Abstract

Abstract 1,208,232. Corner connectors for panel frames. ACME GENERAL CORP. 6 Feb., 1969 [10 May, 1968], No. 6594/69. Heading E1J. In a panel frame corner connection the stile 10 has a transverse section of E shape consisting of an inner flange 37, outer flange 38 and a springy middle flange 39 to accommodate panels 15 of different thicknesses, said connector comprising an L-shaped springy metal member 20 having one rectangular arm 22 with a side wall 28 perpendicular thereto and along one longitudinal edge thereof, the side wall 28 having cut out therefrom a longitudinally extending resilient arm 30 with a detent 31 on its free end adapted to engage in an opening 33 in the stile, the other arm of the member 20 forming a hook with a diverging end portion 23 bevelled at its extreme end portion 25, to engage in a hole 27 in a flange of the rail to draw the rail towards the stile The weight of the door on the detent 31 retains it in the aperture 33 and when pressed back to release the connector from the stile, a stop 32 prevents over stressing of the arm 30 A projection 34 on the arm 28 prevents the connector being pushed too far into the stile and spacer lumps 35 retain the arm 30 as correct distance from the outer flange 38 and are guided in the stile by end of the flange 39.
