Description

DESCRIPTION

Lifting jack

TECHNICAL SECTOR

The present application refers to a lifting jack, especially advantageous for airplanes, drones or other aerial vehicles with landing gear.

STATE OF THE ART

In the world of sports and leisure aviation, including radio control of large planes or drones, it is common to fly or have to land at poorly prepared aerodromes or even some unforeseen meadow or terrain. This can cause damage to the landing gear, when hitting a stone, a pothole ... For its repair, it is necessary to raise the plane, similar to a car.

On the other hand, flight conditions, where weight and volume are limited and the height of the aerial vehicle is generally high, ensure that it is desirable to have a specific jack for this type of vehicle. In addition, the pilot is often alone in the field, so he cannot receive help.

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

BRIEF EXPLANATION OF THE INVENTION

The invention consists of a lifting jack according to claim 1. Its different variants solve the problems outlined.

It is a jack that allows the extraction, any manipulation or repair of a puncture or damage to the wheel or braking system to be carried out without the need for assistance, taking up little space and weight. It is a self-sufficient solution.

The lifting jack is made up of a triangle of bars, with a base, a first side and a second side. It has a coupling for the axle of an aerial vehicle wheel, in any of its modalities (fixed wing plane, autogyro, drone, etc.) in the vertex between both sides, preferably protruding from one side of the triangle.

To be able to fold it, it is preferred that the connection between the base and the first side is removable and that the second side is hinged at both ends to the other elements.

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

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 embodiment, where the jack is formed by a triangle of bars, with a base (1), a first side (2) and a second side (3). Each side has one or more bars to ensure the necessary resistance.

The base (1) is fixed to both sides (2,3): by a removable connection to the first side (2) and by a hinge to the second side (3). Both unions can be removable, for maintenance or replacement of elements. For example, the removable joint is by a threaded rod or screw and a nut or wing nut. A point of the second side (3) can have a fixer (6) to position the end of the base (1) when it is not coupled to the first side (2), ensuring that it remains stable in the folded position.

For their part, the sides (2,3) are joined, at the vertex, by a bar (4) or tube that protrudes from one side. The end of the bar (4) that protrudes has a coupling (5), intended to be hooked on the axle of the wheel of an airplane or light aircraft. In the figure, the coupling (5) is a cut in the bar (4) the bar (4) can be connected to the vertex by a joint (7) to facilitate the operation, if the coupling is directional, that is, it only It engages in a limited series of orientations, so it could not follow the turning movement when raising the aerial vehicle that will be explained later with support in Figures 2 and 3.

In this way, the user can open the junction of the base (1) with the first side (2) to flatten the jack, so that it takes up little space. The bars on both sides (2,3) can be misaligned to facilitate folding. To reassemble it, fix the base (1) to the first side (2).

In use, the pilot mounts the triangle, connects the coupling (5) to the plane, with the triangle lying down, so that it does not support the weight of the plane. At that moment, lift the plane, for example from the end of the wing, and propel the plane towards the triangle, as shown by an arrow in figure 2. This ensures that the triangle remains vertical, by its own weight, and under the wheel. (figure 3).
