Abstract

A climbing machine includes a resistance device, a driving device, and two climbing devices. The driving device comprises an upper wheel set, an axial wheel set, and a lower wheel set. The axial wheel set includes a first axial wheel and a second axial wheel. Through a plurality of connecting members, the alternate up and down movements of the climbing device drive the upper wheel set and the lower wheel set to rotate in a first direction, the upper wheel set drives the first axial wheel to rotate in a second direction, and the lower wheel set drives the second axial wheel to rotate in the first direction.

First claim

What is claimed is:

1. A climbing machine, comprising:
a support frame comprising two uprights;
two climbing devices coupling the two uprights, each of the two climbing device comprising a sliding tube for moving up and down along the corresponding upright;
a resistance device comprising an axle for providing a resistance for the two climbing devices;
a driving device, comprising:
an axial wheel set comprising a first axial wheel and a second axial wheel, wherein the first axial wheel and the second axial wheel are pivotally coupled to the axle and are rotated independently to each other, and each of the first axial wheel and the second axial wheel comprises a one-way bearing;
an upper wheel set disposed above the axial wheel set;
a lower wheel set disposed below the axial wheel set;
a first transmission member connecting the sliding tubes of the two climbing devices, the upper wheel set, and the first axial wheel;
a second transmission member connecting the sliding tubes of the two climbing devices and the lower wheel set;
a third transmission member connecting the second axial wheel and the lower wheel set;

whereby the alternate up and down movements of the sliding tube of the two climbing devices cause the upper wheel set and the lower wheel set to rotate in a first direction, the first axial wheel to rotate in a second direction, and the second axial wheel to rotate in the first direction.

2. The climbing machine as recited in claim 1 , wherein the upper wheel set comprises a first sprocket and a second sprocket, the lower wheel set comprises a third sprocket and a fourth sprocket, and wherein the third sprocket is a double sprocket comprising a sprocket A and a sprocket B, the first transmission member, the second transmission member, and the third transmission member are chains, and the first axial wheel and the second axial wheel are sprockets.

3. The climbing machine as recited in claim 2 , wherein the first transmission member engages with the first sprocket, the second sprocket, and the first axial wheel and includes two ends coupled with the two sliding tubes of the two climbing devices, the second transmission member engages with the sprocket A of the third sprocket and the fourth sprocket and includes two ends coupled with the two sliding tubes of the two climbing devices, and the third transmission member engages with the sprocket B of the third sprocket and the second axial wheel.

4. The climbing machine as recited in claim 1 , wherein each of the two climbing devices further comprises a pedal and a pedal support, the sliding tube is movably disposed within the upright, a portion of the pedal support is movably disposed within a slot of the upright, and the pedal connects to the pedal support.

5. The climbing machine as recited in claim 1 , wherein each of the two climbing devices further comprises a plurality of adjusting wheel sets, and each of the plurality of adjusting wheel sets comprises a plurality of fixed wheels configured to abut an outer surface of the sliding tube.

6. The climbing machine as recited in claim 5 , wherein each adjusting wheel set comprises:
two fixed wheels being pivotally mounted on a fixing seat at a side of the upright and being in contact with an outer surface of the sliding tube;
two adjusting wheels being disposed on the upright opposite to the two fixed wheels; and
an adjusting device coupling to the two adjusting wheels for adjusting tightness between the two adjusting wheels and the sliding tube.

7. The climbing machine as recited in claim 6 , wherein the adjusting device comprises:
an adjusting member being pivotally mounted on a raised structure protruded from a surface of the upright; and
an adjusting bolt passing through a first end of the adjusting member and connecting to the upright,
the two adjusting wheels being pivotally mounted on a left side and a right side of a second end of the adjusting member and abutting against the outer surface of the sliding tube.

8. The climbing machine as recited in claim 1 , wherein the resistance device further comprises:
a driving wheel having the axle; and
a flywheel coupling to the driving wheel via a connecting member.
