Embodiment Construction

[0050] Now below, combined with reference Figure 1 to Figure 6 , the anti-theft device according to two different embodiments will be described.

[0051] As mentioned above, the general principle of the invention is based on the use of the hitch anti-theft device 1 .

[0052] In the example described, the hitch comprises a hitch head TA mounted on a trailer R; the hitch head TA has a cavity CA for accommodating in the hitch position a trailer mounted on a vehicle V or a tractor. Even hanging ball BA.

[0053] The hanging ball BA preferably has a complementary shape with respect to the cavity CA.

[0054] like Image 6 As shown, this hitch is suitable for securely connecting a trailer R to a vehicle V.

[0055] It is reminded here that preventing the theft of the trailer R equipped with the vehicle V is one of the purposes of the present invention; enabling the vehicle V to perform operations on the trailer R in the attached position is one of the further purposes of the p...

Abstract

The invention relates to an anti-theft device (1) for a coupling. The device includes a coupling head (TA). The coupling head (TA) is arranged on a trailer (R), and has a cavity (CA) for containing a coupling ball (BA) in a coupling position. The coupling ball (BA) has a shape that is complementary to the shape of the cavity (CA), and is mounted on a vehicle (V) so that the trailer (R) and the vehicle (V) can be firmly connected. The anti-theft device (1) also includes: a first or lower element (11), which is placed below the coupling head (TA); a second or upper element (12), which is placed above the coupling head (TA); and a locking tool. The first and second elements (11, 12) are firmly connected to each other through clamping tools (16, 16', 17, 17') so as to surround the coupling head (TA) and form a housing (1) around the coupling head (TA). The locking tool includes a flange, which is applicable to at least two positions (P1, P2). The at least two positions (P1, P2) includes a first or unlocked position (P1) in which the cavity (CA) is suitable for containing the coupling ball (BA), and also a second or locking position (P2) in which the flange (4) protrudes in the cavity (CA).

Description

technical field [0001] The invention relates to an anti-theft device, in particular to an anti-theft device for a hanger. Background technique [0002] One of the objects of the present invention is to provide an easy-to-use solution for securing the connection of a trailer to a vehicle and enabling the maneuvering of such a trailer when coupled to the vehicle. [0003] The invention thus finds a particularly advantageous application in the field of motor vehicle accessories for preventing trailer theft. [0004] According to the present invention, the term trailer refers throughout the following description to any type of system for attachment to the rear of a vehicle by means of a hitch. It may include, for example, a trailer, but may also include a trailer, trolley, low-load dolly or any other equivalent hitch system. [0005] Typically, the anti-theft device fixed to the trailer hitch is in the form of a jaw or housing comprising two interacting movable parts, the jaws...
