Abstract
Abstract The edges of a synthetic turf material are secured by forming a slot in the base structure that supports the synthetic turf material and thereafter inserting the edge of the turf material to be secured into the slot with an elongated retainer strip being inserted into the slot to secure the turf in place. The elongated retainer strip is sized to frictionally engage one side of the elongated slot and the synthetic turf edge to urge it into frictional contact with the other side of the elongated slot.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
A method of securing the edges of a synthetic turf material which comprises: a. forming an elongated slot in a base supporting said turf material, said elongated slot having a first side wall and a second side wall; b. inserting the edge of said turf material to be secured into said slot; and c. thereafter inserting an elongated retainer strip into said slot whereby one face of said retainer strip frictionally engages said first wall of said slot and the other face of said retainer strip bears against said synthetic turf material to urge it into frictional engagement with said second side wall of said slot.
Claim 2
Independent Claim
106 words
A method of securing the edges of a synthetic turf material which comprises: a. forming an elongated slot in a base supporting said turf material, said elongated slot having a first side wall and a second side wall; b. inserting the edge of said turf material to be secured into said slot; and c. thereafter inserting an elongated retainer strip into said slot whereby one face of said retainer strip frictionally engages said first wall of said slot and the other face of said retainer strip bears against said synthetic turf material to urge it into frictional engagement with said second side wall of said slot.
Claim 3
Dependent Claim
16 words
The method of claim 1 wherein the said elongated slot is formed by cutting said base.
Claim 4
Dependent Claim
27 words
The method of claim 2 wherein said base is cut to form said elongated slot with said first side wall and said second wall being substantially parallel.
Claim 5
Dependent Claim
29 words
The process of claim 1 wherein an adhesive material for adhering said turf material to said base is injected into said slot before said elongated retainer strip is inserted.
Claim 6
Dependent Claim
33 words
The process of claim 1 wherein a volatile solvent material, capable of dissolving said elongated retainer strip and said synthetic turf material is injected into said slot before said retainer strip is inserted.
Claim 7
Dependent Claim
14 words
The process of claim 1 wherein said elongated retainer strip is a polymeric strip.
Claim 8
Dependent Claim
15 words
The process of claim 6 wherein said retainer strip is essentially a polyvinyl chloride material.
Claim 9
Dependent Claim
23 words
The process of claim 7 wherein a solvent material for polyvinyl chloride is injected into said slot before said retainer strip is inserted.
Claim 10
Dependent Claim
16 words
The process of claim 8 wherein said synthetic turf material is essentially a polyvinyl chloride material.
Claim 11
Dependent Claim
10 words
The process of claim 9 wherein said solvent comprises tetrahydrofuran.
Claim 12
Dependent Claim
39 words
The method of claim 1 wherein said elongated retainer strip is inserted into said slot to a depth whereby the upper end of said elongated retainer strip is flush with the surface of said base supporting said turf material.
