Description

TECHNICAL FIELD

The present disclosure relates generally to a core bladder and an assembly including the same.

BACKGROUND

This section provides background information related to the present disclosure and is not necessarily prior art. Inflatables and inflatable exercise devices are generally known, but tend to have the shortcomings that often features making them easily portable often compromise one or more of strength, compactness, and/or usability. Thus, while existing inflatables or inflatable exercise devices perform adequately for their intended purpose, improvements to inflatables are continuously being sought in order to advance the arts.

SUMMARY

This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

One aspect of the disclosure provides a core bladder including a body, a skeletal load-support matrix, and a valve. The body defines a fluid-receiving cavity. The skeletal load-support matrix is disposed within the fluid-receiving cavity. The valve is supported by the body. The valve is configured to permit fluid communication with the fluid-receiving cavity to selectively arrange the body in one of a compact deflated state and an expanded inflated state.

Implementations of the disclosure may include one or more of the following optional features. In some implementations, the body is configured to include a dome portion and a bowl portion. The dome portion includes a curved sidewall and a substantially flat top wall. The bowl portion includes a curved sidewall and a substantially flat bottom wall. A lower edge of the curved sidewall of the dome portion is connected to an upper edge of the curved sidewall of the bowl portion.

In some examples, the skeletal load-support matrix includes a plurality of rib members extending between an inner surface of the substantially flat top wall and an inner surface of the substantially flat bottom wall. The plurality of rib members include a first rib member, a second rib member, and at least one intermediate rib member arranged between the first rib member and the second rib member. A length of one or both of the substantially flat top wall or the substantially flat bottom wall extends at least between the first rib member and the second rib member. A width of one or both of the substantially flat top wall and the substantially flat bottom wall extends at least between a first sidewall of each rib member and a second sidewall of each rib member.

In other examples, the lower edge of the curved sidewall of the dome portion defines a perimeter of the dome portion. The upper edge of the curved sidewall of the bowl portion defines a perimeter of the bowl portion. The perimeter of each of the dome portion and the bowl portion defines a substantially elliptical shape. In some instances, the body is formed of a polyurethane sheet having a thickness of about 0.5 to about 2 mm.

Another aspect of the disclosure provides an exercise assembly. The exercise assembly includes a core bladder and an outer case. The core bladder includes a sealed body supporting a valve that permits fluid communication with a fluid-receiving cavity of the sealed body for selective arrangement of the body in one of a compact deflated state or an expanded inflated state. The outer case is formed by a plurality of panels defining a core bladder receiving cavity that contains the core bladder. The outer case includes a first opening that cooperates with a closure element that provides selective access to the core bladder receiving cavity and a second opening that is sized for permitting access to the valve.

Implementations of the disclosure may include one or more of the following optional features. The core bladder includes a skeletal load-support matrix disposed within the fluid-receiving cavity. The core bladder is configured to include a dome portion and a bowl portion. The dome portion includes a curved sidewall and a substantially flat top wall. The bowl portion includes a curved sidewall and a substantially flat bottom wall. A lower edge of the curved sidewall is connected to an upper edge of the curved sidewall of the bowl portion.

In some examples, the skeletal load-support matrix includes a plurality of rib members extending between and connecting an inner surface of the substantially flat top wall and an inner surface of the substantially flat bottom wall. The plurality of rib members include a first rib member, a second end rib member, and at least one intermediate rib member between the first rib member and the second rib member.

In other examples, the plurality of panels that form the outer case includes a top panel, a bottom panel, and an intermediate panel. The top panel is configured to include a dome-shape when the core bladder is arranged in the expanded inflated state. The bottom panel is configured to include a bowl-shape when the core bladder is arranged in the expanded inflated state. The intermediate ring-shaped panel connects the dome-shaped panel to the bowl-shaped panel. The intermediate ring-shaped panel defines the first opening that provides selective access to the core bladder receiving cavity. One of the dome-shaped panel and the bowl-shaped panel defines the second opening that is sized for permitting access to the valve.

In some instances, the closure element is attached to the intermediate panel and extends over the first opening. The closure element includes a zipper having a body of material supporting cooperating teeth that are selectively joined by a slider. The top panel includes a reinforcement ring circumscribing the second opening.

In some examples, one or both of the top panel and the lower panel includes a frictional, slip-resistant portion. The frictional, slip-resistant portion includes a textured pattern optionally formed by a lightweight denier material having a urethane coating. The lightweight denier material includes ripstop nylon. The urethane coating includes polyurethane or thermoplastic polyurethane. The frictional, slip-resistant portion further includes a silicon gel pattern arranged over the lightweight denier material.

DETAILED DESCRIPTION

The present disclosure relates generally to an assembly (see, e.g., FIGS. 1-2) including an inflatable portion (see, e.g., FIGS. 3-10) removably disposable within an outer casing portion (see, e.g., FIGS. 11-14). In some instances, the assembly may be selectively arranged in: (1) an assembled-and-inflated state (see, e.g., FIG. 2) whereby the inflatable portion, while arranged in an inflated state, is disposed within the outer casing portion such that the assembly may be said to be configured in an expanded state; (2) an assembled-and-deflated state whereby the inflatable portion, while arranged in a deflated state, is disposed within the outer casing portion such that the assembly may be said to be configured in a compacted state; (3) a disassembled-and-separated state (see, e.g., FIG. 3), whereby the inflatable portion, while arranged in an inflated state, may be utilized independently of the outer casing portion; and (4) a disassembled-and-separated state (see, e.g., FIG. 11), whereby the outer casing portion may be laundered independently of the inflatable portion. Embodiments of the present disclosure provide technical solutions to a number of technical problems in the art.

Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure.

With reference to FIGS. 1-2, implementations of the present disclosure relate generally to an assembly, which is shown generally at 10, components thereof, and methods of use. In some instances, the assembly 10 may be utilized as an abdominal core strength training exercise device, which may alternatively be referred to as a “stability board”. As will be described in the following disclosure, the assembly 10 is sized for easy and convenient resizing (i.e., by way deflation or inflation) in order to promote deflated compact storage, inflation for use, disinfection/cleanability, and the like.

Referring to FIG. 1, in some implementations, the assembly 10 includes an inflatable portion 12 and an outer casing portion 14. The inflatable portion 12 includes a valve 16 supported by a body 18 defining a fluid-receiving cavity 20 (see also, e.g., FIGS. 7-8).

With reference to FIGS. 1-2, the outer casing portion 14 includes a body 22 defining cavity 24 (see, e.g., FIG. 1) that is sized for receiving the body 18 of the inflatable portion 12. In some configurations, the body 22 of the outer casing portion 14 may include an opening 26 (see, e.g., FIGS. 12 and 14) that permits insertion or removal of the body 18 of the inflatable portion 12 into or out of the cavity 24 of the body 22 of the outer casing portion 14. In other configurations, the body 22 of the outer casing portion 14 includes an opening 28 (see, e.g., FIGS. 1, 11, and 12) that permits, as seen at FIG. 2, access to the valve 16 of the inflatable portion 12 when the body 18 of the inflatable portion 12 is disposed within the cavity 24 of the body 22 of the outer casing portion 14.

Referring to FIGS. 3-10, exemplary aspects of the inflatable portion 12 are shown. As seen at FIGS. 4 and 6, the body 18 of the inflatable portion 12 generally defines the inflatable portion 12 to include a length L₁₂ (see, e.g., FIGS. 4-6), width W₁₂ (see, e.g., 4, 5, 9), and a height H₁₂ (see, e.g., FIGS. 6, 7, and 9).

When the inflatable portion 12 is arranged in an inflated state, in some implementations and while the dimensions are not critical, the length L₁₂ of the inflatable portion 12 may be approximately equal to 60.0 to 70.0 centimeters (cm). In other implementations, when the inflatable portion 12 is arranged in an inflated state, the width W₁₂ of the inflatable portion 12 may be approximately equal to 30.0 to 50.0 centimeters (cm). In further implementations, when the inflatable portion 12 is arranged in an inflated state, the height H₁₂ of the inflatable portion 12 may be approximately equal to 10.0 to 20.0 centimeters (cm). Accordingly, a ratio of the inflated state length L₁₂ of the inflatable portion 12 to the inflated state width W₁₂ of the inflatable portion 12 may be approximately 1.0:1.6. Furthermore, a ratio of the inflated state length L₁₂ of the inflatable portion 12 to the inflated state height H₁₂ of the inflatable portion 12 may be approximately 1.0:4.6. In other words, in some configurations, when the inflatable portion 12 is arranged in an inflated-and-at-rest orientation with no external forces being applied thereto from surrounding atmosphere A (see, e.g., FIGS. 7-8), the inflatable portion 12 may define a generally rectangular cuboidal shape with curved corners and sides (i.e., as will be described in the following disclosure, the inflatable portion 12 is deliberately structured so as to not form or otherwise provide a spherical shape).

In some implementations, the body 18 is formed from one or more fluid barrier sheets having a thickness T₁₈ (see, e.g., FIG. 8) that prevents a pressurized fluid P (see, e.g., FIG. 8), such as, for example, air or water, to escape from the fluid-receiving cavity 20 to surrounding atmosphere A (see, e.g., FIG. 8). One or more materials may define the one or more fluid barrier sheets; in some examples, a polymer material, such as, for example, a polyurethane material may define the one or more fluid barrier sheets. The thickness T₁₈ of the one or more fluid barrier sheets may be any desirable thickness, ranging from, for example, about 0.05 centimeters (cm) to about 0.2 centimeters (cm), or 0.05 centimeters (cm).

In some configurations, the one or more fluid barrier sheets that form the body 18 of the inflatable portion 12 may include a first fluid barrier sheet, a second fluid barrier sheet, and a third fluid barrier sheet. With reference to FIGS. 3, 4, and 6, the first fluid barrier sheet is configured to form an upper dome portion 18a of the body 18 upon inflation of the inflatable portion 12 with the pressurized fluid P. As seen at FIGS. 3, 5, and 6; the second fluid barrier sheet is configured to form a lower bowl portion 18b of the body 18 upon inflation of the inflatable portion 12 with the pressurized fluid P. Referring to FIGS. 3 and 6, the third fluid barrier sheet is configured to form an intermediate band portion 18c of the body 18 upon inflation of the inflatable portion 12 with the pressurized fluid P.

With reference to FIGS. 3, 6, and 7, the body 18 may include a first sealed flange portion 30 and a second sealed flange portion 32. As seen at FIG. 6, the first sealed flange portion 30 may be formed by a sealed connection of: (1) a lower perimeter 18a_L of the first fluid barrier sheet forming the upper dome portion 18a to (2) an upper perimeter 18c_U of the third fluid barrier sheet forming the intermediate band portion 18c. The second sealed flange portion 32 may be formed by a sealed connection of: (1) an upper perimeter 18b_U of the second fluid barrier sheet forming the lower bowl portion 18b to (2) a lower perimeter 18c_L of the third fluid barrier sheet forming the intermediate band portion 18c.

As described above, the third fluid barrier sheet that forms the intermediate band portion 18c is utilized for connecting the first fluid barrier sheet forming the upper dome portion 18a to the second fluid barrier sheet that forms the lower bowl portion 18b. In some configurations, the intermediate band portion 18c is configured to form a substantially elliptical shape upon inflation of the inflatable portion 12 with the pressurized fluid P. Accordingly, as a result of the substantially elliptical shape provided by the intermediate band portion 18c, the lower perimeter 18a_L of the upper dome portion 18a that is connected to the upper perimeter 18c_U of the intermediate band portion 18c may correspondingly define an elliptical shape (as seen at FIG. 4), and the upper perimeter 18b_U of the lower bowl portion 18b that is connected to the lower perimeter 18a_L of the intermediate band portion 18c may also correspondingly define an elliptical shape (as seen at FIG. 5).

In some implementations, the upper dome portion 18a includes a substantially flat top wall portion 34 (see, e.g., FIGS. 3, 4, and 6) and a curved, concave-down sidewall portion 36 (see, e.g., FIGS. 3, 4, and 6). The substantially flat top wall portion 34 is generally bounded by a perimeter region having, for example, a substantially rectangular shape (see, e.g., FIG. 4) defined by a length L₃₄ (see, e.g., FIGS. 4 and 6) and a width W₃₄ (see, e.g., FIG. 4). As seen at FIG. 6, the curved, concave-down sidewall portion 36 includes: (1) an upper region 36a extending from the perimeter region of the substantially flat top wall portion 34; (2) a lower region 36b extending from the first sealed flange 30 of the body 18; and (3) an intermediate region 36c extending between the upper region 36a of the curved, concave-down sidewall portion 36 and the lower region 36b of the curved, concave-down sidewall portion 36.

In some examples, the lower bowl portion 18b includes a substantially flat bottom wall portion 38 (see, e.g., FIGS. 5 and 6) and a curved, concave-up sidewall portion 40 (see, e.g., FIGS. 5 and 6). The substantially flat bottom wall portion 38 is generally bounded by a perimeter region having, for example, a substantially rectangular shape (see, e.g., FIG. 5) defined by a length L₃₈ (see, e.g., FIGS. 5 and 6) and a width W₃₈ (see, e.g., FIG. 5). As seen at FIG. 6, the curved, concave-up sidewall portion 40 includes: (1) a lower region 40a extending from the perimeter region of the substantially flat bottom wall portion 38; (2) an upper region 40b extending from the second sealed flange 32 of the body 18; and (3) an intermediate region 40c extending between the lower region 40a of the curved, concave-up sidewall portion 40 and the upper region 40b of the curved, concave-up sidewall portion 40.

In some examples, the width W₃₄ of substantially flat top wall portion 34 may be approximately equal to 20.0 to 30.0 centimeters (cm), and the length L₃₄ of substantially flat top wall portion 34 may be approximately equal to 40.0 to 60.0 centimeters (cm) thereby providing a surface area of the substantially flat top wall portion 34 that may be approximately equal to 800 to 1,800 square-centimeters (cm²). Furthermore, in some examples, the width W₃₈ of substantially flat bottom wall portion 38 may be approximately equal to 25.0 to 35.0 centimeters (cm), and the length L₃₈ of substantially flat bottom wall portion 38 may be approximately equal to 45.0 to 55.0 centimeters (cm) thereby providing a surface area of the substantially flat bottom wall portion 38 that may be approximately equal to 1,125 to 1,925 square-centimeters (cm²). Accordingly, some implementations of the inflatable portion 12 may provide a surface area ratio of the substantially flat bottom wall portion 38 to the substantially flat top wall portion 34 that is approximately 1.00:1.14.

With reference to FIG. 7, at approximately a region of the intermediate region 36c of the curved, concave-down sidewall portion 36 may form a valve-receiving opening 42 that is sized for supporting the valve 16 on the body 18 of the inflatable portion 12. Once the valve 16 is arranged within the valve-receiving opening 42 and fluidly-secured to the body 18, the fluid-receiving cavity 20 of the body 18 of the inflatable portion 12 is sealed from surrounding atmosphere A.

Referring to FIGS. 3 and 4, in some instances, the first fluid barrier sheet forming the upper dome portion 18a may include a one or more material-concentrated seams 44a-44e. The one or more material-concentrated seams 44a-44d may demarcate the curved, concave-down sidewall portion 36 into a plurality of regions, such as, for example: (1) a first curved, concave-down sidewall end region 36₁ that defines the valve-receiving opening 42; (2) a second curved, concave-down sidewall region 36₂ arranged opposite the first curved, concave-down sidewall end region 36₁; (3) a front curved, concave-down sidewall region 36₃; and (4) a rear curved, concave-down sidewall region 36₄ arranged opposite the front curved, concave-down sidewall region 36₃. The material-concentrated seam 44e, however, does not demarcate the curved, concave-down sidewall portion 36 into a region, but, rather, may reinforce a portion of the intermediate region 36c of the curved, concave-down sidewall portion 36 that forms the valve-receiving opening 42

Referring to FIGS. 5 and 6, in some instances, the second fluid barrier sheet forming the lower bowl portion 18b may include a one or more material-concentrated seams 46a-46d. The one or more material-concentrated seams 46a-46d may demarcate the curved, concave-up sidewall portion 40 into a plurality of regions, such as, for example: (1) a first curved, concave-up sidewall end region 40₁; (2) a second curved, concave-up sidewall region 40₂ arranged opposite the first curved, concave-up sidewall end region 40₁; (3) a front curved, concave-up sidewall region 40₃; and (4) a rear curved, concave-up sidewall region 40₄ arranged opposite the front curved, concave-up sidewall region 40₃.

The one or more material-concentrated seams 44a-44e, 46a-46d may be formed by selectively heating, selectively ultra-sonically welding, or other suitable bonding of one or more regions of, respectively, the first fluid barrier sheet and the second fluid barrier sheet. The one or more material-concentrated seams 44a-44e, 46a-46d may assist in the distribution of an externally-applied force F or applied weight (see, e.g., FIG. 6) from surrounding atmosphere A to the inflatable portion 12 that may be substantially perpendicular to an underlying support surface or ground surface G. (see, e.g., FIG. 6). Although the externally-applied force F is shown being applied in a direction toward the substantially flat top wall portion 34 in FIG. 6 (while the substantially flat bottom wall portion 38 is arranged opposite the underlying support surface or ground surface G), in other instances, the inflatable portion 12 could be flipped over such that the externally-applied force F could be applied to the substantially flat bottom wall portion 38 (while the substantially flat top wall portion 34 is arranged opposite the underlying support surface or ground surface G).

In some examples, the externally-applied force F may arise from one or both of a user's feet arranged upon the substantially flat top wall portion 34 of the upper dome portion 18a of the body 18 of the inflatable portion 12. In some implementations, one or a combination of the selected materials and the structural configuration of the inflatable portion 12 may withstand an externally-applied force F or applied weight or load that may be less than or approximately equal to a user that may weigh approximately, for example, 700 pounds (lbs.), 500 pounds (lbs.), 300 pounds (lbs.), or the like. Although the inflatable portion 12 may be configured to withstand an externally-applied force F or applied weight or load of a plurality of differently-sized users, the inflatable portion 12 may be configured to withstand any type of user that may weight, for example, greater than 700 pounds (lbs.).

Referring to FIG. 7, the upper dome portion 18a, the lower bowl portion 18b, and the intermediate band portion 18c of the body 18 respectively includes an inner surface 18a_I, 18b_I, 18c_I. The inner surfaces 18a_I, 18b_I, 18c_I of the upper dome portion 18a, the lower bowl portion 18b, and the intermediate band portion 18c of the body 18 define the fluid-receiving cavity 20 for containing the pressurized fluid P. The upper dome portion 18a, the lower bowl portion 18b, and the intermediate band portion 18c of the body 18 also respectively include an outer surface 18a_O, 18b_O, 18c_O that face surrounding atmosphere A.

As also see at FIG. 7, in some implementations, the inflatable portion 12 may include a plurality of ribs 48 that define a skeletal load support matrix disposed within the fluid-receiving cavity 20. With reference to FIG. 7, the plurality of ribs 48 may include a first rib 48₁, a second rib 48₂, a third rib 48₃, a fourth rib 48₄, and a fifth rib 48₅ (whereby, for example, the second rib 48₂, the third rib 48₃, and the fourth rib 48₄ may be referred to as intermediate rib whereas the first rib 48₁ and the fifth rib 48₅ may be referred to as end ribs). In some implementations, each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may be formed from a polymer material, such as, for example, a polyurethane material in a substantially similar manner as that of the one or more fluid barrier sheets that form the upper dome portion 18a, the lower bowl portion 18b, and the intermediate band portion 18c of the body 18 of the inflatable portion 12.

Referring to FIG. 7, when each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 is viewed in a cross-sectional length-wise direction along the length L₁₂ of the inflatable portion 12, each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may include: (1) a first segment 48a (see also FIG. 8) attached to the inner surface 18a_I of the upper dome portion 18a; (2) a second segment 48b attached to the inner surface 18b_I of the lower bowl portion 18b; and (3) a third segment 48c (see also FIG. 8) extending between and connecting the first segment 48a to the second segment 48b. In some examples, the third segment 48c includes: (1) a first end 48c_I connected to the first segment 48a for defining a first living hinge 50 (see also FIG. 8) of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48; and (2) a second end 48c₂ connected to the second segment 48b for defining a second living hinge 52 of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48.

With reference to FIG. 10, each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may include a height H₄₈, an upper width W_48-U (see also, e.g., FIG. 4) that extends along a portion of the width W₁₂ of the inflatable portion 12, and a lower width W_48-L (see also, e.g., FIG. 5) that extends along a portion of the width W₁₂ of the inflatable portion 12. Furthermore, as seen at FIG. 10, each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 includes a first sidewall 48d of the third segment and a second sidewall 48e of the third segment 48c each having an upper end extending between the upper width W_48-U and each having a lower end extending between the lower width W_48-L.

The first living hinge 50 extends along the upper width W_48-U of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48. The second living hinge 52 extends along the lower width W_48-L of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48.

As seen at FIG. 10, the lower width W_48-L may be greater than the upper width W_48-U; therefore, each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may define a substantially trapezoidal shape when the inflatable portion 12 is viewed in a width-wise direction along the width W₁₂ of the inflatable portion 12. Accordingly, the first sidewall 48d of the third segment 48c may extend away from the second segment 48b at an acute angle θ_48d, and the second sidewall 48e of the third segment 48c may extend away from the second segment 48b at an acute angle θ_48e.

In some implementations, the upper width W_48-U of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may be approximately equal to 15.0 to 25.0 centimeters (cm). In other implementations, the lower width W_48-L of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may be approximately equal to 20.0 to 30.0 centimeters (cm).

Because each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48, the upper dome portion 18a, the lower bowl portion 18b, and the intermediate band portion 18c of the body 18 may be formed from a polymer material, such as, for example, a polyurethane material, the inflatable portion 12 may be arranged in a substantially folded-flat, rolled or other compact state when the inflated portion 12 is arranged in a deflated state. Furthermore, as a result of incorporation of the first living hinge 50 and the second living hinge 52, when the inflatable portion 12 is transitioned from an expanded-and-inflated state to a compact-and-deflated state by evacuating the pressurized fluid P out of the valve 16, each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 is permitted to “diagonally fall” or “diagonally collapse” upon on one another (in a similar fashion as that of a series of dominos that tip over an adjacent domino in successive order) while remaining attached to inner surfaces 18a_I, 18b_I of the upper dome portion 18a and the lower bowl portion 18b as will be described in the following disclosure.

With reference to FIG. 4, in some configurations, the third segment 48c of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may be spaced apart from an opposing third segment 48c of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 at distance or spacing S₄₈ along the length L₁₂ of the inflatable portion 12. The length-wise distance or spacing S₄₈ of opposing third segments 48c of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may be approximately equal to 8.0 centimeters (cm).

Referring to FIG. 8, each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 is defined by a rib thickness T₄₈. In some implementations, the rib thickness T₄₈ may be approximately equal to 0.5 to 2.00 centimeters (cm).

Each of the first segment 48a and the second segment 48b of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 is defined by a length (see, e.g., length L_48a of the first segment 48a of the rib 48₃ at FIG. 8). In some implementations, the length L_48a of each of the first segment 48a and the second segment 48b of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may be any desirable length ranging from, for example, about 0.5 centimeters (cm) to about 1.5 centimeters (cm). In some instances, the length L_48a may be approximately equal to 1.0 centimeters (cm).

With reference to FIG. 7, the third segment 48c of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 is defined by a length L_48c. The length L_48c of the third segment 48c of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 is slightly less than the H₁₂ of the inflatable portion 12. Furthermore, the length L_48c of the third segment 48c of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 is slightly less than the height H₄₈ of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 when the inflatable portion 12 is arranged in the inflated state; when the inflatable portion 12 is arranged in the inflated state, the height H₄₈ of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 is defined by: (1) the length L_48c of the third segment 48c of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48; (2) the rib thickness T₄₈ of the first segment 48a of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48; and (3) the rib thickness T₄₈ of the second segment 48b of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48. In some implementations, the length L_48c of the third segment 48c of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may be any desirable length ranging from, for example, about 10.0 centimeters (cm) to about 15.0 centimeters (cm). In some instances, the length L₄₈c may be approximately equal to 12.5 centimeters (cm).

The first segment 48a of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may be joined to the inner surface 18a_I of the upper dome portion 18a by use of an adhesive or material deformation such as, for example, heating or ultra-sonic welding. The second segment 48b of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may be joined to the inner surface 18b_I of the lower bowl portion 18b by use of an adhesive or material deformation such as, for example, heating or ultra-sonic welding.

In an exemplary method of manufacturing the inflatable portion 12, in a first step, the valve 16 is secured to the valve-receiving opening 42 formed by the body 18 of the inflatable portion 12. Then, in a second step, the first segment 48a of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may be joined to the inner surface 18a_I of the upper dome portion 18a. Then, in a third step, the second segment 48b of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may be joined to the inner surface 18b_I of the lower bowl portion 18b. Then, in a fourth step, the first sealed flange portion 30 may be formed by a sealed connection of: (1) a lower perimeter 18a_L of the first fluid barrier sheet forming the upper dome portion 18a to (2) an upper perimeter 18c_U of the third fluid barrier sheet forming the intermediate band portion 18c. Then, in a fifth step, the second sealed flange portion 32 may be formed by a sealed connection of: (1) an upper perimeter 18b_U of the second fluid barrier sheet forming the lower bowl portion 18b to (2) a lower perimeter 18c_L of the third fluid barrier sheet forming the intermediate band portion 18c.

When the inflatable portion 12 is arranged in an inflated state with a pressurized fluid P as seen at FIG. 7, the third segment 48c of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 extends substantially perpendicularly with respect to: (1) a region of the inner surface 18a_I of the upper dome portion 18a that is bound by the substantially flat top wall portion 34 of the upper dome portion 18a; and (2) a region of the inner surface 18b_I of the lower bowl portion 18b that is bound by the substantially flat bottom wall portion 38 of the lower bowl portion 18b. Furthermore, when the inflatable portion 12 is arranged in an inflated state with a pressurized fluid P as seen at FIG. 7, each of the first segment 48a and the second segment 48b of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 extends substantially perpendicularly with respect to the third segment 48c at, respectively, the first living hinge 50 and the second living hinge 52 thereby defining each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 to have a substantially C-shape (see, e.g., FIGS. 3 and 7).

With continued reference to FIG. 7, when the inflatable portion 12 is arranged in an inflated state with a pressurized fluid P, the length L_48c of the third segment 48c of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 functions as a tether and limits a distance D₁₈ that the inner surface 18a_I, 18b_I of each of the upper dome portion 18a and the lower bowl portion 18b are permitted to travel away from one another within the confines of the substantially flat top wall portion 34 of the upper dome portion 18a and the substantially flat bottom wall portion 38 of the lower bowl portion 18b. Therefore, upon being inflated with the pressurized fluid P, the inflatable portion 12 limits the height H₁₂ of the inflatable portion 12 that extends between: (1) the outer surface 18a_O of the body 18 that is bound by the substantially flat top wall portion 34 of the upper dome portion 18a; and (2) the outer surface 18b_O of the body 18 that is bound by the substantially flat bottom wall portion 38 of the lower bowl portion 18b.

Because each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 functions as a tether as described above, the inflatable portion 12, when inflated, does not form a spherical shape. More specifically, when the inflatable portion 12 is inflated, the inflatable portion 12 may be confined to a generally rectangular cuboidal space according to, for example, the length L₁₂, width W₁₂, and the height H₁₂ of the inflatable portion 12. Therefore, as a result of one or a combination of structural features (e.g., the inclusion of the plurality of ribs 48 that function as tethers), the inflatable portion 12 is prevented from ever forming a spherical shape.

As described above, the one or more material-concentrated seams 44a-44e, 46a-46d may assist in the distribution of the externally-applied force F (see, e.g., FIG. 6) to the inflatable portion 12. Furthermore, in addition to each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 functioning as a tether as described above, each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may also assist in the distribution of the externally-applied force F or applied weight or load to the inflatable portion 12.

In addition to each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 functioning as a tether as described above, like the one or more material-concentrated seams 44a-44e, 46a-46d, each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 may assist in the distribution of the externally-applied force F (see, e.g., FIG. 6) to the inflatable portion 12 that may be substantially perpendicular to an underlying support surface or ground surface G. (see, e.g., FIG. 6).

Furthermore, as seen at FIGS. 7-8, upon being inflated with the pressurized fluid P, the outer surface 18a_O of the upper dome portion 18a that defines the substantially flat top wall portion 34 of the upper dome portion 18a includes a textured pattern such as, for example, a tread pattern. The tread pattern is defined by plurality of peaks or bulging portions 54 that extend, in parallel along the width W₁₂ of the inflatable portion 12, and a plurality of grooves 56 that extend, in parallel along the width W₁₂ of the inflatable portion 12.

The plurality of bulging portions 54 include a first bulging portion 54₁, a second bulging portion 54₂, a third bulging portion 54₃, and a fourth bulging portion 54₄. The plurality of grooves 56 include a first groove 56₁, a second groove 56₂, a third groove 56₃, a fourth groove 56₄, and a fifth groove 56₅. The first bulging portion 54₁ is arranged between the first groove 56₁ and the second groove 56₂. The second bulging portion 54₂ is arranged between the second groove 56₂ and the third groove 56₃. The third bulging portion 54₃ is arranged between the third groove 56₃ and the fourth groove 56₄. The fourth bulging portion 54₄ is arranged between the fourth groove 56₄ and the fifth groove 56₅.

Similarly, as seen at FIG. 7, upon being inflated with the pressurized fluid P, the outer surface 18b_O of the lower bowl portion 18b that defines the substantially flat bottom wall portion 38 of the lower bowl portion 18b includes a textured pattern such as, for example, a tread pattern. The tread pattern is defined by plurality of peaks or bulging portions 58 that extend, in parallel along the width W₁₂ of the inflatable portion 12, and a plurality of grooves 60 that extend, in parallel along the width W₁₂ of the inflatable portion 12.

The plurality of bulging portions 58 include a first bulging portion 58₁, a second bulging portion 58₂, a third bulging portion 58₃, and a fourth bulging portion 58₄. The plurality of grooves 60 include a first groove 60₁, a second groove 60₂, a third groove 60₃, a fourth groove 60₄, and a fifth groove 60₅. The first bulging portion 58₁ is arranged between the first groove 60₁ and the second groove 60₂. The second bulging portion 58₂ is arranged between the second groove 60₂ and the third groove 60₃. The third bulging portion 58₃ is arranged between the third groove 60₃ and the fourth groove 60₄. The fourth bulging portion 58₄ is arranged between the fourth groove 60₄ and the fifth groove 60₅.

As described above, each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 functions as a tether and limits the distance D₁₈ that the inner surface 18a_I, 18b_I of each of the upper dome portion 18a and the lower bowl portion 18b are permitted to travel away from one another. As seen at FIG. 7, the illustrated exemplary distance D₁₈ may define a maximum distance that extends between: (1) a region proximate a peak of each bulging portion 54₁, 54₂, 54₃, 54₄ of the plurality of bulging portions 54 of the of the upper dome portion 18a that defines the substantially flat top wall portion 34 of the upper dome portion 18a; and (2) a region proximate a peak of each bulging portion 58₁, 58₂, 58₃, 58₄ of the plurality of bulging portions 58 of the of the lower bowl portion 18b that defines the substantially flat bottom wall portion 38 of the lower bowl portion 18b.

With reference to FIG. 8, each groove 56₁, 56₂, 56₃, 56₄, 56₅ of the plurality of grooves 56 formed by the outer surface 18a_O of the upper dome portion 18a includes a trough surface 62 that may define a trough width W₆₂. The trough width W₆₂ may be approximately equal to or slightly greater than the length L_48a of the first segment 48a of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48. Although not shown, each groove 60₁, 60₂, 60₃, 60₄, 60₅ of the plurality of grooves 60 formed by the outer surface 18b_O of the lower bowl portion 18b may include a trough surface having a width that may be approximately equal to or slightly greater than the length of the second segment 48b of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48. Accordingly, each groove 56₁, 56₂, 56₃, 56₄, 56₅ of the plurality of grooves 56 formed by the outer surface 18a_O of the upper dome portion 18a, and, each groove 60₁, 60₂, 60₃, 60₄, 60₅ of the plurality of grooves 60 formed by the outer surface 18a_O of the lower bowl portion 18b may be axially aligned with (see, e.g., rib axis A₄₈-A₄₈ in FIG. 8) and arranged opposite, respectively, the first segment 48a and the second segment 48b of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48.

In view of the above-described exemplary configuration of the inflatable portion 12, the shape, size, and placement of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 contributes to a desired structural configuration that promotes use of the inflatable portion 12, alone, or, in combination with the outer casing portion 14, such that the assembly 10 functions as an abdominal core strength training exercise device or “stability board”. For example, by selectively forming the lower width W_48-L of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 to be greater than the upper width W_48-U of each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48, the substantially rectangular shape (see, e.g., the length L₃₈ by the width W₃₈ in FIG. 5) of the substantially flat bottom wall portion 38 is greater than the substantially rectangular shape (see, e.g., the length L₃₄ by the width W₃₄ in FIG. 4) of the substantially flat top wall portion 34; accordingly, if a user wants to conduct a more challenging exercise by reducing the stability of the assembly 10 (or, the inflatable portion 12, alone), the user merely flips over the assembly 10 (or, the inflatable portion 12, alone) such that the smaller surface area defined by the substantially flat top wall portion 34 faces or is disposed adjacent the underlying support surface or ground surface G. Furthermore, because each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 provides a dual function as tethers and force-distributing components, each rib 48₁, 48₂, 48₃, 48₄, 48₅ of the plurality of ribs 48 promotes the formation of the tread pattern imparted to the substantially flat top wall portion 34 and the substantially flat bottom wall portion 38 in order to increase friction against the underlying support surface or ground surface G or a sole surface of a user's shoes or feet while also distributing the externally-applied force F that may be substantially perpendicular to an underlying support surface or ground surface G as a result of a user standing on the assembly 10 (or, the inflatable portion 12, alone). Yet even further, the selected materials and structural configuration of the inflatable portion 12 results in the ability of the inflatable portion 12 to support relatively large loads that may support a user's entire body weight whereby the user may weigh, for example, approximately 700 pounds (lbs.).

Referring now to FIGS. 11-14, exemplary aspects of the outer casing portion 14 are shown. When the inflatable portion 12 is arranged in an expanded state and is disposed within the cavity 24 formed by the body 22 of the outer casing portion 14, the body 22 generally defines the outer casing portion 14 to include a length L₁₄ (see, e.g., FIGS. 12-14), a width W₁₄ (see, e.g., 12-13), and a height H₁₄ (see, e.g., FIG. 14).

As described above, the body 22 of the outer casing portion 14 includes a first opening 26 (see, e.g., FIGS. 12 and 14) and a second opening 28 (see, e.g., FIGS. 11 and 12). While the second opening 28 is configured to permit the valve 16 of the inflatable portion 12 to pass there-through (as seen at, e.g., FIG. 2), the first opening 26 is configured to permit insertion of the body 18 of the inflatable portion 12 into the cavity 24 of the body 22 of the outer casing portion 14 (generally in a direction according to arrow in D_12-14 FIG. 1).

The body 22 may be formed from any desirable material that may be laundered, washed, disinfected, or the like. As will be explained in the following disclosure, the body 22 may be configured to be arranged in an expanded state that is substantially similar to, but larger than the inflatable portion 12 after the inflatable portion 12, which when arranged inside the cavity 24 of the body 22, is inflated for being arranged in an expanded state itself. However, in other instances, the body 22 of the outer casing portion 14 may be arranged in a substantially folded-flat, rolled or other compact state (not shown) when the inflatable portion 12, which may or may not be arranged in the cavity 24 of the body 22, is not arranged in the inflated state.

In some implementations, the body 22 may be formed from a lightweight denier material such as, for example, nylon or a ripstop nylon. In some instances, the body 22 may be formed from a lightweight denier material including a urethane coating such as, for example, a polyurethane coating or a thermoplastic polyurethane coating. In other examples, the body 22 may be formed from a combination of ripstop nylon material and a urethane coating such as, for example, a polyurethane coating or a thermoplastic polyurethane coating.

According to an exemplary method of assembling the assembly 10, in some implementations, the inflatable portion 12 may be initially arranged in a compact-and-deflated state whereby the body 18 of the inflatable portion 12 has not yet taken the shape of the upper dome portion 18a, the lower bowl portion 18b, and the substantially elliptically-shaped intermediate band portion 18c as seen and described above at FIGS. 3-10 (i.e., the inflatable portion 12 may be initially arranged in a substantially folded-flat, rolled or other compact state). Accordingly, when the inflatable portion 12 is initially arranged in the compact-and-deflated state, the inflatable portion 12 is inserted through the first opening 26 of the body 22 of the outer casing portion 14 (according to, e.g., the direction of the arrow D_12-14 in FIG. 1) such that the inflatable portion 12 is arranged within the cavity 24 of the body 22 of the outer casing portion 14.

Once arranged inside the cavity 24 of the body 22 of the outer casing portion 14, the valve 16 may be aligned with and pulled through the second opening 28 of the body 22 of the outer casing portion 14. The body 22 may also include a reinforcement ring 29 (see, e.g., FIGS. 11-12) circumscribing the second opening 28 in order to reduce wear of the body 22 if the valve 16 is successively pulled there-through and subsequently pushed there-through as a result of multiple assembling and disassembling processes imparted to the assembly 10. The reinforcement ring 29 may be made from a plastic material, a rubber material, or the like.

A user may then access the valve 16 in order to pressurize the fluid-receiving cavity 20 of the body 18 of the inflatable portion 12 with a pressurized fluid P while the inflatable portion 12 is arranged within the cavity 24 of the body 22 in a deflated state. In some instances, the valve 16 may be configured to be interfaced with an air pump (not shown) that provides the pressurized fluid P. In other examples, the valve 16 may be configured to permit a user to apply their lips to the valve 16 for manually depositing (i.e., “blowing up”) the fluid-receiving cavity 20 of the body 18 of the inflatable portion 12 with air from the user's lungs. Accordingly, as the inflatable portion 12 is inflated with the pressurized fluid P, the outer casing portion 14 is shaped by the inflatable portion to an expanded state as seen, for example, at FIGS. 11 and 14. Conversely, when the user desires arrangement of one or both of the inflatable portion 12 and the outer casing portion 14 in a compact (i.e., deflated) state, the user arranges the valve 16 in an open state and applies an external force to the body 18 of the inflatable portion 12 for evacuating the pressurized fluid P from the cavity 20 of the body 18 of the inflatable portion 12.

With reference to FIGS. 11-14, the body 22 of the outer casing portion 14 may include a plurality of panel portions that may be secured (e.g., stitched) to one another. The plurality of panels defining the body 22 of the outer casing portion 14 may include: (1) a top panel configured to include a dome shape 22a (see, e.g., FIGS. 11, 12, and 14) that configures a portion of the cavity 24 of the outer casing portion 14 for containing the upper dome portion 18a of the inflatable portion 12; (2) a bottom panel configured to include a bowl shape 22b (see, e.g., FIGS. 11, 13, and 14) that configures another portion of the cavity 24 of the outer casing portion 14 for containing the lower bowl portion 18b of the inflatable portion 12; and (3) an intermediate panel configured to include a ring shape 22c (see, e.g., FIGS. 11, 12, and 14) that configures yet another portion of the cavity 24 of the outer casing portion 14 for containing the intermediate band portion 18c of the inflatable portion 12.

With reference to FIGS. 12 and 14, the intermediate panel configured to include the ring shape 22c of the body 22 of the outer casing portion 14 defines the first opening 26 of the body 22 of the outer casing portion 14. As seen at FIG. 14, the outer casing portion 14 may further include a closure element 64. The closure element 64 may be secured to the intermediate panel configured to include the ring shape 22c of the body 22. The closure element 64 extends across or over the first opening 26 in order to provide selective access to the cavity 24 of the outer casing portion 14. Although the first opening 26 may be formed by the intermediate panel configured to include the ring shape 22c of the body 22 of the outer casing portion 14, the first opening 26 may be formed by any panel of the outer casing portion 14 (e.g., the top panel configured to include the dome shape 22a or the bottom panel configured to include the bowl shape 22b); accordingly, the closure element 64 may be alternatively secured to either of the top panel configured to include the dome shape 22a or the bottom panel configured to include the bowl shape 22b.

In some implementations, the closure element 64 may include a zipper including a body of material 66 supporting cooperating teeth 68 that are selectively joined by a slider 70. In some examples, the body of material 66 of the closure element 64 may also include a docking bay or “garage” 72 for receiving the slider 70 when the closure element 64 seals or closes out the first opening 26. Although the closure element 64 is described above to include a zipper; other closure elements 64 may be utilized such as, for example, VELCRO®.

In some implementations, the top panel configured to include the dome shape 22a of the body 22 of the outer casing portion 14 may be sized to include a substantially flat top wall panel portion 74 (see, e.g., FIGS. 11, 12, and 14) that corresponds to a substantially similar size and shape of the substantially flat top wall portion 34 of the upper dome portion 18a of the inflatable portion 12. Furthermore, in other implementations, the bottom panel configured to include the bowl shape 22b of the body 22 of the outer casing portion 14 may be sized to include a substantially flat bottom wall panel portion 76 (see, e.g., FIGS. 11, 13, and 14) that corresponds to a substantially similar size and shape of the substantially flat bottom wall portion 38 of the lower bowl portion 18b of the inflatable portion 12.

In some implementations, one or both of the substantially flat top wall panel portion 74 and the substantially flat bottom wall panel portion 76 may include a textured pattern 78 (see, e.g., FIGS. 11-13) that promotes friction when arranged adjacent, for example, one or both of, for example, a sole surface of a user's shoes (not shown), the underlying support surface or ground surface G (see, e.g., FIG. 14), or the like. In some examples, the textured pattern 78 may include the lightweight denier material defining one or both of the substantially flat top wall panel portion 74 and the substantially flat bottom wall panel portion 76 having a hashed or crisscross stitched pattern (not shown). In other examples, the textured pattern 78 may include the lightweight denier material defining one or both of the substantially flat top wall panel portion 74 and the substantially flat bottom wall panel portion 76 having a printed silicon gel pattern (e.g., an “array of circular dots” as seen at FIGS. 11-12, an “array of hexagons” as seen at FIG. 13, or any other desirable shape or size). In some configurations, the printed silicon gel pattern may include a “left foot print” (not shown) and a “right foot print” (not shown) in order to infer placement of a user's left foot and a user's right foot upon one or both of the substantially flat top wall panel portion 74 and the substantially flat bottom wall panel portion 76. Although the textured pattern 78 may include one or both of hashed or crisscross stitched pattern of the lightweight denier material and a printed silicon gel pattern, any desirable configuration promoting friction of the substantially flat top wall panel portion 74 and the substantially flat bottom wall panel portion 76 may be utilized.
