Abstract

A fitness device includes a body, a pedaling unit, a rotating unit, a seat unit, and at least one coupling unit. The coupling unit is pivotally mounted to the base and is coaxially aligned with the axle. The coupling unit is engaged with the rotating unit such that the rotating unit coaxially rotates with the coupling unit for driving the seat unit to convert between a first position in which the seat unit is located away from the base, and a second position in which the seat unit is located proximate to the base. A vertical distance and a horizontal distance between the seat unit and the pedaling unit are altered when converting between the first and second positions. By rotating the rotating unit, the horizontal and vertical distances between the seat and pedaling units are altered for allowing users to exercise in an upright posture or a recumbent posture.

First claim

What is claimed is:

1. A fitness device comprising:
a body having a base, an axle passing through the base defining a longitudinal axis which passes through a center of the axle;
a pedaling unit having two pedals respectively mounted to two ends of the axle;
a rotating unit rotatable around the axis;
a seat unit mounted to the rotating unit;
at least one coupling unit pivotally mounted to the base and coaxially aligned with the axle; wherein the coupling unit includes at least one first coupling member pivotally mounted to the base and coaxially aligned with the longitudinal axis, and wherein the first coupling member is engaged with the rotating unit; and
a handle unit having a turntable member rotatable around the longitudinal axis, and a post outwardly extending from the turntable member, wherein the coupling unit includes at least a second coupling member pivotally mounted to the base, coaxially aligned with the axle, and engaged with the turnable member of the handle unit,
wherein the coupling unit is engaged with the rotating unit such that the rotating unit coaxially rotates with the coupling unit for driving the seat unit and handle unit to convert between a first position in which the seat unit is located away from the base and a second position in which the seat unit is located proximate to the base, wherein a vertical distance and a horizontal distance between the seat unit and the pedaling unit is altered when converting between the first position or the second position, and wherein the fitness device is operable by rotation of the pedals in both positions.

2. A fitness device as claimed in claim 1 , wherein the second coupling member includes a rotatable ring axially disposed along the axis, and a pawl member for securing the rotatable ring with the turnable member.

3. A fitness device as claimed in claim 1 , wherein the rotating unit includes at least one panel engaged with the coupling unit, the at least one panel having a hole axially defined therein and adapted to accommodate the axle, a swing member radially extending outward from the axis for engaging with the coupling unit, the swing member having an extending portion biasedly and outwardly extending therefrom, and wherein the seat unit is mounted to the extending portion.

4. A fitness device as claimed in claim 3 , wherein the rotating unit includes two panels respectively located on two lateral sides of the base, and two coupling units disposed between the two panels, wherein the two first coupling members are respectively engaged to the swing members of the two panels, and the two second coupling members are respectively coupled to opposite sides of the turnable member of the handle unit.

5. A fitness device as claimed in claim 3 , wherein the seat unit includes a frame, a rotating member mounted to a bottom of the frame, and a positioning member engaged with the rotating member, the rotating member having a plurality of notches defined in an outer surface thereof, the positioning member having a fastening member secured between the two extending portions of the two panels, and a bolt disposed on the fastening member for selectively engaging with one of the notches.

6. A fitness device as claimed in claim 1 , wherein the body includes at least one axle sleeve disposed around the axle, and wherein the first coupling member and the second coupling member are respectively and rotatably sleeved on the axle sleeve.

7. A fitness device as claimed in claim 2 , wherein the body includes at least one axle sleeve disposed around the axle, and wherein the first coupling member and the second coupling member are respectively and rotatably sleeved on the axle sleeve.

8. A fitness device as claimed in claim 1 , wherein the second coupling member includes at least one second limiter formed thereon, and the first coupling member includes two first limiters formed thereon and radially located from the axis, wherein the two first limiters are intervally arranged relative to each other such that an included angle is formed between the two first limiters and the axis; and
wherein the second limiter is rotatable with the second coupling member between an idle motion and a linkage motion, such that the second limiter travels within a distance between the two first limiters when in the idle motion, and the second limiter abuts against one of the first limiters for driving the first coupling member to rotate therewith when in the linkage motion.

9. A fitness device as claimed in claim 2 , wherein the second coupling member includes at least one second limiter formed thereon, and the first coupling member includes two first limiters formed thereon and radially located from the axis, wherein the two first limiters are intervally arranged relative to each other such that an included angle is formed between the two first limiters and the axis; and
wherein the second limiter is rotatable with the second coupling member between an idle motion and a linkage motion, such that the second limiter travels within a distance between the two first limiters when in the idle motion, and the second limiter abuts against one of the first limiters for driving the first coupling member to rotate therewith when in the linkage motion.

10. A fitness device as claimed in claim 1 , wherein the coupling unit comprises a first stopper and a second stopper disposed on the base and radially located from the axis, the first and second stoppers intervally arranged relative to each other such that an included angle is formed between the stoppers and the axis, the second coupling member having a first refraining portion and a second refraining portion formed thereon and radially located from the axis such that an included angle is formed therebetween, wherein the first and second stoppers are arranged to respectively block the first refraining portion and the second refraining portion for refraining the second coupling member to rotatably move within a predetermined range.

11. A fitness device as claimed in claim 2 , wherein the coupling unit comprises a first stopper and a second stopper disposed on the base and radially located from the axis, the first and second stoppers intervally arranged relative to each other such that an included angle is formed between the stoppers and the axis, the second coupling member having a first refraining portion and a second refraining portion formed thereon and radially located from the axis such that an included angle is formed therebetween, wherein the first and second stoppers are arranged to respectively block the first refraining portion and the second refraining portion for refraining the second coupling member to rotatably move within a predetermined range.

12. A fitness device as claimed in claim 10 , wherein the first stopper is located at a beginning of the predetermined range, and wherein the second coupling member is at the beginning of the predetermined range when the first refraining portion abuts against the first stopper.

13. A fitness device as claimed in claim 11 , wherein the first stopper is located at a beginning of the predetermined range, and wherein the second coupling member is at the beginning of the predetermined range when the first refraining portion abuts against the first stopper.

14. A fitness device as claimed in claim 12 , wherein the coupling unit has a driving unit, the second refraining portion of the second coupling member being a plug hole, the second stopper having a pin and located at a termination of the predetermined range, and a resilient member disposed on the pin for resiliently urging the pin to engage with the plug hole, and wherein the driving u
