Description

LOCK AND BULB PROTECTOR AGAINST YOUR FORCED OPENING

OBJECT OF THE INVENTION

The present invention relates to an anti rape protector of

5 locks, which is intended to prevent easy opening of doors

simply by inserting a card or an x-ray through the gap between the

palastro and the strike and pressing on the slide of the latch until it is released from the spring that keeps it in the closed position, thus opening the lock without difficulty.

10 At present, approximately 80% of locks with mechanical cylinders, both those for sawtooth and point wrenches, and including those for security and armored doors, have ceased to offer security with which were conceived because of the diffusion on the internet of techniques such as that of the

15 opening without forcing the lock that has gone from being used in assaults by organized gangs to be accessible to all types of criminals, being a real risk of unwanted access to homes and premises, theft and theft.

Hence the importance of the present invention, which consists of a

20 lock protector that replaces the conventional spring and slip latch with one of two sandwich plates that protect the lock and whose outer plate protrudes a sliding plate that adjusts to the fence running vertically along the entire length of the male part of the lock and entering the female part of the jamb preventing leverage.

25 The advantages of the lock and cylinder guard object of the

The present invention versus the known is summarized in the following:

Protect the lock and bulb from opening

It is valid for 90% of the locks on the market with a European light bulb system.

30 They adapt and prevent with their plates that the lock is forced

or open the slip with tata.

The two-plate sandwich lock reinforces the door.

The bulb is protected against bumps, drills or torsion.

The industrial application of the present invention is found in the

industry of the manufacture of locks and specifically in the protectors of locks and bulbs.

BACKGROUND OF THE INVENTION

Although no invention identical to that described in this specification has been found. we expose documents below

found that reflect the state of the art related to it. Thus the document ES1009113U refers to a protector of

security for locks intended for use in the locks of access doors of homes and commercial premises, consisting of the union of two pieces. one of which, in a "U" shape, is attached by its

soul at the door, being provided with a hole in coincidence with the eye

of the lock and its wings have a through hole and its free end has an inward projection, while the second piece. Sliding on the piece fixed to the door, it has its upper outer side faces and

inclined bottom and internal holes have respective holes

blind, coincident, in the "closed" position, with the through holes through the wings of the fixed part to the door, having been provided that the sliding part possesses, for its union with the fixed part to the door, with respect to its face internal center a pair of projections that extend orthogonally

inward, outward and inward again in turn,

with the particularity that the sliding piece carries a pair of coils

powered by the corresponding batteries, a printed circuit and the keypad

for marking the opening combination.

It is an electronic lock very different from the mechanics of the proposed invention.

ES2257939A1 proposes a magnetic code protector for

locks, of the type you will use to hide the lock to protect from a

door trim, supporting a fixing plate, which in turn holds the rotating closing box, which swings by means of the fixed hinge,

once the rotating crankcase has been moved to its closed position, the slider slides upwards to contact the closing tab, in which

by inertia it falls into a definite hole in the closing nail, preventing its

opening and being in closed position, arranging the slide in

its upper part of a code based on circular magnets which, when confronted with the magnet actuator's code of magnets, attracts the slider, freeing it from the closing tab, the rotating closing box being open, provided that the actuator codes magnetic be

coinciding with that of the upper part of the slide. In this case the protection of the lock is based on the coincidence of the code of the magnetic actuator with e of the slide of the lock,

something very different from the mechanical protection of the proposed invention.

Document ES1052802U describes a safety guard for

electronic locks with mortise lock characterized by being

constituted by a sealing element of width such that it closes or reduces the

space between the electronic lock and the door frame or

window, and whose profile of the outer surface reproduces all or part of the profile of the electronic lock for which it is designed.

ES 1 064 077 U proposes a portable protector for bulb locks, with the purpose of covering the access slot to the bulb, being constituted by the functional combination of an anchor plate intended to be fixed to the door, shutter or carrier element of the lock to be protected, and a closing block that is coupled to said removable anchor plate, which is the cover or protector element proper of said light bulb and which in turn fixes the anchor plate with the collaboration of a lock own, operated by key. which will preferably be the same as that of the main lock. The solution here is to cover access to the bulb, something also different from the solution of the proposed invention.

ES2308900A 1 describes a protector for door locks, of the type comprising a metal plate located behind an exterior wooden plate, both provided with a coincident hole, through which a protector runs in which the lock cylinder is housed. , at whose ends it comprises two outer trims; that the opening of the hole of the metal sheet is integral with a cylindrical neck that crosses the hole of the outer plate and protrudes with respect

of this, to mount on its end and externally the bezel and on its

inside the protector together with the cylinder, which are protected by the neck

cylindrical against unwanted manipulations. Conclusions: As can be seen from the research carried out, none of the documents found solves the problems raised

as the proposed invention does.

DESCRIPTION OF THE INVENTION

The lock and bulb protector object of the present invention is constituted from two steel plates that are arranged inside and outside the door as a sandwich to protect not only the lock, but also the bulb and the fence against theft . The outside of said

lock is protected by a vertical rectangular outer plate

finished at the ends in semicircular arches to prevent leverage. and it presents in its lower part a truncated cone where a cemented rotating notch is housed so that it does not split or can

drill, with a slot where the key is inserted to access the light bulb and open the lock.

On one of the sides and from above below an inner recess of said outer plate two ambidextrous plates fit, one of which is fixed and held by four wedges, two above and two below and the other is laterally displaceable by hand until covering the distance separating said outer plate from the fence of the door, then fixed by captive screws, its function being to cover the gap between the lock and the fence of the door, making it impossible to leverage or opening maneuvers with tabs or sheets for Give the slip.

The inner part of the sandwich is constituted by an inner plate of the same measures as the outer plate, which by means of four thymes and threaded bushings of varying length according to the thickness of the door, holds said inner plate to the outside, being housed in said license plate

inside a handle with trim and square for opening by

inside the door due to slip slips, and below a keyhole between threaded holes for the bulb housing. Said handle is housed in a circular plate with four holes for

its fixing by means of thyme to said inner plate, being able to move said

fixing up to 34 mm down thanks to the height adjustment

it allows the elongated hole where the handle square and the stepped positioning of the threaded holes into which the screws that fix said circular plate (20) enter, in order to adapt to all the locks.

This is how an adaptable protection to the door locks turns out, whereby the light bulb is anti-drill and the anti-opening door by maneuvering of those that open it without forcing the lock.

A preferred embodiment of the present invention, referring to the aforementioned numerical references, can be based on two steel plates that are arranged inside and outside the door as a sandwich to protect not only the lock, but also the light bulb and fence, the outside of the sandwich being constituted by a

vertical rectangular outer plate (2) finished at the ends in arches of

half a point (15) to prevent leverage, which has in its lower part a truncated cone (1) where a cemented rotating notch (16) is housed so that it does not split or can be drilled, with a slot (17)

where the key is inserted to access the light bulb and to open the lock. Said outer plate (2) comprises an inner recess (18) where two ambidextrous plates (3 and 4) fit, which fit vertically on one of the sides of said recess (18), one of said fixed ambidextrous plates (3) and held by four wedges (19), two above and two below and the other plate (4) movable laterally to cover the distance that the

separates from the fence of the door, looking at that point of its movement

by captive screws (5), its function being to cover the gap between the lock and the fence of the door, making leverage impossible or

the opening maneuvers with cards or plates to make the slip give way to jump its hold and thus open the door without forcing it.

The inner part of the sandwich is constituted by an inner plate

(6) of the same measures as the outer plate (2), which by means of four screws (11 and 12) and threaded bushings (10) of variable length according to the thickness of the door, fasten said inner plate (6) to the exterior (2), being housed in said inner plate (6) a handle (7) with trim (8) and square (9) for opening inside the door by sliding the slide and below a keyhole (13) between threaded holes (14) for the bulb housing. Said handle (7) is housed in a circular plate (20) with four holes (22) for fixing by screws to the inner plate (6), being able to move up to 34

mm down thanks to the height adjustment that allows the gap

elongated (21) where it houses the square (9) of the handle (7) and the

staggered positioning of the threaded holes (23) into which they enter

the screws that fix said circular plate (20), in order to adapt to all

The locks.

This is how an adaptable protection for door locks turns out, whereby the bulb is anti-drill and the door is opened by

maneuvers that open it without forcing the lock.
