Definitions
- the present invention relates to an inflatable umbrella.
- the prior art discloses that one objective in improving the handleability of screens is to reduce their bulkiness, i. reduce the number and / or size of bulky parts in screens.
- the bulkiness of conventional umbrellas is based in particular on the grip part, the central support rod and the fabric strut spanning radial struts. It must therefore be a goal of further developments to replace these elements with other, functionally approximately equivalent elements.
- a screen which has an inflatable shell, which assumes the shape of a hood in the inflated state.
- the hood can be held over the head of a user for protection.
- a gaseous substance can be generated by a chemical reaction, which serves to inflate the shell.
- a very high rigidity of the same can be achieved by a very high pressure in an inflatable casing. Since the inflatable casing may not be very thick, so that it is not too heavy and does not require much space in a folded state, the pressure can not be arbitrarily large. Thus, there is the problem in the previously known inflatable umbrellas that they do not have the necessary stability in an inflated state to withstand greater external forces such as forces caused by stronger wind or rain forces can.
- the object of the present invention is to provide an improved inflatable umbrella, which in an inflated state is more stable and resistant to external forces than previously known umbrellas.
- a screen comprises an inflatable envelope made of a flexible material.
- the latter forms at least the following elements: a central retaining element, at least three shield strut elements extending away from the central retaining element, and at least one shielding surface element spanned by the shield strut elements.
- the central holding element and a respective umbrella strut element are based on their respective contact point against each other.
- the central holding element By supporting the central holding element and the umbrella strut elements against each other, on the one hand, the central holding element is centered, vertically aligned and stabilized. On the other hand, a stable alignment of the Schirmstrebenieri is effected. Self-locking structures independently build up the static. As a result, overall greater stability and resistance to external forces such as wind forces or forces caused by incident rain is achieved.
- two adjacent umbrella strut elements are supported against each other at their respective contact point.
- further stabilization of the glider and, in particular, greater resistance to laterally applied forces, e.g. Wind forces are achieved.
- an imaginary center axis of a shield strut element intersects an imaginary central axis of a shield strut element adjacent to a first side outside an imaginary central axis of the strut element central retaining element.
- each shield strut element extends laterally offset next to the central holding element.
- the ends of the umbrella strut elements facing the central retaining element are grouped around the central retaining element in such a way that it is centered, vertically aligned and stabilized, and overall greater stability of the umbrella is achieved.
- an imaginary center axis of a shield strut element and an imaginary center axis of a shield strut element adjacent to a first side are skewed and a shortest path between the imaginary center axis of the shield strut element and the imaginary central axis of the umbrella strut element adjacent to the first side intersects an imaginary central axis not the central holding element.
- each shield strut element extends laterally offset next to the central holding element.
- the ends of the umbrella strut elements facing the central retaining element are grouped around the central retaining element in such a way that it is centered, vertically aligned and stabilized, and overall greater stability of the umbrella is achieved.
- a shield strut element and a shield strut element adjacent to a first side are abutted against each other at a contact point located at an end of the shield strut element facing the first side and the shield strut element and a screen strut element adjacent to a second side are supported against each other at a contact point which is located on an end of the screen strut element which is adjacent to the screen strut element and which is adjacent to the second side.
- the umbrella strut elements are supported against each other so that they are stably aligned. Greater resistance to lateral forces is achieved.
- a cross-sectional area of the central holding element increases in a penultimate portion of the central holding element in front of the screen strut elements and decreases in a last section of the central holding element in front of the screen strut elements and a cross-sectional area of a respective umbrella strut element increases in a penultimate portion of the respective umbrella strut element in front of the central holding element and decreases in a last section of the respective umbrella strut element in front of the central holding element.
- the central holding element or the umbrella strut elements are stiffer and more stable.
- an end of the central holding element facing the umbrella strut elements is substantially pyramid-shaped, wherein a cross-sectional area of the central holding element forms a base of the pyramid and the respective contact point of the central holding element and the respective umbrella strut element is in each case on a side surface of the pyramid.
- an end of a respective screen strut element facing the central holding element is substantially pyramid-shaped, a cross-sectional area of the respective shield strut element forms a base area of the pyramid, the respective contact point of the respective shield strut element and the central holding element is located on a first side face of the pyramid, a contact point of the respective umbrella strut element and a shield strut element adjacent on a first side is on a second side surface of the pyramid, and a contact point of the respective strut strut element and a screen stripping element adjacent on a second side is on a third side surface of the pyramid.
- the screen comprises a compressible material and a valve, and by compressing the compressible material, a gaseous substance for inflating via the valve is suckable and can be supplied to the interior of the inflatable envelope.
- a gaseous substance for inflating via the valve is suckable and can be supplied to the interior of the inflatable envelope.
- the screen can be quickly filled with the gaseous substance. If the screen is folded after its manufacture under vacuum or in vacuum, the volume of the compressible material can be minimized and so a small extent of the collapsed screen can be achieved.
- the compressible material is surrounded by a sheath of a flexible material connected at one end to the valve and forming at the other end a tube valve, the gaseous substance being inside the inflatable sheath can be supplied via the hose valve.
- the hose valve is controlled by a pressure in the interior of the screen or the inflatable shell and thus allows in conjunction with the valve inflating the screen.
- the compressible material is a material having a foam structure that is successively compressible by increasing pressure in the inflatable shell such that pumping power achievable with the compressible material decreases and no over-pressure is created in the inflatable shell ,
- the build-up internal pressure causes a deliberate reduction of the pumping power, which automatically prevents exceeding a maximum allowable pressure.
- the compressible material is included in a grip part of the central holding member a changed cross-sectional area arranged and compressible by pumping movements of a user's hand. This optimally utilizes the shape of a hollow hand and achieves a high pumping capacity.
- At least two chemical substances are arranged separately from one another in the inflatable casing, a chemical reaction being triggered by their contact with one another, whereby a gaseous substance for inflating can be produced. In this way, automated inflation is possible with simple means.
- the umbrella has a telescopic handle
- the inflatable shell is located in the telescopic handle prior to inflation, and inflation is effected by pumping movements of the telescopic handle.
- the inflatable shell has at least one valve and is inflatable and / or deflatable via the valve. So a user can inflate the screen at any time with the mouth and emptied again.

- the central holding element 110 or 510 has a compressible material 705 and a valve 7 0 in an area in front of its end facing away from the shield strut elements 115, 120, 125, 130 and 515, 520, 525, 530, 535, 540, respectively wherein the compressible material 705 and the valve 710 may also be disposed at another location of the screen 100 and 500, respectively.
- the volume of the compressible material 705 can be minimized, thus achieving a small expansion of the folded screen 100 or 500.
- the compressible material 705 may be surrounded by a sheath 715 made of a flexible material, which is connected at its lower end to the valve 710 and at its upper end a hose valve 720 formed by a pressure in the interior of the inflatable shell 105 and 505 is controllable.
- the valve 710 may be a check valve, such as a diaphragm valve, which may be formed of a soft membrane and a membrane holding device.
- hose valve 720 another type of valve may be provided at the upper end of the sheath 715. For example, at this point also a diaphragm valve can be used.
- a gaseous substance for inflating the inflatable sheath 105 or 505 can be sucked in via the valve 710 and supplied to the interior of the inflatable sheath 105 or 505 via the hose valve 720.
- the gaseous substance is typically the ambient air. Downstream air is supplied through the valve 710 and shut off. This process is illustrated in FIG. 7 by two arrows 725, 730, which symbolize the compression, and two arrows 735, 740, which symbolize the suction and the feed of the interior of the inflatable envelope 105 or 505 via the tube valve 720.
- the compressible material 705 may be a material having a foam structure. It may be, for example, normal foam.
- a pressure in the inflatable envelope 105 or 505 increases, the compressible material 705 is gradually compressed by this increasing pressure. Due to this successive compression of the material due to the increasing pressure within the inflatable shell 105 or 505, a pumping capacity achievable with the compressible material 705 gradually decreases and no overpressure can arise in the inflatable shell 105 or 505.
- the internal pressure building up in the inflatable shell 105 or 505 during inflating causes a deliberate reduction of the pumping power, which automatically prevents exceeding of an allowable maximum pressure.
- the compressible material 705 may be disposed in the handle portion 55 or 575 of the central support member 10 and 510, respectively, and be compressible by pumping movements of a user's hand.
- the shape of a hollow hand can be optimally used.
- the user can first inflate the screen 00 or 500 by repeated compression of the grip part 55 or 575 and hold the screen 100 or 500 on the grip part 155 or 575 after inflation. It is for both the inflation and for the subsequent holding advantage if the handle 155 and 575 is ergonomically shaped and fits well in the user's hand.
- the screen 100 or 500 has a telescopic handle 800 with at least two segments.
- the telescoping handle 800 illustrated in FIG. 8 there are three segments 805, 810, 815.
- the telescopic handle 800 is provided at its lower end with a valve 820.
- a gaseous substance for inflating the inflatable envelope 105 or 505 can be sucked in via the valve 820 and supplied to the interior of the inflatable envelope 105 or 505.
- the inflatable shell 105 or 505 is located in the telescopic handle 800 prior to inflation.
- Fig. 9 shows a cross-sectional view of a third alternative inflation system for the screen 100 or 500 according to the first or second embodiment.
- at least two chemical substances are arranged separately in the inflatable envelope 105 or 505, which cause a chemical reaction upon contact with each other.
- a gaseous substance for inflating the inflatable shell 105 or 505 is generated.
- the gaseous substance is distributed in the inflatable shell 105 or 505, whereby the screen 00 or 500 is inflated.
- a first chemical substance 910 is arranged in a container 905, such as a bag made of a flexible material.
- the first chemical substance 910 may contain or consist of a liquid.
- the liquid may be, for example, an acid such as, for example, citric acid, formic acid, tartaric acid, malic acid, succinic acid, amidosulfuric acid or fumaric acid.
- a second chemical substance 915 is arranged.
- the second chemical substance 915 may contain or consist of a solid, which solid may be in the form of a powder or granules.
- the solid may be, for example, sodium carbonate (soda) or sodium bicarbonate (soda).
- the container 905 By pressing the inflatable shell 105 or 505 at a corresponding point, the container 905 can be compressed such that it bursts. Thereby, the first chemical substance 910 may leak out and come in contact with the second chemical substance 915.
- a chemical reaction can be triggered, by which a gaseous substance is generated to inflate.
- gaseous carbon dioxide arise.
- the container 905 and the second chemical substance 915 may be surrounded by a membrane 920.
- the membrane 920 ensures that after the bursting of the container 905, the first chemical substance 910 comes into contact with the second chemical substance 915 in a targeted manner and as completely as possible. It prevents the first chemical substance 910 or the second chemical substance 915 from leaking into the interior of the container inflatable shell 105 or 505 outside the membrane 920 and is permeable to the gaseous substance generated in the chemical reaction.
- a cartridge or capsule which is a gaseous substance for inflating contains.
- a gaseous substance such as carbon dioxide, nitrous oxide, nitrogen or compressed air come into question.
- the central retaining element in each case has an ergonomically shaped grip part with a changed cross-sectional area in an area in front of an end of the central retaining element facing away from the umbrella strut elements.
- a handle part is not required. It is also possible to realize a screen with a central retaining element whose cross section is constant in a region in front of an end of the central retaining element facing away from the umbrella strut elements.
- the present invention relates to an inflatable umbrella 100 and 500, respectively.
- the umbrella 100 and 500 respectively, comprise an inflatable shell 105 and 505, respectively, of a flexible material.
- this forms at least the following elements: a central holding element 110 or 510, at least three umbrella strut elements 115, 120, 125, 130 or 515, 520, 525, 530, 535, 540 extending away from the central holding element and at least a screen surface element 135, 140, 145, 150 or 545, 550, 555, 560, 565, 570 spanned by the umbrella strut elements.
- the central retaining element 110 or 510 and a respective umbrella strut element are based on their respective contact point 425, 430, 435 , 440 and 635, 640, 645, 650, 655, 660 against each other.
- the screen 100 or 500 In the inflated state, the screen 100 or 500 has a higher stability and resistance to external forces compared to previously known inflatable umbrellas.
