Description

"Intermediate shoe fixation device on a ski"

  The present invention relates to a fixing device

  intermediate shoeing on a ski of the type that allows

  try to ride on a single conventional width ski usually used as a pair, the two boots of a skie next to each other. Various devices of this type are currently known. We know in particular from patent FR 2 514 651 a device

  intermediate of this kind which includes a floor carrying the shoes

  sure and a sole fixed on the ski, floor and sole which are connected by two uprights. This known device has the drawback of being rigid and of being rigidly fixed to the ski. It follows that the ski becomes rigid in its central part and that it loses in large

  partly its qualities of bending and twisting.

  The object of the present invention is in particular to avoid these drawbacks and proposes an intermediate shoe fixing device on a ski of the type comprising a support capable of being fixed on the upper face of a ski and the upper face of which is located at a distance from the upper face of the ski constitutes a platform on which ski boots can be fixed, one next to the other, which is characterized by the fact that it comprises means

  intermediate elastic capable of acting between said support and the ski.

  In this way, the ski carrying the intermediate binding device

  diaire according to the present invention can retain the qualities of

  flexion and torsion which it presents when it carries on its upper face

  directly, only one shoe.

  The intermediate fixing device according to the

  The present invention can have many variant embodiments.

  It may indeed further comprise an intermediate sole on the one hand fixed on said support and on the other hand suitable

  to be fixed on the ski, said intermediate elastic means

  taking at least one elastic element disposed between said sole and

said support.

  It can also have intermediate elastic means comprising elastic elements disposed between at least some of the means for fixing the sole of said support to

the ski and that sole.

  In another variant, it can advantageously comprise an intermediate sole formed by a blade of an elastic material which on the one hand is mounted on said support in two support zones spaced longitudinally and on the other hand is suitable for being fixed on the ski extending on the upper face of the latter, longitudinally, this intermediate sole formed by an elastic material constituting in itself intermediate elastic means

  according to the present invention.

  In this variant, in accordance with the present invention

  tion, said midsole formed of an elastic material is preferably fixed on the ski in two zones located outside

  said longitudinally spaced support zones.

  According to the present invention, an intermediate plate made of an elastic material can advantageously be provided, in at least one of said bearing zones, between said intermediate sole and

said support.

  It may also be advantageous to provide, between the fixing screws, at least one of the fixing areas of the sole.

  intermediate on the ski and this sole, elastic elements.

  According to the present invention, said sole formed by a blade of an elastic material can advantageously extend longitudinally, towards the front and / or towards the rear, extending over

  the upper face of the ski, so that this sole can

  contribute to strengthening the ski which, if it is conventional, must bring to

the weight of the skier alone.

  In this alternative embodiment, it may appear advantageous that at least one of the extensions of the sole formed by a blade made of an elastic material carries a shim.

  disposed between this extension and the ski.

  In another alternative embodiment, this wedge can be carried by a slider adjustable longitudinally along this extension. Thus, the blade made of an elastic material can act on

  the characteristics of the ski in an adjustable way.

  In an alternative embodiment, it is particularly

  rement advantageous that said blade of an elastic material is formed

by a spring steel blade.

  The present invention will be better understood from the study of an intermediate shoe binding device on a ski described by way of non-limiting example and illustrated by the drawing in which: - Figure 1 shows an elevational view of a intermediate binding device according to the present invention mounted on a ski;

  - Figure 2 shows a top view of the arrangement

  intermediate fixing sitive shown in Figure I; - Figure 3 shows an enlarged longitudinal section along III-III of Figure 2, offset from the axis of the ski; - and Figure 4 shows a longitudinal section

  enlarged according to IV-IV of Figure 2.

  The intermediate fastening device shown in the figures and generally identified by the reference I

  is mounted on a conventional ski 2 usually used in pairs.

  This intermediate fixing device comprises a support generally identified by the reference 3 which comprises a platform 4, the upper horizontal face 5 of which is parallel to the upper face 6 of the ski 2 and located at a distance. The support 3 also has a front leg 7 and a rear leg 8 which extend downward from the platform 4 and which are spaced apart in the

  longitudinal direction, these feet having lower end surfaces

  higher 9 and 10 parallel to the upper face 5. As we can -

  see in Figure 3, the support 3 comprises, for example, an envelope 11

  made of synthetic resin reinforced with glass fibers or plastic material

  injected or molded tick, this envelope 11 being filled with foam

made of plastic.

  As can be seen more precisely in FIG. 2, the upper face 5 of the support 3 is substantially rectangular and carries in its front part two front fixings 12 and 13 and in its rear part two rear fixings 14 and 15 which are of a conventional type and which are provided for holding on the platform 4 two ski boots, one next to the other, and located symmetrically with respect to the longitudinal axis of the ski 2. The means of fixing the fasteners 12, 13, 14 and 15 have not been shown in the figures but may be formed, in a conventional manner, by screws, the support 3 possibly also having inserts of

  reinforcement to hold these fixing screws.

  The intermediate binding device 1 also comprises a sole formed by a spring steel blade 16 which extends longitudinally and flat on the upper face 6 of the ski 2,

  below the feet 7 and 8 of the support 3.

  This spring steel blade 16 is fixed to the foot

  front 7 of support 3 thanks to a pair of screws 17 arranged symmetrically

  ment relative to the longitudinal axis of the ski and is fixed to the foot 8 of the support 3 by two pairs of screws 18 and 19 which are also arranged symmetrically with respect to the longitudinal axis of the ski 2, 'the screws 17, 18 and 19 being countersunk heads which are inserted in the

  underside 16a of the spring steel blade 16.

  The spring steel blade 16 is not directly

  resting on the lower faces 8 and 9 of the feet 7 and 8 of the support 3.

  Indeed, there is provided between the upper face 16b of the steel blade

  spring 16 and the lower faces 8 and 9 of the feet 7 and 8 of the upper

  port 3, respectively two plates 20 and 21 which are respectively

  crossed by the screws 17 and 18, 19 and which are made of a plas-

  elastic tick such as an elastomer.

  The width of the spring steel blade 16 is

  slightly less than the width of the ski, the width of the plates

  medials 20 and 21 is substantially equal to the width of the spring steel blade 16, these intermediate plates 20 and 21 covering the surface of the lower faces 9 and 10 of the legs 7 and 8 of the support 3, legs which go, in cross section , flaring upward to

  join the longitudinal edges of the platform 4 of the support 3.

  - Outside the feet 7 and 8 of the support 3, the blade

  made of spring steel 16 is fixed to ski 2, at the front of foot 7 of the support

  port 3 by a pair of screws 22 arranged symmetrically with respect to the longitudinal axis of the ski 2 and at the rear of the foot 8 of the support 3 by

  two pairs of screws 23 and 24 also arranged symmetrically with respect to

  port to the longitudinal axis of the ski. The screws 22, 23 and 24 pass through the spring steel blade 16 and, between their head and the upper face 16b of the spring steel blade 16 are provided respectively compression springs 25, 26 and 27 which could be replaced by Belleville washers or plastic washers

  elastic such as an elastomer. As can be seen in the figure

  re 3, the screws 22 pass through oblong holes 22a which extend long

tudinally.

  Thanks to the structure of the inter-fixing device

  middle 1 described above, we can realize that the spring steel blade 16 can perform, thanks to the elastic intermediate plates 20 and 21 disposed between this blade 16 and the feet 7 and 8 of the support 3, bending movements and / or torsion. In addition, thanks to the springs 25, 26 and 27 provided between the spring steel blade 16 and the fixing screws 22, 23 and 24 of this blade 16 on the ski 2, relative movements of bending and / or torsion can occur between the blade 16 and the ski 2. In addition, like the areas of attachment of the spring steel blade 16 on the ski 2 and on the

  legs 7 and 8 of the support 3 are respectively spaced longitudinally-

  ment, the blade 16 can perform, between these zones, bending and twisting movements. It follows that, even if the support 3 is rigid, the ski 2 can perform relative to this support 3 twisting and / or bending movements substantially as if the ski 2 wore a single shoe in a conventional manner bearing on its upper face 6,

  between two fasteners fixed directly on this upper face 6.

  As can be seen in Figures 1 and 2, the spring steel blade 16 extends largely in front of the foot 7 of the support 3, towards the tip 2a of the ski 2 and behind the foot 8 of the support 3 towards the heel 2b of the ski 2. Thus, the spring steel blade 16

  is supported on the central part of the ski 2 beyond the fixing screws

  tion 22 and 24 and contributes to strengthening the latter which must bear the

total weight of the skier.

  As this spring steel blade 16 is sensitive-

  rectilinear and that ski 2 is arched, there is a growing space

  in thickness between the upper face 6 of the ski 2 and the lower face

  16a of the spring steel blade 16 in the front parts and

  rear of its free extensions front 16c and rear 16d.

  On the front and rear extensions 16c and 16d of the spring steel blade 16 are mounted sliders 28 and 29 which are crossed by this blade 16 and which are longitudinally movable

along the latter.

  Referring to Figure 4, we see that the cur-

  seur 28 has a curved lower part 30 which extends between the upper face 6 of the ski 2 and the lower face 16a of the spring steel blade 16 and that the upper part 31 of this slider 28 carries a screw 32 capable of coming resting on the upper face 16b of the spring steel blade 16 so as to maintain the cursor 28 along the spring steel blade 16. The cursor 29 is constructed from the

same as cursor 28.

  Thanks to these sliders 28 and 29, the spring steel blade 16 acts downwards, by their curved part 30 forming a wedge located between the blade 16 and the ski 2, on the front part and the rear part of the ski 2 also well in its twisting movements that

  in its bending movements. In addition, by adjusting the longi-

  sliders 28 and 29 along the spring steel blade 16, the influence of the spring steel blade 16 can be changed at will

  on the mechanical characteristics of the ski 2.

  The present invention is not limited to the example

  above described. We could indeed have foreseen an intermediate semlle

  diary formed by a blade of another material. We could possibly-

  Lely remove some of the elastic means provided. Many other variant embodiments are possible without departing from the framework defined by

the appended claims.
