Description

* * - 1 - clap skate:

Skate where the position of the shoe (and foot) can change in relation to the tube (incl. Steel).

The invention relates to a construction which achieves a fundamental improvement of the sales in skating. This applies not only to sales on continuous skates (wooden skates, noren) but also for figure skates, hokey skates and even roller skates.

In more technical terms, the invention can be described as follows:

In contrast to all existing skates in a general sense, a construction has been made which makes it possible to bend the human foot in the appropriate place (the metatarsophalangeal joint), such as is the case when walking, jumping and cross-country skiing, without the sliding process. influence (so-called punting becomes impossible). The iron (the tube) maintains a horizontal position while the foot can be brought into extensive plantar flexion. The need to "sit on the back of the skate" is eliminated.

The skates nevertheless retain the necessary transverse stiffness · The bend in the forefoot gives the outstanding advantage that, unlike the current skating process, the push-off leg can be fully stretched.

The ability to stretch the marketing leg makes it possible to use important muscle groups of the lower and upper leg that are not used for the supply of labor in the existing skating process, with the advantage of availability of more power and a more natural course of skating .

In a constructive sense, several solutions are possible, provided that the construction causes the flexion of the foot to take place in an anatomically responsible manner and the stiffness of the foot with respect to skate iron (tube). transverse direction is maintained.

The invention will be explained in more detail with reference to the drawings in which an exemplary embodiment is presented:

Fig. 3 shows the clap skate in the unlocked position, hst three-five-way hinge A.8.C practically fully opened, the skate boot bent above the front skate spot 10. This position is reached at the end of the push-off.

Fig. 4 shows an enlarged view of the three-prong hinge A.8.C. consisting of parts 2.3.4 and 5 rotating about the parallel-10 hinge pins in A, B and C.

Fig. 5 shows the chopping of the clap skate in the rest position or the sliding position but unblocked, effected by pulling the catch 7 up by the cord 9, which can be effected by pulling the cord 9 on the freely selectable moment by pulling the cord 9. Osz's blocking option has been added to enable the usual starting technique to be carried out.

The clap skate according to the invention consists of the movable contact of the shoe 1 relative to the tube 2, the point of inflection of the shoe relative to the tube 2 being located at the height of the front skate spot 10, such that the foot inserted into shoe 1 can bend naturally in the so-called metatarsophalangeal joint. /

In order to obtain the transverse stiffness of the shoe 1 coupled to the skate iron 2 necessary for the skating process, a three-part hinge A.8.C has been constructed.

Hinge point A is connected to hinge point 8 by a reinforced plate profile 5, this is connected to hinge point C with a reinforced plate profile 4, hinge point C is attached to the heel plate 3, the heel plate 3 is attached to the shoe 1, hinge-30 point A is In the skate iron 2 bearings.

The design of part 4 and part 5, respectively, is such that in the closed position of the three-way hinge A.8.C a bounce is created on the correct position of the foot in the sliding phase for the skating process. When shoe 1 is bent, part 4 will turn counterclockwise and part 5 will turn clockwise. This rotary movement ends when the pivot points A, 8 and C are almost aligned; In order to avoid blocking in the maximum open position ta-BAftORIfillAM, the evenness of part 5 is limited. A smooth return to the closed position of the hinge construction is obtained by the spring 8 which will be tensioned when bending the shoe 1 with respect to the skate iron 2.

The hinges A, B and C are provided with a self-lubricating plastic bearing. The 5 parts 4 and 5 made of sheet steel in box construction in combination with the hinges A, B and C provide ample transverse stiffness.

The shoe 1 is designed in such a way that smooth bending in point 10 is obtained but has sufficient longitudinal stiffness.

In a special embodiment, especially for the first strokes at the start during competitions, the construction is designed in such a way that the shoe 1 can be blocked with the skate iron 2 in the rest position or in the sliding position as with existing skates. This block (Fig. 2) is created with parts 6 and 7, part 6 is hinged around A and can be hooked with a lip, over part 4, 15 part 7 in turn catches part 6. The block can be released by pulling part 7 counterclockwise with pull cord 9 from part 6. Part 6 escapes from part 4 turning clockwise at A, for which the hairpin spring 6a takes care of. Fig. 5 shows the final unblocked state. The release can be operated remotely with the right and left hand at any time.

After sufficient training on this new skating technique, this blocking option will become superfluous.

In particular, the essential feature of the invention concerns the created possibility of a dorsal flexion of the foot in the netatarsophalangeal joint, allowing for a great plantar flexion (stretch) of the ankle.

Claims (3)

1. Clap skates to improve the existing skating process by making more efficient use of the available muscle groups during skating. In particular to achieve a more natural course of the skating process and of the overall movement pattern. Publications on the functional anatomy of the human legs leave no doubt about the efficiency of the musculoskeletal system with maximum stretching of the legs. Because an extension of the foot (plantar flexion) is omitted from existing skates, it appears that not only can the calf muscles provide little work, but in addition it is in principle impossible to fully stretch the knee during the push-off. (The speed between hip and ankle becomes zero when the knee 180 ° is reached). When running, jumping etc *, a further increase in speed of the trunk 15 is achieved by also stretching the ankle halfway through the extension of the knee. In this way, both the knee joint stretchers and the ankle joint stretchers can continue to shorten and provide labor until the extremities in the joints are reached. This is now also possible with these new skates during 20 skates. It can be deduced from energy consumption measurements during running and skating that in this way it must be possible to increase the total power output of a skater by about 10-20 $. / 2. The new skates have a hinge construction with the bending point under the ball of the foot. To maintain the stiffness of the skate blades transversely to the foot, a three-way hinge is used, which is located under the heel of the foot. The correct gliding position of the foot with respect to * the skating iron can be maintained by a bounce. From the foregoing description it may become apparent that the invention is not characterized by the final construction but by the possibility of bending the foot relative to the tube of the skate, so that during the marketing phase of the skating process the marketing can be continued until marketing leg is almost straight. The described construction fully meets the requirements imposed on the natural course of the marketing process. The extra possibility to temporarily fix the shoe in relation to the tube makes it possible to choose the starting technique as is currently customary in the skating competition sport.
