FLEXIBLE FIXED NODE OF A FOLDING STRUCTURE Russian patent published in 2019 - IPC E04H15/48 

FIELD: sports equipment.

SUBSTANCE: invention relates to folding frame-tent structures, namely, to their folding units, and can be used as an element of camping equipment (for example, tents for tourists, fishermen, hunters), technical equipment for field operations (for example, frame structures for welders, cable splicers and other technical workers), commercial equipment (for example, concession stands) and other shelters. Technical result is achieved by the fact that the flexible fixed node of a folding structure contains two supporting rods, while at the end of each rod a hollow nozzle is installed, ends of the flexible coupling element are installed limitedly movable in the cavity of the nozzles in the direction of the corresponding rod, and on the outer surface of each nozzle there are positioning bushings, while the unit is provided with an external movable element between the positioning bushings and the sleeve surrounding it and the bushings, as well as a position fixator of the external movable element on the sleeve.

EFFECT: technical result is the creation of a flexible fixed node of a folding structure with the possibility of its full fixation in the opened state and the possibility of mutually coaxial rotation of its supporting rods in the unlatched state.
