60 f4 f2 6 @QQ/iff Mica/af 3,025,539 WATER SKI DEVICE Kent R. Kincaid, 1009 W. Holly St. Walnut Creek, Calif. Filed Mar. 21, 1958, Ser. No. 722,898 1 Claim. (Cl. 9310) This invention relates to sports equipment and, more specifically, the invention pertains to equipment especially designed for water sports.
One of the primary objects of the invention is to provide a new water ski including means for creating a fountain effect.
Another object of this invention is to provide in a water ski means for the stabilization thereof.
A further object of this invention is to provide a water ski with means in the nature of a keel whereby the user may execute maneuvers with a greater degree of accuracy than may be accomplished with water skis heretofore known in the art.
This invention contemplates, as a still further object thereof, the provision of a water ski of the type generally referred to supra, the water ski being non-complex in construction and assembly, inexpensive to manufacture, and durable in use.
Other and further objects and advantages of this invention will become more apparent from a consideration of the following specification when read in conjunction with the annexed drawing, in which:
FIGURE 1 is a longitudinal cross-sectional view of a water ski equipped with fountain and stabilizing means constructed in accordance with this invention, FIGURE l being taken substantially on the horizontal plane of line 1i of FIGURE 2, looking in the direction of the arrows;
FIGURE 2 is a bottom plan view of a water ski equipped with the fountain and stabilizing means illustrated in FIGURE 1;
FIGURE 3 is a transverse detail cross-sectional view taken substantially on the vertical plane of line 3-3 of FIGURE l, looking in the direction of the arrows;
FIGURE 4 illustrates a water ski equipped with fountain and stabilizing means constructed in accordance with a second embodiment of this invention;
FIGURE 5 is a longitudinal cross-sectional view of the fountain and stabilizing means illustrated in FIGURE 4, FIGURE 5 being taken substantially on the horizontal plane of line 5-5 of FIGURE 4, looking in the direction of the arrows; and,
FIGURE 6 is a transverse cross-sectional view taken substantially on the vertical plane of line 6--6 of FIG- URE 5, looking in the direction of the arrows.
Referring now more specically to the drawing, reference numeral 10 designates, in general, a water ski constructed in accordance with one embodiment of this invention. The ski It) is seen to comprise the conventional elongated substantially rectangular runner 12 to the rear end of which is secured fountain producing and ski stabilizing means I4 to which the present invention is addressed.
The fountain producing and stabilizing means includes an elongated substantially rectangular at top wall 16 which terminates in a rearwardly extending, integrally formed and upwardly curved arcuate extension 18. From the opposed longitudinally extending sides of the top wall 16 depend, respectively, a pair of laterally spaced and substantially parallel rectangular side walls 20, 22 which serve the dual functions of a keel and stabilizing means. The side walls, 2d, 22 extend rearwardly to form integrally connected elongated substantially rectangular side wall extensions 24, 26, respectively, which also depend from the opposed longitudinally extending marginal edges of the top wall 18. As is seen in FIGURE l of the States Patent O f asians Patented Mar. 20, l 962 drawing, the lower ends of the side walls 24, 26 are arcuate in configuration and taper in width from their inner ends to their respective outer ends. An elongated substantially rectangular bottom wall 23 extends across and is preferably integrally formed with the lower ends of the side wall extensions 24, 26.
It is thus seen that the top wall 18, the side wall extensions Zl, 26 and the bottom wall 28 form an elongated substantially hollow forwardly opening compartment 30 having a restricted discharge opening 32 longitudinally spaced from the rear end of the ski. A plurality of screws 34 extend through the top wall I6 to provide means for securing the fountain producing and stabilizing device 14 to the ski runner 12 adjacent the rear end thereof.
From the foregoing description of the fountain producing and stabilizing device 14 it is manifest that the side walls 2t), 22 function in the nature of keels to lend to a user a greater degree of control in skiing in a straight line or in executing a curving or turning maneuver. Simultaneously, water entering the forwardly opening cornpartment 30 is forced through the restricted discharge opening 32 at a relatively high velocity to form a fountain 36 which is not only spectacular but pleasing to the observer.
FIGURES 4 to 6, inclusive, illustrate a second embodiment of this invention wherein reference numeral 4l) denotes, in general, a ski constructed in accordance with the present invention, the ski 40 including a conventional ski runner 42.
The fountain producing and stabilizing means is generally designated at 44 and includes an elongated substantially rectangular plate 46 having longitudinally extending, arcuately shaped, depending, laterally spaced and confronting side walls 48, Sli.
A first elongated open-ended tubular conduit 52 is welded at 54 to the plate 46 and is also welded at 56 to the side wall 48. The conduit 52 terminates in a rearward extension 58 having an upwardly curving arcuate configuration (see FIGURES 5 and 6). The water inlet end is designated at 60 and the fountain discharge end is denoted at 62.
A second elongated open-ended tubular conduit 64 is welded at 66 to the plate 46 and is welded at 68 to the side wall 48. The water inlet end for the second tubular member 64 is designated at 72, and the fountain discharge end thereof is denoted at 74.
The combined fountain producing and stabilizing device 44 is secured to the runner 42 by means of a plurality of screws 76 which extend transversely through the plate 46 and penetrate the ruimer 42 adjacent the rear end thereof.
It should now be self evident that the tubular members 52 and 64 at each side of the runner 42 act as keels to provide the user with a greater degree of control and stabiilty when skiing in a straight line or when elfecting a curve or turning movement. Simultaneously, water will pass into the tubular conduits 52, 64 through their respective inlet openings 60, 72 and will be discharged through the outlet or discharge openings 62, 74, longitudinally spaced rearwardly of the rear end of the ski, and with suiiicient force to produce a pair of fountains (not shown) each somewhat similar to the fountain 36.
In setting forth both embodiments of this invention, the fountain producing and stabilizing means 14 and 44 have been described in association with a water ski. It iS to be understood, however, that these means may be manufactured, sold and employed as attachment units separate and apart from the ski, per se.
Having described and illustrated in detail two embodiments of this invention, it will be understood that the same o u are offered merely by way of example, and that this invention is to be limited only by the scope of the appended claim.
What is claimed is: A water ski comprising a-at board having a rear end, a -top wall secured to the undersurface of the board, depending side walls on and extending along said top Wall to the rear end of the board, and nozzle means Secured to and extending rearwardly from said top wall and said side walls, said nozzle means being rearwardly and upwardly curved, said nozzle means comprising tubular nozzles secured to and extending along said side Walls.
