Abstract
Abstract A golf shot practice apparatus with a flat base, a flat support board disposed over said base having a simulated turf towards one end thereof and a step mat towards the other end thereof. Interposed between the base and support board is a universal mechanism including a support cylinder extending upward from the base, a curved plate shaped like the lower portion of a sphere disposed between said support cylinder and the support board under the step mat. The curved plate engages the support board under the step mat. Engaging the inside of said curved plate is a disc affixed to an axial rod. Coupled to the rod are control elements to lift the rod and disc to alter the altitude in space of the curved plate so as to incline the support board at any angle desired with flixing elements including fixing inner and outer cylinders engaging the fixing rod and lowering the rod so the disc engages the curved plate in a desired position. Coupled to the fixing elements is a handle and alarm elements operatively responsive to the position of the handle to provide an alarm when the support board is not fixed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
225 words
A golf shot practicing apparatus comprising: a. a base; b. a support board above said base for a person to have golf ball hitting practice having thereon a part on which a ball will be placed and a part allowing the player to take a stance toward the ball; c. universal means by which the practice board above said base will be freely supported in any inclination in any direction and at any angle, said universal means including a support cylinder which is fixed to said base and a spherical plate which has a shape of the lower part of a hollow sphere and which is disposed upon the said support cylinder, while the peripheral rim thereof is fixed to the lower side of the said support board; and, d. fixing means for said support board to fix the position thereof in a horizontal or inclined state inside the said spherical plate including a disc that presses the spherical plate to the upper side of the said supporting cylinder and a controlling device having a fixing cylinder that has a threaded inner periphery, a rotary elevating part that grapples with said fixing cylinder, a handle to rotate it and a tightening rod which passes through said spherical plate that connects said elevating part and the disc for pressing the spherical plate to said fixing cylinder.

Claim 10
Dependent Claim
217 words
A golf shot practice apparatus comprising in combination: a. a flat base (1) b. a flat support board (2) disposed over said base having a simulated turf (28) towards one end thereof and a step mat (37) towards the other end thereof; c. a universal mechanism (3) interposed between said base (1) and said support board (2) including a support cylinder (46) extending upward from said base (1), a curved plate (47) shaped like the lower portion of a sphere disposed between said cylinder (46) and said support board (2) under said step mat, said curved plate engaging said support board substantially under said step mat, a disc (50) for engaging the inside of said curved plate affixed to an axial rod (58) control means coupled to said rod (58) to lift said rod and disc to alter the altitude in space of said curved plate to incline said support board at any angle desired with fixing means including a fixing inner and outer cylinders (53, 55) engaging said fixing rod and lowering said rod so said disc engages said curved plate in a desired position, a handle (57) coupled to said fixing means and alarm means (83) operatively responsive to the position of said handle to provide an alarm when said support board is not fixed.
Claim 11
Dependent Claim
217 words
A golf shot practice apparatus comprising in combination: a. a flat base (1) b. a flat support board (2) disposed over said base having a simulated turf (28) towards one end thereof and a step mat (37) towards the other end thereof; c. a universal mechanism (3) interposed between said base (1) and said support board (2) including a support cylinder (46) extending upward from said base (1), a curved plate (47) shaped like the lower portion of a sphere disposed between said cylinder (46) and said support board (2) under said step mat, said curved plate engaging said support board substantially under said step mat, a disc (50) for engaging the inside of said curved plate affixed to an axial rod (58) control means coupled to said rod (58) to lift said rod and disc to alter the altitude in space of said curved plate to incline said support board at any angle desired with fixing means including a fixing inner and outer cylinders (53, 55) engaging said fixing rod and lowering said rod so said disc engages said curved plate in a desired position, a handle (57) coupled to said fixing means and alarm means (83) operatively responsive to the position of said handle to provide an alarm when said support board is not fixed.
