DETAILED DESCRIPTION OF THE INVENTION

(18) This invention resides in balance boards and, in particular, versatile balance boards that are more physically challenging than existing devices. In some embodiments, balance boards according to the invention are modular, facilitating customization to particular sports or exercise regimes.

(19) In preferred embodiments, the invention comprises an elongated board or deck having upper and lower surfaces, and wherein the lower surface includes a lengthwise groove to receive a separate ground-contacting element. As described in further detail below, the ground-contacting element may be a ball of different sizes, a front-to-back rolling pin, or an insert with rollers or skateboard trucks.

(20) The deck may be constructed of any material capable of withstanding the weight of a heavy adult without breaking. Thus, the deck may be constructed from applicable plastics, various woods, metals such as aluminum, and/or composite materials such as carbon fiber. In preferred embodiments, the deck is of laminated construction, with bonded layers of wood or other materials to increase strength. It is acceptable that the decks flexes somewhat so long as it doesn't break under normal use.

(21) The dimensions of the deck are preferably such that a user 16 may stand with feet separated; for example, as depicted in FIG. 1. Thus, the length of the deck may be in the range of 24 to 36 inches, with the width of the board being on the order of 6 to 24 inches. The thickness of the deck should be in the range of to 3 inches to enable a groove to be formed in the lower surface, whether during molding or machining after fabrication.

(22) The upper surface of the deck 10 may be flat, as shown in FIGS. 1-9, or one or more ends may be contoured. For example, as shown in FIGS. 10-13, the ends of the deck 10 may be curved upwardly in keeping with more traditional skateboard designs. The ends and edges of the deck may be rounded to favor intended use over imbalance situations, and the upper surface may further be textured, or may include grip tape to enhance friction.

(23) FIG. 1 is a view of one ball-and-groove embodiment constructed in accordance with the invention. The use of a separate ball 14 increases the difficulty of balancing on the board, while better simulating a board-type sport such as surfing, snowboarding, skateboarding, and a variety of other sports. In this particular embodiment, the groove 12 is in a form or shape of a partial cylinder with spherical ends, and the radius of ball corresponds to the curvature of the walls and ends of the groove. The ball in this case (as well as other components described herein) is preferably constructed of a suitable hard plastic such as polyethylene. The ball may be hollow or solid and, where the radius of the ball matches the curvature of the groove, the radius may be in the range of to 8 inches.

(24) As shown, a portion of the ball is received by the groove, with the lower portion making ground contact. A user stands on the upper surface of the deck while the board is on top of the ball, making it difficult for a user to stand on the board without touching the ground and without assistance. An advanced use of the board may include moving the ball from one end of the board to another without touching the ground and without assistance. Another use of the ball may include rotating an end of the board to the other end without touching the ground and without assistance.

(25) FIGS. 2 through 4 show different views according to an embodiment of FIG. 1. FIG. 5 is a cross sectional view taken on the line of 5-5 in FIG. 2, and FIG. 6 is a cross sectional view taken on the line of 6-6 in FIG. 5. These views show how the ball 14 fits into the groove 12.

(26) FIGS. 7 through 9 show movements of the board 10 and the ball 14 relative to each other. FIGS. 7 and 8 shows the board 10 tilting at different angles with the ball 14 as a pivot. FIG. 8 shows possible positions and movements of the ball 14 along the groove 12 of the board 10.

(27) Note that while the ball 14 typically rolls in groove 12 without sliding, slipping and sliding of the ball is not precluded by the invention, as both the outer surface of the ball and inner surface of the groove are generally smooth. Thus, depending upon the movements of the user, the ball may roll and/or slide within groove 12.

(28) The size of the ball and/or size of the groove may vary to increase or decrease the difficulty of riding the board. Changing the ball and/or groove would change also the rider's experience. FIG. 10, for example, is a bottom side view of an embodiment of the invention using a smaller ball 20 than the one shown in previous figures. In this case the ball may have a diameter in the range of to 8 inches.

(29) The groove 22 may be the same as the one shown in previous figures, in which case the curvature of the sidewall 24 would not match the radius of ball 20. Alternatively, the curvature of the sidewall may correspond to the radius of the radius of a smaller ball, in which case it may be advantageous to provide a flattened area between the inner curvature of the sidewalls 24, enabling the smaller ball to roll from side to side as well as forward and back. As mentioned, the ends 28, 30 of the deck 32 may be configured for a flat or curved upper surface.

(30) FIG. 11 illustrates a further embodiment wherein the ground-contacting element is a pin 40 that moves substantially forward and back as the user shifts their weight on the upper surface of the deck. In this embodiment, groove 42 may be the same as the groove shown in FIG. 10, or it may have a different shape, including the one shown in previous Figures to better correspond to the design of the pin. The pin 40 may have a central, cylindrical section 44 that rides within the groove 42, with opposing bulbous ends 46, 48 with necked-down regions 50, 52 that ride on side edges 54, 56. As with the ground-contact balls, the pin 40 may be made of any suitably durable material such as part plastic or hard rubber. While the pin 40 will largely maintain front-to-back tilting during use, a moderate degree of twisting is also possible depending upon user movement.

(31) In addition to ground-contacting elements such as balls and pins that contact that move or ride on portions of the groove directly, the invention also contemplates the use of inserts received by the groove that provide other types of ground-contacting elements. The inserts disclosed herein may be held in position with and appropriate mechanism, such as hook-and-loop fasteners (not shown), magnets (not shown) or some combination thereof. The insert may have one or more finger holes and/or tabs or loops to assist with removal. As a further alternative, through bolts that extend through the insert and deck may be used.

(32) As a first example, FIG. 12 illustrates an insert 60 that provides front and back stationary rollers 62, 64. FIG. 12A shows the insert 60 being installed in groove 66, and FIG. 12B shows the insert 60 fully installed. Once installed, the rollers 62, 64 may be equidistant to their respective ends, facilitating symmetrical front/back/side usage, or the distances may be different for a different user experience. Like the decks themselves, inserts disclosed herein may be made from any suitable rigid or semi-rigid material such as hard plastic, wood, etc., without or without a laminated construction.

(33) FIG. 13A depicts yet a different insert-based embodiment of the invention, in this case a panel 70 providing skateboard trucks and wheels 72, 74. FIG. 13A shows the insert 70 being installed in groove 76, and FIG. 13B shows the insert 70 fully installed. The insert may be held in position with and appropriate mechanism, such as hook-and-loop fasteners (not shown), magnets (not shown) or through bolts (not shown). Once installed, the trucks/wheels are preferably equidistant to their respective ends, and the ends of the deck preferably curve upwardly giving the user the fell and performance of a conventional skateboard. But unlike conventional skateboards, the insert 70 may be removed and replaced with a different insert, or a pin or a ball, as the case may be.

(34) In addition to rolling wheels, there are stationary skateboard trucks that allow the user to practice skateboard tricks without worrying about the wheels rolling. FIG. 14A illustrates such an embodiment of the invention having stationary skateboard trucks during installation of the insert, and FIG. 14B shows the embodiment of FIG. 14A with the insert installed.
