Abstract
Abstract A plug for a panel aperture comprising a plate portion and a plurality of resilient legs which depend from the plate portion and which are shaped to be snap-engagable through the aperture in the panel so that the plate portion is drawn onto the panel thereby at least substantially closing the aperture, wherein the legs are formed by extensions of the plate portion which have been folded back onto the plate portion and then away from the plate portion, whereby the legs project from the plate portion from a position radially inwardly of the periphery of the plate portion leaving the periphery of the plate portion unbroken. The folded portion of each leg is preferably located in a recess in the plate portion so as to lie flush with the undersurface of the plate portion and a sealing member may be provided on the undersurface of the periphery of the plate portion. The sealing member may be a heat softenable plastics material which will harden when heated and cooled to bond the plate portion to the panel in which the plug is mounted.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
222 words
A one-piece plug for a panel aperture comprising a plate member having a flat, planar inside face portion, a peripheral edge and a plurality of resilient legs which depend from said plate member from the inside face portion side thereof adjacent said peripheral edge, said plate member having a plurality of spaced recesses embossed on the inside face thereof and adjacent each leg and said peripheral edge, said legs being formed by extensions of the plate member, each leg having: a first portion integrally joined to said peripheral edge which is folded back onto the inside face portion of said plate member and is positioned within said recesses and abutting the bottom of said recesses so as to lie substantially flush with and substantially in coplanar relationship with the said inside face portion of said plate member, each of said recesses having a width substantially equal to said first portions of said legs, a second portion which extends substantially at right angles to said plate member, and a third portion extending from said second portion, said third portion including a retaining part and an inwardly inclined lead-in part, said second and third portions of each of said legs projecting from the plate member at a position radially inwardly of said peripheral edge thereby leaving said peripheral edge of said plate member unbroken.
Claim 2
Dependent Claim
222 words
A one-piece plug for a panel aperture comprising a plate member having a flat, planar inside face portion, a peripheral edge and a plurality of resilient legs which depend from said plate member from the inside face portion side thereof adjacent said peripheral edge, said plate member having a plurality of spaced recesses embossed on the inside face thereof and adjacent each leg and said peripheral edge, said legs being formed by extensions of the plate member, each leg having: a first portion integrally joined to said peripheral edge which is folded back onto the inside face portion of said plate member and is positioned within said recesses and abutting the bottom of said recesses so as to lie substantially flush with and substantially in coplanar relationship with the said inside face portion of said plate member, each of said recesses having a width substantially equal to said first portions of said legs, a second portion which extends substantially at right angles to said plate member, and a third portion extending from said second portion, said third portion including a retaining part and an inwardly inclined lead-in part, said second and third portions of each of said legs projecting from the plate member at a position radially inwardly of said peripheral edge thereby leaving said peripheral edge of said plate member unbroken.
Claim 3
Dependent Claim
38 words
A plug as claimed in claim 1 including a sealing member of deformable material located on the plate member outside the legs so as to overlie at least a part of the folded back portions of the legs.
