Description

The present invention relates to a bar for trellising

arboricultural or viticultural.

  In order to maintain the vegetation, and especially the vines, we install, especially in vineyards, trellises consisting of son stretched on stakes to which are attached vines. These trellises consist of end stakes between which the son are stretched, and intermediate stakes or stakes of rows which serve to support the son by means of bars fixed on the stakes and having holes in which the son pass. There are wooden stakes and metal stakes, and bars adapted to each other. The bars for wooden stakes are made of a formed wire and the bars for metal stakes are either flat metal bars or flat plastic bars.

  The metal bars have the disadvantage of being aggressive for the trellis son. Indeed, under the weight of the vegetation and the wind, the wires rub against the bars, which weakens them and wears them until the break. The plastic strips used mainly for metal stakes have the disadvantage of not having sufficient strength, including weathering.

  The object of the present invention is to remedy these drawbacks by proposing strips for arboricultural or winemaking with metal or wooden stakes, substantially reducing the wear of the trellising wires and having a good service life.

  To this end, the subject of the invention is a bar for arboricultural or viticultural trellising of the type comprising at least one means for retaining a trellis wire and an armature comprising a means for fixing on a support, the at least one means of which retaining a trellis wire is a plastic insert having a hook for retaining a trellis wire, retained in a housing provided for this purpose in the armature.

  Preferably, the frame consists of a rigid wire for example metal, formed to include at least one hook constituting a housing for receiving a plastic insert.

  The hook for receiving a plastic insert is for example u-shaped upright and the plastic insert preferably comprises a hook for retaining a trellis wire and at least one clipping clip in a hook of the frame.

  The fixing means of the trellis bar on a support is for example a loop formed by the wire at mid-length of the armature.

  The frame may also be an elongated rectangular wafer, and the housing for retaining a tether restraining means is a cutout provided on a longitudinal edge of the wafer near an end thereof.

  The fixing means of the bar on a support is for example a 1 o hole provided in the wafer.

  Preferably, the plastic insert comprises a hook for retaining a trellis wire and at least one clipping clip in a cutout provided on the edge of the wafer.

  A bar for arboricultural or winemaking trellises preferably comprises a means for retaining a first trellising wire and a retaining means for a second trellising wire.

  The invention also relates to arboricultural or winemaking techniques of the type comprising vine yarns stretched between two leading stakes and held on row stakes by arboricultural or vineyard trellising bars, the lugs for arboricultural or viticultural trellising being in conformity with one another. to the invention.

  The invention will now be described in more detail but in a nonlimiting manner with reference to the appended figures in which: FIG. 1 represents a bar for arboricultural or wine-growing trellising, according to a first embodiment, FIG. for trellising arboriculture or viticulture, according to a second embodiment, Figure 3 schematically shows an arboricultural trellising element or wine.

  The trellis bar arboricole or viticultural generally indicated by 1 in Figure 1 comprises a frame 2 consisting of a wire, for example a steel wire, possibly galvanized steel, formed by folding so as to have in its middle a loop 3, and at its ends 4, 4 'right U-shaped hooks 5 and 5' whose lateral uprights 6 and 7, 6 '2862840 3 and 7' respectively, are perpendicular to the main body 8 of the armature which makes the connection between the brackets 5 and 5 '. The most extreme lateral amount 7 or 7 ', is a little shorter than the lateral amount 6 or 6' which makes the connection with the main body 8 of the support. Each U-shaped hook, 5 or 5 ', comprises a bottom bar 9, 9' which is the connection between the lateral uprights 6 and 7, or 6 'and 7'. Each end hook U-shaped, 5 or 5 ', supports a plastic insert 10 or 10' comprising on the one hand a hook 11 or 11 'of retaining the trellis wire 12 or 12', and two clamps 13 and 14 or 13 'and 14', intended to be clipped on a lateral upright 6 or 6 'and on the bottom bar 9 or 9' of the U-shaped hook, 5 or 5 ', so as to maintain the insert plastic 10 or 10 'fixed relative to the frame 2 of the bar. These plastic inserts 10 and 10 'have the advantage of being interchangeable. Indeed, they can be implemented by clipping or removed just as easily, which allows to adapt the inserts to the diameter of the son that are supported by bars. In fact, depending on the nature of the vineyards or the season, you may have to change the threads, have thinner threads or larger threads. By adapting the inserts to the diameter of the son, it decreases the causes of friction of the son against the support, and therefore the wear of the son. The interchangeability of the inserts also makes it easy to change those that are prematurely worn.

  The bar which has just been described can be mounted on a trellis as partially shown in FIG. 3. This trellising comprises two head pegs (in the figure only one peg 20 is visible) planted in the floor 21 and held by stays 22 hooked to an anchor 23, driven into the ground. Between these headstocks are stretched son, and especially vine wires 24, which are supported at intervals by stakes of rank 25 on which are fixed bars 26 according to the invention and which are hung son 24 .

  In the first embodiment which has just been described, the stakes of the trellising and in particular the stakes of rank, are wooden stakes and the bars 26 are fixed to the stakes of rank by means of nails, the nails being planted in the loop 3 of the armature of the bar.

  In a second embodiment shown in FIG. 2, the bar marked generally 31, consists of a metal plate 32, for example made of steel, possibly galvanized, having in its central part a hole 33 for fixing to a hook or by a nail on a pole, and at its ends or near its ends 34 and 34 ', lateral cutouts 35 and 35' of rectangular shape, in which are arranged plastic inserts 36 and 36 'each comprising on the one hand a hook 37 or 37 'intended to receive a trellising wire 40 or 40', and secondly clipping clips 38 and 39, or 38 'and 39' intended to clip the plastic insert 36 or 36 'on at least two edges of the cut 35 or 35' of rectangular shape.

  1 o As in the previous embodiment, the inserts 36 and 36 'are interchangeable and therefore can be adapted to the diameter of the trellis son they are intended to receive or can be easily replaced in case of premature wear. In addition, the wafer may have a shape adapted in particular in its central part, so as to be easily attached to poles, and for example on metal poles. In particular, the wafer may comprise stamped or folded parts, intended to cooperate with hooks of metal poles. As in the previous case, this trellis bar can be mounted in an arboricultural or winemaking trellis, being hooked on posts of rank to support son stretched between pegs head.

  Note that in both embodiments, the housing for the plastic inserts are both oriented in the same direction. This arrangement allows the bars to support two son both arranged above the bar so that the inserts are not pulled out of their homes.

  In the two embodiments which have just been described, the plastic inserts may have widths which are adapted so as to have a sufficient bearing surface of the threads on the inserts, in order to distribute the weight of the thread well and vegetation supported by them on the edge of the insert and thus reduce the friction forces.

  The edges of the insert and in particular the edges on which the trellis son support can be rounded so as not to be sharp and be less aggressive for the wire.

  The hook 11, 11 'or 37, 37' for receiving the wire may have a shape, in particular an elongate shape which allows the wire to move slightly inside the insert, allowing the wire to accompany the vegetation when it is displaced by the wind.

  The plastic insert has the advantage of being compatible with plastic threads such as polyamide or polyester, and very fine steel wires.

  The inserts as just described have the advantage of being able to adapt both to the bars whose reinforcement consists of a formed wire, and to the bars whose frame consists of a plate cut.

  Compared to a strip made entirely of plastic material, the strip according to the invention has the advantage of having a metal reinforcement which is resistant to ultraviolet, temperature variations and to all climatic conditions, which is not the case with strips made entirely of plastic that can deteriorate rapidly under the effects of bad weather. In addition, the bar according to the invention is mechanically more resistant.

  Finally, the plastic inserts are small which makes them less fragile than a plastic bar. In addition, they can be changed easily.
