DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
If the world of leisure and holidays seems to expand widely--to convince oneself, all is needed is considering the stream of holidaymakers who go to the seaside or to the mountain each year--it is nonetheless true that said holidaymakers pay more and more attention to their unnecessary expenses. For example, renting one or more beach mattress may account for an important part of the family's budget.
Of course, an inflatable mattress can be bought, but its implementation requires a true physical exercise, both for inflating-deflating and for carrying and storing it.
The invention set forth in this document is intended to overcome all these drawbacks.
SUMMARY OF THE INVENTION
Said invention is made up of an inflatable mattress and an associated device for automatic inflating and deflating of the mattress. This device is made interdependent with the mattress by means of gluing or any other means. No more need to get an air pump or being exhausted due to manual inflation: a photovoltaic cell array (1) supplies the power needed to operate a motor (2) driving a turbine (4) that enables the inflating of the mattress (5).
Conversely, the same motor is used to deflate said mattress when its power supply polarity is reversed by means of a three-position switch (3).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Furthermore, the mattress is made up of foldable panels enabling for example, from an effective size of 180 centimetres by 50 centimetres to get after folding an object whose size is only 50 centimetres by 47 centimetres, thus making its carrying easy, thanks to handles.
According to a more sophisticated embodiment of the invention, the part intended to be at the contact of the ground is made up of semi-rigid panels (27), coated with plastic or other, what will provide:
Referring to FIG. 1, the various panels that make up the mattress can be linked together by means of elastic straps (6) having differentiated restoring forces enabling automatic folding of panels according to a planned order.
For example, the elastic straps (6 bis) that link the lower panel with the intermediary lower panel will be designed so that they have the greatest force, thus enabling the folding of the lower panel against the intermediary lower panel first when inflating, and last when deflating, and so on.
Furthermore, the mattress can be provided with pockets meant for receiving a beach towel or various small objects.
As shown in FIG. 11, the mattress object of the present invention has fastening items enabling to use it while in lying, sitting or interm
