Abstract

PURPOSE:To simplify a manipulation and to reduce the nuisance caused by dust and noise, by fixing a spike shoe which is moved to a working position and housing position by means of a radially provided rod, on the outside of a wheel rim, thereby controlling the rod. CONSTITUTION:When a spike device 1 is used, a nut 17 is loosened, a rod 3 is advanced by a screw 12, thus a spike shoe 5 is moved outward, and a spike 14 is projected from the outside diameter of a tire so that the outside diameter of the spike shoe is formed to be in the shape of a circle. When the spike device 1 is not used, the nut 17 is fastened so that the spike shoe 5 is moved inwardly resulting in being housed. With this arrangement, it is possible to make a spike entrance and exit by a one-touch so as to simplify a manipulation.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention adjusts the lot outward on the spot when a car with regular tires enters an icy road while driving on a road, and prevents the appearance of spikes. This is a car that uses the same spike shoes to grip the frozen road, which is approximately the same as the outside diameter of the tire, and when it returns to normal roads, adjust the rod again and store the spike shoes inward before driving. Regarding a frozen road spike device.

(Conventional technology) Conventionally, when driving a car on frozen roads, chains were attached to regular tires to prevent tires from slipping, or spiked tires with metal nails etc. driven into the tire tread were used. .

(Problem to be Solved by the Invention) However, with this conventional ordinary tire in which a chain 7 is attached, attaching and detaching the chain is time-consuming.

They slip just like tires, and on top of that, they have the problem of being difficult to prevent from slipping in the lateral direction.Also, once spiked tires are installed, they are difficult to replace, so some of them are not replaced during the season. However, this has the problem that the expensive tires wear out quickly and are very uneconomical.

In addition, since spikes are worn even when they are not needed, the spikes constantly hit the road surface, causing noise and dust pollution, and repair costs due to damage to the road surface were enormous.

(Means for Solving the Problems) The present invention has been made to solve the problems of the conventional art, and its purpose is to solve the problem of a woman driving a car equipped with normal tires when a woman suddenly approaches the frozen road. - Even a person can set the spikes with a single touch, the set condition can be checked at a glance, eliminating imperfections such as seven throats, and there is sufficient grip force against skidding, and the tread is always maintained even when stopped. Our objective is to provide a icy road spike device for automobiles that can be gripped and retracted with a single touch when not needed, eliminating noise, dust, damage to the road surface, etc. As a means, in the present invention, a disk is connected to the rim or hub on the outside of the rim of an automobile wheel, and a plurality of lots are attached to the disk so that the axis thereof is oriented in the radial direction and the positions are freely adjustable in the coaxial direction. An arc-shaped spike shoe with a large number of spikes protruding from the top is attached to the tip of the lot, and the spike shoes form a circle, and are biased outward by a spring. The rod is moved outward to enlarge the outside diameter of the spike to approximately the same size as the tire, and when driving on a regular road, the rod is moved inward to store the spike shoe smaller than the outside diameter of the tire.

(Function) Therefore, the icy road spike device for automobiles of the present invention (hereinafter referred to as “
"spike device". ), a desk is connected to the rim or hub of a car, multiple rods are attached to the desk so that their positions can be freely adjusted in the axial direction, and arc-shaped spike shoes with spikes protruding from the surface are attached to the tips of the rods. The spike shoes are fixed to the tip of the rod and the spike shoes are formed into a circular shape, and the rod is biased outward by a spring, so just before the car enters the frozen road, the rod can be moved outward and adjusted to adjust the outside diameter of the spike shoe. By making the diameter approximately the same as the outside diameter of the tire, the spike shoe can grip the frozen road surface. In addition, the spike shoes are arc-shaped, so they always grip the frozen road surface, so there is no slipping when stopping, and the throat is biased outward by a spring, so the spike shoes grip the road's unevenness easily. Miyasu<,
The nasty shock is not transmitted to the car body. In addition, the spike shoe can be put in and taken out by simply adjusting the movement of the rod, so it can be done in a short time by a woman, and even if it is installed during the season, it can be easily stored when not needed, eliminating noise, dust pollution, and damage to the road surface. .

(Example) Hereinafter, an example of the present invention will be explained with reference to the drawings.
