[Conventional technology]

The improved lock insert for cylinder locks proposed by this invention can be used in places where defensive functions are required to cooperate, in particular as a locking mechanism of a door or gate, as a new locking device or as an old magnetic insert of a cylinder lock. It can be used as a replacement.

Magnetic inserts for cylinder locks have become superior to cylinder lock inserts, which have been used since ancient times, because they allow for a large number of variations and are highly safe, and their range of use continues to expand. Dedicated. U.S. Pat. No. 4,576°025 discloses a magnetic lock insert for the locking mechanism described as a prerequisite to the present invention, the detailed construction of which is also important for the insert of the present invention. This will be explained with reference to FIGS. 1 to 7.

A lock cylinder 2 is arranged within a lock body 1 of standard dimensions, which lock cylinder 2 is rotated from its rest position in FIG. 2 towards an open position as shown in FIG. 4 by means of its own key 3. be able to.

Now, if the lock cylinder 2 is rotated further, the bolt carrier connected to it will displace the latch of the lock mechanism,
The locking mechanism is thus opened. Rotation of the lock cylinder 2 from its basic position is carried out exclusively by its key 3.

In the main body of the key 3, three permanent magnetic disks are formed on both sides of the key 3 in a nest (nesυ), which is generally three in number and has a circular cross-section. A magnetic code is formed.

The sign is as follows. In the round magnet disk, that is, the key magnet 12, a north-south dipole magnetic field is formed by dividing it in half by the neutral line, as shown in FIG.

Within an angular range of 360°, the neutral line is randomly located starting from 0° at the angular pitch characteristic of that given system, i.e. the north-south pole, displaced by different angular pitches with respect to 0°. Dipole magnetic fields can be formed depending on a number of planned variations. According to the prior art, six types of dipole fields are obtained with an angular pitch of 60°, which ensures maximum deformation. Six types of magnetic fields built into one key realize 6' = 46,656 variations.

Supports 2 on both sides of the key 3 located in the lock cylinder 2
Inside, on each side, three rotors 6 are arranged and are provided with round magnetized disks or rotor magnets 5. The rotor magnet 5 is made of the same material as the magnetized disk of the key 3, that is, the key magnet 12, and the rotor magnet 5 is magnetized in the same manner as the key magnet 12. Arranged on the rear side of the rotor 6 are chord-shaped incisions forming a frustoconical cross section, these incisions serving to accommodate the latch elements of the lock cylinder 2. After attaching a suitable key 3 to the key channel 0 of the lock cylinder 2, the dipole magnetic field on the key magnet 12 is connected to the dipole magnetic field of the rotor magnet 5 fixed to the rotor 6 through the wall surface of the key channel 10. The torque exerted and due to the interaction caused thereby causes the rotor 6 to rotate into the open position corresponding to the code of the key 3. A continuous latching channel 11 is now formed in which the notches on the rear side of the rotor 6 are aligned. Under the influence of the torsional moment advanced against the lock cylinder 2 by the key 3, the lock cylinder 2 tends to rotate, but the latch stop member (in this case formed as a latch 8) As can be seen from the figure, spring 13
is brought into contact with the wall surface of the latch groove 9 of the lock body 1 in the basic position under the influence of , and rolls along the arcuate wall surface of the latch groove 9,
The other end is guided and displaced into the opening 18 of the rotor 6, which sinks into the latch channel 11, so that the lock cylinder 2 can rotate around the lock body 1 corresponding to the position in FIG. 4. In this case, if an incompatible body or an incorrectly coded key were used during the release, the latch channel 11 of the rotor 6 would be damaged due to the interaction between the dipole magnet positions of the rotor magnet 5 or if an incorrectly coded key were used. A mismatched key in the position coded - remains in an unaligned position due to the effect of the magnet 12 and is unable to accommodate the latch 8 contacting the back of the rotor 6;
The wall surface of the latch groove 9, that is, a part of the latch 8
The lock cylinder 2 remains in a blocked position within the lock cylinder 2, and the lock cylinder 2 cannot be rotated even if an attempt is made to turn it with force.

The partial view shown in FIG. 3 shows that when one's key 3 is inserted into the key channel 10 and the sign of the key magnet 19 is correct, the rotor magnet 5 rotates in the appropriate direction, forming a continuous latching channel 11. Indicates the state in which However, the latch 8 is still in contact with the wall of the latch groove due to the force of the spring 13, and this position corresponds to the basic position of FIG.

In the structure described above, the insert of the cylinder lock is fitted with seals 4 rings 14° 15, since in a small space there are several moving parts, the correct and reliable operation of which affects the applicability of this structure. This seal ring prevents contamination from the outside and
Additionally, a spring-loaded spherical device with a steel catch is incorporated in the bore 16 to counteract the latch 8 being accessed by boring.

This device can prevent the key 3 from being pulled out outside of its basic position and fixes the opening to the closed position of the locking mechanism.

A recess 17 is formed in the latch 8 in order to prevent the usual axial withdrawal even if the latch 8 is perforated.

In this case, if on the rear side of the rotor 60) two latch channels 11 can be formed instead of one latch channel, this embodiment being indicated by the dashed lines in FIG. The rotor 6 occupies one position upon insertion of two differently coded keys 3, in which position one of the latch channels 11 can accommodate the latch 8, resulting in a locking device with a master key. can be obtained.

[Problem to be solved by the invention]

Magnetic locking mechanisms play an important role in the field of anti-theft. This type of locking mechanism cannot be opened with special thieves' tools, and by making the building equipment appropriately thick, the lock can withstand even the roughest methods. There is. However, after a certain period of use, the magnetic insert of the cylinder lock becomes contaminated and becomes locked, making it increasingly difficult to open. This condition reduces the reliability of the cylinder lock insert. Periodic soak cleaning with some type of solvent may alleviate some of the problems described above, but not everyone is capable of regularly disassembling and cleaning cylinder lock inserts.

Pollution comes from several aspects, external pollution is caused by the following situations: That is, fine particles that enter the locking device from the surrounding environment and are partially collected by the magnets can accumulate over time and prevent the rotor 6 from sitting accurately in position, thus impeding error-free operation. becomes.

The sealing rings 14, 15 are usually made of rubber, synthetic or silicone material and are able to exclude contamination from the outside to a considerable extent, and at the same time ensure that the lock cylinder 2 is set in the correct axial position so that the lock can be secured. Cylinder 2 and lock body l
It can reduce the wear and tear.

Internal contamination occurs after repeated use, as particles of material that flake off from the friction surfaces as a result of the guiding friction that occurs during operation can accumulate over time and interfere with the correct installation of the rotor 6. , which becomes an obstacle to its error-free operation. In addition to contamination, there is an associated problem of lubricant consumption, which necessarily increases the coefficient of friction significantly, making the friction surfaces rougher and causing binding and jamming of the lock insert of the cylinder lock.

The abrasive friction is applied to the rear end of the latch 8, the opening 1 of the rotor support 4.
8, as well as the latch channel 11 of the rotor 6.

Reduction of sliding friction and lubrication of the lock mechanism, as confirmed by practical experience, can be achieved exclusively by using petroleum-based lubricants whose composition is suitable for cleaning and lubricating the lock structure. can be solved. Generally speaking, the use of other lubricants will cause the rotor 6
is braked and cannot be set to the correct open position. Cylinder locks traditionally use graphite in the insert, which is intended to reduce sliding friction. Powdered graphite is not a material that is heat-resistant because the sliding friction against the magnetic insert of the cylinder lock is large, and the powdered graphite aggregates with other material particles that have come off during the friction of the rotor 6, causing the rotor to brake. As a result, it becomes an obstacle to properly setting the rotor 6 to the open position.

The most important thing when manufacturing a lock mechanism is the key magnet 12.
The strength, magnetization precision, and torque of the rotor magnet 5 are such that each member can smoothly take the closed position.

In the process of actual application, the torque generated by the interaction between the key magnet 12 and the rotor magnet 5 is
If the space is filled with zinc alloy, the mutual distance is 2
If the space is filled with air, it is reduced by the cube. inevitably,
If the highest possible torque is to be achieved, the spacing between the key magnet and the rotor magnet must be reduced to a minimum. An embodiment of the lock insert of the cylinder lock in the prior art is equipped with two key magnets 12 fixed to the key 3 as shown in FIG. 7, and having two key magnets means that the cylinder lock of FIG. This is also true for key 3 of the lock insert, and 6 key magnets 12
is placed. Thus, 6 key magnets 1 for key 3
2 can simultaneously rotate six rotor magnets 5 into coded open positions at the same time.

As already emphasized, in practice 60° on one circle
Six types of dipole magnetic fields are generated at equal angular positions of , thus obtaining 6' = 46,656 variations.

Many magnetization processes used today do not allow sufficient precision in setting the rotor 6, so the magnetization precision is 6.
It cannot be increased significantly beyond a pitch of 0°. Pivot-type cylinder locks with wide circles,
35,000 variations are sufficient for practical use. This number of variations is 5' = 15 by changing 6 pivots to 5 different dimensions.
, 625 has been realized, and the number can be further increased by changing the form of the key.

To achieve a suitable number of variations with respect to the magnetic lock insert of the cylinder lock, each of the two key magnets is pressed into a respective single nest of the key 3. This configuration has the advantage that it is possible to obtain a large number of variations with a relatively small number of rotors, and that high accuracy can be obtained with six types of rotors, but as a result of simplification, it has the following disadvantages.

The key magnet 12 has to be made extremely thin in order to avoid increasing the thickness of the key 3, which at the same time increases the wall thickness of the material between the key magnet 12 and the rotor magnet 5. Because you have to let it happen. A wide key channel 10 allows relatively high torsional torques to be applied using a non-conforming body, while a small thickness will not be able to withstand the large pressures applied to the rotor 6 by the latch 8. . In order to avoid interactions between the thin key magnets 12, the magnets must not be completely magnetized, and only lines of magnetic force that return to a roughly U-shape must be generated within the key magnets 12. Therefore, complete magnetic saturation cannot be achieved,
Inevitably, a weak key magnet 12 remains after the treatment, as if it were given a linear parallel magnetization, as is commonly done for rotor magnets 5.

Due to the relatively thick key 3, the wall between the key magnet 12 and the rotor magnet 5 is also thick, with the result that the interaction torque is considerably reduced.

By extracting the key 3, only the interaction between the key magnet 12 and the rotor magnet 5 occurs; Force different non-coded positions. These effects are weakened by the relatively large wall thickness, so that, for example, due to contamination of the rotating rotor 6, an out-of-normal position is not formed even after the key 3 has been withdrawn, thus reducing the safety in the closed state. It will be damaged.

In known magnetic lock inserts for cylinder locks, two independent actuating magnetic circles are formed, which are shown as dashed magnetic field lines 20 in FIG. However, there is an interaction between the magnetic lines of force that distorts this interaction and makes correct setting of the rotor 6 difficult.

The purpose of the invention is to eliminate the disadvantages of known inserts for cylinder locks, to extend the service life of magnetic inserts for cylinder locks, to increase operational reliability, to eliminate maintenance, and to manufacture economically with a simple mechanism. It is possible,
Moreover, the purpose is to allow for a large number of variations.

[Means to solve the problem]

The basis of this invention is to eliminate the access of foreign objects, which is the source of unreliable operation, so that the magnetic insert of the cylinder lock can operate with high reliability. The purpose is to eliminate the need for maintenance. Another purpose is to change the magnetization of the key magnet to
The goal is to achieve a better angular pitch by magnetizing along the entire thickness, compared to the 60° pitch in the prior art, which reduces the number of key magnets (while reducing the number of key magnets). , the same number, or even more variations than can be achieved with prior art techniques.

In the course of research to solve this problem, the inventor started with the following magnetic lock insert for a cylinder lock mechanism. That is, the magnetic lock insert comprises at least one lock cylinder rotatably disposed within a standard lock body, said lock cylinder comprising a magnetic lock insert of the lock. Connected to the bolt carrier of the locking mechanism, the lock cylinder has a permanent magnet disk, i.e. a center housing a key, with a key magnet magnetized in a chordwise or diametrically north-south polarity with a predetermined angular pitch. a key passage located in the rotor, said key passage being surrounded on both sides by respective nests, and in which a support for complementing the lock cylinder to the cylindrical rotor is rotatably embedded in the rotor; The axis of rotation corresponds to the key magnet inserted into the key passage, and in each rotor a fixed rotor magnet is provided, which rotor magnet is similarly magnetized as the key magnet and is located opposite the rotor magnet. One or more notches are formed on the side of the rotor, the notches forming a continuous latching passage within the rotor support at the point where the rotor magnet is turned to the open position by the effect of an inserted key. A latch groove facing the opening is formed in the inner wall of the lock body, and in the basic position of the lock insert the latch member is arranged so as to be guideable and movable. A steel member is provided for determining the relative position of the lock insert with respect to the lock body for securing an inserted key not in its home position within the keyway and for inhibiting drilling of the lock insert in the locking mechanism.

According to the invention, this lock insert is improved in the following respects: preventing the access of impurities caused by external contamination and internal friction during the use of the lock insert of cylinder locks; and to ensure accurate rotation of the rotor box into the open position, the latch member is in contact with the walls of the latch groove at only one point along its cross-section and, in at least one cross-section of the opening, with respect to the opening. It is characterized by being fitted in a form-closed manner.

In order to increase the number of variations of the cylinder lock inserts as well as the interaction between the rotor magnet and the key magnet, the thickness of the magnet corresponds to the thickness of the key, and on the other hand, an angular pitch of up to 20° throughout the thickness The key magnet magnetized is characterized in that it is surrounded on both sides by rotor magnets magnetized identically to the key magnet.

In a preferred embodiment of the magnetic lock insert of the cylinder lock, the latch member is constituted by a latch which extends within the opening in the rotor support and which connects the rear side of the latch and the wall of the latch groove. and a latch channel of an intermediate member interconnecting the latches.

The intermediate part can be easily fitted into the form of the opening in the rotor support, with the result that no dust is introduced into the interior of the rotor support, even in the area of the latch channel.

In the above-mentioned configuration, the intermediate member is preferably a spherical fitting made of steel that is closed in form and freely displaceable to the diameter of the opening, but in the simplest case it is a cylindrical fitting that meets the general requirements. It can be a roller or a cylindrical rotor.

In a preferred embodiment, the key magnet and the mouth-to-taper magnet are magnetized with a pitch of 11', in which case mechanical strength is increased and a large number of variations can be achieved.

According to the improvement of the lock insert of the cylinder lock of this invention,
By modifying the latch member, wear caused by rubbing contact and jamming caused by lack of lubrication can be eliminated. There is virtually no separation of material particles from the friction surfaces that is inevitable with normal rubbing contact, and malfunctions and misfits due to improper rotor setting are eliminated. By adopting a closed structure, malfunctions caused by external contamination can be completely eliminated.

As a result of the lower friction, the demand for lubricant is lower; in the closed embodiment of the cylinder lock insert, only one application of lubricant is sufficient, whereas in the open embodiment the maintenance required and the number of times of lubrication can be reduced.

As a result of the stronger magnetic field, stronger and safer cylinder locks can be produced without reducing the number of variations below internationally acceptable standards.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The structure and function of magnetic inserts in cylinder locks, as well as their attendant drawbacks, have already been explained in the preamble to this specification and will not be repeated here.

FIG. 8 is a sectional view showing details of the magnetic lock insert of the cylinder lock improved according to the present invention. As can be seen by comparing FIG. 8 with FIG. 1, the latch member has a configuration different from that of the prior art. As can be seen in the cross-section of FIG. 9, a latch member is used instead of one single channel 8, which latch member sinks into the latch channel 11 after turning the lock cylinder 2, as well as the latch 8. and an intermediate member 8a that interconnects the latch groove 9 of the lock body 1.

As can be seen in FIGS. 9-11, this intermediate member is a steel ball which fits diametrically and form-tightly into the opening 18 of the rotor support 4, and which is can be moved within the opening while at the same time isolating the interior of the rod carrier 4 from the outside world.6 As can be seen from the partial sectional view in FIG. 13, and at the same time the latch 8 is narrowed in width so that the intermediate member 8a can fit between the latch 8 and the latch groove 8 without jamming. The distinct arrangement of the latch 8 and the intermediate member 8a is ensured by a nest formed on the rear side of the latch which fits in the form of the intermediate member 8a. As can be clearly seen in Figure 11, the lock cylinder 2
During the rotation of the intermediate member 8a, in the case of a steel ball, it rolls on the wall of the latch groove 9 and sinks smoothly into the opening 19 of the rod support 4, so that the appropriate key 3 When turned by , the latch 8 can sink into the latch passage 11.

In FIG. 12, three different variants for the formation of the intermediate member 8a are shown. A steel ball is fitted into the nest 19 of the latch 8 on the left, a customary roller is fitted into the center nest 19, and a cylindrical rotor meeting the general requirements is fitted into the right nest. In Figure 13,
The latch 8 is visible in its cross section in contact with the intermediate member 8a, ie the ball, while in FIG. 14 the cross section of the latch 8 is shown in contact with the barrel-shaped intermediate member 8a. . In FIG. 15 an embodiment of a cylinder lock insert, to be precise, two parts thereof can be seen, the latch 8 having two, three or four intermediate parts 8.
a, in this case the number of openings 18 in the rotor support 4 corresponds to the number of intermediate members 8a, but the intermediate members 8a have a single contact with the same length as the latch 8. It is formed by a needle roller, which fits into an opening 18 in the rotor support 4, the size of which corresponds to the size of the needle roller. Needle roller (
When this roller sinks into the nest 19 of latch 8, it cannot move in the longitudinal direction against latch 8), on which two recesses 17 are visible, as is known in the art.
The role of the recess 17 is to prevent the intermediate member 8a and with it the latch from being pulled out when force is applied.

16a-C show the encoded magnetization patterns applied to the rotor magnet 5 and the key magnet 12. FIG. 16th
In figure a, after being magnetized, the rotor magnet 5 and each key magnet 12 of each car have a dipole magnetic field polarized north-south, and the limit position and direction that separate the north and south poles are:
Each shows the pitch of magnetization in the angular direction.

If the vertical limit line in Figure 16a is set to 0°, then
The angular pitch of 60° given to the magnets of cylinder lock inserts belonging to the prior art is shown in dotted lines.

In contrast, if according to the invention the rotor magnet 5 and the key magnet 12 are assigned a much smaller angular pitch, e.g. 11° (Figs. 16b, 16c).
), the number of possible codes would be tripled.

Apart from the fact that assigning pitch angles narrower than 11° requires extremely high precision in the magnetizer,
It is considered undesirable. It is only because the common area of the support on the rear side of the rotor 6, which does not turn into the open position due to the use of a non-conforming object or a non-conforming key, uses a latch that is pressed against the non-conforming object or the same object. , resulting in a deformation of the latch 8 or the rotor 6 being reduced so much that the deformed member causes the latch 8 to deform.
This leads at least to the disadvantage that the latching channel 11 can be stretched into the latch channel 11 which is somewhat rotated by force. As can be seen in FIG. 17, which shows the most unfavorable case, the rotor 6 and latch 8 are in contact with each other.
The compressive strength of the surface allows it to take the loads generated by the torsional torque of a mismatched body or a mismatched key inserted into the key channel 10 without causing any deformation.

The embodiment shown in FIG.
Although the cross-section of the lock insert of the cylinder lock of FIG. 8 has been changed insofar as the two key magnets 12 are provided in the key 3 instead of three times, they are restored as before. Although it is not equipped with a magnet, it is magnetized throughout its entire thickness, similar to the rotor magnet 5. This effect forms a single continuous magnetic circle closed on the key magnet 12 and the rotor magnet 5 surrounding it on both sides, as shown in FIG. As can be seen, the thickness of the key 3 and the width of the key channel 10 accommodating the key at the same time are much smaller than with the known lock insert in the cylinder lock of FIG. The thickness of the walls on both sides of the channel IO can be reduced. In this way, even if a rough and strong mismatched body is forced into the key channel 10, a much stronger magnetic field is created than before, in part due to the reasons mentioned at the outset, so that the closure and It improves the clarity of the opening and at the same time provides a safe structure.

In the magnetization process, the rotor magnet 5 and the key magnet 12 are assigned an angular pitch of 11°, and the rotor magnet 5 can be encoded in 33 different ways within the 3 key nests, for a total of 33' =3
5,937 variations can be obtained. As already mentioned, by changing the shape of the respective key channel 10 of every key, more than 150,000 different variations are obtained and can be adapted to all requirements.
