Abstract

The subject of invention is a safety lock with a modified cylinder insert with one or several blocking pins guided by means of a locking and unlocking mechanism comprising a standard cylinder insert, with an entry hole located out of the key insertion axis, or an electromagnetic device. The safety lock with a modified cylinder insert according to the invention comprises a modified cylinder insert (1) which wears - within holes where there is a combination of cotter pins and springs in the case of a standard cylinder insert - one or several blocking pins (3) guided by means of the locking mechanism. In the basic execution, the standard cylinder insert mounted out of the key insertion axis is applied in the said mechanism to move the blocking pins (3), but it can be replaced also by the electromagnetic device which shifts a pin or pins, when activated.

Description

SAFETY LOCK WITH ADAPTED CYLINDER INSERT

The subject of the invention is a security lock with a modified cylindrical insert with one or more locking pins guided by a locking and unlocking mechanism with a standard cylindrical insert with an inlet hole located outside the axis of the key insertion or electromagnetic device. The invention belongs to class E 05 B 13/08 of the international patent io classification.

A technical problem that is successfully solved by the present invention is a structural solution of such a security lock that will allow the use of a standard building lock with a cylindrical insert and will provide effective protection against hacking in the way of damage from the cylindrical insert of the lock, its breakage, or other way of opening door by identifying the combination of a cylindrical lock.

Known solutions to standard building locks for entry and second doors are usually fitted with a cylindrical insert. Newer cylindrical inserts have different safety features that prevent damage to the insert. These include anti-fracture shield, drill protection, GPI system, etc. These systems contain tempered pins in the core and body of the cylinder, magnetic systems that have greatly increased the number of combinations. These systems greatly increase the cost of the lock, but do not reduce the number of mechanical damage. Despite the increase in price, there are professional burglars who pull the cartridge out of the bed with a special device (threaded mandrel on a metal prism). Doing so breaks the pins, destroys the combinations, and thus disables the lock. The mode is similar to pulling a cork stopper out of a bottle.

For classic locks, direct access to the keyhole is provided, which allows the insertion of foreign bodies, adhesives and similar materials that prevent normal operation or locking. lock the lock.

A security lock with a modified cylindrical insert according to the invention solves a technical problem in such a way that the adapted cylindrical insert has holes in which a conventional cylindrical insert has a combination of wedges and springs, one or more locking pins guided by a locking and unlocking mechanism. In the basic embodiment, the said locking mechanism for moving the locking pins uses a standard cylindrical insert, which is located outside the axis of the key entry, but can also be replaced by an electromagnetic device that moves the pin or pins upon activation. The security lock according to the invention can be installed in any door to the place where the standard building lock used to be without additional modifications to the door itself.

I will explain the invention in more detail on the basis of an embodiment and illustrations, of which:

Figure 1 is a cross-sectional side view of a security lock with a modified cylindrical insert according to the invention;

Figure 2 is a side view of a modified cylindrical insert in partial cross section;

Fig. 3 is an interior view of the outer shield of a security lock with a modified cylindrical insert according to the invention according to the first embodiment without a moving mechanism inserted;

Fig. 4 is a front view of the mechanism for moving the pins after the first embodiment;

Fig. 5 is a rear view of the mechanism for moving the pins according to the first embodiment;

A security lock with a modified cylindrical insert according to the invention shown in Figures 1 to 5 is shown in Fig. 1 in cross-sectional view. It consists of a standard building lock A, which is fitted with a modified cylinder insert 1 and a mechanism 2 to move the locking pin or pins 3 mounted in the modified cylinder insert 1.

A conventional cylindrical insert has holes designed for mounting wedges and springs whose position depends on the key insertion at the key insertion and only the correct wedge position allows the cylinder insert to be released and thus to rotate the core of the cylindrical insert.

In the case of modified cylindrical insert 1, these holes are used as a guide of the locking pin or pins 3 and may be extended further into the wall 4 of the cylindrical insert 1. The locking pin or pins 3 have a semicircular extension 5 with a hole 6 on the bottom. it can also move in a specially adapted groove 13 inside the outer guard 14.

Underneath the standard building lock A, there is a mechanism 2 in place on the outer face of the outer 5 shield to move the pin or. pins 3 of the security lock with a modified cylinder insert according to the invention, the operation of which will be explained on the basis of Figures 3 to 5.

The mechanism 2 consists of, in a suitably shaped groove 7, a flat, kidney shaped flat section 8 that is screwed onto the back wall of the cylindrical insert 9 and has a pin 10 on the front of the housing.

After inserting a specially shaped wrench 11, the shape of which can be seen from Figure 1, through the visible inlet hole 12, rotate it 180 ° so that the toothed portion of the key enters the core of the cylindrical insert 9. the core of the cylindrical insert 9, which also displaces the cylindrical insert 9, which also causes the locking pin (s) 3 to move due to the adhesion of the locking pin 10 to the hole 6 of the locking pin (s) 3.

In this way, in the case of locking the lock, the movement of the 20 adapted cylindrical insert 1 is blocked, and the first pin 3 also closes the inlet hole of the adapted cylindrical insert so that it is impossible to insert objects therein which could possibly clog the inlet hole or attempt to mechanically damage the adapted cylindrical insert 1 .

To unlock the door, move the cylindrical insert 9 with the key inserted 11 so that the locking pin (s) 3 can be lowered to allow the key to be inserted into the adapted cylinder insert 1. By turning this key, the door can then be opened.

Depending on the design of the adapted cylindrical insert 1, one, two or all (usually five) of the executed pins 3 can be moved by the mechanism 2 described. When performing the adapted cylindrical insert with a made one pin 3, it locks the inlet opening of the adapted cylindrical insert with the locked lock , to open, then io must be used with a key with properly designed notches for the rest of the combination of raised studs of the cylinder insert. In the case of all five pins 3, it is possible to rotate the adjusted cylindrical insert with a suitable flat object or a blind key after the offset of these pins.

The mechanism 2 for moving the locking pin or pins 3 mounted in the adapted cylindrical insert 1 according to the first embodiment shown in Figures 3 to 5 can also be replaced by an electromagnetic device which, when activated, moves the pin or pins 3 into the locking position . This eliminates mechanism 2, opening is possible by pressing a button via a wireless connection, and all other functions as well as the shape of the pin or pins 3 remain unchanged.

Depending on the options described and the combinations of the two cylindrical inserts, the number of combinations for opening is doubled, and the security lock according to the invention completely solves the originally posed technical problem by preventing direct access to the key insert. The insert is accessible only from the inside, but its position cannot be determined from the outside, so it is practically impossible to mechanically damage the lock, such as the lock. breaking, drilling. In addition, the lock structure shown makes it impossible to press various unwanted materials into the lock, which is especially important for exposed doors (eg, common dwellings, schools and other public spaces). The visible input hole 12 is merely a pass through channel for entering the key. The inlet hole 12 is simple in shape and any foreign objects can be pulled out or removed. we push forward into the empty space.
