DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved add a vent window system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the add a vent window system 10 is comprised of a plurality of components. Such components in their broadest context include a small window and a support assembly. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
First provided is a vehicle 14. The vehicle has a window opening 16. The window opening includes an upper slot 18. The window opening also includes a lower slot 20. The window opening further includes a forward slot 22.
A large window 26 is provided. The large window has a top 28. The large window is formed of a transparent material. The large window is movable to a raised orientation and a lowered orientation. In the raised orientation, the top of the large window is within the upper slot of the window opening. In the lowered orientation the top of the large window is adjacent to the lower slot of the window opening.
A small window 32 is provided. The small window has an upper edge 34. The small window has a lower edge 36. The small window also has a forward edge 38. The small window further has a rearward edge 40. The small window is formed of a transparent material. The small window is positionable in the window opening. The upper edge of the small window is closely spaced from the upper slot. The lower edge of the small window is closely spaced from the lower slot. The front edge of the small window is closely spaced from the front slot.
A support assembly 44 is provided. The support assembly includes a peripheral frame 46. The peripheral frame encompasses the upper and lower and forward and rearward edges of the small window. The support assembly includes a tubular upper cylinder 48. The upper cylinder is provided upwardly from the peripheral frame adjacent to the upper edge of the small window. The support assembly includes a lower cylinder 50. The lower cylinder extends downwardly from the peripheral frame adjacent to the lower edge of the small window. The upper and lower cylinders are vertical and co-axial.
A lower attachment member 54 is provided next. The lower attachment member has a lowermost extension 56. The lower attachment member is formed of the lower cylinder and the lowermost extension. The lowermost extension has a forked lower end 58. The forked lower end is positioned over the top of the large window. The forked lower end spans the top of the large window. In this manner the lower attachment member is coupled to the lower slot. The large window is in the lowered orientation during operation and use.
Further provided is an upper attachment member 60. The upper attachment member is formed of a plurality of tubular telescoping sections. The upper attachment member has a lower section 62. The upper attachment member also has an intermediate section 64. The upper attachment member further has an upper section 66. The upper section is positioned within the upper slot during operation and use. A coil spring 68 is provided. The coil spring is positioned within the intermediate section and the lower section and the tubular upper cylinder. In this manner the upper attachment member may be contracted and extended for coupling the upper attachment member to the upper slot. The large window is in the lowered orientation during operation and use.
Provided last is an adjustment assembly 72. The adjustment assembly is formed in the lower attachment member. The adjustment assembly has a cylindrical stub 74. The cylindrical stub depends from the lower cylinder. The adjustment assembly has a cylindrical recess 76. The cylindrical recess is provided in the lowermost extension. The cylindrical recess rotatably receives the cylindrical stub. The adjustment assembly has downwardly facing hemispherical projections 78. The downward facing hemispherical projections are in a circular array around the stub. The adjustment assembly also has upwardly facing hemispherical projections 80. The upward facing hemispherical projections are provided in a circular array around the cylindrical recess. The upwardly facing hemispherical projections and the downwardly facing hemispherical projections are provided in axially contact. In this manner rotational movement between the upward facing hemispherical projections and the downward facing hemispherical projections is abated. The upwardly facing hemispherical projections and the downwardly facing hemispherical projections are axially spaced. In this manner rotational movement between the upwardly facing hemispherical projections and the downwardly facing hemispherical projections is allowed. Also in this manner the small window may be rotated about a vertical axis. Further in this manner the angular orientation of the small window may be varied and the extent of ventilation may be varied as a function of the angular orientation of the small window.
A wide variety of alternate embodiments are contemplated by the present invention. The primary preferred embodiment is illustrated and described herein. By way of example, the two separate upper and lower cylindrical sections about which the small window rotates could readily be replaced by a single tubular member with ends extending above and below the small window. Further, the small window is illustrated as being planar. Such planar window could include a tubular 90 degree elbow-shaped wind diverter. The diverter would have an input end outside of the car and an output end inside the car. Such diverter would be as a substitute for, or in addition to, the flat window as illustrated and described herein.
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.
