Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The field of invention relates to storm window and door coverings, and more particular pertains to a new and improved storm window and door covering apparatus wherein the same utilizes a selectively securable flexible membrane to overlie a window or storm door opening securable to a companion strip adhered to the frame of the window or door opening. 
     2. Description of the Prior Art 
     Window and door coverings are utilized in the prior art to overlie existing window and storm doors to enhance a thermally insulative effect in an effort to minimize heat loss therethrough, particularly in wintry scenarios. The prior art has heretofore utilized various manners of securement of the coverings, but has heretofore failed to provide the details as set forth by the instant invention to provide a covering of enhanced thermally insulative securement of the edge to edge relationship of the transparent covering relative to the window or door framework. Examples of the prior art include U.S. Pat. No. 4,103,728 to Burdette, et al., wherein a circular elongate cylindrical bead is positioned within a channel defined by a generally square configuration to secure the bead therewithin. 
     U.S. Pat. No. 3,805,872 to Lorber sets forth a magnetic means for attaching a screen to overlie an associated door or window framework. 
     U.S. Pat. No. 3,763,917 to Antinone sets forth a screen securable to a framework utilizing separate fastening means to effect the association. As may be appreciated, the attachment of screens to frameworks by its inherent nature does not concern itself with the thermal insulative property of the screens and accordingly, the attaching of screens to a framework need not include thermally insulative edge binding as set forth by the instant invention. 
     U.S. Pat. No. 3,251,399 to Grossman sets forth a window covering to overlie a screen utilizing hook and loop fastening elements, wherein the covering includes a zippered flap to enable selective opening of the window without disassociation of the hook and loop fastener securement portions. 
     U.S. Pat. No. 4,249,589 to Loeb sets forth a screen of sheeting covering to overlie a window utilizing hook and loop materials to effect the association. 
     As such, it may be appreciated that there is a continuing need for a new and improved storm window and door covering apparatus which addresses both the problems of effectiveness in sealing of the covering relative to the framework of the window or door opening, as well as ease of use of the organization, and in this respect, the present invention substantially fulfills this need. 
     SUMMARY OF THE INVENTION

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 13 thereof, a new and improved storm window and door covering apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the storm window and door covering apparatus 10 provides an improvement of the prior art, as illustrated in FIG. 1, wherein a transparent flexible membrane 3 formed with a reinforcing securement edge 4 is adhered to an adhesive strip 2 about an associated window frame 1 to overlie a window &#34;W&#34;. Accordingly, the window &#34;W&#34; may be substituted by a door, as desired. 
     FIG. 2 is illustrative of the instant invention wherein the window &#34;W&#34; is provided with a transparent membrane 11 that is formed with a membrane first securement strip 12 for association with a second securement strip 13 of the associated window frame 1. As illustrated in FIG. 4, the first securement strip 12 is formed as a channel of an ellipsoidal cross-sectional configuration 14 to receive a securement projection 15 of a complementary ellipsoidal cross-sectional configuration receivable within the channel 14. An adhesive strip 16 is formed to a bottom surface of the second securement strip for adhesive association with the window frame 1, as illustrated in FIG. 7 for example. The bottom surface 12a of the first securement strip and the top surface 13a of the second securement strip 13 are of an equal length to minimize overlap, and wherein both surfaces are planar to effect a weather-tight seal minimizing thermal transfer therethrough. 
     FIG. 8 illustrates a modified first securement strip 12 formed with a plurality of securement channels 17 therewithin of a diamond cross-sectional configuration for receiving plural securement projections 18 integrally formed to the second securement strip 13 of an equal diamond shaped configuration receivable within the channels 17. The plural interlocking arrangement ensures an improved barrier against thermal flow therethrough, and further resists dislodging of the projections relative to the channels, as may occur when the flexible transparent membrane 11 is subjected to drafts, impact, and the like. 
     FIGS. 11-13 illustrate a modified first securement strip 112 for interlocking association with an improved second securement strip 113. The first securement strip is formed with a truncated cylindrical channel 19 positioned medially of a projecting ellipsoidal projection 20 formed at the perimeter of the membrane 11 as the first securement strip 112. The cylindrical channel 19 receives a truncated cylindrical projection 21 formed medially within an ellipsoidal groove 22 at the floor thereof, as illustrated in FIG. 12. The projection 21 is received within the groove 19, while similarly the projection 20 is received within the similarly configured ellipsoidal channel 22. Hook and loop fasteners 23 may be utilized in association with further hook and loop fasteners 24 formed to the window frame 1 to enable securement of the second securement strip 113 thereto. It should be noted that the inherent flexibility of the first and second securement strips enable the interlocking engagement of the projections in association with the channels of opposing strips. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
