Abstract:
Liquid-permeable floor covering for floors that can be walked or driven on, and the like, made of two or more layers (1, 2), joined over the whole surface, of a cellular elastic plastic, with each floor-side layer (1) being considerably thicker than each surface-side layer (2), with the side of the covering in contact with the floor having in the corresponding floor-side layer liquid-drainage channels (3, 3') running in parallel and spaced apart formed in it, with further channels (4) branching off from these channels at intervals and running through the or each floor-side layer, these further channels (4) being cut or shaped into the or each floor-side layer (1) and opening downwards.
Abstract:
본 고안은 보행자가 통행하기 위한 인도에 시공되어지는 보도블럭에 있어서, 특히 통상의 보도블럭 하부 바닥면에 다양한 형태 및 크기, 배열상태를 갖는 요철면을 형성함으로서, 일차 성형된 보도블럭을 상,하로 적층하여 가열로 내부에서 경화시키는 경우, 상기 요철면에 의해 통기성이 원활하게 확보되도록 하여, 상하로 적재된 보도블럭이 서로 접착 경화되는 것을 방지하므로, 보도블럭의 제작시간 및 인원이 크게 감축됨은 물론 번거로운 중간과정이 생략되므로 보다 대량 생산에 적합한 것이며, 인도에 시공될 경우 하부 모래층과의 결합력이 우수하게 되어 빗물 등이 유입되더라도 모래층의 유실을 최소화하므로 보도블럭이 흔들리거나 유동하는 것을 방지하면서도, 보도블럭의 하측에 빗물 등이 고이는 것을 방지할 수 있어 인도의 포장상태를 장기간 동안 안정적으로 유지할 수 있는 효과를 갖는 요철의 바닥면을 갖는 보도블럭에 대한 것이다.
Abstract:
An impact-absorbing assembly includes a covering layer being one or more of artificial turf, rubber mats, polymer mats, short pile carpeting, particulate infill, wood chips, and ground rubber chips. Also included is a layer of underlayment panels positioned beneath the covering layer. The panels have a panel section with a plurality of drain holes formed therethrough. A top surface of the panels is configured to support the covering layer. A bottom surface of the panels has a plurality of bottom projections that cooperate to define bottom channels suitable to permit water flow across the bottom surface, the bottom channels being in fluid communication with the panel drain holes. The bottom projections define a first spring rate characteristic that is part of a first stage and a second spring rate characteristic is part of a second stage, the first stage having a smaller volume of material than the second stage.

Abstract:
A playing surface comprising a supportive base layer, an intermediate layer such as a foam layer, and a surface layer, wherein the base layer is configured to provide the playing surface with a first predetermined amount of stability and the intermediate layer, e.g. foam layer, is configured to provide the playing surface with an additional, second predetermined amount of stability, the intermediate layer, e.g. foam layer, being further configured to conform to a required performance standard. And a method of constructing a playing surface.

Abstract:
A modular cell that may be used with other cells to form a matrix under a load bearing feature, the cell being a single piece moulding that supports a compressive load placed thereon, the moulding including a void space defined within: a skirt shaped support member defining a substantially planar surface with an opening therein; and at least one leg integral to and extending from the support member. The cell further includes at least one separate linking member that releasably links together multiple cells to form a matrix of cells. The cells may be linked together vertically and/or horizontally. The cell and matrix include greater load bearing capacity and rigidity through aligned legs to carry the weight as well as interlinking members that act to share the load among the various cells. The design also requires less material hence is cheaper to produce. The void space is also easily accessed hence allowing for easy access, filling and laying of utility lines where needed.
