Description

Insert cipher key that some position is magnetized and remove the lock of locking effect
The present invention relates to a kind of its locking effect can be by inserting the lock that the magnetized cipher key in some position is removed, in this lock, the end limit of cipher key promotes the slide plate after a magnetic bolt restraining pin discharges, the position of slide plate after reach is braked, and makes check mechanism be in the off-position after the local travelling backwards of cipher key.
The lock of the above-mentioned type is known by EP0241323A2, and two elastic parts are wherein arranged, and is used to brake to overcome slide plate after the spring force reach by means of cipher key, and their withstand on the hinged catch pawl from behind with the crimp that is in the slide plate side.The wide area that faces slide plate on the cipher key during by the insertion cipher key is handled catch pawl.Catch pawl enters carriage when extracting cipher key, and the backspring that at this moment is connected on the slide plate works, and catch pawl is thrown off with flexible crimp contact.The possible maloperation of this lock; Cipher key can be extracted, but owing to for example block or inserted paper slip etc., makes the position after slide plate rests on reach.Its consequence is to make clutch be in engagement all the time, so anyone can open door.
The objective of the invention is to provide a kind of more lock of the above-mentioned type of high-reliability that has, this being locked in after cipher key extracts, slide plate is in the original position after its travelling backwards all the time.
Above-mentioned purpose reaches by feature of the present invention, promptly between cipher key and slide plate, constitute a kind of just slide plate arrive the travelling backwards final position not long ago just self-detaching be rigidly connected, be rigidly connected is to be contained in the slide plate and the pin that moves in the hole that enters cipher key automatically by slide plate constitutes by one, the pin two ends are designed to taper, pin is contained near the arrival end of cipher key patchhole, controls arrangement of clutch between control handle and the depression bar by moving of slide plate and divides or close.
Provided the higher such lock of a kind of reliability according to this design.It can guarantee that all the time after extracting cipher key, slide plate is in its travelling backwards final position.Can not change the locking mode that meets the requirements.Have only with cipher key up to specification and just can make the correct work of lock.The cipher key that conforms with the regulations is distinguished because of moulding is slightly different to some extent with general cipher key, it wherein at first is the connection that rigidity can be arranged between cipher key and slide plate, layout on cipher key has important change equally, and this is to have obtained the effect of a kind of system bolt with regard to certain viewpoint.In addition, slide plate has also been done modification at corresponding site, is rigidly connected so constituted between these two corresponding positions on slide plate and the cipher key.Be rigidly connected and insert fully or cipher key is just finished when beginning to move forward slide plate at cipher key.A kind of its characteristics of advantageous remodeling are, be rigidly connected by one be contained in the slide plate pass through that slide plate moves and the pin that enters automatically in the cipher key hole constitutes.Therefore obtaining the required fabricating cost of this additional function can be very low.The suitable pin of only need in slide plate, packing into.Certainly must be shaped on the hole in the relevant position of cipher key.This means that when locking inserting in the hole of cipher key when inserting cipher key, pin and hole should be aligned with each other.In the reach process that begins then, the pin that matches with the hole enters in this hole, and stays in this hole during the position after slide plate is in reach.When extracting cipher key, will inevitably drive slide plate by pin.Have only the action of pulling out cipher key outside to the end during the stage, pin just leaves this hole.Because taper is made at the two ends of pin, thereby it is mobile to help the pin turnover.In addition, the length of pin is greater than the thickness of slide plate, so on the extended slide plate in its termination.During position after slide plate is in travelling backwards, its a truncated cone shape end inserts on the lock box one preferably in the hole of truncated cone shape.After inserting cipher key and beginning reach, the hole of truncated cone shape is left in a truncated cone shape termination of pin, its another be in relative position the truncated cone shape termination then insert in the hole of cipher key.If selected cipher key does not have the hole in the place of regulation, although then cipher key can be inserted, because pin can not be offset, thereby slide plate can not move forward.Pin can prevent that as interlock limited slip plate moves forward under the situation without permission.It is only facing to the position of cipher key patchhole inlet region pin being installed on slide plate.Under the possible mode of occupation of a kind of the best of this lock, the effect of slide plate is when it moves, between control handle and the depression bar arrangement of clutch deciliter.When extracting cipher key, should guarantee to throw off the connection between control handle and the depression bar.Here related control handle refers to the operating mechanism at outer side of door, can not arbitrarily handle so have by the designed mortise lock that is contained on the door of the present invention.

Fig. 1 is the lock 1 by the present invention's design, and it is contained on the door 2, for example the door in hotel.Lock 1 has its flat shape of the outside that is contained in door to be designed to the spring lock 3 of rectangle, is adorning control handle 4 at that end at spring lock place.Can make bolt 5 withdrawals with handle 4.The interior rotating handles 6 that is contained in door 2 inboards directly is connected with bolt 5, so always can open door in the inboard of door 2.
That end relative with handle 4 is provided with the socket 7 of inserting cipher key 8 on the spring lock 3, and the position that has on the cipher key 8 is through magnetized.Lock box 9 is housed in spring lock 3.Lock box 9 has 10, one middle parts 11, a bottom and a loam cake 12.The screw 13 that half bowl-type bottom, 10 usefulness enter middle part 11 is connected with middle part 11.Should earlier above-mentioned these two parts 10 and 11 be fitted together, at this moment, on the middle part 11 towards bottom 11 outstanding locating pieces 14 to insert on the bottom 10 be their set grooves 15.Screw 13 also is used for fixing loam cake 12 simultaneously.The lock box sidewall 16,17 that extends along the cipher key direction of insertion is arranged on the lid 12, and the key insertion end is provided with inside support ledge 18 on sidewall, and screw 13 is contained in the support ledge.Loam cake 12 and socket 7 those relative ends have a tongue piece 19, and when promoting loam cake 12 on middle part 11, tongue piece inserts in the groove 20 of middle part 11 boss 21.In addition, that end relative with tongue piece 19 implemented rear portion and connected on sidewall 16,17, and for this reason, the hook-type of middle part 11 and loam cake 12 projection 22 or 23 is overlap joint each other.
Then, bottom 10 and middle part 11 are combined into an assembly with two other screw 24 with them again at that end that deviates from socket 7.Bottom 10 and middle part 11 are alumiaum article, and loam cake 12 adopts plastics.A tabular slide plate 25 that is made of plastics is equally arranged between loam cake 12 and middle part 11.Slide plate 25 is contained on the middle part 11 with its wide one side.A jam plate 26 of being made by brass has constituted a spigot surface 26 that is in relative position, and jam plate is contained in the loam cake 12, and can not fix retroactively by side direction projection 27,28 there.Under the position that the represented lock of Figure 11 is lockable, the pin installing hole 30 of making through hole on the hole 29 on the jam plate 26 and the slide plate 25 aligns.Magnetic bolt restraining pin 31 is housed in the installing hole 30.The quantity of bolt restraining pin 31, position and polarity there is no need bolt restraining pin 31 all is installed in each pinhole 30, because will decide by the unlatching password combination of lock 1.
Opposite side at jam plate 26 has one to be similarly brazen guide strip 32, and guide strip 32 opposite sides relative with jam plate 26 have anchor slab 33.Three compression springs 34 of anchor slab 33 usefulness are fixed on its position.Above-mentioned compression spring 34 is bearing on the loam cake 12.
Different with other part, anchor slab 33 is made by ferrimagnet.Therefore, anchor slab 33 can attract the bolt restraining pin 31 of magnetic, and they are inserted in the hole 29 of jam plate 26.Under this position,,, make it and to move from its represented home position among Figure 11 so stop slide plate 25 because bolt restraining pin 31 inserts in the fixed jam plate 26.Establish the pinhole of a part of slide plate 25 in the rotary body of the slide plate 25 that can also not represent in the drawings, so that can change coding by rotating this rotary body.
Anchor slab 33 and guide strip 32 adjoin with the socket 7 of spring lock 3.Their anterior horizontal edge 32 ', 33 ' with opposite direction deflection, and constitute a wedge that inserts cipher key 8.At this moment, the wide surface that guide strip 32 and anchor slab 33 are opposite each other has formed cipher key patchhole 35.
Tension spring 36 as backspring is fixed on the horizontal pin 37 at middle part 11 with the one end.This horizontal pin 37 11 is in that side of relative position with slide plate 25 from the middle part, stretches into the inner chamber of bottom 10.The other end of tension spring 36 is fixed on the slide plate 25 on the projection 39 of passing from the groove 38 at middle part 11, so moves in the slide plate home position that can limit in Figure 11.In addition, before projection 39, slide plate 25 stretches out two oblique noses 40,41, and they also pass middle part 11 as projection 39.Inclined-plane 40 on the nose 40,41 ', 41 ' parallel to each other.They abut on the crimp 42,43 that the partition 44 of the reed 45 that elastomeric material makes tilts.The central gap 46 that this moment, nose 40 passed reed 45.
At the reed 45 of key insertion end, between middle part 11 and bottom 10, extend, and it is fixing to be passed the screw 13 of reed 45 through holes 47 there.
That end 48 relative with reed 45 fixed ends is designed to forked, and is inserted with in the cannelure 49 of clutch sleeve 50 of internal tooth.In throw-out-of clutch position shown in Figure 11, clutch sleeve 50 and pinion 51 engagements, pinion 51 is contained in the installing hole 53 of bottom 10 by a bigger flange 52 of cross section.Have one along diametric otch 54 on flange 52, the head 55 of "T"-shaped depression bar 56 is inserted in this otch."T"-shaped bar is connected with interior rotating handles 6 torsion passes.
What be in the relative position place with pinion 51 is gear 57.Pinion 51 is identical with the profile of tooth of gear 57, and the internal tooth of they and clutch sleeve 50 matches.Gear 57 is fixedlyed connected with inner rotary handle 4.From the centering axle journal 51 of pinion 51s ' be used for making gear 51,57 positioning stablities, the blind hole 57 that a size of axle journal 51 ' be inserted in gear 57 matches with it ' in.Gear 57 extends in the boss 21 at middle part 11, and " is contained in the support holes 58 of boss 21 by a flange 57 that cross section is bigger.In the throw-out-of clutch position, 50 of clutch sleeves and pinion 51 engagements, and with gear 57 engagements.Pinion 51 can not be driven when therefore rotating inner rotary handle 4, thereby also depression bar 56 can be do not driven.For making clutch sleeve 50 can arbitrarily not leave its home position, a compression spring D round clutch sleeve 50 is set, its end is pressed in boss 21 inboards, the other end be pressed in the flange 50 of clutch sleeve 50 ' on.
Slide plate 25 respectively is equipped with a block 59 on the narrow limit of glide direction.The side spring leaf 60 common cooperatings of they and reed 45, these two spring leafs 60 by braking shoulder 60 ' with block 59 co-operation.
Can set up a kind of being rigidly connected between cipher key 8 and slide plate 25, it is made of the pin 62 in the hole 61 that is contained in slide plate 25.Hole 61 is in the entrance of cipher key patchhole.Be provided with two holes 61 according to this embodiment to slide plate 25 longitudinal centre line symmetries.Yet have only in the hole 61 and be equipped with pin 62.Taper is made at the two ends 63,64 of pin 62.The total length of pin 62 is bigger than the thickness of slide plate 25.Tapering point 64 towards middle part 11 inserts in the frustum-like shape hole 65 at lock box or middle part 11 under the travelling backwards final position of slide plate 25.The degree of depth in hole 65 is less than the height of tapering point 64.Under this travelling backwards final position, another tapering point 63 is given prominence on another wide surface of slide plate 25, and inserts in the cipher key patchhole 35, thereby the slotted hole 66 that makes tapering point 63 pass guide strip 32 leans on anchor slab 33.
The common cooperating in one of two holes 67 of pin 62 and cipher key 8.Hole 67 is symmetrical in the longitudinal centre line setting of cipher key 8 equally.When two holes 61 and two holes 67 are set, also should be equipped with two slotted holes 66 so on the guide strip 32, and according to the installation situation of pin 62, pin will pass this or that slotted hole.But also lock can be designed to have only a hole on its cipher key 8, on slide plate 25, also have only a hole 61.Slotted hole 66 on the guide strip 32 also is like this.Also can also pin 62 be set in other positions of slide plate 25.Can consider to be modified as and make pin have the diameter identical, thereby pin also can be packed on the slide plate 25 in the corresponding installing hole 30 with bolt restraining pin 31.
The working method of this device is as follows.If want and to use inner rotary handle 4 operated locks 1 outdoors, then need there being the cipher key 8 that conforms with the regulations to insert socket 7.Cipher key 8 is along the anchor slab of laterally pushing open under the spring 34 pressure effects 33.Under the position of inserting fully, the insertion end edge 8 of cipher key 8 ' be parked on the slide plate 25 towards the slide plate stop block 25 of loam cake 12 projections ' preceding.Under this position, magnetic bolt restraining pin 31 moves to the hole of leaving on the jam plate 26 29.In addition, pin 62 one of is aimed on the cipher keys in two holes 67 towards an end 63 of cipher key patchhole.At this moment can be moved further cipher key 8, overcome the power of tension spring 36, promote slide plate 25.In moving process, under hole 65 and tapering point 64 actings in conjunction, pin 62 is moved, thereby insert as shown in figure 13 in the hole 67 relevant on the cipher key 8.Although a cipher key of not establishing the hole also can insert, yet slide plate is moved forward, because reserve the required space of skew for pin 62.
Position after reach, braking shoulder 60 ' from behind blocks 59 that withstand on the slide plate 25 of spring leaf 60 make the position after slide plate 25 remains on reach.In slide plate 25 reaches, the inclined-plane 40 of nose 40 ' power of effect on partition 44 makes reed 45 rotate around its fixed point.Because the fork-shaped openend 48 of reed 45 is inserted on the clutch sleeve 50, so its removable clutch sleeve, and make it also to mesh with gear 57.These two gears 51 and 57 all mesh with clutch sleeve 50 now, therefore just can operated lock 1 with inner rotary handle 4.Under clutch is in connection status, can not extracts cipher key and make lock still keep the clutch connection status.When pulling out cipher key 8 outward, will inevitably make slide plate 25 move on to the travelling backwards final position by the pin 62 that enters in the cipher key 8.The position that this moment, pin 62 arrival were aimed at hole 65, and thereby allow cipher key is extracted fully.Outside cipher key, pull out in the process, overcome the braking action between baffle plate 59 and reed 45 braking shoulders 60, and be in original position again.In like manner, clutch sleeve 50 also thereby reset, another nose 41 makes reed 45 also be moved back into its final position by its inclined-plane 41 ' power of effect on the crimp 43 of partition 44.
In addition, fixed electric switch 68,69,70,71 on lock box 9, they are by slide plate 25 controls.The control of relevant electric switch is not important content of the present invention, so introduce no longer in detail.
The present invention is disclosed feature in above-mentioned explanation, accompanying drawing and claim, no matter is single or any combination, all is to implement the present invention.All features that are disclosed all are essentiality contents of the present invention.In the application's disclosure, comprised disclosed full content in the appended relevant file that enjoys priority (copy of first to file).
