Tab and slot connector means

Abstract

A first structural frame member (11) has two tabs (15) projecting from one end and may be secured to a second structural frame member (21) having two slots (25) piercing it intermediate its ends by insertion of the tabs through the respective slots N"Z and subsequent deformation of the tabs to prevent their withdrawal from the slots. Each tab tapers from a tab base (15A) to a tab tip (15B) which is narrower than the tab base, and each slot is defined by two opposed, short, end faces (26) and two opposed, elongate "Z side faces, said side faces comprising opposed center parts (27), each at least as long as the width of the tab tip, and opposed flanking parts (28) on either side of the center parts extending from the center parts to the respective end faces. The spacing between said center parts is greater than the lengths of the end faces, whereby, in use, the tab tips can be inserted freely into the slots notwithstanding some misalignment therebetween and, on continued insertion, the tabs are guided by flanking parts into alignment with the opposed end faces for snug accommodation of the tab base therebetween.

Dependencies are inferred from the claim text.
