Abstract
Abstract A golf putting practice board includes a slope-adjusting plate fixed on a biasing stick having a block member secured on a lower portion of the stick, and a socket member formed on a sloping base portion for universally engaging the block member to allow the slope-adjusting plate to be angularly, universally and adjustably mounted on the sloping base portion of the practice board having a surface mat covering the base portion, so that upon an optional adjustment of the slope-adjusting plate universally built in the base portion under the surface mat, a plurality of sloping surfaces of the practice board can be adjustably obtained to simulate an actual putting green to enhance a player's skill for practicing a sliced line, a hooked line or a curved line tracked by a golf ball.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
342 words
A golf putting practice apparatus comprising: a sloping board having a base portion formed on a central portion of the board having an upper sloping surface tapered frontwardly formed on the base portion, a ball hole recessed in a rear portion of said base portion, and a central recess portion recessed in a central portion of said base portion beyond said ball hole; a slope-adjusting means formed in said central recess portion in said base portion; and a surface mat covering said base portion and said slope-adjusting means; said slope-adjusting means being angularly adjustably mounted on said base portion, so that upon a golfer manually pushing said slope-adjusting means by acting a mat portion corresponding to said slope-adjusting means positioned under said mat, a slope of the mat will be adjusted to simulate a sloping surface of an actual golf course for practice purpose; said slope-adjusting means including a slope-adjusting member universally mounted on a universal supporting means formed in a central portion of said central recess portion of said base portion; said universal supporting means including: a biasing stick fixed into a fixing hole formed in a bottom portion of the slope-adjusting member, a generally spherically shaped block member secured with the biasing stick, a generally spherically shaped socket member defining a hollow portion in said central recess portion and universally coupling the block member therein, a lower plate secured with the socket member, and a tensioning spring resiliently tensioning the block member in the socket member, said universal supporting means fixed in a holder means formed in a central portion of said central recess portion of the base portion; and said block member including an enlarged lower portion having a diameter larger than a diameter of an upper socket opening of the socket member to ensure a coupling of the block member with the socket member, and an upper stem formed in the block member for retaining an upper end of a tensioning spring of which a lower end is retained on a lower stem formed on the lower plate.
Claim 2
Dependent Claim
342 words
A golf putting practice apparatus comprising: a sloping board having a base portion formed on a central portion of the board having an upper sloping surface tapered frontwardly formed on the base portion, a ball hole recessed in a rear portion of said base portion, and a central recess portion recessed in a central portion of said base portion beyond said ball hole; a slope-adjusting means formed in said central recess portion in said base portion; and a surface mat covering said base portion and said slope-adjusting means; said slope-adjusting means being angularly adjustably mounted on said base portion, so that upon a golfer manually pushing said slope-adjusting means by acting a mat portion corresponding to said slope-adjusting means positioned under said mat, a slope of the mat will be adjusted to simulate a sloping surface of an actual golf course for practice purpose; said slope-adjusting means including a slope-adjusting member universally mounted on a universal supporting means formed in a central portion of said central recess portion of said base portion; said universal supporting means including: a biasing stick fixed into a fixing hole formed in a bottom portion of the slope-adjusting member, a generally spherically shaped block member secured with the biasing stick, a generally spherically shaped socket member defining a hollow portion in said central recess portion and universally coupling the block member therein, a lower plate secured with the socket member, and a tensioning spring resiliently tensioning the block member in the socket member, said universal supporting means fixed in a holder means formed in a central portion of said central recess portion of the base portion; and said block member including an enlarged lower portion having a diameter larger than a diameter of an upper socket opening of the socket member to ensure a coupling of the block member with the socket member, and an upper stem formed in the block member for retaining an upper end of a tensioning spring of which a lower end is retained on a lower stem formed on the lower plate.
Claim 3
Dependent Claim
62 words
A golf putting practice apparatus according to claim 1, wherein said lower plate of said universal supporting means is combinably secured with a lower flange formed on a lower portion of the socket member and is fixed into the holder means of said base portion having a bottom tip of said holder means protruding downwardly to be laid on a floor surface.
Claim 4
Dependent Claim
44 words
A golf putting practice apparatus according to claim 1, wherein said slope-adjusting member is formed with a fixing hole eccentric to a center or a gravity center of said slope-adjusting member to be engageably fixed on said biasing stick of said universal supporting means.
