This invention relates to lattice-like structures,
such as, for examplamusic bar standards, display
stands, frames and like articles of manufacture,
and is concerned more particularly with an im
proved method and means of joining the crossbars of the frame to their transverse supports.

A primary aim of the invention is to obtain
an easily assembled yet‘ ?rm and substantially‘
rigid connection, between the several frame ele»

case of a music bar stand, are uniformly spaced
apart and are disposed alternately along each
side of the‘standard. 'Two‘ of such preformed
elements, when placed‘ in reversed position ad

and the alternated recesses in each being oifs'et
