Definitions

  • the invention relates to an adjustment system for ski boots with a sleeve that can be pivoted in the direction of travel relative to a shell, the inclination of which can be adjusted by means of a bolt that is fixed in the sleeve and that is height-adjustable in the shell and that can be fixed in its position, the pivoting movement of which at the front can be arranged by a heel Damping spring is damped, which is supported on the one hand on a shoulder of the cuff and on the other hand on a bolt which is height-adjustable and which can be fixed in its position in the shell, the shell-side end of the bolt being adjustable in height in the travel direction by means of a ball joint in a height-adjustable sleeve which is fixable in its position limited pivotally mounted or is itself designed as such a sleeve, or wherein the pivoting movement of the cuff is limited to the rear by an adjustable stop and this stop is adjustable in height in the shell and in its Position fixable sleeve
  • a ski boot is known from EP-A-434 663, in which the pivoting of the cuff relative to the shell is dampened by a damping spring arranged on the heel side and the bolt loaded by the damping spring is height-adjustable in the shell and is fixed in position in its position.
  • the connection of the bolt loaded by the damping spring to the height-adjustable sleeve by means of a ball joint can also be found in this document.
  • at least two detents are provided in the sleeve at an axial distance from one another and at an angular offset from one another, into which a counter-detent which can be actuated from the outside optionally engages.
  • a groove is provided after each rest, into which a Projection of the locking pin serving as a counter-catch also engages when the locking pin is pulled out of the catch.
  • the sleeve To change the rough setting of a larger and smaller template, the sleeve must be rotated in one direction or the other with a coin or a screwdriver-shaped tool, which are inserted into suitable slots in the sleeve. As a result, when the sleeve moves axially, the locking pin comes into the path of a groove leading to another locking hole.
  • a rough adjustment of the template also allows the ski boot according to FR-PS 2 341 283. This is done by pushing and screwing a screw-like part through a tab protruding from the shell and through a bolt connected to the cuff, which for this purpose arranged several above one another Has holes.
  • this construction has the disadvantage that the release of the swiveling movement for walking cannot be carried out in a quick and simple manner, but that several hand movements and tools are required for this.
  • the French in Fig. 3. Variant shown, in which the rough adjustment with a Closure of the ski boot is combined, has the disadvantage that the release for walking is only possible when this one closure of the boot is opened and therefore a secure hold in the boot when walking is not guaranteed.
  • the open closure especially its loosely protruding parts such as buckles, etc., would hinder walking and entail the risk of getting caught.
  • the sleeve has an angular offset to the at least one catch, preferably exactly opposite, a guide element oriented parallel to the axis of the sleeve and extending over an axial length, which cooperates with a counter element provided in the shell, so that at Release of the fixation of the sleeve formed by the detent and counter detent prevents its rotation, but an axial displacement is possible.
  • the sleeve has at least two detents arranged at an axial distance from one another, the connecting lines of which lie parallel to the axis of the sleeve and into which the counter detent optionally engages, the axial length of the Guide element is at least as large as the maximum axial distance of the outer catches. It has been found in practice that it is less important for the skier to have the same template automatically set again after each release for walking ("memory effect"), but that the ski boot comes on quickly and easily Different operating conditions and different positions depending on many parameters between the shell and the cuff can be adapted.
  • a spring element preferably a helical spring, is provided which is located at its upper end on part of the sleeve and at the other end on the shell, preferably the bottom which supports the sleeve-receiving sack bottom, and applies a force acting on the sleeve to the sleeve.
  • the sleeve in the unloaded state of the spring element is advantageously in a position in which a catch, preferably the lowest catch, is exactly in a position suitable for engaging the counter-catch.
  • the catches are designed as openings as in EP-A-434 663, which are arranged at an axial distance from one another and the counter-catch is designed as a spring-loaded locking bolt articulated on an actuating lever, which is loaded with a spring element by a spring element Locking pin is pressed into the opening
  • the invention advantageously provides that the guide element as a groove or slot in the sleeve and the counter element is designed as a guide pin which engages in the groove or the elongated hole and does not hinder the axial displacement. This is a reliable and at the same time uncomplicated and therefore relatively cheap construction.
  • the guide pin can be removed from the groove or the elongated hole perpendicular to the axis of the sleeve is mounted, preferably in a bore of the shell oriented perpendicular to the axis of the sleeve, which can be closed to the outside by a removable closing element.
  • a special protection of the material of the ski boot surrounding the adjustment system by favorable introduction of the forces exerted over a large surface area can be achieved in that, according to a further feature, the guide pin is attached to a guide pin, the guide pin and the locking pin being pushed on in a manner transverse to the sleeve second sleeve are guided.
  • the design variant is the adjustment path of the locking bolt when the locking lever is pivoted out of the locked position into the Unlocking position is equal to the depth at which the locking pin engages in the locking hole, provided that, according to an additional feature, the locking lever can be rotated outside of the locking position about an axis oriented perpendicular to the adjustment path of the locking bolt in a circular bore of the second sleeve and in a 180 ° rotated position can be pivoted back into the locked position, the locking bolt remaining in the unlocked position.
  • 1 shows an axial section of an adjustment system used in the ski boot according to an embodiment of the invention and 2 shows an axial section of an adjustment system used according to a second embodiment.
  • a threaded bolt 3 enclosed by a helical spring 2 is mounted in a heel-side recess of a ski boot consisting of a lower shell and cuff.
  • the helical spring 2 is supported on the one hand on a nut 1 screwed onto the upper end of the threaded bolt 3, by means of which the pretensioning of the spring can be changed to set the desired damping effect.
  • the helical spring 2 is supported on a laterally projecting edge of a sleeve 4, which rests with its lower edge on a plate 5, which rests on a shoulder 21 of the cuff of the ski boot.
  • the upper starting point for the helical spring 2 could equally well be fixed, so that the damping effect is always kept constant.
  • the bolt 3 is fixedly attached to the boot of the ski boot, with the coil spring 2 being omitted.
  • the template would be fixable in a definable position without a damping effect.
  • a ball 13 is provided at the lower end of the threaded bolt 3 and is held in the upper end of a height-adjustable but fixable sleeve 7.
  • the threaded bolt 3 passes through the arc of the sleeve 7 in a bore 17, which gives the bolt 3 a game for limited pivoting movement in the running direction of the ski boot.
  • This variant has the advantage that the force is redirected in the connection area of the threaded bolt 3 and sleeve 7 and no forces acting in the direction of travel on the ski boot are caused, which expand the ski boot in the ankle area and thus impair the hold of the foot in the boot.
  • a one-piece arrangement could also be selected, in which the bolt 3 forms a rigid unit and can be connected to the shell lower end is designed as a sleeve.
  • the sleeve 7 is seated in a transverse bore 18 of a second sleeve 8, which in turn is mounted in a bore 19 in the shell of the ski boot.
  • a locking lever 12 is provided, which is connected in an articulated manner to a locking bolt 16, which engages with a locking pin 24 under the influence of a spring 9 in at least one catch 26 designed as an opening in the sleeve 7.
  • two openings 26 arranged at an axial distance from one another are provided. These are located exactly one above the other in the direction of the axis A of the first sleeve 7, i. H. whose connecting line V is parallel to the axis A.
  • a guide element is provided at an angle to the catches 26, preferably exactly opposite, which is preferably an elongated hole 27 is executed in the sleeve 7.
  • a counter element engages in this elongated hole 27, which is advantageously offset by 180 ° with respect to the latching openings 26, which is advantageously designed as a guide pin 28 likewise guided in the second sleeve 8, which does not have the axial displacement of the sleeve 7 at its end facing the sleeve 7 hindering guide pin 29 is provided. This pin 29 protrudes into the elongated hole 27 and thus prevents rotation.
  • a groove can of course also be provided as a guide element. It would also be conceivable to provide a groove in the shell 20 of the ski boot, in which a projection on the sleeve 7 is guided.
  • the invention is not limited to the described combinations of guide elements and counter elements or to certain arrangements of these elements.
  • the arrangement of the guide and counter element does not necessarily have to be positioned exactly opposite the arrangement of the catch and the catch, but this has the advantage that both arrangements can be mounted in the same sleeve or the same recess or bore in the shell 20 .
  • the axial length of the groove or the elongated hole 27 is at least as large as the maximum axial distance of the outermost notches 26 and is advantageously greater than this in order to allow sufficient pivoting between the cuff and the shell when walking and thus to allow the ankle joint to bend freely.
  • the pivoting to the rear is limited by the abutment of a plate 6 on the upper part of the sleeve 7, this plate 6 between the shoulder 21 of the sleeve, on which the sleeve 4 and the coil spring 2 is supported, and the upper part of the sleeve 7 is provided.
  • the variant shown in Fig. 2 is an example of a case in which the said sleeve 7 is only a stop for the backward pivoting of the sleeve 21, during which the forward pivoting is completely released and of no arrangement cooperating with the shell 20 of the shoe is hindered or dampened. In this case, as shown in FIG.
  • a spring element preferably a helical spring 31, is advantageously provided, which rests with the upper part on a part of the sleeve 7 and with the other end on the Shell 20 of the ski boot is supported.
  • said helical spring 31 is advantageously provided inside the sleeve 7 and is supported on the inside of the upper end of the sleeve 7.
  • the other end is supported on the bottom of the blind bore 32 in the shell 20 that receives the casing 7.
  • the spring is advantageously selected and designed in such a way that the sleeve 7 is in the unloaded state of this spring element 31 in a position in which a catch 26 is exactly in a position suitable for engaging the counter-catch. If, as in the example shown, there are several catches 26, the cheapest variant is that the lowest catch is in said position, ie in the unloaded state, the spring 31 brings the sleeve 7 into the position that protrudes the most from the shell of the ski boot.
  • the storage of the guide pin 28 and the guide pin 29 located thereon, which is also provided in this system, in the second sleeve 8, in which the counter-latch can also be moved, has the advantage of simplified production and further the advantage that the guide pin 29 in this sleeve 8 is slidably and therefore mounted perpendicular to the axis of the sleeve 7 removable from the groove or the elongated hole 27.
  • the guide pin 29 in this sleeve 8 is slidably and therefore mounted perpendicular to the axis of the sleeve 7 removable from the groove or the elongated hole 27.
  • only one bore 19, preferably oriented perpendicular to the axis of the adjustable sleeve 7, can also be provided in the shell 20, in which the guide pin 29 is removably mounted from the elongated hole 27 serving as a guide element.
  • this bore 19 is advantageously closed by a removable closing element (not shown) which, in the closed position, holds the guide pin 29 pressed into the groove or the elongated hole 27.
  • a removable closing element (not shown) which, in the closed position, holds the guide pin 29 pressed into the groove or the elongated hole 27.
  • a shape of the upper part of the locking lever 12 is also shown, in which it is ensured that the lever 12 can be pivoted further over the unlocking position, in which the axis of the sleeve 8 and the longitudinal axis of the lever 12 are substantially parallel and at the same time the counter-catch 24 remains in a position in which it does not engage in one of the catches 26.
