Description

DESCRIPTION

Boat trailer

TECHNICAL SECTOR

The present application refers to a trailer for boats, of the type that carries a boat, sailing boat or the like pulled by a vehicle, such as an off-road vehicle, a tractor, etc.

STATE OF THE ART

It is known in the state of the art the existence of trailers to carry boats, sailing boats and other recreational vessels, easily towed by a vehicle such as a car, a tractor or even by a small number of people.

These trailers are lowered into the water via ramps to drop off or pick up the pleasure boat. Once the boat is placed on the trailer, it is retained by means of cradles.

This system allows the pleasure boat to be removed comfortably from the water, but it does not facilitate work on the bare metal (submersible part of the boat), since the cradles must be as low as possible to facilitate loading and unloading of the boat. In use, the body or base of the trailer is very close to the hull and prevents and complicates maintenance, updating or repair operations. For this reason, the boat has to be removed from the trailer, for example with a crane, to be able to do the work. This increases the time required for the machinery to be used and produces risks of the boat falling that is not as well secured as in the trailer.

The applicant does not know of any type of device that allows solving all these problems as simply as the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a trailer for boats according to the first claim. Its different variants solve the problems outlined.

The invention adds drop-down cradles to the structure of the trolley to be able to raise it high enough for comfortable work, without removing it from the trailer. This simplifies operations and reduces the risk of falls. What's more, there is no longer a need to use heavy machinery, so the boat owners can get the job done.

The boat trailer is made up of a wheeled base and a plurality of boat support cradles. These cradles comprise telescopic cradles and optionally shorter fixed length cradles (with respect to the position of maximum deployment of the telescopic cradles).

Preferably, the fixed length cradles are collapsible.

Telescopic cradles can be controlled in various ways, preferring to use internal chains (one for each telescopic cradle) that circulate inside the base, or in a tube attached to it, as a Bowden cable.

Other variants can be seen in the rest of the report.

DESCRIPTION OF THE FIGURES

For a better understanding of the invention, the following figures are included.

Figure 1: Schematic view of a first embodiment.

MODES OF EMBODIMENT OF THE INVENTION

An embodiment of the invention will be briefly described below, as an illustrative and non-limiting example thereof.

Figure 1 shows an example of a trailer formed by a base (1) with generally a single axle with the corresponding wheels. The base (1) has an end with a grip for the traction vehicle, and a series of cradles (2,3) to support the boat. In a novel way, all or several of the cradles (2,3) are telescopic cradles (2) to lengthen or reduce their length.

Those fixed-length cradles (3) can be foldable for removal with the telescopic cradles (2) unfolded. Thus, when the boat is supported on the telescopic cradles (2), above the fixed-length cradles (3), these can be removed to more easily access the live work.

Preferably, the fixed-length cradles (3) are arranged, in the longitudinal direction of the trailer, between the telescopic cradles (2), so that stability is maintained regardless of which cradles (2,3) the boat is resting on. It is also possible that the telescopic cradles (2) are inside, but it is less preferred for reducing stability.

The telescopic cradles (2) can be deployed by hydraulic or pneumatic means, for example by connecting to the corresponding coupling of a tractor, or by mechanical means using, each one, an internal chain (4) to the base (1) as a Bowden cable . Figure 2 shows an example of a link (5) of a usable inner chain (4). It can be seen how it has a front side, with a bar and a rear side with a hole that can be attached to the bar of the adjacent link (5). The hole and the bar of each link (5) can be parallel, orthogonal ... to modify the direction in which the inner chain (4) can be folded in each of its sections.

The trailer can incorporate legs (not shown) that hold and stabilize the trailer when the telescopic cradles are doing their job, so there will be no stability problems.

Claims (1)

1- Trailer for boats, formed by a base (1) with wheels and a plurality of cradles (2,3) to support the boat, characterized in that it comprises telescopic cradles (2). 2- Trailer for boats, according to claim 1, characterized in that it also comprises fixed-length cradles (3), with a length less than the unfolded length of the telescopic cradles (2). 3- Trailer for boats, according to claim 2, characterized in that the fixed-length cradles (3) are foldable. 4- Trailer for boats, according to claim 1, characterized in that the telescopic cradles (2) are commanded by internal chains (4) to the base (1) as a Bowden cable.
