A magnet support and retainer for post-construction installed interior storm windows formed as a unitary plastic extrusion having a U-shaped pane-receiving portion, a rigid magnet mounting portion and a connecting portion, preferably flexible, formed therebetween. The magnet mounting portion includes an elongate rigid planar strip having a pair of depending edge flanges defining a cavity for tightly receiving a strip magnet of generally rectangular cross-section and an intermediate depending flange including barb portions adapted to be received tightly within a facing groove formed in the magnet. The opposite magnet face is engaged upon a ferromagnetic strip or sash surface for installation of the storm window. Resilience is afforded sufficient to compensate for irregularities in the pane or in the cooperating ferromagnetic surface when the storm window is installed. The magnet is force fitted in the cavity enabling easy assembly.
In combination, a pane of light transmitting sheet material and a magnet support and retainer therefor for accommodating a magnet body and enabling magnetic support of said pane over a post construction window installation to provide a substantially sealed dead air space therebetween, said magnet support and retainer comprising, rigid pane-receiving means, rigid magnet-receiving means and connecting means therebetween, said pane-receiving means formed as a U-shaped member having a side entrance for receiving the pane tightly therethrough, said magnet-receiving means including cavity-defining means for tightly accommodating a magnet body and cooperable resilient means formed in said cavity and said magnet body comprising tongue and groove means provided on said retainer and said magnet body respectively capable of being coupled together for resiliently mounting the magnet body within said cavity whereby to compensate for variations in the pane and in the surface adherent to said magnet body said tongue means includes resilient outwardly extending ribs unitary therewith, the cross-section of said tongue means being formed in the configuration of a barbed arrowhead, at least some portions thereof being formed of lesser durometer material than the material forming said pane-receiving and magnet-receiving portions.
In a post-construction storm window installation wherein a substantially planar pane of rigid light transmissive sheet material is applied over a window sheet frame and carries magnet means for adherence to a facing ferromagnetic surface carried by the window frame and a unitary magnet support and retainer member is provided for mounting a magnet body of the pane to present a planar face to the ferromagnetic surface, said magnet support and retainer having a rigid pane-retaining portion and a rigid magnet-retaining portion and connecting portions therebetween, the pane-retaining portion formed as a U-shaped member having a narrowed side entrance for edgewise reception of the pane, and the magnet body having inner and outer faces;
A combined support and retainer for a magnet body and a generally rigid sheet material comprising first and second rigid support portions, and unitary connecting portions therebetween, said first portion including a side opening slot for securely accommodating edgewise a rigid sheet material, said second portion having outwardly opening cavity defining means for retaining a magnet body, a magnet body having inner and outer generally parallel faces, said second portion further having longitudinally extending depending tongue means, and longitudinal groove means formed in the inner face of said magnet body capable of receiving said tongue means therein when said magnet body is received with said cavity, the cavity being of size and configuration for retaining said magnet body force-fitted therein, said tongue means including outwardly extending barb means having tips of lesser durometer whereby to permit limited resilience between the magnet body and the retainer to afford compensation for variations in the surfaces to which the magnet body is adhered whereby to preserve the engagement of the magnet thereto.
