Description

  

  Appareil d'entraînement     pour    le ski.    L'invention a pour objet un appareil d'en  traînement pour le ski.  



  Cet appareil permet de s'entraîner effi  cacement, en chambre.  



  Le dessin ci-joint en montre, à titre  d'exemple, une forme d'exécution.  



  La     fig.    1 en est une vue en plan, la     fig.    2,  à plus grande échelle, une vue en coupe  transversale, la     fig.    3, une vue partielle lon  gitudinale.  



  Un support rectangulaire est destiné à  reposer sur le sol, il porte les axes verticaux  de poulies 2, 3, 4, 5, 6, 7, et des cloisons  longitudinales 8, 9, 10, ainsi qu'un cadre 11,  12, 13, 14.  



  Contre la poulie 2 passe une courroie 15  dont une extrémité est attachée à l'avant  d'une planche 16, et l'autre extrémité, à  l'avant d'une planche 17, les arrières des  deux planches 16, 17 étant reliés par une  courroie 18 passant contre la poulie 3, de  telle façon que la progression en avant de  l'une des planches commande le retour en  arrière de l'autre. On a indiqué en 19, 20    des organes de fixation des planches aux pieds  du skieur, organes qui peuvent être de tout  dispositif     connu.     



  Les planches 16, 17 reposent sur des  roulettes reposant elles-mêmes sur un fond  21 du support et les cloisons 8, 9, 10 guident  le mouvement que prendront lesdites planches  par l'effort du skieur.  



  Des bâtons 22, 23, représentés rabattus  horizontalement en     fig.    1, sont articulés  chacun sur l'un de deux coulisseaux 24, 25  montés aussi sur roulettes et guidés chacun  par une des cloisons 26, 27 et le cadre du  support.     A,    chacune des cloisons 26, 27, un  rebord 261, 271 empêche le soulèvement des  coulisseaux lorsque les bâtons tirent sur  ceux-ci.  



  Dès courroies 28, 29, 30, 31 passant  contre des poulies 4, 5, 6, 7 sont attachées  aux coulisseaux de telle façon que, comme  le fait comprendre le dessin, chaque coulisseau  soit tenu de prendre un mouvement en sens  contraire de celui de la planche correspon  dante,      L'ensemble de l'appareil permet de faire  un exercice hygiénique et de s'entraîner dans  de bonnes conditions, les pieds du skieur ne  peuvent pas, par exemple, s'écarter davantage  l'un de l'autre, ni prendre diverses inclinai  sons défectueuses.  



  Les dimensions et les détails de construc  tion de l'appareil pourront être modifiés, ainsi  les poulies seront montées de préférence avec  roulement à billes, les courroies ou autres  attaches passant contre les poulies pourront       ê':e    soumises à l'action d'organes tendeurs,  les roulettes pourront se déplacer sur des  rails, et pourraient même être remplacées  par des dispositifs à glissement. Le mouve  ment des planches pourra être ralenti par  des organes de freinage permettant de régler       l'effort    à fournir pour le fonctionnement de  l'appareil.



  Training device for skiing. The object of the invention is a training apparatus for skiing.



  This device allows you to train effectively, in your room.



  The accompanying drawing shows, by way of example, one embodiment.



  Fig. 1 is a plan view thereof, FIG. 2, on a larger scale, a cross-sectional view, FIG. 3, a partial longitudinal view.



  A rectangular support is intended to rest on the ground, it carries the vertical axes of pulleys 2, 3, 4, 5, 6, 7, and longitudinal partitions 8, 9, 10, as well as a frame 11, 12, 13 , 14.



  A belt 15 passes against pulley 2, one end of which is attached to the front of a board 16, and the other end to the front of a board 17, the rear of the two boards 16, 17 being connected by a belt 18 passing against the pulley 3, so that the forward progression of one of the boards controls the backward movement of the other. At 19, 20, members have been indicated for fixing the boards to the skier's feet, members which may be of any known device.



  The boards 16, 17 rest on rollers resting themselves on a base 21 of the support and the partitions 8, 9, 10 guide the movement that said boards will take by the effort of the skier.



  Sticks 22, 23, shown folded horizontally in FIG. 1, are each articulated on one of two slides 24, 25 also mounted on casters and each guided by one of the partitions 26, 27 and the support frame. At each of the partitions 26, 27, a flange 261, 271 prevents the lifting of the slides when the sticks pull on them.



  From belts 28, 29, 30, 31 passing against pulleys 4, 5, 6, 7 are attached to the slides in such a way that, as shown in the drawing, each slide is required to take a movement in the opposite direction to that of the corresponding board, The whole apparatus allows for hygienic exercise and training in good conditions, the skier's feet cannot, for example, deviate further from each other , nor take various defective inclinations.



  The dimensions and construction details of the apparatus may be changed, so the pulleys will preferably be mounted with ball bearings, the belts or other fasteners passing against the pulleys may be subjected to the action of organs. turnbuckles, the rollers can move on rails, and could even be replaced by sliding devices. The movement of the boards may be slowed down by braking members making it possible to adjust the force to be provided for the operation of the apparatus.

Claims

CLAIM Training apparatus for skiing, characterized in that it comprises two boards capable of moving longitudinally on a fixed support, and to each of which one of the skier's feet is intended to be fixed, the movements of these planks being linked to each other by a command such that the forward progression of one requires the reversal of the other. SUB-CLAIMS: 1 Apparatus according to claim, characterized in that the longitudinal movements of the two boards are guided by members which hold them pa rallèles.

2 Apparatus according to claim and sou s-revendicatioii 1, characterized in that it comprises two fasteners each passing against at least one pulley, one of the fasteners being fixed by its ends to the front of the two boards, while the other clip is attached to the back of said boards.

3 Apparatus according to claim and sub-claims 1 and 2, characterized in that it comprises two sticks each articulated on a slide capable of moving parallel to the boards, the movements of the two slides, in the opposite direction one of the the other, being related to the movement of the boards, so that the lower end of a stick is pulled back as the corresponding board progresses forward.

4 Apparatus according to claim and sub-claims 1 to 3. characterized in that the movement of each slide is linked to that, in the opposite direction, of the corresponding board by fasteners passing against at least one pulley. 5 Apparatus according to claim and sub-claims 1 to 4, characterized in that the boards and the sliders of the sticks are mounted on wheels.
