Abstract

A universal fitness machine includes an upright frame formed of a base and a post, a swivel arm mechanism, which has a transverse bar fastened to the top end of the post and two cantilever units respectively rotatably connected to the two distal ends of the transverse bar, each cantilever unit having an elastic rope that has an inner end connected to the respective cantilever unit and an outer end extending to the free end of the respective cantilever and mounted with a grip, a lifter, which has a slide coupled to the post, a seat pad affixed to the front side of the slide and two handles fastened to two opposite lateral sides of the seat pad. By means of pulling the elastic rope or lifting the lifter, the universal fitness machine is used for multiple weight-training exercises.

Claims

1. A universal fitness machine, comprising:

an upright frame, said upright frame comprising a post, said post having a top end and a bottom end opposing the top end, and a base affixed to the bottom end of said post;

a swivel arm mechanism, said swivel arm mechanism comprising a transverse bar fastened to the top end of said post and two cantilever units respectively rotatably connected to two distal ends of said transverse bar, each said cantilever unit having at least one first elastic rope mounted therein, each said first elastic rope having an inner end connected to the respective cantilever unit and an outer end extending to the free end of the respective cantilever and mounted with a respective grip; and

a lifter, said lifter comprising a slide coupled to and movable up and down along said post, a seat pad affixed to a front side of said slide and two handles respectively fastened to two opposite lateral sides of said seat pad.

2. The universal fitness machine as claimed in claim 1, further comprising a support frame for supporting said upright frame in vertical on a flat surface, said support frame comprising a floor plate for positioning on a flat surface, said floor plate having tow upright lugs located on a top wall thereof, a strut connected between said post and said floor plate, said strut having a top end, a bottom end opposite to said top end and two lugs respectively bilaterally extended from the top end, a first pivot member fastened to the lugs of said strut to pivotally connect the top end of said strut to said post, a second pivot member fastened to the upright lugs of said floor plate and the bottom end of said strut to pivotally connect said floor plate to said strut, and a lock pin insertable through the upright lugs of said floor plate and the bottom end of said strut to lock said strut and said floor plate.

3. The universal fitness machine as claimed in claim 1, wherein said swivel arm mechanism further comprises two axles respectively perpendicularly extended from the two distal ends of said transverse bar, and an axle sleeve fixedly provided at the fixed end of each of said cantilever units and respectively coupled to said axles.

4. The universal fitness machine as claimed in claim 3, wherein said swivel arm mechanism further comprises two graduated discs respectively fixedly mounted on said axles at the two distal ends of said transverse bar, each said graduated disc having a plurality of positioning holes spaced from one another at different angles, and a lock pin movably mounted in the fixed end of each of said cantilever units and selectively insertable into one positioning hole of one said graduated disc to lock the associating cantilever unit to said transverse bar, and a spring member loaded on the lock pin at the fixed end of each of said cantilever units and adapted for forcing the associating lock pin into one positioning hole of the associating graduated disc.

5. The universal fitness machine as claimed in claim 1, wherein each said cantilever unit further comprises a long tube and a wheel holder, said long tube having a fixed end and a free end, said wheel holder comprising a connection tube connected to the free end of said long tube, two locating frames extended from the periphery of said connection tube in a parallel manner, at least one first pulley pivotally mounted in between the two locating frames, and an end cover covered on said connection tube and said two locating frames at a bottom side;

each first elastic rope of each cantilever unit has the inner end thereof inserted into the inside of the long tube of the associating cantilever unit and affixed to the fixed end of the long tube and the outer end thereof wound round the at least one first pulley and connected to the associating grip.

6. The universal fitness machine as claimed in claim 5, wherein the long tube of each said cantilever unit has two locating frames fixedly located on the fixed end thereof in a parallel manner and at least one second pulley pivotally arranged between the two locating frames at the fixed end thereof;

the inner end of each first elastic rope of each said cantilever unit is wound round the at least one second pulley of the associating cantilever unit and then fastened to the fixed end of the long tube of the associating cantilever unit.

7. The universal fitness machine as claimed in claim 1, wherein said slide of said lifter is formed of a channel bar slidably coupled to said post, having a plurality of rollers mounted on top and bottom sides thereof and kept in contact with front and back sides of said post.

8. The universal fitness machine as claimed in claim 1, wherein said lifter further comprises two lugs forwardly extended from a bottom side of said slide, a seat bar fixedly mounted on a bottom side of said seat pad and fixedly connected with said handles, a pivot member transversely fastened to said seat bar and said slide to pivotally connect said seat bar to said slide, and a lock pin insertable through said slide and said seat bar to lock said seat bar and said slide.

9. The universal fitness machine as claimed in claim 1, further comprising two first hangers fixedly mounted on said base of said upright frame at two opposite sides relative to said post, two second hangers fixedly mounted on said transverse bar of said swivel arm mechanism at two opposite sides relative to said post, two third hangers fixedly mounted on said slide at two opposite lateral sides, and a plurality of second elastic ropes selectively connectable between said first hangers and said third hangers or between said second hangers and said third hangers.

10. The universal fitness machine as claimed in claim 9, wherein said lifter further comprises a back pad fixedly mounted on said slide, and a fourth hanger fixedly mounted on a back side of said back pad.
