Abstract
A synthetic grass surface comprising widely spaced rows of ribbons and the ribbons having a length about twice as long as the spacing between the rows of ribbons. A particulate material is laid on a matrix of the synthetic grass, and the thickness of the particulate material is as least two-thirds the length of the ribbons.
Claims28
A synthetic surface having a flexible backing member, parallel rows of synthetic ribbons, representing blades of grass, projecting upwardly from the backing member, the rows of ribbons spaced apart from each other from between ⅝ inch and 2¼ inches, and the length of the ribbons, extending upwardly from the backing member, is at least twice the dimension of the spacing between the rows of ribbons, the surface including a relatively thick layer of particulate material on the backing member supporting the ribbons in a relatively upright position relative to the backing member, wherein the particulate layer has a thickness of substantially two-thirds the length of the ribbons.
A synthetic grass surface, wherein the synthetic grass surface comprises a flexible backing member, parallel rows of synthetic ribbons, representing blades of grass, projecting upwardly from the backing member, the rows of ribbons spaced apart from each other, the surface including a relatively thick layer of particulate material on the backing member supporting the ribbons in a relatively upright position relative to the backing member, wherein the relationship of the length of the ribbons and the spacing between the rows is
- 2A≦L
- such that the length of the ribbons is at least twice the spacing;
- and the particulate material having a thickness T of substantially ⅔ the length of the ribbons, when A is the spacing between the rows, L is the length of the ribbon measured from the flexible backing and T is the thickness of the layer of particulate material.
