Description

The technical solution concerns statutes with inflatable load-bearing structure, especially statutes from technical textiles, such as work, rescue, military, humanitarian and other purpose tents.

BACKGROUND OF THE INVENTION

Tents normally comprise a supporting structure, beams, of solid material. As tents are mostly intended for temporary use only, their transport and construction time are problematic in this case. In order to overcome these drawbacks, solutions of supporting structures of inflatable tubes, whether permanently inflated or airtight, are known.

In the case of permanently blown beams, the problem is the low operating pressure (approx. 1 kPa) and the associated large diameter of the beams, as well as the need for permanent air blowing.

The operating pressure in the airtight beams is generally 15 to 40 kPa, which greatly helps to reduce the diameter of the beams. Due to their construction, however, higher pressure is undesirable (destructive) and therefore it is necessary to equip such beams with pressure relief valves. On sunny days, it is common for the increased pressure resulting from the increase in air volume to be compensated by pressure relief valves. However, the escaped air is missing in the cold night hours and stand, respectively. its supporting structure collapses.

Seamless beams with higher operating pressure appear to be most advantageous without the need to compensate the pressure with the pressure relief valves. There are already solutions on the market that apply the principle, but the beams used are usually tailor-made with special technologies, which disproportionately increases the total cost they become.

It would therefore be advantageous to use existing elements capable of withstanding high operating pressure as beams. Such elements appear e.g. fire hoses that are commonly available. The use of fire hoses as beams of the roof structure is disclosed in EP 0810339. This solution makes it possible to create a temporary roofing by means of a structure comprising inflatable beams, preferably formed from fire hoses. These hoses are connected at the ends to fixed support elements arranged in a row. When creating an overlap of the space, fixed support elements are placed on the edges of the space to be covered, which at the same time serve as air distribution elements in said hoses. Hoses are connected to these support elements with respective ends which, after inflation, form an arc between said support elements. series of arches. An overlap sheet is then attached to this row of arches. This solution creates an arched overlap on the open ends (tunnel), and is not suitable for tent structures due to the support system used.

The object of this technical solution is to become an inflatable supporting structure taking advantage of the use of standard fire or other industrial seamless hoses with outer textile braid and inner airtight liner as inflatable elements of the supporting structure while maintaining the simplicity of the specified structure, especially in terms of composition and layout.

The essence of the technical solution

This object is achieved by an inflatable load-bearing tent according to the present invention, which comprises an outer shell and a floor part, characterized in that the inflatable load-bearing structure comprises at least one beam formed from a standard fire or other industrial seamless hose with an outer textile braid, wherein the hose is closed at each end by a plug of which at least one comprises an air inlet / outlet element, and at least one end of the hose is attached and / or supported on the outer sheath and / or the floor portion becomes.

Hoses inside the tent can be arranged in all directions (longitudinal, transverse and diagonal) according to the shape predefined by shearing the outer shell and the floor part. In case of cross-over of the hoses, the hoses can be divided into relatively shorter sections and the respective ends of the hoses, respectively. the plugs at the respective ends of the hoses can be connected to the connecting element or the hoses can only be freely crossed.

Preferably, the air inlet / outlet element is located on the bottom or side wall of the hose plug. The air inlet / outlet element may be formed as a separate air inlet element and a separate air outlet element, but may also be formed in one.

The essence of the technical solution is, in other words, the adaptation of standard fire or other industrial seamless hoses with an outer textile braid and an inner airtight lining into a mold. Because the sheath is standing and the floor part generally forms a single unit or the ends of the hose are anchored to the floor part, the hose is formed into a substantially arcuate shape when inflated, in particular according to the shape predefined by the adapted cuts of the outer sheath and floor part.

Use of standard fire or other industrial seamless hoses with external textile

SK 6715 Υ1 braids and inner airtight liner allow higher operating pressure without pressure relief by pressure relief valves. Thus, the shape and overall size of the supporting structure become defined and unchanged even under pressure fluctuations caused by a change in temperature or pressure of the external environment.

EXAMPLES

In FIG. 3 shows an embodiment with a tunnel-shaped inflatable structure. In this exemplary embodiment, the stand comprises an outer shell 1 coupled to the floor portion 2 having a corresponding cut for the tunnel shape to become. It will be appreciated that the floor portion 2 may be formed as a whole, the floor sheet as well as the split sheet, e.g. for belt elements. The tent inside contains separate inflatable beams arranged in a row. The inflatable beams consist of a standard fire or other industrial seamless hose 3 with an outer textile braid. As shown in FIG. 1 and 2, the hose 3 is closed at each end by a plug 4. At least one of the plugs 4 comprises an air inlet / outlet element 5. Such air inlet / outlet elements are commonly known and available, e.g. various manual or automatic air valves. In the exemplary embodiment, they become the inflatable structure of FIG. 3, the hose 3 is in the inflated state supported by both ends, i. j. With the plugs 4 and possibly the end portion of the hose 3 by the floor portion 2, the bottom becomes and the outer sheath 1 at this floor portion 2. By defining the distance between the ends of the hose 3 by the size of the floor portion 2 less than the length of the hose 3 the floor part 2 and the outer casing 1 near this floor part 2 and form an arched inflatable beam to become the outer casing 1 become. The outer sheath 1 can be additionally attached to the hoses 3 by known methods, but even without additional fastening, the thus formed stand is sufficiently stable and strong. The inflation of the hose 3 is effected by means of the filling / discharge elements 5, which in this exemplary embodiment according to FIG. 2 located on the side of the respective plug 4. The hoses 3 contained in the inflatable structure can also be connected via said inlet / outlet elements 5 to a single pneumatic assembly for easier inflation and deflation of the support structure.

In FIG. 4 shows an embodiment of a tent with an inflatable structure, a dome shape with crossed beams, hoses 3. In this exemplary embodiment, the tent comprises an outer casing 1 connected in one piece to the floor part 2 having a corresponding dome shape of the tent. As in the previous embodiment, the floor part 2 can be formed as a whole, the floor sheet as well as the split sheet, e.g. for belt elements. The beams of this tent are formed by hoses 3, wherein one end of the hose closed by the plug 4 is supported on the floor part 2 and the outer casing 1 at this floor part 2 and the other end of the hose 3 closed by the plug 4 is connected to the connecting element 6. such that the plugs 4 and the connecting element 6 are made as one unit. The connecting element 6 may have different shapes and arrangements, which depend in particular on the number of hoses 3 in the joint and the angle of intersection of the hoses 3. The most common shapes are e.g. X and T. The corresponding plugs comprise an air inlet / outlet element 5 analogously to the previous example. The principle of forming an arched beam is analogous to the previous example when the hoses 3 are inflated.

It is, of course, possible to cross hoses 3 without using the connecting element 6. For example, for the particular embodiment shown, the coupling element 6 is not used and the hoses 3 cross each other without interruption.

In the exemplary embodiments, the resultant shape of the hoses 3 was achieved by spreading them inside to become the circumference of the outer shell 1 and the floor part 2. Such an arrangement is most advantageous to meet the stated objective of the present invention.

Fig. 5 shows an embodiment of a plug 4 of a hose 3 with a fastening element 7 for fastening to a floor part 2. When carrying out a technical solution with such a type of plug 4,

SK 6715 Υ1 to form anchoring elements 8 at the required spacing, distances, to which the fastening element 7 of the plug 4 is connected. The desired expansion of the hose 3 is then achieved by gripping the plug 4 in the anchoring element 8 on the floor part 2. In this case, it is not even necessary to directly connect the outer casing 1 to the floor part 2, but such a solution no longer provides all the preferred advantages of this solution.

The connection of the plug 4 to the hose itself is possible by conventional methods of making the connection of the plug to the end of the hose.

The examples given are for illustrative purposes only to explain the principle of this invention. Obviously, by using the principles outlined in this technical solution, it is possible to create a large number of shapes and combinations of tents with an inflatable supporting structure. Obviously, such further embodiments of the inflatable structure of the present invention are then determined by the shear and individual dimensions of the outer shell 1 and the floor portion 2, the lengths of the hoses 3 and the methods of crossing and combinations of these hoses 3, all within the scope of protection defined by the claims. for protection.

For this technical solution, air is considered as the most available gaseous medium as an inflation medium. However, it is understood that other suitable inert gases such as e.g. nitrogen or CO ₂ .

Industrial usability

The tent with an inflatable supporting structure according to this technical solution can be used wherever good storage and transportability, as well as the speed of positioning of the object is needed, preferably the stability of the inflatable supporting structure, especially with regard to changing environmental characteristics, especially temperature and pressure.
