Content of the invention

The task of the present invention is, provides a kind of latch system, and this latch system provides the operation comfort improving.

This task is solved by having the latch system of the feature of independent claims.The favourable design of the present invention and enter one Step composition is given in the dependent claims.

The latch system according to the present invention starting described type is characterised by, the lock piece of lock is configured to dead bolt, with Just moving to lock position from unlocked position, and lockset having electric driver, described electric driver coordinates with lock piece Effect, in order to make described lock piece move to unlocked position from lock position.

Therefore, in the latch system according to the present invention, motion between unlocked position and lock position for the lock piece is led to Cross following manner to realize, i.e. lock piece is constituted as dead bolt, is in lockable position for stop sheet material when phase-locked When, described dead bolt occupies lock position accordingly automatically.

In contrast, lock piece moves through electric driver control between lock position and unlocked position.Therefore, Only needing to unlock for example to handle switch, described switch is by control equipment manipulation driving means, and does not needs to pass through The lock of door handle or machinery carrys out mechanically operated lock stop member.Alternatively, in order to manipulate driving means, it is possible to use motion detection Device or be arranged on touch sensor that is on door leaf or that be integrated in door handle, thus even without carrying out special switch behaviour Vertical.Equally, the manipulation of lock piece can be carried the key with user by wirelessly work or be passed through it together The connection that he is wireless such as bluetooth, WLAN (Wireless Local Area Network), RFID (Radio Frequency Identification) carry out with analog, if desired the suitable application on combined with intelligent mobile phone or the like (“App”).

By the automatic locking such as in the case of dead bolt and can the combination of unblock of electricity manipulation, the locking of conventional mechanical lock The function of part and dead bolt is concentrated in a unique construction element, and described construction element is referred to herein as " lock piece ".

The present invention be not only suitable for for building door and also be suitable for preventing cabinet or other furniture or storage door or Lid be not intended to open.

In a kind of favourable form of implementation, operated lock stop member unlocks and only carries out in electrically driven (operated) mode.This allows lock Very simple and construct little design.Then it is only the problem of the programming of control device, i.e. door is can be opened by handling Close and open or by lasting locking, and unblock is only handling switch by special key or by inputting electronics secret key When can realize.But the door handle including operating mechanism can be additionally provided with, described operating mechanism fills independent of driving Put and be applied on lock piece.Door handle for example may be used for emergency release.

Lock power supply can carry out alternately through battery or induction type coupler, described coupler by electric energy from doorframe Side is transferred on door leaf, thus when lock is in movable door leaf together with electric driver, it is not necessary to sliding contact or soft Property cable is powered.

Because not needing the handle for mechanically operated lock stop member, thus also permissible in the system according to the present invention It is lock to be arranged on border side and be arranged on stop sheet material on door leaf side, supply from without to the door leaf of motion Electricity.In order to handle, switch can be positioned in frame region or on wall equally.Alternatively it is possible that, solution will be used for and lock a door Switch, such as capacitive touch sensor is arranged on door leaf and causes unblock.The signal of this touch sensor is for example permissible By capacitive coupled transfer to border side.Switch is equally set on door leaf, described switch by radio and/or Optically, for example by photoelectrical coupler and the control electronic installation communication on border side.

In a kind of favourable design of latch system, described lockset has the electromagnet with coil to fill as electric drive Putting, the axis of described coil is parallel to the direction of motion orientation of lock piece, and described coil and armature mating reaction, this armature It is connected with lock piece rigidly.Such driving means mechanically simple designs and therefore corresponding low cost and maintenance are few.

Alternatively, lock piece can be by flexibly pre-tensioner in unlocked position, thus door unlocks when coil no current And it only is maintained in lock position when coil electricity.When having a power failure, door automatic unlocking.This design is for example suitable for washing one's hands Between door, described restroom door generally has only to be tentatively held in closed position.For activating and deactivating the switch of electromagnet Have only to be arranged on the inner side of door.

In other form of implementation, lock piece is maintained in lock position and can be with self-insurance with being possible not only to self-sustaining It is maintained in unlocked position with holding, and have only to convert coil electricity the position of lock piece.Under normal circumstances, it is used for The switch of locking and unblock is arranged on the two sides of door.But it can be possible that by door simply by following manner in one side Upper " locking ", i.e. additional switch is set in the one side of door, utilize described additional switch can electronically forbid from The unblock of opposition side.This design is for example adapted in the door in house and can be formed in living space, thus described Door cannot be opened from corridor side.On the other hand may be constructed such that circuit so that when door is opened from living space side, described Forbid automatically cancelling.It is possible to prevent user from by mistake locking out oneself.

Described lock piece can be similar to the dead bolt of routine and be provided with collision inclined-plane, thus described door can mechanically be locked On.But in a kind of particularly advantageous form of implementation, the control device for described driving means has sensor, described biography The closed position of sensor detection door and/or the arrival of closed position.Once described sensor determines that door is opened, then lock piece is protected Holding in unlocked position, and once sensor determining that door arrives again at closed position, lock piece is automatically transitioned to locking position In putting.Provide the dead bolt of a kind of active by driving means.This has the advantage that, i.e. can make described door actually It is voicelessly locked, this is because avoid the common impact noise when dead bolt strikes on stop sheet material.The closedown of door Motion is only passed through when reaching closed position generally to buffer at sealing device present on doorframe, thus door very low noise ground closes Close.Described solution especially can be also suitably used for swing door, and described swing door is locked in the position of closedown, but at locking For example can open along both direction after being cancelled by motion detector or contact witch.

In the favourable form of implementation of another kind, use magnetic padlock tongue principle, in order to make lock piece in the correct position of lock Move to lock position from unlocked position relative to stop sheet material.For this for example can on stop sheet material side and/or lock side On permanent magnet is set, described permanent magnet by lock piece passively magnetically towards lock position direction attract.

In the favourable design of the another kind of latch system, described lockset has the motor as electric driver, wherein, electricity The rotary motion of machine is preferably delivered on lock piece by tooth bar.

Here it is preferred, in particular, that motor is applied on slide block, described motor is preferably parallel to lock piece and draws movably Lead, and described motor couples with lock piece.Here further preferably slide block and lock piece are so coupled to each other so that Described slide block and lock piece have gap along their channeling direction each other, so that lock piece is not in the primary importance of slide block Be only capable of in being in the unlocked position and be in lock position, and so that in the second place of slide block locking During part is in the unlocked position.It is capable of by freedom of motion space in the primary importance of slide block for the lock piece：Lock piece can To move in lock position from unlocked position and therefore, it is possible to realize lock piece as the function of dead bolt.

It in the one of latch system is constituted further, is provided with the 3rd position of slide block, in described 3rd position, locking Part is in lock position.In the 3rd position, lock piece moves in lock position actively by electric driver.Work as lock When stop member tilts with the pattern of dead bolt, described press-in causes the active of door to be closed, and door leaf is pressed into door seal device when closed In.Such closing process for example may be adapted to stop the process in the gap between doorframe and door, or is suitable to special sound insulation ground Close door.If the 3rd position of slide block is kept enduringly by driving means, then obtain the higher closedown peace of latch system Quan Xing.The lasting holding of the 3rd position for example can be realized by the driving means of self-locking with noenergy.

Detailed description of the invention

The doorframe 10 of door (being to rotate door in this example) and the section of door leaf 12, institute are shown in FIG in the cross-section State doorframe and door leaf to be mutually locked by the system according to the present invention.Stop sheet material 14 is put into as usual in doorframe 10, Described stop sheet material has breach 16, and in the present embodiment, the inserts 18 with cavity shape recess embeds in described breach.At door The inner containment of page 12 has lock 20, and described lockset has lock housing body 22 and by also referred to as on the side towards stop sheet material 14 The closing sheet material 24 of astragal is closed.

It is to be noted that in this embodiment illustrating in this application and other embodiments, lock 20 also can be arranged on In doorframe 10 and stop sheet material 14 also can be arranged in door leaf 12.

Lock piece 26 is directed in lock housing body 22 movingly and is illustrated in lock position in FIG, in institute Stating in lock position, described lock piece is stretched in the recess of inserts 18 and therefore by door leaf 12 by the opening of closing sheet material 24 Shape is locked in opening 16 in locking manner.Guide for lock piece 26 is formed by bobbin 28, and described bobbin is fixed Be maintained in lock housing body 22 and coil 30 is wound on described bobbin.Coil 30 forms electromagnet, and described electromagnet exists Being locked out in the area of space that part 26 occupies generation magnetic field, described magnetic field is parallel to the direction of motion orientation of lock piece 26.Coil 30 and bobbin 28 in axial direction see can substantially have rectangular shape, the size of described rectangle vertically be more than edge It laterally (is perpendicular to the drawing plane of Fig. 1), thus described coil can be placed in the lock housing body 22 of opposite, narrow.

Lock piece 26 is integrally formed with armature 26a, and described armature is made up of nonmagnetic substance and in described armature Be provided with the permanent magnet of two reverse polarizations with being spaced apart distance the 32nd, 34 (described permanent magnet includes in the example illustrating respectively Two parts).

In the example illustrating, inserts 18 is fastened with permanent magnet 36, and on the contrary end of lock piece 26 It is assemblied in another permanent magnet 38 in lock housing body 22.

Lock piece 26 and the arrangement being made up of multiple permanent magnets exemplify with bigger ratio in figs 2 and 3.Fig. 2 exists This corresponds to lock position, and described lock position also figure 1 illustrates, and Fig. 3 illustrates lock piece 26 in its unlocked position.

32nd, the 34th, north magnetic pole and the south magnetic pole of 36 and 38 are characterized permanent magnet in the accompanying drawings respectively by contrary hacures.

Under state shown in figure 2, lock piece 26 abuts on the permanent magnet 36 in inserts 18, and permanent magnet 32 quilt Permanent magnet 36 attracts, thus lock piece self-sustaining be maintained in lock position.In this position, permanent magnet 32 is somewhat in line Outside the left part of circle 30, and permanent magnet 34 is exactly on the right part of coil.When coil 30 is energized to the right When the attraction that (along unlocking direction) points to is applied on permanent magnet 32, then another permanent magnet 34 of lock piece is open, also I.e. equally along unlocking direction extruding.The power so producing overcomes the attraction between permanent magnet 36 and 32, and lock piece moves to In the unlocked position that figure 3 illustrates, in described unlocked position, described lock piece abuts on permanent magnet 38.In this position In, outside the permanent magnet 32 on the left side is on the left part of coil, and the permanent magnet 34 on the right is in coil and by permanent magnetism Body 38 attracts, thus the present self-sustaining of lock piece be maintained in unlocked position, even if coil 30 again switches to no current also So.Only when coil 30 is energized in opposite direction, lock piece 26 just returns according in the lock position of Fig. 2.

Because the electric current in coil 30 have only to conversion short instantaneous time during flow through, so for power supply for one Individual battery just can meet, and described battery can be placed in lock housing body 22.

Alternatively it can be possible that lock piece 26 is pre-tensioner to the unblock according to Fig. 3 by unshowned spring ground In position.This spring can so design so that even if lock piece 26 is at which in the lock position according to Fig. 2 and stand forever It is still reliably drawn in unlocked position, if coil 30 no current during the attraction of magnet 36.This ensure that and work as Battery for power supply is exhausted or is to unlock simultaneously based on other disturbance interrupted all the time by door during the electric current of coil 30 And can open.But in this case it is required that as long as lock piece 26 should be maintained at according in the lock position of Fig. 2, Just coil 30 is energized constantly.But can so coordinate at this magnetive attraction and spring force so that very little electric current just foot Enough.This solution is especially for as being suitable for Xiamen, and described door is only necessary on the relatively short time period all the time Remain turned-off, for example, be suitable for restroom door.

In other forms of implementation, the electric current for coil 30 also can be provided by power elements and for example by sensing Formula coupler is supplied to door leaf from frame side.

As shown in Figure 1 such, lock housing body 22 comprises circuit board 40, and described circuit board is equipped with use not shown further Electronic component in manipulation coil 30.This circuit board electrically connects with contact witch 42 in the example illustrating, described touch Switch is at least on the outer surface of door leaf 12 on the side of door.In normal state, door is closed and by being maintained at Lock piece 26 locking in lock position is in a closed position.When user wants to open, then this user is pressed into tactile with hand Touching on formula switch 42, thus coil 30 is temporarily activated and lock piece 26 moves in unlocked position.Therefore, user has only to Slight pressure is applied on door leaf 12 or contact witch 42, open door.

When door leaf 12 is again close to closed position, the sensor 44 being arranged on circuit board 40 detects another permanent magnetism The magnetic field of body 46, another permanent magnet described is put in stop sheet material 14 on corresponding position.Thus (generally currentless) Acceleration transducer 48 is activated, and described acceleration transducer detection door leaf keeps off the exact time leaning on folding part.By adding Velocity sensor 48, the again of short duration energising of trigger winding 30, thus lock piece 26 again returns in lock position.Close sheet material 24 are preferably made up of nonmagnetic substance, such as stainless steel, in order to do not shield the magnetic field of permanent magnet 46.

In the example illustrating, lock housing body 22 comprises the quadrangle part receiving portion of the quadrangle part for common door handle 50.But door handle is only used as the handle for making door leaf 12 move in this example but is not used in operated lock stop member 26.With this Correspondence, quadrangle part receiving portion 50 is non-rotatable and rigid, thus door handle can not be pressed down.It is alternatively possible to replace setting Putting the contact witch 42 on the surface of door leaf and also using following contact witch, described contact witch is integrated into the one of door In a door handle on side or both sides or two door handles or described contact witch detection door handle condenser type buffering. In this case, the unblock of door can be realized by touching door handle in a reliable fashion, simply this door handle do not need by Under press.

In order to illustrate this form of implementation, Fig. 1 illustrates metal forming the 52nd, such as Copper Foil, and described metal forming is electrically connected with circuit board 40 Connect and quadrangle part receiving portion 50 is at least surrounded in a part for its periphery.As more clearly figure 4 illustrates that Sample, metal forming 52 has the coating 54 of electric insulation on the side of quadrangle part receiving portion 50.For be made of metal Door handle, here can be seen that quadrangle part 56, and described quadrangle part and metal forming 52 are together with as dielectric coating 54 shape Become capacitor.When user touches door handle, the electric capacity of capacitor changes, and this change is by the electricity on circuit board 40 Road detects and the activation of trigger winding 30.

Alternatively, however, door handle also generally can rotatably be supported by and be the additional machine for lock piece 26 A part for tool operating mechanism.Quadrangle part receiving portion for door handle is then contained in rotatable connecing in known manner In Tou, described joint is mechanically coupled with lock piece 26 as follows by lever and suitable coupling device so that lock piece Also can be converted in unlocked position by door handle alternatively, wherein, electromagnetically-operated and mechanical handling preferably should be only each other On the spot work.Door handle then can work in the case that electromagnetism unlocks thrashing simultaneously as emergency unlocking device. Such mechanical handling possibility for lock piece 26 combines Fig. 4 in the second embodiment of door lock locking system and says to 9 Bright.

As the simplified example of emergency release, Fig. 2 and 3 illustrates such a form of implementation, in this form of implementation, It is fastened with the tie rod 58 of flexibility, another (unshowned) end of described tie rod and the thick stick mentioned on joint on lock piece 26 Bar connects.When pressing under door handle, then lock piece 26 is moved to show in figure 3 by tie rod 58 from lock position shown in figure 2 In the unlocked position going out, and permanent magnet 34 and 38 guarantees to make lock piece be maintained in this position.Realize urgent by this way Unlock.When again decontroling door handle, tie rod 58 is loosely sagging.

Certainly, tie rod 58 is not necessarily, by joint and is connected with door handle, but described tie rod also can be otherwise Can get at, so as to realize the emergency release of door.

As another example, the emergency release system of the magnetic of a kind of unlocking tool 60 including rod of Fig. 5 and 6 diagram System, described unlocking tool is on one end with strong permanent magnet 62.When this permanent magnet 62 is inserted near lock piece 26 simultaneously And when then moving from left to right as illustrate in figs. 5 and 6, then at one of permanent magnet 62 and lock piece 26 or two Magnetic interaction between individual described permanent magnet 32 and 34 causes lock piece to be driven in unlocked position.

Locking the different running status sliding block 74 of 20 and the mating reaction of lock piece 26 shown in Figure 10 A-C.Described Image only again illustrates lock piece the 26th, slide block 74 respectively and closes the section of sheet material 24 for clearness.Described view is respectively It is to see to that be below in fig. 8 and sightless side in Fig. 7 and 9 top view.

First Figure 10 A is shown in normal condition when door is opened.Lock piece 26 is pulled completely in lock housing body 22 that is does not dashes forward Go out and exceed the plane closing sheet material 24.Slide block 74 does not couples with lock piece 26 regularly, but can transport in certain play Dynamic, but lock piece 26 will not be made to move together.To this end, slide block 74 is provided with laterally stretches side that sheet material 24 point on towards closing at it The head 74a going out, described head is in the corresponding breach 26d of lock piece 26.Breach 26d is along the fortune of lock piece 26 or slide block 74 Dynamic direction is longer than head 74a.This difference is capable of motion in breach 26d for the head 74a.When head 74a pastes with its front Leaning against on lock piece 26 or when described head abuts on lock piece 26 with the face of its backcut extending laterally, described head is along right The direction answered makes described lock piece move.On the side contrary with closing sheet material 24, lock piece 26 proceeds to pin-shaped segments 26b In, the end in described section face behind has groove 26c, the spring that slide block 74 is constituted together with correspondence is movably supported on institute State in groove.

The closed mode of door is shown in fig. 1 ob.In this condition, lock piece 26 is due to here unshowned permanent magnet And move in the opening 16 of stop sheet material.Slide block 74 does not change its position, described position relative to the situation shown in Figure 10 A Next it is also referred to as primary importance.By the motion of lock piece 26, head 74a abuts in locking with its lateral protuberance now On part 26.

Unlocked position is shown in fig 1 oc.For release door, slide block 74 from primary importance out away from closing sheet material 24 ground Move in the second place and move lock piece 26 in lock housing body 22 at this.Subsequently, slide block 74 again moves at Figure 10 A Shown in primary importance in, thus lock piece 26 is released and door prepares for next closing process.

Another embodiment of lock 20 is given in figs. 11 and 12 again, and this another embodiment illustrates according to Fig. 7's-10 The composition further of lock.It is identical or identical that identical reference represents as in as described before figure in these figures again The element of effect.

Figure 11 A and 12A illustrates a part for lock 20 respectively with the top view seeing the side of the lock 20 being opened to side cover.Figure 11B and 12B illustrates lock 20 with the sectional view along the cutting line A-A providing in Figure 11 A or 12A respectively.Figure 11 C and 12C is class It is similar to the top view of Figure 11 A, 12A, but see the opposed side to lock 20.In Figure 11 D and 12D, lock piece the 26th, slide block 74 It is separately depicted in the position identical with the position that these elements are also had in Figure 11 C, 12C with motor 70.

The view of Figure 11 C and 12C illustrates the guiding in guiding gap 23 of lock piece 26 and slide block 74, described guiding gap It is formed in lock housing body 22.Slide block 74 has guide tabs 74c for this purpose, and described guide tabs also can be seen that in fig. 8.Lock Stop member 26 has two guide tabs not represented with reference.

Being provided with additional running status in the lock 20 of Figure 11 and 12, described running status is followed and is illustrated in fig. 1 ob Closing process.First the lockup state illustrating in fig. 1 ob illustrates in Figure 11 A-D for this embodiment again.

From this state, slide block 74 is moved to towards the direction closing sheet material 24 in the 3rd position by motor 70 and so It is pressed into lock piece 26 among opening 16 on one's own initiative.Thus obtained state is given in Figure 12 A-D.

When lock piece 26 is with the pattern inclination of dead bolt, described press-in causes the active of door to be closed, when described closedown, and door Page is pressed on door seal device.Such closing process for example may be adapted to stop the mistake in the gap between doorframe and door Journey, or close door with being suitable to special sound insulation.

It can be stated that after the active completing lock piece 26 is pressed into, make slide block 74 again move at Figure 11 A-D or figure In primary importance shown in 10B.This has the advantage that, i.e. when then turning on, reach more quickly slide block 74 Position shown in Figure 10 C.On the contrary, when regulation is retained in slide block 74 in the pushed position of active, then this advantageously causes The relatively reliable closed mode of door lock 20.When motor 70 is self-locking, the speed change gear that such as its mode is integrated has worm gear During worm gearing, then the latter is especially suitable.Other mechanisms alternatively also can be utilized to realize：Slide block 74 and therefore locking Part 26 is reliably retained in occupied position.For example can be provided with the electromagnetically-operated for lock piece 26 and/or slide block 74 Lockable mechanism.

In order to make slide block 74 can move to first and second and the if desired the 3rd in position, the location recognition of slide block 74 is Favourable.

In a kind of design of lock 20, location recognition can be carried out indirectly by the running current of detection motor 70. The position (slide block 74 stands mechanical stop in this position) especially illustrating in fig 1 oc and extruding again in Figure 12 A-D Position can be detected by this way well, because when slide block 74 overcomes mechanical stop to move, and the running current of motor Notable rising.

But work as on the position to be occupied of slide block 74, be provided with the additional mechanical that must be overcome by slide block 74 on this position During resistance, the primary importance shown in Figure 10 A, 10B and 11A-D also can detect by this way.Such additional Resistance for example can be obtained by the corresponding raising portion on shift motion and depressed part, and described raising portion and depressed part are at slide block On 74 or constitute on the element that slide block 74 moves relative to it.In the example illustrating in figs. 11 and 12, such raising portion 74d is constituted on slide block 74 with the form of that arrange and therefore elastic bridge.When slide block 74 moves, raising portion 74d is being slided The primary importance of block 74 contacts with the housing of motor 70, thus improves the resistance of motion of slide block.The resistance of motion of slide block 74 Change and emerge from the Motor Current of motor 70, primary importance thus can be detected.

It is alternatively possible to by sensor carry out slide block 74 position detection, for example by machinery switch or button and/ Or the combination of the permanent magnet moving together and fixing magnet sensor (reed contact or Hall element) is carried out slide block Position is detected.As another kind of alternative, motor 70 can be equipped with rotary angle encoder, thus from known reference position Setting out and determining position current all the time, described reference position for example by for example entering the second of slide block 74 at mechanical barriers Curent change when putting middle identifies.
