Definitions

  • the invention relates to a damping element for ski boots with a sleeve which can be pivoted in the direction of travel relative to a shell, the pivoting movement of which is damped by a damping spring arranged on the heel side, which is supported on the one hand on a shoulder of the sleeve and on the other hand on a bolt mounted in the shell.
  • the object of the invention is to provide measures by which these disadvantages are eliminated.
  • the bolt loaded by the damping spring is vertically adjustable in the shell and can be fixed in its position.
  • the bolt loaded by the damping spring is pivotally supported at its shell-side end by means of a ball joint in a sleeve in the direction of travel, the sleeve being guided in an adjustable manner in the shell.
  • the sleeve is provided with at least two detents which are arranged at an axial distance from one another and offset at an angle to one another and into which a counter-detent which can be actuated from outside engages.
  • the catches are designed as openings, holes or the like, which are arranged at a height and at an angular distance from one another, wherein the counter detent is designed as a spring-loaded locking bolt articulated on an actuating lever, which is pressed under the load by the damping spring with a locking pin into the openings, holes or the like.
  • each of the openings, holes or the like serving as a rest is to be connected.
  • a groove is provided on the outer surface of the sleeve, into which a projection of the locking pin, which serves as a counter-catch, engages when it is pulled out of the catch.
  • the locking bolt is advantageously guided in a sleeve which is pushed across the sleeve for the mounting of the bolt loaded by the damping spring.
  • the locking bolt has a collar guided in the transverse sleeve, on the outside of which the pin engaging in the catch is provided.
  • FIG. 1 shows an axial longitudinal section of a damping element inserted into the ski boot along the line I-I of FIG. 2, and FIG. 2 shows a section along the line II-II of FIG. 1.
  • a threaded bolt 3 which is enclosed by a helical spring 2 is mounted on the its lower end carries a ball 13 which is held in the upper end of a height-adjustable and rotatable sleeve 7 in the shell 20.
  • the threaded bolt 3 passes through the bottom of the sleeve 7 in a bore 17, which gives the bolt 3 a game for a limited pivoting movement in the running direction of the ski boot.
  • the helical spring is supported on the one hand by a nut 1 screwed onto the upper end of the threaded bolt 3, which is provided with a sleeve 14 engaging in the helical spring 2.
  • the helical spring 2 is supported on a laterally projecting edge 15 of a sleeve 4 which engages in the lower end of the helical spring and forms a stop for the sleeve 14.
  • the sleeve 4 sits with its lower edge 15 on a plate 5, which rests on a shoulder 22 of the sleeve 21.
  • the sleeve 7 sits in a transverse bore 18 of a sleeve 8, which in turn is mounted in a recess 19 of the shell 20 and carries a locking bolt 16 which is guided with a collar 11 in the sleeve 8 and at its end projecting from the sleeve 8 by means of a pivot pin 10 is mounted in an operating lever 12.
  • the collar 11 At its end facing the sleeve 7, the collar 11 is provided with a locking pin 24 which engages under the influence of a spring 9 in a locking hole 26 of the sleeve 7.
  • the sleeve 7 has a plurality of, in the present case three, locking holes 26 which are arranged at different heights at an angle to one another.
  • leading grooves 27 are provided in the center, which are recessed on the outside of the sleeve 7.
  • the spring 9 is supported on the one hand on the collar 11 and on the other hand on the bottom 25 of the sleeve 8, in which a bore 37 is provided for the passage of the locking bolt 16.
  • the locking lever 12 In order to pull the locking pin 23 out of the detent 26 when pivoting the lever 12 into the horizontal position out of the detent hole 26, without the projection 24 leaving the groove 27, the locking lever 12 is designed such that the displacement of the locking bolt 16 when pivoting the locking lever 12 from the locked position into the unlocking position is equal to the depth into which the locking pin 23 engages in the locking hole 26 .
  • the path of the locking bolt 16 by the height of the projection 24 should be greater than when pivoting of the locking lever 12 from the locking position to the open position.
  • the distance --a-- between the hinge pin 10 and the upper surface of the lever 12 can be such that the distance --a-- minus the distance --b-- between the hinge pin 10 and the bottom 25 of the sleeve 8, on which the lever is supported, is equal to the depth --c-- in which the locking pin 23 engages in the locking hole 26.
  • the projection 24 In order to be able to turn the sleeve 7, the projection 24 must also emerge from the groove 27, as will be described in more detail later.
  • the distance from the corner 34 of the lever 12 to the pivot pin 10 is greater than the distance --a--, etc. by at least the height of the projection 24.
  • the same longitudinal slots 28 are provided at the upper end, the number of which preferably corresponds to the number of locking holes 26 and are expediently arranged at the same angular intervals as the locking holes from one another.
  • the sleeve 7 is supported at its upper end on a plate 6 located at the bottom of a recess 31 of the sleeve 21, the seat being rounded, so that a slight angular adjustment between the plate 6 and sleeve 7 is possible when the sleeve 21 is pivoted in the running direction is, whereby a bending stress on the threaded bolt 3 is avoided. If such a bending stress can be accepted, it is possible to design the threaded bolt 3 and the sleeve 7 as a one-piece body.
  • the sleeve 7 is guided with play in a vertical bore 29 of the shell 20 and rotatably mounted in the bore 18 of the sleeve 8, which is inserted into a transverse bore 30 of the shell 20.
  • the threaded bolt 3 is provided with a flattened portion 32 which is seated in a corresponding opening 39 in the plate 5, as a result of which the threaded bolt 3 is secured against rotation.
  • the nut 1 can be adjusted by means of a screwdriver, a coin or the like. be carried out, which or which can be inserted through a window 35 in the wall of the sleeve 21 in slots 36 of the nut 1.
  • the window 35 is covered by a cap, preferably not shown, which can be folded upwards.
  • the damping element according to the invention acts in the following way: In the position of the damping element shown, the locking pin 23 engages in the central locking hole 26, so that a medium template for skiing is set. If the skier wants to go comfortably with the ski boot, he pivots the lever 12 into the horizontal position, whereby the locking pin 23 emerges from the locking hole 26, so that the sleeve can pivot freely about its pivot axis and takes the sleeve 7 with it.
  • the projection 24 engages in the groove 27, the upward movement of the sleeve being limited by the length of the groove 27, while the pivoting movement in the other direction is limited by the length of the groove or by the distance --e-- of the sleeve 21 from the shell 20 is limited. If the skier wants to snap in the original position, he pivots the lever 12 back into the position shown and moves the foot until the locking pin 23 snaps back into the central locking hole 26 under the influence of the spring 9. By guiding the projection 24 in the groove 27, an unwanted rotation of the sleeve 7 is prevented.
  • the skier wants to set a larger or smaller template, he rotates the sleeve 7 with a coin or a screwdriver-shaped tool, which he or she inserts in the slot 28 opposite it, in one direction or the other, so that the locking pin 23 during an axial movement the sleeve 7 comes to lie in the path of the higher or lower locking hole 26.
  • the lever 12 is moved into an oblique central position in which the corner 34 is supported on the bottom of the sleeve 8, as a result of which the projection 24 emerges from the groove 27.
  • the distance of this corner from the hinge pin 10 is at least larger by the height of the projection 24 than the distance --a--.
  • the nut 1 is screwed onto the thread of the threaded bolt 3 until the sleeve 14 strikes the sleeve 4.
