Definitions

  • the invention relates to a ski boot with a shell and a shaft part pivotable relative to this shell, in particular a sleeve, in which a resilient and / or damping support member is provided for damping the pivoting movement of the shaft part relative to the shell.
  • the invention now aims to enable the pivoting movement of a cuff or a shaft relative to a shell to be supported in such a way that no forces that expand the shell or the cuff occur, and further aims to provide the support to keep these components as small as possible.
  • the invention consists essentially in that the support member is formed by a two-armed lever, the pivot axis of which is articulated via a link to the shell, that at least one arm of the two-armed lever acts resiliently on the shaft part and that the other arm on the shaft part supported or slidably supported on the shell.
  • an adjustable and adjustable stop can be provided according to a preferred embodiment of the ski boot according to the invention, which limits the pivoting path of the shaft part relative to the shell at least in the direction of a reserve.
  • the desired template can be set by such a stop and the resilient support of the swiveling forces takes place only from this minimal template in the direction of a further template and thus pivoting of the shaft part or the cuff to the front.
  • This additional adjustable stop can be realized in a simple and space-saving manner in that the adjustable stop or a counter stop is connected to a shell-side bearing part of the pivot axis of the handlebar and is preferably formed in one piece with it. In this way, the bearing part itself can be used as part of the stop or counter-stop.
  • the resilient support of the pivoting forces is preferably carried out by arranging at least one compression spring, the design preferably being such that the two-armed lever is pivotably articulated on one, preferably its upper, free end on the shaft part or the sleeve and on its other end with interposition at least one compression spring is supported on the shaft part or the sleeve.
  • the spring force of the compression spring can be adjusted depending on the requirements adjust, whereby the desired, more or less hard, resilient limitation of the swivel path is achieved.
  • the shaft part has a compression spring with adjustable spring preload on both sides of the longitudinal center plane, the two-armed lever being supported on both compression springs.
  • the compression springs can be accommodated in recesses in the shaft part or the sleeve, in particular in blind bores, and supported on the bottom thereof. In this way, the compression springs, which can be designed in a simple manner as helical springs, are easily accessible from the outside and, if necessary, can easily be replaced by springs with a different spring characteristic.
  • the pivot axis of the handlebar or the bearing part thereof is fixed on the shell so as to be adjustable relative to the longitudinal center plane of the shell. This measure allows the kinematics of the pivoting of the shaft part to be changed relative to the shell or to the sole plane and it is possible to impart a different inclination to the longitudinal center plane of the shoe to the shaft.
  • the design can be made in a known manner so that the turns of the coil spring have different slopes, so that after a first part of the turns is applied, a progressive spring characteristic is achieved.
  • it is advantageous to make the training so that the handlebar is articulated on the shell and arr two-armed lever so that it is in the basic position of the pivot position of the shaft part in is substantially normal to the longitudinal axis of the two-armed lever.
  • the shaft part or the sleeve can be pivoted into the upright position beyond the originally limited pivoting position, only the restoring forces of the spring having to be overcome, since compression of the compression spring also occurs in this area when the linkage the handlebar was chosen so that it is in the basic position of the pivot position of the shaft part substantially normal to the longitudinal axis of the two-armed lever, since this basic position essentially corresponds to the minimum template specified by the adjustable stop.
  • the components provided for the mounting of the handlebar can be protected in a simple manner in that the bearing part of the handlebar on the shell into a recess or opening in the shaft part or the sleeve immersed. In the event of an opening, this can essentially be covered by the two-armed lever itself. However, a separate cover part can easily be provided on the outside of the opening.
  • FIG. 1 is a view of the rear part of a ski boot, partly in section
  • Fig. 2 is an enlarged view of the resilient support device attached in this rear part in the normal position
  • Fig. 3 shows the design of Fig. 2 in a forward pivoted position of the cuff or the shaft
  • FIG. 4 shows the design according to FIG. 2 in a position which enables upright walking
  • FIG. 5 shows a section through a cuff that runs essentially parallel to the sole
  • FIG. 6 shows a view in the direction of arrow 6 of FIG 5
  • FIG. 7 a modified embodiment of the resilient support in a representation analogous to FIG. 2
  • FIG. 8 an enlarged detail from FIG. 7.
  • Fig. 1 the shell of a ski boot 1 is designated 2.
  • a cuff 4 is provided which is pivotable about a pivot axis 3, the pivotability of which around the axis 3 facilitates an angling of the leg with respect to the sole plane 5.
  • the cuff 4 has an opening 6 in its rear area, which can be locked by a cover 7.
  • a sleeve 8 is provided which receives a coil spring 9.
  • the shell 2 carries a bearing block 10 for a pivotably mounted link 11, at the free end of which a two-armed lever 13 is pivoted about an axis 12.
  • the two-armed pivotable lever 13 cooperates with the compression spring 9 via its one lever arm 14.
  • the second lever arm 15 is slidably supported on the outside of the shell in the vertical direction in this embodiment.
  • the pivot axis 12 of the two-armed lever 13 runs essentially parallel to the bearing axis 16 on the shell 2.
  • the reference numerals for identical components have been retained.
  • the upper end 15 of the two-armed lever 13 is pivoted about an axis 19 on the shaft part 4.
  • the articulation point thus forms a fixed support point with respect to the shaft part 4, the function remaining the same for the rest.
  • the link 11 moves upward in the direction of the arrow 17, which denotes the pivoting direction of the shaft into the original position.
  • the bias of the spring is adjustable by an adjusting screw 20.
  • the spring 9 can be influenced in its pretension, for which purpose an axially displaceable pressure plate 21 is connected to the set screw, for example by a thread.
  • the maximum reserve position is predetermined by the shell-side stop 22, which collides with the lower edge 23 of the cuff when pivoting against the direction of the arrow 17.
  • Fig. 2 shows the normal position, whereas in the representation according to Fig. 3 the maximum template is shown. Ir. this maximum template position, the handlebar 11 is up. pivoted and the spring 9 compared to its state in Fig. 2 compressed. The swivel path into the original position is thus taken up over a relatively short spring travel of the spring 9, with essentially only tensile forces acting in the direction of arrow 24 on the shell itself, which do not result in widening of the shell in the ankle area. The remaining support forces are absorbed exclusively by the material of the sleeve or the shaft part 4.
  • the pivot axis 16 of the handlebar 11 can be released from its mounting 10. This is shown in Fig. 4, wherein after releasing the pivot axis 16 of the We g of the cuff 4 is released up to the stop 22 on the shell or lower shell. With this design, no resilient restoring forces act on the cuff or the shaft part in this notched position of the handlebar 11.
  • 5 shows a section through the axis plane of two helical springs 9 arranged on both sides of the longitudinal center plane 25 of a shaft.
  • the two-armed lever 13 has at its connection point to the springs 9 laterally projecting rims 26 which carry the set screws 20 for the adjustment of the spring preload.
  • 5 is shown in a perspective view from behind in the direction of arrow VI in FIG. 5.
  • 6 also shows an embodiment of the end cap 7 for the opening in the sleeve 4.
  • a modified bearing part 27 for the pivot axis 16 of the handlebar 11 is provided on the shell 2.
  • This bearing part 27 has in addition to the Bearing point for the pivot axis 16 an outwardly projecting stop part 28 for limiting the pivoting of the shaft part or the sleeve 4 down.
  • the two-armed lever 13 is in turn pivotally connected to the shaft part and is supported at its lower end against a compression spring 9, the spring preload of which is adjustable by means of the adjusting screw 2 (; and the pressure piece 21.
  • the sleeve 4 carries one in its longitudinally adjustable stop member 29 which is articulated about an axis 30 pivoted to the sleeve or the shaft portion 4. in the g in Fi.
  • the handlebar 11 is now pivoted in the same direction as the pivoting of the shaft part 4 and in this way a corresponding pressure is introduced into the spring 9.
  • the adjustable stop 29 can be pivoted out of its position limiting the adjustment path by actuating a rocker 31, this adjustable stop 29 being pivoted outwards about the axis 30.
  • the rocker 31 can be adjusted by using the stick end 32 on the recess provided for this purpose, the rocker 31 being supported on a nose 37 and in this way introducing the required pivoting torque into the adjustable stop 29.
  • the length adjustability of the adjustable stop 29 is shown enlarged in FIG. 8. Swiveling about the axis 30 is a bolt 33 which carries a bolt thread.
  • the cooperating with the outwardly projecting part 28 of the bearing part 27 lower part 34 of the adjustable stop 29 carries a nut thread which is screwed more or less far onto the bolt thread of the bolt 33 by actuation of a knurled nut.
  • the knurled nut is designated 35 here.
  • the rocker 31 is pivoted about an axis 36 on the lower part 34 of the stop and, by using the stick, the end of which is designated 32, the lower part 34 of the adjustable part is pivoted due to the counter stop (nose 37) which is stationary relative to the cuff Stop in the direction of arrow 36, whereby the lower end of the adjustable stop 34 comes out of collision with the stop 28 which is stationary with respect to the shell 2 and the pivoting of the sleeve or of the shaft part 4 downward is released.
