Abstract
Abstract A golf practice device for simulating uneven lies including a practice platform which is mounted over a base platform for limited universal movement with respect to such base platform. The two platforms are separated by an intermediate member having the shape of a rectangle. A pair of V-shaped connectors extend between and are secured to one pair of opposing sides of the intermediate member and the upper practice platform. A pair of inverted V-shaped connectors extend between and are secured to the other pair of opposing sides of the intermediate member and the base platform. Pivot axes are provided at the junctures of the legs of the V-shaped and inverted V-shaped connectors. Electrical jacks are provided to quickly and easily adjust the tilt of the practice platform to simulate uphill, downhill or sidehill lies. The electrical jacks may be operated by a remote control panel which is connected to electrical circuitry located in a box on the intermediate member.

Claim 1
Independent Claim
80 words
A golf practice device comprising a base platform, a practice platform, an intermediate member, means pivotally connecting opposing sides of said intermediate member in spaced-apart relationship with said practice platform, means pivotally connecting the other opposing sides of said intermediate member in spaced-apart relationship with said base platform, motive means for universally tilting said practice platform with respect to said base platform and locking means for maintaining said practice platform at a selected position with respect to said base platform.
Claim 2
Dependent Claim
80 words
A golf practice device comprising a base platform, a practice platform, an intermediate member, means pivotally connecting opposing sides of said intermediate member in spaced-apart relationship with said practice platform, means pivotally connecting the other opposing sides of said intermediate member in spaced-apart relationship with said base platform, motive means for universally tilting said practice platform with respect to said base platform and locking means for maintaining said practice platform at a selected position with respect to said base platform.
Claim 3
Dependent Claim
28 words
The apparatus of claim 1 further characterized in that the motive means are electrical jacks connected on adjoining sides between the base platform and the said practice platform.
Claim 4
Dependent Claim
