FIELD: sports; games. ^ SUBSTANCE: assemble joint contains connected parts and connecting elements. Connected parts are round with through round-section apertures, and connecting element consists of one rod piece, one end forked piece and one end socket piece. Rod piece is tubular and round-section, thus wall of its upper part is provided with longitudinal elongated slots forming petals. On internal surface of each one there is a flange. On external surface of rod piece lower part there is designed annular relieved portion with section similar to section of flange on petal internal surface. End forked and socket details consist of tubular fragments with round section similar to section of upper part of rod piece. The greatest cross-section dimension dc of rod piece is within do<dc<1,1 do, where do is the greatest cross-section dimension of through aperture section. ^ EFFECT: assembly joint provides fixed demountable connection of two and more solid round parts with equal external surface without flanges. ^ 4 cl, 24 dwg |
