Abstract
Description
- The present invention relates to the field of gliding boards adapted to snowboarding.
- A snowboard has a length demarcated by a first end and a second end, a width demarcated by a first edge and a second edge, as well as a height demarcated by an upper surface and a lower surface or gliding surface.
- To operate the board, a user has both feet affixed to the upper surface along a substantially transverse direction of the board. Conventionally, the end zones of the board are thinned down so as to deform during the operation. The deformation of an end zone enables the board to accumulate then to restore energy, in the manner of the end of a blade-shaped spring. Therefore, the user, for example, can cause the elastic deformation of one end, by applying an impulse after shifting the weight of his body toward the end. The energy recovered during the impulses makes it easier to negotiate certain curves or to perform jumps.
- The thinning of an end zone is obtained by making a core that is beveled toward each end of the board.
- The core is then covered with various layers of materials to obtain the structure of the board.
- It is known to select low-density materials to manufacture the core, in order to reduce the board mass. For example, the core can be made of wood, or of a foam of a synthetic material.
- The core is shaped by machining an originally flat raw piece. The machining generates mechanical stresses in the raw piece, which tend to tear out portions of the core at the ends. The tearing occurs because the core is very thin at the ends. Therefore, it is necessary to select a material that has an adequate mechanical strength to make a core.
- This means that certain low-density materials cannot be used to make a core, due to the fact that they cannot be machined.
- This is especially true with wood, in the case where the wood fibers are oriented in the direction of the board thickness.
- This is also true with honeycombed materials, such as those in which each of the juxtaposed cells is hexagonal.
- The object of the invention more particularly is a board whose core can be made out of any low-density material.
- According to the invention, a gliding board adapted to snowboarding has a length measured along a longitudinal direction between a first end and a second end of the board, a width measured along a transverse direction between a first edge and a second edge, and a height measured between an upper surface and a lower surface or gliding surface, the height in particular including a lower reinforcement, an upper reinforcement, and at least one core located between the upper reinforcement and the lower reinforcement, the board also having, from the first to the second end, a first end zone, a first contact line, a first intermediate zone, a first retaining zone, a central zone, a second retaining zone, a second intermediate zone, a second contact line, and a second end zone.
- The board according to the invention is characterized in that the thickness of each core is demarcated by two surfaces of the core parallel to one another, and in that at least one of the cores has a smaller width than the width of the board in each end zone.
- This means that the thickness of the core is constant, and that the ends of the core are not beveled. The thickness of the core remains sufficient so that a machined raw piece keeps all of its portions, regardless of its constituent material.
- For example, it is possible to make the core out of wood in order that the wood fibers be oriented in the direction of the board thickness. The advantage is that this orientation of the fibers improves the crushing strength of the board, in the direction of the thickness.
- It is also possible to manufacture a honeycombed core from a metal such as aluminum, or from a plastic material. The advantage is that the board obtained is lighter than a conventional board and has an increased crushing strength.
- In any event, the reduced width of at least one of the cores, at the end zones, enables the board to deform in order to accumulate and restore energy.
- Other characteristics and advantages of the invention will be better understood from the description that follows, with reference to the annexed drawings showing, by way of non-limiting examples, how the invention can be embodied, and in which:

- FIG. 11 is a view similar to FIG. 2, according to a seventh embodiment.
- The first embodiment of the invention is described hereinafter by means of FIGS.1-5.
- In a known fashion, as seen in particular in FIG. 1, the
snowboard 1 has a length measured along a longitudinal direction L1 between afirst end 2 and a second end 3. Theboard 1 also has a width measured along a transverse direction between a first lateral edge 4 and a secondlateral edge 5, as well as a height measured between anupper surface 6 and a lower surface orgliding surface 7. - Of course, the transverse direction is perpendicular to the longitudinal direction L1, and parallel to the
gliding surface 7. - The
board 1 also has, from thefirst end 2 to the second end 3, afirst end zone 8, a first contact line W1, a firstintermediate zone 9, afirst retaining zone 10, acentral zone 11, asecond retaining zone 12, a secondintermediate zone 13, a second contact line W2, and asecond end zone 14. - Each
retaining zone board 1 by a means such as screws. Eachretaining zone openings 15. - Each of the contact lines W1, W2 is a substantially transverse line of the
board 1, at the level of which thegliding surface 7 contacts a planar surface when theboard 1 is placed on the surface without any external influence. - The height of the
board 1 is shown in cross-section in FIG. 2. From thegliding surface 7 to theupper surface 6, theboard 1 has a sole 16, alower reinforcement 17, acore 18, anupper reinforcement 19, and aprotective layer 20. - The sole16 is preferably made out of a plastic material containing polyethylene. The
protective layer 20, for example, is made of a plastic material containing acetyl-butadien-styrene. - Each of the
reinforcements core 18 is made of a low-density material, which makes it possible to reduce the mass of theboard 1, as will be explained hereinafter. - According to the invention, as understood in particular by means of FIGS.3 and 4, the
core 18 of theboard 1 has a constant thickness. This means that regardless of the area of the board where the core thickness is measured, the resulting value is the same, except for the manufacturing tolerance. - As shown in FIG. 3, the
upper surface 6 of theboard 1 has abase plate 21 projecting with respect to abase surface 22. The distance separating thebase surface 22 from anupper surface 23 of thebase plate 21 is constant, because the thickness of thecore 18 is constant, and because the thicknesses of the sole 16,protective layer 20 andreinforcements base plate 21 is substantially the same as that of thecore 18. - The
board 1 is incurved so as to contact the previously mentioned planar surface only at the level of the contact lines W1, W2. The surface is designated by the reference character G. - The
core 18 is shown alone in a side view in FIG. 4. It is made of a raw piece such that itsupper surface 24 andlower surface 25 are parallel. - The
core 18 can be made of wood arranged such that its fibers are oriented substantially perpendicular to the upper 24 and lower 25 surfaces. In this case, thecore 18 is preferably obtained by flat machining, by facing theupper surface 24. This method has the advantage of being economical. - Given that the thickness of the
core 18 is constant, the edges of the core are not torn out during machining. It is possible to use a wood such as balsa, whose density close to 0.15 is lower than that of conventional wood, such as birch or poplar. As a result, theboard 1 is lighter. In addition, the vertical orientation of the wood fibers increase the crushing strength of theboard 1, even if the wood selected is balsa or an equivalent wood. - The
core 18 can also be obtained with a honeycombed structure whose cells are perpendicular to the upper 24 and lower 25 surfaces. This can be a honeycombed structure, for example. One also notes a decrease in the mass of theboard 1 and an increase in the compressive strength in the direction of the thickness of the board. - Of course, the core18 can be made of other materials.
- The width of the
core 18 varies between itsfront end 26 and itsrear end 27. - The variation in the width of the
core 18 translates into a similar variation in the width of thebase plate 21, as is clearly seen in FIG. 5, in particular. - From the
end 2 to the end 3 of theboard 1, thebase plate 21 and the core 18 have a symmetrical shape with respect to a longitudinal median plane that is illustrated by the axis line of the longitudinal direction L1. Thecore 18 andbase plate 21 each extend widthwise from the longitudinal median plane, and on both sides of the latter. - The
base plate 21 has afirst end 28 located in the vicinity of thefirst end 2 of theboard 1, as well as asecond end 29 located in the vicinity of the second end 3 of theboard 1. - In each of the
end zones board 1, thebase plate 21 and the core 18 widen out between theend - Next, the
base plate 21 and the core 18 continue to widen out from the contact line W1, W2 up to the retainingzone intermediate zone contour 30 of thebase plate 21 remains in the vicinity of thelateral edges 4, 5 of theboard 1 in the retainingzones base plate 21 and the core 18 narrow down toward the middle of theends base surface 22. - The
core 18 and thebase plate 21 still have a width smaller than or equal to the width of theboard 1 measured between thelateral edges 4, 5. - In the
end zones core 18 and of thebase plate 21 are preferably comprised between 20 and 60% of the width of theboard 1. - In the
intermediate zones core 18 and of thebase plate 21 are preferably comprised between 40 and 80% of the width of theboard 1. - In the retaining
zones core 18 and of thebase plate 21 are preferably comprised between 75 and 100% of the width of theboard 1. - Finally, in the
central zone 11 of theboard 1, the widths of thecore 18 and of thebase plate 21 are preferably comprised between 50 and 90% of the width of theboard 1. - The decrease in the width of the core18 at the level of its
ends ends 2, 3 of theboard 1, provides theboard 1 with substantially the same ability to deform in bending along a transverse axis of theboard 1 as in the case of a conventional board. - The assembly of the constituent elements of the
board 1 is done in a conventional manner. The sole 16,lower reinforcement 17,core 18,upper reinforcement 19, andprotective layer 20 are stacked in a mold. Next, a raise in temperature and pressure causes the affixation of the elements. - The other embodiments of a board according to the invention will be described respect to the first embodiment are shown. For this reason, each of the Figures serves to show an embodiment, the Figure being a cross-section similar to FIG. 1.
- The second embodiment is shown by means of FIG. 6.
- A
board 40 has a height that includes a sole 41, alower reinforcement 42, anintermediate reinforcement 43, acore 44, anupper reinforcement 45, and aprotective layer 46. During the manufacture of theboard 40, it can be provided to first obtain a sub-assembly including only theintermediate reinforcement 43,core 44 andlower reinforcement 45. Next, the sub-assembly is arranged in a mold with the remaining components to obtain theboard 40. - The third embodiment is shown by means of FIG. 7.
