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. 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.

A connecting buckle for obstacle slackline, comprising slackline connecting buckles, a slackline penetrating opening penetrating from left to right being formed in each connecting buckle; a slackline, sequentially penetrating through slackline penetrating openings of slackline connecting buckles and is used for connecting all slackline connecting buckles; a plurality of same or different types of function module pieces, and each function module piece is detachably installed at bottom of slackline connecting buckle and is connected with the slackline penetrating through slackline connecting buckles. The invention adopts a novel slackline connecting buckle, so that each function module is connected with slackline connecting buckles more quickly, with high strength after connection and improved dismounting efficiency; required activities can be performed on whole device by combining various different function modules to save space layout; after whole slackline is connected, a balanced contact surface is formed at top for balance training.

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.

A disassemblable and height-adjustable frame for slacklines has a slackline support plate which rests on two upwardly converging carriers that are connected to a cross bar at the base by connecting elements. The carriers are rectangular-shaped telescopic tubes. The slackline support plate, which is downwardly open in a U-shape, rests on the upper end of the carriers. The upper end of the front side of the carrier has a convex curved shape on the material side starting from the carrier surface facing the carriers in the operating position, and at the upper end of the rear side of the carrier has a concave curved shape on the material side starting from the surface facing the carriers in the operating position, which merges into a straight line and then forms a convex curve shape.

A slackline device comprising a main body having an underside, 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; a webbing including opposite ends; and a fastening device that fastens each of the opposite ends of the webbing to the underside of the main body adjacent to the two mutually opposite end portions, wherein the webbing in an assembled state of the slackline device being tensioned between the two end portions of the main body with the fastening device configured to distribute load evenly across a width of the webbing.
