Description

Ski boot

The invention relates to a ski boot with a sole plate and a shell and with a support which can be fixed above the ankle on the lower leg and which is connected to the sole plate via a yoke.

In a shoe of this type which has become known from AT-PS 296 843 (= FR-A-20 24 307), a support which consists of two side parts, one of which is the leg, engages the leg just above a ski boot with a low shaft enclosing band is attached. The side parts are attached to the upper ends of two yoke parts made of rod material on the side of the shoe by means of a thread, so that height adjustment is possible. The lower ends of the yoke parts are mounted in a sole plate so as to be pivotable about a common horizontal axis against the restoring force of a spring device. This known leg support is, in principle, an additional part of a low-profile ski boot, with the fear that strong pressure on the leg, either from the upper edge of the shoe or from the narrow cuff, will occur if the shin is in front or behind.

From AT-PS 333 154 a ski shoe with a leg support emerges which engages the leg just below the knee and which is connected to the sole or shell of the shoe via a correspondingly long yoke. It is provided that the yoke can be pivoted to a limited extent with respect to the shoe. Here, too, the leg support forms an element which is essentially separate from the ski boot, and the disadvantages described above are also to be expected. In addition, according to the exemplary embodiments shown, a large part of the lower leg remains completely unprotected against mechanical and thermal influences.

ERSAT2B ATT FR-PS 959 743 discloses a board-like, roller-skate-like sports device onto which a shoe can be strapped, a yoke with a leg support being fastened to the sports device in a fixed, pivotable or adjustable manner. The support engages just below the knee on the leg. As can be seen from the drawings in this document, there is no connection between the shoe on the one hand and the sports equipment including footrest on the other.

The well-known leg supports work too hard on the leg and can hardly or only be adapted to the individual circumstances (anatomy, ability of the athlete).

It is an object of the invention, among other things, to eliminate these disadvantages in the simplest possible manner and to effectively meet the needs for individual, anatomically correct support, the natural pivoting movement of the lower leg being taken into account.

This object is achieved on the basis of a ski boot of the type mentioned at the outset in that, according to the invention, the support is designed as a closable sleeve which interacts with at least one shell part and which preferably has the yoke in a between two with a yoke which comprises approximately half the lower leg circumference Closures of the cuff lying height is connected.

In addition to an advantageous and also soft transfer of forces between the leg and the shoe or a sports device, the invention provides the possibility of achieving an adaptation which corresponds to the individual anatomy, the prevailing driving conditions and the respective abilities.

Further features of the invention result from the subclaims. The invention together with other advantages is explained in more detail below using exemplary embodiments which are illustrated in the drawing. 1 shows a side view of a touring ski or snowboard shoe with a two-arm yoke, FIG. 2 shows a bottom view of the shoe according to FIG. 1, FIG. 3 shows a rear entry shoe with a two-arm yoke, FIG. 4 shows a ski boot according to FIG Invention, in which the yoke is formed by a rear shell part, FIG. 5 shows a detail of a rear section of a ski boot with a two-arm yoke, and FIG. 6 shows a section along the line VI-VI in FIG. 5.

The ski boot shown in Fig. 1 has a sole plate 1 and integrally formed with this a rear shell section 2, side shell sections 3 and a front shell section 4. The shoe is provided with a yoke 5, the two laterally extending, each consisting of two arm parts 6a, 6b has existing arms 6, the lower ends of which can be firmly connected to the rear sole plate region. The yoke 5 is provided in one piece with a bracket 7 at its upper end, in which a cuff 9 with padding 10 is supported by means of lateral pin-slot connections 8 as leg support. The cuff 9 cooperates with a tongue 12, which is only indicated, with a tongue 12, which is displaceably mounted on the side and front shell sections 3, 4, the range of motion of the tongue 12 being limited by means of a pin-slot connection 13. For sealing against moisture and snow, a bellows 14 is provided between the rear shell section 2 and the sleeve 9, which bellows does not restrict the mobility of the sleeve 9.

The yoke 5 is designed so that it is stiff with respect to laterally acting forces. The yoke 5 is, however, adjustable in height, for which purpose the two-part arms 6 - arm parts 6a, 6b - on both sides - each by means of a screw-slot connection. 15 can be changed in length and can be fixed in different positions. In this way also set an unequal arm length and thus a lateral inclination of the yoke 5, which is called adjustable canting. The lower arm parts 6b could be formed in one piece with the rear shell section 2 or at least partially formed by this shell section.

As shown, a lower pin-slot connection 25 can also be provided. This has the advantage that after loosening the screw on the connection 25 and completely unscrewing the screw on the connection 15, a free pivoting movement of the yoke 7 is made possible, e.g. is desired when using the shoe as a touring shoe.

The lower arm parts 6b of the laterally extending arms 6 of the yoke 5 have plate-shaped end parts 33r, 331 which are angled inwards by approximately 90 ° and have toothed edges 34, which can engage in a positive manner in corresponding toothings of the adjacent soleplate parts. The end parts 33r, 331 are further connected to the sole by means of pin-slot connections 35, and after loosening screws 36, which form the pins of the pin-slot connections 35, they are lifted out of the positive engagement via the toothings and can be adjusted further outside or inside. After tightening the screws 36, the end parts 33r, 331 and with them the arm parts 6b remain immovable with respect to the sole plate 1 in their new position. This type of width adjustment at the lower end of the yoke naturally requires a corresponding flexibility of the arms 6, which can be achieved by a suitable choice of material.

The pin-slot connections 8 between the bracket 7 and the sleeve 9 can serve different purposes. Either they can allow free movement between the collar 9 and the bracket 7, or - when using a damping insert described later - a damped mobility or, if the pins are designed as tightenable clamping screws, they can be used to fix the relative position between the bracket 7 and cuff 9 serve. The shoe according to FIG. 3 is intended as a rear entry shoe and therefore has a tailgate 26. Here, the yoke 5 is formed in one piece with the sole plate 1 or is firmly connected to it and has an integral bracket 7, which, however, runs around the tongue 12 at the front. The tongue 12 and the tailgate 26 are connected to one another by means of a closure 11 (only indicated). A pin-slot connection 8 between bracket 7 and tongue 12 is similar to that of FIG. 1 or, which will be described in more detail later, can have a damping insert. As in FIG. 1, the tongue 12 is displaceably mounted in the instep area along a shell section. The cuff 9 is here formed by the upper section of the tongue 12 bent around the leg and interacts with the tailgate 26 via the closure 11.

As with all of the embodiments described here, the bracket 7 extends by at least a quarter, but preferably half, of the lower leg circumference in order to ensure the very important lateral support together with the leg support, which is formed here by the tailgate 26 and tongue 12.

4, a toe cap 27 and a rear shell, which forms the yoke 28, are adjustably connected to the sole plate 1 in a manner not forming the subject of the invention. On this yoke (or rear shell), the bracket 7 can be readjusted and fixed by means of a cross-head pin connection 29 of the height and the side inclination (canting). On the other hand, by means of a pin-slot connection 8 - corresponding to that according to FIG. 1 or 3 - a sleeve 9 is arranged as a leg support on the bracket 7, which cooperates with a tongue 12 via two indicated closures 11a, 11b. The partially open shoe shown here is covered by a cover, not shown, which offers protection against moisture and snow, or it has a waterproof inner shoe. In this embodiment, the connection of the cuff to the bracket takes place at a height that lies between two closures 11a, 11b of the sleeve 9, ie the pin-slot connection 8 and thus a possible pivot point of the sleeve 9 with respect to the bracket 7 is symmetrical in height ¬ tric to the two closures 11a, 11b. This results in a particularly desirable application of force to the foot.

The ski boot illustrated in FIG. 5 has a heel shell section 39 pulled up by the sole plate 1, a middle shell section 40 and a front cap (not shown), a tongue and a cuff 9. The cuff 9 is mounted on both sides on a bracket 7 by means of pin-slot connections 8 which is in one piece with the yoke 5.

The yoke 5 has two lateral arms 6, which are supported at their lower ends near the sole plate 1 on the shell sections 40 connected to the sole plate in bearings 42, which are described in more detail below.

Under certain circumstances, for example for racing, it may be expedient to provide a stabilizer bar 43 on the rear of the shoe, which connects the bracket 7 to the sole plate 1 or the heel shell section 39.

In the present case, the stabilizer bar 43 is articulated on a tab 44 projecting from the shell section 39 by means of an articulated connection 45. The articulated connection should also allow a certain lateral inclination of the rod 43, for example by ± 6 °, so that a canting adjustment by means of the bearings 42 is not hindered. The rod 43 can be adjustable in length. In the present case, a threaded sleeve 46 is rotatably mounted at the end of a bolt 47 articulated on the articulated connection 45 and can be screwed to a threaded bolt 48, which on the rear side of the stirrup 7 on the outside or inside, in the present case on the inside, by means of a bolt 49, one Rivets or the like preferably around this bolt is pivoted. In this way, the total length of the stabilizer bar 43 consisting of the parts 46, 47, 48 can be changed. Furthermore, it is expedient if the rod 43 can be temporarily unhooked at its upper or better lower end, for example to allow the lower leg to move more freely when walking.

A temporary pivoting of the yoke 5 to the rear could also be achieved by means of an articulated joint in the rod 43, a screw or sliding sleeve similar to the sleeve 46 being able to be screwed or pushed over this articulated joint when the rod parts are aligned in order to fix the yoke. In order to make it possible to bend, the upper section of the rod 43 would of course have to be articulated on the bracket 7 so as to be pivotable about a transverse axis. It is also possible to insert a damping element, e.g. insert a gas pressure shock absorber, which can be exchanged, removed or blocked.

The shoe shown in Fig. 5 is provided with a padded, waterproof inner shoe, not shown. Therefore, the shell parts do not necessarily have to form a tight shell and it is possible to leave a recess 51 in the ankle area between the cuff 9, tongue and the shell section 40, which contributes significantly to the comfort of the shoe. The shell sections 40 and thus the arms of the yoke 5 mounted on them can be adjustable in the transverse direction with respect to the sole 1, for which reference is made, for example, to the width adjustment of the arms 6 and the end parts 33r, 331 according to FIGS. 1 and 2.

The two lateral arms 6 of the yoke 5 are mounted in the bearings 42 on the shell sections 40, which can be adjustable with respect to the sole 1, so that they can be adjusted and locked. A threaded bolt 52 is used for this purpose, which is guided in an elongated hole 53 which is formed in the shell section 40 and extends obliquely upwards and which penetrates a bore 54 in the yoke arm 6. The bolt 52 can The inside of the shoe, for example, has a flat head and is provided on the outside with a hexagon nut 55.

The arm 6 lies with its inner surface on a flat bearing surface 56 of the shell section 40, the inner surface of the arm 6 and the bearing surface 56 being formed with a rough, friction-increasing surface structure. This makes it possible to adjust the arm 6 translationally in the direction of the elongated hole 53 and rotationally about the axis of the bolt 52 and to hold it in the desired position by tightening the nut 55. This results in a further possibility of adaptation to anatomical characteristics or the desired driving style.

The same bearing 42 as shown here for the right side of the shoe is also provided on the left side. The nuts 55 are usually protected by a cover cap, not shown here.

At the front ends of the bracket 7, a pin-slot connection 8 is provided on the left and right, which is described in more detail below.

At the front end of the bracket 7, a hollow fitting part is fastened with the aid of two rivets 57 (FIG. 5), which is designed here as a U-shaped sheet metal strip 58. A longitudinal slot 22 extends through the bent sheet metal strip 58.

On the cuff 9, a threaded bolt 59 is attached so that it protrudes outward from the cuff 9 and passes through the slot 22. At its inner end, the bolt 59 is provided with a metal plate 60, which is held in the material of the sleeve 9 in a torsion-proof manner with bent edges 61. On the outside of the sleeve 9 there is a flat nut 62 which is domed on the outside in a dome-like manner and at the outer end of the bolt there is a flat nut 63. The inside of the bent sheet metal strip 58 contains a damping insert 20, which consists of an elastic rubber or plastic strip or piece, which - compared to the material of the bracket 7 or the sleeve 9 is relatively soft. Instead of such an elastomer piece, a suitable metallic spring could also be used. It can be seen that when the sleeve 9 moves with respect to the bracket 7, the damping insert 20 is compressed. The effective length of the insert 20 is set by means of a cotter pin 64, which is shown in FIG. 5 to the right of the sheet metal strip 58 outside its intended position in side and front view. Such a pin 64 can, as indicated by dashed lines, be inserted between the legs of the sheet metal strip 58 through the insert 20, its upper or lower widened end being held in position between cut-out, bent claws 65.

It should also be noted that the curvature of the nut 62 permits a certain degree of tilting movement of the bolt 59 and thus of the cuff part connected to it with respect to the sheet metal strip 58 and thus of the bracket 7. This enables the cuff 9 to be automatically aligned with respect to the rigid or largely rigid strap 7, which contributes to the comfort of the shoe.

If desired, the sheet metal strip 58 can be displaceable with respect to the bracket 7 and can be adjusted in various positions relative to the bracket 7, which results in further possibilities for adaptation.
