AI Technical Summary

Benefits of technology

The invention describes a method to make an inflatable umbrella using conventional films, which makes the process cheap and efficient. The method is also dependent on the number of struts, which helps in maintaining stability during inflation. When the umbrella is inflated, the struts are folded over the holding element, which supports them and keeps the umbrella stable.

Problems solved by technology

The production of the umbrella by means of blow-molding, however, is not very effective since this process takes a relatively long time.

Embodiment Construction

[0048]FIG. 1 shows a top view of an inflatable umbrella according to the invention 1. The umbrella 1 essentially has a Y-shaped outer contour 18. The top view shows a film 2 of the umbrella 1, namely a cover layer 3. The outer contour 18 corresponds to a second contour 5 along which during production, the umbrella 1 has been separated from the films 2 that were used to produce it. The outer contour 18 or second contour 5 is therefore essentially Y-shaped; two short legs 20 of the Y-shape are connected by the outer contour 18 or second contour 5 to free ends 19 of the legs 20 that suspend an umbrella surface 8. A first contour 4 along which two adjacent films 2 of the umbrella 1 are connected to each other likewise has a Y-shape, in fact without the connection of the free ends 19 of the legs 20. The first contour 4 has a width b of a few millimeters. The outer contour 18 and the second contour 5 extend on the outside of the first contour 4. Due to the Y-shape of the first contour 4, ...

Abstract

A method for producing an inflatable umbrella with a number of struts n, in which n films are positioned on top of one another in at least some regions; two films form cover layers and the other films are folded as intermediate layers and arranged between the cover layers; the films are connected along a first contour, with each pair of adjacent films being connected to each other; and the umbrella is separated from the films in at least some regions along a second contour. The invention also relates to an inflatable umbrella.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a method for producing an inflatable umbrella and also relates to an inflatable umbrella.BACKGROUND OF THE INVENTION[0002]Several inflatable umbrellas, particularly for use as rain umbrellas, are known from the prior art. An important advantage of inflatable umbrellas over conventional umbrellas lies in the fact that inflatable umbrellas take up very little space when they are not inflated and can thus be carried along easily. For example, an inflatable umbrella can easily be carried in a purse or a jacket pocket. Then if it begins to rain, e.g. during a walk, then the inflatable umbrella is simply inflated, in particular blown up, so that it can then provide the user with protection from the rain. If the rain stops again or if the user has arrived at a sheltered place, then the inflatable umbrella can be folded up again by letting the air out of the umbrella. The umbrella can then once more be accommodated in a pocket or ...
