  • EP-A 84 89 0229.2 aims to improve the fit within a shell and, above all, to achieve an exact adjustment and support of the forces in the area of a shoe, which experience shows that the greatest individual fluctuation is subject.
  • the inventive device aims Dahe l above all on at offering an exact support unc improve the balance in the upper shaft to be able to freely hold the upper shaft area of constricting adjustment forces.
  • a pressure piece running essentially in the longitudinal direction of the shoe which can be brought into operative connection with the support plate, is provided, the actuating element of which is on the outside of the shell and the effective length of which is adjustable and adjustable.
  • a pressure piece running essentially in the longitudinal direction of the shoe is provided, which can be accommodated in a particularly stable manner in the instep area of a closed shell, the effective length of which is adjustable and adjustable, supporting forces are introduced into the shell in the longitudinal direction and can in this way safely absorbed by the shell without any significant deformation of the same.
  • This construction is particularly advantageous for ski boots, in which the forefoot area is self-contained and entry is possible after a swiveling rear section has been folded down.
  • the cuff and the rear part of the boot are each designed as a half-shell and can be pivoted relative to the shell.
  • the instep area of a ski boot with a closed shell is extremely dimensionally stable and therefore provides a reliable support for the in particular in the flexion and
  • the actuating member, which must be accessible on the outside of the shell, can be formed in a simple manner by a ring nut into which threaded bolts of the pressure piece can be screwed.
  • the pressure piece it is readily possible to design the pressure piece as a hydraulic or pneumatic cylinder-piston unit with a pressure medium supply or pump which can be actuated accordingly from the outside.
  • the design is such that the actuating member is formed by a pivotable lever in the instep area of the shell, the pivot axis of which extends essentially transversely to the longitudinal axis of the shoe, and that the lever on its side facing the shell is the pressure piece has, which cooperates with the support plate.
  • a swiveling actuating device depending on the distance between the articulation point of the swiveling lever on the shell and the point of application of the pressure piece on the swiveling lever, any lever ratios can be set and a relatively high compressive stress can be applied with relatively little effort.
  • the pressure piece can be designed as a spring tongue or can be pivoted in a simple manner on the lever about an axis parallel to the pivot axis of the lever, whereby the actuation and adjustment of the effective length is considerably simplified.
  • the present invention aims to improve the power transmission from the pressure piece to the support plate and to ensure that a comfortable fit in the shoe is ensured even when the shaft is pivoted relative to the shell.
  • the invention consists essentially in the fact that the pressure piece cooperates with a spring leaf-like element, which at its the point of attack Pressure piece facing away from the inside of the shell or the shaft is articulated or fixed.
  • the support plate has a preferably resilient extension, the free end of which can be brought into operative connection with the pressure piece, the introduction of force is now evened out by the fact that when the spring leaf-like element is pressed by the pressure piece, a more or less strong deflection of this spring leaf-like element is achieved. Due to the deflection of the spring leaf-like element, the compressive force is now exerted on the support plate and the support plate itself is not subjected to deflection. The pressure is distributed even better over the surface of the support plate in this way and there are less demands on the flexibility of the support plate than in a configuration in which the support plate carries a resilient extension.
  • the support plate can be made stiffer and better padded. At the same time, the thick dimensions of the support plate can be reduced with such a design.
  • the lower end of the support plate facing the toe is articulated or fixed on the shell.
  • a good position fixation of the support plate is achieved and a favorable load compensation is achieved when the shaft is pivoted relative to the shell.
  • the configuration is preferably such that the spring-leaf-like element engages over the support plate in the longitudinal direction of the shoe.
  • the pressure piece is preferably designed as a resilient clamp in which a part of the support plate, an extension thereof or the spring leaf-like element can be inserted.
  • the clamp By actuating the resilient clamp, the clamp can be brought into clamping connection at various points in the extension, the spring-leaf-like element or the support plate, as a result of which a rapid change in the effective length of the pressure piece is achieved.
  • the design is such that the clamp consists of a lower part which can be pivoted relative to the pivotable lever and an actuating part which passes through an opening in the pivotable lever and is pivotably articulated on the pivotable lower part. In this way, an elegant design is also ensured and the clamp can be actuated at any time by breaking through the pivotable lever.
  • the free end of the extension can preferably have at least two attack points for the pressure piece lying next to one another in the axial direction of the extension, in particular in longitudinal section, the fine adjustment then subsequently directly on the pressure piece itself can be made.
  • this design is preferably developed so that the extension of the support plate or the spring-leaf-like element carries a sawtooth-like profile, the steep flanks of which face the pressure piece, and that the ends of the clamp facing the extension can be brought into engagement with the sawtooth-like profile.
  • the clamp By actuating the clamp, the clamp can thus be moved relative to the sawtooth-like profile of the extension and after the clamp is released, the clamp engages in the respective position of the sawtooth-like profile.
  • the steep flanks of the sawtooth-like profile ensure secure support in the pressure direction, and the arrangement of the steep flanks in the direction of the pressure piece allows rapid adjustment by ratcheting the sliding over the flatter flanks Realize clamp.
  • the clamp engages in the new position because it cannot step back in the opposite direction due to the steep flanks without actuating the clamp.
  • the actuating element according to the parent patent in particular the pivotable lever, can be immersed in a recess in the shell in the closed position, which results in a smooth and flowing outer contour of the shoe.
  • the pivotable lever preferably has a lateral actuating extension which overlaps the shell of the shoe. In this way the simple actuation of the pivotable lever is possible without unintentional adjustment of the clamp, since the extension forms the actuating part of the pivotable lever and is spatially separated from the point at which the clamp can be actuated.
  • FIG. 1 shows a longitudinal section through a shoe with a first embodiment of the device according to the parent patent
  • FIG. 2 shows an enlarged partial view of the instep area of such a shoe with a modified embodiment of the device according to the invention
  • FIG. 3 shows an embodiment of the actuator in accordance with the invention 4 and a side view of the embodiment according to FIG. 3
  • FIG. 5 a further embodiment of the device according to the invention in longitudinal section analogous to FIG. 1 and FIG. 6 a modified embodiment analogous to the illustration in FIG. 5.
  • Fig. 1 the shell of a ski boot 1 is designated 2.
  • a tailgate 3 and a cuff 4 are pivotably connected to this shell 2, the corresponding pivot axis being approximately in the ankle region of the shoe.
  • An inner shoe 5 is arranged inside the shell 2.
  • a pivotable lever 6 is arranged, the pivot axis 7 of which extends essentially transversely to the longitudinal plane of the shoe 1.
  • a pressure piece 9 is pivotally articulated on the actuating lever 6 about an axis 8, which runs essentially parallel to the pivot axis 7, the length of which can be variably adjusted.
  • the adjusting device is indicated schematically by a union nut 10, into which the bolt threads of the two parts of the pressure piece are immersed.
  • the free end 11 of the pressure piece 9 engages at points of attack 12 of a resilient extension 13.
  • the extension 13 is connected to a support plate 14 made of elastically deformable material.
  • the support plate 14 lies on the shin side of the inner shoe 5 and is supported at 15 on the shell.
  • the points of attack 12 on the resilient extension 13 are sawtooth-like in longitudinal section, so that the desired pressure on the support plate 14 can be roughly adjusted at this point.
  • the attack of the free end 11 of the pressure piece 9 can only be non-positively in the pressure direction.
  • it is advantageous to provide a releasable positive connection so that after opening the lever 6 against the direction of the arrow 16 the pressure piece 9 reaches a defined position in which the actuation of the adjusting member or the union nut 10 is particularly easy.
  • the resilient extension 13 can be guided on the inside of the shell against lateral displacement, so that an exact introduction of pressure is made possible.
  • the support plate 14 is connected via an articulation point 15 to an extension 16, which extension 16 can in turn be designed as a band spring or resilient rod.
  • the actuating lever is again designated 6 and pivoted about the axis 7 in the front region of the shell on the shell.
  • This actuating lever 6 cooperates with its free end with a lever 17 which is articulated on the shell, for example near the base 18 of the recess. By pivoting, this lever 17 causes the lever 6 to be raised in the direction of the arrow 19. At the same time, this lever 17 enables the extension 16 to be guided in the closed state of the lever 6.
  • the lever 6 can be pivoted into the open position shown in broken lines, wherein the articulation axis 8 of the pressure piece 9 comes into a position as it corresponds to the illustration in FIG. 1.
  • the pressure piece is in turn equipped with a threaded bolt which can be screwed into a nut 10, as a result of which the effective length of the force transmission between the lever 6 and the flexible support plate 14 can be adjusted.
  • a spring 21 is provided which holds the free end of the pressure piece 9 in contact with the base 18 of the recess for the lever 6.
  • an actuator 21 is shown, which is articulated analogously to the lever 6 on the shell of a ski boot.
  • the lever 21 has an opening 22 through which part of the pressure piece can pass, the pressure piece now being designed as a clamp, as can be seen more clearly from FIG. 4.
  • the lever 21 also has a lateral extension 23 which engages over the outside of the shell and in this way facilitates the actuation of the lever 21.
  • the pressure piece now consists of a lower part 25 which is pivotably mounted about an axis 24 and on which an actuating part 27 is pivotably pivoted about an axis 26.
  • the free end of the actuating part 27 is designated by 28 and a spring 29 is provided which resiliently pivots this free end 28 in the direction of the pivotable lower part 25.
  • the free end 28 thus exerts a clamping effect on a part of the support plate or an extension inserted between the lower part 25 and the free end 28.
  • the actuating part 27 is depressed, as a result of which the free end 28 comes out of engagement with a part of the support plate or an extension thereof, the actuating part 27 having a convex recess 30 to facilitate depression.
  • the pressure plate 14 is supported with its lower end on the shell 2.
  • a rivet connection 31 is provided for the fixing.
  • a spring leaf-like element 32 is articulated or fixed on the shaft 3, a rivet connection 33 being provided for this.
  • the spring-leaf-like element 32 is fixed at the end of the pressure element facing away from the spring-leaf-like element 32, and the spring-leaf-like element 32 overlaps the support plate 14 when viewed in the longitudinal direction of the shoe.
  • an actuating lever 34 is provided, in which a pressure piece 35 passing through this actuating lever 34 is pivotably mounted.
  • the pressure piece 35 is pressed resiliently in the direction of the spring leaf-like element 32 and engages with its free end in a sawtooth-like profile 36 of the spring leaf-like element 32.
  • the actuating lever 34 is pivoted in the direction of the arrow 37, the spring leaf-like element 32 is thus curved more strongly and exerts a pressure in the direction of the arrows 38 on the support plate 14.
  • the pressure distribution adapts extremely favorably to the actual anatomical shape of the foot.
  • the actuating lever differs from the embodiment according to FIG. 1 only by a lateral extension 39, which makes it easier to use.
