Abstract

The present invention is fitness equipment with multiple functions. The fitness equipment includes a main frame, rotatable head rack, handrail rack, seat set, linkage bar, damping device and a rotatable treadle device. With the coupled configuration of rotatable head rack, seat set, linkage bar and damping device, trampling, hand-pulling and buttock lifting exercises can be achieved. The fitness equipment meets diversified requirements for both horse-riding and trampling, and also saves the space and cost.

Claims

1. A multi-functional fitness apparatus comprising:

a main frame having a frontal and a rear underframe and an upper-frame;

a rotatable head rack having a lower section screwed into a top of said upper frame by a shaft extending downwardly from a bottom of said head rack;

a foot rest positioned at said bottom of said head rack;

a handrail rack mounted onto a top of said head rack;

a seat set having a cushion and a rotatable rack, said seat set having an upright rod positioned at a rear of said rotatable rack, said cushion affixed to said upright rod, said rotatable rack having a bottom screwed into a bottom of said upper frame by another shaft;

a linkage bar linked to said bottom of said rotatable head rack to a front end of said rotatable rack of said seat set;

a damping device mounted between said rotatable rack of said seat set and said main frame such that a resisting force is applied to a downward rotation of said rotatable rack;

a rotatable treadle device mounted into said main frame, said treadle device having a mandrel, a side crank, a treadle and a damper, said underframe comprising a cross-bar and a rotatable wheel rack arranged alternatively on said main frame, said wheel rack having a spanner fixed at a top thereof, said wheel rack having a wheel body at the bottom thereof, said bottom of said wheel rack being rotatable upwardly such that said underframe is grounded tightly by said cross-bar, said wheel rack being rotatable downwardly such that said wheel body is lowered downwardly to a bottom of said crossbar so as to cause said wheel body to be slidable, said bottom of said wheel rack being fastened by a locator.

2. The apparatus of claim 1, said foot rest comprising:

a horizontal support;

a linkage seat;

a rotary extension rod; and

a foot plate, said horizontal support and said linkage seat being fastened tightly by a screw-and-bolt assembly, said rotary extension rod having a coupling end positioned externally at said linkage seat, said foot plate positioned at an extension end of said rotary extension rod.

3. The apparatus of claim 2, said horizontal support and said linkage seat having a sleeve and a spring retained externally thereof, said spring urging said sleeve toward said horizontal support and said linkage seat to cover said linkage seat.

4. The assembly of claim 1, said handrail rack having a curved section at opposite sides thereof, said head rack having a transverse hole at a top thereof for assembly of said handrail rack, said transverse hole having a pair of locators adhered respectively at opposite sides thereof.

5. The assembly of claim 4, the curved section being covered by a flexible coating.

6. The apparatus of claim 1, said locator being a hook-shaped plate screwed into a wheel rack, said hook-shaped plate enabling said plate to be snapped onto a top of said crossbar which said wheel rack rotates downwardly.

7. A multi-functional fitness equipment comprising:

a main frame having a frontal and a rear underframe and an upper-frame;

a rotatable head rack having a lower section screwed into a top of said upper-frame by a shaft extending downwardly from a bottom of said head rack;

a foot rest positioned at said bottom of said head rack;

a handrail rack mounted onto a top of said head rack;

a seat set having a cushion and a rotatable rack, said seat set having an upright rod positioned at a rear of said rotatable rack, said cushion affixed to said upright rod, said rotatable rack having a bottom screwed into a bottom of said upper frame by another shaft;

a linkage bar linked to said bottom of said rotatable head rack to a front end of said rotatable rack of said seat set;

a damping device mounted between said rotatable rack of said seat set and said main frame such that a resisting force is applied to a downward rotation of said rotatable rack;

a rotatable treadle device mounted into said main frame, said treadle device having a mandrel, a side crank, said rotatable rack having a sliding chute mounted at a rear end thereof, said upright rod of said cushion having a linkage tube extending from a front thereof, said linkage tube retractable in said sliding chute, said cushion being flexibly adjustable, a position of said linkage tube in said sliding chute being fixed by a locator.

8. The assembly of claim 7, said locator comprising a rotating handle and a pressing block, said pressing block positioned in an hollow space within said linkage tube, said pressing block being fitted with a bolt hole, said rotating handle having a screw rod extending so as to pass through an elongated hole at one side of said sliding chute and through a punch hole at one side of said linkage tube, said screw rod being screwed into said bolt hole.

9. The assembly of claim 7, said damping device being a retractable pneumatic shaft supporting said rotatable rack.

10. A multi-functional fitness equipment comprising:

a main frame having a frontal and a rear underframe and an upper-frame;

a rotatable head rack having a lower section screwed into a top of said upper-frame by a shaft extending downwardly from a bottom of said head rack;

a foot rest positioned at said bottom of said head rack;

a handrail rack mounted onto a top of said head rack;

a seat set having a cushion and a rotatable rack, said seat set having an upright rod positioned at a rear of said rotatable rack, said cushion affixed to said upright rod, said rotatable rack having a bottom screwed into a bottom of said upper frame by another shaft;

a linkage bar linked to said bottom of said rotatable head rack to a front end of said rotatable rack of said seat set;

a damping device mounted between said rotatable rack of said seat set and said main frame such that a resisting force is applied to a downward rotation of said rotatable rack;

a rotatable treadle device mounted into said main frame, said treadle device having a mandrel, a side crank, said rotatable rack and said upper frame having a support frame mounted therebetween, said support frame having a bottom screwed into said upper frame so as to allow a rotation of a top of said support frame, said top of said support frame having an embedding slot receiving an upright column so as to position both said embedding slot and said rotatable rack.

11. The assembly of claim 10, said upright rod of said rotatable rack having a C-shaped jacket at a top thereof, a convex lug being positioned in a lateral gap so as to adjust a tightness of said C-shaped jacket by a bolt-and-screw cap, said upright rod having a relieving slot at a top thereof so as to allow a passing of said convex lug therethrough, said cushion having a bottom inserted into said C-shaped jacket by a nose bar.

12. The assembly of claim 11, said nose bar having a clamping handle mounted thereto so as to control a lifting of said cushion.
