Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to automobile shades and more particularly pertains to a retractable sun deflector shade adapted to be secured to the interior of an automotive windshield. 
     2. Description of the Prior Art 
     The use of automotive sun shades is known in the prior art. More specifically, automotive sun shades which are retractable are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     By way of example, U.S. Pat. No. 5,064,238 discloses a windshield sunshade assembly. The assembly includes a shade member that can be retracted or extended in order to cover the windshield from the inside of the vehicle. 
     Another patent of interest is U.S. Pat. No. 5,024,479 which discloses an automotive sun screen assembly. The assembly includes a flexible sheet normally rolled up into a helical configuration on a roller located within a tubular housing. The flexible sheet can be unwound from the roller to extend along the windshield. 
     A U.S. Design Patent of interest is U.S. Pat. No. 309,885. The patent illustrates a design for a windshield sun shade. 
     U.S. Pat. No. 5,044,687 discloses a sun vision which rotates and slides and is capable of covering the top horizontal and slanted parts of a front windshield. 
     Also of interest is U.S. Pat. No. 5,000,506 which discloses a sun shade for automobiles which can be actuated by electric motors. 
     While these shades fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe an automotive sun shade assembly which includes a supply housing and a take-up housing. Additionally, the prior art shades do not illustrate a shade assembly wherein the shade is rolled up into a housing to the right or left of the driver. Furthermore, the prior art shade assemblies do not illustrate a shade assembly which includes a rectangular frame element. 
     In this respect, the automotive deflector shade according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of shading the interior portion of an automobile.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved retractable deflector shade embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     The present invention relates to a retractable sun deflector shade 10 adapted to be secured to the interior of an automotive windshield 12. The shade device includes a rectangular frame 14 which is telescopic in width. The rectangular frame is made up of an upper frame element 16, a lower frame element 18, a cylindrical supply housing 20 and a cylindrical take-up housing 22. 
     The upper frame element 20 includes a first upper C-shaped frame element 26 having a forward end, a rearward end, an upper closed portion and a lower open portion formed by a slot 28. The upper frame element further includes a second upper C-shaped frame element 30 having a forward end, a rearward end, an upper closed portion, and a lower open portion formed by a slot 32. The forward end of the second upper frame element is telescopically received within the rearward end of the first upper frame element. In order to selectively allow or prevent telescopic movement between the first and second upper frame elements an upper thumb screw 34 is positioned within the rearward end of the first upper frame element 26. 
     The lower frame element 18 includes a first lower C-shaped frame element having a forward end, a rearward end, an upper open portion, and a lower closed portion formed by a slot 40. The lower frame element is C-shaped in a manner analogous to the C-shaped frame element 26 of the upper frame element 20 as described above, the C-shaped relating to the cross-sectional configuration of such element as can be seen in FIG. 3. The lower frame element further includes a second lower C-shaped frame element 42 having a forward end, a rearward end, an upper open portion, and a lower closed portion formed by a slot 44. The forward end of the second lower frame element. In order to selectively allow or prevent telescopic movement between the first and second lower frame elements a lower thumb screw 34 is positioned within the rearward end of the first lower frame element. 
     The cylindrical supply housing 20 extends vertically and includes an upper cylindrical supply subhousing having an upper extent, a lower extent, and a longitudinal slit 48 extending from the upper extent to the lower extent. The supply housing is coupled to the first upper frame element such that the lower open portions of the first and second upper frame elements are in communication with the longitudinal slit of the upper cylindrical subhousing. Furthermore, the supply housing is coupled to the first lower frame element such that the upper open portions of the first and second lower frame elements are in communication with the longitudinal slit of the lower cylindrical subhousing. 
     Positioned within the supply housing 20 is a cylindrical roll 52. The roll has upper and lower mountings 54 which rotatively receive the roll within the housing. Spring 56 are included within the housing which is operatively coupled to the cylindrical roll. The springs serve to rotate the cylindrical roll 52 to a first angular position. Thus, if the cylindrical roll is rotated it will return to its original angular position through the force of the springs. 
     The cylindrical take-up housing 22 is coupled to the second upper frame element 30 such that the lower open portions of the first and second upper frame elements are in communication with the longitudinal slit of the upper cylindrical housing. Furthermore, the take-up housing 22 is coupled to the second lower frame element 42 such that the upper open portions of the first and second lower frame elements are in communication with the longitudinal slit of the lower cylindrical housing. Positioned within the take-up housing 22 is an upper and a lower take-up reel 60 and 62. The upper cable take-up reel 60 is positioned within the upper cylindrical take-up housing, and the lower cable take-up reel 62 is in similar fashion positioned within the lower cylindrical take-up housing. The upper and lower cable take-up reels are joined by an axle 64. The axle is positioned within, and coaxial with, the take-up housing. 
     A two-way switch 68 is coupled to the lower cylindrical take-up housing 22. The switch serves to rotate the axle 64 positioned within the take-up housing in one of two angular directions. The switch can be coupled by lines 72 to the automobile fuse box, or alternatively, directly to the automobile battery. 
     The deflector shade 76 itself is formed from a sheet 78 of material having an upper edge, a lower edge, a forward edge and a rearward edge. The sheet can be formed from cloth, or alternatively, of plastic. Furthermore, indications such as a personalized message or an advertisement may be included upon the surface of the sheet of material. The forward edge 80 of the sheet of material is secured to the cylindrical roll 52 of the supply housing 20. Additionally, a rigid stiffening member can be sewn into the rearward edge of the sheet of material in order to provide additional rigidity. 
     Sewn within a hem 84 of the upper edge of the sheet of material is an upper cable 86. The upper cable has a forward end and a rearward end. The upper cable is positioned within the first and second upper frame elements. The rearward end of the cable extends beyond the rearward edge of the sheet of material and is coupled to the upper cable take-up reel. 
     Sewn within a similar hem of the lower edge of the sheet of material is a similar lower cable. The lower cable has a forward end and a rearward end. The lower cable is positioned within the first and second lower frame elements. The rearward end of the cable extends beyond the rearward edge of the sheet of material and is coupled to the lower cable take-up reel. 
     In use, the frame is secured to the interior of an automotive windshield. The securement can be accomplished by way of suction cups 88 preferably, but adhesives, glues, screws, fasteners, or any other such means that would provide positive securement could be utilized. 
     The two-way switch 68 is then coupled to the fuse, or automobile battery. Activation of the switch in a first direction rotates the upper and lower take-up reels 60 and 62 which draw the sheet out of the supply housing. The sheet is then in a position to cover the windshield and keep out harmful sunlight and radiation. Activation of the switch in a second direction allows for the rolling up of the sheet by springs 56. When the switch is activated for the second direction, the upper and lower take-up reels provide for a controlled roll up against the force of the spring biased cylindrical roll. 
     FIGS. 7 and 8 illustrate an alternate embodiment of the invention according to the embodiment of these Figures, a modified sheet of fabric, whether cloth or plastic is employed. The modified sheet material 90 differs from that of the prior embodiment by having a panel 92 separated from the remainder of the sheet material along the majority of its extent, in an inverted U-shaped configuration according to the preferred embodiment as shown in FIG. 7. The lower edge of the panel remains integrally formed with the remainder of the sheet material. 
     In association with the inverted U-shaped line of separation is a separable fastener 94, preferable a zipper which may be used by the occupant of the car to open or close the sheet material to allow or preclude viewing when the automobile shade is in the deployed orientation. The zipper may be moved to one end or the other to open or close the panel as desired by the operator. Other releasable fasteners could readily be employed. A pile-type fastener, such as Velcro brand pile-type fastener, has been found to be an acceptable alternative. 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will 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.
