A play structure having one or more monolith structures for the connection of other surfaces (e.g., deckings, water-based elements, interactive elements, etc.). Each of the monolith structures may be adjustably connected with a ground surface such that a variety of possible angles may be obtained by the monolith whit respect to the ground surface. After the desired orientation of the monolith is obtained to the ground surface via the adjustable connection, the monolith may be secured in such position. Water or fluid may be provided to the monolith structures via piping that interfaces with the monolith structures by a fluid connection that is in communication with piping disposed within the monolith structures. A fluid damping or delivery system (e.g., based upon a tipping element that provides water to a fluid flowing surface and/or other water diversion element) may be provided as part of be play structure.

The zip line rail system can be connected to a challenge course, a zip line, a zip track system, or any combination thereof. The zip line rail system of the present invention can have two rails that a member slide's two wheels rollably engage with, and the zip line rail system can be configured in any of a variety of directions.

A system for controlling use of an exercise course by a person in a climbing park has a guiding element, which extends along a longitudinal direction and along which a person can move between a connecting section of the guiding element and a disconnecting section of the guiding element. A securing device is movably attachable along the guiding element between the connecting section and the disconnecting section. The securing device is connectable to the guiding element in the connecting section and is disconnectable from the guiding element in the disconnecting section. An identification device is configured such that, by the identification device, at least a connecting of the securing device within the identification section is identifiable, such that an occupancy of the guiding element with another person is identifiable therewith. An actuating device of the securing device is controllable with the identification device, such that the actuating device of the securing device is adjustable in a clearance position and, upon identification of the occupancy of the guiding element by another person, in a blocking mode. The actuating device of the securing device is coupled with the securing device, such that, in the blocking mode, a connecting of the securing device in the connecting section and/or a displacing of the securing device along the guiding element is blocked.

Emergency egress systems carry multiple riders simultaneously accessing a zip line (catenary) from higher, accessible, working locations to lower, safer areas in a marine environment. Hangers above the track line suspend trolleys to avoid weighting the catenary unduly at the high end, which might otherwise alter (reduce) clearance distances and safety of riders above a launch platform (deck). Catenary shape is controlled against approaching the launch deck by sequencing the release from the hangers of each trolley to roll along the catenary with its own rider. Track line systems installed may be left undeployed indefinitely. Deployment of a track line will typically be fully effected at the time of egress, adding time but eliminating permanent obstructions that would result if a permanent deployment of track lines were undertaken. Terminal ends are anchored and configured to accommodate workers arriving after escape.

An auto reset zip line assembly comprising a cable running along the circumference of two pulleys that are spaced apart forming a closed loop is provided. A pair of rigid frames are fixedly coupled to the cable at an equal distance from each other. The pulley includes a wheel having a rim that has a continuous trough along the circumference to retain the cable. The wheel is rotatably mounted on a shaft and the shaft is mounted to a hosing. The pulleys include a mechanism to suspend a zip line assembly between two vertical supports. The auto reset zip line assembly further comprises a braking mechanism and a pair of guarding plates coupled to the housing to prevent derailing and entangling of the cable. The invention is advantageous by providing a safe zip line assembly that obviated the need of returning a trolley to the starting point of the zip line.

Described herein are latching devices where relative speed of movement between members is in part controlled or reduced via eddy current formation and in part controlled or relative motion stopped via a latch arrangement. Various embodiments are described, one being use of a conductive member; at least one magnetic field and a latch member that, prior to latching, moves independently to the at least one conductive member. A kinematic relationship exists between the conductive member and at least one magnetic field that enables the conductive member to move at a different speed relative to the magnetic field on application of an energizing force, thereby inducing an eddy current drag force by relative movement of the conductive member in the magnetic field. The eddy current drag force resulting causes movement of the conductive member causing the conductive member to engage the latch member thereby halting movement between the at least one conductive member and the at least one latch member.
