Problems solved by technology

Therefore no fundamental technological advances can be achieved compared to common foldable folding umbrellas
On the other hand, the gas generating device in the umbrella for inflating the umbrella is too complex in design and too expensive to manufacture, so that a correspondingly manufactured inflatable umbrella, especially for such umbrellas for one-time use, cannot be used efficiently. attractive price offer

Embodiment Construction

[0033] exist figure 1shows a perspective view from above of a first embodiment of a self-inflating umbrella according to the invention. The self-inflating umbrella 10 essentially consists of an inflatable shell 11 consisting of a flexible material such as a suitable plastic material such as polypropylene or similar. Alternatively, suitable film materials can also be used optionally. In the non-use state, ie before inflation or after the gaseous substance has been expelled, there is a vacuum in the inner cavity of the housing 11 so that the housing can be folded to occupy a very narrow space. Said housing 11 is made in such a way that it has a figure 1 In the form of the cap shown in , the cap can be kept over the head for protection from the rain. exist figure 2 In the perspective view seen from obliquely below, it can be seen that on the concave side of the cap, a handle 13 made of flexible material is arranged in the center, through which the hand can be stretched durin...

Abstract

The invention relates to a reusable, self-inflating umbrella, comprising an inflatable cover (11) made of a flexible material and an inflating mechanism (12). The interior of the cover (11) can be connected to the inflating mechanism (12) by a gaseous substance being created by a chemical reaction. The gaseous substance then inflates the interior of the cover (11). The chemical reaction may comprise a soda granulate being dissolved in citric acid. The citric acid may be accommodated in a container that is caused to rupture by the application of pressure to the outside of the inflating mechanism (12) by a user such that the chemical reaction is triggered as a result.

Description

technical field [0001] The present invention relates to a reusable self-inflating umbrella having an inflatable shell and an inflation mechanism. Background technique [0002] Conventional umbrellas for everyday use are generally relatively intrusive and often cumbersome devices to operate. Umbrellas are especially in the way when they are not needed, i.e. the rain that might be expected has not yet fallen, or has stopped. Precisely due to the fact that umbrellas are not conveniently portable, they are also often forgotten or forgotten. This in turn leads to the fact that umbrellas are often not carried when rain is not expected. When it rains unexpectedly but does fall, people are largely unprotected, or people try to protect themselves from the rain in an emergency by covering their heads with objects such as bags or clothing such as jackets and the like , but these items and clothing suffer from this. [0003] Since this major problem has long been known, partially re...
