Abstract

Inflatable body in the form of a column with a sheath, which is made using a flexible material, for forming or receiving an information carrier, characterized in that the sheath (14) has one or more chambers (8) which are made using the flexible material are manufactured and can be sealed airtight.

Description

The invention is based on an inflatable body in the form of a column with a jacket, which is produced using a flexible material and is used to form or accommodate an information carrier. Such an inflatable body is in the form of an advertising column from the DE 296 17 592 U1 known. This known inflatable advertising pillar is inflated like an air-inflated hall by a blower arranged outside the advertising pillar, which permanently maintains a slight excess pressure in the advertising pillar and thereby stabilizes its shape. If you switch off the blower, the advertising column collapses and can be transported to another location.

The disadvantage here is that for inflation the advertising column relatively large blower is required which has to be taken from place to place and that you have a constantly available energy source for the blower needed. There is an electrical outlet outdoors most not available nearby and laying electrical cables outdoors is always included circumstances connected. if you use an internal combustion engine instead as an energy source, elevated that the scope of the equipment, the carried along Need to become and also creates noise.

The present invention lies based on the task of showing a way such as an inflatable Body, which is used to form a mobile information carrier, in particular in the form of an advertising column, can be simplified in its manageability.

This task is solved by an inflatable body with the features specified in claim 1. Advantageous further training the invention are the subject of the dependent claims.

The inflatable body according to the invention in Shape of a column has a jacket which has one or more chambers which are made using flexible material and are airtight. This has major advantages:

• - The Arrangement of the chambers in the jacket can be chosen so that the body alone erected by inflating the one or more chambers can be.
• - Thereby, that only the one or more chambers of the mantle with air filled Need to become, but not the entire volume of the column, the erection takes place of the body very much much easier. It is sufficient a blower or a pump with a lower performance than in the prior art, so that a lighter and more portable blower or a lighter and more portable pump than in the prior art Technology can be used.
• - It is even possible a column according to the invention in a reasonable way Inflating time with a pump that is operated with muscle power, for example using one of the for Known foot pumps for camping purposes or manually operated pumps.
• - Thereby, it is necessary that the chambers of the jacket can be closed airtight no constantly running fan, around the body to get upright. If necessary, air loss or pressure loss compensated from time to time by pumping again briefly become.
• - There one is not constantly running fan or one constantly running pump required, There is also no need to keep using a blower or a pump To supply electricity. It is sufficient, the current for the short time of filling the chambers in the jacket from a battery or from a rechargeable To remove the battery or from the electrical system of a motor vehicle, with which the inflatable according to the invention body is transported to its respective location. So you can for the short When the vehicle is being erected, the vehicle engine is idling leave when you pull the vehicle battery up for inflation, but wants to spare at the same time. Another option is a charge air blower for inflation, if any, present in the motor vehicle of the inflatable body pull in and the charge air blower with a separately lockable connection fitting to provide.
• - There one is not constantly running fan needed there is after inflating the body no noise more.
• - Thereby, that the one or more inflatable chambers of the shell are made using flexible material, the inflatable body by folding the air out of the chambers to save space and can be easily transported.

For the design and arrangement of the chambers there are numerous options which only have to be based on the purpose of inflating the coat to the chambers in the form of a column stabilize. In the simplest case, the jacket is double-walled and has only one, almost cylindrical chamber, the shape of which is not caused by inflation can be stabilized in that the outer skin and the inner skin of the double-walled Coat are tacked together in places. One more way the additional Stabilization consists of the inner skin of the mantle with stiffening rings to be provided, which extend in the circumferential direction of the jacket.

If there is only one chamber, then this extends over the entire height of the jacket. However, this is not mandatory if there are several chambers, but several chambers or all chambers can also be accessed via the extend the entire height of the jacket, for example in such a way that the chambers run vertically and form a wreath arranged close to each other. A jacket in the form of such a wreath can be further stabilized by providing stiff or rigid end pieces, for example a ring or a plate, at the top and bottom of the jacket, or by the fact that the top and bottom of each an annular, extending in the circumferential direction of the shell, another chamber made of flexible material is provided, which is also inflatable.

An inflatable according to the invention can be collapsed particularly cheaply Body, if several chambers are provided and these are ring-shaped are arranged so that they extend in the circumferential direction of the column, which the jacket forms when inflated, i.e. the longitudinal axis the pillar surround. In this case, when the inflatable body is opened, to let the air escape, just collapse, which advantageously supports this that he wears a headboard, which has a ring, a lid or can be a hat and its weight is sufficient to hold the air from the open To press chambers so that the body automatically folds, until it only contains an insignificant remaining volume of air.

Basically, the coat can be made several wreaths surrounding each other be formed by chambers to increase its dimensional stability. However, it is preferred to form the jacket only double-walled, because already with it for the by far most use cases adequate dimensional stability is achievable.

If annular chambers are provided one above the other, then these are preferably in pairs over their themselves in the circumferential direction extending walls connected with each other. The connection can be that two adjacent chambers have a common partition. The connection can also consist in the fact that the chambers are hoses that are one above the other arranged and, for example, by ribbons which go from top to bottom run down and the hoses surrounded by loops or attached to the hoses, one below the other are connected. The hoses can too connected to one another by, preferably rigid, intermediate rings be glued to the intermediate rings. The hoses can too be directly connected to one another, in particular cohesively Gluing, welding or - in Case of rubber hoses - by vulcanizing. The connection of the hoses can take place in places and preferably takes place along their entire circumference, which results in a particularly stable structure. The hoses are preferred equal to each other, so that you have a coherent, in the large and can form whole cylindrical stack.

The hoses can be on an elastomer Made of material, especially rubber, but they can also consist of a plastic film, for example of polyethylene or made of polypropylene. Hoses made of a composite material can also be used, for example from a textile fabric, which with a plastic soaked or is coated, for example hoses of the type shown by Fire brigades are used and high flexibility, airtightness and firmness towards Combine internal pressure. Rubber hoses can also be used otherwise for pneumatic tires are used, for example tubes for bicycles, motorcycles or motor vehicles. Such rubber hoses can be used Example by gluing or vulcanizing into a coherent Stack connected. T-pieces could be on their valves be screwed, which in turn by pieces of tubing with each other are connected so that the hoses can be inflated at the same time. For a preferably unhindered collapse of a tube consisting of several such tubes It is particularly cheap when coat the hoses no over Valves, but immediately above the hose walls are interconnected. This can be done by making the fluid connection two adjacent hoses is realized at a point where the tube walls are integrally bonded to one another are connected. In this way, the passage that the flow connection establishes, through the material connection enclosing him can be sealed without any special effort.

The places where the hoses or chambers with each other in terms of flow can be connected in principle chosen arbitrarily become. Cheap is to arrange the points so that the hoses or chambers either parallel or in series with each other in terms of flow are connected. With a parallel connection, two adjacent hoses with each other in terms of flow be connected, which leads to a low flow resistance. A flow connection in series is for the process of raising the jacket to the column is advantageous. You lead air first in the top tube, then fill up the hoses progressing from top to bottom and the coat can be special can be easily erected because the first time air is introduced the entire coat does not have to be lifted immediately. Also the easiest way to deflate is by the top one Hose, because the air does not have to squeeze through hoses, which are already compressed under the weight of the column on them.

If the jacket consists of several chambers which are arranged one above the other, then all chambers are expediently in terms of flow connected with each other. However, it can also be advantageous not to connect all the chambers in terms of flow, but to form groups from adjacent chambers and to connect only the chambers of one group in terms of flow. For example, one could group a first group of chambers so that, when filled with air, they form a first section of the column with a certain first height, while a second group of chambers or tubes form a second section of the support with a certain second height , This opens up the possibility of erecting columns of different heights, by either filling only the chambers of the first group or only the chambers of the second group or all chambers with air.

Instead of tubes like those used for pneumatic tires Wheels used , you can also use custom-made hoses, which is different from hoses for pneumatic tires Wheels in it distinguish that they are not a valve, but only two openings or even have only one opening in individual cases. The manufacturing technology, which is to be used here is from the manufacture of tubes for pneumatic tires Known wheels and opposite to the effort for the valves and their installation reduced, so that such hoses inexpensive can be provided.

Instead of endless, ring-shaped hoses for the construction to use the jacket can be in an advantageous development the jacket can also be formed from a single tube of finite length, by winding this hose into a helical structure and along the line of contact the coil at least in places, preferably continuously, with a material bond connecting itself. Such a structure is particularly suitable for one rational, continuous production, in the course of which the hose over a Support body with the desired one Diameter wrapped and during of the winding continuously connected to itself be it by gluing, by welding or by vulcanization. A jacket constructed in this way can be chosen from the upper end or from lower end of the hose or from both ends of the hose befalls and be emptied.

The flexible material from which the chambers formed can be elastic, but it can be practically non-stretchable even under the air pressures to be used, for example when the jacket is made up of fabric tubes becomes. The chambers are made with the help of flexible, rubber-elastic Material is formed, then the outer diameter can be filled in by pressure of the coat increased become. This is beneficial when it comes to the coat a flexible cover to fix, which serves as information carrier or in turn one information carrier records because the shell can then be tightened by pumping up the jacket, with a certain overpressure can be set to for space despite unavoidable air loss Time to ensure a tight fit of the flexible cover. Such a flexible Shell can just about put on the not yet inflated coat and straightened up with it and be tightened. The case can be printed with information immediately. The shell can but also just serve as a means to get the coat through its structure of chambers can have a wavy outer contour and in this way create a smooth cylindrical surface on which then Information can be applied or about the another shell that can be printed with information, can be drawn. The inner one shell which covers a ripple emanating from the chambers a loose shell be, but it can also be connected to the chamber walls, in particular cohesively, and, in conjunction with the chambers, form the mantle that is inflated or inflating to the column is erected; such a bond between the chamber walls and the inner shell has the advantage that it contributes significantly to the dimensional stability of the column.

In an advantageous further training of the invention is the inflatable body, especially its coat, transparent or translucent. That makes it possible in to provide a lamp inside and the information carrier which through the outside of the jacket is formed or, in particular as a separate shell the outside of the coat is brought to illuminate from the inside.

The inner shell can be rubber-elastic and therefore be stretchy, which allows to punish a second cover. The inner shell can but also consist of a practically inextensible material. Instead, could the outer shell is stretchy be and therefore be tightened. However, this is not mandatory.

In order to be able to set up a body according to the invention in the manner of an advertising column, the jacket is expediently connected to a foot part, which can have the function of a stand. It is particularly advantageous if the foot part is rotatably mounted on a stand, so that the body according to the invention can be used as an inflatable, rotatable advertising column. The rotary movement can be brought about in different ways, for example by providing a motor. This can be a small electric motor that does not require a lot of electricity because the rotating body is light and only needs to be rotated slowly. The motor, which is expediently provided on the stand, can therefore be supplied for a long time from an accumulator, for example from a vehicle battery. Another way to make the body spin is to take advantage of air movements Zen. For this purpose, a wind wing can be provided on a head part of the body, which is non-rotatable relative to the jacket or can be fixed in order to achieve non-rotatability. With such a wind vane, the body can be rotated on its stand. If the non-rotatable coupling between the wind wing and the jacket can be released, then the wind wing can also rotate on its own, thereby attracting attention and a special advertising effect.

For a mobile use of the body according to the invention is particularly important Advantage if the foot section Has means for anchoring on a mobile base, namely not necessarily for the transport, but for anchoring the erected column. A body according to the invention can be used for Example anchored on the roof of a vehicle or on a vehicle trailer on the vehicle roof, for example with the help of a pedestal, which like a roof rack on the Vehicle roof can be anchored. The body can on the roof, at least if it is folded up after deflating, also transported and erected at its place of use by pumping up to Example using one operated by the vehicle electrical system Pump or with the help of an intercooler in the vehicle.

The body according to the invention preferably has a Head part, which can be designed as a ring, lid or hat. Such a headboard is advantageous in several ways because it the interior of the body shields, the shape stabilizes and when the air is deflated Escape supported, because it presses on the chambers from above.

To continue building the body to stabilize, it is advantageous if the headboard and footboard go through collapsible distance limiters are connected, in particular by cords, Ropes or tapes, which hold together the arrangement of headboard, footboard and jacket limit their expansion upwards. The distance limit can don't just serve to inflate the inflatable sheath by bracing it the headboard against the footboard to put pressure and thereby stabilize, but also to the height to vary up to which the body is erected by inflation becomes. You can do this the distance limiters, for example cords, with a selectable length before inflating the foot part and the headboard. When inflating the jacket can the body then only straighten up to the specified height. It does it possible, the body adapt to its respective purpose. For example, he can for the Use on a vehicle reduced in height and for one stationary Use at height be enlarged.

Three embodiments of the invention are schematically in the attached Drawings shown in which the same or corresponding to each other Part with matching Reference numbers are designated:

1 shows a vertical section through a first embodiment of an inflatable advertising column,

2 shows a cross-section AA through the in 1 illustrated inflatable advertising pillar,

3 shows a vertical section through a second embodiment of an inflatable advertising column,

4 shows a vertical section through a third embodiment of an inflatable advertising column, which is rotatably installed, and

5 shows a plan view of a wind wing according to 4 ,

This in 1 illustrated embodiment has a foot part 1 with a circular plate 2 which have a raised margin 3 and several angled feet 4 which is at the bottom of the plate 2 attached and there with a horizontal leg 4a in radial rails 5 are led. The thigh 4a the feet 4 can be extended radially a bit and thereby increase the stability.

On the plate 2 there is a stack of hoses 6 which are interconnected by vulcanization. The vulcanized areas are with the reference number 7 designated and preferably have a width of a few centimeters. The hoses 6 form superimposed chambers 8th which one another through openings 9 in the hoses 6 are connected in terms of flow. The openings 9 are in the vulcanized areas 7 and have a diameter which is smaller than the width of the vulcanized area 7 so the openings 9 from the surrounding vulcanized areas 7 are hermetically sealed. On the top hose 6a is a flexible hose-shaped supply line 10 attached, which through a hole in the plate 2 is led to the outside. The lower end of the supply line 10 is with a valve 11 through which the hoses 6 can be filled with air and through which the air can also be released.

Over the stack from the hoses 6 is an envelope 12 pulled the diameter of the erected into a column from the hoses 6 formed coat 14 limited and a ripple that the coat 14 exhibits, balances. The case 12 has a radially inward end edge at its upper end 15 with a clear width that is smaller than the outer diameter of the jacket 14 , preferably approximately the inside width of the jacket 14 is equal to.

The coat 14 is through a headboard 16 covered, which is curved so that rainwater can drain off, and which has a downwardly extending edge 17 with which it has the top hose 6a overlaps. At the bottom of the headboard 16 are three flexible, thin ropes 18 buildin which holes through them 19 in the plate 2 of the foot part 1 led outwards and at the bottom of the plate 2 are tensioned, for example by the fact that at the lower ends of the ropes 18 threaded rods 20 are attached, which through the holes 19 in the plate 2 protrude. If you turn wing nuts 21 on the threaded rods 20 , the ropes 18 curious; excited.

The hoses 6 and the shell 12 are made of translucent material. A lamp 13 which is at the bottom of the headboard 16 is attached and can be supplied, for example, from a vehicle battery, can therefore an information carrier, which on the case 12 can be applied, illuminate from the inside.

This in 3 illustrated embodiment differs from that in the 1 and 2 illustrated embodiment in that the jacket 14 is not formed by a stack of tubes, but by a single tube 6 , which is wound into a helical structure, the stabilization taking place, as in the first exemplary embodiment, in that the turns of the hose 6 along a strip-shaped area 7 are glued or vulcanized to one another, which correspondingly extends helically through the helical structure. Another possibility of stabilization would be the turns of the hose with the sleeve 12 connect to. It is also possible to combine both types of connection with one another.

By tightening the headboard 16 against the foot part 1 can despite the helical turn of the hose 6 a horizontal position of the headboard 16 can be achieved. To facilitate this, there is also the option of placing the hose on the last turn 6 a compensating body 23 to fix.

For filling the hose 6 is a supply line at its upper end 10 provided which, as in the first embodiment, by a valve 11 is lockable. The lower end of the hose 6 is closed.

This in 4 illustrated embodiment differs from that in 1 illustrated embodiment in that the foot part 1 by means of a pivot bearing 24 rotatable on a stand 25 is stored. It is driven by a wind vane 26 which is on the headboard 16 is attached and takes it with it when it is rotated by wind.

The ropes 18 are eyelets in this case 27 attached, which in turn on the foot part 1 are attached. The top ends of the ropes 18 are through holes in the head part 16 passed through and by clamps 28 which is on the top of the headboard 16 are provided. With the terminal open 28 can the between the foot part 1 and headboard 16 effective length of the ropes 18 changed and thereby the height of the advertising column which is set when inflating can be predetermined.
