DE19547410A1 - Encodable cylinder lock with key - Google Patents

Abstract

The lock comprises a cylinder housing with spring-located housing pins axially one behind other in it. The housing pins press up on a cylinder core located in the housing, preventing a key which does not fit from turning. Each housing pin is in three parts with stretched diagonal cuts (A) with a hexagonal axis and corresponding structure platelets. The housing pins (A,B) can have a shrunken form (A1,B1). An encoding unit comprises a two-part core pin with a bracing spring set and a cylindrical axis firmly pressed into the upper part of the core pin.

Description

The invention relates to a locking cylinder associated key, which is usually used to secure property is used. And thus already a commercially available Lock cylinder good service in the area of home as well as in Trade to lock the doors.

As long as all keys are complete, there is no risk that the security provided by the cylinder lock on is diminished in any way.

So there are doubts about the security of the cylinder lock only when an associated key is lost. Key users can be stolen by, too personal documents including the address in the hands of the thief come, which have fatal consequences for security of property could.

If this happens in the private sphere, it is often, actually almost always, self-help is not possible and therefore only remains this one choice that the cylinder lock from a professional is replaced, which inevitably involves costs is.

If damage is caused by a lost key, it’s often difficult to get help from Specialist can not be done in time.

Basically, a chain reaction arises, which is also a Avalanche of costs can result.

In the commercial area of door security, the problem is over so bigger by using the user key in different ways can get lost.

This is due to theft, keys not handed in Change of staff or incomplete number of keys Tenant changes, to name just a few examples.

In all of these cases security suffers and therefore always is Property in danger.

When purchasing a locking cylinder, you also acquire keys the associated lock in the cylinder lock.

Even if you buy system locking cylinders, you only acquire those current keys that belong to this system.

As a result, key losses are almost always associated with the fact that Cylinder locks or even entire systems renewed prematurely will.

The object of the present invention is to provide familiar security protect, but to the user or insurance provider from costs protect and give the user an opportunity help themselves free of charge and independent of time.

The object of the present invention is also in Lock system area. To be able to design the locking system that the mechanical switching elements that come from electrical engineering perform known functions AND OR, as a lock switch or even locking system redesign, but with those from the Electrical engineering known ON FROM CHANGE TWO WAY and CROSS  Perform functions without more space or even additional To take components in the cylinder locks.

This task is solved by the characteristics of the marked Part of claim 1.

Convertible cylinder locks are well known and are characterized in that conversion of a closure with various additional components that run but at the moment of industrial manufacturing, something else are difficult, such as G 295 08 840.0.

In G 94 20 332.6. movable axes are recognizable and known, however, moving the axes is extremely difficult to realize industrially.

DE 30 48 222 C2 switchable lock cylinder is known, but that the function of adjacent permanent magnets is extremely questionable and to the detriment of the function, the additional cylinder lock ( 25 ) of the cylinder lock ( 24 ) in Fig. 19 as a higher-level function carrier with the general lock actually completed. Cylinder locks are also known, in that a lock changeover can only be achieved by destroying the previous lock. This means that such a destruction of the lock cannot be restored and consequently such a cylinder lock can only be used to a limited extent. Furthermore, even during the manufacturing process of these cylinder locks, it is not possible to check these next functions, since the lock would have been destroyed already then.

A change in the closure, actually by the non-specialist is not known.

Due to the inventive design of the codable Cylinder lock according to claim 1 exist after each Key loss the existing security features a cylinder lock, in which the closing height on the one hand can be moved to another level or on the other hand Lock parts of the existing lock mechanically switched off or switched.

It is to be understood that one key is the six incisions has an information carrier that per key cut carries at least one piece of information.

The invention and presented according to claim 1 Cylinder lock carries both core pins as well Housing pins, which in connection with mounting plates several Can carry information per tumbler pair. Under a pair of tumblers there always belongs a core pin and a Housing pin as well as at least one build-up plate. And these three building elements are also called three Individual information evaluated.

And information can be both a certain form of Core pin as well as the closing height or Depth of cut at the key.

As a result, the core pin consists of two pieces of information. Information one is when core pin is shrunk is twisted.  

Information two is when this same core pin is stretched out Shape is twisted.

And the information three is when the build up tile with the help of the housing pin is released from the holding axis. And so according to the invention after each key loss Information in the cylinder lock changed when removed, that is, the previous information is blocked, and one new information is released.

Then the key with the locked function in Cylinder lock can no longer be recognized and consequently a rotation of the cylinder core is denied with certainty. A completed conversion can of course be reversed at any time be made.

As a result of the design of a locking system according to the invention with features according to the main claim Key loss both low-value and higher-value yes even main closure with the mechanical switching functions ON FROM CHANGE TWO WAY and CROSS convertible to another Level of closure by adding number of levels of closure in Relationship of the build-up tiles used per Closing channel depends.

Locking element 35 as a snap ring, which is firmly clamped on the axis, but the axis can nevertheless be moved into the mounting plate 7 . Three-part housing pin shown in Figure (B) with elastic clamping rings 36 which allow the axis to be displaced in the direction of the mounting plate 7 .

Housing pin shown in Figure (C) is constructed from two sleeves 40 and 38 , which have diagonal cuts 39 . Elastic bushing is pressed into the sleeves, and is also pressed into the cylindrical axis, which protrudes into the build-up plate 7 .

Fig. 13: Figure (A) shows a three-stage core pin, in which the steps are held by the elastic bushings, but which allow a stepless and step-like displacement of the individual steps.

Figure (B) shows a two-stage core pin, the same Has properties like the illustration (A). Figure (C) shows the different height effects in one stepless displacement of the core pin (B) relative to one Key cut.

Fig. 14 shows core pins (A, B, C) with differently designed bottoms with Umschalaufaufplätchen and each associated housing pin as a closing switching element. (X1 and X2) show the switching differences, the amount of which depends on the design of the core pin bases and the difference in the jump of the buildup plates 7 used .

As can be seen in FIG. 2, core pin 10 forms the basic closure.

The basic lock and mounting plate 7 together form a user lock. Drawings (A) and (B) are to be viewed in this way if the user key is inserted in both drawings (A) and (B). Figure (A) shows the housing pin shown according to the main claim, which is stretched and that the axis 4 is immersed in the area of the housing pin. This means that the mounting plate is free and the cylinder core can twist with the user key.

The user key is switched off by stopping the upper part 5 of the housing pin, which is secured against rotation, through the changeover opening 9 . Through the changeover opening 9 a, the lower part 2 of the housing pin is rotated by 180 ° with the aid of a screwdriver and thus the housing pin is shrunk and the axis 4 now looks out of the housing pin by the changed length of the housing pin. This looking-out part of axis 4 now plunges into the mounting plate provided with a hole.

Figure (B) shows the clear impact of the deactivated user lock. Basically, an elongated housing pin is just as long as a shrunk housing pin with the mounting plate. As a result, user access no longer exists. Only the basic lock 10 remains and, as previously mentioned, the user key in the illustration (B) is inserted in the cylinder lock, but turning the user lock off means that the cylinder core can no longer be turned. The housing pin itself consists of two capillary sleeve parts, in the lower part 2 has diagonal sections of 5/5 and in the upper part 5 has two diagonal sections, in which one section has 1/5 and the other diagonal section 4/5. The stretched position was achieved by the 1/5 diagonal cut and the cut itself prevented independent twisting, since the spring pressure 8 pressed both cut shapes from the lower part 2 and the upper part 5 together. Even if the elongated form is twisted into the shrunk form, it should be noted that a little stretching is first carried out before the upper part 5 can slide downward on the 5/5 slope into the shrunk form. Since a basic lock is available in this example, this principle can also be used well in the plant area.

As can be seen in FIG. 4, the illustrations are shown with a switchable core pin. Figure (A) shows elongated core pin designed according to the main claim. The user lock now corresponds to the height of the core pin. Key with this lock can thus turn the cylinder core. The switch closure is now performed so that the upper part 12 is held of the core pin by the Umstellöffnung 14 and through the Umstellöffnung 14 a and by the spring and by the housing pin, which consists of a capillary tube, the lower part 11 of the core pin with a screwdriver, which is expandable and known from electrical engineering, firmly clamped and tightened downwards against spring pressure. The axis 3 is pulled out of the upper part 12 of the core pin and rotated by 180 ° and then pushed back into the upper part 12 of the core pin. This results in a shrunk state of the core pin, as shown in Figure (B). It can be clearly seen that the housing pin has taken up the shrunk length of the core pin and the key with the locking of the illustration (A) is switched off in function and cannot cause the cylinder core to twist. Axis 3 is polygonal and consequently tap changers can be implemented OR by using a single core pin that can be switched up to 8 times. The angle of the diagonal cut can be freely selected from 5 ° -80 ° and is responsible for the height of the different jumps.

As shown in Fig. 6 according to the main claim, a spring-loaded core pin 17 forms a mounting plate 7 and the housing pin 16 a mechanical changeover switch. Housing pin consists of a capillary tube sleeve with a pressed-in elastic bush 16 a is pressed in the axis 15 and protrudes into the mounting plate 7 according to the illustration. The axis 15 a is firmly anchored in the upper part of the two-part core pin and the two-part core pin is pressed apart by the springs. The spring pressure is at least 10 times higher than that of the housing pin spring. Change of closure is carried out as follows. When the key is inserted, the housing pin is pressed against the inserted key through the changeover opening on the cylinder lock. In this process, the core pin is pressed together and the axis 15 a exerts a counterpressure on the axis 15 . And thus the axis 15 is pushed into the housing pin by mounting plate 7 and when removing the change tool, the core pin returns to its original shape and the mounting plate is released. There is a basic locking of the core pin and a user locking, which is formed from the basic locking and from the size of the build-up plate used. You can now switch back and forth between the basic lock and the user lock. To get back to the basic closure, as the sole closure, only the axis 15 has to be pushed up to the axis 15 a.

And so the user lock is instantly on the Basic locking switched and the key with the User locking is therefore without function.

This form of switching access authorizations can easily can also be carried out by a non-specialist.

Since cylinder locks are used in different areas, can also choose different forms of switching elements be that optimal security and flexibility of the Cylinder lock is achieved by solving the task Main claim and sub-claims is very large. How from Figure representations are the main features documented in detail.

The codable cylinder lock offers main advantages in that the built-in switching elements only by Moving the axis triggers functions that counter lock can control, compared to the known convertible Cylinder locks, in which individual parts of the components used have to be transported or even removed. By doing then the original conditions are difficult or no longer at all can be achieved. Fiddling is therefore only for the experienced Expert possible. The codeable offers further advantages Cylinder lock in the outdoor area of applicability. Through the Changeover openings can no longer form a condensation in the cylinder lock occur. Thus, the housing springs have a longer life Experienced. A blockage from the many graphite powder can also belong to the past because of the openings mentioned or less self-cleaning is performed.

In the commercially available cylinder locks can be changed become standard, giving retailers some new perspectives be opened.

Pre-assembled cylinder locks can be opened without for the construction of groups with the same key or for the construction of Locking systems are used. Even the non-specialist is after a short instruction, able to realize ideas that are simply reserved for industry today. To switch elements according to the main claim in the cylinder lock to use does not take up more space than it currently does to Cylinder locks with multiple functions to manufacture, which in Difference to the current state of technology for the user can be an enormous cost factor. The security itself is thus increased a lot. Although cylinder lock with multiple functions is equipped and by key functions unproblematic ON and OFF or toggled is always only the current one Closure present in the cylinder. It is compared to one Locking cylinder with a single lock for security reasons equate, but if necessary to another  Access authorization is switchable. That is considered essential Considered an advantage over the current state of the art.

Depending on the size of the mechanical switching elements, there are more Applications in the field of mortise locks, such as can be seen in the area of mechanical coding keyboards. There were Considerations awake, a cylinder lock with keypad too realize, because then an actuation of the cylinder core with Enabling the coding keyboard could be done.

Configurability of the closures with a TAST function is also considered, in that, as in FIG. 14, shapes in the base region of the core pins are designed in such a way that, as can be seen in FIG Functions with an interaction are allowed, whereby a basic closure is simply extended by the mounting plate 7 or can be released again by tapping on it. The build-up tile and the jump are switched off.

The executive function is roughly the function of a Equate ballpoint pen. There too is unique Tap the refill from the pen housing pushed out and the tap dips again back into the ballpoint pen housing. That is also a Comparison and at the same time a confirmation of the functionality of the mechanical switching elements designed according to the main claim. A independent conversion cannot be carried out. The task solution includes 14 sheets of drawings.
