    [0001] TECHNICAL FIELD The invention relates to a puller hook for the staking of a climbing plant.
    [0002] The invention applies more particularly to the cultivation of tomato plants in a greenhouse. PRIOR ART Inside the greenhouse, each tomato plant is staked by a string that can be left free vertically. This string is held high on a horizontal cable extending parallel to the row to which the tomato plant belongs.
    [0003] In the upper part, the string is wound on a coil attached to the aforementioned support cable. This coil, commonly called "tomato hook" is traditionally made of folded wire, inscribed in a plane (flat coil).
    [0004] At the beginning of the season, the string is vertical, the tomato hook overhanging the young plant. During the season, the plant will grow gradually, and fruiting will take place from bottom to top, in successive clusters.
    [0005] In order to increase the fruit production on the same plant, we try to increase the length of the string during the growth of the plant. In order to obtain this result, the tomato hook is moved progressively and periodically along the horizontal support cable and the tomato hook is unwound a certain length of string to give it "slack" and to allow the tilting of the plant.
    [0006] 3021495 2 This operation is performed by people perched on carts moving along the row of plants; they manipulate one by one each hook, rotate them on themselves to unwind the desired length of twine, and move them one by one on the support cable in a position slightly offset (depending on the length of the support cable) compared at the initial position, to give the string the desired length and curvature.
    [0007] In general, the cable for hooking the tomato hooks is located at a height of about 3 meters above the ground. The length of the string is of the order of 7 meters, which corresponds to a reserve of the order of 4 meters, sufficient for a season.
    [0008] 15 At the beginning of the season, it is necessary to hang on the support cable a tomato hook in line with each young plant. The hooks are delivered by the manufacturers already lined with the string.
    [0009] During this attachment, the operator, perched on a carriage, lets "spin" freely the desired length of initial string, which depends on the height of the cable support hook - itself a function of the height of the greenhouse - for example 3 meters.
    [0010] For this, he returns several times on himself the hook, which acts as a coil, to unwind the right length. For this purpose, he counts each half-turn he prints to the hook by letting the string spin. Thus, if the winding length is 16.5 cm, it will have to print the hook 18 half turns. It is understood that this operation is long and very tedious, especially since it is repetitive, the greenhouse 3021495 3 can house a very large number of tomato plants. It is also a source of errors. In patent FR-2779906, a tomato hook of the type mentioned above is proposed, which, while being inexpensive, has, prewound, a length of twine wrapped in a skein on a first reel and corresponding to the length desired length, this length being perfectly separated from the rest of the string which is wound in skein on a second reel, and can therefore be unwound automatically, without calculation and without risk of error. Thus, the manufacturer provides tomato hooks lined with two skeins of twine so that the length of twine that can be removed first in the first skein corresponds to the desired initial length (function of the greenhouse delivered), for example 3 meters. But before hanging the tomato hook on the support cable, the operator must always unroll the necessary length of twine of the first reel which is an additional operation to the hooking operation of the hook on the support cable. The operator releases for example this first piece of string by tearing the first reel on the tomato hook. The hooking and unwinding operations are therefore two distinct steps that are long, painful and can be tedious, and the present invention aims to simplify them.
    [0011] SUMMARY OF THE INVENTION The idea underlying the invention is to perform the operations of hooking and peeling of the first section of string in a single step. Thus, the object of the invention is to propose a hook for twine for staking a climbing plant, comprising a hook intended to be hooked to a support cable and a reel for receiving a skein of string, characterized in that that the hook and the reel are arranged in such a way that by hooking the hook on the cable, the cable drives the skein of the reel.
    [0012] The puller hook according to the invention may have the following features: it may comprise two hooks respectively disposed at two ends of the reel such that by hanging one or the other of the two hooks 20 on the cable, the cable chase the skein of string from the reel; the hook may comprise a first groove in which the cable engages and the reel may comprise a second groove in which the string of twine is wound, the first groove extending substantially transversely to the second groove; - The wire hook can be formed by folding a wire; it may comprise a first reel intended to receive a first skein of twine and a second reel for receiving a second skein of twine. The invention extends to a trellising device for growing tomatoes, which comprises a spool hook as shown above. BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be better understood and other advantages will appear on reading the detailed description of an embodiment taken by way of non-limiting example and illustrated by the appended drawings in which: FIG. 1 schematically shows a front view of a hook looper according to the invention; Figure 2 shows schematically the spool hook furnished with two skeins of twine; - Figure 3 illustrates the action of the support cable on the skein of string to drive it from the reel; FIG. 4 shows an alternative embodiment of the wire feed hook shown in FIG. 1. FIG. 5 shows trellising devices for tomato plants. DESCRIPTION OF THE EMBODIMENTS A strander hook for twine staking a climbing plant according to the invention is shown in FIG. 1 as reference 1. This is a spool hook which is formed by folding of a wire F and which has a certain mechanical strength and flexibility.
    [0013] It extends in a longitudinal direction A and is symmetrical along the median transverse axis XX '. The folding plane is here along the axes A and XX '. It comprises two hooks at its two opposite ends in the direction A which are intended to hook onto a support cable 14 shown in FIG. 5. The pull-up hook according to the invention illustrated in FIGS. 1 to 5 can be furnished with two skeins 12, 10 13 of twine staking as visible in Figure 2 in particular. Reference 11 in FIG. 2 denotes the staking string which can be several meters long. As can be seen in FIG. 1, the pick-up hook 1 has a rectilinear median body 3 perpendicular to the axis XX 'from which symmetrically two branches 2 extend which extend over a first portion of length first along the direction A in the opposite way. Each branch 2 comprises a second portion of length which extends the first portion of length and which is inclined relative to the direction A outwards (to the left in FIG. 1) of the looper hook 1. The second portion of length The first elbow 4 is extended by means of another section of straight length 6 by a second elbow 5 which itself is extended by means of another portion of the elbow 4. rectilinear length 7 by a third bend 8. The portion of length 7 extends in Figure 1 upwards in the longitudinal direction A.
    [0014] The second bend 5 defines a groove of a reel for the winding of the string 11 of a first skein of twine, here the skein 12 in FIG. 2. The portion of length 7 which is vertical in FIG. 1 serves as 5 stop holding the first skein together with the length portion 6 of the wire F. The length portion 7 is extended by a third bend 8 which is tightened and which constitutes a hook C to be attached to the cable 14 .
    [0015] As can be seen in FIG. 1, the length portion of wire 9 which closes the hook C substantially extends transversely to the longitudinal direction A and has an end bent in the direction A to define another groove. of a reel for the winding of the string 11 of a second skein of twine, here the skein 13 in Figure 2. This end 10 serves as a stop holding the second skein in the second reel. By their design, the branches 2 are sufficiently flexible to have a spring function. Thus during the winding of the skein 13, it is possible to adjust the tension of the string of the skein 13 to obtain a good hold in place of the skein in its reel. The greater the tension 25 in this skein, the harder it will be to disassemble the end of the skein at the bend 8. As an indication, the length between the ends in the direction A of the looper hook in the direction A is of the order of 200mm.
    [0016] As is well known, the wire hook according to the invention is lined with two skeins 12 and 13 made of a single string 11.
    [0017] As can be seen in FIG. 2, the string 11 of the skein 13, which constitutes the secondary skein, is wound on a first reel formed by two opposing winding grooves in the direction A which are each constituted by the length portion of the wire 9 which closes the hook C (and also by the curved end of the wire 10) The string 11 of the main skein, here the skein 12 which has the longest length of 10 string 11, is wound on a second reel which have two winding grooves opposite the direction A which are each constituted by a bend 5. The secondary skein 13 of string is intended to be released from the first reel in one go, in 15 leaving the string to the ground. The length of the string 11 in the skein 13 depends on the height of the hooking cable 14. The main skein 12 of twine is intended to be unwound during the growth of the climbing plant. The length of the string 1 in the main skein 12 may be much greater than that in the secondary skein 13. It is understood that the string 11 is wound unbroken between the two skeins 12 and 13.
    [0018] In Figure 5, there is shown the wire hook 1 according to the invention in the attachment position on the support cable 14, the string 11 of the secondary skein 13 being unrolled to the ground. As can be seen in FIG. 5, the hook 1 30 according to the invention is inclined and it is possible by a simple pull on the string 11 to progressively unwind the main skein 12.
    [0019] According to the invention and as illustrated by the arrow G in FIG. 3, the hook C and the second reel which receives the secondary skein 13 are arranged such that by hooking the hook C (formed by the bend 5 8) on the cable 14, the cable 14 expels the skein 13 of the second reel. More particularly, the user takes in hand the looper hanger 1 lined skeins 12 and 13 of twine according to the invention at the median body 3 and 10 engages the support cable 14 in the groove of the hook hook C. The Cable 14 then exerts a thrust on the loop of secondary skein 13, as illustrated by arrow G in FIG. 3, which is wound on the top of hook C which has the effect of driving out the skein of string 13 its reel, the string 11 then spinning alone by gravity to the ground. This principle applies equally to the two hooks C, C 'in FIG. 1 (formed by the two bends 8, 8') respectively disposed at the two ends of the pick-up hook 1 according to the invention in direction A, so that the The user does not have to think about the hooking direction of the hook 1 on the support cable 14.
    [0020] This therefore makes it possible to simplify and accelerate the installation of trellisers for tomato plants in industrial greenhouses. It will be understood that with the wire hook 1 according to the invention, the inclination of the groove of the hook with respect to the longitudinal direction A can have an effect on the tensile force to be exerted on the hook wire when it is crocheted. on the support cable.
    [0021] 3021495 10 Plus the inclination of the hook groove is close to the perpendicular to this direction A, plus the hooking on the cable 14 with release of the skein of string 13 is facilitated.
    [0022] Furthermore, it will be understood that the coefficient of flexibility of the puller hook according to the invention (flexibility of the wire F in particular) has an influence on this pulling force to be exerted because of the spring effect produced when the skein of twine 10 13 is pushed on the cable during picking. The elasticity of the string can also have an influence on the traction force to be exerted even if this parameter is rather negligible. FIG. 4 illustrates another folding of the wire F to constitute a wire feed according to the invention with a single hook C. In this embodiment, the two reels have common winding grooves. the pulling hook 1 according to the invention could be made of molded plastic material, cut sheet metal, or by successive additions of materials (plastic or metal) such as those used for 3D printing The hook wire 1 according to the invention is well adapted to growing greenhouse tomatoes, but could also be applied to other climbing plants that may require similar stakes.
