Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an antifreeze device that is most suitable for preventing freezing of greens in golf courses, for example.

(Prior Art) When the green of a golf course freezes, it interferes with play, so during the winter, the green is covered with a seat cover at night.

(Problems that the present invention aims to solve) However, simply covering the seat cover cannot be expected to have a sufficient heat retention effect, and since there is no air flow inside the seat cover, its antifreeze function can hardly be demonstrated. .

Also, if the green freezes with the seat cover on, the grass on the green will stick to the seat cover, but if you forcefully remove the seat cover in this state, the grass will peel off as well, so in this case had the problem of damaging the green itself.

The object of this invention is to provide a device that completely prevents freezing by supplying air to the inside of a seat cover placed over a target ground.

(Means for Solving the Problem) In order to achieve the above object, this invention provides a holding device around the seat cover, covers the desired ground with the seat cover, and surrounds the seat cover with the holding device. While pressing the seat cover, a blowing means is provided for supplying air to the inside of the seat cover, and the air is released from around the seat cover while inflating the seat cover with the wind pressure of the blowing means.

(Operation of the present invention) As described above, press the seat cover around the seat cover with a presser, place the seat cover on the target ground,
When air is supplied to the inside of this seat cover,
The air is trapped inside the seat cover to some extent, and the air gradually escapes from the surrounding area.

Therefore, by continuously supplying air from the blowing means, the seat cover is always maintained in an appropriately inflated state, and the air therein is allowed to flow.

(Effects of the present invention) According to the device of this invention, air is continuously supplied to the inside of the seat cover to inflate it, and air is released little by little from around the seat cover to inflate the inside of the seat cover. Since the flow of air is generated, water in the ground is released by the flow of air, completely preventing freezing of the area covered by the seat cover.

(Embodiment of the present invention) A plurality of mounting bands 2 are provided around the back surface of the seat cover 1 at predetermined intervals. A removable hook 2a is provided.

A flexible hose 3 is placed around the back surface of the seat cover 1 thus constructed, and the hose 3 is fixed to the seat cover 1 with the attachment band 2.

Both ends of the hose 3 are closed with a male plug 4 and a female plug 5, and these plugs 4 and 5 are connected to make the hose 3 endless. Further, this hose 3 is filled with antifreeze to maintain a constant weight and function as a holding device of this invention.

Further, a supply hose 7 of the air blowing means 6 is opened on the back surface of the seat cover 1 so that air from the air blowing means 6 is supplied to the back surface of the seat cover 1.

Note that if the air supplied from the supply hose 7 directly hits the lawn, it may dry out the lawn, so when the seat cover 1 is inflated as shown in FIG. It is preferable to specify the mounting position of the supply hose 7 so that the air is supplied to the air.

Then, as shown in FIG. 3, the seat cover 1 is placed over the destination and the hose 3 is grounded.

When air is continuously supplied from the air blower 6 in this state, the seat cover 1 remains in contact with the hose 3, so the seat cover 1 is moved to the third position.
It will expand as shown in the diagram. At the same time, the air inside the seat cover 1 escapes little by little from between the hose 3 and the ground, so that the seat cover 1 maintains a constant inflated state and generates a flow of air therein.

When air flows inside the inflated seat cover as described above, water in the ground is released by the air, so that the portion covered with the seat cover 1 can be reliably prevented from freezing.

If the seat cover 1 does not inflate, the air will not be distributed throughout the seat, and the areas to which air is not supplied may freeze. However, in this embodiment, air is allowed to escape from around the seat cover 1, so air flow can be generated in all parts of the seat cover, and the entire interior of the seat cover can be prevented from freezing. It can be prevented.

In addition, since the hose 3 has flexibility as described above, for example, even if there are undulations at the destination, the hose 3 will ground along the undulations. Since the hose 3 is always maintained in a grounded state, it is possible to prevent the seat cover 1 from becoming inflated due to an extremely wide gap between the periphery of the seat cover and the ground and a large amount of air escaping from there.

Moreover, since this hose 3 is filled with antifreeze, even when the hose 3 is in the grounded state,
It can prevent it from freezing.

However, the hose 3 may be filled with normal water without putting antifreeze in it, but if antifreeze is put in it, there is an advantage that the hose 3 will not freeze.

In addition, the presser in this invention means that when air is supplied to the back side of the seat cover 1, an appropriate amount of air escapes from the surrounding area to maintain the seat cover 1 in an inflated state, and also to hold the seat cover 1 in an inflated state when the wind blows. The hose is not limited to this embodiment, as long as it fulfills the function of preventing the hose from flying off.

However, if you use a hose, you can ground it along the undulations of the ground as described above, and once the liquid inside it is drained,
The overall weight can be reduced, which is advantageous when storing the device.

In addition, if you are in a windy area and cannot hold down the seat cover 1 with just the holding device such as the hose mentioned above,
A stopper piece 8 may be provided at a predetermined location on the seat cover 1, and a stake or the like may be driven into a hole 9 formed in the stopper piece 8.
