Description

FIELD OF THE INVENTION

The present invention relates to the field of fitness devices. In particular, the field of exercise devices for developing balance and providing stabilization.

BACKGROUND

Exercise balance balls not only assist in fitness development, but can also provide a seating option alternative to traditional desk chairs. When used in place of traditional chairs, balance balls assist in developing a user's balance, stabilization, and body strength, while the user focuses on maintaining a proper seated position. This is especially beneficial for children as the typically inflated ball provides an outlet for idle energy while simultaneously developing their physical health. Furthermore, users with disabilities (e.g., cerebral palsy) may benefit from the added sensory input of an exercise ball over a regular chair. However, due to the spherical design of traditional exercise balls, loss of user balance in any direction while seated on the ball may cause distraction and even lead to potential injury. As such, there is a need for an improved exercise ball design that provides a dedicated support and stabilization structure to increase safety of a user.

FIG. 1-6 depict a collection of views of a fitness device 100, in accordance with one embodiment of the invention. The fitness device 100 generally includes a spheroidal or oblong member 102 and a structured surface 122 located within an aperture 142 of the spheroidal member 102. In the illustrated embodiment, the spheroidal member 102 has a capsule-like shape, wherein the member 102 further includes a cylindrical middle portion 104 extending between a first endcap 106 and a second endcap 108. The endcaps 106 and 108 are approximately hemispherical. In a particular embodiment, the spheroidal member 102 is approximately 32 inches in length and 21 inches in diameter. It should be understood that in alternative embodiments, the spheroidal member 102 may have larger or smaller dimensions to accommodate users of a variety of sizes (e.g., adult-sized).

It should also be understood that in alternative embodiments, the spheroidal member 102 may embodied as other shapes. In one embodiment, the spheroidal member 102 is an ellipsoidal shape. In another embodiment, the spheroidal member 102 is a spherical shape. In yet another embodiment, the spheroidal member 102 has multiple spherical elements (e.g., dumbbell-shaped). In yet another embodiment, the member 102 may have endcaps 106 and 108 that are flat or non-spherical (e.g., cylindrical, hourglass-shaped, or the like).

Due to the spheroidal or oblong shape of the fitness device 100, the fitness device is generally limited to a rolling motion along a surface in only directions approximately perpendicular to a longitudinal, central axis 110 of the spheroidal member 102. By limiting the directions of possible movement of the fitness device 100 along the surface, the potential for accidental injury from a user's spontaneous loss of balance may be reduced when compared to traditional exercise balance balls.

The spheroidal member 102 further includes a hollow, internal cavity 144 and is inflatable. Air may be transferred into the interior cavity 144 of the spheroidal member 102 via a valve 112. The spheroidal member 102 is made of an elastomeric, recoverably deformable material (e.g., polyvinylchloride (PVC)) that is also durable and of a sufficient thickness to prevent air leakage or bursting of the spheroidal member 102 during inflation or use. Due to the inflatable and elastic natures of the spheroidal member 102, the fitness device 100 is generally soft, lightweight, and recoverably deformable under an applied force of a user (e.g., sitting, bouncing, squeezing, rolling, etc.). In an alternative embodiment, the spheroidal member 102 is a solid member and does not include an internal cavity 144, wherein the spheroidal member 102 is made from a solid material (e.g., foam rubber or the like). In another embodiment, the spheroidal member 102 has a textured surface (e.g., studded, ribbed, etc.). For example, as illustrated in FIG. 2C, in one embodiment, the spheroidal member 102 comprises one or more ribs 132 encircling the cylindrical middle portion of the 104. In another embodiment, the spheroidal member 102 is formed of a structural material with a hollow interior, where the structural material is of sufficient rigidity to withstand the weight of the user on its own without collapsing.

The spheroidal member 102 further comprises an aperture 142 positioned on the surface of the member 102. In the illustrated embodiment, the aperture 142 is positioned between the endcaps 106 and 108 at a midpoint along the surface of the member 102. A structured surface 122 is positioned within the aperture 142 of the spheroidal member 102. The structured surface 122 is operatively coupled to the spheroidal member 102 about the edges of the aperture 142. In one embodiment, a tape or heat-seal 140 extends over the joined edges of both the structured surface 122 and the spheroidal member 102 to operatively couple the structured surface 122 to the spheroidal member 102, wherein an air-tight seal is formed over and/or between the joined edges.

In the illustrated embodiment, the structured surface 122 includes a first surface 124, a second surface 126, a first side wall 128, and a second side wall 130 that partially extend into the interior cavity 144 of the spheroidal member 102 to form an externally accessible cavity or compartment 120. The first 124 and second 126 surfaces or portions of the structured surface 122 extend into the interior of the spheroidal member 102 approximately perpendicular to the surface of the spheroidal member 102 from the edges of the aperture 142 toward the central axis 110 of the spheroidal member 102. Said another way, the first 124 and second 126 surfaces extend radially from the surface of the spheroidal member 102 towards the interior cavity 144. The first 124 and second 126 surfaces meet or join together at a shared edge within the interior of the member 102 at an angle of approximately 90° relative to one another. The side walls 128 join the remaining edges of the first 124 and second 126 surfaces to the spheroidal member 102 to form the cavity 120. The edges of the side walls 128 are curved to generally follow the curvature of the spheroidal member 102 where the side walls 128 couple to the surface of the spheroidal member 102.

In a specific embodiment the first 124 and second 126 surfaces of the structured surface 122 each have a length of 6 inches that extends into the interior of the spheroidal member 102 and a width of 10 inches that is coupled along the edge of the aperture 142. It should be understood that the components of the structured surface 122 may be embodied as having alternative dimensions, wherein the structured surface 122 may extend to a greater or lesser extent into the spheroidal member 102. Furthermore, in other embodiments, the first 124 and second 126 surfaces may be dimensioned so as to meet at an angle other than 90° so as to increase or decrease an opening of the formed cavity 120.

The structured surface 122 is made of a substantially rigid material (e.g. plastic) that is able to retain the shape of the cavity 120 even while under the influence of external forces (e.g., from the inflated spheroidal member 102 or from user interaction). In one embodiment, an exterior surface of the structured surface 122 is covered with the same material used to make the spheroidal member 102.

In some embodiments, the structured surface may be an integral part of the spheroidal member, where the portion of the spheroidal member defining the structured surface is structured to form a cavity and is rigid so as to support a user. In this embodiment, the portion of the spheroidal member forming the structured portion, could be formed with walls and structured seams to create the desired shape for the structured surface 120 with proper rigidity.

As illustrated in FIGS. 3-5, the structured surface 122 provides a seat within the cavity 120, wherein the fitness device 100 may be used as a chair by a user 160. The user 160 positions his or her backside within the cavity 120 and sits on the first surface 124 while the user's back is properly supported and oriented by the second surface 126 (as seen in FIG. 5). In one embodiment, at least one of the first surface 124 and second surface 126 are contoured to conform to a user's legs and/or back. The user 160 is partially retained in the seat of the cavity 120 by the side walls 128 of the structured surface 122. The user 160 may place his or her feet on the ground to further support the user 160 on the chair and prevent or control movement of the chair along the surface. In this way, the user 160 is enabled by the fitness device 100 to maintain or safely develop a sense of balance while safely sitting.

The user 160 is further enabled by the fitness device 100 to develop strength (e.g., leg and core) and balance through the active support and tactile feedback received from resisting rolling movement of the device 100 while maintaining a seated position. The user 160 may further receive a stimulating tactile response or sensory feedback from intentional movement of the device 100 along the surface due to the elastic nature of the device materials. For example, the user 160 may bounce in place while seated on the fitness device 100 or safely rock in directions permitted by the shape of the device 100. Alternatively, as illustrated in FIGS. 4 and 5, the user 160 may sit in the cavity 120 of the fitness device 100 while receiving additional support from another user to help maintain and develop balance.

As illustrated in FIG. 6, the structured surface 122 provides a platform or work space. For example, in the illustrated embodiment of FIG. 6, the cavity 120 formed by the structured surface 122 provides a table-like space in which a user (e.g., a child) may play or perform activities while actively supporting themselves with the fitness device 100 while standing or kneeling. In this way, a small child can develop his or her balance through the active support of the fitness device while the cavity 120 partially retains items (e.g., toys, building blocks, notebooks, etc.). In this way, the user 160 may be enabled by the fitness device 100 to develop strength and balance through the active support and tactile feedback received from the fitness device 100.

In alternative embodiments, the aperture 142 of the spheroidal member 102 may be positioned in other locations about the member 102. For example, the aperture 142 may be positioned on one of the endcaps 106, 108. In other embodiments, the spheroidal member 102 may have multiple apertures and/or structured surfaces 122 positioned about the spheroidal member 102. For example, in one embodiment, the fitness device 100 may include two cavities 120 providing back-to-back seats on a single fitness device 100, wherein two users may sit on the fitness device 100.
