Definitions

  • the present invention generally relates to water skis and more particularly to adjustable shoes which serve as water skis.
  • Buoyant forces resulting from displacing relatively large volumes of water may be used to support a person, but this is of course not water skiing.
  • Such "water walking" apparati are disclosed in U.S. Patent Nos. 1,275,727, 1,413,602, 3,108,296, 3,833,956, 3,936,897, 4,117,562, and 4,261,069.
  • US-A-4227274 discloses a piggy back ski comprising a first ski section secured to a second ski section. Water skiing is possible with both the first and second ski sections and with the first ski section alone. The first ski section lacks a channel means for providing guidance. Additionally, the first ski section has a generally uniplanar sole, which makes it inconvenient for use during a start-up of a skiing session.
  • Another object of the invention is to provide an adjustable water ski shoe which will fit many sizes.
  • the applicant's water ski shoe comprises the features set forth in claim 1. Preferred embodiments of the invention are disclosed in the dependent claims. Specifically, the rear end of the sole converges to a point to better "cut” the water and for better balance.
  • the foot plate is pressed onto the sole and is designed to conform to the shape of a skier's foot.
  • the boot portion of the water ski shoe is made of silicon rubber. A small rubber wings may be attached to the boot for aerodynamic stability.
  • the water ski shoe may be adjustable so that the heel and toe may converge or move apart by sliding on a track system which locks at incremental segments.
  • the length of the shoe may be further fixed by use of Velcro TM straps attached to the heel section and fastened to strip-mating straps on the toe section.
  • a water ski shoe 1 as shown in Fig. 1 broadly comprises a boot 10, and a sole 20.
  • the sole 20 is preferably made of a rigid fiberglass composite of a well known type and is curved upwards (away from the water surface) at its toe and heel ends (21, 22) to facilitate gliding on the water. Heel end 22 of the sole 20 includes certain contour features which facilitate directional stability and better balance while skiing.
  • a foot plate 25 which is designed to conform to the shape of a typical skier's foot (not shown).
  • the footplate 25 and boot 10 may come in several sizes, although every size on half-size increments may not be necessary.
  • Foot plate 25 is typically made of magnesium or similar metal and is molded into the top 23 of the fiberglass sole 20 during the molding process. It may alternatively be riveted or screwed or held by adhesive.
  • an inverted V-shaped water channel 30 Built into the bottom 24 of fiberglass sole 20 is an inverted V-shaped water channel 30 (see Figs. 3 and 4) substantially parallel to and along center line 31 of the sole 20 to help prevent the water ski shoe 1 from gliding randomly on the water surface 3.
  • the water channel 30 runs much of the length of the sole 20 (see Fig. 3).
  • a projection 26 Near the heel end 22 of the underside 24 of the fiberglass sole 20 is a projection 26 having the shape of an oblate spheroid which, among other things, disperses water which has travelled through the channel 30.
  • pressure holes 27 are drilled along two parallel axes (shown as dashed lines 28 and 29 in Fig. 3) on each side of the water channel 30.
  • the holes 42 are drilled into the bottom 24 of the fiberglass sole 20 and are paired such that each pressure hole 27a along axis 28 will have a corresponding pressure hole 27b along axis 29.
  • the pressure holes 27 are drilled into the bottom 24 of the fiberglass sole 20 at a sufficient angle to "meet" the water channel 30 and serve as an outlet for water which has entered the water channel 30 as shown in Fig. 4.
  • the pressure holes 27 may also be drilled at such an angle that water expelled through the pressure hole will enhance the volumetric flow of water towards the rear of the shoe 1.
  • the boot 10 is preferably made of silicon rubber. Rubber straps 11 are adapted to the top 12 of the boot 10 and are secured by typical buckles (not shown).
  • a rooster tail 40 may be generated by water ski shoe 1 passing along the water, by directing water channel 30 which passes through projection 26, and outwardly and upwardly through heel portion 22 of sole 20 with a channel outlet 41 near converging point 42 of the fiberglass sole 20. This construction allows the water which has entered the channel 30 to be shot in an arc 43 as shown (see Fig. 4).
  • sole 22 could be built virtually up over the heel and toe encasing portion of the whole boot 10 and wings 50 (Figs. 3) which are attached directly to this rigid sole for aerodynamic stability and even to provide a slight "lift" for the skier.

Claims (10)

  1. Une chaussure de ski nautique à chausser sur le pied d'un skieur pour skier sur une masse d'eau, comprenant
       une semelle (20) présentant une surface supérieure conçue pour supporter le pied du Skieur, une surface inférieure qui est au contact de la masse d'eau, ladite semelle présentant une longueur qui n'est pas sensiblement plus grande que celle de la surface supérieure conçue pour recevoir le pied du skieur;
       une partie de tige (10) attachée fixement à ladite semelle; et
       un canal d'eau (30) découpé sensiblement dans la longueur de la semelle.
  2. La chaussure conforme à la revendication 1, dans laquelle la semelle comprend une partie frontale incurvée vers le haut et une partie de talon innurvée vers le haut.
  3. La chaussure conforme à la revendication 1 ou 2, dans laquelle la partie de semelle est réalisée en un Produit composite à fibres de verre.
  4. La chaussure conforme à la revendication 1, dans laquelle la partie de tige est dimensionnée et conformée de manière à recouvrir sensiblement le pied du skieur.
  5. La chaussure conforme à la revendication 2, dans laquelle la partie frontale est incurvée vers le haut avec un degré d'incurvation au moins légèrement supérieur à celui de la partie de talon.
  6. La chaussure conforme à l'une quelconque des revendications 1 à 5, dans laquelle la semelle comprend une plaque de pied (25), attachée fixement à la partie de tige suivant sensiblement l'intégralité du périmètre de la partie de tige.
  7. La chaussure conforme à l'une quelconque des revendications 1 à 6, comprenant en outre un moyen d'attache conçu pour s'étendre par-dessus le pied du porteur, sur la partie de tige pour fixer le pied du porteur dans la partie de tige pendant l'utilisation.
  8. La chaussure conforme à l'une quelconque des revendications précédentes, dans laquelle ledit canal d'eau (30) est un canal d'eau en forme de V renversé pour aider à empêcher la chaussure de glisser de manière erratique sur la surface de l'eau.
  9. La chaussure conforme à l'une quelconque des revendications précédentes, dans laquelle à la partie arrière de la sous-face de la semelle en fibre de verre, se trouve une protubérance en forme d'oeuf qui disperse l'eau ayant traversé le canal.
  10. La chaussure conforme à l'une quelconque des revendications précédentes, dans laquelle, en plus du canal d'eau, des trous de pression percés dans la semelle suivant un angle suffisant pour déboucher dans le canal d'eau, servent d'orifices de sortie pour l'eau qui entre dans le canal.
