Document Type and Number:
WIPO Patent Application WO/2014/178754
Kind Code:
A8
Abstract:
The invention relates to detachable connections of parts, primarily rigid parts, and can be used, in particular, for connecting elements of building structures. The unit for connecting parts with a curvilinear surface comprises protrusions which are formed on those sides of the parts which are to be joined, said protrusions having bulb-like enlargements at the ends and necks at the bases thereof, and grooves which are complementary to the protrusions and constitute bulb-like recesses corresponding to the bulb-like enlargements of the protrusions and merging into cavities corresponding to the necks of the protrusions. The surfaces of the ends of the protrusions and adjoining surfaces of the bottom of the grooves have a conical shape, and the vertices of the surfaces of the ends of the protrusions and of the bottom of the grooves are arranged along different sides relative to the parts to be connected, the lateral surfaces of the protrusions and adjoining lateral surfaces of the grooves are formed by moving a straight line along a guide, which constitutes an intersecting line of a spherical surface with a cylindrical surface formed by moving the straight line along an S-like guide. The lateral surfaces of the protrusions and the lateral surfaces of the grooves are smoothly joined to the surfaces of the ends of the protrusions and surfaces of the bottom of the grooves, respectively.
