  • Table with telescopic leg unit
    Patent number: 6581528
    Abstract: A table includes a telescopic leg unit and a positioning mechanism. The telescopic leg unit includes an inner leg post, a tubular outer leg post and a resilient tubular bushing. The positioning mechanism includes a press member, a support member, and an operating lever. The press member is movable in radial inward and radial outward directions relative to the leg unit. The support member is mounted securely on the outer leg post and is formed with a lever coupling hole that is aligned with the press member in a radial direction relative to the leg unit. The operating lever is operable so as to force the press member to move in the radial inward direction and abut against the tubular bushing, thereby enabling the tubular bushing to frictionally engage the inner leg post so as to resist movement of the inner leg post relative to the outer leg post.
