Definitions

  • the invention relates to the field of devices for retaining a shoe on a Snowboard intended for snowboarding.
  • a board intended for the practice of snowboarding, or snowboarding presents a length delimited by front and rear ends, as well as width delimited by first and second side edges.
  • a user has both feet retained on the board, the feet each being oriented substantially in the width direction of the board. This means that the front end of each foot is located substantially at the level of one of the side edges, and that the rear end of each foot is located substantially at the level of the other of the lateral edges.
  • the board is driven by movements of the user's body.
  • a device for retaining a shoe on a board is provided a wedge, the latter being arranged so as to be located under the sole of the shoe at level of one end of the foot.
  • the wedge makes it possible to raise the end of the foot relative to to the other parts of the foot.
  • the user must therefore perform very rapid movements with the body to keep his balance, movements that are difficult to achieve and that disturb driving. It follows that the control of the trajectories of the board is difficult.
  • the invention particularly relates to a device for retaining a shoe on a gliding board, which increases the lateral inclination of the board for support given, and which allows the board while driving to pass without brutality from a position where it is flat on snow at a position where it is tilted relative to the surface of the snow, or vice versa.
  • a device for retaining a shoe on a sliding board intended for practice snowboarding comprises a base and means provided for retaining the shoe above an upper face of the base, the device extending in a longitudinal direction and successively having a front end zone, a zone central, and a rear end zone, the device further comprising at least one wedge designed to receive an end portion of the sole of the shoe, the wedge being positioned at one of the end zones.
  • the device is characterized by the fact that the wedge has a first layer produced with a substantially non-deformable material, the thickness of the first layer increasing away from the central area, and by the fact that the wedge has a second layer juxtaposed with the first layer, the second layer being made with a material substantially deformable, the thickness of the second layer decreasing in one direction away from the central area, the wedge projecting from the upper face of the base.
  • the user is therefore not unbalanced and can maintain control over the trajectories of the board.
  • a device 1 is attached to a gliding board 2 to hold a shoe on board 2.
  • a gliding board 2 For convenience, the shoe is mounted in other figures, and plate 2 is shown only in part.
  • the device 1 comprises a base 3 and means provided for retain the shoe above an upper face 4 of the base 3.
  • the shoe retaining means include for example a front link 5, a instep link 6, a rear arch 7, and a cuff 8.
  • the links 5, 6 are each connected by one end to a lateral edge 9 of the device 1, and by another end to another edge side 10 of the device 1.
  • the links 5, 6 can be respectively opened or closed, by example using removable locking mechanisms 11, 12.
  • the arch 7 is also connected to each of the lateral edges 9, 10. As for the cuff 8, it is articulated on the hoop 7 along an axis 13 oriented in a transverse direction of the device 1.
  • a user After having opened the links 5, 6 using the mechanisms 11, 12, a user poses the shoe 14 on the device 1, so that the sole 15 is in contact with the face upper 4, and so that the heel 16 is in contact with the hoop 7. The upper part of the upper 17 of the shoe 1 is then in contact with the cuff 8.
  • the device 1 extends in a longitudinal direction L, the base 3 being delimited in this direction by a front end 18 and by one end rear 19.
  • the longitudinal direction L must be understood as being a direction substantially perpendicular to the transverse direction along the axis 13.
  • the device 1 successively has a front end zone 20, a zone central 21 and a rear end zone 22.
  • the device 1 is secured to the board 2 by a fastening means shown in the form of a disc 23, the latter being situated at the level of the central zone 21.
  • the disc 23 retains the device 1 on the board 2 so that a lower face 24 of the base 3 is in contact with a face upper 25 of the board 2.
  • the disc 23 has for example the shape of a truncated cone.
  • fixing means represented in the form of screws retain the disc 23 on the board 2.
  • the disc 23 and the means for fixing it to the board 2 are not described in more detail here, as they are well known to those of skill in the art.
  • the device 1 is oriented substantially in a transverse direction of the board 2. This means that the front end region 20 of the device 1 is located near an edge lateral 26 of the board 2, and that the rear end zone 22 of the device 1 is located near a side edge 27 of the board 2.
  • the distance between the edges 26 and 27 defines the width of the board 2.
  • the device 1 is provided with a wedge 28 located at the level of the front end region 20 under the front end of the shoe.
  • the wedge 28 allows the user to press on board 2 with the front end of the foot.
  • the wedge 28 extends between a front end 29 and a rear end 30 along the longitudinal direction L of the device 1, and between two lateral edges 31, 32 in the direction transverse of the device 1.
  • the wedge 28 still has a thickness delimited between a face upper 33 and a lower face 34.
  • the implantation of the wedge 28 on the device 1 can for example be carried out by a mechanical means, such as an interlocking, as explained below.
  • the shim 28 has a groove 35 delimited by a portion of the rear end 30, a tongue 36, and a ridge 37 projecting from the language 36.
  • the crest 37 is housed in a groove 38 of the base 3, and a crest 39 of the base 3 is housed in the groove 35 of the wedge 28. It follows that the wedge 28 is attached to the base 3.
  • the shim 28 is wedged in the transverse direction of the device 1 by edges 40, 41 of base 3 in contact respectively with edges 31, 32 of the hold 28.
  • the wedge 28 is in a position fixed relative to the base 3.
  • the lower faces 34 of the wedge 28 and 24 of the base 3 are parallel.
  • the wedge 28 is produced by superimposition of at least two layers of materials different from each other.
  • the wedge 28 has a lower layer 42 made of a material which is substantially undeformable. This means that the layer 42 practically does not deform when an effort is exerted on it by the user while driving the board 2.
  • the material constituting the layer 42 may be a hard plastic material, reinforced or not, wood, metal, metal alloy or other.
  • the plastic may include polycarbonate, polyethylene, polyamide, or even a rubber resistant to deformation. In this case the hardness of the rubber is preferably between 10 Shore C and 90 Shore D.
  • the thickness of the lower layer 42 increases in a direction away from the central zone 21.
  • an upper face 43 of the layer 42 is inclined relative to the face lower 24 of the base 3.
  • the lower 34 and upper 43 faces of the layer 42 form between them an angle of a few degrees.
  • the angle can be between 5 and 45 degrees.
  • the wedge 28 also has an upper layer 44 made with a material substantially deformable. This means that the layer 44 deforms when an effort is exercised on it by the user while driving the board 2.
  • the material constituting the layer 44 may be a flexible cellular plastic material or no. In this case, it can include the same compounds as the lower layer 42, these compounds then having an internal structure which gives the upper layer 44 its deformability. Of course, the deformation of layer 44 is elastic and reversible. This means that when the user exerts no more effort, it resumes its shape initial.
  • the thickness of the upper layer 44 decreases in a direction away from the zone central 21.
  • the thickness of the layer 44, at the level of the front end 29, is more less than the thickness of the layer 44 at the rear end 30.
  • the upper layer 44 is superimposed on the lower layer 42 by contact with a face lower 45 with the upper face 43 of the layer 42.
  • the faces 43 and 45 are joined to each other by a means such as bonding.
  • the lower face 45 of the upper layer 44 is therefore inclined, relative to the face 24 of the base 3, by the same angle value as the face upper 43 of the lower layer 42.
  • the upper layer 44 also has an upper face 46 which is preferably substantially parallel to the underside 34 of the wedge 28.
  • a protective layer 47 the substantially constant thickness of which is defined by a share by an upper face which merges with the upper face 33 of the wedge 28 and other part by a lower face 48, is superimposed on the upper layer 44.
  • the layer of protection 47 is secured, by its lower face 48, to the upper face 46 of the layer upper 44 by a means such as bonding.
  • the layer 47 has a reduced thickness compared to the thickness of the shim 28, and is made with a material that has good abrasion resistance.
  • This material can be relatively flexible or relatively rigid.
  • a plastic may be suitable.
  • each of the lower 42, upper 44, and protective 47 layers is constant, depending on the direction transverse of the device 1, in a given section plane.
  • the thickness of the shim 28 is greater than the thickness of the base 3, delimited by the upper 4 and lower 24 faces.
  • the thickness t1 of the base 3 is between 2 and 5 mm, while the thickness t2 of the shim 28 is between 5 and 20 mm.
  • the upper face 33 of the wedge 28 is therefore more distant, relative to the face upper 25 of the board 2, than is the upper face 4 of the base 3. This amounts to say that the wedge 28 is projecting relative to the face 4 of the base 3.
  • the support of the shoe 14 on the wedge 28 modifies the shape of the wedge 28.
  • the shoe 14 is a shoe whose sole 15 and upper 17 have a some flexibility. This means that the sole 15 is deformed during walking to ensure a smooth running of the foot.
  • the sole 15 also deforms while driving the board 2.
  • the plate 2 is in contact, through a lower face or gliding sole 49, with a snow surface 50.
  • the board 2 is substantially flat on the snow. This is produced for example when the board 2 slides in the direction of the longitudinal direction L.
  • the user then has the feet which press towards the board 2 as well at the level of the end front of the foot, only at the rear end of the foot. This means that the weight of the user is distributed in a substantially homogeneous manner over the entire surface of the sole 15.
  • the shoe 14 retains the shape which it naturally has when it is not used.
  • a front end 51 of the sole 15 has a shape raised at the front of the shoe 14. This shape makes it possible to avoid friction of the shoe 14 in snow while driving.
  • the board 2 is inclined to the snow at an average angle value.
  • FIG. 8 corresponds to a curve with a small radius of curvature.
  • the board 2 is then inclined with respect to the snow at a large angle value. Support with the front end of the feet increases the sinking of the edge 26 in the snow, as well as the deformation of the sole 15.
  • the damping decreases in proportion to the reduction in thickness of the upper layer 44 between the ends 30 and 29 of the wedge 28.
  • the shim 28 deforms reversibly. It follows advantageously that the user can move from one driving position to another without brutality.
  • a retaining device 60 retains the boot 14 on the board 2. It does not differ from the device according to the first embodiment only by the fact that it is provided with two wedges 61, 62.
  • a wedge 61 is located in a front end region 63 of the device 60, while the other wedge 62 is located in a rear end region 64.
  • Each of the wedges 61, 62 is structured like the wedge 28 of the first mode for exercising the same functions.
  • the wedge 61 reacts with respect to the supports of the front end of the foot, while the wedge 62 reacts with respect to the supports of the rear end of the foot.
  • it is the edge 27 of the board 2 which sinks into the snow.
  • a wedge 70 comprises a non-deformable lower layer 71 to which is superimposed a deformable upper layer 72, to the exclusion of any protective layer.
  • the shim 70 has the same characteristics as the shims 28, 61, or 62 of the first and second embodiments. It has the advantage of being more economical to manufacture.
  • a device could be provided with a single wedge at the rear, that is to say at the rear end of the foot.
  • a shim could be replaced by several smaller shims located next to each other.
  • the internal structure of a hold may have different shapes to fill the same functions.
  • a shim can be placed directly on the upper face of the base 3, that is to say without being in direct contact with the board.
  • the wedge 28, 61, 62, 70 may have an upper face 46 and a lower face 34 inclined one relative to each other, so that the thickness of the shim measured at its end front 29 is greater than the thickness of the shim measured at its rear end 30.
