Abstract
Abstract A grommet assembly for a wall panel and method of installation. The grommet assembly includes a grommet structure for insertion into the aperture made through a wall panel and includes pivotal locking arms for locking at the back face of the wall panel. An insert sleeve provides a circular wall that upon insertion into the grommet pivots the pivotal lock arms of the grommet. The insert sleeve is further provided with snap-engagement members that snap-engage to the circular wall of the grommet so that the grommet assembly is fastened together and to the wall panel. A retention ring may be used prior to cutting an aperture in the wall to secure fabric, or other wall coverings, around the aperture to be cut to prevent displacement or tearing, and to protect the outer wall surface. The method includes the field installation of the grommet assembly from one side of a wall panel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
180 words
A method for field installing a grommet assembly to and through an aperture formed in a multi-layer wall panel, said method comprising the steps of: attaching a retention ring to a covered face of a multi-layered wall panel; guiding a tubular cutting means having a circular cutting edge of a diameter substantially equal to the inside diameter of said retention ring against the wall panel within the retention ring; spinning and pressing said tubular cutting means to cut through the multi-layered wall panel; removing an excised portion of said multi-layered wall panel cut by said cutting means and forming thereby a circular aperture therethrough; non-resiliently inserting a grommet means through said aperture and disposing pivotal locking means adjacent a back surface of said multi-layered wall panel; inserting insert sleeve means through said grommet means; pivoting said locking means to lock at the back surface of said wall panel; snap engaging said sleeve means to said grommet means; and, arranging face plate means at the covered face of said multi-layered wall panel thereby masking over said retention ring and grommet means.
Claim 2
Independent Claim
180 words
A method for field installing a grommet assembly to and through an aperture formed in a multi-layer wall panel, said method comprising the steps of: attaching a retention ring to a covered face of a multi-layered wall panel; guiding a tubular cutting means having a circular cutting edge of a diameter substantially equal to the inside diameter of said retention ring against the wall panel within the retention ring; spinning and pressing said tubular cutting means to cut through the multi-layered wall panel; removing an excised portion of said multi-layered wall panel cut by said cutting means and forming thereby a circular aperture therethrough; non-resiliently inserting a grommet means through said aperture and disposing pivotal locking means adjacent a back surface of said multi-layered wall panel; inserting insert sleeve means through said grommet means; pivoting said locking means to lock at the back surface of said wall panel; snap engaging said sleeve means to said grommet means; and, arranging face plate means at the covered face of said multi-layered wall panel thereby masking over said retention ring and grommet means.
Claim 3
Dependent Claim
20 words
The method according to claim 1 wherein the step of attaching a retention ring comprises adhesively bonding a retention ring.
Claim 4
Dependent Claim
30 words
The method according to claim 1 wherein the step of attaching a retention ring comprises attaching a retention ring to a woven fabric covered face of a multi-layered wall panel.
Claim 5
Dependent Claim
46 words
The method according to claim 1 wherein the step of spinning and pressing the tubular cutting means comprises spinning and pressing the tubular cutter means to cut through a first laminate comprised of a fibrous material and through a second laminate comprising a honeycombed cardboard layer.
Claim 6
Independent Claim
160 words
A method for field installing a grommet assembly to and through an aperture formed in a wall panel, said method comprising the steps of: guiding a tubular cutting means against an outer face of a wall panel; spinning and pressing the tubular cutting means to cut through the wall panel; removing and excised portion of said wall panel cut by said cutting means and forming thereby a circular aperture therethrough; non-resiliently inserting a grommet means through said aperture and disposing pivotal locking means adjacent a back surface of said wall panel; inserting insert sleeve means having a terminal leading edge through said grommet means; pressing said terminal leading edge of said insert sleeve means against said locking means; pivoting said locking means to lock at the back surface of said wall panel; snap engaging said sleeve means to said grommet means; and, arranging face plate means at the front face of said wall panel thereby masking over said grommet means.
Claim 7
Independent Claim
160 words
A method for field installing a grommet assembly to and through an aperture formed in a wall panel, said method comprising the steps of: guiding a tubular cutting means against an outer face of a wall panel; spinning and pressing the tubular cutting means to cut through the wall panel; removing and excised portion of said wall panel cut by said cutting means and forming thereby a circular aperture therethrough; non-resiliently inserting a grommet means through said aperture and disposing pivotal locking means adjacent a back surface of said wall panel; inserting insert sleeve means having a terminal leading edge through said grommet means; pressing said terminal leading edge of said insert sleeve means against said locking means; pivoting said locking means to lock at the back surface of said wall panel; snap engaging said sleeve means to said grommet means; and, arranging face plate means at the front face of said wall panel thereby masking over said grommet means.
Claim 8
Dependent Claim
46 words
The method according to claim 5 including first attaching a retention ring to the outer face of said wall panel and the step of guiding the tubular cutting means comprising further the step of guiding a cutting means within the retention ring against the wall panel.
