Abstract

The present invention relates to cross-country skis. The ski 1 is provided with a pendulum which is displaced along the guide 4. The system for the magnetic binding of the boots is mounted on a horizontally sliding plate 9. This permits extension of the time during which the skis are at a "dead point" and recovery of the skier's energy. A small zone 15 of the lower surface of the skis is covered with bristles 33. For binding the boots, a magnetic plate is placed on the binding plate 9; in this case, it is necessary to place an iron plate on the boot soles.

Description

La présente invention concerne les skis de fond. The present invention relates to cross-country skis.

Afin d'économiser l'énergie du skieur, il est proposé de récupérer au maximum l'énergie du mouvement oscillatoire des skis, des pieds et des bâtons. Pour ce faire:
1. Le ski (I) est pourvu d'un pendule se déplaçant le long du guide (4). Le pendule (5) peut être solide ou liquide (p.ex. du mercure contenu entre les soupapes 25 et 27). Le guide (4) est fixé sur le ski (I) à l'aide de supports (2, 7). Le guide (4, 30) peut se fixer sur le ski ou à l'intérieur du ski.
In order to save the energy of the skier, it is proposed to recover as much energy as possible from the oscillatory movement of skis, feet and poles. To do this:
1. The ski (I) is provided with a pendulum moving along the guide (4). The pendulum (5) can be solid or liquid (eg mercury contained between valves 25 and 27). The guide (4) is fixed to the ski (I) using supports (2, 7). The guide (4, 30) can be fixed on the ski or inside the ski.

Le mouvement du pendule est limité par des dampers: à ressort (3, 6) ou à air (23, 29). Le pas de damper (3, 6; 23, 29) (sous l'action du pendule 5 ou 26) est limité par des appuis (21, 22; 24,28).The pendulum movement is limited by dampers: spring (3, 6) or air (23, 29). The damper pitch (3, 6; 23, 29) (under the action of the pendulum 5 or 26) is limited by supports (21, 22; 24,28).

L'emplacement des appuis (21, 22, 24, 28), la masse du pendule (5, 26) et les coefficients d'élasticité des dampers (3, 6, 23, 29) sont choisi en fonttion des paramètres psycho-physiques du skieur.The location of the supports (21, 22, 24, 28), the mass of the pendulum (5, 26) and the elasticity coefficients of the dampers (3, 6, 23, 29) are chosen according to the psycho-physical parameters of the skier.

La technique de marche sur les skis à pendule. Soit au départ le ski se trouve dans un point mort et le ressort (3) a repoussé le pendule (5) en avant (à droite). Juste après le ski est amene en avant, en suivant le pendule. Si le mouvement du ski est ralenti, le pendule (5) passe en avant et appuie sur le ressort (6), en donnant sa quantité de mouvement au ski, et donc au skieur. Ensuite le pendule (5) va dans le sens opposé jusqu'au ressort (4) et freine le ski pour l'arrêter. Après l'arrêt du ski et le passage du pendule en avant (sous l'action du ressort 4), le cycle décrit ci-dessus se répète. The walking technique on pendulum skis. Either at the start the ski is in a neutral position and the spring (3) has pushed the pendulum (5) forward (right). Right after the ski is brought forward, following the pendulum. If the movement of the ski is slowed down, the pendulum (5) goes forward and presses on the spring (6), giving its amount of movement to the ski, and therefore to the skier. Then the pendulum (5) goes in the opposite direction to the spring (4) and brakes the ski to stop it. After the ski has stopped and the pendulum has passed forward (under the action of spring 4), the cycle described above is repeated.

2. Tout le système de fixation des chaussures est monté sur une plaque (9) glissant sur les guides (10). Le pas de la plaque est limité par des appuis (31, 32). A l'aide des ressorts (11) la plaque est déplacée dans la position avant. Au début du repoussement par le pied la plaque "a en arrière; à la fin du repoussement le ressort (11) tire la plaque (9) (donc aussi le pied du skieur) en avant, en augmentant la force du repoussement du pied. 2. The entire shoe fastening system is mounted on a plate (9) sliding on the guides (10). The pitch of the plate is limited by supports (31, 32). Using the springs (11) the plate is moved to the front position. At the beginning of the pushing back by the foot the plate "has backward; at the end of the pushing back the spring (11) pulls the plate (9) (therefore also the skier's foot) forward, increasing the force of the pushing back of the foot.

3. Le talon de la chaussure du skieur se pose sur un ressort plat (8). Le ressort ne prend la position horizontale que lors un effort égal au poids du skieur. 3. The heel of the skier's shoe rests on a flat spring (8). The spring only takes the horizontal position when an effort is equal to the weight of the skier.

4. Le manche (17) ou la base (i4) des anneaux des barons de skis est pourvu de ressorts (18, 35).  4. The handle (17) or the base (i4) of the rings of the ski barons is provided with springs (18, 35).

Le pas des ressorts est limité par des appuis (16, 19, 36; 37).The pitch of the springs is limited by supports (16, 19, 36; 37).

Il est connu que pour arrêter le glissement des skis en arrière, la surface inférieure des ski est couverte de poils, ce qui altère les propriété de glissement de. la surface. Nous proposons donc de laisser des poils uniquement dans deux endroits: sous le pieds et sur la spatule. En plus, on propose d'utiliser à ces fins des poils sythétiques, solides et élastiques. Les poils sous les pieds sont mis dans la courbure de sorte que pendant une marche dans un endroit plat, les poils ne dépassent pas la surface de glisse des skis. It is known that to stop the sliding of the skis backwards, the lower surface of the skis is covered with hairs, which alters the sliding properties of. the surface. We therefore suggest leaving hair only in two places: under the feet and on the spatula. In addition, it is proposed to use for these purposes synthetic, solid and elastic bristles. The hairs under the feet are put in the curvature so that when walking in a flat place, the hairs do not exceed the sliding surface of the skis.

Pour la fixation des chaussures il est recommandé de poser une plaque magnétique en relief (38) sur la plaque (9) de fixation; dans ce cas il faut poser une plaque en fer (39) sur les semelles des chaussures avec le relief correspondant. De bonnes qualités aurait un relief trapézoïde (en section).  For fixing the shoes it is recommended to place a raised magnetic plate (38) on the fixing plate (9); in this case, an iron plate (39) must be placed on the soles of the shoes with the corresponding relief. Good qualities would have a trapezoid relief (in section).
