Description

[Detailed description of the invention] Industrial application field This invention is a flexible device with numerous small holes on its surface suitable for use as an irrigation device for agricultural crops, trees, lawns, etc. or as a device for dispersing liquid fertilizer. The present invention relates to a fastening device for holding a watering tube with a water spray tube.

Conventional technology A flexible plastic watering tube like vinyl with numerous small holes drilled on its surface is used to spray water and liquid fertilizer onto fields, hydroponic crops, trees, lawns, etc. There are many things to do. Sometimes these tubes are simply left in place, such as when watering lawns or playgrounds, but generally they are placed along crops or trees, with holes aligned and the watering direction directed in a predetermined direction. installed to face. In any case, in the past, these watering tubes were simply left alone or placed along crops or trees, but were not fixed, so when water was not flowing, they were blown away by the wind, etc. The force of the water during watering tends to cause it to splatter and come off the designated spot, or to turn around and change the direction of watering.

To secure the watering tube, it is sometimes hung on a wire or tied with wire or string.
A fixed object, such as a shelf or a support, is needed nearby to attach the wire or string, and simply hooking it to a wire lacks the certainty of fixing it, and tying it up with wire or string is also better suited to watering tubes. In particular, with the type of watering tube that is formed by fusing both sides of a pair of thin long plastic tapes, it is difficult to tie the watering tube in a flat state when water is not flowing so as not to inhibit the swelling of the watering tube. ,
In addition, if the watering tube does not have much room to expand in the tied state, when it expands during water flow, the portion will become constricted and pressure loss will increase, and if there is sufficient room, the watering tube will easily flip over.

Problems to be Solved by the Invention In order to solve the above-mentioned problems, Utility Application No. 61-20812 proposes a fixing device that can securely fix a flexible watering tube. . As shown in FIG. 5, this fastening tool consists of a frame 2 having a nail-shaped cross section and an insertion portion 1, and a flat groove 4 into which a tube 3 folded into a flat state is fitted in the center of the head. along with forming a flat groove 4
Head pins are provided on both sides of the head pins to face each other, and a plastic elastic band 6 is mounted on the head pins by force-fitting the pins 5 into the fitting holes 7. Since the watering tube is held between the stand 2 and the band 6, it will not be blown away by the wind or splashed by the force of water when water is flowing, and the band is It has the advantage of being able to support the watering tube in a relatively stable state because it has elasticity and expands and contracts according to the expansion and contraction of the watering tube and holds the watering tube in a relatively stable state. Even if the tube width of such a fastener is widened, it is limited to a size that can fit between the pins protruding from the upper surface of the head, and there are restrictions on the tube width to which it can be attached.

The object of the present invention is to provide a fastening device to which a watering tube having a wider width than the above-mentioned fastening device can be attached.

Means for Solving the Problems According to the present invention, a removable locking means such as a pin is provided on the side or lower part of the head. That is, as shown in FIG. 1, the present invention has a pedestal 13 equipped with an insertion section 11 that is inserted into underground or fixed pipes, or a mounting section that is attached to a shelf, support, or other fixed object. It consists of a band 16 which is removably fixed to the side or lower part of the pedestal 13 by means of a locking means, and holds the watering tube between the pedestal 13 and the pedestal 13.

Here, the locking means may be of any type as long as it can removably lock the band to the pedestal. A typical example is a concave part, cut groove, etc. provided on either the stand or the band, and a convex part, pin, etc. provided on the other side, which is forcibly fitted into the recess, cut groove, etc. in a removable manner. Things can be mentioned.

The band may be fastened to the side or bottom of the pedestal on both sides by locking means,
It may be bendably connected to the frame at one end and stopped at the other end by a locking means,
In any case, it is preferably made of a stretchable material so that it can expand and contract according to the swelling of the watering tube, and can hold the tube firmly.

The watering tube is made of rubber or plastic, or is formed by fusing the edges of a pair of front and back plastic tapes, and is of the type that constricts and becomes flat when water is not flowing through it.

The watering tube is held between the stand and the band, but in order to hold it more securely, one or more protrusions are provided on either or both of the stand and the band. It is desirable to support the watering tube with This is because the protrusions bite into the watering tube and are supported in a stable state. In particular, if the pair of protrusions are arranged at an interval narrower than the diameter of the swollen watering tube, or if a groove with a groove width narrower than the diameter of the swollen watering tube is formed in either the stand or the band, preferably both. Both protrusions or groove edges dig into the watering tube, and the swelling of the watering tube can be absorbed between the protrusions or within the concave groove, reducing the amount of deformation of the band, thus reducing fatigue. The effect of deterioration is reduced, the resilience is maintained, and it becomes possible to withstand long-term use.

Embodiment The figure shows a fixing device used to fix a watering tube formed by fusing both sides of a pair of long and thin plastic tapes. Frame 1 with nail-shaped cross section with holes in place
3 has headed pins 15 drilled on both sides of the lower side of the head 14, and an elastic tape-shaped band 16 made of plastic stretched over the head 14 into the notches formed at both ends. It can be stopped by inserting the headed pin 15.

To fix the watering tube with this fixing tool, first place the watering tube 19 on the head 14, wrap the band 16, and fix both ends with the head pins 15 to attach it to the watering tube 19. Next, drive the insertion part 11 into the ground as shown in FIG. 1, or insert it into a pipe-shaped stake 18 as shown in FIG. This is done by attaching it to the Figure 1 shows the state when water is flowing, and Figure 2 shows the state when water is not flowing. The watering tube may be attached to the anchor after the anchor is inserted into the ground or stake.

In the embodiment shown in FIG. 4, a headed pin 20 is provided protruding from the side of a pedestal portion 21, and a semicircular groove 22 is provided in the head 21, the groove width of which is narrower than the diameter of the tube when water is flowing.
At the same time, a groove 24 corresponding to the groove 22 is also formed in the band 23. In order to form the groove 24, the band 23 is formed with a thick wall or is made of several layers as shown in the figure. Formed into a laminate. According to this embodiment, when water is passed through, the watering tube 19 is guided by the groove portion and swells, so it easily swells.
The amount of deformation of the band is also reduced, making it durable for long-term use, and pressure loss during water flow is also relatively small. Moreover, as shown in the figure, the watering tube 19 is supported in a relatively stable state by four-point support by both the edges of the pedestal and the groove ends of the band, and each point is inflated with the tube biting into the tube, making it difficult to rotate. Therefore, the position of the small water sprinkling hole (not shown) formed in the tube swells uniformly, and the direction of water spraying becomes constant.

Effects of the invention As described above, the fastening device of the present invention is such that the band is fixed to the side or bottom of the pedestal part by the fastening means, and is similar to the pin of the conventional fastening device. Furthermore, since there is no obstacle to attaching a watering tube to the upper part of the head, a larger watering tube can be attached.
