FIELD OF THE INVENTION

The present invention relates to wave riding vehicles with a new watercraft shape and features. The vehicle is primarily intended for use as a bodyboard used for surfing oceanic waves. The invention is applicable to conventional surfboards, kneeboards, skim boards, kiteboards, wake surfing boards and wakeboards. The invention may also be adapted for snow riding.

BACKGROUND OF THE INVENTION

Watercraft boards have a variety of shapes that are in part directed by the use. For example, the shape and size surfboards may be generally segmented into longboards, guns, the evolution, funboards, shortboards, and fish. Each type has a shape that is designed for the type of surf, the type of surfer and the objective of the surfer.

The shape of the wave also affects the selection of the board to best compliment the environmental conditions. Experienced surfers have described waves as closeouts, reformed, mushy crumbles, plunging waves, breakers, and tubing waves, Closeouts are caused by strong offshore winds, and the entire wave essentially breaks at the same time. There is little or no taper or curl to the wave surface and they are very difficult to ride. Mushy or crumble waves are slow rolling and not steep and have a gentle break, The best riding breaking waves are referred to as spilling breakers, plunging breakers and surging breakers. Plunging waves, also known as tubing waves, are caused when a wave transfers from deeper water to shallow water and the wave breaks from the top to the bottom. Reforms waves are found in deeper water.

In view of the different types of waves and surf conditions, as well as different surfing objectives from the surf rider, a number of surfboard designs have been developed. A “fish” design surfboard is considered a short board and has a wide nose and swallow tail. These boards have more volume and less rocker than a typical shortboards and can provide improved performance in weak or “mushy” waves. Longboards are designed for larger surfer and are for large waves or long rolling waves. Shortboards and most body boards are highly maneuverable and can be rapidly accelerated by the surfer to quickly catch a wave. While short surfboards are more difficult to ride and are not always for suitable for larger surf riders, most riders can easily ride a body board.

In contrast with surfboards, conventionally, bodyboards are short and are designed to be engaged by the surf rider's body from the waist to the chest area and are held by the rider on opposite sides of the nose. Some riders move to a knelling position on the board as the ride begins. Referring now to FIG. 1, a conventional prior art board 100 has a length from rear to nose of approximately 40 to 45 inches and width of approximately 20 to 25 inches. The sides of the conventional board extend from the rear to the nose and are generally parallel or a gentle convex curve from the rear end to the beginning of the nose section. The upper sides may be gripped by the surf rider, may be pulled to assist with the control the direction of the board. Bodyboards typically have a have a nose that has a bullet shape, or a rounded shape that terminate in a flat tip as shown in FIG. 1. The tail 104 of a body board 101 is referred to as a bat tail. Referring now to FIG. 2, the body board 200 depicted has a crescent tail 202. Crescent tails generally form a wide U shape, which conforms to the waist of the user and puts more of users body in contact with the water's surface. This design offers more control and is suited to both drop-knee riders and prone riders. A crescent tail allows user to easily position their hips on the back of the board to catch waves and are comfortable to paddle. Crescent shapes are also favored because they allow the users to engage the rail edge while riding the face of a wave. In this regard, a surf rider may place his or her his hip in the “tail peg” 140 or back corner of the board which displaces water from the wave face thereby allowing the surfer to track or trim across the face. Generally, the crescent tail is popular feature as user-friendly in terms of maneuverability and comfort.

A second tail design for body boards, as depicted in FIG. 1 is referred to as a bat tail, and as the name suggests, resembles the shape of a bat. This shape is designed for heavier riders or for riding smaller waves. It produces more buoyancy and lift towards the back of the board, allowing more speed and maneuverability. The center extension in the rear provides for this increased buoyancy. Some riders report that the bat tail design assist exiting moves and generally offers a smoother ride through turns. However, when riding large concave and steep wave face shapes, the design may lose some of the high-line holding power.

FIGS. 3A-I, are sectional views of surf riding boards. The side edges of both body boards and surfboards are referred to as the rails, which run from the rear tail to the front nose of the board and connect the top surface to the bottom surface As used herein, a chine refers to the change in angle in the cross section of the surfboard's surface. Fuller rails carry more foam which increases the resistance to sinking and stalling when leaned on edge. Thinner, tapered rails carry less foam, making them easier to sink and lean on edge. The harder the edge, the cleaner the water breaks away and releases from the board, which contributes to speed and looseness. Hard rails penetrate the water poorly at high speeds and resist being leaned on edge. Softer rails, those characterized by a smooth gradual transition from a first planar surface to a second planar surface or rounded edges, provide a smoother, more forgiving response than hard rails. the water tends to bend around their subtle curve rather than breaking away. When riding bigger waves, a softer rail is recommended. Referring now to FIG. 3A, the edge 305 of transition on a rail is referred to as the chine. For body boards, there are two common rail designs, referred to as the 60/40 as depicted in FIG. 3B and the 50/50 as depicted in FIG. 3A. These ratios relate to how much of the chine is at the top and how much of the remaining rail is at the bottom.

A 60/40 rail means that 40% of the chine connects to the deck whereas 60% of the rail is in direct contact with the water. This style of rail is best for maintaining control on bigger, more powerful waves.

50/50 rails are equally divided from the top surface to the bottom surface and offer more speed. The 50/50 design allows an easier disconnect from the wave face. Some signature boards designed by professional riders also have rails with slightly different ratios, such as 70/30 or 55/45 or any ratio that they prefer to achieve the desired balance of speed, stability turning, and buoyancy. With respect to both surfboards, a narrow tail allows a reader to release from moves more easily, as it is less buoyant, whereas a wider tail offers more stability.

FIG. 3F depicts a hard chine 315 in an 80/20 ratio, as further discussed below. FIG. 3G depicts a soft chine design. FIG. 3H depicts a further rail design referred to aa tucked under edge. This design allows for clean water release characterized by a hard rail with the penetration and holding power of a softer rail. Hard rail edges are utilized in the tail area of a board for improved release. Since body boards typically are not provided with fins, grooves or channels are provided on the bottom surface to help control the tracking of the board. FIG. 3I depicts a double chine 321 rail that utilizes an additional ridge or edge that improves surf riders ability to control the bite and release points of a rail. Many boards use a combination of rail configurations.

The other parts of prior art body boards include the core, which typically is comprised of polyethylene (PE), polypropylene (PP), or extruded polystyrene (EPS). The shape of the core dictate of overall shape of the board. Boards may have a harder smooth and slick surface on the bottom that improves speed. As mentioned above since body boards do not have fins, the tail area may be altered to help stabilize the board. Some board have a tail area that features two or three channels which increase the board's adherence to the face of the wave, turn increase stability. Hoverer body boards with a large tail width are more difficult to control and make maneuvers harder to pull.

A wide variety of materials may be used to create the core of the board including but not limited to Expanded Polystyrene foam (EPS), polyurethane foam and Styrofoam. The bottom surface may be glassed with polyester resin or provided with a layer of HDPE. The top surface is typically covered with a layer or film of a polyurethane or rubber. While the described embodiment is direct to body boards, the invention may be used for kneeboards, skim boards, kiteboards, wakeboards, and sleds or toboggans.

Bodyboards typically have a flexible cushioned top surface that has rougher surface to improve comfort and to provide a surface that allows for improved frictional engagement of the rider.

BRIEF SUMMARY OF THE INVENTION

The present invention is directed to a novel shaped body board that allows for quick turning maneuvers. A first embodiment is generally directed to a modified diamond-shaped or kite-shaped body wherein the side rails extend from the rear tail outward from a central axis to a side lateral section and then extend back toward the central axis to the nose section. The lateral section is comprised of parallel rails. A second embodiment is truncated kite-shaped or truncated diamond shape body that is characterized by rails extend from the rear tail outward from a central axis and ten and then back toward the central axis to the nose section. In a further embodiment, a raised hump or ridge is provided across the top surface of the board, positioned about two thirds the distance from the tail to the nose that is designed to provide a structure to engage the upper chest area of a rider and impede the rider from sliding forward on the board and, at the same time, providing additional buoyancy.

As disclosed, the shape of the boards are a modified diamond shaped or modified kite shaped. The width of the tail section from rail to rail is smaller than the prior art boards and they may be flat, crescent, or batwing. The front of the board may be flat or bullet-nosed. Proving a relatively narrow tail may compromise flotation at the rear end and make tricks that require knee work at the rear end more difficult to execute. However, the narrow tail as disclosed will improve maneuverability and allow turns to be executed more readily without materially compromising the buoyancy of the device.
