DE29503115U1 - Ground anchors or screw pegs for fastening tension lines, tent loops, poles and tubular elements to the ground - Google Patents

Description

X . S'fceand the

Tents and guy ropes are usually secured with pegs (made of metal or plastic) that are hammered into the ground with a hammer. Alternatively, there are ground screws that are screwed into the ground. Parasols, posts and poles are usually pointed at the bottom and are usually hammered into the ground with a hammer or pressed in by hand. There are stands for parasols that are filled with water or sand to prevent the parasol from falling over.

II - Criticism of the European Union's financial situation. Deficiencies of the previously known versions of Heringen:

1. The tent pegs currently in use tend to come loose from the ground easily (especially when subjected to stress such as the tent walls flapping in the wind or the weight of rain or snow on the tent roof).

2. If pegs hit solid materials (e.g. stones) when being driven into the ground, they bend (in the case of metal pegs), break off (in the case of plastic pegs) and/or tip to the side and become loose in the upper area.

3. Pegs are often difficult to hammer into the ground and/or difficult to pull out again in hard soil.

4. To ensure a firm hold on soft ground, extremely long pegs are required.

5. Since the arms quickly become weak when hammering in pegs, you hit them with a hammer (or similar)

not always just the herring, but also, with increasing probability, your own hand with which you hold the herring.

6. When hammering in the pegs, guy ropes and tent loops are often torn or knocked off. Tent walls can also be damaged.

Deficiencies of the previously known designs of earth screws:

1. Since conventional ground screws often have a conical or wedge-shaped form, they can jam when they encounter resistance.

2. When screwing in the earth screws offered so far, a very high rotational resistance often has to be overcome.

3. The earth screws or ground anchors, which are usually very complex in design, are usually too expensive for private customers and are therefore mainly used in the construction industry (e.g. foundation engineering).

Deficiencies of the previously known designs of parasol stands:

1. The parasols, posts and poles that are pointed at the bottom easily come loose from the ground and fall over, especially on sandy ground. On harder ground, they cannot be inserted deep enough into the ground in the first place.

2. Parasol bases that are filled with water or sand must be very large, as (due to the strong leverage) a high weight is necessary to prevent the parasols from tipping over in strong winds.

XXX . Tasks & Objectives

The invention is based on the following objects:

1. The screw peg (ground anchor) is intended to provide a possibility for securing tents, which optimally ensures that guy ropes and tent loops are firmly anchored in the ground, regardless of its condition.

2. A screw peg should be offered that allows effortless screwing into different types of soil (e.g. sandy, stony, swampy, mixed).

3. Since there are limits on the loading of passenger cars and caravans or trailers during holiday trips, unnecessary weight should be avoided.

4. The longer lifespan of the screw pegs and the protection of the tent walls and the fastening loops should avoid the additional costs incurred with conventional pegs.

5. It should be prevented that tent loops or guy ropes come loose from the screw peg.

6. A way of attaching parasols and other tube- or pole-shaped objects (such as tent poles or flagpoles for golfers) to the ground should be created that can be easily screwed into different types of soil and also has a high holding force.

The objects are achieved according to the invention in that

1. the screw peg 1 or 7 penetrates easily into the ground and anchors itself there thanks to its corkscrew-like windings 2 and cylindrical outer shape.

2. the screw peg can be easily screwed into the ground and unscrewed again due to its shape and its different handling options (e.g. screwing in using a cordless drill or alternatively using a caravan crank). When using a cordless drill, a screw coupling specially made for the screw pegs can be used, which also allows the screw pegs to be screwed in by hand.

3. Because they are made from plastic or glass-fibre reinforced plastic, the screw pegs are particularly stable and yet very light.

4. The use of plastic enables a long durability (e.g. rust-proof, does not bend). Since guy ropes, fastening loops and walls of the tents are no longer subjected to such extreme stress as when hammering in pegs, their service life is also increased.

5. the shaft 4 is equipped with all-round retaining rings (=bulges) 5 to prevent the tensioning lines and hanging loops from slipping. S-shaped hanging clips 6 can also be attached to these anti-slip devices, which are distributed at equal intervals along the shaft of the screw peg, the inner diameter of which corresponds to the outer diameter of the shaft and which are angled at around 45° in the middle.

6. the hexagonal screw head is replaced by a hole 8 in the shaft 4 to accommodate various pipe elements (see claims 9-11). This ensures that the invention can also be used to attach sunshades and poles. The ground anchor is then larger (according to this task) and equipped with pivoting lever arms 9 for screwing into the ground.

The two drawings (Figures 1 and 2) show two different embodiments of the invention.

Figure 1 shows a ground anchor (1) which is particularly suitable for securing guy ropes and tent loops to the ground. In this embodiment, the corkscrew-shaped thread (2) is connected to a hexagon head (3) by a shaft (4) which has circumferential retaining rings (5).

Figure 2 shows a ground anchor (7) which is primarily used to connect tubular or rod-shaped parts (such as those attached to sunshades) to the ground. Here, the shaft (4) is open at the top and hollow inside (8) (shown as a section in the figure) and has pivoting lever arms (9) with clamping cams (10).

From the universally applicable standard versions, special versions can also be developed for different types of soil (e.g. screw pegs with a larger diameter and wider coils especially for sandy ground).
