ASSEMBLY OF PARTS CONNECTION Russian patent published in 2014 - IPC F16B5/07 

FIELD: construction.

SUBSTANCE: assembly of parts connection comprises ledges made on coupled sides of parts, having bulb-shaped expansions at the ends and necks at their bases, and slots that respond to the ledges, representing bulb-shaped grooves that match bulb-shaped expansions of ledges changing into bores corresponding to journals of ledges. Surfaces of ends of ledges and coupled surfaces of slots bottom have conical shape, and tops of surfaces of ledges ends and slots bottom are located at different sides relative to connected parts. Side surfaces of ledges and coupled side surfaces of slots are formed by movement of a straight line along a guide that represents a line of crossing of a spherical surface with a cylindrical surface, formed by movement of a straight line along an S-shaped guide. Side surfaces of ledges and side surfaces of slots are smoothly coupled, accordingly, with surfaces of ends of ledges and surfaces of slots bottom.

EFFECT: development of an assembly of parts connection limited by surfaces of curvilinear shape.
