Description

"Post for holding wires, mesh or similar, especially for use in agriculture"

The invention relates to a post for holding wires, wire mesh or the like, in particular for use in agriculture as a garden and/or pasture fence, as a vineyard stake, as a espalier fruit post or the like, made of a plastic tube open at the top with an end cap arranged on it.

Posts of this type made of plastic pipes are well known. They can have molded-on webs with recesses for hanging tension wires or similar. These pipes are driven into the ground. In order to prevent water, especially rainwater, from penetrating these pipes from above, it is well known to close them at their free front end with a plastic end cap that can be attached around the pipe. In practice, however, it has been shown that these plastic end caps can often be lost; in particular, they are not suitable for combine harvesters, as these machines loosen or knock the caps off.

However, if the post is open at the top, it can fill up with water at least in some areas, which can lead to significant frost damage. It can even lead to complete collapse.

Permanent closure of the pile on one side is possible. This closure cannot be lost due to the permanent connection to the pipe, so that a complete pile closure is guaranteed for the life of the pile. It is advantageous that the end cap is made of a similar material to the plastic pipe.

According to a particularly preferred embodiment of the invention, the connection is designed as a rental connection. This type of connection is particularly simple, since after placing the closure cap on the plastic pipe, only at least two rivets have to be driven into the plastic pipe and the areas of the cap that engage in the pipe.

It can also be provided that the connection is designed as a tack connection. The areas of the cap that protrude into the pipe are also permanently connected to the pipe.

It can also be useful if the connection is made as a welded or glued connection. Of course, other permanent

connections should be provided.

In order to further improve the tightness of the end cap, it can also be provided that a seal is arranged between the areas of the cap and the pipe.

Finally, the outer surface of the cap should be flush with the outside of the pipe. This design ensures that the end cap is flush with the pipe and thus does not provide a surface for a harvesting machine or similar to attack, which could cause the cap to be forcibly torn off.

The invention is explained in more detail below using the drawing as an example. The only figure shows a perspective, partially sectioned view of a head region of a pile according to the invention.

The post 1 shown in the figure consists of a plastic tube with lateral retaining webs 2 or 3 for tension wires or the like, which are not shown in detail in the drawing. For this purpose, holes 4 or, as shown in the web 3, hook recesses 5 can be provided in the webs 2. Only the head area of the post 1 is shown in the figure. This head area is marked with the curved bracket 6.

A cap 7 is placed on the top of the open head area 6 of the pile 1. The cap 7 has

7 inwardly projecting areas Qr which engage in the pipe 1. Preferably, an annular seal IC? is inserted between these areas 8 and the pipe wall 9 for sealing. The areas 8 are firmly connected to the pipe wall 9 by means of a permanent connection, a rivet connection 11 being shown in the drawing. Of course, this connection could also be designed as a tacked, welded or glued connection or the like.

The outer surface 12 of the end cap 7 is designed to be flush with the outer surface 13 of the tube 1, so that no edge is formed in the connection area which a harvesting machine or the like could attack, which could then lead to the closure cap 7 being forcibly detached from the tube 1.

The assembly of the pile is particularly simple. After driving the pile 1 into the ground, the end cap 7 with the seal 10 only has to be placed on the open end of the pile 1. A permanent connection is then made between the areas 8 and the pipe wall 9 by riveting, stapling, gluing, welding or similar, so that a permanent, watertight seal is created for the pile 1*

Of course, the invention is not limited to the embodiment shown in the drawing.

Further embodiments of the invention are possible without departing from the basic idea. For example, the end cap 7 can also be cup-shaped, whereby this embodiment is particularly suitable for staplers.
