A portable ice shelter comprises a base, a rigid frame member, a multi-panel skin and a first set of flexible poles. The base comprises a bottom wall and a sidewall that forms an outer perimeter. The rigid frame member is pivotably mounted to the base at first and second locations, and is moveable between a stored position against the base and a deployed position. angled from the base. The multi-panel skin is coupled to the rigid frame member, the multi-panel skin defining an enclosure when expanded. The first set of flexible poles extend from the rigid frame member, and each of the flexible poles in the first set is connected in an expandable fashion so as to expand at least a portion of the multi-panel skin when the rigid frame member is in the deployed position.

Self-locking bi-foldable load bearing segments are disclosed that can be used in applications such as ladders or ramp. First and second sections of the segment are foldably coupled to transition between an open configuration and a folded configuration. The first and second sections can include rungs pivotally attached to rails that can be further transitioned from the folded configuration to a collapsed configuration, but not transitioned from the open configuration to the collapsed configuration. Openings in the side walls of the rails allow the rungs to pivot in one direction, but not an opposite direction. In the open configuration, the openings of the first and second sections may be oriented opposite, and the direction of allowed rotation of the rungs of the first section and second section are opposite, restricting compression of the rails together. In the folded configuration, the openings of the first and second sections can be oriented the same to allow rotation of the rungs and compression of the rails together.

Tree stands are disclosed for providing an elevated standing location. The tree stand can include a support post, a seat rotatably coupled to the first end of the support post, and a platform rotatably coupled to the second end of the support post. The platform can comprise a plurality interconnected polygonal shapes defining a top standing surface. The platform can be a grating that has load bearing properties and that can be cast from a mold. The platform includes a perimeter wall, a surface portion, and one or more reinforcement walls. A height or thickness of the surface portion is less than a height or thickness of the perimeter wall and/or the reinforcement walls.
