  • Telescopically adjustable support particularly for a camera tripod
    Patent number: 4378172
    Abstract: In a telescopically adjustable support, an axially divided elastic sleeve extends over outer and inner tubes and has projections engaging the inner tube through apertures in the outer tube. The sleeve can be tightened to the inner tube by a coupling nut. The radial length of the projections is larger than the radial spacing between the external tube faces so that additional clamping is brought about by the sleeve at a spacing from the sleeve end adjacent the inner tube, whereby clamping is effected at two spaced and separated areas to achieve a particularly rigid connection of the tubes.
