US Patent:

50265806, Jun 25, 1991

Filed:

Jul 25, 1990

Appl. No.:

7/557592

Inventors:

Mark A. Hammon - Woodward IA

Assignee:

AGR Inc. - Perry IA

International Classification:

A63B 6936

US Classification:

428 17

Abstract:

A golf mat of grass-like material includes top and bottom pads each of which includes belting material which substantially strengthens them and protects the base mat from damage from golf clubs striking it. The golf tee extends only through the top pad and not through the base mat and the belting material of the top pad prevents any enlargement of the hole through the top pad which includes felt carpet which also gives a grass-like appearance. The top pad is loosely secured to the base mat and may be raised at its center for replacement of the tee and the top pad absorbs energy from the golf club due to its ability to move relative to the base mat when it is struck. The pad may be replaced through operation of the bolts at its opposite ends. In an alternate embodiment the turf layer includes filaments of yarn such as tufts partially exposed on the bottom side adjacent fabric-like material exposed on the top side of the layer of belting material. Adhesive is applied to these two surfaces forms chemical and mechanical bonds therebetween by the adhesive penetrating the two layers and encapsulating the exposed tufts and fabric material.
