Definitions
- the present invention relates to a cross-country ski provided with an anti-rollback device.
- a wax can be used with which the ski sole is coated and which ensures the attachment of this sole on the snow, when a backward push is exerted on the ski, while reducing friction to a minimum. due to the ski sliding forward.
- Wax is generally the most commonly used anti-rollback method, but it has the disadvantage that its use is delicate and inconvenient: indeed, the waxing operation, which must be carried out before each departure for skiing, takes a certain amount of time, it is difficult to achieve because the wax must be distributed judiciously and moreover the wax must be changed when the quality of the snow varies.
- Cross-country skis of the type known as "scales” are known to date, the soles of which are shaped so as to present, at least in the area of the ski skid, that is to say where the pressure of the foot is exerted. of the skier, a succession of scales distributed, like “fish scales", over at least part of the width and length of the ski and which are slightly projecting from the plane of the sole.
- the scales are arranged in inclined planes from top to bottom and from front to back so as to constitute, at their rear ends, these gripping faces substantially perpendicular to the sole of the ski. Scale skis thus ensure good anchoring of the ski in the snow, during the forward impulse, but they have a major drawback, namely that the protruding scales under the sole considerably increase the friction of this sole on the snow when sliding forward.
- Document US-A-4,398,746 describes an anti-rollback device provided with several anchoring members which are deformed by the horizontal displacement of an adjustment element from a retracted position to a projecting position relative to the plane of the sole.
- the movement of the adjustment element is manually controlled by a handle disposed on the top of the ski.
- the document AT 388302 relates to an anti-kickback device comprising a multitude of ordered scales on a layer of elastomeric material.
- the present invention aims to remedy these drawbacks by providing an anti-rollback device of particularly simple design and making it possible to avoid any penetration of snow into the housing containing the anchoring member.
- this anti-rollback device for cross-country skiing of the type with movable anchor member mounted in a housing formed in the ski and opening into the lower sole thereof, this anchor member being able to occupy, when the ski is subjected to a backward push, a first anchoring position in the snow, in which its lower part projects downwards under the sole of the ski, to be immobilized in the snow or, when the ski slides forward , a second retracted position in which the lower part of the anchoring member is erased in its housing, is characterized inter alia in that the anchoring member has at least one upper face forming a ramp inclined from bottom to top and from front to back, means are provided for keeping the or each upper face forming an inclined ramp of the anchoring member in contact with at least one actuating element provided at the upper part of the housing and for vant sliding longitudinally on the or each upper face forming an inclined ramp, and a longitudinal clearance is provided between the housing and the anchoring member, to allow a slight relative longitudinal movement of the ski and its housing relative to the
- the cross-country ski according to the invention is defined by the technical characteristics mentioned in claim 1.
- FIGS. 1, 1A and 1B is schematically illustrated the principle implemented in the anti-rollback device for cross-country skiing according to the invention.
- a cross-country ski 1 which slides on a layer of snow 2, by its sole 3.
- ski 1 connected to a shoe of the skier, slides from left to right, in the direction of arrow a, as shown in Figure 1, during half of the "alternate step” then it is immobilized on the snow, as shown in Figures 1A and 1B , it serves as a fixed fulcrum, during the other half of the "alternative step", to allow the skier to launch his other ski forward.
- a housing is formed longitudinal 4 which opens into the plane of the sole 3 and which contains the anti-rollback device proper 5.
- This device 5 comprises an anchoring member 6 which, seen in vertical and longitudinal section, has the general shape of a rectangular trapezoid whose the small base is contained in the front end face 6a of the anchoring member 6 and the large base is contained in its rear end face 6b.
- the front front face 6a is normally located at a distance from the front front face 4a of the housing 4 so that a slight longitudinal clearance is provided in the housing 4, in front of the anchoring member 6.
- the rear front face 6b of the anchoring member is, it located against the rear end face 4b of the housing 4 or a short distance from the latter. Therefore the housing 4 has a length slightly greater than that of the anchor member 6. Furthermore the anchor member 6 has a horizontal lower face 6c which is shaped so as to have the best possible adhesion to the surface of the snow layer. This lower horizontal face 6c can be, for example, coated with a piece of seal skin or it can have roughness or suitable roughness.
- the anchoring member 6 also has an upper face 6d which forms a ramp inclined from bottom to top and from front to back, that is to say from right to left in FIGS. 1,1A and 1B .
- This inclined upper ramp 6d cooperates with an actuating element which, in the example shown, is constituted by the inclined upper face 4d delimiting the housing 4 at its upper part and had the same inclination as the ramp 6d.
- Means are provided for keeping the anchoring member 6 applied, by its inclined upper ramp 6d, against the upper face 4d of the housing 4.
- the skier stops his ski 1 and he begins to press on him to allow him to project his other ski in turn forward. It first exerts a vertical downward pressure on the ski 1, as it is represented by the arrow p in FIG. 1A. This has the effect of driving the ski 1 lightly into the snow so that the lower face 6c of the anchoring member 6 comes into contact, under low pressure, with the surface of the snow layer 2 to which it then adheres slightly by friction. The skier then gradually transforms his vertical pressure p into a push P downwards and backwards, as illustrated by the arrow in FIG. 1B.
- This push P gives rise, at the point of contact of the inclined faces 6d of the anchoring member 6 and 4d of the housing 4, to the creation of a horizontal thrust component f directed towards the rear and to a force component f1 directed vertically downwards. Due to the play existing between the front front faces 4a of the housing 4 and 6a of the anchoring member 6, the ski 1 and therefore the housing 4 can move slightly rearward relative to the body anchor 6 kept fixed due to the slight friction of its lower face 6c on snow.
- the inclined upper face 4d of the housing 4 therefore moves slightly backwards relative to the upper inclined ramp 6d of the anchoring member 6 with which it is in contact and this causes a downward movement of the member anchor 6, so that the adherent underside 6c of the anchor member 6 is pressed, under the action of the high pressure due to the vertical force component f1, against the surface of the snow layer 2 Due to its adhesion properties, this lower face 6c immobilizes firmly in the snow 2 and the anchoring member 6 then constitutes a stop engaged and immobilized in the snow.
- the anterior front face 4a of the housing 4 comes to rest against the anterior front face 6a of the anchoring member 6, which is then immobilized firmly, and thus this anchoring member 6 is opposed to any additional movement of the ski 1 towards the rear.
- the skier can thus rest on his ski blocked towards the rear, which allows him to restart his other ski forwards.
- the anchoring member 6 is then released, at its upper part, as a result of the displacement of the inclined upper face 4d of the housing 4 forwards, if although the anchoring member 6 can be raised inside the housing 4, by the return means, to come to occupy its retracted position shown in FIG. 1 in which its lower face 6c is set back relative to the plane of the sole 3 of the ski 1.
- the anti-rollback device comprises an anchoring member 7 which is constituted by a bar elongated in the longitudinal direction, of generally parallelepipedal shape and the lower horizontal face of which is in contact with a flexible and elastic membrane 8 which has , on its underside, adhesion properties vis-à-vis snow and which may be constituted, for example, by a seal skin.
- This flexible membrane 8 extends under the entire length of the bar 7 and it is anchored, by its two end parts 8a and 8b, in the housing 4.
- This anchoring is ensured by wedging the end parts 8a and 8b of the membrane 8 between the rear 4b and anterior 4a front faces of the housing 4, of an art, and two blocks 9 and 11 fixed respectively in the two upper corners of the housing 4, on the other hand.
- the rear corner block 9 is placed against the rear front face 4b of the housing 4, in the upper and rear corner of this housing, and at this point it includes a lower transverse rib 9a which ends in an inclined lower face 9b from bottom to top and back and forth.
- This inclined lower face 9b is situated a little above the plane of the sole of the ski 3 and it is opposite a hollow 12 formed in the central part of the sole 3 of the ski and the upper face of which extends between the sole 3 and the rear front face 4b of the housing, thus being inclined from bottom to top and from back to front.
- the end part 8a of the membrane 8 which is pinched, at its upper part, between the rear front face 4b of the housing 4 and the corner block posterior 9, extends vertically downwards, for a short distance below the inclined lower face 9b, and it bends forward to form the horizontal section of the membrane applied under the anchor bar 7.
- the rear corner block 9 also has, in its front part, a face 9c projecting downwards, which is inclined from bottom to top and from front to back and which constitutes a ramp cooperating with an upper face 7a, having the same inclination, of the longitudinal bar 7.
- This inclined upper face 7a constitutes the lower part of a recess provided in the upper part of the longitudinal bar 7 and in which is engaged the front end part of the rear corner block 9 .
- the longitudinal anchor bar 7 also has, in its upper face, substantially in its middle part, another hollow delimited by an inclined face 7b forming a ramp.
- an intermediate block 13 which is fixed to the upper horizontal face 4d of the housing 4 and which ends in an inclined lower face 13a.
- the inclined faces 7b and 13a which are in contact with each other, have the same inclination as the inclined faces 7a and 9c.
- the front corner block 11 is produced substantially in the same way as the rear corner block 9 and it comprises a lower and front rib 11a which is applied against the front front face 4a of the housing 4, with pinching between them of the anterior extreme part 8b of the membrane 8.
- the anterior corner block 11 also has, in its posterior part, an inclined face 11c projecting downwards which is engaged in a corresponding hollow formed in the anterior part of the upper face of the anchor bar 7, this hollow being delimited by an inclined face 7c.
- the inclined faces 7c and 11c have the same inclination as the other inclined faces cooperating with each other, namely the faces 7a and 9c and the faces 7b and 13a.
- the anti-rollback device also comprises members limiting the admissible vertical downward stroke of the anchor bar 7.
- These members 14 are constituted by vertical rods passing through holes drilled in the anchor bar 7, fixed, at their upper ends, to the upper face 4d of the housing 4 and whose lower ends are integral with the heads 15 arranged in housings 16 provided in the lower horizontal face of the anchor bar 7.
- the housings 16 have a height greater than the thickness of the heads 15 so that the anchor bar 7 can move towards the bottom until the upper bottoms of the housings 16 come into contact with the heads 15 fixed to the lower ends of the rods 14.
- the rear corner block 9, the intermediate block 13 and the front corner block 11 can be constituted by individual blocks fixed by any suitable means to the upper horizontal face 4d of the housing 4. According to a variant, they can be connected to the to each other by constituting a common control bar fixed as a whole to the upper horizontal face 4d of the housing 4. In the latter case, the members 14 limiting the vertical stroke of the anchor bar 7 can advantageously be fixed to this bar. superior common control.
- the anti-rollback device becomes active as shown in FIGS. 3 and 7.
- the inclined lower faces 9c, 13a, 11c of the blocks 9,13 and 11 then slide backwards on the respective inclined ramps 7a, 7b, 7c of the anchor bar 7, which causes displacement of the assembly of this anchor bar 7, parallel to it- even, down.
- This movement is limited by the vertical stop members 14.
- the anchor bar 7 and the seal skin membrane 8 protrude slightly below the plane of the sole 3 of the ski 1, as it is shown in Figures 3 and 7, which ensures the attachment and immobilization of the ski on snow. It should be noted that in this position the posterior end portion 8a of the membrane 8 is stretched and is applied against the underside 9b of the posterior and bottom rib 9a of the posterior corner block 9.
- the elastic membrane 8 acts as a return spring to bring the anchoring bar 7 retracted into the housing 4, when the backward push P is no longer exerted on the ski 1.
- the anti-rollback device comprises a parallelepipedic housing 17 which is tightly fitted and fixed in the housing 4 and which is open at its lower part.
- the housing 17 is fixed inside the housing 4 by any suitable means, for example by gluing or screwing.
- the upper horizontal wall 17a housing 17 has two studs 18 and 19 distant from each other in the longitudinal direction projecting downward and which have, seen in vertical and longitudinal section, the shape of identical right triangles.
- the inclined lower faces 18a, 19a of the studs 18,19 which constitute the hypotheses of the right triangles, are inclined at the same angle from bottom to top and from front to back and they cause the vertical movement of a bar longitudinal anchor 21 of parallelepiped shape, tightly housed in the housing 17.
- This anchor bar 21 has a lower face adapted to obtain good grip on snow, for example by railing, fixing of a seal skin etc. It also has, in its upper surface 21a, two recesses each having, seen in vertical and longitudinal section, the shape of a right triangle and in which the two studs 18,19 are respectively engaged. These recesses are delimited by faces 21b, 21c inclined from bottom to top and from front to back and which are connected to the upper face 21a of the bar 21. The inclined faces 18a and 21b are in contact with one another. other, the inclined faces 19a and 21c are in contact with one another and they all have the same inclination.
- guide means are provided at the two longitudinal ends of the housing 17 and of the anchor bar 21, to allow the vertical movement of the anchor bar 21 downward while guaranteeing a seal towards the interior of the housing. 17.
- the anchor bar 21 is extended by a transverse lip 22 which is inclined from bottom to top and from front to back.
- This lip 22 is engaged in a slot 23 which is formed in the rear transverse wall 17b of the housing 17 and which has the same inclination as the lip 22, as well as the faces 18a, 21b, 19a, 21c.
- the anchor bar 21 In its anterior end portion, the anchor bar 21 has a front face 21d which is inclined from the bottom up and from front to back, with the same inclination angle as the rear lip 22, the slot 23 and the inclined faces. in contact 18a, 21b, 19a, 21c.
- This inclined front end face 21d of the anchor bar 21 is in contact with a face 17c, of the same inclination, provided in the front part of the housing 17.
- the anchor bar 21 has, in its front end part, two opposite lateral ribs 24 which project from the vertical and lateral faces of the anchor bar 21 and which are inclined at the same angle as the faces 21d and 17c. These inclined ribs 24 are engaged in inclined grooves 25 of the same slope which are provided in the anterior parts of the internal faces of the two vertical and lateral walls of the housing 17.
- the anchor bar 21 is retained in the housing 17 and guided relative to the latter on the one hand at its rear end, as a result of the engagement of the rear lip inclined 22 in the inclined slot 23 of the housing 17, and on the other hand at its anterior end, as a result of its inclined lateral ribs 24 engaged in the inclined grooves 25 of the housing 17.
- These guide members provide sealing at the two longitudinal ends of the anti-rollback device and this sealing is also ensured along the lateral faces of the anchor bar 21 and of the housing 17, as a result of the 'narrow fitting of the bar 21 in this housing.
- the anchor bar 21 is freely mounted in the housing 17 and that it is applied under pressure against the snow surface only when a backward thrust is exerted on the ski 1, this thrust being transformed, as in the case of the embodiments previously described, into downward pressure, as a result of the cooperation of the inclined surfaces 18a, 21b, and 19a, 21c.
- Figs. 11a and 11b show an advantageous solution for solving this problem: under the anchoring member 6 a removable plate 63 supporting the anti-recoil system 64 can be quickly put in place and removed.
- the underside of the anchoring member 6 has a recess 61 which serves as a housing for a housing 62 fixed in the recess 61 by any means such as screwing, gluing, welding, etc.
- the removable plate 63 comes to be embedded in the housing 62 and holds in place by friction or snap-fastening. On this removable plate is fixed the anti-recoil system 64 which one wishes to use under the ski.
- skier has several removable plates 63, with on each of them one or more anti-recoil systems to be able to choose at the last moment the system best suited to the circumstances. It is also possible that a removable plate 63 does not have an anti-recoil system on all or part of its surface.
