Definitions
- the invention relates to an electric fence, in which the electrically conductive structure is of a new type, capable of optimizing the characteristics and properties of these fences.
- Electric fences are widely used today, in particular given their ease of installation, and also their ability to keep animals in a specific place, more particularly in the context of breeding. Such fences are very easily movable, so that they allow a rationalization of the grassland. In the opposite case of extensive breeding, the convenience of setting up such fences is sought to minimize their installation time.
- Such an electric fence comprises in known manner, in addition to an energizer, intended to deliver an electric current in the form of very short pulses, of high voltage, typically a few thousand volts, but of low amperage, a fence proper, generally consisting of 'A support made of non-electrically conductive material, in particular made of synthetic material, and electrically conductive wires integrated in this support.
- the support for example made of polyethylene, is typically constituted in the form of a braided, knitted or even woven ribbon, so as to give it, in addition to a certain mechanical resistance to stretching, also good visibility, in particular for animals, considering that it can be very easily colored in the mass.
- these electric fences are intended to be modified fairly regularly in their installation at grassland level, in order to precisely rationalize their use. In this way, they are subjected to numerous folding, unfolding and other rewinds. If such operations have relatively no effect on the support made of synthetic material, on the other hand it was quickly noticed that they affected the electrical conductivity, since locally observed breaks in the conductors. In order to get rid of such breaks, and in particular to compensate for them, in particular in terms of conduction of electricity, it has been proposed to use several conductors, having multiple crossing points, in order to compensate for the local breaks of those -this, ensuring the relay of conduction.
- the document FR-A-2 638 061 describes an electric fence of the type in question, comprising two electric conductors extending longitudinally along the support of the actual fence, and a central conductor, extending from one conductor to another in the form of a zig-zag, and intended precisely to compensate for the local ruptures of one of the lateral conductors.
- the object of the invention is to overcome these various drawbacks. It offers an electric fence, intended for the development of grassland and the protection of crops against intrusion by animals, capable of overcoming any local rupture of electrical conductors, and effective whatever its local conformation, particularly following the different folds and unfolds of which it was the subject.
- This electric fence consists of a flexible support made of a material that does not conduct electricity, integrating an electrically conductive network.
- this network consists of a plurality, and in particular two, of conductive wires, each wire extending periodically from one side edge to the other of said support in a wavy form, and this over the entire length. thereof, said son being offset from each other in the direction of the length so as to cross regularly in the middle of said support, and are distributed in a substantially balanced manner on either side of the support.
- the invention no longer uses lateral conductors connected to each other by a central conductor, but to a plurality of conductors joining the two edges of said strip, and crossing each other so that taking into account the numerous crosses obtained, and whatever the local ruptures of one or more of these conductors, the required conduction is always relayed and therefore ensured, on both sides of said support.
- the support is a knitted fabric
- the electrical conductive wires are integrated into the support during the production of the latter, said electrical conductors being distributed by at least two pass bars of the knitting loom allowing the production of the support, said bars working in opposite directions to one another in an armor such that the electrical conductors are offset from one row of stitches to the next over the entire width of the knitted fabric.
- the support is a knitted mesh knitted fabric produced by two guide bars, one of which works in a chain weave, and the other in a weave transversely connecting said chains together.
- These sets of conductors are advantageously four in number, distributed at a rate of two, on either side of said support in order to ensure equal conduction on both sides of the fence and therefore, free from the hazards of folding and unfolding. that the fence undergoes.
- Figure 1 is a schematic representation of a ribbon constituting the fence according to one of the embodiments of the invention.
- REPLACEMENT SHEET Figure 2 is a schematic representation of another embodiment of the invention.
- FIG. 1 therefore shows a ribbon constituting the electric fence according to the invention.
- This ribbon is produced by knitting from polyethylene threads, typically with a diameter of 0.3 or 0.4 mm, and already dyed in the mass.
- This ribbon playing the role of support, is typically produced on a hook loom, of which at least two guide bars (also called thread throwers) produce the knitting-support.
- the wires of said support are thus distributed in a chain weave (1), linked together by wires (2) ensuring the cohesion of said support, and which can be distributed by a single passette bar (or thrower), but preferably by two different sets.
- Such a crochet loom is described in T'Industrie Textile "of 1968.
- two conductive threads (3,4) are inserted in the knitted support (1,2) during the production of the latter.
- These metallic threads typically made of stainless steel or another metal or conductive metal alloy, of a typical diameter close to 0.15 to 0.20 mm, extend from one side edge (5) to another (6) of the polyethylene support.
- the metal wires (3,4) are integrated into the support (1,2) by two pass bars of the hook loom allowing the support to be produced, said bars working in opposite directions to each other. in an armor such that the electrical conductors (3,4) are offset from one row of stitches to the next over the entire width of the knitted fabric, forming back and forth between the two edges (5,6).
- each of the electrical conductors (3,4) is offset relative to each other in the direction of the length, so as to come to cross at the center of the support (1,2).
- the crossing points of the two conducting wires (3,4) are made in the middle of the same chain point of the support, so as to ensure close and permanent contact between the two wires (3,4), and thus promote electrical conduction from one to the other in the event of local failure inherent in a rupture of one of them.
- the conductors (3, 4) can be multifilamentary (typically from five to ten wires), and are in the form of flat bundles, further increasing the repellency of fences facing live with animals since they increase the contact area with them in case the animal touches the fence.
- said elements (3) or (4) pass alternately above and below the support at each of the binding threads (2) chains (1) constituting the knitted support (1,2).
- a fence strip is obtained comprising electrical conductors in a continuous and balanced manner on each of its faces.
- the conductive son are four in number, distributed in two sets of two conductors.
- each set describes back and forth between the two edges (5,6) of the knitted support (1,2), materializing a wavy profile.
- the two threads of the same set are substantially parallel with respect to each other, and are slightly offset by a distance corresponding to the distance separating two consecutive chains from the knitted support.
- the product is obtained on a knitted loom knitting machine of the "gauge 7" type (seven needles per centimeter), and comprising at least four sets of yarn distributors, known as “ passettes bars “or” thread throwers ", in addition to a set allowing to realize parallel chains.
- the thread throwers are threaded at disposal, that is to say according to an alternation of distributors supplied with wires, and other distributors not comprising a wire. Threading is such that at the end of the loom, a knitted network of about 15 mm in width is obtained, produced on 9 needles. Depending on the width of the loom, and the number of needles n it contains, it is therefore possible to make n / 10 identical strips separated from each other.
- two guide bars are supplied with synthetic yarn (in particular polyethylene horsehair from 0.3 to 0.4 mm in diameter), and are intended to produce, in connection with the chains, the flexible knitted support (1,2), and giving it a structure practically blocked in long and wide;
- synthetic yarn in particular polyethylene horsehair from 0.3 to 0.4 mm in diameter
- the other two guide bars are supplied with conductive metal wire (for example stainless steel 0.15 to 0.20 mm in diameter), and work in opposition, according to an armor distributing the said conductive wires (3,4) in bias from one edge to the other of the knitted strip formed (1,2), and this, so that said conductive threads (3,4) cross in the center of said strip, and that on the edges of that -ci, that is to say in the areas where said conductive wires change direction, they are "trapped" not in the first, respectively the last (ninth) column of stitches, but in the second respectively the penultimate , here the eighth column of meshes.
- conductive metal wire for example stainless steel 0.15 to 0.20 mm in diameter
- a guide bar works in a chain weave so as to form 9 columns of meshes, connected together so as to form a flexible structure which traps the conductive wires.
- Tack ratio 9 columns / 18 rows
- bar 1 distribution of a threading thread: 2 voids / full l / 6 voids armor: 2/3/4/5/6/7/7/8/7/7/6/5/4/3/2 / 2/1/2
- FIG. 1 An article is obtained as illustrated in FIG. 1, in which the two conducting wires are integrated into the knitted network by extending at an angle across the width from one edge to the other of said network and crossing at the level of the middle zone.
- the conducting wires (3,4) being distributed by the external bars, are therefore placed on the external faces of the structure, guaranteeing the optimization of the potential contact of the fence with the animal, and therefore its efficiency.
- due to the specific armor used to connect the chains (1) together it leads to the areas where the conductive wires (3,4) cross, at perfect contact between these last, since there is at this level no connecting thread for the chains.
- bar 1 distribution of a pair of conducting wires, threading: 1 empty / 2 full / 6 empty armor: 1/2/3/3/4/4/5/5/6/7/6/5/5 / 4/4/3/3/2
- the invention therefore quite naturally finds its application in fences for breeding, and all its related uses.
