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 simulated turf surface fitted in a carriage tray. The carriage tray is supported on a retraction assembly on which it can slide forward and back, and which has springs that will retract it after it has moved forward. The retraction assembly is supported on a base member. In use, when the turf surface is hit by a golf club it moves forward simulating the feel of actual turf, and then returns to its ready to use position.

Claims

1. A golf practice device for simulating the response of natural turf when impacted by the head of a golf club during a golf swing, said device comprising;

a base member adapted to support a carriage retraction assembly on each of longitudinal sides;

a carriage tray positioned above said base member and having at least one sleeve on each of longitudinal sides to slidingly engage a carriage retraction assembly;

a simulated turf surface on said carriage tray;

a carriage retraction assembly supported on each of the longitudinal sides of said base member and being slidingly engaged with said at least one sleeve for controlling sliding forward in the general direction of ball flight and retraction of said carriage tray and said simulated turf surface when said simulated surface is impacted by the head of a golf club striking a golf ball placed on said simulated turf surface.

2. The golf practice device of claim 1 wherein said carriage retraction assembly comprises;

a guide rail supported on said base member and said at least one sleeve on each of said longitudinal sides of said carriage tray is slidingly mounted on said respective guide rail on each of said longitudinal sides of said base member; and

one or multiple forward compression springs, said one or multiple forward compression springs being fitted over said guide rail and said one or more forward compression springs being forward of said at least one sleeve such that forward movement and retraction of said carriage tray are controlled by said carriage retraction assembly.

3. The golf practice device of claim 2 wherein each of said carriage retraction assemblies further comprise one or multiple compression springs on said guide rail rearward of said at least one sleeve thereby to control the positioning of said carriage tray upon retraction to a ready to use position.

4. The golf practice device of claim 3 wherein each of said carriage retraction assemblies is carried in a rail housing on each side of said base member, said rail housing having a slot and said at least one sleeve extends from said carriage tray through said slot and onto said guide rail.

5. The golf practice device of claim 3 wherein said carriage retraction assembly on each side is carried on said base member by a forward support member and a rearward support member on which said guide rail is held at forward and rearward ends thereof respectively.

6. The golf practice device of claim 3 wherein said at least one sleeve is a plurality of sleeves separated longitudinally and attached to said carriage tray and slidingly mounted on said guide rail.

7. The golf practice device of claim 5 wherein said forward support member and said rearward support member are tabs bent up from said base member and having means to retain said forward and rearward ends of said guide rails.

8. The golf practice device of claim 5 further comprising at least one low friction strip on said base member, having a low friction surface facing said carriage tray.

9. The golf practice device of claim 5 wherein said at least one sleeve is a first sleeve and a second sleeve separated longitudinally and attached to said carriage tray and slidingly mounted on said guide rail

10. The golf practice device of claim 6 further comprising a base extension hingedly attached to a longitudinal side of said base member and having a first, closed position covering said carriage tray and a second, open position coplanar with said base member,

whereby in said first closed position the golf practice device is contained in a package defined by said base extension and said base member and in said second, open position said base extension can be used to stabilize said device and for installing under a mat.

11. The golf practice device of claim 10 further comprising a latch interengageable between said base extension and said base member to retain said base extension in said first, closed position.

12. The golf practice device of claim 10 wherein said base extension comprises one or multiple extension plates connected by hinge means such that said base extension can be unfolded and slid under a mat to stabilize said device in use and can be folded for transporting said device.

13. A golf practice device for simulating the response of natural turf when impacted by the head of a golf club during a golf swing, said device comprising:

a base member having a pair of spaced apart parallel housings extending along a length dimension;

a carriage tray having one or more sleeves affixed to both sides along the length dimension slidably positioned on said parallel housings of said base member;

a simulated turf surface fixed to said carriage tray; and

carriage retraction means arranged on both sides of said carriage tray along the length dimension and fitted in said rail housings for controlling the sliding forward in the general direction of the ball flight and the retraction of said carriage tray and said simulated turf surface when said simulated turf surface is impacted by the head of a golf club striking a golf ball placed on said simulated turf surface.

14. The golf practice device of claim 13 wherein each said carriage retraction means further comprises a guide rail, and one or multiple forward compression springs said one or multiple forward compression springs and said sleeve being fitted over said guide rail with said one or more forward compression springs being forward of said sleeve-such that forward movement and retraction of said carriage tray are controlled by said carriage retraction means.

15. The golf practice device of claim 13 further comprising a base extension connected to said base member.

16. The golf practice device of claim 14 wherein said carriage retraction means further comprises an energy absorbing element rearward of the carriage tray for limiting the retraction movement of the carriage tray.

17. The golf practice device of claim 15 wherein said base extension further comprises one or multiple extension plates connected by hinge means such that said base extension can be unfolded and slid under said platform to stabilize said device when in use and can be folded under said base member for transport or storage.

18. The golf practice device of claim 16 wherein said energy absorbing element comprises one or multiple compression springs on each of said guide rails rearward of said sleeves.

19. A golf practice device comprising;

a base member adapted to support a carriage assembly comprising support members on spaced apart longitudinal sides thereof, said support members having on each of said sides a forward support member and a rearward support member, said forward and rearward support members being longitudinally aligned;

a carriage assembly comprising a carriage tray and a carriage retraction assembly on each longitudinal side thereof;

said carriage tray being positioned above said base member;

at least one sleeve on each of longitudinal sides of said carriage tray;

a simulated turf surface on said carriage tray;

said carriage retraction assemblies comprising;

a guide rail on each side of said device extending longitudinally from and supported by said forward and rearward support members respectively, said at least one sleeve on each side being slidingly supported on the respective guide rail on each side;

one or multiple forward compression springs being fitted over each of said guide rails between said at least one sleeve and said forward support member on each side such that forward movement and retraction of said carriage tray are controlled by said carriage retraction assembly.

20. The golf practice device of claim 19 wherein said carriage retraction assembly further comprises one or multiple compression springs on said guide rail rearward of said at least one sleeve thereby to control the positioning of said carriage tray upon retraction to a ready to use position.

21. The golf practice device of claim 20 wherein said at least one sleeve is a plurality of sleeves separated longitudinally and attached to said carriage tray and slidingly mounted on said guide rail.
