Abstract

An exercise apparatus includes a seat and a movement mechanism located in front of the seat, the movement mechanism has two pedals for the user to step on with both feet respectively. During exercise, the middle portion of each pedal cyclically displaces along a predetermined pedal exercise path based on the guidance of the movement mechanism. Additionally, an elevation angle of the toe end relative to the heel end gradually increases and decreases in a cycle period. The predetermined pedal exercise path includes a highest position, a lowest position, a frontmost position, a rearmost position, a maximum elevation position, and a minimum elevation position. The maximum elevation position is located within a path from the highest position to the lowest position, passing through the frontmost position. Similarly, the minimum elevation position is located within path from the lowest position to the highest position, passing through the rearmost position.

Dependent claims

A recumbent exercise apparatus that allows a user to perform leg exercises in a seated position, comprising:

a frame;
a seat disposed on the frame to support the user's buttocks in a fixed position;
and
a movement mechanism movably arranged on the frame and has a left pedal and a right pedal located in front of the seat for the user to step on with both feet respectively, each pedal having a toe end, a heel end, and a middle portion located between the toe end and the heel end;
when performing the leg exercise, the middle portion of each pedal cyclically displaces relative to the frame along a predetermined pedal exercise path based on the guidance of the movement mechanism, and an elevation angle between the toe end and the heel end cyclically changes in a predetermined manner;
wherein the predetermined pedal exercise path is located on a vertical plane defined by vertical and longitudinal directions of the frame, the predetermined pedal exercise path has a major axis with a relatively higher front end and a relatively lower rear end, and having a highest position, a lowest position, a frontmost position, a rearmost position, a maximum elevation position and a minimum elevation position;
wherein the maximum elevation position is located within a path from the highest position to the lowest position while passing through the frontmost position, and the minimum elevation position is located within a path from the lowest position to the highest position while passing through the rearmost position;
wherein the toe end of each pedal remains higher than the heel end;
during the middle portion moving from the maximum elevation position to the minimum elevation position along the predetermined pedal exercise path, the elevation angle of the toe end relative to the heel end decreases gradually;
and during the middle portion moving from the minimum elevation position to the maximum elevation position along the predetermined pedal exercise path, the elevation angle of the toe end relative to the heel end increases gradually.

A recumbent exercise apparatus that allows a user to perform leg exercises in a seated position, comprising:

a frame having a front portion;
a seat located behind the front portion of the frame to support the user's buttocks in a fixed position;
and
a movement mechanism movably mounted at the front portion of the frame, including a left first connecting rod, a right first connecting rod, a left second connecting rod, a right second connecting rod, a left pedal and a right pedal, wherein:
each first connecting rod comprises a surrounding portion, a first reciprocating portion and a first pivoting portion, the surrounding portion is restricted to moving along a circular path relative to the frame, and the first reciprocating portion is restricted to moving along a first reciprocating path relative to the frame;
each second connecting rod comprises a second reciprocating portion and a second pivoting portion, the second reciprocating portion is restricted to moving along a second reciprocating path relative to the frame, and the second pivoting portion is pivotally connected to the first pivoting portion of the corresponding first connecting rod;
when the surrounding portions of the first connecting rods rotate one circle along the circular path, the first reciprocating portions of the first connecting rods and the second reciprocating portions of the second connecting rods reciprocate once along the first reciprocating path and the second reciprocating path respectively, and the first pivoting portions of the first connecting rods and the second pivoting portions of the second connecting rods rotate one circle along a closed path, and an angular change of each second connecting rod is smaller than that of each first connecting rod;
the left and right pedals are respectively mounted on the left and right second connecting rods for the user to step on with both feet respectively;
each pedal has a toe end, a heel end, and a middle portion located between the toe end and heel end;
when performing the leg exercise, the middle portion of each pedal cyclically displaces relative to the frame along a predetermined pedal exercise path based on the guidance of the movement mechanism;
and an elevation angle between the toe end and the heel end cyclically changes in a predetermined manner;
the toe end of each pedal remains higher than the heel end.
