Abstract
A boot adapted for the practice of a sporting activity using a gliding or rolling apparatus, in which the heel of the boot is free during movement of the foot, the front end of the boot being provided with an element for fastening to the apparatus. The boot includes a base and an adaptation structure having a first portion to be fixed in a front zone of the base, and a second portion to be fixed in a rear zone of the base, each of which can be removably fixed.
Description
- This application is based upon French Patent Application No. 12/03259 and French Patent Application No. 12/03261, both filed Nov. 30, 2012, the disclosures of which are hereby incorporated by reference thereto in their entireties, and the priorities of which are claimed under 35 U.S.C. §119.
- 1. Field of the Invention
- The invention relates to an article of footwear, such as a boot, adapted to be reversibly retained or fixed to a sports apparatus, and relates more particularly to a boot intended for winter sports.
- Such article of footwear can be used in fields such as cross-country skiing, telemark skiing, snowshoeing, and the like.
- 2. Background Information
- A boot from the aforementioned family includes an outer sole assembly, an upper, and a fastening element; the latter being adapted to cooperate with a locking mechanism, itself adapted to be affixed to the apparatus. The fastening element and the locking mechanism form a fastening assembly that is often provided to retain the boot reversibly on the apparatus.
- For example, in cross-country skiing, each locking mechanism is typically capable of retaining or releasing a boot, thereby enabling the user to selectively operate the skis, or to walk.
-
FIG. 1 shows a known assembly comprising aboot 1, aski 2, and adevice 3 for retaining the boot on the ski. - The
retaining device 3 comprises abase 4 carrying areversible locking mechanism 5, anelastic return mechanism 6, and a longitudinal guidingrib 7. For example, it is possible to affix thelocking mechanism 5, thereturn mechanism 6 and the guidingrib 7 to thebase 4, so that theretaining device 3 is coherent, i.e., the individual components are integrated into a single device. As a matter of background, further information relating to exemplary devices of this type, including the components thereof, is disclosed in U.S. Pat. No. 6,017,050 and U.S. Pat. No. 7,644,947, the disclosures of which are hereby incorporated by reference thereto in their entireties. - The
boot 1 comprises an outersole assembly 12 and an upper 13. - The
boot 1 further comprises afastening element 25 adapted to cooperate with theretaining device 3, the retaining device itself adapted to be affixed to theski 2. Thefastening element 25 cooperates with thelocking mechanism 5 and theelastic return mechanism 6. - The
sole assembly 12, shown in more detail in a bottom view inFIG. 2 , also extends height-wise, or depth-wise, between anouter surface 18 and a connectingsurface 19. Theouter surface 18 is adapted to be turned toward the ground, theretaining device 3, or theski 2. - The connecting
surface 19 is used to affix thesole assembly 12 to the remainder of the boot by gluing. - The
fastening element 25 is connected to the outersole assembly 12, so that it can selectively be affixed thereto, or separated therefrom. - As explained in the document FR 2968898 and in family member US 2012/0151801, the
fastening element 25, and the rods orpins sole assembly 12. - A boot of this type, and in general, known boots, have a limitation that is their inability to adapt to various types of equipment. In particular, there are two large families in the field of cross-country skis, namely the NNN® (“New Nordic Norm”) family and the SNS® (“Salomon Nordic System”) family. A boot provided with structures for connection to skis from one the two aforementioned types cannot be used for the other type, thus requiring from the user to have two pairs of boots if he/she wishes to freely use both types ski.
- Another drawback is that of the longitudinal flexibility of the boot along a transverse axis thereof. This flexibility is inherent in the manufacture of the boot and cannot be adjusted as needed by the user.
-
- Still another drawback lies in the wear on the portions that are in contact with the ground, the ski, or the snowshoe. The wear on these portions requires replacement of the entire boot.
- In view of the preceding, the present application discloses a boot adapted for the practice of a sporting activity using a gliding or rolling apparatus, for example skis or snowshoes, in which the heel of the boot is free during movement of the foot, the front end of the boot being provided with an element for fastening to the device, this boot comprising a base.
- The boot further comprises adaptation structure, comprising a first portion to be fixed in a front zone of the base of the boot, in relation to a direction of extension of the foot, i.e., the length of the foot, and second portion to be fixed in a rear zone of the base of the boot, in relation to such direction of extension of the foot, each portion being capable of being removably fixed in relation to the base. This is to adapt the boot, for example, to a first type of interface of contact with the apparatus, or to a second type of interface of contact with the apparatus, different from the first type of contact interface, or to any other type of interface.
- The rolling or gliding apparatus may be ski, as indicated above, but more generally an apparatus for moving on snow or ice, or on a natural surface and/or a synthetic surface, such as an asphalt-covered surface.
- Depending upon the wear on the constituent portions of the adaptation structure, and/or the technical constraints imposed on the user, such as the presence of a specific type of retaining device and/or standard, or a specific type of ski or apparatus, the user is able to adapt these structures easily, without it being necessary to change the boot.
- The two front and rear portions may be affixed to one another, for example connected by a base/blade, which may or may not be flexible, in order not to interfere with the bending of the boot.
- The first type of contact interface may be with a single longitudinal rib, the first portion and/or second portion of the adaptation structure each comprising a longitudinal groove adapted to receive at least a portion of the single longitudinal rib.
- The second type of contact interface can be with at least two longitudinal ribs, or even n longitudinal ribs, n being greater than two, the first portion and/or second portion of the adaptation structure each comprising at least two, or n, longitudinal grooves, each groove being adapted to receive at least a portion of one of the two, or of n, longitudinal ribs.
- According to other examples, a contact interface comprises at least one transverse rib and/or at least one stud, the first portion or second portion of the adaptation means comprising at least one transverse groove or at least one opening, each groove or each opening being adapted to receive a transverse rib or a stud.
- The base of the boot may have flexibility along a direction of extension of the foot, i.e., along the length of the foot, when positioned in the boot.
- The base may comprise a flexion blade, such flexion blade having flexibility along a direction of extension of the foot, and a construction that fastens the adaptation structure against the blade.
- The base, or flexion blade, may be substantially flat, or it may also comprise walls, and possibly a stiffener-forming portion for supporting the rear portion of the upper or the liner of a boot. In a non-limiting fashion, the stiffener is an outer subdivision of the boot. Alternatively, however, the stiffener could be covered with another element and, as a result, the stiffener would be set back in relation to the outside of the boot.
- Removable structure may further be provided to vary the flexibility of the base or flexion blade, such structure comprising, for example, one or more inserts and/or one or more rods and/or one or more plates or blades to be inserted into, or against, such base.
- Structure may be provided for fixing the adaptation structure in relation to the base, for example screws, slides, or snap-fasteners, in one position or a plurality of discrete or continuous positions.
- In a particular embodiment, at least one contact interface comprises a surface of the apparatus itself, the first portion and/or second portion of the adaptation structure comprising at least one longitudinal groove. Each groove may have a width at least equal to the width of the apparatus.
- More generally speaking, the first portion and/or second portion of the adaptation structure has a transverse cross-section whose profile is complementary to a profile of a transverse cross-section of a retaining device, of an interface element between the boot and the apparatus, or of the apparatus itself. In any case, the idea is to adapt the boot to the apparatus.
- The invention also relates to a boot, adapted for the practice of a sporting activity using a gliding or rolling apparatus, in which the heel of the boot is free during movement of the foot, the front end of the boot being provided with an element for fastening to the apparatus, the boot comprising a base, and adaptation structure, to be removably fixed in a front zone of the base of the boot, in relation to a direction of the extension of the foot, in order to adapt the boot to a first type of contact interface of the apparatus, or to a second type of contact interface of the apparatus, different from the first type of contact interface, the rear portion of the base being adapted to rest directly or indirectly on a surface of contact interface of the apparatus. This means that the base, depending upon the configuration, can rest directly on the apparatus or, alternatively, on an interface plate, on the base of a retaining device, or on both the plate and the base, if they are superimposed.
- The front portion and rear portion of the adaptation structure may have different heights.
- The front portion and/or rear portion of the adaptation structure may have a surface, adapted to come into contact with the base, forming a non-zero angle with the opposite surface, adapted to come into contact with, or to be turned toward, the apparatus. This assembly is obtained in at least one direction.
- In a boot as described above, or as described in one of the above alternative embodiments, the adaptation structure may comprise first removable structure for adapting the boot to the first type of contact interface of a ski, of a snowshoe, or of another apparatus, and second removable structure for adapting the boot to the second type of contact interface of a ski, of a snowshoe, or of another apparatus.
- A boot as described above may be of a shell-type, made of one, two, or three portions, receiving a liner or an upper mounted, for example with a removable front and/or rear end-piece, in relation to the base. It may also be a Strobel-mounted upper receiving a glued base, itself receiving the adaptation structure.
- In general, the contact interface of the apparatus may comprise a device for retaining or fastening the boot, adapted to cooperate with the front end thereof, or may be a surface of the apparatus itself.

However, the invention applies to other fields, such as ice skating or roller skating, for example. In the case of a ski, the latter can possibly be provided with rollers, such as the
rollers - In the following description, reference is made to a ski boot having a structure of various types. According to an example, this structure may be identical or similar to that already described with reference to
FIG. 1 , except for the portion located under the upper and turned toward the skis. - The structure of
FIG. 1 comprises aboot 1, aski 2, and adevice 3 for retaining the boot on the ski: -
- the
boot 1 comprises an outer sole assembly, orouter base 12, and an upper 13, these two elements being assembled for example with glue, rivets, or screws, or they can be at least partially integrated into the same element, which may be molded, for example, in a thermoplastic or composite material. The base 12 may include one, two, or more portions. Theboot 1 extends lengthwise, from a rear end, orheel 14, to a front end, ortip 15, and a widthwise, between alateral side 16 andmedial side 17. The base 12 also extends lengthwise, from theheel 14 to thetip 15, and widthwise, between thelateral side 16 andmedial side 17, - the upper 13 comprises a
lower portion 20, provided to surround the foot, and possibly atop portion 21, provided to surround the ankle and even extend above the ankle. The upper may comprise only the lower portion, - a
fastening element 25 is provided to cooperate with the retainingdevice 3, in particular thelocking mechanism 5, itself adapted to be affixed to theski 2, and possibly with anelastic return mechanism 6, - the retaining
device 3 comprises abase 4 carrying areversible locking mechanism 5, possibly anelastic return mechanism 6 and, in the example shown inFIG. 1 , alongitudinal guiding rib 7, thelocking mechanism 5, thepossible return mechanism 6 and the guidingrib 7 can be affixed to thebase 4.
- the
- The invention also applies to other types of boots, especially the types of boots shown in
FIGS. 14A-H , or to other types of bindings. - Thus, the boot of
FIG. 14A comprises a removablefront end piece 220 and acradle 214 which, in particular, serves as thebase 120 and the stiffener. The stiffener is an outer subdivision of the boot. In a non-limiting fashion, theend piece 220 has the appearance of a removable and/or adjustable shell, making it possible to adapt the boot to the size of the user. The user slips aliner 215 or a boot into this assembly, in which the user's foot is inserted. The end piece is fitted on the cradle, to which it can then be fixed, for example with rivets, screws, or glue. This end piece can be made of a plastic and/or composite material, and/or a flexible, textile or synthetic material. - In an alternative embodiment, according to
FIG. 14B , the outer stiffener is also removable: similar end piece, it is adapted to be fixed on a base or flexion blade 120 (as explained below), and it can be disassembled therefrom. The blade itself then constitutes most of the base. - The boot of
FIG. 14C is similar to that ofFIG. 14A , but has aperforated cradle 214. This reduces the mass of the boot, and therefore its mechanical inertia. - According to the embodiment shown in
FIG. 14D , the end-piece 220, thecradle 214, and the base 120 form a unitary, single-piece element. This has the advantage of simplicity. - In
FIG. 14E , the boot has no end-piece, but only abase 120 and a rear cradle 324, which form a unitary, single-piece element. This embodiment promotes reversible bending of the base 120 forward, and in the area of the metatarsus of a foot. - In
FIG. 14F , the boot does not have an end-piece, but includes thebase 120 and therear cradle 214, which are two separate elements assembled to one another by any suitable expedient. - In
FIG. 14G , the boot comprises abase 120, but does not include an end-piece or a cradle. The boot also includes a high upper 13, removably or permanently affixed to thebase 120 by any suitable expedient. The high upper is well-suited to the skating step technique of skiing, for which the user exerts lateral thrust with the legs. - In
FIG. 14H , alternatively, the upper of the boot is a low upper, which is suitable for the alternate step technique of skiing. - More typically, the boot or footwear element according to the invention comprises a base, which is not necessarily glued against an upper.
- In general, the base is adapted to receive, on one of its surfaces, either a boot, or structural elements of an upper, themselves adapted to receive a boot or a liner in which the user's foot is inserted.
- More particularly, the boot can be provided to include a base on which a mounted upper is attached. For example, this latter comprises an envelope for covering the foot and a lasting board adapted to close the envelope beneath the foot, to the exclusion of any conventional sole assembly. The mounted upper is affixed to the base by means of a glue, for example, or any other appropriate expedient, it being known that, in the prior art, in a very different approach, would have led to affixing the mounted upper to a sole assembly.
- According to the alternative embodiment of
FIG. 14B , the base comprises a longitudinal flexion blade, a removable cradle, and a removable end-piece. This means that the flexion blade, the cradle, and the end-piece are elements assembled to one another to form the base. In other words, these elements, in this case, do not form a unitary, single-piece element. - The base has another surface that is generally facing the ground or the apparatus (e.g., the ski) and has the function of interfacing with the adaptation structure described below.
-
Such adaptation structure FIGS. 3A and 3B . Here again, thebase 12 extends depth-wise, between anouter surface 18 and a connectingsurface 19. Theouter surface 18 is adapted to be turned toward the ground, the retainingdevice 3, or theski 2. - The connecting
surface 19 serves to affix the base 12 to the remainder of the boot, for example by gluing (but other methods of affixing or fixing are possible, as explained above). - According an embodiment, the adaptation structure comprises a
front fastening element 25 including a firstlongitudinal bar 31 and a secondlongitudinal bar 32, both provided to be supported on thebase 12. The base may also be designated by thereference numeral 120. Thefirst bar 31 extends longitudinally from afirst end 33 to asecond end 34, and thesecond bar 32 extends longitudinally from afirst end 35 to asecond end 36. For example, the first ends 33, 35 and second ends 34, 36 of the bars are provided to be transversely opposite one another, respectively. - Each
bar - Each of the bars is provided with at least one possibly through
opening screw 47 adapted to cooperate with a threaded opening 48 1, 48 2, 48 3, 48 4 of the base. Alternatively, a threaded insert can be provided in the base, but also a reverse embodiment, with an internal screw thread or a threaded insert in the front or rear adaptation structure, is within the scope of the invention. - Positioning
studs 43, 44, for example beneath eachbar corresponding openings - The two
longitudinal bars FIGS. 3C , 3D, in which the bars may then be connected to one another by aportion bars 31, 32 (in the case ofFIG. 3C ), or over the entirety of this length (in the case ofFIG. 3D ). The bars and the portion can form a unitary, single-piece element. -
FIGS. 3A , 3B also show aremovable heel 140 comprising a firstlongitudinal bar 310 and a secondlongitudinal bar 320, connected by a bridge made in the form of aflat zone 315, for example, set back in relation to the outer surface of the heel, in order to cooperate with the single rail of a ski or of the retaining device, for example of the SNS® type. This assembly is adapted to take support on theouter base 12. Thefirst bar 310 extends longitudinally from afirst end 330 to asecond end 340, and thesecond bar 320 extends longitudinally from afirst end 350 to asecond end 360. For example, the first ends 330, 350 and second ends 340, 360 of these bars are provided to be transversely opposite one another, respectively. A heel is shown here, in which the twolongitudinal bars flat zone 315. However, this zone may be further reduced in relation to the length of the heel. - Each
bar - In general, the outer surface of these bars, adapted to come into contact with the apparatus or with means forming one or more contact interfaces, can be planar and homogeneous, or can comprise notches, such as illustrated in
FIG. 5 or 7B, for example. - Structure is provided for positioning the heel fixedly, but removably, in relation to the base.
- For example, as shown in
FIG. 3A , each of the bars is provided with at least one possibly through opening 470 1, 470 2, 470 3, 470 4, for example two openings, each of which can be threaded to receive a screw 470 adapted to cooperate with a threaded opening 480 1, 480 2, 48 3, 480 4 of the base. Alternatively, a threaded insert can be provided in the base, but also a reverse embodiment, with an internal screw thread or a threaded insert in the front or rear adaptation structure. - Positioning
studs bar corresponding openings - The example shown in
FIGS. 3A and 3B comprises two connector rods or pins 26, 27 in the front portion of the adaptation structure. However, in this example, as in the other examples described below, a single connector rod or pin can also be provided. - Fastening structure of a different form can also be provided, which is not necessarily a pivot-type connection with the retaining device, but may be a non-rotatable mechanical connection.
- In an alternative embodiment, shown in
FIG. 4 (in which the removable elements are the same as those ofFIGS. 3A and 3B ), the openings of the base 12 can be doubled to make it possible to adapt the position of the heel and/or the front portion. - Thus,
FIG. 4 shows additional openings 48′1, 48′2, 48′3, 48′4, each shown slightly behind one of the openings 48 1, 48 2, 48 3, 48 4. The same goes for theopenings studs 43, 44. The set of additional openings defines a second possible position of the screws and studs of theremovable element 25, which can thus be moved forward or backward on the base, as appropriate. A number of positions greater than two, for example three, may be provided. A discrete longitudinal adjustment with two, three, or any number of longitudinal positions, may be carried out. - Similarly,
FIG. 4 shows additional openings 480′1, 480′2, 480′3, 480′4, each shown slightly behind one of the openings 480 1, 480 2, 480 3, 480 4. The same goes for theopenings studs - Another embodiment of the structure for fastening the removable portions is shown in
FIG. 5 . It is provided for a continuous adjustment, the displacement of the front and rear elements being longitudinal, which increases the possibilities of adjustment of the position of the front and rear elements. For example, at least twoparallel rails front element 25, which may be formed beneath the firstlongitudinal bar 31 and the secondlongitudinal bar 32, on the side adapted to be turned towards the base. - In a plane perpendicular to the surface of the base, and perpendicular to the direction of elongation of the base, each rail has a substantially inverted “L” configuration, comprising a body perpendicular to the base, and a horizontal portion enabling the
element 25 to slide on the rail, on one hand, and to retain the latter with respect to the base, on the other hand. In the illustrated embodiment, the horizontal bar of the inverted “L” is directed outward of the boot. - Each rail itself may be made of two
portions surface 121, set back in relation to the outer surface of the rails turned toward the side opposite the upper. This zone orsurface 121 can be merged with theouter surface 18 of the base (which has the advantage of a lesser effect on the flexibility of the base). One or more screw-threadedopenings surface 121. Alternatively, a variation may be provided, in which the hole is a through opening, such as a slot. Each of thelongitudinal bars adjustment slot screw 105 may be inserted to be screwed into one of theopenings rails - The
rails slots longitudinal elements rear portions front portions longitudinal elements element 25, the end of the slots, located on therear end portions longitudinal elements rail elements element 25 is pulled in a rearward direction of the boot. - The same applies to the
heel 140, the base comprising at least twoparallel rails longitudinal bar 310, or beneath the secondlongitudinal bar 320, on the side adapted to be turned toward the base, and, in a particular embodiment, in the extension of the inner surface of thezone 315 for connecting the two bars. - Each rail may be made of two longitudinally
elongated portion surface 122, set back in relation to the outer surface of the rails turned toward the side opposite the upper. This zone orsurface 122, for example planar, can be merged with theouter surface 18 of the base. In this zone, for example planar, one or more screw-threadedopenings longitudinal bars adjustment slot screw 1050 can be inserted in order to be screwed into one of theopenings rails - The
rails slots rail elements - The movable elements, that is to say, the front and rear adaptation structures, are retained against the base, for example by screws or snap -fasteners.
- In a particular embodiment, the surfaces in contact with one another, that is to say, the
surface 18 and the surfaces of thelongitudinal elements - In a plane perpendicular to the direction of elongation of the base, each rail has a substantially inverted “L” configuration, as has been described above, and with the same advantages.
- Another embodiment of the structure for fixing the removable portions is shown in
FIG. 6 , provided for adjustment in two dimensions in the plane of the base. Such an adjustment is carried out continuously, in a particular embodiment, but alternatively also depending upon a succession of discrete positions. The displacement of the front and rear elements then occurs along the longitudinal direction of the boot and/or along a direction perpendicular to this longitudinal direction, thereby increasing the possibilities of adjustment of the position of the front and rear elements. For example, twoparallel slots parallel slots Slots 83, 88 (in the front portion 25) and 830, 880 (in the heel-forming portion 140), respectively, are provided in each of the tworemovable portions - In the embodiments of
FIGS. 5 and 6 , one or more positional reference marks may be provided to enable a user to laterally and/or transversely identify a specific setting, for example a suitable setting for a given type of boot. Thus, a lateral adjustment scale RE is shown inFIG. 5 , provided in or on thesurface 18, parallel to the direction of insertion of the longitudinal bars. A transverse adjustment scale Et is shown inFIG. 6 , provided in or on thesurface 18, perpendicular to the direction of insertion of the longitudinal bars. One or more positional reference marks may be present to locate the position of the front portion of the adaptation element (as shown inFIGS. 5 and 6 ) and/or the rear portion of the adaptation element. - The various exemplary embodiments given described above with reference to
FIGS. 3A-6 are intended for use with a particular type of ski, from the SNS® family, with a single-piece rail 7 (or guiding rib). - To enable the same boot to be used with the other family, the previously described
elements - Indeed, a removable heel and a removable fastening element can also be structured to cooperate with the two ribs of a retaining device from the NNN® type. These two ribs form longitudinal guiding elements, at least in the portion with which the heel comes into contact.
- A
heel 140 of this type is shown inFIG. 7A . It comprises a firstlongitudinal bar 310, a secondlongitudinal bar 320, and a thirdlongitudinal bar 333, arranged between the first longitudinal bar and the second longitudinal bar, and separated therefrom, by a firstlongitudinal groove 131 and a secondlongitudinal groove 132, respectively. These grooves are provided to cooperate with the rails of a retaining device from the NNN® family. - Structures are provided for positioning the heel fixedly, but removably, in relation to the base. They may be of the same type as that described above with reference to
FIG. 3A , in which one or more possibly through holes 470 1, 470 2, 470 3, 470 4, possibly threaded, made, for example, in thelongitudinal bars positioning studs corresponding openings FIGS. 4 , 5, and 6. - The corresponding
front portion 25 is shown inFIG. 7B . A single connector rod orpin 26 is positioned in the front position. The front portion comprises a firstlongitudinal bar 31, a secondlongitudinal bar 32, and a thirdlongitudinal bar 37 arranged between the first longitudinal bar and the second longitudinal bar, and separated therefrom by a firstlongitudinal groove 31′ and a secondlongitudinal groove 32′, respectively. These grooves are provided to cooperate with the rails of a retaining device from the NNN® type. Structures are provided for positioning the front portion fixedly but removably in relation to the base. They may be of the same type as that described above with reference toFIG. 3A , or one ofFIGS. 4 , 5, and 6. - Each of
FIGS. 8A and 8B shows a rear view of the boot, on which theremovable heel 140 is mounted. Clearly shown is the structural difference that enables each of these heels to be adapted to a particular type of ski.FIGS. 8C and 8D are front views which correspond toFIGS. 8A and 8B , respectively, showing the elements already described above. - Elements of the type shown and described above with reference to
FIGS. 7A-7B , adapted to the NNN® family, can be adapted to the various binding structures that have been described above with reference toFIGS. 3A-6 , thereby possibly providing them with discrete (FIG. 4 ) or continuous (FIGS. 5 and 6 ) adjustability. - The above embodiments are provided for direct attachment to the base.
- According to another embodiment, a
base 200 receives a liner and/or an upper and/or structural elements of a boot upper, as shown inFIG. 9 . Thereference numeral 210 designates a collar provided with astrap 211 for retaining the boot. This strap can be opened or closed using means such as hook and loop surfaces, for example. On the side of the heel, thebase 200 is provided with two substantially vertical walls 201 (lateral wall) and 203 (medial wall), which make it possible to retain the rear portion of the upper and, more particularly, to block possible twisting of the foot. These two vertical walls may be separate or, conversely, extended at the rear by a portion (rear bridge) which joins the rear portions of thewalls walls base 200, which substantially corresponds to the position of the metatarsals. When the boot or the liner is inserted into this base, twoopenings collar 210 to retain the assembly or to help to retain the assembly. Astrap 211′ for retaining the upper on the base may also be present in the front portion of the base; this strap can be opened or closed using means such as hook and loop surfaces, for example. The upper can also be retained in, or on, the base by glue, screws, or rivets. - The front and rear removable portions, described above, can then be fixed to the outer surface of the
base 200, with means identical or similar to those mentioned above, in particular screws, and possibly positioning studs. The blade is itself provided with corresponding openings, some of which may be threaded for cooperation with the corresponding screws. -
FIGS. 10A-10B show the various structures for retaining theelements base 200 of which the lower orouter surface 18 facing the apparatus or the ground becomes the base 12 described above (the latter thus forming the main portion of the base). More detailed explanations have already been given above with reference toFIGS. 4-6 . Here again,elements - In an alternative embodiment, the base does not include
walls FIGS. 3A-6 , replacing the material of the base described above in these drawing figures with the material of the flexion blade. The front and rear portions of the adaptation structure, described above with reference to theseFIGS. 3A-6 , are then adapted to be fixed against this blade. - Two removable portions forming two separate elements have been described above.
- In an alternative embodiment, however, a single element can be made, adapted to be applied against the base or the flexion blade; such an element is shown in
FIGS. 11A and 11B . These figures show that the structures for retaining the twoportions base 12, or thebase 200, are the same as those described above with reference toFIG. 3A . The twoportions flexion blade 120, which has flexibility to accompany the movement of the user. This assembly is compatible with a mode of binding to one position on the base, as inFIG. 3A , or to two or more discrete positions, as inFIG. 4 . A method of binding with continuous positional adjustment, although not shown, can also be provided. The base is made, for example, of a metallic and/or composite and/or plastic material and/or a material comprising plant fibers. - As shown in
FIG. 12 , an assembly can also be made, comprising twoelements FIG. 5 , also connected by abase 120, the assembly being capable of being used in cooperation with a base of the type shown inFIG. 5 . - Similarly, the two
portions FIG. 6 can be connected by a base in order to form a unitary, single-piece element. - In the various alternative embodiment which have just been described, the connecting
element 120 has a forward extension, which is limited in order not to impede the connector rods or pins 26, 27 adapted to cooperate with the retaining device 3 (seeFIG. 1 ). - Each of these different single-piece alternatives can be fixed to a
base 12, as described above. - The base of
FIG. 9 , like the base 12, has a certain longitudinal flexibility along a transverse axis of the boot. It can be flexed to accompany movements of the foot. However, it may be necessary to adapt this flexibility. This can be done by replacing the first base with a second base with a different flexibility (more rigid or more flexible than the first). However, a base with adaptable/adjustable flexibility can also be provided. - To this end, the invention provides reinforcement structure such as inserts in the form of rods, for example, which can be inserted into openings extending longitudinally or angularly offset with respect to the longitudinal direction, in the base, as shown in
FIG. 13A , which shows abase 200, andopenings reinforcements openings opening 224, on the front or rear surface, makes it possible to receive a reinforcingelement 225 having, in this case, the form of a rectangular plate, as shown inFIG. 13B . The plate, which may have any shape, may also be arranged either above or below thebase 200. In another variation, a reinforcing member may be a plate or ablade 227, possibly perforated, as shown inFIG. 13C , and adapted to be pressed against the upper or lower surface of the base, such as in the zone on which the front portion (as inFIG. 13C ) or the rear portion of the adaptation structure is to be fixed, or between these two zones, as designated by thereference numeral 227′ inFIG. 13C . This reinforcing structure can be adapted to such a blade, whether the latter is provided in combination withremovable elements - The connecting structure connecting the
fastening element 25 to thebase 12, and the removable heel, both enable adaptation of the boot to any type of ski. - In all of the embodiments that have been described, the front and rear elements to be fixed to the outer surface of the base are compatible with the NNN® family or the SNS® family.
- However, the invention also relates to other retaining devices or other types of equipment.
- For example, there can be n parallel ribs (n>2), instead of the two ribs of the device with which the elements of
FIGS. 7A and 7B cooperate. - By way of another example, as shown in
FIG. 15A , the front interface zone of the retaining device may be provided with one or moretransverse ribs transverse ribs FIG. 15B , which shows that each of them comprises, in its lower portion adapted to be in contact with the retaining device, one ormore recesses 70′, 71′, 72′, 73′ whose shape corresponds to the front or rear ribs, and which make it possible to at least partially receive the front or rear ribs. - Another example is illustrated in
FIG. 16A , in which the front interface zone of the retaining device is provided with one ormore studs more studs FIGS. 16B and 16C , which show that each of them comprises, in its lower portion adapted to be in contact with the retaining device, one ormore openings 74′, 75′, 76′, 77′ whose shape corresponds to the front and rear studs, and which make it possible to at least partially receive these front or rear studs. - The embodiments described above can be combined. For example, the ski may comprise:
-
- at least one
transverse rib - one or
more studs
- at least one
- Or the ski may comprise:
-
- one or more longitudinal ribs, as shown in
FIG. 1 , in the front interface zone adapted to receive the front portion of the boot; and - at least one transverse rib, oriented perpendicular to the direction of extension of the ski, in the rear interface zone adapted to receive the rear portion of the boot.
- one or more longitudinal ribs, as shown in
- In other words, the ski comprises:
-
- a front interface zone adapted to receive the front portion of the boot, this front interface zone being of a first type, comprising one or more elements in elevation in relation to the planar surface of the ski, having one or more first geometric shapes; and
- a rear interface zone adapted to receive the rear portion of the boot, this rear interface zone being of a second type, comprising one or more elements in elevation in relation to the planar surface of the ski, having one or more second geometric shapes, at least one of which is different from the one or more first geometric shapes.
- Another embodiment is illustrated in
FIG. 17A , in which the ski does not have any rib or stud in the zone adapted to receive a boot or a base. In this case, however, the boot is wide enough to comprise adaptation structure, in the form of a slot orgroove FIGS. 17B to 17D . Thegroove - When the boot is positioned on the ski, it extends beyond each side thereof. Alternatively,
front 25 and rear 140 adaptation structure comprises, in the lower portion adapted to be in contact with the ski, an opening orgroove groove FIGS. 17B-17D against the base. Thus, the openings 47 1-47 4 and 470 1-470 4 make it possible to insert screws, for example, for retention against the base. - In all of the cases described above, the front and rear elements to be fixed to the outer surface of the base have substantially identical heights.
- However, as shown in
FIGS. 18A and 18B , different heights can also be provided for these elements: -
- the front element having a first height h1 measured between the two main surfaces of this element (the surface facing the base and that facing the ski or the snowshoe);
- the rear element having a second height h2, measured in the same manner.
- In most of the cases described above, the front and rear elements to be fixed on the outer surface of the base are planar surfaces, substantially parallel to one another. However, non-parallel surfaces can be provided, along at least one direction, in order to adapt the positioning on a device, such as a ski or snowshoe, to a particular morphology of a user (e.g., to compensate for orientations of the knee) and/or to enable amplified or increased acceleration effects.
- Thus,
FIG. 19A shows an example of a front element whose outer surface is inclined by an angle value α1, in relation to the inner surface (adapted to come into contact with the base), from the lateral side (facing outward of the user during use) to the medial side (facing inward of the legs of the user during use). -
FIG. 19B shows a rear element also having such a lateral inclination α1. -
FIG. 19C shows an example of a front element, the outer surface of which is inclined in relation to the inner surface (adapted to come into contact with the base), from the rear to the front. Such element enables a forward inclination of the user. However a reverse arrangement can be provided, with an element that enables a rearward inclination of the user. - A front or rear element may have an outer surface combining the two types of inclinations described above, and is inclined:
-
- in relation to the inner surface (adapted to come into contact with the base), from the lateral side (facing outward of the user during use) to the medial side (facing inside of the legs of the user during use); and
- in relation to the inner surface (adapted to come into contact with the base), from the rear to the front or vice versa. Such an element enables forward or rearward inclination of the user.
- It is to be understood that a user can choose the type of inclination most suitable for him/her, for physiological reasons and/or performance, and can adjust the element to the base in the mariner explained above.
- In all of the cases described above, the adaptation structures comprise a front element and a rear element to be fixed to the outer surface of the base.
- In certain cases, the adaptation structure may comprise a portion to be fixed to the front of the base (reference will then once again be made to a “front” portion), but it is not necessary to fix a rear portion, or heel, to the rear of the base; this is the case in which the fastening element of the front portion is sufficiently rigid to enable to latter to carry out, by itself, a function of guiding the apparatus.
- This embodiment is shown in
FIGS. 20A-20B . In these drawing figures the reference numerals designate elements that are identical or similar to those described above with reference toFIGS. 3A-3B . No elements are fixed to the rear portion of the base. The assembly cooperates, for example, with a ski illustrated inFIG. 20C , comprising aretaining device 3 and asupport surface 700 for the rear portion of the base, or the heel. - In all of the cases described above, the fastening means comprise one or two wires. However, as has been shown, other types of fastening means may be implemented, for example those of
FIGS. 21A and 21B . In these drawing figures, afastening device 60 comprises afastening element 61 affixed by any means, for example to the boot, as well as alocking mechanism 62 also affixed by any means, for example to the apparatus. Thefastening element 61 comprises afirst finger 63 adapted to fit into anotch 64 of themechanism 62. Thefastening element 61 also comprises asecond finger 65 provided to cooperate with ahook 66 of themechanism 62, the hook being movable against the action of an elastic means, not shown. Pressing with the boot on the ski causes the locking, whereas actuation of arelease button 67, against the action of elastic means, releases the boot. - In any event, the positioning of the front portion or rear portion, respectively, of the adaptation means has a longitudinal extension that can go up to 30%, 35%, or 40% of the length of the base, measured from the rear or front end of the base, respectively.
- The teaching described above in connection with a ski can be transposed to snowshoes.
- In any case, the invention is made from materials and according to technical implementation techniques known to one with ordinary skill in the art. The front and rear portions of the adaptation means are made with a reduced number (2-4) of molds, compared to the number (8-15) of molds used to produce all the sizes of the currently known boot soles. From an economic point of view, the advantage is considerable because an investment ranging between about 10 and 40 K is required to make each mold.
- Naturally, the invention is not limited to the embodiments described above, and includes all technical equivalents that fall within the scope of the claims that follow.
- In particular, in certain cases, the
first portion 25, or fastening element, to be fixed in a front zone of the base of the boot and thesecond portion 140, or fastening element, are provided not to be affixed to one another, or dissociated from one another, when neither one is fixed to the base of the boot. - Alternatively, in other cases, the
first portion 25 to be fixed in a front zone of the base of the boot and the secondrear portion 140 are provided to be affixed to one another, when neither one is fixed to the boot. - According to these alternatives, the
first portion 25 andsecond portion 140 are connected by a flexible blade. - At least because the invention is disclosed herein in a manner that enables one to make and use it, by virtue of the disclosure of particular exemplary embodiments of the invention, the invention can be practiced in the absence of any additional element or additional structure that is not specifically disclosed herein.
