Abstract

The present invention concerns trailers or tow vehicles. In particular, the invention concerns a trailer with a light, tubular structure, completely demountable in order to form a minimum-volume packet and thus occupying a very small space for storage or for transport when not used as a trailer.

Description

DISASSEMBLE TRAILER

Object of the Invention

[I] In the use of trailers, particularly those designed to be dragged by common vehicles, such as cars, vans or all-terrain, there are two basic drawbacks, such as the weight of the trailer itself and its storage when not It's in use.

[2] With regard to the first case and due to both the load it carries and the incidents of the road (pavement irregularity, curves, stops and starts, etc.), the trailer is subjected to huge structural efforts that, for To solve them, it is necessary to build them with very resistant materials, such as beams 'T', double 'T', angular or other appropriate profiles, which necessarily affect and subtract the drag effort made by the vehicle. In other words, the vehicle has to carry a dead or useless weight, which is important given the characteristics of the tractive vehicle.

[3] As for the second drawback and because the structures, as mentioned, are weighed and formed essentially in one piece, they cannot be stored or stored except in the way they are found, that is, the same as they have during use, occupying a difficult space to obtain or that can be used for other uses.

[4] The purpose of the present invention is to overcome the aforementioned drawbacks in a practical and simple manner, using a lightweight and disassembled tubular structure.

[5] Thus, one of the objectives of the invention is to provide a hollow core structure, of low weight and at the same time resistant, capable of absorbing and supporting stress.

[6] Another object of the invention is to provide a towing structure that can be completely disassembled, thus making it possible to store it in a space that is a tiny fraction of the space it occupies in deployed form. Description of the Drawings

[7] The details and features that define the present invention are represented graphically in the accompanying illustrative figures, in which:

[8] Figure 1 is a projection view of the trailer, in condition of use, in accordance with the principles of the invention.

[9] Figure 2 is a projection and exploded view of said trailer.

[10] Figure 3 is a partial enlargement of the exploded view of Figure 2.

[II] Figure 4 is a view of the trailer in the pick-up or storage position. [12] In these figures, the various components that make up the trailer are shown, where the frame or chassis is a three-piece reinforced tubular body comprising two angled antero-lateral tubular portions (1), which are connected at their rear ends with another 'U' shaped tubular portion (Ib) to close the contour. In the space comprised by said chassis, a set of three boards or plates (3) are arranged, which fit by insertion, on the back, between upper and lower projections (6), resting on the remaining edges on supports (17) and in the intermediate part on crossbars (10) that seat at the ends in projections (11) of the tubes (1) and (la), by means of through screws (9).

[13] The tubes (1) and (la) have, at their front ends, curved plate terminals (7), which allow coupling with the traction tube (2) and securing with screws (8), which at its end previous free couples with the connection to the vehicle (not shown). Additionally, said tubes (1) and (la), comprise lower ears (19) for coupling with the damping leaf springs (15), which in turn are connected by means of clamps (14) in 'U' to the common axis (13 ) of the wheels (5). A pair of parafangos (4) are attached to the tubes (1) and (la) by projections (18) that extend laterally.

[14] From the foregoing, the relevant features of the invention can be deduced, such as the chassis configuration using tubular elements, which, as is known, have the maximum strength, weight to weight with a corresponding solid core for having a hollow core or empty Consequently, it also presents the maximum possible lightness for the same material.

[15] It can also be seen that due to the absence of welds between pipes and that all components are screwed together, it is very easy to disassemble and stack, occupying a minimum volume that can be used in two ways, whether it occupies a minimum storage space or, be carried inside another vehicle when its use as a trailer is not necessary. This property can be seen in Figure 4, where the plates or boards (3) serve as a base (once the whole assembly is disassembled) to place the rest of the elements on them, where the wheels, lying down, imprison the parafangos and the rest of the tubes and common axle of the wheels. In conclusion, the trailer is also portable, when it is not necessary to use it for the intended purpose.

Claims

[ 1 ] 1.A disassembling trailer, which comprises a resistant structure with a minimum of weight and assembled in separable pieces, characterized by a tubular frame of four bodies combined and coupled together by tongue and groove joints, which together form a support of support for a surface of plates or boards, an anterior extension for traction and a rolling assembly.

[2] 2. A trailer, according to claim 1, characterized in that said frame forms a frame or contour of nested tubes and secured with pin screws, where said nested tubes are removable and stackable with the rest of the components to form a portable set, intended to be stored or transported as such.

[3] 3. A trailer, according to claim 1, characterized in that said frame further comprises a traction tube and a rolling assembly defined by an axle common to the wheels connected to shock-absorbing leaf springs.
