## Abstract

A climbing structure includes a support frame and a wall assembly. The wall assembly comprises a chain arranged as a loop with an array of climbing panels attached to the chain so as to maintain a configuration that rotates the climbing panels downward as the user climbs to achieve a continuous climbing experience. A lower shaft assembly includes a shaft that rotates based on an angle of the wall assembly. A sprocket is mounted to the shaft such that the shaft and the sprocket rotate independently to maintain tension on the chain as the climbing panels rotate downward. A cable hub assembly is rigidly attached to the shaft and secures a cable that is attached to the support frame. A disc braking system includes a disc rigidly attached to the shaft and a caliper mounted on bearing bolts such that the disc braking system fixes the angle of the wall assembly without affecting the continuous climbing experience.

## Claims

### Claim 1

A climbing structure comprising:
a) a support frame;
b) a wall assembly comprising a chain arranged as a loop with an array of climbing panels attached to the chain so as to maintain a configuration that rotates the climbing panels downward as the user climbs to achieve a continuous climbing experience; and
c) a lower shaft assembly comprising:
1) a shaft that rotates based on an angle of the wall assembly;
2) a sprocket that maintains tension on the chain as the climbing panels rotate downward, the sprocket being mounted to the shaft such that the shaft and the sprocket rotate independently;
3) a cable hub assembly rigidly attached to the shaft and securing a cable that is attached to the support frame; and
4) a disc braking system comprising a disc rigidly attached to the shaft and a caliper mounted on bearing bolts such that the disc braking system fixes the angle of the wall assembly without affecting the continuous climbing experience.

### Claim 2 (depends on 1)

The climbing structure of claim 1 wherein the wall assembly is attached to the support frame at a pivot point that is proximate to and behind the center of gravity of the wall assembly.

### Claim 3 (depends on 1)

The climbing structure of claim 1 wherein wall assembly is configured to have an angular range that is from 10 degrees to −35 degrees.

### Claim 4 (depends on 1)

The climbing structure of claim 1 wherein wall assembly is configured to have an angular range that is from 10 degrees to −20 degrees.

### Claim 5 (depends on 1)

The climbing structure of claim 1 wherein the support structure comprises a curved front support leg.

### Claim 6 (depends on 1)

The climbing structure of claim 1 wherein the cable hub assembly comprises a central disc with a cut-out.

### Claim 7 (depends on 6)

The climbing structure of claim 6 wherein the cable is secured in the cable hub assembly using the cut-out.

### Claim 8 (depends on 1)

The climbing structure of claim 1 wherein the cable hub assembly comprises a hub with a three-degree taper.

### Claim 9 (depends on 1)

The climbing structure of claim 1 wherein the climbing panels are less than or equal to four feet wide.

### Claim 10 (depends on 1)

The climbing structure of claim 1 wherein the climbing panels are less than or equal to six feet wide.
