## Abstract

A golf practice apparatus for simulating sloping ground like the ground of a golf course comprises a table the upper surface of which is covered by a covering such as artificial grass, a supporting member to which the table is pivotally attached disposed along the latitudinal centerline of the underside of the table, and an inclining means wherein a plurality of chains have first ends pivotally attached to the underside of the table at points symmetrical about the supporting member and second ends fixed to a slide device free to move only in the horizontal direction and wherein said chains pass over rollers disposed beneath said points. Using a golf practice apparatus constructed according to the present invention, the kind of sloping ground found on actual golf courses can be simulated, and realistic practice can be done.

## Claims

### Claim 1

A golf practice apparatus comprising a table having an upwardly facing playing surface, a supporting shaft member disposed along the latitudinal centerline of the underside of said table, means for fixedly attaching said table to said shaft member, means journaling said shaft member for pivotal movement, and table-inclining means including a slide device disposed along the underside of the table mounted for slidable movement in a horizontal direction, a plurality of chains have first ends pivotally attached to the underside of the table at connecting points symmetrical about the shaft member and second ends fixed to said slide device, and a roller beneath each of said connecting points for guiding each of said chains.

### Claim 2 (depends on 1)

A golf practice apparatus according to claim 1, including plate-like arms fixing said second ends of said chains and stopper plates pivotally attached to said plate-like arms and connecting said plate-like arms to said slide device.

### Claim 6 (depends on 1)

A golf practice apparatus according to claim 1, including a ball support appropriately positioned on said table, and means for pivotally mounting said ball support with respect to said table such that it is always oriented vertically.

### Claim 7 (depends on 6)

A golf practice apparatus according to claim 6, including an automatic ball feeder connected to the ball support.

### Claim 8 (depends on 1)

A golf practice device according to claim 1 including a covering on said playing surface.

### Claim 9 (depends on 8)

A golf practice device according to claim 8 in which said covering is artificial grass.

### Claim 10 (depends on 1)

A golf practice apparatus according to claim 1, wherein said table is rectangular.
