Exercise device
An exercise device comprises a frame having a front end and a back end, a carriage that rolls between the front end and the back end of the frame, a jump board assembly having a jump board rotatably attached to a jump board frame, and at least one hinge that permits the jump board frame to rotate between a stowed position beneath the carriage and a deployed position above the carriage. When the jump board frame is in the stowed position, the carriage rolls above the jump board assembly without interference.
1 . An exercise device comprising:
a frame having a front end and a back end;
a carriage that rolls between the front end and the back end of the frame;
a jump board assembly having a jump board rotatably attached to a jump board frame; and
at least one hinge that permits the jump board frame to rotate between a stowed position beneath the carriage and a deployed position above the carriage,
wherein when the jump board frame is in the stowed position, the carriage rolls above the jump board assembly without interference.
2 . The exercise device according to claim 1 , further comprising a rotation lock mechanism that permits locking of an orientation of the jump board relative to the frame.
3 . The exercise device according to claim 1 , wherein the jump board is rotatably mounted to the jump board frame through a frame board.
4 . The exercise device according to claim 3 , wherein the frame board is firmly attached to the jump board frame.
5 . The exercise device according to claim 3 , wherein the jump board rotates on the frame board about a pivot, and wherein the exercise device further comprises a pull pin, positioned apart from the pivot, that selectively locks an orientation of the jump board relative to the frame board.
6 . The exercise device according to claim 5 , wherein the pull pin inserts into either of two holes in the jump board.
7 . The exercise device according to claim 6 , wherein the two holes are at zero and ninety degrees.
8 . The exercise device according to claim 1 , wherein the jump board assembly also includes a rotation locking plate.
9 . The exercise device according to claim 8 , wherein the rotation locking plate is attached to the jump board.
10 . The exercise device according to claim 8 , wherein the rotation locking plate includes an arced slot that receives a guide pin for limiting rotation of the jump board to a predetermined angle.
11 . The exercise device according to claim 10 , wherein the predetermined angle is ninety degrees.
12 . The exercise device according to claim 10 , wherein the jump board rotates on a frame board that is attached to the jump board frame, and wherein the guide pin extends from the frame board.
13 . The exercise device according to claim 1 , wherein the jump board rotates on a frame board that is attached to the jump board frame, and wherein a pull pin is mounted on the frame board and includes a pin that inserts into one of two holes in the jump board.
14 . The exercise device according to claim 1 , when in a fully deployed position the jump board is rotated ninety degrees relative to the stowed position.
15 . The exercise device according to claim 14 , wherein the jump board is rectangular.
16 . The exercise device according to claim 15 , wherein when in an initially deployed position, the longer sides of the jump board are oriented vertically, and when in the fully deployed position, the longer sides of the jump board are parallel to a horizontal support surface.
17 . The exercise device according to claim 14 , wherein in the stowed position the jump board is substantially parallel with the carriage, and in the fully deployed position the jump board is substantially planar perpendicular with the carriage.
18 . The exercise device according to claim 1 , further comprising a footbar and a front platform, and wherein the footbar is tilted down and the front platform is tilted up prior to rotating the jump board frame from the stowed position to the deployed position.
19 . The exercise device according to claim 1 , further comprising a pair of roller catches that are configured to deflect outwardly against an inward spring bias when the jump board frame rotates up, initially pushing the pair of roller catches outwardly and then selectively holding the jump board frame until sufficient force is applied to the jump board frame to overcome the inward spring bias in the pair of roller catches in order to return the jump board frame to the stowed position.
20 . The exercise device according to claim 1 , wherein the jump board assembly also includes a handle for lifting the jump board.
