Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a safety lock cylinder consisting of a stator and two opposing rotors, in particular for locking safety locks of the classical and safe type.

BACKGROUND OF THE INVENTION

Until now, various security lock inserts have been used to lock security locks, especially buildings, fixed to the door leaf by means of a screw screwed into the central threaded hole located below the lock latch. These security locks consist of a stator having a transverse recess for receiving the latch and dividing the stator into two parts. In both parts of the stator there is a rotor with a longitudinal continuous shaped hole for the control key in the upper part and with continuous vertical grooves in the lower part. The continuous shaped openings for the control key have the shape of a mirror, respectively. identical with their mirror location in the stator, allowing the use of a single control key. The stator has vertical grooves in both parts, in which the lower and upper locking pins, which engage the respective continuous rotor grooves, are mounted on the compression springs mounted on the bottom of the grooves. By inserting the correct control key, the facing faces of the lower and upper locking pins move to the level of the outer periphery of the respective rotor, allowing it to rotate and thus open or lock the lock. However, by inserting the wrong key, the faces of the lower and upper locking pins facing each other in the grooves do not move to the level of the outer periphery of the respective rotor, thereby preventing a portion of the protruding locking pins from turning the rotor and thereby opening the locked lock by an unwanted person.

The disadvantage of these security locks is that only one rotor is actuated by the control key at a time. Since behind the inlet portion the lock cylinder has only a short section of vertical grooves, a thin foil from the longitudinal through hole of the control key can be sensitively pressed all the facing faces of the locking pins to the level of the outer periphery of the respective rotor and then rotating the lock cylinder. When the safety lock cylinder is overcapped, the lower part of the stator can be drilled in the spring groove area, thereby damaging the springs and the locking pins will fall to the bottom of the grooves, releasing the rotor lock against the stator and rotating freely without using a key. Further manipulation of such a damaged lock is already very simple and nothing prevents non-violent opening of the door leaf.

These drawbacks are partially remedied by a safety lock cylinder, which consists of a stator and two rotors of uneven length, one of which is a release and the other is a shut-off. The release rotor is shorter and has e.g. four vertically extending grooves corresponding to the same number of vertical grooves formed in the stator relative to the closing rotor having e.g. seven vertical running grooves corresponding to the same number of vertical grooves formed in the adjacent portion of the stator. Two control keys are provided to lock and unlock this security lock cylinder.

This security lock cylinder is particularly suitable for locking flats, offices, warehouses, etc. In order to operate such a security lock insert, only one of the two operating keys must be used on each side, which differ from each other in the longitudinal mirror shape and in the inverted arrangement of the radial shaped projections in the first zone of the dimensionally longer control key. The shorter control key is only intended to operate the latch directly through the shut-off rotor. Such a security lock cylinder is therefore positioned in the door leaf in an oriented manner, with the release rotor outward from the locked object.

The safety lock cylinder in such an arrangement does not allow the closing rotor to be rotated 180 degrees with subsequent removal of the closing key.

SUMMARY OF THE INVENTION

The above mentioned drawbacks are substantially eliminated by a security lock cylinder, operated by two control keys, one short, release key and the other a long, closing key, with the long, closing key having a release zone, a neutral zone and a closing zone at the end with a clear orientation door leaf assembly, consisting of a stator with a transverse recess dividing the stator into two parts, each with vertical slots in which the lower split retaining pins are mounted on the compression springs, in the exterior of the stator there is a release rotor controlled by a long key release zone and interior part of the stator, there is a closing rotor fixedly connected to a pawl, rotatably mounted in the transverse recess of the stator, controlled by either a short key or a closing key of a long key, where each of the rotors has Measured vertical slots, in which the lower locking pins are slidably mounted and in the upper part a longitudinal through hole for inserting the control keys, which is based on the fact that the stator is fitted from the outside of the door leaf with a release rotor controlled by the long key release zone and inside the door the wings of the closing rotor fixedly connected to the latch, controlled by either a short key or the closing key of the long key, is provided with a chamber above the closing rotor in which grooves are formed with slidingly mounted upper locking pins on compression springs situated coaxially with grooves formed in the lower part of the stator below wherein the release rotor is provided with a first circumferential groove corresponding to the first locking element and the closing rotor is provided with a second circumferential groove corresponding to the second locking element located in the rear of the closing rotor.

The advantage of such a security lock is that the locking element is of the pin type.

It may also be advantageous that the blocking element is a divided circular segment.

It is also advantageous to firmly connect the latch to the closing rotor so that the closing rotor has a recess on the side of the latch corresponding to an internal alignment formed on the peripheral wall of the latch.

Advantages also include the fact that the short, closing key has a reduced profile at the end by an end cut-out located at its upper edge.

At the same time, it is also advantageous that the long, release key has at least one recess formed on the smooth edge.

An advantageous arrangement also resides in the fact that in the closing rotor a through hole is provided in the space of the interior part of the fitting for the insertion of the additional foil key.

DETAILED DESCRIPTION OF THE INVENTION

The safety lock cylinder 1 of FIG. 1 with control by two control keys, one short, release key 40 and the other a long, closing key 30. wherein the long, closing key 30 has a release zone at the root, a neutral zone at the end and a closing zone at the end, with unequivocal orientation It consists of a stator 2, provided with a transverse recess 13 dividing the stator into two parts, each with vertical grooves 7b, 7c, in which lower split retaining pins 8b, 8c are mounted on the compression springs. In the exterior of the stator 2, a release rotor 3 is actuated from the exterior of the door leaf (not shown in the figures) controlled by the release zone of the long, release key 30. In the exterior of the stator 2, a shut-off rotor 4 is fixed from the interior of the door leaf. rotatably mounted in a transverse recess 13 of the stator 2, operated either by a short, lock key 40 or a lock zone of a long, release key 30. The lock rotor 4 has a recess 41 on the latch side 6 which forms a fixed alignment 61 formed on the peripheral wall of the latch 6 joint. Both the release rotor 3 and the closing rotor 4 have continuous vertical grooves formed in the lower part in which the lower split locking pins 8b, 8c are displaceably mounted, and in the upper part a longitudinal continuous shaped bore for inserting the control keys. The stator 2 is provided with a chamber 5 above the closing rotor 4, in which grooves 7a are formed with slidingly mounted upper locking pins on the compression springs 8a situated coaxially with the grooves 7b formed in the lower part of the stator 2 below the closing rotor 4. 1, the release rotor 3 has a circumferential groove 9 corresponding to one pin-type locking element 10, and the closing rotor 4 is provided with a circumferential groove 11 situated in its rear part and corresponding to the second pin-type locking element 10. The arrangement of these locking elements 10 also corresponds to an embodiment of a short, closing key 40 having a reduced profile at the end by an end cut-out 42 situated at its upper edge and of a long, release key 30 having two recesses 31 located on the smooth edge. In the closing rotor 4, a through hole 12 is formed in the space of the inner part of the fitting (not shown in the figures) for the insertion of the additional foil key 20.

The safety lock cylinder of FIG. 2 has only a circumferential groove U formed on the closing rotor 4, which also corresponds to the location of a single recess 31 in the long, release key 30 and the upper locking pins 8a are not supported on the compression springs 7a of the grooves 7a. A safety lock cylinder of this type may only be mounted in the upright position to ensure proper operation of the upper locking pins.

The safety lock cylinder of FIG. 3 is secured against pulling out by the fact that the blocking element 10 fitted in the circumferential groove 9 of the release rotor 3 is divided by a circular segment.

By inserting the long, release key 30 into the security lock cylinder 1 unequivocally from the side of the release rotor 3, all locking pins 8a, 8b and 8c are pushed into the correct position and the key in the lock cylinder 1 can be rotated. Since the length of the long, release key 30 is the same as the length of the safety lock cylinder 1, both rotors 3 and 4 are simultaneously carried. Since the closing rotor 4 is fixedly connected to the latch 6, the latch 6 is carried along with the closing rotor. 4 to unlock or lock the lock. When the short lock key 40 is inserted exclusively into the lock rotor 4, the locking pins 8a and 8b are inserted into the correct position, thereby releasing the lock rotor 4 firmly connected to the pawl 6 and locking or unlocking the lock directly. Since the release rotor 3 does not perform any function in this case, it remains in the resting position and there is no need for the short, closing key 40 to operate the release rotor 3. For this reason, the closing key 40 is also shorter, virtually the entire length. While securing the object from the inside by turning the short, closing key 40 by 180 ° and then pulling it out, the latch 6, which controls the door closing system itself, will also move, but not up to the position of actuating the respective gate. For added safety, an additional key 20 is used which, after closing the object from the inside, is inserted through the lock fitting into the opening 12 of the lock insert 1 and prevents its unwanted rotation even when the split locking pins of both rotors 3 and 4 are fully drilled. it is secured against forcible knock-out by locking elements K).

The advantage of said solution consists in increasing the safety of the lock cylinder against unwanted opening by a foil, an identical copy of the original release key, or drilling, by adding a chamber 5 with grooves 7a and upper locking pins 8a from the side of the closing rotor 4 which is an integral part of this lock cylinder. By inserting the short lock key 40 exclusively from the closing side of the security lock cylinder 1, the upper locking pins 8a and lower locking pins 8b are inserted into a position allowing the closing rotor 4 to rotate by 180 ° and then pulling out the short key. to lock the locking rotor 4 again and the consequent profile blockage of the safety lock cylinder J by the release rotor 3 and thus the impossibility of operating the latch 3 even when using an identical copy of the original long, release key 30. Positioning the chamber 5 from the locking rotor 4 prevents undesirable manipulation with the upper locking pins 8a because of their large distance from the releasing portion of the face of the security lock cylinder 1 and the impossibility of its exact location, which is prevented by different profiles the molding and releasing side of the security lock cylinder. It is also impossible to use the opening foil due to the large narrowing of the transition profile of the closure rotor slot 4, as well as the impossibility of simultaneously actuating the upper 8a and lower split locking pins 8b. The correct operation of the lock cylinder is conditioned by the use of appropriate keys for that side of the cylinder and upon leaving the object, the closing rotor 4 is returned to its normal position (with the smooth side of the key up). It is also necessary for the security lock cylinder to be properly installed, with the release side to the exterior and the closing side to the interior of the object to be protected.

The invention is not limited to the exemplary embodiment described above, but other combinations are possible in which the described technical means can be replaced by technically equivalent means.

Industrial usability

The security lock cylinder with a release and lock rotor according to the invention is particularly suitable for securing the lock mechanism against unwanted intrusion of unwanted persons into apartments, offices and in general areas requiring increased protection, such as e.g. warehouses. If a known latch with external toothing is used, it is also suitable for securing security doors and safes.
