SI20715A - Touring boot with a cuff - Google Patents

Abstract

The invention concerns the touring boot with cuff which offers side support to the ankle and enables the motion of the ankle in the direction back and forth and in which the axis of rotation with respect to the longitudinal axis of the boot is moved outwards. The outer pivot (4) that connects the cuff (1) with the collar (2) is moved backwards while the inner pivot (3) of the cuff (1) is moved forwards so that the axis of rotation (5) of the cuff (1) is perpendicular to the longitudinal axis (6) of the boot.

Description

SKI COUNTER SHOE WITH LOCKED COVER

The subject of the invention is a ski running shoe with a cuff, which provides a lateral ankle support 15 and allows the ankle to be moved back and forth in which the axis of rotation is offset with respect to the longitudinal axis of the shoe.

The invention belongs to Class A 43B 5/04 of the International Patent Classification.

A technical problem solved by the present invention is how to perform a ski running shoe, which will allow the ski to be placed on the inner edge as easily as possible before and during the skating, and thus the best skating in the skating technique.

The first cross-country ski boots were made only for the classic cross-country skiing technique, where the lateral stability of the shoe does not matter, so that these boots did not have a cuff at all. With the advent of skating technique, there was a need for greater lateral stability of the ski running shoe, which is important especially in the off-stage. The lateral stability was improved by the use of a plastic cuff that provides a lateral support to the ankle, but at the same time does not impede the movement of the ankle in a forward or backward direction. With all known solutions, the axis of rotation of the cuff is perpendicular to the longitudinal axis of the ski running shoe and the ski, which causes the cuff to move in a forward and backward direction parallel to the longitudinal axis of the ski. A careful study of the skating technique of cross-country skiing reveals that the leg of the cross-country skier does not move parallel to the longitudinal axis of the ski from the ankle upwards - backwards. As the runner prepares to pull off, the leg moves upwards from the ankle, and the foot in the ankle rotates inward to adjust the ski to the edge, which is necessary to grip the ski when lifting. As a result, the ankle leg moves outwards relative to the longitudinal axis of the ski. Since the rotation axis of the cuff is perpendicular to the longitudinal axis of the ski in all known solutions and moves in a forward direction parallel to the longitudinal axis of the ski and the leg of the skier of the runner moves forward and outwards, the skier needs to deform the shoe in order to make the necessary adjustment movement. skis to the edge.

According to the invention, the described technical problem is solved by shifting the outer (right on the right shoe and left on the left shoe) back of the cuff and the internal hinge forward. As a result, the axis of rotation of the cuff is no longer perpendicular to the longitudinal axis of the shoe and the longitudinal axis of the ski, but is offset. The direction of movement of the cuff is not parallel to the longitudinal axis of the shoe, but moves in a forward, outward - backward, inward direction, which is also the direction of movement of the skier's leg of the runner from the ankle upwards. As a result, the skier does not need to deform the shoe to make the necessary movement to adjust the ski to the edge, but the shoe allows him to perform this movement freely. This saves the competitor the energy they previously used to deform the ski running shoe.

The invention is explained in more detail by way of a description of an embodiment and accompanying drawings showing:

Fig. 1 is a top view of the right ski running shoe; figure 2 side view on the right ski running shoe.

The cross-country ski boot with the offset cuff according to the invention is shown in Figures 1 and 2. The cuff 1 is attached to the heel 2 of the ski boot with the inner hinge 3 and the outer hinge 4. Through the inner hinge 3 and the outer hinge 4, the shaft 5 rotates axis 5. The longitudinal axis 6 of the ski running shoe is parallel to the longitudinal axis of the ski when the shoe is mounted on the ski. The hinges 3 and 4 on the repeater 2 are in such a position that the axis 5 rotates

The 2o of the cuff 1 is not perpendicular to the longitudinal axis 6 of the ski running shoe, but is rotated clockwise with the right shoe and counterclockwise with the left shoe. The angle between the rectangle 8 on the longitudinal axis 6 of the shoe and the axis 5 of rotation of the cuff 1 is between 1 ° and 20 °.

The skier moves the leg 7 upwards from the ankle during the preparation phase. The foot portion rotates around the longitudinal axis 6 of the foot inward to place the ski on the inside edge, which is necessary to grip the ski in the stripping phase. Both movements are made at the same time. The combination of both movements is the movement of the leg 7 in a forward and outward direction relative to the ski. The axis of rotation 5 of the cuff 1 due to the rotated position relative to the perpendicular 8 to the longitudinal axis 6 of the shoe allows the runner an unrestricted performance of the aforementioned combination of movements, or assists the skipper in performing a good offset of optimum movement.
