Description

Dispositif de tuteurage pour plantes grimpantes Staking device for climbing plants
Domaine technique de l'inventionTechnical field of the invention
L'invention est relative à un dispositif de tuteurage pour plantes grimpantes, au moyen d'un fil support souple sensiblement vertical, comprenant un dévidoir avec des moyens d'accrochage rapide à un câble porteur et une bobine d'enroulement dudit fil support montée à rotation autour d'un axe de rotation.The invention relates to a staking device for climbing plants, by means of a substantially vertical flexible support wire, comprising a reel with means for fast attachment to a carrying cable and a winding reel of said support wire mounted to rotation about an axis of rotation.
État de la techniqueState of the art
Les moyens d'accrochage rapide au câble porteur comprennent généralement un crochet que l'on peut déplacer le long dudit câble qui est tendu horizontalement à une hauteur importante (environ 3 mètres du sol). Le fil support souple, constitué par une corde ou une ficelle, est déroulé depuis le dévidoir. La plante est accrochée et guidée durant sa croissance.The quick hooking means to the carrying cable generally comprise a hook that can be moved along said cable which is stretched horizontally at a high height (about 3 meters from the ground). The flexible support wire, consisting of a rope or string, is unwound from the reel. The plant is hooked and guided during its growth.
On a développé, lors des dernières années, la méthode de culture « à croissance à prolongement latéral » principalement utilisée, à ce jour, pour la culture des tomates en serre.In recent years, the "growth method with lateral extension" has been developed, mainly used, to date, for the cultivation of greenhouse tomatoes.
Selon cette méthode, la jeune plante est accrochée au fil support vertical se déroulant depuis le dévidoir accroché, sensiblement à la verticale de ladite plante, sur le câble porteur tendu horizontalement à proximité du toit de la serre, c'est-à-dire, généralement à plusieurs mètres du sol. Ce câble sustentateur est disposé au-dessus d'un alignement de plantes espacées en fonction de la nature de ces dernières. La plante est guidée par le fil support durant sa croissance et elle est fixée sur celle-ci au fur et à mesure de son développement, au moyen d'attaches appropriées.According to this method, the young plant is hooked on the vertical support wire taking place from the hooked reel, substantially vertically to said plant, on the carrier cable stretched horizontally near the roof of the greenhouse, that is to say, usually several meters above the ground. This lift cable is disposed over an alignment of plants spaced according to the nature of the latter. The plant is guided by the support wire during its growth and is fixed on it as and when it develops, by means of appropriate fasteners.
Lorsque la partie aérienne porteuse de fruits de la plante atteint une hauteur la rendant difficilement accessible, une certaine longueur supplémentaire de fil support est déroulée et le dévidoir est déplacé le long du câble porteur. Ainsi, la partie inférieure improductive de la plante forme une courbe qui vient reposer sur le sol. Cette opération est renouvelée à plusieurs reprises durant la croissance des plantes qui peuvent atteindre des longueurs supérieures à douze mètres (par exemple dans le cas des tomates).When the aerial part carrying fruit of the plant reaches a height making it difficult to access, a certain additional length of support wire is unwound and the reel is moved along the carrier cable. Thus, the unproductive bottom part of the plant forms a curve that comes to rest on the ground. This operation is repeated several times during the growth of plants that can reach lengths greater than twelve meters (for example in the case of tomatoes).
Cette méthode de culture permet d'augmenter le rendement des surfaces cultivées, et de réaliser des économies de main d'œuvre et d'achat de jeunes plantes.This method of cultivation makes it possible to increase the yield of the cultivated surfaces, and to save labor and purchase young plants.
Le document FR-A-2743258 décrit un dispositif du type mentionné ci-dessus, dans lequel l'un des rebords de la bobine est muni d'un loquet. Le porte- bobine comprend un levier de verrouillage comportant une partie orientée transversalement et disposée sur la trajectoire circulaire du loquet. Une deuxième partie s'élève dans une direction parallèle à une portion intermédiaire du porte-bobine et à distance réduite de l'un des cotés de ladite portion intermédiaire.FR-A-2743258 discloses a device of the type mentioned above, wherein one of the flanges of the coil is provided with a latch. The coil carrier comprises a locking lever having a transversely oriented portion and disposed in the circular path of the latch. A second portion rises in a direction parallel to an intermediate portion of the reel holder and at a reduced distance from one side of said intermediate portion.
Pour obtenir la libération d'une longueur de fil support, il est nécessaire de prendre en main la portion intermédiaire sans décrocher le dévidoir du câble, et d'exercer une pression sur la deuxième partie du levier de verrouillage, en resserrant la main, pour la rapprocher de la portion intermédiaire. Ceci a pour effet de provoquer le pivotement vers le haut de la première partie du levier et le déverrouillage du loquet se trouvant en butée contre la première partie. Lorsqu'il s'agit de dérouler les premiers mètres de fil support nécessaires à l'accrochage de la jeune plante, il faut tirer vers le bas, avec l'autre main, sur l'extrémité libre du fil support, pour obtenir le déroulement de la longueur souhaitable. On procède sensiblement de la même façon lorsqu'il s'agit de libérer des longueurs supplémentaires ; dans ce cas toutefois, on prend d'abord en main l'extrémité supérieure de la ficelle déroulée qui soutient la plante, et on bascule ensuite avec l'autre main le levier en direction de la portion intermédiaire.To obtain the release of a length of support wire, it is necessary to take hold of the intermediate portion without detaching the reel of the cable, and to exert pressure on the second part of the locking lever, by tightening the hand, to bring it closer to the intermediate portion. This has the effect of causing the first part of the lever to pivot upwards and the latch unlocking being in abutment with the first part. When it comes to unrolling the first few meters of support wire needed to hang the young plant, pull it down, with the other hand, on the free end of the support wire, to obtain the unwinding of the desirable length. The procedure is much the same when it comes to releasing additional lengths; in this case, however, first takes in hand the upper end of the unrolled string which supports the plant, and then we switch with the other hand the lever in the direction of the intermediate portion.
Un tel dispositif simple et bon marché a cependant pour inconvénient de nécessiter la répétition d'efforts importants pour soulever le fil support déroulé sur lequel est accroché la plante (laquelle peut représenter une masse de l'ordre de 10 à 20kg), pour permettre la rotation contrôlée de la bobine de fil selon un nombre correspondant à la longueur supplémentaire de celui-ci que l'on souhaite dérouler. L'utilisateur doit nécessairement utiliser simultanément ses deux mains. Aucune de ses mains ne peut alors agripper une rambarde de sécurité pour éviter les chutes en hauteur. A défaut, il est possible de dérouler la bobine par saccades en repositionnant le levier de verrouillage contre le loquet à chaque tour. Mais ces saccades se répercutent alors sur la plante grimpante et risquent de provoquer la chute involontaire de fruits. Compte tenu du fait que ces manipulations incommodes sont effectuées à plus de 3 mètres du sol, on comprend que ce travail devient très pénible si l'on considère qu'une serre peut nécessiter l'emploi de plusieurs milliers de dispositifs de tuteurage. Par ailleurs, il n'est pas possible de régler avec précision la longueur supplémentaire de fil support déroulé, car cette longueur correspond obligatoirement à un multiple de tour de bobine.Such a simple and inexpensive device, however, has the disadvantage of requiring the repetition of major efforts to lift the support wire unrolled on which is hung the plant (which can represent a mass of the order of 10 to 20kg), to allow the controlled rotation of the reel of thread according to a number corresponding to the additional length of the latter which is to be unwound. The user must necessarily use both hands simultaneously. None of his hands can grab a guardrail to avoid falls from a height. Otherwise, it is possible to unroll the coil by jerking by repositioning the locking lever against the latch each turn. But these saccades then reverberate on the climbing plant and may cause the involuntary fall of fruit. Given the fact that these inconvenient manipulations are carried out more than 3 meters from the ground, we understand that this work becomes very painful considering that a greenhouse may require the use of several thousand staking devices. Moreover, it is not possible to precisely adjust the additional length of the support wire unwound, because this length necessarily corresponds to a multiple of coil revolution.
Objet de l'inventionObject of the invention
L'objet de l'invention consiste à réaliser un dispositif de tuteurage simple, d'utilisation facile, permettant de libérer une longueur quelconque de fil support, et pouvant être manipulé d'une seule main. Selon l'invention, ce but est atteint par le fait que le dévidoir comporte : un levier de blocage monté à pivotement autour d'un axe de pivotement entre une position de serrage du fil support et une position de libération, le fil support étant disposé en position de serrage entre une première mâchoire solidaire du levier de blocage et une deuxième mâchoire fixe opposée à la première mâchoire, et des moyens automatiques de rappel du levier de blocage vers la position de serrage.The object of the invention is to provide a simple, easy-to-use staking device which makes it possible to release any length of support wire and which can be handled with one hand. According to the invention, this object is achieved by the fact that the reel comprises: a locking lever pivotally mounted about a pivot axis between a clamping position of the support wire and a release position, the support wire being disposed in the clamping position between a first jaw integral with the locking lever and a second fixed jaw opposite the first jaw, and automatic means for returning the locking lever to the clamping position.
En position de serrage, les mâchoires pincent le fil support et assurent sa retenue par friction. L'effort radial de serrage est suffisant pour créer un effort longitudinal de retenue s'opposant au poids du fil déroulé et de la plante attachée. Une pression manuelle appliquée sur une surface d'appui du levier de blocage engendre un couple de rotation opposé à celui exercé par les moyens de rappel, de manière à provoquer l'écartement des première et deuxième mâchoires. Ce mouvement entraîne la libération progressive, c'est-à-dire sans saccades, et instantanée du fil support, qui se déroule depuis la bobine sous l'effet du poids de la plante. Plus la pression manuelle est élevée, plus l'effort radial de serrage diminue, de même que l'effort longitudinal de retenue. Ainsi, simplement en ajustant la pression exercée, l'utilisateur peut contrôler très précisément la longueur de fil support déroulé automatiquement, laquelle longueur peut être quelconque. Lorsque ladite longueur correspond à la longueur désirée, il suffit à l'utilisateur de relâcher la pression manuelle. Cette manipulation se pratique très simplement, à une seule main, avec un minimum d'efforts grâce à la simple nécessité d'appliquer un effort presseur sur la surface d'appui du levier de blocage.In the clamping position, the jaws pinch the support wire and ensure its retention by friction. The radial clamping force is sufficient to create a longitudinal retaining force opposing the weight of the unwound wire and the attached plant. Manual pressure applied to a bearing surface of the locking lever generates a torque opposite to that exerted by the biasing means, so as to cause the spacing of the first and second jaws. This movement causes the gradual release, that is to say without jerks, and instantaneous support wire, which unwinds from the coil under the effect of the weight of the plant. The higher the manual pressure, the less the radial clamping force decreases, as well as the longitudinal retaining force. Thus, simply by adjusting the pressure exerted, the user can control very precisely the length of support wire unrolled automatically, which length can be any. When said length corresponds to the desired length, it is sufficient for the user to release the manual pressure. This manipulation is practiced very simply, with one hand, with minimal effort due to the simple need to apply a pressure force on the bearing surface of the locking lever.

Description d'un mode préférentiel de l'inventionDescription of a preferred embodiment of the invention
En référence aux figures, un exemple de dispositif de tuteurage selon l'invention comporte un dévidoir 10 ayant un support 11 muni d'un cadre plan 24 rectangulaire. Le dévidoir 10 se compose en outre d'une bobine 12 d'enroulement d'un fil support 13 souple. La bobine 12 est supportée par le support 11. Le dévidoir 10 est destiné à être accroché à un câble porteur (non représenté) disposé à plusieurs mètres du sol, sensiblement à la verticale d'un alignement de plantes espacées en fonction de leur nature. A cet effet, une face arrière 14 du cadre plan 24 comporte dans sa partie supérieure un crochet 15 s'étendant sur toute sa largeur. Ces moyens d'accrochage classique permettent un accrochage rapide du dévidoir 10 sur le câble porteur, ainsi qu'un déplacement aisé et très rapide du dévidoir 10 le long du câble, parfaitement contrôlable par l'utilisateur. Le dévidoir 10 permet de libérer un brin libre 16 de fil support 13 par déroulement de la bobine 12. Le brin libre 16 est destiné à s'étendre sensiblement verticalement jusqu'au sol pour permettre la fixation et le guidage de la plante grimpante durant sa croissance, au moyen d'attaches appropriées. Le fil support 13, de section quelconque, peut être une ficelle, une corde, ou tout autre élément en matière souple et adaptée. Pour assurer la fixation facile et amovible de la bobine 12 sur le support 11, un manchon de montage 18 tubulaire s'étend perpendiculairement depuis la face avant 17 du cadre plan 24 opposée à la face arrière 14, à la même hauteur que le crochet 15. Une butée de retenue 19 fait saillie de la surface extérieure du manchon de montage 18 au niveau de son extrémité distale, c'est-à-dire l'extrémité opposée à l'extrémité de raccordement au cadre plan 24. La butée de retenue 19 se compose d'un épaulement interne 20 raccordé à la surface extérieure du manchon de montage 18, et d'un chanfrein externe 21. Pour constituer la butée de retenue 19, le diamètre de la surface externe cylindrique raccordant l'épaulement interne 20 et le chanfrein externe 21 est supérieur au diamètre intérieur du moyeu 23 de la bobine 12.With reference to the figures, an exemplary staking device according to the invention comprises a reel 10 having a support 11 provided with a rectangular planar frame 24. The reel 10 is furthermore composed of a coil 12 for winding a flexible support wire 13. The coil 12 is supported by the support 11. The reel 10 is intended to be attached to a carrier cable (not shown) disposed several meters from the ground, substantially vertically to a line of plants spaced according to their nature. For this purpose, a rear face 14 of the planar frame 24 has in its upper part a hook 15 extending over its entire width. These conventional attachment means allow rapid attachment of the reel 10 on the carrier cable, as well as easy and very fast movement of the reel 10 along the cable, perfectly controllable by the user. The reel 10 makes it possible to release a free strand 16 of the support wire 13 by unwinding the reel 12. The free strand 16 is intended to extend substantially vertically to the ground to allow the fixing and guiding of the climbing plant during its growth, by means of appropriate fasteners. The support wire 13, of any cross section, may be a string, a rope, or any other flexible material adapted element. To ensure the easy and removable attachment of the coil 12 on the support 11, a tubular mounting sleeve 18 extends perpendicularly from the front face 17 of the flat frame 24 opposite to the rear face 14, at the same height as the hook 15 A retaining stopper 19 protrudes from the outer surface of the mounting sleeve 18 at its distal end, i.e., the end opposite the end of connection to the planar frame 24. The retaining stopper 19 consists of an inner shoulder 20 connected to the outer surface of the mounting sleeve 18, and an outer bevel 21. To form the retaining stop 19, the diameter of the cylindrical outer surface connecting the inner shoulder 20 and the outer chamfer 21 is greater than the inside diameter of the hub 23 of the coil 12.
Afin d'autoriser la mise en place du moyeu 23 de la bobine 12 sur la surface extérieure du manchon de montage 18, des lumières rectilignes 22 s'étendent axialement depuis l'extrémité distale du manchon de montage 18.In order to allow the hub 23 of the coil 12 to be placed on the outer surface of the mounting sleeve 18, rectilinear slots 22 extend axially from the distal end of the mounting sleeve 18.
Lors de la mise en place de la bobine 12, les lumières rectilignes 22 favorisent la déformation radiale du manchon 18 en direction de son axe de révolution. Le chanfrein externe 21 facilite l'engagement de la bobine 12 par l'extrémité libre du manchon 18 en transformant ce mouvement axial en une déformation radiale du manchon 18. Par retour élastique de la matière constitutive du manchon 18, l'épaulement interne 20 assure ensuite la retenue du moyeu de la bobine 12. La bobine 12 se trouve alors montée à rotation autour d'un axe de rotation correspondant à l'axe de révolution du manchon de montage 18.During the installation of the coil 12, the rectilinear lights 22 promote the radial deformation of the sleeve 18 in the direction of its axis of revolution. The outer chamfer 21 facilitates the engagement of the coil 12 by the free end of the sleeve 18 by transforming this axial movement into a radial deformation of the sleeve 18. By elastic return of the constituent material of the sleeve 18, the inner shoulder 20 ensures then the retention of the hub of the coil 12. The coil 12 is then mounted to rotate about an axis of rotation corresponding to the axis of revolution of the mounting sleeve 18.
De manière classique, les extrémités du moyeu 23 de la bobine supportent des flancs 25a, 25b disposés perpendiculairement, dont l'un 25a est muni d'un trou de départ 26 pour le passage de l'extrémité du brin enroulé du fil support 13 afin de pouvoir réaliser sa fixation à l'extérieur du flanc 25a, par exemple grâce à la constitution d'un nœud. Le support 11 comporte, en outre, une première paroi 27 raccordée perpendiculairement à la face avant 17 du cadre plan 24 et orientée pour être parallèle à la direction du câble porteur lorsqu'il est inséré dans le crochet 15. Deux nervures 28 renforcent la rigidité entre le cadre plan 24 et la première paroi 27. La première paroi 27 est disposée en dessous du manchon de montage 18.Conventionally, the ends of the hub 23 of the coil support sides 25a, 25b arranged perpendicularly, one of which 25a is provided with a starting hole 26 for the passage of the end of the wound strand of the support wire 13 so to be able to achieve its fixing outside the flank 25a, for example by the constitution of a node. The support 11 further comprises a first wall 27 connected perpendicularly to the front face 17 of the flat frame 24 and oriented to be parallel to the direction of the carrying cable when it is inserted in the hook 15. Two ribs 28 reinforce the rigidity between the plane frame 24 and the first wall 27. The first wall 27 is disposed below the mounting sleeve 18.
Une deuxième paroi 29 s'étend en dessous et parallèlement à la première paroi 27. Deux nervures 46 renforcent la rigidité entre le cadre plan 24 et la deuxième paroi 27. Les première et deuxième parois 27, 29 sont reliées par une troisième paroi 30 parallèle au cadre plan 24. L'ensemble constitué par le cadre plan 24 et par les parois 27, 29, 30 délimite un compartiment 34 communiquant avec l'extérieur, destiné à être traversé par le fil support 13 (figure 4), et ayant à cet effet une ouverture d'entrée 31 du fil support 13 provenant de la bobine 12 (à gauche sur la figure 4) et une ouverture de sortie 32 (à droite sur la figure 4).A second wall 29 extends below and parallel to the first wall 27. Two ribs 46 reinforce the rigidity between the flat frame 24 and the second wall 27. The first and second walls 27, 29 are connected by a third wall 30 parallel 24. The assembly constituted by the plane frame 24 and the walls 27, 29, 30 delimits a compartment 34 communicating with the outside, intended to be traversed by the support wire 13 (FIG. 4), and having to this effect an inlet opening 31 of the support wire 13 coming from the coil 12 (on the left in FIG. 4) and an outlet opening 32 (on the right in FIG. 4).
Selon l'invention, le support 11 comporte un levier de blocage 33 allongé suivant une direction principale qui est parallèle à la direction du câble porteur lorsqu'il est inséré dans le crochet 15. Le levier de blocage 33 traverse le compartiment 34 et débouche à l'extérieur par les ouvertures 30 et 31. La face inférieure 35 du levier de blocage 33, en vis-à-vis de la deuxième paroi 29, est connectée à la deuxième paroi 29 par une jonction rectiligne 36 en matériau déformable élastique. La jonction 36 constitue un axe de pivotement du levier de blocage 33 qui est parallèle à l'axe de rotation de la bobine 12.According to the invention, the support 11 comprises a locking lever 33 elongate in a main direction which is parallel to the direction of the carrying cable when it is inserted in the hook 15. The locking lever 33 passes through the compartment 34 and opens at the outside by the openings 30 and 31. The lower face 35 of the locking lever 33, vis-à-vis the second wall 29, is connected to the second wall 29 by a rectilinear junction 36 elastic deformable material. The junction 36 constitutes a pivot axis of the locking lever 33 which is parallel to the axis of rotation of the coil 12.
De part et d'autre de la jonction rectiligne 36 dans la direction principale du levier de blocage 33, la jonction rectiligne 36 définit de manière fictive une première portion (à gauche sur la figure 4) et une deuxième portion (à droite sur la figure 4) du levier de blocage 33, qui sont respectivement référencées 33a et 33b. En d'autres termes, la première portion 33a du levier de blocage 33 est la partie du levier de blocage 33 délimitée par la jonction rectiligne 36 suivant la direction principale, et qui s'étend au travers de l'ouverture d'entrée 31. La deuxième portion 33b est constituée par le reste du levier de blocage 33. Dans la variante représentée, la deuxième portion 33b s'étend dans le prolongement de la première portion 33a et s'étend au travers de l'ouverture de sortie 32.On either side of the rectilinear junction 36 in the main direction of the locking lever 33, the rectilinear junction 36 fictitiously defines a first portion (on the left in FIG. 4) and a second portion (on the right in FIG. 4) of the locking lever 33, which are respectively referenced 33a and 33b. In other words, the first portion 33a of the locking lever 33 is the part of the locking lever 33 delimited by the rectilinear junction 36 in the main direction, and which extends through the inlet opening 31. The second portion 33b is constituted by the rest of the locking lever 33 In the variant shown, the second portion 33b extends in the extension of the first portion 33a and extends through the outlet opening 32.
Dans la première portion 33a, la face supérieure 37 du levier de blocage 33 comporte une surface d'appui 38 plane disposée à l'extérieur du compartiment 34, et un bombement 39 en forme de cylindre partiel, muni extérieurement de crans agencés dans la direction axiale du bombement 39. Le bombement 39 est situé à l'intérieur du compartiment 34.In the first portion 33a, the upper face 37 of the locking lever 33 has a flat bearing surface 38 disposed outside the compartment 34, and a bulge 39 in the form of a partial cylinder, externally provided with notches arranged in the direction axial of the bulge 39. The bulge 39 is located inside the compartment 34.
Depuis la configuration naturelle du levier de blocage 33, qui dépend de l'agencement de la jonction 36, une pression manuelle appliquée sur la surface d'appui 38 provoque le pivotement du levier de blocage 33 de telle manière que la première portion 33a s'éloigne de la première paroi 27 et que la deuxième portion 33b s'en rapproche. Lorsqu'on supprime cette pression, le levier de blocage 33 revient automatiquement dans sa configuration naturelle par retour élastique de la matière constitutive de la jonction rectiligne 36.Since the natural configuration of the locking lever 33, which depends on the arrangement of the junction 36, a manual pressure applied on the bearing surface 38 causes the pivoting of the locking lever 33 so that the first portion 33a s' away from the first wall 27 and the second portion 33b approaches it. When this pressure is removed, the locking lever 33 automatically returns to its natural configuration by elastic return of the constituent material of the rectilinear junction 36.
Dans la configuration naturelle du levier de blocage 33, le sommet du bombement 39 est situé à distance de la première paroi 27. Cette distance est inférieure à la section du fil support 13. De ce fait, lorsque le fil support 13 provenant de la bobine 12 traverse le compartiment 34 en passant au- dessus du levier de blocage 33, le fil support 13 se trouve serré entre la première paroi 27 et le bombement 39 (figure 4). Ce phénomène est considérablement renforcé par la tension exercée vers le bas sur le brin libre 16 par le poids de la plante. Cette tension provoque un moment de rotation du levier de blocage 33 dans le sens du serrage du fil support 13. Outre l'augmentation de l'effort de serrage du fil support 13, ce moment de rotation permet de rappeler le levier de blocage 33 vers la position de serrage lorsque celui-ci en est écarté.In the natural configuration of the locking lever 33, the crown of the crown 39 is located at a distance from the first wall 27. This distance is smaller than the section of the support wire 13. As a result, when the support wire 13 coming from the coil 12 passes through the compartment 34 passing over the locking lever 33, the support wire 13 is clamped between the first wall 27 and the bulge 39 (Figure 4). This phenomenon is considerably reinforced by the tension exerted downward on the free strand 16 by the weight of the plant. This tension causes a moment of rotation of the locking lever 33 in the tightening direction of the support wire 13. In addition to increasing the clamping force of the support wire 13, this torque allows to return the locking lever 33 to the clamping position when it is removed.
Du côté de l'ouverture de sortie 32, la troisième paroi 30 est prolongée par une aile de maintien 40 ayant pour but de guider le fil support 13 sortant du compartiment 34. Un élément de renfort 41 en forme générale de L relie le cadre plan 24 et l'aile de maintien 40 en passant en dessous de la deuxième portion 33b du levier de blocage 33. Le fil support 13 sortant du compartiment 34 constitue le brin libre 16 et peut s'étendre jusqu'au sol.On the side of the outlet opening 32, the third wall 30 is extended by a holding flange 40 intended to guide the support wire 13 coming out of the compartment 34. A generally L-shaped reinforcing element 41 connects the plane frame 24 and the holding flange 40 passing below the second portion 33b of the locking lever 33. The support wire 13 coming out of the compartment 34 constitutes the free end 16 and can extend to the ground.
Pour augmenter la précision du guidage du fil support 13 en amont du compartiment 34 dans la direction de déroulement, le bord supérieur de l'ouverture d'entrée 31 , c'est-à-dire le bord latéral correspondant de la face inférieure de la première paroi 29, comporte une première gorge 42 orientée vers le bas parallèlement à la direction principale du levier de blocage 33. De même en aval du compartiment 34, une deuxième gorge 43 est pratiquée dans la face supérieure 37 du levier de blocage 33 à l'extrémité distale de la deuxième portion 33b. La deuxième gorge 43 est orientée vers le bas parallèlement à la direction principale du levier de blocage 33.To increase the accuracy of the guide of the support wire 13 upstream of the compartment 34 in the unwinding direction, the upper edge of the inlet opening 31, that is to say the corresponding lateral edge of the lower face of the first wall 29, has a first groove 42 pointing downwards parallel to the main direction of the locking lever 33. Similarly downstream of the compartment 34, a second groove 43 is formed in the upper face 37 of the locking lever 33 to the distal end of the second portion 33b. The second groove 43 is oriented downwards parallel to the main direction of the locking lever 33.
La face inférieure 35 du levier de blocage 33 comporte deux pans 35a et 35b convergents en direction de la jonction rectiligne 36. Pour un gain de poids, des évidements 44 sont pratiqués dans les pans 35a, 35b.The lower face 35 of the locking lever 33 comprises two sections 35a and 35b converging towards the rectilinear junction 36. For a saving in weight, recesses 44 are formed in the panels 35a, 35b.
Dans la variante représentée, une aile de déport 45 s'étend latéralement depuis la nervure 28 située au-dessus de la première gorge 42. L'aile de déport 45 assure le renvoi du brin de fil support 13 tendu entre la bobine 12 et la première gorge 42. Cette disposition limite la détérioration du fil support 13 pendant son déroulage et diminue les efforts nécessaires au déroulage.In the variant shown, an offset wing 45 extends laterally from the rib 28 located above the first groove 42. The offset wing 45 ensures the return of the strand of support wire 13 stretched between the coil 12 and the first groove 42. This provision limits the deterioration of the support wire 13 during unwinding and reduces the efforts required for unwinding.
D'après ce qui précède, on comprend que le levier de blocage 33 est monté à pivotement entre une position de serrage du fil support 13 et une position de libération, le fil support 13 étant disposé en position de serrage entre le bombement 39 la première paroi 27. La jonction rectiligne 36 et le moment de rotation créé par la tension exercée sur le brin libre 16 par le poids de la plante constituent des moyens automatiques de rappel du levier de blocage 33 vers la position de serrage. Le bombement 39 et la première paroi 27 constituent respectivement une première et une deuxième mâchoires dans l'action de serrage du fil support 13.From the above, it is understood that the locking lever 33 is pivotally mounted between a clamping position of the support wire 13 and a position release, the support wire 13 being arranged in the clamping position between the bulge 39 the first wall 27. The rectilinear junction 36 and the torque created by the tension exerted on the free end 16 by the weight of the plant constitute means automatic return of the locking lever 33 to the clamping position. The bulge 39 and the first wall 27 respectively constitute first and second jaws in the clamping action of the support wire 13.
Il est clair que le rappel automatique du levier de blocage 33 vers la position de serrage peut être réalisé par tout moyen approprié, par exemple à l'aide d'un ressort de torsion.It is clear that the automatic return of the locking lever 33 to the clamping position can be achieved by any appropriate means, for example by means of a torsion spring.
Lorsque le fil support 13 provenant de la bobine 12 traverse le compartiment 34 en passant au-dessus du levier de blocage 33, et que le levier de blocage 33 est en position de serrage (figure 4), ces mâchoires pincent le fil support 13 et assurent sa retenue par friction. Les caractéristiques dimensionnelles du levier de blocage 33 et structurelles de la jonction rectiligne 36 sont choisies pour que l'effort radial de serrage du fil support 13 soit suffisant pour créer un effort longitudinal de retenue s'opposant au poids du brin libre 16 et de la plante attachée. Pour un poids donné de la plante, l'effort radial de serrage dépend de la distance séparant, dans la direction principale du levier de blocage 33, la deuxième gorge 43 et le bombement 39. Une pression manuelle appliquée sur la surface d'appui 38 engendre un couple de rotation opposé à celui exercé par les moyens de rappel, de manière à provoquer l'écartement du bombement 39 par rapport à la première paroi 27. Ce mouvement entraîne la libération progressive, c'est-à-dire sans saccades, et instantanée du fil support 13, qui se déroule depuis la bobine 12 sous l'effet du poids de la plante. La longueur du brin libre 16 augmente. Plus la pression manuelle est élevée, plus l'effort radial de serrage diminue, de même que l'effort longitudinal de retenue. Ainsi, simplement en ajustant la pression exercée, l'utilisateur peut contrôler très précisément la longueur de fil support 13 déroulé automatiquement, laquelle longueur peut être quelconque. Lorsque ladite longueur correspond à la longueur désirée, il suffît à l'utilisateur de relâcher la pression manuelle. Cette manipulation se pratique très simplement, à une seule main, avec un minimum d'efforts grâce à la simple nécessité d'appliquer un effort presseur sur la surface d'appui 38 du levier de blocage 33. When the support wire 13 coming from the spool 12 passes through the compartment 34 passing over the locking lever 33, and the locking lever 33 is in the clamping position (FIG. 4), these jaws pinch the support wire 13 and ensure its retention by friction. The dimensional characteristics of the blocking lever 33 and structural of the rectilinear junction 36 are chosen so that the radial clamping force of the support wire 13 is sufficient to create a longitudinal retaining force opposing the weight of the free strand 16 and the attached plant. For a given weight of the plant, the radial clamping force depends on the distance separating, in the main direction of the locking lever 33, the second groove 43 and the bulge 39. A manual pressure applied to the bearing surface 38 generates a torque opposite to that exerted by the return means, so as to cause the separation of the bulge 39 relative to the first wall 27. This movement causes the gradual release, that is to say without saccades, and instant support wire 13, which takes place from the coil 12 under the effect of the weight of the plant. The length of the free strand 16 increases. The higher the manual pressure, the less the radial clamping force decreases, as well as the longitudinal retaining force. Thus, simply by adjusting the pressure exerted, the user can control very precisely the length of support wire 13 unwound automatically, which length can be any. When said length corresponds to the desired length, it is sufficient for the user to release the manual pressure. This manipulation is practiced very simply, with one hand, with a minimum of effort thanks to the simple need to apply a pressure force on the bearing surface 38 of the locking lever 33.
