Abstract

An arm exercising device includes a frame, a linkage mechanism, and an impeding unit disposed to apply a resistance force to the linkage mechanism. The frame includes an upright support that has a fixed guide rod. The linkage mechanism includes a pair of swing arms pivotally mounted on the upright support for swinging upward and downward, a runner sleeve disposed slidably over the guide rod for movement upward or downward, a pair of linking rods, each connected between the runner sleeve and one of the swing arms, and a force transmitting cord connected to the handgrips and the swing arms. The resistance force applied to each arm of the user who grips both handgrips and pulls downward is applied evenly to enable a smooth exercise to be performed.

Claims

1. An arm exercising device comprising:

a frame including an upright support that has a fixed guide rod; and

a linkage mechanism including

a pair of swing arms pivotally mounted on said upright support for swinging upward and downward,

a runner sleeve disposed slidably over said guide rod for movement upward or downward,

a pair of linking rods, each connected between said runner sleeve and one of said swing arms,

a pair of handgrips, and

a force transmitting cord connected to said handgrips and said swing arms.

2. The arm exercising device according to claim 1, wherein said guide rod extends in a vertical direction, said runner sleeve having a pair of connectors that are respectively disposed on two opposite sides of said runner sleeve and that are respectively connected to said linking rods.

3. The arm exercising device according to claim 2, wherein each of said linking rods has one end connected pivotally to one of said connectors and the other end connected pivotally to one of said swing arms.

4. The arm exercising device according to claim 3, wherein each of said swing arms has a first end connected pivotally to said upright support, a second end extending away from said upright support, and a swing arm pulley attached to said second end, said force transmitting cord passing over said swing arm pulley, said other end of each of said linking rods being connected pivotally to one of said swing arms between said first and second ends.

5. The arm exercising device according to claim 4, further comprising an impeding unit disposed to apply a resistance force to said linkage mechanism.

6. The arm exercising device according to claim 5, wherein said impeding unit includes a helical spring that is sleeved on said guide rod and that has one end abutting against said runner sleeve.

7. The arm exercising device according to claim 5, wherein said impeding unit includes a fluid pressure actuated telescopic mechanism that has one end fixed to said upright support and the other end connected to said runner sleeve.

8. The arm exercising device according to claim 5, wherein said impeding unit includes a plurality of elastic straps each connected between one of said linking rods and one of said swing arms.

9. The arm exercising device according to claim 5, wherein said impeding unit includes a plurality of elastic straps each connected between said upright support and one of said swing arms.

10. The arm exercising device according to claim 4, wherein said frame includes a base connected to a bottom end of said upright support, and a transverse bar mounted transversely on said upright support,

said arm exercising device further comprising:

two upper pulleys mounted on two ends of said transverse bar;

two lower pulleys mounted on said base; and

a middle pulley mounted on said bottom end of said upright support;

said force transmitting cord having two cord ends which respectively connect said handgrips, said force transmitting cord consecutively passing over one of said upper pulleys, one of said lower pulleys, one of said swing arm pulleys, said middle pulley, the other one of said swing arm pulleys, the other one of said lower pulleys, and the other one of said upper pulleys.

11. The arm exercising device according to claim 10, wherein said transverse bar has a plurality of lugs, and said upper pulleys are hung on two selected ones of said lugs.
