Panel edge gasket

Claim 2

A gasket for sealing and retaining a panel edge comprising: a rigid, resiliently deformable elongated member having a base supporting upstanding, opposed first and second legs defining a panel edge receiving channel; first and second flexible fingers for sealing against opposing panel sidewalls adjacent the panel edge and for resisting removal of the channel from the panel, said first and second flexible fingers being respectively attached longitudinally along opposing inner faces of said first and second legs, said fingers further being adapted to flex downwardly into said channel and outwardly against said inner faces of said legs as the panel edge is moved into said channel; and relief means, undercut in said leg inner faces rearwardly of the point of attachment of said fingers, for receiving said downwardly and outwardly flexing fingers as the panel edge is moved into said channel.

Claim 3

The gasket of claim 1 wherein said first leg is longer than said second leg.

Claim 4

The gasket of claim 2 wherein said second leg has a bevel along its inner distal edge.

Claim 5

The gasket as in claims 1, 2 or 3 wherein said first finger is attached to said first leg inner face adjacent the distal edge of said first leg and said second finger is attached to said second leg inner face spaced from the distal edge of said second leg.

Claim 6

The gasket of claim 1 in which said elongated member is made from a polyvinyl chloride of approximately 78 Shore D Durometer and said fingers are made of flexible polyvinyl chloride of approximately 68 Shore A Durometer.

Claim 7

The gasket of claim 1 wherein said fingers are tapered in thickness.

Claim 8

A panel edge sealing gasket structure comprising: a rigid, resiliently deformable elongated member having a base supporting upstanding, opposed first and second legs defining a panel edge receiving channel; first and second flexible fingers for sealing against opposing panel sidewalls adjacent the panel edge and for resisting removal of the channel from the panel, said first and second flexible fingers being respectively attached longitudinally along opposing inner faces of said first and second legs, said fingers further being adapted to flex downwardly into said channel and outwardly against said inner faces of said legs as the panel edge is moved into said channel; relief means, undercut in said leg inner faces rearwardly of the point of attachment of said fingers, for receiving said downwardly and outwardly flexing fingers as the panel edge is moved into said channel; and sealing means attached to said base and directed opposite said channel, for forming a dynamic closure seal with an adjacent member.

Claim 9

A panel edge sealing gasket structure comprising: a rigid, resiliently deformable elongated member having a base supporting upstanding, opposed first and second legs defining a panel edge receiving channel; first and second flexible fingers for sealing against opposing panel sidewalls adjacent the panel edge and for resisting removal of the channel from the panel, said first and second flexible fingers being respectively attached longitudinally along opposing inner faces of said first and second legs, said fingers further being adapted to flex downwardly into said channel and outwardly against said inner faces of said legs as the panel edge is moved into said channel; relief means, undercut in said leg inner faces rearwardly of the point of attachment of said fingers, for receiving said downwardly and outwardly flexing fingers as the panel edge is moved into said channel; and sealing means attached to said base and directed opposite said channel, for forming a dynamic closure seal with an adjacent member.

Claim 10

The gasket of claim 7 wherein said first leg is longer than said second leg and said second leg has a bevel along its inner distal edge.

Claim 11

The gasket as in claims 7 or 8 wherein said first finger is attached to said first leg inner face adjacent the distal edge of said first leg and said second finger is attached to said second leg inner face spaced from the distal edge of said second leg.

Claim 12

A hermetically sealable container door or the like adapted for effecting a dynamic closure seal with an adjacent member, comprising: a door panel with peripheral edge portion about its perimeter; a panel edge gasket affixed to said peripheral edge portion, said panel edge gasket including a rigid, resiliently deformable elongated member having a base supporting upstanding, opposed first and second legs defining a panel edge receiving channel, first and second flexible fingers for sealing against opposing panel sidewalls adjacent the panel edge and for resisting removal of the channel from said panel edge, said first and second flexible fingers being respectively attached longitudinally along opposing inner faces of said first and second legs, said fingers further being adapted to flex downwardly into said channel and outwardly against said inner faces of said legs as the panel edge is moved into said channel, and relief means, undercut in said leg inner faces rearwardly of the point of attachment of said fingers, for receiving said downwardly and outwardly flexing fingers as the panel edge is moved into said channel; and sealing means, attached to said base of said panel edge gasket and directed oppositely to said channel, for effecting a dynamic closure seal with the adjacent member.

Claim 13

A hermetically sealable container door or the like adapted for effecting a dynamic closure seal with an adjacent member, comprising: a door panel with peripheral edge portion about its perimeter; a panel edge gasket affixed to said peripheral edge portion, said panel edge gasket including a rigid, resiliently deformable elongated member having a base supporting upstanding, opposed first and second legs defining a panel edge receiving channel, first and second flexible fingers for sealing against opposing panel sidewalls adjacent the panel edge and for resisting removal of the channel from said panel edge, said first and second flexible fingers being respectively attached longitudinally along opposing inner faces of said first and second legs, said fingers further being adapted to flex downwardly into said channel and outwardly against said inner faces of said legs as the panel edge is moved into said channel, and relief means, undercut in said leg inner faces rearwardly of the point of attachment of said fingers, for receiving said downwardly and outwardly flexing fingers as the panel edge is moved into said channel; and sealing means, attached to said base of said panel edge gasket and directed oppositely to said channel, for effecting a dynamic closure seal with the adjacent member.

Claim 14

The hermetically sealable container door of claim 1 including an adhesive mastic in said channel permanently affixing the channel to said peripheral edge portion.
