Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a device for adapting the position of the cuff to the instep of a ski boot, with which the position of the cuff relative to the longitudinal midplane of the shoe can be adjusted, and by which the tension bolt can be adjusted. and a tensioning member extending through the cuff and connecting the upper to the cuff, the tensioning member being movable within a slot or angled slot and having a predetermined profile. The present invention relates to a device which can be secured in a selected position through an intermediate member. Such a device is also referred to as a tilt adjustment device since it allows the lateral inclination of the upper part of the cuff relative to the lower part of the cuff to be adjusted.

In a known device such as that described in Australian Patent No. 330020, the upper cuff portion and the lower cuff portion are interconnected by an external thread extending substantially parallel to the side of the shoe. According to the rotational position of this external thread, the two support points are adjusted relative to each other, thereby allowing an inclination of the upper part of the cuff with respect to the longitudinal midplane of the shoe. In a known device, described in U.S. Pat. No. 3,885,329, a single bolt passes through the instep and cuff and forms a support point for rotation of the cuff in the forward or backward position. . The support point is formed by an eccentric and is raised or lowered by rotation of the bolt relative to the instep.

In said known device, which is described in DE 31 35 170, a tension bolt passing through the upper and the cuff is provided, which tension bolt is fixed at one end to the upper and at the other end to the slope of the cuff. It passes through a slot. In this construction, an intermediate member provided with teeth is provided which is held in rotationally in the cuff and is pressed against the instep by the teeth when the tensioning device is actuated. ing. However, with this construction, once the tensioning device is secured, free rotation of the cuff relative to the instep is substantially prevented.

The invention proceeds from the known structure and provides a structure that can be safely latched in a selected position, so that when the cuff swings in the anteverted position or in the anteverted position, an overload does not occur at the same time on the support points. The purpose is to provide a structure that can prevent this. In order to solve this problem, the invention provides that the contour of the intermediate part, formed in particular by the teeth, engages the outside of the cuff and is pressed against it by means of a tension member. ing. In this case, the contours are formed in a particularly simple manner as teeth. However, in principle, a structure in which the intermediate member is provided with a pyramid-shaped projection can also be used. However, teeth are particularly preferably used and, as will be explained below, this also applies of course to other contours. Therefore, by the engagement of the teeth of the toothed intermediate member with the outside of the cuff, the pressing force is safely received and evenly distributed by the cuff, so that rocking of the cuff with respect to the instep is prevented. There is no risk of it happening. The selected inclination of the cuff with respect to the longitudinal midplane of the shoe is fixed by the tensile pressure and the teeth of the intermediate member, and in this way the selected state of adjustment relative to the outside of the cuff can be immediately read, for which For example, the cuffs can be provided with an indicia.

In contrast to known embodiments in which the teeth of the intermediate member are not adapted to prevent the possibility of rocking of the cuff;
According to a preferred embodiment of the invention, the outside of the cuff is provided with a mating contour, in particular formed by teeth, which cooperates with the intermediate part. An additional counter-contour in the form of a tooth as described above, which is particularly simple to implement, makes it possible to support any selected adjustment device of the cuff with relatively small surface pressure forces.

This can be done in a particularly simple manner by providing a recess in the cuff, in which a slot is arranged, and in which a small A construction is used in which the width of the toothed intermediate member is greater than or equal to the width of the toothed intermediate member. In the adapted width, the intermediate part is held non-rotatable, so that the teeth are held in a particularly advantageous manner in a position transverse to the height direction, i.e. the adjustable direction, and are tilted forward. It does not affect the ability of the cuff to swing in either the tilted position or the tilted back position. The tension member can simply be designed as a threaded bolt with a threaded drive nut on the outside. However, it is also possible to provide an eccentrically supported tightening bar at the end of the tensioning member passing through the cuff, which applies a tensioning force to the tensioning member in the closed position. In order to secure the tension member, the upper has an anchor portion aligned with a slot in the cuff and having an internal thread for receiving a thread of a tension bolt of the tension member passing through the slot in the cuff. is used in a simple manner. Such an anchoring portion is riveted to the upper, with an annular plate located between the upper and the cuff supporting the tensile forces without substantially impairing the rocking ability.

In order to improve the swingability of the cuff in the forward or backward position, the anchoring part for the tension bolt can carry a support disc facing inwardly of the cuff. This construction can be particularly advantageously implemented in such a way that the support disc has an internal thread for receiving the tension bolt and can be rotatably mounted without slipping out into the anchorage part. In this way, it is possible at the same time to improve the free swingability of the cuff in the forward or backward tilted position and to define the inclination of the cuff with respect to the longitudinal midplane of the shoe.

In order to prevent inadvertent rotation of the tension bolt relative to the intermediate member and thus loosening of the engagement of the intermediate member with the outside of the cuff, a locking bolt that can be engaged in and withdrawn from the intermediate member is provided in a preferred manner. The tension bolt may be prevented from rotating. A particularly advantageous construction of such a latching bolt, which can be latched by means of a spring into a recess or through-hole of an intermediate member, is described in Australian Patent No. 369243.

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, the upper of the ski boot 1 is designated by 2. A cuff 4 that can swing around a shaft 3 is swingably fixed to the upper 2. Said cuff is capable of pivoting about a pivot axis 3 in the direction of the double-headed arrow 5 in the forward and backward positions and has a substantially rectangular recess 6 in which the cuff can be pivoted. It is provided that the intermediate part 7 can be guided in the height direction and fixed in various positions. In this way, the pivot axis 3 can be moved in the direction of the double-headed arrow 8, thus making it possible to tilt the cuff relative to the plane of FIG. The tension member has a head 9 with a groove 10 for engagement with a screwdriver and is adapted to allow the intermediate member 7 to be crimped onto the side wall of the cuff 4.

In FIG. 2 the tension member is designated by 11. The intermediate part 7 has teeth 12 on the inside facing towards the recess 6. The tension member 11 passes through a substantially circular hole 13 in the intermediate member 7 and is adapted to be able to move in the height direction within a slot 14 in the cuff 4 in the relaxed state.

The upper 2 has a riveted anchoring part 15 in which a support disk 16 is rotatably and non-removably supported. Support disk 16
has an internal thread 17 and the tension member 11 is attached to the internal thread.
are screwed together. When the tension member 11 is fixed in the selected position in the slot 14, the intermediate member 7 is pressed against the annular plate 18 of the support disc, so that the cuff 4, together with the support disc 16, is pressed against the annular plate 18 of the support disc 16 in FIG. At a selected height in the direction of the double-headed arrow 5, it becomes possible to swing freely into a forward or backward position.

The reference numerals of FIGS. 1 and 2 are also used in the structure shown in FIG. This structure is simpler than that in FIG. 2, and the support disk 19 is formed as a part riveted to the upper 2 so as not to rotate. The tensile force of the tension element 11 is distributed over a relatively large area onto the support disk by the insertion of the intermediate element 7, so that in this case too the possibility of swinging of the cuff 4 relative to the upper 2 is ensured.

The teeth of the intermediate part 7 can be formed by teeth parallel to one edge. Note that this tooth can have a pyramid-shaped tip.
In order to facilitate adjustment, provision can be made for this intermediate member to be provided with a marking and a scale corresponding to this marking to be arranged at one end of the recess.

Teeth corresponding to the position of the intermediate member can be placed on the outside of the cuff, so as to reduce the pressing force required for secure retention.

In the structures shown in FIGS. 4 to 6, the same reference characters are used for corresponding parts. The tensioning member 11 is formed hollow, and an arcuate member 20 is inserted in the illustrated central hole in the axial direction of the tensioning member. Furthermore, a spring 21 is provided which is adapted to pull the arcuate member 20 in the direction of the arrow 22 into engagement with a corresponding recess or through hole 23 in the intermediate member 7. Said arcuate member 20 can be pulled out of its rest position in the direction opposite to the arrow 22, overcoming the force of the spring 21, and positioned in the groove 24 of the head 9 in a position rotated by 180 degrees. In this position, the head 9 and therefore the tensioning member 11 are rotated, and in any rotational position the arcuate member 20 is rotated 180 degrees, and the inwardly projecting protrusion 25 of the arcuate member 20 is rotated to the corresponding position on the intermediate member. By interlocking with the recess or through hole 23 rotation of the tension member can be prevented. In this construction, the anchoring portion designated by 26 has an axially oriented projection 27 which is adapted to prevent rotation of the anchoring portion 26 within the upper 2.
