Abstract: A golf tee is provided for use with a driving range mat. The tee has a base portion that extends into a hole in the mat, and terminates below the upper surface of the mat. A generally semi-rigid tee portion is slidable in the base portion so the tee portion is vertically adjustable. The base is made of a resilient material, and has an upper wall divided into segments. The hole in the mat may be sized to squeeze the segments inwardly to grip the tee portion more firmly. The tee portion has a base received within the base portion so the tee portion cannot be easily removed from the base portion. The diameter of the base portion is sufficient that the tee portion will not engage the mat when the tee is hit by a golf club, to prevent degradation of the mat.

Abstract: Artificial athletic turf has a simulated grass surface provided by tufting strips into a backing fabric. The tufts are held in place by a precoat of polyurethane, and a reinforcing sheet is embedded within the precoat to provide tear resistance. A formed polyurethane is placed on the precoat, and one or more reinforcing sheet are also embedded within the foamed polyurethane. The strips are hydrophobic plastic with strength to prevent damage, and the coatings are polyurethane reinforced for tear resistance, which also yields a resilience as needed for an athletic mat. A hole can be cut into the mat, and the hole reinforced with a sleeve, to receive a tee for use as a golf mat.

Abstract: Artificial athletic turf has a simulated grass surface provided by tufting strips into a backing fabric. The tufts are held in place by a precoat of polyurethane, and a reinforcing sheet is embedded within the precoat to provide tear resistance. A foamed polyurethane is placed on the precoat, and one or more reinforcing sheets are also embedded within or placed on the foamed polyurethane. The strips are hydrophobic plastic with strength to prevent damage, and the coatings are polyurethane reinforced for tear resistance, which also yields a resilience as needed for an athletic mat. One or more of the fibrous sheets may be needle felt to provide some of the needed resilience. The turf is cut along lines parallel and perpendicular to the tufting lines to provide tiles, and the tiles are assembled to form the desired turf.
