ABSTRACT:
Improvements for slidably mounting a size-adjustable luggage cart handle inverter U-shape in a lower U-shape, consisting of each leg of the upper U-shape being disposed through a hole in a cap covering the opening of the lower U-shape and having an integrally molded hub with a threaded bore to thereby increase the number of teeth threadably engaging the threaded member which bears against the upper U-shape in any selected position of its sliding movement, which determines the size of the handle, and thus obviate thread-stripping, wobble and other such defects.
