Abstract

PROBLEM TO BE SOLVED: To adjust easily when a ski boot is fixed on the ski by matching the boot with the anatomical aspects of the leg. SOLUTION: A ski boot is formed by an instep portion 11 and a sole 12 of which the toe portion and/or heel portion project from the instep portion 11 to form fixing periphery portions for ski fasteners. The sole 12 includes an independent sole portion 15 displaceably mounted so as to intersect the longitudinal direction 16 of the sole and be parallel to the under surface 17 of the sole. This independent sole portion 15 is pivotal (in the two directions of an arrow 19) with an axis 18 extending substantially perpendicular to the under surface of the sole as the pivot center.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a leg and a sole, from which the toe and / or the heel of the sole constitute a mounting perimeter for a ski binding. A ski boot, which projects, wherein the sole comprises an independent sole that intersects the longitudinal direction of the sole and is positionally adjustable substantially parallel to the tread of the sole. .

[0002]

BACKGROUND OF THE INVENTION It is generally known that ski shoes and their soles must have high rigidity and mechanical strength in order to sufficiently stabilize the skier in the shoe and to transfer forces to the ski well. Has been. Usually, the ski boot is fixed to the ski such that the longitudinal axis of the leg of the ski boot coincides with the longitudinal axis of the sole and the longitudinal axis of the ski. As a result, the skier's legs are forced to align with the ski's axis during the ski run, and more particularly, regardless of the anatomy of the skier's ankles or knees. It Therefore, if the skier has so-called X-legs or O-legs, the joints, particularly the knee joints, are partially pained, and sometimes the tendons and ligaments are inflicted with a heavy load, and the fatigue is constantly increased. Always. In order to solve this problem, it has already been proposed to change the position of the front binding so that it can be adjusted more or less to make the angle of the entire ski boot variable with respect to the ski. However, it has been found that this measure is not sufficient to eliminate the drawbacks. This measure brings about another technical defect that, for example, even one jump makes an undesirable component of centrifugal force.

[0003] DE-C-32 25 336 shows another improvement, in which the ski boot allows an adjustable positioning with respect to the ski, a morphologically good position always being that of the user's leg. It can be obtained in relation to the characteristics.
More particularly, the sole is independent of the rest of the sole, extends transversely to the sole, and is adjustably fixed to the guide of the generally triangular ridge, ie the toe and / or the heel. , Is included. For safety reasons, play should not remain in this triangular ridge guide. Therefore, this triangular edge method is relatively difficult to operate. An independent holding tool for fixing the sole of the shoe cannot guarantee the safety very much when the temperature fluctuates rapidly. Furthermore, the known construction may move the sole of the sole to a position where it is no longer possible to hold the heel of the sole and the toe of the sole within the usual shoe-pair binding criteria.

[0004]

Starting from the last state of the art, the present invention stands out due to the durable operability of the freely displaceable shoe sole, while at the same time being adjustable in position. Is based on the task of creating a ski shoe which, no matter what the relative position, is ensured that the sole as a whole stays within the criteria for the sole of the sole and the toe of the sole.

[0005]

This problem is solved by the features specified in claim 1. According to it, the core of the invention consists in that an independent sole, i.e. an adjustable sole, is provided pivotably about an axis extending substantially perpendicular to the tread of the sole. . Handled here are the toe part, the middle part and / or the heel part, which are independent of the sole, depending on the binding used in each case.
Technical problems in practice are very few associated with the pivoted heel.

Independent adjustment of the sole is preferably accomplished by means of a threaded spindle which intersects the longitudinal direction of the sole and extends substantially perpendicular to the tread of the sole, which is a pivotable shoe. It is combined with a screw member provided in the bottom. Please refer to claims 3 and 5 to 7 for structural embodiments of the threaded member associated with the threaded spindle. An alternative construction is such that the pivotably mounted sole comprises a worm-like tooth profile on its peripheral side, which tooth profile intersects the longitudinal direction of the sole and is parallel to the tread of the sole. And a worm shaft extending in the same direction. In this construction, the spindle and gear are preferably configured in the form of a worm gear drive. Basically, it is also possible to provide a spur gear on the peripheral side. In this case, the spur gear co-operates with a pinion rotatably mounted in the sole or intersects with a rack movable inside the sole. The rotation axis of the pinion is
At that time, it extends almost perpendicular to the tread surface of the sole. The rack reciprocates freely in parallel with the tread surface of the shoe sole and intersects the longitudinal direction of the shoe sole. In the embodiment with a drive pinion, this point is even easier to handle from the underside of the sole. The rack is easy to handle, especially from the side. The same applies for the threaded spindle.

Another alternative construction has a notch member attached to the pivotably mounted sole, which cooperates with a complementary notch member to provide a predetermined pivot position along the sole. In a discontinuous manner, where the notch member is locked or unlocked via the actuating member to either the sole or the pivotable sole notch member. Of these, preferable is the case where both or either of the non-interlocking notch member and the interlocking notch member are elastically preloaded at the notch position and basically they are pushed to the notch position. . In order to pivot the sole of the shoe, this cut-out must then be pulled back from the cut-out position by an actuating member which can be actuated from the outside against an elastic preloading action. The complementary notch member is constituted by a notch pin that elastically preloads on the one hand and a notch hole group that is attached to the notch pin and is arranged along a circular arc at a predetermined angular interval on the other hand. There is. The notch pin may either be part of the pivotable sole or a fixed sole. The opposite arrangement can be similarly considered. Claims 10 to 12 relate to a structural embodiment of the pivoting mechanism of the independent sole. Claim 13 and Claim 1
Reference numeral 4 relates to an arrangement or receiving structure for an operation member that pivotally moves a shoe sole portion.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of ski shoes constructed according to the present invention will be described below in detail with reference to the accompanying drawings. In FIG. 1, a portion of a ski boot including legs 11 and a sole 12 is shown with the reference numeral 10. According to FIG. 2, the sole 12
Is itself three components or parts: a front or toe portion 13, an intermediate portion 14 and a rear or heel portion 15.
It has and. Except for the heel portion 15, the sole 12 is integrally connected to the leg portion 11 of the ski boot in a conventional manner, and more specifically, is integrally made of resin by injection molding. However, the heel portion 15 is independent of the sole 12 and the leg portion 11. Specifically, the heel portion 15 intersects the longitudinal direction 16 of the shoe sole and extends substantially perpendicular to the tread surface 17 of the shoe sole for the purpose of adjusting the position of the shaft 18 extending perpendicularly to the tread surface 17 of the shoe sole. It is pivotally mounted around. 1 and 2, the pivoting function of the heel portion 15 is indicated by a double-headed arrow 19, respectively. Heel part 1
By pivoting 5, the relative angular position of the ski boot 10 with respect to the ski can be changed, as best seen in FIG. There, the heel portion 15 is pivoted about an axis 18 to the position shown in broken lines. This causes the ski boot to be inclined by an angle α relative to the longitudinal axis of the ski, which longitudinal axis coincides with the longitudinal axis 16 of the sole at the mid position of the heel. FIG. 2 shows that the ski bindings engage the toes and heels of the sole so that no lateral moment of rotation acts on the ski even when the ski is tilted. There is. The tightening force of the binding is working unchanged, parallel to the longitudinal axis of the sole. There are no lateral forces that obliquely promote dangerous fastener slack. In this respect, the ski boot meets the criteria despite having a pivotable heel. It is self-evident that the heel part 15 is only free to pivot within a predetermined limit, preferably at an angle of ± 10 ° to 15 ° at maximum.

3 to 5, the heel portion 1 is provided so as to be pivotally movable.
Five preferred embodiments are illustrated in detail. In the case of this heel part, the pivot axis 18 is defined on the one hand by the arcuate projection in the area of the sole 12 or heel rest, and on the other hand by the corresponding arcuate groove in the pivotable heel part 15. It is also defined by 20. Adjustment of the pivotal position of the heel portion 15 is performed by a threaded spindle 21.
Intersects the longitudinal direction 16 of the sole and extends parallel to the tread surface 17 of the sole, the position of which is illustrated in FIG. 5 by its longitudinal axis 22 in relation to the heel portion 15. The threaded spindle 21 cooperates with a threaded member provided in the pivotable heel portion 15. This threaded member, in the illustrated embodiment, intersects with its longitudinal direction through a threaded hole 24 and extends parallel to the pivot axis 18 of the heel within the pivotable heel 15. It is formed as a cylindrical pivot which is rotatably held in the heel. As clearly shown in FIGS. 4 and 5, the tread 1 of the shoe sole is provided on both sides of the screw hole 24 of the pivot.
Through-holes 25, 26, each extending outward in a generally funnel shape and extending in a direction parallel to 7, are provided in the pivotable heel portion 15, and the threaded spindle 21 comprises Even if such a posture is taken, the through hole and the screw hole 24 of the pivot 23 rotatably held can be penetrated and extended without interference. Funnel-shaped holes 25, 26
Is characterized by a total opening angle of 30 degrees in the illustrated embodiment.

As an alternative to the pivot 23, a threaded bushing may be provided in the heel portion 15 that is pivotally held about an axis in the heel portion 15 that extends parallel to the pivot axis 18 of the heel portion. . However, the embodiment shown in FIGS. 3 to 5 and described with reference to these figures is preferred in terms of manufacturing technology. The longitudinal axis of the pivot 23 is at the same time the pivot axis of the pivot 23 which is parallel to the pivot axis 18 of the heel 15 and is designated by the reference numeral 27 in FIGS. 4 and 5. The cooperation of the threaded spindle 21 and the pivot 23 makes it possible to continuously adjust the heel part 15.

Similarly, depending on the structure, it may be possible to individually displace the heel portion 15. In that case, the heel part 15 is provided with a toothed shape on its arcuate front face toward the toes of the sole, which cooperates with a spindle which intersects the longitudinal direction of the sole and extends parallel to the tread of the sole. Would work, where the peripheral teeth and spindle would be configured in the form of a worm gear drive. Obviously, in both such an embodiment and the embodiment described with reference to FIGS. 3 to 5, the operating spindle can rotate in the axial direction without play in the shoe sole 12 or its supporting member. It is provided so that there is no play. This supporting of the operating spindle on the sole is essential for the pivoting movement of the heel part 15.

The operating spindle 21 is preferably externally accessible and, in the embodiment according to FIG. 1, is operated laterally by means of a screwdriver. The end of the threaded spindle 21, which is accessible from the outside, is therefore formed in the form of a negative screw head (see FIG. 1) or a positive screw head. Furthermore, the pivot axis 18 of the heel part 15 is also defined by a central pin which extends perpendicularly to the tread surface 17 of the shoe sole and at the same time serves to fix the pivotable heel part to the shoe sole 12. However, this requires additional components such as the center pin. In this respect, the embodiment described with reference to FIGS. 3 to 5 is configured in a simplified manner to some extent, and more specifically, it serves to pivot the heel portion 15 first and then hold it on the sole of the shoe. 2 of the threaded spindle 21
It also has a heavy function. In the embodiment according to FIGS. 3 to 5, the heel part 15 is first held by the arcuate part defining the pivot axis, that is to say by the projection on the sole side and the groove 20 on the heel part side, and then by the threaded spindle 21. Hold it.

At the rear end of the pivotally provided heel portion 15, there is provided a heel pad 29 made of replaceable hard rubber or the like on the lower side of the heel portion. The heel pad is fixed by gluing or screwing. Reference numeral 30 is attached to the corresponding screw hole of the movable heel portion 15. The heel pad 29 has a semicircular shape in a plan view, and a triangular protrusion is formed in a diameter region defined by the semicircle, and this protrusion cuts into a corresponding triangular notch of the heel portion 15. By doing so, the heel portion 15 and the heel pad 29 can be properly engaged and connected properly. The heel pad 29 is shown schematically in FIGS. 4 and 1.

Finally, it should also be mentioned that the pivotally provided heel 15 together with the complementary notch member of the sole 12 cooperates for the discontinuous adjustment of the predetermined pivot position. It can be said that it is also possible to attach a working notch member, and in this case, this notch member is either the shoe sole or the pivotable heel notch member via the operating member. To
Locked or unlocked. In this connection, also refer to the first treated example. The arcuate front surface 28 of the pivotally provided heel portion 15 has substantially no play on the corresponding circular outer peripheral surface of the sole 12 or the heel portion as shown in FIGS. 1 and 2. Adjacent in a fitted state. The center point of the arcuate front surface 28 and the outer peripheral surface complementary to that of the shoe sole is on the pivot axis 18 of the heel portion 15, and the arcuate groove 2
The center point of 0 is also in the same place (see FIG. 5). The entire features disclosed in this application are claimed as an essential part of this invention, to the extent they are novel to the state of the art, either individually or in combination.
