DE2933550A1 - Vineyard wire tensioning post - has suspension slots at different heights undercut at top and bottom - Google Patents

Abstract

The post allows tension wires to be secured at various heights, being partic. for holding vine stems upright. On one or both sides it has a large number of suspension slots (2) for the wires (3), undercut at the top and bottom, and inclined to its lengthwise axis. The slots can be of curved or angular section, and the post can be of hard plastics foam, with a non-round and preferably oval cross-section, the slots being at the end where diameter is greatest. Between successive slots recesses can be formed in the post, to save material.

"Posts, especially for grapevines"

The invention relates to a post for height adjustment Fastening of tension wires, especially for pulling up grapevines.

To pull up the vines, it has been customary to attach tensioning wires to mostly wooden posts that are connected to the Growth of the grapevines are shifted higher and higher. In addition to the mostly used fastening of the tension wires by means of Staples, which make loosening and relocating the tension wires extremely cumbersome, are also fastening arrangements with clamps has been proposed, but the height adjustment because of the necessary actuation of the clamping devices make the tension wires also very labor-intensive.

The invention is therefore based on the object of designing such a post with fastening devices for the tension wires so that that it can be produced easily and inexpensively and in particular a very simple height adjustment of the Tension wires permitted.

To solve this problem, the above-mentioned post is used in the case of a post Kind according to the invention provided that it is undercut at least on one side with a plurality of spaced apart top and bottom and is provided with hanging slots inclined at least in sections to the longitudinal axis.

The provision of such inclined to the longitudinal axis of the post or but provided with a curvature or angled undercut Longitudinal slots allow the tension wire, derjfeu, to be hooked in easily For this purpose, the hanging section is slightly inclined or bent by hand so that it is inserted into the slot leaves, after which he resumes the usual horizontal position due to his tension, so that he -independent of how it is loaded and which position it occupies behind the slot can no longer get out of the suspension slot on its own can. This simple attachment makes the height adjustment of a tension wire extremely easy. While a person unhooks the tension wires from the suspension slots a person walking behind a few posts moves the tension wires without difficulty in a world-top mounting bracket hook again. With this simple adjustment

foam, and not just in terms of rotability such rigid plastic foam materials from Vor; | part, but also the possibility of molding a large number of suspension slots with the manufacture of the post offers, so that the introduction of the slots means practically no complication of the post production at all.

In the event that you want to drive the posts into the ground with a ram or sledgehammer, what in the case of rigid foamed plastics, which can lead to difficulties because of their excessive brittleness, in Further development of the invention can also be provided that a stiffening insert is embedded in the post, which consists of Plastic, wood or metal can be made.

On the one hand, to ensure a high load-bearing capacity of the posts and on the other hand not too much plastic material is required, can be provided in a further development of the invention be that the post has a non-circular, preferably approximately oval cross-section and the suspension slots at the end of the largest diameter are arranged.

It is also within the scope of the invention, at least in the area between successive suspension slots, in order to save material To provide serving recesses, for example in such a way that the post in these sections is cross-shaped Has cross section.

To pull up the vines, the individual rows of vines are used a plurality of spaced-apart posts 1 are buried or driven into the ground, in the manner shown in FIG Embodiment are provided on one side with a plurality of spaced mounting slots 2. These hanging slots 2 are inclined to the longitudinal axis of the post and undercut at the top and bottom. In this way, an in the suspension slots 2 of the post 1 suspended tension wire 3, which should have a substantially horizontal position and thus runs perpendicular to the longitudinal axis of the post 1, after hanging, which of course a certain bending of the Suspending section requires no longer step out of the slot 2, but it remains in the lower undercut or the upper undercut 5 caught. The post is made of rigid plastic foam, with the undercut according to the invention Attachment slots 2 during the manufacture of the post I

molded in in one operation by means of corresponding molded inserts have been. The post 1 shown in Figures 1 to 3 has an approximately oval cross-section, the Hanging slots are arranged at the ends of the largest diameter. This means that with relatively little material consumption (Total cross-sectional area) ensures high post strength.

In the embodiment shown in FIGS the post 1 is also in the area between one above the other Hanging slots provided with recesses 6 in such a way that it is essentially a Has cruciform cross-section. This allows even more plastic material to be saved in the manufacture of the post, without having to accept any significant impairment of the post stability.

In Figure 6 you can see a curved design of the I slot 2. Obviously, such a curvature, or an angular design of the longitudinal slot is equally suitable to prevent the tension wire from automatically stepping out, while the hanging by corresponding bending of hand poses no \ difficulties in lodging the tension wire.

ί In the embodiment according to Figures 7 and 8 can be seen a wooden core 7, which is covered on all sides with a plastic coating

Mige projections 9 with molded, by inclined or arched Suspension slots 2 are interrupted. During the post in its upper, the side projections 9 with the Einhä'nschlitzen 2 bearing section has a rectangular cross section, the lower section is circular in cross section and provided with a thread 10 for screwing into the ground. This screwing in can thereby be accomplished particularly easily that the post has a transverse recess 11 through which one serves as a handle when screwing Rod can be inserted.
