Abstract (en)
[origin: US4626005A] A fluid-tight flexible connection comprises couplings (27, 28) of soft elastic material, inserted in cavities (11) of hollow sections (12, 13), flexible parts (29) of soft elastic material arranged between the couplings, nipples (32) of hard material inserted in passages (33) of the couplings (27, 28) and in transverse passages (34) of the flexible parts (29), the nipples having barbs (40, 41) exerting an expanding action, and having an internal bore (39). The nipples (32) provide a fluid-tight connection between the several parts, namely the hollow sections (12, 13), the coupling parts (27, 28) and the flexible parts (29), which connection has a comparatively high tensile strength in the direction of the cavities (11) by virtue of the barbs. The adjoining hollow sections (12, 13) can hinge relative to each other owing to the elasticity of the flexible part (29), the maximum hinge angle being determined by the elasticity of the flexible part (29) and its length.
