ABSTRACT:
A bistable element enables control of an adjustable member, e.g. an adjustable leg, by selectively positioning an engaging element that can selectively prevent retraction. Preferably, the bistable element enables control in two regimes by positioning an engaging piece that can bear on the adjustable member. In one stable configuration, the bistable element enables a first regime, by positioning an engaging piece to frictionally bear upon the adjustable member to prevent retraction but enable free extension so that once the device is adjusted for a given support surface, the article is positively locked against tipping even if the load on the article is shifted. In another stable configuration, the bistable element enables a second regime by positioning the engaging piece such that the adjustable member is freely retractable and extendible so that the mechanism can be readjusted when the article is moved to a different surface.
