Definitions
- the present invention relates to a ski boot arranged for releasable attachment to a ski by means of a ski binding.
- the ski boot comprises an outer sole, an upper part and an attachment member, the attachment member being arranged to match and cooperate with a locking mechanism on the ski binding.
- the front part of the ski boot is attached to the ski by means of a ski binding, as the ski binding and the ski boot are arranged to interact in such way that the heel can be lifted from the ski.
- the skiing experience to a large degree is affected by where and how the ski boot is attached to a ski by a ski binding.
- the skiing experience is also affected to a large degree by parameters such as the bendability of the ski boot, torsion stiffness and ability to support the foot.
- parameters such as the bendability of the ski boot, torsion stiffness and ability to support the foot.
- the bendability of the ski boot, torsion stiffness and ability to support the foot will vary in such a degree that optimized special equipment has been developed for each discipline.
- a higher gearing could be advantageous in a course which is relatively flat and/or under particularly quick snow conditions. It could become harder to keep the same frequency relative to a neutral gearing, but the developed power and the gliding length for each kick could become considerably larger, resulting in a considerably higher speed. The top speed could also become higher.
- a lower gearing could be beneficial in a course which is relatively hilly and/or under particularly slow and heavy snow conditions. It could become easier to keep the same or higher frequency relative to a neutral gearing, and the developed power and the gliding length for each kick could become smaller, however it would be considerably easier to maintain the technique in steep terrain, and at the same time be able to accelerate faster when the terrain flattens out over hilltops. The top speed could become lower, but this will be of minor importance in a course which is relatively hilly and/or under slow and heavy snow conditions.
- EP2465371 Al relates to a solution in which two steel pins are releasably mounted on the front part of a ski boot by means of a fixture which for instance can be fastened with screws in the outer sole of the ski boot.
- the purpose of this is primarily that the steel pins, which are subject to wear and tear, may be easily replaced.
- EP2465371 Al also mentions that the position of the steel pins in longitudinal direction may be adapted based on the user's preferences, without discussing these preferences to any certain degree. According to EP2465371 Al the steel pins have been asymmetrically mounted on the fixture, as turning of the fixture will move the steel pins forwards or backwards, respectiveley.
- the fixture may be slid backwards or forwards, as the fixture is mounted on the outer sole by screws.
- the outer sole comprises a number of screw holes, and depending on which holes that are used, the fixture could together with the steel pins be moved forwards or backwards.
- the fixture forms in itself a part of the walking surface.
- Fig. 1 shows a perspective view of an embodiment of the present invention
- Fig. 2 shows an exploded view with details of an embodiment of the present invention
- Figs. 3 a and 3b show a top face and bottom face plan view of an embodiment of the present invention
- Fig. 4a shows a cross-section of an outer sole according to an embodiment of the present invention along the section indicated as A- A in Figure 3 a
- Fig. 4b shows a cross-section of an outer sole according to an embodiment of the present invention along the section indicated as B-B in Figure 4a,
- Figure 1 shows an outer sole 6 of a ski boot, where a fastening pin 2 can assume three different positions 3; 4; 5 in longitudinal direction, where the positions are selected from the group comprising a neutral position 4 with a neutral gearing, one or more positions 3 with heavier gearing, and/or one or more positions 5 with lighter gearing.
- Figure 1 shows the fastening pin 2 arranged in the heaviest position.
- a ski boot 1 is further provided 1 with an outer sole 6 comprising two longitudinal and parallel outer sole ridges 7 which between them form a longitudinal recess 8.
- outer sole 6 comprising two longitudinal and parallel outer sole ridges 7 which between them form a longitudinal recess 8.
- Each of the longitudinal and parallel outer sole ridges 7 have been arranged with a number of fastening points which define and correspond with the different positions 3; 4; 5 which the fastening pin 2 can assume.
- the fastening points can be selected from the group comprising holes, grooves, recesses and pins.
- the fastening points can be arranged in pairs transversal to the longitudinal direction of the outer sole 6 in the above longitudinal and parallel outer sole ridges 7.
- Figure 2 shows a view of an outer sole 6 corresponding to the one shown in figure 1, but from a different perspective and with fastening pin 2 and two fixtures 8 shown in an expanded condition.
- two fixtures 8 are provided which may be arranged in separate grooves 9 in each of the outer sole ridges 7 from the inside of the outer sole 7.
- the fixtures 8 are arranged prior to the mounting of the middle sole and upper part of the ski boot, such that the fixtures 8 are hard mounted when the ski boot is finalized.
- the fixtures 7 could also be contemplated, for example an embodiment in which the outer sole ridges 7 comprise grooves wherein the fixtures 8 may be introduced from the outside of the outer sole 6, for example in grooves that are arranged on the bottom side or front side (not shown) of the outer sole back 7. Regardless of how or wherefrom the fixtures 7 are arranged, the fixtures 7, according to these embodiments of the present invention, will be locked when the fastening pin 2 has been mounted in one of the hole pairs 3; 4; 5. Alternatively, the fixtures 7 may be molded onto the outer sole 6, each in its separate outer sole back 7, such that the fastening pin 2 is not required to secure that the fixtures 7 are held in place.
- the fastening pin 2 shown in figure 2 comprises threads and may further comprise a gasket, for example of the NylocTM type, forming a check nut effect.
- the fixtures may comprise threads that are completely or partly coated with a NylocTM type material, thus to achieve a check nut effect.
- Other locking methods could also be used, for instance glue (LoctiteTM or other types of glue), or press fit, where the pin is pressed in such that it stays, and is knocked out again with a suitable tool.
- the fastening pin 2 shown in figure 2 comprises a head of the umbraco type, whereas other screw grooves / heads (straight, cross, Torx or similar) may also be used within the scope and spirit of the invention.
- the one end of the fastening pin 2 comprises a groove which matches the hole 3; 4; 5 in which it should be introduced, whereas the other end comprises threads and the above screw head.
- Other variants may just as well be used, for example threads in the end farthest from the head, while a NylocTM type gasket is arranged around the end closest to the head etc.
- Fig. 3a shows the outer sole seen directly from above (from the inside), groove 9 being shown into which the fixtures 8 easily can be introduced prior to the mounting of middle sole and upper part. As previously mentioned, fixtures 8 may also be molded into the outer sole 6.
- Fig. 3b shows the outer sole seen directly from below (from the outside), the fastening pin 2 being arranged in the hole pair 3, i.e. in the heaviest position.
- hole pair 3 may provide a gearing which is heavier than neutral
- hole pair 4 provides a neutral gearing
- the hole pair 5 provides a lighter gearing.
- position 3 may be neutral
- positions 4 and 5 provide two lighter gearings, or 3 and 4 are heavier than the neutral position 5, etc.
- Fig. 3b shows the outer sole seen directly from below (from the outside), the fastening pin 2 being arranged in the hole pair 3, i.e. in the heaviest position.
- hole pair 3 may provide a gearing which is heavier than neutral
- hole pair 4 provides a neutral gearing
- the hole pair 5 provides a
- FIG. 4a shows the section A- A indicated in fig. 3a.
- the angles and distances that are indicated are relevant for the established NNN® standard from Rottefella®. It is understood that these are not limiting to the scope and spirit of the invention, as other standards (current or future) could require other angles and distances. With respect to the distance between the positions/hole pairs 3; 4; 5, a greater distance will imply a larger difference between the gearings and vice versa.
- Fig. 4a shows the section B-B indicated in fig. 4a.
- the indicated distance between the outer sole ridges 7 is relevant for the established NNN® standard from Rottefella®. It is understood that this is not limiting to the scope and spirit of the invention, as other standards (current or future) could require other distances.
- the fixtures 8, fastening pin 2 and outer sole ridges 7 are cut-away.
- a steel material is most commonly used for such attachment points. Steel is a ductile, strong and durable material which therefore constitutes an excellent choice for such attachment points. It should be understood that other materials, metals and alloys may also be used. A relevant and alternative metal is titanium, which is preferred by some due to its light weight. Titanium is however worn considerably faster than the relevant steel alloys, and are at the same time more prone to breakage due to its brittleness.
- ski boot and binding systems which offer the opportunity to select and vary the gearing
- the flexor in the binding may have to be made thicker or thinner depending on which position one selects.
- the walking or running frequency could also be of importance as to which flexor softness/stiffness and what flexor-response one selects.
- a heavier gearing (lower frequency) a flexor with a slower response could be preferred, such that the ski does not return too quickly to its initial position after each stroke or kick.
- neutral position refers in principle to the position in which one according to the NNN standard has positioned conventional fastening pins or steel pins. This position is per se not exact since it to a large degree is based on extensive testing and experimenting. What could be called a neutral position will to some extent vary based on which standard that is used and a large number of parameters, such as sole thickness, sole stiffness, general boot construction, boot and sole materials, binding system, flexor stiffness, flexor qualities (for example bending stiffness versus rotational angle around the attachment point of the ski boot ), etc. Even if the term “neutral position” may seem somewhat vague, it turns out that most ski boot manufacturers have located the fastening member in what by the skier would be perceived as the neutral position.
- one can according to another aspect of the invention provide holes which form at least two different positions 3; 4; 5 in vertical direction, the ski boot being able to be lifted in vertical direction in addition to, or optionally instead of, being able to be repositioned in the longitudinal direction. It has been found that one can improve the skiing experience, power consumption and balance under some snow conditions by lifting up the front of the ski boot relative to the heel. Wedge-shaped spacers which are arranged between the binding and ski are used to achieve this.
- Another way to achieve a similar effect could be to move the fastening pin farther from the bottom side of the ski boot.
- the net effect of moving the fastening pin in vertical direction could correspond to or strengthen the effect of moving the fastening pin in longitudinal direction. Moving the fastening pin somewhat down could for example correspond to moving the fastening pin somewhat backwards etc.
