Abstract
An adjustable golf surface system having first and second platforms pivotally connected via a hinge wherein a golf surface is on the top surface of the first platform, the platforms can rotate about a base and base stud in a clockwise and counterclockwise direction. A lifting mechanism operated by a jackscrew allows the first platform to pivot upwardly with respect to the second platform.

- (d) a first sliding track (410a) disposed in an inner surface (129b) of the third side (113) of the first platform (110) and a second sliding track (410b) disposed in an inner surface (129c) of the third side (123) of the second platform (120);
- (e) a first height adjustment bar (420a) having a first end (421a) and a second end (422a), and a second height adjustment bar (420b) having a first end (421b) and a second end (422b), the second end (422a) of the first height adjustment bar (420a) is pivotally attached to the first end (421b) of the second height adjustment bar (420b) via a first joint (430a), the first end (421a) of the first height adjustment bar (420a) is pivotally attached to the inner surface (129c) of the third side (123) of the second platform (120) wherein the first end (421a) of the first height adjustment bar (420a) is positioned closer to the first side (121) of the second platform (120) than is the second sliding track (410b, the first joint (430a) is slidably disposed in the first sliding track (410a), and the second end (422b) of the second height adjustment bar (420b) is slidably disposed in the second sliding track (410a);
- (f) a third siding track (410c) disposed in an inner surface (129d) of the fourth side (114) of the first platform (110) and a fourth sliding track (410d) disposed in an inner surface (129e) of the fourth side (124) of the second platform (120);
- (g) a third height adjustment bar (420c) having a first end (421c) and a second end (422c), and a fourth height adjustment bar (420d) having a first end (421d) and a second, end (422d), the second end (422c) of the third height adjustment bar (420c) is pivotally attached to the first end (421d) of the fourth height adjustment bar (420d) via a second joint (430b), the first end (421c) of the third height adjustment bar (420c) is pivotally attached to the inner surface (129e) of the fourth side (124) of the second platform (120) wherein the first end (421c) of the third height adjustment bar (420c) is positioned closer to the first side (121) of the second platform (120) than is the fourth sliding track (410d), the second joint (430b) is slidably disposed in the third sliding track (410c), and the second end (422d) of the fourth height adjustment bar (420d) is slidably disposed in the fourth sliding track (410d);
- (h) a first spring line (240a) having a first end (241a) attached to the nut (230) and a second end (242a) attached to the second end (422b) of the second height adjustment bar (420b), and a second spring line (240b) having a first end (241b) attached to the nut (230) and a second end (242b) attached to the second end (422d) of the fourth height adjustment bar (420d);
- (i) a first return spring (250a) anchored to an inner surface (129a) of the second side (122) of the second platform (120) near the third side (123) of the second platform (120), and a second return spring (250b) anchored to the inner surface (129a) of the second side (122) of the platform (120) near the fourth side (124) of the second platform (120);
- and
- (j) a third spring line (240c) connecting the first return spring (250a) to the second end (422b) of the second height adjustment bar (420b) and a fourth spring line (240d) connecting the second return spring (250b to the second end (422d) of the fourth height adjustment bar (420d), the return springs (250) bias to pull the second ends (422) of the second height adjustment bar (420b) and fourth height adjustment bar (420b) toward the second end (122) of the second platform (120);
- wherein when the jackscrew is rotated in a first direction, the nut moves toward the first side (121) of the second platform (120) and the nut pulls the first spring line and third spring line, which causes the second end (422b) of the second height adjustment bar (420b) to slide within the second sliding track (410a) toward the first end (421a) of the first height adjustment bar (420a) and the second end (422d) of the fourth height adjustment bar (420d) to slide within the fourth sliding track (410d) toward the first end (421c) of the third height adjustment bar (420c) causing the first joint (430a) to slide within the first sliding track (410a) and push upwardly on the first platform (110) and the second joint (430b) to slide within the third sliding track (410c) and push upwardly on the first platform (110);
- wherein when the jackscrew is rotated in a second direction, the nut moves away from the first side (121) of the second platform (120) and tension is released from the first spring line and third spring line, and the first return spring (250a) pulls the second end (422b) of the second height adjustment bar (420b) toward the first return spring (250a) and the second return spring (250b) pulls the second end (422d) of the fourth height adjustment bar (420d) toward the second return spring, and the first joint (430a) slides within the first sliding track (410a) and the second joint (430b) slides within the third sliding track (410c), releasing upward pressure on the first platform (110), effectively lowering the height of the first side (111) of the first platform (110).
