Abstract:
1. An adjustable golf surface system ( 100 ) comprising: (a) a first platform ( (b) a base ( (c) a jackscrew ( (d) a first sliding track ( (e) a first height adjustment bar ( (f) a third siding track ( (g) a third height adjustment bar ( (h) a first spring line ( (i) a first return spring ( (j) a third spring line ( 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 ( 422 b ) of the second height adjustment bar ( 420 b ) to slide within the second sliding track ( 410 a ) toward the first end ( 421 a ) of the first height adjustment bar ( 420 a ) and the second end ( 422 d ) of the fourth height adjustment bar ( 420 d ) to slide within the fourth sliding track ( 410 d ) toward the first end ( 421 c ) of the third height adjustment bar ( 420 c ) causing the first joint ( 430 a ) to slide within the first sliding track ( 410 a ) and push upwardly on the first platform ( 110 ) and the second joint ( 430 b ) to slide within the third sliding track ( 410 c ) 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 ( 250 a ) pulls the second end ( 422 b ) of the second height adjustment bar ( 420 b ) toward the first return spring ( 250 a ) and the second return spring ( 250 b ) pulls the second end ( 422 d ) of the fourth height adjustment bar ( 420 d ) toward the second return spring, and the first joint ( 430 a ) slides within the first sliding track ( 410 a ) and the second joint ( 430 b ) slides within the third sliding track ( 410 c ), releasing upward pressure on the first platform ( 110 ), effectively lowering the height of the first side ( 111 ) of the first platform ( 110 ).
