Description

A kind of lock with insetting key magnetized partly

The present invention relates to a kind of lock, especially relate to and a kind ofly insert and open with the local magnetized key card, and lock with function of generation lock by the independent of each latch fitting, wherein, the leading edge of key card drives a slide plate that is unclamped by magnetization system bolt, this slide plate is positioned on the reach position, and after key card was partly return, this lock was adjusted to open position.

EP-0241323A2 discloses a kind of lock of the type.Start-stop action usefulness on the fixing stretch section of shell side face is used for position in the reach of slide plate, this stretch section clamps hinged pawl subsequently with the bending member of slide plate side.After inserting key card, the control of this slide plate is that turn to wide of logical back key card realizes.When extracting key card, pawl is clamped buting iron, and the back-moving spring that is clamped on the slide plate can be worked, and simultaneously, makes pawl and stretch section break away from engagement.The displacement of slide plate enters latch fitting or breaks away from coupled position, and does not depend on that Men Shangyu should lock the make position of the built-in lock that connects.This just might allow to extract returning of key card and slide plate, and this is unsafe, for example: being latched in fully forward locking or being on the centre position of danger alleged in the insurance technology when withdrawing fully backward of built-in lock.

Therefore, task of the present invention is that above-mentioned defective lock is done following improvement with comparatively simple production technology, and key card only could be extracted out when corresponding latch fitting is in the breech lock endpoint location.

For realizing above-mentioned task of the present invention, the lock that can open with the insertion of local magnetized key card according to the present invention also has a locking device that stops key card and/or slide plate travelling backwards, and this device depends on the operating position of each latch fitting.

By above-mentioned design, significantly improved the safety value of above-mentioned defective lock, can not occur again by alleged " dangerous centre position " in the safety technics that exists the rod bolt of defective to cause in the design.According to the present invention, if corresponding latch fitting is in a centre position in the reach position of slide plate, locking phenomena will appear, this locking stops key card and/or slide plate to be return.Thereby remind the user to note, the locking end position of latching operation to regulation.Then, this key card just can insert in the hole from key card and extract.This shows that corresponding latch fitting or the latch component that connects with it have been in position latching.A favourable further architectural feature is, is provided with the locking-typed pin of key card in slide plate, plays locking device.After the locking, slide plate and the key card that is inserted in the slide plate all can not be return.This lock mode is impassable.When key card was pulled out, slide plate was on its home position all the time, this means that this locking device is in non-interlocking state.During this lock on design hotel door, this means that the extraction key card just makes this lock be in latch mode.Can be embodied in simply on the structure of lock in order to the means that realize the present invention's design, particularly move and clutch sleeve is set up a kind of pressure control relation between moving at slide plate.This clutch sleeve is arranged between operator handle and the operative pin.When key card inserted, this clutch sleeve was pushed along with moving of slide plate, and clutch sleeve and operating handle and operative pin are coupled to each other, and therefore, the rotation of operator handle also will drive clutch sleeve and operative pin and rotate.If clutch sleeve and operative pin mediate after locking rotation, then this slide plate is just locked and can not return.Returning of slide plate is mobile only just possible when clutch sleeve is in its corresponding home position.If force control by a hinged installation in lock housing, realize that along the arm of the lateral control of skateboarding direction this arm is stuck on the clutch sleeve rigidly, structure so of the present invention will show its superiority.When slide plate moved forward, slide plate drove this rigid arm, thus, clutch sleeve also be moved to operative pin and operator between coupled position on.If at this moment operator is rotating to a centre position with clutch sleeve, the positioning convex that stretches out on the clutch sleeve is just no longer aimed at the insertion mouth on the lock housing so.Like this, slide plate just can not be moving to travelling backwards, because positioning convex stops clutch sleeve to be return with the clutch sleeve locking, this locking is passed to slide plate itself by this rigid arm equally.As previously mentioned, key card is lived by locking-typed lock on this position.This locking-typed pin by one be contained in the slide plate, therefore move and self-regulating pin is configured for these additional functions in a hole of key card corresponding producing cost can remain on minimum level with slide plate, because have only a corresponding pin to be installed in the slide plate.This key card also must punching on corresponding appropriate location.This means: after key card injected the key card patchhole of lock, this pin was aimed at mutually with the hole.In the displacement process that begins subsequently, the pin that this profile is fit to embeds in this hole, also rests on the reach position of slide plate.When key card was extracted out, this slide plate was forced to drive by pin.The ending phase pin of extracting out at key card just leaves this hole.Because two ends of this pin are all tapered, enter control and throw off control and brought convenience to pin.Usually cotter length can stretch out the end of pin greater than slide plate thickness from slide plate.Return on the mobile position at slide plate, the blunted cone shape end of this pin is embedded in the blunted cone connected in star on the lock housing.After key card inserted and begins reach, the blunt tapering point of this of pin left the blunt cone tank on the lock housing, and another blunted cone shape end relative with it then puts in the hole of key card.If someone has selected a kind of key card, it does not have the hole on the position of regulation, though people also can insert key card, can not make the slide plate reach.Because the possibility of this pin skew loses, so this pin stops slide plate to carry out unauthorized preceding shifting movement.For pin is installed, optimal position is near the slide plate the opening of key card patchhole.What also will be illustrated this is, position that can be by changing pin and/or shape realize the another kind of modification of locking, and this pin can be used as code-locked conversion pin and packs into.In fact, have only use that the key card of respective aperture is arranged on assigned position, just can make the slide plate reach.A kind of modification of lock according to the present invention forces control not to be in when connecting cooperation position between operator handle and clutch sleeve, and the prevention slide plate is subjected to displacement along the direction of propulsion of key card.Have only when this clutch sleeve is in the home position of its regulation, slide plate just might be promoted and be subjected to displacement by key card.Also has another possibility, a locking device that stops slide plate to return promptly is set, it is characterized in that: this locking device is made of the prolongation of slide plate, this prolongation has a key projection, when latch fitting was in the tram, this key projection was embedded into along with the return movement of slide plate in the groove on the latch fitting.If this latch fitting is in a centre position, then slide plate can not be return fully.Therefore this key card also can not be extracted owing to the locking of locking-typed pin.This just reminds the user to note, operator handle and latch fitting must be placed on the position of regulation.This prolongation is made camber member and the key projection is arranged in the vault zone of the arcuate apertures of holding latch fitting, this all is favourable for structure design and stressing conditions.Thus, load can be introduced from the middle part.Along with the reach of slide plate, second key projection on this slide plate embeds in another groove of latch fitting, so people have realized inserting locking by the slide plate design.Equally, latch fitting is in the prerequisite that the home position of regulation is a key card promotion slide plate.In addition, the feature of another kind of remodeling lock is, this locking piece is made of a lever adjacent with slide plate, and this lever has a key projection.This key projection is embedded in the groove of latch fitting when latch fitting is in tram and slide plate and moves, and this lever inserts in the hole an auxiliary fixing member by the slide plate of key card control to emit from key card and makes it to be offset.If when inserting key card and reach slide plate, the key projection not with latch fitting on groove chimeric, will stop key card to be extracted so.This means that in this remodeling lock, this auxiliary fixing member plays the locking-typed pin of key card on slide plate reach position.Only under the situation of key projection and the correct location of groove, this auxiliary fixing member could insert in the hole from key card and be offset, and has removed the locking to key card.This shows: it is favourable that auxiliary fixing member is arranged on the spring-loading bar.If the spring load on this bar points to the lever direction, then realized extracting locking.Otherwise,, can also realize a kind of insertion locking if the spring load on this bar points to key card patchhole direction.This insertion locking is achieved in that promptly have only when latch fitting is in the home position of regulation, promotes the slide plate reach by key card and is only in the cards.

Accommodate a lock housing 9 in the inside of lock box 3, part 10, a middleware 11 and a cover piece 12 at the bottom of lock housing 9 has one.One with the reverse tongue 13 of patchhole 7 by drawing here, this tongue embeds in the groove 14 on middleware 11 tops 15 when the cover piece 12 that promotes to be buckled on the middleware 11.When middleware 11 usefulness aluminium were made, end part 10 and cover piece 12 were made of plastics.Be provided with a tabular slide plate 16 that is made of plastics equally between cover piece 12 and middleware 11, the wide side of this slide plate 16 is placed on the middleware 11.The spigot surface of opposed slide plate 16 is latch plate 17 of being made by brass.This latch plate 17 is contained in can not displacement in the cover piece 12.On the position latching of the lock shown in Fig. 4, the hole 17 on the latch plate 17 ' aim at the through hole shape support slot 18 of slide plate 16, magnetized shop bolt 19 is inserted in the support slot 18.A shop bolt 19 need be installed all in each support slot 18, because the number of shop bolt 19, position and polarity are to set according to the unlocking cipher combination of respectively overlapping of lock 1.

Have a prerotation vane 20 made from brass equally on the opposite side of locking plate 17, what be oppositely arranged with it then is a form anchor 21.This form anchor is remained on its position by the compression spring 22 that is supported on the cover piece 12.Form anchor 21 is opposite with other structural members, is made by ferrimagnet.Therefore, form anchor 21 attracts magnetized shop bolt 19, this shop bolt be inserted in as previously mentioned the hole 17 of locking plate 17 ' in.On the embedded location of magnetization shop bolt 19, slide plate 16 can not promote from its home position.People might be arranged on the part of the support slot 18 of slide plate 16 in the rotary body of unshowned slide plate, so that can realize the code-locked conversion by the rotation of this rotary body.

Between form anchor 21 and prerotation vane 20, keeping patchhole 7.The front cross seamed edge 20 of prerotation vane 20 and form anchor 21 ', 21 ' round about the bending, constitute a wedge-shaped slot that is used for inserting key card 8 thus.

The extension spring 23 usefulness one ends of using as back-moving spring are fixed on the horizontal tenon 24 of middleware 11.This horizontal tenon 24 stretches out from middleware and slide plate 16 opposing sides, extend in the inner chamber of end part 10.The other end of extension spring 23 is fixed on the projection 26 of passing middleware 11 slits 25 of slide plate 16.Therefore, slide plate 16 spring 23 that is stretched moves to home position shown in Figure 4.The nose 27,28 of two inclinations of slide plate 16 is along with projection 26 moves together, and these noses 27,28 are with projection 26 equally tight being stuck on the middleware 11.The inclined-plane 27 of nose 27,28 ', 28 ' almost parallel ground constitutes.They clip the oblique crimp 29,30 along the transverse slat 31 of the rigid arm 32 of the lateral adjustments of skateboarding direction, and this rigid arm 32 has an elastic segments 33 in the key card insertion end, and this elastic segments is in the corresponding zone in the lock housing 9.

Extending with the opposed other end of fixed end on the arm 32 a crank-like part 34, connect thereon be a forked end 35, referring to the figure of the rigid arm shown in the chain-dotted line 32 among Fig. 7.This forked end 35 is embedded in the cannelure 36 that meshes on the clutch sleeve 37.The central region of the internal tooth of this clutch sleeve is blocked by a darker circular resection part 38.According to disengaged position shown in Figure 4, the tooth 39 of a pinion 40 extend in the annular section 38 of clutch sleeve 37, and this pinion 40 has the bigger flange of cross-sectional area 41, and is arranged in the support holes 42 of end part 10.A radial slot 43 is arranged in flange 41, in this groove setting-in the T shape end 44 of a push-piece 45.This push-piece 45 connects with inner rotary handle 6 rotations.

A gear 46 is located at the opposite of pinion 40, and the gear teeth of pinion 40 and gear 46 are all identical, and matches with the internal tooth of clutch sleeve 37.This gear 46 connects securely with outside rotary handle 4 on its side.The blind hole that matches 46 on gear 46 cross sections of centering tenon 40 that stretches out by pinion 40 ' in order to the stability of the relative position that increases pinion 40 and gear 46, this centering tenon 40 ' be inlaid in ' in.Equally, gear 46 also extends in the inside of cover 15, and the flange 46 that cross-sectional area is bigger " is installed in the support cavity 47 of cover 15.On disengaged position, clutch sleeve 37 only is enclosed within on the pinion 40, therefore, is not in engagement with gear 46.The swing offset of outside rotary handle 4 can driven gear 46 and push-piece 45 be synchronized with the movement.

The end face edge of clutch sleeve 37 is stretched out a positioning convex 48 that bends towards push-piece 45, and this positioning convex embeds in the insertion mouth 49 that is set on the lock housing 9, referring to Fig. 4 according to the breech lock end position of corresponding latch fitting.

Slide plate 16 respectively is equipped with a brake cam 50 along the leptoprosopy next door of glide direction.The spring section 51 of two brake cam 50 and arm 32 sides ' stop nose 51 concur.

Can produce locking-typed pin between key card 8 and the slide plate 16 is fixedly connected.This connection is to be realized by the pin in the hole 52 that is located at slide plate 16 53.This hole 52 is positioned near the aperture of key card patchhole 7.Two such holes 52 can be symmetrical in the longitudinal midline setting of slide plate 16.Preferably only be equipped with a hole 52 that has pin 53.The two ends 54,55 of pin 53 are tapered.The total length of pin 53 than the thickness of slide plate 16 more greatly., when being in the backhaul final position, slide plate 16 is embedded in the blunt cone tank 56 on lock housing 9 or the middleware 11, form fit towards the tapering point 55 of middleware 11.The height of the depth ratio tapering point 55 of this groove 56 is littler.On the backhaul final position, another tapering point 54 is also gone up outstanding from another wide of slide plate 16, and stretches in the key card patchhole 7 by following form, and promptly tapering point 54 passes the axial clearance 57 of locking plate 17 and prerotation vane 20, is against on the form anchor 21.

One of two holes 58 on this pin 53 and the key card 8 acting in conjunction.These two holes 58 are symmetrical in the longitudinal midline setting of key card 8 equally.When arranging two holes 52 and two holes 58, the prerotation vane 20 that has two axial clearances 57 is to be provided with like this, and promptly along with the packing into of each pin 53, pin extends through one or another axial clearance.Yet this lock also can make like this, and a hole 58 is promptly only arranged on the key card 8, and a hole 52 is also only arranged on the slide plate 16.The same change also done in axial clearance 57 on prerotation vane 20.Pin 53 can also be arranged on other positions of slide plate 16.A kind of modification that it is contemplated that is, this pin 53 has the diameter identical with system bolt 19, and therefore, it can be installed on the slide plate 16 in the corresponding support holes 18.

The working method of aforementioned lock is as follows:

If an outside handgrip 4 of lock 1 usefulness is opened from the outside, so just need to have the key card 8 of respective coding to insert in the key card patchhole 7.Thus, lateral displacement takes place in the form anchor 21 that is loaded by compression spring 22.On the position that key card inserts fully, the insertion end leading edge 8 of key card 8 ' arrive to point to the slide plate block 16 of cover piece 12 directions ' on.In this position, this magnetization system bolt 19 is subjected to displacement, promptly they leave the hole 17 of locking plate 17 ', in addition, aimed among two holes 58 of key card 8 towards the end 54 of the pin 53 of key card patchhole 7.At this moment can continue to promote key card 8, thus, the pulling force that overcomes extension spring 23 drives slide plate 16.When slide plate 16 moved, the groove 56 that connects with tapering point 55 was to control pin 53 like this, as shown in Figure 5, pin was embedded in the hole 58 of key card 8.Though a kind of do not have the key card in hole can insert yet, slide plate 16 can not move forward, because pin 53 is not deviate from the leeway of doing of groove 56.

The reach position on, spring section 51 ' stop nose 51 be against subsequently on the brake cam 50 of slide plate 16, and make slide plate 16 remain on the reach position on, referring to Fig. 5.Be accompanied by moving of slide plate, load to transverse slat 31 by nose 27, arm 32 is around its stretch section 33 swings.Because the forked end freely 35 of this arm 32 is in engagement with clutch sleeve 37, so this sleeve also is struck, and enters engagement with gear 46.At this moment, not only pinion 40, and gear wheel 46 all is in engagement with the internal tooth of clutch sleeve 37, thereby the action of outside rotary handle 4 can cause pinion 40 and push-piece 45 synchronization actions that are connected with pinion.Be accompanied by operator 4 swing offset, block tongue 5 breaks away from a locking plate on the doorframe limit.Have only the positioning convex 48 of clutch sleeve to break away from insertion mouth 49 on the lock housing 9, the action of this outside rotary handle 4 is only possible.

For key card 8 can be pulled out, must be by means of operator 4 with latch fitting, for example clutch sleeve, push-piece and block tongue drive their locking end position.Then, the positioning convex spare 48 of clutch sleeve 37 is aimed at the insertion mouth 49 on the lock housing 9.When key card 8 was extracted out, slide plate 16 was moved on the final position of backhaul forcibly by the pin 53 that inserts in the key card.Pin 53 has arrived on the position of aiming at groove 56 simultaneously, therefore key card is all extracted out.In the process that key card extract out to move, brake cam 50 and spring-latch 51 ' stop nose 51 between stopping function be releasing like this, promptly set back again.The flanging 30 of 28 pairs of transverse slats 31 of another nose of slide plate 16 loads, and arm 32 is back on its terminal location, and like this, clutch sleeve 37 also moves and returns.

If latch fitting does not turn back on its terminal location, but clutch sleeve 37 still is retained on the rotation centre position push-piece 45, is exactly the sort of situation shown in Figure 6 so.Slide plate 16 can begin within the specific limits to move by means of key card 8, if but positioning convex spare 48 is supported on the seamed edge of support holes 42 sidewalls, and this moving just has been limited.Nose 28 loads downwards by 30 pairs of rigid arm 32 of flanging, and this rigid arm 32 can not continue to move down owing to the support of positioning convex spare 48, has therefore constituted a locking device that stops slide plate 16 travelling backwards.In addition, key card 8 is blocked and can not be extracted voluntarily by locking-typed pin 53 under the locking device effect.This just reminds the user to note, must be with operator reversing to the position latching of regulation.

Can see a kind of insertion locking device from the front is described, this is to realize with corresponding engagement of gear 40,46 by clutch sleeve.If before key card inserted, this engagement did not have harmonious, this clutch sleeve 37 just can not move so.

Fig. 8 to 11 expression the present invention locks 1 ' second embodiment, it is a similar locking device of structure, identical structural member has identical Ref. No..It and the first embodiment difference only are arm 32 ' be used as spring-latchs, and this spring-latch and forked end 35 thereof are in engagement with clutch sleeve 37.In addition, locking device is made of the prolongation 59 of slide plate 16, and specifically, this prolongation 59 is arc.In the vault zone of arcuate apertures 60 a key projection 61 is arranged, this key projection, is embedded in the groove 62 on latch fitting (clutch sleeve 37) sidewall when being in the normal position at latch fitting (clutch sleeve 37).

Shown in Fig. 8 and 9, slide plate 16 moves forward from its home position, and this is identical with previous embodiment.This reach position is provided by Figure 10 and 11.On this position, 4 with corresponding latch fitting (clutch sleeve 37) rotation, make the key projection 61 on its groove 62 misalignment prolongations with operator, slide plate 16 just can not return on its home position fully so, on the contrary, slide plate is in a kind of lock-out state.The situation of this moment is that key projection 61 is supported on the jacket wall of clutch sleeve 37, and does not allow slide plate 16 to continue displacement.Because pin 53 also enters the lock-out state that is connected with key card 8, so this key card 8 can not be extracted from key card patchhole 7.Furthermore, on this position, people need be operator the 4 groove 62 mutual positions of aiming at that are torqued into key projection 61 and latch fitting (clutch sleeve 37), after this, slide plate 16 just can return on its home position fully, and this key card 8 also can be extracted from key card patchhole 7 thereupon.

Can realize inserting locking with following method, promptly on the prolongation 59 of slide plate one second key projection 63 is set, referring to the chain-dotted line among Fig. 9.The second key projection is positioned at the opposite of the first key projection 61, and with latch fitting or claim another groove 64 actings in conjunction on the clutch sleeve 37.If second key projection 63 and another groove 64 are not in engagement, can only make slide plate 16 do non-omnidistance reach with the key card of stipulating, thereby realize inserting locking.

" shown in Figure 12 to 14, wherein identical structural member uses identical Ref. No. to the lock 1 of the 3rd embodiment.Different with previous embodiment is, this lock structure is made of a lever 65 adjacent with slide plate 16.This is an angle square shape lever that is located at the lock outside, and lever can be swung on cover piece 12 flexibly around pin 66.Angle arm 65 ' constitute a key projection 67, groove 68 actings in conjunction on 67 and dish type latch fittings 69 of this key projection in the end.This latch fitting 69 is fixedlyed connected with gear 46, and it also firmly connects 4 with operator thus.This lever 65 is preferably loaded along clockwise direction by a spring that does not illustrate.Under key projection 67 is embedded in the groove 68 of latch fitting 69 time, auxiliary fixing member 71 and another angle arm 65 with oblique top " limit groove 70 aim at.The side of this auxiliary fixing member 71 is connected on the spring-loaded bar 75.This bar 75 is horn shape, and is hinged on swingably on the slide plate pin 72.A compression spring 73 loads bar 75 along the direction of lever 65.

If key card 8 is inserted in the key card patchhole 7, will be in the position shown in Figure 12 and 13.This auxiliary fixing member 71 puts in the limit groove 70, but does not stretch in the hole 74 of key card.People can cause position shown in Figure 14 by key card 8.In this reach process, auxiliary fixing member 71 is because the effect of respective ramp, move to lever 65 below, simultaneously, on this auxiliary fixing member 71 with the opposed hole 74 that is partially submerged into key card 8 of above-mentioned chamfered portion in, referring to Figure 14.Be accompanied by the reach of slide plate 16, unshowned clutch sleeve also is pushed, and produces to connect between the operator of pin 45 and outer side of door is 4.If this moment, push-piece 45 and latch fitting 69 were brought to the position of rotation that a groove 68 does not have alignment keys projection 67, lever 65 just is moved on the position that solid line is represented in the chain-dotted line and Figure 14 among Figure 12 so.Slide plate 16 can turn back to its home position from above-mentioned position by key card 8, but owing to mobile this key card 8 that makes of lever 65 can not be extracted out.Auxiliary fixing member 71 stretches in the hole 74 of key card 8, and with lever 65 fixture 71 is remained on this position.Have only when latch fitting 69 is operated handgrip 4 and brings the spin angular position of regulation into, aim at the key projection 67 of lever 65, just might extract key card 8 out at this position upper groove 68.Then, auxiliary fixing member 71 is positioned at the opposite of the limit groove 70 of lever 65, and this auxiliary fixing member 71 can embed in this limit groove 70.In the present embodiment, can cancel independent pin 53, because auxiliary fixing member 71 will work the effect of being connected and fixed.

The 4th embodiment described in Figure 15 and 16 is similar with the 3rd embodiment to a great extent.Difference is the spring-loaded situation of bar 75, and promptly the spring-loaded direction of present embodiment is consistent with the direction of key card patchhole 7." projection 77 to bar 75 loads for this purpose, to be provided with a torsionspring 76 on slide plate pin 72, an end 76 of this torsionspring ' be fixed on the slide plate pin 72, and the other end 76.According to the method, if latch fitting is not in the position of regulation, the effect of this auxiliary fixing member 71 is not only as one and is pushed stopper, and is as extracting stopper out.

Figure 15 express the lock 1 ' " the home position.People can push key card 8 in the key card patchhole 7.But,, just key card 8 can not be pushed if lever 65 does not swing to the assigned position of latch fitting.This be because, limit groove 70 is not aimed at auxiliary fixing member 71, when key card 8 pushes, the skew space that auxiliary fixing member 71 there is no need.If latch fitting 69 is in the position of regulation, this position is digital projection 67 and the groove 68 mutual positions of aiming at, and so not only key card 8 can push, and slide plate 16 also can move forward by key card 8.On this reach position and under manipulating handgrip 4 and situation that push-piece 45 connects, the operation of can locking a door accordingly.If latch fitting 69 remains on the centre position after this, this slide plate 16 can move to its home position equally, but key card 8 can not extract because auxiliary fixing member 71 can not be embedded in the limit groove 70 of lever 65.Therefore, the user has obtained how causing the prompting of the position latching stipulated, and on position latching, key projection 67 is embedded in the groove 68 of latch fitting 69.After this, the limit groove 70 of lever 65 is aimed at auxiliary fixing member 71, and at this moment key card 8 can be extracted, and simultaneously, needs only key card 8 to auxiliary fixing member 71 reinforcings, and this auxiliary fixing member just moves in the limit groove 70, returns the home position subsequently again, as shown in figure 15.
