Abstract

PURPOSE:To easily get out from a muddy place, by preventing racing of a tire on a snow road, a frozen road, a muddy road, or the like by utilizing sand. CONSTITUTION:By operating the button of a switch from a driver's seat, a compressor 8 provided on the body of an automobile is operated to produce compressed air 7, a compressed air discharge pipe is provided on the upper part of a nozzle, a sand discharge pipe to discharge sand from a sand container is provided on the upper part of the nozzle, and by reduction of air pressure in the nozzle due to blow-out of compressed air through the nozzle, the sand is sucked. By injecting sand in the sand container 5 to the rugged pattern of the tread of a tire for an automobile through the sand discharge pipe 4 and the nozzle 2, friction resistance of the tire is increased due to sticking many sand particles and slip of the tire is prevented.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The anti-slip device for automobile tires using sand according to the present invention injects sand onto the tread of automobile tires, which serves as an anti-slip material for tires stuck in snowy roads, ice burns, or mud. The sand particles attached to the tread greatly increase the frictional resistance of the tire tread, thereby making escape running possible.

0002

[Prior Art] Conventional technologies include snow tires, tire chains (Japanese Patent Publication No. 59-16962), rubber bands (Japanese Patent Publication No. 16962),
-3650) It is common practice to bury studs or install anti-skid devices on the tires to drive on snowy roads, icy roads, and deep muddy roads caused by melted snow. Snow tires require replacement, spiked tires are prohibited because they create dust pollution when driven on regular roads, and anti-slip devices such as tire chains that need to be attached to tires are prohibited. It is a well-known fact that if you neglect the work of attaching and detaching the vehicle, it will make a lot of noise, making it uneconomical to drive on normal roads.

0003

[Technical problem to be solved by the present invention] The present invention was invented in order to solve the uneconomical and pollution problems of the prior art, and the characteristic of its technical idea is that When a tire gets stuck on a snowy road, icy road, mud, etc., sand is sprayed onto the tire and an extremely large number of sand particles are sprayed onto the tire tread, thereby greatly increasing the tire's frictional resistance. This made it possible for people to escape.

[Means for solving the problem] The anti-slip device for automobile tires using sand according to the present invention operates a compressor by operating a switch installed in the driver's seat to create compressed air, and connects it to the compressor. The end of the air discharge pipe is installed at the top of the nozzle so that compressed air can be injected from the tip of the nozzle, and a sand container containing sand, which is used as a tire anti-slip material, is installed at an appropriate position on the vehicle body. The end of the sand discharge pipe provided at the bottom of the container is provided at the top of the nozzle so as to be substantially aligned with the air discharge pipe, and the end opening of the air discharge pipe and the end opening of the sand discharge pipe are connected inside the nozzle. located close together. If the inside of the nozzle is configured in this way, the compressed air will be injected vigorously and quickly from the end opening of the air discharge pipe inside the nozzle, so that the pressure inside the nozzle will be rapidly reduced by the fast air flow, so that the pressure in the surrounding area will be reduced. A suction force is generated to suck the sand,
Then, non-slip sand is sucked from the sand container through the sand discharge pipe, and the sand is injected along with compressed air from the nozzle tip toward the tire, causing many sand particles to adhere to the tire tread.
The sand particles in the tire tread rapidly increase the frictional resistance, making it extremely easy for the tire to escape from snowy roads, ice burns, and mud and continue to run.

[0005]

[Action] Inside the nozzle, which is depressurized by the rapid flow of compressed air, the inflow of sand from the sand discharge pipe is continuously applied, and non-slip sand is continuously deposited on the tire from the tip of the nozzle. The surface of the tread is covered with an adhesion of sand particles. The sand particles adhering to the tread are attached to the uneven surface of the tread as many adhering particles due to the moderate humidity of the humid tread surface, so the frictional resistance of the tire against the ground surface increases significantly. It is something that you will learn to do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The attached drawings show an anti-slip device for automobile tires using sand according to the present invention. The apparatus according to the present invention will be explained based on the drawings. If a tire gets stuck in a snowy road, icy road, or muddy area that impedes the vehicle's ability to drive, the vehicle is often in trouble because the tire will spin and the vehicle will not be able to get out of the way. In this way, if the tire is spinning and cannot be removed,
By pressing the button on the switch 9 provided on the driver's seat, the compressor 8 electrically connected to the switch is activated to produce compressed air 7, and the compressed air is passed through the air exhaust pipe 6 connected to the compressor, and the air exhaust pipe When compressed air is sent to the nozzle 2 connected to the nozzle 2, the fluid of the compressed air is extremely reduced in pressure inside the nozzle, so the sand of the anti-slip material is sucked and quickly sprayed from the tip of the nozzle 2. Sand 3 as an anti-slip material is placed in advance in a sand container 5 provided on the car body, a sand discharge pipe is provided in the sand container 5, and the connected sand discharge pipe 4 is provided on the upper part of the nozzle 2. A solenoid valve 10 is provided on the air discharge pipe 6 provided at the top of the nozzle, and a switch 11 electrically connected to the solenoid valve 10 is provided at the driver's seat so that the solenoid valve 10 can be opened and closed by the switch. Make it. By opening the electromagnetic valve 10 and injecting the discharged compressed air 7 from the nozzle, the sand in the sand container 5 is sucked into the sand discharge pipe 4 and discharged from the nozzle 2 to the tire 1.
Since the jet is directed towards the tire 1, the outlet of the nozzle 2 is
A nozzle 2 is provided on the vehicle body to make it possible to attach a large number of anti-slip sand particles to the uneven patterned surface of the tread. The power of the compressor is 12
The compressor is operated by a motor from a V or 24V power supply. The rotational force of the automobile engine may be transmitted to the compressor by a pulley.

[0007]

[Effect] The effect of the present invention in such embodiments is that on snowy roads, ice burns, and muddy roads, the uneven pattern of the tread retains moisture, so a large amount of anti-slip sand adheres to the tread and reduces frictional resistance. Increased tires made it easier to escape.
