ES2415554B1 - Telescopic and foldable light trailer - Google Patents

Abstract

The invention consists of a light trailer for coupling to vehicles, by means of the usual devices such as ball or hook and whose main object is the transport of vehicles of small dimensions such as motorcycles or quads. For this, the trailer has a telescopic folding and extensible character, in which a rear overhang of variable length is defined by two or more telescopic extensions whose folded position allows the vertical placement of the trailer with a minimum volumetric occupancy

Description

OBJECT OF THE INVENTION

The present invention, as expressed in the statement of this specification, refers to a light trailer for coupling to loops, by means of the usual devices such as ball or hook and whose main object is the transport of small-sized vehicles such as motorcycles or quads, allowing that trailer can be stored in places of reduced space.

The trailer object of the invention solves several problems of which this type of trailers suffer; one is the bulky size that

it hampers its transport to the place where the trailer is left unused, especially in narrow places (aisles, doors, etc.), another is the high space required by the place where it is left unused, and on the other hand ease of loading process from the wheel locks to the trailer.

In addition to the advantages discussed above, the trailer

object of the invention can be used in lozenges of greater length to

the one established on a nominal basis since it has an extendable box,

being able to adapt to the length between axles of multiple loops.

BACKGROUND OF THE INVENTION

A feature of traditional trailer systems

for light vehicles intended primarily for the transport of vehicles,

is that they use a platform of fixed dimensions, at the same time that a lance for their connection to the tractor vehicle also of f ~ as dimensions, not being able to

vary neither for its suitability to the vehicle to be loaded, nor for its transport and storage. On the other hand, the vehicles must be charged by

an additional ramp that is usually of small dimensions, even reason

which the angle of the same is high with the consequent difficulty of

process, especially if it is done manually by pushing the vehicle to load. This process involves the possibility of having an accident when loading

the vehicles to transport.

Another of the major drawbacks of known trailers is the size for storage, not having the possibility to fold or retract, occupying an important space for the user that often prevents access through corridors and doors that are usually necessary to cross to access domestic storage places such as storage rooms, galleries, etc.

If removable transport systems are known, but

this implies a time of assembly and installation prior to its use and of equal

post-use form, for disassembly, which prevents rapid

use, as well as the possibility of losing components and having some cotton

accident during use due to bad assembly.

Central single-wheel transport systems are also known, giving extreme difficulty in loading the vehicles to be transported and added to this the low stability in their nonnal use and in transport.

DESCRIPTION OF THE INVENTION

The trailer of the invention has a new design on the basis of which it makes it possible to use it as a set that allows its extension and folding to facilitate its adaptation to the dimensions of the vehicle, its manual transport and its storage.

To do this, the trailer is based, on the one hand, on a system of

extendable box that can adapt its length according to the

dimensions of the load and pennite in turn reduce the rear overhang, up to

a distance less than the radius of the trailer wheel, making it possible to turn

of the same 90 degrees and therefore place it in an upright position for storage.

The trailer's lance has two articulations that hang its rotation with respect to an axis parallel to the axis of the trailer. Both joints have a locking system by means of pins and that for construction safety they also have a stop that only allows the turn in the direction of folding, in such a way that it does not affect a possible failure of the folding system during the operation of the trailer.

These two aspects, together with the reduced width or track of the trailer, especially in the case of being intended for motorcycles that are reduced to the width of the motorcycle, pennite its storage and transport through spaces of reduced space.

One of the articulations of the trailer has the use of the trailer as a loading ramp for the vehicle when it tilts its inclination. Once the center of gravity of the load crosses the axle of the trailer, it tilts on said axle, placing it in a horizontal position and blocking the

system by means of the corresponding closure and, if applicable, pins

security.

The vehicle itself to transport the join and tie to the

trailer increases the rigidity of the set, since it is tied with

its rear and front wheel, as well as in its central part to the fixed chassis attached to the trailer axle.

The trailer use cycle, from the folded position,

it would be the following: the lance is turned with respect to its joints placing the

horizontal trailer The tractor vehicle is tied and the

telescopic confonning the rear overhang. The joints are released

of the lances in such a way that the trailer tilts allowing the loading of the

vehicle. After loading, the trailer is placed horizontally, blocking the joints and extendable. Once the trailer is used, it is reversed for folding.

DESCRIPTION OF THE DRAWINGS

To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, this descriptive report of a sketch set is attached, based on whose figures will be understood more

Easily innovations and advantages of the device object of the invention.

Figure 1.- Shows a preferred arrangement of the deployed trailer object of the invention.

Figure 2.- Shows a preferred arrangement of the folded trailer object of the invention.

Figure 3.- Shows a preferred arrangement of the trailer object of the invention arranged for loading.

DESCRIPTION OF A PREFERRED EMBODIMENT

In view of the aforementioned figures it can be seen that the trailer consists of an axle where two wheels are arranged on which a fixed structure is arranged, whose rear overhang is less than the radius of the wheel and the previous overhang is less than the second joint (2) of the lance. A series of extendables (3) are arranged on said structure (Figure 1), so that the load structure can be made longer according to the dimensions of the vehicle. These extendable (3) are guided one above the other operating telescopically. The blocking of said extenders will be carried out by means of manual, automatic pins, thyme or any known means.

To facilitate the fixing of the wheels you can have

stops or grooves that prevent the movement of the wheels of the vehicle to be loaded,

such as those used in this type of trailers. In the front part it has a support (4), (figure 1), to tie the wheel of the vehicle to

transport with fmnez3.

The trailer's lance is attached to the axle and the fixed structure mounted on the axle and has two articulations (! And 2) that allow the rotation of the lance both for folding (figure 2), and to facilitate loading (figure 3 ) of the trailer. Said articulations (1 and 2) allow the rotation in only one direction, guaranteeing that no folding occurs during

vehicle running.

The trailer has at its rear a device

signaling, of fenders and a head of union to the vehicle of drag, S in accordance with the regulatory requirements of this type of trailers.

Claims (3)

1.-Extensible and foldable light trailer, intended for the transportation of vehicles, characterized in that it has a fixed structure, from which an axle with two wheels is part, and on whose fixed structure there are arranged telescopic and extensible elements (3) that Fonuan a rear overhang, as well as a front lance with two joints (1, 2), hanging the entire assembly to be able to place the trailer itself vertically. 2.-Extensible and foldable light trailer, according to claim 1, characterized in that the constituent lance of the assembled anterior element on the fixed structure, it establishes the coupling means to the corresponding tow tractor vehicle, presenting its posterior articulation in proximity to the wheel axle, while the previous articulation is intentional and pennite to place the front part of the lance in a horizontal situation and the back of it in an inclined situation. 3.-Extensible and foldable light trailer, according to claim 2, characterized in that the lance, through its joints, is foldable to reduce its volume in an inoperative and folded position of the trailer.
