As best shown in figure 18, the metallic plate cup 50 of drawing includes base portion 51 and the cylindrical sleeve part 58 of ring-type.The outside dimension that sleeve part 58 has, this outside dimension is for inserting and loading cylindric aperture of door.Differing with traditional metallic plate lid (lid of the lock body 6 as shown in Fig. 2 of prior art), cup 50 surrounds axle return spring 15, and it is longer to be compared to the most conventional metallic plate lid.Base portion 51 provides spindle bearing hole 52 and cover retention groove 53.Cover retention groove 53 is directed at the groove 41 (Fig. 9) of end plate 40.

As shown in Figure 17 and Figure 24, end plate 40 and cup 50 are mounted on lock shroud flange 28 by metallic plate keeper 60.After installation leg 61 is installed on the rib notch 29 of lock cover main part 21.Fin 62 bends in the fin hole 54 of cup 50 and keeps recess 42 to be meshed with the lid of end plate 40.It is understood that after end plate 40 is directly axially inserted on main part 21, end plate 40 and cup 50 are held on main part 21 by keeper 60.

The structure (can be used alone or in combination) of several uniqueness is provided; to protect the intraware of lock body 19 to be subject to excessive torque, and by torque from lock body 19, particularly many cabins lock cover 20; it is delivered to edge list (trimpost) 232, is transferred to door.One of these structures are Torque plate 110.Another kind of structure is that the bar side on spindle bearing 120 rotates stop member 128.But, yet another construction is that torque shock ends starts block piece assembly.

Primarily with respect to Torque plate mechanism, Torque plate index slot 24 is formed in base portion 22 to receive the fin (or flange) 112 of Torque plate 110.Torque plate 110 (Figure 16) is similar to lock cover 20 and itself is formed by metallic plate.

As shown in figure 26, the fin (or flange) 112 of Torque plate 110 is directed in the respective torque plate index slot 24 (Fig. 6) of lock cover 20.The axial range that fin 112 has is enough to support that same cylindrical Lockset 10 (such as, 13/4 " to 2 ") in the scope of gate-width degree uses.The radially distal recess (or otch) 114 formed in Torque plate 110 is configured to form junction with Torque plate 110, and from Torque plate 110, torque is transferred to edge list 232 (Figure 28).Spindle bearing hole 116 makes Torque plate 110 be inserted into spindle bearing 120.

Torque plate 110 is installed between lock cover 20 and door decoration (doortrimrose) 240.In embodiment shown in Figure 28, Torque plate 110 is the assembly different from outer disk insert (roseinsert) 230.(not shown) in another embodiment, Torque plate 110 and outer disk insert (roseinsert) 230 form.

It is sent to Torque plate 110 from lock cover 20 assemblies is sent to the path of distally edge list 232 to door relatively radially 111 itself it is understood that this Torque plate structure provides load.

Go to the torque transfer structure of spindle bearing, it is formed at the bowhandle side in the drum type brake sleeve 122 of spindle bearing 120 and rotates stop member 128 (Fig. 6, Fig. 9) just past the external screw thread of drum type brake sleeve 122, prevent excessively rotating of the handle 12 (such as, Figure 28) of the applicable configuration of carrying in axle 70 or 80 from being undertaken by spindle bearing 120.

Will be understood that, in the embodiment that stop member 128 combines with Torque plate 110, the over torque put in outer axle 70 is sent to spindle bearing 120, it is sent to lock cover 20 from spindle bearing 120, it is sent to Torque plate 110 from lock cover 20, it is sent to edge list 232 from Torque plate 110, and is sent to door from edge list 232.

Yet suffer from Dasher and will use long tube spanner or other device, attempt the lock overtorque possibility to swarm into.The example that overtorque impacts can act on the power of abundance in order to not only to handle 12, and center roller bearing 120 rotates, flexure and be potentially even likely to destroy the column 33 (Fig. 6) of the lock cover main part 21 being directed in spindle bearing recess 134.The aiming at of Dasher using so impact forces outer axle 80 to rotate over its normal range, and thus forces key arbor assembly 140 to rotate and operate breech lock.

Particularly with Fig. 6 to Fig. 8, Figure 15 and Figure 19 to Figure 23, the power of noting now that turns to and hinders so impact, with the embodiment separating torque shock ends startup block piece assembly (or being mounted with the capture pieces of spring) 264 that retractor 250 combines.Referring initially to Figure 15.Retractor 250--is different from traditional retractor--and is divided into two parts assembly: cam ring starts retraction device 251 and external cam starts retraction device 260.Under normal circumstances (never the impact of overtorque), the retractor that the function of retractor 250 is similar with traditional.Retractor 250 is contained in lock cover 20.Retractor 250 is limited to does translational movement along or parallel to by the longitudinal axis with retracted position definition that stretches out of breech lock 285.Cam-engaging surface on the both sides of retractor 250 converts the rotary motion of corresponding door handle to linear latch retracting motion.Jaw 253 is provided as the tail end 282 (Figure 33) of engagement breech lock bolt assembly 280 so that inner and outer door handle 12 is retracted breech lock 285.If cannelure 254 is when such as door is closed and does not retract this latch so that tail end 282 is releasably fastened to retractor 250 and moves inward.

In one configures, inside door handle all the time can operation with this breech lock of retracting, even if during outside overtorque impacts or afterwards.Inside door handle combines to the inner axis of heart 70 (Figure 46) with retractor starting cam 71.The inner axis of heart 70 rotation in either direction makes the starting cam 71 of correspondence down press on the cam face 256 that cam ring starts retraction device 251, and pressure cam ring starts retraction device 251 in this process.

Under a kind of similar but less direct mode, outside door handle, when unblanking so that key arbor assembly 140 rotates.The retractor starting cam 71 being configured similarly on inner axis of heart 70 of the retractor starting cam 146 on key arbor assembly 140.Key arbor assembly 140 makes the starting cam 146 of correspondence down press on the cam face 263 that external cam starts retraction device 260 in the rotation of either direction, and pressure external cam starts retraction device 260 in this process.

External cam starts retraction device 260 and is formed with shoulder (or stopping elbow) 261, moves to a breech lock retracted position so that another mechanism--torque shock ends such as next discussed starts block piece assembly 264--hinders external cam to start retraction device 260.It is not triggered the overtorque of a blocking effect under normal circumstances, external cam start the pressure down of retraction device 260 its thrust is referred to 262 start at cam ring and push down on the corresponding thrust shoulder 255 of retraction device 251, pressure cam ring starts retraction device 251 and retraction breech lock 285 down in this process.

Block piece assembly 264 includes the block piece 265 being mounted with spring of at least one (and being preferably two).Each block piece 265 includes trigger unit (or fin) 266 and stop (or fin) 267, trigger unit (or fin) 266 and stop (or fin) 267 and is configured to be indexed to triggering accordingly and stopping in groove 301 and 302 (Fig. 7) in (indexinto) lock cover 20 respectively.As shown in Figure 25 and Figure 27, block piece assembly 264 combines to lock cover 20, and a block piece 265 is positioned on the outside of a rim lip 25, and another block piece 265 is positioned on the outside of relative rim lip 25.Each block piece 265 is by a biasing spring 268, for instance wire spring is applied with bias towards a blocking position.One finger of biasing spring 268 is located in this block piece.The relative finger of biasing spring 268 is located in lock cover 20.The centre position of biasing spring 268 outwardly (Figure 20-21) is to apply pressure to the inner surface of cup 50.

Block piece assembly 264 has the non-blocking orientation (Figure 20, Figure 22) of acquiescence and impacts triggering blocking position (Figure 21, Figure 23).Figure 20 and Figure 22 represents the relative position of the stop 267 during both is arranged.Figure 21 and Figure 23 represents the relative position of the trigger unit 266 in both is arranged.

Figure 21 represents stop 267, when when blocking position, how to prevent external cam from starting retraction device 260 and be depressed.The rotation of key arbor assembly 140 still makes retractor starting cam 146 rotate and pressing external cam startup retraction device 251.But, stop 267 and external cam start the stopping elbow 261 (Figure 15) of retraction device 260 and disturb mutually, external cam is made to start retraction device failure and stop it to move to breech lock advanced position, in one embodiment, stop 267 and external cam start retraction device 260 and are formed as sufficiently solid relative to retractor starting cam 146, if so that when acting on enough overtorque power, before stop 267 produces fault, retractor starting cam 146 will deformation or cut-out.

When seated, block piece assembly 264 is by keeper or keeper assembly 130--post keeping flange 126 prominent from the lock cover of spindle bearing 120 in Fig. 6 illustrates--, and keeper or keeper assembly 130 make trigger unit 266 outside, and are held in the non-blocking orientation of acquiescence.(in other embodiments, not shown, keeper assembly 130 can be the part of the discrete item not formed as one with spindle bearing 120).Figure 22 represents how trigger unit 266 and block piece 265 are held in non-blocking orientation by keeper assembly 130.Making spindle bearing 120 relative to when locking cover 20 rotation when overtorque impacts, keeper assembly 130 is abnormal to be rotated.How Figure 23 represents keeper assembly 130 once rotate, and no longer trigger unit 266 and block piece 265 is held in this non-blocking orientation.

In aforesaid way, block piece assembly 264 is rushed in by an overtorque and is arranged into stop and activate.Impacting as long as outer door handle is not subject to overtorque, block piece assembly 264 is held in this non-blocking orientation by the spindle bearing 120 being supported in lock cover 20 assemblies 20.But, when outer door handle is subject to overtorque impact, spindle bearing 120 is configured to rotate relative to lock cover 20 assemblies.Once rotate, block piece assembly 264 is no longer held in non-blocking orientation by keeper assembly 130.The block piece assembly 264 thus excited is similar to spring loader and snaps onto blocking position.

In this stop is arranged, block piece assembly 264 stops the conversion of motion of at least outer door portion of retractor assembly to be breech lock advanced position.It is understood that due to the separating property of retractor 250, block piece assembly 264, when in arranging in stop, do not stop this inside door handle to be retracted this breech lock.In another embodiment, retractor 250 will not separate, but then overtorque impacts inside door handle this breech lock of retracting also will be made invalid.

The example of cylindrical Lockset 10 it is applicable to focusing on key arbor assembly 140.Cylindrical Lockset 10 holds the key arbor assembly (including the arbor assembly that manually-operated machinery activates with electro-motor) of the different lock function of substantial amounts of support.

Two of many expected manual operation mechanical embodiments by way of example only, what Figure 36 and Figure 39 represented that tubulose key arbor assembly 140 includes having retractor starting cam 146 that folding the gets up keyboard 148 downward with folding rolls stamped sheet metal tubulose key axle 142.In the way of being similar to the retractor starting cam 71 of interior axle 70, when user rotates the outer door handle 12 of effectively combination, retractor starting cam 146 is configured on corresponding retractor sliding cam surface 256 to combine and operation.

Key axle 142 holds key axle block (keyspindledog) 160, tubulose block guide 170 and key axle compression spring 184.Key axle 142 is also provided with block traveling window (or opening) 150 or 156, to be capable of rotation and/or the axially-movable of block arm (dogarm) 162.

Block traveling window 150 or 156 is relative with the axially extending bar 144 of tubulose key axle 142, is positioned on the side identical with retractor starting cam 146 of key axle 142.By contrast, in traditional key arbor assembly, block moves opening and is positioned the side (and relative with any retractor starting cam) of the key axle identical with this bar.For example, Fig. 3 of the U.S. Patent No. of Eagan 6189351 represents block cam shedding, and this opening aligns with this key axle seam, and relative with the retractor starting cam of key axle.Therefore, overtorque (as when distorting door) can promote seam separately.Additionally, in traditional design, and block traveling opening (include, for instance, the T-slot (70) of Eagan) for opening.Therefore, radial peg (such as, the pin (60) of Eagan) needs locking stop to be remained in this key axle traditionally.In the embodiment of Figure 36-41, on the contrary, block traveling window 150 or 156 be completely enclosed (that is, close by the one of key axle 142 and continuously, non-solder, window edge surround completely).This further enhances key axle 142 and prevents overtorque and the key axle block 160 without pin key easy to use.

The block traveling window 150 and 156 of Figure 36 and Figure 39 holds handle or the lock function of standard (rotatable) and rigidity (or forever invalid) respectively.In the embodiment of Figure 36, block traveling window 150 is T-shaped, has a biasing force axial groove 152 that block 160 is moved axially overcoming compression spring 184, and makes the semicircle cartridge type cross recess 154 that block 160 rotates around the axle of key axle 142.

When block arm 162 is arranged in axial groove 152, outer axle 80 " key entry " key arbor assembly 140, so that they synchronous rotaries.In another way, when block arm 162 axially extends in axial groove 152, outer door handle 12 is effectively coupled to breech lock 285.Torque from outer axle 80 is sent to key axle block 160 by the interface between key axle block driver slot 81 and block arm 162.Torque is sent to key axle 142 by the interface between its block arm 162 and axial groove 152 by key axle block 160 further, and is sent to retractor starting cam 146 therefrom.

Among locking lockset, " locking " position docks definition by the block arm 162 of axial retraction with the side of the recess 134 of outer spindle bearing 120, to prevent the rotation of outer handle axle 80.In folding lockset, the position not being engaged rotates freely definition by the block arm 162 of axial retraction in cross recess 154.When not being engaged, the moment of torsion from key axle block driver slot 81 is sent to block arm 162 continuously and is sent to key axle block 160, but only makes block 160 rotate in axial groove 152.Due to axial groove 152 have significant, be preferably approximately semicircular angular range, therefore arrive the axial edge of cross recess 154 at block arm 162 before, other device (such as, rotating stop member 128 and/or keeper assembly 130) that is rotated through of outer axle 80 limits.Therefore, at a non-occlusal position, there is no that torque is sent to key axle 142 from outer axle 80, and therefore put on the effect that the torque in outer axle 80 loses the retractor 250 of operation separation.

In passing, the radial height of block arm 162 determines whether to it provide clutch or lock function.Key cylinder assembly 10 is provided for lock arrangement by higher block arm 162, because block arm 162 docks mutually with the side of the recess 134 of outer spindle bearing 120 in latched position, to prevent the rotation of outer handle axle 80.On the contrary, relatively key cylinder assembly 10 is configured to clutch configuration by the block arm 162 of low height, because the internal diameter of spindle bearing 120 skips the top of block arm 162.Uniquely changing into of needing to reconfigure key cylinder assembly 10 between locking and clutch configure uses to be had the key axle block 160 of suitable size block arm 162 and substitutes key axle block 160.

Comparing with the embodiment of Figure 36, in the embodiment of Figure 39, block traveling window 156 provides substantially semi-cylindrical shaped and the block traveling opening without branch's (such as, it does not have axial groove) to be used for the motion of key axle block arm 162.Therefore--no matter by the interference between block arm 162 and spindle bearing recess 134 (namely, rigidity decoration lock configures), or by free between the rotation stop member of additionally offer but inoperative rotary motion (that is, not forever being engaged decoration lock configuration)--the rotation that outer axle 80 (but being not held therein in arbitrary key cylinder 215) for good and all makes key axle 142 is invalid.The comparison sheet of Figure 36 and Figure 39 illustrate how standard lock be selected between ornamental arrangement and rigidity lock ornamental arrangement only impacted by the suitable key arbor assembly of selection, and more particular by except block traveling window 150 or 156, there is no the structural change of other assembly of cylindrical Lockset 10, have between the key arbor assembly of roughly the same configuration select and impacted.

Among both Figure 36 and Figure 39, the key operation of key cylinder 215 operates key axle 142 with the breech lock 285 that bounces back by--unrelated with any torque applied to external door axle 80--.This is because this key operation is by the torque tail end from key cylinder 215 or part 216 (Figure 33) of dishing out, the interface of part receiver hole 149 of dishing out by its butterfly shape with keyboard 148, it is sent to the key axle 142 retractor starting cam 146 with it.

Key axle block (or block lining) 160 is be installed as the metal assembly for around tubular block guide 170, and latter of which is biased away from keyboard 148 by key axle compression spring 184.Key axle block 160 includes sharing the sleeve part 164 of cylindrical outer surface with yoke portion 166, and relatively and away from the prominent block arm 162 of the U-shaped inner surface in yoke portion 166.The hole 169 of sleeve part 164 forms interface with the key axle 204 of the bar 202 of knob sub-component 200 (Fig. 5).

Tubulose block guide (or sleeve) 170 is steel part, including spring base and key mandrel bearing cylindrical portion 172 and drum type brake post portion 174.Key axle block 160 relies on the drum type brake post portion 174 of tubulose block guide 170 and can being embodied as to pivot in drum type brake post portion 174.Cylindrical portion 172 is compressed spring 184 for key axle and is defined inner tubular portion spring base 185, and the contained spring seat of this tubulose is such as formed with the tubular outer spring base of the tubulose inserted link (68) of Eagan and compares.

The axial length 155 (Figure 36, Figure 41) of cross recess 154 (Figure 36) or block traveling window 156 (Figure 39) are substantially greater than the axial length 163 (Figure 38) of block arm 162, but are only slightly larger than the addition of each axial length 165 and 167 (Figure 38) in this sleeve and yoke portion 164 and 166 (Figure 36).When locking stop guide 170 substantially pushes (by instrument) keyboard 148 in all modes, key axle block 160 can pass through cross recess 154 and be inserted in key axle 142 (or therefrom removing), in order to rely on the drum type brake post portion 174 of tubulose block guide 170.In addition, as shown in figure 38, the axial length 173 of the main cylindrical portion 172 of tubulose block guide 170, axial length 163 plus block arm 162, axial length 155 less times greater than the cross recess 154 (Figure 36) of semi-circular cylindrical, thus when fitting together with key axle block 160, it is prevented that tubulose block guide 170 is holded up from cross recess 154.In addition, as Figure 38 is further illustrated, the axial length 175 in drum type brake post portion 174 between the axial length 167 in the yoke portion 166 of block with the sleeve part of block and the axial length 165 and 167 being added in yoke portion 164 and 166 so that drum type brake post portion 174 by part but and not all in the way of extend in sleeve part 164.

It should be noted that the pivotable operation of block 160 promotion key axle 142, the disengaging between block 160 and block guide 170.When axial groove 152 rotate to be the key axle block driver slot 81 with axle 80 align time, if block arm 162 is held in cross recess 154, under the bias of compression spring 184 helps, the key-operated rotation that key axle 142 carries axle 80 relative to outer handle makes block arm 162 depart from cross recess 154 to enter in axial groove 152.

It should be noted that the structural support of cylindrical Lockset 10 than above exemplarily and the assembly of illustrative description various key cylinder assemblies widely.These assemblies include having the key cylinder assembly of significant structurally and functionally different key axle, block and block guide, and have the key cylinder assembly of difference and/or other assembly.For example, it is provided that the assembly of the various combination of lock function, relate to the assembly of two inner axis of heart or two outer axles, and the assembly of electronics, motor-driven configuration can be advised as key cylinder assemblies different in structure.

Focusing on a new knob capture component (knobcatchassembly) 100 with improvement, as shown in Figure 43-51.Can it will be appreciated that " knob is caught " is for conventional technical term, and both of the knob being suitable for keeping routine and eccentric rod caught by knob.

Knob capture component 100 (or can be described as knob keeper) includes knob capture pieces 101, knob catch spring 104 and chip shield 107.Knob capture pieces 101 (or be called catch body or driver) includes flange (or catching tongue piece) 102, and flange (or catching tongue piece) 102 carries the knob of axle 70 or 80 by handle and catches flange cross recess 76 and highlight.Knob capture pieces 101 also includes spring leg holes, and there is the lower limb 106 of knob catch spring 104 spring leg holes decline position, in order to promote the flange 102 of knob capture pieces 101 to enter to leader holding position.

The knob catch spring 104 of winding is formed to extend about complete 360 degree, curved section arcuation line essentially continuously around close to circular arc (Figure 50).In an alternative embodiment, this curved section extends around shorter circular arc, but still is greater than 180 degree.When the actuating power of release puts on knob capture component 100, the elastic deformation (and bloating) of the major part of knob catch spring 104 (as shown in Figure 51) segmental arc of winding can be caused.In contrast, showing the polygon spring (150) of explanation in the U.S. Patent No. of Best 4394821, the load that release activates bending between transverse direction and side lower limb (250 and 252) undertakes disproportionate.Here, by contrast, the load that release activates evenly, and is distributed along the most curved portions of knob catch spring 104.Circular arc spring projection (or block) 105 formed in the knob catch spring 104 of winding, relative with catch spring lower limb 106, knob catch spring 104 is located in the knob catch spring seat 77 of handle carrying axle 70 or 80.The lower limb 106 of knob catch spring 104 is held in the spring pin hole 103 of knob capture pieces 101 (or in an alternative embodiment, being held in recess or two independent holes or recess).

Knob is caught chip shield 107 and is inserted in curved shape, and then alignment and pressurization contact face-to-face with knob capture pieces 101.When being pressed into place, immediately the first fin 108 of flange 102 caught by knob, it is located in the T bar that flange cross recess 76 (Figure 24) caught by knob, and the second fin 109 of immediately catch spring projection 105 is adjacent to knob catch spring 104, is located in knob catch spring seat 77.

It is understood that knob capture component 100 is for more weak, or the cantilever spring steel wire knob of easy to quickly overstress is caught design (such as shown in Figure 42 A and Figure 42 B) and is improved at least significantly.Knob capture component 100 is also caught at No. 4394821 knobs of U.S. Patent No. of Best and is improved in configuration.As shown in Fig. 8 and Fig. 9 of latter patent.In the inner side overhead cam transmission of this axle on the polygon spring (150) of Best.Additionally, be compared to the transverse groove (146) that in axle 70 and 80 depicted herein, the designing requirement of the knob catch spring seat 77, Best of offer is longer, cause more weak axle.By in graphic it will be apparent that, seat 77 is compared to the cross recess that the knob capture component shown in Best provides, and has less profile.

Attention is turned to some other details, external screw thread 124 is provided on each spindle bearing 120, for receiving the corresponding female thread dish collar 245 (Figure 28), in addition, as best shown in Figure 28, handle (such as, bar or knob) 12 includes the sleeve 13 with classification, axially-extending portion 14, extension 14, under the configuration restriction that handle rotates, rotates stop member 128 phase with the handle side of spindle bearing 120 and docks.

Significantly, it is not similar that the spindle bearing (wherein, Fig. 4 is an illustration) of the expansion with routine is intended to surround axle return spring, and spindle bearing 120 (Fig. 6) has a relatively small profile.Similarly, it is compared to being designed as of routine and surrounds the dish of axle return spring and/or dish insert (wherein, Fig. 1 is an illustration), dish insert 220 and 230 and dish 240 (Figure 28), it is similar to spindle bearing 120 and there is a relatively small profile.

In many advantages, innovation disclosed herein provides the different aspect exceeding prior art, it is understandable that, one of them is the design realizing the prior art to be compared to intensity and the function with quite (and poor in some respects), and significant low cost manufactures the cylindrical Lockset of high intensity.For example, it is necessary to less and/or less expensive components.Lock cover 20, Torque plate 110, cup 50, keeper 60, axle 70 and 80, key axle 142 and dish insert 220 and 230 (not including edge list 232) such as can by the metallic plate manufactures of punching press.Other assembly (such as, mechanical component)--such as spindle bearing 120--be compared to the suitable foundry goods succedaneum of function significant less, weight is lighter.Need not foundry goods and need not be relatively big with expensive axle return spring cover.

Additionally, innovation disclosed herein makes it possible to produce is compared to the prior art with suitable intensity and function, potential lighter, and there is the high intensity cylindrical Lockset of a dish decoration device of profile that is less and that more separate.

Another advantage, for supporting lock function widely, reduces the difference of configuration and different configuration of component count simultaneously to greatest extent.

Another advantage includes more solid handle carrying axle 70 and 80, more solid key axle 140, shade assembly index Torque plate 110, the improvement rotating stop member 128 and keeper assembly 130 and knob capture component 100 that is new and that improve.

Above-mentioned all prior art literature are incorporated herein as general reference.

Certainly; the present invention also can have other various embodiments; when without departing substantially from present invention spirit and essence thereof, those of ordinary skill in the art can make various corresponding change and deformation according to the present invention, but these change accordingly and deform the protection domain that all should belong to the claims in the present invention.
