Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
A laminated golf mat comprising, a first layer of durable flexible belting-type material having top and bottom sides, woven fabric-like material embedded in said first layer and being partially exposed on the top side of said layer, a second layer of turf having top and bottom sides on the top side of said first layer and said turf having filaments of yarn exposed on the bottom side adjacent the fabric-like material in the top side of said first layer, and adhesive between said first layer and said second layer forming chemical and mechanical bonds between said filaments and fabric material.
Claim 2
Dependent Claim
100 words
A laminated golf mat comprising, a first layer of durable flexible belting-type material having top and bottom sides, woven fabric-like material embedded in said first layer and being partially exposed on the top side of said layer, a second layer of turf having top and bottom sides on the top side of said first layer and said turf having filaments of yarn exposed on the bottom side adjacent the fabric-like material in the top side of said first layer, and adhesive between said first layer and said second layer forming chemical and mechanical bonds between said filaments and fabric material.
Claim 3
Dependent Claim
12 words
The structure of claim 1 wherein said filaments are defined by tufts.
Claim 4
Dependent Claim
20 words
The structure of claim 1 wherein a cushion layer is adhesively bonded to the bottom side of said first layer.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
34 words
The structure of claim 1 wherein said layer of turf includes a perforated sheet and said tufts extend through said perforations providing tuft portions on opposite top and bottom sides of said perforated sheet.
Claim 7
Dependent Claim
51 words
The structure of claim 5 wherein said tufts are U-shaped and include oppositely disposed interconnected leg portions with free ends, said connection of said legs being on the bottom side of said turf layer and said free ends of said legs being on the top side of said layer of turf.
Claim 8
Dependent Claim
25 words
