A series of interconnectable foam-block ramps and platforms are provided that are cut from low density EPS foam but coated with durable exterior polyurea coating, and that include optional hard surfaces, and edge-and-corner treatments, and railing with hand grips. The components resist deformation and withstand extreme weather conditions, but are surprisingly lightweight and include integral hook connectors that securely engage. They can be easily assembled / installed to form a handicap ramp and / or arranged to form novel “terrains” for wheeled devices and / or arranged to form stages and platforms. The components are sufficiently durable to support high-stress wheeled devices such as a wheelchairs, trick bikes, skateboards, in-line skates and the like. A variety of optional components include a curb-simulating element, intersection-forming platforms, X-intersection connectors, double-decker platforms, steps, and railings.

Each longitudinal edge of each insert has two deep recesses and a central shallow recess. A plurality of generally I-shaped concealed locking beams have a central section and parallel end sections. Each end section has a central region of a thickness less than end regions to form a locking ramp. A pair of similarly configured metal facings for each concealed locking beam with opposed end parts are located within the deep recesses at the longitudinal edges of each insert. Each end part terminates in a V-shaped projection configured to allow the end regions of the concealed edge lockings to compress the V-shaped projections and allow the end regions of the concealed locking beams to mate with the metal facings.

Artificial knee joint
InactiveUS20110082558A1Maximum flexionEasy to bendJoint implantsKnee jointsFemoral componentSurface geometry
An artificial knee joint comprise a femoral component and tibial component. The posterior side of the femoral component comprises medial and lateral condyles, wherein the width and offset of the posteromedial condyle is greater than the width and offset of the posterolateral condyle. At the posterior the tibial bearing component comprises medial and lateral articulating surface geometries, wherein the posterior slope of the lateral articulating geometry is greater than the posterior slope of the medial articulating geometry. The medial articulating surface geometry of the tibial bearing component supports the medial condyle of the femoral component and the lateral articulating surface geometry of the tibial bearing component supports the lateral condyle of the femoral component. The greater slope of the lateral articulating geometry allows the femoral component condyle to roll down to the posterior during knee flexion. This invention of an artificial knee joint for a prosthetic knee implant system facilitates deep knee flexes beyond 130 degrees.
