Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
230 words
A practice apparatus for hitting a golf ball comprising: a sloping board laid on a floor surface including a sloping base having an upper surface sloping downwardly and frontwardly towards a player and having a ball hole formed in an upper rear portion of the base, a surface mat releasably mounted on said sloping base and having an upper ball hole formed in a rear portion thereof, said ball hole in said mat being in matching communication with said ball hole in said sloping base, a fencing wall formed on rear and side portions of said sloping base and defining a U-shaped sloping channel between said fencing wall and said sloping base for gravitationally rolling a golf ball frontwardly towards a player in said channel, said ball hole of said sloping base having a lateral sloping tunnel communicated with a ball hole and said U-shaped sloping channel for causing a ball entering said hole to gravitationally roll from said ball hole downwardly into said lateral sloping tunnel and into said U-shaped sloping channel, said surface mat being releasably attached by a fixing bolt secured to said sloping base whereby said surface mat can be repositioned to change said upper ball hole either on an upper portion or a lower portion of said base for practice putting to cause a ball to roll on an upward or a downward sloping surface.
Claim 2
Dependent Claim
230 words
A practice apparatus for hitting a golf ball comprising: a sloping board laid on a floor surface including a sloping base having an upper surface sloping downwardly and frontwardly towards a player and having a ball hole formed in an upper rear portion of the base, a surface mat releasably mounted on said sloping base and having an upper ball hole formed in a rear portion thereof, said ball hole in said mat being in matching communication with said ball hole in said sloping base, a fencing wall formed on rear and side portions of said sloping base and defining a U-shaped sloping channel between said fencing wall and said sloping base for gravitationally rolling a golf ball frontwardly towards a player in said channel, said ball hole of said sloping base having a lateral sloping tunnel communicated with a ball hole and said U-shaped sloping channel for causing a ball entering said hole to gravitationally roll from said ball hole downwardly into said lateral sloping tunnel and into said U-shaped sloping channel, said surface mat being releasably attached by a fixing bolt secured to said sloping base whereby said surface mat can be repositioned to change said upper ball hole either on an upper portion or a lower portion of said base for practice putting to cause a ball to roll on an upward or a downward sloping surface.
Claim 3
Dependent Claim
88 words
A practice apparatus according to claim 8, wherein said surface mat is formed with a bottom extension on a central bottom portion thereof and engageable with a recess portion formed in the sloping base, said fixing bolt being rotatably secured in the recess portion of said sloping base and being insertable into the bottom extension of the surface mat for releasably attaching the mat on the sloping base, a spring being disposed on the fixing bolt and a nut retained on a lower end of the fixing bolt.
Claim 4
Dependent Claim
44 words
A practice apparatus according to claim 1, wherein said sloping board includes two inclination adjusters respectively attached to a rear right side portion and a rear left side portion of said board for adjusting the inclination of said board either sloping rightwardly or leftwardly.
Claim 5
Dependent Claim
162 words
A practice apparatus according to claim 3, wherein each said inclination adjuster includes: a supporting leg pivotally mounted at one of its ends to a rear side portion of the sloping board, a restoring spring for biasing said leg in a predetermined direction, a protrusion attached to the other end of said leg and protruding sidewardly from a bottom edge of the fencing wall of said board, said protrusion serving as a handle for manual pivoting of the leg for adjusting the height or inclination of the board, a plurality of ratchet teeth tapered towards a board support surface and formed on a rear portion of said one end of said leg, a pawl resiliently engageable with the ratchet teeth for allowing manual pivoting of the leg towards the board support surface and for locking the ratchet teeth to prevent a counter rotation of the leg, a recess formed in each side of said fencing wall for receiving a respective pivoted leg.
Claim 6
Dependent Claim
61 words
A practice apparatus according to claim 4, wherein said pawl is urged by a spring to engage the ratchet teeth, a releasing rod protruding outwardly from the pawl through an arcuate wall slot formed in the fencing wall, the releasing rod being manually pulled to disengage the pawl from the ratchet teeth so as to retract the leg into said recess.
