Forward the P position to after 30 seconds, promptly from step S21 transfer step S30.At step S30, drive variable speed motor 29 by motor driver 28, control position VP is set to latched position PK.The result, sleeve 77 rotates by operating body 78, as Fig. 7 and shown in Figure 8, driving claw 71 actions, first sun wheel 60 is only locked on direct of travel with hub spindle 41, and lock pawl 92 moves, and the 3rd sun wheel 62 and hub spindle 41 only is locked into can not rotates on the direction opposite with direct of travel.After two sun wheels 60,62 lock in this wise, when gear crank 18 is rotated during rotating drive body 42, because first sun wheel 60 is locked on direct of travel, the biggest ground speedup just.But the 3rd sun wheel 62 can not be reversed, thereby sun and planet gear 44 is locked motionless.So, pedal plate and can not move even step, owing to can not utilize, just be difficult for taking place to steal car as bicycle.
At this moment, when by the hand propelled bicycle, though sun and planet gear 44 is locked, by the effect of free-wheel clutch 80, bicycle still can advance.But when sleeve 77 turns to latched position PK, bonding pad 105 on the spring shim 101 that sleeve 77 rotates is just pushed for the cam body 106 of the mechanism 100 of pronouncing, and moves left to position shown in Figure 10 and Figure 11 (B), (C) vertically from position shown in Fig. 9 and Figure 11 (A).Like this, the ratchet 111 of pronunciation pad 103 just turns round in the direct of travel one with 43 of hook tooth 113 engagement of hub shell 43 and hub shell.At this moment, the pronunciation sheet 112 of pronunciation pad 103 is is just come in and gone out in the pronunciation groove 109 of pronunciation cam 102 and is sent big conflict sound equipment.So, just can send big sound in case when lock-out state, be used to promote bicycle, thereby make robber's car become more difficult.
When password PW does not login, promptly be transformed into step S31 from step S22.At step S31, carry out password login process shown in Figure 14.At this, whether be operated in the step S41 of Figure 14 decision operation button 21.When operating operation button 21, promptly transfer to step S42, just each left sequence number L (tens sequence number) adds 1.At step S43, judge whether operating operation button 22.Before operating knob 22 not, return step S41, make left sequence number L add 1.When operating operation button 22, promptly transfer to step S44, make right sequence number R (units sequence number) add 1.At step S45, whether decision operation button 21 is operated once more.When operating operation button 21 not, return step S43, make right sequence number R add 1.When start-up function button 21, transfer to step S46, the sequence number LR of input is stored in the storage part 30 as password PW.So just, two figure places of having logined from [00] to [99] are password PW totally 100 sequence number LR.
At step S23, after decision operation button 21 has been operated when unlocking, promptly transfer to step S32.At step S32, identically when logining make left sequence number L add 1 with password.When 22 operations of decision operation button, just transfer to step S33 from step S24.Same at step S32 and password login, make right sequence number R add 1.At step S25, when the input sequence number LR consistent with password PW.Promptly transfer to step S34, control position VP is adjusted to a fast V1.Thus, by variable speed motor 29 sleeve 77 is rotated, navigate to speed V1, the lock pawl 92 that causes the 3rd sun wheel 62 is thrown off, and simultaneously, all driving claw 71-73 throw off.So all sun wheel 60-62 can both freely rotate with respect to hub spindle 41.The result is when stepping when pedaling plate, and the rotation of driving body 42 will send hub shell 43 to by first free-wheel clutch 80 to former state.
In the automatic speed changing of step S11 is handled, control position VP is set to speed change level corresponding to speed of a motor vehicle SP.Then, throwing off situation, each by direction speed change near one-level.At this, in the step S51 of Figure 15, according to the speed signal of car speed sensor 12, whether the speed of a motor vehicle SP that judges bicycle is below speed S1.At step S52, judge whether outpace S1 but under speed S2 of speed of a motor vehicle SP.At step S53, judge whether speed of a motor vehicle SP surpasses S2 and below speed S3.At step S54, judge the speed of a motor vehicle SP S3 that whether outpaces.
When the speed of a motor vehicle is a low speed situation below speed S1, promptly transfer to step S55 from step S51.At step S55, judge whether present control position VP is a fast V1.When control position VP is not speed V1, just transfer to step S56, by every next speed change level control position VP is adjusted to a fast V1.As outpace S1 and middle low speed situation below speed S2 is transferred to step S57 from step S52 of speed of a motor vehicle SP.At step S57, judge whether present control position VP is two-speed V2.When control position VP is not two-speed V2, move on to step S58, by every next speed change level control position VP is adjusted to two-speed V2.As outpace S2 and high speed situation below speed S3 moves to step S59 from step S53 of speed of a motor vehicle SP.At step S59, judge whether present control position VP is three fast V3.When control position VP is not three fast V3, move to step S60, by every next speed change level control position VP is adjusted to three fast V3.When the outpace high speed situations of S3 of speed of a motor vehicle SP, move on to step S61 from step S54.At step S61, judge whether control position VP now is four fast V4.When control position VP is not four fast V4, transfer to step S62, by every next speed change level control position VP is adjusted to four fast V4.
At this, by variable speed motor 29, when being connected with hub spindle 41, first sun wheel 60 becomes four speed, be input to the rotation of driving body 42 from miniature gears 47, promptly according to the determined maximum over-speed gear ratio speedup of the number of teeth of the first gear 63a, the second gear 63b and the gear ring 64 of first sun wheel 60, planetary wheel 63.Send hub spindle 43 to by second free-wheel clutch 81.When selecting second sun wheel 61 to connect, become three fast V3 with hub spindle 41, and the rotation of driving body 42 is passed to hub shell 43 promptly by second sun wheel 61, the second gear 63b of planetary wheel 63 and the determined second largest moderate over-speed gear ratio speedup of the number of teeth of gear ring 64 through second free-wheel clutch 81.When selecting the 3rd sun wheel 62 to be connected, become two-speed V2 again with hub spindle 41, and the rotation of actuator 42 passes to hub spindle 43 promptly by the 3rd sun wheel 62, the 3rd gear 63c of planetary wheel 63, the determined minimum over-speed gear ratio speedup of the number of teeth of the second gear 63b upper ring gear 64 through second free-wheel clutch 81.When not selecting arbitrary sun wheel 60-62, then become 1 fast V1 as previously mentioned, and the rotation of driving body 42 is directly passed to hub shell 43 again.
In addition, when not selecting sun wheel, become with respect to hub spindle 41 along relatively rotating in the opposite direction with row the place ahead.When carrying out speedup when having selected arbitrary sun wheel by sun and planet gear 44, driving body 42 and hub shell 43 promptly relatively rotate along removing the direction that first free-wheel clutch 80 combines.
In the hand gear of step S11 is handled, be to make the one-level speed change by the operation of operating knob 21,22 at every turn.In the step S71 of Figure 16, whether decision operation button 21 is operated.In step S72, whether decision operation button 22 is operated.If operating knob 21 has been operated, promptly move on to step S73 from step S71.At step S73, judge whether present control position VP is four fast V4.As now control position VP during, move on to step S74, not speed change and keep four fast V4 at four fast V4.When present control position VP is not four fast V4, just transfer to step S75, make control position be limited to a step and shift at a high speed level one side.Operating operation button 22 promptly moves on to step S73 from step S71.At step S73, judge whether present control position VP is a fast V1.When present control position is a situation at a fast V1, promptly move on to step S77, not speed change and keep a fast V1.When present control position VP is not the situation of a fast V1, promptly transfer to step S78, control position VP is only shifted to low speed turbine stage one side with a step.In addition, when carrying out above-mentioned speed change, compare with the position data that is pre-stored in each operating position in the storage part 30, carry out the positioning control of variable speed motor 29 by testing result with control position sensor 26.
Like this, in form of implementation 1, after scale 23 enters the stagnation of movement mode by operation, just think that the password inputed just keeps the stagnation of movement mode with the password of login when inconsistent, the releasing that therefore is difficult to include simply the anti-joyride device of lockout mechanism 90 is operated.
In addition, after scale 23 enters the stagnation of movement mode by operation, in by lockout mechanism 90 locking sun and planet gears 44 because pronunciation mechanism 100 can pronunciation, thereby not only step pedal plate after bicycle can not take action, and just can pronounce when promoting bicycle.Therefore can reduce the robbery accident of bicycle as much as possible.
Form of implementation 2
In last form of implementation, be between sun wheel 62 and the hub spindle 41 lockout mechanism 90 to be set in relative rotation, it is antitheft that pronunciation mechanism 100 is set between hub spindle 41 and hub hub shell 43 in addition, but also can between hub spindle 41 and hub shell 43, promptly travel between the parts in relative rotation, the anti-joyride device 85 with function of pronunciation and lock function is being set.
As shown in figure 17, built in type speed-variating hub 10a has and makes it possess the anti-joyride device 85 that lock function is arranged in the pronunciation mechanism 100 of Fig. 4 except that function of pronunciation again.Like this, lock pawl is not set in sun wheel 62.Except that anti-joyride device 85, other structure is all identical with form of implementation 1 with operation, omits its explanation.
Moving-member 103a has discoideus flange part 115 and along the integrally formed cylindrical portion 116 of interior all sides of flange part 115.In flange part 115, radially be provided with stage portion 115a midway, and lock ring 114 can free rotation ground supporting in stage portion 115a.In addition, on the face relative of the face relative of flange part 115 and lock ring 114 with lock ring 114 with flange part 115, as shown in figure 21, be formed with radial jog 114a (only show and understand on lock ring 114 1 sides) respectively, owing to formed such jog 114a, along with the friction force increase of lock ring 114 and moving-member 103a, they are just sounded when relatively rotating.
As shown in figure 21, four jut 116a are arranged on the inner peripheral surface of cylindrical portion 116.Jut 116a can be coupled among four groove 41c that form on the outer peripheral face of hub spindle 41.Like this, moving-member 103a is convenient to hub spindle 41 upper supports and is become to rotate but can move freely vertically.Form screw thread and engagement groove on the outer peripheral face of cylindrical portion 116.Hold-down ring 117 is installed on the outer circumferential side of cylindrical portion 116 as shown in figure 18.Hold-down ring 117 becomes can not rotate at cylindrical portion 116 upper supports but can move freely vertically, can be with lock ring 114 contacts.In addition, the stubborn hold-down nut 118 that closed on the right part periphery of cylindrical portion 116.Between hold-down nut 118 and hold-down ring 117, be provided with disc spring 119.
At this, the amount of being screwed into by regulating hold-down nut 118 is to the pressure touch of regulating disc spring 119, adjusts the friction force between the flange part 115 of lock ring 114 and moving-member 103a via hold-down ring 117, and retrained the rotation of hub shell 43 arbitrarily.For example when making friction force maximum by disc spring 119, can make hub shell 43 become the lock-out state that almost can not rotate.On the other hand, if friction force is reduced, the power that then retrains hub shell 43 rotations dies down, and hub shell 43 just can be rotated relative to hub spindle 41.Even but under these circumstances, be under the active state at disc spring 119 and also can produce friction force, compare with freely rotating, rotate and be subjected to constraint.In this form of implementation, can with hub shell 43 rotation of trailing wheel 7, the power of the effect by adjusting disc spring 119 can freely be constrained to it from substantial and lock state to the approximate state that freely rotates.
As shown in figure 21, be formed with serration 114b on the peripheral part of lock ring 114, they can be with the serration 113a engagement that forms on hub shell 43 inner peripheral surfaces.
In the anti-joyride device 85 that constitutes like this, when sleeve 77 is turned back to latched position PK from shift position, the bonding pad 105a of the spring shim 101a that rotates with sleeve 77 just moves in cam part 108a.When mobile, the moving-member 103a and the translating cam 102a that are moved spring 104a effect just are shifted to the right to position shown in Figure 19 and Figure 20 (B) from position shown in Figure 18 and Figure 20 (A) to bonding pad 105a in cam part 108a.At this moment, the serration 114b of lock ring 114 just meshes with the serration 113a of hub shell 43, and the rotation of hub shell 43 makes the constraint of the friction force that is subjected to lock ring 114 and moving-member 103a.At this moment friction force can by the amount of being screwed into of hold-down nut 118 regulate disc spring 119 application force and at random the change.So, pedal plate even step, trailing wheel 7 yet can not rotate or be difficult to rotate.
At this moment, if rotate hub shell 43 forcibly, just moving-member 103a and lock ring 114 relatively rotate, and jog 114a just makes lock ring 114 with moving-member 103a vibration and send the big vibration sound.Like this, owing to promote bicycle or step to rotate hub shell 43, just order is sent the big sound and is difficult for stolen when in lock-out state.And, even because of faulty operation cause travel in mistake when sleeve 7 placed latched position because the rotation of frictional constraint trailing wheel 7 is arranged, trailing wheel 7 can be not locked sharp.
In form of implementation 1 owing to be that sun wheel is locked, when sleeve 77 is in latched position, though step pedal plate after bicycle can not move, bicycle just can be taken action when promotion.And in form of implementation 2, because hub shell 43 is directly to link on the hub spindle 41 and locked, even remove to promote bicycle, because the rotation of hub shell 43 (trailing wheel 7) suffers restraints, it is also very difficult to promote bicycle, also just more difficult stolen.
Form of implementation 3
In above two forms of implementation, be that built in type speed- variating hub 10,10a with motor driven operating body 78 is that example describes but also available speed change cable connects variable speed operation portion and operating body, power operation by variable speed operation portion rotates sleeve, carries out variable speed operation and antitheft operation thus.
In Figure 22, the 9a of variable speed operation portion has the main part 160 that becomes one with right side brake rod 16 and the operating portion 161 that is installed in the main part 160 free to rotate.Be provided with the circular display part 162 that is used to show shift position and stagnation of movement position etc. in the main part 160, and the locking part 163 that when operating portion 161 is positioned at the stagnation of movement position, keeps this state.
As shown in figure 23, locking part 163 has cylinder locks 170, the locking cam 171 that rotates with cylinder locks 170, drives the lock body 172 that moves and make the leaf spring 173 of lock body 172 towards the right-hand effect of Figure 23 for locking cam 171.
Locking cam 171 is avette parts, by the rotation of cylinder locks 170 in directly over Figure 23 (A) shown in speed change the time position Figure 23 (B) of common position, 45 degree that turn left from common position shown in rotate between the latched position shown in release position and Figure 23 (C) of turning 90 degrees from the right side, common position.
Be formed with on the end face of the agent-oriention portion of operating portion 161 when latched position can be for the engagement groove 166 that cooperates in conjunction with projection 174 with in position usually and combine the shifting chute 167 that projection 174 is faced.The projection 168 that shifting chute 167 and engagement groove are 166 can be used as retainer under common motoring condition, by with match in conjunction with projection 174, even start-up operation portion 161 can not enter the stagnation of movement position from shift position yet.
(during Figure 23 (A), owing to be positioned at shifting chute 167 in conjunction with projection 174, the above-mentioned variable speed operation 9a of portion can make on any that operating portion 161 can be in four shift position and rotate when cylinder locks 170 is in unlocked common position.Left-handed turning is crossed 45 degree in key insertion cylinder locks.Then locking cam 171 is done same the rotation and is in the release position.At this moment, resistance leaf spring 173 added power make lock body 172 shift to left among Figure 23 (Figure 23 (B)).Therefore, join and the arrested state that produces is disengaged by projection 168 with in conjunction with projection 174, operating portion 161 can turn to the stagnation of movement position.When operating portion 161 is forwarded to the stagnation of movement position, relative with engagement groove 166 in conjunction with projection 174.Under this state, with key right-hand revolution 135 degree, locking cam 171 rotates too and is configured to latched position from the release position.At this moment, application force lock body 172 left in Figure 23 owing to leaf spring 173 moves.(Figure 23 (c)).So, being coupled in the engagement groove 166 in conjunction with projection 174, operating body 161 is locked into and can not rotates.Under this state, key to be extracted from cylinder locks 170, locking cam 171 promptly keeps suspended state in latched position.
In order to remove suspended state, on the contrary, key can be inserted in the cylinder locks 170, with key left-hand rotation 135 degree, locking cam 171 is placed the release position.Like this, lock body moves to left, and operating portion 161 can rotate.After operating portion 161 is placed arbitrary shift position,, allow locking cam 171 be in common position with key right-hand rotation 45 degree.Under this state, by leaf spring 173 added power, lock body 172 moves to right, and then places in the shifting chute 167 in conjunction with projection 174.At this moment, as previously mentioned, operating portion 161 is limited to and can moves on four shift position.So, even misoperation can not enter the stagnation of movement position yet.In this case, pulling up key begins by bike.
As shown in figure 24, with shown in Figure 17 identical, different is that the speed change cable directly links to each other with operating body 78 to the structure of built in type speed-variating hub 10b basically.Specifically, in form of implementation shown in Figure 17 2, operating body 78 is by motor 29 swings; And in this form of implementation 3, be to make operating body 78 swings by the speed change cable.Other structure is identical with form of implementation 2, omits its explanation.
In form of implementation 3, when the operating portion 161 that makes the 9a of variable speed operation portion turned to the stagnation of movement position, along with the rotation of operating body 78, sleeve 77 turned to latched position PK, so the rotation of built in type speed-variating hub 10b suffers restraints, and hub shell 43 is pronounced when rotating.So, identical with aforementioned two kinds of forms of implementation, be difficult for having things stolen, can prevent the stolen of bicycle.Just can keep these states when also in a single day placing latched position, have only when opening cylinder locks 170, just can get back to shift position by cylinder locks 170 owing to operating portion 161.Therefore, it is very difficult wanting to untie the anti-joyride device 85 that is in antitheft position, more is difficult for making car stolen.
Form of implementation 4
In first three form of implementation, all be that the built in type speed-variating hub 10 with trailing wheel 7 usefulness is the example explanation, but also can as Figure 25 all, anti-joyride device 85 is placed in the front wheel hub 120 of front-wheel 6 usefulness.
Front wheel hub 120.Have hub spindle 41b and be supported in hub shell 43b on the hub spindle 41b freely to rotate.Be formed with serration 113b on the inner peripheral surface of hub shell 43b.Sleeve 77a free to rotate is installed on the periphery of hub spindle 41b.The securing rod 121 that can not rotate is installed on the bottom of sleeve 77a.The structure of anti-joyride device 85 is identical with form of implementation 2, omits its explanation.
In this form of implementation 4, for example lock operation portion is arranged on the handlebar grip 15.The structure of this lock operation portion is identical with the 9a of variable speed operation portion in fact.Be that this lock operation portion also can have main part and operating portion.Operating portion also can move between stagnation of movement position and traveling-position, and this position of travelling is suitable with aforementioned a plurality of shift position.In lock operation portion, be provided with the key one class device that when the stagnation of movement position, can insert in the cylinder locks, and during, if no password is imported or key insertion etc. just can not be untied lock and return from the stagnation of movement position to traveling-position.This lock operation portion and securing rod 121 rotate sleeve 77a for cable is connected by lock operation portion.Moving-member is moved between locked.
Form of implementation 5
In aforementioned four kinds of forms of implementation, anti-joyride device all is provided in a side of among the wheel hub of wheel, but also can anti-joyride device 85a be located in the built in type speed change crank 130 of drive division 5 as shown in figure 26.
Built in type speed change crank 130 can carry out height two-stage speed change and locking, and it comprises: have the axis 132, left and right sides crank arm 133a and the 133b that are installed to the crank shaft 131 on cycle frame body 2 2a of medium-height trestle portion, sun and planet gear 134, with sun and planet gear 134 bonded assembly crank gears 135 and be located at anti-joyride device 85a on the sun and planet gear 134.
Crank shaft 131 is supported on the barrel-contoured axis 132 free to rotately, crank arm 133a and 133b is done and can not install rotationally by hold-down bolt 140 at its two ends.Axis 132 has the tubular support body 141 of supporting crank shaft 131, integrally formed box portion 142 and be located at mounting screw 143 in support body 141 left ends on the right-hand member of support body 141.Axis 132 is installed on the cradle portion 2a by the mounting screw 143 of tightening the support body 141 that is inserted in the cradle portion 2a, can not rotate on vehicle frame 2 owing to be installed to the fixed arm 144 in the box portion 142 simultaneously.
Sun and planet gear 134 has the gear ring 145 that is formed on the 142b of the portion inner peripheral surface, three planetary wheels 146 of gear ring ingear (only illustrating among Figure 27) therewith as shown in figure 27, and with planetary wheel 146 ingear sun wheels 147.
Framework 148 can integrally only be rotated at direct of travel for 131 one-tenth with crank shaft by driving claw 155.Then be formed with a plurality of radial engagement groove 148a on the left surface of framework 148.Planetary wheel 146 has canine tooth gear teeth 146a and pinion gear teeth 146b, canine tooth gear teeth 146a and gear ring 145 engagements, pinion gear teeth 146b and sun wheel 147 engagements.
Sun wheel 147 is installed on the crank shaft 13 free to rotately.The inside of sun wheel 147 is provided with driving claw 149, and by driving claw 149, sun wheel 147 direct of travel at crank shaft 131 is linkedly rotated.
On interior all sides of the 142b of tube portion of box portion 142, the conversion plectane 151 that can not rotate but can move freely vertically is installed.Conversion plectane 151 moves vertically by the swing of conversion rod 152.In addition, conversion plectane 151 also is applied by acting device not shown in the figures left towards Figure 27.But conversion rod 152 free swaying ground supportings have formed inclination cam (not shown in the figures bright) on the side that itself and conversion plectane 151 join in box portion 142, by swing conversion plectane 151 are moved vertically, and in the upper end speed change cable are installed.This speed change cable is installed in the bright variable speed operation portion not shown in the figures.For example there are high speed, low speed and stagnation of movement totally three positions in this variable speed operation portion, can lock on the stagnation of movement position to keep this position.This variable speed operation portion can adopt in the form of implementation 3 disclosed the sort of in fact.
Be formed with vehicle frame on the right flank of conversion plectane 151 and penetrate shape engagement groove 151a, can be with the engagement groove 148a engagement that forms on the framework 148.This engagement groove 148a, 151a have constituted anti-joyride device 85a with conversion plectane 151.On interior all side right-hand members of conversion plectane 151, be formed with conversion pawl 151b, can be used to make driving claw 155 not drive but can swing.In addition, on the outer circumferential side of conversion plectane 151, also be formed with and the 142b of the tube portion ingear tooth 151c of portion.
In having the built in type speed change crank 130 of said structure, when making variable speed operation portion be rocked to high speed position, conversion rod 152 is promptly swung by the speed change cable, shown in Figure 27 (A), just conversion plectane 151 is configured to the high speed position in left side.Just be connected by driving claw 155 with crank shaft 131 at this state lower frame body 148.As a result, the rotation of crank shaft 131 direct of travels just is directly passed to framework 148, and crank gear 135 is promptly with the rotational speed identical with crank shaft 131.
When variable speed operation portion was flapped toward low-speed position, conversion rod 152 was promptly swung by conversion rod 151, and shown in Figure 27 (B), conversion plectane 151 promptly is disposed at the low-speed position of central authorities.Under this state, driving claw 155 is promptly by the conversion pawl 151b of conversion plectane 151 and swing, and driving claw 155 become can not driving condition.As a result, framework 148 is connected with crank shaft 131 disengagements.So crank shaft 131 just passes to sun wheel 147 in the rotation of direct of travel via driving claw 149.When sun wheel 147 when direct of travel rotates, planetary wheel 146 is oppositely rotation and in the direct of travel revolution of slowing down just.Like this, crank gear 135 just rotates by framework 148 decelerations.
When variable speed operation portion swings to the stagnation of movement position, operate this state of maintenance by input password or lock etc.When variable speed operation portion was configured to this stagnation of movement position, conversion rod 152 was promptly swung by the conversion cable, shown in Figure 27 (c), made conversion plectane 151 be in the right lock position.Under this state, just by the conversion pawl 151b swing of conversion plectane 151, driving claw 155 becomes can not driving condition for driving claw 155.Simultaneously, engagement groove 151a cooperates with engagement groove 148a, and framework 148 is connected locking via switching plectane 151 with box portion 142.Like this, even crank arm 133a, 133b are followed into direction rotation, because crank shaft 131 is locked, crank gear 135 does not rotate.But if crank arm 133a, 133b are rotated along direction of retreat, even framework 148 is locked, driving claw 149 also is separated from sun wheel 147 and crank shaft 131 just can rotate.But the rotation of crank shaft 131 can not send crank gear to.Thereby be that impassabitity steps and pedals plate and ride bicycle under this lock-out state, so be difficult for stolen.
In addition, if give the effect of conversion plectane from Figure 27 left side, conversion plectane and framework 148 are relatively rotated in latched position with suitable acting device.But at this moment, rotation suffers restraints and sends the sound owing to relatively rotating.
Form of implementation 6
Figure 28 shows bright form of implementation 6, and it is the variation of form of implementation 3.This form of implementation 6 is identical with form of implementation 3, all be with key 181 with the 9b of variable speed operation portion in the stagnation of movement locking position.
In Figure 28, the 9b of variable speed operation portion has integrally formed main part 160b on right side brake rod 16, and the operating portion 161a that is installed on the main part 160b free to rotate.Be provided with circular display part 162a that is used to refer to shift position or stagnation of movement position and the locking part 163a that when operating portion 161a is positioned at the stagnation of movement position, is used for keeping this state among the main part 160b.
Display part 162a is supported on the main part 160b free to rotately, rotates with operating portion 161a interlock.Pointer 165a is arranged on the surface of display part 162a, be used to refer to show " 1-4 " that in main part 160b, retouched out the numeral of totally four shift position and " P " this show the literal of stagnation of movement position.By pointer 165a, can the display operation position be in four shift position and stagnation of movement position which.
Locking part 163a comprises that the cylinder locks 170a that can be rotated by key 181 is with the Lock Part 172b of cylinder locks 170a interlock moving linearly and to the right-hand helical spring 173a to Lock Part 172b effect of Figure 29 shown in Figure 29 and 30.
The bottom of helical spring 173a is connected by the bonding pad 160c that is located on the main part 160b, and front end is by the bonding pad 172d institute combination of being located on the Lock Part 172b, and gives Lock Part 172b effect in operating portion 161a one side.
On the end face of facing with main part 160b of operating portion 161a, be formed with: when operating portion 161a is adjusted to the stagnation of movement position and the right engagement groove 166a of the front end face of Lock Part 172b, and when operating portion 161a is adjusted to the shift position of 1-4 speed in the face of the shifting chute 167a of Lock Part 172b front end.The C font that engagement groove 166a can cooperate with the front end of Lock Part 172b when forming corresponding to the stagnation of movement position, shifting chute 167a then form fan-shaped corresponding to 1-4 speed shift position.The 168a of wall portion between shifting chute 167a and the engagement groove 166, the front end with Lock Part 172b under common motoring condition joins, and operates even become operating portion 161a, otherwise can not carry out from shift position to the stagnation of movement position or the retainer of operation.
In the 9b of variable speed operation portion, when key 181 is inserted among the cylinder locks 170a,, make cylindrical portion 170b also be positioned at primary importance (Figure 30 (A)) side because helical spring 173a makes Lock Part 172b stressed to operating portion 161a one side.Like this, when operating portion 161a was arranged on any one of four shift position, the front end of locking piece 172a was promptly outstanding in shifting chute 167a, and operating portion 161a then can only rotate between four shift position of 1-4 speed.In addition, when operating portion 161a was positioned at the stagnation of movement position, the front end of Lock Part 172b was projected in the engagement groove 166a, and operating portion 161a is locked in the stagnation of movement position.
Carrying out from the stagnation of movement position to shift position or during its oppositely directed operation, key 181 can inserted cylinder locks 170a, cylindrical portion 170b just turns over 90 from primary importance and spends on the second place shown in Figure 30 (B) then.As a result, Lock Part 172b just revolts the application force of helical spring 173a and retreats, and the front end of Lock Part 172b is deviate from from shifting chute 167a or engagement groove 166a.Like this, operating portion 161a just can rotate between stagnation of movement position and shift position.For this reason, for example available left-handed key 181, in that cylindrical portion 170b is turned under the former state state of the second place, when with the right hand rotating operation 161a of portion, operating portion 161a just can carry out from the stagnation of movement position to shift position or the operation opposite with it.Finished its operation at operating portion 161 after, can remove the power of left hand, by the added power of helical spring 173a Lock Part 172b is advanced, and cylindrical portion 170b just turn to primary importance from the second place.Like this, the front end of Lock Part 172b just is coupled among shifting chute 167a or the engagement groove 166a, and operating portion 161a then can only rotate or be locked in the stagnation of movement position on four shift position.
So, under common motoring condition, first key 181 extracted out from cylinder locks 170a, and when unlocking when only in stagnation of movement, locking or in beginning to travel, key 181 is inserted among the cylinder locks 170a, make cylindrical portion 170b turn to the second place from primary importance.Thus, Lock Part 172b retreats, and operating portion 161a can carry out rotating to the stagnation of movement position or in contrast to this from shift position.Like this, when operating portion 161a turns to the stagnation of movement position, just rotate with interior cable bonded assembly operating body 78, corresponding, sleeve 77 just turns to latched position PK, and the rotation of interior dress or speed-variating hub 10b promptly suffers restraints, and simultaneously hub shell 43 is just rotated and sent the sound.Thereby identical difficult generation theft accident with above-mentioned form of implementation, can prevent that bicycle is stolen.In addition because operating portion 161a just can remain in this state when in a single day being adjusted to the stagnation of movement position, unless thereby by cylinder locks 170a just Lock Part 172b retreat, otherwise there should be no return to shift position.Therefore, be difficult to the anti-joyride device 85 that is in antitheft position is separated ON operation, make robber's car become more difficult.
In addition, need not be like this in car travels because key 181 just will insert during just when locking or at latch-release among the cylinder locks 170a, so can insert simultaneously in the key holding element with key with the wheel lock that is installed in the lock under steam, thereby be difficult for making key 181 to lose.
Other form of implementation
(a) in aforementioned each form of implementation, be that anti-joyride device is located in built in type speed-variating hub, front wheel hub or the crank, but the present invention is not limited to above-mentioned fit, but anti-joyride device can be arranged in the parts that can rotate corresponding to travelling of bicycle.
(b) in aforementioned each form of implementation, transmission system is a quaternary structure, but also can comprise continuously variable unit in the transmission system that a plurality of speed change levels are arranged.
According to bicycle theft-prevention handling device of the present invention, in case selected just can keep this selection mode behind the antitheft position, thereby be difficult for untiing anti-joyride device, and the antitheft releasing operation that has parts that travel of anti-joyride device can't be carried out simply.
According to bicycle shift operating device of the present invention, when parking, car, just can make to have at least a wheel not drive or to rotate by the operation of blocking device.Like this, as long as selected just can keep this selection mode behind the lockout mechanism by locking operation device.Because once having selected lockout mechanism just can keep this state, just untiing of lockout mechanism is not easy, thereby the latch-release that can't have the lockout mechanism transmission system is simply operated.
