Technical Field
This invention relates to hail protective covers for motor vehicles with focus on inflatable protective covers for automobiles, boats, camper trailers/caravans and motorcycles.
Background of the Invention
Protective covers were fabricated to help keep motor vehicles parked outside be protected from weathering and environmental materials such as dust, rain, frost and snow. With the vehicles protected from the elements, longer lifespan of the surfaces and internal components are assured. Since these are intermittent protection solutions, these are meant to be portable and as such, are typically folded or rolled up for ease of storage and portability.
Back in the day, covers were made of materials that were available for the purpose, like the one whose patent (U.S. Patent No. 1,728,437) was issued to Mott on 17 September 1929. This vehicle cover was made of canvas. Canvas by nature is tough but heavy and bulky. And these properties pose difficulty and inconvenience during fitting, removal and packing.
Consequently, canvas offers no protection against another vicious element - hail. In fact, none of the later materials can offer enough cushion to protect against the damaging effects of hail, without being heavy or bulky or both. Plasticfoams offer protection to a certain degree and would normally compromise either flexibility or volume or both. One such art was granted a patent, US4807922A; submitted by Glover, Ralph S. Another previous art of a similar nature was the one by Timerman, Jerry L. (US5401074A).
One seemingly feasible solution to problem of bulk and weight of the cushioning medium is having inflatable pockets that will provide the cushioning protection from precipitating hail. Several prior arts display merit and are worth mentioning. US20090108624A1 by Hunt, Glen Ralph would top the list. Wang, S.B. (US5350000A), Rudolph Shores (US5890525A), Rory Francis O'Neill (US5941594A), Robert Tellez (US7360820B2), Roland S. Rother (US11148514B2), Michael A. Siciliano (US8985672B2) complete the honourable mentions. In Australia, one notable prior art is by Lily Johnstone Dawson (Australian application number 2017280100).
All of these may give excellent protection to a vehicle except for a limiting factor: lack of versatility and/or adaptability to various size, shape and design of vehicles. It will not be economically viable to come up with several sizes each of which will only accommodate a handful of vehicle models. Being in one piece, these arts will have limitations in accommodating various models with slight differences in the dimensions.
Summary of the Invention
The object of this invention is to provide protection while having the flexibility to accommodate various dimensions because of its modularity. Having the inflatable in several bladder sections add to the versatility of the device and adaptability to various shape and size of subject vehicles. These separate airtight inflatable sections will be connected by rubber or plastic flexible tubes and held together by a car cover of flexible, preferably elastic, material.
The main surface to be covered with the inflatable airtight bladders will be the dorsal part of the vehicle. In cars, this will include the bonnet (hood), front windshield panel, roof, rear glass panel, and the boot(trunk). Protection may also be provided on the side panels, that will include the fender and doors (with the glass windows) and rear fender panels. The pockets or cells within the bladder will be the result of fusing the two sheets by heat welding. This will be done with a wave or net/mesh pattern not just for aesthetic purposes but for even distribution of cushioning protection in the different parts of the surface. THe pockets/cells will be connected by air channels which, basically, are just gaps in the dividing weld seams. The size of the cells will be dictated by the thickness of the bladder required. This is another interesting property of the design. For example, the part that covers the glass panels may not need to be as thick as the ones covering the metal panels. The same goes with the side inflatable panels that may not need to be as thick as the dorsal inflatable panels.
The inflatable bladders will be attached to a (car cover) overlay of flexible, preferably elastic, material by adhesive-backed velcro strips or plastic automatic snaps. The use of velcro or plastic snaps avoids corrosion that may be expected when using metal fixing materials.
Each bladder can have its own inflation valve or linked with a rubber/plastic tube to a main bladder with an inflating and deflating valve.
Deflated, this device can be folded and fit into a portable carry bag that can be stored in the trunk of the car or any appropriate storage compartment in the camper trailer/caravan, garage or boatshed.
To install, simply spread the device over the vehicle just like any vehicle cover. Secure on the wheels by joining the quick release buckles attached to the straps that are in turn fastened to the overlay. The same strap-buckle assembly may also be provided along the side that will run through the ventral part of the vehicle for a more secure anchor. To inflate, simply locate the inflating valve/s that will be protruding through the overlay. Attach the nozzle of the pump, secure the connection and start inflating; stopping only when the recommended pressure is attained. Hand, foot pumps or any electrical pump (12-volt vehicle battery pump or portable electric pump) will do the job.
Alternatively, when rapid inflation is required, compressed gas, such as carbon dioxide, nitrous and helium, can be used. In this set-up, a sealable valve will be affixed instead of the regular inflating valve. The compressed gas may be contained in pressurised cartridges and discharged only when required.
This rapid or instantaneous inflation option can be very handy in instances where immediate protection is required, e.g., being caught in a hailstorm in the middle of the road.
In a situation where the user needs to be under cover as well, an option to provide an overlay with openings that match the vehicle doors can be provided. These can be opened and closed with double- or reversible-tab zipper sliders sewn into the overlay sheet.

Detailed Description of Embodiments
In totality, the uniqueness of the invention resides in the synergistic function of the two components. The overlay sheet or cover holds the inflatable sectional bladders together as a whole unit that will protect the surfaces of the vehicle. It will hold all the bladders against the surfaces they protect.
The nature of the overlay will help in easing the whole device onto the vehicle as the device will be put in place like a normal vehicle cover. Elastic material is preferred to have a tight, snug fit against the contours of the vehicle. The overlay will have holes where the inflating and deflating valves can go through, making it easier to inflate/deflate the device. Straps will be affixed on locations on the draping part of the overlay where they can be anchored on all four wheels. Quick-release plastic buckles will secure the straps in place. Additional straps will be affixed on the middle part of the draping sides for added anchoring.
The novelty of this device lies in the modularity of sectioned inflatable bladders. This is achieved by conjoining two (2) sheets of flexible plastic material (PVC, TPU, woven polyester or nylon) by heat welding them at the edges to form an air-tight bladder (think of an inflatable pool toy or inflatable mattress). These sheets will be patterned after the shape of the surface they are meant to protect, with slight size adjustments to make up for surface area lost during inflation. For an even distribution of thickness in the bladder, cells or pockets will be formed by heat-welding the two sheets within the bladder in a wavy or net/mesh pattern. These cells/pockets will be connected by air/gas channels that are formed by leaving gaps between the wave welds (Figure 1). The thickness of the pockets can be determined by the distance between wave welds; the bigger the distance, the thicker the cells. This is an interesting property of these modular bladders. The thickness can be adjusted relative to the amount of protection required by respective surfaces.
Inflating/deflating valves will be affixed to the bladders to facilitate inflation/deflation. Bladders can also be connected by flexible plastic/rubber tubes, when valves are affixed to one main bladder that supplies supplemental smaller bladders. An example will be the smaller rear glass panel support bladder connected to the roof panel bladder.
The inflatable bladders will be fastened to the overlay using a pair of velcro with adhesive backing located on various points. Alternatively, where woven plastic sheet is used, plastic automatic snaps can also be used.
