A shock absorbing mat/tile comprises a body having a generally planar, major top surface and an opposite bottom surface and a plurality of shock absorbing members depending from the bottom surface. At least one of the shock absorbing members has at least one relief formation formed therein configured to accommodate lateral expansion of the shock absorbing member during axial compression thereof.

A floor assembly for a performance space is disclosed. The assembly has a planar resilient floor board supported above a base board on a primary support system comprising a plurality of resilient (preferably elastomeric) supports. A secondary support system comprises a plurality of fixed support members and a plurality of movable support members. Each movable support member is movable in a direction parallel to the plane of the floor board between a first position spaced from a corresponding fixed support member such that the floor board is unsupported by the support members and a second position in contact with the corresponding fixed support member such that the floor board is supported by the support members. In the first position, the floor board is in a sprung configuration and in the second position, the floor board is in an unsprung configuration. The invention therefore provides a performance floor which is switchable between sprung and unsprung configurations.

A structural element, including a base portion and a connecting central pin, has its base portion formed hallow, and having an internal reinforcement in the shape of WOW or MOM, to connect these elements with an insertable central pin so that the cross-section of the pin corresponds to the shape of the chamber between the reinforcements, when the upper surface of the structural element has longitudinal grooves, and is made from a modified polymer or elastomeric material comprising India rubber mixtures. The foundation is monomer ethylene propylene diene or natural rubber or styrene-butadiene rubber and/or combinations of the natural rubber/styrene-butadiene rubber, or thermoplastic elastomers, whose base is monomer ethylene-propylene-diene or polypropylene/monomer ethylene-propylene-diene or polyvinylchloride, or thermoplastic vulcanizates, whose base is monomer ethylene-propylene-diene and polyethylene or natural and/or synthetic rubber, modified by polyethylene or polypropylene.

The membrane is for use with a planar surface and includes a generally planar member and a plurality of resilient tabs. The generally planar member, in use, is disposed in parallel relation to and adjacent the planar surface and, at least in use, defines a plurality of troughs, the troughs being interconnected to define a planar network of troughs that is disposed parallel to the surface, each trough presenting away from the surface in use and terminating in a common plane that is parallel to and spaced from the surface. The tabs are provided for each of one or more of the troughs, the tab lying in the common plane and spanning at least in part across said each trough.

Reinforced tiles, as well as systems and methods for reinforcing tiles, are provided. The reinforced tiles have enhanced durability, compressive strength, shear strength, and modulus of elasticity.

A composite epoxy resin board, made from a raw material which includes the following weight percentage of components: waste prepreg powders of 5% to 100%, and waste printed circuit board (PCB) powders of 0% to 95%, is disclosed. The present invention adopts the waste prepregs as the main preparation raw material, which not only recycles and reuses prepreg scraps, but also reduces or even eliminates the use of adhesives due to the high epoxy resin content in the prepregs, while also reducing the glue-mixing time in the forming process, thereby simplifying the forming technology.

Floating floor (10) with at least one vibration-damping support (1) that is placed on a solid underground (5), whereby the support (1) comprises a relatively rigid support slat (3) provided with discrete vibration-damping elements (2) on one side, distributed at a regular distance from each other over the support slat (3), and whereby the support slat (3) is provided with a vibration-damping strip (4) on a second side opposite the first side extending in the longitudinal direction of the support slat (3), such that the support slat (3) is situated between the vibration-damping strip (4) and the discrete vibration-damping elements (2) that are placed between the floor (10) and the underground (5), such that the floor (10) rests on the underground (5) by means of the vibration-damping strip (4), the support slat (3) and the discrete vibration-damping elements (2), whereby no direct mutual contact is made between the support slat (3), the floor (10) and the underground (5).

A composite floor structure and method of making the same are disclosed. The composite floor structure may include a platform and a plurality of transverse beams. The composite floor structure may also include at least one longitudinal beam and a plurality of insert beams to accommodate the longitudinal beam. The composite floor structure may also include an underlayment between the plurality of transverse beams and the at least one longitudinal beam. Some or all of these components may be integrally molded together to form a fiber-reinforced polymer structure. The composite floor structure may be used for cargo vehicles and other applications.

A multi-tiered recoiling energy absorbing system has an upper impact surface that is exposed to percussive impact. At least one energy absorbing layer is positioned below or inside the upper impact surface. The energy absorbing layer includes one or more energy absorbing modules. At least some of the modules are provided with one or more energy absorbing units that extend from an upper platform. Several of the energy absorbing units are provided with a flexible wall that extends from the upper platform. A lateral reinforcement member secures the energy absorbing units to prevent them from splaying. The energy absorbing units at least partially absorb energy generated by an impacting object due to the flexible wall bending inwardly or outwardly and recoiling nondestructively after single or multiple impacts to its un-deflected configuration.

An interlocking modular mat having four sides has female connectors on two sides and male connectors on the other two sides so that the modular mat can interlock with an adjacent mat and its connectors. The modular mat is configured with a plurality of structures surrounding a periphery of a top portion of the mat. The plurality of structures in combination with an underside of the top portion of the mat form a cavity. A sponge insert is configured to fit in the cavity and have a height such that a portion of the sponge insert extends from a bottom side the mat body. With the sponge insert extending beyond the bottom side of the mat body, the sponge insert bottom face generally become the supporting bottom of the modular mat to provide a more cushioned feel for a mat user.
