DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention has the flexibility of forming a myriad of small holes on a surface suitable for use as a watering device for crops, trees, lawns, and the like, or as a device for spraying liquid fertilizer. The present invention relates to a fastener for holding a watering tube.

[0002]

2. Description of the Related Art A flexible plastic-like irrigation tube, such as vinyl, having a myriad of small holes on its surface for spraying water or liquid fertilizer onto fields, hydroponic crops, trees, lawns, etc. Often used. This tube is sometimes left just as it should be, such as when spraying on the lawn or playground, but it is generally located along crops and trees, where the stomatal holes are fixed and watering is directed in a given direction. It is installed to face. In any case, such irrigation tubes have conventionally been simply left unattended or simply placed alongside crops and trees, and are not fixed. They tended to jump out of a predetermined place due to the momentum of the water, or to reverse and change the watering direction.

[0003] In order to fix the irrigation tube, it may be hooked on a wire or tied with a wire or a string.
A fixed object such as a fence or a support is required to attach a wire or string, such as a fence, to the vicinity, and simply hooking on the wire lacks the certainty of fixing. It is difficult to tie the irrigating tube in a flat state so as not to inhibit the bulging.In addition, if there is not enough room for the irrigating tube to swell in the tied state, when the irrigating tube swells at the time of passing water, the part is squeezed and pressure is applied. If the loss is large and the margin is sufficient, the irrigation tube is likely to be inverted.

As described above, since the above-mentioned irrigation tube has flexibility and is flat when water is not passed,
Although it is easy to lay, remove and store, it swells when water is passed and narrows when water is not passed, making it difficult to firmly fix the irrigation tube so that it does not turn over when water is passed or stopped. . To solve this problem,
Japanese Utility Model Publication No. 9-38135 and Japanese Utility Model Publication No. 3-41833 disclose a jig that presses and fixes an irrigation tube from both sides with a pair of flexible tongues facing each other.
Japanese Utility Model Publication No. 4-4518 proposes a jig or the like for pressing and fixing an irrigation tube with a flexible band.

[0005]

According to the jig as described above, the watering tube can be firmly fixed so that the watering tube does not turn over even when the water supply or the water supply is stopped. There is room for improvement. An object of the present invention is to provide a durable watering tube fixing jig that can be used repeatedly over a long period of time.

[0006]

Therefore, the fixing jig of the present invention has a circular, elliptical, polygonal, or other arbitrary annular shape, and has a maximum circular diameter that is smaller than the width of the flattened irrigation tube. The irrigation tube is also small, and the recessed portion where the side end of the flattened and irrigated tube is fitted is formed at the opposing portion, and the interval between both recesses is larger than the width of the flattened irrigation tube. Things.

FIG. 1 shows an example of this, where the major axis is c.
It has an elliptical shape smaller than the width b of the irrigation tube 1 which is narrowed and flattened, and has concave portions 2 formed at both ends of the long diameter portion, and the interval a between the concave portions is larger than the width b of the flat irrigation tube 1. It is made of a plastic or metal jig 3 with a>b> c, and the minor diameter d is approximately the same as the diameter y of the swollen irrigation tube 1 at the time of water flow, as shown in FIG. By setting y ≧ d, the irrigation tube swelled at the time of watering is securely fixed, so that the watering direction is constant without the tube being inverted.

According to the jig of the present invention, the tube is not pressed down and fixed by the elastic force, and does not undergo elastic deformation. When using the jig of the present invention, for example, as shown in FIG. 3, a leg 4 is attached to the jig 3, and the leg 4 is fixed by hitting it into the soil, or is inserted horizontally or vertically into a fixed pipe. Or tied to a fixed object such as a pile, or
As shown in FIG. 5, a screw 8 is fastened to a supporting member 6 which constitutes a house, a pillar 6 which is fixed by being driven into the soil, and a pipe or a pile which is fixed by being inserted into a soil. Alternatively, use trees, fences,
It can be used by being tied to a support or the like or suspended.

When attaching the irrigation tube using the above-mentioned jig, the irrigation tube is attached by passing a flat irrigation tube when water is not flowing in a state as shown in FIG. 1, but in this case, from the end of the tube. It must be passed through and cannot be attached to or detached from the laid tube.
This problem is solved by allowing the jig to be opened and closed. For opening and closing, a hinge may be provided so as to be able to open and close, but as shown in FIG.
In particular, when the former hinge is provided, it is desired to provide a lock means so that the hinge can be fixed in a closed state. FIG. 5 exemplifies a locking means comprising a locking portion 11 and a hook 12 forcibly locked by being pushed into the locking portion. In this case, when the hook 12 is to be detached from the locking portion 11, the hook 13 is pushed up and the hook 12 is pryed open to be detached.

When the jig is fixed with the tube lifted, it is preferable that the tube is widened and the tube is fixed widely so as not to bite into the tube and bend the tube. The watering hole is closed and watering is hindered. To solve this problem,
It is desirable to make holes for watering on at least one side. As shown in FIG. 5, when the hole 14 is formed on one side of the jig, it is necessary to mount the tube with the watering hole facing the hole 14, whereas the hole is formed on both sides. If so, it can be mounted in any orientation.

[0011]

6 shows a fixing jig 9 shown in FIG.
And a plastic jig integrally formed by projecting a plate-shaped mounting portion 5 on the side surface of the locking portion 11 side.
It is adapted to be connected to a screw which is screwed through the clasp 7 and the mounting hole 15 as shown in FIG.

Next, when the tube 1 is fixed by using a jig 16 with legs shown in FIG. 7, the tube 1 is fixed by using a jig 17 with legs having no recess as shown in FIG. As shown in FIG. 9 and FIG. 9, a comparative experiment was performed for each of the cases where the tube 1 was fixed using a jig 18 in which the upper surface of the jig 3 shown in FIG. 7 was opened. In the jig shown, the tube 1 did not turn over even when it was subjected to wind when water was not flowing, whereas the jig 16 shown in FIG. Further, when watering was repeated, the watering direction was stable in the jig 3 shown in FIG. 7, whereas in the jig 16 shown in FIG. 8, the watering direction changed every time watering was repeated, as shown in FIG. 9. When the watering was completed in the jig 17, the tube 1 came off the concave portion 2, and the tube could not be fixed.

[0013]

The present invention is configured as described above and has the following effects. According to the jigs of the first and second aspects, the watering tube does not reverse even if it receives wind when water is not passed, and the watering direction is stable. In addition, the tube is not fixed by the elastic force. It does not deform, and therefore has durability and can withstand long-term use.

In the jig according to the third aspect, the irrigation tube during the passage of water is securely fixed, and the direction of watering is constant. In the jig according to the fourth aspect, the leg can be attached by driving the leg into the soil, by inserting the leg into a pipe, or by binding to a fixed object such as a pile.

In the jig according to the fifth aspect, the mounting portion can be connected to a metal fitting or the like, tied or hung. According to the jig of the sixth aspect, the jig can be attached to an arbitrary position and fixed to or detached from the irrigation tube to be laid. In the jig according to claim 7, since the jig does not deform at the time of opening and closing,
Since the jig according to the eighth aspect has durability and can be integrally formed as a whole, it is easy to manufacture, has a simple structure, and can be manufactured at low cost.

According to the ninth aspect of the present invention, if the locking means is provided, the tube is fixed in a closed state, without careless opening, and the tube is securely fixed. Claim 10
In the described jig, water can be sprinkled through the watering hole, and the watering function can be prevented from being impaired by the jig closing the hole of the irrigation tube.
