TECHNICAL FIELD
The field of invention refers to ultralight and ultra-compact stroller and car seats suitable for children from 6 months to 4 years about up to 3000g weight approx. More in particular the invention concerns a stroller "all in one" which comprises, an unique principal body made in hard plastic materials as the PVC or other rigid material already approved for this type of use with high breaking load, low density, resilient, abrasion resistant and non-inflammable as well as for example the polypropylene or polymers in general or composite polymers, the whole structure on which will accommodate the child (including one sitting, one backrest with headrest and one footrest) in inflatable material, like inflatable PVC or other material already known and already approved for these types of use as the material that is used for the modern inflatable furniture or the drop stitch fabric (PVC with filament polyester) or polyurethane used in modern inflatable aircraft seats and already fully tested and respondent for more severe safety criteria used both in internal and external that through one or more electric pumps integrated in the principal platform allow the fast inflation and deflation of the sitting, backrest and footrest of the stroller and through the elongation of landing in tubular aluminum alloy or other light alloy, integrated and fully contained inside the main platform rigid, and through the extension of the wheels, allows the full opening of the stroller. BACKGROUND ART
With this stroller ultralight and ultra-compact inflatable stroller you want to remove the maximum the space that usually is due to a standard stroller even if closed with minimum size as those currently using closures "ad umbrella" - pat. No. Us20140091560 a l.
This stroller in fact is formed by a platform rigid PVC (or other material type that used for the base of baby car seats ) big as a sitting (0,50x0,45 m approximately) and about 0,15 m high, allowing, helped by one or more electric pumps incorporated along the back side of the platform, the rapid inflation (and deflation) of the seat of the backrest (fold) and of the footrest and the possible inflation of accessories as the container for the legs in winter or the roof, so make the all, once bellied, totally due to a real stroller for children.
The total weight of the stroller that willing to be an ultralight stroller will then not exceed 6000g.
The principal platform when closed is reduced in a rigid base that can be easily stacked in car (one on the other ) or home and may be carried as a simple backpack.
In addition a difference between conventional car seats or a difference between that is "inflatable" - pat. No. Us20130285420 a l (latter abandoned in date 05.01.2015 because no reply has been received from united states patent office by applicant) - this stroller is modular and allows the transformation of a single platform as both a baby stroller a baby car seat and as a baby high chair (replacing wheels of feet included in the same platform) and thus allows the use that is suitable for different needs.
This invention is totally new even with respect to the models that declare their modularity and are used as both a stroller a car seat and as an high chair as the mentioned patents referred to the research report, pat. No. De 202010003883ul and pat. No. Us 2015/130149al that instead in order to move from one to another method should necessarily be equipped with other outside structures so that not solve the problem the convenience of transport but instead complicate compelling to bring with itself other necessary structures to transform an element in another.
Other purposes and advantages of this invention will be evident proceed with the description that is purely descriptive and not limited.
For shortness, some features notes, methods, systems, procedures, components, circuits and so on, are not described in detail.
DISCLOSURE OF INVENTION
This invention involves a modular inflatable ultra-compact stroller and allowing , once closed , the minimum size possible in a single rigid platform that may become, depending on the situation, a baby stroller a baby car seat and a baby high chair.
The hard platform contains on the top of frame implanted to the four sides of the base by thermos welding bound or through appropriate glue or through other techniques authorized for such use as welding in radio frequency, the set of inflatable cells that includes in one unique inflatable body the seat, the backrest and footrest, in PVC or other material resistant to UV rays, non-flammable, puncture proof with surface protection in vinyl or for example through appropriate layers of insulation and protective material like the NOMEX/KEVLAR associated with breathable fabrics that allows to achieve the maximum comfort for a child find in contact with these areas, that is inflatable through one or more electric pumps associated with appropriate seal air valve incorporated in the rear and powered by rechargeable batteries at 12V from car cigarette lighter and from home through appropriate transformer.
You can think of achieving the inflation and deflation of main blower cells or through an external switch or through a breaker that turns over when the two superior arms are extended and deflated structure when these are stored.
The bottom of platform is pit and contains the entire bearing structure formed by telescopic tube extensible ( in aluminum alloy or other light alloy ) and wheels that properly extended allows to the stroller to be fully open.
At the foot of the facility once extended may be incorporated :
- wheels when using as a stroller;
- rubber feet in case of use as chair.
Leaving the structure closed inside the base, the platform is sticking with ISOFIX hooks directly by car then inflate PVC and transform the platform in baby car seat. Together with the ISOFIX hooks the structure may be engaged in top just by turning the upper handle so that it embraces the passenger seat head restraint.
The possibility of quick deflation of the stroller and the immediate closing for the structure allows such element to be easily stackable ( over one another ) limiting the maximum the overall total. Also two adjacent platforms associated through hinges or clamped on one adjacent side may allow the use of the stroller for twins or more brothers.
The inflatable and chair stroller can be integrated in its inflatable structure with other appropriate combination.
The manual switch of the electric pump place outside in correspondence of the panel allows the inflation of the primary group of cells which includes the seat , the backrest and footrest and the inflation of at least others two groups of inflatable cells (accessories), one for the roof in case of rain and an inflatable container for within which the child can put his legs in winter.
