摘要： An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises a core with a top side and a bottom side. The top side has a plurality of spaced apart, upwardly oriented projections that define channels suitable for water flow along the top side of the core when the underlayment layer is positioned beneath an overlying artificial turf assembly.

摘要： An inexpensive, lightweight, compressible, shock absorbing, and resilient fluid for use in padding applications is presented. A fluid pad can comprise closed-cell foam beads and a surrounding fluid housed in a thin plastic bladder. The closed-cell foam beads can be exactly flooded by the fluid. Alternatively, the fluid can lubricate the closed-cell foam beads. The surrounding fluid may also comprise solid phase microballoons. The addition of the closed-cell foam beads can result in the overall fluid in the bladder being lighter in weight. The fluid pad with the closed-cell foam beads can be compressible and resilient. The fluid pad with the closed-cell foam beads can be shock absorbing with respect to impact loads or vibrations. The addition of the closed-cell foam beads can lower the cost of the fluid pad insert.

摘要： Protective padding primarily intended for use in sports gear. In a first set of preferred embodiments, the pads include flexible, outer casings of porous, breathable, inelastic material overfilled with resilient, discrete beads of elastic material. The beads are initially in compressed states within the casing and place the outer, inelastic casing in tension. When a blow or force is applied, the beads are further compressed to absorb and dissipate the impact. Additionally, the applied blow or force will increase the tension in the outer casing to even further compress the elastic beads for better absorption and dissipation of the impact. In use, the porous pads are compressed and rebound to create a pumping effect that circulates air into and out of the pads drawing heat and perspiration from the athlete's body and keeping the athlete cool and dry. If desired, the pad can be secured directly to the athlete's jersey to enhance this pumping effect as well as the dissipation of the force of any impact. In an alternate embodiment, the outer casing is made of an elastic material that is overfilled to its elastic limit to act in the manner of the preferred embodiments. In a second set of preferred embodiments, the outer casings of the pads are actually filled no more than a simple gravity fill (i.e., 100%) and preferably are underfilled (e.g., 90%) to less than a gravity fill. This second set of pads is preferably used in combination with a hard, outer shell. Variations of the basic features of the first and second sets of pads are also disclosed. All of the pads of the present invention are lightweight and washable and can be adapted and integrated into a wide variety of items.
摘要翻译： 防护垫主要用于运动装备。 在第一组优选实施例中，垫包括多孔的，透气的非弹性材料的柔性外壳，其过度填充有弹性的离散的弹性材料珠。 珠子最初处于壳体内的压缩状态，并使外部非弹性套管处于张力状态。 当施加吹力或力时，珠被进一步压缩以吸收和消散冲击。 此外，施加的吹力或力将增加外壳中的张力，以进一步压缩弹性珠以更好地吸收和消散冲击。 在使用中，多孔垫被压缩和反弹以产生泵送效果，其将空气循环进入和吸出垫，从运动员的身体吸收热量和出汗并保持运动员的凉爽和干燥。 如果需要，垫可以直接固定到运动衫的球衣上，以增强这种泵送效果以及任何冲击力的消散。 在替代实施例中，外壳由弹性材料制成，该弹性材料超过其弹性极限以按照优选实施例的方式起作用。 在第二组优选实施例中，垫的外壳实际上填充不超过简单的重力填充（即，100％），并且优选地未填充（例如，90％）以小于重力填充。 该第二组垫优选与硬的外壳结合使用。 还公开了第一组和第二组焊盘的基本特征的变化。 本发明的所有垫都是轻质且可洗涤的，并且可以适应和集成到各种各样的物品中。

摘要： 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.

摘要： An artificial turf system includes a turf assembly having a turf backing and stands of artificial grass blades extending from the turf backing to form an artificial turf layer. Infill material is placed in between the blades of artificial grass and on top of the turf backing. The infill material has a composition of sand and organic particles. The infill material organic particles includes a plurality of wood particles where at least a portion of the wood particles define a length dimension oriented generally parallel to a grain structure of the wood particles. The length dimension is greater than a width or a thickness dimension and, in one example, may be in a range of about 0.5 mm to about 10 mm. The length dimension and one of the width or thickness dimensions may, in another example, define an aspect ratio within a range of 1:2 to 10:1.

摘要： An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises plurality of panels, each panel comprising a core with a top side and a bottom side. The top side has a plurality of top projections. The top projections form top side water drainage channels. The panels have edges, with the edges of one panel abutting the edges of adjacent panels, thereby forming a drainage path between adjacent panels. The panel edges have vertical support extensions that extend into the drainage paths between adjacent panels. The vertical support extensions have an upper surface for supporting an artificial turf assembly overlying the turf underlayment layer, and the panel edges having one or more complementary indentations corresponding to vertical support extensions of adjacent panels. When the panels move toward each other, thereby closing drainage paths between adjacent panels, the vertical support extensions are received in the corresponding indentations.

摘要： An artificial turf system includes a turf assembly having a turf backing and stands of artificial grass blades extending from the turf backing to form an artificial turf layer. Infill material is placed in between the blades of artificial grass and on top of the turf backing. The infill material has a composition of sand in an amount within the range of from about 80 to about 98 percent of the infill by dry bulk weight, and organic particles in an amount within the range of from about 2 to about 20 percent of the infill by dry bulk weight.
