- cam 32 extends within the path of rotation of the lip 72 and furthermore within the path of rotation of the lip 21 as well as of the lip 11.
- a lock assembly 2 according to the invention is accommodated in the front door 5, the lock assembly having a lock case or housing formed by walls 3a, 3b, 3c and 4, in which various parts shown in the figures 5 and further have been accommodated.
- the lock assembly comprises a latch 170, arranged on a pin 171, having a stop 172.
- the latch 170 is spring-biassed into a projecting position, extending beyond the lock plate 6.
- the lock assembly 2 is furthermore provided with a dead bolt 160, that is rotatable about fixed pin 161 and is provided with a slot 162 and a hook 163.
- a pin 151 (see figure 5 ) is accommodated, which pin 151 is permanent to bolt plate 150 that can be slid up and down.
- the bolt plate 150 is slightly shorter than the distance between the walls 3a and 3b of the lock case, and reciprocally slidable between them.
- the bolt plate 150 is provided with turned ends 156, 159, and formed as one unity with vertical strips 155, which form a connection that is not further shown with other dead bolts, which are accommodated in a manner that is not shown in the door 5.
- an operation plate 300 is arranged, which is also strip-shaped and hinged to the ear 14 of the second lever handle plate 10 by means of a pin passed through the hole 15.
- the upper end of the operation plate 300 is provided with a vertical slot 303, in which a pin 335 which will be further discussed is accommodated in a manner so as to be slidable up and down.
- the operation plate 300 as seen in the drawing on the left-hand side, is provided with a downward turned lip 302.
- the upper edge of the operation plate 300 forms a stop edge 301.
- An inclined edge 304 is furthermore provided near the upper edge.
- a torsion spring 180 is furthermore shown, which is permanent to the lock case, and abuts the turned lip 25 with the arm 181, as can be seen in figures 5 and 6 .
- a sliding plate 220 is provided below the operation plate 300, which sliding plate at the lower end 240 is provided with an pilot edge 241.
- the pilot edge 241 is in contact with the turned lip 92 of the coupling catch 90.
- a transversely projecting pin 221 is attached, which extends in a slot 337 of a sliding plate 330.
- the sliding plate 220 is vertically movable. The sliding plate 220 is then guided by the permanent pin 190 extending in the vertical elongated hole 223 of the sliding plate 220 and by the permanent pin 191 extending in the slot 224.
- the pin 221 and thus the plate 220 is pre-biassed downward by a torsion spring 341, which is provided with two arms 342a, 342b.
- the arm 341 a supports against the wall 3a of the lock case and the other arm 342b supports against the pin 221.
- the sliding plate 330 is slidable in the direction G (among others figure 8A ) and at the lower edge is provided with a run-in edge 331, a recess 332 and a run-out edge 333.
- the slot 337 has a recess 334 and at the right end it has a recess 338. In those recesses, and also in the slot 337, the pin 221 extends, which as already stated, is permanent to the sliding plate 220.
- the sliding plate 330 is furthermore provided with a slot 336 opening towards the clear of the frame and into which a pin 190 extends which is permanent to the lock case.
- the sliding plate 330 is furthermore provided with a horizontal slot 339, into which a pin 327 extends, which is permanent to the lock case, and around which the torsion spring 341 is arranged.
- a pin 335 is permanently attached on the sliding plate 330, which pin 335 extends into the slot 303 of plate 300.
- a tilting plate 320 is situated above the sliding plate 330, which tilting plate can be hinged about a pin 500 that is permanent to the sliding plate 330 and which is provided with hole 328 into which the pin 335 of the sliding plate 330 extends with play.
- the tilting plate 320 thus is tiltable with respect to the sliding plate 330.
- the tilting plate 320 at its right upper end is provided with lip 320a, to which an end of a compression spring 344 is attached. With its other end the compression spring 344 is attached to lip 343 of sliding plate 330.
- a cam 320d is provided, which may lie in the path of edge 304 of plate 300.
- an abutment edge 325 is provided at the opposite side of the tilting plate 320, top left.
- the tilting plate 320 is provided with a shoulder 321 a, and above it with a concave edge 321 b.
- the tilting plate 320 is provided with a slot 324 in which a first receiving space 322 and a second receiving space 323 are provided, separated by a ridge 329.
- the edge of the ridge 329 facing the receiving space 323, is oriented such that it may exert a clamping action on the pin 335, in the situation shown in figure 7A .
- the cam 151 is thus also urged downward.
- the cam 151 is thereby moved within hole 162 of hooked bolt 160, as a result of which this hooked bolt 160 is rotated about fixed hinge point 161 into the extended locking position shown in figure 9 .
- the bolt plate 150 is connected to hooked bolts that are not further shown and arranged in the lower portion of the door by an espagnolette plate 155 that is common per se. These hooked bolts are extended in a manner that can be compared with hooked bolts 160.
- the latch is not operated here.
- the ear 14 that is integrally formed therewith in a shifted manner, co-rotates, and which by means of hole 15 and pin 301 is hinged to the elongated operation plate 300 (see figures 5 and 6 ).
- the plate 300 is moved upwards in the direction E by the ear 14.
- the operation plate 300 which is situated with the stop edge 301 at a distance below the turned end 156 of the bolt plate 150, is able to move upwards freely.
- the dead bolts 160 are then not yet extended.
- the stop edge 301 will indeed contact the turned end 1 56 of the bolt plate 150 which turned end is then situated lower.
- the operation plate 300 has the inclined orientation shown in figure 6 , and will when moving upwards in the direction E, driven by ear 14, take the turned end 156 upwards along with it. As a result the bolt plate 150 will also go upwards, and thus the pin 151 (and also the espagnolette plate 155) will go upwards as well, due to which the hooked bolt 160 and also the other hooked bolts, are retracted.
- both the latch and the hooked bolts can be retracted.
- the dead bolts need not be unlocked by means of a key.
- the lock assembly according to the invention has an additional facility, by which means unlocking from the inside by moving the lever handle 100 downwards, can be prevented.
- This facility can be used when the residence is left unattended for some time, for instance during the holidays. A burglar that may for instance have entered the house through a window, then cannot use the door for removing the objects from the house.
- the sliding plate 330 is provided, which is reciprocally slidable in the direction G, positions shown in figures 8A and 8B .
- the cylinder lock (profile cylinder) 400 lies with cam 401 in a vertical plane with the aforementioned edges 331-333 and 328, as a result of which when operating with a key of the lock 400, the key being turned in the direction F, the cam slightly lifts the plate 320 and subsequently, due to abutment against the edge of the recess 332, will urge the plate 330 to the left as seen in the drawing.
- the pin 335 that is attached to the plate 330 and extends in the vertical slot 303 in the operation plate 300, takes the upper end of the plate 300 along to the left, until the cam 401 is rotated beyond the edge 333. With the sliding of the plate 330 the slot 337 is also shifted, wherein the pin 221, which is fixed to plate 220, which plate is biassed in downward direction by means of spring 341, is lifted by the lifting forces exerted by the cam 401 on the lower edge 222, from the receiving space 334. The pin 221 has thus also left the receiving space 322.
- the pin 221 is then released from the recess 338, and during moving the plate 330 towards the left (G), due to the rotation of the cam 401, the pin 221 will (relatively) run through the slot 337, in order to finally end up in front of the recess 338.
- the permanent pin 190 runs in slot 336.
- the pin 221 is pressed into the receiving space 338 by the spring 341.
- the pin 221 has thus also ended up in the receiving space 223.
- the given position of the sliding plate 330 is locked, and thus the position of the upper end 301, 302 of the operation plate 300 in the position of figure 8B .
- the operation of the outer lever handle 110 in downward direction C may have the same result as the operation of the inner lever handle 100 in the same direction.
- the follower part 50 takes along the outer follower plate 60 in the direction C, wherein the cam surface 64 abuts the cam surface 22 of cam 21.
- the first lever handle plate 20 is co-rotated, but it can be decided whether the second lever handle plate 10 has to be co-rotated as well, and thus separately, via ear 14, the bolt plate 150 has to be moved upwards in order to retract the hooked bolts 160.
- the coupling plate 90 is tiltably attached on the second lever handle plate 10.
- the coupling plate 90 is tiltable about the pin 16 and is provided with a stop end 91 and a lip-shaped operation end 92.
- the lip 92 is in contact with the bent edge 241 of the lower portion 240 of the sliding plate 220.
- the plate 220 is biassed downwards.
- the edge 241 presses against the lip 92, due to which, as can be seen in figure 7B , a moment in the direction I is exerted on the coupling plate member 90.
- the stop 91 remains out of reach of the lip 26 which is integrally formed to the first lever handle plate 20. Rotation of the first lever handle plate 20 will then not result in corotation of the second lever handle plate 10, and by operating the outer lever handle 110 neither the latch 170 not the dead bolt 160 can be retracted.
- the cam 401 When as indicated in figure 7A , the cam 401 is moved in the direction H using the key in the lock 400, the cam 401 will abut the shoulder 321 a so that the tilting plate 320 is tilted upwards. As a result the pin 221 is slightly lifted, from the first receiving space 322 and will come to support on the elevation or ridge 229. The tilting plate 320 then takes up a tilted position, counter the force in the compression spring 344. Pin 221 is then clamped between the ridge 329 and the spring arm 342b, but the tilting plate 320 cannot tilt back as a result of the orientation of the aforementioned edge of the ridge 329.
- the key can then be turned back (the cam cannot be rotated further, due to the presence of the edges of the sliding plate 330), and be taken out.
- the tilting plate 320 keeps the (stable) position of figure 7A . In that position the plate 220 is moved slightly upwards, so that the bent edge 241 moves away from the lip 92. Thus room is created for -spring-biassed-rotation of the member 90, so that the stop 91 comes into engagement with the lip 26.
- the outer lever handle can be operated with the same hand as used to operate the key. Rotation of the lever handle 110 in downward direction C in that case indeed results in corotation of the second lever handle plate 10, and via ear 14, in upward movement of the bolt plate 150, and thus in retraction of the latch and the hooked bolt 160, if they were extended.
- the tilting plate 320 After opening the door the tilting plate 320 remains in the tilted position. In order to have the tilting plate 320 tilt back again, the lip 304 will abut the cam 320d when moving the plate 300, so that the tilting plate 320 is urged aside then, wherein the pin 221 moves away from the ridge 329 towards the first recess 322. A similar cooperation exists between the edge 325 of the tilting plate 320 and the turned end 156 of plate 150.

- Preferably the lock assembly is provided with means for cancelling the locking, particularly with a cylinder lock (profile cylinder, such as Europrofile), of which the cam is part of the means for cancelling the locking.
- The placing of the cylinder lock (profile cylinder, such as Europrofile) and the first coupling plate and/or the means for cancelling the locking preferably is such that the cam is operative in there in an upper part track of the circumferential path of the cam.
- The second connection means preferably are permanently operative.
- Furthermore third coupling means may be provided for bringing the fourth connection means in and out of operative coupled condition, so that the latch is not operated for retraction.
- In a simple embodiment the second and third coupling means are at least partially similar.
- Preferably the first coupling means are also operative in bringing the sixth connection means in and out of operative coupled condition and preferably are also in series with the second coupling means. Thus a double security is obtained against unauthorised operation of the dead bolts.

Thecircular portions closing rings 80a, 8b. - The first
lever handle plate 20 has anarm 24 having an integrally formed and perpendicularly turnedoperation lip 25. At a location almost diametrical to thearm 24, the firstlever handle plate 20 is furthermore provided with an integrally formed and perpendicularly turnedoperation lip 21, which is provided with astop surface 22. The firstlever handle plate 20 is provided with perpendicularly turnedlips - The second
lever handle plate 10 is provided with anoperation cam 13 formed in the same plane, as well as with anattachment pin 16, which will be mentioned further below, and anear 14 shifted from and parallel to the plane of thelever handle plate 10, which ear has ahole 15. Furthermore a turnedlip 17 is integrally formed to the secondlever handle plate 10. - As indicated in the
figures 1 and2 thepin 16 serves to attach acoupling catch 90, which is provided with an operation lip 92 alip 93 and astop end 91, of which the function is yet to be described. By means of a spring that is not shown, thecoupling catch 90 is biassed towards a position extending into the path of motion oflip 26, for engagement therewith. - The
inner follower plate 30 is provided with acam 32 on which on the onehand stop surface 33 is provided and on the other hand aninner stop surface 34 and anouter stop surface 35 are provided. At the diametrical opposite side acam 36 is formed, havingstop surface 37. Acam 38 havingstop surface 39 is also formed there. - In a comparable manner the
outer follower plate 60 is provided with acam 62, havingstop surface 63 and stopsurface 64 facing in counter direction, and diametrically opposite it with acam 65 havingstop surface 66 and acam 67 havingstop surface 68. In radial direction thecam 62 extends just as far as thesurface 34. The cam therefore describes a larger path than thecam 62. - The outer

Thecam 62 is situated in the path of rotation of thelip 72, which is bent out of the material of thelever handle plate 70 and is also situated in the path of rotation of thelip 21. - Likewise the
cam 32 extends within the path of rotation of thelip 72 and furthermore within the path of rotation of thelip 21 as well as of thelip 11. - In general diametrically opposite lips or cams having stop surfaces are used in optimising the transmission of forces during rotation.
- In the
figures 3A-C andfigures 4A-C the lever handle/follower assembly offigures 1 and2 is assembled and shown in various views. The situations are different to such an extent, however, that in thefigures 3A-C thecoupling catch 90 extends in the path of thelips stop end 91 and thus a motion coupling is present between thelever handle plates figures 4A-C . In thefigures 4A-C , as a result, as will be further explained, when rotating thefollower 50, a corotation of the firstlever handle plate 20 but not of thelever handle plate 10, is realised so that thecam 13 and theear 14 remain in their places, as considered in direction of rotation. The lever handleplate 70 furthermore remains in its place as considered in direction of rotation. - The
figures 5 and further show an assembly that substantially corresponds with the assembly of the previous figures accommodated in a lock case, in a door, particularly a front door of a house or the like. - A
lock assembly 2 according to the invention is accommodated in thefront door 5, the lock assembly having a lock case or housing formed bywalls figures 5 and further have been accommodated. - The lock assembly comprises a
latch 170, arranged on apin 171, having astop 172. Thelatch 170 is spring-biassed into a projecting position, extending beyond thelock plate 6. - The
lock assembly 2 is furthermore provided with adead bolt 160, that is rotatable about fixedpin 161 and is provided with aslot 162 and ahook 163. In the slot 162 a pin 151 (seefigure 5 ) is accommodated, whichpin 151 is permanent tobolt plate 150 that can be slid up and down. Thebolt plate 150 is slightly shorter than the distance between thewalls bolt plate 150 is provided with turned ends 156, 159, and formed as one unity withvertical strips 155, which form a connection that is not further shown with other dead bolts, which are accommodated in a manner that is not shown in thedoor 5. - Parallel to the
bolt plate 150, anoperation plate 300 is arranged, which is also strip-shaped and hinged to theear 14 of the secondlever handle plate 10 by means of a pin passed through thehole 15. The upper end of theoperation plate 300 is provided with avertical slot 303, in which apin 335 which will be further discussed is accommodated in a manner so as to be slidable up and down. In addition theoperation plate 300, as seen in the drawing on the left-hand side, is provided with a downward turnedlip 302. The upper edge of theoperation plate 300 forms astop edge 301. Aninclined edge 304 is furthermore provided near the upper edge. - A
torsion spring 180 is furthermore shown, which is permanent to the lock case, and abuts the turnedlip 25 with thearm 181, as can be seen infigures 5 and6 . - As can be seen in the
figures 5-9 , a slidingplate 220 is provided below theoperation plate 300, which sliding plate at the lower end 240 is provided with anpilot edge 241. Thepilot edge 241 is in contact with the turnedlip 92 of thecoupling catch 90. At the broadened upper end of the sliding plate 220 a transversely projectingpin 221 is attached, which extends in aslot 337 of a slidingplate 330. The slidingplate 220 is vertically movable. The slidingplate 220 is then guided by thepermanent pin 190 extending in the verticalelongated hole 223 of the slidingplate 220 and by thepermanent pin 191 extending in theslot 224. Thepin 221 and thus theplate 220 is pre-biassed downward by atorsion spring 341, which is provided with twoarms wall 3a of the lock case and theother arm 342b supports against thepin 221. - The sliding
plate 330 is slidable in the direction G (among othersfigure 8A ) and at the lower edge is provided with a run-in edge 331, arecess 332 and a run-out edge 333. At the left end theslot 337 has arecess 334 and at the right end it has arecess 338. In those recesses, and also in theslot 337, thepin 221 extends, which as already stated, is permanent to the slidingplate 220. - At the left-hand side, the sliding
plate 330 is furthermore provided with aslot 336 opening towards the clear of the frame and into which apin 190 extends which is permanent to the lock case. - The sliding
plate 330 is furthermore provided with ahorizontal slot 339, into which apin 327 extends, which is permanent to the lock case, and around which thetorsion spring 341 is arranged. Apin 335 is permanently attached on the slidingplate 330, whichpin 335 extends into theslot 303 ofplate 300. - Furthermore (as seen in the drawing -
figure 7A ) atilting plate 320 is situated above the slidingplate 330, which tilting plate can be hinged about apin 500 that is permanent to the slidingplate 330 and which is provided withhole 328 into which thepin 335 of the slidingplate 330 extends with play. The tiltingplate 320 thus is tiltable with respect to the slidingplate 330. The tiltingplate 320 at its right upper end is provided withlip 320a, to which an end of acompression spring 344 is attached. With its other end thecompression spring 344 is attached tolip 343 of slidingplate 330. At the left upper end of thetilting plate 320 acam 320d is provided, which may lie in the path ofedge 304 ofplate 300. At the opposite side of thetilting plate 320, top left, anabutment edge 325 is provided. At the side facing the cylinder lock (profile cylinder) 400, the tiltingplate 320 is provided with ashoulder 321 a, and above it with aconcave edge 321 b. At the opposite side the tiltingplate 320 is provided with aslot 324 in which afirst receiving space 322 and asecond receiving space 323 are provided, separated by aridge 329. The edge of theridge 329 facing the receivingspace 323, is oriented such that it may exert a clamping action on thepin 335, in the situation shown infigure 7A . - The operation of an exemplary embodiment of the lock according to the invention will now be discussed.
- When (see
figure 1 ), in this case, the lever handle 100 placed at the inner side of the door is pivoted upward in the direction A its square top 101 will co-rotate thefollower part 40. Thefollower part 50 remains in its place. Due to thehexagonal edge 41 of thefollower part 40 which engages into the hexagonal hole 31 offollower plate 30,follower plate 30 is co-rotated in the direction A. Thus, thecam 32 is also rotated, and thus thestop surface 33 on it. Thissurface 33 abuts surface 73 onlip 72 of outerlever handle plate 70, which co-rotates and thus thecam 74 which presses against thestop 158 of theplate 150. As can be seen infigure 9 thebolt plate 150 is thus urged downward in the direction B into the position shown infigure 9 . Thecam 151 is thus also urged downward. Thecam 151 is thereby moved withinhole 162 of hookedbolt 160, as a result of which this hookedbolt 160 is rotated about fixedhinge point 161 into the extended locking position shown infigure 9 . Thebolt plate 150 is connected to hooked bolts that are not further shown and arranged in the lower portion of the door by anespagnolette plate 155 that is common per se. These hooked bolts are extended in a manner that can be compared with hookedbolts 160. - The latch is not operated here.
- When the lever handle 100 situated at the inner side is turned downwards in the direction C, the lever handle will rotate the
follower part 40 in the direction C. Thefollower part 50 here remains in its place. Here too, theinner follower plate 30 is taken along, in opposite direction, and thus thecam 32 as well, which withcam surface 34 then abutscam surface 22 ofcam 21 on the firstlever handle plate 20 in order to co-rotate it in the direction C. Theplate 70 here remains in its place. - Due to rotating the
lever handle plate 20, tension is built up in thespring 180 as a result of thecam 25 abuttinglip 24 againstprotrusion 181 ofspring 180. Comparefigures 5 and6 . Due to abutment of thecam surface 35 on theinner follower plate 30 againstcam surface 12 ofcam 11, the secondlever handle plate 10 is also co-rotated and thus thecam 13 is also co-rotated, which cam abuts theabutment plate 172 at the end ofbolt pin 171 oflatch 170, wherein thelatch 170 is retracted in direction D, as can be seen infigure 6 . - With the second
lever handle plate 10, theear 14 that is integrally formed therewith in a shifted manner, co-rotates, and which by means ofhole 15 andpin 301 is hinged to the elongated operation plate 300 (seefigures 5 and6 ). Theplate 300 is moved upwards in the direction E by theear 14. - In the
figures 5 and6 theoperation plate 300, which is situated with thestop edge 301 at a distance below the turnedend 156 of thebolt plate 150, is able to move upwards freely. Thedead bolts 160 are then not yet extended. - When the dead bolts are indeed extended, the
stop edge 301 will indeed contact theturned end 1 56 of thebolt plate 150 which turned end is then situated lower. Theoperation plate 300 has the inclined orientation shown infigure 6 , and will when moving upwards in the direction E, driven byear 14, take the turnedend 156 upwards along with it. As a result thebolt plate 150 will also go upwards, and thus the pin 151 (and also the espagnolette plate 155) will go upwards as well, due to which the hookedbolt 160 and also the other hooked bolts, are retracted. - Thus by operating the lever handle 100 from the inside, by moving it in a usual opening manner, both the latch and the hooked bolts can be retracted. In case of fleeing a residence the dead bolts need not be unlocked by means of a key.
- The lock assembly according to the invention, however, has an additional facility, by which means unlocking from the inside by moving the lever handle 100 downwards, can be prevented. This facility can be used when the residence is left unattended for some time, for instance during the holidays. A burglar that may for instance have entered the house through a window, then cannot use the door for removing the objects from the house.
- This is achieved by bringing the
operation plate 300 with the turnedlip 301 in front of theslot 157 in turnedend plate 156. Upward direction in E of theoperation plate 300, by operating thelever handle 100, can then take place without thetransverse plate 156 is taken along upwards. Theplate 300 can then move to the position shown infigure 8B . The operation of the hooked bolts therefore remains left undisturbed, and the hooked bolts remain extended. - For the positioning of the
operation plate 300 needed to that end, the slidingplate 330 is provided, which is reciprocally slidable in the direction G, positions shown infigures 8A and8B . The cylinder lock (profile cylinder) 400 lies withcam 401 in a vertical plane with the aforementioned edges 331-333 and 328, as a result of which when operating with a key of thelock 400, the key being turned in the direction F, the cam slightly lifts theplate 320 and subsequently, due to abutment against the edge of therecess 332, will urge theplate 330 to the left as seen in the drawing. Thepin 335 that is attached to theplate 330 and extends in thevertical slot 303 in theoperation plate 300, takes the upper end of theplate 300 along to the left, until thecam 401 is rotated beyond theedge 333. With the sliding of theplate 330 theslot 337 is also shifted, wherein thepin 221, which is fixed toplate 220, which plate is biassed in downward direction by means ofspring 341, is lifted by the lifting forces exerted by thecam 401 on thelower edge 222, from the receivingspace 334. Thepin 221 has thus also left the receivingspace 322. Thepin 221 is then released from therecess 338, and during moving theplate 330 towards the left (G), due to the rotation of thecam 401, thepin 221 will (relatively) run through theslot 337, in order to finally end up in front of therecess 338. During this sliding thepermanent pin 190 runs inslot 336. Thepin 221 is pressed into the receivingspace 338 by thespring 341. Thepin 221 has thus also ended up in the receivingspace 223. The given position of the slidingplate 330 is locked, and thus the position of theupper end operation plate 300 in the position offigure 8B . When theinner lever handle 100 is now operated, to rotate theear 14 upwards, to move theoperation plate 300 upwards in the direction E, said turnedlip 302, in the position shown infigure 8B , will move through theslot 157, wherein thebolt plate 150 remains in its place. - When unlocking this facility again, when the residents will stay in their house for a longer period again, the key of the
lock 400 is operated in opposite direction, so that thecam 401 moves in the direction H. Here thecam 401 rotatespast edge 333 of the slidingplate 330 against theedge 222, as a result of which theplate 220 and thus thepin 221 is lifted and the slidingplate 330 is taken along to the right again. Thelip 302 then no longer is in front ofslot 157, so that an upward movement of theoperation plate 300 results again in the taking along of thebolt plate 150, so that the hookedbolts 160 can be retracted again when moving the lever handle 100 down. - From the outside, operation of the
lever handle 110, the operation of the lock according to this exemplary embodiment of the inventions is as follows. - When rotating the outer lever handle 110 in upward direction A, the
follower part 50 is co-rotated, and due to inter-engagement of thehexagonal edge 51 inhexagonal hole 61 thefollower plate 60 is co-rotated. Thus thecam 62 is co-rotated, so thatplane 63 abuts surface 73 ofcam 72 onlever handle plate 70. - As a result the
bolt plate 1 50 is pressed downwards, and the hookedbolts 160 will be extended as described before. - In principle the operation of the outer lever handle 110 in downward direction C may have the same result as the operation of the inner lever handle 100 in the same direction. The
follower part 50 takes along theouter follower plate 60 in the direction C, wherein thecam surface 64 abuts thecam surface 22 ofcam 21. Thus, in principle, the firstlever handle plate 20 is co-rotated, but it can be decided whether the secondlever handle plate 10 has to be co-rotated as well, and thus separately, viaear 14, thebolt plate 150 has to be moved upwards in order to retract the hookedbolts 160. - For said coupling the
coupling plate 90 is tiltably attached on the secondlever handle plate 10. Thecoupling plate 90 is tiltable about thepin 16 and is provided with astop end 91 and a lip-shapedoperation end 92. Thelip 92 is in contact with thebent edge 241 of the lower portion 240 of the slidingplate 220. By means of thespring 341 which is effective on thepin 221, theplate 220 is biassed downwards. Thus also theedge 241 presses against thelip 92, due to which, as can be seen infigure 7B , a moment in the direction I is exerted on thecoupling plate member 90. As a result thestop 91 remains out of reach of thelip 26 which is integrally formed to the firstlever handle plate 20. Rotation of the firstlever handle plate 20 will then not result in corotation of the secondlever handle plate 10, and by operating the outer lever handle 110 neither thelatch 170 not thedead bolt 160 can be retracted. - When as indicated in
figure 7A , thecam 401 is moved in the direction H using the key in thelock 400, thecam 401 will abut theshoulder 321 a so that the tiltingplate 320 is tilted upwards. As a result thepin 221 is slightly lifted, from thefirst receiving space 322 and will come to support on the elevation or ridge 229. The tiltingplate 320 then takes up a tilted position, counter the force in thecompression spring 344.Pin 221 is then clamped between theridge 329 and thespring arm 342b, but thetilting plate 320 cannot tilt back as a result of the orientation of the aforementioned edge of theridge 329. The key can then be turned back (the cam cannot be rotated further, due to the presence of the edges of the sliding plate 330), and be taken out. The tiltingplate 320 keeps the (stable) position offigure 7A . In that position theplate 220 is moved slightly upwards, so that thebent edge 241 moves away from thelip 92. Thus room is created for -spring-biassed-rotation of themember 90, so that thestop 91 comes into engagement with thelip 26. Now the outer lever handle can be operated with the same hand as used to operate the key. Rotation of thelever handle 110 in downward direction C in that case indeed results in corotation of the secondlever handle plate 10, and viaear 14, in upward movement of thebolt plate 150, and thus in retraction of the latch and the hookedbolt 160, if they were extended. - After opening the door the tilting
plate 320 remains in the tilted position. In order to have thetilting plate 320 tilt back again, thelip 304 will abut thecam 320d when moving theplate 300, so that the tiltingplate 320 is urged aside then, wherein thepin 221 moves away from theridge 329 towards thefirst recess 322. A similar cooperation exists between theedge 325 of thetilting plate 320 and theturned end 156 ofplate 150. - When in case of an extended sliding
plate 330 due to a revolution of thecam 401 of thelock 400 theplates operation plate 300 cannot be operative, that situation will first have to cancelled by a full revolution of the cam. This is therefore the case when the so-called holiday position is used. Usually a partial revolution of thecam 401 will suffice, in order to subsequently lift 324, which facilitates the operation of the lock assembly from the outside to the resident.
