Abstract
Abstract A knock-down fitting to hold together two panels at right-angles to one another comprises a body having projections extending from one side and a peg which is received in a bore in the body. One end of the peg and each projection of the body has barb formations to engage holes pre-drilled in the panels. In accordance with the invention the other end of the peg received in the bore is toggle-shaped and has a waist engaged on opposite sides by the arms of a bifurcated clip. By acting on the cam surface provided by the waist the clip draws the peg into the bore in the body but the toggle shape of the inner end of the peg allows a degree of lateral tolerance to compensate for minor inaccuracies in the positioning of the holes in the panels.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
267 words
A knock-down fitting assembly for securing together two panels at right-angles to one another, each said panel having pre-drilled hole means therein near to an edge thereof, the assembly comprising a first component comprising a generally oblong body having two flat side surfaces at right-angles to one another, a pair of projections extending generally perpendicularly from one of said two flat sides in mutually spaced relation longitudinally of said side, a bore located generally centrally of said body parallel with said one side and opening to the other of said two sides, and an aperture in the body opening to a third side thereof parallel with said one side and transversely intersecting the bore intermediate the ends of the latter, a second component in the form of a peg having a shoulder intermediate its ends, one end portion of the peg being receivable in the bore in the body until said shoulder abuts said other of said two sides thereof, the other end portion of the peg resembling each said projection of the body, said one end portion of the peg having an hourglass shaped waist, and a third component in the form of a bifurcated clip which is insertable in the aperture so that arms thereof engage opposite sides of the waist in said one end portion of the peg when received in the bore, and by a camming action on the surface of the waist presented to said other end portion of the peg tend to draw the peg into the bore until the shoulder abuts said other of said two sides of the body.

Claim 3
Dependent Claim
38 words
An assembly as claimed in claim 1, wherein each said projection and said other end portion of the peg has along the length thereof a series of barb-shaped projections for frictional engagement in a respective panel hole means.
