Description

Parachute consisting of detachably connected single webs

Description

The invention relates to a parachute consisting of a plurality of individual, separate textile single webs, wherein at least two each more parallel to each other extending single webs

comprehensive groups of individual tracks are aligned in a crossing arrangement and together form the parachute of the parachute parachute and wherein each of the intersecting single tracks of the individual groups are connected to each other and attached to the outer ends of the individual tracks carrying lines for holding a to be attached to the parachute load ,

A parachute having the aforementioned features is described in US 6 959 897 B2. To complete the complicated sewing one usually

To avoid parachute cap with apex and circumferential base, the known parachute consists of a plurality of single tracks, which together form the parachute cap and at the free outer ends of the carrying lines are fixed for holding a hanging on the parachute load. There are provided two each consisting of several mutually parallel single webs existing groups of single tracks, wherein the one group of single tracks is aligned at right angles to the course of the individual tracks of the other group and the two groups with their

Single tracks are laid on top of each other. The individual paths of the two groups, which in each case cross each other, are in their intersection

CONFIRMATION COPY sewn together tightly. Since the individual tracks are arranged in the two groups each with a distance to each other, resulting in the

Intersection areas of the single-web flow-through openings, which serve to protect the parachute from excessive loading, in particular at the time of the opening of the parachute.

With the known parachute still has the disadvantage that the sewing of the crosswise extending single sheets requires the provision of appropriate sewing machines; also is the handling

especially large-scale parachute caps during the sewing difficult.

The invention is therefore based on the object to improve a parachute with the generic features so that its manufacture and handling is simplified.

The solution to this problem arises including advantageous

Embodiments and developments of the invention from the content of the claims, which are nachgestellt this description.

The basic idea of the invention is that in order to connect the intersecting individual webs with one another in their overlapping areas on the respective mutually facing surfaces of the individual webs, there is at least one loop for receiving the loops of the two webs

Single lanes releasably interconnecting connecting elements is attached. Thus, the invention is characterized by the solution principle that the individual tracks of a predetermined parachute size can each be formed in an identical manner with the loops arranged thereon. During assembly of the parachute, the loops which are respectively attached to the individual webs come to one another in such a position that, in each case, suitable connecting elements are assigned by the correspondingly assigned fasteners Threaded loops and thus the individual tracks can be detachably connected together in their overlapping areas.

The invention has the advantage that only the production of single webs is required. It is not necessary to sew the webs together over the cross. A further advantage is that the connection of the

Single tracks without sewing takes place and is made only by attaching the connecting elements to the appropriately aligned loops of the individual tracks. Thus, since the connection of the individual tracks with each other is solvable, individual tracks of the parachute can be replaced without much effort, so that the parachutes can be easily kept ready for use. Also, the recovery of such parachutes in difficult terrain, for example, in a forest, easier, since possibly the parachute can be disassembled in place by simply loosening the fasteners in its individual tracks, which can then recover easier. Then the parachute can be reinstalled and replaced if necessary. In the case of damage to a parachute other parachutes of the same size and design can be used as a spare part dispenser because the individual tracks each have an identical design.

According to a preferred embodiment of the invention it can be provided that at least one extending over the length of the single web reinforcing tape as a carrier of the

Loops is applied and connected to the outer ends of the reinforcing tape, the carrying lines of the parachute. By arranging de reinforcing bands on the individual tracks a secure attachment of the loops is ensured on the individual tracks, and

On the other hand, the reinforcing tapes are used to hold a load to be towed by the parachute via the load-bearing lines, so that the power flow from the carrying lines takes place exclusively via the reinforcing bands of the individual webs. The reinforcing tapes can work with the fabric the individual tracks be connected by means of continuous seams. Alternatively, however, a point-by-point connection of reinforcing tapes and single webs may be expedient in order to take into account a different expansion behavior of the materials used.

Here, according to a first embodiment of the invention

be provided that in each case a running in the middle j eder single web reinforcing band is provided. This makes it possible for that

Embodiment which in the overlapping areas at the two

Single tracks each arranged loops are arranged in the crossing points of the reinforcing bands of the intersecting single tracks.

Thus, if two intersecting individual webs lie on top of each other, the resulting loop arrangement ensures that in each case a loop arranged on the one individual web on its underside facing the intersecting single web intersects with the other at the other

Single track on which the single track facing top correspondingly arranged single loop comes into contact, so that through the two individual loops to their mutual connection, a connecting element is hindurchfädelbar.

The invention is initially based on the fact that the individual tracks of the first group are placed on the individual tracks of the second group, so that the loops at the first, top group of

Single tracks belonging to single tracks are arranged at the belonging to the second group single tracks facing bottom, while the loops are arranged in the second underlying group of individual tracks associated individual tracks at the top.

Alternatively it can be provided that in each case a reinforcing strip is arranged at the outer edge regions of the individual webs, wherein the ends of the individual webs with the reinforcing tapes mounted thereon narrow outwards in a triangular manner onto a connection for the wearing lines. These Constriction can be realized by a corresponding cutting of the individual webs, but alternatively also via a corresponding folding of the ends of the individual webs, so that a cutting of the webs is avoided. As part of a folding, the loops for the connection of the supporting lines can be formed.

With such an arrangement of the reinforcing bands, overlapping areas with four result at the individual webs crossing each other

Corner points, where two are each in the peripheral areas of

Cross single-web reinforcing ribbons. Accordingly, in such an embodiment of the invention, it is provided that in each of the four corner points of an overlapping region of two intersecting individual webs formed by each of the crossing reinforcing tapes, a loop is attached to each individual web and in each case one

Lanyard is threaded through the two existing in each corner point belonging to different individual tracks loops. Thus, a fastening of the intersecting individual webs at all four corners of the overlapping region by connecting in each case two loops by means of a connecting element.

To reinforce the connection of the individual webs at the crossing points of each two reinforcing tapes can be provided that the loop connections provided there is formed by a pair of loops attached to each j individual track. Specifically, it can be provided for this purpose that in each of the four corner points of an overlapping region of two intersecting individual webs formed by the respectively crossing reinforcing tapes, a loop pair is attached to each individual web and a connecting element for connecting the individual webs in each corner is in each case four Loops is guided, of which two loops are attached to the one single track and two loops on the other crossing this single crossing, wherein it may be provided that the j eweils a loop pair forming, attached to a single track loops such are arranged at a distance from each other, that the loop pair forming loops of a single web the the reinforcing band with the attached loops carrying edge region of the crossing

Include single track between themselves. Accordingly, the consequence is that the loops of a pair of loops are also provided with a pair of loops edge region of a crossing single track between them

enclose, allowing the four loops of the two to be joined

Single lanes ideally lying on a circle.

The strength of the parachute can be further improved by the fact that it is provided according to a preferred embodiment of the invention that the single lanes of a group of single lanes with the intersecting single lanes of the other group form a mesh such that the individual lanes alternately in their course above a crossing single track and below the next crossing single track and so forth are guided; Because of this mutually changing course of upper and lower single track, it is necessary in this embodiment, that over the extension of each

Single track are arranged at this arranged loops alternately on the top of the single track and on the underside.

With regard to the attachment of the individual loops on the individual tracks of the parachute can be provided according to a first embodiment of the invention that the loops individually on the material of

Reinforcement tapes are sewn on.

According to a preferred embodiment of the invention, the connecting elements provided for connecting the loops consist of detachable textile shackles, which are offered for example by the company Rosenberger Tauwerk GmbH under the name "Liros-XTR soft shackle". Alternatively, the connecting elements can also consist of detachable metallic shackles.

According to one embodiment of the invention, it may also be sufficient if the connecting elements of separable textile

Rope sections exist, wherein the ends of the cable sections can be knotted together or interconnected by means of a mutual splice. In such cases, the separation of the

Single lanes of each other by separating the connecting elements serving cable sections happen, with new ropes are to be used when reassembling the single lanes.

Fig. 8 shows the detail "X" of Figure 7 in an enlarged detail view.

As first shown in Figure 1, the parachute has a

Parachute 10 on, which consists of a plurality of separately manufactured and assembled single sheets 1 1. At the ends 12 of the individual tracks 1 1 carrying lines 13 are attached to which a parachute to be dropped, but not shown load is supported.

As is apparent from Figure 2, the parachute 10 is in the

illustrated embodiment of two, each consisting of four single tracks groups 30 and 3 1 of individual tracks 1 1, wherein the two groups 30 and 3 1 are arranged with their individual tracks 1 1 at right angles to each other. The single lanes 1 1 of a group 30 form with the intersecting single lanes 1 1 of the other group 31 a mesh such that the individual lanes 1 1 in their course each alternately above a crossing single lane 1 1 and below the next single crossing single lane 1 and so forth on the basis of the individual tracks 1 1 assembled parachute 10 are performed. Since the individual webs 1 1 are each arranged at a distance 15 from each other within the two groups 30 and 3 1, arise between the intersecting single webs 1 1 of the two groups 30 and 3 1 each through-openings 16 for the air bearing the parachute. The intersecting individual webs 1 1 thereby form an overlap region 1 7, each with defined vertices 1 8, wherein the overlap region 17 to Attaching the intersecting single sheets 11 is used together, as described below.

In FIG. 3, a single lane IIa of the first group 30 of individual lanes according to FIG. 2 is shown completely, wherein this single individual lane IIa is crossed by a plurality of individual lanes IIb, 11c, 11d, 11e of the second group 31 of individual lanes, and in a corresponding manner FIG. 2

braid-like arrangement. Here, the single track IIa engages under the first intersecting single lane IIb and overlaps the following crossing

Single track 11c and so on. In addition, adjacent individual tracks IIal and 1 La2 of the first group 30 are indicated only with their parallel edge regions to make it clear that within the first group 30, the single lanes 11 a and llal and 11 a2 alternately the first intersecting single lane IIb of the second Group under attack respectively

spread.

As can further be seen from FIG. 3, the connection of FIG

Single webs 11 in the overlapping region 17 are attached to each other at the outer edges of a single web IIa shown in FIG. 3, in each case one reinforcing web 20 extending over the length of the single web IIa. The ends of the single track IIa with the attached

Reinforcement tapes 20 narrow each outwardly triangular on a connection 24 for the supporting lines 13. Thus, it is ensured that the power flow from the supporting lines 13 ago exclusively on the

Reinforcement bands of the single track IIa takes place. The individual tracks 11 in the parachute according to the invention are so far formed in the same way.

Insofar as shown in FIG. 3, the single track I a shown in full is the other single lanes IIb or 11c or lldbzw. If all crosses braid, overlap regions 17 with associated corner points 18 at the respective intersecting single webs 11, wherein in the area of

Corner points 18 each loop connections for releasable connection of Single tracks 1 1 are attached together. The positions of the loops provided in FIG. 3 are initially indicated in each case by the points 19.

FIG. 4 shows an enlarged illustration of a continuous reinforcing band 20 attached to the single web 11a with the loops 2 1 sewn thereto individually. Since FIGS. 3 and 4 each show the mesh-like

Connection of the individual webs 1 1 show each other, the recognizable in Figure 4 left loop pair 25 for connecting the single web I I a with an individual track lying above 1 1 d set, and therefore the loops 2 1 in the illustration of Figure 4 on the top of

Reinforced tape 20 sewn. Since the individual web II a in its further course according to FIG. 3 subsequently overlaps the next single crossing 1 1 e above this single web 11 1, the loops 21 of the right loop pair 25 in FIG. 4 are from below to the individual web II a or their reinforcing web 20 sewn, wherein the loops 21 are placed on the fabric of the single web II a and the seams pierce the fabric web.

The connection of two individual tracks I I a and 1 l d (corresponding to Figure 3) is for a crossing point of the edge mounted

Reinforcing bands 20 shown in Figure 5. The single lane I I a is crossed over by a single track 1 1 d arranged above, wherein in each case a loop pair 25 with two loops 21 on the

Reinforcement tape 20 of the single web 1 la is mounted, which is arranged on the single-crossing of the intersecting single web 1 1 d surface of the single web II. Accordingly, in the crossing single web 1 1 d, the reinforcing tape 20 with attached loops 21 on the single web II a facing surface, that is, the bottom of the single web 1 ld applied. The loops 21 of the loops pairs 25, which are in each case arranged on a reinforcing strip 20 of a single web IIa or L1, are arranged at such a distance from one another that the loops 21 enclose the outer edge region of the other single web 11 extending crosswise therebetween, so that ideally the four loops 21 of the two individual webs 1 la and 1 ld lie on a circle and are thus jointly grasped and held together by a connecting element 22 threaded through the four loops 2 1. Corresponding loop connections are in each case provided in all vertices 1 8 of the overlapping areas 1 7 of intersecting individual tracks 1 1.

As described at the beginning, the mesh-like arrangement of the individual webs 1 1 described for the preceding embodiment is not absolutely necessary. It is quite sufficient if the one group 30 forming

Single lanes are in each case placed on the other group 3 1 forming single lanes. In such a case, the loops 21 mounted on the individual webs in each case have a rectilinear orientation in each case.

In the exemplary embodiment illustrated in FIG. 6, but otherwise corresponding to FIG. 3, only one reinforcing band 20 is arranged on each individual web 1 1 concerned, which in each case is arranged in the middle of each individual web 11. As already described with reference to FIGS. 3 and 4, the single web IIa shown completely in FIG. 6 crosses the further individual webs IIb or 11c or 11d, respectively, the arrangement of the individual webs crossing each other in contrast to FIG is. Rather, the single lane II a and further parallel to it, but not shown in Figure 6 single lanes are in a plane above the individual lanes II b to ll e crossed by them. Insofar as the intersecting individual webs again form overlapping areas 1 7, the lines carrying the loops 2 1 lie thereon. Strength bands 20 formed crossing points 19 in the middle j edes overlap area.

According to another exemplary embodiment illustrated in FIGS. 7 and 8, it is quite sufficient if, according to the embodiment shown in FIGS. 3 and 4, only one loop 21 instead of one loop pair 25 shown in FIG. 4 is used to connect the single web II a to an individual web lying above 1 1 d is provided. In this case, the left in the illustration of Figure 7 loop 21 is sewn onto the top of the reinforcing strip 20. Since the single web II a in its further course according to FIG. 7 subsequently overlaps the next single crossing 1 1 e above this single web 11 1, the associated loop 21 in the right-hand representation of FIG. 8 is from below to the single web II a or its reinforcing band 20 sewn on. In a similar manner, as shown in Figure 5, which are sewn to the individual web II a or their reinforcing tape 20 loops 21 with the corresponding only individually sewn loops of the reinforcing bands of the intersecting single webs II b bi s 1 1 e by means of a two loops threaded connector detected and held together.
