FR2887398A1 - Vine shoot fixing device for e.g. trellis cultivation, has meanders creating tightening zones to lock device on retaining wire, where device is fabricated by injecting biodegradable, biofragmentable or degradable plastic material in mold - Google Patents

Abstract

The device has meanders (1, 2) connected by an external part (6) and creating tightening zones for locking the device on a retaining wire, where the device is fabricated by injecting a biodegradable, biofragmentable or degradable plastic material in a mold. A flexible central part (5) retains a vine shoot. The part (6) has a manipulating zone (7) to manipulate the part (6) and includes indentations (8) to integrate the wire to the device.

Description

The present invention relates to a fastener for holding in place the

  stem of a plant on a stretched wire called guard wire or holding wire.

  In crops such as vines, plantations are planted online and at regular intervals. To orient the newly cut twigs, stakes connected by wires are placed to form a row of vines. The branches or shoot are fixed on these stretched threads.

  The systems used so far for the attachment of vines consist of small diameter wire wrapped in paper or plastic placed manually or using electrically operated portable machine or by degradable plastic fasteners. or not. All these systems have the disadvantage of not fixing vigorously the shoot on the holding wire. As the days go by, the ligation of the small iron wires around the branch can be relaxed, or even if the ligature is too strong, strangle the branch. As for the plastic fastener, it manages to move along the wire and does not exactly fulfill its function.

  The object of the present invention aims to overcome all these disadvantages through a device forming a fastener integrally retained to the holding wire by creating zones forming a prestressing of the material on the wire.

  The invention therefore relates to a fixing attachment of a shoot on a stretched wire having self-locking zones to prevent the wandering of the fastener along the holding wire.

  The device according to the invention is molded thermoplastic, by injecting material into a mold, flat, and on the same plane. It is conceivable, for economic reasons, to perform the manufacture of the fasteners by extrusion of material giving fastener bars which will then be cut to give individual fasteners. The fasteners comprise, at each end, meanders to create throttling zones favoring the locking of the fastener on the holding wire. It has a central part holding the shoot in its middle firmly to hold it along the wire and having a certain elasticity to let it grow without injuring it and without strangling it. The other part connecting the two meanders makes it possible to maintain the whole and is used for its manipulation. It has a meander not closed for an entry of the horizontal branch by sliding it along the wire or closed for a vertical entry of the vine shoot.

  The device according to the invention is made of degradable plastic material, biodegradable or biofragmentable flat section to promote this degradation by playing with the thickness of the fastener to optimize the phenomenon of degradation related to light, but it can imagine all kinds of sections and create, for example, visible or invisible breakthroughs to achieve its destruction even with the use of non-degradable material.

  The device according to the invention thus characterized is of a size which may vary according to the section of the oath to be imprisoned of a vine with high vegetation and - 3 for these reasons it is not possible to give quotations as well as an exact shape of the meanders that can be formed with more or less amplitude to respect the diameter of the holding wire or even have one or more notches to further secure the holding wire.

  The device according to the invention is manufactured in a mold with multiple individual borrowings and one can easily consider linking them together to form clusters to win over the time of their apprehension.

  Other features and advantages will become apparent from the following description given solely by way of non-limiting example and with reference to the accompanying drawings in which: FIG. 1 is an elevational view of an embodiment of the fastener according to the invention fixed on the holding wire with entry of the shoot along the wire.

  Figure 2 is an elevational view of the fastener with entry of the shoot vertically and perpendicular to the holding wire.

  The fastener consists of the following: The meanders (1 & 2) formed at each end by curvatures of the material (3 & 4) crush the holding wire through their manufacture on the same plane and create a self-locking point on the holding wire. The central portion (5) flexible adapts to the size of the oath it receives.

  The outer portion (6) connects the two meanders and has an area for handling (7) and notches (8) for securing the wire and the fastener. - 4 -

  The fastening mode thus formed according to the embodiment described above is simple and effective since it suffices to present the shoot with regard to the opening and forcing it into force according to the embodiment of FIG. 2 from the bottom to the top. and for the embodiment according to Figure 1, put the wire at the bottom of the meander (2) and rotate the clip on itself. At this moment, since the branch is larger than the receiving zone (9), the branch (5) moves backwards and the meander portion (2 & 1) crushes the holding wire (10) and in the example of FIG. external branch (6) just fix the meander (1) solidarisant all by locking the fastener.

  The device according to the invention is of simple and effective use and when it is clustered, it can save a huge time compared to all currently used systems and moreover, thanks to its ergonomics, it s' suitable for many other tasks in the field of plant cultivation.
