The locking bars are displaceable in an axial position by an appropriately coded key until each pin (15) is directed towards a respective combination hole. Turning the key causes the rotor assembly (17) to rotate. At various rotational positions, the locking bars are displaced radially causing the pins (15) to engage their respective combination holes. The combination post (12) can be provided with parallel combination holes. Furthermore, the combination post (12) can be removable in order to replace the combination post (12) with another post having different combination values, thereby changing the combination of the lock.

Description

Rotary lock and key

technical field

The present invention relates to an improved lock structure and key as well as an improved master keying method and combination changing method.

Background technique

Lock constructions, especially for high security locks, have a tendency to include increasingly complex mechanisms to achieve higher levels of security. A corollary of such complexity is that lock mechanisms include more moving parts to enable more combinations. In order to re-key a lock, thereby changing the combination of the lock, it is necessary to disassemble the lock, adjust or replace essential elements of the lock, and then reassemble the lock. This process is complex and time-consuming, and requires the skill of a professional locksmith.

The robustness of the lock is another consideration when providing a lock in which the combination will change frequently. This is often the case with high security locks. Lock manufacturers have produced locks for this purpose where only part of the lock construction has to be removed and rekeyed to provide new combinations. Typically, what is removed, rekeyed and then replaced is the lock plug. However, rekeying the lock plug still requires disassembly and reassembly of the lock plug and remains a very complicated and time consuming process. The process of removing and replacing such lock plugs is not straightforward. The lock must be designed such that the process of removing and replacing the lock plug is relatively quick and efficient. Both the lock structure and the removable parts that will not be removed must be able to withstand the removal and replacement process; any damage incurred during this process may necessitate replacement of the entire lock. Special care must be taken to ensure that the removable portion is properly aligned so that it is in proper working engagement with the rest of the lock structure. This is no ordinary job and requires a high degree of precision. Thus, frequently changing lock combinations can constitute an expensive and laborious operation. In the high security lock industry it has been desired to be able to provide master key control. The master key control includes the level of the key. The number of locks that a key can open depends on the level of the key. Typically, the classes include standard keys, which open specific locks; master keys, which open multiple locks; and grandmaster keys, which open all or nearly all locks.

In Matt Blaze's paper "Cryptology and Physical Security: Rights Amplification in Master-Keyed Mechanical Locks" IEEE Security and Privacy (March/April 2003), the inherent issues associated with master-key control are discussed. Overall, master key control actually reduces the number of possible combinations that can be applied to the lock. This reduces the security that such locks can provide. It has been noted that, in the case of implementing master key control by configuring its profile, it is also possible to reduce the strength of the key, resulting in operational difficulties.

Accordingly, it is an object of the present invention to provide a lock construction which provides a reasonable level of security and robustness.

A further preferred object of the invention for such locks is to facilitate changing combinations, wherein a minimum number of moving parts needs to be replaced. Compared with other locks, the combination changing process will be relatively simple.

A further object of the present invention is to provide a key suitable for the lock of the present invention.

It is a further preferred object of the present invention to provide a lock which provides improved master key control capability, wherein the master key control does not substantially reduce the number of available operating combinations.

Contents of the invention

According to one aspect of the present invention, a cylinder lock is provided, comprising:

a housing having a cylindrical bore therein;

a rotor assembly rotatably mounted in the bore;

a plurality of locking levers disposed on the rotor assembly, each locking lever comprising a locking lever pin radially inward toward the axis of the rotor assembly, wherein each locking lever is movable on the rotor in a direction substantially parallel to the axis assembly, and each locking lever is movable in a radial direction relative to said axis; and

a composite rod disposed along the axis, the composite rod having a plurality of composite holes formed therein;

Wherein in said substantially parallel direction, each said locking lever is adapted to be moved by a coded key to a position where the locking lever pin of each said locking lever faces the corresponding combination hole; said rotor assembly is adapted to be moved by said key rotate to an unlocked position, wherein in each rotational position, each of said locking levers is moved radially toward said axis to engage each of said locking lever pins with a corresponding combination hole to allow said rotor assembly to be seated in said hole rotate.

According to another aspect of the present invention, a cylinder lock is provided, comprising:

a housing having a cylindrical bore therein;

a rotor assembly rotatably mounted in the bore; and

a plurality of locking levers disposed on the rotor assembly, each locking lever comprising a locking lever pin radially inward toward the axis of the rotor assembly, wherein each locking lever is movable in a direction substantially parallel to the axis the rotor assembly is movable, and each locking rod is movable in a radial direction relative to said axis;

Preferably, the lock combination can be changed by merely replacing the combination lever. The positioning of the combination hole on the combination rod provides the lock combination. Thus, the lock combination can be effectively changed by replacing the combination lever with another combination lever having the combination hole in a different position. In this way, the replacement process is relatively simple and involves almost a minimum of moving parts. The most complex moving part is the locking lever, which does not need to be replaced or adjusted.

According to another preferred aspect, the present invention relates to a key and combination lever set, comprising one or more combination levers and one or more corresponding keys, whereby if a lock is set by said lever or levers determined combination, the key or keys can operate the lock.

Preferably, the lock provides optional parallel combinations. This means that a lock can be operated by multiple keys, providing master key control capability, but with the advantage of not reducing the number of available combinations.

According to another aspect, the invention relates to a key for a cylinder lock,

The lock includes a housing having a cylindrical bore therein; and a rotor assembly mounted in the bore, the rotor assembly including locking bars disposed radially about the rotor, each of the locking bars being arranged to move substantially moving in a direction parallel to the rotor axis,

The key includes a body with a cylindrical bore, and a set of radially disposed outward projections operably adapted to move the locking lever.

In a preferred form, the key further includes means for engaging a combination lever of said lock and operable to rotate said lever to a predetermined rotational position.

Detailed ways

1 and 3 show a preferred embodiment of a lock structure according to the invention, comprising a plug 30 and a housing 13 .

The plug 30 includes the combined rod 12 , the surface cover 8 and the rotor assembly 17 .

The rotor assembly 17 receives the combined rod 12 as a core. Guide slots are provided around the periphery of the rotor assembly 17 and extend axially along part of the length of the rotor assembly 17 . Each channel receives a locking bar arranged to slide along the length of the channel. Each locking lever is biased by a spring 18 towards the visor 8 . Each channel also includes a cutout along a portion of the length of the channel. This cutout makes it possible to access the combined rod 12 from the guide slot.

The locking lever comprises a bracket 16 and a head piece 15 . The head piece is provided with a locking lever pin radially towards the combination lever 12 and is biased by a spring 19 in a direction radially away from the combination lever 12 .

The surface cover 8 includes a keyhole, a fixing clip 6 , a fixing pin 10 and a surface cover positioning ball 9 . The visor positioning ball 9 and the fixing pin 10 fix the position of the visor 8 relative to the housing 13 .

An anti-drilling plate 11 is provided between the surface cover 8 and the locking rod as an anti-tampering measure to prevent access to the locking rod from the surface cover 8 . An anti-drill collar 14 is also provided to prevent access to the surface of the composite rod 12 .

Combination lever 12 includes a plurality of combination holes on its surface to provide combination value for the lock. The number of combination holes is usually the same as the number of locking levers provided. The combination holes are arranged at angular positions around the periphery of the combination rod 12 so that at least one combination hole is accessible through respective cutouts of the guide groove. The combination holes are also provided at different axial positions along the length of the combination rod 12 . The range of possible axial positions is controlled by the length of the channel cutout. The axial position of each combination hole determines the combination value of the combination hole. Possible different axial positions 20a-20g of one of the combination holes are shown in Figures 4a and 4b.

The combination rod 12 may be provided with additional 'dummy' holes as an additional tamper-resistant measure.

In order to release the lock, each locking lever pin 15 of the locking lever must engage the combination hole of the combination lever 12 . This is accomplished through the use of a suitably coded key, the preferred embodiment of which is described below.

Referring to Figures 1 and 3, the key includes a code arranged to engage the bracket 16 of the locking lever. When the key is fully inserted into the keyhole, the coding causes each bracket 16 to slide along its guide until each locking lever pin 15 is positioned in its corresponding combination hole. The key also engages the combination lever 12 and the rotor assembly 17 so that rotation of the key rotates the combination lever 12 and the rotor assembly 17 . When the key is turned to the unlocked position, the locking lever is urged radially towards the combination lever 12 and the locking lever pin 15 engages the combination hole. Without using the correct key, one or more locking lever pins 15 will not engage in the combination hole, the corresponding locking levers will not be able to move inwards and the rotor will not be able to turn.

FIG. 2 shows a view along the bore of the housing 13 . The surface of the hole has a plurality of grooves 21 extending along the length of the hole. When a properly coded key turns the rotor, the grooves allow the locking lever to move radially outward while the locking lever pin 15 disengages from the combination hole. Turning the rotor further causes the locking levers to clear the grooves, pushing them radially inwards and engaging the locking lever pins 15 with the combination lever.

In another embodiment of the lock, the combination lever 12 is provided with additional combination holes which are angularly offset from the aforementioned combination holes. This provides at least one optional set of parallel combined values for keys of different encodings. In order to unlock a lock using this optional combination value, the combination lever 12 must be rotated independently of the rotor assembly 17 so that the optional combination hole is accessible through the cutout. It should be appreciated that this alternative embodiment facilitates master key control of the lock. A preferred embodiment of this alternative form of lock will now be described.

Referring to Fig. 4a, the combination lever 12 in this embodiment has three sets of combination values, namely a central set (central set) 20, 22, a left-turn set (left-turn set) offset from the central set in the clockwise direction and a counterclockwise set (left-turn set). A right-turn set offset from the center set in the clockwise direction. In FIG. 3 only one left-handed group combination hole 23 can be seen. Likewise, only one right-handed set of combination holes 24 can be seen. The combination lever 12 also includes a triangular recess (setting hole) 25 .

A set pin 26 is provided on the rotor assembly 17 . The setting pin 26 protrudes into the triangular recess 25 .

The combined rod 12 is rotatable independently of the rotor assembly 17 . The combined rod 12 is further elastically biased in the axial direction. This resilient bias and setting pin 26 causes the combination lever 12 to naturally position itself in a position where the central set of combination values aligns with the cutouts of the guide slots, as shown in Figure 5b. According to the triangular shape of the recess 25, the setting pin 26 guides the combination lever 12 into this natural position, so that it is located at the corner of the triangle. In this position, a key with a code corresponding to the central group combination value will unlock the lock in the manner previously described.

To change the lock to a left-handed combination value, the combination lever 12 is pushed into the lock until the setting pin is positioned at the bottom of the triangular recess, then the combination lever 12 is turned counterclockwise until the setting pin is at the right corner of the depression, as Figure 5a shows. In this position, the combination hole that provides the combination value of the left-handed group is aligned with the cutout of the guide groove. Then, as before, the lock can be unlocked, but with a key having a new available code.

The process of changing the lock to a right-handed combination value is basically the same, except that the combination lever 12 is rotated clockwise, as shown in Figure 5c.

Pushing and rotation of the combination lever 12 is preferably performed by a key. In this case, the face of the combined rod 12 is shaped to engage with the rotator 3 . The orientation of the spinner 3 indicates whether and in what direction the combination lever 12 is initially turned, in order to set the appropriate combination group. Different orientations of the spinner are shown in FIG. 5 .

A preferred embodiment of a key for operating the aforementioned lock is shown in FIG. 1 . The key includes a key head 1, a rotator 3, a fixed pin 5, a fixed sleeve 2, a cylindrical body 4 and a drive rod 7.

The cylindrical body 4 has on its surface a protrusion 4a extending along the axis of the surface. The projections 4a provide a code on the key and are positioned around the periphery of the combination post 4 so that each projection 4a engages with a corresponding bracket 16 of the locking lever. The axial length of each protrusion 4a determines how far the locking bar is moved along the guide slot.

The surface cover 8 is shaped in order to receive the combined column 4 with the protrusion 4a.

The protrusion 4 a and the drive rod 7 interlock with the rotor assembly 17 . This drives the rotor assembly 17 in rotation when the key is turned.

The spinner 3 is arranged in a cylindrical body 4 . The front end of the spinner 3 is shaped to fit the front end of the combined rod 12 . The rotator 3 is arranged relative to the cylindrical body 4 so that, when the key is used, the rotator 3 engages the combination lever 12 before the protrusion 4a has fully moved the locking lever. This allows another set of combined values on the combined lever 12 to be selected before the locking lever is fully moved.

The surface cover 8 is shaped such that the key with the drive lever can only enter and exit the lock in certain orientations. This ensures that the code of the key is correctly aligned with the combination value on the combination lever 12 when the key is inserted and returns the lock to its starting position when the key is removed.

It is conceivable to vary the above-described embodiment in many significant ways. In particular, the combination lever 12 may only be provided with two parallel combination values. It is also contemplated that the combination lever 12 may be provided with more than three parallel combination values. The practical limit on how many parallel combination values to set depends on the angular spacing of the locking levers and thus of the corresponding combination holes of the same group, between which the corresponding parallel combination holes are located. It should be understood that there must be a sufficient degree of spacing between the combination holes of the parallel combination values to provide parallel sets of combination values that are distinct from each other.

This is an important advantage of the lock of the present invention. In conventional constructions, where all keys operate using the same set of possible combinations, say, six pins each with 5 positions, any master key control removes free combinations. In this structure, multiple combinations can indeed be parallelized. A completely different key relative to one rotation can operate on another rotation. Only one rotational position can be active at a time. Additionally, the lock user may not need to understand which alternative positions are in effect.

Thus, the master key combination can be set in a rotational position without any combination relationship or restrictions imposed by conventional combinations.

In the above described embodiment of the key, the protrusion 4a has a continuous length. The coding depends on where along the length of the key the front surface of the projection 4a is located, since it is that part of the projection 4a that engages the locking bar. Thus, the coding aspect of the protrusion 4a can be replaced by a bump, or similarly positioned where the front surface needs to be.

In another preferred embodiment, the combination rod 12 is removable. This allows replacing the combination lever 12, thereby changing the combination of the lock without changing the structure of other parts of the lock. In this embodiment, the combined rod 12 is provided with a groove 27 extending to the rear end of the combined rod 12, see Fig. 4a.

The procedure for removing the combined rod 12 will be described below. Figures 2 and 3 show the initial position of the rotor assembly 17, which corresponds to the position when the key is inserted into or removed from the lock. In this position, the locking lever pin 15 is not engaged with the combination lever and the setting pin 26 is fully engaged in its recess 25 . Rotate the rotor assembly 17 clockwise to the removal position. During rotation, all locking lever pins 15 and setting pins 26 engage their respective combination holes. 6 and 7 show the rotor assembly 17 in a removed position. In this position, only the locking lever 28 and its locking lever pin engaging in the groove 27 are moved radially. The other locking lever pins and the set pin 26 do not engage in their respective holes. The combination lever can then simply be withdrawn straight out of the lock, the locking lever pin of the locking lever 28 following the path of the groove 27 . The composite rod 12 can be extracted by simply gripping the surface of the composite rod with fingers and pulling, or by using a suitable gripping tool.

A removal key 29 is preferably provided to initially position the rotor assembly 17 in the removed position. The removal key 29 is similar to a normal key, but with the drive rod 8 removed. This allows the removal key 29 to be removed from the lock, but retains the rotor assembly 17 in the removed position. The combined rod 12 can then be accessed for removal.

Inserting a replacement sectional rod 7 is basically the reverse of the procedure described above.

Removal key 29 still requires proper coding to turn rotor assembly 17 to the removal position. Typically, this coding will correspond to that of the master key, so that only one removal key 29 is required to act on all locks.

It should be understood that persons wishing to change the combination of their locks need only a new combination lever 12 and an appropriately coded key. It is contemplated that the combination lever and key will be provided in a matching lever and key set. Where there are parallel combinations on rods, multiple matching rod and key sets may be provided with one or more master keys for some or all rods.

As shown in FIG. 8, in another embodiment of the lock, the face cover 108 has a substantially circular keyhole having a diameter proportional to the diameter of the combination cylinder 4 of the key. In this embodiment, the face cover 108 will not receive the combination stud 4 with the coded projection 4a in the key previously described.

Fig. 8 further shows another key structure which is suitable for cooperation with this type of lock. In this embodiment, the cylindrical body 104 is provided with cutouts where encoding is required. An actuator 100 is provided within each cutout. Each actuator 100 is biased to extend within the center of the cylindrical body 104 and is shaped to provide the necessary encoding.

FIG. 9 shows the key with the actuator 100 entering the lock, the combination rod 12 entering the cylindrical body 104 . The combination rod 12 engages the actuator 100 and pushes it out through a cutout in the cylindrical body 104 . When the actuator 100 is moved, the corresponding code is exposed and engages the locking lever in the normal manner.

It will be appreciated that providing a lock with such a face cover 108 will further increase the security advantages of the lock. The face shield 108 will prevent anyone from peering into the lock and observing the external mechanism. Furthermore, the face shield 108 will make it extremely difficult for a person to access and tamper with the lock mechanism.

It is contemplated that key removal could be based on this alternative key configuration for use with the lock described in FIG. 1 .

It is also contemplated that the key and/or removal key may be a hybrid of these alternative key configurations. In other words, the key may be provided or removed with a combination of protrusions and actuators. For example, a key may have one actuator, as described above, and the remaining coded positions are simple protrusions. It will be appreciated that where such a hybrid key or removal key is used, the face cover will need to be shaped to at least receive such a key or removal key. This hybrid approach opens up possibilities for key silhouettes. For example, a lock may have a combination lever with a particular set of combination values and a face cover with a keyhole shaped to receive a key with a particular number of projections in a particular location. Hybrid keys can be properly coded to unlock such locks, however, only properly coded keys with protrusions in the correct position can enter the keyhole.

Although only preferred embodiments of the invention have been described, it is to be noted that the invention may be practiced with altered and additional features, as will be apparent to those skilled in the art.
