Abstract

Folding trailer for towing vehicles, especially two-track trailers, which has minimum folding dimensions and can easily be folded and folded down by one person in a simple way.

Description

Technical field

The subject matter of the invention relates to a collapsible trailer for connection for towing vehicles, in particular two-track trailers.

BACKGROUND OF THE INVENTION

Previously known folding trailer designs for two-track vehicles have a hull and a chassis in a fixed state, which does not allow minimizing the dimensions of a compound trailer.

The essence of the technical solution

The purpose of this technical solution is to create a collapsible trailer with the smallest possible folding dimensions, easy to fold and fold by one person without much effort. This is achieved by the trailer folding body, which allows the trailer to be unfolded and folded to a minimum footprint quickly and easily.

EXAMPLES

(a) Example of a folding trailer for a towing vehicle (mainly two-track)

The folding trailer according to the invention consists of a folding body consisting of a front face 1, a rear face 2, a left side panel 3 and a right side panel 4, all the parts mentioned here being connected to each other by means of pins 5.

On the left side 3 there is an independently suspended left wheel 6 as well as on the right side 4 there is an independently suspended right wheel 7.

The lower part of the hull is preferably formed from two hinged bases 8, each of which is mounted on pivoting hinges 9, which are connected to the adjacent left side panel 3 and right side panel 4 or also to the front face 11 and the rear face 2.

Alternatively, the lower part of the hull can be formed from a single hinged bottom 10, which is connected to the left side panel 3 or the right side panel 4 or also to the front face 1 or the rear face 2 by means of hinges 9.

Below the body is a drawbar 11 connected to the body so that the front face 1 and the rear face 2 are connected to the drawbar 11 by means of pivot bearings 12.

In the unfolded state of the trailer, both hinged bottom 8, respectively. One separate hinged bottom 10 on the drawbar 11. one separate hinged bottom 10 erected upwardly, wherein the left side of the body 3 and the right side of the body 4 together with the front face 1 and the rear face 2 are twisted and knocked together to occupy a minimum footprint.

The bucket is stiffened in an unfolded state by tightly fitting the two hinged doors 8 or one separate hinged base 10 between the front face 1 and the rear face 2 and the left side panel 3 and the right side panel 4, this arrangement being secured by at least one locking screw 13.
