DESCRIPTION

LIGHT TOWING. FOLDING. TRANSPORTABLE AND EASY STORAGE

FOR TWO-WHEELED VEHICLES

SECTOR OF THE TECHNIQUE

The invention consists of a folding, transportable, reduced and light trailer for the transport of two-wheeled vehicles, which we can store in a small space.

Corresponds to the field of accessories and accessories for the automotive industry. BACKGROUND OF THE INVENTION

The existing models on the market have been reviewed, but none have the lightness and lack the main features of the present invention. The easy handling, the possibility of storage in confined spaces, being able to transport it in a chest mode, and the characteristics of its folding differentiate it from what exists in the market.

EXPLANATION OF THE INVENTION

The invention arises from the discomfort suffered for years, for the handling and storage of traditional trailers.

This trailer is an easy-to-use compact and lightweight system for storing in tight spaces (closet, balcony, storage room ...). Thanks to its folding, dimensions and lightness it is possible to raise it in the elevator.

The simple design allows, by means of articulations and hinges, the folding on itself, reducing the length and volume, to a transportable cylinder such as a travel suitcase (Figure 3) with the handles (15) and wheels (17) incorporated, insert it into the The trunk of the vehicle or its small size and weight allows it to be suspended in the vehicle's hitch ball as if we were carrying a chest (Figures 9 and 10).

The total length of the trailer ready for use is 245cm, the total width is 130cm and the loading height 35cm, with a lane width of 15cm, which allows the loading of any motorcycle.

The weight of the set does not exceed 65 kg, which allows it to be transported suspended on the car's hitch ball.

These measures and weight may vary slightly but not much since it is important that the measures are adjusted to make it slightly bulky and quite light for folding and manual dragging.

For its folding we will follow the following steps:

Step 1: fold the front wheel stop by the joint (1).

Step 2: We lower the front wheel fixing system (11) which is adjustable by the pin (2).

Step 3: by means of the articulation (6) we rotate the lights-registration system (12) 90 ° placing it in parallel with the central body.

Steps 1, 2, 3 can be seen in Figure 5.

Step 4: fold the rear part of the trailer through the joint (5), releasing the fixing (9). Figure 6

Step 5: fold the front part of the trailer through the joint (3) by releasing the fixation (7). Figure 7

Step 6: releasing the fixation (8) we rotate the assembly 90 ° by the support (4) placing the assembly inside the wheels of the trailer (17). Figure 8

After finishing the previous steps we have a rectangular assembly whose ends are the wheels of the trailer (17) that holding it by the handle (15) we can lift it and transport it on its auxiliary wheels (16).

For its deployment we will follow the process in reverse.

The trailer has a Jockey wheel (13) to facilitate its handling, which does not need to be modified in the whole process, since it does not interfere in any of the steps and is fully integrated into the assembly.

For use as a trailer and to facilitate the ascent of the motorcycle, it is possible to tilt the central body, releasing the fixation (7) and the rear part of the trailer lowering on the trailer wheels (17), when the motorcycle wheel arrives to the fixing system (11) the joint (3) returns to its original position, and closing the fixing (7) we have the motorcycle held by the fixing system (11) to proceed safely to its mooring, with this solution not We need auxiliary ramps.

All steps, both folding and raising the motorcycle can be done without any tools, easily and without the need for help.

PREFERRED EMBODIMENT OF THE INVENTION.

The manufacture of the trailer is not complex, Steel has been chosen as the base material since it is easy to work, cheaper than other materials, quite resistant and as the whole is simple we do not have a high weight.

Steel structural tube is used for the central beam that acts as a chassis on which a U-shaped bent sheet steel rail is welded to support the motorcycle. This central beam is divided into three sections by two hinges to allow folding on itself.

In the front part we have the trailer hitch to the vehicle, screwed to the structural tube that will be folded about 45 ° and bent again 45 ° with a sufficient distance between the doubles so that when folding the assembly does not trip over the rotation system of the central beam on the wheel axle and raise the central beam to a sufficient height that when the trailer is attached to the vehicle it will be level.

After this bending we have the jockey wheel support and next to this soldier the sheet metal rail with the front stop fastened by two screws passed to

both sides of the rail so that it can swing and fold over it, we will also make three through holes laterally to the rail to place the front wheel clamping system that is a folded plate with a pin in the center to make a rocker that holds the Front wheel, these holes are for adjusting the fixing system to any wheel diameter.

In the central part we have a hole to place a pin and fasten the central beam to the axle of the wheels where some plates that hold a cylinder with two tapered bearings inside (similar to the steering pipe of a motorcycle) will be welded and by The center of these passes the pin that holds the central beam to the wheel axle, a threaded pin is also installed in the central beam to hold the assembly and a stop that only allows the central beam to rotate 90 ° in one direction ( the folding).

The quick closing for use in chest mode will be held in the center of the structural tube of the central part to allow the assembly to be centered to the vehicle.

At the back near the end we will make another through hole from top to bottom to insert a pin that will hold the license plate assembly - lights, composed of a metal plate where the license plate and homologated signal lights are screwed.

The wheel axle is made of steel with an approved suspension system, just like the hitch and quick release (10).

The fixings are closures like those carried by the trailers to hold the sides. The pins are metallic with thread to ensure that the joints will not move involuntarily. The stops and the joints are metallic, calculated and oversized for the weight and effort to which they are subjected.

The electrical installation runs through the interior of the structural tube from the front where we have the connector to the vehicle to the rear end where the license plate-lights assembly is located. The flexibility of the electric cable allows it to bend together with the joints to be integrated into the assembly and at the same time protected.
