Abstract
Abstract A two-piece molded plastic support assembly for mounting on a wall or door panel of a storage refrigerator or freezer compartment, comprises a grommet member which is insertable into a preformed hole from the front side of the panel and further comprises a support member which is detachably mounted on the grommet member to operatively engage a shelf or drawer or a door handle for the storage compartment. The grommet member has a grommet shank insertable into the hole on the panel's front side (prior to in-situ application of liquid insulating foam to the panel's rear side). The grommet shank comprises a resilient annular grommet flange engageable with the panel's front side to seal the panel hole against foam or air leakage and also comprises releasable exterior locking tabs for engaging the panel's rear side to lock the grommet member in place and to effect sealing action of the grommet flange. The grommet shank also has a blind bore extending axially thereinto from its front end. The support member comprises a support shank which has resiliently flexible tabs thereon which frictionally engage the grommet bore. The support member also comprises a rigid flange which overlies the grommet flange and transfers the load to the panel instead of the grommet.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
261 words
In combination: a panel having a hole therethrough and having a front side and an opposite rear side; and a support assembly for engaging an object to be associated with said front side of said panel and including a grommet member formed of relatively resilient plastic and a support member formed of relatively non-resilient plastic, said grommet member having a bore therein extending inwardly from said front side of said panel and closed at its other end, and said support member being mounted in said bore and engageable with said object; said grommet member being releasably mounted by insertion into said hole from said front side of said panel and having portions extending from said hole on the front and rear sides of said panel; the portion of said grommet member extending on said front side of said panel comprising a resiliently deformable flange disposed on said front side of said panel and engaged therewith to effect a sealed relationship of said grommet member with said edge of said hole; said grommet member further comprising resilient locking projections disposed on said rear side of said panel and releasably engaged therewith to effect releasable mounting of said grommet member in said hole and to effect resilient deformation of said deformable flange; said support member including a serrated rigid shank removably inserted into said blind bore in said grommet member and having a support portion extending from said front side of said panel for engagement with said object and including a rigid flange engageable with said front side to transfer a load thereto.
Claim 2
Dependent Claim
261 words
In combination: a panel having a hole therethrough and having a front side and an opposite rear side; and a support assembly for engaging an object to be associated with said front side of said panel and including a grommet member formed of relatively resilient plastic and a support member formed of relatively non-resilient plastic, said grommet member having a bore therein extending inwardly from said front side of said panel and closed at its other end, and said support member being mounted in said bore and engageable with said object; said grommet member being releasably mounted by insertion into said hole from said front side of said panel and having portions extending from said hole on the front and rear sides of said panel; the portion of said grommet member extending on said front side of said panel comprising a resiliently deformable flange disposed on said front side of said panel and engaged therewith to effect a sealed relationship of said grommet member with said edge of said hole; said grommet member further comprising resilient locking projections disposed on said rear side of said panel and releasably engaged therewith to effect releasable mounting of said grommet member in said hole and to effect resilient deformation of said deformable flange; said support member including a serrated rigid shank removably inserted into said blind bore in said grommet member and having a support portion extending from said front side of said panel for engagement with said object and including a rigid flange engageable with said front side to transfer a load thereto.
Claim 3
Dependent Claim
236 words
A support assembly for releasable mounting in a hole in a panel and for operatively engaging an object associated with said panel, said support assembly comprising: a relatively resilient plastic grommet member, said grommet member comprising a shank for insertion into said hole from one side of said panel, a flexible deformable grommet flange extending circumferentially outwardly at one end of said shank for engaging said one side of said panel and operating to seal said hole, a plurality of resilient locking projections axially spaced from said flange and projecting outwardly from said shank for engagement with the other side of said panel whereby cooperation of said locking projections and said flange with said panel releasably locks said grommet against axial displacement in said hole, and effects deformation of said flexible grommet flange and a blind bore extending inwardly from said one end of said shank; and a relatively non-resilient plastic support member releasably mountable on said grommet member, said support member comprising a support shank having non-resilient inflexible serrations extending transversely on the outer surface thereof and releasably insertable into said bore in said grommet member, said support member further comprising an outer support portion adapted to supportably engage said object, and an outwardly extending rigid flange means between said support shank and said support portion and engageable with said one side of said panel to transfer loads thereto instead of to said grommet member.
Claim 4
Dependent Claim
236 words
A support assembly for releasable mounting in a hole in a panel and for operatively engaging an object associated with said panel, said support assembly comprising: a relatively resilient plastic grommet member, said grommet member comprising a shank for insertion into said hole from one side of said panel, a flexible deformable grommet flange extending circumferentially outwardly at one end of said shank for engaging said one side of said panel and operating to seal said hole, a plurality of resilient locking projections axially spaced from said flange and projecting outwardly from said shank for engagement with the other side of said panel whereby cooperation of said locking projections and said flange with said panel releasably locks said grommet against axial displacement in said hole, and effects deformation of said flexible grommet flange and a blind bore extending inwardly from said one end of said shank; and a relatively non-resilient plastic support member releasably mountable on said grommet member, said support member comprising a support shank having non-resilient inflexible serrations extending transversely on the outer surface thereof and releasably insertable into said bore in said grommet member, said support member further comprising an outer support portion adapted to supportably engage said object, and an outwardly extending rigid flange means between said support shank and said support portion and engageable with said one side of said panel to transfer loads thereto instead of to said grommet member.
Claim 5
Dependent Claim
51 words
A support assembly according to claim 2 wherein an annular recess is provided in the surface of said grommet flange confronting said one side of said panel to enable resilient movement of said grommet flange against said one surface to effect a seal in response to engagement of said locking projections.
Claim 6
Dependent Claim
41 words
A support assembly according to claim 2 or 3 wherein a recess is provided in said flange means of said support member for accommodating said grommet flange and enabling engagement of said flange means with said one side of said panel.
Claim 7
Dependent Claim
39 words
A combination according to claim 1 further including solidified foamed-in-place plastic insulation adhering to said rear side of said panel and to that portion of said grommet member extending from said hole on said rear side of said panel.
