1 Claim. (Cl. 9-21) This invention relates to surfboards, water skis, and other supporting devices for supporting persons while being towed, particularly by motor boats and the like, and in particular a saucer-shaped disc having spaced foot retaining sockets therein and also having a bracket for holding a towing rope at one side.

The purpose of this invention is to provide a device, such as a surfboard, that may readily be turned around with an occupant riding thereon and that is adapted to be used for jumping on the surface of the water as it is being towed.

Various types of water sleds, skis, and surfboards have been provided, particularly for supporting occupants while being towed with motor boats and the like and wherein such devices are successfully operated for forward travel it is not possible for the rider to make the complete turn or cause the devices to move upwardly above the surface of the water. With this thought in mind this invention contemplates a circular disc having a continuously upwardly flared rim with spaced foot holding elements on the upper inner surface and with a readily releasable bracket for holding a towing rope, mounted on the rim.

The object of this invention is, therefore, to provide a surf or water surface riding device that is adapted to be rotated on the surface of the water as it is being towed.

Another object of the invention is to provide a device for riding on the surface of the water that is adapted to be used with the wearing apparel of a rider remaining dry.

A further object of the invention is to provide an improved surf riding device that is adapted to rotate on the surface of the water and that is of a simple and economical construction.

With these and other objects and advantages in View the invention embodies a disc formed of plywood or other suitable material having a continuous upwardly flared peripheral flange or rim with spaced foot holding elements mounted on the upper surface and positioned within the rim, and with a bracket having a slot therethrough mounted on the rim and positioned on a line extended between the foot holding elements whereby a rope may be attached to the disc until a rider is positioned thereon.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is a plan view of the aqua disc.

Figure 2 is a longitud nal section through the disc taken on line 2-2 of Fig. 1.

Figure 3 is a detail showing a section taken on line 33 of Fig. 1, illustrating the mounting of the foot holding elements on the disc.

Figure 4 is a cross section taken on line 44 of Fig. 3 also showing the mounting of the foot holding elements on the disc.

Figure 5 is a plan view of the rope holding bracket positioned on the rim of the disc.

Figure 6 is a longitudinal section through the bracket taken on line 66 of Fig. 5. I

Figure 7 is a cross section through the rope holding bracket being taken on line 7-7 of Fig. 5.

Figure 8 is a detail showing a section taken on line 8-8 of Fig. 1 illustrating the method of securing the upwardly inclined rim to the fiat portion of the disc.

Figure 9 is a section similar to that shown in Fig. 8 illustrating a modification wherein the disc is formed of moulded plywood or the like.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved aqua disc of this invention includes a flat circular base 10 having a continuous upwardly inclined rim 11 with foot holding sockets 12 and 13 on the section 10, and with a bracket 114 mounted on the rim.

In the design as illustrated in Figs. 1 and 2 the device is formed with plywood and a circular sheet or panel 10 is secured by a ring 15 to arcuate sections 16 which form the flange or rim 11 and the sections 16 are spliced with splice plates 17. The ring 15 is secured to the panel 10 and sections 16 with water proof glue, fasteners or screws, as indicated by the numeral 18 and the splice plates 17 are secured to the ends of the sections 16 by similar means.

In a design illustrated in Fig. 9 the device is formed with a continuous panel 10 the edge of which is molded to extend upwardly from a continuous flange or rim 20 and this may be formed of plywood, plastic, or other suitable material.

As illustrated in Figs. 3 and 4 the foot holding elements or sockets 12 and 13 are formed with a rubber sheet 21 and the edge of the sheet is secured by screws 22, which extend through a continuous molding strip 23 to the panel 10. The rubber sheet is formed to extend upwardly, as shown in Figs. 3 and 4 and the upper parts are provided with openings 24 through which the feet are inserted in the sockets. Although it is suggested that the sockets be formed of rubber, it will be understood that they may be formed of other suitable material.

The rope holding bracket 14 is provided with a base having screw openings 25 therein and the bracket is secured to the rim or flange with screws extended through said openings. The outer ends of the openings may be countersunk whereby they are adapted to receive flat head screws. Lugs 26 and 27 extend upwardly from the base 14, providing a rope receiving slot 28 and the surfaces of the lugs at the center of the base are inclined providing projecting upper ends whereby a stick or rod, to which the end of a rope is secured may be placed below the projecting ends with the rope extended through the slot 28. The end surfaces 29 of the lugs extend from a point 30, substantially at the center of the base of the bracket, outwardly to points 31 providing projecting ends whereby a stick or rod to which the ends of a rope is secured is adapted to be retained in the brackets with the rope extended through the slot 28.

Although the disc is described as being formed of plywood it will be understood that it may be made of plastic or other suitable material.

With this device a rider may step upon the disc from a dock or from another boat with a rope from a motor boat or the like secured in the bracket and with the feet of the rider positioned in the sockets 12 and 13 he may withdraw the end of the rope from the bracket as the disc is started by the towing boat and as the boat gains speed the rider may balance himself in an upright position. By this means a person may ride upon the surface of the water, similar to the action of a surfboard and the disc may be turned making a complete revolution by rotating the body and passing the rope from one hand to the other. With the feet secured to the disc by the sockets the lower the slack in the rope is taken up by the boat starting away.
