Abstract

The invention relates to a lock with an operating device for a bolt (1), into which, in the open position, a staple (20) engages. The lock can be brought into lock-position manually, and the bolt (1) is spring-biased in locking-direction. Furthermore, the operating device (50 to 53) is connected with the bolt (1) by means of an electromechanical coupling device (30, 40, 60, 70). This particularity of this coupling device is that it creates a spring-actuated connection between the operating device (50 to 53) and the bolt (1) only when the bolt (1) is in lock-position, and only after an electric control command. The electric control command can be produced in particular by insertion of a coded card in a reader device, or without contact by means of a transponder.

Description

Lock

The present invention relates to a kind of lock, it has a man-operated mechanism that dead bolt is moved between latched position and released position, and one embeds dead bolt with system bolt that man-operated mechanism effectively is connected on described released position.

In this lock, man-operated mechanism normally is made of key.We also know a kind of so-called " card " formula lock usually; wherein man-operated mechanism is made of knob or door handle; but described handle is not to act on the dead bolt; but act on the latch that bears spring force on the locking direction; and have only reader in lock to read out effective insertion card and subsequently when electric mechanical bindiny mechanism sends automatically controlled instruction, described bindiny mechanism is the then syndeton of formation transmission power between latch and man-operated mechanism.

The present invention is based on such purpose: design above-mentioned the sort of lock, although can make it change its latched position over to by man-operated mechanism from its released position, but it only after detecting card that a process examines or the responder of examining, just allows to open in the opposite direction lock.

According to the present invention, this purpose is to realize with the man-operated mechanism that links to each other with dead bolt by electric mechanical bindiny mechanism by the dead bolt that bears spring force on locking direction, described bindiny mechanism is only only receiving also on the dead bolt latched position that automatically controlled instruction back is after forming the connection of transmission power between man-operated mechanism and the dead bolt, in case but dead bolt is positioned on its released position once more, it cancels the annexation of this transmission power at once.

Therefore, although man-operated mechanism allows dead bolt is brought into its latched position, it then breaks away from dead bolt and is connected, receives automatically controlled instruction up to electric mechanical bindiny mechanism, and then, it is between man-operated mechanism and dead bolt till being connected of formation transmission power.Automatically controlled instruction is sent by reader, and reader is contained in the lock usually and reads the card or the responder of insertion.Such reader is a prior art, thereby it is not a part of the present invention.

For example, the lock that is proposed be applicable to the safety cabinet of packing into, dressing room and the facility that only uses for individual or specific crowd in as Sang Na chamber, swimming pool, tennis venue, what for example situation came to this in many hotel facilities.By assembling identical reader, lock proposed by the invention can have and the supporting general structure of door lock.

Electric mechanical bindiny mechanism preferably includes the slide block and a pawl type interlocking mechanism that can move by man-operated mechanism, wherein dead bolt is guided in slide block movably, and pawl type interlocking mechanism makes slide block and dead bolt link to each other (claim 2) with transmitting power under connection status.Normally the man-operated mechanism of knob or handle for good and all links together at this and slide block, but slide block only after receiving automatically controlled instruction just with the dead bolt interlock.

Can advantageously make slide block overcome spring force ground and move into described released position (claim 3) from its resting position.As a result, this can make slide block and man-operated mechanism return its initial position or resting position.

Slide block can also overcome spring force from its resting position and move along locking direction, and it has cancelled the effective annexation (claim 4) between system bolt and dead bolt when being in its final position.For this reason, slide block for example can have an inclined-plane.When slide block when locking direction moves, the system bolt that this inclined-plane will bear spring force is lifted away from the bayonet socket that is opened in the dead bolt.Then, the spring force that acts on the slide block makes slide block and man-operated mechanism return resting position.

According to a preferred embodiment of the present invention, pallet interlocking mechanism comprises the pallet and the recess in dead bolt that are contained in rotatably about an axis on the slide block, and described axle embeds recess (claim 5) perpendicular to the principal plane and the pallet of this lock under connection status.Therefore, only need very little power to rotate pallet.

Can also improve the foregoing description further, promptly pallet is subjected to the effect (claim 6) of spring on the direction of dead bolt recess.In the spatial distribution scheme of suitable pallet and corresponding dead bolt recess, spring force provides the power that makes pallet change connection status over to.But pallet also can form such structure, and promptly it can automatically fall into the dead bolt recess because of action of gravity.But in this case, lock can not be applicable to L.H.flapped door and R.H.flapped door by making lock rotate 180 degree more simply simultaneously.

According to a preferred embodiment of the present invention, pallet contacts with a slide under its disengaged condition, and this slide can slip into one and unclamp the position (claim 7) that pallet forms connection status by electric mechanical mechanism.In this embodiment, act on electric mechanical driving mechanism on the slide such as coil or micro motor itself and only need low-power electrical energy.When the electronic component of lock was rechargeable battery, this was to physical dimension and battery life advantageous particularly.

In the simplest layout, slide be parallel to the slide block setting and can be parallel to slide block and move (claim 8).Make the setting-in degree of depth of lock very little thus.

Advantageously, pallet is a both arms fork (claim 9).So one of them lever arm is designed for the dead bolt recess and cooperates, and another lever arm contacts with slide under the pallet disengaged condition always, till the electric mechanical driving mechanism makes slide move into the released position.

Under connection status, slide block is shifted to along opening direction in the moving of its released position at it and is driven dead bolt, and the system bolt plays a role and keeps described dead bolt here and the slide block that returned its resting position forces to throw off itself and be connected (claim 11) of the transmission power of dead bolt on this released position.So, no matter whether electromechanical element plays a role, and guarantees that all the time dead bolt brought into its latched position by man-operated mechanism, but can not merely make dead bolt return its released position by mechanically actuated.

Man-operated mechanism is designed to rotatable parts and it has an interior pin (claim 12) of a guide groove that embeds slide block.In this case, pin can be designed to predetermined breakaway poing, thereby will cause destruction to whole lock construction with rough power.

In the improvement project of the foregoing description, the longitudinal axis of guide groove forming V-shape and relative slide block is symmetrical (claim 13).Which limit according to guide groove cooperates with the pin of man-operated mechanism, although it is constant to start direction, the slide block moving direction has changed, thereby lock can be used for R.H.flapped door or L.H.flapped door selectively.

The embodiment of the present invention lock shown in the drawings has wherein saved electronic component (except the electric mechanical driving mechanism), wherein:

Fig. 1 is the decomposition view of the necessary parts of lock performance function;

Fig. 2 is the vertical view of lock that expression is in the dead bolt of released position, wherein from being parallel to the angle of analysing and observe of locking principal plane housing is shown;

Fig. 3 is the view identical with Fig. 2, but its dead bolt is in latched position;

Fig. 4 is the view identical with Fig. 3, but its expression is situation about forming between dead bolt and actuating mechanism after being connected of transmission power;

Fig. 5 is the view identical with Fig. 4, but it shows the situation after dead bolt has just returned to the released position.

Fig. 1 shows dead bolt 1, and it is made of lock tongue body 10 and guide section 11.Lock tongue body 10 is the effect of wind spring 12 by compression.Guide section 11 has bayonet socket 13, and the spring-loaded system bolt 20 on a band inclined-plane 21 embeds this bayonet socket on dead bolt 1 released position.

In addition, guide section 11 has recess 15 and it can slide in a slide block 30, and an inclined-plane 31 that can cooperate with system bolt 20 inclined-planes 21 is arranged on a side of this slide block.On slide block 30, be provided with a latch 32.When slide block 30 when opening direction promptly moves right in the drawings, this latch compression is contained in the wind spring 33 in the hole on the side being located at slide block 30.

On opposite sides, slide block 30 has a recess, is provided with the fork 40 that can install rotationally around an axle in this recess, and wherein said axle is perpendicular to the principal plane of lock.Fork 40 is continuous therewith in an extension spring 41, and the other end of this extension spring is fixed on the slide block 30 and tries hard to make fork 40 to rotate to illustrated position, and on this position, a lever arm changes in the recess 15 of dead bolt guide section 11.

Reed 36 contacts with slide block 30 surfaces towards lock tongue body 10.Slide block 30 offers a V-arrangement guide groove 37 on its bottom side, the longitudinal axis of the relative slide block 30 of this groove is symmetrical.Guide groove 37 moves slide block 30 by a man-operated mechanism by disk 50 expression, is provided with a square hole 51 that holds square cotter 52 usefulness in the central authorities of described disk.Be provided with the pin 53 on one side of an embedding guide groove 37 at the edge of disk 50.

Slide 60 with the recess 61 that is used for fork 40 another lever arms is positioned at slide block 30 1 sides.Slide 60 is the effect of wind spring 62 by compression, and can overcome this spring force and spur a segment distance by a little electromagnet or coil 70 along this coil direction, and the armature lever 71 of described coil links to each other with slide 60 for this reason.

Fig. 2 shows and is contained in the above-mentioned parts of moulding in the lockmaking shell 80.Lock housing comprises that surrounds a tabula 81 that is used to hold the cavity 82 of battery and coil 70 usefulness automatically controlled circuit (not shown).In addition, tabula 81 is as the stop (referring to Fig. 5) of the latch 32 of dead bolt guide section 11, slide block 30 and slide block 30 itself.

Dead bolt is positioned on its released position, dead bolt is remained on the described released position by the system bolt 20 of the embedding bayonet socket 13 of spring force.Be subjected on the resting position of spring 33 and reed 36 (referring to Fig. 1) decision in it outside the slide block 30.Fork 40 changes in the recess that is opened on slide block 30 sides and lever arm and slide 60 contacts side surfaces by the left side, described slide be stuck under the effect of stage clip 62 its with resting position that housing muscle sheet 83 contacts on.The extension spring 41 that acts on the fork 40 is tightened up.

Now, when making man-operated mechanism 50-53 (imagination they behind the drawing) promptly the counter clockwise direction when with the aid of pictures is rotated a low-angle from the top along locking direction, slide block 30 inclined-planes 31 that cooperate with the inclined-plane 21 of system bolt 20 make to be made the bolt inclined-plane and lifts from the bayonet socket 13 of dead bolt 1 guide section 11.

The dead bolt 1 that so unclamps is pushed forward into latched position shown in Figure 3 by pretension coil compression springs 12.Meanwhile, slide block 30 is promoted by reed 36 and returns its illustrated resting position.All other movable part remains on its position as shown in Figure 2.Subsequently, although slide block 30 can move along opening direction because of clockwise rotating man-operated mechanism, it does not drive dead bolt 1.

Only when coil 70 received short current impulse shape control signal from automatically controlled circuit, slide block 30 just formed being connected of transmission power with 11 of dead bolt 1 guide sections.Then, coil 70 is drawn in position shown in Figure 4 with slide 60, promptly overcomes coil compression springs 62 spring forces by armature lever 71 traction slides.Thus, because the impetus of extension spring 41, fork 40 freely changes illustrated position over to.On this position, a lever arm falls into guide section 11 recesses 15, and another lever arm is arranged in slide 60 recesses 61.Simultaneously or the slide 60 that substantially side by side returns its resting position along and extension spring 41 identical turning to fork 40 generation effects.As long as need, the syndeton of the transmission power of slide block of Xing Chenging and dead bolt is just kept on position shown in Figure 4 always thus.

When man-operated mechanism is clockwise rotated, its pin 53 drive slide blocks 30 slide blocks again by fork 40 drive guide sections 11 and and then drive dead bolt 1, till dead bolt arrives released position shown in Figure 5.In this motion process, by the coil compression springs 33 of latch (see figure 1) tension in slide block 30.On this position, the system bolt 20 that bears spring force snaps in the bayonet socket 13 rapidly again.When unclamping man-operated mechanism, coil compression springs 33 relaxes, thereby makes slide block and and then make man-operated mechanism 50-53 return its resting position.In the return of slide block 30, fork 40 arms in guide section 11 recesses 15 slide along the side 15a (see figure 1) of this recess, and it goes back to its initial position parallel with guide section 11 thus again.So, after unblanking, the annexation of the transmission power that slide block 30 and guide section are 11 has just been cancelled automatically.Strain extension spring 41 this moment once more.In case when fork 40 ends that advance along the slide block moving direction were crossed the next-door neighbour limit of slide 60 recesses 61, fork just was in position shown in Figure 2, promptly contacts with slide 60 mutual aspectant side surfaces and lock fork by left side lever arm.This moment, lock was got ready for new lock operation.
