SKI ARTICULATED

  The present invention relates to an articulated ski.

  The technical sector of the invention is that of the equipment

to practice snow skiing.

  Skis known as "compact", more manageable and easier to transport than traditional skis and which allow skiers new developments or simply different from those made with conventional skis Like these, the skis

  compacts consist in particular of a pair of pads, however these 10 pads are short.

  We also know monoski which is practiced on a single skate, wider than those of conventional skis or compact skis

  and whose practice is limited to initiated skiers.

  The development of so-called "evolutionary" skiing, the difficulties of using the monoski for the uninitiated and the observation of the uselessness of the outer edges of the traditional skis, are at the origin

  ski according to the present invention.

  The objective to be reached is a ski of a new design accessible to all by its ease of use and its low cost. This object is achieved by the articulated ski according to the invention, which is characterized by the fact that it consists of two runners parallel to each other and lying at rest in the same plane, which skids are connected to each other. other by means of rods hinged to fittings fixed to said pads to allow their relative movement 25 during the evolution of the skier Said rods comprise means

  elastics to bring back to rest or tender bring back during the evolution of the skier, the pads in said plane.

  Said rods extend at rest in the same plane parallel or substantially parallel to the plane of the pads and comprise at their ends and on either side of said fittings, compression springs or blocks of elastic synthetic material subject to

  tare means for adjusting the flexibility of the joints.

  Said fittings are of a straight T-section and comprise a core which extends orthogonally to the pads and through which the rods are passed and perpendicular to this Rme a sole

which is fixed to said pads.

  In one embodiment, said fittings, to which the connecting rods are articulated, are removably mounted in plates attached to the pads and are integral with or released from them by locking means. The sole of each of the brackets is placed in a housing. rectangular parallelepiped reserved in each of said plates, which housing is of a height substantially equal to the thickness of the sole and comprises, on one of its sides and at its upper part, a lip projecting above the housing to hold the sole captive in combination with a lock movable in the plane in which the lip is located and disposed opposite it, which latch is pushed into the locked position by means of a spring. The lock has at its end opposite to that which holds the sole of the fitting in position, an extension in which

  is reserved an eye to facilitate the operation of the lock.

  Said joint fixing plate has in the axis, above the eye of the lock and spaced therefrom, a prolongation extending from the side of the eye of the lock and the end of which comprises a notch which lies substantially in line with the center of the eye, which extension constitutes the point of application of a stick used

  as a lever when opening the lock and whose lower end is passed in said eye.

  The sole of the fittings has a square outline and is placed in a square housing so that the joints can be rotated by 90 and placed in the longitudinal direction of the pads when the

two skates are dissociated.

  Like conventional skis, the skates have a square along their inner edge, but according to the invention, the outer edge of the skates is raised and joins spatulas front and rear.

  The result of the invention is a pair of skis of a new design whose skids are articulated to each other by connecting rods associated with adjustable elastic means which tends to bring the two skids in their position. neutral in the same

plane parallel to the ground.

  Because the joints can be removably mounted, the pads can be used independently of one another

like classic skis.

  Note also that said joints can be mounted on traditional skis equipped with quick couplers according to the invention. The ski according to the invention consists of two front and rear spatula pads without outer edges and connected to each other by means of articulations, the assembly forming a kind of mono-ski of greater freedom. maneuver as the currently known mono-ski and

  The movements of the joints are limited by the springs or the elastic blocks so that the two pads have a limited independence by the adjustment thereof.

  The two pads whose inner edges have edges,

  are spaced from each other to facilitate movement and evacuation of snow.

  In the embodiment o the articulations are removable, these are fixed to the pads by means of a quick coupler

  easy to unlock for example with the tip of a ski pole.

  Because of the design of the joints and their quick attachments, the skier can remove the joints or arrange them on one or the other of the skates in a longitudinal position thus obtaining

a pair of independent skis.

  The combination of the front and rear spatulas and the raised edges of the skis allows the skier to execute free movements such as

  for example one or more turns on itself along a theoretical axis extending from the head to the feet of the skier This design also facilitates the return on the snow in the case of pirouettes.

  The ski according to the invention is used according to the technique of

  parallel skiing known as "scull" and the relative independence of the skates facilitates the practice of skiing and reduces the risk of 25 falls.

  Due to the design of the ski according to the invention whose pads are hinged together elastically, various materials can be used for the manufacture of the pads, which allows

  reduce the cost price of such a ski This being removable, its transport and storage are facilitated.

  Other advantages and characteristics of the invention

  will come out again when reading the following description of a ski

  articulated in non-limiting embodiments and with reference to the drawing in which: Figure 1 is a perspective view of a ski according to the invention in one embodiment o the joint rods which connect the skids are fixed permanently ; FIG. 2 is a partial cross-sectional view of a ski according to the invention in a plane passing through the axis of a connecting rod, in one embodiment where the articulation is removably mounted on the skids ; Figure 3 is a top view of a hinge fixing plate shown in Figure 2; Figure 4 is a longitudinal sectional view of the hinge plate of Figure 3; FIG. 5 is a view from above of a lock constituting the articulation illustrated in FIG. 2; FIG. 6 is a partial top view of the articulation represented in FIG. 2 and illustrating the position relative to the rest of the control eye of the lock relative to the stop fitting which constitutes the point of application of the ski pole to obtain unlocking the joint; Figure 7 is a partial elevational view of a pad that composes the ski according to the invention; FIG. 8 is a front view of one of the front ends

  or rear of a ski according to the invention illustrating the particular shape of the pads whose outer side edges are raised and connected to the spatulas.

  In an embodiment illustrated in Figure 1 of the drawing,

  a ski according to the invention consists of two shoes 1/2, connected to each other by means of rods 3/4, attached to brackets 5/6/7/8.

  The rods 3/4 are parallel to each other and of the same length and are located in the same plane parallel to the pads.

  Each set of support brackets / shank 3/5/6 / -4 / 7/8 is located on either side of the shoe clips 9/10 on the length

skates.

  Since the four support brackets are identical, only the ferrule 30 is described. A support fitting 5 is of a straight T-section and consists of a core 5a and a soleplate 5b. The core 5a is orthogonal to the sole and lies in a plane parallel to the long sides of

  it, which has fixing holes to allow the passage of the clamping screws to the pad, or is secured to said pad by any appropriate means.

  The 5/6/7/8 brackets are two to two distant from the same distance of the shoe fasteners 9/10 The 5/7 and 6/8 fittings, which equip the same shoe 1/2 are aligned with such so that their souls 5a / 7a lie in the same plane parallel to the inner edge / 2a of said pad So the souls are parallel to each other, the soul 5a

  is opposite the soul 6a, the soul 7a is in front of the soul 8a.

  Said cores are pierced to allow the rods 3 to pass therethrough. The rod 3 is passed through reserved holes in the cores a / 6a, the rod 4 into reserved holes in the cores 7a / 8a.

  On either side of each core, the connecting rods comprise resilient means constituted by compression springs or cylindrical blocks made of resilient plastic material subjected to a calibration and whose assembly will be described later with reference to FIG. 2 which illustrates another embodiment of fixing removable brackets.

  Thus connected together by the rods 3/4, the two shoes 1/2 are mounted articulated on the brackets 5/6/7/8 The adjustment 15 of the compression of the springs or cylindrical blocks tends to bring the two skates in their neutral position, that is, in the same

plane parallel to the ground.

  As can be seen in FIG. 1, the shoes 1/2 are of a fairly large width relative to their length and extend parallel to one another and are spaced apart from an "e" space for

  allow a freedom of movement of the two skates and also the evacuation of the snow during the evolution of the skier.

  By way of example, the distance separating the fastenings of the shoes is of the order of fifteen centimeters. Each of the shoes 1/2 comprises a straight internal edge la / 2a, the length of which is fixed, in a known manner, a square 11/12 and a curved and convex outer edge Ib / 2b, which edges are connected to spatulas Ic / 1 d-2 c / 2 d

  which form the ends of the pads.

  According to the invention and as is more particularly illustrated in FIG. 8, the two skids 1/2 comprise a raised edge

  lb / 2b extending outwards and from one spatula lc / 2 d to the other 2 c / 2 d.

  The outer edge has no edge and is preferably rounded.

  Given the relative flexibility of the joints that connect the pads, it is not necessary to pay careful attention to the choice of material for their manufacture as is the case.

  during the manufacture of classic skis.

  The most diverse materials can be used such as wood, plastic, resins reinforced with fiber etc.

  Referring now to Figures 2 to 6 of the drawing.

  Figure 2 is a sectional view of a half-ski according to the invention Only one of the shoes 13 is shown with the connecting means which bind said shoe to the other not shown The ski is symmetrical with respect to the axis XX 1 The rectilinear inner edge 13 has, in known manner, a square edge 14 fixed along the lower angle of the pad, the

  outer edge 13b is raised and has no edge.

  The connecting rod 15 has, at its end 15a, and its

  end 15b (not shown) a coaxial blind hole 15c, which is threaded In this hole 15c is screwed a screw 16 which is passed through a circular hole 17a 1 reserved in the donkey 17a of a fitting - support 17.

  The core 17a is integral with a sole 17b so that the fitting 17 is of a straight section T such as the fittings 5/6/7/8 which have previously been described with reference to FIG. each face of the web 17a and around the hole 17a1 is reserved an annular recess 17a 2/17 to 3 which constitute seats to compression springs 18/19 or to cylindrical blocks made of elastic synthetic material ( not shown) One end of the springs is supported on the seat 17 to 2/17 to 3 and the other on a cup 20/21 The two cups 20/21 are drilled in their center and are traversed by the screw 16 La cup 21 is supported on the end 15a of the rod 15, the other cup 20 bears on the head of the screw 16 The adjustment of the joints is achieved by screwing or unscrewing the screw 16 in the threaded hole 15 c The articulation will be harder when the springs 18/19 are further compressed by acting on the Inversely, the joint will be more flexible if decompressing said springs At rest, the rods 15 and the pads 13 are parallel to each other and the pads are in the neutral position in the same plane l Utrouà pin 15 d allows immobilizer latige 15 The sole 17b of the fitting 17 is of a square section and 30 is placed in a square parallelepiped housing 22a, a height substantially equal to the thickness of the sole and reserved in a rectangular fixing plate 22, which is symmetrical with respect to the median longitudinal axis YY 1 When the fitting 17 is in place in the housing 22a, the axis ZZ 1 of the connecting rod 15 merges with the axis YY 1 of the plate The square parallelepipedal housing comprises above and along its edge 22 to 1 parallel to the narrow sides of the plate 22, a lip 22b projecting from the inside of said housing 22,

  which lip maintains the sole 17b trapped in the housing.

  Above and along the side 22 a 2 opposite to the cé 22a 1 of said housing is mounted movable on the fixing plate 22, a latch 23 which, in extreme "pushed" position overflows above the housing and maintains the sole 17b captive in combination with the lip 22b This latch 23 is shown in plan view in FIG. 5 and consists of a stiffening wing 23a which extends along the length of the beam 22a 2 and a plate 23b intended to move between the fixing plate 22 and a cap 24 fixed to said plate by means of screws passed through

  Circular holes 24a / 22c and through the pad The fixing plate 22 is also fixed to the shoe by means of screws passed through holes 22 d reserved on the side of the lip 22b.

  In the YYI axis of the plate 22 and in the extension of the housing 22 is reserved another rectangular housing 22 e for receiving a spring 25 whose function is to push the latch 23 in its extreme position above the square housing 22a for locking the support bracket 17, which spring bears on an abutment 22f extending perpendicularly to the fixing plate 22 and which penetrates into a housing 24b reserved in the underside of the cap

  24, in which the spring 25 is placed, the housing 24b being complementary to the housing 22 e of the plate 22.

  The plate 23 b of the latch 23 has a rectangular light

  23c in which is placed the compression spring 25.

  The latter, resting on the abutment 22 f, passed through the slot 23c and on the small side 23c 1 thereof, has the effect of pushing the lock over the housing 22a and the sole 17b At its end opposite to that which comprises the stiffening wing 23a, the latch 23 has an extension 23d in which is formed an eye 23e aligned with the longitudinal axis of the light 23c, which eye comprises, at its upper part, a flared entry 23 el to facilitate the passage of the tip 26a of a ski pole 26 shown in phantom lines The cap 24 comprises, above the portion 23d of the bolt 23, an extension 24c extending parallel to the lock 23 and at a distance therefrom, for example thirty-five millimeters. The extension 24c comprises in the median longitudinal axis of the lock and at the right of the eye 35 23 e , a semicircular notch 24 d, whose intersection of its edge and said axis is projected on the center of the eye 23 e (fig 2 and 6) The bottom of the notch 24 d of said extension is the point of application of the ski pole 26, which is used as a lever in the direction of the arrow F to cause the opening of the lock 23 and release the support bracket 17 to separate the two pads, the tip of the stick 26 is engaged in the eye 23 e The fittings 17 and the rods 15 can be removed or be rotated 90 and put in the longitudinal direction of the skates so that the skier can make use of the latter in the manner of traditional skis The pivoting of said fittings is made possible due to the square shape of the soles 17 b
