Ski binding and sole for a ski boot
The invention relates to a ski binding and a sole for a ski boot.
More specifically, the invention relates to a ski binding and sole for a ski boot for cross-country skiing, classic style, skating / freestyle, touring and telemark skiing.
BACKGROUND OF THE INVENTION
There are currently two dominant ski binding systems for use in cross-country skiing and touring skiing.
These ski binding systems are based on the same principle in Figures la-d, where a ski boot sole 1 is shown fixed to the axis of rotation 2 in the front part of the sole 1 and in which a binding 3 comprises a locking mechanism based on locking mechanism the axis of rotation 2 of the binding 3, whereby the ski boot sole attachment to the ski.
Shoe sole 1 is rotatable about the rotation axis 2 of the axial center.
In Fig. Ib can be seen that the axis of rotation in the front of the big toe 4 and about 2.5 cm below the big toe 4 arranged.
The rotation axis is located about 1.4 cm above the upper surface of the ski.
The ski boot here uses a relatively thick, strong sole even in the big toe part and the front part of the midfoot area of the foot, resulting in a relatively stiff front part of the sole.
However, this is in conflict with the anatomy of the foot while performing a kick when walking and running, where the flexible and pliable part of the foot is precisely in this metatarsal and toe area.
When walking and running the foot in a continuous curve in the last part of the kick, it is bent, where, among other things, the calf muscles help to push the toes down and back - an important phase of the kick, which increases the length of the stride and the Acceleration.
Jogging and running shoes, for example, are therefore made with an extremely flexible and pliable sole in the metatarsal and toe area, in harmony with the anatomy of the foot.
The movement described above during the last part of the kick is not possible with the ski boot sole and ski binding.
As shown in Figures Ic and Id, there is too little flexibility in the front part of the sole to achieve a running type of movement in the front part of the midfoot area and the whole tip area during the execution of the shock.
Consequently, during the initial phase of execution, the kick will begin to rotate about the axis 2, as shown in FIG. I c.
From that moment and until the end of the kick, as shown in FIG. 1 d of the ski boot can be lifted off the ski due to its rotation about the axis 2, whereby its contact and force against the ski and the surface, so that the resulting force upwards relative to ski lose wishlist.
In addition, with the help of the built-in spring of the ski, handle-waxing part of the ski is picked up from the snow, meaning the grip disappears in that crucial part of the kick.
This means that the last and most important part of the kick, which could have provided increased acceleration and increased stride through the large muscle groups of calf, thigh and gluteal muscles, can not be used.
In short, the kick becomes less efficient because the movement is not completed, so of course, when walking and running.
The term " the movement needs " is widely used in sports.
It is generally believed that in order to achieve the best possible effect from a movement, it must be done in a natural way and not prematurely stopped.
Well-known examples are running and walking, golf, tennis, throwing, shot put, boxing, playing football, etc.
The above description of a Kegel kick in today's cross-country sports shows that there is one factor that is steadily increasing the use of arms in cross-country and long touring events today are often gained by drivers who do not perform a single kick, despite the fact That force in the arms usually only makes up about 20% of total leg strength. For the average skier who is able or willing to develop extreme strength in the arms is not, this type of extensive use of the arms is not an alternative.
The object of the invention is a ski binding and an associated sole for a ski boot, which offers the skier the opportunity to provide a longer and stronger impact.
This leads to a more efficient technique, higher speed and a longer resting phase, sliding and guiding each step in the diagonal step and skating.
This leads to a more efficient use of the large muscle groups, whereby the calf muscles come into play.
The object of the invention is also to provide a sole for a ski boot, which allows the skier good control of the skis in all conditions, especially downhill.
Another object of the invention is to provide a low profile binding and sole system.
Yet another object of the invention is that the binding of the fastening device does not touch the sidewalls of the ski slope, as this has a braking effect.
It is also an object of the invention to provide a ski boot sole and a ski binding, which provide a stable and reliable connection between the ski binding and ski boot sole.
It is also an object of the invention to reduce the weight of the ski boot and ski binding.
These objects are achieved by a sole for a shoe according to claim 1, a ski binding according to claim 9 and a system according to claim 16.
Further embodiments of the invention are defined in the dependent claims.
DESCRIPTION OF THE INVENTION
The present invention provides a ski boot sole which is more flexible than single in a jogging shoe in the longitudinal direction at the toe and midfoot of the sole, while providing the sole sufficient torsional and lateral stability to give skiers good control over the skis among all Conditions and especially downhill.
The present invention also provides a fastening device for the binding, which is preferably arranged in front of the toes, and clamps the sole downwards in the direction of the ski, with the result that the foot always presses against the surface during the entire sequence of execution of a kick for sure.
The preferably binding does not extend to the outside of the side parts of the shoe, which would result in that the binding engages the boot on the side of the toe, making the binding too wide and thus licking the side walls of the ski and causing a braking action.
In addition, a low-profile binding and sole system will result in better control of the ski and generally better balance, as the foot is thereby moved closer to the ski.
Sole for a ski boot
The invention comprises a fiber sole according to FIG. 3, with a transverse extension in the front part of the tip of the fiber sole. · '·· ·· ·· 9 9 9
The lengthening can be described as between 200% and 800% thicker than the sole and protruding on each side of the front part of the sole.
The fiber sole significantly determines the ski boot's mechanical properties.
The fiber sole covers the entire length of the shoe and the shoe bearing element, attached or glued to the upper part of the shoe.
Therefore, when reading this document, it is understood that, if one mentions the ski boot alone, will be made on the ski boot sole of the fiber.
The ski boot preferably also becomes an outsole, but this is thin and pliable so that it can not contribute mechanical properties to a significant extent to the ski boot sole.
The outsole is therefore to be considered as an addition to the ski boot sole according to the present invention.
Front part of the sole has a complementary form of binding of the guide channel 22, Fig.4. The fiber sole goes directly into the binding of the fastening device and the fiber sole thus determines the mechanical connection between ski boot and binding.
The invention utilizes the property of oriented fiber layers.
In an oriented fiber layer, all the fibers lie in one direction and the modulus of elasticity is typically twice as large as compared to the fibers in the fibers.
In combination with a change in the number of fibrous layers in different zones of the sole, this can be modeled in the construction of a ski boot sole in which the desired moduli of elasticity are modeled in different zones of the sole both in the longitudinal direction (x-uses direction) and transverse direction (y-direction In Fig. 3, the fiber sole may also be constructed with a layer of braided fibers or formed as a combination thereof.
In a braided fiber layer, the fibers are braided with the fibers at an angle of, for example, 15, 45 or 90 degrees to each other.
Layers of braided fibers have somewhat stiffer properties than oriented fibers.
The fiber sole is relatively flexible in the longitudinal direction of the sole, from the ball of the toe to the portion in front of the toes, while it is relatively stiff, from the heel to the ball of the foot.
At the same time the sole against twisting relatively rigid.
These relative terms are described in greater detail in the section of embodiments of the invention. Are defined.
A relatively thin and flat wear layer of rubber or synthetic material without guide channels on the underside of the fiber layer, Fig glued.
The invention provides a reduction of the sole weight between 65% and 80% in relation to the measured shoe soles known today. For a complete ski boot, the use of the fiber sole will provide for classic cross-country skiing for a weight reduction of 25% and 50% in comparison to today known boots.
The invention relates to a ski binding with a fastening device that is located in front of the toes in their entirety.
The binding has a guide channel that forms a complementary shape to the front portion of the fiber sole.
The guide channel 22, which is hatched in FIG. 4a, a front wall and two side walls, which may be conical or parallel, or may have other geometric shapes that have prevented the boat from moving forward or to the side.
In the front part of the side walls of the guide channel for receiving the sole extension of the end pieces transverse slots.
These prevent the boat from moving relative to the back to the binding.
Tension bar in the binding of the construction falls when the binding is closed and clamped at the trailing edge of the extension of the toe along the entire length of the extension, the sole being attached to the binding of the guide channel,
This ensures a stable connection between sole and binding.
The clamping rail can be reduced from the side over (ie in the y-direction) of the ski, as in the binding variant in FIG. 13, or it may be reduced from the leading edge of the binding together (ie, in the x direction) of the ski, as in FIG. 4.
The leading edges on the side of the binding are so high that they provide lateral support for attaching the sole after kicking off.
The invention gives the binding a weight reduction of the order of 30% to 60%, compared with today known solution.
Brine and bandage
The tolerance of the distance between the binding of the guide channel and the sole of the tip complementary shape is preferably between 0.01 mm and 3 mm.
The invention of the common construction and binding sole ensures that the foot always pushes on the ski over the entire kick phase, allowing for a more powerful and efficient kick.
Thus, the invention leads to increased use of the large muscle groups in the buttocks, thighs and calf muscles, as it is natural when the person moves forward in the field.
This will result in a light, relaxed and effortless step for the average skier, where the legs are well-developed extensor.
Extensive testing with prototypes based on the invention confirms the above with good results.

In Figure 2, a ski boot 10 is shown, the shoe upper part 1 1 and a ski boot sole 12th
Shoe sole 12 is believed to be attached to a ski binding 30 on a ski 2, which will be described in detail below.
As mentioned above, when reading this document to understand that when the ski boot sole or ski boot sole 12 is mentioned, it refers to the ski boot sole of the fiber.
The ski boot will preferably also have an outsole 13, but this is thin and pliable, so it does not contribute to 12 mechanical properties of the ski boot sole to a significant extent.
The outsole 13 is therefore considered as an addition to the ski boot sole 12.
Shoe sole 12 is divided into several zones or parts as shown in FIG. 2, a toe part TP under the toe area of the foot, a midfoot part MP under the midfoot area of the foot, a front part FP and a rear part RP.
Midfoot area MP is next to the toe part TP. The rear region extends from the RP midfoot region MP to a rear end R of the ski boot sole 12.
The rear part of the boot RP consists of a boot heel or heel area 14.
The front part FP from the toe part TP at the top F of the ski boot sole 12th
The front part FP has a ski binding attachment 20 which is connected to a ski binding, which is described in detail below.
In Fig. 3 it is shown that the ski binding attachment 20 has a plate-shaped sole tip 21 with a transverse extension 15 (y-direction).
The ski binding fastener 20 projects on the front of the boot upper 1 and has a width W20 that is less than the width of a ski slope.
The width of a ski lane is normally 60 mm to 80 mm. In the invention, the width of the ski binding is preferably smaller than the width of a ski slope, thereby preventing the ski binding attachment 20 from coming into contact with the side surfaces of the ski web.
Ski binding attachment 20 comprises a transverse extension, which is usually made of metal, carbon fiber, plastic, polycarbonate, POM, PEM, PET, aluminum or composite materials.
The aim of the extension is to position and hold the ski boot sole of the plate-shaped sole tip 21 securely in exactly the right position with respect to the ski binding in a simple manner.
In addition, the extension 15 provides support and stability for the sole when attached to the ski binding.
The extension 15 is preferably arranged in the front edge of the sole 12 and is preferably centered with respect to the ski sole 12.
The extension 15 may, for example, be in the form of a transverse element relative to the front part FP of the ski boot sole 30 and slightly protruded over the sides of the shoe sole 12 of the front part FP. The length of the extension 15 may, for example, between 5 mm and 80 mm, preferably between 20 mm and 60 mm.
Between 1 mm and 10 mm, the diameter of the extension 15 on the outside of the plate-shaped sole tip 21 may be, for example, preferably between 1 mm and 4 mm.
The thickness of the extension in the ski boot sole between the side walls of the guide channel, for example, between 1 mm and 16 mm, preferably between 2 mm and 8 mm.
The extension 15 and the plate-shaped sole tip 21 will ensure the stability of the sole when it is fastened in the ski, especially in the case of backward and lateral movement of the sole relative to the ski binding.
In an alternative embodiment, the plate-shaped sole tip 21 has arranged an oval hole on or in the vicinity of 12 longitudinal center axis I. The sole
The sole 12 comprises a material in which the longitudinal elasticity in the x-direction, the transverse elasticity in the y-direction and torsional rigidity of the sole 12 are determined by the properties of the fiber layer 12.
The decisive factor for the sole 12 stiffness and / or flexibility in the x-direction and y-direction is determined by the number of fiber layers in the construction of the sole 12 together with the orientation of the fibers in the sole different parts / zones.
Shoe sole of the geometric shape in the different zones of the ski boot sole is also a crucial factor for the flexibility and rigidity.
In general, the rule for the fibers, which is the modulus of elasticity along the fibers is twice that for the fibers.
The outsole of the ski boot upper is preferably formed without grooves and preferably comprises a thin wear layer 13 made of rubber or the like, with a modulus of elasticity E between 10 MPa and 200 MPa. A typical range of values for the modulus of elasticity for different fibers:
Carbon composite, oriented and woven prepreg 45 degrees with modulus between 20 GPa and 190 GPa and glass fiber between 60 GPa and 80 GPa.
The sole fiber layer 12 can be adapted to the shape of the foot and the weight of the user.
In the invention, the fiber layer 12 becomes a composite material comprising layers of carbon fiber, for example oriented carbon fibers or carbon fiber of the prepreg type, in which the layers are stacked and adhered together or fixed with a resin, such as epoxy.
Typical suppliers of oriented carbon fiber layers and woven carbon fiber prepreg are: Zoltek (http://www.zoltek.com/) and Hexcel (http://www.hexcel.com/).
Alternatively, the fibrous layer 12 may include glass fibers, such as oriented glass fibers or a combination of carbon fibers and glass fibers, natural fibers, and various types of synthetic fibers.
In the present invention, the rear part RP is stiff in the longitudinal direction (x-direction) and the transverse direction (y-direction) as well as torsionally rigid in the longitudinal direction (about the x-axis).
The front part FP is flexible / flexible rigid in the longitudinal direction and rigid in the transverse direction as well as rotating in the longitudinal direction.
Metatarsal region MP is flexible in the longitudinal direction (x-direction), stiff in the transverse direction (y-direction) and also rotational in the longitudinal direction is rigid.
The toe part TP is flexible in the longitudinal direction (x-direction), stiff in the transverse direction (y-direction) and also rotational in the longitudinal direction (about the x-axis) is rigid.
A stiff ski boot sole will therefore be considered in the longitudinal direction (x-direction) by an adult of about 75 kg, if the rigid sole has the following rigidity:
A force of 12 Newton at 20 mm deflection and a force of 120 Newton at 85 mm deflection and a torque of 1 Nm with a rotation angle of 5 degrees and a torque of 20 Nm with a rotation angle of 40 degrees.
Accordingly, a flexible ski boot sole is considered to be flexible in the longitudinal direction (x-direction) by an adult of about 75 kg, if the sole has the following rigidity:
A force of 1 Newton with 20 mm deflection and a force of 32 Newton at 85 mm deflection and a torque of 0.4 Nm with a rotation angle of 5 degrees and a torque of 10 Nm with a rotation angle of 40 degrees.
The deflections and torsion angles given above are found by taking force / strain measurements according to standard deflection measurement techniques known to those skilled in the art.
The deflection results given above were found, a sole clamped with a bench and with the sole force exerted at a length L = 140 mm from the nip and the deflection caused by the force at L = 140 mm was measured.
Similarly, the torsion angle was measured clamped by a single found on a bench and a torque applied to the sole at a length L = 140 mm from the nip and the angle of rotation of the sole caused by the torque at L - 140 mm.
It should be noted that whether a ski boot sole is considered rigid or pliable is also a subjective assessment that additionally depends, among other things, on the weight of the skier and whether the ski boot / bindings are used on skis for skating, classic lang, telemark etc.
Therefore, despite the stated absolute physical measurements as defining flexibility and stiffness, it should be noted that the terms " rigid " and " flexible " as used herein should be interpreted as " rigidly perceived " and " so flexibly perceived " depending on the weight of the skier, the size of the ski boot, the type of ski discipline, etc.
The same result as described above can be obtained with woven carbon fiber or glass cloth, or in combinations thereof.
There are various tissue configurations and angles between the fibers in which, for example, a 45 degree angle between the fibers is used.
It should also be noted that bending stiff / flexible in the longitudinal direction as bending rigid / flexible to transverse to understand deflection about an axis in the y direction.
Correspondingly bend rigid / flexible in the transverse direction as bending rigid / flexible to deflecting about an axis in the longitudinal direction x-direction to be understood.
In a longitudinal direction torsionally stiff and torsionally stiff to be understood to a longitudinal axis in the x direction.
Table 1 below shows an example of the orientation of the fiber layers 12.
The fibers can be aligned in the longitudinal direction, that is to say parallel to the longitudinal center axis I in the transverse direction, that is to say perpendicular to the central axis I or in a diagonal direction, ie at an angle of generally 30 [deg.], 45 [deg.] Or 60 [. deg.] in the direction of the I-axis.
Table 1: Example of the number of layers and the orientation of the fiber layers 12 in a sole.
As an alternative to oriented fibers, as in the above table woven fibers can be used, for example prepregs with a 45 degree angle between the fibers.
These are somewhat stiffer and can be less total than layers in the table above.
Depending on the thickness of a layer provided by the manufacturer, the above-mentioned number of layers in the various layers may be increased, maintained or reduced.
The examples of the various layers in the sole are shown in FIG. 10 and in Table 1.
Here it can be seen that layer Nos. 2 and 5, which are for all zones of the sole, FP, TP, MP and RP, creating a continuous sole.
It should also be noted that the layers partially overlap, as shown in FIG. 10, ie some layers continue partially into the adjacent sole portion, creating a stepwise change in the flexibility of the sole.
Ski binding 30 will now be described with reference to FIGS. 4a-b, figs. 5a-b and Fig. 6. Ski binding 30 comprises a base plate 31.
The base plate 31 is attached to the upper surface of the ski in a manner known to those skilled in the art.
The base plate has tips that increase the friction between the base plate 31 and wear layer 13 of rubber or similar material.
Ski binding 30 has a locking mechanism 35 which is fixed to the base plate 31.
The base plate of the locking mechanism 35 is disposed in front of the base plate 31.
The ski binding 30 has a guide channel 22 which also has a complementary shape to the ski binding attachment of the plate-shaped sole tip 21 on the front of the ski boot sole.
The guide channel 22 is bounded by a front wall 24 and the two side walls 33, all of which project above the base plate 31.
The guide channel 22 forms the surface on the base plate 31 between the front wall 24 and the side walls 33 at the end of the binding 30 under the ski boot sole 12 may be a friction pattern or friction surface.
The ski binding 30 further comprises two slots 32 in the respective side walls 33 of the guide channel.
The guide channel 22 has a shape that is suitable for receiving the extension 15 in the front part of the ski binding attachment 20 in the sole 12.
The ski binding 30 continues a ski boot facility 40.
The ski boot attachment 40 comprises a clamping bar 41 and a clamping rail 27.
This is rotatable and connected to the base plate 31.
The ski boot system 40 can be made as a part.
In an open position, the locking plate 25 will be inclined forwards, they draw with lever arm 26, which in turn is attached to the clamping bar 41, whereby the clamping rail 27 opens.
The lever arm 26 is mounted between clamping arm 41 and locking plate 25.
Clamping arm 41 and detent plate 25 mounted in both pivot points independently of each other on the base plate 31.
In the open position of the plate-shaped sole tip 21 on a flexible ski boot sole 12 with associated extension 15 in a position to be inserted into the guide channel 22, and the ends of the extension 15 down into the slots 32 in the side walls 33 of the base plate 31 with the result in that the extension 15 is inserted into the same slot 32 of the tension rod 27 then used for locking and closing the ski binding attachment 20 to the ski binding 30.
Clamps 41 key slots 28 in which a spacer can be inserted, which must be clamped after completion of the kick between the front part of the shoe upper part 1 and the key slot 28 for customization the return point of the shoe, after the end of the kick ,
The spacer has an elongated shape and may have at most the same length as the distance between the two side walls 33.
In Fig. 6 of the ski boot sole 12 ski binding system 20 is shown.
It can be seen that side walls 33 with a laterally stabilizing effect, the sole 12 and the ski binding 20 fastening seat in the specified channel 22 and the slot 32 on the ski binding 30th
It should be noted that the side walls 33 in Fig. 6 are located in front of the toe part TP on the sole (ie, when the sole 12 is attached to the binding 30).
Nevertheless, it is conceivable that the side walls may easily extend to the side of the boot, but not so far into the toe part TP of the ski boot sole 12 that the side wall 33 terminates on the outside of the toe (ie the outside of the big toe and little toe , each on each side of the foot) of a wearer of the ski boot.
The base plate 31 has side walls 33 of sufficient height to prevent lateral movement of the floor / boat during the execution of a kick, thereby providing good control over the skis.
In the folded position, the locking plate 25 is recessed in the binding, so that objects are unable to hit or open the lock, or prevent snow from entering the binding mechanism.
The terminal block 27 will be recessed in a slot 32, causing transverse movements.
The clamping bar 27 may be formed with the same diameter as extension 15 as shown in FIG. 8A.
In the closed configuration of the clamping bar 27 is locked so that they can not be opened.
The locking plate 25 for binding is located in the leading edge of the binding and preferably centered, but this is not necessary.
The locking plate 25 is normally made of metal, aluminum,
Plastic, spring steel, carbon fiber, glass fiber, long glass fiber, thermoplastic polymer, POM, PEM, PET, polyamide, polyamide composite, semiaromatic materials, plastic fiber, rubber or composite materials.
In a closed state, the locking plate 25 will preferably be recessed in the binding, but not necessarily.
With the terminal block 27, the more the binding is locked applied The greater force.
The ski binding of the base plate 31 includes a base as well as a binding housing 34 which secures and protects internal components.
The base plate 31 is usually glued directly to the ski, directly attached to a ski with 2-5 screws and screw holes or on a plate that glued or firmly attached to the ski in another way.
The base plate 31 may be made of a metal, preferably a light metal, such as aluminum, strong and light plastic materials, carbon fiber, glass fiber, long glass fiber, thermoplastic polymer, POM, PEM, PET, polyamides, polyamide composite partially aromatic materials, plastic fiber, rubber or composite materials, to endure the cold and wear it.
The materials in the bond usually have a tensile strength of up to 300 MPa and stiffness up to 30,000 MPa. The bonding of the components are molded or made in one device.
The clamping bar 27, clamp 41 and locking plate 25 will typically be made of plastic materials, carbon fiber, glass fiber, long fiberglass, thermoplastic, polymeric, POM, PEM, PET, polyamides, polyamide composite semi-aromatic materials, plastic fiber, rubber or composites.
Between the locking plate 25 and clamping arm 41, a lever arm 26 is arranged to transmit force between the locking plate 25 and clamping arm 41.
The lever arm 26 can ensure a curvature, the locking of the extension 15.
The lever arm can be made of the same materials as the base plate 31, but also of metal.
The rotatable connection points between lever arm 26 and locking plate 25 and clamping arm 41 are connected by axle holes through which metallic cotter pins pass, for example, to ensure that they remain in the correct position. - - - - * ··
Other methods may also be envisaged for a connection between these parts, such as clamp connections or connections between them, which will be known to a person skilled in the art.
Figure 7 shows that the binding 30 will also have a heel friction layer 16 over the ski.
The heel friction layer 16 supports the sole 12 14 heel.
The heel friction layer 16 will provide the friction between ski 2 and 13 rubber layer and fiber layer 12 so as to keep the boat laterally stable.
The heel friction layer 16 can come in several versions to meet the individual needs of the skier.
The height differences in the heel friction layer 16 may be between 0.1 mm and 1.5 cm.
The heel friction layer can be separated from the base plate 31, or the base plate can cover for the entire ski area from the front 31 at the heel area.
Under the foot, ie in the toe part TP and / or midfoot MP, the base plate should be wider than the ski, for example, 0.2-3 cm on each side of the ski to improve stability, while skiing downhill.
The movement of the sole 12 with respect to the ski binding 30 is shown in the figures. 8a to 8d, where the toes touch the baseplate in each part of the kick process.
As shown in FIG. 8b, during the initial stage of execution of the kick the rear part RP is lifted from the binding and ski 30, while most of the mid-foot part MP and the whole toe part TP and the entire front end part FP of the sole are to contact the binding 30.
This movement is achieved due to the flexibility of the midfoot part Mp.
In a subsequent part of the kick, as shown in Fig. 8c, the rear part RP is further raised.
Here, all or most of the midfoot part Mp is raised from the base plate 3, but press the toes in contact with the ski and against the surface.
This movement is achieved due to the flexibility of the midfoot part MP and the toe part TP.
In a final part of the kick, as shown in Fig. 8d, the entirety of the middle foot part MP and all or most of the toe part TP are lifted off the base plate 31.
This movement is achieved due to the flexibility of the midfoot part MP and the toe part TP, and also because of the binding 30, as it pushes the ski boot sole down in the front edge of the shoe upper part 1.
It should be noted in Fig. 8d that the distance from the underside of the toe in the upper part of the shoe 1 1 to the base plate 31 is not increased, or less than in the sole according to the prior art, as shown in Figs. be because the sole in the toe area is firmly clamped to the binding.
In figs. 8b-8d a point in the sole shown.
This point shows the pressure point or the rearmost part of the sole that is in contact with the binding during the execution of a kick.
It is clear that this pressure point moves continuously on the ski from the back of the midfoot MP all the way forward to the front part of the toe part TP while performing a kick.
We now see Fig.9. Here it can be seen that the flexibility in the longitudinal direction of the sole 12 is relatively low (ie, the modulus of elasticity is high) for the front part FP and RP rear part, while the flexibility in the longitudinal direction of the sole 12 for the toe part TP and the midfoot part MP is relatively high (ie, the modulus of elasticity is low).
We refer to the picture. 8c shows the other properties of the ski binding.
Ski binding 30 may have a shape friction pattern 29 in the base plate 31.
This friction mask 29 may be formed either in the base plate 31 or a friction pattern layer that is glued or fixed to the base plate 31.
The friction pattern 16 with spikes can also be under the heel.
We refer to the picture. 10 illustrates the fiber orientation and fiber layers in the sole 12.
We refer to the picture. 1 1 that shows the attachment between the extension 15 and ski boot sole 12th
Extension 15 is covered by ski boot sole 12 and glued or fused together, so that the extension 15 formed in the ski boot sole 12.
Fabric 17 may be attached to the underside of the sole tip extension 15 and the top of the sole 12.
Fabric wrapped around the front of the sole can be liquid crystal polymer, aromatic polyester, aramid, kevlar, carbon fiber, synthetic fiber, polyester fabric covered with thermoplastic polyurethane / PVC or other fabric that wraps in plastic.
Alternative solutions
In the above description of a coal extension 34 is indicated prior to attachment of the ski binding 20.
This extension 34 may for example be made of carbon fibers, nanofiber, plastic, metal, polymer, POM, PEM, PET, Teflon or composite materials.
Figs. Figures 12a-12b show another solution for binding with a clamping device in an open and closed position. Guide channel 22, which rises with the plate-shaped sole tip 21 clearly in the diagram fits together.
Figure 13 shows a more complex solution of the binding binding device which can be opened and closed by a ski pole.
Fig. 14 shows an open and closed mechanism for a clamping strip 27 on a ski binding which is intended to be actuated by a ski pole for opening and closing the mechanism.
With reference to FIGS. 15a-b and 16a-ba ski binding, a locking device 42 is shown having a transverse arm 44 and two side arms 43 secured to each end of the cross arm 44.
The side arms 43 are rotatable on the ski binding 30, whereby the entire locking device is fixed relative to the base plate 31.
Figures 15a and 16a show the locking device 42 in an open position while Figures 15b and 16b of the locking device 42 are in a position where a ski boot is securely locked on the ski (the ski boot is not shown in the figures).
The locking means 42 further includes one or more cam members 46 which is rotatable together with the side arms 43 when the locking means 42 is rotated by a user.
The cam members 46 are mounted below one end of the rotatable clamping arm 41 with the result that when the locking means 42 are rotated in the direction of rotation R, as shown in Fig. 16A, the cam member 46 locks the clamping arm so that the opposite end 41 clamping bar 27 clamping arm is clamped down against the front part FP on a ski boot sole 12 (not shown), which is located in the ski binding 30, whereby the ski boot sole 12 in place in the ski-holding 30 binding.
When the locking device 42 is arranged in the locking position, the transverse arm will preferably be arranged in a groove 45 in the clamping legs 41, as indicated in the figures. In the locking position of the locking device, the cam member 46 is preferably rotated at the equilibrium position (ie, the vertical position) so that when an attempt is made, the clamping leg 41, and thus the tension bar 27, rotate with the locking device 42 in the locking position , the force of the clamping arm 41 on the cam member 46 is trying to rotate the cam member 46 and thereby the locking device 42 further in the direction of rotation R, ie the cross arm 44 terminals even harder on the clamping arm 41 and thus the terminal block 27 clamping harder on the ski boot sole, which is firmly locked in the ski binding 30.
As can be seen in the figures above, the ski boot sole 12 is fastened to the ski binding 30 by the clamping strip 27. Clamping shoe sole 12 is plate-shaped sole tip 21 fastened to the base plate 31.
In order to more securely connect the ski boot of the ski boot sole 12 in the ski binding 30, the ski boot sole 12 can additionally be provided with an extension over the plate-shaped sole tip 15, which are provided and protruding, so that the extension 15 fits into slots 32 in the ski binding of the 30th Side walls 32.
The terminal block 27 fits into the slots 32, whereby the plate-shaped sole tip of the extension 1 against the base plate 31 Spann.
