Description

Trailers and cargo trucks with ladders. {A TRAILER HAVING LADDER AND A LOADING CASE OF TRUCK}

The present invention relates to a trailer with a ladder and a cargo truck, in particular, the opening and closing means including a fastener in the lower part of the loading of the ladder to the storage and storage of the ladder in the lower part of the loading box along the guide rail. It is equipped with a trailer and a cargo truck that can be provided to open and sealed to provide a convenient and safe storage of the ladder and at the same time provide a beautiful cargo box.

Generally, ladders are used to load goods, agricultural machinery, and heavy equipment in the loading boxes of trailers and cargo trucks, where the ladders are stored in a hanging form on one side of the loading box, and the ladders are used for loading the ladders. There is a method of using a ladder after storing it in a stacked form. The former requires a difficulty in selecting a hanging place of the ladder and a separate binding means such as a string, and it is very cumbersome and inconvenient to use the ladder by loosening the hanging and the string of the ladder. The latter is a problem that the painted part of the loading box is damaged or noise is generated while moving in the loading box while driving, and even if the shaking of the vehicle is severe, there is always a risk of a safety accident that a ladder may jump out of the loading box and fall. This occurred.

In recent years, a method for accommodating a ladder in a lower portion of a loading box has been devised and applied, and a characteristic configuration of a trailer (application number: 10-1999-027906) having a ladder storage device recently applied has been solved. If you look at the bottom of the storage box to store the ladder and to prevent the shaking slats and the stored ladder is fixed as a pin so as not to be released during the movement, and the locking step at the tip so that the ladder can be caught in the connection groove of the loading box to the ground Although it is configured to be formed, this is because the entire surface of the edge portion is moved close to the partition inner surface during the storage of the ladder, it requires a lot of force, and the problem that the foreign matter such as dirt accumulates and the noise that gives discomfort and discomfort occurs. There was a problem that the ladder is lowered to the ground After completely detached from the inside, the lifting jaw of the front end can be put back on the loading groove of the loading box and hanged.In case of storing, the inconvenience of going through the various steps is repeated. When the pin is dislodged due to the risk of pin loss and fluctuations during operation, the ladder is pushed backward and falls on the road, which implies the risk of safety accidents, and the exterior of the ladder is exposed to the outside. Various problems have arisen, such as giving a dirty feeling.

Therefore, the object of the present invention was devised in view of the conventional problems as described above, to prevent the accumulation of foreign matters such as soil on the guide rail, to store and store the ladder in the lower part of the loading box along the guide rail, and the rear door of the ladder At the same time, the opening and closing means including the fasteners are configured to be opened and closed to provide a loading box for a trailer and a cargo truck that can be conveniently and safely stored and at the same time give a beautiful appearance.
