Description

"Pro-Pack" tarpaulin for ram-air parachutes with sun protector.

Various packing tarpaulins are known from the state of the art. For example, various commercially available rectangular tarpaulins are used as packing tarpaulins in the parachuting sector. The disadvantage of such tarpaulins is that they are made of thick plastic material and thus have a high transport weight and are difficult to handle during transport, or of light, sensitive and thus short-lived plastic materials. Furthermore, all known packing tarpaulins do not have the option of using the packing tarpaulin as a bag during transport. They also lack other features to meet the needs of parachutists. In some cases, packing mats are used on which only the harness can be placed. These tarpaulins have the disadvantage that the parachute lines and the material of the parachute canopy are laid directly on the ground, which leads to soiling and damage to the line and canopy material. None of these tarpaulins has an integrated protector against the UV rays of sunlight, which at the same time offers the option of being folded up and used as a transport bag with the zipper closed. Tarpaulins that have the features according to the invention are not known from the state of the art.

The invention described in claim 1 is based on the problem
that during the 15 to 20 minute packing process, the parachute harness is exposed to sunlight (UV radiation) without protection. Due to the fact that parachute harnesses are made of UV-sensitive material and the fact that parachute jumps are usually only carried out when the sky is clear, it is necessary to integrate a protective device into packing tarpaulins in such a way that it is user-friendly and can ideally be used for other functions. In addition, it is a requirement of the invention

Protection claim 1, to design it in terms of its dimensions in such a way that it is adapted to the "Pro-Pack" packing method that has become widespread in recent years.

This problem is solved with the features listed in claim 1.

The invention ensures that ramps packed according to the "Pro-Pack" method can be laid out completely on the packing tarpaulin and that the harness, the sensitive lines and the sensitive canopy material are protected from contact with the ground and that a closed flap in the storage area of the harness acts as a sun protector to protect the harness against harmful UV radiation. Furthermore, this flap is provided with a circumferential zipper, which gives the packer the option of opening the opened flap to the left, right or downwards and using it as knee protection when packing. This flap can be used as a lockable surface when transporting the tarpaulin, into which the entire tarpaulin is packed.

An embodiment of the invention is explained with reference to Figures 1 to 2. They show:

Fig. 1 the tarpaulin opened to accommodate the unfolded parachute Fig. 2 the three opening options of the sun protector.

The area marked (1) in Figure 1 includes the entire storage area of the unfolded parachute unit, with the lower storage area for the harness marked (1.1) and the upper storage area for the parachute canopy and lines marked (1.2). The sun protector marked (2) is connected to the packing tarpaulin using a zip fastener (3). The entire packing tarpaulin is anchored to the ground using ground anchoring straps (5) and standard pegs, which on the one hand prevents it from being blown away by the wind and on the other hand offers the possibility of anchoring the harness firmly to the ground using the retaining straps (4) so that it can be packed under tension. This is the only way to prevent the parachute lines from getting tangled in the air when the parachute is opened.

The carrying strap (6) allows the folded tarpaulin to be carried
(transport situation) like a carrying bag, with a variety of other
Skydiving related items can be transported.
The small parts pocket (7) with zipper allows the storage of small
objects.

Figure 2 shows the sun protector unfolded: 1 x to the right and with dashed lines 1 x to the left and 1 x down.

Claims (1)

A packing tarpaulin for surface parachutes, characterized in that it consists of a piece of rectangular natural or synthetic fiber fabric ( 1 ) with an upper side and a lower side, which has a first and a second end, to which first end a second piece of rectangular natural or synthetic fiber fabric ( 2 ) is permanently attached by a 270° circumferential zipper ( 3 ) and corresponds in its transverse side length to that of the first piece of rectangular natural or synthetic fiber fabric ( 1 ), to which second end a trapezoidal natural or synthetic fiber fabric ( 1.2 ) is permanently attached, the narrow transverse side length of which corresponds to the transverse side of ( 1 ).
