Abstract

The outer and inner tubes (1,2) of a telescopic prop are connected by a thread (17) engaged to an outer adjustment nut (3) with handles (26,27). A sliding sleeve (15) on the upper tube (2) bears on the collar (25) of the nut (3) and includes diametrically opposite notches (5) with intermediate inclined steps (9). An axial travel limit pin (10) through the upper tube rests on the inclined steps when the prop is extended and load carrying. In this situation the notches (8) are closed by tongues (12) on a sliding collar (11). For quick release, the collar is lifted by a handle (14) and the sleeve tapped round to allow the pin to drop into the notches.
