spindle can be fixed at the end of a flexible shaft, the other end of which is mounted in a recess in the sleeve and connected to an actuating knurled nut.
  • the support element is advantageously U-shaped, so that the support element can be slidably mounted in the clear cross section of the U.
  • the U-shaped carrier element is advantageously designed as a damping element, in particular made of elastomeric plastic, and at least partially overlaps the supporting elements.
  • All of the above-mentioned support elements can also be used advantageously in a configuration in which the recess is arranged between the end part of the shaft and the projection of the shell, at least one support element being arranged in this area.
  • a separate slot or a recess in the sleeve can be omitted, since the path between the lower edge of the sleeve and the projection of the shell is available as a recess for receiving a support element.
  • the support element is advantageously displaceable and / or adjustable in its effective width.
  • the support element To adjust the effective width of a support element, it is easily possible to choose the cross section of the support element triangular or trapezoidal, the support element with a triangular tip or the narrow side parallel to the base of the trapezoid immersing the recess, groove or opening in the slot and adjustable in the height direction or in the direction of the depth of the slot, in particular against the slot, the groove, the recess or the opening can be tensioned.
  • Another possibility of adjusting the effective width of the support element is to design it as an expandable toggle lever, the design preferably being such that the support element is designed as a spring leaf that can be tensioned by a spindle.
  • the spring leaf When the spindle is rotated, the spring leaf is tensioned or relaxed, the effective width being increased when the spring leaf is tensioned, and when the spring leaf is relaxed, the support elements in the direction of the available path, i.e. the width of the slot, the groove, the gap or the recess becomes smaller.
  • the design can also be such that the support element is designed as an element with a rectangular cross section.
  • Such an element with a rectangular cross section basically has two different sides and can therefore be inserted either with the narrow side or the broad side in order to achieve different widths.
  • the element with a rectangular cross section can advantageously be pivoted about its axis and pivoted about a further parallel axis in both rotational positions in the slot, the recess, the groove or the opening.

  • the shell of a ski boot is designated by 1.
  • a sleeve 3 is articulated on this shell about a pivot axis 2.
  • a foldable rear spoiler 4 is indicated schematically, which can also be articulated about the pivot axis 2.
  • the shell 1 has a shoulder 5, which serves as a stop for the lower edge 6 of the sleeve 3.
  • the lower edge 6 of the cuff 3 can come into operative connection with the counter stop 5, as a result of which the template is limited.
  • a slot 8 is provided in the lower region of the cuff, in which a support element 9 for support elements 10 is arranged.
  • the support elements 10 can be moved in the longitudinal direction of the carrier element 9 and fixed in the respective position, so that the flexion properties of the cuff can be set within wide limits.
  • the carrier element 9 is connected to the shell 1 via a fastening rivet 11. The type of connection is shown more clearly in FIG. 2.
  • the rivet 11 is designed as a double-head rivet and engages behind the inner wall of the shell 1, an elongated hole 12 being formed in the shell 1.
  • the longitudinal extent of this elongated hole 12 can follow a curved path, as is shown in FIG. 1, the curvature essentially corresponding to the swivel radius with the swivel center of the axis 2.
  • the double-head rivet 11 is also designed as a tie rod and the mutually facing inner sides are arranged at a distance a from one another which is insignificantly greater than the thickness b of the shell 1 or c of the sleeve 3. In this way, the shell is widened at one Deformation of the slot 8 prevented at this point.
  • the carrier element 9 is designed as a rubber-elastic band and provided with recesses into which wedges 13 can be inserted according to FIG. 4.
  • the corresponding positions are predetermined on the cuff 3 by grooves 14, whereby depending on the position of the wedges 13, which are designed as relatively dimensionally stable rigid support elements, a more or less rigid flexion behavior of the cuff 3 is achieved.
  • the carrier element 9 has openings 15 into which rigid support elements 16 and 17 according to FIGS. 6 and 7 can be inserted.
  • the rigid support elements 16, like the rigid support elements 17, can be designed with different hardness, so that different stiffnesses or a different bending behavior of the sleeve 2 is achieved by exchanging individual ones of these elements.
  • a cap screw 18 is shown, as it can be used in a simple manner for fixing the support element 9 in order to facilitate the exchange of the elements.
  • Such a double-head screw 18 replaces the double-head rivet 11 of FIG. 2 and facilitates the interchangeability of the carrier element together with the rigid support elements.
  • a support element which has a lateral insertion opening for a rigid support element 19.
  • a rigid support element 19 is shown enlarged in FIG. 10, the elastically deformable head 20 of this element securing the insertion position in the recess of the carrier element 9.
  • FIGS. 11, 12 and 13 An embodiment analogous to that of FIGS. 9 and 10 is illustrated in FIGS. 11, 12 and 13.
  • a support part 22 which is different in hardness and / or thickness is inserted into the carrier element 9, which has an essentially rectangular tunnel cross section 21.
  • rigid support elements 23 are integrally connected to the support element 9, wherein depending on the number of the respective rigid support elements 23 in the central cross-sectional area of the support element 9 different flexion properties can be achieved.
  • the entire support element is exchanged in order to achieve different hardnesses or different bending elasticity, whereas in the previous embodiments it is sufficient to replace the rigid support elements or to move them to another position.
  • FIG. 16 shows a longitudinal section through a front part of the cuff.
  • a recess 25 is provided in the front end area, in which a U-shaped support element 26 is inserted.
  • a support element 27 is slidably mounted transversely to the longitudinal extent of the groove 25, the respective displacement position being predetermined by a spindle 28.
  • the spindle 28 is connected via a flexible shaft 29 to a knurled nut 30, via which the support element 27 can be adjusted.
  • the carrier element 32 contains the support element 33, which can be inserted upright or transversely from the bottom into the carrier element 32 in different rotational positions.
  • the support element 33 has an essentially rectangular cross section.
  • the carrier element 32 is in turn fixed via an axis guided in an elongated hole, for which purpose a screw bolt 34 and a nut 35 having a sleeve are provided for fixing.
  • the support element 33 which is essentially rectangular in cross section, is pivotably articulated on the collar via a bracket 36 and, as can be seen from FIG. 21, is rotatable about its longitudinal axis. Depending on the selected rotational position, the narrow or the long edge of the support element 33 comes into effect, as a result of which the support properties can be changed.
  • a support element 37 is obtained in a carrier element 39 so as to be pivotable about an axis 38.
  • the support element 37 can be folded up or down, which results in a different support characteristic.
  • a trapezoidal tension member 40 is provided, which can be moved into or out of a slot, opening or groove by means of a tensioning buckle 41, the narrower side 42 of the support element 40 being directed inwards .
  • the adjustment thus corresponds to a raising or lowering of this narrower edge 42 in the sense of the double arrow 43, which likewise adjusts the effective width of the support element, since the side edges of the trapezoid diverge outwards.
  • All of the above-mentioned support elements can be arranged in a manner not shown in the drawing without further ado in the slot or gap between the lower edge of the sleeve 3, which was designated 6 in FIG. 1, and the projection 5 of the shell 1, which likewise results in a Changes in damping and flexion properties can be achieved.
