Definitions

  • the invention relates to the field of boards for gliding for the practice of surfing on snow or water, skiing on snow or water, skateboard, or other.
  • a board traditionally has a length measured in a longitudinal direction between a first end and a second end, a width measured in a direction transverse between a first edge and a second edge, and a height measured between a bottom and a top.
  • a user asks for the board. This is particularly the case in snow surfing, or snowboarding, for example when the board is supported on an edge in a slope or when it advances in a bumpy area. Since the two feet are oriented substantially transversely to the board, the user performs in particular front edges on the side of the toes, rear edges of the side of the heels, or slips flat by example in the direction of the length of the board.
  • one of the aims of the invention is to improve the skid resistance of the board.
  • Another object of the invention is to reduce or eliminate the transmission of vibrations.
  • the invention proposes a sliding or rolling board having a length measured in a longitudinal direction between a first end and a second end of the board, a width measured in a direction transverse between a first edge and a second edge, and a height measured between a bottom and a top, the board having, from the first end to the second end, a first end zone, a first intermediate zone, a first retention zone, a second intermediate zone, a second retained, a third intermediate zone, and a second end zone.
  • the board according to the invention is characterized in that an edge of the board has at least one flexible portion and at least one rigid portion in the direction of the height of the board, the portions succeeding one another in the lengthwise direction. of the board.
  • the edge has a succession of projections and depressions at the level from below the board. These projections and these hollows are all the more numerous as the flexible and rigid portions are numerous. This means that the edge structure allows a discontinuous deformation in the direction of the height.
  • the protruding portions strongly support the ground, especially if it is hard snow or ice.
  • the corollary is that the recessed portions support little, if any, at all.
  • the surface of the projections being less than the surface of a complete edge, the board is in contact with the ground on a reduced surface. This is why the ground contact pressure of the board according to the invention is high, compared to a board according to the prior art. This high pressure favors a better inlay of the edge in snow or ice.
  • the first embodiment is presented with reference to FIGS. 1 to 5.
  • a snowboard 1 has a length measured in a longitudinal direction between a first end 2 and a second end 3. The longitudinal direction is marked with the axis central longitudinal Lo.
  • the board 1 also has a width measured in a transverse direction between a first lateral edge 4 and a second lateral edge 5, as well as a height measured between a gliding underside or face 6 and a receiving top or face. transversal direction is identified using the central transverse axis Wo.
  • transverse direction is perpendicular to the longitudinal direction, and is parallel to the sliding face 6.
  • the board 1 also has, from the first end 2 to the second end 3, a first end zone 8, a first contact line W1, a central zone 9, a second contact line W2, and a second zone of contact. end 10.
  • the central zone 9 itself comprises, successively, between the contact lines W1, W2, a first intermediate zone 15, a first retention zone 16, a second intermediate zone 17, a second retention zone 18, and a third intermediate zone 19.
  • Each retaining zone 16, 18 is provided to receive a user's foot restraint.
  • the devices, not shown, can be secured to the board 1 by means such as screws.
  • Each retaining zone 16, 18 is provided for this purpose with threaded orifices 20.
  • Each of the lines of contact W1, W2 is a line, substantially transverse to the board 1, at which the sliding face 6 touches a flat surface when the board 1 rests on the surface without external influence.
  • the general appearance of the board 1 is that of an elongated plate.
  • the underside 6 is slightly concave between the lines of contact W1, W2. It has a hollow or inner round which extends along the central zone 9, substantially from the first 15 to the third intermediate zone. In the embodiment shown, the rounding has a regular geometry.
  • the top 7 is generally convex in the central zone 9. It has two slight prominences represented by greater thicknesses in the retaining zones 16, 18. Also, the board is slightly reduced in width between the edges 4, 5 at the second intermediate zone 17. Of course, other embodiments may be provided.
  • the height of the board 1 is shown in section in FIGS. 2, 3 and 4.
  • the board 1 From the sliding face 6 to the receiving face 7, the board 1 has a sole 21, a first reinforcement 22, a core 23, a second reinforcement 24, and a protective layer 25.
  • the number of reinforcements can be changed and be less than or greater than two.
  • the board may not include any reinforcement or protective layer.
  • the sole 21 is made for example with a plastic material containing polyethylene.
  • the protective layer 25 is made, for example, of a plastics material containing an acetyl-butadiene-styrene.
  • each of the reinforcements 22, 24 is made from fibers impregnated with a resin.
  • the fibers may be made of any material, or any mixture of materials, such as glass, carbon, aramid, metal, or the like.
  • the core 23 comprises a main body 26 which gives it its general appearance.
  • the main body 26 comprises for example wood, a foam of a synthetic material, or any other material.
  • the reinforcements 22, 24 and the core 23 form a sandwich panel which extends at least 50% of the surface of the board, and preferably substantially over the entire surface.
  • the board 1 further comprises a first lateral spar 30 situated at the level of the first lateral edge 4, as well as a second lateral spar 31 situated at the level of the second lateral edge 5.
  • each spar 30, 31 delimits respectively at least partially the lateral edge 4, 5.
  • Each spar 30, 31 is located opposite the core 23.
  • each spar 30, 31 is connected directly to the core 23, to give unity to the inner part of the board, It also facilitates the manufacture, as well as the distribution of mechanical stresses.
  • it can alternatively be provided a separation between a spar 30, 31 and the core 23.
  • the width of the beams 30, 31 is substantially constant, again to facilitate manufacture.
  • the beams 30, 31 each extend between the first 22 and second 24 reinforcements, for example by ensuring a direct connection between the latter 22, 24.
  • additional elements for example between a spar 30, 31 and a reinforcement 22, 24.
  • the connection between the reinforcements 22, 24 would be indirect, in part at least.
  • each spar 30, 31 borders the core 23, which protects it from external aggressions such as shocks or infiltrations of water.
  • a spar 30, 31 is also used to transmit stresses related to the conduct of the board, especially when taking front edge or rear.
  • a spar 30, 31 comprises for example a synthetic material, such as an acetylbutadière-styrene.
  • each spar 30, 31 extends substantially over the entire length of the board. More precisely each spar 30, 31 extends from the first end 2 to the second end 3. This allows to taper the core 23 over the entire length of the board.
  • the rails 30, 31 extend one another to form a continuous peripheral belt 32. This facilitates the manufacture of the board, because a belt is easily placed in a mold.
  • the longitudinal members 30, 31 extend over only part of the board, for example only in the central area 9.
  • edge 33 which borders the sole 21.
  • the edge 33 is continuous but it could also be segmented, or not extend over the entire periphery. For example it could include a portion along the first edge 4 and a portion along the second edge 5.
  • the edge 33 preferably comprises a metal, or a metal alloy, such as steel, or the like.
  • an edge 4, 5 of the board 1 has at least one flexible portion 40, 41, 42, 43, 44, 45, 46 and at least one rigid portion 50, 51, 52, 53, 54, 55, 56, 57 in the direction of the height of the board, the portions succeeding one another in the direction of the length of the board.
  • each flexible portion 40, 41, 42, 43, 44, 45, 46 is respectively a portion of the spar having a recess 60, 61, 62, 63, 64, 65, 66, while each rigid portion 50, 51, 52 , 53, 54, 55, 56, 57 is a solid or non-recessed portion of the spar.
  • a recess 63 is a cavity in the spar 30 from the edge 4.
  • the recess 63 has an inlet 70, a bottom 71 and a periphery 72 or peripheral wall which connects the inlet 70 to the bottom 71.
  • the recess 63 is open on the side of the edge 4, but closed on the side of the core 23. Thus the latter remains protected from external aggression.
  • the board 1 has an alternation of sharply deformed and weakly deformed portions when taken from the edge.
  • This phenomenon is shown in FIG. 5, where the deformations of the lateral edge 4 give underneath a wavy appearance. Of course, this aspect is located at the edge 4.
  • the deformations of the spar, and therefore the edge 4 are elastic and reversible.
  • the ripple is formed during a catch of edge and disappears at rest. Thus, during the capture of the square, it is essentially the summits of the ripple which are embedded in the snow or in the ice.
  • the corollary is that the hollows of the undulation are not very encrusted, if at all. It follows that, when the edge is caught, the contact surface with the snow or the ice is reduced, and that the contact pressure increases. A consequence is a better grip of the board 1 on hard snow or ice.
  • One advantage of this is that untimely slippage is avoided, at least in many cases. Driving the board is easier.
  • the recesses 60, 61, 62, 63, 64, 65, 66 have for example an oblong shape with rounded ends. This limits the risk of cracks appearing in a spar. However other forms may be suitable, such as circles, squares, rectangles, or other.
  • the number of flexible portions 40, 41, 42, 43, 44, 45, 46 along an edge is seven.
  • two soft portions are provided in each of the first 16 and second 18 retaining zones, as well as three flexible portions in the second intermediate zone 17.
  • the alternation of flexible and rigid portions is therefore in the central zone 9, between the contact lines W1, W2. This zone 9 is the one that allows the catch of edge on steep slope.
  • the number of flexible portions along one edge may be two.
  • a first flexible portion extends along the first retention zone, and a second flexible portion extends along the second retention zone.
  • each recess may extend beyond a retaining zone 16, 18. This example is well suited to vibration damping at the feet of the user.
  • the recesses 60, 61, 62, 63, 64, 65, 66, and therefore the flexible portions 40, 41, 42, 43, 44, 45, 46, are distributed evenly. This allows a regular distribution of efforts when making a square. However it can alternatively be provided an irregular distribution, for example to customize the board.
  • the board 81 comprises a spar 82 at a lateral edge 83.
  • the spar 82 has at least one recess 84 which opens at the edge 83.
  • the recess 84 is filled, at least in part, by a stopper 85.
  • the latter is made of a flexible material relative to that constituting the spar 82.
  • the cap 85 comprises an elastically deformable foam of a synthetic material, such as a polyurethane or other.
  • the cap 85 protects the recess 84 against the intrusion of snow or ice, which preserves the flexibility of a portion in all circumstances.
  • the cap 85 also contributes to damping vibrations.
  • the cap 85 can provide a decorative function, particularly if its color differs from that of the spar.
  • the board 91 comprises a spar 92 at a side edge 93.
  • the spar 92 has at least one recess 94 which opens facing the core 95.
  • the recess 94 does not open on the side of the edge 93.
  • the interest of this construction is to give a surface continuity to the edge 93. This prevents any incrustation of foreign bodies.
  • a board 101 extends longitudinally between a first end 102 and a second end 103.
  • the board 101 also extends in width between a first edge 104 and a second edge 105, and in height between a below 106 and a top 107.
  • each of the recesses leads to both at the edge 104, 105 and above 107.
  • the board height variation at an edge 104, 105 is achieved by the fact that the thickness of the spar 130 varies along the board.
  • the spar 130 has the same height as the core 131, while in Figure 10 the spar 130 has a reduced thickness. Since the lower 132 and upper 133 reinforcements are connected to both the core 131 and the spar 130, the height of the plank at the edge 104, 105 follows the thickness of the spar. Where the thickness is reduced, the board is relatively flexible in height, whereas where the thickness is preserved, the board is more rigid. It is noted in addition that the core 131 refines gradually when the spar has a reduced thickness. This gives continuity over 107.
  • the board 101 Since the thickness of a spar is reduced and increases successively several times along an edge 104, 105, the board 101 has a corrugation when making a edge. Of course depressions are formed on the underside 106 of the board 101, at the edges 104, 105, where the recesses are made. By corollary vertices are formed where the spar 130 has retained a thickness equal to that of the core. Again the ground contact area is reduced, and the pressure and grip are stronger.
  • a board 141 extends in height between a bottom 142 and a top 143. At least one recess 144 is formed at a side edge 145. The recess 144 opens both to the top and to the edge. To form the recess, the reinforcements join directly. There is no portion of spar where the recess 144 is present. Thus the board 141 is even more flexible at the level of the recess 144.
  • a board 151 extends in height between a bottom 152 and a top 153.
  • the board 151 comprises a sole 154, a lower reinforcement 155, a core 156, an upper reinforcement 157, and a protective layer 158.
  • the lower reinforcements 155 and upper 157 join directly.
  • the recess opens to the top 153 and to the edge 160.
  • the recess corresponds to a flexible portion of the edge of the board.
  • the upper reinforcement 157 is extended to the lower reinforcement 155 by a fold 161.
  • the latter is parallel to the edge 160, and ensures the transmission of pulses driving.
  • the board 151 according to the sixth embodiment of the invention, is devoid of spar. It is the variation of curvature of the upper reinforcement 157 which creates the succession of flexible and rigid portions. This corresponds for the plate 151 to a hull type structure.
  • the invention is made from materials and according to implementation techniques known to those skilled in the art.
  • any board it can be provided different forms of recesses. These are compatible with any type of board construction, such as a shell, a sandwich, a box, or other.
  • the soft portions may be evenly distributed along an edge or, on the contrary, irregularly.
  • the flexible portions may also be made by recesses which open on the underside and on the edge of the board.
  • a spar is formed of several successive portions, which comprise different materials. Of course, some materials are more flexible than others. The portions may be juxtaposed or separated.
  • a recess can be plugged, partially or completely, with a plug itself hollow. That is, the cross section of the plug is hollow. This helps to lighten the plug, and therefore the board.
