Description

The present invention allows the driver to recognize the passing trajectory at the rearmost part of the truck bed, the passing trajectory of the rear wheel tire, and the passing trajectory around the cab when the truck (lorry vehicle) turns. Etc.).

When the truck turns, when explaining to the new driver about the truck's platform and cab movement, etc., conduct classes etc. referring to the vehicle information described in catalogs published by vehicle manufacturers etc. The new driver understood the structure and movement of the truck. In addition, the previous ordinary license can drive a vehicle with a total vehicle weight of 8 tons or less. However, when a new driver who has never driven a small ordinary car actually rides a truck, One reason for this is that even if the movements are explained, the meaning cannot be conveyed well, and accidents caused by the rear overhang (shocking) of the loading platform and accidents caused by the front overhang (head swinging) of the cab are unending. It is.

When a truck turns, the rear overhang (shock swing) that occurs at the end of the truck bed and the front overhang (head swing) that occurs around the cab can also be explained to new drivers through training. I couldn't tell you well.

The present invention has been made to solve the above problems, and the overhang measuring device according to claim 1 is a cylinder communicating with the through hole on the upper surface side of a plate-like member having a through hole at a substantially central portion. A swinging arm is pivotally supported on a body frame having a plurality of supporting points so as to surround the through hole on the lower surface side of the plate-like member, and a writing material guide is fixed inside the cylindrical member The writing material guide includes an urging means for urging the writing material inserted into the writing material guide downward.
The overhang measuring device according to claim 2 is provided on a main body frame including a plurality of fulcrum points so as to surround the cylindrical member on a lower surface side of a plate-like member provided so that the cylindrical member penetrates substantially in the center. The cylindrical member is provided with an urging means for urging the writing material inserted into the cylindrical member downward.
The overhang measuring device according to claim 3, wherein the fulcrum is a wheel pivotally supported on the lower surface side of the plate-like member and / or a protrusion provided on the lower surface side of the plate-like member. To do.

By adopting the above configuration, when the truck turns, it becomes possible to draw on the ground the front overhang (head swing) that occurs at the end of the truck bed (shock swing) or around the cab, It has become possible to convey the meaning of rear overhang (shock swing) and front overhang (head swing) to new drivers.

Next, after the chalks 10 and 10 are inserted into the writing material guides 2 and 2 as the writing materials, and the weight bars 4 and 4 as the biasing means are inserted above the chalks 10 and 10, the instructor holds the handle to the left. By operating and retreating, the trajectory around the cab and the trajectory of the left corner of the truck bed last part are drawn. By measuring the length of the two traces drawn and instructing the new driver how much the truck will overhang and affect the surrounding traffic, the new driver can recognize the vehicle feeling. I can do it.

The present invention is not limited to the above embodiment, and the writing material is not limited to chalk, but may be a crayon, a crepas, or an oil pen. The biasing means for biasing the writing material downward is an example of a weight bar, but it may be a coil spring or an air cylinder. Although the swing arm is supported on the main body frame, the swing arm may be supported on the plate member 1. The plurality of fulcrums provided so as to surround the through hole are not limited to two, but may be three or more, or may be a projection material or a combination of a wheel and a projection material.
