JPS58118403A - Side slip preventing device on frozen road surface - Google Patents

Abstract

PURPOSE:To ensure safe running on a frozen road surface by making a side slip preventive claw provided on the inner frame of a tire chain device automatically bite in the frozen road surface to prevent a side slip when a car is running on the frozen road surface, etc. CONSTITUTION:Outer frames A made of wire ropes and formed in an annular shape by coupling a metal piece provided with a U-shaped groove 1 on one end with another metal piece provided with a push-in protruded button 2 on the other end are fitted to both side faces of a tire D, and inner frames B are fitted by using the outer frames A. A biting claw 5 biting in the snow surface is provided in one body with the inner frame B and is fitted to the outer frame A by means of a binding metal H. A side slip preventive claw 7 provided with a plate spring 8 brought into an elastic contact with the tire D is fitted to the inner frame B, and the preventive claw 7 is made movable up and down by means of an expansion spring E. According to this constitution, in case a side slip occurs while running on a frozen road surface, the side slip preventive claw 7 bites in the frozen road surface, thus the side slip can be prevented effectively.

Description

[Detailed Description of the Invention] This invention enables the vehicle to move freely when the road surface force 5 is frozen or when driving on an ice-plated road surface, by the wheels themselves working to prevent skidding on the frozen road surface or ice-plate-like road surface. This invention relates to a sideslip prevention device that allows for free movement.

Conventionally, when driving on a frozen or icy road surface in an automobile, etc., it has been necessary to wrap a chain around the tire D or use snow tires or spiked tires. Since the vehicle was traveling by stepping on an ice cube, the wheels would skid or spin, making it impossible to proceed as expected and causing the vehicle to stop.

This invention is such that when a car is traveling on a frozen road surface or an ice slab-like road surface, skid prevention claws 7 installed on the inner frame B automatically cough on the frozen road surface to prevent skidding and allow the vehicle to run freely. The purpose is

This invention will be explained based on the drawings.

Figure 1 shows elastic force. For example, at the end of the wire rope
Fix the metal fitting with the r-shaped groove 1 and remove it. Further, a metal fitting having a push-in convex potano 2 is fixedly attached to one end of the other end to form a band shape.

FIG. 2 shows a cross-sectional view of the shape of the push button 2. As shown in FIG.

FIG. 3 shows a state in which the push button 2 is inserted into the U-shaped groove 1 and the connecting fittings are connected to each other by pushing the push button 2 into the U-shaped groove 1.

FIG. 4 shows how the outer frame A is constructed on the side surface of the tire D.

FIG. 6 shows a state in which the sideslip preventing claws 7 are assembled to the pillars of the inner frame B, and the plate springs 8 are fixed to the sideslip preventing claws 7.

Figure 7 shows the relationship between the skid prevention claws 7 and the leaf springs provided on the sideslip prevention claws 5 when the inner frame B and outer frame A are formed on the side surface of the tire D, and also shows the relationship between the expansion and contraction springs. This figure shows how the side-slip prevention claw 7 inside the side-slip prevention claw 7 functions to move vertically and horizontally.

1 in FIG. 8 shows the relationship between the outer frame A, the inner frame B, and the tire D, and furthermore, a side-slip prevention claw 7 is located inside the inner frame B, and the receiver is stopped by an assembly stopper, and an elastic spring E is attached to the nail. The plate spring 8 fixed to the skid prevention pawl 7 contacts the side surface of the tire D, and the skid prevention pawl 7 freely moves left and right against the inner frame B. It acts so that it can be done.

This figure shows that when the wheels of the scale 2 in FIG. 8 skid to the left, the skid prevention pawl 7 bites into the frozen road surface and acts as a stopper.

As explained above, the second invention allows the outer frame A to be easily attached to both sides of the tire D. , ) has the effect of having symptoms.

Since the sideslip prevention pawl 7, which is independent of the second inner frame B, is integrated with the biting pawl 5 and automatically performs a series of movement operations, there is an effect of facilitating the running of the car.

[Brief explanation of the drawing]

FIG. 1 is a plan view showing the entire outer frame A. Figure 2 is a cutaway showing the push-in convex button. FIG. 3 is a plan view of the push button inserted into the U-shaped groove and the connection fittings connected. FIG. 4 is a perspective view showing the entire outer frame A on the tire D. FIG. 5 is a plan view showing the structure of the inner frame B and the biting claws. FIG. 6 is a plan view of the inner frame B and the sideslip preventing claws 7 assembled therein. In FIG. 7, a tire D is provided with an outer frame A and an inner frame B. FIG. 7 is a side view showing the plate spring 8, nut G, elastic spring E, etc. when the outer frame A and the inner frame B are connected to the sideslip prevention claw 7 by a connecting fitting H; 1 in Fig. 8 shows that when the outer frame A and the inner frame B move over the tire D, the sideslip prevention pawl 7, the catch G of the prevention pawl 7, the elastic spring E, the nut G, the control plate clamp 8, and the road surface. FIG. 3 is a cross-sectional view showing the claw 5 and the like. 2 in FIG. 8 is a cross-sectional view showing that when the wheel skids, the skid prevention pawl bites into the frozen surface and acts as a stopper, and the control leaf spring 8 becomes compressed on the side surface of the tire D and the inner frame B column.
