Definitions

  • the invention relates to a binding device for attaching a boot to a sliding board, in particular to a snow sliding board, in particular to a snowboard.
  • the invention also relates to a boot intended to be attached to a sliding board.
  • the invention relates to a binding system for snowboarding comprising such a binding device and such a boot.
  • Snowboarding, or snow surfing consists of descending snowy slopes using a board to which the user's two shoes are attached.
  • a binding device is generally used comprising a support attached to the board and several flexible straps attached to the support at their ends and passing over the shoe.
  • the support generally made of plastic, at least partially envelops the sole, the back and the sides of the shoe.
  • the binding generally comprises two straps, one of which passes over the instep and the other passes over the front of the shoe. These straps are used to firmly hold the shoe against the bottom of the support.
  • Each strap is made up of two parts capable of cooperating together via a tightening means in order to obtain good support for the foot.
  • the user To attach a shoe to the board, the user must therefore generally position his foot at the bottom of the binding support and then successively tighten the binding straps. This operation is tedious and often requires the user to sit in the snow to put on the snowboard. However, this operation must be repeated many times during a day of snowboarding since using the ski lifts generally requires that at least one of the two feet be unshod. The tightening obtained after each manipulation may be different. The user must therefore get used to practicing snowboarding with a comfort that may be different between each tightening and loosening operation.
  • the existing straps are made of soft plastic and can break, which can be particularly dangerous when the user goes down a ski slope at full speed.
  • bindings commonly called “step-in", capable of cooperating with a binding device integrated under the sole of the boot. These bindings provide faster putting on when the sole is not clogged with snow. However, when snow or ice clings to the binding device under the sole, putting on the boot can become more difficult or even impossible. It is therefore often necessary to carefully clean the sole in order to successfully attach the boot to the board.
  • a binding system provides foot support via the sole and not via the top of the foot or the instep as in conventional binding systems and users do not appreciate the sensations created by this type of connection. Indeed, the transmission of forces from the foot to the board is less precise and the sensations perceived by the user are degraded. The comfort provided by such bindings can also be impaired by pressure points due to the binding mechanism, arranged under the user's foot.
  • the document WO2012/058451 A1 discloses a fixation according to the preamble of claim 1.
  • the aim of the invention is to provide a fastening system for attaching a shoe to a sliding board, overcoming the above drawbacks and improving the fastening systems known from the prior art.
  • a first object of the invention is a practical fixing device to use and allowing a shoe to be easily and quickly fixed or released from a sliding board.
  • a second object of the invention is a fixing device allowing optimal transmission of impulses from a user to a sliding board to control its movement.
  • a third object of the invention is a comfortable fixing device for the user's foot.
  • a fourth object of the invention is an automatic fastening device usable even when snow is likely to accumulate under the sole of a shoe.
  • the lever may include a gripping member for moving the lever from its first position to its second position in the tightening direction.
  • the lever may be arranged along a lateral side of the base, and the lever may be adapted to cooperate with a laterally extending retaining member of the shoe.
  • the lever may include a first bearing surface capable of vertically retaining the lateral retaining element and the first bearing surface may be cam-shaped.
  • the first bearing surface may comprise a first portion intended to bear against the retaining element when the lever is in its first position, the first bearing surface comprising a second portion intended to bear against the retaining element when the lever is in its second position, the second portion being distinct from the first portion.
  • the lever may be movable in rotation about an axis of rotation, the axis of rotation extending parallel to a transverse axis of the fixing device, the distance separating said first portion from the axis of rotation being strictly greater than the distance separating said second portion from the axis of rotation.
  • the lever may comprise an opening, an edge of the opening forming said first bearing surface.
  • the first support surface of the lever may comprise an arc shape eccentric with respect to the axis of rotation.
  • the first lever bearing surface may comprise a row of notches, each notch defining a stable clamping position of the lever.
  • the base may include a lateral side provided with a guide groove oriented and open towards the front and towards the top.
  • the lever may comprise a second bearing surface forming a shoeing ramp, the second bearing surface being intended to cooperate with the retaining element to move the lever from an initial position to a third retracted position.
  • the fixing device may comprise a return means, the return means exerting a force on the lever tending to move it from its third retracted position to its initial position.
  • the lever may include a release handle, a downward force on the release handle tending to move the lever to its third retracted position.
  • the base may comprise a stop means positioned at the front of the base, the stop means being capable of cooperating with a mating element of the shoe.
  • the fastening device may comprise a first lever movable relative to the base and a second lever movable relative to the base, the first lever being able to cooperate with a first retaining element connected to a shoe, the second lever being able to cooperate with a second retaining element connected to a shoe, the first lever being movable between a first holding position and a second tightening position, the second lever being movable between a first position of holding and a second clamping position, the first lever and the second lever being able to retain the shoe in the base when they are in their first position, the first lever and the second lever being able to transmit a downward force respectively on the first retaining element and on the second retaining element when they are in their second position.
  • the first lever may be integral with the second lever, and the first lever and the second lever may be movable in rotation about the same axis of rotation, said axis of rotation being oriented parallel to a transverse axis of the fixing device, said axis being arranged at the rear of a base of the base.
  • the invention also relates to a sports shoe comprising a sliding assembled strap, the strap wrapping an instep of the shoe, the strap comprising a first free end, extending on a first side of the instep, and a second free end, extending on the other side of the instep, the first end comprising a first lateral retaining element intended to cooperate with a first lever of a binding device as defined above and the second end comprising a second lateral retaining element intended to cooperate with a second lever of the binding device to tighten the shoe against the binding device.
  • the first retaining element may extend transversely in an area of the shoe delimited by a rear end of the shoe, a lower edge of the shoe and a point of the shoe intended to be positioned at most about 20 mm from an internal malleolus of a user
  • the second retaining element may comprise transversely in an area of the shoe delimited by a rear end of the shoe, a lower edge of the shoe and a point of the shoe intended to be positioned at most approximately 20mm from a user's external malleolus.
  • the invention also relates to a fastening system comprising a fastening device as defined above and a sports shoe as defined above.
  • the equipment 1 comprises a sliding board 2, two binding devices 3 according to an embodiment of the invention and a pair of shoes 4 according to an embodiment of the invention.
  • the sliding board has an elongated shape, extends generally in a plane and has raised front and rear ends. A first face of the sliding board or lower face is intended to come into contact with a snowy surface while the two binding devices are fixed on the other face of the sliding board, that is to say on the upper face.
  • the two binding devices are used to fix the two shoes 4 of a user to the sliding board 2.
  • the two binding devices and therefore the two shoes are fixed substantially perpendicular to the axis along which the sliding board extends.
  • the binding devices may be fixed differently: for example, they may be fixed so that the binding devices and thus the two shoes form an angle other than a right angle with the axis in which the board extends. It is also possible for the user to adjust the orientation of each binding device on the board.
  • the binding devices could be attached side by side as for a monoski or one behind the other as for a skwal board.
  • the two binding devices could each be attached to a separate sliding board as for skiing.
  • the equipment could comprise only one binding device according to the invention, the other boot could then be attached to the sliding board via a binding device according to the state of the art. Subsequently, we will describe a particular binding device cooperating with a boot. This boot can be either a left boot or a right boot.
  • the longitudinal axis X of the binding device is defined as the axis in which the user's foot extends from heel to toe when the user's foot is in place in the binding device.
  • the terms "front” and “rear” are defined in relation to the longitudinal axis X, with the rear designating the heel side and the front designating the toe side.
  • the transverse axis Y designates an axis perpendicular to the X axis and oriented from left to right according to the user's point of view. For the purposes of the description, it is assumed that the device is mounted on a sliding board that rests on a horizontal ground.
  • the X axis and the Y axis therefore define a horizontal plane.
  • the Z axis designates the vertical axis, perpendicular to the X and Y axes.
  • the Z axis is oriented from bottom to top.
  • the X, Y and Z axes form an orthogonal coordinate system.
  • the shoe 4 is a high-top shoe. It envelops the user's foot, ankle and lower leg. In particular, the shoe 4 envelops the user's instep, i.e. the upper part of the foot above the ankle joint.
  • the instep 41 of the shoe refers to the part of the shoe covering the user's instep, i.e. a curved part of the anatomy, positioned in the area of the ankle joint between the foot and the lower leg.
  • the shoe 4 comprises a strap 42, or thong or "strap", assembled to slide relative to the rest of the shoe and surrounding the instep 41 of the shoe from left to right. In particular, the strap is sliding relative to an upper of the shoe, i.e.
  • This strap 42 covers the instep 41 of the shoe. It is connected and secured to the shoe. However, it would not be outside the scope of the invention if this strap were attached to a shoe initially not provided with a strap and secured to this shoe, for example, by a harness supporting the strap.
  • FIG 3 represents a sectional view of the shoe 4 and the fixing device 3 along a plane PC1 parallel to a median plane of the strap.
  • This plane PC1 is notably indicated on the figure 8 .
  • the strap 42 may have a generally U-shape, so as to properly wrap the instep 41. It comprises a first free end 43A extending from a first side of the instep on a lateral side of the shoe and a second free end 43B extending from the other side of the instep, on the other lateral side of the shoe.
  • the ends 43A, 43B may be substantially positioned at the level of the internal and external malleoli of the user's foot, these ends being substantially oriented towards a lower rear corner of the shoe, at the interface between the sole and the vertical part along the heel.
  • the plane PC1 forms with the horizontal plane an angle A1 which may be for example between 30° and 70°, in particular between 40° and 60°, preferably approximately 50°.
  • the first end 43A is provided with a first lateral retaining element 44A.
  • the second end 43B is provided with a second lateral retaining element 44B.
  • the two lateral retaining elements 44A, 44B are therefore substantially positioned in a ZR zone (represented in figure 10 ) of the shoe delimited by the rear end of the shoe, the lower edge of the shoe and two points of the shoe positioned respectively substantially opposite the internal malleolus and the external malleolus of the user's foot or advanced by possibly at most 20 mm relative to the malleoli.
  • the zone ZR extends laterally substantially on either side of the heel of the shoe, in a zone extending in the rear third of the shoe, defined relative to the total length of the sole of the shoe.
  • first lateral retaining element 44A and the second lateral retaining element 44B may be in the form of a lug extending transversely to the strap 42 from one side of the shoe, towards the outside of the shoe.
  • the lug may in particular have a cylindrical shape whose axis of revolution is substantially parallel to the Y axis.
  • the lateral retaining element could have a different shape, such as a mushroom shape.
  • the strap 42 is able to slide parallel to the direction in which it extends. The strap is forced to move at least according to this sliding movement. For example, its sliding may be guided by loops 45 covering it locally, for example two in number and each positioned on the lateral sides of the shoe.
  • the strap can rise slightly upwards and forwards when the shoe is not secured to the fastening device so as not to hinder walking, but can slide downwards and backwards when the strap is secured to the fastening device.
  • the strap 42 is then tightened by this fastening device to thus come to rest against the upper part of the shoe, at the instep.
  • these loops prevent the strap from twisting on itself.
  • the loops may be elements attached to the shoe or be formed by the upper of the shoe. It will not be outside the scope of the invention if other means of sliding and guiding the strap on or in the shoe are chosen.
  • the shoe could be designed differently: for example, the lateral retaining elements 44A, 44B could not be fixed directly to a strap but directly to the shoe and then be connected to the strap by means of a cable, these lateral retaining elements also having a sliding movement relative to the shoe.
  • the translational sliding of the strap 42 may allow the shoe to have a slight rolling movement from left to right about the X axis, when the shoe is secured to the binding device.
  • the strap 42 may also have an additional degree of freedom of movement, for example a rotation from front to back or vice versa to facilitate the rolling movement of the shoe secured to the binding device.
  • the retaining elements 44A, 44B could not be fixed to a strap of the shoe but directly to an upper of the shoe, to a sole of the shoe or to any other part of the shoe, and in particular to a reinforcement surrounding the heel.
  • the retaining elements would then only be movable relative to the rest of the shoe within the limit of the flexibility of the materials used to make the shoe.
  • the shoe could possibly include reinforcements to limit the movement of the retaining elements.
  • the retaining elements may have a shape and/or a location substantially identical to the shape and/or the location of the retaining elements integral with the strap presented previously.
  • the fixing device 3 is notably illustrated in perspective on the figure 4 . It comprises a base 10, a first lever 201 and a second lever 301, distinct from the first lever.
  • the first lever 201 is able to cooperate with the first lateral retaining element 44A and the second lever 301 is able to cooperate with the second lateral retaining element 44B to tighten the shoe against the base, in particular to tighten the strap 42 on the instep 41 of the shoe.
  • the first lever 201 forms a means of attaching the first retaining element 44A and the second lever 301 forms a means of attaching the second retaining element 44B.
  • the base 10 is fixed to the gliding board, for example by means of screws screwed into the thickness of the gliding board, or by any other means of rapid locking-unlocking, known from the prior art.
  • the base 10 or more precisely the lower plate of the base or base 11 may be provided with a circular opening (not shown), intended to receive a circular disk for retaining the base 10 on the gliding board.
  • the base 10 may also, in a known manner, be easily positioned angularly relative to the board.
  • the base 10 at least partially envelops a sole, a rear part and lateral sides of the shoe 4.
  • the base 10 comprises a base 11 intended to receive the support of the lower face of the sole of the shoe 4.
  • the base extends parallel to the gliding board and is positioned to bear on the latter.
  • the base 10 also comprises two lateral flanks 12A, 12B or lateral sides 12A, 12B extending on either side of the base 11, each in a plane parallel to the axes X and Z.
  • the lateral flanks make it possible to laterally block the shoe.
  • the two lateral flanks are spaced from each other so as to be able to accommodate the sole of the shoe.
  • the lateral flanks may have a height sufficient to bear on the sides of the sole of the shoe. In particular, they may have a height increasing from the front to the rear. They are connected to each other at the rear by an arch 13 in the shape of an arc of a circle raised relative to the base 11.
  • the arch 13 is intended to accommodate the rear of the shoe and can be positioned substantially at the height of an Achilles tendon of the user.
  • the arch 13 forms a rear stop for the shoe.
  • the fastening device could comprise any other type of rear stop means to prevent the shoe from moving backwards.
  • a rear opening is defined at the rear of the base by a lower contour of the arch, the two lateral flanks and the base. When the shoe is in place in the fastening device, the heel of the shoe can possibly come out through this rear opening.
  • the arch 13 can be surmounted by a vertical reinforcement or spoiler (not shown), extending at the rear of the shoe substantially along the Z axis, allowing the shoe to find support towards the rear of the base.
  • the first lever 201 is arranged along a lateral side (in this case the right lateral side) of the base 10 and towards the rear of the base.
  • the first lever 201 is arranged at the rear of the lateral flank 12A of the base and on the outer side thereof.
  • the lateral flank 12A is therefore interposed between the lever 201 and the shoe 4.
  • the second lever 301 is arranged symmetrically towards the rear and along an opposite lateral side of the base, i.e. along the lateral flank 12B of the base (in this case the left lateral side).
  • the first lever 201 and the second lever 301 can be positioned in a rear half of the binding device so as to be able to cooperate with the retaining elements 44A, 44B themselves arranged in the zone ZR of the shoe.
  • the two levers 201, 301 are movable between an initial position P0, a first position P1 and a second position P2.
  • the initial position P0 for putting on or ready to put on and the first position P1 called holding are identical but they could also be different.
  • the lever 201 and the lever 301 are movable in rotation about the same axis of rotation 14.
  • the axis of rotation 14 is oriented parallel to the transverse axis Y.
  • the axis of rotation 14 is arranged at the rear of the base 11 of the base, in the lower part of the base, so as to pass below the sole of the shoe when the latter is resting on the base 11.
  • the axis of rotation 14 can be guided in rotation by means of openings forming bearings in the base 10.
  • the lever 201 is integral with the lever 301 via the axis of rotation 14. More precisely, the lever 201 is integral with the axis of rotation 14 via a first end 14A of the axis of rotation 14 and the lever 301 is integral with the axis of rotation 14 via a second end 14B of the axis of rotation 14.
  • the rotation axis 14 therefore forms a means of connection between the two levers 201, 301.
  • a movement of the lever 201 causes an identical movement of the lever 301 and vice versa.
  • the user can therefore choose to manipulate either the lever 201 or the lever 301 depending on the movement that he considers most convenient to perform.
  • the two levers could be independent of each other, i.e. they could be moved between their different positions independently of each other and would be movable about two separate transverse axes, oriented along the Y axis and mounted on each of the lateral sides 12A, 12B of the base. If the two levers are independent, each foot is then held to the board by two independent attachment means.
  • the binding device may be symmetrical along a plane of symmetry PS oriented parallel to the longitudinal axis X and the vertical axis Z.
  • the same binding device may be used indifferently to attach a left shoe or to attach a right shoe to the sliding board.
  • the binding device may not be symmetrical with respect to a median plane and have a shape adapted for a left shoe and another shape adapted for the right foot.
  • the first lever 201 will simply be called “lever” and the first lateral retaining element 44A will simply be called "retaining element”.
  • Lever 201 is illustrated in more detail in the Figures 5 to 7 .
  • the lever may be a single-piece element. It may be made of metal to give it significant and constant strength and rigidity over time, but other rigid materials such as fiber-filled plastics could also be used. It extends generally in a plane perpendicular to the Y axis.
  • the lever 201 is movably mounted on the base by the rotation axis 14.
  • the rotation axis 14 is fixed to the lever 201 by being engaged in a circular opening 202, located at a lower edge of the lever 201. This circular opening 202 receives the end 14A of the rotation axis 14.
  • the lever 201 also comprises an opening 203, one of the edges of which forms a first bearing surface 204 or cam surface, capable of cooperating with the retaining element 44A.
  • the opening 203 is an opening passing through the thickness of the lever 201 along the transverse axis Y.
  • the edge forming the first bearing surface 204 is an upper edge of the opening 203 of the lever 201.
  • the retaining element 44A is retained vertically upwards when it is resting against a portion of the bearing surface 204 forming a cam.
  • This bearing surface 204 is perpendicular to a plane comprising the axis X and the axis Z.
  • the position of the retaining element 44A along the bearing surface 204 is visible from the outside, which in particular makes it possible to easily and quickly check the correct position of the retaining element relative to the bearing surface 204.
  • the opening 203 facilitates the evacuation of snow or ice which could accumulate at the level of the support surface 204.
  • the bearing surface 204 is notched, that is to say it comprises a row of notches 205A, 205B, 205C, 205D, 205E positioned side by side.
  • Each notch 205A, 205B, 205C, 205D, 205E comprises an arc shape, capable of matching the cylindrical shape of the retaining element 44A.
  • each notch can define a stable holding and/or tightening position of the lever 201, that is to say that the forces exerted by the retaining element on the lever cannot cause a rotation of the lever resulting in the opening of the lever in the direction of release D.
  • the chosen inclination of the support surface 204 which forms a cam surface and its positioning relative to the axis of rotation 14 of the lever 201 makes it possible, when a vertical upward force is applied by the retaining element of the boot when snowboarding on snow, to create a force which tends to rotate the lever 201 backwards, that is to say in the direction of closing and tightening.
  • the first support surface 204 comprises five notches but this number could be different.
  • the first portion 206 can be defined as the portion of the bearing surface corresponding to a first notch 205A and the second portion 207 can be defined as the portion of the bearing surface corresponding to a fourth notch 205D.
  • the second portion could correspond equally well to notches 205B, 205C or 205E.
  • the first position P1 called holding lever 201
  • the second position P2 called lever tightening, is notably illustrated on the figure 9 .
  • a backward rotation of the lever allows it to move from its first position to its second position.
  • the rotation of the lever in the tightening direction is represented in particular by an arrow S on the figure 9 .
  • the retaining element 44A of the shoe bears against the first portion 206 of the first bearing surface 204 when the lever is in its first position P1 and it bears against the second portion 207 when the lever is in its second position P2.
  • the bearing area of the retaining element on the first bearing surface gradually passes from the first portion 206 to the second portion 207, passing in particular through the notches 205B and 205C.
  • the distance D1 separating the first portion 206 from the axis of rotation 14 is strictly greater than the distance D2 separating the second portion 207 from the axis of rotation of the lever 201. From the first notch of the first portion to the last notch of the second portion, the distances separating these notches from the axis of rotation of the lever 201 decrease, then making it possible to bring the shoe retaining element closer to the base 11 of the base when the lever is tilted in the tightening direction S, towards the rear.
  • the lever is in its first position, called the holding position P1
  • the retaining element 44A is generally in the first upper notch 206
