Description
“SUPPORTING POLE FOR VINEYARDS”
DESCRIPTION
TECHNICAL FIELD OF INVENTION
. The present invention is relative to a vineyard supporting pole, in particular
an intermediate pole that is arranged between the two head poles, wherein is stretched
the wire for holding up the growing plants.
PRIOR ART
. With the increasing farm mechanization, vineyards are subjected to more
punishing treatments, carried out in particular with grape harvesting machines. These
machines shake the branches with a certain force, and therefore the plants must be
conveniently supported and trained in their natural growth.
. In short, the layout of a vineyard includes two head poles that are anchored
to the ground with cables or metal braces connected to buried plates of metal or cement;
between the two head poles is stretched a wire, called carrying wire, which supports and
guides the growing grapevines. Each grapevine is held up by a so-called tutor to which
is tied the vine stalk.
. Between the two head poles are also provided intermediate poles,
arranged suitably spaced apart from each other, having the purpose of supporting and
guiding the carrying wire along which will extend the branches and the canopies of the
vines.
. These intermediate poles normally consist of metal section, for example
having a T or a C cross section, to which the carrying wire is fastened with ties made of
pieces of wire. The branches and the canopies of the grapevines can coil around the the
carrying wire and rest on the top end of the intermediate poles.
TECHNICAL PROBLEM TO SOLVE
. The prior art described above refers in particular to a grapevine layout
referred to as free cordon, which has been studied with a view of the mechanized work
carried out on the vineyard.
. The most serious problem in a row of grapevines having this structure is
found at the top ends of the intermediate poles, where the branches of the grapevine tend
in time to develop a phenomenon defined as “embedment”. This phenomenon consists
of a progressive embedding to a certain depth of the end of the pole into the wooden
body of the branch, and is due to the fact that the end surface of the pole has a limited
extent. Moreover, the end of the pole has a rough and irregular finish, as it is a metal
section that does not require a specific finishing machining.
SUMMARY OF THE INVENTION
. The objective of the invention is achieved with a pole for supporting a
vineyard.
. In a particular aspect, the present invention provides Intermediate pole for
supporting a grapevine, arranged between two head poles between which a wire is
stretched in order to hold up the plants, said intermediate pole being made by a metal
section having its lower end driven into the ground, the upper end of the intermediate pole
has a sliding surface for bearing the plants, the sliding surface being furrowed by a groove
within which the wire holding the plant is held, wherein the pole is made by a T-shaped
metal section, the upper end of one of its two wings being curved and forming the sliding
surface for holding the plant.
. The intermediate pole for supporting a grapevine according to paragraph [009]
wherein the wing of the T-shaped metal section, which is provided with the curved upper
end, is further provided with a through hole wherein a fastening member for the supporting
wire is engaged with the pole.
. The intermediate pole for supporting a grapevine according to paragraph [010],
wherein the through hole in which the fastening member of the supporting wire is
engaged, is accomplished at a position spaced lower as regards to the curved end of the
wing of the T-shaped metal section.
. Characteristics and advantages of the invention will become evident from
the description which follows, by way of example without limitations, with reference to the
enclosed drawings, wherein:
- Fig. 1 illustrates schematically a row of grapevines in a vineyard;
- Fig. 2 illustrates, in a perspective view, an intermediate vineyard support pole of Fig.
1, according to the prior art;
- Fig. 3 illustrates, in a perspective view, an intermediate vineyard support pole of Fig.
1, according to the present invention;
- Fig. 4 illustrates, in partial cross section, a detail of the pole of Fig. 3, and
- Fig. 5 illustrates, I a perspective view, the pole of Fig. 3, on which is supported a
part of the plant.
DETAILED DESCRIPTION OF THE INVENTION
. Fig. 1 illustrates schematically a row of grapevines in a vineyard.
. Substantially, the vine row consists of two head poles 10, that are
anchored to the ground by means of cables, or metal braces, 12 connected to buried
plates 14 made of metal or cement. Between the two head poles 10 is stretched a wire
16, referred to as carrying wire. The carrying wire 16 must hold up and guide the plants
18 during their growth. Each grapevine is supported by a tutor 20 to which the stalk of the
vine.
. Between the two head poles 10 are also provided a plurality of
intermediate poles 22 (only one is shown in the figure), arranged suitably spaced apart,
whose purpose is to hold up and guide the carrying wire 16, along which are trained the
branches and the canopies of the grapevines.
. The intermediate poles 22 are normally made with metal sections, for
example with a T or C cross section, which are driven into the ground and to which the
carrying wire 16 is normally fastened with ties consisting of pieces of wire.
. As shown in Fig. 1, the branches of the grapevines can entwine around
the carrying wire, and eventually they grow until they rest on the top end of the
intermediate poles 22.
. Fig. 2 illustrates, in a perspective view, an intermediate pole 22 for
supporting the vineyard of Fig. 1, according to the prior art.
. The intermediate pole 22, in the specific example, is a metal section with
a T-shaped cross section, in which the wing 24 orthogonal in the direction of extension of
the carrying wire 16 has its upper end provided with a notch 26 to hold and guide the
carrying wire 16. Further, the wing 24 of the intermediate pole 22 is provided with a
through hole 28 which holds the fastening member used to tie the carrying wire 16 to the
intermediate pole 22. The through hole 28 is provided in a suitable position below the
notch 26.
. As already mentioned, the drawback of this type of pole lies in the fact that
the grapevine on a traditional T-shaped pole tends to “embed”, that is, incorporate in its
stalk the upper metal part of the support.
. This situation occurs due to the following reasons:
- The stable part (about 20 years) of the grapevine (horizontal stalk) is tied very firmly,
being wound and entwined around the carrying wire, an important requirement to
mechanize the various processes, like pruning, harvesting, etc.
- The weight of the whole: stalk-vegetation-fruit (grapes).
- Mechanical actions such as shaking, vibrations, etc., carried out during the various
processes.
- Very small cross section of the upper part of the intermediate support pole, which
supports the whole at that height above the ground.
. Fig. 3 illustrates, in perspective, an intermediate pole 22, according to the
invention; numerical references corresponding to the ones of the prior-art pole are
maintained in the description of the pole of the present invention.
. In this case too, the pole 22 consists of a T-shaped metal section, but in
this case the wing 24, which is orthogonal to the direction of extension of the carrying
wire, has a curved upper end 30. In this manner, the upper end 30 presents to the growing
branches of the vine a substantially smooth support surface that is much wider, thus
avoiding the risk of the support becoming embedded in the wooden part of the plant.
. To guarantee in any case the guide of the carrying wire 16, the surface of
the upper end 30 of the pole 22 is still provided with a notch 32 aligned with the direction
of extension of the carrying wire.
. The wing 24 of the T-shaped section is also provided with a through hole
28 for engaging the member 34 for fastening the carrying wire to the intermediate pole
. Fig. 4 illustrates, in partial cross section, a detail of the intermediate pole
22 viewed in the direction of extension of the carrying wire 16.
. As can be seen, thanks to its curvature, the upper end of the wing 24 is
perfectly adapted to guide the carrying wire 16 by means of the notch 32, and also
provides a surface that is effectively smooth for supporting the branches 18 of the
grapevine.
. Fig. 5 illustrates in a perspective view the pole of Fig. 3, on which is
supported a part of the grapevine 18. The innovative solution thus appears as particularly
simple and effective for solving the technical problem indicated above.
