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 form 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 presents 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 pad 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. 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 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: 20
Claim 1
Independent Claim
147 words
A laminated golf mat from which golf balls are driven at a driving range comprising, a first layer having top and bottom sides, fabric-like material in said first layer and being partially exposed on the top side of said first 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 said first and second layers including adhesive having points of intimate contact which are continuous and of sufficient quantity to penetrate said second layer around said filaments and said fabric-like material for forming chemical and mechanical bonds between said filaments and fabric material and rendering the first layer stiff and hard but flexible and energy absorbing upon being impacted by a golf club.
Claim 2
Dependent Claim
147 words
A laminated golf mat from which golf balls are driven at a driving range comprising, a first layer having top and bottom sides, fabric-like material in said first layer and being partially exposed on the top side of said first 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 said first and second layers including adhesive having points of intimate contact which are continuous and of sufficient quantity to penetrate said second layer around said filaments and said fabric-like material for forming chemical and mechanical bonds between said filaments and fabric material and rendering the first layer stiff and hard but flexible and energy absorbing upon being impacted by a golf club.
Claim 3
Dependent Claim
12 words
The structure of claim 1 wherein said filaments are defined by tufts.
Claim 4
Dependent Claim
34 words
The structure of claim 2 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 5
Dependent Claim
51 words
The structure of claim 3 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 6
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 7
Dependent Claim
13 words
The structure of claim 5 wherein said cushion layer is formed of foam.
Claim 8
Dependent Claim
25 words
The structure of claim 1 wherein said turf layer bottom side includes a pre-coat of urethane adhesive and said bonding adhesive is a urethane adhesive.
Claim 9
Independent Claim
177 words
The method of making a laminated golf mat from which golf balls are driven at a driving range comprising the steps of; providing a first layer having top and bottom sides with fabric-type material in said first layer partially exposed on the top side of said first layer, providing a second layer of turf material having top and bottom sides and having filaments exposed on said top and bottom sides, positioning said second layer of turf material on the top side of said first layer of material such that said filaments on the bottom side of said turf material are in close proximity to said fabric-type material, and applying adhesive between said first layer and said second turf layer having points of intimate contact which are continuous and of sufficient quantity to penetrate said second layer around said filaments and said fabric-like material for and forming chemical and mechanical bonds between said filaments and said fabric-type material and rendering the first layer stiff and hard but flexible and energy absorbing upon being impacted by a golf club.
Claim 10
Independent Claim
177 words
The method of making a laminated golf mat from which golf balls are driven at a driving range comprising the steps of; providing a first layer having top and bottom sides with fabric-type material in said first layer partially exposed on the top side of said first layer, providing a second layer of turf material having top and bottom sides and having filaments exposed on said top and bottom sides, positioning said second layer of turf material on the top side of said first layer of material such that said filaments on the bottom side of said turf material are in close proximity to said fabric-type material, and applying adhesive between said first layer and said second turf layer having points of intimate contact which are continuous and of sufficient quantity to penetrate said second layer around said filaments and said fabric-like material for and forming chemical and mechanical bonds between said filaments and said fabric-type material and rendering the first layer stiff and hard but flexible and energy absorbing upon being impacted by a golf club.
