Definitions

  • the invention relates to a device for supporting a foot in the instep, flexion and / or shin area of a shoe, in particular ski boot, with a support plate which is supported relative to the shell of the shoe and is adjustable in its position.
  • the invention now aims to improve the fit within a shell and, above all, in the area of a shoe to achieve an exact adjustment and support of the template forces, which experience has shown that it is subject to the greatest individual fluctuations.
  • the device according to the invention therefore aims above all to offer an exact support and improvement of the hold in the lower shaft area in order to be able to keep the upper shaft area free of constricting adaptation forces.
  • the device according to the invention consists essentially in that an im essentially in the longitudinal direction of the shoe, which can be brought into operative connection with the support plate, is provided, the actuating element is located on the outside of the shell and the effective length 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 reliable support for the forces acting on a plate arranged in particular in the flexion and shin area.
  • the actuating member which must be accessible on the outside of the shell, can in a simple manner from a ring nut can be formed, 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 that can be actuated from the outside.
  • the design is such that the actuator is pivotable Lever is formed 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 has the pressure piece which interacts with the support plate.
  • 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 length of the pressure piece is adjustable and adjustable and preferably has at least one bolt which can be screwed into a nut thread.
  • the pressure piece is easily accessible after pivoting the pivotable lever and it is therefore easy to adjust the length at this point.
  • the support plate is preferably arranged above the actual instep area in the flexion and shin area between the shell and inner shoe, the transmission of force from the pressure piece to the support plate is advantageously ensured in that the support plate carries a preferably resilient extension whose free end with the pressure piece can be brought into operative connection.
  • the resilient extension serves primarily for the uniform application of force to the support plate, which can itself be made of flexible material. Due to the resilient power transmission, local overstressing and pressure points are avoided and there is a compensation of the Pressure piece on the support plate transferred pressure ensured over the surface of the pressure plate.
  • the free end of the extension can preferably have at least two points of attack 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 being able to be carried out directly on the pressure piece itself .
  • a further improvement in the introduction of force into the pressure plate can be achieved in that the extension is connected in an articulated manner to the support plate, a particularly simple design being provided if the extension is designed as a spring steel strip or spring steel rod.
  • the design is made in a particularly advantageous manner so that the pressure piece is resiliently supported on the lever about its pivot axis on the lever in the direction of the shell.
  • the design is such that the pressure piece with its free end facing away from the point of attack or articulation on the lever in releasable positive connection with the Attack points can be brought to the extension. In this way, after a short-term relief, the correct position does not have to be sought again, but it is sufficient to press the actuating element formed by a lever into its closed position again.
  • the training also serves to facilitate the fine adjustment of the length of the pressure piece itself, since when the lever is open, the adjusting members for the length adjustment come into a defined position in which they are easily accessible due to the positive connection with the points of attack on the extension. At the same time, with such a positive connection to the points of attack on the extension, an opening of the lever leads to a relief in the region of the support plate which is supported by the opening movement of the lever, since this is subjected to tension in the event of such an opening in the case of a positive connection with the pressure piece.
  • the actuating member in particular the pivotable lever, can dip into a recess in the shell in the closed position, which results in a smooth and flowing outer contour of the shoe.
  • the free end of the lever preferably has an actuating recess or a two-armed auxiliary lever, the inward arm of which cooperates with the base of the recess with the lever. In this way, the lever can be brought into a pivot position either by engaging in the actuating recess or by actuating the auxiliary lever, which facilitates the complete opening of the lever.
  • the design can be such that the pressure piece has a spring leaf interacts, which is fixed at its free end to the shell or the cuff and at least partially overlaps the support plate.
  • the pressure piece causes a curvature of the spring leaf and thus a distribution and introduction of the pressure acting on the support plate over a larger area of the support plate.
  • the support plate itself can be supported on the shell or the cuff.
  • the articulation point of the support plate on the inside of the shell is designed to be adjustable in the height direction, a more precise adjustment being made possible in the forefoot area in particular when this articulation point is arranged in the front end region of the support plate.
  • FIG. 1 shows a longitudinal section through a shoe with a first embodiment of the device according to the invention
  • 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 a further modified embodiment.
  • 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 illustrated schematically by a Union nut 10 indicated, in 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 arrow 16, the pressure piece 9 comes into 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 to an extension 16 via an articulation point 22, which extension 16 can in turn be designed as a band spring or resilient rod.
  • the actuating lever is again designated 6 and on the axis 7 in the front area of the shell the shell is pivoted.
  • 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 advantageously provided on the articulation axis 8 of the pressure piece 9, which spring holds the free end of the pressure piece 9 in contact with the base 18 of the recess for the lever 6 .
  • Fig. 3 a modified design in an analogous representation as Fig. 1 is partially shown in section.
  • the pressure piece 9 is only indicated schematically here and interacts with a spring leaf 23 which overlaps the support plate at least in the upper region.
  • the pressure piece 9 causes the spring leaf 23 to arch in the direction of the support plate 14 and thus to evenly apply force to a larger area of the support plate 14.
  • the support plate 14 is fixed in the front end region to the shell 2 via an articulation axis 24.
  • This articulation axis 24 can be adjusted in height by means of a screw 25 in order to achieve a more precise adjustment in the forefoot area.
