Description

Locking mechanism

Technical field

The present invention relates to locking mechanism, especially but be not only limited to relate to the door locking mechanism.

Technical background

There have been many years in lock and have had many different shapes, size and application.A special type of lock is the locking mechanism that is used for door, the cylinder locks that this admittance is driven by key or thumb-knob.Key or thumb-knob are rotated to drive latch extends with the corresponding recesses in the engagement doorframe along rectilinear direction, thus locking or unlatching door.

The operation of one type locking mechanism of prior art at first will be described.For example from the ASSA565 of ASSA, it used more than 30 years this locking mechanism, and still using today.

Fig. 1 has shown the lateral view of traditional locking mechanism 1, and this locking mechanism typically is contained in the lock housing 2.Lock housing 2 is fixed to lock 4, and this lock is fixedly secured on the (not shown).Lock housing 2 has the front side cap that is removed with the demonstration internal part, the identical rear side cover 2a that after internal part, sees, and in this shell, locking mechanism 1 comprises lock pin 6 and rod bolt 7.Locking mechanism 1 is used to drive one of both in the

latch

6,7 or both all to carry out straight line and moves between the primary importance (wherein

latch

6,7 stretches out lock 4) and the second place (after wherein

latch

6,7 is withdrawn into lock).

Lock housing 2 also comprises two circular opens 3,5 that are respectively applied for admittance cylinder follower 8 and handle follower 22 (will be described subsequently).Fig. 1 a has shown the front elevation drawing that is formed at first circular open 3 among protecgulum and the bonnet 2a, and each described lid comprises inwardly outstanding circular edge 3a.Between edge 3a, cylinder follower 8 is supported and is connected to two Supporting rings 10, thereby follower 8 and Supporting ring 10 rotate around circular edge 3a as a unit.

Cylinder follower 8 specifically illustrates in Fig. 1 b and comprises figure of eight groove 8a and toothed section 8c, near groove 8a place formation narrow positions 8b.Cylinder follower 8 is sandwiched between two Supporting rings 10, and one of them Supporting ring is shown in Fig. 1 d.Each Supporting ring 10 is formed by two metal parts that link together shown in Fig. 1 c.Accompany cylinder follower 8 between these Supporting rings, these Supporting rings 10 are given prominence to circular edge 3a centerings and are supported by edge 3a then, thereby Supporting ring 10 (with cylinder follower 8) is rotatable.When assembled as shown in Figure 1, cylinder follower 8 is located at and is admitted two cylinder locks, each one of every side of lock housing 2.Each lockset has the driving element with groove 8a engagement.

Cylinder locks can have two types.First type cylinder locks comprises key plug at one end and radially is installed in the driving element of the other end of key plug.Key plug is used to admit the key of described key plug of rotation and driving element.Second type cylinder locks comprises thumb-knob and at the similar driving element of the far-end of thumb-knob.The rotation thumb-knob also can make the driving element rotation.

When these two cylinder locks are assembled on each end of first circular open 3 respectively, driving element is used to mesh the narrow positions 8b of figure of eight groove 8a, reversing cylinder follower 8 and to make its motion, thereby the toothed section 8c of cylinder follower 8 drives intermediary element 12 with mobile lock pin 6 or rod bolt 7.

Intermediary element 12 comprises toothed section 12a and uses pivot pin 14 hinged, thereby intermediary element 12 is radially around pivot pin 14 rotations.Intermediary element 12 comprises shock surface 12b and is positioned at lug (lug) 12c among the hole 6a of lock pin 6.First spring 16 is provided, and it acts on moving with guide lug 12c in the 6a of hole on the lug 12c and first retainer 17.

When thereby cylinder follower 8 driven elements reverse when the counter clockwise direction shown in the arrow X is rotated, be rotated in a clockwise direction intermediary element 12 with the toothed section 8c of the cylinder follower 8 of the corresponding toothed section 12a engagement of intermediary element 12.Thereby lug 12c mobile makes lock pin 6 stretch out lock 34 and arrives " shutting the position ".

In order to make latch 6 turn back to lockset position of coupler, the key plug (not shown) of thumb-knob or cylinder locks is rotated, and reversing the groove 8a of cylinder follower 8, thereby cylinder follower 8 is along the clockwise direction rotation of arrow Y indication.Similarly, the toothed section 12a of intermediary element 12 is by the rotation toothed section 8c effect of cylinder follower 8, thereby toothed section 12a rotates in the counterclockwise direction.This rotates mobile lug 12c with driving lock pin 6, thereby latch 6 is withdrawn into lockset position of coupler.

Rod bolt 7 comprises the circular base 7b of bar 7a and expansion, and this pedestal is by handled follower 22 or actuated element 20 engagements.Second spring 24 is provided, and it is resisted against on the rod bolt 7 and second retainer 26, the rod bolt 7 thereby second spring 24 stretches out.

Handle follower 22 fits in second circular port 5 and comprises the square hole 22a of the axle (not shown) that is used to admit handle.Handle follower 22 further comprises having the adjutage 22b that impacts shoulder 22c, and this shoulder is used to mesh the pedestal 7b of rod bolt 7.When handle rotates (along clockwise direction in this case), handle follower 22 is along the direction rotation identical with the handle of rotation adjutage 22b, thereby impact shoulder 22c resists the pedestal 7b that the effect of the 3rd spring 28 (and second spring 24) drives rod bolt 7.Like this, by turning handle rod bolt 7 is withdrawn into after the lock.

When handle was released, the 3rd spring 28 faced toward second retainer, 26 bias voltage handle follower 22, thereby makes rod bolt 7 turn back to " door bolt closes " position.

Rod bolt 7 also can be driven by cylinder locks by actuated element 20, this actuated element comprise at one end first in abutting connection with shoulder 20a and the other end second in abutting connection with shoulder 20b.This actuated element 20 also pivot is installed in pivot pin 14 places movingly.First is used to mesh the shock surface 12b of intermediary element 12 in abutting connection with shoulder 20a.

Under the situation that lock pin 6 is as shown in Figure 1 withdrawn fully, the key that further clockwise rotates thumb-knob or cylinder locks causes rotating in the counterclockwise direction the toothed section 12a of intermediary element 12, thereby the shock surface 12b of intermediary element 12 bump first is in abutting connection with shoulder 20a and driving actuated element 20.This motion is converted into second rectilinear motion in abutting connection with shoulder 20b, this second in abutting connection with shoulder to drive the pedestal 7b of rod bolt 7 with the similar mode of impact shoulder 22c of adjutage 22b.Therefore rod bolt 7 is withdrawn in the lock housing 2.When discharging thumb-knob or key, second spring 24 is biased into rod bolt 7 door bolt once more and closes the position.

The shortcoming that locking mechanism 1 has is only can utilize the particular type cylinder locks.Fig. 1 e has shown the cylinder follower that is used for rod bolt 9 another examples of prior art, and this follower has the figure of eight groove 9a that forms narrow positions 9b, and this narrow positions is identical with narrow positions 8b.Because the structure of cylinder follower 8,9, further shortcoming is that every side of locking needs the cylinder locks of two separation, has therefore increased expense.

Therefore, use part annular cylinder follower 214 to make European double columnar form lock 206 to be used, can also keep the function of this tradition locking mechanism simultaneously.

Fig. 8 shows the second embodiment of the present invention, and wherein locking mechanism 300 is used to drive two rod bolts 302,304 and auxiliary bolt 306.Locking mechanism 300 also is contained in by two lid 308a, in the lock housing 308 that 308b forms.Lock housing 308 comprises opening 203, and this opening is suitable for being received in the European double columnar form lock of describing among first embodiment 206, and identical reference number will be used for this parts identical with first embodiment and other parts.

Fig. 9 has shown the lid 308a that separates, and 308b is with the decomposition diagram of demonstration according to the internal part of the locking mechanism 300 of second embodiment, and this locking mechanism comprises the part annular cylinder follower 310 with an abutment surface 310a.Driving mechanism adopts two meshing arm 310c, and the form of 310d replaces toothed section.Figure 10 a has shown the lateral view of the part annular cylinder follower 310 of second embodiment, and wherein dotted line is represented the first meshing arm 310c.

Figure 10 shows the cross-sectional side view of locking mechanism 300 of second embodiment of all parts assembling in place.Following description is with reference to figure 9,10 and 10a.

The first and the 3rd rod bolt 302,304 comprises bar 302a, the circular base 302b of 304a and expansion, and 304b, it is similar to the structure of the rod bolt 7 of first embodiment.These two rod bolts 302,304 are driven by transmission levers 312 (Figure 10), and this transmission bar bar pivot is installed on the end of first pivot element 313 movingly.Transmission levers 312 comprise the first meshing arm 310c that is used to mesh cylinder follower 310 first in abutting connection with shoulder 312a, mesh first rod bolt 302 pedestal second in abutting connection with shoulder 312b and engagement lever 314 with drive second rod bolt 304 the 3rd in abutting connection with shoulder 312c.First spring 318 is provided, and it is resisted against on first rod bolt 302, and also is resisted against on the side of lock housing 300 with outside bias voltage first rod bolt 302.

Can find out obviously that from accompanying drawing second rod bolt 304 is biased in the same manner as in the first embodiment, so handle follower 22 ' driving to second rod bolt 304 will not be described in a second embodiment with associated components.This description will concentrate on transmission levers 312 and how drive second rod bolt 304.

In order to drive first and second rod bolts 302,304, key 210 is inserted in the key plug 208 to rotate driving element 218 in the counterclockwise direction.As another selection, can use thumb-knob 212.Figure 11 and 12 shows the action of using key 210 to drive first and second rod bolts 302,304.

When key 210 is inserted in the key plug 208 and rotates, first abutment surface 310a of driving element 218 mate

annular cylinder follower

310 and 310 motions of driven cylinder follower.Therefore, in the meshing arm one, be the first meshing arm 310c in this case, engaged transmission lever 312 first in abutting connection with shoulder 312a to promote lever 312 towards the pedestal 302b of first rod bolt 302, up to second in abutting connection with shoulder 312b engages base 302b, thereby withdrawal rod bolt 302, as shown in figure 12.

Figure 12 also shows the 3rd engagement lever 314 in abutting connection with shoulder 312c driving by transmission levers 312.The engagement lever 314 that pivots around second pivot element 316 drives pedestal 304b then, thereby withdraws rod bolt 304 point-blank, and first rod bolt 302 is withdrawn in abutting connection with shoulder 312b by second simultaneously.

Auxiliary latch bolt 306 comprises brake component 306a at one end, and described end is connected to the groove of Connection Element 320.Connection Element 320 is again by the 4th spring 322 bias voltages, and when auxiliary latch bolt 306 withdrawals, Connection Element 320 is correspondingly withdrawn, and this has driven by the hinged latch elements 311 of pin 313.The far-end of Connection Element 320 is connected to transmission levers 312 then, thereby when activation lever 312 was driven by rotation driving element 310, auxiliary latch bolt 306 was also withdrawn, as shown in figure 12.When locking mechanism 300 is installed to when last and when this door is closed, these two rod bolts 302,304 are biased into along their door bolt in the respective aperture of the lateral column of doorframe by two springs 318,319 and close the position.Yet auxiliary latch bolt 306 does not have corresponding hole and remains on retracted position.This means Connection Element 320 withdrawals, this causes upwards driver card locking element 311.Latch elements 311 comprises the first extension 311a of the pedestal 302b that is used for " blocking " first rod bolt 302, and it makes first rod bolt have the function that is similar to " lock pin ".Therefore, when door was closed, if there is not key " release " latch elements 311, the user just can't open door so.

Latch elements 311 also can discharge by rotating thumb-knob 212, and this thumb-knob has the effect identical with using key release latch elements 311.When thumb-knob is rotated, first engagement and the

second meshing arm

310c, 310d is rotated as described in previous.The first meshing arm 310c carries out in the same way, and the second meshing arm 301d meshes the second extension 311b (as shown in figure 12) of the latch elements 311 of downward push card locking element.This action makes the first extension 311a break away from from the pedestal 302b of first rod bolt 302, thus " freeing " first rod bolt 302, thus remove " kayser " effect.

The locking mechanism 300 of second embodiment also comprises the quick trip lever 321 that is positioned on the lock 305.When first with during auxiliary latch bolt 302,306 withdrawal, this lever 321 can be adjusted so that first rod bolt 302 and auxiliary latch bolt 306 are locked in retracted position, and allows first rod bolt to play normal function and allow the user to open door by turning handle.Because the effect of auxiliary latch bolt 306, so this lever 321 can be used in and starts or stops " lock pin " function.Different with first embodiment, this also allows not use key and locks the door, and reason is that if the lock pin function is activated (by lever 321 is set to the tram) no matter when closing to the doorstep, this goalkeeper is locked automatically.

Like this, by the use of part annular cylinder follower 310, the locking mechanism 300 of second embodiment is suitable for admitting European double columnar form lock 206 to drive rod bolt 302,304.It is evident that the present invention also allows to use the cylinder locks of other type, this provides similar driving element to come drive part annular cylinder follower 310.

Described embodiment is not to be construed as determinate.For example, at the end of the direction of rotation shown in the described embodiment about lock housing 202,308.If use the other end driven cylinder lock 206 of thumb-knob 212 at shell 202,308, direction of rotation will be different.

Locking mechanism 200,300 also can be used for window, not merely is used for door.In this case, locking mechanism 200,300 can only comprise lock pin 6 ' or rod bolt 7 ', the cylinder locks that therefore is used to extend respective pins can only need key plug or thumb-knob.

Locking mechanism 200,300 can not comprise intermediary element 12 ' or transmission levers 312, when especially only having lock pin or rod bolt.Part annular cylinder follower 214,310 can directly drive latch to extend or this latch of withdrawing.

Described the present invention now fully, those of ordinary skill in the art is understood that the scope that can carry out many improvement to this and not exceed claim.
