Description

Extension system of floor space for trucks [0002]

More particularly, the present invention relates to an expansion system for a floor space for a truck, and more particularly, to an expansion system for a truck floor space, in which a space is formed at a lower portion of a loading box, And more particularly to an expansion system for a floor space for a truck that is easy to carry.

Generally, a top truck refers to a truck that is capable of sealing a roof, a side wall, and a rear side of a cargo compartment. Recently, a top truck of about 1 ton is used as a food car and a camper.

Conventionally, a food car and a camper car constitute a basic cooking facility in the inside of a tower. Normally, when such a cooking facility is built in the inside of the tower, the inside of the tower is excessively narrowed, .

In order to solve such a conventional problem, Korean Patent Laid-Open Publication No. 10-2017-0030840, entitled " Multifunction Floor Slide for Expansion of Vehicle Spaces ", discloses a floor structure capable of lifting objects or people, To form a wing-fold floor structure that can be used to raise or lower a portion of both sides of the floor.

In this case, the C-shaped rail is provided at both sides of the bottom floor structure of the wing folding structure, so that the wing folding C-type floor structure is formed. The rail hole where the bellows can be installed above the floor, Constructing an expandable slide floor structure comprising a housing and laural wheels and bearings so as to be movable along a C-shaped rail plate coupled to a floor structure of a wing fold C type, constituting an object space in which a capacitor can be installed, Type bottom structure is inserted into and coupled with an expandable slide floor structure so that anyone can easily attach and detach the same to a bottom floor of a conventional top-loading tower.

Therefore, the multifunctional floor slide for automobile space extension that can be used by attaching to the floor inside the tower of the tower can easily expand the space without economic loss, so that it can increase the visual effect and gives confidence to young entrepreneurs and even new entrepreneurs. It can greatly contribute to domestic and overseas economic development by increasing and creating jobs.

However, since the multifunctional floor slide for extending the automobile space of the top truck operates by installing the sliding structure on the top of the loading floor of the top truck, the total height of the top vehicle is increased to construct the same space as the existing top vehicle And when the total height of the overhead vehicle is made the same, the space used inside the tower is reduced, which makes the use inconvenient.
