Abstract:
A coupling for a connection of two orthogonal unthreaded rods, characterized by:a cylindrical hollow body (1) having an axial hole along a first axis, said body being closed at only one end by an end wall (2) defining at the centre a threaded through hole (2a) and having a semi-cylindrical shaped outer face (2b) having a second axis perpendicular to said first axis;an outer sleeve (3) realized in a single moulding piece with said body (1) and disposed in an off-centre position with respect to said body (1) and defining an axial hole (3a), said axial hole (3a) of said sleeve (3) intersecting said axial hole of said body (1) perpendicularly, thereby creating a slot (4) intercommunicating with the axial holes (2a, 3a) of said hollow body (1) and said sleeve (3);a pair of adjacent cylindrical rollers (5) housed in said hole of said sleeve (3a); anda bolt (6) having a threaded shank (6a) and a shaped head (6b), said rollers (5) being disposed along said threaded shank 6(a);whereby said coupling is adapted to connect the two orthogonal unthreaded rods.
