Definitions
- the present invention relates to a ski binding, more specifically of the telemark type. Nevertheless, it finds its application in bindings fitted in other types of skis, such as cross-country skis, that the user wishes to use in “telemark” mode.
- ski touring, telemark or cross-country ski bindings enable easy lifting of the heel in practice either for climbing or to make telemark steps to make a turn. To be able to make this move, the bindings hold the toe of the boot by means of a toe piece leaving the heel free to move.
- bindings In telemark skiing, the most commonly used equipment was bindings according to the “75 standard” such as for example the bindings described in U.S. Pat. No. 7,401,802 (Black Diamond Equipment).
- This type of binding is characterized by a fixed front binding, which maintains the so-called “duckbill” shape located at the front of the boot, as well as a cable tension system equipped with springs locking on the heel of the boot.
- the standard of these bindings requires a right binding and a left binding. Indeed, the shape of the soles is asymmetrical, with a more outwardly flared shape of the foot. However, it is possible to place a right boot in a left binding; as a result, the ski will not be aligned with the boot effectively making it considerably difficult to ski.
- This boot standard also makes it difficult to walk on rocks when climbing up a mountain. It does not allow the use of standard ice cleats and limits the use of this type of boot solely to skis with telemark bindings. Besides the right and left binding problem, it is always very difficult to fit the boots in the bindings. The skier is frequently obliged to place one knee on the ground to immobilize the ski and be able to lock the tension system on the heel of the boot. These operations are made even more difficult, in the presence of snow. Indeed, as skis are rarely equipped with “ski stops”, they slip easily sometimes making the locking operation tedious. Finally, boot removal in the case of a fall is practically impossible, such that the use of these bindings therefore involves a high risk of injury for skiers.
- NTN New Telemark Norm
- the new boots defined by this standard, can be used for telemark or alpine skiing, and can receive standard ice cleats.
- the sole of the boot is divided into two parts: the front sole specific to the NTN standard and the heel which is conventional and separate from the front sole.
- the specificity of the front sole stems from the projection (NTN attachment zone) which is located at the level of the arch of the foot at the center of the boot, at the rear end of the front sole.
- NTN attachment zone which is located at the level of the arch of the foot at the center of the boot, at the rear end of the front sole.
- the sole is also symmetrical.
- bindings which combine the freedom of movement of the heel specific to telemark skiing and which incorporate a safety device releasing the boot if the skier falls.
- the bindings are symmetrical, the user can put on the ski that they wish as they would for conventional alpine ski bindings, there is no longer any left or right ski.
- these bindings can also incorporate ski stops and provide extra safety for skiers.
- binding comprises an assembly for immobilizing the front end of the boot, which particularly includes a toe piece.
- This toe piece in the shape of a horseshoe, holds the front of the boot and the lateral overhangs ensuring a satisfactory hold of the boot.
- the boot is kept flat along the front 40 millimeters of the boot. Therefore, the first 30 millimeters of the shell of the boot are also kept flat by the toe piece which exerts the holding function thereof on the lateral overhangs of the sole.
- the front immobilization assembly cited above is locked in rotation with respect to the ski.
- the front part of the boot is kept flat, parallel with the ski.
- the toe piece being locked in rotation the boot is constrained when the heel is lifted. It is firstly observed that, when practicing Telemark skiing, the sole of the boot is considerably damaged. On lifting the heel, when the gusset is fully compressed, the area of the boot located between the front of the gusset and the portion held by the toe piece is deformed as the portion of the sole located immediately above is locked in the toe piece. The lateral overhangs of the boots are marked considerably and sometimes tear. After a few months of use, the boot is irremediably deformed and substantial play between the boot and the binding appears, introducing a floating sensation which limits ski control precision.
- this binding does not offer progressive flexion for the user seeking to practice Telemark skiing. In particular, during certain flexural movement phases completed by the user, this flexion is not perceived as regular, varies considerably sometimes with play and moments without tension.
- This binding offers an additional mode of use, of ski touring type, wherein this front immobilizing assembly is freed, so as to be able to pivot with respect to the ski about a transverse axis located under the front portion of the sole of the boot. Therefore, in telemark mode, the toe piece is locked whereas in ski touring mode, the toe piece is free to rotate.
- the type of bindings involves numerous drawbacks, particularly deformation and wear of the boots due to the stress created by the new geometry of the toe piece as well as the high levels of stress in the binding.
- Bindings complying with the NTN standard are known, which are marketed by the company 22DESIGN under the reference OUTLAWTM.
- This binding uses a short toe piece with little engagement of the sole. Only the first 10 millimeters of the sole are engaged in the toe piece. The lateral overhangs of the sole not being held.
- This choice allows a certain degree of rotation of the boot within this toe piece. Accordingly, the locking sensation is reduced, particularly with regard to the solution described immediately above.
- this reduction in length of the toe piece gives rise to significant risks of the boot coming out of this toe piece. This also results in less precision during edging when the user wishes to take a bend. Indeed, as the overhangs of the sole are not used, the lateral load transmission is reduced.
- the aim of the present invention is that of remedying at least some drawbacks of the prior art mentioned above.
- the introduction of the NTN standard has divided the telemark community, as the products proposed required a change of technique.
- the applicant introduced a new product names MEIDJOTM onto the market which, while using boots conforming to the NTN standard, makes it possible to regain the sensations of conventional so-called “75 norm” bindings.
- the present invention proposes first of all to offer the same convenience of use.
- the aim of the present invention is also that of proposing a binding which makes it possible to reduce mechanical stress, when practicing Telemark skiing.
- the aim of the present invention is also that of proposing such a binding, which prevents any untimely wear of the boot.
- the aim of the present invention is also that of proposing such a binding, which ensures pleasant practice of Telemark skiing for the user, particularly by allowing the most natural leg flexion possible with regular and progressive tension.
- the aim of the present invention is also that of proposing such a binding, which enables boot fitting that is particularly simple and quick to carry out.
- the aim of the invention is that of proposing such a binding which is capable of incorporating, on the front part thereof, a safety system with a view to boot removal.
- This invention relates to a binding wherein the front assembly (referenced 3 in appended FIG. 1 ) is mounted in a floating manner and free to rotate on an axis (referenced A 3 in FIG. 1 ) perpendicular to the skier's direction of natural movement, ideally positioned just in front of the boot.
- This floating front assembly associated with a suitable tension system (formed by references 6 and 66 in the appended figures), making it possible to create an adapted triangle of forces, offers the user flexion with regular and progressive holding tension, without excessive stress on the equipment.
- This invention therefore limits the internal forces in the system without constraining the boot excessively.
- the effect of the floating front assembly with a pivot point ideally placed just in front of the boot makes it possible to obtain two phases of optimal use for the user:
- the front immobilization assembly ( 3 , 103 ; 203 ) is mounted in a floating manner on the front plate, about a transverse pivot axis (A 3 ; A 103 ; A 203 ) located, viewed longitudinally, in front of a so-called supporting point ( 32 ′) belonging to the front assembly, said supporting point enabling the front end ( 81 ′) of the sole ( 81 ; 281 ) of the boot to be supported,
- the binding according to the invention can comprise all or some of the following features, insofar as they are technically compatible:
- the invention also relates to a method for adjusting a ski binding ( 1 ; 101 ; 201 ), in particular a ski touring, telemark or cross-country ski binding, for binding a ski boot ( 8 ; 208 ), including a sole ( 81 ; 281 ) and a heel ( 84 ; 284 ), said ski binding ( 1 ) comprising:
- this method being characterized in that the front immobilization assembly ( 3 , 103 ; 203 ) is mounted in a floating manner on the front plate, about a transverse pivot axis (A 3 ; A 103 ; A 203 ),
- the hinged axis (A 6 ) of the rear retaining assembly ( 6 ; 106 ; 206 ), with respect to the front plate ( 2 , 102 ; 202 ), is distinct from the transverse pivot axis (A 3 ), this hinged axis (A 6 ) of the rear retaining assembly ( 6 ; 106 ) being located to the rear, with reference to the direction of movement of the ski, of this transverse pivot axis,
- the tensioning means are adjusted such that, in a first flexion phase, the front immobilization assembly ( 3 , 103 ; 203 ) does not pivot substantially and, in a second greater boot flexion phase, this front immobilization assembly ( 3 , 103 ; 203 ) pivots with respect to the plate.
- the distance (L 36 ) separating, along a longitudinal direction, the transverse pivot axis (A 3 ) and the hinged axis (A 6 ) of the rear retaining assembly is furthermore adjusted.
- the invention finally relates to a ski comprising a binding ( 1 ) as above.
- the immobilization assembly is mounted in a floating manner.
- the pivoting of this assembly with respect to the ski is entirely free, i.e. the invention avoids the use of a locking member as described in EP 1 790 396.
- this floating and rotatable property makes it possible to substantially reduce the stress exerted on the binding according to the invention, as well as on the shoe immobilized in this binding.
- the stress associated with the tilting torque at the front zone of the boot is reduced, given that the boot can tilt when the toe piece is subject to substantial stress. Under these conditions, the service life both of the binding and the boot is enhanced.
- the floating property described above is not accompanied by instability, which would be detrimental to the satisfactory use of the binding.
- the pivot axis of the immobilization assembly, with respect to the front plate is positioned judiciously.
- a person skilled in the art would be able to adjust certain dimensional parameters which will be detailed hereinafter.
- the user's weight induces natural downward tilting of the toe of the boot, in the opposite direction of this flexion.
- the immobilization assembly is substantially fixed whereas the front of the shoe is kept flat, in a stable manner.
- the immobilization assembly is then moved, during a more accentuated phase of this flexion, so as to follow the pivoting of the boot.
- the overall flexural movement is therefore carried out particularly naturally, which is very pleasant for the user.
- FIG. 1 which is the basis of the teaching of WO 96/23558, describes a binding concept wherein the boot is held by the toe and a protuberance located under the sole, as well as a tension system connecting these two zones. It should be noted that the tension system is connected to the toe piece which holds the toe of the boot by means of an axis numbered 23 in this figure. A person skilled in the art would readily understand that this concept may indeed work in theory, but only on one condition: the toe piece must be locked or significantly restricted in rotation.

- the supporting member 3 and the toe piece 40 are rigidly connected by the axes 39 .
- the latch 50 is in the active position thereof, such that the support member 3 and the toe piece 40 are immobilized in rotation, as explained above.
- the user then exerts an action on the tensioning rod, mentioned above, so as move the nose 64 away from the rods 62 .
- This nose 64 is then coupled to a retaining lug 85 , particularly seen in FIG. 4 , belonging to this boot.
- this lug 85 is provided at the rear end of the front zone of the boot.
- this lug 85 can be placed at the rear end 84 of this boot.
- the user can then practice Telemark skiing, particularly by means of flexion of the inner leg against the tensioning means 66 .
- the user tends to compress or “break” a gusset 86 , provided in the front portion of the boot and clearly visible in FIG. 20 .
- a so-called angle of flexion aF is defined, which is formed between the horizontal and the principal plane P 60 of the base 60 of the retaining element 6 .
- a first flexion phase corresponding to a low value of the angle of flexion (for example 30° in FIG. 7 )
- the immobilization assembly 3 does not pivot substantially with respect to the plate 2 , even if this assembly is mounted in a floating manner as explained above.
- the immobilization assembly 3 forms an angle, annotated a 3 in FIG. 8 , which is less than 3° (in the drawing this angle is close to ⁇ 7°). Accordingly, the front of the boot is kept flat. On the other hand, the rear of the boot is raised, by means of compression of the gusset 86 .
- the immobilization assembly 3 pivots with respect to the plate 2 according to the arrow F 3 , as shown in FIG. 8 .
- This pivoting is obtained beyond a threshold value of the angle of flexion, which is for example close to 40°.
- this angle of flexion has a value of close to 80°.
- the immobilization assembly 3 forms a significant angle ⁇ 3 , with respect to the initial position thereof, typically greater than 10°.
- FIG. 4 illustrates the zone wherein this axis can be positioned.
- the boot 8 is featured, wherein the vamp bears against the edge 43 ′.
- the lug 83 abuts against the seat 36
- the front end 81 ′ of the sole bears against the so-called characteristic point 32 ′ belonging to the plate 32 .
- the zone Z 3 represented overall by a rectangle in this FIG. 4 , illustrates the different possibilities with a view to the positioning of the axis A 3 .
- this axis is placed immediately in front of the seat 36 , namely immediately facing the lug 83 . This means that the distance between this seat 36 and this axis A 3 is very small, typically less than 3 millimeters.
- X 3 is less than 40 mm millimeters, preferably than 25 millimeters.
- a 3 is located in front of the point 32 ′ along a distance less than 16 mm.
- Y 3 is between ⁇ 30 millimeters and +30 millimeters with respect to the point 32 ′, in which case the axis A 3 is positioned vertically more or less above or below the sole of the boot.
- the axis A 3 is positioned facing the sole with a value of Y 3 equal to +8 millimeters, namely that this axis is positioned slightly above this point 32 ′.
- the axis A 3 is placed below the characteristic point, therefore vertically below the sole plane, this makes it possible to free a space, wherein an additional mechanical system, particularly a safety boot removal system of any suitable type, can be provided.
- the axis A 3 is located in front of the seat of the toe piece, helping support the lug 83 . Nevertheless, it can be envisaged that this axis extends further forward, namely in the vicinity of the supporting point 32 ′. In this latter case, this axis extends through the lug 83 , i.e. it consists of a geometric axis, but not a physical axis. Suitable means are then provided, enabling the pivoting about this purely geometric, or virtual, axis. These means can be for example return means, such as connecting rods or external pivots placed in the flanks 24 , whereon the assembly 3 pivots.
- the distance L 36 separating along the longitudinal axis the pivot point A 3 and the hinge point A 6 of the rear retaining assembly 6 is noted.
- the axis A 3 is located in front of the axis A 6 so as to form a triangle of forces formed by these two axes and by the user's heel, which induces a tilting of the shoe.
- This distance is advantageously between 20 and 120 millimeters, being preferably between 35 and 80 millimeters. In this way, the triangle of forces mentioned above provides particularly satisfactory tilting of this boot.
- the user can then exert an upward action, so as to pivot the toe piece along the arrow F 40 in FIG. 19 .
- this action is carried out by means of the washer of the stick.

Description
- The present invention relates to a ski binding, more specifically of the telemark type. Nevertheless, it finds its application in bindings fitted in other types of skis, such as cross-country skis, that the user wishes to use in “telemark” mode.
- Traditionally ski touring, telemark or cross-country ski bindings enable easy lifting of the heel in practice either for climbing or to make telemark steps to make a turn. To be able to make this move, the bindings hold the toe of the boot by means of a toe piece leaving the heel free to move.
- In telemark skiing, the most commonly used equipment was bindings according to the “75 standard” such as for example the bindings described in U.S. Pat. No. 7,401,802 (Black Diamond Equipment). This type of binding is characterized by a fixed front binding, which maintains the so-called “duckbill” shape located at the front of the boot, as well as a cable tension system equipped with springs locking on the heel of the boot. The standard of these bindings requires a right binding and a left binding. Indeed, the shape of the soles is asymmetrical, with a more outwardly flared shape of the foot. However, it is possible to place a right boot in a left binding; as a result, the ski will not be aligned with the boot effectively making it considerably difficult to ski.
- This boot standard also makes it difficult to walk on rocks when climbing up a mountain. It does not allow the use of standard ice cleats and limits the use of this type of boot solely to skis with telemark bindings. Besides the right and left binding problem, it is always very difficult to fit the boots in the bindings. The skier is frequently obliged to place one knee on the ground to immobilize the ski and be able to lock the tension system on the heel of the boot. These operations are made even more difficult, in the presence of snow. Indeed, as skis are rarely equipped with “ski stops”, they slip easily sometimes making the locking operation tedious. Finally, boot removal in the case of a fall is practically impossible, such that the use of these bindings therefore involves a high risk of injury for skiers.
- In 1995, the company ROTTEFELLA filed a German patent application, which was extended by an international patent application published under the number WO 96/23558. This document outlines and details a new binding concept between a boot and an item of sports equipment, such as a ski in particular. The fundamentals of this concept would lead ten years later to a new standard called NTN, which will be explained hereinafter in the present description. The idea developed in WO 96/23558 is no longer that of binding the boot to the ski between the toe and the heel, but of merely binding the so-called metatarsophalangeal joint zone with the sports equipment. The concept of this invention was that of providing an enhanced binding device, reconciling the problems of lifting the heel of the boot, torsion control and material fatigue. The idea of a specific binding of the so-called metatarsophalangeal joint has indeed offered a number of advantages in the practice of sport and particularly of telemark skiing. However, the main objective, which was to resolve material fatigue, has never been achieved as will be explained in more detail hereinafter in the present description.
- In the mid-2000s, a group of manufacturers defined the new standard mentioned above, called “New Telemark Norm” or NTN, which establishes a new ski/boot interface standard. The new boots, defined by this standard, can be used for telemark or alpine skiing, and can receive standard ice cleats. The sole of the boot is divided into two parts: the front sole specific to the NTN standard and the heel which is conventional and separate from the front sole. The specificity of the front sole stems from the projection (NTN attachment zone) which is located at the level of the arch of the foot at the center of the boot, at the rear end of the front sole. Thus the boot can be rigidly connected to the ski while being held between the front portion of the front sole and the projection. The sole is also symmetrical. This new standard has made it possible to create bindings which combine the freedom of movement of the heel specific to telemark skiing and which incorporate a safety device releasing the boot if the skier falls. As the bindings are symmetrical, the user can put on the ski that they wish as they would for conventional alpine ski bindings, there is no longer any left or right ski. Addressing a number of problems of the 75 norm standard, these bindings can also incorporate ski stops and provide extra safety for skiers.
- Among the binding models complying with the NTN standard, mention will particularly be made of the binding described in
document EP 1 790 396, which is marketed by the company ROTTEFELLA under the trade name FREERIDE™. This binding comprises an assembly for immobilizing the front end of the boot, which particularly includes a toe piece. This toe piece, in the shape of a horseshoe, holds the front of the boot and the lateral overhangs ensuring a satisfactory hold of the boot. The boot is kept flat along thefront 40 millimeters of the boot. Therefore, the first 30 millimeters of the shell of the boot are also kept flat by the toe piece which exerts the holding function thereof on the lateral overhangs of the sole. - In the mode of Telemark use, the front immobilization assembly cited above is locked in rotation with respect to the ski. The front part of the boot is kept flat, parallel with the ski. The toe piece being locked in rotation, the boot is constrained when the heel is lifted. It is firstly observed that, when practicing Telemark skiing, the sole of the boot is considerably damaged. On lifting the heel, when the gusset is fully compressed, the area of the boot located between the front of the gusset and the portion held by the toe piece is deformed as the portion of the sole located immediately above is locked in the toe piece. The lateral overhangs of the boots are marked considerably and sometimes tear. After a few months of use, the boot is irremediably deformed and substantial play between the boot and the binding appears, introducing a floating sensation which limits ski control precision.
- Moreover, the toe piece is also subject to substantial stress, such that there is a substantial risk of mechanical rupture of this part. Finally, this binding does not offer progressive flexion for the user seeking to practice Telemark skiing. In particular, during certain flexural movement phases completed by the user, this flexion is not perceived as regular, varies considerably sometimes with play and moments without tension.
- This binding offers an additional mode of use, of ski touring type, wherein this front immobilizing assembly is freed, so as to be able to pivot with respect to the ski about a transverse axis located under the front portion of the sole of the boot. Therefore, in telemark mode, the toe piece is locked whereas in ski touring mode, the toe piece is free to rotate.
- In sum, the type of bindings, described above, involves numerous drawbacks, particularly deformation and wear of the boots due to the stress created by the new geometry of the toe piece as well as the high levels of stress in the binding.
- Bindings complying with the NTN standard are known, which are marketed by the company 22DESIGN under the reference OUTLAW™. This binding uses a short toe piece with little engagement of the sole. Only the first 10 millimeters of the sole are engaged in the toe piece. The lateral overhangs of the sole not being held. This choice allows a certain degree of rotation of the boot within this toe piece. Accordingly, the locking sensation is reduced, particularly with regard to the solution described immediately above. However, this reduction in length of the toe piece gives rise to significant risks of the boot coming out of this toe piece. This also results in less precision during edging when the user wishes to take a bend. Indeed, as the overhangs of the sole are not used, the lateral load transmission is reduced. The user can thus perceive the play of the boot in the binding due to the weak engagement of the boot. In order to remedy this specific drawback, it has been proposed to incorporate powerful springs, so as to lock the boot at the bottom of the toe piece. This significant return force requires a very high level of physical exertion, however, when practicing Telemark skiing. Moreover, it is also accompanied by premature sole wear, as in the FREERIDE binding described above.
- In view of the above, the aim of the present invention is that of remedying at least some drawbacks of the prior art mentioned above.
- The introduction of the NTN standard has divided the telemark community, as the products proposed required a change of technique. In 2014, the applicant introduced a new product names MEIDJO™ onto the market which, while using boots conforming to the NTN standard, makes it possible to regain the sensations of conventional so-called “75 norm” bindings. The present invention proposes first of all to offer the same convenience of use.
- The aim of the present invention is also that of proposing a binding which makes it possible to reduce mechanical stress, when practicing Telemark skiing.
- The aim of the present invention is also that of proposing such a binding, which prevents any untimely wear of the boot.
- The aim of the present invention is also that of proposing such a binding, which ensures pleasant practice of Telemark skiing for the user, particularly by allowing the most natural leg flexion possible with regular and progressive tension.
- The aim of the present invention is also that of proposing such a binding, which enables boot fitting that is particularly simple and quick to carry out.
- Finally, the aim of the invention is that of proposing such a binding which is capable of incorporating, on the front part thereof, a safety system with a view to boot removal.
- This invention relates to a binding wherein the front assembly (referenced 3 in appended
FIG. 1 ) is mounted in a floating manner and free to rotate on an axis (referenced A3 inFIG. 1 ) perpendicular to the skier's direction of natural movement, ideally positioned just in front of the boot. This floating front assembly associated with a suitable tension system (formed byreferences -
- During the first phase of lifting the heel (angle up to approximately 30°), as shown in appended
FIG. 8 , the front assembly (2) is held in the horizontal position. Indeed, the pressure exerted by the user on the base of the front assembly (32) combined with the pivot axis (A3) located in front of the boot, applies a reverse tilting force to the heel lift direction. Naturally, the mechanism keeps the front part of the boot flat. For this reason, the pressure is maximum on the ski and enables good path control. - During the second phase of lifting the heel (lift angle greater than 30°—see
FIG. 9 appended) when the user extends their step or when they are obliged to bend more to cushion the fault in the terrain, the stress exerted by the boot on the toe piece (32) becomes greater. As the front assembly is free to pivot, the force exerted by the boot on the toe piece naturally actuates the front assembly which can pivot about the axis (A3) and accompany the boot. In this specific case, the triangle of forces is enlarged. The force of the springs being maximal, the user can perfectly control their ski without excessive stress on the boot at the toe piece (32).
- During the first phase of lifting the heel (angle up to approximately 30°), as shown in appended
- According to the invention, at least of the above aims is achieved by a ski binding (1; 101), in particular a ski touring, telemark or cross-country ski binding, for binding a ski boot (8; 208), including a sole (81; 281) and a heel (84; 284), said ski binding (1) including:

- characterized in that the front immobilization assembly (3, 103; 203) is mounted in a floating manner on the front plate, about a transverse pivot axis (A3; A103; A203) located, viewed longitudinally, in front of a so-called supporting point (32′) belonging to the front assembly, said supporting point enabling the front end (81′) of the sole (81; 281) of the boot to be supported,
- the hinged axis (A6) of the rear retaining assembly (6; 106; 206), with respect to the front plate (2, 102; 202), being distinct from the transverse pivot axis (A3), this hinged axis (A6) of the rear retaining assembly (6; 106) being located to the rear, with reference to the direction of movement of the ski, of this transverse pivot axis.

- tensioning means (66; 266; 266′) which act between the rear retaining assembly (6; 106; 206) and the ski and/or the front plate (2, 102; 202), which are capable of tensioning the boot (8; 208) on the binding (1; 101; 201) and enabling the heel (84; 284) to be lifted freely,
- the front immobilization assembly (3, 103; 203) being mounted in a floating manner on the front plate, about a transverse pivot axis (A3; A103; A203),
- the hinged axis (A6) of the rear retaining assembly (6; 106) being distinct from the transverse pivot axis (A3), this hinged axis (A6) of the rear retaining assembly (6; 106) being located to the rear, in the direction of movement, of this transverse pivot axis.
- this method being characterized in that the front immobilization assembly (3, 103; 203) is mounted in a floating manner on the front plate, about a transverse pivot axis (A3; A103; A203),
- the hinged axis (A6) of the rear retaining assembly (6; 106; 206), with respect to the front plate (2, 102; 202), is distinct from the transverse pivot axis (A3), this hinged axis (A6) of the rear retaining assembly (6; 106) being located to the rear, with reference to the direction of movement of the ski, of this transverse pivot axis,
- and in that the positioning of the pivot axis is adjusted and, where applicable, the tensioning means are adjusted such that, in a first flexion phase, the front immobilization assembly (3, 103; 203) does not pivot substantially and, in a second greater boot flexion phase, this front immobilization assembly (3, 103; 203) pivots with respect to the plate.
- According to an advantageous feature of this method, the distance (L36) separating, along a longitudinal direction, the transverse pivot axis (A3) and the hinged axis (A6) of the rear retaining assembly is furthermore adjusted.
- The invention finally relates to a ski comprising a binding (1) as above.
- It is to the applicant's credit of having identified that certain drawbacks of the prior art, as described in particular in
EP 1 790 396, arise from locking the toe piece with respect to the ski, in the Telemark position. Indeed, such locking is the source of significant mechanical stress, which results in premature wear of the boot and the binding. - In substance, this stress is inherent to the immobilization of the front portion of the sole in the toe piece of the binding. Indeed, during flexion associated with telemark skiing, the front portion of the sole is gripped in the toe piece. The latter being fixed, this results in significant deformation of the sole, which bears on this toe piece. Over time, the whole boot is deformed, and the sole develops play in the toe piece, inducing deformation of the shoe and a significant loss of precision for the user.
- On the contrary, according to the invention, the immobilization assembly is mounted in a floating manner. In other words, the pivoting of this assembly with respect to the ski is entirely free, i.e. the invention avoids the use of a locking member as described in
EP 1 790 396. - Accordingly, this floating and rotatable property makes it possible to substantially reduce the stress exerted on the binding according to the invention, as well as on the shoe immobilized in this binding. In this regard, the stress associated with the tilting torque at the front zone of the boot is reduced, given that the boot can tilt when the toe piece is subject to substantial stress. Under these conditions, the service life both of the binding and the boot is enhanced.
- Moreover, according to a particularly advantageous feature of the invention, the floating property described above is not accompanied by instability, which would be detrimental to the satisfactory use of the binding. Indeed, the pivot axis of the immobilization assembly, with respect to the front plate, is positioned judiciously. In this regard, a person skilled in the art would be able to adjust certain dimensional parameters which will be detailed hereinafter.
- Accordingly, during the initial flexion phase, the user's weight induces natural downward tilting of the toe of the boot, in the opposite direction of this flexion. In this way, the immobilization assembly is substantially fixed whereas the front of the shoe is kept flat, in a stable manner. The immobilization assembly is then moved, during a more accentuated phase of this flexion, so as to follow the pivoting of the boot. The overall flexural movement is therefore carried out particularly naturally, which is very pleasant for the user.
- It is also to the applicant's credit of having identified the drawbacks of the prior art, as described in WO 96/23558. In substance, this document applies an interpretation of the drawings to outline an operational product suitable for industrialization. The analysis of
FIG. 1 , which is the basis of the teaching of WO 96/23558, describes a binding concept wherein the boot is held by the toe and a protuberance located under the sole, as well as a tension system connecting these two zones. It should be noted that the tension system is connected to the toe piece which holds the toe of the boot by means of an axis numbered 23 in this figure. A person skilled in the art would readily understand that this concept may indeed work in theory, but only on one condition: the toe piece must be locked or significantly restricted in rotation. This condition is required for the tension system to work, otherwise the boot pivots with the toe piece without stretching the tension system. This condition is indeed fulfilled thanks to the part 25 seen inFIG. 1 which restricts the rotation of the assembly 22. This condition is also detailed inFIGS. 6, 7 and 14 of the document WO 96/23558, where it can be seen that the part 22′ (FIGS. 6 and 7 ) or the part 54 (FIG. 14 ) is not movable but rigidly connected to the ski. It will therefore be noted that the binding concept, detailed in document WO 96/23558, the toe piece is either locked or significantly restricted in the rotation thereof. -

assembly 3 firstly comprises amember 30, for supporting the front of aboot 8 as illustrated particularly inFIG. 4 , as well as 15 to 18. This boot, complying with the NTN standard as described above, is more specifically illustrated inFIG. 20 . In a manner known per se, thisboot 8 comprises a sole 81, from which theshoe 82 extends. Moreover, a lug (front contact zone) 83, for locking the boot, projects to the front from the sole 81. According to the invention, this lug 83 is not part of this sole. - The supporting
member 30 cited above comprises abottom plate 32, from which two lateral flanks 34 extend, as well as afront seat 36. Each flank 34 is perforated with an orifice 35, allowing the passage of the physical axis extending along the axis A3. The front end of theplate 32, as well as theseat 36, are curved according to the shape of the front end of the vamp of theboot 8. Moreover, the supportingmember 30 is equipped with acap 38, enabling the hinging of alatch 50 as will be seen hereinafter. - The
assembly 3 further comprises atoe piece 40, which is hinged with respect to the supportingmember 30 about the abovementioned axis A3. Thistoe piece 40 comprising a top covering 42, wherein therear edge 43 is curved. The covering 42 is extended downward bylateral edges 44, which cover the outer face of the flanks 34. Each edge is perforated with arespective orifice 46, which is placed facing the orifice 35 formed in each flank 34. Theplate 32, the flanks 34, theseat 36 and the top 42 delimit a housing 48, for immobilizing theboot 8. - In an embodiment, axes 39 secure the
toe piece 40 and the supportingmember 30. They are immobile with respect to one another, when the boot rotates thetoe piece 40, the supportingmember 30 is also rotated. - During use, the sole 81 of the boot is inserted under this covering 42, whereas the front end of the lug 83 abuts against the
seat 36 as shown inFIG. 4 . In thisFIG. 4 , the point of theplate 32, according to a longitudinal sectional view, supporting thefront end 81′ of the sold 81 is annotated 32′. As mentioned above, thisend 81′ is located immediately to the rear of the lug 83, since the latter is not part of the sole. Moreover, the front end of thevamp 82 of theboot 8 abuts against the abovementionedrear edge 43. The front point of thisedge 43 is annotated 43′, particularly inFIGS. 2 and 4 . Thepoint 32′ of the plate is substantially plumb with thisfront point 43′. - In an embodiment, the
assembly 3 finally comprises alatch 50, ensuring the mutual immobilization of the supportingmember 30 and thetoe piece 40. Thislatch 50 is hinged on theabovementioned cap 38, about an axis A50, parallel with the axis A3 and located to the front thereof. This latch is equipped with anactuation relief 52, hollowed out with arecess 54 for supporting a ski stick. The profile of this latch firstly defines aflat immobilization section 56, designed to be wedged under the covering 42 so as to prevent the pivoting of thetoe piece 40. Thisflat section 56 is extended by a ramp 57, intended to be inserted under the abovementioned covering 42, when pressure is applied on therelief 52. Finally, this ramp ends with a shoulder 58, helping hold thetoe piece 40 by wedging, when the latter has been moved by pivoting away from the supportingmember 30. - The
latch 50 can move between two functional positions, illustrated respectively inFIGS. 16 to 19 . InFIGS. 16 and 17 , the latch is in the active locking position thereof, such that the toe piece 4 and the supportingmember 3 are mutually rigidly connected in rotation. On the other hand, inFIGS. 18 and 19 , the latch is in the idle unlocking position thereof. In this position, the toe piece can pivot freely with respect to the supporting member, about the abovementioned axis A3. - The
rear retaining assembly 6 is of a type known per se, such that it will not be described in detail hereinafter. Thisassembly 6 comprises a base 60, for supporting the front portion of the boot. This base supports tworods 62, each of which enters arespective opening 24, so as to be hinged on theplate 2. Opposite the rods, the base is extended by anose 64 for conventionally attaching the boot, at the level of a lug not shown. As particularly shown inFIG. 10 , the hinged axis A6 of therear retaining assembly 6 with respect to the plate, is located to the rear of the abovementioned axis A3. The technical effect, associated with the mutual positioning between the two axes, will be specified hereinafter. - Furthermore, conventional means 66 for tensioning the
assembly 66, particularly with a spring, are provided. These means 66, which work in compression, tend to move the end of the rods and the coupling nose closer together. Advantageously, these tensioning means are of adjustable intensity, particularly by means ofscrews 68. Finally, thiselement 6 is equipped with means, not shown, for “Step In” type boot fitting. For this purpose, this retainingassembly 6 is advantageously equipped with a tensioning rod cooperating with a stop provided on the ski, according to the teaching of theFrench patent 3 016 799 held by the applicant. - The
heelpiece 7, also of a type known per se, will likewise not be described in detail hereinafter. This heelpiece firstly comprises a supportingelement 70, defining atop surface 71 for positioning the heel of the boot at a determined height. Moreover, this heelpiece can also include a locking member not shown, equipped with locking elements capable of cooperating selectively with the rear portion of the boot. - The use of the binding 1, as described above, will not be explained hereinafter.
- In a first embodiment, the supporting
member 3 and thetoe piece 40 are rigidly connected by theaxes 39. In a further embodiment, it is firstly assumed that thelatch 50 is in the active position thereof, such that thesupport member 3 and thetoe piece 40 are immobilized in rotation, as explained above. The user then exerts an action on the tensioning rod, mentioned above, so as move thenose 64 away from therods 62. Thisnose 64 is then coupled to a retaininglug 85, particularly seen inFIG. 4 , belonging to this boot. In the example illustrated, thislug 85 is provided at the rear end of the front zone of the boot. However, by way of alternative embodiment not shown, thislug 85 can be placed at therear end 84 of this boot. - The user can then practice Telemark skiing, particularly by means of flexion of the inner leg against the tensioning means 66. During this flexion, the user tends to compress or “break” a
gusset 86, provided in the front portion of the boot and clearly visible inFIG. 20 . With reference toFIGS. 7 and 8 , a so-called angle of flexion aF is defined, which is formed between the horizontal and the principal plane P60 of the base 60 of the retainingelement 6. - In a first flexion phase, corresponding to a low value of the angle of flexion (for example 30° in
FIG. 7 ), theimmobilization assembly 3 does not pivot substantially with respect to theplate 2, even if this assembly is mounted in a floating manner as explained above. This means that, with respect to the initial position thereof, theimmobilization assembly 3 forms an angle, annotated a3 inFIG. 8 , which is less than 3° (in the drawing this angle is close to −7°). Accordingly, the front of the boot is kept flat. On the other hand, the rear of the boot is raised, by means of compression of thegusset 86. - Then, when the user continues to bend the boot, the
immobilization assembly 3 then pivots with respect to theplate 2 according to the arrow F3, as shown inFIG. 8 . This pivoting is obtained beyond a threshold value of the angle of flexion, which is for example close to 40°. InFIG. 8 , this angle of flexion has a value of close to 80°. Moreover, theimmobilization assembly 3 forms a significant angle α3, with respect to the initial position thereof, typically greater than 10°. - A person skilled in the art is capable of taking several parameters into account, with a view to optimal operation of the binding 1. In particular, they can adjust the positioning of the axis A3, both in height and along the longitudinal direction of the ski. In this regard,
FIG. 4 illustrates the zone wherein this axis can be positioned. In thisFIG. 4 , theboot 8 is featured, wherein the vamp bears against theedge 43′. Moreover, the lug 83 abuts against theseat 36, whereas thefront end 81′ of the sole bears against the so-calledcharacteristic point 32′ belonging to theplate 32. - The zone Z3, represented overall by a rectangle in this
FIG. 4 , illustrates the different possibilities with a view to the positioning of the axis A3. Preferably, this axis is placed immediately in front of theseat 36, namely immediately facing the lug 83. This means that the distance between thisseat 36 and this axis A3 is very small, typically less than 3 millimeters. - Starting from the
characteristic point 32′, the respectively horizontal and vertical dimensions of the zone Z3 are annotated X3 and Y3. Typically, X3 is less than 40 mm millimeters, preferably than 25 millimeters. By way of example, inFIG. 4 , A3 is located in front of thepoint 32′ along a distance less than 16 mm. - Moreover, typically, Y3 is between −30 millimeters and +30 millimeters with respect to the
point 32′, in which case the axis A3 is positioned vertically more or less above or below the sole of the boot. InFIG. 4 , the axis A3 is positioned facing the sole with a value of Y3 equal to +8 millimeters, namely that this axis is positioned slightly above thispoint 32′. In the case where the axis A3 is placed below the characteristic point, therefore vertically below the sole plane, this makes it possible to free a space, wherein an additional mechanical system, particularly a safety boot removal system of any suitable type, can be provided. - It is noted that, according to an advantageous embodiment of the invention, the axis A3 is located in front of the seat of the toe piece, helping support the lug 83. Nevertheless, it can be envisaged that this axis extends further forward, namely in the vicinity of the supporting
point 32′. In this latter case, this axis extends through the lug 83, i.e. it consists of a geometric axis, but not a physical axis. Suitable means are then provided, enabling the pivoting about this purely geometric, or virtual, axis. These means can be for example return means, such as connecting rods or external pivots placed in theflanks 24, whereon theassembly 3 pivots. - In order to carry out flexion in two phases, which is the most pleasant possible for the user, a person skilled in the art would be able to adjust the value of at least one of these characteristic dimensions X3 and Y3. They would also be able to adjust the force of the tensioning means 66, thanks to the
screw 68. A person skilled in the art can also take into account the user's shoe size or the flexibility of the boot. - Moreover, in this
FIG. 10 , the distance L36 separating along the longitudinal axis the pivot point A3 and the hinge point A6 of therear retaining assembly 6 is noted. As seen above, the axis A3 is located in front of the axis A6 so as to form a triangle of forces formed by these two axes and by the user's heel, which induces a tilting of the shoe. This distance is advantageously between 20 and 120 millimeters, being preferably between 35 and 80 millimeters. In this way, the triangle of forces mentioned above provides particularly satisfactory tilting of this boot. - In the mode of use described in
FIG. 16 to 19 , if the user seeks to remove a boot, they firstly exert a downward pressure on therecess 54, along the arrow f50 inFIG. 18 . Typically, this action is carried out by means of the tip of their stick. This causes a pivoting of the latch about the axis A50 thereof, which is represented by the arrow F50 inFIG. 18 . Accordingly, the flat section is no longer engaged with the covering 42 and the ramp 57 slides along the bottom face of this covering. - The user can then exert an upward action, so as to pivot the toe piece along the arrow F40 in
FIG. 19 . Typically, this action is carried out by means of the washer of the stick. At the end of the travel of the pivoting of the toe piece, the front end of the covering 42 is held in position by the shoulder 58 of the latch, as shown inFIG. 19 . The user can then raise the front end of the boot, for boot removal. It will be noted that this boot removal can be carried out without particular effort, since it is not carried out against the tensioning means 66. -
FIGS. 9 to 12 illustrate a second embodiment of the binding, according to the present invention. This second embodiment is characterized in that the tension system is placed inside theplate 2, helping free the space under the arch of the foot of the boot. This embodiment also makes it possible to design an adjustable axis A6, along the longitudinal direction of the ski. This adjustment of the position of the axis A6 makes it possible to adapt the activity of the binding, according to the boot size or the user's taste. In these figures, all the elements bear the same numbers. Only the elements of the tension system offset to the front appear with the indication “′”. -
FIGS. 13 to 15 illustrate a further embodiment of the binding, according to the present invention. In theseFIGS. 13 to 15 , the mechanical elements equivalent to those inFIGS. 1 to 8 are assigned the same reference numbers therein, increased by the number 100. - The binding 101 according to this embodiment differs from that 1, according to the first embodiment, particularly in that the
immobilization assembly 103 is made of one piece. In other words, thisassembly 103 does not comprise two mutually movable elements, such as the supporting member and the toe piece in the figures above. Moreover, theassembly 103 is devoid of a latch, such as that 50 of the first embodiment, - More precisely, the
assembly 103 comprises twosupport plates 132, which are extended upward by twolateral flanks 134. The upper ends of these flanks are connected by a covering 142, wherein the rear edge 143 is curved according to the shape of the front end of the boot. These mechanical elements delimit ahousing 148, for immobilizing this boot. - It will be noted that, unlike the first embodiment, the
housing 148 is open to the front, namely it is devoid of a seat, such as that 36. Theplates 132 are extended downward by respective edges 133, wherein orifices enabling the passage of a physical axis are formed. The latter provides the hinge of theassembly 103 with respect to thefront plate 102, about a transverse axis A103. - The use of the binding 101 is similar to that of the binding of the first embodiment, in terms of boot fixing, as well as the two flexion phases. On the other hand, boot removal from the binding 101 is different, given that the latter does not include a toe piece pivoting with respect to the supporting member. For this purpose, the user must unhook the
nose 164 with respect to the boot, so as to enable such boot removal. -
FIGS. 21 to 23 illustrate a further embodiment of the binding, according to the present invention. In theseFIGS. 21 to 23 , the mechanical elements equivalent to those of the first embodiment are assigned the same reference numbers therein, increased by the number 200. Moreover, the mechanical elements, equivalent to those in the embodiment inFIGS. 13 to 15 , are assigned the same reference numbers thereof increased by the number 100. - The binding 201 according to this embodiment is firstly similar to that 101, in that the supporting member and the toe piece are not mutually movable. In other words, the immobilization assembly of 103 is made of a single piece. It will be noted that, in
FIG. 21 , the physical axis A203 is represented. - On the other hand, unlike the preceding embodiments, the retaining
assembly 206 is not hinged on theplate 202. On the contrary, thisassembly 206 is mounted directly on theimmobilization assembly 203, with the possibility of sliding. For this purpose, aflexible guide 268, connecting these two assemblies, is provided. - Moreover, the
plate 202 includes ahousing 228, wherein aspring 266 is mounted. The rear end of this spring is placed facing astop 229, whereas the front end of this spring is rigidly connected to acable 266′, which is mounted on thenose 264. When the user bends forward, the cable compresses the spring, namely the front end thereof is moved to the rear. - Moreover, this cable is wound, forming a bend, about the axis A206. It will be noted that the latter is capable of sliding with respect to the plate, such that the length L236 is variable. In the front view, three different values of this length have been shown. This embodiment is advantageous, inter alia due to the fact that the spring is offset to the front. Accordingly, this makes it possible to free space to the rear of the binding, under the user's actual foot.
