摘要： A support assembly for a tree-based platform includes a rod having a length greater than a diameter of a tree to which the platform is intended to be attached. The assembly further includes a first ring defining an opening configured to receive a portion of a tree, and a first plurality of extending members inwardly advanceable relative to the first ring. Each of the extending members has an end portion configured to engage the tree in the opening of the first ring when sufficiently advanced. The assembly further includes a second ring defining an opening configured to receive a portion of the tree, and a second plurality of extending members inwardly advanceable relative to the second ring. Each extending member has an end portion configured to engage the tree in the opening of the second ring when sufficiently advanced. The assembly further includes first and second supports. Each support has a bottom rail, a top rail, and two side rails. The top rails of the first and second support are configured to be coupled to the second ring, and the bottom rails of the first and second supports are configured to be coupled to the first ring. The assembly further includes a first tension element configured to couple to the rod and the bottom rail of the first support, and a second tension element configured to couple to the rod and the bottom rail of the second support.
