    Description FIELD OF THE INVENTION
    The present invention relates to a temporary landing pad for helicopters, deployable fiber reinforced plastic plates and connectors for a temporary landing pad for helicopters, and a method for producing a deployable fiber reinforced plastic plate.
    BACKGROUND OF THE INVENTION
    In order to allow the temporary use of not specially adapted vehicles on soft ground, systems of shims or mats are used for civilian and military purposes. There are, for example Unterlegsysteme braided plastic mats with reinforcing rods made of metal known that must be braced in order to be optimally resilient. These braided mats can be, as long as the rods have not been bent during use, roll well and save space, but they pollute heavily on wet ground and are full of water and mud. This complicates both the removal and the cleaning of the mats.
    Although other Unterlegsysteme, for example, from perforated or honeycomb stiffened metal sheets, in particular aluminum sheets, do not have to be braced, but they have the disadvantage that they are hardly elastically deformable. If they are bent during use, for example on uneven ground, the connections between the individual elements often can no longer be released, and the bent elements can only be stacked poorly, which in turn makes their quick and easy removal and reuse difficult or impossible power.
    Further known are reusable lightweight track systems for sandy shores and shores, which under the name MO-MAT system by AIR LOG Ltd. were offered. These roadway systems consist of individual panels of about 6 m2, which can be detachably connected to each other. The individual panels consist of several layers of resin impregnated parallel fiberglass fabrics that have been pressed at high temperatures under high pressure. The plates have a waffle-like or egg-carton-shaped structure, good load-distribution properties and are very tensile and durable. The glass fibers run parallel to one another within the individual layers. In the top view, the longitudinal axes of the fibers of adjacent layers intersect at right angles, that is, in planar projection, all fibers run in only two spatial directions. The panels with this construction are suitable as temporary lanes on unusually yielding and unsafe soils, such as sand, mud, snow or underwater roadway. Over the years, the panels were also used to construct temporary helicopter landing pads or ramps for watering boats, taxiways and storage areas.
    From EP 0 901 897 A1 there is known a stable, highly resilient shim which is particularly well suited for use as a temporary pavement on unusually resilient and unsafe ground, such as e.g. Sand, mud or snow is suitable. The stable shim is a glass fiber reinforced plastic plate with regular, knob-like positive and negative elevations, which are preferably arranged so that the plates are overlapping form-fitting overlapping. The panels have a multilayer construction of sections of glass fiber-fabricated sections of endless mats sandwiched in a resin matrix. To produce the stable shims, the mats are laid directly into the metallic mold. So that the fiberglass mats can be draped well in the mold, and the home production process can be well adapted to the knob-like positive and negative elevations, the fiber bundles of each mat are loosely sewn together. Since the glass fibers can not be stretched, the good drapability is an essential prerequisite to avoid damage to the fibers and the fiber strand and an uneven surface distribution of the fibers in the finished product. A disadvantage of the known method is that in the production of large plates with an area of up to 8 to 15 m2, the tools must be dimensioned correspondingly large. In addition, a considerable time and thus cost associated with the manufacturing process. Also, this method has a low variability with respect to the size of the fiber-reinforced plastic plate to be produced.
    WO 2014/033 264 A1 describes a method for producing a fiber-reinforced plastic plate, in particular a fiber-reinforced plastic plate with regularly arranged positive and negative elevations. The method comprises the steps of: a) providing a sheet of fibers impregnated with a plastic matrix, the sheet having a front and rear end in the longitudinal direction; b) inserting a first portion of the sheet longitudinally into a working area of a molding apparatus starting from the front end of the textile fabric; c) machining the inserted portion of the fabric by sequentially closing portions of the working area of the molding apparatus such that the portions of the work area are transverse to the longitudinal direction extending from the center closed sequentially outwardly on both sides; d) opening the working area of the molding apparatus and feeding a next portion of the sheet longitudinally into the work area by at least partially removing the preceding portion from the work area; e) repeating steps c) and d) until a final section at the rear end of the fabric is processed and the fiber reinforced plastic sheet can be removed from the molding apparatus.
    PRESENTATION OF THE INVENTION
    As the weight of heavy vehicles, helicopters, or airplanes has greatly increased in recent decades and may even further increase, it is desirable to increase the load capacity of temporary shims and shims assembled by panels without the panels significantly become heavier, stiffer or thicker.
    It is therefore an object of the present invention to provide a temporary landing site, especially for helicopters, which improves the state of the art.
    This object is achieved by the features of the independent claims. Advantageous embodiments of the invention are given in the dependent claims and in the present description and the figures.
    The invention relates to a temporary landing pad for helicopters comprising at least two deployable fiber reinforced plastic plates, as well as connectors for releasably connecting adjacent plastic plates. The plastic plates each have an inner region and a circumferential, outer region, wherein the inner region has regular positive and negative elevations, and the outer region has first and second overlapping regions, which respectively extend along two edges of the plastic plate and openings for receiving the Have connector. The first overlap region is offset from the second overlap region by at least one thickness of the overlap regions. The first or second overlapping regions of a plastic plate can be overlapped in each case with second or first overlapping regions of an adjacent plastic plate such that the openings are aligned and the connectors can be brought into engagement with two overlapping openings in a positive and / or non-positive engagement.
    The temporary landing site has the advantage of a relocatable pad surface, which has a high load capacity and a lower weight compared to solutions of the prior art. The overlapping areas with the openings and the connectors offer the advantage of a reliable connection between the plastic plates, which avoids unintentional release of the plastic plates even at high loads, compared to the known solutions of the prior art, in which the plastic plates only on the positive - And negative surveys are overlapping laid. The plastic plates are advantageously designed such that the landing site can be extended as desired by connecting additional plastic plates. In connection with this invention, it is understood that at least two plastic plates as the smallest unit can form a temporary landing site, which can be extended if necessary.
    Depending on the application, the overlapping areas can be dimensioned differently, which offers increased flexibility with respect to the reliability of the connection between the plastic plates. Further, it is possible to increase the number of openings, if a stronger connection between the plastic plates is desired. In addition, the reliable and easy connection between the plastic plates allows to operate with smaller sized plastic plates, as these can be easily assembled to a landing site of the desired size. The smaller size of the plastic sheets offers advantages for the production because smaller dies can be used. Further, this can be simplified handling and transport. The positive and negative elevations offer the advantage of improved retention of the plastic sheets on the substrate on which the plastic sheets are laid.
    In one embodiment, the first overlap regions are arranged at the same height as the negative elevations and the second overlap regions are arranged at a height between the positive and negative elevations. Preferably, in composite plastic sheets, the first overlapping areas are located below the second overlapping areas, i. The first areas of overlap lie essentially on the substrate on which the plastic panels are laid. By arranging the second overlapping areas at a height between the positive and negative elevations, it can advantageously be achieved that a connector inserted into the openings of the overlapping first and second overlap areas does not protrude slightly beyond the positive elevations, so that the connectors are above the temporary elevations Landing ground rolling landing gear does not stand in the way.
    Preferably, the connectors are brought in from the openings of the second overlap areas and have on the introduction side a height which is less than or equal to the positive elevations. Optionally, the inserted connectors have a height on the introduction side, which projects beyond the positive elevations of the plastic plate by less than two thicknesses of the plastic plate in the overlapping regions. Since it is usually desirable to first lay the plastic sheets and then join the plastic sheets together, it is advantageous if the connectors can be inserted from the openings of the second overlapping areas, which are preferably located above the first overlapping areas. By the height of the connector on the introduction side, which is preferably less than or equal to the positive elevations, can be advantageously achieved that the connectors do not stand in the way of rolling over the temporary landing field landing gear.
    In one embodiment, the plastic plates each have a contiguous first and a contiguous second overlap region, which in each case over two adjacent edges of the respective
    Plastic plates extend. This embodiment advantageously allows a simple and fast scale-like installation of the plastic sheets.
    In one embodiment, the fibers of the plastic plates are selected from the group of glass fibers, carbon fibers, basalt fibers, aramid fibers, polyethylene fibers or combinations thereof.
    In one embodiment, the plastic plates on a matrix comprising a thermoplastic, preferably polypropylene or a polyamide.
    In one embodiment, the plastic plates have a thickness between 2 mm and 12 mm, preferably between 3 and 9 mm, more preferably between 3 and 6 mm.
    In one embodiment, the plastic plates are rectangular, wherein the plastic plates have lengths between 170 cm and 300 cm, preferably between 200 cm and 270 cm, and widths between 70 cm and 260 cm, preferably between 100 cm and 230 cm.
    In an advantageous embodiment, the width of the plastic plates is half the length of the plastic plates. This offers the advantage that two vertically oriented plastic plates can be connected with their broad side on one longitudinal side of a plastic plate. By suitably positioning the openings in the overlapping areas, it is possible to ensure that the plastic panels can be connected to one another both in a parallel orientation along the longitudinal sides or broad sides or in a vertical orientation (longitudinal side to broad side).
    In one embodiment, the fibers of the plastic plates have a length between 10 and 60 mm, preferably between 20 and 50 mm, particularly preferably between 30 and 40 mm.
    In one embodiment, a surface of the plastic plates on point embossing. In general, the plastic plates are laid in such a way that the surface with the point embossings is at the top, i. on the side of the landing surface of the landing field. Dot embossing offers the advantage of increased skid resistance, e.g. for persons who disembark from a landed helicopter or board a helicopter may be advantageous.
    In one embodiment, the fiber content of the plastic plates is between 30 and 60%, preferably between 40 and 50%.
    In one embodiment, the edges of the plastic plates are reinforced with layers and / or tissues of continuous fibers.
    In one embodiment, the plastic plates are reinforced by at least one layer of loops and / or tissues of continuous fibers.
    Preferably, the plastic plates are temperature resistant in a temperature range between -50 ° C and 80 ° C.
    In one embodiment, the connectors have a lower part and a top, wherein the lower part has a receptacle for the upper part and the upper part and the lower part for engaging behind the openings of the, preferably first, overlapping areas are operatively connected by the connector. Typically, the base is first inserted into a pair of overlapping aligned openings and thereafter receives the top into the receptacle provided. Preferably, the receptacle is arranged centrally in the lower part of the connector. After receiving the upper part, the upper part can be operatively connected to the lower part, wherein the active connection usually radial forces are generated on the lower part, which allows engaging behind the openings through the connector, preferably through parts of the lower part of the connector and / or a Grasps behind. By operatively connecting the upper part to the lower part and engaging behind the openings, a positive and / or non-positive engagement of the connector in the openings can be provided. Preferably, the connector is inserted through both openings of a pair of aligned openings and engages behind the opening of the first overlap area, which is typically located below the second overlap area.
    Preferably, the connectors are on the lower side, i. the landing surface opposite side, completed formed. This offers the advantage that water or mud from the ground on which the landing pad rests can not penetrate or only through the connector on the landing surface of the landing pad. The receptacles of the lower parts of the connector can be designed as blind holes, or be sealed by a cover on the bottom.
    In one embodiment, the first and / or the second overlap areas at the openings on subsidence, which can accommodate the connector at least partially. This has the advantage that the landing surface of the landing site can be flattened, which can be advantageous for rolling over the landing surface landing gear. For example, the countersinks can accommodate flanges of the connectors so that they do not protrude, or only slightly, beyond the landing surface or the positive elevations of the plastic panels.
    In one embodiment, the upper part is designed as a bolt, preferably with metal, with a flattened head, and the lower part as a spout, preferably formed with plastic, with a neck and a flange, wherein the neck comprises spring elements, which are formed each engage behind the opening of the, preferably first, overlap region, wherein the bolt can be inserted into the grommet in such a way that the spring elements are positively and / or non-positively connected by gripping means on the inside of the grommet with engaging means of the bolt and the connector into the overlapping openings engages positively and / or non-positively. The inserted into the grommet bolt can serve as a backup, which prevents the spring elements can be pushed away for the solution of the openings.
    In one embodiment, the flange has a countersink, in which the flattened head of the bolt can be accommodated, wherein in the inserted state of the bolt between the head of the bolt and lowering of the flange remains a gap. The lowering is advantageously dimensioned such that the head of the bolt does not or only slightly protrudes beyond the flange, which offers the advantage that the bolt does not interfere with a chassis. The space between the head of the bolt and the countersinking of the flange can be used to release the bolt from the grommet from the insertion side of the connector by gripping the flattened head with a suitable tool and releasing the bolt.
    In one embodiment, the upper part is a screw, and the lower part as a pin comprising an elastic material, preferably rubber, formed with a neck and a flange, wherein the neck in the lower end region has an internal thread, which thus engages with the screw It can be brought that the neck by tightening the screw for engaging behind the opening of the, preferably first, overlapping region forms a bead and the connector engages positively and / or non-positively in the aligned overlapping openings. In general, the screw head rests against the flange and the neck is pressed together by tightening the screw so that the neck forms a bead which engages behind the opening, preferably the first overlap region. This embodiment has the advantage that the connector can be solved in a simple manner by loosening the screw from the openings. The flange may optionally have a countersink into which the screw head can be received. This offers the advantage that the connector on the upper side of the landing site can have a low height, which is advantageous for rolling over the landing pad landing gear.
    In one embodiment, the lower part in the neck on a metallic insert, which includes the internal thread, and the flange has a metallic attachment. The metallic insert and the metallic attachment offer the advantage of increased stability and improved positive and / or non-positive connection when connecting plastic sheets through the connectors. Furthermore, an increased weather resistance is advantageously provided.
    The invention further relates to a deployable fiber reinforced plastic plate for a temporary landing site according to the present description.
    Further, the invention relates to a connector for a temporary landing site according to the present description.
    The invention further relates to a method for producing a deployable fiber-reinforced plastic plate according to the present description, characterized in that the positive and negative elevations are pressed from a pre-preg with a thermoplastic matrix in a mold. Compared to processes in which the fibers or fiber webs are laid into the molds, the plastic plates can be made faster using a prepreg, so that larger quantities can be achieved in the production. Preferably, the prepregs comprise GMT (glass mat reinforced thermoplastics) or LFT (long fiber reinforced thermoplastics). Advantageously, the prepregs can be used from roll, whereby the prepregs can be heated thanks to the thermoplastic properties and then pressed into the desired shape. For the prepregs, cut trovings having a length of between 10 and 60 mm, preferably between 20 and 50 mm, particularly preferably between 30 and 40 mm, are preferably used.
    In one embodiment of the method, the openings are opened during pressing by a hot mandrel. This offers the advantage, in comparison to the drilling of openings, that the fiber-reinforced structure of the plastic plate is not subsequently changed and weakened. The use of a thermoplastic prepreg offers the advantageous possibility of opening the openings of the overlapping areas in the same step as the pressing of the positive and negative elevations, without modifying the fiber-reinforced structure.
    In one embodiment of the method, point embossments are produced during pressing on a surface of the plastic plate, wherein the hot mandrel when opening the openings generates an elevation arranged at the openings, which marks the surface with the point embossings. The hot mandrel may be replaced by a suitable shape e.g. produce a circumferential elevation disposed at the opening, by means of which a user of the plastic plate can detect immediately when laying, which surface has the point embossing and therefore upwards, i. in the direction of the landing area, must be oriented.
    In one embodiment of the method, the edges of the plastic sheet are reinforced with layers and / or woven fabrics of continuous fibers.
    In one embodiment of the method, the plastic plate is reinforced by at least one layer of loops and / or woven fabrics of continuous fibers.

    DESCRIPTION OF EXEMPLARY EMBODIMENTS
    Fig. 1 shows a perspective view of an embodiment of a plastic plate 1. As the plastic plate 1 is stored in Fig. 1, the landing surface is visible. The plastic plate 1 has an inner region with positive elevations 11 and negative elevations 12. In a peripheral outer region, the plastic plate 1 has a first overlap region 13 and a second overlap region 14, which each extend over two adjacent edges of the plastic plate 1. The first overlap region 13 has openings 131 and the second overlap region 14 has openings 141.
    The first overlap region 13 is formed offset from the second overlap region 14 downwards.

The plastic plates 1 a-1 d are each of the same shape as the plastic plate 1 of Fig. 1. The plastic plates 1 a-1 d are laid such that each first overlapping areas of the plates are arranged overlapping below adjacent second overlap areas. For example, a longitudinal edge of the first overlapping region of the plastic plate 1a is arranged below a longitudinal edge of the second overlapping region of the plastic plate 1d. A wide-side edge of the second overlapping area of the plastic plate 1a is arranged correspondingly above a broad-side edge of the first overlapping area of the plastic plate 1b. By connecting other plastic plates (not shown in the figure) of the landing pad 10 is arbitrarily expandable.
    Fig. 3 shows the four laid plastic plates 1a-1d of Fig. 2 in a view from above, so that the overlaps are better visible. Furthermore, it can be seen that overlapping areas are arranged overlapping in such a way that the openings of the overlapping overlapping areas are aligned.
    Fig. 4 shows a perspective view of eight laid plastic plates 1e, 1f, 1g, 1h, 1i, 1j, 1k, 11, which form a landing pad 10 '. It can be seen that the plastic plates 1 i, 1 j, 1 k, 11 have substantially the same arrangement as the plastic plates of Fig. 2 and Fig. 3. Plastic plates 1e, 1f, 1g, 1h with their broad sides are connected in vertical orientation to the longitudinal sides of the plastic plates 1i, 11h, such that the broad-side edges of the first overlapping regions of the plastic plates 1e, 1f, 1g, 1h are below the longitudinal edges of the second overlapping regions the plastic plates 1 i, 11 are arranged. The plastic plates 1e, 1f, 1g, 1h and the plastic plates 1 i, 11 overlap such that the openings of the broad side edges of the first overlapping areas of the plastic plates 1e, 1f, 1g, 1h and the longitudinal edges of the second overlapping areas of the plastic plates 1 i , 11 are cursing. By connecting other plastic panels (not shown in the figure) of the landing pad 10 'can be extended as desired.

The first overlapping region 13 'is formed offset from the second overlap region 14' downwards. The ramp 15 'connects the first overlap region 13' to the second overlap region 14 '. The height at which the first overlap region 13 'is arranged coincides with the negative elevations 12'. The negative elevations 12 'and the first overlapping area 13' are therefore on a substrate on which the plastic plate 1 'is laid on. The second overlapping region 14 'is raised relative to the first overlapping region 13', but lies below the positive elevations 11 '. The second overlap region 14 'is therefore arranged between the negative elevations 12' and the positive elevations 11 '.

In the lower region of the neck 22, an insert 221 made of aluminum is used, which has an internal thread 223. The insert 221 has an opening 222 which forms with the opening 23 of the lower part 2 a receptacle for a screw-shaped upper part, which can engage in the internal thread 223 (not shown in the figure). The neck 22 can be compressed by engaging and tightening a screw in the internal thread 223 in the vertical direction such that a radially facing bead is formed, which can engage behind an opening of a first overlap region.
