Abstract

Security lock, which is characterized by the placement of an intermediate cylinder, between the cylinder or mobile, which enters the key to proceed to operate the mechanism of this and the main cylinder where the previous ones are housed, all with its corresponding pins; for adding one more pin; because the pins of the intermediate cylinder are one piece, all working at the same time and because if the key is not correct, the secondary cylinder will turn crazy, without being able to drag the intermediate, which is the one that will activate the mechanism of the lock.

Description

Safety lock.

Object of the invention

The present invention, as expressed by the set forth in this specification, refers to a lock safety in which when entering the correct key, the cylinder in which the key is inserted will turn, being able to do so right or left or opening system or close with it.

If instead we enter a key incorrect, the cylinder in which we introduce this one will turn crazy, of so that the mechanism to open or close will not work.

Background of the invention

We don't know any lock that gets that the mobile cylinder in which an incorrect key is inserted can go crazy

Description of the invention

The locks that exist in the market are They usually consist of a main cylinder made of brass, steel or other material, which has a certain number of pins, according to manufacturer and other secondary or mobile cylinder, of the same material, which is housed inside the previous one, this one also carries some pins that match in position with those carried by the cylinder main, so that when you enter the correct key, it may turn, if instead an incorrect key is entered, the cylinder will not be able to do it, because the pins of one and the other Cylinder will pass through, preventing its possible rotation.

The proposal of this utility model is incorporates a third cylinder or intermediate cylinder between the main and secondary, carrying the same number of pins and one more,  which will coincide in the secondary and intermediate cylinder, the difference is that the intermediate cylinder pins are linked together, all moving together, so that when entering the key, the secondary cylinder pins and the intermediate cylinder must match and be able to drag the cylinder secondary to the intermediate and that the cylinder pins main allow these two to spin together.

On the contrary if when entering a key incorrect, in the secondary or mobile cylinder, the pins do not will match and lift the intermediate cylinder pins, which at be all united, they will stay in the main cylinder, preventing the intermediate can not turn dragged by the Secondary 6 mobile, but allowing it to go crazy.

The pine tree will be placed random, in the secondary or mobile and intermediate cylinders, of so that the number of possibilities that a key can match is minimal, in the same way, that the measure will also be random In the main cylinder it will not be necessary to have a pine more, since the pins of this cylinder have the mission of keep everyone's tension in tension, given that cylinder carry springs.

This new pine can be placed in any of the rows that carry the locks, since some, the called flat, they usually carry two rows of pins, therefore, even if the intermediate cylinder pins are one piece, they will have to match those of the secondary or mobile cylinder.

It could be the case that when introducing the wrong key do not raise cylinder pins sufficiently intermediate, in this case you can not turn the key preventing the operation of the opening mechanism, this possibility is minimum

Brief description of the drawings

In order to make the description of the mechanism and by means of the drawings that Attached, not limiting, the following have been represented:

Figure 1.- Shows a scheme of a lock normal.

Figure 2.- Shows a scheme of the lock proposal

Figure 3.- Shows a scheme of the lock correct.

Figure 4.- Shows a section of the lock Proposal with the correct key.

Figure 5.- Shows a section of the lock without key.

Figure 6.- Shows a section of the lock With an incorrect key.

Preferred Embodiment of the Invention

In view of the different drawings of the Figure 4, it can be seen that the cylinders, main (a) and the secondary (c), are the usual ones in any normal lock, except that the main cylinder is larger in diameter.

The pins (e and f) in is these two cylinders also those used is normal locks, so your Manufacturing is the usual.

In the case of the intermediate cylinder (b) it will be in ring shape, with a longitudinal groove where the United pins.

These pins (d) will be the same as the remaining but joined at the top by a floor bar thermo-welding or could be embedded in a bar  cylindrical or rectangular ribbed and snapped in, screwed or glued.

Claims (5)

1. Security lock, which is characterized by the placement of an intermediate cylinder, between the cylinder or mobile, into which the key is introduced to actuate the mechanism of the latter and the main cylinder where the previous ones are housed, all with their corresponding pins; for adding one more pine; because the pins of the intermediate cylinder are one piece, all working at the same time and because if the key is not correct, the secondary cylinder will turn insane, without being able to drag the intermediate, which is what triggered the mechanism of the lock. 2. Security lock, according to claim 1, characterized in that for the mechanism of the lock to work, the cylinder pins must coincide in such a way that the secondary cylinder, into which the key is inserted, can drag the intermediate cylinder and that the third cylinder, the main one, where the previous two are housed, does not prevent the previous ones from turning at the same time. 3. Security lock, according to claim 1, characterized by its application to all systems and shapes of the locks, whether cylindrical, keyhole, oval, etc. and for its application to all types of keys, whether they are called flat ones, such as vertical ones that are shaped like a saw or other type of keys. 4. Security lock, according to claim 1, characterized by incorporating the mechanism for actuating the lock in the intermediate cylinder and being able to place the extra pine in any of its rows of pins. 5. Safety lock according to claim 1, characterized that it can be applied to any type of lock, whether for doors, locks, electrical devices, mechanical, electronic, etc ..
