Abstract

Abstract The hinge enabling articulation of sectional panels (30) on a frame (10) consisting of a lip (11) forming swivel pin, integral with the frame, and at least one retaining member (20), such retaining member being fitted onto a projecting part (12) of the frame and held in place by a flexible blade (23) having a catch thereon which snaps into a groove (13) in the projecting part, each sectional panel (30) terminating at the hinge in a substantially semi-circular trough (31) guided between the lip (11) and a rounded portion (27) of the retaining member (20) located opposite said lip, features a hand releasing tab (25) made integral with the flexible blade (23) and projecting outside the retaining member (20).

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 233 words
A hinge comprising, in combination, a sectional panel, a frame, said frame including a projecting lip of semicircular cross section forming a swivel pin and an integral projecting part extending generally in the same direction as the lip and being spaced therefrom, a sectional panel terminating at one end in a semicircular trough engaging said lip and forming a hinge connection therewith, and at least one retaining member installed on said projecting part, said projecting part including a groove on a face thereof proximate to said lip, said retaining member including a C-shaped lug, enveloping the end of said projecting part, said retaining member including a body having a concave rounded edge abutting said semicircular trough and further including an integral flexible blade extending along a face of said part proximate to said lip and including a catch facing said groove and being snap fitted into said groove by deflection of said flexible blade during engagement of the C-shaped lug with the end of the projecting part of said frame, wherein said flexible blade extends beyond the C-shaped lug, to define a hand releasing tab for forceably deflecting said flexible blade to release said catch from said groove, and wherein said retaining member body is cut out at its center and said flexible blade projects through said cutout from the rounded concave edge of said retaining member body to beyond said C-shaped lug.
