Description

The lock that a dead bolt that stretches out from lock box is arranged

The present invention relates to a kind of by claim 1 lock as described in the preamble, wherein, stretch out a dead bolt from lock box, its moves the effect of the door handle follower arm that the dead bolt tail of guiding can be by spring buffer and pulls back in lock box, and can by means of the manipulation by lock such as key, lock core, second follower after the system bolt lifts in advance forward and locking backward.

Known this type of lock on market as glass door lock.The dead bolt tail is round the tenon supporting of system bolt, and the system bolt is buckled on this tenon backward, and system bolt and locking socket of dead bolt tail intersect and stretch in the motor area of follower with a knuckle end.In addition, the system bolt is equipped with a locking projection, and it is in the front or the back of lock box shoulder block according to the position of dead bolt.In this design, dead bolt is realized moving by means of the door handle follower by the system bolt all the time.

The objective of the invention is will be at the technical lock that advantageously designs a kind of this type of lockmaking when realizing simple structure.

This purpose reaches by the feature of claim 1, wherein, can be designed to single arm(ed) lever by the system bolt that lifts of lock wing, it be provided with one wherein be inserted in dead bolt tail one side decide the journey pin decide the journey groove and it is around a column supporting that is arranged in dead bolt above-head lock box one side.

The result that this design brings has provided a kind of normally vertical lock, then its characteristic except simple in structure a kind of in the favourable design of lockmaking technical elements.The system bolt no longer is bearing on the dead bolt tail now, but round a column supporting that is located at the dead bolt above-head.Dead bolt act on during locking forward on the dead bolt head opening force now by decide the journey pin directly import into the system bolt and thereby import in the column of lock box one side, so can harmlessly bear big anti-torsion.Forward and backward the locking dead bolt need lift the system bolt in advance and discharge and decide the journey pin, thereby can live dead bolt by means of the lock wing locking that acts on the dead bolt tail.Deciding the journey groove is positioned at the free end side of lever tumbler and locks the wing application point substantially in the central.Obtain favourable leverage effects thus and add a kind of soft locking mode.In addition, the favourable lever tumbler that is characterised in that is with respect to lock box wall elastic buffer.Therefore lever tumbler is in the terminal location that it conforms with the regulations in accordance with regulations.Its permission dead bolt when pulling on the door that is equipped with this lock is dodged on the one hand; Stop its travelling backwards by lever tumbler during locking forward when dead bolt on the other hand.

Another favourable feature can think that the dead bolt tail has a fixedly connected with it promotion projection, and the arm of door handle follower acts on and promotes on the projection, promotes projection and shift out the tow-away zone when dead bolt is in forward locked position.Opposite with prior art, not only lock wing but also the door handle follower all acts on the dead bolt tail.The system bolt is discharged by the power that adds by the door handle follower.When dead bolt is not advanced to locked position, promotes projection and extend in the zone of door handle follower arm.Otherwise, door handle follower null after dead bolt is finished locking forward.Promote projection is meeting to also driving the arm of door handle follower owing to spring force in the dead bolt of pressurized, so make the door handle follower return its original position with conforming with the regulations all the time.

In addition, to the lockmaking technology advantageously, promoting projection has one to be designed to diagonally extending and to be used for the slide plane that contacts with the nose of arm.Therefore when retracting dead bolt, there is identical lever transmission ratio all the time with the door handle follower.Another favourable being characterised in that, the arm of door handle follower are remained along by spring and are parallel to the direction extension location that dead bolt moves.Directly be in and the work connection status that promotes projection when therefore, the door handle follower becomes its revolution.

In order to reach purpose of the present invention, a kind of lock with the dead bolt that stretches out from lock box, dead bolt moves the door handle follower arm that the dead bolt tail of guiding can be by spring buffer in lock box effect retracts, regulation in addition, and it is adjustable making the elastic force of the spring of door handle follower elastic buffer.Because this fact of case can be the door handle driver or sets a lever handle or a knob.If the door handle follower is equipped with the lever handle, then there is the bigger arm of force, institute is so that wish that spring force is bigger.Otherwise, then spring force can be adjusted into less value, so though be that knob still can rotate knob easily and comes locking if use knob.For this reason, can move the spring action point that is fixed on the lock box, this preferably can carry out from the lock box outside.Stipulate that in addition this spring is a tension spring that acts on the follower arm.In this case, the spring action that is fixed on the lock box o'clock is made of a pin that can move in lock box.In order to change spring force, the latter can move between two positions in a cannelure.Concrete condition is that pin is fixed in one of two terminal location by means of bayonet coupling.For this reason, the district is respectively scabbled at opposite side in the pin end, and they are parallel to cell wall when position is in the groove section that is located at locking closure and the groove of lock at the end therein extends, and arranges transverse to cell wall during another position in the groove section that cross section is widened.Therefore need only rotate pin in order to change spring force, make to scabble to distinguish to be in and the cell wall positions aligning.Pin can be shifted one's position after changeing 90 ° in advance.For this reason, at its end face a tool receptacle is arranged.It for example can be designed to the form of groove, so that for example insert crewdriver attachment.In order to prevent that pin is shifted voluntarily, the groove section design that cross section is widened has bearing surface, reclines with the marginal portion plane earth that scabbles the district.Regulation also in this scheme, dead bolt tail can be additionally by the operated lock wing after the system bolt moves in advance forward and locking backward.Advantage aspect guidance technology is to come from, make the dead bolt tail between the sidewall of two locks, reclining their the guiding and by tension spring along locking direction elastic buffer.At last, the present invention also has a favourable feature to be, the door handle follower has the fork-shaped breach in a definite space, and whereby round the backing pin in lock box one side.

longitudinal side wall

4,5 of lock box 2 extend with meeting at right angles.

The dead bolt tail 8 of guiding dead bolt 9 between lock box 2 interior two

sidewalls

4,5, dead bolt 9 preparation have oblique cutting face 10 ' dead bolt head 10 pass the through hole 11 of antetheca 7.Dead bolt tail 8 is a kind of fork-shaped designs.That short prong 8 ' on, an end of tension spring 13 acts on the pin 12 that from then on prong sets out.The other end of tension spring is round the lock column 14 at the end 3, so dead bolt 9 is subjected to the effect of spring force when direction is forward moved.

Another prong 8 " three times of nearly prong 8 ' length.Prong 8 " the inboard be formed with locking socket 15, that establishes a square-section at its rear decides journey pin 16.Deciding above the journey pin prong 8 " end region be shaped on a cannelure 17 that extends along the dead bolt moving direction, wherein insert a pilot pin 18 in the lock bottom side." have one to promote projection 19 in its free end design, it contacts with the arm 20 of door handle follower 21 dead bolt tail 8 prongs 8, and the door handle follower is contained in the lock end 3 and is parallel between the locking closure 22 of its layout at lock box 2 rear portions.Promoting projection 19 has a slide plane 23 with the diagonally extending of the nose 20 ' engagement of arm 20, and nose 20 when dead bolt 9 is in home position ' nuzzle below promotion projection 19 moves forward with obstruction free dead bolt 9.

Dead bolt 9 normal positions shown in Figure 2 are kept by lever tumbler 24.Lever tumbler 24 is designed to single-arm lever, it its face the narrow side of deciding journey pin 16 be shaped on two be in front and back position decide

journey mouth

25,26, they separate with central strut rail 27.In the normal position of dead bolt 9, central strut rail 27 is being decided the extension of journey pin front and thereby is being stoped dead bolt 9 to move forward.And then decide journey mouth 26, lever tumbler 24 designs one arc buildup area 28, it stretches in the locking socket 15.Buildup area 28 is application points of lock wing and extends in the central authorities of single arm type lever tumbler 24 substantially.The other end of lever tumbler 24 is bearing in above the dead bolt head 10 round the column 29 in lock box one side.25,26 in the journey mouth of being referred to of deciding all is in by the free end of lever tumbler 24 on the contrary, and this free end is shaped on knuckle district 30.Lever tumbler 24 is bearing on the projection 31 of lock bottom side by means of it, thereby lever tumbler 24 is remained on the definite home position.Compression spring 32 acts on the lever tumbler 24 and forces it to be in home position by Fig. 2.Compression spring 32 itself is bearing on the lock box sidewall 4.

Door handle follower 21 has the fork-shaped breach 33 in a definite space in itself and arm 20 opposed sides, and the backing pin 34 of lock box one side inserts wherein.Under the home position of lock 1, the position of door handle follower 21 as shown in Figure 2.This position is kept by spring 35, and spring 35 acts on the arm 20.Spring 35 is made movable spring.One end of spring is round the joint tongue 36 of arm 20.Otherwise in order to change spring force, the spring action point P that is fixed on the lock box is adjustable.For this reason, spring action point P can move.What spring 35 was related here is a tension spring.The spring action point P that is fixed on the lock box is made of a pin 37 that can move in lock box 2.The latter can move in the cannelure 38 of the lock end 3 and locking closure 22 between the two positions.The direction of cannelure 38 is extended towards the direction of door handle follower 21 arms 20.This cannelure 38 is designed to make pin 37 to be fixed on one of two terminal location by bayonet coupling.There is the opposed district 39 of scabbling pin 37 ends.Distance between them is slightly less than the distance of the cell wall 40 of the

lock end

3 and 41 extensions parallel to each other of locking closure 22 groove sections.Wherein, groove section 41 from the distance of arm 20 than near with respect to the groove section 42 of groove section 41 widening Design.The shape of the inwall of groove section 42 and pin 37 outer walls matches.If pin 37 advance the end of groove inlet section 42 and pin 37 made scabble district 39 perpendicular to the moving towards of cell wall 40 time, spring 35 has bigger elastic force, can be referring to the drawn position of the 37 usefulness solid lines of pin among Fig. 6.

For preventing that pin 37 is shifted voluntarily, groove section 42 designs of widening in the lock end 3 and locking closure 22 have bearing surface 43, are used to scabble district the plane of 39 marginal portions and recline.These bearing surfaces 43 extend perpendicular to cell wall 40.

After changeing 90 ° in advance, pin 37 is convertible into by the drawn position of solid line among the position shown in Fig. 6 chain-dotted line and Fig. 5, so spring 35 is used on the door handle follower 21 with less masterpiece.When setting the knob of not representing among a kind of figure, select this situation for door handle follower 21.If otherwise door handle follower 21 is equipped with the lever door handle of representing with chain-dotted line 44 in Fig. 1, then pin 37 is chosen as it and enters position in the groove section 42 of widening.For can be from the position of external conversion pin 37, the end face system tool receptacle 37 of pin 37 ', be used to insert screwdriver.

The locking forward or backward of dead bolt 9 can be by means of running through the locking closure 22 and the moulding lock core 45 at the lock end 3.Its lock wing 46 and lever tumbler 24 and with locking socket 15 cooperatings of dead bolt tail 8.

The working method of lock is as follows:

If among the figure not the door that is equipped with lock 1 of expression move its fastening position to, then, decide journey pin 16 in this case and in the scope of deciding journey mouth 25, move because oblique cutting face 10 ' dead bolt 9 is dodged towards the internal direction of lock is arranged.Then, in the closed position when door, dead bolt 9 advances to the home position that is in by Fig. 2 under tension spring 13 effects.From this position, can retract dead bolt by the operated door handle, can be referring to Fig. 3.For this reason, the nose 20 of door handle follower 21 arms 20 ' loading and thereby dead bolt 9 is inner mobile to lock on the slide plane 23 of dead bolt tail 8.The rotation displacement of door handle follower 21 leans against owing to prong 33 ' retaining on the backing pin 34 of lock box 2 one sides and is restricted.In these process medi-spring 35 tensionings.This situation also appears in tension spring 13 simultaneously that act on the dead bolt 9.If decontrol door handle 44, then door handle follower 21 returns the home position, and another prong 33 " kept off and leaning against on the opposite side of backing pin 34 this moment.In addition, tension spring 13 is retracted dead bolt 9 home position of shown in Figure 2 it.

When door is only in the closed position, can be by means of moulding lock core 45 with dead bolt 9 locking forward.When counter rotation lock wing 46, the lock wing be pressed on lever tumbler 24 buildup areas 28 and thereby lift lever tumbler 24, decide journey pin 16 tops thereby central strut rail 27 placed.At this moment, insert in the locking socket 15, just dead bolt 9 can be moved forward and is locked in position by Fig. 4 by locking wing 46.When pin wing 46 rotated for locking, it discharged lever tumbler 24, so lever tumbler 24 in spring force effect turning down, so its central strut rail 27 has arrived the back of deciding journey pin 16, makes and decides journey pin 16 and be in and decide in the journey mouth 26.So dead bolt 9 can not push back.Corresponding pressure backward imports in the column 29 of lock bottom side by lever tumbler 24.Have only with key-operated just might travelling backwards dead bolt 9, exactly, only in that lift lever tumbler 24 backs in advance and overcome the power of tension spring 13 could mobile dead bolt 9.

If used among the figure the not knob of expression on the position of door handle 40, then should reduce to act on the spring force on the door handle follower 21, in this case pin 37 is placed position shown in Figure 5.

In the latched position of locking forward, promote projection 19 and be in outside door handle follower 21 arms 20 movement locus, so do not contact with dead bolt tail 8 when door handle follower 21 moves by means of knob or lever door handle 44.

Another kind of form of implementation and first kind of form of implementation basically identical of expression in Figure 11 to 14.So same number designation of identical member.Difference is to adopt second second follower 47 that is contained in the lock end 3 and the locking closure 22 to replace moulding lock core 45 in this form of implementation.A kind of like this lock 1 ' can for example be used on the door in lavatory.Second follower 47 is equipped with lock wing 48, and the lock wing 46 of its effect and moulding lock core 45 is similar and set two shoulder blocks 56,57 in lock box one side.This lock 1 ' in, second follower 47 preferably is provided in the knob of an inboard.So dead bolt 9 is seen Figure 12 as retracting by means of door handle follower 21 in first kind of form of implementation.In addition, can be by means of the knob that belongs to second follower 47 at reveal locking dead bolt 9 forward, wherein, its lock wing 48 both with lever tumbler 24 also with dead bolt tail 8 cooperatings.Reach position shown in Figure 13 thus.Be equipped with lock 1 ' the unlatching of door, at first need be by means of second follower 47 with dead bolt 9 recession.Can dead bolt 9 thoroughly be retracted by means of door handle follower 21 then.

If door handle follower 21 sets lever door handle 44, then pin 37 is in by the position shown in Figure 11 to 13.So spring 35 is used on the door handle follower 21 with bigger masterpiece.When adopting knob to be used for door handle follower 21, pin 37 places the position by Figure 14.

Lock 1 by the another kind of form of implementation of Figure 15 to 17 " have a dead bolt 9 ', it only plays a latch.Dead bolt tail 8 only constitutes a prong 8 ".On it, also act on an extension spring 13 '.Lock 1 in this form of implementation " in do not have the system bolt.Secondly it is not arranged on the door handle follower 21 in lock box 2 back region.

Dead bolt 9 ' retract by means of act on prong 8 in central region " on follower 49 carry out.Joint tongue 51 actings in conjunction of the arm 50 of follower and dead bolt tail 8, the locking closure 22 that this joint tongue 51 draws in the part ' a cannelure in move.Door handle follower 49 is provided with one second arm 53 on the position relative with arm 50.Effect one spring 35 above it, it is counterclockwise afterburning to follower 49.Here the

shoulder block

55,55 of two lock bottom sides ' corresponding convex shoulder 54,54 ' actings in conjunction restriction followers 49 with two of follower 49 rotatablely moves.The spring action point P of lock box side has and above-mentioned two kinds of structures that form of implementation is identical.Just the orientation of cannelure 38 changes to some extent.It stretches along the direction of arm 53 now.

Extend in the groove section that a cross section is widened by Figure 15 and 16 spring action point P.This means that spring 35 is used on the follower 49 with bigger masterpiece.Therefore the latter preferably is equipped with a door handle.The position that can enter by Figure 16 by actuating doors handle follower 49, at this moment its arm 50 by joint tongue 51 with dead bolt 9 ' retract.

If follower 49 should set a unillustrated rotary spherical handle, must be offset the spring action point in this wise so, make pin behind prior half-twist in the insertion groove section 41.

Another kind of form of implementation at 1 of the lock shown in Figure 18 to 20 is used as the door handle follower of opening in first two form of implementation.Secondly the dead bolt 9 adopting in the third form of implementation '.But there is not follower 49 in contrast to this.Can only be as in opening first two form of implementation by means of door handle follower 21 with dead bolt 9 ' retract.Adjust to a bigger power by Figure 18 and 19 springs 35.Door handle follower 21 is equipped on door handle 44 in view of the above.The spring action point P of lock box side can be moved to the position of more approaching arm 20 when establishing a rotary spherical handle like this on door handle follower 21, and this describes in detail in first kind of form of implementation.

Also have a kind of form of implementation can be consistent with first kind of embodiment basically.But replace moulding lock core 44, in the lock end 3 and locking closure, establish the key socket of lock wing, but be equipped with the lock of system bolt by means of lock wing locking.
