[0094] FIGS. 16A to 17 show different views of the mode of the fixing unit (100) where they have the nut mode but keeping the elements of the head (101) that allow their coupling with the mechanism of closing and opening (200). In the case of FIGS. 18-21, different views of the fixing unit in its bolt or screw mode are shown.

[0095] The security device for vehicle rolling device (1) object of the present invention has the main object of increasing the security level for an eventual subtraction of the wheel or rim of a motor vehicle mainly, the way of using said device consists in having a wheel (3) of conventional vehicle has a plurality of bores where these are generally passed through the middle cavity of the wheel where they are located, thus firstly inserts the fixing unit (100) the which is derived from the arrangement of its head, where it has a generally hexagonal shape, it is possible through the insertion of an auxiliary key, the generation of a torsional pair for its corresponding tightening, as it is done in a nut or stud conventional; once the fixing unit (100) is coupled, there is the insertion of the closing and opening mechanism (200) which is inserted so that when it enters this, the core spring (319) has a negative path derived from its interaction with the upper part of the head (101) since its diameter does not allow the entrance of said core spring (319), with the retaining extension (314) and the secondary insurance (316) housed in the combination drilling (312)) are not prevented from leaving said hole and staying in the cavities of the past drilling (103) and the oval drilling (104) in this way their retention is achieved regardless of the rotation of the casing since these will remain in their position until their eventual release; which is given by applying an external pressure to the main casing as well as a turn until an accommodation of the rolling device (204) disposed on the internal flat face of the main casing (201) when it comes in contact with the core bearing device (317) disposed in the upper part of the core head (301), that is why in the front wall of the main housing there is an indicator (250) which allows to identify the position of the primary insurance (313) in conjunction with the retention extension (314) and the accommodation extension (315); in the same sense it is important to point out that for the release of the closing and opening mechanism it is essential to raise the portion of the body where said lug is as well as the respective liberation of the brake that prevents its rotation, since the combination to return to his place of origin to the primary insurance (313), the extension of retention (314), the accommodation extension (315) and the secondary insurance (316); that is to say the combination drilling (312) depends on the rotation of the wheel where they are located since in a preferred embodiment of the invention a preferential rotation of between 150° and 190° with respect to the origin of the wheel must be carried out in order to achieve first the secondary insurance return, then a pressure is made on the main carcass to travel the core spring (319) and that this first traps the retention extension (314) in the combination drilling (312) subsequently a new turn is made to the original position where a lower pressure is made with respect to the first one where the return of the secondary insurance (316) is had to the cavity of the accommodation extension (315), applying a lesser force attends to the existence of a cavity smaller derived from the way in which the drilling is arranged, that is to say the oval drilling (104), otherwise, that is to say if a force of equal magnitude is implemented to the first, it is p rounds a new fall of the retention extension (314) that derives its output from the combination drilling (312), so the oval drilling prevents its fall and allows the core spring to trap the secondary insurance (316) again and in this way get your exit.

[0096] In case of forgetting the combination that releases the latches of the grooves in the fixing unit (100) there is at least a pair of partial drilling (202) located on the inner face of the main housing and where these are in coincidence with the partial boreholes (304), the partial bores have a thinner wall than the rest of the fixing unit (100), therefore it is possible to perform the insertion of auxiliary tooling in order to completely clear the partial drilling (202) whose knowledge and position is only known by the user from the position of the indicator (250) and could be in any area of the internal face of the main casing (201), once those holes are released a tool is inserted of pressure and are released in conjunction with the partial boreholes (304) of the combination core (300)
