Definitions

  • the invention pertains to surfboards and more particularly to a surfboard having a narrow waist, and lacking fins.
  • Conventional surfboards have one or more fins located in the tail section. These fins provide a certain degree of stability but detract from the surfboard's ability to be surfed backwards. The fins may also interfere with some aerobatic or acrobatic capabilities of the board.
  • a central portion of the rail is, to some degree, concave.
  • Figure i is a top plan view of a surfboard made in accordance with the teachings of the present invention. Only half of the top plan is shown.
  • Figure 2 is a side elevation of the board depicted in Figure i;
  • Figure 3 is a bottom plan view of the surfboard depicted in Figure i illustrating the central concave portion that defines a central flow channel;
  • FIGS. 4(a)-(h) are transverse cross sections also indicating their longitudinal position with respect to the plan view illustrated in this figure;
  • Figures 5(a)-(h) are cross sections of the concave portion of the rail illustrating various suitable embodiments
  • Figure 6 is a top plan view of an alternate embodiment of the invention.
  • Figure ⁇ illustrates two bottom plan views depicting the utilisation of auxiliary channels.
  • a surfboard io comprises a construction such as a conventional construction with a foam core to which a fibreglass or other • composite exterior is applied.
  • the rounded front of the surfboard Ii is similar to the rear of the surfboard 12. It need not be identical.
  • the board is characterised by a narrowing waist portion 13.
  • the narrowing waist 13 creates lateral lobes 14, 15,
  • the degree of concavity of the waist 13 in plan view is determined by the dimension Y.
  • the dimension V may be determined by a number of factors including the length of the board, the type of waves that are to be ridden and the board rider's preferences.
  • the board has a generally uniform rocker or bottom curvature 21. It may be flatter in the middle.
  • the board is characterised by a certain degree of nose lift "h" and tail lift “g". In some embodiments, the nose lift "h" is greater than equal to one half of the tail lift "g”.
  • the thickness at each end of the board 22, 23 is generally less than the thickness 24 in the middle of the board.
  • Figure 2 also illustrates that the board lacks fins. In alternate embodiments, front or rear fins may be required to provide optional and enhanced stability or turning ability.
  • the underside of the board 31 evidences a centrally located concave rail section 32 in the side rails,
  • the lowest surface 32 of the concave portion is lower than the underside 33 of the surfboard. It may project below the underside 33 by 5-5omm although it will be understood that this maximum drop from the underside may taper from a maximum near the middle of the rail 34 toward a minimum at the longitudinal extremes of the central concave section of the rail 35, 36-
  • the rail preferably does not extend beyond the maximum width of the front and rear lobes 37, 38.
  • the area between the rails 32 defines a central "hour glass" shaped channel 39 that may be flatter than the rails.
  • FIG 4 the geometry of the board 10 is explained with reference to various transverse cross sections 4(a)-4(h). As depicted in cross sections 4(a) and 4Q1), the front and rear of the board 41, 42 are fairly conventional in cross section.
  • Figure 4(b) illustrates that there is a certain amount of deck roll off 43 that is located between the front 42 and the maximum width at the first lobe "a”.
  • Figure 4(c) shows a cross section close to the maximum front lobe "a”.
  • the side rail 44 now extends below the bottom surface 45 and creates a small concave area 46. As shown in Figure 4(d), the concave area 46(a) is more pronounced in the region between the maximum front lobe width "a" and the narrowed waist "y”.
  • the extreme tip of the rail 47 is also somewhat blunted with respect to the rail tip depicted in Figure 4(c).
  • the concave area 46(b) of the rail is even more pronounced and at this point the rail reaches its maximum elevation below the lower surface 45.
  • the interior "grab" depth of the rail may reach a distance of 5-5omm.

  • the cross section shown in Figure 4(g) is similar to that depicted in Figure 4(c),
  • FIG. 5(a)-5(h) illustrate a variety of typical rail geometries that could be substituted for the rail geometry depicted in Figure 4(e), that is generally representative of the maximum extent of rail concavity.
  • Figure $(a) illustrates a mild concave portion Sl and a fairly sharp rail tip 52 which is turned down and out from a relatively flat deck 53. The upper surface of the rail 54 being gently rounded. As shown in Figure s(b), the concavity 55 is more pronounced and the rail tip 56 is somewhat sharper and turned in.
  • the outer grab radius of the rail 57 also "turns under" more than the embodiment depicted in Figure 5(a).
  • the concavity 58 is well pronounced and the rail includes a sharp edge 59 located between two flat portions 60, 61 that define the underside of the rail.
  • Figure 5(d) illustrates a rail having a concave portion 61 and a lateral flat portion 62 that are separated from one another by an edge 63.

  • Figure 5(1) illustrates a tapered rail 68 that narrows to an edge 69 and that incorporates a modest concave portion 70.
  • Figure s(g) illustrates a rail 71 with a more aggressive concave section 72. Notice that the rail's edge 73 is "turned in” or directed inwardly toward the centre line of the board.
  • Figure 5(h) illustrates a rail 74 having a generally flat bottom 75 characterised by a pair of lateral edges 76, 77, The interior edge 77 is located between the flat portion 75 and the concave area 78.

  • FIG. 7(a) illustrates curved channels 91 that create multiple flow paths that originate in a central region 92 of the board and extend, symmetrically toward the side edges 93 that form the rear of the board, These channels or chines 91 enhance the board's turning ability and compensate for the board's minimisation or lack of fin area.
  • Figure 7(b) illustrates straight channels 94 which extend from the mid line of the board 95 toward the side edges 96 at the rear of the board.

Abstract

La présente invention concerne une planche de surf avec une partie centrale rétrécie ayant une aire élargie (lorsque regardée en plan) devant et derrière la section centrale et se rétrécissant vers chaque extrémité. La partie centrale étroite (« en forme de sablier ») permet de tourner la planche de surf en utilisant la forme du rail latéral (bord) et en minimisant ainsi ou en rendant superflue l’utilisation de dérives. Le nez et la queue de la planche sont de forme similaire, tournant vers le haut à chaque extrémité pour permettre au surfeur de surfer vers l’avant ou vers l’arrière plus facilement qu’avec les planches de surf traditionnelles. La planche de surf peut également comprendre des canaux en dessous, prenant une forme parabolique rayonnant de la partie centrale de la planche vers les bords extérieurs en direction de chaque extrémité. Ces canaux créent des arêtes plus prononcées au niveau des sections plus larges, vers l’avant et l’arrière étant donné que le centre de la partie inférieure de la planche a une profondeur de canal minimale. Les canaux et les arêtes contribuent à la traction de la planche dans l’eau afin de donner au surfeur un plus grand contrôle dans les virages.
