Definitions
- Ski binding in particular telemark skiing, and ski equipped with such a binding
- the present invention relates to a ski binding, more particularly of the telemark type. However, it finds its application to bindings fitted to other types of ski, such as cross-country skis, which the user wishes to use in "telemark" mode.
- ski touring, telemark ski or cross-country ski bindings allow easy lifting of the heel in practice either for climbing or for taking the telemark step to make a turn. To be able to perform this gesture, the bindings ensure that the front toe of the shoe is held in place by a stirrup that leaves the heel free to move.
- bindings according to “standard 75”, such as for example the bindings described in US patent 7,401, 802 (Black Diamond Equipment).
- This type of binding is characterized by a fixed front socket, which maintains the so-called “duckbill" shape located at the front of the shoe, as well as a cable tension system equipped with springs locking on the heel of the shoe.
- the standard of these bindings requires having a right and a left binding.
- the shape of the soles is asymmetrical, with a more flared shape towards the outside of the foot. By cons, it is possible to put a right shoe in a left binding, it follows that the ski will not be aligned with the shoe resulting in great difficulty in skiing.
- NTN New Telemark Norm
- the new boots defined by this standard, can be used in telemark or alpine skiing, and can receive standard glacier crampons.
- the sole of the shoe is divided into two parts: the front sole specific to the NTN standard and the heel which is classic and distinct from the front sole.
- the specificity of the front sole comes from the protrusion (grip area NTN) which is located at the arch of the shoe in the center of the shoe, at the rear end of the front sole.
- the boot can be secured to the ski by being held between the front part 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 and which integrate a safety device releasing the boot in the event of a fall of the skier.
- the bindings being symmetrical the user can put on the ski he wishes as he would for conventional alpine ski bindings, there is no longer left or right ski.
- these bindings can also integrate ski stops and bring an additional safety for skiers.
- This binding comprises a set for immobilizing the front end of the shoe, which includes in particular a stirrup.
- This horseshoe-shaped stirrup holds the front of the shoe and the lateral overhangs ensuring good support of the shoe.
- the shoe is held flat over the front 40 millimeters of the shoe. So the first 30 millimeters of the shoe shell are also held flat by the stirrup which exerts its holding function on the lateral overhangs of the sole.
- the above-mentioned front immobilizer assembly is locked in rotation relative to the ski.
- the front part of the boot is kept flat, parallel to the ski.
- the stirrup being locked in rotation the shoe is constrained when the heel is raised.
- the sole of the shoe is badly damaged.
- the heel is raised, when the bellows is completely flattened, the area of the shoe located between the front of the bellows and the part held by the stirrup deforms because the part of the sole located just before is blocked in the stirrup.
- the side edges of the shoes are strongly marked and sometimes tear. After a few months of use, the boot is irreparably deformed and a significant play between the boot and the binding appears, introducing a feeling of floating which limits the precision of piloting the ski.
- this binding does not offer progressive bending for the user wishing to practice Telemark. In particular, during certain phases of the flexion movement performed by the user, this flexion is not felt as regular, varies a lot with sometimes games and moments without tension.
- This binding offers an additional mode of use, of the hiking type, in which this front immobilization assembly is released, so as to be able to pivot relative to the ski around a transverse axis located under the front part of the sole of the shoe. So in telemark mode the stirrup is blocked while in hiking mode the stirrup is free to rotate.
- the type of fasteners described above involves many drawbacks, notably deformation and deterioration of the shoes due to the stresses created by the new geometry of the stirrup as well as high stresses in the fastening.
- the present invention aims to remedy at least certain drawbacks of the prior art mentioned above.
- the present invention also aims to propose a fixing which makes it possible to reduce the mechanical stresses, during the practice of Telemark.
- the present invention also aims to provide such a binding, which avoids any untimely deterioration of the shoe.
- the present invention also aims to provide such a fixation, which ensures a pleasant practice of Telemark for the user, in particular by allowing the most natural possible leg flexion with regular and progressive tension.
- the present invention also aims to provide such a binding, which allows a particularly simple and quick fitting to put on.
- the present invention finally aims to provide such a fixing which is capable of integrating, on its front part, a security system for the purpose of heaving.
- the object of this invention is a binding whose front assembly (referenced 3 in attached FIG. 1) is mounted floating and free to rotate on an axis (referenced A3 in this FIG. 1) perpendicular to the natural direction of movement of the skier, ideally placed just in front of the shoe.
- This floating front assembly associated with an adequate tension system (formed by the references 6 and 66 in the appended figures), making it possible to create a suitable triangle of forces, offers the user a flexion with a regular and progressive restraint tension and this without undue stress on the material.
- This invention therefore limits the internal forces in the system without constraining the shoe excessively.
- the effect of the floating front assembly with a pivot point ideally placed just in front of the shoe allows two phases of optimal use for the user:
- a ski binding (1; 101) in particular a ski touring, telemark or cross-country ski binding, for fixing a boot ( 8; 208) ski, comprising a sole (81; 281) and a heel (84; 284), said ski binding (1) comprising: a front plate (2; 102; 202), with reference to the direction of movement of the ski, this front plate being intended to be secured to the ski,
- a front assembly (3; 103; 203) for immobilizing the shoe, capable of cooperating with the sole (81; 281) of the shoe (8; 208),
- this rear assembly (6; 106; 206) for retaining the boot, with reference to the direction of movement of the ski, this rear assembly being able to cooperate with a retaining lug (85; 285) of the rear part of the sole front and / or with the rear sole, this rear assembly being movable relative to said front plate in the vertical plane,
- the front immobilization assembly (3, 103; 203) is mounted floating on the front plate, around a transverse pivot axis (A3; A103; A203) situated, in longitudinal view, in front of a point (32 ′) of said support belonging to the front assembly, this support point allowing the support of the front end (81 ′) of the sole (81; 281) of the shoe,
- this articulation axis (A6) of the rear retaining assembly (6; 106) being located behind, with reference to the direction of movement of the ski, of this transverse pivot axis.
- the fixing of the invention may include all or part of the following characteristics, insofar as they are technically compatible:
- the transverse pivot axis (A3) is located, in the longitudinal direction, in front of a point (36) called a stop belonging to the front assembly, this stop point (36) allowing the stop of the front end d '' a locking lug (83) belonging to the shoe,
- transverse pivot axis (A3) is located, in longitudinal view, immediately in front of said abutment point (36),
- the distance (L36) separating, in a longitudinal direction, the transverse pivot axis (A3) and the articulation axis (A6) of the rear retaining assembly (6) is between 20 and 120 mm, especially between 35 mm and 80 mm,
- the immobilization assembly in a first bending phase, does not pivot substantially and, in a second greater bending phase of the shoe, this immobilization assembly pivots relative to the plate, the distance (X3) separating, in a longitudinal direction, the transverse pivot axis (A3) and the fulcrum (32 ') is between 0 and 40 mm, in particular between 0 and 25 mm,
- the distance (Y3) separating, in a vertical direction, the transverse pivot axis (A3) and the support point (32 ’) is between -30 mm and +30 mm
- the front immobilization assembly (3) of the shoe comprises a stirrup (40) and a support member (30) of the shoe, mutually movable between an immobilization position and a shoe release position, this front assembly further comprising a locking element (5) making it possible to mutually lock the stirrup and the support member, in said immobilized position,
- 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 the binding of a ski boot (8; 208), comprising a sole (81; 281) and a heel (84; 284), said ski binding (1) comprising:
- a front assembly (3; 103; 203) for immobilizing the shoe, capable of cooperating with the sole (81; 281) of the shoe (8; 208),
- a rear assembly (6; 106; 206) for retaining the boot, capable of cooperating with a retaining lug (85; 285) of the rear part of the front sole and / or with the rear sole, this rear assembly being movable relative to said front plate in the vertical plane,
- the front immobilization assembly (3, 103; 203) being mounted floating on the front plate, around a transverse pivot axis (A3; A103; A203),
- this articulation axis (A6) of the rear retaining assembly (6; 106) being distinct from the transverse pivot axis (A3), this articulation axis (A6) of the rear retaining assembly (6; 106) being located behind, in the direction of movement, of this transverse pivot axis,
- this process being characterized in that the front immobilization assembly (3, 103; 203) is mounted floating on the front plate, around a transverse pivot axis (A3; A103; A203),
- the hinge axis (A6) of the rear retaining assembly (6; 106; 206), relative to the front plate (2, 102; 202), is distinct from the transverse pivot axis (A3) , this axis articulation (A6) of the rear retaining assembly (6; 106) being located behind, with reference to the direction of movement of the ski, of this transverse pivot axis, and in that the positioning of the pivot axis and, if necessary, the tensioning means are adjusted so that, in a first bending phase, the assembly before immobilization (3, 103; 203) does not pivot substantially and, in a second phase of greater flexion of the shoe, this assembly before immobilization (3, 103; 203) pivots relative to the plate.
- the distance (L36) separating, in a longitudinal direction, the transverse pivot axis (A3) and the articulation axis (A6) of the rear retaining assembly is further adjusted. .
- the invention finally relates to a ski comprising a binding (1) as above.
- the immobilizer assembly is mounted floating.
- the pivoting of this assembly relative to the ski is entirely free, that is to say that the invention overcomes the use of a locking member such as that described in EP 1 790,396.
- the floating character described above is not accompanied by instability, which would be detrimental to the satisfactory use of the binding.
- the pivot axis of the immobilizer assembly, relative to the front plate is positioned judiciously.
- the person skilled in the art can adjust certain dimensional parameters which will be detailed below.
- the weight of the user causes a natural tilting of the front toe of the shoe downward, in the opposite direction of this flexion.
- the immobilization assembly is substantially fixed while the front of the shoe is held flat, in a stable manner.
- the immobilizer assembly is then driven in movement, during a more accentuated phase of this flexion, so as to accompany the pivoting of the shoe.
- the overall flexion movement therefore takes place in a particularly natural way, which is very pleasant for the user.
- FIG. 1 which is at the basis of the teaching of WO 96/23558, presents a concept of fixation whose shoe is held by the front point and a protuberance located under the sole, as well as a system of tension connecting these two zones. It will be noted that the tension system is linked to the stirrup which maintains the front point of the shoe by means of an axis numbered 23 in this figure. Those skilled in the art will readily understand that this concept can certainly work in theory, but only on one condition: the stirrup must be blocked or strongly limited in rotation.

- Figures 21 to 23 are respectively perspective, side and longitudinal section views, illustrating a fastening according to an additional embodiment of the invention.
- the binding 1 essentially comprises a front plate 2, a front immobilizing assembly 3, a rear retaining assembly 6 and a heel piece 7.
- the front plate 2 firstly comprises a base 20, intended to be placed flat on a ski 9, as is shown in particular in Figure 1.
- the base is hollowed out with holes 21, allowing the passage of fixing means, not shown.
- these fixing means are for example removable, in particular of the screw type.
- Two wings 22, mutually parallel, extend upwards from the base 20. These wings 22 define recesses 23 intended to support the immobilization assembly 3, in the low position of the latter.
- each wing 22 is pierced with an opening 24, intended for the articulation of the retaining assembly 6 as will be seen in the following.
- the front immobilization assembly 3 is articulated relative to the plate 2, around a transverse axis denoted A3. It will be noted that, in accordance with the invention, this assembly 3 is mounted "floating" relative to this plate 2 or, in other words, is free to rotate relative to this plate. Still otherwise expressed, there is no provision for a specific member intended for the mutual blocking of the plate 2 and of the assembly 3, in rotation about this axis A3.
- This assembly 3 firstly comprises a member 30, allowing the support of the front of a shoe 8 as illustrated in particular in Figure 4, as well as 15 to 18.
- This shoe, meeting the NTN standard such as presented above, is more particularly illustrated in FIG. 20.
- this shoe 8 comprises a sole 81, from which extends the shoe 82. Furthermore a lug (front contact area) 83 , allowing the blocking of the shoe, protrudes forward from the sole 81. Within the meaning of the invention, this lug 83 is not part of this sole.
- the abovementioned support member 30 comprises a lower plate 32, from which extend two lateral flanks 34, as well as a front bottom 36. Each flank 34 is pierced with an orifice 35, allowing the passage of the physical axis extending along the A3 axis.
- the front end of the plate 32, as well as the bottom 36, are curved according to the shape of the front end of the upper of the shoe 8.
- the support member 30 is provided with a yoke 38, allowing the articulation of a lock 50 as will be seen in the following.
- the assembly 3 further comprises a stirrup 40, which is articulated relative to the support member 30 around the aforementioned axis A3.
- This stirrup 40 comprises an upper web 42, the rear edge 43 of which is curved.
- the veil 42 is extended downwards by lateral flanges 44, which cover the outer face of the flanks 34.
- Each flange is pierced with a respective orifice 46, which is placed opposite the orifice 35 formed in each flank 34.
- the plate 32, the sides 34, the bottom 36 and the veil 42 define a housing 48, allowing the shoe 8 to be immobilized.
- pins 39 secure the stirrup 40 and the support member 30. They are stationary with respect to each other, when the shoe causes the stirrup 40 to rotate, the support member 30 is also rotated.
- the sole 81 of the shoe is inserted under this veil 42, while the front end of the lug 83 abuts against the bottom 36 as shown in Figure 4.
- 32 ′ the point of the plate 32, in a view in longitudinal section, on which the front end 81 ′ of the sole 81 is supported. As mentioned above, this end 81 ′ is located immediately behind the lug 83, since the latter is not part of the sole. Furthermore, the front end of the upper 82 of the shoe 8 abuts against the aforementioned rear edge 43.
- 43 ′ the front point of this edge 43, in particular in FIGS. 2 and 4.
- the point 32 ′ of the plate is substantially perpendicular to this front point 43 ′.
- the assembly 3 finally comprises a lock 50, ensuring the mutual immobilization of the support member 30 and the stirrup 40.
- This lock 50 is articulated on the above-mentioned yoke 38, around a axis A50, parallel to axis A3 and located in front of the latter.
- This lock is provided with an actuation relief 52, hollowed out by a recess 54 allowing the support of a ski pole.
- the profile of this lock first of all defines a flattening section 56 for immobilization, intended to be trapped under the web 42 in order to prevent the pivoting of the stirrup 40.
- This flat section 56 is extended by a ramp 57, intended to slide under the aforementioned veil 42, when the relief 52 is pressed.
- this ramp is terminated by a shoulder 58, allowing the stirrup 40 to be held in place when the latter has been moved by pivoting opposite to the support member 30.
- the lock 50 is movable between two functional positions, illustrated respectively in Figures 16 to 19.
- the lock In Figures 16 and 17, the lock is in its active locking position, so that the bracket 4 and the support member 3 are mutually integral in rotation.
- the lock In FIGS. 18 and 19, the lock is in its inactive unlocking position. In this position, the stirrup can pivot freely relative to the support member, around the aforementioned axis A3.
- the rear restraint assembly 6 is of a type known per se, so it will not be described in detail below.
- This set 6 includes a base 60, allowing the support of the front part of the shoe.
- This base supports two rods 62, each of which penetrates into a respective opening 24, so as to be articulated on the plate 2.
- the base is extended by a spout 64 allowing conventionally the attachment of the shoe, at a lug not shown.
- the axis denoted A6 of articulation of the rear retaining assembly 6 relative to the plate is located behind the abovementioned axis A3. The technical effect, linked to this mutual positioning between the two axes, will be explained in the following.
- the heel piece 7 also of a type known per se, will not be described in detail below either.
- This heel piece firstly comprises a support element 70, defining an upper surface 71 allowing the heel of the shoe to be positioned at a determined height.
- this heel piece may also include a locking member, not shown, equipped with locking elements capable of cooperating selectively with the rear part of the shoe.
- the support member 3 and the stirrup 40 are secured by the pins 39.
- the latch 50 is in its active position, so that the support member 3 and the stirrup 40 are immobilized in rotation, as explained above
- the user then moves his shoe forward, so that the front end of the latter is immobilized in the housing 48 described above.
- the user then exerts an action on the tensioning link, mentioned above, so as to move the spout 64 away from the rods 62.
- This spout 64 is then hooked onto a retaining lug 85, visible in particular in Figure 4, belonging to this shoe.
- this lug 85 is provided at the rear end of the front area of the shoe.
- this lug 85 can be placed at the rear end 84 of this shoe.
- a so-called flexion angle aF is defined which is formed between the horizontal and the main plane P60 of the base 60 of the element retainer 6.
- the immobilizing assembly 3 does not pivot substantially relative to the plate 2, even if this assembly is mounted floating as explained above. This means that, relative to its initial position, the immobilizing assembly 3 forms an angle, noted a3 in FIG. 8, which is less than 3 ° (in the drawing this angle is close to -7 °). Therefore, the front of the shoe is kept well flat. On the other hand, the rear of the shoe is raised, by means of compression of the bellows 86.
- the immobilization assembly 3 pivots relative to the plate 2 according to arrow F3, as shown in FIG. 8. This pivoting is obtained beyond a threshold value of the bending angle, which is for example close to 40 °. In FIG. 8, this bending angle has a value close to 80 °. Furthermore, the immobilizer assembly 3 forms a significant angle a3, with respect to its initial position, typically greater than 10 °.
- Figure 4 illustrates the area in which this axis can be positioned.
- the lug 83 abuts against the bottom 36, while the front end 81 ′ of the sole comes to bear against the so-called characteristic point 32 ′ belonging to the plate 32.
- this axis is placed immediately in front of the bottom 36, namely immediately opposite the lug 83. This means that the distance between this bottom 36 and this axis A3 is very small, typically less than 3 millimeters.
- X3 and Y3 denote the horizontal and vertical dimensions of the zone Z3 respectively.
- X3 is less than 40 mm millimeters, preferably 25 millimeters.
- A3 is located in front of point 32 ’at a distance of less than 16 mm.
- Y3 is between -30 millimeters and + 30 millimeters relative to the point 32 ', in which case the axis A3 is positioned vertically more or less above or below the sole of the shoe .
- the axis A3 is positioned opposite the sole with a value of Y3 equal to +8 millimeters, namely that this axis is positioned slightly above this point 32 '.
- the axis A3 is placed below the characteristic point, therefore vertically below the plane of the sole, this makes it possible to free up a space, within which a system can be provided.
- additional mechanical in particular a safety release system of any suitable type.
- the axis A3 is located in front of the bottom of the stirrup, allowing the support of the lug 83.
- this axis extends through lug 83, that is to say that it is a geometric axis, but not a physical axis.
- Appropriate means are then provided, allowing pivoting around this purely geometric, or virtual, axis. These means may for example be return means, such as connecting rods or external pivots placed in the sides 24, on which the assembly 3 pivots.
- the skilled person can adjust the value of at least one of these characteristic dimensions X3 and Y3. It can also adjust the strength of the tensioning means 66, using the screw 68. A person skilled in the art can also take into account the size of the user or the flexibility of the shoe.
- the axis A3 is located in front of axis A6 so as to form a triangle of forces formed by these two axes and by the heel of the user, 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 ensures a very satisfactory tilting of this shoe.
- FIGS 9 to 12 illustrate a second embodiment of the attachment, according to the present invention.
- This second embodiment is distinguished by the fact that the tension system is placed inside the plate 2, making it possible to free the space under the arch of the shoe.
- 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 A6 axis makes it possible to adapt the activity of the binding, depending on the size of the shoe or on the user's taste. In these figures all the elements have the same numbers. Only the elements of the tension system deported to the front appear with the mention "‘ ".
- FIGS. 13 to 15 illustrate another embodiment of the binding, according to the present invention.
- the mechanical elements similar to those of FIGS. 1 to 8 are assigned thereto the same reference numbers, increased by the number 100.
- the binding 101 according to this embodiment differs from that 1, according to the first mode, in particular in that the immobilization assembly 103 is produced in one piece.
- this assembly 103 does not include two mutually movable elements, such as the support member and the bracket of the figures above. Furthermore, the assembly 103 does not have a lock, such as that 50 of the first embodiment.
- the assembly 103 comprises two support plates 132, which are extended upwards by two lateral flanks 134.
- the upper ends of these flanks are connected by a web 142, the rear edge 143 of which is curved along the shape of the front end of the shoe.
- These mechanical elements define a housing 148, allowing the immobilization of this shoe.
- the housing 148 is open towards the front, namely that it has no bottom, such as that 36.
- the plates 132 are extended downwards by respective flanges 133, in which are formed orifices allowing the passage of a physical axis. The latter ensures the articulation of the assembly 103 relative to the front plate 102, around a transverse axis A103.
- the use of the binding 101 is analogous to that of the binding of the first embodiment, as regards the footwear, as well as the two flexion phases. However, the release of the binding 101 is different, since the latter does not include a pivoting stirrup relative to the support member. To this end, the user must unhook the spout 164 relative to the shoe, so as to allow such heaving.
- FIGS. 21 to 23 illustrate another embodiment of the binding, according to the present invention.
- the mechanical elements analogous to those of the first embodiment are assigned to them the same reference numbers, increased by the number 200.
- the mechanical elements, analogous to those of the embodiment of FIGS. 13 to 15, are assigned the same reference numbers increased by the number 100.
- the binding 201 according to this embodiment is first of all similar to that 101, in that the support member and the stirrup are not mutually mobile. In other words, the 103 asset package is all in one piece. It will be noted that, in FIG. 21, the physical axis A203 has been represented.
- the retaining assembly 206 is not articulated on the plate 202.
- this assembly 206 is mounted directly on the immobilization assembly 203, with the possibility of sliding.
- a flexible guide 268 is provided, connecting these two assemblies.
- the plate 202 comprises a housing 228, in which a spring 266 is mounted.
- the rear end of this spring is placed opposite a stop 229, while the front end of this spring is integral with a cable 266 ', which is mounted on the spout 264.
- the cable compresses the spring, namely that the front end of the latter is moved rearward.
- this cable is wound, forming a bend, around the axis A206. Note that the latter is capable of sliding relative to the plate, so that the length L236 is variable. In the front view, three different values of this length have been plotted.
- This embodiment is advantageous, inter alia, because the spring is offset forward. As a result, this frees up space at the back of the binding, under the wearer's actual foot.
