Abstract
A leg exercise equipment is disclosed, which includes a base plate, a supporting frame foldably mounted to the base plate, and a crank mechanism. The crank mechanism includes a swinging arm, of which one end is connected with a hydraulic cylinder through a shaft. The other end of the hydraulic cylinder is connected with a connecting pin which is fixedly fastened to the supporting frame. A leg holder is mounted on one end of the swinging arm. When the user's leg exerts force to the leg holder, the force will be transmitted to the hydraulic cylinder to drive the same to move back and forth so as to cause the leg muscle and hip muscle to be exercised evenly.
Claims6
A leg exercise device comprising:
- a base plate allowing a user to stand thereupon;
- a supporting frame mounted on said base plate;
- a crank mechanism including a swinging arm, of which one end having a shaft pivotally connected with said supporting flame;
- said shaft being fixedly mounted with a first connecting rod and a second connecting rod symmetrically;
- each of said connecting rods being connected with a damping device, and the other end of each said damping device being connected with a connecting pin which is fixedly mounted on said supporting frame;
- and
- an adjustable leg holder which includes a connecting member, and said connecting member is connected with said swinging arm in a length-adjustable manner so as to adapt to a user's leg length;
- wherein said connecting member has two elongate slots mounted with two handles respectively in an adjustable manner so as to have the space between said two handles adjusted to adapt a user's leg size;
- whereby the user's leg is able to apply force to said leg holder, which transmits said force to said damping device so as to perform exercise for hip muscle or leg muscle.
A leg exercise device comprising:
- (a) a horizontal base plate, said horizontal base having an area large enough to allow a person to stand thereon;
- (b) a vertical supporting frame foldably mounted on said base plate;
- (c) a crank mechanism including a swinging arm, a shaft, first and second connecting rods, first and second damping cylinders, and a connecting pin, wherein
- (i) said shaft is pivotably mounted on said supporting flame, and said connecting pin is fixedly connected to said supporting frame,
- (ii) said swinging arm and said first and second rods are fixedly connected to said shaft, said first and second rods are connected in a substantially L-shaped manner, and said swinging arm is connected to a joint between said first and second rods,
- (iii) said first and second damping cylinders are connected to said connecting pin at first respective first ends thereof, and said first and second damping cylinders are connected, at second ends thereof, to said first and second rods, respectively,
- (d) an adjustable leg holder connected to said swinging arm via a connecting member in a length-adjustable manner so as to adapt to a user's leg length;
- (e) whereby when the user's leg applies force to said leg holder causing said swinging arm to pivot about said shaft, said force is resisted by said first damping cylinder when said leg moves in an outward direction and by said second damping cylinder when said leg moves in an inward direction, so as to cause a leg muscle or hip muscle to be exercised evenly.
