Abstract
A locking mechanism for a first leg member telescopically received within a second leg member, including first and second clamps longitudinally fixed with respect to the second leg member. The second leg member has an opening which exposes a biasing surface of the first clamp and that surface engages a cam surface pivotable about an axis fixed to the second leg member, the cam surface thereby operable to bias the first and second clamps together to engage the first leg member.
