Deployable slackline systems are disclosed which can support a slackline at a desired height and nominal tension. The disclosed systems may maintain one or more slacklines and can adjust height and tension of individual slacklines while the slacklines are in use. The disclosed slackline systems are stowable; tensioning and termination assemblies of the slackline system can each fold into a compact housing having a height substantially less than a vertical range of motion of the slackline. The disclosed slackline systems can be implemented in aquatic or non-aquatic performance environments such as on cruise ships or other hospitality settings.

A trolley apparatus, system, and method of manufacture are described herein. The trolley apparatus may comprise one or more of a first side plate, a second side plate, a support axle, one or more roller components, and/or other components. The support axle may be mounted through and/or between the first side plate and the second side plate. The support axle may be mounted such that the first side plate and the second side plate are at opposite ends of the support axle. The support axle may be configured to support the one or more roller components. In some implementations, the trolley apparatus may be specifically configured to accommodate a slackline webbing which may have a width of about five centimeters.

An apparatus and system whereby a user can move by guidance of a return track on a challenger course. The return track may extend away from the challenge course and overhang its main frame so the user can experience an element outside of the main frame.

The invention relates to a fastening system for a sports and recreation device. The fastening system comprises a slackline, two band clamps, and a block and tackle, and two round slings. The fastening system is characterized in that the band clamps and the block and tackle comprise round-sling bolts and slackline bolts, wherein the round-sling bolts and the slackline bolts can be guided in elongated holes and functional holes vertically with respect to their axes and can be displaced, in the direction of their axes, through cut-outs in the functional holes. The bolts, at each of their two ends, comprise bolt heads having a diameter that is smaller than the cut-outs but larger than the elongated holes.

Balance measurement systems and methods thereof include at least one measurement device or indicator and an unstable or dynamic device or surface or other balance device. In example forms, the at least one measurement device is generally removably mounted to a portion of the body of a user (and/or to a portion of the balance device) such that the movements and body behavior of a user (and/or the balance device) can be measured as the user attempts to balance on the balance device. According to one example form, the unstable device includes a suspended rope or slackline. According to other example forms, the balance device includes a generally unstable platform.

A balance board adapted for riding rail-to-rail, preferably so that at least a portion of a rider's feet will be placed on the board over the elongated roller. The balance board includes an elongated, planar board having a length that exceeds a width. The balance board further includes two pair of stops mounted to an underside of the board, each pair of stops being mounted near opposite ends of the board, and each stop of the pair of stops being mounted near opposite sides of the board. The balance board further includes a traction region between each stop of each pair of stop.

A slackline device comprising a main body having at least one bearing portion and two mutually opposite end portions which are disposed so as to be elevated in relation to the at least one bearing portion, and comprising a webbing which in an assembled state of the slackline device is tensioned between the two end portions of the main body. The slackline device is preferably portable. Strictly speaking, the slackline device disclosed herein is not a slackline in the actual sense, but is a device that is designed to realistically imitate the behavior of a slackline for the user.

The slackline balance board is for use during slacklining It includes an elongated deck having an upper surface and a bottom surface. The deck includes opposite first and second end sections, and a medial cambered section interposed between the first and second end sections. The medial cambered section is arched upwards with reference to a longitudinal axis. Two spaced-apart slackline guides are secured to the bottom surface of the deck.

A slackline device comprising a main body having at least one bearing portion and two mutually opposite end portions which are disposed so as to be elevated in relation to the at least one bearing portion, and comprising a webbing which in an assembled state of the slackline device is tensioned between the two end portions of the main body.
