Portable golf practice device
First Claim
1. A portable golf practice device for simulating the response of natural turf when impacted by the head of a golf club during a golf swing, the device comprising:
- a base member having spaced-apart longitudinal sides defining an operating space therebetween;
a carriage tray slidably positioned on the base member for forward and rearward movement in the operating space between the longitudinal sides;
a simulated turf surface on the carriage tray; and
a carriage retraction mechanism comprising;
a guide portion comprising a guide member on each of the spaced-apart longitudinal sides of the base member having a guide direction aligned with the forward and rearward movement of the carriage tray and a guided member on each side of the carriage tray slidingly engaged with the guide member on that side of the base member for allowing the carriage tray to guidedly slide forward and rearward; and
a retraction portion comprising a biasing element on each of the spaced-apart longitudinal sides connected between the base member and the carriage tray having a substantially unbiased condition when the carriage tray is in a ready-to-use position on the base member and being biased into an energy-stored condition when the carriage tray has been moved forward;
whereby upon being hit by a golf club during a swing the carriage tray will slide forward, the biasing elements will obtain energy as a restoring force and become biased, and will return the carriage tray to the ready-to-use condition and the biasing elements to a substantially unbiased condition.

Abstract
A portable golf practice device is disclosed that is easily transported by the golfer and simulates the response of natural turf when impacted by the club head during a golf swing. The device includes a base extension, which can be unfolded and slid under a platform on which the golfer stands, for maintaining stability during use. The device includes a simulated turf surface fitted in a tray. The tray rests on a base member. When a golf ball placed on the simulated turf surface is struck by a golf club, the tray and the simulated turf surface are driven forward. Means are provided to return the tray and the simulated turf surface to their original position. In its travel configuration the device folds into a compact form similar to a slim briefcase
