Abstract

To provide an anti-freezing sheet that solves the problem that an outdoor water supply pipe freezes and water or hot water does not flow, and that can be easily installed by ordinary people who do not have specialized knowledge. A material 1 that is waterproof, transparent, allows sunlight to pass through, and has a waterproof effect as a surface layer, and a material 2 that has a cold-proof effect like a blanket as a back layer and an inner layer, and freeze prevention is realized. . The most distinctive feature is that the surface layer is made of a transparent and waterproof material such as vinyl chloride, allowing sunlight to pass through when the sun is out, thereby improving the efficiency of anti-freezing.

Description

TECHNICAL FIELD The present invention relates to an anti-freezing sheet in which a material that is waterproof and allows sunlight to pass through and a material that protects against the cold are layered together.

Anti-freezing sheets for automobiles that also serve as sunshades and anti-freeze sheets exist, but in the case of automobiles, materials such as aluminum are often expected to have a sunshading effect, and the sunshading effect is the opposite of the expected effect of the present invention.

The existing anti-freeze belt for water supply is used by wrapping it around water supply pipes, but there is some concern about anti-freezing.

Existing heat insulation tubes are used by covering them with water supply pipes, etc., but since the pipes often have complicated shapes, straight heat insulation tubes have the disadvantage of being difficult to use.

To enable anyone to easily use even a complicated piping structure.

To solve the problem that a wet blanket freezes after it rains or snows, although covering a water supply pipe with a blanket to prevent freezing is highly effective and does not freeze.

The present invention solves the problem by using a material such as transparent vinyl for the surface layer that is waterproof and allows sunlight to pass through.

The back layer and the inner layer are made of a cold-proof material such as a blanket to prevent the water supply pipe from freezing.

By making the surface layer of transparent vinyl or the like, it exhibits a waterproof effect when it rains or snows, and when the sun is out, it allows sunlight to pass through and prevents the water supply pipe from freezing.

By using a soft material such as a blanket, the anti-freeze sheet can be easily wound and used even in a complicated piping structure.

If the present invention has an elongated structure, it can be easily wrapped around a pipe, and by being able to be cut with scissors or the like, it becomes an easy-to-use anti-freezing sheet.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an embodiment of the present invention in which a surface layer is made of a transparent material with a waterproof effect; 1 is a perspective view of an embodiment of the present invention in which a surface layer is made of a waterproof material; FIG. It is an image diagram of a state that the anti-freezing sheet of the present invention is cut with scissors. It is an image figure which attached the plane-shaped this invention to the water supply pipe, and tied it with a string. It is an image figure which attached the strip|belt-shaped this invention to the water supply pipe, and tied it with a string.

The surface layer is made of a material that is waterproof and allows sunlight to pass through, and the back layer and inner layer are made of a material that protects against the cold. It absorbs sunlight and prevents freezing.

In Fig. 1, a transparent material 1 such as vinyl chloride that is waterproof and allows sunlight to pass through is used as the surface layer, and a material 2 such as a polyester blanket that is cold resistant and heat-retaining is used as the back layer and inner layer. It is an example.

FIG. 2 shows an embodiment in which a material 3 having a waterproof effect is used as the surface layer, and a material 2, such as a blanket, having a cold-proof effect and a heat-retaining effect is used as the back layer and the inner layer.
