Abstract

(57) [Summary] [Purpose] When a vehicle such as a car is parked in the sun for a long time in the summer, the temperature inside the car rises significantly due to the sun's rays. To provide a lightweight, inexpensive, and conveniently portable light-shielding sheet that can reduce the temperature rise inside a car. [Structure] The opaque part 13 is made of a flexible material and is designed to block or reflect sunlight on one surface, and the large number of protrusions 16 are formed so as to be distributed over the entire other surface. A light-shielding sheet characterized by including a large number of ventilation holes 18 penetrating between both surfaces.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a light-shielding sheet, and is particularly suitable for light-shielding vehicles such as automobiles. It is.

0002

[Conventional technology]

In general, if a vehicle such as a car is parked for a long time in the summer sun, it may become exposed to strong heat. Sunlight can cause the temperature inside the car to rise significantly, but take appropriate precautions when outdoors. There was no plan.

0003

[Problem that the idea aims to solve]

This idea solves this problem by blocking sunlight and reducing the temperature rise inside the car. To provide a light-shielding sheet that is lightweight, inexpensive, and convenient to carry.

0004

[Means to solve the problem]

This idea is a light-shielding sheet made of flexible material, with a thick layer on one side. An opaque part that blocks or reflects sunlight, and an opaque part that is distributed over the entire surface of the other surface. and a number of ventilation holes penetrating between the two surfaces. The present invention provides a light-shielding sheet characterized by the following.

[0005]

【Example】

Embodiments of this invention will be described below with reference to the drawings. In one embodiment of this invention, shown in FIGS. 1 and 2, 10 is generally flexible. This is a light-shielding sheet made of a material that A surface layer 12 made of a sheet of synthetic resin such as polyethylene with a thermal temperature of 100°C or more is have. 13 is shaped by coloring the entire surface of this surface layer with paint, for example, silvery white. This is the opaque area formed. This opaque area blocks sunlight and reflects it well. is desirable. 15 is a polygon formed in a circular shape toward the inner surface. An inner layer made of the same material as the surface layer 12 and having a number of hollow protrusions 16; It is bonded to the surface layer 12 in an overlapping manner. This protruding portion 16 is formed when the light shielding sheet 10 is attached to a vehicle. It prevents the air from coming into close contact with the body, improves air circulation, and prevents the temperature of the air from rising. be. 18 is a diameter, for example, that penetrates the overlapping portion of the surface layer 12 and the inner surface layer 15. A large number of ventilation holes of approximately 4 mm in diameter prevent heated air from stagnation within the light shielding sheet 10. It has the effect of making you feel better. The size of this light-shielding sheet 10 is determined by, for example, the upper surface of a car. It is sufficient to cover the windshield etc.

[0006] In another embodiment of the invention shown in FIG. It has a section 16. In this invention, for example, a white nonwoven fabric is used on the front side as the light shielding sheet 10. It is sufficient that the entire structure is made of a flexible material such as The portion 16 does not have to be hollow, and the surface layer 12 and the inner layer 15 are made of an integral material. It is okay to do so.

[0007] The light-shielding sheet configured as described above can be folded or rolled up and stored in the car. When in use, for example, attach permanent magnets to opposing parts of the periphery and attach them to the vehicle body. or attach it to the car body using a magnet from above this light-shielding sheet. Alternatively, one side may be tied to a mirror mounting member or the like. By doing this, you can block the sun's rays and reduce the temperature rise inside the car. . According to a test result, in 30 minutes in a small passenger car under sunny skies with a temperature of 28 degrees Celsius, If nothing was used, the temperature rose to 36℃, but with commonly used car body covers, the temperature rose to 36℃. The temperature was 4°C, whereas it was 31°C with the light shielding sheet of this invention.

[0008]

[Effect of the idea]

Since this device is constructed as described above, it is possible to drive the vehicle in the summer sun. It can significantly reduce the temperature rise inside the car when the car is parked for a long time, and it is lightweight. It has the advantage of being inexpensive and convenient to carry.
