Description

[Detailed Description of the Invention] This invention relates to an entanglement prevention device for vehicles equipped with double wheels, such as large freight trucks, mixer trucks, and trailers.

Currently, ordinary vehicles such as large trucks used for transporting cargo with a gross weight of 8 tons or more are required by law to be equipped with a certain standard of anti-entanglement devices on both sides of the vehicle body. (Ministry of Transport Ordinance Road Transport Safety Standards 18
Article 2) Many structural proposals have been made for these entanglement prevention devices in which a crosspiece or thick plate structure shown in FIG. 3 is attached between the front wheels and the rear wheels on the side of the vehicle body. (Utility Model No. 56-188750 and others) However, most heavy vehicles such as large cargo trucks, mixer trucks, and trailers are equipped with two sets of tires, front and rear.

Double wheels are often installed on the rear wheel, which carries the load, and sometimes there are also front wheels, but these double wheels have a gap of at least 20cm between the tires front and back, and there is a space of about 80cm between the tires and the upper fender. The delta-shaped triangular space s formed by the wheels and fenders is operated without any equipment, so there are no people in this space when they come into contact with each other.
There is a risk that bicycles, etc., may be dragged into the area.

That is, during operation, the two pairs of tires rotate in the front and rear of the double wheels, which acts like a gear to help pull in objects.

Therefore, if a person or object comes into contact with or gets caught between the double wheels, they will be easily drawn into the wide delta-shaped gap formed between the fender and the double wheels.

Furthermore, when a car turns right or left, the center of gravity of the car body moves outward due to centrifugal force, and the wheels also move outward between the shafts, so there is an even greater risk of death or injury due to being caught in the car. big. In this way, large vehicles equipped with double wheels have the problem of a driver's blind spot toward the side of the vehicle body, and the vehicle structure unique to double wheels also poses the risk of an accident caused by other vehicles equipped with a single tire. Extremely large compared to the vehicle.

Therefore, the conventional entrapment prevention device installed between the front and rear wheels cannot prevent the above-mentioned entrapment accident.

The law does not stipulate the obligation to install an anti-entanglement device to shield the space formed by the double wheels.

This invention was devised by the applicant, who, as a member of the vehicle operation industry, was concerned with the prevention of vehicle accidents and safety measures, and took into account the space formed by the above-mentioned double wheels and the special nature of the rolling action.

The gist of the present invention is that a triangular space formed between a fender and a double wheel of a vehicle body is provided with an inverted ladder-shaped strong and rigid metal plate or other thick plate to shield the space. It is.

An embodiment of the present invention will be illustrated and explained below.

FIG. 1 shows an entrapment prevention device according to an embodiment of the present invention, in which numeral 1 is a strong, rigid, thick-walled iron plate formed into an inverted ladder shape. The surface should be treated with paint, etc. to resist corrosion.

The upper edge of the inverted trapezoid plate is bent into an inverted L shape and serves as an attachment part 2 to the fender f. Although both side edges may be flat plates, it is better to provide bent edges 3 in a rounded shape as in the embodiment in order to prevent injury or damage in the event of cleaning the vehicle body or collision or contact with a human body.

4 is a mounting hole, and 5 is a tightening bolt. Reference numeral 6 denotes a reinforcing support rod which is fixed to the vehicle body in a direction orthogonal to the back surface of the plate to prevent the inverted trapezoidal plate 1 from bending in the event of a collision, and is attached by welding or removably. It may be attached to the lower surface of the fender f in an inverted L shape, and the inverted trapezoidal plate body 1 may be welded to this. (Not shown) 7 is a mounting plate screwed onto the tip of the support rod, and 8 is a mounting screw.

Although the above-mentioned embodiment shows one mode, the design may be modified and formed as appropriate, and the inverted trapezoidal plate may be formed into something close to a triangular plate, and the reinforcing support rod 6 may be omitted as the case requires.

As shown in FIGS. 1 to 3, the entanglement prevention device having the above-mentioned structure is installed, for example, in the delta-shaped triangular space S formed between the double wheels t and t of a large truck c and the fender f above them. The device of the present invention is installed in a size that does not hinder the rotation of the wheels.

The attachment means is fixed to the lower side of the fender end edge in a shape of a hanging shape, and the attachment part 2 is fixed with bolts, so that the reinforcing support rod 6 is supported and fixed to the lower part of the loading platform n.

Alternatively, it can be fixed by welding to the inverted L-shaped reinforcing support rod attached to the fender f.

As mentioned above, this application is a simple device for attaching a reverse ladder-shaped baffle plate that does not hinder operation in the space formed between the double wheels and between the fenders. Even if a pedestrian, bicycle rider, or other obstacle rushes into, comes into contact with, or collides with a space area during operation, the entrapment prevention plate prevents the entanglement or pull-in effect.

Pedestrians can prevent the risk of being drawn into the gap between the tires by holding down the entrapment prevention plate with their body or hands.

In this way, the present invention is provided as a simple and effective device for eliminating the structural blind spots peculiar to vehicles equipped with double wheels, which cannot be solved only by the driver's attention and eliminating blind spots.
