Castle in composite construction

The invention relates to an improved lock and in particular on a lock that has both pin tumblers and magnetic tumblers.

There are many different types of magnetic tumbler locks. At their best, these are Magnetic locks are relatively secure and difficult to pick. It is far more difficult to find a lock to break open with a magnetically operated pin tumbler as a lock, in which the pin tumbler in the usual way is under spring pressure. Nevertheless, such magnetic locks can also be picked. One way to do this lies in the use of a master key that has openings that can accommodate and hold the key magnets, so that one can see the various combinations of the key assemblage polarities can play through. Each combination is then tried out in the lock until that combination is found at which the lock opens. A lock with four magnetically operated pin tumblers can be opened of the lock, at most sixteen and on average eight combinations are required. With a magnetic lock, with If the structure is more complicated, this opening attempt will be supported by the use of a small magnetic probe. This probe is used to determine the position and perhaps also the polarity of the various magnetically operated pin tumblers. In either case, ways are known to also

magnetic locks to open. 1918969

Increasing the number of tumblers in a lock with pin tumblers or a lock with magnetic tumblers increases security. However, these changes only increase the time and effort it takes to become unauthorized open such a lock must apply. With the However, the number of tumblers increases the size, cost and complexity of the lock quite considerably. the increased security is thus raised at an expense Size and complexity bought at the price. The achievable security is thus set narrow limits.

There are many improvements in locks with magnetic tumblers as well as in common locks with pin tumblers given that have increased security. The basic technology for unauthorized opening of such locks has become but not changed.

The invention thus aims at a lock that is comparable to Locks with tumblers, which are operated either by springs or magnets, are much larger Security.

The area of application for many locks, especially for Mortise locks limit their length. The thickness of a door or other similar locking mechanism limits the length of the lock and thus the number of tumblers that can be installed to increase security can.

The present invention thus particularly seeks one Guard lock with increased security that does not exceed a given length.

In particular, with the present invention at a given Number of tumblers an increased security can be achieved.

In particular, all these advantages should be achieved with a lock that is sufficiently simple and inexpensive, so that it has a wide variety of uses.

The lock according to the invention has a number of tumblers which extend radially relative to the main axis of the lock. These tumblers are of two different types: they are spring-loaded pin tumblers and um magnetic pencil holdups, the lock according to the invention takes on a key provided with springs, with at least one spring in the longitudinal direction of the key on the outside of the key runs. The key also has recesses for receiving key magnets with which the magnetic pin-shaped Locking devices are tightened and / or repelled in the open position.

When inserting the key into the one provided for this in the lock Key guide moves the spring to a corresponding set of pin tumblers. With the key fully inserted all pin tumblers have thus been removed from the parting line. Each key mapnet draws one of the Magnetic pin tumblers or pushes them off, so that these too are outside the separating foot and the lock rotated weracm can. This lock according to the invention redeems serious fooling around the entire key industry.

An additional safety element arises from the fact that the tumblers of the two types of construction are different radial positions.

The magnetic tumblers used in the lock according to the invention all work according to the attraction technique the repulsion technique or partly after the attraction and partly according to the repulsion technique,

The combination of magnetic pin tumblers and spring-loaded pin tumblers also brings a downright dramatic increase in the number of usable opening combinations. The one embodiment described below has approx 2o million usable combinations.

Other objects and advantages of the invention will become apparent from the following detailed description and drawings. In the drawing is:

Figure 6 is a section on plane 6-6 of the key shown in Figure 5 with a key inserted. so that the magnetic locking devices are in the unlocked position,

Figure 7 is a broken away view of part of the embodiment shown in Figure 5;

FIG. 3 is a section similar to FIG. 6, through the one shown in FIG 7 embodiment shown, with the key withdrawn is, so that the magnetic locking devices are in the locked position and

FIGS. 9 a and 9 b are sections similar to FIG. 6 of the embodiment shown in FIG. 5, the magnetic interaction between the key magnets and the tumbler magnets after the repulsion and not after the attraction technique takes place.

The lock shown in Figure 1 includes three coaxial cylindrical members, each of which is made of non-magnetic material. The inner link is the cylinder 18, the middle link is the lock body 2o and the outer link forms a jacket 22. The cylinder 18 is rotatable in the lock body 2o so that it rotates when locking and when unlocking in this. A generally cylindrical keyway 24, which has grooves for receiving the key bits, is located therein Cylinder 18 and takes the key 25.

I-ieun guides 26, six of which are shown, extend in the cylinder 18 radially through the lock body 2o and η Ehr.en nine spring-loaded tumbler pins 28. These a total of nine guides 26 are arranged in groups of three each. Each group lies in a particular radial i-bene, which passes through the longitudinal axis of the lock body 2o «

In addition, each guide 26 is in a different cross-sectional plane, The nine tumbler pins 28 are thus offset from one another in the longitudinal direction. When rotating the Cylinder 18 in the lock body 2o can thus none of the tumbler pins 28 fall into a guide 26 of another tumbler pin and thus block the lock,

Each spring-loaded tumbler pin 28 has an inner section 28a, an outer section 28b and a peder section 28 s on. When the key is inserted into the lock, the tumbler pins 28 are displaced radially so that the parting plane between the inner section 28 a and the outer section 28 b forms an extension of the parting line 32 of the lock (see Figures 2 and 3) · The parting line 32 is the contact surface between the lock body 2o and the cylinder 18. The radially outer ends of the spring portions 28c rest on the inner surface of the jacket 22 so that they are always under Standing under pressure.

In addition to the nine spring-loaded tumbler pins 28, the embodiment shown in FIG. 1 also has three hag tumbler tumblers 3k. Three guides 36 run in the cylinder 18 radially outwards into the lock body 2o and take these three magnet tumblers 3 ¹ I on. The guides 36, as shown in Figure 1, are not only offset from one another in the longitudinal direction of the lock, but also in the circumferential direction by 120 ° in each case 26 for the tumbler pins 28 offset.

A spacer 38 made of a non-magnetic material is arranged at the radially outer end of each guide 3.6. These spacers separate the! -! Agnetzuhaltungen 3 ² I from an insert Ho , which consists of magnetizable material.

The key 25, which actuates the spring-loaded tumbler pins and the Magnetzulialtungen 34, has a cylindrical Shank 41 and three beards 42 on. The beards 42 lie in the circumferential direction apart by 12o degrees. Two whiskers 42 can be seen in FIG. Each beard 42 has incisions 44, with which the corresponding tumbler pins 28 are raised to the height required to unlock the lock. In addition, the key 25 has three in its shaft 41 Bar magnets 46 on. In the axial as well as in the angular direction, these magnets have a certain position so that they the Actuate three magnetic locking devices 34 and up to one side the parting line 32 can move so that the lock lets open.

The following can be seen in FIGS. 2 and 3: As soon as the key 25 is inserted into the key channel 24, are the various cuts 44 the corresponding * tumbler pins opposite, so that the inner portions 28a and the outer sections 28b of each tumbler pin 28 be aligned with the parting line 32. In addition, each bar magnet 46 pulls a magnetic lock 34 radially inward, so that they leave the parting line 32 and the cylinder 18 can be rotated in the lock body. In the embodiment shown, magnetic attraction is used. this lsi individual means that each bar magnet 46 has such a polarity that it has the corresponding magnet lock 34 attracts.

When the key 25 is removed, the magnetic lock is activated through the magnetizable insert 4ο in a radial outer position pulled so that it then locked the cylinder 18 in the lock body 2o. To perform this function it is not necessary, that it is made of a magnetizable material b estehence "insert ho is itself magnetized because the "ar-net ^ uaaltair- 3" by itself to each one lying next to her Magnetized are materials, such as: For example, iron attracts. Of course, the insert 4o could also be designed as a liagnet will. In this case, the cord pole of the mission 4o, v: ie at aer. in 7ir: ur 2 ^ ezei.rten example, lying radially inside,

so that the magnetic lock 34 is attracted. Definitely the dimensions and the relative strength of the magnetic field must be dimensioned so that the bar magnet 46 when inserted Key 25 overcomes any force of attraction that exists between the magnetic locking device 34 and the insert 4o, to move the magnet lock 34 radially inward. Of the non-magnetic spacer 38 is essential for a proper one Balance between magnetic forces. Otherwise the approach of the insert 4o would be to the magnetic lock 34 so large in the unlocked position that it is impossible for any magnet embedded in the key 25 would be to overcome the strong pull that would arise when the insert 4o and the magnetic lock 34 would stick to each other.

When this magnetic effect is used, obviously neither the cylinder 18 nor the lock body 2o should be made of magnetizable material Material.

In the embodiment shown in FIG. 1, there is a shift the magnetic guard 34 in their leadership .36 magnetic Attraction used. One or more of the magnetic locks However, 34 could also be actuated by magnetic repulsion, as in U.S. Patent 3,111,834 is described.

The embodiment shown in Figure 1 not only offers the highest level of security, but also a large number of combinations. Accordingly, a key with three bits is shown, which enables the use of nine spring-loaded tumblers. If a smaller number of key combinations is permitted, the number of beards can also be reduced.

In the embodiment shown with three beards, each around 12o ° apart, an identification mark must be provided so that the key user can recognize in which

Position of the key 25 Inserted into the keyhole can be. For this purpose, a slot 49 is provided in the key channel 24, into which a pin 5o engages.

When the key 25 is inserted, the cylinder 18 can be rotated in order to use the lock shown in FIG with the locks that are customary today, in which egg bolts are offset from the center line of the lock is, the lock contains a transmission of gears 52 and 54, with which the rotation of the pin to the offset Bolt is transmitted. The embodiment shown in Figure 1, with maximum security a maximum Number of combinations should result, however, that the various spring-loaded tumbler pins 28 and the Liagnezuhaltungen 34 in the circumferential direction against each other are offset. Therefore, the cylinder 18 must be znetrisch in the; Lock body 2o lie.

Figure 4 shows an exploded view of the structure of the key 25. It can be seen that the shaft 4l in essentially consists of two parts. It is an outer tubular dumbbell 4l a and an inner one Cylinder 4l b. In the cylinder 4l b are three bores 56, which accommodate the bar magnets 46. The bar magnets are 46 s held by the jacket 4l a as soon as it is pushed onto the cylinder 41 b. The guide pin 5o holds the jacket 4l a and the cylinder 4l b together.

Embodiment according to FIG. 5.

Figures 5 to 7 show a second and somewhat simplified Embodiment according to the invention. This second embodiment enables the use of numerous standard lock parts and is particularly suitable for a simple structure that is used in Usual locking devices can be installed.

This second is just like the first embodiment Embodiment utilizes the advantage that the combination

from mechanically operated tumbler pins and from Ilagnetz tumblers offers practically unsolvable problems in a single cylinder lock for breaking the lock. When designating the parts of the second embodiment are In the following, the same reference symbols are used as in the first embodiment, as far as this is possible. So are · the last two digits of the reference number 18 for the cylinder, identical to the embodiment shown in FIG with the last two digits of the reference numeral 118 for the cylinder of the second embodiment.

Figures 5 and 6 show the eccentric arrangement of the Cylinder 118 in the lock body 12o, as is common practice. As a result, the key 125 has only one beard 1 * 12. There is also only one group of tumbler pins 128. The tumbler pins 128 movements all occur in a single plane. Four of the five spring-loaded tumbler pins 128 are of the familiar mushroom shape. this makes it difficult to press the lock when a torque is applied to the cylinder 118, since the lip 129 of one or more of the mushroom tumbler pins 128 can be caught by the shoulder attached to the Parting line 132 forms. One of the spring loaded tumbler pins 128 'is a smooth cylinder that does the alignment between the cylinder 113 and the lock body 12o ensures.

Since the key channel 124 and the cylinder 118 in the lock body 12o are offset, a conventional actuating mechanism 158 can be used to displace the pin. The details of this actuation mechanism 158 are shown Not shown.

Four Hagnetzuhaltungen 13 ¹ J are provided, one of which is visible in Figure 6, in the cylinder II8 they are in a horizontal plane. Each magnetic tumbler 134 lies in a guide I36, so that the tumblers in their longitudinal direction

_ _lo _ 909845/0055 bathroom

shifted v / earth. The guides 136 are oriented such that each magnetic tumbler 13 ¹ J moves along a line which is perpendicular to the plane of the beard 142 and thus perpendicular to the line of movement of the spring-loaded tumbler pins 128. As a result of this arrangement of the line of movement of the magnetic locking devices 134, the shaft of the key 145 does not need to have a circular cross-section, as was the case with the key 25 of the embodiment according to FIG.

In the embodiment according to FIG. 5, all of the magnetic locking devices 134 operate with magnetic attraction. When the key 125 is inserted into the keyway 124, each bar magnet 146 will therefore attract a magnetic lock 134 into a radially inner position, the magnetic lock 134 leaving the joint 132 between the cylinder 118 and the lock body 12o. The guide 136, in each of which a magnetic lock 134 is displaceable, extends from inside the cylinder 118 into the lock body 12o. When the key 125 is pulled out, each magnetic lock 134 moves under the action of magnetic attraction between it and the insert Iho ! Haterial in their:. 'Ülirun, ^ l'i'l radially outwards. Of course, a spacer 13c must be made of non-magnetic. Material between the magnetic insert 1.4ο and the Ilagnetzu hold 134 are. The reasons are the same as in the embodiment according to FIG. 1. It must be ensured that the force of attraction in the locked position can be overcome by the bar mass, so that the lock can be opened.

In one preferred for this second embodiment Construction, the latch locks 134 are alternately on arranged on both sides of the key channel 124. As a result, the Ilagnetsuhaltungen 134 are not mutually exclusive influence. Lin advantage of this reduction of a magnetic mutual influence between the magnetic locks consists in a reduction in sliding friction when these tumblers 134 move in their guides 136.

L CH / '- i .. -U-

909845/0055

BATH

This reduction in sliding friction ensures safe operation under the attraction of the bar magnets 146.

Figure 5 shows that the magnetic locks 134 in other transverse cutting planes such as the spring-loaded tumbler pins lie. This ensures that the tumbler pins 128 during a rotation and unlocking of the cylinder 118 in the lock body 12o not in the guides 136 of the magnetic locking devices 13 ^ fall into it.

As has already been stated, the lock body 12o and the cylinder 118 in the embodiment according to FIG. 5 have the usual mutual position. Therefore, there is not enough space to accommodate magnetic locking devices 134, which are approximately 3 mm long, in all radial positions Such an arrangement also facilitates the use of a flat key 125. Its thickness is just sufficient to accommodate the approximately 3 mm long bar magnets 146.

FIGS. 7 and 8 show a modification of that shown in FIG embodiment shown.

A standard technique for making the lock body 12o is compressing P.etallpittffer. It's general It is known that this technique can only be used to form bores and channels in a single direction. The lock body 12o must be provided with an axial opening for receiving the cylinder 118. The guides 136 for the Magnetic locks 134 and for holding the spacers and the inserts 14o would normally have to be drilled after the lock body has been manufactured. The one in the figures The embodiment shown in FIGS. 7 and 8 offers certain manufacturing advantages. Figure 7 shows that two axial channels 16o, one channel on each side of the key channel 124, in the lock body

are molded, rods 14ο ¹ made of magnetizable material are pushed into these axial channels and form the magnetizable material with which the magnetic locking devices 13 ^ are pulled into the radial outer position (see Figure 8) as soon as the key 125 has been removed »

In addition, the small piece of the guides 136, which must be open and extend into the lock body 12o, can be replaced by two grooves Iö2, which run axially on both sides of the key channel along the parting line 132. In one embodiment, the hats are 7 mm deep and provide sufficient depth for the 3 mm long magnetic locking devices 134 to lock the cylinder 118 with the lock body 12o when the magnetic locking devices 134 are in their radially outer position. The axial KariSle I6o and the axial grooves 162 make it superfluous to drill radial bores into the lock body 12o in order to receive the magnetic locking devices 13 * 1 or the magnetizable inserts 14o. But still for the feäerbelasteten tumbler 128 have yet radial "ohrungen be drilled into the SchlÖßkörper 12o. The required with eggs embodiment of FIG 5 spacer 13 ^ of non-magnetic material is bed the embodiment of FIG 7 to the portion of Schloßkorpers 12o, ier to is located between the axial grooves 162 and the axial 1 · 6ο.

In the embodiment according to FIG. 9, the same or similar characters are used as in the embodiment according to FIGS. 5 and 6. The only difference between these two embodiments is that in Figure 5 is iüarnetische attraction and magnetic repulsion FIG ζ used.

ei Fftir 9 a, the key has been removed from the key channel 124 so that the magnet locks 134 a and 134 b are in the locked position. In this embodiment, in which the mechanical repulsion is used for locking and unlocking, two magnetic locking devices 134 a and 134 b are used instead of the single magnetic locking device 134 of the embodiment according to FIG. The main reason for using two magnetic locking devices is to keep the shifting of the magnetic locking devices to a minimum, e.g. L. o, l mm in one embodiment. Such a slight shift in the

tumblers are preferred because they never move far from the magnetic field that causes them to change state. The importance of a relatively small displacement of the magnetic locking devices also applies to the embodiment according to FIG. 5, which uses magnetic attraction, which is also used in FIG. 9 in which magnetic repulsion is used.

Appropriately, the magnet locking devices 134 are as close as possibly arranged on the keyway 124, so that the bar magnets l46 do not have to generate excessively large magnetic fields. Therefore, the radially inner segment 134 a of the magnet ei) of the embodiment shown in Figure 9 must be relatively long be. When the key is inserted into the key channel, the magnetic locking devices 134 and 134b become a short distance (much less than the length of the inner segment 134 a of the magnetic locking devices) pushed into a radial outer position. In this radial outer position, the parting line is between the two magnetic locking devices 134 a and 134 b with the parting line 132 between the lock body 12o and the cylinder 118 aligned. The lock can thus be completely outside without moving the magnetic locking devices 134 into a position. of the cylinder 118 are opened.

In addition to the use of two magnetic locks 134 a and 134 b it is important to know that an auxiliary magnet l4o a instead of the insert I4o made of magnetizable material is used *

L 64/4 _B £ _D ORIGINAL ^ ₁ H *.

909845/0055

When using magnetic repulsion, the auxiliary magnet is used 14o a required to bring the lock according to Figure 9 into the locked state. As Figure 9 shows, butts the auxiliary magnet l4o a the magnetic tumblers 134a and 134 b into a radial internal pitch. Bridged in this inner position the Magnetzuhaltung'134 b the parting line 132 and thus brings the lock into the locking position.

So it is actually the Ilagnet 134 b, its position determines the state of the lock. It should be noted that the reference to a magnetic lock is in relates the broad claims to this magnetic lock 134b.

In connection with the embodiment according to FIG. 5, it should be noted, which also applies to the embodiment according to FIG acts so that they reach into the single common key channel 24, 1P4. Thus, not only a single cylinder 18, ll'l and a lock body 2o, 12o all r.it resulting Vortc-ilen affected, but from the standpoint ^r lev security is vielt r.ehr the only key channel 24, 124, which it difficult! ;; avenge.

Another un.l very v.'ichti-rer reason why this lock in composite construction offers maximum security is that even when the spring-loaded Cuhaltunrrsstifte 23 and 12'- unlocked and the "acnetzuhaltungen 34 and 134 become ineffective be .iacht könna ^ of viichtige fact kor.r the impact: .t that the necessary internal procedures genenseitif: extinguish the * ~ AuPt around for this is that the ¥ federtelasteten Zuhaltunrsstifte 28, 12S are unlocked tore while.. a torque has to be applied to the cylinder, while the magnetic locking devices 34 and 134 can only be made irreversibly before the turning

nonent is applied to the cylinder. The magnetic locks are actuated by radial forces which, compared to the radial forces, are required to unlock the tumbler pins are relatively small. Therefore, if a torque "relative to the lock body" is applied to the cylinder there is a very high probability that one or more of the ITagnet locks in the V are locked Position against the wall of their guides 36, I36 are pressed, sufficient friction arises so that even if the correct key is inserted, the magnetic forces are insufficient would to move the magnetic locks against the frictional force. The torque is reduced so that the ITagnet locks can move, the jump spring-loaded tumbler pins back into their locking position. This makes the opening of the inventive Castle extremely difficult. There is thus an extremely secure lock of relatively simple construction and at a cost that is disproportionate in comparison with the required security.

From the above it follows that the objects of the invention by Application of. spring-loaded tumbler pins as well as iJagnetz tumbler, both of which are released by can be operated from a common key channel. This means that only one key is required, the one Has notched beard and inserted bar magnets. That However, breaking such a lock requires the simultaneous detection and actuation of both the spring-loaded ones Tumbler pins as well as the ilagnet tumblers. Since this requires two completely different techniques that must be carried out at the same time, namely be effected from a single key channel, and since these two techniques interfere with each other, the result is a lock that is really unbreakable.
