Abstract

PURPOSE:To facilitate mounting of a winter tire by fitting half tires bisected two along the diameter over a summer tire then fastening half tires by fasteners. CONSTITUTION:A winter tire 2 is bisected to form two half tires 2a, 2b along the diameter, and the inner circumferential faces of respective half tires 2a, 2b are made fittable to the outer circumference of a summer tire 1. Hard metallic reinforcing rings 3a, 3b are fixed to inner circumferential edge at the opposite sides of respective half tires 2a, 2b and coupling fasteners 4 are provided at the opposite ends of respective reinforcing rings 3a, 3b. By such arrangement, winter tire can be mounted easily by fitting half tires over summer tire then fastening half tires through coupling fasteners, resulting in facilitation of mounting/demounting of winter tire.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a tire for use in winter for self-propelled vehicles, primarily automobiles.

<Prior art and its problems> In order for cars to drive safely on snowy surfaces, they must be fitted with chains or replaced with snow tires.

In the case of a chain, it cannot be left on for a long time on roads without snow, so the chain must be removed again after it has been installed, making it very troublesome to install and remove it.

In the case of snow tires, the entire wheel must be replaced, and not only is installation and removal troublesome, but it is also impossible to purchase the tire alone; the entire wheel must be purchased, making the purchase expensive. Tsu〈.

OBJECTS OF THE INVENTION The present invention provides a convenient and easy way to assemble winter tires by fitting a 21-split winter half tire into a conventional summer tire and connecting both half tires with a fastener. It can be installed on the vehicle, and tires can be changed in 1
There is no need to install and remove tires for each wheel, and users only need to purchase and prepare tires for winter use, making it possible to provide tires that can be used economically. I made it.

Structure of the present invention The winter tire according to the present invention is composed of a pair of half tires divided across the diameter, and each half tire has an inner peripheral surface shape that can be fitted to the outer periphery of a summer tire. It has a structure in which a reinforcing ring made of hard material such as metal is attached to the inner peripheral edge of both the front and rear surfaces of the half tire, and connecting fasteners are provided at each end of the reinforcing ring to connect the rings. It is a thing.

The above-mentioned winter tire of the present invention is manufactured by first fitting one half tire onto the upper half of the summer tire of the wheel, then moving the car so that the wheel rotates approximately 1806 revolutions, and removing the half tire from the upper half of the wheel where the half tire has not yet been fitted. The remaining half tire is fitted onto the half summer tire, and the thus fitted half tires are tightly connected to each other using a connecting tightening device, whereby the summer tire can be attached.

Embodiment> Next, the present invention will be described based on an embodiment shown in the accompanying drawings.

In the figure, reference numeral 1 indicates a summer tire of a wheel in an automobile, and 2 indicates a winter tire according to the present invention.

The winter tire 2 is composed of half tires 2a, 2b divided into two parts across the diameter, and each half tire 2a, 2
b has an inner peripheral surface shape that can be fitted to the outer periphery of the summer tire 1, and reinforcing rings 3a, 3b made of a hard material such as metal are attached to the inner peripheral edges of both the front and rear surfaces of the half tires 2a, 2b. It is being

Therefore, each end of the reinforcing rings 3a, 3b has a ring 3a.
, 3b are provided with a connecting fastener 4 for joining them together.

There are various types of connection fasteners 4, such as bolt-and-tight types and latch types, and an example of the latch type will be described below.

The tightening device 4 shown in the embodiment includes a lever 5, a belt 6, and a latch 7.
It becomes more.

The lever 5 has one end rotatably attached to the pin 10 in the bearing 9 of the washer 8, and the lever 5 has an outer surface that engages with the pin 10.
A metal fitting 12 provided at one end of the belt 6 having a t is a pin 12.
The washer 8 is fixed to both ends of one half tire 2a.

A latch base 13 is fixed to the other half tire 2b, and a belt 6 is attached to the bearing 14 of the other half tire 2b.
A latch piece 16 having a claw 15 at its tip that engages with the teeth 11 of the latch piece 16 is attached with a pin 17.
is applied with a rotational force in one direction by a spring 18 so as to engage the die 15 with the teeth 11 of the belt.

Therefore, with this tightening tool 4, the shi-hachi-5 is raised,
Further, by rotating the latch piece 16 against the spring 18 and inserting the belt 6 between the latch base 13 and the latch piece 16 in the latch, the pressing force on the latch piece 16 is released. The latch piece 16 is connected to the claw 1 by the spring 18.
5 engages with the teeth 11 of the belt and is stopped from being pulled out. In this state, by tilting the lever 5, the no-fu tires 2a, 2b are removed.
You can connect and tighten things together.

Further, on the inner surface of each half tire 2a, 2b, an air cooling groove 19 extending in the width direction is formed by heat for an appropriate period of time.

This groove 19 is formed at one end by rotation of the wheel.
Both ports 19a and 19b are arranged appropriately in the width direction of the tire so that air is sucked in from the opening end on the side surface, and the air is passed through the groove 19 and exhausted from the port 19b on the other end (open end on the other side surface). It is offset and functions to dissipate the frictional heat between the summer tire and winter tire due to rotation.

Incidentally, the half tires 2a and 2b are appropriately provided with grooves, studs, and other means to prevent them from sliding on snowy surfaces.

Next, a method of using the above-mentioned winter tire will be explained.

First, one half tire 2a is fitted onto the upper half of a conventional summer tire on a wheel. Next, the automobile is moved so that the wheels are rotated approximately 180 degrees, and the remaining half tire 2b is fitted to the upper half summer tire to which no half tire has been fitted yet. The strained and fitted half tires 2a and 2b are tightly connected to each other using the above-mentioned connection tightening A4, and then attached to the summer tire.

According to the present invention, two effects are added to conventional summer tires.
By fitting the A-type winter half tire and joining both half tires together with a fastener, the winter tire can be installed quickly and easily.

In addition, there is no need to change tires for each wheel; only the tires can be installed and removed, and the user only needs to purchase and prepare winter tires, which has the advantage of being economical to use.
