Definitions

  • the present invention relates to a reusable, self-inflating umbrella comprising an inflatable envelope and an inflation mechanism.
  • an umbrella in a number of documents, it has therefore been proposed to configure an umbrella as an inflatable umbrella that is inflated for use and can otherwise be transported in a practicable manner in a folded-together form.
  • a gas-filled envelope replaces the screening material commonly tensioned by metal struts, thus ensuring the necessary stiffness.
  • Document DE 20 2004 002 172 U1 describes an umbrella or sunshade which is provided with an inflatable umbrella- or disk-shaped air chamber coupled to a compressed air cartridge.
  • a valve which can be actuated by a push-button, it is possible to control the supply of air from the cartridge to the air chamber.
  • the umbrella or sunshade is no longer needed, the air is released from the air chamber by means of the valve and the umbrella or sunshade is folded together and stowed in a case.
  • a compact, self-inflating umbrella for once-only use is proposed.
  • the umbrella is provided with a case, the bottom portion of which serves as a handle when using the umbrella.
  • a pressure vessel filled with a pressurised boiling liquid is disposed inside the case, near the bottom thereof.
  • the inflatable shielding screen is stowed away in a folded state inside the case.
  • a closure element of the pressure vessel is broken away by external mechanical action so that the liquid escapes through the opening thus produced, expands thereby and is guided as a gaseous substance into the inflatable chambers of the screening shield.
  • the screening shield is pressed out of the upper part of the case and unfolds to its full size.
  • the umbrella is thrown away after one use.
  • the proposed umbrellas include bulky elements such as handle members, cases or gas production devices, with the result that, in the unopened state, they are still too bulky and require too much space.
  • a decisive technical advance compared to standard telescoping pocket umbrellas cannot be achieved with such approaches.
  • the gas production devices provided in them for inflating the screening shield are too complex in design and too expensive to produce, with the consequence that inflatable umbrellas produced in this manner, especially those for once-only use, can not be offered at an attractive price.
  • the object of the present invention is therefore to specify a self-inflating umbrella which is space-saving when not in use and which can also be produced with less production effort. More particularly, the object of the present invention is to define a reusable, self-inflating umbrella which essentially no longer contains any bulky elements.
  • a self-inflating umbrella according to the present invention comprises an inflatable envelope made of flexible material and an inflation mechanism, wherein a gaseous substance with which the inflatable envelope can be inflated can be produced inside the inflation mechanism by means of a chemical reaction.
  • the present invention thus proceeds from the basic realisation that the devices proposed in the published prior art for providing or producing a gas for inflating the shielding envelope are invariably too voluminous in design and therefore too bulky, since the medium to be used for inflation must be enclosed in a pressure-tight container when not in use, be it in the form of a compressed air cartridge or a pressurised boiling liquid enclosed in a container.
  • One essential idea of the present invention is therefore to provide the gaseous substance for inflating the umbrella in some other manner that obviates the need to use bulky containers. This is made possible by the present invention.
  • the inventive idea provides the basis for storing certain starting substances, with the aid of which the gaseous substance is to be produced, without using rigid pressure vessels as storage. More particularly, two or more chemical substances are disposed, as starting substances for the chemical reaction, spatially separate from each other inside the inflation mechanism, and the chemical reaction can be triggered, when the object is used, by the chemical starting substances coming into contact with each other. This basically obviates the need for the chemical starting substances to be accommodated in rigid, pressure-tight containers. It is not even necessary, in essence, for them to be accommodated in containers at all when in their initial state.
  • one exemplary and advantageous embodiment provides that at least one of the two chemical substances is accommodated in a container which can be opened externally by the effect of pressure, such that the chemical substance contained therein is released and can come into contact with the respective other chemical substance.
  • the container is disposed at a defined position inside the inflation mechanism, and that a marking is applied at a location on the outer wall of the inflation mechanism which is closest to said position. The marking serves to indicate to the user that the marked place be pressed in case of use, thus opening the container by the effect of pressure.
  • the container may be provided, for example, with a flexible outer skin, so that the container can be made to rupture by pressure being applied to it, and the chemical substance contained therein can escape.
  • the inflation mechanism can be connected to the inflatable envelope by means of a valve, and separated from it again after inflation has been carried out. This permits the gaseous substance produced by the chemical reaction to flow into the inflatable envelope and to remain in the envelope after the inflation mechanism has been detached.
  • the inflation mechanism can be connected to the inflatable envelope without using a valve, in which case the inflation mechanism remains connected to the inflated envelope after inflation in order to prevent the gaseous substance from escaping from the inflated envelope.
  • a first chemical substance may contain or consist of a solid, and a second chemical substance may contain or consist of a liquid, and when the substances come into contact, the chemical reaction may consist in the solid being dissolved by the liquid, with the gaseous substance being one of the reaction products.
  • the solid may contain or consist of sodium carbonate (washing soda) or sodium bicarbonate (baking soda), and the second chemical substance may contain an acid.
  • washing soda sodium carbonate
  • baking soda sodium bicarbonate
  • the second chemical substance may contain an acid.
  • gaseous CO 2 is produced as the reaction product.
  • Citric acid practicably as an ingredient of lemon juice, or malic acid may be used as the acid.
  • a different solid which can be dissolved in a liquid may be chosen for the first chemical substance such that a gaseous substance such as CO 2 or O 2 is released when the solid is dissolved in the liquid.
  • the solid may also be provided by a kind of effervescent powder, and the liquid in the simplest case by water, so that the desired result of a chemical reaction, with the formation of a gaseous substance, can likewise be achieved.
  • the solid should preferably be present in the form of a powder or granulate, so that it has as much free surface exposed to the liquid as possible.
  • a handle member in the form of a flexible loop may also be provided at a position on the outer wall of the envelope.
  • the self-inflating umbrella it is possible for the self-inflating umbrella to be folded together in its initial state to a very space-saving size, or for storing it when not in use, since it no longer has any bulky, space-consuming parts.
  • the folded-together form In the folded-together form, it can be carried easily in a jacket or trouser pocket. When needed, it can be activated by applying pressure to the marking on the outer skin of the inflation mechanism so that the chemical reaction is initiated inside it. Due to the vacuum inside the envelope or inside the chambers to be inflated, when in the initial state, the gaseous substance produced by the chemical reaction flows very rapidly into the envelope or chambers and inflates these very quickly, with the result that the umbrella is available within a very short time.

  • the self-inflating umbrella 10 essentially comprises an inflatable envelope 11 made of a flexible material, for example of a suitable plastic material such as polypropylene or the like.
  • a suitable film material may also be used, as an alternative.
  • envelope 11 When not in use, i.e. prior to inflation or after releasing the gaseous substance, there is a vacuum inside envelope 11 , so the envelope can be folded together into a very small space.
  • Envelope 11 is produced in such a way that, when inflated, it adopts the shape of a dome as shown in FIG. 1 , which can be held above one's head as a protection against rain.
  • a loop 13 made of a flexible material is attached to a central portion on the concave side of the dome, through which loop a hand can be placed when in use, so that the umbrella 10 can be held securely and reliably above the carrier's head.
  • the umbrella 10 can be produced in different sizes. In the smallest embodiment, the diameter of the dome is just large enough for the head of the user to be covered. In somewhat larger embodiments, the dome can have a diameter of such size that the shoulder area of the user is covered as well.
  • An inflation mechanism 12 which in a plan view can have a circular or rectangular form, can be mounted on envelope 11 . Production of the gaseous substance for activating and inflating umbrella 10 occurs in the inflation mechanism 12 .
  • FIG. 3 shows a cross-section through a preferred embodiment of envelope 11 .
  • the inflation mechanism 12 can be mounted on connecting piece 14 .
  • connecting piece 14 contains a valve which prevent the gaseous substance from escaping from the inflated envelope after removal of inflation mechanism 12 .
  • connecting piece 14 is mainly used only for establishing the detachable connection to inflation mechanism 12 , for example by means of a screw connection, and that the inflation mechanism remains connected to the envelope as long as the gaseous substance is to stay in the envelope.
  • Connecting piece 14 need not be located on the top side of the umbrella, as shown in FIG. 3 , but may also be mounted centrally on the underside of the umbrella, or on the edge of the umbrella, for example.
  • FIG. 4 shows one embodiment of inflation mechanism 12 in cross-section.
  • a container 12 . 2 containing citric acid or lemon juice is located inside a chamber or envelope. Laterally adjacent to container 12 . 2 , a granulate or powder 12 . 3 consisting of washing soda (sodium carbonate) or baking soda (sodium bicarbonate) is disposed.
  • a marking is applied to the outer side of the chamber or envelope. The outer wall of the envelope or chamber can be pressed in at this marking as far as container 12 . 2 , such that container 12 . 2 can be compressed and made to rupture.
  • marking 12 . 4 the outer skin of the envelope or chamber may be either wholly transparent, or transparent only in the region of container 12 . 2 , so that the user can visually perceive container 12 . 2 and can also observe the gas production process after container 12 . 2 has been forced to rupture.
  • Container 12 . 2 may consist of a small envelope or bag which is shaped out of plastic and filled with citric acid or lemon juice, and which is square in shape and welded together at one or more of its lateral boundaries. When compressed, the envelope preferably tears at one or several of these seams. As is shown in FIG. 4 , suitable precautions can be taken so that container 12 . 2 ruptures on one side only, and hence that its contents escape in one direction only, namely in the direction of the granulate 12 . 3 . As shown, container 12 . 2 may be additionally reinforced at three lateral boundaries. When compressed, container 12 . 2 thus ruptures on the left side only. A production-related seam may be located there, or a predetermined breaking point, such as a perforation or the like, may be alternatively or additionally provided in the outer skin of container 12 . 2 .
  • the inflation mechanism 12 has a connecting piece 12 . 1 with which a connection can be established with envelope 11 , so that the gas released by the reaction can flow out of the inflation mechanism into envelope 11 .
  • connecting piece 12 . 1 is provided with a membrane 12 . 4 .
  • Said membrane 12 . 4 consists of a material which is permeable to the gaseous substance produced by the chemical reaction, i.e. gaseous CO 2 in the present embodiment, or it is provided alternatively with a dense network of pores through which only the gaseous substance can pass.
  • Membrane 12 . 4 is simultaneously impermeable to both the liquid and the granulate.
  • the liquid may, for example, have a surface tension which ensures that it cannot pass through the pores of membrane 12 . 4 .
  • the granulate consists of washing soda, i.e. sodium carbonate with the chemical formula Na 2 CO 3 , or of baking soda, i.e. sodium bicarbonate with the chemical formula NaHCO 3 .
  • the acid used to dissolve the sodium (bi)carbonate granulate is citric acid with the chemical formula C 6 H 8 O 7 .
  • Lemon juice contains 5-7% citric acid, so it is possible in the simplest case for container 12 . 2 to contain lemon juice. Gaseous CO 2 is produced as a reaction product when the sodium (bi)carbonate granulate is dissolved in citric acid.
  • the equation for this chemical reaction is the following:
  • the gaseous CO 2 thus produced escapes very rapidly through the pores of membrane 12 . 4 , via the connection comprising connection pieces 12 . 1 and 14 , into the interior of envelope 11 , thus inflating envelope 11 .
  • the base portion of envelope 11 may have a slightly greater thickness in the region around loop 13 than the rest of the outer skin of envelope 11 , in order to ensure the requisite stability and strength in said region.
  • loop 13 made of flexible material is externally attached to said base portion. Loop 13 preferably consists of a thin, space-saving layer of a suitable plastic material such as polypropylene.
  • the outer edge of envelope 11 is also shown in FIG. 3 . As can be seen, an upper envelope portion 11 .
  • the gaseous substance may be released again from the interior of envelope 11 by opening the valve in connecting piece 14 , or by disconnecting the envelope and the inflation mechanism.
  • envelope 11 can be folded together again, for example to form a square package. Folding is done in such a way that connecting piece 14 remains accessible in the folded state.
  • a new inflation mechanism can be attached to connecting piece 14 either immediately or the next time the umbrella is used, in order to re-inflate the umbrella.
  • the inflation mechanisms are disposable items that can be disposed of after they have been used once.
  • the pack which may be square-shaped, and the trigger mechanism are so small that they can easily be carried in a pocket of an article of clothing. If desired, however, the square pack can be kept with the trigger mechanism in an adapted case, in particular to avoid the umbrella being unintentionally triggered.
  • FIG. 5 shows a perspective view, seen at an angle from above, of a second embodiment of a self-inflating umbrella according to the invention.
  • the self-inflating umbrella 20 has an envelope 21 which is provided with a number of inflatable channels 21 . 1 projecting radially from a central chamber 22 , between which channels single-layered regions 21 . 2 not shaped as envelopes extend.
  • an umbrella 20 of this kind is somewhat more complicated to manufacture, it can be inflated more quickly when used, because only channels 21 . 1 and hence less volume need to be filled with the gaseous substance that is produced.
