With reference now to Fig. 2,, Fig. 2 is the exploded view that holds first actuator 7 of first key operated lock 14 and locking device 13.Operating locking means 13 is used for making knob 9 to become can not operating selectively.Such locking device can be any suitable form, and will describe a kind of concrete form at this from now on.Be preferably locking device and comprise key operated lock 14, in a kind of exemplary configurations, lock comprises main body or cylinder 15 and rotatably is contained in cylinder 16 in the cylinder 15.Can between cylinder 11 and cylinder 12, interact so that prevent cylinder 12 relative motions in known manner such as the brake bars (not shown) of pin brake bars, unless there is the key of correct processing to insert keyway (keyhole) (not shown) in the cylinder 12.As later description, it is interior so that prevent the motion of relative knob 9 that cylinder 15 can be contained in knob 9, and cylinder 16 can be connected to other part of locking device 13 with any suitable mode.
In a kind of typical layout, lock 10 and 14 all can be operated with the same manner, but this is not main.
Among Fig. 2 the locking device 13 of display structure comprise lock 14 and with two ratchets 18 of knob cooperation, they are controlled in the mode of explaining below.Though show two ratchets, should be appreciated that and to adopt independent ratchet 18.In the concrete layout that shows, each ratchet 18, so that can move on ratchet 18 longitudinal axis directions and can engage with the standing part of housing 4 for microscler and be slidably mounted on the knob 9, perhaps engages with part attached to housing 4.Ratchet 18 is positioned at the both sides, opposite of knob 9 rotations and can moves in an opposite direction from this radial axis ground.
When locking device 13 was inactive state, each ratchet 18 was completely contained in the cylindrical cavity C of housing, and these are presented in Fig. 3 and 4.The interior hub 20 that loads the knob 9 of ratchet 18 is positioned at hole C, and when ratchet 18 was in the shown position of Fig. 3, they did not hinder the rotation of knob 9.When locking device 13 was active state, the periphery (as shown in Figure 5) of hub 20 in ratchet 18 radially outwards moves and exceeds was so that engage 4 or part attached thereto.In shown layout, each ratchet 18 is contained in two lockings recessed 21 that are formed in the interior hub 20 of knob separately slidably, thereby and when ratchet 18 is in as shown in Figure 5 engagement position housing 4 or attachment feature, acts on simultaneously with knob and prevent knob 9 rotations.Should be appreciated that other layout and other form that also can adopt locking device.
In the concrete layout that shows, ratchet 18 motion be activated the control of device, the device of illustrating in the drawings is rotatable cam 22.Cam shown in the example 22 comprises that two of being formed on the periphery surface 24 are recessed 23, and is arranged as the relativeness on diametric(al).As shown in Figure 3, when locking device 13 is in inactive state, each recessed 23 inner end portion of accepting on the ratchet 18 separately.As shown in Figure 5, when locking device 13 was in active state, the inner of each ratchet 18 was near periphery surface 24.Tilt domatic 25 each recessed 23 and surface 24 between extend, when cam 22 with respect to hub 9 according to as arrow " A " shown in, during concrete direction rotation, making ratchet 18 progressively radially outwards mobile among Fig. 5.
Can between cam 22 and knob 9, any suitable connection be set so that impel cam 22 to respond cylinder with respect to the rotation of knob and rotate according to suitable mode.In the concrete layout that shows, cam 22 is positioned at the cylindrical cavity 26 (Fig. 2) of knob 9, so that can limit its rotation with respect to knob 9.Arm 27 is laterally outstanding from the external surface of cam 22, and between two blocks 28 and 29 that are formed in the knob 9.Relative motion between cam 22 and knob 9 is limited by the thickness of interval between block 28 and 29 and arm 27.Preferably as shown in the figure, there is a spring 30 to act between knob 9 and the cam arm 27, but can adopts other layout to reach this purpose so that normally force arm 27 near block 28 (Fig. 3,7 and 9).
Can observe from Fig. 3, ratchet 18 is inactive state when the relatively rotation place of cam 22 and knob 9 makes arm 27 engagement stopper 28, and this position will be called the primary importance of cam from now on.When cam 22 with respect to knob 9 rotation so that engage near block 29 or be positioned block 29 when contiguous (second place of rotation), ratchet 18 enters moving position as shown in Figure 5.Spring 30 trends towards making cam 22 to get back to Fig. 3 position and releasable holding device is set so that prevent this motion.
Refer again to Fig. 2, comprise the visual detector device 73 that to observe from assembly 1 inboard, can see that locking device 13 is in active state according to lock set of the present invention.The device indicating 73 that shows is a kind of preferred embodiments, and what it comprised engagement cam 22 is driven part 74.A shown end that is driven part 74 comprises a plurality of outstanding 75 of outstanding 76 on cams 22 that are bonded on.The other end that is driven part 74 comprises active indicator surface 71, and in use surface 71 is arranged in cup 77.Cup 77 lower end is suitable for being provided with window 70, is visible by this windows active indicator surface 71 when locking device 13 is in active state.
Still with reference to figure 2, shown device indicating also comprises and is driven the non-activity indicator spare 78 that part 74 separates.Non-activity indicator spare 78 can integrally form or provides by being driven part 74 with being driven part 74, and shown embodiment only is preferable selection.Non-activity indicator spare 78 comprises non-active indicator surface 79, and it in use is positioned at the vicinity of active indicator surface 71 in the cup 77.In use or non-active indicator surface 79 or active indicator surface 71 be visible by window 70 so that point out locking device be movable or inactive.
With reference now to Fig. 3,, shows among the figure that locking device 13 is in inactive state.Be driven part 74 and so locate, making non-active indicator surface 79 is visible by window 70 as shown in Figure 4.The rotation of cam 22 impels and is driven part 74, as shown in Figure 5, and by at cam 22 be driven driving between the part 74 and engage and rotate.The rotation that is driven part 74 makes active indicator surface 71 alignment windows 70 be in active state as shown in Figure 6 so that indicate locking device 13.
In shown concrete layout, for example in Fig. 3, the cam holding device comprises and can or shift out the parts of cooperative engagement with cam 22 shift-ins.Preferably these parts are lever 31 forms, and it is mounted for and can waves between cam holding position and cam release positions or move pivotally.The cam holding position shows in Fig. 5 and 6, and cam release positions shows in Fig. 7 and 8.Preferably lever 31 is connected to cylinder 16 so that rotate with this cylinder in addition.
In the concrete layout that shows, lever 31 is entrained by cylindrical capstan head 32, and capstan head is connected on the cylinder 16 so that with tube 16 rotations.Lever 31 embeds in the translot 33 of capstan heads 32 so that in cam holding position as illustrated in Figures 5 and 6 with move between the cam release positions shown in Fig. 7 and 8.For reaching the motion purpose, this motion is essentially pivoting action, and the horizontal wing 34 of each of lever 31 is arranged in recessed separately 35 of capstan head 32.Lever 31 is clamped in the capstan head 32 by cover plate 36 becomes assembly, and the upper surface of ledge 37 supporting levers 31 on cover plate 36 bottom surfaces promotes the pivoting action of lever 31.Also can adopt the pivot of other form to install.Below be described in the cooperation of reclinate projection 38 of lever one end and cam 22.
When lever 31 is in the cam holding position (Fig. 5 and 6), projection 38 is near a side of the ledge 40 that stretches out from cam 22 upper surfaces.Biasing device preferably forces lever 31 enter pivot position, engage at this position upper protruding block 38 and ledge 40, and biasing device comprises the spring 41 that acts between capstan head 32 and the lever 31 in the layout that shows in the drawings.
With reference to figure 2, the device indicating of demonstration comprises biasing device 80 again, is used for bias voltage and is driven the non-active indicator surface 79 of part 74 trend demonstrations.The biasing device 80 that shows is the coil torsion form of springs, and the one termination is combined in the groove 81 that is driven part 74, and the other end acts on the inner surface of interior hub 20.When cam when arrow " A " direction is rotated, the biasing device storage power.When lever 31 moved to release cam ledge 40 positions, shown in Fig. 7 and 8, compression spring 30 and biasing device 80 were with bias voltage cam 22 and be driven part 74 and rotate to inactive state separately.In case be in this position, non-as shown in Figure 8 active indicator surface 78 will be by window 70 as seen.
In situation shown in Figure 5, knob 9 is by ratchet 18 and housing 4 or engaging of other retaining element and rotation is forbidden in clamping.As previously mentioned, cam 22 is fixed on the knob 9, and therefore knob moves on arrow " B " direction relatively.Also have, lever 31 can not be around the axis rotation of cam 22, because it and being connected of cylinder 16, unless and cylinder 16 can not rotate it with respect to cylinder 15 and opened by appropriate key.
The lock release setting is used for making lever 31 to shift out with the obstruction of cam protrusion 40 and engages.In the concrete layout that shows, lock release is arranged as for the cam holding device has direct influence, preferably such influence obtains by rotatable cam member 42, cam member 42 forms the part of releasing devices and is connected can be from the lock 10 of peripheral operation, makes the rotation of its response lock cylinder 12 and rotates.As shown in Figure 2, such connection can comprise the drive rod 43 of noncircular cross section, and it at one end is bonded in the groove 44 of cylinder 12 ends, and is bonded in the rectangular opening 45 that forms by cam member 42 at its other end.
Cam member 42 is arranged at the side covering lever 31 of lever 31 away from cam 22.The cam projection 46 that is arranged on the cam member 42 has inclined cam surface 47, and when lever 31 was in the cam holding position, this cam surface was suitable for engaging the extension 48 near giving prominence to the lever 31 on plate 36.Cause the acting in conjunction of cam surface 47 and extension 48 owing to the operation of locking 10 causes the rotation of parts 42, make lever 31 be compelled to the position shown in downward pressuring spring 4 trend Fig. 8 step by step.
After describing the critical piece that shows the embodiment of the invention in the accompanying drawings, the operating process of this embodiment is described below.
When lock is in the off-position, cam 22, ratchet 18 and non-active indicator surface 78 will be located as illustrated in fig. 3.Knob 9 is rotary manipulation dead bolt 3 on demand.In this respect, knob 9 can be pressed the known way acting in conjunction by drive plate 49 with spring bolt mechanism.
If require hook knob 9 to prevent rotation, cylinder 16 usefulness appropriate key 50 are rotated towards arrow " A " direction.Cylinder 16 is turned over about 360 from position shown in Figure 3 to position shown in Figure 5 and is spent.Engage and near the side 39 of cam protrusion 40 in the decline lever lug 38 of this motion, thus the influence of actuating cam 22 resistance springs 30, make cam 22 from first position of rotation shown in Figure 3 to second position of rotation shown in Figure 5.
As a result, ratchet 18 is moved out of recessed 23 and hook knob 9 antagonism rotation.Cam member further rotation 22 cause the rotation that is driven part 74 and in window 70 show events indicator surface 71.
Cam 22 is prevented by the acting in conjunction of lever lug 38 and cam protrusion 40 with respect to the rotation of knob 9 in arrow " B " direction (Fig. 5).
Clearly the effect of constraint value of lever 31 can not prevent to rotate toward arrow " B " direction with key 50 rotating cylinders 16, and makes cylinder 16 turn back to Fig. 3 position from Fig. 5 position.On the other hand, the operation of outer lock 10 will be removed the effect of constraint value of leverage in the following manner.
The rotation of lock cylinder 12 causes cam member 42 to make corresponding rotation by connecting (describing with reference to Fig. 2).When cam member rotated in company with lock cylinder 12, cam surface 47 engaged extensions 48, thereby little by little promoted lever 31 influences of antagonism springs 41 downwards.The result causes lever 31 to take position shown in Figure 8 finally, and promptly lever lug 38 no longer hinders cam protrusion 40 motions.Cam 22 thus can be freely rotating on by arrow " B " direction with respect to knob under spring 30 pressure influences.The rotation of cam 22 causes and is driven part 74 rotation and shows non-active indicator surface 78 in window 70.Compression spring 30 can provide biasing force separately, but preferably should be assisted by biasing device 80.Ledge 40 can be taked as shown in Figure 7 the position with respect to lever 31 thus.In addition, the moving handle cam recesses 23 of above-mentioned cam 22 is placed on such position, ratchet 18 can inwardly be moved and takes inactive state.The inside motion of ratchet 18 can automatically take place, and the result who perhaps can be used as knob 9 rotations takes place.In this respect, the outer end of each ratchet can be circular or other shape, so that knob 9 applies strength with respect to the rotational motion of housing 4 to each ratchet 18, this strength has the ratchet of acting on 18 component longitudinally.
When cam 22 is taked position as Fig. 7, unless it will keep this position to be forced to shift out this position by the operation of lock 14 under the influence of spring 30.As a result, when lock 10 when operation knob locking device 13 automatically becomes inactive state, and remain non-activity until intentionally turn back to active state by locking 14 operation.
As mentioned previously, the part of describing before this 74 that is driven is the preferred embodiments of indicating apparatus 73, and has alternative device indicating 73.Fig. 9 illustrates the preferred embodiment 73 of other device indicating, and the peripheral ledge 82 of cylindrical cavity that wherein holds the knob 9 of cam 22 is suitable for comprising window 70.In the present embodiment, the bottom surface of cam comprises active indicator surface 71 (not shown)s at least, when it can represent that locking device 13 is in active state when window 70 is seen in ledge 82, as shown in Figure 10.Figure 11 shows the alternative form of another device indicating 73.Window 70 is arranged in the ratchet slide lock device 21 of knob 9 in the preferred embodiment of illustrating in Figure 11.The bottom surface of ratchet 18 comprises active indicator surface 71 (not shown)s at least, represents that locking device 13 is in active state when it can be seen by window 70, as shown in Figure 12.Fig. 9 and 10 or Figure 11 and the 12 two kinds of preferred embodiment cam and the ratchet that show in the operation of locking device 13, will move.Correspondingly but window 70 is with respect to position display indicator 71 when locking device is activity of cam 22 and ratchet 18.Cam and ratchet 18 also can comprise non-active indicator surface.
Preferably no matter non-active indicator surface still is an active indicator surface comprises fluorescent material so that show the state of locking device in the dark.
From above be appreciated that the invention provides a kind ofly be used for the user is transmitted the relative simple mechanism of locking device state and do not require the operability of user trial knob.
Can make various modification, variation and interpolation and the unlikely the spirit and scope of the present invention that depart to the present invention as previously discussed.
