Description

[Detailed Description of the Invention] This invention relates to a warning device, and more specifically, to a warning device for large vehicles to prevent accidents that are likely to occur when large vehicles make left turns.

Accidents involving pedestrians, bicycles, etc. occur frequently when a vehicle makes a right or left turn.

Especially in the case of large vehicles, especially trucks and trailers, the driver's seat and vehicle height are high and the distance between the front and rear is long, so there is a large difference between the inner wheels, and it is difficult to see the lower left side of the driver's seat than the driver's seat.
Most of the above-mentioned accidents involve such large vehicles, which has become a major social problem.

Measures to prevent such accidents include the revision of the Road Traffic Act, the addition of rearview mirrors, and, as shown in Figure 1, large vehicles such as trucks and buses have larger diameter wheels. Vehicle body 3 between front and rear wheels 2a, 2b
When making a left turn, a large space 4 is created between the vehicle and the ground surface, and when a rider on a bicycle or motorcycle who is stopping on the left side of this large vehicle and intending to go straight or turn left, the rider of a bicycle or motorcycle who is about to go straight or turn left will receive the left turn signal of the large vehicle. In addition, a protective frame is installed to prevent accidents in which the driver of a large vehicle inadvertently starts driving without noticing that the bicycle or motorcycle is on the left and gets caught in the rear wheel of the vehicle (the turn signal is difficult to see from the side of the vehicle). (Side bumper) 5 is installed.

However, this trap prevention frame is effective in the event that a bicycle or motorcycle collides with a large vehicle and falls over, and the driver of the large vehicle immediately notices the situation and stops, but the driver does not notice. Recent frequent accidents have proven that it is ineffective if it is delayed.

The purpose of this invention is to eliminate the accidents that occur in large vehicles, especially when turning left, as well as to reduce the number of accidents that cannot be prevented solely by the protective frame attached to the vehicle. is installed between the front and rear wheels on the left side or both the left and right sides, and a plurality of movable plates are attached to a protection plate that also serves as a frame to prevent entanglement, using elastic pieces such as springs to maintain a constant spacing. A sensing device with a contact piece and a corresponding contact point is attached to the movable plate, and when a human body or a part of the vehicle body touches the movable plate, the alarm device installed in the driver's seat and the vehicle body lights up and sounds, and the vehicle is operated. To provide a warning device for a large vehicle, which can detect that an accident is about to occur, involving both the person inside the vehicle and those outside the vehicle.

An embodiment of this invention shown in the drawings will be described in detail below.

FIG. 2 shows a state in which the warning device of this invention is installed on a large truck, and numeral 11 in the figure is the large vehicle to which this device is installed.

3 to 3 through the vehicle body 13 and support members 15a, 15b, into a space 14 created between the vehicle body (loading platform) 13 and the ground surface between the front wheels 12a and rear wheels 12b on the left side of the vehicle. As shown in Figure 5, there is a movable plate mounting/protection plate (hereinafter referred to as the protection plate).

) 16 is attached, and a plurality of movable plates 17a to 17e springs 18 are attached to this protective plate, and a plurality of movable plates 17a to 17e springs 18 are attached to this protective plate.Usually, a predetermined gap is created between the drawing plates. Moreover, when an external force is applied to the movable plates 17a to 17e, the spring 18 is pressed and the movable plates 17a to 17
e can approach the protection plate 16 side.

The protection plate 16 has two fixed contact pieces 20a-20e corresponding to the movable plates, and the movable plates 17a-17e have two movable contacts 21a-2 corresponding to the contact pieces, respectively.
1 e is attached, and these contact pieces and contacts are respectively connected in parallel to constitute a sensing device 23, and a fixed contact piece 20a
As shown in FIG. 6, an alarm display circuit 24 consisting of a power supply E, buzzers B1 and B2, and a lamp (or flasher) LP is connected between the movable contacts 21a and 20e and the movable contacts 21a and 21e. The buzzer B2 is disposed on the dashboard of the vehicle seat, and the buzzer B2 is disposed on the left side of the vehicle body together with the protection plate, so that a person outside the vehicle can be notified that a human body or other object has touched the sensing device 22. There is.

Further, as shown in a modified example in FIG. 7, a flashing unit 25 associated with the direction indicator lever is provided, and a xenon lamp 27 is flashed by a flasher unit 26, so that it can be easily recognized even in the daytime.

Further, the protective plate 16 and the movable plates 17a to 17e are all covered with a flexible sheet member 22 to prevent damage to the human body.

Although not shown, if the above-mentioned sensing device is installed not only between the front and rear vehicles on the left side of the vehicle, but also at the same location on the right side, behind the rear wheels, between the front wheels and the front bumper, the detection device will detect the problem when the vehicle is backing up in addition to when turning left. Accidents can be prevented.

Although not shown, the alarm display circuit 24 may be configured to be powered on when the key is turned to start the vehicle, or powered on when the left turn instruction switch is turned on. good.

The warning system of this invention is constructed as described above, so that when making a left turn, where many accidents occur, or when making a left turn after stopping at an intersection, a car or motorcycle running parallel to the left side of a large vehicle will be alerted. If a human body or the like touches one of the movable plates 17 a to 17 e and the fixed contact pieces 20 a to 20 e and any one of the movable contacts 21 a to 21 e come into contact with the vehicle, the dashboard will be damaged. In addition, the lamp LP and buzzers B1 and B2 installed on the vehicle body light up and sound to notify the driver and those outside the vehicle that a human body has touched the vehicle, especially in a place that is likely to cause an accident, thereby prompting the vehicle to stop. This can be done before an accident occurs.

As mentioned above, this idea is based on a protection plate that has a function of preventing entanglement between the left side of the vehicle, both left and right sides, and the rear side of the vehicle body and the ground surface, and a plurality of movable plates are fixedly fixed by using bullets such as springs between them. A sensing device having contact pieces and corresponding contacts is installed on the protection plate and the movable plate, and a buzzer, lamp, power supply, etc. is connected between the contact pieces and the contacts of this sensing device. An alarm display circuit is connected, the alarm display circuit is placed in the driver's seat, and the operation of the alarm display circuit allows the driver to sense when a human body or the like touches a specific part of the vehicle. The driver can immediately know that there is a cause of the accident, so accidents can be prevented, and accidents that occur when turning left can be significantly reduced. Part of the device also functions as a side damper, similar to conventional Moreover, it has the effect that there is no problem in driving.
