With the advent of ergonomics, and realization by the public of their general utility, support pads have gained increasing favorability. Moreover, these physical support pads have shown an expansion in their functional use: from improving work comfort or fatigue reduction, to physical fitness and the practice of yoga. In fact, these pads have taken a number of forms in the fitness realm, including rollable and non-rollable mats, as well as puzzle-piece floor cushions that assemble from two or more pieces.
Mats are certainly useful as a support pad, but are static in nature, bulky to manipulate, unfriendly to transport, and generally unable to adjust to different demands of ever-changing fitness. Puzzle-piece floor cushions have an advantage over static mats by creating flexible sizing, as well as adjustable shapes for the changing fitness needs. Although puzzle-piece floor cushions solve the adjustability issue, they are often made of sub-optimal materials given their intended purpose is outside the fitness arena, and therefore are not designed to possess the properties suitable for use in fitness. Moreover, and more importantly, puzzle-piece floor cushions require cumbersome effort to separate and reposition during active fitness activity given their vertical interlock requirements that are not amenable to the functional fitness demands necessitating the ability to move quickly from one physical move to another.
Functional fitness, and activities like yoga, demand the ability to move quickly from one move/position to another, and coincidentally sliding longitudinally across the floor from one move/position to another. However, the existing support pads are not designed to accommodate such movement nor quick re-configuration, interrupting the activity or even causing injury.
As such, there remains a need for improved physical support pads that offer flexible sizing, adjustable shapes for changing fitness needs, as well as offer quick and secure re-configuration. In particular, there is a need for such physical support pads with highly responsive fitness properties, anti-slip characteristics, stack ability, and increased durability to withstand active and functional fitness needs.
Accordingly, the present invention is directed to physical support pads constructed as paired pallet slip-lock systems that offer flexible sizing, adjustable shapes for changing fitness needs, as well as offer quick and secure re-configuration. The slip-lock systems of the present invention afford a longitudinal interlocking mechanism between paired structural pallet segments that offers not only fastening security, but also longitudinal separation. In particular, the present invention provides physical support pads with highly responsive fitness properties and increased durability to withstand active and functional fitness needs.
One aspect of the present invention is directed to a physical support pad constructed as a paired pallet slip-lock system comprising at least two structural pallet segments of expanded polyurethane foam wherein the two structural pallet segments comprise a first structural pallet segment shaped to incorporate a slip-lock cavity defined by a narrowing cavity with two anchor toggles positioned one on each side of the cavity; and a second structural pallet segment shaped to incorporate a slip-lock anchor defined to match the slip-lock cavity comprising two anchor tabs on each side of the slip-lock anchor, wherein the anchor tabs are positioned such that the anchor toggles and the anchor tabs are adjacent when the paired pallet segments are in interlocked position; wherein the first and second structural pallets are suitably flexible such that the slip-lock anchors of the second structural pallet segment may longitudinally slip past the anchor toggles of the first structural pallet segment to interlock as a paired pallet, and wherein the two segments longitudinally separate only when the release force exceeds the force required to longitudinally flex one or more of the anchor toggles or the anchor tabs.
Another aspect of the present invention is directed to a travel physical support pad comprising a physical support pad of the present invention, wherein the pad diameter across any axis of symmetry is about 10 inches, e.g., suitable in size for carrying during travel, but large enough to be remain useful for its intended purpose.
Another aspect of the present invention is directed to a physical support pad expansion kit comprising one or more expansion structural pallet segments for use in conjunction with the physical support pad of the present invention, wherein each expansion structural pallet segment comprises at least one of:
Advantages of the present systems and kits will be apparent from the following detailed description, which description should be considered in combination with the accompanying figures, which are not intended to limit the scope of the invention in any way.
The present invention is directed to physical support pads constructed as paired pallet slip-lock systems that offer flexible sizing, adjustable shapes for changing fitness needs, as well as offer quick and secure re-configuration. The slip-lock systems of the present invention afford a longitudinal interlocking mechanism between paired structural pallet segments that offers not only fastening security, but also longitudinal separation. In particular, the present invention provides physical support pads with highly responsive fitness properties, such as energy return and joint protection and increased durability to withstand active and functional fitness needs.
In particular, the physical support pads of the present invention utilize slip-lock systems of the present invention that offer secure fastening of paired structural pallet segments during active and functional fitness. The interlock system of the present invention provides stability of the interlocked pallet segments and helps keep the segments together to retain configurations during exercise like yoga, but also allows quick and secure longitudinal reconfiguration of the segments for functional fitness allowing quick movement from one physical move to another by sliding pallet segments together or apart in the plane of the floor, e.g., sliding the segments across the floor toward and away from each other to interlock and separate the segments, respectively; in stark contrast to existing support pads.

The pellets of the infiltrated composite material may be quickly placed in a foaming apparatus and heated to 110° C. to foam, and the foamed particles may be expanded numerous times, e.g., 8 times.
In certain embodiments of the present invention, the e-TPU particles may be obtained from recycled material, e.g., recovered from previously molded particles.
In certain embodiments, the prepared expanded thermoplastic polyurethane particle foam particles are placed in a steam molding device by steam compression molding to prepare a plate mold having a defined thickness. In particular, this technology uses steam to weld foam into components, for example, through the diffusion and entanglement of molecular chains at the interface, the small TPU molecules made of solid particles are expanded like popcorn, and the beads are bonded in the mold to be processed into a product of the desired shape/mold. The prepared plate mold is cut into several pieces by using a slicer and skived to create layers of smaller thickness, e.g., between about ⅜ inch and about 1 inch, e.g., between about ⅜ inch and about ½ inch.
In certain embodiments, the process of steam molding includes injecting the foamed particles into a molding die, introducing high temperature steam into the mold, where the high temperature steam passes through the forming mold for a period of time and then is cooled into a cooling water setting.
