Abstract
Abstract A portable practicing putting green 44 having a putting surface band 11, a cup 91 at one end of it, a square angle 22 on the other end of it, and a rebound bar 32 replacably put on either side of the square angle or near the hole, for rebounding golf ball 47. The square angle 22 is bolted to one end of the putting surface band 11 and to its standing side is outwardly bonded a rubber plate 27 which is perpendicular to the center line 17 of the putting surface band 11. The rebound bar has four exposed planar side surfaces 31, 35, 37, 39 with three 35, 37, 39 of them bonded to a thin, medium, and thick rubber plates, respectively to provide different rebounding forces, and the remaining exposed 31 remaining bare. When it is being carried or stored, the rebound square bar is put in between the inner sides of the square angle 22 and the square angle and rebound bar 32 are wound up inside putting surface band 11 to minimize its volume.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
207 words
A portable practice putting green for use with a golf ball and golf putter, comprising: a putting surface band; a square angle; and a rebound square bar; said putting surface band being made of flexible material, and having a first two bolt holes at one end thereof which are on a line perpendicular to a center line of said putting surface band; a first rubber plate; said square angle being made of a rigid material having one exterior side bonded to said first rubber plate and having a second two bolt holes at an end of another side of said angle, said second bolt holes being bolted together with respective ones of said first bolt holes of said putting surface band; said rebound square bar being made of metal plated with another metal, and having three of four sides bonded by thin, medium, and thick rubber plates on three sides respectively with its fourth side remaining as a bare metal surface, disposable on said putting surface band and aside said first rubber plate of the square angle to expose a selected one of said four sides and thereby provide varying rebounding forces to a golf ball traveling along said putting surface band toward said rebound square bar.
Claim 2
Dependent Claim
207 words
A portable practice putting green for use with a golf ball and golf putter, comprising: a putting surface band; a square angle; and a rebound square bar; said putting surface band being made of flexible material, and having a first two bolt holes at one end thereof which are on a line perpendicular to a center line of said putting surface band; a first rubber plate; said square angle being made of a rigid material having one exterior side bonded to said first rubber plate and having a second two bolt holes at an end of another side of said angle, said second bolt holes being bolted together with respective ones of said first bolt holes of said putting surface band; said rebound square bar being made of metal plated with another metal, and having three of four sides bonded by thin, medium, and thick rubber plates on three sides respectively with its fourth side remaining as a bare metal surface, disposable on said putting surface band and aside said first rubber plate of the square angle to expose a selected one of said four sides and thereby provide varying rebounding forces to a golf ball traveling along said putting surface band toward said rebound square bar.
Claim 3
Dependent Claim
64 words
A portable practice putting green as defined in claim 1 wherein said putting surface band is made of flexible carpet, whereby when said rebound bar is disposed on said square angle and between bolts extending through said first and second bolt holes, said square angle may be wound inside said putting surface band to minimize volume of the putting green for storage and carriage.
Claim 4
Dependent Claim
27 words
A portable practicing putting green as defined in claim 1 where a cup is located at an end of said putting surface longitudinally opposite the square angle.
Claim 5
Dependent Claim
31 words
A portable practice putting green as defined in claim 2, wherein a cup is located at an end of said carpet longitudinally opposite from said one end and the square angle.
Claim 6
Dependent Claim
162 words
A portable practice putting green, comprising: an elongate putting surface made of flexible material and having a first two holes at one end thereof; a first rubber plate; an angle made of a rigid material having one exterior side bonded to said first rubber plate and having a second two holes at an end of another side of said angle, said angle being disposed perpendicular across the width of said putting surface with said second holes being aligned with respective ones of said first holes of said putting surface; and a rigid rebound bar having three of four sides bonded by thin, medium, and thick rubber plates on three sides respectively with its fourth side remaining as a bare surface, disposable on said putting surface and aside said first rubber plate of the angle to expose a selected one of said four sides and thereby providing varying rebounding forces to a golf ball traveling along said putting surface toward said rebound bar.
Claim 7
Dependent Claim
162 words
A portable practice putting green, comprising: an elongate putting surface made of flexible material and having a first two holes at one end thereof; a first rubber plate; an angle made of a rigid material having one exterior side bonded to said first rubber plate and having a second two holes at an end of another side of said angle, said angle being disposed perpendicular across the width of said putting surface with said second holes being aligned with respective ones of said first holes of said putting surface; and a rigid rebound bar having three of four sides bonded by thin, medium, and thick rubber plates on three sides respectively with its fourth side remaining as a bare surface, disposable on said putting surface and aside said first rubber plate of the angle to expose a selected one of said four sides and thereby providing varying rebounding forces to a golf ball traveling along said putting surface toward said rebound bar.
Claim 8
Dependent Claim
