Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tying tool for tying a plant cultivation net such as a vine cultivation net to a support.

[Conventional technology]

Nets for plant cultivation are stretched between poles stuck into the ground, and conventionally the ends of the nets were tied to the poles with strings to hold the nets to the poles.

[Problems to be solved by the invention] However, the conventional method using strings was very cumbersome and required a great deal of time and effort when there were many tying points. Also, when removing the net, the string was cut with a cutter, etc.
It was difficult to reuse it.

This invention solves these problems,
To provide a reusable tying tool which can easily tie the end of a net to a support in a short period of time.

[Means for solving problems]

In order to achieve the above object, the binding device of the present invention has a large number of protrusions that are densely provided on the inner surface of the band-shaped wrapping portion that is wrapped around the support, and is crushed by being pressed against the support. and two protrusions each having a glans-shaped bulge at the tip are provided side by side in the extending direction of the protrusion on a protrusion extending from one end of the wrapping part, and the wrapping part The two protrusions can be individually inserted into the protrusion extending from the other end, and two holes smaller than the bulges are arranged side by side in the extending direction of the protrusion. It is made of a certain synthetic resin molded product and has the gist in that the two protrusions are spaced apart from each other by a distance through which a thread of the net can be inserted.

[Effect]

According to the tying tool configured in this way, the winding part is wrapped around the support, the warp at the end of the net is inserted between the two protrusions, and the protrusion is pushed into the hole to form the glans-shaped part. The net is tied to the post by engaging the bulge with the hole. At this time, a large number of raised portions provided on the inner surface of the wrapping portion strongly abut against the support column and are crushed to prevent the binding tool from slipping off. Also, the net is removed from the support by forcibly pulling out the bulge from the hole.

〔Example〕

FIG. 1 shows a binding device 10 according to an embodiment of the present invention.
It shows 0. In the figure, reference numeral 1 denotes a band-shaped winding portion, on the inner surface of which a large number of raised portions 2 are densely provided at predetermined intervals. Symmetrical protrusions 3 and 4 are integrally extended from one end and the other end of the winding portion 1, and one protrusion 3 has two protrusions 5 and 6.
are lined up in the extending direction of the projecting pieces 3 and protruded at intervals through which the threads of the net described later can be inserted,
The other protruding piece 4 is provided with holes 7 and 8 corresponding to the protrusions 5 and 6. Illustrated example binding device 1
00, the winding part 1 in its natural state has a semicircular arc shape, and the protrusions 3 and 4 extend to the outside of the winding part 1, but the shape of the winding part 1 and the protrusion 3 , 4 is not limited to this. For example, a projecting piece may be provided on a winding portion that is straight in its natural state and extending in the longitudinal direction of the winding portion, or a projecting piece may be provided on a winding portion that is C-shaped in its natural state and extending outward.

As shown in FIGS. 2 to 4, the protrusion 6 has an upper part 9a and a lower part 9b of a shaft part 9 protruding from the protrusion piece 3, and has a glans-shaped bulge at the tip thereof. It has 10. As is clear from FIG. 4, the diameter of the bulge 10 is the same as the width of the shaft 9. The same applies to the other protrusions 5, and 11 is the shaft portion of the protrusion 5. As shown in FIGS. 5 and 6, a circular chamfer 12 is formed around the hole 8. As shown in FIGS. In addition, in the illustrated example, the hole 8 is rectangular, and its vertical width h
is slightly larger than the vertical width H (see Fig. 3) of the shaft portion 9, and its width l is set to be equal to or slightly smaller than the horizontal width L (see Fig. 4) of the shaft portion 9. . Therefore, for the hole 8, the protrusion 6 is connected to the protrusion 4.
The bulge 10 of the protrusion 6 engages with the hole 8 in the inserted state. Chamfered portions 13 are also formed in the other holes 7. Further, the dimensional relationship between the other holes 7 and the protrusion 5 is similar to the dimensional relationship between the hole 8 and the protrusion 6 described above.

The binding tool 100 described above is made of a flexible synthetic resin molded product such as medium-low pressure polyethylene resin. As shown in FIGS. 2 and 3, the projecting piece 3 has crescent-shaped through holes 14, 14 formed on both sides of the shaft portion 9 of the projection 6. As shown in FIGS. The through holes 14, 14 form a stepped portion 10 of the bulging portion 10 of the protrusion 6.
This is a trace of the core being pulled out to form a.
On both sides of the shaft portion 11 of the other protrusion 5, through holes 15, 15 are formed in the protrusion piece 3, which are marks from which the core was pulled out.

FIG. 7 shows the binding tool 100 in use. In the figure, 200 indicates a support and 300 indicates a net. The binding tool 100 has its winding part 1 wrapped around the support column 200 so that the two protrusions 3 and 4 are facing each other, and as shown in FIG.
4, insert the warp 310 at the end of the net 300 between the two protrusions 5, 6, and insert the warp 310 of the net 300 between the protrusions 5, 6. 4 are pushed into the holes 7 and 8, respectively, by utilizing their flexibility. In this state, the raised portions 2 of the wrapped portion 1 strongly abut against the support 200,
Since it is crushed against the elasticity, the binding tool 100 does not slip off the support 1. Further, for example, the bulging portion 10 of the protrusion 6 is engaged with the hole 8 via the stepped portion 10a, as shown in FIG. 9, and is prevented from coming off. The same applies to the other protrusions 5. Therefore, the winding portion 1 is wound around the support 200 and the protrusion 5,
6 into the holes 7 and 8, the net 300 is tied to the support column 200.

When removing the net 300 from the support 200, pull the protrusions 3 and 4 in the direction of separation, and
6 can be forcibly pulled out from the holes 7 and 8.

[Effect of idea]

As described above, according to the tying device of the present invention, it is possible to easily and reliably tie a net to a post in a short period of time, it is difficult to cause a situation where the tying device slips off the post while it is tied down, and furthermore, In addition to being able to easily remove the net, it also has the advantage of being reusable.
