A swing chair includes: a support which is installed at a certain height or more above the floor; a main operation member elongated and having a virtual first rotation axis provided to the support at one side thereof and rotatably coupled to the support; a sub operation member elongated and having a virtual second rotation axis, provided to the support at one side thereof and spaced parallel to the first rotation axis, and rotatably coupled to the support; a seat portion coupled to any one of the main operation member and the sub operation member; and a rotation connecting member elongated and arranged in a front-rear direction and having a rear portion that is rotatably coupled to the other side of the main operation member and a front portion that is rotatably coupled to the other side of the sub operation member.

A bracket for a play structure includes a first flange and a second flange. The first flange includes a proximal end and a distal end. The first flange extends along a plane. The second flange extends from the first flange at the proximal end such that the second flange is disposed on one side of the plane. The pair of side flanges extend from the first flange such that the pair of side flanges are disposed on an opposite side of the plane as the second flange.

An exercise apparatus for attachment and use within a door frame includes a pair of elongated frame elements with each having apertures configured to receive various types of cross bars. The frame elements are designed to be secured to vertical portions of a door frame without interfering with passing through the doorway or closing the door. A cross bar having a length greater than the door width is configured to be received within corresponding apertures among the frame elements. A cross bar has a retractable spring pin protruding from the bar so that the spring pin may engage a frame element to limit axial excursion of the bar. Two such spring pins may be included in the bar, so that with the frame elements including apertures having pin-receiving pockets, one type of bar may rotate freely while another type of bar is prevented from rotation.

A playground swing that allows the caregiver to sit within a supportive swing seat while the small child sits on the caregiver's lap while facing the caregiver with their legs wrapped around the hips of the caregiver. The caregiver's legs are free to hand from the swing seat allowing them to pump their legs to provide a swinging motion to the swing while the child's back is supported by a backrest opposing the caregiver's seat allowing the caregiver's arms and hands to be free to interact.

A zip line includes a substantially rigid track supported above a ground surface by a plurality of supports, a trolley which moves along the track, and a rider support suspended from the trolley. The track is comprised of a plurality of track segments connected together such that adjacent track segments have substantially no freedom of movement relative to each other, and such that adjacent track segments present a substantially smooth, continuous, and uninterrupted surface. The track includes a run and a flange extending upwardly from the run. The trolley comprises a frame having upper wheel mounts to which first and second upper wheels are rotatably mounted. The first upper wheels are oriented such that they engage an upper surface of the track run and the second upper wheels are oriented such that they will engage the track flange upon rotational movement of the trolley relative the track run.

The invention provides means, methods, and devices for suspending persons and goods above the ground while outdoors. Particularly, the invention provides a treepod assembly having a tent and a suspension element, capable of securely supporting at least one occupant while suspended above the ground from a tree or other elevated structure. In some embodiments, the treepod assembly may further include a rigid frame for additional support. Certain embodiments include an inflatable pocket that protects occupants and items inside the tent from injury or damage in case of a fall and impact with the ground.

Implementations of a training rig are provided. In some implementations, the training rig comprises a first strip of material having a first loop on a first end of the first strip of material and a plurality of openings positioned along the length of the first strip of material. In some implementations, the first strip of material is used with a tie-down ratchet system to secure the first strip of material between a pair of trees sufficiently high enough so that a user can swing from hanging objects secured to the first strip of material. Hanging objects are attached to the first strip of material using the openings in the first strip of material. In another implementation, a wire having formed along its length loops using the wire are secured between a pair of trees using chains, a turnbuckle, and a carabiner. Hanging objects are attached to the wire using the openings formed by the loops.
