Problems solved by technology

Since the inflatable cover can't be too thick, it's not too heavy and doesn't take up a lot of space in the folded state, but the pressure can't be arbitrarily large
Therefore, there is a problem in the currently known inflatable umbrellas, they do not have the necessary stability in the inflated state against great external forces, for example due to strong winds or torrential rain

Embodiment Construction

[0037] figure 1 A perspective view (viewed obliquely from below) of the umbrella 100 according to the first embodiment is shown in the inflated state. The umbrella has an inflatable cover 105 . The cover is made of a flexible material, for example a suitable plastic material such as polypropylene, polyethylene terephthalate (PET) or similar plastics. Optionally, suitable film materials, in particular balloon films, can also be used. For example consider Heptax or , Biaxially oriented polyester film (boPET) made of PET. It is characterized by high tensile strength, chemical, mechanical and thermal stability and transparency. It is a good electrical insulator and exhibits slight water absorption. These properties are advantageous for the umbrella 100 according to the first embodiment.

[0038] In the umbrella 100 according to the first embodiment, in the inflated state, the inflatable cover 105 forms a central holding part 110, four umbrella support parts 115, 120, 125 a...

Abstract

An inflatable umbrella (100) has an inflatable covering (105) made from a flexible material. In an inflated state, said covering forms at least the following elements: a central holding element (110), at least three umbrella strut elements (115, 120, 125, 130) extending away from the central holding element, and at least one umbrella surface element (135, 140, 145, 150) stretched out by the umbrella strut elements. In this case, the central holding element (110) and each umbrella strut element are supported against each other at the respective contact point thereof. In the inflated state, the umbrella (100) has greater stability and resistance to external forces in comparison to previously known inflatable umbrellas.

Description

technical field [0001] The invention relates to an inflatable umbrella. Background technique [0002] Conventional umbrellas, especially umbrellas, are generally relatively large and often have cumbersome devices to maneuver. They interfere especially when they are not needed, ie for example when the sun or the rain has not yet appeared or the rain has stopped. It is due to this fact that they cannot be easily carried and therefore they are also often forgotten or lost. This in turn causes them to often not be carried, for example when sunshine and rain are not accounted for. If for example rain is not anticipated, people are largely unprotected, or people try to help from the rain by lifting items such as handbags or clothing such as jackets or the like above their heads. However, this may cause damage to these items and clothing. Furthermore, such auxiliary measures can only provide partial protection. [0003] Since this basic problem has long been known, partially c...
