The play system includes a belt having flexible portions and rigid portions that forms an ascending structure around the inside of the support structure such that it ascends from the bottom end of the support structure to the top end of the support structure. The play system includes a plurality of clamps that couple the support structure and the belt. ## Claims ### Claim 1 A play system comprising: a support structure, having a bottom end and a top end, vertically oriented relative to a surface such that the bottom end contacts the surface and the top end is above the surface; a belt assembly having flexible portions and rigid portions that forms an ascending surface inside of the support structure such that it ascends from the bottom end of the support structure to the top end of the support structure, the ascending surface configured to allow users to ascend and descend on; wherein the rigid portions each comprise a plate; and a plurality of clamps that couple the support structure and the belt. ### Claim 2 (depends on 1) The play system of claim 1, wherein the support structure comprising a plurality of poles. ### Claim 3 (depends on 1) The play system of claim 1, further comprising: an inner support structure; and a second plurality of clamps that couple the inner support structure to the belt. ### Claim 4 (depends on 3) The play system of claim 3, wherein the inner support structure comprises a rope structure. ### Claim 5 (depends on 4) The play system of claim 4, wherein the inner support structure comprises a plurality of climbing platforms. ### Claim 6 (depends on 1) The play system of claim 1, wherein each of the flexible portions of the belt assembly comprise a reinforced rubber material. ### Claim 7 (depends on 1) The play system of claim 1, wherein the plate comprises a first steel plate and a second steel plate, wherein the first steel plate couples to a top of the flexible portion and the second steel plate couples to a bottom of the flexible portion. ### Claim 8 (depends on 1) The play system of claim 1, wherein the belt comprises ascending portions and flat portions. ### Claim 9 (depends on 1) The play system of claim 1, further comprising a slide and tunnel that are both coupled to the belt at different heights along the belt. ### Claim 10 A play system comprising: a support structure, having a bottom end and a top end, vertically oriented relative to a surface such that the bottom end contacts the surface and the top end is above the surface; a belt assembly having flexible portions and rigid portions that forms an ascending surface inside of the support structure such that it ascends from the bottom end of the support structure to the top end of the support structure, the ascending surface configured to allow users to ascend and descend on; wherein the rigid portions each comprise a plate and the plates couple at least some of the flexible portions to one another; and a plurality of clamps that couple the support structure and the belt assembly. ### Claim 11 (depends on 10) The play system of claim 10, wherein the first support structure comprises a plurality of poles. ### Claim 12 (depends on 10) The play system of claim 10, further comprising a second support structure that comprises a rope structure on the interior of the belt assembly. ### Claim 13 (depends on 12) The play system of claim 12, where at least one of the plurality of clamps comprises: a belt clamping end configured to couple to an end of one of the plates; and a rope clamping end configured to couple to a rope of the second support structure. ### Claim 14 (depends on 13) The play system of claim 13, wherein the at least one of the plurality of clamps comprises a first fastener configured to tighten the belt clamping end and a second fastener configured to tighten the rope clamping end. ### Claim 15 (depends on 10) The play system of claim 10, wherein at least one of the plates in the plurality of rigid portions comprises: a first set of fasteners configured to couple to a first flexible portion in the belt assembly; and a second set of fasteners configured to couple to a second flexible portion in the belt assembly. ### Claim 16 (depends on 10) The play system of claim 10, wherein the plurality of flexible portions comprise a textured rubber material. ### Claim 17 (depends on 10) The play system of claim 10, wherein the belt path that vertically ascends in a circular shape. ### Claim 18 (depends on 10) The play system of claim 10, wherein the belt ascending surface comprises ascending portions and flat portions. ### Claim 19 A play structure comprising: a support structure comprising a plurality of rigid support poles, the support structure having a bottom end and a top end, vertically oriented relative to a surface such that the bottom end contacts the surface and the top end is above the surface; a plurality of vertical ropes disposed within, and supported, at least in part by, the support structure; a belt assembly having a plurality of flexible portions and a plurality of rigid portions that forms an ascending surface inside of the support structure such that it ascends from the bottom end of the support structure to the top end of the support structure; wherein the plurality of rigid portions comprises a plurality of plates, each plate having a first end coupled to one of the plurality of rigid support poles and a second end coupled to one of the plurality of vertical ropes, the plurality of plates ascending helically around the plurality of vertical ropes; and wherein the plurality of flexible portions comprises a plurality of belts, each belt coupled on a first end to one of the plurality of plates and coupled on a second end to another one of the plurality of plates.
