Orbital elements have been derived for four dwarf M stars in the Gliese catalogue: Gl 319, Gl 570 B, Gl 735, and Gl 815. All except Gl 319 are members of chromospherically active systems. Values of v sin i have been determined for some of the components. Gl 319 appears now as a quadruple system and may contain the first detected non active dM binary star, with an orbital period as low as 21 days. Gl 570 A is also the bright star HR 5568 whose visual secondary appears double-lined with a mass ratio of 0.71±0.02, and which could be resolved with speckle interferometry. Gl 735 is a new double-lined spectroscopic binary. Gl 815 is resolved for the first time into a triple-lined spectroscopy binary, which permits the determination of preliminary elements for the outer astrometric orbit with P = 29.3 yr. Two systems (Gl 319 AC and Gl 570 AB) are found to be very likely bound.
