Abstract
An aquatic device for carrying a rider, includes a buoyant mat having handles and towing attachments. The mat has inflatable air channels which are formed to permit the mat to arch over the water, carrying the rider when towed at proper speed. One or more air channels extend transversely to the major axis along a forward portion of the mat. A rear portion has air channels which radiate out towards a peripheral air channel. The towing attachments are mounted to the forward edge of the mat.
Description
- For some time, water sports enthusiasts have ridden on inner tubes towed by pleasure water craft. The inner tube has handgrips which permit the rider to grasp the tube and steer the tube while it is being towed. The tube bounces on the wake of the towing craft and on waves. When the tube is towed at higher speeds, the impact of the wave and wake bounces is great. Accordingly, it would be desirable to provide a device which could be ridden at high speeds and readily controllable by the user and comfortable to use.
- An aquatic device for carrying a rider includes a buoyant mat having handles and towing attachment. The mat has a forward section which lifts off the water in an arch to form a tunnel for air passing through and under a rear section which curves downwardly and rearwardly to a peripheral edge adjacent the water. The rider lays on a top layer surface of the mat grasping the handles with his feet extending rearwardly over the top layer. The mat has a plurality of air chambers which are inflated with air to provide buoyancy. The channels of the forward section extend transversely to resist folding when being towed. A peripheral skirt portion rides on the water.
- The foregoing and other objects and advantages of the present invention will become readily apparent to those skilled in the art upon studying the following detailed description, when considered in connection with the accompanying drawings, in which:
- FIG. 1 is a perspective view of the aquatic device shown in use as it is towed;
- FIG. 2 is a top view of the device in accordance with the invention; and
- FIG. 3 is a side view of the aquatic device shown in its position in use in accordance with the invention;.
- As shown in FIG. 1, a novel
aquatic sport device 10 includes abuoyant mat 12, adapted to be towed across the surface of a body of water by a boat (not shown). The periphery of the mat lays flat on the water when at rest (FIG. 3). However, the rear channels are formed to make a bubble centered at the joinder of the frontal portion and the rear portion. The bubble slopes downwardly to the peripheral portion. Arider 14 lays face down on a top surface of themat 12 and grasps a pair of hand holds 16. When towed, themat 12 forms a scoop and lifts off the water. The center of the mat arches to approximately 2 to 2½ feet when the mat is towed behind the boat at speeds of 25 to 30 miles per hour. - In the preferred embodiment, the
mat 12 is formed of a series of interconnected air chambers which are inflated with air in the same manner as an inflatable raft. Interconnecting air passages extend between the chambers to permit inflation of all of the chambers. However, it is within the contemplation of the invention to use other materials, such as closed celled foam, which provide sufficient buoyancy and flexibility. As shown in FIG. 2, The mat includes askirt portion 18, a rectangularforward portion 20, a semi-ellipticalrear portion 22. The mat has an outerperipheral edge 19. The mat is symmetrical about a major axis “a”. - The
mat 12 is formed by doubling a sheet of PVC about thefront edge 24 to form atop surface layer 26 and a bottom surface layer 28 and seaming the layers as known in the art to form inflatable air chambers. When inflated, the air chambers are tubular with a generally circular cross-section. One ormore inlets 30 having threaded nipples are mounted between the layers at the peripheral edge for attachment to an inflation device (not shown). Theforward portion 20 includes fourair chambers 33 extending transversely between theskirt portion 18. Thechambers 33 extend transversely to resist the force of the tow rope to fold the mat together about the major axis when being towed. The first two chambers of theforward portion 20 may be reinforced by doubling the material for both the upper and bottom surface layers. Theforward portion 20 is approximately 70 inches wide and 28 inches deep. - The
rear portion 22 has a plurality ofair chambers 34 which radiate from acenter seam line 36 extending perpendicularly from theforward portion 20, as shown in FIG. 2.Seam lines 38 extend from the curvedperipheral skirt portion 18 toward the center of theforward portion 20 to form thechambers 34. - As shown in FIGS. 1 and 3, the mat has an inner seam on the bottom layer28 to form a
bend line 44 for theperipheral skirt portion 18. Thebend line 44 extends from both sides of the front edge and is spaced inwardly from theperipheral edge 19. Thebend line 44 permits the periphery of the mat to bend inwardly to a nearly vertical alignment when the mat is being towed to ride on the water. - One or more pairs of
handles 16 with a mounting base are mounted to thetop surface layer 26 of theforward portion 20. The pairs ofhandles 16 are spaced apart approximately 48 inches. The handles extend upwardly for gripping by the rider and are angled at approximately 45° to the front edge to provide hand holds for the rider. - As shown in FIG. 1, a pair of
towing attachments 50 are mounted on thefront edge 24 adjacent eachhandle 16. The attachment may be of any suitable type. In the preferred embodiment, a reinforcedpatch piece 52 with a center aperture is folded over adowel rod 54 of metal or composite and is affixed to the mat at the forward edge. The patch piece is seamed to hold the rod in position. The aperture provides access to therod 54 for attachment to atow rope 56 which is connected to the boat towing themat 12. The mat can be inserted in a nylon cover which provides a smooth surface and provides flexibility in placement of handles. - To use the
aquatic device 10, therider 14 lays across the top surface layer of the mat grasping the handles. When theaquatic device 10 is towed, air passes over theforward portion 24 above and below the mat to create a pressure differential. The mat acts as an air foil and rises. Themat 12 forms an arc, the top of which is approximately 32 inches from the water surface. Thetransverse tubes 33 resist folding of the mat. Therear portion 22 assumes an elongated semi-domed shape which curves downwardly from the highest portion of theforward portion 20 to theskirt portion 18. Thebend line 44 acts as a live hinge to permit the peripheral portion to easily bend and extend nearly vertically downwardly towards the water to enclose a tunnel over the water. - When the foil is towed at speeds of approximately 25 to 35 miles per hour, the foil will rise and ride on the apparent wind created by the movement of the foil through the air. Pressure differential between the air flowing over the top and bottom of the foil will create lift, forming the dome shape. The rider will be able to “fly” the foil by pushing then pulling the handles to steer and/or lift the foil from the water.
- As will be apparent from the attached claims, these and other variations of the invention are within the scope of the invention which is defined by the attached claims.
