US Patent 10080412 Telescopic handle for piece of luggage

A telescopic handle for a piece of luggage has telescoping inner and outer tubes. A rod fixed on the outer tube has a toothed lower end, a toothed upper end spaced above the toothed lower end, and an untoothed sliding section between the upper and lower ends. The outer end of the inner tube carries a grip and the outer tube is fixed in the piece of luggage. A handle on the grip can be actuated to shift a locking element in the inner tube between a locking position engaging the upper or lower end of the rod of the outer tube and preventing relative movement of the inner and outer tubes and a freeing position permitting such movement.
