Balance board

Abstract

A balancing board is disclosed with a base and an elongated deck including a top surface; longitudinal and central lateral axes; and a bottom surface, which includes at the central lateral axis a center post mounting mechanism. The base's bottom side rests on a support surface. The base's top side has a top surface and is rotatable with respect to the bottom side at a rotational bearing. A center post is fixed at its bottom end to and extends upwards from the base's top surface, and has at its top end a pair of roller posts extending laterally and horizontally from the center post at opposing sides. Each roller post rotationally mounts a roller, extended downwardly from the roller post, below the center post's top end. The center post mounting mechanism engages with and aligns each roller with the central lateral axis on opposing sides of the longitudinal axis.

(8) FIGS. 1-4 illustrate a balancing board 10 for use by a user 20 on a horizontal support surface 15 (such as a floor or ground surface). The balancing board 10 comprises an elongated deck 30 having a top surface 39, a bottom surface 31, a longitudinal axis L.sub.1, and a central lateral axis L.sub.2. The elongated deck 30 may be made from Baltic birch wood or any other material with similar mechanical properties. In the preferred embodiment, the top surface 39 of the elongated deck 30 further includes a non-slip texture 140 (FIGS. 1-3). The non-slip texture 140 may be included on the top surface 39 of the elongated deck 30 through application of skateboard grip tape such as that produced by Mob Grip, or any other mechanically similar material. The bottom surface 31 includes at the central lateral axis L.sub.2 a center post mounting mechanism 40 (FIG. 2). In the preferred embodiment, the elongated deck 30 also includes two handle indentations 200 (FIG. 2) in the bottom surface 31 thereof at opposing ends 35 (FIG. 2) thereof.

(9) The balancing board 10 further comprises a base 50 (FIGS. 1-2, 4) having a bottom side 52 (FIGS. 1, 2-3) and a top side 58 (FIGS. 1-3). The base 50 may be constructed from polyethylene, polypropylene, or any other mechanically similar material or combination of materials. The bottom side 52 has a bottom surface 51 (FIGS. 2-3) adapted for resting on the horizontal support surface 15. In the preferred embodiment, the bottom surface 51 of the bottom side 52 further includes at least one high-traction foot 100 (FIG. 2-3) for frictionally engaging the support surface 15. The top side 58 has a top surface 59 (FIGS. 2-4). The top side 58 is rotatable with respect to the bottom side 52 at a rotational bearing 60 (FIGS. 2-3). The rotational bearing 60 may be a ball bearing or any other sort of bearing or pivot that allows the top side 58 and bottom side 52 to mutually spin. In the preferred embodiment, the base 50 further comprises a bottom plate 53 (FIGS. 2-3) having the bottom side 52, and a top plate 57 (FIGS. 2-3) having the top side 58. In this embodiment, the rotational bearing 60 is fixed between the bottom plate 53 and the top plate 57 and allows for the top plate 57 to rotate with respect to the bottom plate 53.

(10) The balancing board 10 further comprises a resilient center post 70 (FIGS. 1-4) fixed at a bottom end 72 (FIGS. 2-4) thereof to the top surface 59 of the base 50 and extending upwardly therefrom. The center post 70 may be constructed from polyurethane or any other mechanically similar material that is resilient. The center post 70 has at a top end 78 (FIGS. 2-4) a pair of roller posts 80 (FIGS. 2-3), each extending laterally and horizontally therefrom at opposing sides 75 (FIG. 4) thereof. The roller posts 80 may be constructed from steel or any other mechanically similar material. In the preferred embodiment, the pair of roller posts 80 are integrally formed from a single metal rod 110 (FIG. 3) that traverses a roller post aperture 120 (FIG. 3), which extends laterally through the center post 70 proximate the top end 78 thereof. In practice, the metal rod 110 may be manufactured from any material of sufficient strength to and possessing all the other mechanical characteristics necessary to maintain the structural integrity and full function of the balancing board 10.

(11) A pair of cylindrical rollers 90 (FIGS. 2-4) is each rotationally mounted on one of the roller posts 80 and extends downwardly therefrom lower than the top end 78 of the center post 70. The center post mounting mechanism 40 of the elongated deck 30 engages with the rollers 90, such that each roller 90 is aligned with the central lateral axis L.sub.2 of the elongated deck 30 on opposing sides of the longitudinal axis L.sub.1 of the elongated deck 30. Each roller post 80 further preferably includes a roller stop 130 (FIGS. 2-3) proximate a distal end 85 (FIGS. 2-4) of the roller post 80 to maintain the roller 90 on the roller post 80. Preferably, the center post mounting mechanism 40 includes a pair of U-bolts 45 (FIGS. 2-4), each fixed with the elongated deck 30 at the bottom surface 31 thereof. Each of the U-bolts 45 straddles the central lateral axis L.sub.2 of the elongated deck 30 on opposing sides of the longitudinal axis L.sub.1 and on opposing sides of the center post 70. Further, each U-bolt 45 captures one of the rollers 90 between itself and the elongated deck 30.

(12) Also preferably, the balancing board 10 further comprises a pair of tilt brakes 150 (FIG. 4) each fixed with the top surface 59 of the base 50 and having a disengaged position 160 (FIG. 4) that does not inhibit flexing of the center post 70 or yaw or roll of the elongated deck 30, and an engaged position 170 (FIG. 4) that inhibits flexing of the center post and yaw and roll of the elongated deck 30. In this configuration, each tilt brake 150 ideally includes an elongated member 155 (FIG. 4) pivotally fixed with a hinge 180 (FIG. 4) at a lower end 152 (FIG. 4) thereof with the top surface 59 of the base 50 and at an upper end 158 (FIG. 4) with an elongated deck engagement surface 190 (FIG. 4).

(13) In use, the bottom surface 31 of the elongated deck 30 contacts the center post 70 and is captured thereon with the center post mounting mechanism 40, such that the elongated deck 30 is free to move with a predetermined range, such as one to three centimeters, in a lateral plane and in a forward/backward plane, as well as in the directions of roll, pitch, and yaw. The center post 70 flexes (FIG. 5) when the weight of the user 20 on the elongated deck 30 fails to maintain his balance substantially directly above the center post 70, and snaps back to a central upright position when the user 20 shifts his weight to again be balanced substantially directly above the center post 70. With the tilt brakes 150 engages the user 20 does not have to contend with the center post 70 being resilient as the brakes hold the elongated deck above the center post 70 to prevent the center post 70 from flexing. Further, the tilt brakes 150 prevent the user from having to contend with the tendency of the elongated board 30 to move in roll or yaw directions.
