Description

[Detailed description of the invention] Industrial application field This invention relates to a sprinkler that uses the pressure of tap water to rotate the nozzle in gardens, farms, etc. to uniformly sprinkle water over the required area. The details relate to the vibration or fall prevention device.

Background of the invention and prior art There has been a demand for sprinklers of this type to be lightweight, compact, and easy to handle. However, when such a lightweight and compact sprinkler is used to spray water with high water pressure, there is a problem in that the sprinkler vibrates violently as the nozzle rotates and may eventually fall over. Of course, reducing the water pressure can prevent the sprinkler from vibrating, but this reduces the area of water spraying and creates the hassle of having to move the sprinkler and repeat the watering.

This invention was made in view of the above-mentioned circumstances, and the object is to provide a sprinkler that is free from vibration or even overturning even under high water pressure.

Means for Solving the Problems In order to achieve the above object, the sprinkler vibration or overturn prevention device according to this invention is characterized in that a plurality of leg members are swingably provided on the base.

In a preferred embodiment of this invention, the leg members are provided so that when the sprinkler is installed on the ground, the legs are splayed outward in a downwardly sloping manner to lift the base from the ground.

Embodiments Next, embodiments of this invention will be specifically described based on the drawings.

Embodiment 1 In Figures 1 and 2, 1 is a sprinkler used in gardens, farms, etc., which consists of a base 2, a sprinkler nozzle 3, and a hose connection port 4.
The main focus is Reference numerals 5 denote leg members provided at three apexes of the base 2, which is approximately triangular in plan view, each having a curled portion 5a at each base end and a serrated claw portion 5b at each tip. . 6 is base 2
These horizontal pins are provided on the lower surface of the base 2 at the three apex portions thereof, and these pins penetrate the base 2 at both ends, and each has a head 6a at the end protruding from the base 2 to prevent it from coming off. The three pins 6 are passed through each curled portion 5a of the leg member 5, respectively. In this way, the three leg members 5 are swingably attached to the base 2.

Note that both ends of the pin 6 may be held in the recess 2a of the base 2, as shown in FIG. 3, without passing through the base 2.

As shown in FIG. 1, after the sprinkler 1 is placed at a desired location such as in a garden, the three leg members 5 are opened and placed slightly closer to the distal end from the base pivot point of each leg member 5. It abuts against the lower edge of the base 2 and is prevented from rotating. In this way, all three leg members 5 are spread outward in a downwardly sloping manner, thereby lifting the base 2 from the ground. In this state, the claw portions 5b of the leg members 5 bite into the ground and prevent the sprinkler 1 from vibrating.

Embodiment 2 In FIG. 4, the base 12 has a substantially quadrilateral shape when viewed from above, and leg members 15 are swingably provided on the lower surface of each of the four vertices of the base 12. These leg members 15 are also stopped from rotating by hitting the lower edge of the base 12 at a position slightly closer to the distal end of the base end pivoting portion, and are opened in a downwardly sloping manner to lift the base 12 from the ground. ing.

Since the other configurations are the same as those of the first embodiment, the same reference numerals as those of the first embodiment are given to the drawings, and explanations thereof will be omitted.

Embodiment 3 In FIG. 5, the base 22 is in the shape of an inverted bowl,
Three leg members 25 are also swingably provided on the lower surface of the edge of the base 22. These leg members 25 are also stopped from rotating by hitting the lower edge of the base 22 at a position slightly closer to the distal end from the base end pivoting portion, and are opened in a downwardly sloping manner to lift the base 22 from the ground. ing.

Since the other configurations are the same as those of the first embodiment, the same reference numerals as those of the first embodiment are given to the drawings, and explanations thereof will be omitted.

Effects of the invention As described above, according to this invention, since the plurality of leg members 5, 15, 25 of the base 2 are swingably provided, the leg members 5, 15, 25 can be moved at desired positions.
The sprinkler 1 can be placed on the ground with good stability by opening the legs of the sprinkler 25 in an outwardly downwardly sloping manner. Therefore, even if the sprinkler 1 is loaded with high-pressure water, it is possible to reliably prevent the sprinkler 1 from vibrating or even falling over as the nozzle rotates.
