Personal mobility vehicle cover
A protective cover for a personal mobility vehicle (PMV) for use when the PMV is stored on ground or on a platform left attached to a vehicle. Only two mating flexible flat side panels form the cover. The arcuate mating upper margins are connected together by weather stitching, the lower margins being unconnected for cover installation over the PMV and preferably include a casing and a drawstring for tightening the lower margins beneath the PMV. The weather stitching is formed by multiple closely spaced lines of stitching through an inward seam allowance. The arcuate upper margins may be semi-circular, ellipse-like in shape, or similar to a side elevation profile of the PMV. The panels are preferably formed having a weather resistant outer layer and a felt-like substantially non-abrasive inner layer. The cover has a cover length and a cover height preferably established by formulas related to PMV profile sizes.

BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates generally to protective covers and more particularly to a flexible weather-resistant protective cover for personal mobility vehicles, (hereinafter referred to as a “PMV”).
2. Description of Related Art
PMVs are well known and are readily available for virtually all physically impaired individuals who find ambulation difficult at best, and impossible in worst-case scenarios. These physically impaired typically rely upon battery powered four-wheeled PMVs and three-wheeled PMVs sometimes referred to as “scooter trikes” or “power scooters”.
The user of a PMV may become so reliant upon it that there becomes a need to carry the PMV when traveling and when stored outside. Lift platforms attached to the rear of a vehicle, typically to a trailer hitch, are utilized for this transportation function wherein the PMV is placed atop a platform held above the ground at the back of the vehicle and, when needed, the lift platform either lowers or tilts to allow for motorized deployment or loading of the PMV thereatop after use.
During travel, inclement weather will take its toll on the PMV, as will the UV component of sunlight. Therefore, an investment in such a PMV of several thousands of dollars deserves adequate protection from the elements. Covers in the form of rigid or semi-rigid plastic or metallic material have been utilized in the past. These rigid covers tend to be oversized to accommodate a wide range of sizes of PMVs for universality. Flexible covers, also known in prior art, are typically formed of several rectangular panels, including a central band or panel and side panels to facilitate lateral expansion of the sides of the cover as these PMVs are typically in the range of 20″ to 30″ in width.
The present invention provides a generally universal configuration of a flexible weather resistant cover which is formed of only two side panels with a weather resistant seam running across the arcuately configured top surface of the invention. By properly selecting the height and length of each of the substantially identical side panels, virtually all sizes of PMVs may be accommodated for protective encasement thereof.
BRIEF SUMMARY OF THE INVENTIONThis invention is directed to a protective cover for a personal mobility vehicle (PMV) for use when the PMV is stored on the ground or on a lift platform attached to a vehicle. Only two mating flexible flat side panels form the cover. The arcuate mating upper margins are connected together by weather stitching, the lower margins being unconnected for cover installation over the PMV and preferably include a casing and a drawstring for tightening the lower margins beneath the PMV. The weather stitching is formed by multiple closely spaced lines of stitching through an inward seam allowance. The arcuate upper margins may be semi-circular, ellipse-like in shape, or similar to a side elevation profile of the PMV. The panels are preferably formed having a weather resistant outer layer and a felt-like substantially non-abrasive inner layer. The cover has a cover length and a cover height preferably established by formulas related to PMV profile sizes.
It is therefore an object of this invention to provide a flexible weather resistant protective cover for a PMV when stored either atop a rear lift platform attached to a vehicle or stored on a flat surface.
It is another object of this invention to provide an economically manufactured cover for a PMV which will accommodate virtually all sizes of PMVs.
Yet another object of this invention is to provide a multi-layer cover for a PMV preferably formed of two substantially identical side panels and stitched together with a weather resistant leak resistant top seam which adds both strength and water resistance to the cover and its protective features.
Still another object of this invention is to provide a PMV cover formed of double-layer sheet material having a weather-resistant outer layer and a scratch-free inner layer.
In accordance with these and other objects which will become apparent hereinafter, the instant invention will now be described with reference to the accompanying drawings.
Referring now to the drawings, and firstly to
The preferred material utilized for each of the flexible panels 12 and 14 is multi-layered as best seen in

As best seen in
The unobvious expandability nature of the invention 10 which is formed of only two substantially identical panels 12 and 14 as previously described, is shown in
Referring particularly to
Initially, the flexible panels 12 and 14 are laid back to back atop a flat surface with the outer vinyl surfaces 30 facing one another, and then the first seam 22 is stitched into place in inside-out pillowcase fashion. This initial stitching along 22 forms a seam allowance formed of arcuate edge portions 12a and 14a which typically measure about 1″ in width. Thereafter, a second stitching seam at 24 is installed along the entire arcuate seam 16 for added strength. Then, the now sewn together panels are reversed from the inside out orientation, one of the panels (12 or 14) is folded over against itself along fold line 14b and two additional closely spaced stitching lines are sewn at 26 and 28 through the three layers, the seam allowances 12a, 14a and 14 so that, when the cover 10 is expanded in the in-use configuration as shown typically in

As seen in
Referring now to
However, it is typically desired that the looseness factor LF be somewhat larger for easier deployment and removal and, therefore, in this instance, a looseness factor of an additional 10% added to the overall length to establish the preferred cover length CL is utilized. This renders the net looseness factor LF to be about 20% so that the cover length CL will be approximately 120% of the actual length AL1.

While the instant invention has been shown and described herein in what are conceived to be the most practical and preferred embodiments, it is recognized that departures may be made therefrom within the scope of the invention, which is therefore not to be limited to the details disclosed herein, but is to be afforded the full scope of the claims so as to embrace any and all equivalent apparatus and articles.
