Description

Safety device for light bulbs locks

Object of the invention

The present invention relates to a safety device for locks bulbs, whose The obvious purpose is to protect the bulb completely a lock, including the key insertion slot.

The object of the invention is to prevent introduction of impurities, chopsticks, etc., into the groove of introduction of the corresponding key of a light bulb, as well as avoid drilling the bulb itself.

Background of the invention

Safety devices for light bulbs lock that are known so far, are constituted usually by a conical trunk piece coupled to the light bulb that is intended to be protected, leaving the key input, so through that input the bulb can be manipulated with false keys or disabled by introduction of chopsticks and impurities in that key slot.

In other cases, security devices they consist of a fixed body and a mobile car, making that lock by magnetic key or by common key. In this type of devices, although they offer high security, without however they do not offer resistance to drilling, to which there is to add the fact that in the opening position the bulb is free in its entirety and offers a poor aesthetic with respect to the closed position.

Description of the invention

The device that is recommended has been designed to solve the problem described above, in based on a simple but effective solution.

More specifically, the security device it is constituted from a solid hardened steel plate that it slides between the body or box and the guide of the cylinder of the same, in combination with the pythons that set the opening key, all with the complement of the introduction of a key that allows to establish that combination to achieve upward displacement or descending the commented hardened steel plate and place it, either blocking the hole or slot in the lock, preventing penetration or manipulation of any kind over that slot, or well move it down, even removing the same to free the lock slot and to carry open the opening by means of the corresponding key.

To achieve this, the steel plate hardened, which is rectangular and of small thickness, it has a longitudinal groove based on a succession of circular contours communicated through a strangulation, so that circular contours can house the corresponding pythons that form the key of the security device, and yet the bottlenecks that relate all those circular contours, only admit the passage of a narrowing of the respective anti-pythons facing the pythons properly said, all in order that when the key is inserted that forms the key, the pythons with their anti-pythons are arranged so that allow upward and downward displacement of the plate steel to position it in the groove sealing position of the bulb key, or for the downward position of the same and free that lock slot while when the key that forms the combination is removed, the pythons are left in a position where they do not allow the plate to move steel and therefore will remain in the position it had when it has removed the key, and if that position corresponds to that of lifting and therefore blocking the lock, the access to it and therefore introduce any type of object or manipulate, while if it has been removed and the commented plate of steel is in the down position, it can be carried open the bulb by means of the corresponding key, when the respective slot is free.

The ascending and descending displacements of the steel plate, which perform the closure or release of the groove of the lock, are made by a guided lever laterally in a slot of said plate, and emerging laterally through the body of the device, being tilting so that in its upward and downward tilt movements carry the corresponding downward travel and ascending of the commented steel plate.

In a variant embodiment, the drive It can be done by turning a single associated wheel conveniently to the steel plate.

This way you get that in addition to the own bulb protection, as is conventional, that is to say prevent drilling, integral protection occurs based on the commented steel plate when it is located in the position of lock groove of the lock.

Preferred Embodiment of the Invention

As you can see in the referred figures, the device of the invention applicable to lock light bulbs includes a body or box (1) in which all system elements, including a cylinder guide (2), whose profile can be that of the hitting bulb itself, a profile of round bulb or any other profile.

In any case, that cylinder guide (2) is fixed on the box (1) and will serve to couple the own security device to the lock that you want to protect and that it will also serve to house the set of anti-pythons (3) and springs (4) of the system which, in combination with the pythons themselves (5), will establish the combination or device opening system.

As you can see in Figure 5, the anti-pythons (3) have an extension extreme (3 ') that will affect the rear end of the pythons (5), by pushing the springs (4), determining one more area narrow in the vertical alignment formed by all pythons (5) with its counter-pythons (3).

The opening combination is established by the introduction of a key (6), as shown in the figure 2, key (6) that will make the pythons (5) remain all neatly arranged, and therefore faced the extremes (3 ') of the counter-pythons (3) with the function that will be exposed later. That key (6) is introduced through of a slot (7) provided in the case or body (1) of the device of security.

As a fundamental element, the device security for locks bulbs incorporates a steel plate hardened (8) that slides through a groove (9), being movable up and down, so that in the ascent position, as depicted in figures 3 and 4, that plate (8) seals the opening (14) for access to the lock a through which the opening key is inserted corresponding, while in the down position, as represented in figures 1 and 2, the commented steel plate (8) leave the opening (14) free, allowing the introduction of the key and therefore the opening of the lock.

The movements of elevation and descent of the shutter plate (8) are made using a side lever (10) that emerges through a side window provided in the corresponding body (1) of the safety device of the lock, so that this lever (10) is articulated in a slot (11) provided on one of the sides of the plate steel (8), this being in turn affected in the longitudinal direction of  a long groove formed by a succession of contours circular (13) joined by strangled sections (12), being the  amplitude of the circular contours (13) the same as that of the pythons (5) and counter-pythons (3), while the bottlenecks (12) have the amplitude corresponding to the ends (3 ') of the counter-pythons (3), so that when the key (6) is inserted and the combination is formed or alignment of the pythons (5) with their counter-pythons (3), then the steel plate (8) can move in the direction ascending and descending when the bottlenecks remain (12) facing the narrow sections (3 ') of the anti-pythons (3), while when the key (6), the offset between the pythons (5) and their anti-pythons (3), bringing the steel plate (8) cannot move and will be in the position it had before to extract that key (6), so that if that position corresponds to the lift, as shown in figures 3 and 4, then the hole or opening (14) is blocked for key entry to the light bulb of the lock, while if it remains in the position of descent, as shown in figures 1 and 2, free that opening (14) and the key can be inserted to carry out the opening.

Finally, say that the drive of the steel plate or seal (8), instead of being made by a lever, could also be done by turning in one or another sense of a simple wheel to get the ascending and descending displacements of the commented plate (8).
