Abstract
An exercise machine applicable for strengthening a user's abdominal muscles is described. The exercise machine can include a base frame having a seat pad, a front leg and a rear leg. The seat pad can be elevated with the front leg and rear legs to provide round support. A mounting assembly may be rotatably mounted on the base frame over the rear leg. The mounting assembly can have at least one pivot joint. A backrest assembly can be movably coupled to the mounting assembly via the at least one pivot joint for swivel movements along the base frame. The backrest assembly can a backrest pad and handle bars. The handle bars can allow a user resting against the backrest pad to control the swivel movements while sitting on the seat pad.
Claims14
An exercising machine comprising:
- a base frame having a seat pad, a front leg and a rear leg, the seat pad elevated with the front leg and the rear leg to provide ground support;
- a mounting assembly rotatably mounted on the base frame over the rear leg via a rotatable structure, the mounting assembly having at least two pivot joints including a front pivot joint and a rear pivot joint, wherein the mounting assembly has a longitudinal direction defined from the front pivot joint to the rear pivot joint, the rotatable structure arranged between the front pivot joint and the rear pivot joint along the longitudinal direction of the mounting assembly, the rotatable structure to allow the mounting assembly to rotate transversely to the front pivot joint;
- and
- a backrest assembly movably coupled to the mounting assembly via the at least two pivot joints for swivel movements along the base frame, the backrest assembly including a backrest pad and handling controls, wherein the handling controls allow a user resting against the backrest pad to control the swivel movements while sitting on the seat pad.
An exercising machine comprising:
- a base frame to provide floor support, the base frame arranged longitudinally between a front side and a rear side, the base frame including a seat pad affixed on top of the base frame;
- and
- a pivoting frame rotatably mounted on the rear side of the base frame, the pivoting frame having a backrest assembly, a mounting assembly and handle bars, the backrest assembly capable of swivel movements along the base frame,
- wherein the backrest assembly has a backrest pad and lever bars, the backrest pad pivotally coupled with the level bars,
- wherein the mounting assembly has more than one rotatable joint including a front pivot joint, a rear pivot joint and a rotatable structure, wherein the mounting assembly has a longitudinal direction defined from the front pivot joint to the rear pivot joint, the rotatable structure arranged between the front pivot joint and the rear pivot joint along the longitudinal direction of the mounting assembly, the backrest pad and the lever bars pivotally coupled with the mounting assembly via the front pivot joint and the rear pivot joint, the base frame engaged with the mounting assembly via the rotatable structure for the rotatable mounting to allow angular relationship between longitudinal directions of the seat pad and the backrest pad,
- wherein handle bars are transversely affixed to the lever bars to allow a user to make push/pull force to cause the swivel movements of the backrest pad, and
- wherein the angular relationship allows twisting effects on the user while exercising with the backrest pad via the swivel moments.
