Description
CONNECTION SYSTEM FOR SKI BINDINGS.
TECHNICAL FIELD OF THE INVENTION
The present invention concerns a system suited to be used for skiing.
In particular, the present invention concerns a connection system for ski bindings.
DESCRIPTION OF THE STATE OF THE ART
The use of suitable equipment is known in the field of sports activities in the snow.
In particular for skiing, as is known, special boards, commonly called simply skis, are used, to which the footwear used by the skier/user is fixed.
Skiing includes different disciplines, depending on the ground where it is practised, the routes and the time of year.
Thus, for example, various disciplines are known, ranging from the most famous ones, like alpine skiing (downhill skiing) and nordic skiing, to special and niche disciplines like ski mountaineering, free ride and free style.
Different pieces of equipment that enhance and facilitate the required sports movements have been developed over the years for the practice of the different disciplines.
The market offers these items, thus allowing users to practise their favourite discipline in optimal conditions.
Consequently, already from his/her first experiences the skier uses his/her own or rented specialist items.
A typical piece of equipment that is common to the various disciplines comprises a ski provided with an interface element, commonly called binding, suited to accommodate in a fixed or removable manner the sole of the footwear item worn by the user.
In order to improve the characteristics of the unit comprising the ski and the binding, in the recent past the use of a raising plate has been introduced, said raising plate being sometimes integrated in the ski itself but more generally being applied to the ski by fixing it thereto with a screw. The raising plate spaces the boot from the supporting plane of the ski, thus increasing the lever arm that is useful to modify the attitude of the ski, making it easier for the skier to make curves and allowing him/her to incline his/her legs to a greater extent without the boots coming in contact with the snow.
Also the boots have been developed for the different disciplines, with special
differences in the case of ski mountaineering, for which lightness is a priority and specific systems for coupling to the binding are provided, and in the case of free ride, for which the rear rotation of the boot's leg is allowed.
The boots used for downhill skiing has characteristics that are extremely comfort-oriented in the medium and low-end models, while they are performance-oriented in the competition models, in which more rigid structures and/or materials are used, as well as volumes with shapes adhering to the foot's anatomy.
A first drawback connected to the equipment of the known type is represented by the considerable costs that a user has to bear when he/she intends to practise various disciplines. In this case, he/she will need to buy specific equipment for each individual discipline practised.
This determines a high cost for a user who wishes to practise various disciplines. Analogously, the same drawback arises for equipment rental companies that are forced to invest in different types of equiment for each specialist discipline or, alternatively, to neglect a niche of potential customers fond of special disciplines, such as, in fact, ski mountaineering, free ride or free style.
Actually, the market niche constituted by the skier who occasionally practises minor ski disciplines substantially does not exist, since the personal investment required for the specific equipment is too high, and analogously, for the same reason, there are only few rental companies that offer this type of equipment. Another drawback connected to the equipment of the known type is constituted by their overall dimensions and by the consequent need to have sufficient space to store them, in particular for rental companies.
It is the object of the present invention to at least partially overcome the drawbacks of the known art.
In particular, it is one object of the invention to provide a system that allows a user to practise several disciplines at a limited cost.
It is another object of the invention to provide a system that makes it easier for rental companies to prepare versatile pieces of equipment suited to satisfy the needs of most of the skiers who practise the different skiing disciplines.
It is a further object of the invention to provide a system that makes it possible to reduce the quantity of pieces of equipment needed by a user who practises several disciplines or by rental companies that intend to meet the demand of the largest possible number of users who practise the different sports disciplines.
It is another object of the invention to provide a system that makes it possible to reduce the equipment storage spaces for a user who practises several disciplines or for rental companies that want to meet the demand of the largest possible number of users practising the different sports disciplines.

DETAILED DESCRIPTION OF THE PRESENT INVENTION
Although the present invention is described below with reference to its embodiments illustrated in the drawings, the present invention is not limited to the embodiments described below and illustrated in the drawings. On the contrary, the embodiments described and illustrated herein clarify some aspects of the present invention, the scope of which is defined in the claims.
The connection system that is the subject of the invention described below is particularly suitable for direct application to a ski.
It should however be pointed out that the present invention is not limited to direct application to a ski. On the contrary, other elements may be interposed between the connection system of the invention and the ski, like for example raising plates of the type commonly used in the known sports disciplines.
A connection system 1 for ski bindings A according to a first preferred embodiment of the invention is described with reference to Figures from 1 to 3. The connection system 1 according to the invention is suited to be associated with a ski S, represented with dotted lines in the figures, and is suited to accommodate a ski binding A, also represented with dotted lines and only in Figure 3. Both the ski S and the binding A can be known products that are easily available on the market. The binding A shown in Figure 3, in particular, is of the type used in alpine skiing and substantially comprises two stop elements Al and A2 suited to accommodate and be coupled respectively with the tip and the heel of a sole F of a boot, the sole F being represented separated from the rest of the boot for the sake of description simplicity.
In the known art, the binding A is typically fixed to the ski S directly, or possibly with the interposition of a raising plate.
According to the present invention, instead, the connection system 1 is advantageously interposed between the binding A and the ski S.
Thus, always according to the present invention, the connection system 1 can be fixed to the ski S, while the binding A in turn is fixed to the connection system 1, as will be better explained below.
The connection system 1 according to the invention, when provided with suitable coupling/releasing means 20, allows the user to use the unit made up of the ski S, the binding A and the connection system 1 both as a rigid system, for example for the practice of alpine skiing, free ride or free style, and as a system that gives
the foot degrees of freedom suited to allow the user to walk, for example for practising nordic skiing or ski mountaineering.
The connection system 1 preferably comprises a first element 2, or first plate, suited to be connected to the ski S, and a second element 3, or second plate, suited to accommodate the binding A.
The first and the second plate 2, 3 preferably develop longitudinally along a main axis X.
The connection of the first plate 2 to the ski S is obtained through first connection means 4. In the embodiment illustrated herein, said first connection means 4 comprise appropriate fixing screws, not illustrated in the figure, arranged so that they pass through suitable holes 5 made in the first plate 2 and are screwed into and engaged with the underlying ski S.
In variant embodiments of the invention, said first connection means may be of a different type, for example they may be glueing means, jointing systems, fixing systems with rivets etc.
The connection of the binding A to the second plate 3 is obtained through second connection means 6. In the embodiment illustrated herein, said second connection means 6 comprise suitable fixing screws, not shown in the figure, arranged so that they pass through suitable pairs of holes 7a made in the binding A and are screwed into and engaged with corresponding pairs of holes 8a made in the second plate 3.
It should be noted that the second plate 3 can be advantageously provided with further pairs of holes 8b-8e arranged at different distances and suited to allow the connection of bindings having different sizes.
In variant embodiments of the invention, said second connection means may be of a different type, for example they may be glueing means, jointing systems, fixing means with rivets, etc.
Between the first and the second plate 2, 3 there are articulation means, indicated as a whole by 10, suited to allow the second plate 3 to be moved with respect to the first plate 2, as will be explained in greater detail below and as illustrated by way of example in Figures 5, 6 and 7.
The articulation means 10 comprise a first articulation element 1 1, or first connecting rod, and a second articulation element 12, or second connecting rod. The first and the second connecting rods 11, 12 are arranged so that they are substantially parallel to each other and are hinged respectively to the first and the
second plate 2, 3 with their ends.
The connecting rods 1 1, 12 are hinged to the first and the second plate 2, 3 on respective articulation pins 13, 14.
The articulation pins 13, 14 are preferably aligned along a secondary axis Y. Said secondary axis Y is transversal to the main axis X of the plates 2, 3. Said secondary axis Y is preferably perpendicular to the main axis X of the plates 2, 3. Preferably, the first articulation pin 13 associated with the first plate 2 is arranged on a supporting element 44 fixed to the first plate 2 and to the ski, preferably through screws.
Preferably, the second articulation pin 14 associated with the second plate 3 is arranged so that it passes through two supporting holes 16a, 16b made in the second plate 3.
According to a variant embodiment, the articulation means may comprise a single articulation element preferably arranged in a centre position and hinged to the two plates at its ends.
In further embodiments of the invention, the articulation means may comprise more than two articulation elements, preferably arranged parallel to each other, hinged to the two plates at their ends.
The connection system 1 furthermore comprises, as previously explained, coupling/releasing means 20.
The coupling/releasing means 20 make it possible to arrange the connection system 1 in a first rigid configuration, that is, with the second plate 3 in a stable and fixed position with respect to the first plate 2, and in a second configuration in which the second plate 3 can assume different operating positions with respect to the first plate 2.
The coupling/releasing means 20 comprise a plurality of coupling elements 21 associated with the first plate 2 and corresponding projecting elements 22 associated with the second plate 3.
In the embodiment illustrated herein, the coupling elements 21 and the corresponding projecting elements 22 are eight, divided in two groups including four elements each and positioned towards the ends of the first and the second plate 2, 3.
It is evident that in variant embodiments the number and the position of said coupling elements and of the corresponding projecting elements may vary and be conveniently selected to guarantee the desired characteristics of the connection
device in terms of tightness.
Again, in a variant embodiment of the invention the coupling elements may be associated with the second plate and corresponding projecting elements may be associated with the first plate.
It is evident that instead of the projecting elements apposite seats suited to be engaged with said coupling elements may be provided.
The coupling elements 21 are preferably defined on two bases, a front base 23 and a rear base 24, connected to each other preferably through a rigid metal strap 25. The two bases 23, 24 are connected to the metal strap 25 preferably through fixing rivets or nails, not illustrated in the figure. The two bases 23, 24 are therefore fixed integrally to each other.
A movement mechanism 26 is associated with the front base 23. The movement mechanism 26 comprises a lever 27 hinged to the first plate 2 with special tabs 28a, 28b, and a moving pin 29 connected to the lever 27 at one end and to the front base 23 at the other end.
In variant embodiments of the invention, the tabs may be created in a separate additional element conveniently connected to the first plate 2 or to the ski S. Again, in the preferred embodiment of the invention described and illustrated herein, the movement mechanism 26, and in particular the lever 27, are made in the front part of the connection system 1. However, in variant embodiments, the movement mechanism, and in particular the lever, may be provided in other points of the connection system, as shown for example in the embodiment of Figures from 8 to 1 1 , in which the movement mechanism acts on the rear part of the connection system 1. In the figures, the same numbers used for the first embodiment have been used, wherein the same number corresponds to the equivalent function described for the first embodiment.
Going back to the first embodiment, the rotation of the lever 27 causes the displacement of the moving pin 29 and the consequent displacement of the front base 23 and the rear base 24, through the rigid metal strap 25.
The displacement of the two bases 23, 24 with respect to the first plate 2 is allowed thanks to the presence of eyelets 30, 31 obtained in the respective bases 23, 24 and allowing the guided displacement of the bases 23, 24 with respect to the guide pins 32, 33 fixed to the first plate 2.
More particularly, with the coupling/releasing means 20 in their first rigid configuration, as shown in Figures 3 and 3A, the lever 27 is in the closed
position, the bases 23, 24 are in their completely backward position and the coupling elements 21 are engaged with the respective projecting elements 22 of the second plate 3.
In said configuration, therefore, the first and the second plate 2, 3 are fixed and stable with respect to each other and the binding A is in turn fixed and stable with respect to the ski S.
In this rigid configuration the unit can be used by the user for practising sports disciplines in which the boot must be in a fixed position with respect to the ski S, for example alpine skiing, free ride and free style on downhill routes.
If the user wishes to use the unit for a different sports discipline, or to modify its use in the current discipline, for example to pass to a movement on flat ground or uphill for free style and free ride, he/she will act on the lever 27 shifting it from the closed position to the open position, as shown in Figures 4 and 4A. The rotation of the lever 27 between the closed position and the open position causes the displacement of the bases 23, 24 to their completely forward position and the coupling elements 21 are released from the corresponding projecting elements 22 of the second plate 3.
In this condition the first and the second plate 2, 3 are no longer mutually fixed to each other but connected through the articulation means 10.
In a first operating condition shown in Figures 5 and 5A, the second plate 3 and therefore the binding A and the boot can perform a composite movement with respect to the first plate 2. In particular, the front part of the second plate 3 is raised with respect to the first plate 2 through the rotation of the connecting rods 1 1, 12 in the respective rotation pins 13, 14. At the same time, the rear end of the second plate 3 rests and slides on the first plate 2.
A projecting guide element 40 is preferably associated with the first plate 2 in order to guide the sliding movement of the first plate 2, said projecting guide element 40 being suited to be accommodated in a matching seat 42, visible in Figure 7, created in the second plate 3.
In variant embodiments of the invention said guide element may, however, be absent.
It is evident how said composite movement of the second plate 3 with respect to the first plate 2 comprises at least one rotation of the second plate 3 with respect to the first plate 2.
In particular, the second plate 3 rotates with respect to the first plate 2 around a
rotation axis that is parallel to the secondary axis Y.
Furthermore, said composite movement comprises also a translation of the second plate 3 with respect to the first plate 2.
In particular, the second plate 3 translates with respect to the first plate 2 along an axis that is parallel to the main axis X.
Finally, the second plate 3 is arranged at a certain angle D with respect to the first plate 2, as shown in Figure 5A.
Said operating condition substantially corresponds to the position in which the foot is forward while walking.
For this purpose, the connection system 1, and in particular the articulation means 10, are properly sized in order to allow said angle D to reach such values that the user never assumes positions that are inappropriate for walking. Preferably, the maximum amplitude of said angle D is maintained at values that are lower than or equal to 20°.
It should be noticed that said composite movement substantially depends on the selected length of the connecting rods 11, 12 and on the mutual position of the same with the corresponding articulation pins 13, 14 with respect to the first and the second plate 2, 3.
More particularly, as can be observed for example in the view shown in Figure 2, the area where the two connecting rods 1 1, 12 are jointed to the first plate 2, that is, the first articulation pin 13, is in a backward position with respect to the area where the two connecting rods 11, 12 are jointed to the second plate 3, that is, the second articulation pin 14.
In addition to the first operating condition described above and illustrated in Figures 5 and 5A, the first and the second plate 2, 3 can be arranged in further operating conditions, for example those shown in Figures 6 and 7. In these operating conditions, the user can freely lift his/her heel from the ski S.
The second plate 3 is therefore arranged at a given angle F with respect to the first plate 2, as shown in Figures 5A and 7A corresponding to two specific values of said angle F.
This operating condition substantially corresponds to the position in which the foot is moved backward when walking.
For this purpose, the connection system 1, and in particular the articulation means 10, are properly sized so as to allow said angle F to reach such values that the user never assumes positions that are inappropriate for walking. Preferably,
the maximum amplitute of said angle F is maintained at values that are lower than 90°.
In these operating conditions, and obviously in any one of the intermediate operating positions, the second plate 3 and thus the binding A and the boot can perform a composite movement with respect to the first plate 2. In particular, the rear part of the second plate 3 is lifted with respect to the first plate 2 through the rotation of the connecting rods 1 1, 12 in the respective articulation pins 13, 14. At the same time, the front end of the second plate 3 rests and slides on the first plate 2.
In order to favour said sliding movement, the front end of the second plate 3 is preferably provided with rolling means 41, preferably comprising a rolling needle.
Advantageously, said rolling needle 41 favours the mutual sliding movement of the two plates 2, 3 with the least possible friction.
Also in this case it is evident how the composite movement of the second plate 3 with respect to the first plate 2 comprises at least one rotation of the second plate 3 with respect to the first plate 2. In particular, the second plate 3 rotates with respect to the first plate 2 around a rotation axis that is parallel to the secondary axis Y.
Furthermore, said composite movement comprises also a translation of the second plate 3 with respect to the first plate 2. In particular, the second plate 3 translates with respect to the first plate 2 along an axis that is parallel to the main axis X.
In variant embodiments of the invention, the rolling means may be made in a different manner. For example, said rolling means may be constituted by rolling balls. Furthermore, said rolling means may indifferently belong to said first plate 2 or to said second plate 3 or even to both of them. Said rolling means are preferably arranged at the level of the contact and mutual rubbing area between the plates.
In further construction variants, the rolling means may be constituted by a shaped surface of the first plate, for example a cylindrical portion made in a single piece together with the first plate.
However, in variant embodiments of the invention, said rolling means may be absent, and the plates may simply be subjected to a mutual rubbing action.
The above clearly shows that the connection device that is the subject of the
invention makes it possible to achieve the set objects.
In particular, the connection device that is the subject of the invention makes it possible to easily pass from a rigid configuration, in which it is possible to practise a specific discipline with the boot fixed to the ski, to a configuration in which the foot can have at least one degree of freedom with respect to the ski. Advantageously, the user can use a single piece of equipment provided with the connection system of the invention in order to be able to practise different sports disciplines.
This leads to a reduction in the costs for the purchase of the equipment required for practising several disciplines.
Again, the possibility to use a single piece of equipment makes it possible to reduce storage spaces to a minimum.
The same advantages can be of benefit also to equipment rental companies that can keep a single type of equipment to offer to skiers for the different skiing disciplines. It has thus been shown that the present invention makes it possible to achieve the set objects. In particular, it makes it possible to provide a connection system for a ski binding that allows the user to practise several disciplines at limited costs.
