## Abstract

A putting green assembly, the assembly comprising a playing mat, a ball cup and a combination means for adjusting the topography of the green and for returning a plurality of balls, the combination means being adapted to elevate at least one flattened area of the playing mat and create an incline therein, the incline changing the topography of the playing mat and further causing the plurality of balls to move away from the incline of the playing mat.

## Claims

### Claim 1

A putting green assembly, said assembly comprising a playing mat, a target hole in said playing mat, a means for adjusting the topography of said mat and for returning any balls on said mat to a predetermined location on said assembly, said means being adapted to elevate a predetermined segment of said playing mat and thereby adjust said topography of said mat by creating an incline therein, said incline also causing any balls on said predetermined segment to move away from said incline of said playing mat, control means for automatically operating said topography adjusting and ball return means, and detector means responsive to the presence of a ball on either said predetermined segment of said playing mat or in said target hole for signalling said control means to operate said topography adjusting and to operate said ball return means.

### Claim 2

A putting green assembly, said assembly comprising a playing mat, said playing mat being fixed at an end and being movable at another end, said assembly further including at least one ball return opening adjacent said playing mat movable end and remote from said fixed end, means extending from said opening to said fixed end for returning balls entering said opening to said fixed end of said playing mat; a target hole in said playing mat remote from said fixed end; and a means for adjusting the topography of said playing mat and for returning a plurality of balls on said playing mat through said ball return opening to said fixed end of said mat, said adjusting means including a plurality of actuator that are selectively located at different locations beneath said playing mat for selectively elevating said playing mat and thereby adjusting said topography by creating a plurality of inclines therein, said inclines also causing balls on said playing mat remote from said fixed end to move towards said ball return opening of said mat wherein said plurality of balls are returned to said attached fixed end of said mat.

### Claim 3 (depends on 2)

The putting green assembly of claim 2 further comprising control means for automatically operating said topography adjusting and ball return means, and first detection means responsive to the presence of at least one ball on said movable end of said playing mat for signalling said control means to operate said topography adjusting and ball return means.

### Claim 4 (depends on 3)

The putting green assembly of claim 3 further comprising a second detector means responsive to the presence of at least one ball in said target hole for signalling said control means to operate said topography adjusting and ball return means.
