Description
- The present disclosure is directed to pad structures that protect and/or wrap at partially around a pole, stand or other structure, particularly in sports environments.
- The presence of poles, stands, support structures, and the like (generally referred to as structures) in areas where there is physical activity and foot traffic may present a health hazard. Pads, guards, covers, and other protective members (generally referred to as protective members) have been used to reduce the health hazard of such structures and protect the structures from damage. Known protective members often provide inadequate shock absorption, padding, and protection both for the structure and individuals. Shock absorption is especially important for structures located in areas where sporting activities take place. Another limitation of many types of protective members is their inability to adapt to structures of different sizes and shapes. A still further limitation of many protective members is difficulties associated with mounting and dismounting the protective members relative to the structure.
- Opportunities exist for improvements in protective members for use in covering structures, and particularly structures used in sports environments.
- One aspect of the present disclosure relates to an inflatable pad that provides variable amounts of shock absorption depending on the inflated state of the pad. Another aspect of the present disclosure relates to an inflatable pad that has an adjustable size to fit structures (e.g., a pole or stand) of different sizes.
- Another aspect of the present disclosure relates to an inflatable pad that includes a cover member, at least one inflatable member, and at least one fastening member configured to releasably secure the inflatable pad to a stand or pole. The cover member includes an outer pad layer, an inner pad layer, and a cavity defined between the outer and inner pad layers where the at least one inflatable pad is positioned.

Wrapping the inflatable pad may include wrapping the inflatable pad around less than an entire perimeter of the stand or pole. Wrapping the inflatable pad may include wrapping the inflatable pad around an entire perimeter of the stand or pole. The method may include at least partially deflating the at least one inflatable member to adjust an amount of shack absorption provided by the inflatable pad.
- A further aspect of the present disclosure relates to an inflatable pad that includes an outer cover and at least one inflatable member. The outer cover defines an internal cavity and is adjustable between an open, planar arrangement when disconnected from a structure to be protected, and a mounted, non-planar arrangement when mounted to the structure to be protected. The at least one inflatable member is positioned in the cavity and configured to be inflated and deflated to adjust a thickness of the inflatable pad.
- The outer cover may include a vinyl material. The inflatable pad may include at least one fastening member configured to releasably secure the inflatable pad to the structure. The at least one inflatable member may include a plurality of inflatable members. The plurality of inflatable members may be connected in flow communication with each other.

FIG. 1 illustrates an exampleinflatable pad 10 mounted to a sports structure in the form of avolleyball pole 18. Theinflatable pad 10 wraps around thepole 18, and theinflatable pad 10 is secured to itself and/or directly topole 18 to maintain the attached or mounted state shown inFIG. 1 . Theinflatable pad 10 may include acover member 12, a plurality ofinflatable members 14, and one or more fastening members 16. Theinflatable members 14 are positioned within thecover member 12. Fastening members 16 provide a connection of theinflatable pad 10 to a structure such as thepole 18. Typically, the fastening members provide a releasable attachment of theinflatable pad 10 to a structure. - Referring to
FIG. 2 , thecover member 12 includes anouter layer 20, aninner layer 22 and acavity 24 formed between the outer andinner layers FIGS. 3A-3C illustrate first and second side edges 26, 28 of thecover member 12.FIG. 1 illustrates top andbottom edges cover member 12. In at least some embodiments, thecavity 24 is accessible along the first and second side edges 26, 28 and/or along the top andbottom edges cover member 12 is closed or sealed along one or more of the first and second side edges 26, 28 and/or the top andbottom edges cavity 24. In at least some embodiments, thecavity 24 is open and/or accessible along one or more of theedges inflatable members 14 for the purpose of inflating and deflating theinflatable members 14. In other embodiments, one or more access points are provided through the outer orinner layers inflatable members 14. - When the
inflatable pad 10 is mounted to apole 18 or other structure, the first and second side edges 26, 28 may abut against each other as shown inFIG. 2 such that there is a continuous arrangement ofinflatable members 14 within thecavity 24 and around a perimeter of thepole 18. Theinflatable pad 10 may form a center opening 36 (seeFIG. 2 ) within which thepole 18 is positioned when theinflatable pad 10 is in a mounted state or position as shown inFIGS. 1 and 2 . Thepole 18 may have a diameter D1 as shown inFIG. 4 . Thecenter opening 36 may also has a diameter D1 such that theinflatable pad 10 wraps completely around thepole 18. - The fastening member 16 may include a
flap 50 that overlaps a portion of theouter layer 20 to secure theinflatable pad 10 to thepole 18. Theflap 50 may include hook and/orloop fasteners 52B that connect with hook and/orloop fasteners 52A positioned on the outer surface ofouter layer 20 as shown inFIG. 2 . -
FIG. 4 shows an alternative attachment arrangement in which the fastening members 16 include a plurality ofstraps 54 that wrap around an exterior of thecover member 12 and are releasably secured together (e.g., using hook and loop fasteners, buckles, or the like) to releasably secure theinflatable pad 10 to thepole 18. The fastening members 16 may have other configurations and functionality in other embodiments, most of which provide a releasable attachment of theinflatable pad 10 topole 18 or other structure. - The
inflatable members 14 may each have the same cross-sectional shape as shown in at leastFIG. 2 . Theinflatable members 14 may extend from thetop edge 30 to thebottom edge 32 of thecover member 12. Theinflatable members 14 may be inflated and deflated through an inflation stem and/orvalve 40. As discussed above, theinflation stem 40 may extend through the cover member 12 (e.g., through one of outer orinner layers 20, 22). Alternatively, theinflation stem 40 may be accessible at an openings intocavity 24 via, for example, along one of the first and second side edges 26, 28 and/or along one of the top andbottom edges inflatable members 14 are only inflatable and not deflatable (e.g., via a one-way valve that is not reversible or replaceable). - The
inflatable members 14 may be connected in flow communication with each other via a plurality of flow connections 42 (e.g., seeFIG. 3A ). The flow connections 42 may be positioned at any location along the length of theinflatable members 14. In embodiments in which all of theinflatable members 14 are in flow communication with each other via the flow connections 42, theinflation stem 40 may be positioned on any one of theinflatable members 14, or a plurality of theinflatable members 14. - In other embodiments, the
inflatable members 14 are separately inflatable. For example, less than all of theinflatable members 14 may be connected in flow communication with each other (e.g., using one or more of the flow connections 42). In at least some arrangements, none of theinflatable members 14 are connected in flow communication with the other inflatable members.FIG. 13 illustrates an embodiment in which a plurality of inflatable members 614 a are connected in flow communication viaflow connections 642, and a second plurality of inflatable members 614B are connected via separate flow connections 642 b. By providing flow communication amongstinflatable members 14 of different sets of inflatable members in the inflatable pad, the user may provide customized changes in size, shape and/or shock absorption capability for various portions and/or sections of the inflatable pad.FIG. 13 shows the sets of inflatable members 614A, 614B arranged side by side within acavity 624 of thecover member 612. The inflatable members are shown in a fully inflated state inFIG. 13 that provides a thickness T1 for thecover member 12. By deflating one or both of these sets of inflatable members 614A, 614B, the thickness T1 may be decreased a desired amount, and may provide a modified and/or customized shock absorption capability for theinflatable pad 610. - The
inflatable members 14 shown inFIGS. 1-4 have a generally circular cross-sectional shape when in a fully inflated state (e.g., seeFIG. 3A ).FIG. 3B shows theinflatable members 14 in a partially deflated state and having a non-circular, generally oval cross-sectional shape.FIG. 3C shows theinflatable members 14 in a fully deflated state and having a further elongated oval cross-sectional shape. The thickness for the cover member 12 (e.g., a width of the cavity 24) may change from a thickness T1 inFIG. 3A when inflatable members are fully inflated, to a reduced thickness T2 in a partially deflated state as shown inFIG. 3B , and have a thickness T3 in a fully deflated state as shown inFIG. 3C . -
FIGS. 3A-3C illustrate how theinflatable members 14 may change cross-sectional shape between various stages of inflation. In other embodiments, theinflatable members 14 may maintain the same cross-sectional shape in one or more of the inflated states, wherein the outer perimeter size (e.g., diameter) may vary for the inflatable members between various inflated states. -
FIGS. 5A and 5B illustrate other cross-sectional shapes forinflatable members inflatable members FIG. 5A as compared to the at least partially deflated state shown inFIG. 5B . For example, the generally unilateral triangular shape ofinflation members 214A may change to an isosceles triangular shape inFIG. 2B . The square cross-sectional shape of theinflatable members 214B may change from the inflated state shown inFIG. 5A to a rectangular shape shown inFIG. 5B . The rectangular shape of theinflatable members 214C shown inFIG. 5A may change to a generally square cross-sectional shape when at least partially deflated as shown inFIG. 5B . The various cross-sectional shapes shown inFIGS. 5A and 5B are exemplary of the many cross-sectional shapes that may be possible for the inflatable members disclosed herein. Other example cross-sectional shapes may include, for example, hexagonal, trapezoidal, hemispherical, spherical, and the like. - The
inflatable members 14 may have a generally cylindrical shape with a greater length than maximum cross-sectional shape, as shown in at leastFIG. 1 . In other embodiments, theinflatable members 14 may have a varying cross-sectional shape and/or size along its length rather than a constant cross-sectional shape and size along its length. In still further embodiments, the inflatable members include a plurality of interconnected “bubble” or hemispherical-shaped structures similar to bubble wrap rather than having cylindrical shaped inflatable members. -
FIGS. 15-16B illustrate an exampleinflatable pad 810 that includes a plurality of interconnected bulbous-shapedinflatable members 814.FIG. 15 shows theinflatable pad 810 without theinner layer 822 of thecover 812 in order to better illustrate theinflatable members 814. Theinflatable members 814 are interconnected withflow connections 842. Although theinflatable members 814 are shown spaced apart, other arrangements may provide for the inflatable members to be positioned adjacent to and/or in contact with each other. Theinflatable pad 810 may provide a thickness T1 when theinflatable members 814 are fully inflated as shown inFIG. 16A .FIG. 16B shows theinflatable members 814 at least partially deflated so as to provide a thickness T2. One or more inflation stems 840 may provide inflation and deflation of theinflatable members 814 within thecavity 824. While the fully inflatedinflatable members 814 have a generally hemispherical shape as shown inFIGS. 15 and 16A , other shapes are possible including the generally flattened shape shown inFIG. 16B , or outer perimeter shapes that are non-circular. For example, the flattened shape shown inFIG. 16B may be the fully inflated state for the inflatable members. - Referring now to
FIG. 6 , another exampleinflatable pad 310 is shown including a plurality ofinflatable members 14 positioned within separate cavities 324. The cavities 324 are defined by connection points between the outer andinner layers separate inflation stem 340 to provide inflation and deflation of theinflatable members 14. In other embodiments, theinflatable members 14 are interconnected with flow connections, or at least some of theinflatable members 14 are interconnected with flow connections. The connection points between the outer andinner layers inflatable pad 310 may bend to create, for example, a corner, curve or other deformation that may assist in adapting the shape of theinflatable pad 310 to a particular shape for a given structure to which theinflatable pad 310 is mounted. For example, theinflatable pad 310 with multiple hinge points 334 may more easily wrap around a plurality of 90° corners on a structure, or may more easily bend to wrap around an oval or circular-shaped structure such aspole 18. - The size and shape of the cavities 324 may vary depending on the inflated state of the
inflatable members 14. In at least some arrangements, the size and shape of the cavities 324 may substantially match the outer perimeter size and shape of the inflatable members 14 (e.g., when theinflatable members 14 are in a fully inflated state). In other embodiments, the cavities 324 may maintain a generally constant cross-sectional area, but may change cross-sectional shape as theinflatable members 14 are inflated and deflated. Alternatively, the cavities 324 may maintain a generally constant cross-sectional shape that may change cross-sectional area as theinflatable members 14 are inflated and deflated. - As mentioned above, the inflatable pads disclosed herein may be adaptable to structures of different sizes and/or shapes.
FIG. 7 illustrates another arrangement for theinflatable pad 10 shown inFIGS. 1-3C . Theinflatable pad 10 is shown wrapped around apole 18A having a smaller diameter D2 than thepole 18 shown in at leastFIGS. 1 and 4 . Because of the smaller diameter D2, thesecond side edge 28 extends over or wraps around and beyond thefirst side edge 26 so that there is at least some overlap of theinflatable pad 10 upon itself around the circumference of thepole 18A. Theflap 50 may be used to secure the inflatable pad to thepole 18A using a releasable connection such as, for example, the hook andloop fasteners FIG. 4 ) may be used in place of or in addition to theflap 50 to releasably secure theinflatable pad 10 to a structure (e.g.,pole 18A). Due to the overlap of theinflatable pad 10 upon itself as shown inFIG. 7 , at least some of theinflatable members 14 may have different inflated cross-sectional sizes and/or shapes. In at least some embodiments, theinflatable pad 10 may be at least partially wrapped around and then secured to a structure (e.g.,pole 18A) and then the inflatable members are inflated or further inflated to provide a desired amount of padding, shock absorption, size or shape for theinflatable pad 10. In still further embodiments, the amount of air within each of theinflatable members 14 may self-adjust depending on the amount of force being applied to specific ones of the inflatable members. For example, theinflatable members 14 that are overlapping each other inFIG. 7 may have a reduced amount of air and thereby have a reduced cross-sectional area/size while the remaining inflatable members may have a generally constant cross-section of size and shape due to self-regulation of pressure and/or volume of air within theinflatable members 14. - Referring now to
FIGS. 8-9 , another exampleinflatable pad 410 is shown and described in use with astand 19. Thestand 19 has aframe 15 and steps 17. Theinflatable pad 410 is configured to wrap around a portion of theframe 15 while still providing open access to thesteps 17. - The
inflatable pad 410 includes outer andinner layers FIG. 9 . Thecover 412 may include a plurality ofsections 438A-438C that separately extend along a primary surface of thestand 19. A plurality ofinflatable members 414 are positioned within the cavity 424. Theinflatable members 414 may extend from atop end 430 to abottom end 432. Theinflatable pad 410 has side edges 426, 428 that are arranged at an angle θ1 relative to a vertical direction. The angle θ1 may be in the range of, for example, about 5° to about 60°, and more particularly in the range of about 15° to about 30°. The angled side edges 426, 428 may extend along an entire height of theinflatable pad 410. Alternatively, the angled orientation for the side edges 426, 428 may extend along only a portion of the length of the side edges 426, 428 between the top andbottom edges stand 19 or other structure to which theinflatable pad 410 is mounted. -
FIGS. 10-12B illustrate anotherexample cover 512, which may have some features that are similar to cover 412 shown inFIGS. 8 and 9 . Thecover 512 may include a plurality ofsections 538A-538C that separately extend along a primary surface of thestand 19. A plurality ofinflatable members 514 are positioned within thecavity 524. Theinflatable members 514 may change from one cross-sectional shape in a fully inflated state (seeFIGS. 11 and 12A ) to another cross-sectional shape when in an at least partially deflated state as shown inFIG. 12B . In other embodiments, such as thedeflatable pad 610 shown inFIG. 13 , the inflatable members may have a generally circular cross-sectional shape when in a fully inflated state. - The
inflatable members 514 may be inflatable and deflatable using one or more inflation stems 540 and associated valves. Theinflatable members 514 may be interconnected with flow connections, such as the flow connections 42 described above. The flow connections may provide concurrent inflation and deflation of some or all of theinflatable members 514. - The
inflatable pads stand 19. For example, theinflatable pads platform portion 11 of theframe 15. This arrangement provides for exposure of ahandrail 13 of theframe 15 for access by a user.

Aninflatable member 914 positioned in thecover member 12 has a single chamber construction and may be inflated/deflated using an inflation stems 40. Theinflatable member 914 may have a pre-formed shape. This pre-formed shape may be maintained at a plurality of inflated states. For example,FIG. 17A shows theinflatable member 914 having a first inflated state and an associated shape that wraps around thepole 18.FIG. 17B shows theinflatable member 914 in a second inflated state and having the same shape general shape asFIG. 17A , but in a reduced size (e.g., to wrap around apole 18 having a smaller diameter D2). Theinflatable member 914 may comprise elastic materials that facilitate expansion and contraction in the size of theinflatable member 914 between different inflated states while maintaining a similar shape. Thecover member 12 may also comprise elastic materials that expand and contact in size as theinflatable member 914 expands and contracts in size. The shape of thecover member 12 may also maintain a relatively constant shape as theinflatable member 914 expands and contracts as shown inFIGS. 17A and 17B . - In another embodiment, the
inflatable member 914 and/or covermember 12 may comprise inelastic materials, as illustrated inFIG. 17C . The material of theinflatable member 914 and/or covermember 12 may fold, bend or distort in shape when at least partially deflated from the inflated state shown inFIG. 17A . Theinflatable pad 910 shown inFIG. 17C may be adaptable to differentsized poles 18 or other structures to which theinflatable pad 910 may be mounted. - The
inflatable pad 910 may maintain the generally circular cross-sectional shape shown inFIGS. 17A-17C in a plurality of inflated states. Alternatively, theinflatable pad 910 may take on different shapes at various inflated states, such as the generally liner cross-sectional shape of theinflatable pad 1010 shown inFIGS. 18A and 18B . - The
inflatable pad 1010 may have at least some features that are similar to theinflatable pads inflatable pad 1010 may have a singleinflatable member 1014 and/or aninflatable member 1014 that has as single inflation chamber. Theinflatable member 1014 may be expandable between at least thicknesses T1, T2 as shown inFIGS. 18A and 18B . -
FIG. 19 shows anotherinflatable pad 1110 having a plurality ofsections 1138A-1138C that are separated by hinge or connection points 1134.

Other embodiments may include more or fewer than threesections 1138A-1138C, twoconnection points 1134, and threeinflatable members 1114A-1114C. Theinflatable pads inflatable members FIG. 14 . - The use of inflatable/deflatable members as part of a protected pad may have advantages related to compactness for storage and shipping when the inflatable members are completely deflated, while still providing the desired amount of cushioning, shock absorption, fit adaptability, etc. during use (e.g., when mounted to a structure such as a volleyball referee stand, volleyball pole, basketball standard support pole, soccer goal post, hockey goal post, baseball dugout barriers, football goal posts, practice equipment for a variety of sports, and the like). The inflated size and/or shape of the inflatable pad may be significantly greater than the deflated size and/or shape (e.g., about 10% to about 100% greater in thickness when inflated). In one example, the inflatable pad when in a deflated state may be generally planar with a minimum thickness. However, when the deflatable pad is inflated, it may take on a different shape such as a curved or domed shape, a cylindrical shape, or the like. By inflating the inflatable members of the inflatable pad, the inflatable pad may be adapted to provide an improved fit for the particular structure to which it is mounted.
- The materials used for the various components of the inflatable pad may vary depending on, for example, environmental conditions, uses, durability properties, expandability, flexibility, elasticity, and other desired and/or necessary properties.
