Description

Portable protector for cylinders locks

Object of the invention

The present invention relates to a protector for the cylinder or bulb of any conventional lock, of those used on doors, shutters and the like, protector portable that is implanted on the door lock when the protection of the aforementioned bulb is intended, and that it is removable to allow access to said bulb, by the user or authorized person to access the interior of the passenger compartment try.

Thus the object of the invention is to protect the aforementioned door lock bulb or blind, front to the introduction therein of mud, chopsticks, pieces of cardboard, etc. what would block the lock making it impossible to opening.

Background of the invention

For their own purpose and functionality the access locks to a home or any other type of cabin are exposed to the effects of the weather, and by his position for the purposes of hooliganism.

In the first aspect and since the groove of the lock light bulb is directly accessible from the outside, the environmental dust accesses through said groove to the inside the bulb, depositing it and mixing with the lubricating grease that normally assists the lock, producing a kind of pasta that dries over time and that ends up disabling the light bulb. In the second aspect they are relatively frequent acts of hooliganism consisting of introduce different objects through the groove of the bulb, such such as chopsticks, clips, pieces of cardboard, etc., so that these objects block the passage of the key, are extremely difficult to extract and, consequently, functionally nullify the lock.

Trying to solve this problem are known locks that feature a practicable placket that close the slot of your bulb, which is a solution acceptable for the first part of the problem, that is to avoid the deposition of dust inside the bulb, but without However, they are not at all effective in the second aspect, since in the same way that the user of the lock can mobilize said placket to access with your key, you can do any thug to introduce one of the objects above cited.

Description of the invention

The portable protector that the invention proposes solves the problem fully satisfactorily previously exposed, in the two aspects commented.

To do this and more specifically said protector materializes in an anchor plate, intended for be attached to the door, shutter or element in question, circling the light bulb of the lock, plate that on his face later it has a housing for said bulb.

The aforementioned anchor plate is complemented by a closing block or protector itself, as a bowl, that fits perimeter to the anchor plate in a perimeter staggering of the latter, also counting said closing block with a central core, tightly attachable in an anchor plate housing and equipped with a mechanism lock based on retractable pythons against respective springs, key that attacks the locking block radially or laterally, which acts by mere longitudinal displacement within the corresponding accommodation, that is, without turning, and that in its introduction it acts on a pair of cams or plates of closure, which normally fit in a perimeter and internal groove of the aforementioned anchor plate housing, and against it in turn of springs that normally tend to the blocking situation of said cams.

According to this structuring the protector it is normally held fixed to the door or shutter through its anchor plate, immobilized by its own mechanism lock, completely covering the lock light bulb main or access lock to the cabin, which is hidden and inaccessible. When access to said cabin is required just insert the mentioned key into the corresponding slot of the protector, so that the unblocking of the block of closure with respect to the anchor plate, whereby said block Closing can be removed to access the main lock, with its corresponding key, which will preferably be the same as the one used to disassemble the protector.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Preferred Embodiment of the Invention

In view of the figures outlined you can be seen as the portable protector for cylinders or bulbs of lock that the invention proposes is constituted by a anchor plate (1), intended to be fixed to the door, shutter or carrier element of the lock to be protected, and a closing block or protector itself (2), the first represented in detail in figures 1 and 2 and the second in figure 3.

The anchor plate (1) incorporates in its face later accommodation (3), formally and dimensionally matching with the emerging sector of the light bulb or cylinder of the lock to protect, not shown in the drawings, open housing (3) by its limb (4).

Complementarily in said base plate (1) establishes a second housing (5), frontal, affected at the level half by a perimeter groove (6).

For its part, the closing block (2) configures a kind of bowl, which corresponds to the own reference (2), cylindrical as well as the anchor plate (1), destined to receive tightly in your breast and through your wall lateral, to said anchor plate (1), up to a limit situation defined by a perimeter step (7) existing in said license plate.

In the concave area of the bowl defined by the closing block (2) and in centered arrangement, a core (8), also cylindrical, formal and dimensionally suitable to the front housing (5) of the anchor plate (1), in which it is pluggable, counting said core (8) with a pair of flat, contraposed and intermediate housings (9-9 ') in which cams or plates are housed metallic (10-10 '), those shown in detail in the Figures 6 and 7, retractable against the respective tension springs (11-1F), so that such springs tend to have cams (10-101 fit into the perimeter groove (6) of the anchor plate (1), blocking the closing block (2) on said anchor plate and covering the light bulb of the lock, which as mentioned above is not He has represented in the drawings.

For the retraction of the cams (10-10 ') and consequent release of the block of closure (2), it is provided that in said closing block establish a lock mechanism based on a plurality of pythons (12), retractable against the tension of respective springs (13), so that said pythons (12) tend to be placed within a transverse groove (14), with opening side (15), for access and passage of a key (16) that unlocks the protector, and as previously stated will be preferably the same actuation key on the lock main that is being protected.

The introduction of the key brings, by itself same, a proper positioning of the pythons (12) so that produce retraction of the closing cams (10-10 '), and the consequent release of the block of closure (2) or protector itself, which can be removed to access the main lock bulb.

As seen especially in the section of Figure 5, the closing block (2), in mounting situation, does not reaches the backplane of the anchor plate (1), because the perimeter step (7) of the plate anchor (1) limits the degree of penetration of the bowl of the closing block (2), defining accordingly in the area anterior a hollow perimeter crown (18).

It only remains to note that the block of closure (2) has at least one lateral opening (19), for evacuation of possible particles, which opens the perimeter hole outside (18), and that it remains open in the mounting position for the closing block (2).

These openings (19) for evacuation of particles are smaller than the side opening (15) for access and passage of the key (16), in order to avoid confusion when entering the key (16).

In figure 1 they have been represented schematically the holes (17) of the anchor plate (1), to through which the fixation of the same is carried out to the door. shutter or element in question.

Claims (6)
