- There are many circumstances in which hard, inflexible ground covering materials are not beneficial to the human body. For example, in high-traffic areas, hard flooring may cause ailments such as knee problems and the like. In workplace environments, such as factory floors, and other areas in which people generally must stand, hard flooring may cause back and other problems. In health and fitness environments, hospitals and physical therapy facilities, the use of hard flooring may be minimized to prevent injury. Playgrounds are an example of where injuries may be caused by abrupt or unintended contact with hard surfaces.
- For most people, the possibility of injury caused by abrupt, unintended or persistent jarring contact with hard flooring or other ground covering surfaces will exist. In order to minimize risk of injury, protective covering materials have been previously introduced in areas such as playgrounds, weight rooms, jogging tracks, exercise rooms, factory floors, etc. Conventional protective floorings may be configured in various sizes with softening or impact absorbing materials. Unconsolidated loose fill materials (e.g., such as sawdust and wood chips) are in widespread conventional use.
- Rubber flooring is another alternative to minimize impact shock and has been used in many of the environments described vide supra. Examples of this type of flooring have been sold or otherwise marketed under the tradenames PLAYBOUND, PLAYGUARD and FX tile. Examples of these types of flooring compositions for exercise facilities and the like include EVEROLL, EVERLAST and ECO tiles and generally constitute a top layer (e.g., wear surface) and a backing layer that provides cushioning and shock absorption characteristics for particular applications.
- While these types of rubber floorings are effective for providing cushioning and protecting against injury from abrupt or jarring impact, conventional products offered in the market have substantial limitations. For example, the material and the manufacturing processes used limits the applicability of rubber flooring in various functional and aesthetic environments. For example, in environments where liquids may be spilled (e.g., restaurants, cafeterias, swimming pools, and the like), the use of porous surfaces generally allows the penetration of the liquid into the material, which may result in damage to the material. Therefore, it would be beneficial to provide a flexible paver and manufacturing process capable of producing a tile having a top layer that may be generally less porous.
- Additionally, conventional products and materials used for protective flooring applications have been limited in their aesthetic appeal by the restriction of available materials and textures. Due to the materials used and the processes of manufacture, options relating to aesthetic appearance have been limited, thereby rendering the use of flexible flooring materials less attractive to potential customers. It would, therefore, be advantageous to provide ground covering compositions in which the aesthetic appeal of the product is enhanced.
- In representative aspects, the present invention provides systems, devices and methods for providing protective flooring or ground-covering compositions capable of demonstrating enhanced durability as well as aesthetic appeal. Advantages of the present invention will be set forth in the Detailed Description which follows and may be apparent from the Detailed Description or may be learned by practice of exemplary embodiments of the invention. Still other advantages of the invention may be realized by means of any of the instrumentalities, methods or combinations particularly disclosed in the claims.
- Representative elements, operational features, applications and/or advantages of the present invention reside inter alia in the details of construction and operation as more fully hereafter depicted, described and disclosed—reference being made to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout. Other elements, operational features, applications and/or advantages will become apparent in light of certain exemplary embodiments recited in the Detailed Description, wherein:
