Definitions

• the present invention relates to a ski boot according to the preamble of claim 1.
• Ski boots especially those in back to back Unfolding a rear part of the shaft that covers the heel and encloses the lower part of the calf and that on one, the Front shaft part that covers the foot, pivotable gela equipment, is boarded, often show the deficiency, that the heel does not find a good grip. However, this is for a good transfer of the steering forces from the foot to the ski necessary.
• There are ski boots made for this purpose Clamping pads arranged in the heel area on the inner shoe exhibit that on the calcaneus in the area of the Hold the Achilles tendon in place. To get started with the These clamping pads can not complicate the ski boot can not be made arbitrarily large. This can do this lead to the fact that the clamping pads are often too little full in the area the heel touches the foot.
• the object of the invention is therefore to provide a holding arrangement on the heel bone in the area of the Achilles tendon acts to suggest that regardless of the foot shape of the skier gives this a secure hold and Nevertheless, it does not hinder getting into the ski boot.
• a ski boot which has a front, stiff shaft part that covers the foot and on which in the area of the ankle joint an upper part that encompasses the lower part of the shin and one that encompasses the heel and the lower part of the calf rear shaft part are pivotably mounted.
• the front shaft part In the area of the heel, the front shaft part has an upwardly projecting rigid tab which can be brought into action on the heel bone in the area of the Achilles tendon.
• On the rear part of the shaft a parallel to the sole and at right angles to the longitudinal direction of the shoe Ge threaded rod is rotatably mounted.
• the wedges are adjustable in their mutual distance by means of the threaded rod and act with their wedge surfaces on the outside of the bracket.
• the rigid flap is pressed in the direction of the front part of the shaft. This force directed towards the front is transmitted through the inner shoe to the foot, which is thus pressed against the front shaft part and against a holding device that covers the foot in the form of a saddle in the instep area.
• the distance can between the holding elements, if necessary, for the Getting in and out of the ver can be enlarged and adjusted by adjusting the distance a secure hold for every foot regardless of its shape conveyed. Since the retaining elements are on the inside of the Shank are provided, they act directly on the Inner shoe or on the foot, if necessary via a the holding elements arranged upholstery.
• a particularly convenient setting of the distance between the holding elements is made possible if this by means of an adjusting device arranged outside the shaft nes is adjustable.
• the Hal The arrangement is particularly simple and they need it takes up very little space.
• the Adjustment one out of its operating position in a rest position foldable toggle which is in the Rest position to lie in a recess in the shaft comes.
• the toggle In the actuated position, the toggle enables the adjustment of the distance between the holding elements with little effort and in the resting position he stands not over the shell in front, so that an injury of the Gag, an unwanted change in the setting of the Distance or getting stuck on a foreign object is avoided.
• An embodiment according to claim 7 allows a be Particularly good adaptation of the holding elements to the shape of the foot in the heel area.
• the ski boot 10 has a sole 12 and a shaft 14. On one that covers the foot front shaft part 16 are in the area of the ankle joint an upper, encircling the lower area of the shin fender shaft part 18 and a heel and the lower Rear shaft part 20 encompassing part of the calf pivoted.
• the upper and rear shaft part 18, 20 are by means of a conventional lock 22 against each other tensionable.
• Inside the shaft 14 is a padded inner shoe 24 arranged over the upper ends of the upper and rear shaft parts 18, 20 protrudes.
• a holding arrangement is located on the rear shaft part 20 tion 26 is provided, which the inner shoe 24 against the side the heel bone presses in the area of the Achilles tendon.
• Fig. 2 are the rear shaft part 20, the inside shoe 24 and the holding arrangement 26 in one section along the line II - II of FIG. 1 enlarged Darge represents.
• the axis 34 of the threaded rod 30 runs parallel to the sole 12 (see Fig. 1) and across the shoe longitudinal direction, indicated by the dash-dotted and with 36 indicated line is indicated.
• the threaded rod 30 is rotatable on the rear shaft part 20, but not mounted longitudinally displaceable and has two counter-rotating Thread 38, 38 'on.
• the holding elements 28 sit with each a part 40 in which a corresponding internal thread 42, 42 'is arranged on the threaded rod 30.
• the distance between the solid lines shown set holding elements 28 is denoted by B.
• This Distance B is by turning the threaded rod 30 by means of of the toggle 32 can be changed.
• dashed lines are the holding elements 28 with a minimum distance B and the shape of the inner shoe 24 which has been changed as a result is indicated.
• Fig. 3 is only part of the rear shell part 20 shown with the recess 48.
• the toggle 32 is with solid lines in the actuation position and with dashed lines and 32 'denotes at rest position specified.
• With the arrow C is the Schwenkrich direction of the toggle 32 around the shaft 46 designated.
• the on the threaded rod 30 seated retaining elements 28 have Elongated holes 50, which the adaptability of the holding elements 28 to improve the shape of the foot.
• the holding assembly 26 works as follows: Before The holding elements 28 are for getting into the ski boot 10 ge by the greatest possible distance B from each other separates so that the holding elements 28 laterally on the rear Shell part 20 are in contact. As shown in FIG. 2 with is shown in solid lines. This is enough Free space to put your foot in the front part of the shell 16 slide in and also the heel on the sole 12 to turn off. Then the upper and rear Shaft part 18, 20 against one another by means of the lock 22 who pulled. The toggle 32 is now moved in the direction of arrow C. from the rest position 32 'to the actuating position 32 pivoted and then turning the toggle 32 in the direction of arrow A, the distance B between the Holding elements 28 are reduced.
• On toggle 32 is rotated until a comfortable system of the inside shoe on the heel bone in the area of the Achilles tendon is noticeable.
• the surface pressure of the holding elements 28 the heel can be chosen so that a painless, A full feeling of sitting in the Achilles tendon is created.
• the Toggle 32 again in the direction of arrow C in the rest position 32 'pivoted back. It should be noted that the gag 32 pivots into the recess 48 and thus he does not or protrudes only very little beyond the shaft 14.
• the holding elements 28 are on the threaded rod 30 around the Axis 34 can be pivoted to a limited extent (see esp ders in Fig. 1 the distance between the holding element 28 and the inner surface of the rear shaft part 20). This enables a further adaptation of the holding elements 28 on the heel in the area of the Achilles tendon.
• ski boot 10 is the same Holding arrangement 26 as shown in FIG. Identical Parts are given the same reference in the two figures characters indicated. This is only insofar received, as this is necessary for the understanding of the in Fig. 4 shown ski boots 10 is necessary.
• a stiff insole 52 indicated by dashed lines. This is by means of a setting provided in the paragraph area 12 ' device 54 from a lower one shown by dashed lines th position in an upper one shown in dash-dotted lines and with 52 'designated position can be raised or lowered, the Inner sole 52 in the toe area in contact with the inside area of the sole 12 remains. As a result, the distance D between the threaded rod 30 and the insole 52 the dimension d can be reduced.
• the adjustment device 54 has a parallel to the sole 12 and transversely to the longitudinal direction of the shoe 36 (FIG. 2) in the paragraph Area 12 'rotatably mounted adjusting shaft 56 on.
• the position of this adjustment shaft 56 is from the shoe exterior side adjustable. Seated on the adjustment shaft 56 rotatably an eccentric 58 on which the inside Sole 52 is applied. For a foot with a high heel becomes the setting shaft 56 and thus the eccentric disk 58 rotated into the position shown in dashed lines, so that the inner sole 52 is in its lower end position. In the case of a foot with a low heel, the a adjusting shaft 56 rotated by 180 ° so that the inner sole 52 is raised in its upper end position 52 '. Through the Adjustment of the distance D is thus an optimal one Adaptation of the holding arrangement 26 to the foot also in Direction at right angles to the sole 12 reached.
• the holding elements 28 are fastened by means of the threaded rod 30 shifted symmetrically to the middle plane of the shoe (see Fig. 2). It should be noted that but also an asymmetrical Shifting is possible if e.g. the threads 38, 38 ′ are arranged on two separate threaded rods and each a holding element 28 sits on a threaded rod each, from which each individually rotatable by means of a toggle 32 is. It can also be seen that an asymmetrical ver displacement of the holding elements 28 by means of counter-rotating Thread 38, 38 'on the same threaded rod 30 with ver different gradients and with corresponding internal thread the 42, 42 'on the holding elements 28 is possible.
• toggle 32 can be omitted if the mutual distance B between the holding elements 28 for example adjustable by means of an electric motor is. It is also understood that the proposed Holding arrangement 26 in all ski boots, regardless of the Type of shaft and possible entry, use finds application.
