Definitions
- the invention relates to a locking arrangement for a locking mechanism for a door and of the kind that comprises a crossbar rotatably mounted in the door and connected in a conventional manner to a lock bolt or cremone bar in the door, and a handle for rotating the crossbar.
- door is, within the scope of the invention, meant an object for closing an opening in a wall. Examples are a door in a house, a safe, or a car.
- the object is a hinged door for closing and giving access through a door opening in a house.
- locking pawl is, in this context, meant a relatively short bar which, upon activation, can be displaced between a retracted position in the door and an extended position in which an end part of the locking pawl is extending out of a lateral edge of the door.
- said end part can extend into a corresponding locking opening in the wall or in a frame on the wall and thereby keep the door closed and if so desired, locked.
- cremone bar is meant a relatively long bar basically functioning in the same way as the above mentioned locking pawl.
- doors are provided with handles on both sides.
- the handles are pivotally mounted in the respective door and moment-resistantly connected to a usually square crossbar.
- a locking pawl on the crossbar engages with a lock bolt or cremone bar in such a way that the lock bolt or cremone bar is pushed back and forth or up and down between a closing position and an opening position upon turning of the handle.
- Said arrangement is normally used for merely keeping a door closed. If the door is to be locked as well, a separate lock is generally used, for example a cylinder lock having a cylinder that only can be turned by means of a specific key adapted to the lock. However, it is relatively costly to buy both arrangements and mount them on the same door.
- This solution is particularly convenient to use and especially in places where a lot of people must have access to the same area, for example a building.
- Another advantage is that a forgotten or missing key would not prevent a person from entering or exiting a door to e.g. his home or workplace. For example, a fingerprint cannot be forgotten or be lost.
- fingerprint scanners and code readers only function as long as they are connected to a power supply. If the power supply is interrupted or circuit of the locking arrangement is broken, the locking arrangement stops functioning. Then, a locked door cannot be opened so that people cannot get in or out of the door opening.
- a first aspect according to the invention providing a locking arrangement of the kind mentioned in the opening paragraph, that has a simple structure
- a second aspect according to the invention providing a locking arrangement of the kind mentioned in the opening paragraph, that can be mounted on a door at fewer costs than hitherto known
- a third aspect according to the invention providing a locking arrangement of the kind mentioned in the opening paragraph, that can be activated both electrically and manually
- a fourth aspect according to the invention providing a locking arrangement of the kind mentioned in the opening paragraph, that can be activated by a fingerprint and/or a code.
- the locking mechanism of the locking arrangement comprises a first coupling having two coupling parts for bringing the crossbar into and out of engagement with the handle, a second coupling having two coupling parts for bringing the crossbar into and out of engagement with the handle, an electrically operating first actuator for engaging and disengaging the first coupling, and a manually operated second actuator for engaging and disengaging the second coupling.
- This locking arrangement is inexpensive to produce and easy to mount on the door because there is no need for a separate lock to lock the door but only the handle or handles and the crossbar that are already there.
- the locking arrangement comprises electrically operated, biometric fingerprint scanners and/or code readers for activating the electrically operating first actuator for engaging and disengaging the first coupling.
- the crossbar and the handle can form part as essential structural elements of both couplings whereby the locking arrangement according to the invention is given a simple, inexpensive and very effective structure.
- one of the coupling parts of the first coupling according to the invention can be shaped as a disc mounted displaceably and moment-resistantly on the crossbar whereas its second coupling part can be made in an end section of the handle.
- the two coupling parts can e.g. be formed with cooperating claw couplings.
- the electrically operating first actuator for engagement and disengagement of the first coupling can furthermore comprise an engaging fork pivotally mounted on a pivot pin in the locking arrangement and pivotal about this pivot pin by an electric motor.
- the fork attacks the back (seen in the disengagement direction) of the first coupling disc.
- the two coupling parts of the first coupling are coupled when the current is switched on to the first actuator.
- the door can now be opened by turning the handle.
- the first actuator is only arranged to engage the disc of the first coupling with its second coupling part.
- the locking arrangement therefore comprises a spring having a spring power applying force to the disc of the first coupling in the disengagement direction whereby the first coupling is automatically disengaged if the power to the motor of the first actuator is disconnected, for example upon power failure.
- one of the coupling parts of the second coupling can furthermore be formed on a pin mounted displaceably and moment-resistantly in a recess in the handle whereas its second coupling part can be formed in an end section of the crossbar.
- both the crossbar and the handle are thus used for both the first coupling and the second coupling whereby the number of component parts for producing the two couplings is advantageously reduced.
- the manually operated, second actuator can comprise a cylinder lock moment-resistantly mounted in the recess of the handle and a screwed connection between the cylinder of the cylinder lock and the pin of the second coupling.
- the second coupling can be engaged by manually turning a key fitting the cylinder of the cylinder lock so that the pin of the second coupling is screwed into engagement with the second coupling parts of the second coupling on the crossbar by means of the screwed connection.
- the lock can be unlocked and the door be opened.
- the screwed connection can be arranged in such a way that the key has to be turned many times to engage the second coupling. An unauthorized person who is in possession of a correct key would therefore tend to abandon the attempt as the key normally only has to be turned a part of a rotation to be able to unlock a regular lock.
- the locking arrangement 1 is for a door 2 for closing a door opening 3 encircled by a frame 4.
- a door can be operated from both sides.
- a control panel 5 and a handle 6 are mounted on at least one side of the door.

Abstract
Description
- The invention relates to a locking arrangement for a locking mechanism for a door and of the kind that comprises a crossbar rotatably mounted in the door and connected in a conventional manner to a lock bolt or cremone bar in the door, and a handle for rotating the crossbar.
- By the concept door is, within the scope of the invention, meant an object for closing an opening in a wall. Examples are a door in a house, a safe, or a car.
- In the following, the invention is described on basis of the example that the object is a hinged door for closing and giving access through a door opening in a house.
- By the concept locking pawl is, in this context, meant a relatively short bar which, upon activation, can be displaced between a retracted position in the door and an extended position in which an end part of the locking pawl is extending out of a lateral edge of the door. When the door is closed, said end part can extend into a corresponding locking opening in the wall or in a frame on the wall and thereby keep the door closed and if so desired, locked.
- By the concept cremone bar is meant a relatively long bar basically functioning in the same way as the above mentioned locking pawl. Usually, there are two such bars working in opposition upon activation and engaging opposite locking openings in the wall or frame on the wall. A three-point locking is thereby formed together with a locking pawl.
- Normally, doors are provided with handles on both sides. The handles are pivotally mounted in the respective door and moment-resistantly connected to a usually square crossbar. A locking pawl on the crossbar engages with a lock bolt or cremone bar in such a way that the lock bolt or cremone bar is pushed back and forth or up and down between a closing position and an opening position upon turning of the handle.
- Said arrangement is normally used for merely keeping a door closed. If the door is to be locked as well, a separate lock is generally used, for example a cylinder lock having a cylinder that only can be turned by means of a specific key adapted to the lock. However, it is relatively costly to buy both arrangements and mount them on the same door.
- In recent years, locking arrangements have been developed that can be activated without use of keys. Instead, e.g. biometric fingerprint scanners or code readers are used to ensure that unauthorized persons do not unlock a door.
- This solution is particularly convenient to use and especially in places where a lot of people must have access to the same area, for example a building.
- Authorized persons are spared from having to have often large bunch of keys just as e.g. institutions or companies housed in a building are relieved from the trouble of having to keep track of keys that have been handed out and keep count of whether or not persons that are no longer authorized have forgotten to turn in the keys.
- Another advantage is that a forgotten or missing key would not prevent a person from entering or exiting a door to e.g. his home or workplace. For example, a fingerprint cannot be forgotten or be lost.
- However, fingerprint scanners and code readers only function as long as they are connected to a power supply. If the power supply is interrupted or circuit of the locking arrangement is broken, the locking arrangement stops functioning. Then, a locked door cannot be opened so that people cannot get in or out of the door opening.
- The above disadvantages of the known locking arrangements are overcome according to the invention by
in a first aspect according to the invention providing a locking arrangement of the kind mentioned in the opening paragraph, that has a simple structure,
in a second aspect according to the invention providing a locking arrangement of the kind mentioned in the opening paragraph, that can be mounted on a door at fewer costs than hitherto known,
in a third aspect according to the invention providing a locking arrangement of the kind mentioned in the opening paragraph, that can be activated both electrically and manually,
in a fourth aspect according to the invention providing a locking arrangement of the kind mentioned in the opening paragraph, that can be activated by a fingerprint and/or a code. - The novel and unique feature according to the invention, whereby this is achieved, is the fact that the locking mechanism of the locking arrangement comprises a first coupling having two coupling parts for bringing the crossbar into and out of engagement with the handle, a second coupling having two coupling parts for bringing the crossbar into and out of engagement with the handle, an electrically operating first actuator for engaging and disengaging the first coupling, and a manually operated second actuator for engaging and disengaging the second coupling.
- This locking arrangement is inexpensive to produce and easy to mount on the door because there is no need for a separate lock to lock the door but only the handle or handles and the crossbar that are already there.
- The locking arrangement according to the invention comprises electrically operated, biometric fingerprint scanners and/or code readers for activating the electrically operating first actuator for engaging and disengaging the first coupling.
- The presence of the manually operated second actuator for engagement of the second coupling effectively ensures that a locked door can be unlocked if the power to the locking arrangement should fail.
- According to the invention, the crossbar and the handle can form part as essential structural elements of both couplings whereby the locking arrangement according to the invention is given a simple, inexpensive and very effective structure.
- In an especially advantageous and simple embodiment, one of the coupling parts of the first coupling according to the invention can be shaped as a disc mounted displaceably and moment-resistantly on the crossbar whereas its second coupling part can be made in an end section of the handle. The two coupling parts can e.g. be formed with cooperating claw couplings.
- According to the invention, the electrically operating first actuator for engagement and disengagement of the first coupling can furthermore comprise an engaging fork pivotally mounted on a pivot pin in the locking arrangement and pivotal about this pivot pin by an electric motor. The fork attacks the back (seen in the disengagement direction) of the first coupling disc.
- The two coupling parts of the first coupling are coupled when the current is switched on to the first actuator. The door can now be opened by turning the handle.
- The first actuator is only arranged to engage the disc of the first coupling with its second coupling part.
- According to the invention, the locking arrangement therefore comprises a spring having a spring power applying force to the disc of the first coupling in the disengagement direction whereby the first coupling is automatically disengaged if the power to the motor of the first actuator is disconnected, for example upon power failure.
- According to the invention, one of the coupling parts of the second coupling can furthermore be formed on a pin mounted displaceably and moment-resistantly in a recess in the handle whereas its second coupling part can be formed in an end section of the crossbar.
- As it appears, both the crossbar and the handle are thus used for both the first coupling and the second coupling whereby the number of component parts for producing the two couplings is advantageously reduced.
- In an advantageous embodiment, the manually operated, second actuator can comprise a cylinder lock moment-resistantly mounted in the recess of the handle and a screwed connection between the cylinder of the cylinder lock and the pin of the second coupling.
- If the power to the first actuator fails, the second coupling can be engaged by manually turning a key fitting the cylinder of the cylinder lock so that the pin of the second coupling is screwed into engagement with the second coupling parts of the second coupling on the crossbar by means of the screwed connection.
- Now, the lock can be unlocked and the door be opened.
- According to the invention, the screwed connection can be arranged in such a way that the key has to be turned many times to engage the second coupling. An unauthorized person who is in possession of a correct key would therefore tend to abandon the attempt as the key normally only has to be turned a part of a rotation to be able to unlock a regular lock.
- The invention will be explained in greater details below, describing only exemplary embodiments and advantageous characteristics with reference to the drawing, in which
-
Fig. 1 is a front fractional view of a door having a control panel and a handle for a locking arrangement according to the invention, -
Fig. 2 is a perspective exploded view of a locking mechanism for the locking arrangement, -
Fig. 3 is a side elevational view of the locking mechanism in a locking state, -
Fig. 4 is a view of the locking mechanism infig. 3 in an electrically activated unlockable state, -
Fig. 5 is a view of the locking mechanism infig. 3 in a manually activated unlockable state, -
Fig. 6 is a diagrammatic side elevational view of an electrically operated actuator for bringing the locking mechanism into the unlockable state infig. 4 , and -
Fig. 7 is a front view of the same. - In the following, an exemplary embodiment according to the invention is described in which the locking arrangement 1 is for a
door 2 for closing a door opening 3 encircled by a frame 4. - Usually, a door can be operated from both sides. In
fig. 1 it is shown that a control panel 5 and ahandle 6 are mounted on at least one side of the door. - In the case shown, a lock bolt 7 is pushed into a locking opening 8 formed in a lock washer 9 recessed in the
lateral edge 10 of the frame. The door is closed and possibly locked. - The door can be unlocked electrically by means of a fingerprint on a
fingerprint scanner 11 or by entering a specific code on acode reader 12. Both thefingerprint scanner 11 and thecode reader 12 are located on acover 13 on thedoor 2. - Alternatively, the door can be unlocked manually by a key fitting a
cylinder lock 14 mounted in thehandle 6 which is pivotally mounted on thecover 13. - When the door is to be opened in one of the above-described ways, a
locking mechanism 15 in the locking arrangement 1 is activated. This locking mechanism, shown in an exploded view infig. 2 , is partly located in a recess (not shown) in the door. - The
locking mechanism 15 comprises thecylinder lock 14 shown infig. 1 in thehandle 6. In the cylinder lock is acylinder 16 in which agroove 17 is made in itsend face 18. Anadapter 19 having a threadedconnection 20 fits thegroove 17. Apin 21 is screwed onto the threaded connection of the adapter. The cylinder can be turned by a key 22 having a predetermined shape and fitting a keyhole 23 in thecylinder 16. The keyhole is shown infig. 1 . - The
locking mechanism 15 furthermore comprises acrossbar 24 having in this case a square cross section. The crossbar is rotatably mounted in the door and connected in a conventional manner to the lock bolt 7. - On rotating the crossbar, the locking pawl 8 is pushed sideways out of the
door 2 in a normal manner and into the locking opening 8 in the lock washer 9. - A
disc 25 is displaceably, but moment-resistantly mounted on the crossbar. The disc is formed withclaws 27 which can cooperate withcorresponding claws 28 on the end part of thehandle 6. - A
second disc 26 is fastened on the end of the crossbar. The disc is made with aslot 29 which can cooperate with a corresponding key 30 on thepin 21. -
Figs. 3, 4 , and5 show in detail how thelocking mechanism 15 is arranged and functions. - The
displaceable disc 25 withclaws 27 form together with theclaws 28 on the end part of the handle 6 a first coupling whereas the fixed disc with theslot 29 form a second coupling together with thepin 21 with the key 30. - In
fig. 3 , both couplings are disengaged. If thedoor 2 is closed, it is also locked as there is no connection between thecrossbar 24 and thehandle 6 which thereby can be turned without bringing the crossbar. -
Figs. 6 and 7 are diagrammatic views of an electrically operatedactuator 31 for engaging thefirst coupling fork 32 pivotally mounted on apivot pin 33 fastened in the door. The engaging fork is provided with twopins 34 catching behind thedisc 25. Anelectric motor 35 has apinion drive 36 engaging atoothed wheel 37 on thepivot pin 33. On connecting the motor to a power source (not shown), it rotates the engaging fork to the position shown infig. 6 . - In the situation shown in
fig. 4 , the claws of thedisplaceable disc 25 are connected to theclaws 28 of the handle, resulting in the crossbar and the handle being connected to each other. This means that the door now can be unlocked merely by turning the handle so that the crossbar is rotated and the lock bolt 7 thereby is pulled out of the locking opening 8 in the frame 4. - The motor can be connected to a power source (not shown) by providing a fingerprint on the
fingerprint scanner 11 of the control panel or alternatively entering a predetermined code on thecode reader 12 of the control panel. - If the power fails, the
displaceable disc 25 of the first coupling is pushed back by apressure spring 38 acting between thedisplaceable disc 25 and the fixeddisc 26 until it comes up against acollar 39 on thecrossbar 24. - The situation is now the same as the one shown in
fig. 3 . A locked door cannot be unlocked whereby the serious problem that people cannot get either in or out of the door might occur. - This problem is solved by means of the
second coupling disc 26 with theslot 29 and thepin 21 with the key 30. - As mentioned earlier, the
adapter 19 is fitted into agroove 17 in theend face 18 on thecylinder 16 of thecylinder lock 14, and thepin 21 is screwed onto a threadedconnection 20 on the adapter. - Therefore when the cylinder is turned with the key 22, the
pin 21 is screwed outwards on the threadedconnection 20 of theadapter 19 until its key 30 engages theslot 29 in the fixeddisc 26 on thecrossbar 24, the adapter being retained against turning by awedge 40 in akey groove 41 in arecess 42 in the handle. - In this way, a locked door can be opened manually if the power to the locking arrangement fails.
