Then will cooperate Figure 10 other embodiment of the present utility model to be described, will represent with identical reference number with the explanation of front and Fig. 1 corresponding spare part in Fig. 9 in it, and it will can not do further explanation to Figure 19.Moreover, corresponding haply with person noted earlier, but being a large amount of revisers, also all will represent, but it can add 100 with its original reference number with identical reference number.

Lock bolt driving sector ele-ment 56 is replaced by lock bolt driving sector ele-ment 156 in the content counting down, lock bolt drives connecting piece 46 and drives connecting piece 146 replacements by lock bolt, link component 31 is replaced by link component 131, barrier element 35 replaces (135a is driven by springs) by barrier element 135, and dead bolt 41 is replaced by dead bolt 141.

This embodiment comprises that also a kind of different arrangement can be for the upper and lower dead bolt of operation (he also can operate in the middle of dead bolt), and a kind of different mechanism can utilize key operated and can unblank from the door that this lockset is installed or " outside " of window.Yet its explanation will at first be done explanation at key operated center latch mechanism.

The spare part of this kind improvement marks in Figure 17, and wherein reference number a is that the lock bolt that marks improvement respectively drives sector ele-ment 156 to b, and lock bolt drives connecting piece 146, dead bolt 141, barrier element 135 and link component 131.Barrier element 135 is pushing top spring 135a under cam, but it then can back be promoted by spring after breaking away from cam.

Lock bolt drives connecting piece 146 and still has a cutting part 51, and the ccontaining cam 54 of locking tube orders about lock bolt driving connecting piece 146 and does linear reciprocating motion when the lock tube rotates.Yet it is different that its this linear movement is sent to mechanism's desire of dead bolt 141, and its difference is to be that its major part can be got by oneself a kind of effect of continuous growth distance when lock bolt drives the key operated action of connecting piece 146.When comparing with lock bolt driving connecting piece 46, it can provide two-part action, wherein first is line movement, directly drives the dexter groove 47 of connecting piece 46 and the dowel pin 44 that dead bolt 41 is given prominence to via lock bolt, and directly drives to dead bolt 41.Second portion then is that lock bolt drives connecting piece 46 (nationality is by the coupling mechanism between dowel pin 59 and the groove 49), does the pivoting action and can order about sector ele-ment 56, makes it to apply an extra line movement by dowel pin 58 and 45 pairs of dead bolts 41 of groove again.

In this embodiment the inside, this process improved sector element 156 has tail end 160 and is directed to and can orders about sector ele-ment 156 is done pivoting with respect to dowel pin 59 action, therefore it can directly be sent to dead bolt 141 with line movement via dowel pin 58, and wherein this dowel pin 58 is the grooves 45 (seeing Figure 17 c) that are engaged on dead bolt 141.But, tail end 160 has a wheel hub 160a can be by the guiding of the groove 160b in the guide plate (seeing Figure 18 c and 18d), make when initial rotation this during by the operated lockset of key, lock bolt drives connecting piece 146 and can be moved by cam 58, the tail end 160 that he also can order about sector ele-ment moves towards the front 161 of housing, and meeting is meshed fast and its membership can be sent to line movement dead bolt 141 places by the guiding of wheel hub 160a.

Therefore it have a kind of effect of the distance that almost doubles immediately, and wherein the locking of this dead bolt 141 action is better than the direct transmission of the line movement that is driven connecting piece 146 quilts by cam 58 lock bolt that drives.Moreover it will apply a kind of very smooth-going driving force to this dead bolt.

Figure 18 a and b have marked the sector ele-ment 156 and the dead bolt 141 of polising, and he demonstrates the position and the locking position of not locking respectively.He now shows the linear reciprocal action of dead bolt 141, and when this lockset when key operated, the slip of this sector ele-ment 156 and pivoting composition action.

This sector ele-ment through redesign can be so that the entire depth of housing reduces (its degree of depth is that the front surface 161 perpendicular directions of employing and housing are measured) with relevant spare part, he compares to the housing shown in Fig. 9 with Fig. 1, and its advantage is to be that it can be for lockset and housing that various different types are installed.

The structure of barrier element 135 is similar to barrier element 35 haply, and difference has been recess 136 and cam face 139.

Link component 131 also is similar to link component 31, but when comparing with the recess 32 of link component 31 and bossy body 55, its recess 132 has different shapes with bossy body 155; With and have a kind of different two shaft types drive assembly can be for driving up knob disk 112 (see shown in the reference number 171 and 172 of Figure 14 and Figure 15, will narrate in more detail thereafter).When lockset by key operated when being line movement and being sent to link component 131, the disk 121 of last axle 171 can be rotation pivotally, so that can have the latch head 103 of spring ejection to do the action of unblanking to one under the operation of key, it only can be by the outside operation of window that is provided with lockset or door.

To cooperate Figure 11 a and 11b (wherein some spare part is omitted) and Figure 12, Figure 13 more detailed description below.

Figure 13 has marked lockset and has been positioned at the not position of locking, it is its this lockset has been done part toward the direction of unblanking operation, so that can with the dead bolt 141 of centre and up and down dead bolt do the action unblanked (it will do more detailed description as the back) simultaneously, but, because the inside of lockset must be designed modestly, make the outer handle method be installed on the axle 171 do unlocking action, he is that this link component 131 and this have the synthetic new assembly of operating mechanism of the latch head 103 of spring ejection, will narrate as after.

Link component 131 has a hook end 162, (Figure 17 e, Figure 12 and Figure 13), he can nibble dowel pin or other bossy bodies 163 of axle disk 112, when last unblanking to rotate and link component is done linear when moving (towards the right-hand side of Figure 13) in that cam path is done, disk 112 can be docile and obedient clockwise and be turned to the not position of locking shown in Figure 12.This disk 112 has the inclined cam surface 165 that a nose 164 is nibbled a sliding part 166, and the direction that this sliding part can the some and latch head 103 in housing be done reciprocating action is made the line movement of vertical direction.

Must be noted that unblanking at last during action of lock tube, the linear reciprocal action of this latch head 131 is only done with respect to pivot 163 that counter-clockwise direction is rotated and could be moved when reaching the position that Figure 13 do not lock at link component 131.The action of this link component 131 is only being unblanked, and promptly utilizes key unlocking, and with dead bolt 141 withdrawal of centre and utilize just like a kind of mechanism shown in Figure 19 figure up and down dead bolt could move after unblanking, this mechanism will be described further as after.

Get back to the action that Figure 12 opens from the lockset outside, sliding part 166 can be under the effect of axle disk 112 pintle movements and be the right-hand side that linearity moves to Figure 13, and it can offend and disobey with rude remarks the elastic pressure of compression spring 168.Must be noted that, sliding part 166 has the superficial degree of depth (this degree of depth be the linearity along latch head 103 move back and forth the path measure), with and make the distal portion 167 of a projection of housing have the corresponding degree of depth of dwindling, lockset and shell housing that they can the various different kenels of easier installation.Shell housing unit 167 is designed so that also sliding part 166 can do linear shift action.

Therefore spring 168 can drive the position latching place that sliding part 166 arrives Figure 13, but when it need open latch head 103, it can be opened, as shown in figure 12.

For the linear slide action of sliding part 166 being translated into the vertical reciprocal action of latch head 103, this sliding part 166 can be provided with a cam groove 169 that tilts, can mesh with a bossy body 170 at 103 1 inner nose bars of ccontaining latch head position, it can order about sliding part 166 and move right from the position of Figure 13 is past, and therefore it can order about the not locking position that latch head 103 moves to Figure 12.If necessary, it can be arranged to opposite shape with the shape and the assembly of latch head 103, so that opposite operation lockset can be provided.

Therefore, can only utilize when unblanking outdoors key operated just can, and he also need just can reach the purpose of unblanking according to a definite sequence.It provides an extra security feature, when not pinning even this door just latches, when promptly latch head 103 is positioned at the position that fastenes, unblanks also to utilize key to operate from the outside, no matter whether this centre dead bolt is lockable all the same with last and following dead bolt.

On the contrary, for breech lock is opened in the inboard, latch head 103 can be operated by internal handle and be moved to the position of retraction, wherein this internal handle is arranged on the axle 171, and it can directly be opened breech lock by the corresponding shift action of the rotation of disk 112 and sliding part 166 and latch head 103.

See it from the outside of lockset, it has an outer handle, be installed on the lower shaft 172, but the operation of this outer handle can't be carried out any action of releasing to latch head 103.

Figure 11 a and 11b are corresponding Figure 12 and 13 substantially, but have dispensed certain some spare part in the lockset, and particularly link component 131, so that can more clearly represent its structure.

Though certain some client prefers the outside and internal handle all are contained on the same axle, and its right hope can utilize outer handle to open breech lock from the outside, the lockset that is marked in Figure 19 at Figure 10 all is a kind of two-axis lock ( spool 171 and 172).In such cases, interior and outer handle will be installed on the axle 171, and can omit need not for this lower shaft 172 (lower shaft at this will for unnecessary).Though this kind structure is clearly more dangerous, because it is preferred to use by some client, so it still can be accepted, and it will only rely on dead bolt and go to prevent that other people from invading.

Shown in Figure 10, it will narrate a kind of a kind of mode of operating upper and lower dead bolt except middle dead bolt 141 especially.Clearly, make that when all dead bolts all can be operated, it can provide a kind of very safe locking and fastening system, he has three dead bolt bossy bodies that separate, and is positioned at the locking position place.And from the enclosed planar of lockset outward one suitably distance enter into home in the fixing tank bracket, the door of the utility model lockset or window wherein are housed are mounted in this fixedly inside the tank bracket.This kind structure provides a kind of very safe configuration, he can resist effectively any from door or window the outside and also use a kind of beaing or other instruments and the situation desiring to open by force.

With Fig. 1 to the embodiment of Fig. 9 differently, the mechanism that is used for operating upper and lower dead bolt comprises a single drive track, it only can move towards a direction, so that operate this two upper and lower dead bolt.This drive track is to be the exploded view shape in Figure 10, but reference number 173.Drive track 173 can be done linear moving by Internal handle or outer handle operation, because axle 171,172 and drive track 173 connect each other to some extent.Drive track 173 can move to the left-hand side of Figure 19, so that upper and lower dead bolt is pinned, it is turned right and then this two dead bolt can be opened.Figure 19 has marked the situation that interconnects of a cam groove and slip dowel pin, this upper lock tongue 174 promptly connects mutually with this coupling mechanism, comprise cam groove 175 and bossy body 176, and one is similar haply but inside desiring to be arranged on down dead bolt toward the cam groove that rightabout tilts.Figure 19 marks the not position, position of locking of dead bolt 174 with solid line, wherein dowel pin 176 is the bottoms (also representing with solid line) that are positioned at cam groove 175, the dotted line of cam groove 175 then marks the locking position of this driver, wherein this dead bolt bossy body is the end opposite that occupies this cam groove 175 now, and he represents with reference number 176 '.

Figure 16 a and Figure 16 b mark spool an actuating arm 171a and a 172a respectively, and it can rotate about 40 degree, and can start between the actuating of upper and lower dead bolt and unactuated position.Its pivotal action up can be limited by a screw rod; Helical spring 177 provides a kind of ejector apparatus, and can after the upper and lower dead bolt of these handle operations each handle be returned to horizontal level.

Figure 10 has marked the exploded view of drive track 173 with respect to the shell housing, and Figure 14 and Figure 15 then mark drive track 173 and be positioned at combined location.It marks these actuating arms 171a, 172a in addition and drive track 173 is the cam-type combinations that are slip, he is the roller 178 via the end that is installed in actuating arm 171a and 172a, and nationality is realized by the sliding action on the guiding plane of the cutting part 179 in drive track 173.

The teamwork of the various inner spare parts of lockset is dead bolt in the middle of making, only can could carry out with the action of unblanking and lock last and dead bolt down according to a scheduled operation operation in tandem, and any this order person that has no basis all can't operate, and so make key just can release after must finishing all programs of unblanking or locking according to required order.

For the lock out action of at least a portion, dead bolt 141 in the middle of it must want to operate independently, and the inside spare part of lockset is designed so that dead bolt 141 can move to not the position and the locking position of locking, and and any possible operational motion of other spare parts irrelevant fully.Yet if it is when needing in addition the upper and lower dead bolt of operation, its design, the particularly shape of drive track 173 for the operation spare part must be designed so that upper and lower dead bolt can only just can do the action of locking and unblanking according to predetermined operation sequence.Therefore, for an operational motion of locking, it at first must pin upper and lower dead bolt, it can be reached axle 172 by the effect of outer handle, via actuating arm 172a, the operational motion of the corresponding cutting part in roller 178 and the drive track 173 is reached, so that drive track is moved toward the left side of Figure 14; Or it can operate and act on axle 171, actuating arm 171a, the Internal handle at roller 178 and its corresponding cutting position (not marking among the figure) and reaching.It can be reached by each corresponding handle action up, it can mobile drive track 173, then when unclamping handle, each corresponding spring 177 can be returned to handle the position of level, but it can not make drive track do any displacement, fills and is permitted to reach because this action is space in each corresponding cutting position 179.After pinning upper and lower dead bolt, it can pin the dead bolt of centre, he is finished by the scope that shape allowed of drive track 173, but after the trimming locking action of middle dead bolt 141 is finished, and after key takes out in lock tube lockset, drive track 173 all can't move towards the direction that (upper and lower dead bolt) unclamps under the operation of any handle, because this of this drive track kind of mobile being blocked.

On the contrary, unblank in the program one (in the middle of supposing dead bolt and last and down dead bolt all be lockable), this lockset at first must partly be unblanked, so that with the withdrawal of middle dead bolt is a certain be enough to degree that drive track 173 unclamps till, this measure makes interior or outer handle all can down be operated, so that drive track can be moved the position, position (seeing Figure 19) of unblanking, it then can be returned to the position of level when handle unclamps, the operation that this kind unblanked then need be taken out key when finishing centre all actions of unblanking of dead bolt, is required to be it when operating this kind unlocking action in the outside at least.

When being unblanked, latch head 103 has similar situation, because link component 131 can arrive a certain position (not marking among the figure), wherein when lockset is driven into locking position fully, its front surface can closely be fitted along the front surface of housing, and after middle dead bolt is finished unlocking action, this link component only moves to the pivot location place that solid line marked among Figure 10, take this to make that the further rotational action of lockset and its cam can apply linear action to link component 131 via bossy body 155, it then can do the action of unblanking via hook end 162 as previously mentioned.

These lock bolts are penetrated bar 285,286 and also are connected to link component 221, and this connects element and then can be operated by the pin 237,238 of the slave arm 235,236 of driven member 231,232.If arbitrary driven member (is seen each accompanying drawing) by each handle when counter-clockwise direction is rotated, the slave arm 235,236 of its associating can move down.Pin 237,238 on each slave arm 235,236 will be with respect to each groove 223,224 toward moving down into its bottom, with and then can effectively link component 221 be moved down.This link component 221 shift action down can be linked to lock bolt by one and penetrate the suitable lever connecting piece (not marking among the figure) of bar 285 and directly be sent to down lock bolt and penetrate bar 286, can operate extra dead bolt as previously mentioned so that make these lock bolts penetrate bar.At the same time, the pin 225 of link component 221 can move down along the groove 228 of link component 226, make that it can serve as the rotational action that axle is done pivoting with pin 216, and it can move to flange 229 outside the mobile route of cam 262 in the bottom of lever 226.One is come loose when handle, and spring 246 or 247 can act on to the pin 243 or 244 of slave arm 241 or 242, so that handle is returned to its normal horizontal position place.

For with dead bolt 251 from Figure 23 the position of locking does not move to locking position shown in Figure 20 and Figure 24 the time, link component 212 at first must be moved down by arbitrary door knob, make dead bolt to nibble, and a general V-shaped groove 230 that is positioned at link component 221 tail ends can be positioned at the mobile route the inside of less important link component 264.One key then can insert lock tube 261 the insides and cam 262 can be rotated (seeing accompanying drawing) towards counter-clockwise direction.This cam at first can be nibbled barrier element 274 effectively, so that barrier element is lifted high effect with antagonistic spring 269, make the extending part 277 of horizontal expansion to surpass pin 255 by the act height, and this pin promptly can freely move along groove 275.Cam 262 then can enter into cutting part 258 the insides of main link component 254, so that can mobile effectively link component.Because pin 255,257 is engaged on groove 283,272 the insides of housing and cover plate 281 respectively, so main Connection Element 254 can only be along to moving towards header board 202.This kind of this link component 254 is from being sent to less important link component 264 via pin 256 to shift action, and it then can utilize pin 252 to be engaged on the relation of groove 266 the insides and can drive dead bolt 251.Because main link component 254 is only directly being driven 14 centimetres by cam, so further the reaching of dead bolt 251 from the less important link component 264 of the mobile needs of length direction.The pin 252 of dead bolt 251 is groove 266 the insides that are positioned at less important link component 264, it is the pivoting point place far away that is positioned at the less important link component of distance that its pin 256 with main link component 254 is compared, this main link component 254 is to be positioned at identical groove 266 the insides, make 40 of cam 262 spend and to order about pin 252 and do one 20 centimetres string shape displacement that therefore he make the locking distance of dead bolt 251 be about 20 centimetres to the rotational action of 50 degree.

The bottom of barrier element 274 is provided with a curved recess 273 and can rotates for the cam 262 of lock tube 261, makes that it can not interfere with this barrier element when this barrier element up rises to its suitable height.When the rotational action of cam 262 makes it surpass barrier element, spring 269 secondary action again itself.The pin 255 of main link component 254 can move to the left-hand side (seeing accompanying drawing) of groove 275 at this moment, and he is the end opposite place that is positioned at the extending part 276 of horizontal expansion.Spring 269 can down be driven barrier element to its original position effectively, makes pin 255 can nibble the extending part 276 of the horizontal expansion of groove 275, therefore makes that main link component 254 and dead bolt 251 all can't starts.

When less important link component 264 is moved by main link component 254 and when dead bolt 251 moved to locking position, can be engaged on vee-cut 230 the insides of link component 221, when being positioned at its lowermost shift position, link component can catch this link component.The situation that the pin 255 of link component 221 is nibbled the groove 228 of link component 226 can prevent that link component 226 from up being moved, it prevents that then any of breech lock assembly from moving, therefore it can lock at the locking position place, so that provide lockset one extra safety.At the same time, being positioned at the handle of being fixed on the axle that stretches into driven member 231 and 232 can't move, because this link component 221 can be stopped and can't move by this less important link component 264, makes that so dead bolt can be by locking at this locking position place.

This dead bolt is merely able to just can be moved to its not position of locking when a key being inserted lock tube 261 the insides and rotate (the being clockwise direction) rotation in the opposite direction of this cam 262.As previously mentioned, cam 262 at first can be connected barrier element 274 and it can be lifted the high also effect of antagonistic spring 269, makes the extending part 276 of horizontal expansion can be lifted high and disengaging pin 255.Cam 262 can move to cutting part 258 along the curved recess 273 of barrier element 274, until it is connected till the main link component 254.Link component 254 then can be acted on by cam 262 and back move, and when pin 255 when the groove 275 of barrier element 274 moves, the pivot 263 of less important connector 264 meeting housings is that axle rotates, and dead bolt 152 is retracted, and its displacement again horizontal displacement than this main link component 274 is long.At the end that laterally moves of this main link component 254 and when cam 262 has broken away from it, pin 255 can be positioned at the opposition side of the extending part 276 of horizontal expansion once more, cam can break away from barrier element 274, this barrier element then can be acted on by spring 269 and move down once more, make pin 255 can be connected extending part 277 the insides of the horizontal expansion of grooves 275, therefore main link component 254 of star and dead bolt 251 can be stuck once more and can't start.

In order to unclamp dead bolt, needs rotate arbitrary handle and link component 221 are up moved, and make driven member 231 or 232 can be docile and obedient clockwise in all accompanying drawings and rotate.The combining mechanism that pin 237,238 is combined in each groove 223,224 the inside can make link component 221 up move and dead bolt is retracted.At the same time,, order about this link component pin 216 and rotate, so that in can path flange 229 translating cams 262 of link component 226 lower ends for axle when the pin 235 of link component 221 groove 228 along link component 226 up moves., cam need be done further the up time direction now and rotate door-lock opening for from the outside, till it is connected the bottom of flange 229 and effectively flange and link component 226 is lifted height.This link component up can make lock bolt connect element 212 with shift action and up move, he is because pin 216 is engaged on the cause of hole 227 the insides, and the less important link component 207 that this main 212 up shift action can order about lock bolt is that axle rotates and can as previously mentioned lock tongue 203 be retracted with pin 218.Not only the pin tongue can be opened when screw key, he also can retract dead bolt and door can be opened.This key then can be back then is withdrawn the lock tube, makes cam 262 can break away from flanges 229.Spring 211 is then driven less important Connection Element 207 and is made its rotation, and lock bolt 203 is back moved to locking position and link component 212,228 can be moved backwards to following position.

Screw key or rotational fixation to the handle that this is engaged on 231 of the driven members all can will be opened in the Men Congmen.This door can only utilize key and open from the outside.Moreover, when door is pinned according to aforementioned manner by dead bolt, if it does not have the key all can't be from Men Nei or open door outdoors, can't start because link component 221 has been engaged on that the less important link component 264 of groove 230 stops, can't be rotated and be connected lock bolt and mainly connect element 212 and should go up driven member 231, because the pin 237 of slave arm 235 is engaged on due to the upper end of groove 223, as shown in figure 20.

For cover plate 281 is fixed to housing 201, so housing can provide a pair of dowel pin 287 of up stretching and having screw, 288, this cover plate 210 can be provided with the hole (not marking among the figure) that aligns, make cover plate can utilize screw (marking among the figure) and be fixed on the housing, this screw pass this cover plate hole and and the screw of dowel pin 287,288 be meshed.The pin 205 that cover plate 210 more provides a groove can connect lock bolt screw rod 204 for appearance, it can really make cover plate correctly align with housing, and it can be used for guiding lock bolt screw rod 204.Cover plate 281 and housing 201 also are provided with circular hole 291,292 can connect and locate driven member 231,232 for holding.At last, cover plate more is provided with the fin that recess can supply to be connected housing wall edge correspondence at its periphery, so that will be to make cover plate correctly to align with housing once more really.
