Definitions

  • the invention relates to a ski boot with a shell and a shaft or a cuff pivotably articulated on the shell, in which shell and shaft or cuff are connected to one another in the heel region via a spring element and a tension member acting on the spring element is pivotably attached to the shell is, the tension member passes through an abutment for the spring fixed on the shaft or on the sleeve and engages on the end of the spring facing away from the abutment.
  • the tension member is designed as a rod and is pivotably articulated on the shell.
  • the bearing point or the abutment on the pivotable shaft or the pivotable sleeve can be formed as an extension formed in one piece with the shaft or the sleeve, which leaves a groove or recess running in the longitudinal direction or in the direction of the Achilles tendon for the passage of the pull rod.
  • the spring assembly arranged above this extension or abutment is supported on the one hand on this extension and is overlapped by the tension member at the free end of the tension member. At this point, the spring preload can be changed by shortening the tension member, for example by arranging a nut.
  • an adjustable support in the form of a stop for the Limitation of the maximum reserve is provided, depending on the setting position of the maximum reserve, this stop also hits the abutment on the shaft or on the cuff in different angular positions, so that this abutment on the shaft or on the cuff depending on the selected settings or after the occurring swivel angle between the shell and the shaft must absorb eccentric, eccentric forces, which represent a high material stress on the abutment.
  • the invention now aims to provide an embodiment of the type mentioned at the outset, with which it is possible to make even spring pacts with high spring force with small components, and in particular without undue overloading of plastic bearing blocks formed integrally with the shaft or the pivotable sleeve To accommodate space with a small throat and to be able to absorb correspondingly high support forces without excessive overloading of the abutment points, without these components having to be enlarged.
  • the invention essentially consists in that the abutment on the shaft or the sleeve is pivotally mounted on the shaft or the sleeve about an axis crossing or cutting axis.
  • a second pivotable bearing point is provided at the location of the abutment on the pivotable sleeve or the pivotable shaft, starting from a training as was assumed in the preamble, a second is at a relatively short distance from the pivotable bearing point on the shell swiveling Arranged bearing point, the distance from the first bearing point on the shell can be significantly less than the entire length of the tension member and the spring assembly. Due to this reduced distance, it is possible to keep the projection over the rear end of the shoe less and thereby enable the attachment of a spring assembly in such a way that the entire components of such a resilient damping into the shell and the rear wall area of the cuff or of the shaft can be integrated.
  • the two articulation points of the damper on the shell and the shaft are each arranged near the free ends of the entire length of such a shock absorber and are therefore one relatively large distance between the rear edge of the shoe and the damper component must be maintained, the second pivotable bearing, which is traversed by the tension member, to make the training so that the distance can be chosen much smaller and the outreach to the rear is significantly reduced.
  • this abutment which can simultaneously represent the spring plate for the compression spring and possibly a counterstop for a limit stop to limit the pivoting of the shaft or the cuff into the return position, is pivotably arranged, the eccentric forces are significantly reduced and it becomes ensures that both the spring and any limit stop provided for limiting the pivoting of the shaft or sleeve into the return position always take effect in the axial direction of the tension member and thus become effective over the entire area of the respective counter-stop or spring plate without tilting.
  • the training according to the invention is preferably made such that the abutment is designed as an annular disk is which is traversed by the tension member, and is pivotally mounted on diametrically opposite pins or recesses in recesses or on pins of a bearing block fixed on the shaft or the sleeve.
  • a small, stable component is proposed, which can also be securely anchored in bearing block components which are also of small construction and which are integrally formed, for example, with the material of the shaft or the sleeve, and which have the corresponding strength properties in order to reliably absorb the respective supporting forces.
  • This abutment which is designed as an annular disk, additionally allows a certain possibility of compensation in the case of lateral pivoting of the shaft or the sleeve by axial displacement of the respective bearing journal in the corresponding recesses, so that in these cases too, no unacceptable, eccentric forces on the Abutments are exercised.
  • the pins or the associated recesses have a certain amount of play, since the respective spring forces or the forces which occur in the event of a collision with the limit stop for limiting the reserve are always flat from the Washer can be included.
  • the design according to the invention is advantageously made such that the abutment can be put into operative connection directly with a stop fixed on the tension member for limiting the reserve.
  • a structurally extremely simple and small component can be used as a limit stop for the pivoting of the shaft or the cuff into the reserve, which in the simplest case can be formed by a knurled nut.
  • the tension member In the case of the arrangement of such a limit stop for the pivoting of the shaft or the cuff in the In the reserve position, the tension member must be designed as a rigid rod, at least in that section, which bears the stop for the reserve limit.
  • the design according to the invention is advantageously made such that the entire tension member is designed as a rigid rod.
  • the design can be such that the stop for the limitation of the height can be fixed on the rod in an adjustable manner.
  • FIG. 1 shows a ski boot with a spring member articulated according to the invention in the heel or Achilles tendon area
  • 2 shows an enlarged, schematic representation of the articulation kinematics, as it results from the use of a second, pivotable articulation of such a spring element
  • FIG. 3 shows a schematic representation of the conventional solutions for explaining the eccentric forces occurring here.
  • 1 denotes a ski boot, in which a shaft or a cuff 3 is articulated on a shell 2 so that it can pivot about an axis 4.
  • locking members 5 are indicated on the shaft.
  • a resilient component 6 is provided in the heel area for connecting the shell 2 to the pivotable shaft or the pivotable sleeve 3, which has a tension member 8 which is pivotally attached to the shell 2 about an axis 7.
  • An abutment 10 is fixed on the pivotable shaft or the pivotable sleeve 3 so as to be pivotable about an axis 9.
  • This abutment 10 is traversed by the tension member 8, the tension member 8 carrying a height-adjustable limit stop for limiting the pivoting of the pivotable shaft or the sleeve 3 into the return position.
  • This stop 11 acts in maximum permissible reserve position together with the abutment 10.
  • the abutment 10 also serves as a spring plate for a spring 12, the spring force of which is adjustable by means of a knurled nut 13.
  • the articulation axis of the tension member 8 formed by a rod on the shell 2 is again designated 7.
  • the pull rod 8 carries a limit stop 11 designed as a knurled nut for limiting the swivel path into the reserve.
  • the abutment component 10 is designed as a circular disk, as is indicated schematically by dashed lines, and is supported on the pivotable shaft or the pivotable sleeve 3 about the pivot axis 9, shown in an enlarged manner, about pivot 21, this pivot axis 9 intersecting the longitudinal axis of the tension member 8.
  • a further pivotability about a third axis can be permitted either by appropriate play in the bearing in the bearing block 22 of the sleeve or the shaft, so that a type of gimbal suspension is provided at this point is possible.
  • Such additional pivotability as can be achieved, for example, by the bearing play in the bearing block, also allows additional forces to be kept away from the bearing block, which would be due to lateral pivoting of the shaft, in particular to corresponding canting adjustments of the shaft.
  • the maximum reserve position as given by the setting of the knurled nut 11, is indicated.
  • the stop formed by the knurled nut 11 cooperates flat with the abutment 10.
  • the abutment 10 can be relative due to the pivotability about the axis 9 Maintain the angular position to the axis of the tension member 8, so that in the position shown on the left in FIG. 2, a spring indicated schematically with 12 in turn cooperates exactly axially with the abutment without side forces.
  • this stop 11 can only engage with its edge 19 on the abutment 15, a wedge-shaped tapering gap forming between the corresponding surface 17 of the abutment 15 and the stop 11, so that the entire forces have to be absorbed eccentrically at the edge 19.
  • the spring forces of a spring 12 which due to the inclined position of the corresponding spring plate 20 no longer act coaxially to the axis 18 of the tension member 8 on the abutment 15.
  • a pivoting of the sleeve 3 in the original position leads here to deformation forces within the spring due to the inclined position of the spring plate, so that with a correspondingly small-sized spring, additional frictional forces between the pull rod and the inner contour of a correspondingly deformed spring prevent the exact application of spring forces.
