Description

SAFETY LOCKING SYSTEM TECHNICAL FIELDThe present invention relates to the general field of locking systems and more particularly toa locking system which is not possible to unlock if the locks of the locking system are tam- pered with.

BACKGROUND OF INVENTION Security storages and similar spaces for storing items such as weapons, explosives and valua-ble materials require doors which can withstand illicit entry. One way of re-enforcing a dooris to include concrete and/ or various metals in the door material. However, this does nothinder illicit entries where the door is opened by tampering or damaging the locking systemsof the door. In some cases the locking system is tampered with keys and key-like objects,while in other cases the locking system is tampered with by drilling or other ways of attacking the locking system.

Consequently, there is a need for a locking system which does not unlock when said locking system is tampered with.

OBJ ECT OF THE INVENTIONThe object of the present invention is to provide a locking system which is not possible to unlock if one or several locks of a locking system are tampered with.

SUMMARY OF THE INVENTION The preferred embodiment of the present invention relates to a locking system comprising acasing, an operator lock mounted within said casing, a main lock bolt of the locking systemwhich is displaceable between a fully displaced locking position and a fully retracted un-locked position, a main lock bolt maneuvering mechanism operable from outside of said cas-ing and configured to displace said main lock bolt between fully displaced locking positionand a fully retracted unlocked position, said lock bolt maneuvering mechanism being config-ured to be lockable by said operator lock, and at least one safety locking device, wherein saidsafety locking device is arranged at the operator lock and conﬁgured to release a safety boltsystem arranged to lock said lock bolt maneuvering mechanism when said lock is tamperedwith.

DETAILED DESCRIPTION OF THE INVENTION Referring to ﬁgures 1-3 of the drawings, there are illustrated two specific exemplifying em-bodiments of a locking system in accordance with the inventive concept, i.e. a locking systemwhich is not possible to unlock if the locks of the locking system are tampered with. The lock-ing system exempliﬁed in Figure 1 and Figure 2 show different configurations of the locking system.

An embodiment of the present invention relates to a locking system comprising a. a casing (40) ; b. an operator lock (33) mounted within said casing; c. a main lock bolt (23) of the locking system which is displaceable between a ful-ly displaced locking position and a fully retracted unlocked position; d. a main lock bolt maneuvering mechanism operable from outside of said casingand configured to displace said main lock bolt (23) between fully displacedlocking position and a fully retracted unlocked position, said lock bolt maneu-vering mechanism being configured to be lockable by said operator lock (33); e. at least one safety locking device; wherein said safety locking device is arranged at the operator lock (33) and configured torelease a safety bolt system arranged to lock said lock bolt maneuvering mechanism when said lock (33) is tampered with.

In the embodiments illustrated in Figures 1-3, the main lock bolt maneuvering mechanismcomprises a coupling (3) which is rotatable around a rotation axis and operably connected tothe main lock bolt (23) to translate a rotational movement of the coupling (3) to a rectilinear movement of the main lock bolt (23). Moreover, the coupling (3) is operably connected to the main lock bolt (23) with a main lock bolt arm (17a) and the main lock bolt arm (17a) isarranged perpendicularly in relation to the rotation axis. Additionally, the main lock bolt arm(17a) at its respective ends is supported at pivotal joints disposed on the coupling (3) and onthe main lock bolt (23). The coupling (3) is operated from the outside of the casing by a turn-ing device (45) which can be rotated by an operator. Additionally, the locking system is con-figured to comprise one or more keyholes (39) which are aligned with one or more operator locks and wherein said keyholes are preferably arranged on the outside of the casing.

Reference is now made to the embodiments illustrated in Figures 1-3 in which a locking latch(2o,46) is connected to the coupling (3) via a locking latch arm (17b). The locking latch arm(17b) is operably connected to the locking latch (2o,46) to translate a rotational movement ofthe coupling (3) to a rectilinear movement of the locking latch (2o,46). The locking latch(2o,46) is arranged perpendicularly in relation to the rotation axis of the coupling (3) and theoperator lock (33) is configured to be able to lock the movability of the locking latch (2o,46)by means of an operator lock bolt (48) and thereby locking the movability of the coupling (3)and of the main lock bolt (23). The preferred embodiments of the invention shown in Figures1-3 comprise two operator locks (33), as well as two pairs locking latches (2o,46) and twolocking latch arms (17b) engaging the respective pair of locking latches (2o,46), which are allconfigured as described above. Further, embodiments are configured with one or more, e.g. 4 operator locks with associated safety locking devices.

The safety locking device comprises a spring biased safety bolt system (9), a safety lock re-leaser (31), and a connector (41), for example in the form of a wire, which connects the safetybolt system (9) to the safety lock releaser (31). The safety lock releaser (31) is configured of afragile material such as glass, preferably a sheet of glass. The safety lock releaser (31) breakswhen the operator lock (33) is tampered with and the safety bolt system (9) is consequentlyreleased. The safety bolt system (9), in this embodiment conﬁgured in a symmetric pair ofspring biased safety locking bolts (7), configured to be able to lock the movability of the lock-ing latch (2o,46) and comprises at least one spring, preferably two parallel springs. Conse-quently, when the operator lock (33) is tampered with, the safety lock releaser (31) breaks,the springs are then released and force the safety locking bolts into a recess in the respectivelocking latch (2o,46) thereby locking the movability of said locking latch (2o,46). Conse-quently, the coupling (3) and thereby the main lock bolt (23) is immobilized and permanentlylocked, i.e. it is thereafter not possible to unlock the locking system with operator keys. In-stead, the door comprising the locking system has to be demounted and/ or destroyed in or- der to enter the space protected by the door. The embodiments of the invention shown in Figures 1-3 comprises two locking latch (20,46) pairs each being provide with an associated safety locking device conﬁgured as described above.

The preferred embodiments in Figures 1-3 comprise locking systems configured to comprisetwo keyholes (39), which are aligned with two operator locks (33) and two lock releasers(31), and wherein the keyholes are arranged on the outside of the casing. Additionally, theconnector (41) in the preferred embodiments is preferably configured to be in contact withone or more rods (4) having the function of pulleys which help to conﬁgure the componentswith space efﬁciency within the casing, provide a free passage for the connector when thelock releaser breaks due to tampering and distribute biasing spring force in the connector to enable a stronger spring force being retained by the safety lock releaser (31).

The spring biased safety bolt system (9) illustrated in the shown embodiments exempliﬁed inFigures 1-3 comprises two parallel springs (44) which are attached to two parallel rodswherein the rods are connected to two safety locking bolt (7). The spring biased safety boltsystem further comprises two additional rods, the first rod which is connected to one end of the connector (41) and the second rod (12) which may be in contact with the connector.

The casing comprises two preferably symmetric side plates (40) provided with recessesproviding guides for moving parts within the casing, shoulders for fixed parts within the cas- ing and screws for assembling the casing.

Although figures 1-3 relate to locking systems with two operator locks (33), it is intended tobe illustrative only. A locking system according to the present invention may also comprisefrom one to four operator locks (33) and wherein a safety locking device is arranged at each of the operator locks (33).

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 com- promising the utility of the locking system.

The locking system according to the present invention is utilized in any type of door. Particu-larly, the locking system is used in doors which aim to hinder illicit entries such as illicit en-tries 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 as other 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 with refer-ence to the above specific example in Figures 1-3, this is intended to be illustrative only andnot to be limiting of the disclosure, it is noted that changes, additions and/or deletions maybe made to the disclosed examples without departing from the spirit and scope of the disclo-sure.
