Definitions

• the present invention relates to a door latch protection device. It applies in particular, but not exclusively, to the vehicle door latch protection thus allowing a quasi inviolability of said lock.
• the vehicle doors such as the front and rear doors, the side doors or rags, are equipped with a lock allowing them to be opened from the outside of the vehicle by means of an appropriate key, and from the inside. the vehicle by means of a handle or a mechanical or electrical device accessible inside the passenger compartment of the vehicle.
• the locks generally consist of a two-piece stator and a one-piece rotor; the rotor and stator assembly is mounted on the plate of the opening from the outside to the inside; the locking of the lock on said sheet is effected by means of at least one fastener element introduced from the inside, being fixed in a part of the stator and bearing on the hub of the handle, said sheet being sandwiched between the stator and the hub of the handle via a reinforcing plate.
• stator consisting of two parts, thus allowing to position the monoblock rotor, is generally made by casting from an alloy of zinc, aluminum, manganese and copper; the two parts of the stator are assembled in shape correspondence by means of pins. A protective cover is then positioned on the outer portion of the lock, generally secured to the stator by holding in force.
• the object of the invention is therefore more particularly to eliminate these disadvantages.
• the invention allows: - the maintenance in force inside said shield of the two parts of the latch stator,
• the invention makes it possible to make the lock almost inviolable, especially in case of attack of the lock by tearing from outside the vehicle.
• a latch Ve consists of a rotor Ro and a stator St in two parts Sti, St 2 .
• the stator St is in fact made of two parts Sti, St 2 , so as to allow the positioning of the rotor Ro inside the stator during the assembly of the bolt Ve, the two parts Sti, St 2 , are then connected. fixedly, for example, by pins, not shown.
• said projection fitting into a housing, in correspondence with formed in at least one of said two portions St 1 , St 2 , of the stator St, comprises a threaded bore Bl 6 whose central axis Bl 7 substantially corresponds to the main axis of said projection Bl 5 , which central axis B1 7 forms an acute angle ⁇ with the axis of symmetry ⁇ of the latch, said threaded bore Bl 6 opening towards the inner end of the stator St, which threaded bore Bl 6 is extended by a smooth bore Bl 8 of diameter greater than the internal diameter of the thread of said threaded bore Bl 6 , opening outwardly of the at least one of said two portions St 1 , St 2 , of the stator St.
• a first screw Vi 1 screwed into the aforesaid blind-threaded bore Bl 6 , supported on a wall, made for this purpose in a handle Po, associated with the bolt Ve, makes the said handle Po, the unrepresented plate the opening of the vehicle, said at least one of said two parts St 1 , St 2 , the stator St and the shielding Bl.
• a second screw Vi 2 whose main axis is substantially orthogonal to the axis of symmetry ⁇ of the latch, is screwed into said at least one of said two parts St], St 2 , of the stator St, and thus makes integral the stator St and said handle Po.
• a pin Go the main axis of which is substantially orthogonal to the axis of symmetry ⁇ of the latch Ve, is introduced into the other said at least one of said two portions Sti, St 2 , of the stator St, and thus secures the St stator and shielding Bl.
• the aforementioned pin GB can be replaced by a retaining element, integral with the other said at least one of said two parts Sti, St 2 , of the stator St, or belonging to the other said at least one of said two parts St 1 , St 2 , of the stator St, and thus secures the stator St and the shielding Bl.
