    LOCK CASSETTE AND SAFETY DOOR TECHNICAL FIELD The present invention relates to the general field of safety locking systems, and specifically to a lock cassette and a safety door.
    BACKGROUND OF INVENTION Security storages are often placed outdoors and left unattended. Since a security storage mayremain closed over long periods of time, the locking mechanism may corrode, which mayultimately lead to malfunctioning of the locking mechanism. The locking mechanism isgenerally built into the door of the safety storage, with the consequence that the lockingmechanism cannot be repaired without dismantling the door of the safety storage, leaving thecontents of the storage exposed during repairs. Repairing the locking mechanism on siterequires transporting a large number of spare parts to the site, since the problem is generallyunknown. Once the repair of the door has started, the safety storage cannot be left withoutleaving its content unguarded. The repairs can thus generally not be started one day and finished on another.
    An ordinary door has a locking mechanism that is easy to replace, but such a solution is unfitfor a safety storage. Security storages and similar spaces for storing items such as weapons,explosives and valuable materials require doors which can withstand illicit entry. One way ofreinforcing a door is to include concrete and/ or various metals in the door material.However, this does not hinder illicit entries where the door is opened by tampering ordamaging the locking system of the door. In some cases, the locking system is tampered withusing keys and key-like objects, while in other cases the locking system is tampered with by drilling or other types of attack.
    There is a need for a locking system than can be easily repaired. There is also a need for alocking system that does not unlock when it is tampered with.
    SUMMARY OF THE INVENTION The present invention relates to a lock cassette, comprising: at least one lock bolt connecting piece, adapted for releasable engagement with a lock cassette engaging end portion of a door integrated lock bolt of a door when the lock cassette is mounted in a lock cassette receivingcavity of the door; a lock bolt maneuvering mechanism, configured to displace the at leastone lock bolt connecting piece between an extended position and a retracted position, tothereby displace the lock bolt between an extended position and a retracted position; and atleast one lock bolt locking arrangement, configured to lock the movability of the at least onelock bolt connecting piece when a locking action is effected, and unlock the movability of theat least one lock bolt connecting piece when an unlocking action is effected. When a lockingaction has been effected, and the movability of the lock bolt connecting piece is locked, thelock bolt connecting piece, and thereby the lock bolt, cannot be moved until an unlockingaction is effected. Such a lock cassette can be mounted into a door comprising doorintegrated lock bolts and interact with these lock bolts. If there is a problem with the lockingmechanism, the lock cassette can easily be removed and replaced with another similar lock CaSSette.
    In embodiments, each lock bolt connecting piece is arranged to engage with the lock cassetteengaging end portion of a corresponding door integrated lock bolt when the lock cassette isinserted into the cassette receiving cavity of the door in a direction perpendicular to the doorintegrated lock bolts. In embodiments, the lock bolt connecting piece is a plate with a cavity,and engages a groove in the lock cassette engaging end portion of the corresponding doorintegrated lock bolt in a fork like engagement. The other way around is also possible, so thatthe lock bolt connecting piece contains a groove, and the lock cassette engaging end portioncomprises a cavity which engages the groove. Any type of releasable engagement between thelock bolt connecting piece and the lock cassette engaging end portion of a corresponding doorintegrated lock bolt is conceivable. This enables a simple yet effective engagement of the lockcassette with the lock bolts.
    In embodiments, the lock cassette further comprises at least one cassette integrated lock bolt,configured to also be displaced by the lock bolt maneuvering mechanism between anextended position and a retracted position, wherein the movability of the cassette integratedlock bolt is also locked and unlocked by the lock bolt locking arrangement. This enables easyintegration of an extra lock bolt into a safety door, in the position where the lock cassette is mounted.
    In embodiments, the at least one lock bolt locking arrangement comprises a key receivingcavity configured to interact with a corresponding key, the locking action being the turning ofthe key in one direction in the key receiving cavity, and the unlocking action being the turning of the key in the opposite direction in the key receiving cavity. The at least one lock bolt locking arrangement may e.g. comprise a lock bolt safety locking mechanism which isarranged to immobilize and permanently lock the movability of the at least one lock boltconnecting piece and any cassette integrated lock bolt when the key receiving cavity istampered with. This means that the lock bolts are impossible to retract, and thus the door cannot be opened by simply destroying the locking system.
    The lock bolt safety locking mechanism may e.g. comprise a biasing arrangement, a biasingreleaser, and a connector, for example in the form of a wire, connecting the biasingarrangement to the biasing releaser. The biasing releaser may e.g. comprise a fragile materialarranged to break when the key receiving cavity is tampered with, thereby releasing thebiasing arrangement so that the lock bolt connecting pieces (and thereby the lock bolts) andany cassette integrated lock bolt become immobilized and permanently locked. The biasingarrangement may e.g. be spring biased, and may e.g. comprise two parallel springs. This is asimple yet effective embodiment of a tamper-proof locking system, but other embodimentsare of course also possible, as long as the lock bolt safety locking system permanently locks the movement of the lock bolts when the key receiving cavity is tampered with.
    In embodiments, the lock cassette comprises at least two lock bolt locking arrangements,each of which comprising a lock bolt safety locking mechanism. Each lock bolt lockingarrangement may be connected to any number of lock bolt connecting pieces, and thereby toany number of lock bolts. Each lock bolt locking arrangement may comprise a key receivingcavity configured to interact with a corresponding key, which means that at least two keys arenecessary for opening the door if there are at least two lock bolt locking arrangements. This makes the locking system safer.
    In embodiments, the lock bolt maneuvering mechanism comprises a coupling which isrotatable around a rotation axis and operably connected to the lock bolt connecting piece,and also to any cassette integrated lock bolt, to translate a rotational movement of thecoupling to a rectilinear movement of the lock bolts. The coupling may be operated from theoutside of the cassette by a turning device. This makes it easy to open the door when the lock bolts are unlocked.
    In embodiments, the lock bolt maneuvering mechanism is electronically operated based on areceived signal. The signal may be triggered at least partly by the locking and unlockingactions, such as the turning of the key in the key receiving cavity. This enables automaticopening of the door as soon as it has been unlocked, without manual actuation of the lock bolt maneuvering mechanism.
    The present invention further relates to a safety door comprising a lock cassette receivingcavity adapted for receiving an exchangeable lock cassette, and at least one door integratedlock bolt having a wall engaging end portion and a lock cassette engaging end portion. Such a safety door is easy to repair by exchanging the exchangeable lock cassette.
    The present invention further relates to a safety door comprising a lock cassette receivingcavity, the above described lock cassette inserted into the lock cassette receiving cavity, andat least one door integrated lock bolt having a wall engaging end portion and a lock cassetteengaging end portion, wherein each lock bolt connecting piece of the lock cassette is engagedwith a corresponding lock cassette engaging end portion of the door integrated lock bolt.Such a safety door is easy to repair by removing the lock cassette and replacing it with another similar lock cassette.
    In embodiments, the safety door comprises at least two door integrated lock bolts. This makes the safety door safer.
    The scope of the invention is defined by the claims, which are incorporated into this sectionby reference. A more complete understanding of embodiments of the invention will beafforded to those skilled in the art, as well as a realization of additional advantages thereof,by a consideration of the following detailed description of one or more embodiments.
    Reference will be made to the appended sheets of drawings that will first be described briefly.
    DRAWINGS The invention is explained in detail below with reference to the accompanying drawings, inwhich: Figure 1 shows a schematic view of a door comprising a lock cassette receiving cavity and two door integrated lock bolts according to embodiments of the invention; Figure 2 shows a partly exploded view of a lock cassette according to embodiments of the invention;Figure 3a shows a side view of the lock cassette of figure 2; Figure 3b shows a view of a cross-section B-B in figure 3a.
    Embodiments of the present disclosure and their advantages are best understood by referringto the detailed description that follows. It should be appreciated that like reference numerals are used to identify like elements illustrated in one or more of the figures.
    DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings, there is illustrated one specific exemplifying embodiment of alocking system in accordance with the inventive concept. Other embodiments are of course conceivable within the scope of the invention.
    Figure 1 shows a schematic view of a door 10 comprising a lock cassette receiving cavity 12and two door integrated lock bolts 14, 16 according to embodiments of the invention. Thedoor integrated lock bolts 14, 16 have wall engaging end portions 14a, 16a configured toengage with the wall around the door when the door is locked. The wall engaging endportions 14a, 16a are adapted to engage with cavities arranged in any part of the wall or doorframe surrounding the actual openable door 10. In embodiments, the door 10 is mounted ine.g. a concrete wall comprising cavities for receiving the wall engaging end portions 14a, 16aof the door integrated lock bolts 14, 16. In embodiments, the door 10 is mounted in a doorframe comprising cavities for receiving the wall engaging end portions 14a, 16a of the doorintegrated lock bolts 14, 16, which door frame is mounted in a wall. In the lock cassette receiving cavity 12, a lock cassette 20 can be mounted.
    Figure 2 shows a partly exploded view of a lock cassette 20 according to embodiments of theinvention. The shown lock cassette 20 comprises a cassette integrated lock bolt 23. Lock boltconnecting pieces 21 in the form of plates with cavities engage with grooves in the lockcassette engaging end portions 14b, 16b of the schematically shown door integrated lock bolts14, 16 in a fork like engagement when the lock cassette 20 is inserted into the cassettereceiving cavity 12 of the door 10 in a direction perpendicular to the door integrated lock bolt14, 16. For a vertical door 10 with the lock cassette receiving cavity 12 positioned on the side,insertion in a direction perpendicular to the door integrated lock bolt 14, 16 is a lateralinsertion, but for other types of doors, such as hatches, insertion in a direction perpendicular to the door integrated lock bolt 14, 16 may be e.g. a vertical insertion.
    Other types of releasable engagement of the lock bolt connecting pieces 21 with the lockcassette engaging end portions 14b, 16b of the door integrated lock bolts 14, 16 are of courseconceivable. For example, the lock bolt connecting pieces 21 may contain grooves, and the lock cassette engaging end portions 14b, 16b may comprise cavities which engage the grooves. In another example, the lock bolt connecting pieces 21 comprise rods which are inserted into holes in the corresponding lock cassette engaging end portions 14b, 16b.
    The lock cassette comprises a lock bolt maneuvering mechanism, configured to displace thelock bolt connecting pieces 21 (and thereby the door integrated lock bolts 14, 16) and thecassette integrated lock bolt 23 between an extended position and a retracted position. Thelock cassette further comprises two lock bolt locking arrangements, configured to lock themovability of the lock bolt connecting pieces 21 (and thereby the door integrated lock bolts14, 16) and the cassette integrated lock bolt 23 when a locking action is effected, and unlockthe movability of the lock bolt connecting pieces 21 (and thereby the door integrated lockbolts 14, 16) and the cassette integrated lock bolt 23 when an unlocking action is effected. Thelocking of the movability means that the lock bolts 14, 16, 23 cannot be moved until an unlocking action has been effected.
    Each of the lock bolt locking arrangements comprises a key receiving cavity 26 configured tointeract with a corresponding key. The locking action is thus the turning of the key in onedirection in the key receiving cavity 26, and the unlocking action is the turning of the key inthe opposite direction in the key receiving cavity 26. The shown lock cassette 20 comprisestwo keyholes 28, arranged on the outside of the cassette, which are aligned with the key receiving cavities 26.
    Each of the lock bolt locking arrangements comprises a lock bolt safety locking mechanismwhich is arranged to immobilize and permanently lock the lock bolt connecting pieces 21(and thereby the door integrated lock bolts 14, 16) and the cassette integrated lock bolt 23when the key receiving cavity 26 is tampered with. Each of the shown lock bolt safety lockingmechanisms comprises a biasing arrangement 24, a biasing releaser 25, and a connector 27,for example in the form of a wire, which connects the biasing arrangement 24 to the biasingreleaser 25. The biasing releaser 25 may comprise or be configured of a fragile material suchas glass, preferably a sheet of glass. It may be arranged to break when the key receiving cavityis tampered with, thereby releasing the biasing arrangement 24 so that the lock boltconnecting pieces 21 (and thereby the door integrated lock bolts 14, 16) and the cassetteintegrated lock bolt 23 become immobilized and permanently locked. The permanent lockingmeans that the lock bolts 14, 16, 23 cannot be moved even if an unlocking action is effected.The shown biasing arrangement 24 comprises two parallel springs, but many different types of biasing arrangements are of course conceivable.
    In the shown embodiment, the two keyholes 28 are aligned with two lock bolt locking arrangements and two biasing releasers 25, and arranged on the outside of the door.
    Additionally, the connector 27 is in contact with one or more rods having the function ofpulleys which help to configure the components with space efficiency within the casing,provide a free passage for the connector when the lock releaser breaks due to tampering anddistribute biasing spring force in the connector to enable a stronger spring force being retained by the biasing releaser 25.
    The shown lock bolt maneuvering mechanism comprises a coupling 29 which is rotatablearound a rotation axis and operably connected to the lock bolts 14, 16, 23 to translate arotational movement of the coupling 29 to a rectilinear movement of said lock bolts 14, 16,23. As shown in figure 3a, the coupling 29 is operated from the outside of the cassette by aturning device 31 which can be rotated by an operator. Moreover, as shown in figure 3b, thecoupling 29 is operably connected to the cassette integrated lock bolt 23 with a first lock boltarm 32, which is arranged perpendicularly in relation to the rotation axis. Additionally, thefirst lock bolt arm 32 is at its respective ends supported at pivotal joints disposed on the coupling 29 and on the cassette integrated lock bolt 23.
    In embodiments, the lock bolt maneuvering mechanism is electronically operated based on areceived signal. The signal may e.g. be triggered at least partly by the locking and unlocking actions, so that the door may open automatically as soon as it has been unlocked.
    In the shown embodiment, each lock bolt connecting piece 21 is connected to the coupling 29via a locking latch 22 and a locking latch arm 33. The locking latch arm 33 is operablyconnected to the locking latch 22 to translate a rotational movement of the coupling 29 to arectilinear movement of the locking latch 22, and thereby a rectilinear movement also of thelock bolt connecting piece 21. The locking latch 22 is arranged perpendicularly in relation tothe rotation axis of the coupling 29, and the lock bolt locking arrangement is configured to beable to lock the movability of the locking latch 22, thereby locking the movability of thecoupling 29 and also of the cassette integrated lock bolt 23. The shown embodimentcomprises two lock bolt locking arrangements, as well as two locking latches 22 and two locking latch arms 33 engaging the respective locking latch 22.
    In the shown embodiment, the biasing arrangement 24 comprises a symmetric pair of springbiased safety locking rods, configured to be able to lock the movability of the locking latch 22and thus the lock bolt connecting piece 21. Consequently, when the lock bolt lockingarrangement is tampered with, the biasing releaser 25 breaks. The springs are then releasedand force the safety locking rods into a recess in the locking latch 22, thereby locking themovability of the locking latch 22 and thus the lock bolt connecting piece 21. Consequently, the coupling 29, and thereby the bolts 14, 16, 23, are immobilized and permanently locked, i.e. it is thereafter not possible to unlock the locking system with operator keys. Instead, the door has to be demounted and/ or destroyed in order to enter the space protected by the door.
    The shown embodiment comprises two locking latches 22, each provided with an associatedsafety locking mechanism configured as described above. Each locking latch is connectedwith a corresponding connecting piece 21, connecting the locking latch 22 to the doorintegrated lock bolts 14, 16 so that the door integrated lock bolts 14, 16 move simultaneouslywith the cassette integrated lock bolt 23. The connecting piece 21 is the interface between the lock cassette 2o and the door integrated lock bolts 14, 16.
    The shown lock cassette 2o comprises a casing having two preferably symmetric side plates30 provided with recesses providing guides for moving parts within the casing, shoulders for fixed parts within the casing and screws for assembling the casing.
    The locking system according to the present invention can be made in a variety of sizes. Oneof ordinary skill in the art will understand that a variety of sizes are possible without compromising the utility of the locking system.
    The lock cassette may comprise any number of lock bolts, lock bolt connecting pieces andlock bolt locking arrangements, e.g. one, two, three or four. There may be just one lock boltlocking arrangement even if there are several lock bolts, and there may be several lock bolt locking arrangements even if there is only one lock bolt and/ or lock bolt connecting piece.
    The locking system according to the present invention may be utilized in any type of door,such as regular vertical doors or doors in the form of hatches mounted in any direction.Particularly, the locking system is used in doors which aim to hinder illicit entries such asillicit entries to rooms and spaces where explosives, weapons and valuables are being stored.One of ordinary skill in the art will understand that there are a variety of doors, as well asother types of arrangements for keepings materials locked, where the locking system according to the present invention can be deployed.
    While the locking system according to the present invention has been described withreference to the above specific examples, this is intended to be illustrative only and not to belimiting of the disclosure, it is noted that changes, additions and/ or deletions may be made tothe disclosed examples without departing from the spirit and scope of the disclosure. Thescope of the disclosure is therefore not covered by any specific example, but rather by the following claims.
    The foregoing disclosure is not intended to limit the present invention to the precise forms orparticular fields of use disclosed. It is contemplated that various alternate embodiments and/ or modifications to the present invention, whether explicitly described or impliedherein, are possible in light of the disclosure. Accordingly, the scope of the invention is defined only by the claims.
