It is known in gardening that, for the cultivation of certain plants, these can be guided along a cord such as a rope or the like. This technique applies to numerous manipulations in the cultivation of tomatoes in bunches.

As the growth of the plant, this should always be fixed to a later place, respectively upper cord. At the present time it is used this feature by cord fixing, manually, of clamping devices for plants, it is obvious that it is about a complicated activity

The present invention aims at a procedure that allows to obtain a fast fixation of a support of this type, as a result of a plant with a cord.

For this purpose the invention relates to a procedure for fixing a support for a plant with a cord, which has the characteristic of: applying a plurality of supports on a reserve support of a device; present this device to a cord; and present to cord, with the help of means that are part of the device, a support from the aforementioned reservation support; set locally, with the help of these means, the cord support; and provide well a fastening part that surrounds or can at least partially surround to the stem of the plant to be fixed.

Because, according to the procedure of the invention, the brackets are automatically fixed by means of a device with cord, manual handling is limited to the presentation of the device with cord, so that it is limited considerably the time required for fixing a support with a cord, in relation to the completely manual procedure. Similarly, by using a device that is equipped with a backup stand, you no longer have to grab a new support The inconvenience that existed previously, of a more precisely the fact that these supports, which are preserved in a sack or in another container, they intermingled and should separate one by one through manipulations that required time, It is also eliminated in this way.

Preferably, the device is provided with a seat for a cord and the device is presented during the fixing the support in such a way that the cord is housed in the seat. In this way, we obtain that each support can be presented to the cord by means of an easy manipulation.

Preferably, in the course of fixing of the support to the cord, support means will be presented behind the cord, so that this always takes a position perfectly defined at the height of the device; this way, you get certainly that each support is fixed exactly on the cord.

The fixing of the support on the cord has place preferably by means of a tightening so that it should not undergo the cord for any specific treatment.

In a practical embodiment, it is used a support that is equipped with a fixing part for the plant, which consists of two elements that can form together an annular passage for the plant stem, by closing means to keep together in closed state in annular form to the two elements mentioned, and for a tightening part that found between the two elements mentioned and that can be folded down and, in this way, tighten around the cord; the support it is presented with the tightening part mentioned against the cord, while the two aforementioned elements are in a state open to each other; and the two elements pivot towards each other of so that the tightening part is folded around the cord and the two mentioned elements are locked in closed state with help of closing means.

In addition, preferably, use is made of a series of fixed supports to each other, which are detached in the device one-to-one automatically, so that the brackets cannot get tangled up with each other

The invention also relates to a procedure for fixing a plant with a cord by which this plant is fixed by applying a support on a cord according to the procedure indicated above and by which, of Simultaneous way to fix the support to the cord, the plant It is surrounded by the aforementioned fixing part.

The invention also relates to the device for performing the aforementioned procedure, for which this device is intended to attach to a cord a support of the aforementioned type whose characteristic lies in the fact that it is constituted mainly by a frame, by a support of reserve for the supports to be applied on the cord, and by means for presenting respectively a support to the cord, from of the reservation support mentioned above, fix the support to the cord and, if necessary, provide a fastening part that surrounds or that may at least partially surround the stem of a plant.

In addition, the invention also relates to brackets that can be fixed on a cord by means of device mentioned above. Other features and others particularities of the aforementioned device, as well as of the supports are explained in the detailed description as well as in the corresponding claims.

Figures 21 and 22 also represent two variants of a support according to the invention.

As depicted in Figure 1, the invention relates to a method for fixing a floor 1 with a cord 2, by means of a support 3 that leaves subsist a free passage 4 for the stem 5 of the floor 1, but which is attached to the cord 2 such that a force is obtained vertical bearing A cord of this type 2 is suspended from known way with a cable or the like.

In order to better understand the device and procedure described above, described now firstly the structure of the support 3. As it has been represented in figures 1 to 3, this support 3 is constituted by a tightening part 6, suitable for closing, whereby the support 3 can be tightened around cord 2; by a part of fixing 7, which can surround, forming a loop, to the stem 5 to less in part, but completely in the example shown; and by 8-9 clamping parts that allow carrying, with support of fastening means, at least the tightening part 6, in the example also the fixing part 7, from the open state until the closed state.

The tightening part 6 is mainly formed by a seat 10 formed by a part of matter relatively thin that can be folded around cord 2, so that this Last be tight. As can be seen in Figure 3, the effect of tightening can be increased by means of profiles 11 on the surfaces Of tightening. One or more parts 12 in the form of hooks make the seat 10 completely surrounds the cord in the depressed state.

The fixing part 7 is composed of two elements 13 and 14, in the form of tightening collars that found respectively on either side of the clamping part 6 and, in assembled state, define the passage in the form of loop 4. In the free extremities of elements 13 and 14 have been applied closure parts suitable for engaging each other, respectively in the form of an opening 15 and an interlocking element 16 which It can snag elastic, giving rise to a closure.

The aforementioned clamping parts 8 and 9 are formed by the extreme surfaces of elements 13 and 14 that present, for this purpose, preferably, but not necessarily, a smooth outer surface.

The support 3 has been made in one piece With a synthetic matter.

In order to fix the brackets 3 to the cord 2 represented in figures 1 to 4, according to the operating mode described in the introduction, the invention proposes a device 17 as depicted in figures 5 to 20.

This device 17 is constituted mainly by a frame 18, by a stand 19 for the supports 3 to be applied on the cord 2, and by means 20 to present respectively to the cord 2 a support 3 from the Reserve support mentioned above 19, fix support 3 to cord 2 and, if necessary, provide a fixing part 7 that surround or that may at least partially surround the stem 5 of a 1st floor

The aforementioned means 20 are constituted, mainly, by a presentation part 21 with which the device 17 can be presented to the cord 2, by a mechanism of displacement 22 to drive one by one to the supports 3 in the sense of presentation part 21 and for its fixation on the cord 2, and by a feeding mechanism 23 to feed the brackets 3 from the backup bracket 2, one by one, at displacement mechanism 22.

The reserve holder 19 is constituted by a cartridge in the form of a guide 24, which is formed by a slot practiced between two elements of delimitation 25 and 26, in which you can apply a series of brackets 3. If necessary they are used, according to the invention, supports 3 that adhere to each other, through the thin material parts 27 to form a band.

The presentation part 21 is constituted mainly by a slot-shaped seat 28 that narrows, with which the device 17 can be easily presented to the cord 2 such that cord 2 is placed in the seat 28.

The structure of the movement mechanism 22 it is better visible in the schematic presentation of figures 6, 8, 10, 12 and 16, and consists mainly of pressure means 29 to drive the aforementioned supports 3 from the position open of figure 2 to the closed position of figure 4, and by fastening means 30 which allow to keep against the cord 2 a bracket 3 to be driven while being fixed on the cord two.

The pressure means 29 are constituted, in the example represented by a fork 31 suitable for a alternative movement, comprising branches 32-33 that move in the course of alternative displacement, to either side of the aforementioned seat 28.

The fastening means 30 are constituted by a punch 34 that travels together with the means of pressure 29, more specifically with fork 31, but which can sink under pressure in relation to the latter in opposition to a elastic force For this purpose, the punch 34 is fixed by of a rod 35 or sliding analogs in the base element 36 of the fork 31 and a pressure spring is applied between the punch 34 and base element 36. The outermost position of the punch 34 is determined by a stop 38. The punch 34 moves precisely in the extension of the seat 28 and is mobile between a position A on the outside of seat 28 and position B on the seat height 28.

In addition, the device 17 also comprises support means 39 which, according to the invention, are made preferably in such a way that they offer at least two points of support 40 and 41 that are arranged apart from each other, but specifically one above the other, and in such a way that the displacement mechanism 22, more specifically the means of clamping 30, are active between the two support points 40 and 41, as It will be explained in more detail later. These means of support 39 they consist of elements 42-43 that are able to move between a position such as the one that has represented in figure 6 and a position such as that which has been depicted in figure 8, but which are located at levels respectively lower and higher than the punch previously cited 34. In the embodiment shown, elements 42 and 43 are formed by the branches of a fork 44 which is capable to pivot about an axis 45.

Both the movement mechanism 22 and the support means 39 and the feeding mechanism 23 described previously they are dragged, as represented preferably by means of a common drag element, in this case an electric motor 36.

As depicted in Figure 6, this engine 46 is provided with a cam disc 47 that drives the fork movement 44. For this purpose, fork 44 is equipped with a cam arm 48 which is pressed by means of a spring 49 against the surface of cam 50.

The fork movement 31 is obtained because it is coupled through a rod 51 with the cam disc 47 such that this stem 51, so together with cam disc 47, it acts as a mechanism for cams

The feeding mechanism mentioned above 23 is constituted, as shown in figures 5 and 18 a 20, for a drag element 53 with alternative movement, but specifically suitable to swing from top to bottom and vice versa, around an axis 52; this element, when scrolling in a first sense R1, drag step by step to the supports 3 housed in stand 19 and present them one by one at displacement mechanism 22 and in another sense R2, is capable of move freely along the supports 3. For this purpose, the feeding mechanism 23 is equipped with hooks drag 54 which, during displacement in the direction R2, is freely move above the supports 3 and on the other direction R1, the supports 3 are forced to move with them. These drag hooks 54 are rotatable around shafts 55 and are pushed by elastic elements 56 such as small springs towards a corresponding stop 57.

In addition, the feeding mechanism 23 is also preferably equipped with interlocking hooks 58 which they act so that the brackets 3 present in the backup bracket 19 be able to scroll exclusively down.

As already indicated, the mechanism of power supply 23 is also activated by means of the electric motor 46. For this purpose, the drag element 53 is provided with one or several cam followers 59 cooperating with one or more guides 60 cam-shaped, in this case two guides that are fixed respectively on either side of the fork 31.

In addition, device 17 is equipped with means for activating the drag element, which start from engine 46, as well as means that cause the engine 46 to put on new out of circuit when a cycle of job. In the example shown, these means are constituted respectively by an electric push-button 61 for starting the engine 46 and for an interrupt contact 62 which, in the position of figure 6, for example cooperates with the pin 63 of rod 51, which interrupts the feeding of the current to the electric motor 46. By means of the push button 61 undergoes bridging electric.

It is clear that it will also be planned A power supply This power supply can be consisting of batteries that are properly inserted into the housing 64 of device 17 or better still for a connection by middle of a cord 65 with a battery that is ported for example by the user of the device.

It should be noted that device 17 has been preferably made in the form of a handheld device equipped with a handle 66 that allows its operation with the help of a single hand, so that if necessary, the user retains the free hand to hold cord 2 in a more or less extensive state in the desired orientation and / or to hold the floor 1.

The operation of the device 17 has been explained below with reference to figures 6 to 20.

As depicted in Figures 6 and 7, the device 17 is presented first with seat 28 against the cord 2, so that the latter is arranged in the part lower seat 28.

When pressed next on the push button 61, interrupt contact 62 is bypassed and engine 26 is put into service. Because the spike 63 interrupt contact 62 moves away by rotation, the interruption is nonexistent and the electric motor 46 continues running until cam disc 47 has completed a lap complete and, until the spike 63 sinks again the contact of interruption 62.

Because the engine 46 enters service, the Cam disc 46 begins to rotate. It is evident that between the engine 46 v cam disc 47 is present a transmission not represented, so that the cam disc 47 rotates at a speed of relatively small rotation.

During the rotation of the cam disc 47, the handle 34 moves toward the front jointly with the fork 31. so that the support 3 presented must separating by pressure from the other supports 3 tearing the parts of subjects 27. As shown in Figures 8 and 9, in this case is forced inwards against the force exerted by the spring 49, so that they are positioned behind the cord.

Because the punch 34 is subjected to a further displacement towards the anterior part together with the fork 31, the corresponding support 3 is pushed towards the seat 28, so that, as shown in the figure 10, the cord 2 is pressed by means of the holder 3 against the elements 42 and 43, under the influence of punch 34.

At a later stage, as depicted in Figures 12 and 13, the cord 3 is subjected, if necessary, to a slight supplementary deformation, which nevertheless prevents further displacement of the punch 34. The fork 31 continues its movement so that, on the one hand, the pressure spring 37 is tensioned and, on the other hand, branches 32-33 enter contact with elements 13-14. Thanks to the force of pressure exerted by the spring 37, it is guaranteed that the support 3 with the clamping part 6 remain in permanent contact with the cord 2. Branches 32-33 make the elements 13 and 14 rock each other.

In figures 14 and 15 it can be clearly seen that the position of the device 17 in relation to the direction of the cord 2 has no influence on the positioning of the support 3, relative to the cord 2, since the support points 40 and 41 make the cord 2 extend between these support points 40 and 41 always transversely in relation to movement made by punch 34.

Finally, elements 13 and 14 under pressure of tools 32 and 33, as shown in the figures 16 and 17, swing completely with each other, so that the parts closure 15 and 16 are subject to reciprocal engagement. In the case considered the tightening part 6 is lowered so that the cord 2 is imprisoned therein; in other terms, the bracket 3 is firmly attached to cord 2.

In the course of these operations, the stem 5 is maintained because it is surrounded by elements 13 and 14.

During further rotation of the cam disc 47, elements 42 and 43 leave the seat 28 and the device 17 can move away again from the cord 2. The fork 31 moves again to take the position indicated in figure 6.

In the course of the cycle above described, the drag element 53 also cycles as It has been represented, respectively, in Figures 18 to 22. In the movement of the fork 31 towards the part above, the drag element 53 is subjected to a tilting upwards by contact with guides 60. In the course of is tilted up, interlocking hooks 58 prevent that the supports 3, present in the reserve holder 19, are dragged by friction. Drag hooks 54 tilt as shown in figure 19 around axes 67 towards down and move along the brackets 3. In the position higher, as shown in figure 20, the hooks of drag 54 are placed back behind the supports 3, but in a higher position so that, when the brackets 3 they swing back down, they all extend a place. In the course of this cycle, support 3, located below is downloaded as indicated above and applied to the cord 2, so that, during the return movement towards below the drag element 53, the next support 3 in the lowest position reaches the waiting position for one cycle next.

Preferably, the rotation movement has place under the influence of a spring not shown or of any other way.

It is evident that different variants are possible both in terms of the device and in what refers to the supports.

In this context, it should be noted that the notion Backup support must be interpreted in a very meaningful way large. Through the expression `` backup support '' you must understand, according to the invention, any form of mechanism that allow one-to-one support to be presented to the displacement mechanism regardless of knowing if the supports are found in a grouping space or are fed into the device Systematic way from a band.

In the case where the brackets are fixed each other in the form of a band, this feature can be realized both by fixing it parallel to each other and by union with each other in the longitudinal direction as if it were in the form of a ribbon.

The notion of support must also be interpreted in its broad sense. In a particular embodiment, these `` supports '' can be constituted, initially, by a simple material tape that is cut longitudinally in the device and that is machined to obtain a loop-shaped support that fixed on cord 2 in one way or another.

It will also be noted that the tightening part 6 of support 3 must not necessarily be kept closed by the closing parts 15-16 of the fixing part 7 for floor 1. Thus, for example, the tightening part 6 for the cord 2 and the fixing part 7 for the floor 1 can have separate closing mechanisms. An example in this regard is has been schematically represented in figure 21 in which the support 3 is fixed on the cord 2 by means of a part of tighten 6 with a locking mechanism 68 while the part of fixing 7 is equipped with its own closing mechanism 69.

The invention is not limited to supports 3 that be foldable. In figure 22 it has been represented, so schematically, a support 3 according to the invention that is constituted by a folded element in loop 70 that is fixed to the cord 2 in the proximity of its two extremities. For this purpose. the aforementioned limbs are provided with weatherstrips 71 and 72 and the Cord 2 forms a loop around the aforementioned limbs. The loop-shaped part 73 of the cord 2 is joined in the proximities of its base by means of a connecting element 74 such as a bracket or the like such that element 70 is prevented from leaving the loop-shaped part 73 by means of the aforementioned weatherstrips 71, 72. When a support 3 of this type with the element 70 around the stem 5 of the floor 1, se, an effect similar to that of figure 1 is obtained. It is evident that, in this case also the feeding of the elements 70 can have place automatically from a device, and must then be equipped with this device with means that hold the cord 2 and forming a loop-shaped part 73 therein, as well as means leading to the connecting element 74.

The present invention is not limited in mode. some to the embodiments described by way of example and represented in the figures; a procedure, a device and supports of this type can be made according to different variants without leaving the scope of the invention.
