Abstract

A shift control apparatus for a bicycle comprises an output transmission member that moves to at least a first output position and a second output position, a position maintaining mechanism, and a release control mechanism. The position maintaining mechanism includes a position maintaining member that moves between a position maintaining position and a position release position, wherein the position maintaining position maintains the output transmission member in one of the first output position and the second output position. The position release position allows the output transmission member to move toward the other one of the first output position and the second output position. The release control mechanism includes a release member that moves between a first release member position and a second release member position. The release control mechanism moves the position maintaining member to the position release position as the release member moves from the first release member position toward the second release member position and allows the position maintaining member to return to the position maintaining position before the release member begins moving back toward the first release member position, or as the release member continues to move toward the second release member position.

In this embodiment, the three front sprockets lie next to the bottom plate: the members are coaxial with the shaft and rotate integrally. A chain 66 is engaged with a plurality of front sprockets 62 and one of a plurality of self-rotating sprockets of the wheel 54. A front shifting gear transmission: mechanism 7 moves the chain 66 from one front sprocket 62 to the other, and a rear shifting gear shifting mechanism 74 moves the chain 66 from one rotating sprocket to the other. The two operating systems are well known. In this embodiment, the variable speed gear transmission 7 is controlled by the traction and release-strips connected to the output control line 78 of the auxiliary mechanism 14, and the auxiliary mechanism 14 is connected by a Bowden type connected to the shift control device. The inner wire 8 of the control cable 82 is controlled, and the shift control device 84 is mounted to the left side of the handle 50. The rear shifting gear mechanism 74 is controlled in a conventional manner using a Bowden type control cable 86. 2 is an exploded view of the handle shank 5 〇 of the more detailed shift control device 84 and the shift control device 84 of FIG. 3 . In this embodiment, the shift control device 84 is mounted between a fixed handle 92 and a brake lever bracket 94 that generally supports the brake lever %. The shift control device 84 includes a base member (10), a clamp 106, a biasing assembly in the form of a spring 110, an intermediate member ι4, an actuating assembly 118, and a locator 122. The base member 1〇2 includes a tubular portion 126 and a flange portion 13〇. The tubular portion 126 surrounds the handle shank 5, and 86029 125916 凸缘 the flange portion 1 300 extends radially outward from the inner end of the tubular portion 126. The lost hoop 〇6 has a locking projection 134 and mounting ears 138 and 142, and the structure is mounted in a nucleated slot (not shown), wherein a locking slit is formed in the inner peripheral surface of the flange portion 13〇 on. A screw 144 extends through the opening 148 in the flange portion 130 and through the ear I 3 8 and 14 2 and locks into a nut 152 disposed in the other opening 153 of the flange portion 13 3 . In order to lock the mounting ears 138 and 142 to each other' and thereby fasten the clip 106 and fasten the base member 1〇2 to the handlebar 5〇. A general screw type of adjustable control cable coupler 1 56 is disposed on the flange portion 130 for receiving the housing 81 of the control cable 82 in a conventional manner. Radially opposed slots 160 having bearing surfaces 160a and 160b (only one of which can be seen in FIG. 3) are mounted at the junction of tubular portion 126 and flange portion 130, and a base in the form of a spring hole is biased. The assembly 1 64 is formed in the flange portion 13 〇. A spring κ 110 end 168 is mounted within the elastomeric aperture 164. The intermediate member 114 is rotatably supported on the tubular portion 126 of the base ι 2 such that the spring 110 is disposed between the intermediate member 114 and the flange portion ι3 of the base member 1〇2. Radially opposed projections or stops 172 forming support surfaces 172a and 172b (which may only be viewed in FIG. 3) extend axially from the inner end of intermediate member 114 and form a radially opposing center of one of bearing surfaces 188a and 188b. Member protrusions or stops 188 extend radially outward from the peripheral surface 184 of the intermediate member 114. The spring 11 end 192 is mounted in a spring opening 194 (which functions as a biasing engagement assembly of the same intermediate member) and the spring opening 194 is formed in one of the stops 188 of the forward biasing intermediate member U4. As a result, the bearing surface of the stopper 172 is ported to engage the bearing surface 16A (which functions as the same base member stopper) to restrict the rotation of the intermediate member 114 relative to the base member 1〇2. 86029 -10- 1259160 The actuation assembly 118 can be rotatably supported by the intermediate member 114. As described above, the intermediate member 114 can be rotatably supported by the tubular portion 126 of the base member 102. Thus, the actuator assembly 118 rotates coaxially along the intermediate member 114, the tubular portion 126 of the base member 1A2, and the handle 50. The actuation assembly 118 includes a tubular member 2, a first and second finger projections or cups 204 and 208 extending radially outward from the tubular member 200, and a transmission control member coupling assembly in the form of an opening 212. A cable end bead is attached to the end of the inner wire 80 so that the inner wire 8 turns integrally with the actuation assembly 118 and forms radially symmetric slots 216 of the bearing surfaces 216 & In the assembled state, the intermediate member stop 188 is seated in the corresponding slot 2 16 between the bearing faces 2 1 6 a and 2 1 6 b so that the bearing faces 2 16a and 2 16b function as an actuating member Stopper. In this embodiment, since a biasing assembly is disposed in the auxiliary device 14, the inner wire 80 of the control cable 82 is under tension. Thus, the actuation assembly 118 is biased in a reverse direction such that the bearing surface 18 8 a of the intermediate member stop 18 8 engages the bearing surface 2 16 a to limit the actuation assembly 118 relative to the intermediate member 114 and the base member The rotation of I 0 2 . The positioner 122 is mounted along the outer end of the base member 1〇2 tubular member 126. The locating device 122 includes four slots 220 that are evenly formed on one side surface 224 for engaging four locking tabs 228 that are detachable from the outer end of the tubular member 126 of the base member 1〇2 Extending radially outward. Thus, the positioner m axially securely positions the actuation assembly II 8 and the intermediate member 114 on the base member 丨〇2. 4(A)-4(C) schematically illustrate the operation of the shift control device 84. Figure 4 (A) shows the actuating assembly 11 8 in the neutral position of the inconsistent moving assembly. In this position, the spring 110 biases the intermediate member U 4 in the forward direction (to the right in FIG. 4(A)) so as to stop the bearing surface 172a of the 86029 -11 - 1259160 stopper 172 on the base member 1〇2. In contact with the bearing surface 160a of the slot i6, a biasing assembly (spring), indicated by reference numeral 232 in the auxiliary mechanism 14, biases the actuator assembly 118 counter-rotatingly so that the bearing surface 216a of the slot 216 and the intermediate member The stopper 188 is in contact with the bearing surface 188a. Thus, the bearing faces 160a 172a, 188a and 216a (and to some extent like the springs 11A and 232) function as a neutral positioning component. Since the inner rib is directly connected to the actuating member, the inner portion 80 is also located at a mutual position in a transmission control member. k Figure 4 (A) does not position the actuation assembly} 丨 8 to rotate in the forward direction to counteract the biasing force of the biasing assembly 232 in the auxiliary assembly 14 and to cause the bearing surface 216b on the actuation assembly 2168 The support surface on the intermediate member stopper 188 shown in Fig. 4(B) is in contact with each other. The intermediate member U4 is now stationary. In Fig. 4(B), the actuating assembly 11 8 is located at the deceleration shift position of the actuating assembly, and the inner wire (10) is pulled into the deceleration shift position of a transmission te member. k The position shown in Fig. 4(A) reverses the actuating element 丨丨8, causing the intermediate member 1143⁄4 to rotate (toward the left side of Fig. 4 ((:)) to counteract the biasing force of the spring no, because the bearing surface The bearing surface of the intermediate member stop 188 is "contacted and the κ 110 is fully coupled between the actuating assembly 丨丨 8 and the base member 丨〇 2. As a result, the actuating assembly 118 is located in the accelerated shift position of the actuating assembly.

Rotating to the acceleration shift position so that the inner wire 80 is released by the actuating assembly 118. This causes the wire coupling member 302 to rotate in the forward direction in Fig. 6, and this movement is transmitted through the input link 3〇6 and the control panel 5 1 8 Connected, thereby causing the control panel 5 1 8 to rotate in the forward direction to the accelerated shift position as shown in Fig. 16 (B). The forward rotation of the control panel 5 18 causes the drive control pawl 5 3 〇 to slide down to The inclined surface 606c of the cam protrusion 606 is reversely rotated to the position shown in Fig. 16(b).

Because the drive pawl is driven 53 8 is no longer in contact with the bearing surface 578, the motion transmission member 498 is rotated in the forward direction until the drive control pawl 538 is in contact with the bearing surface 588, and the motion transmission member 498 is in the "access" position as shown in Figure 16 (B). . No longer subjected to the clamping of the drive teeth 694 on the positioning ratchet 458, the motion transmitting jaws 5〇6 are reversely rotated, and V remains on the peripheral surface 678 of the positioning ratchets 458. The forward movement of the motion transmission member 498 is transmitted to the support plate 406 in the positioning ampere panel 402 and the rotating member engaging unit 258, so that the rotating member engaging member 394 is pivoted to the position shown in Fig. 9(B). When the driving member 290 on the crank 266 is engaged with the rotating member engaging member 394, and the positioning unit interface panel 402 and the support plate 406 are pivoted to 86029 -19- 1259160 shown in FIG. 9(c), the motion of the temple 4 will be transmitted to the motion. Transmission member 498. The motion transmitting claw 506: the ratchet driving surface 506d is coupled to the driving teeth 094 on the positioning ratchet 458 and is rotated from the switching ratchet 458 and the rotating member 454, thereby winding the output control 1, 'spring 78. During this period, the positioning teeth 682 are pressed against the claws 475 ^ of the positioning claws 474, /, and the rotating positioning claws 4 7 4 until the claws 4 7 5 are separated from the tips 2 of the positioning gums 8 2 , the positioning claws 474 are reversed. Rotate so that the claws 475 are located between the positioning teeth 682 and 686 as shown in Figure 16(c). When the driving member 29A on the field crank 266 is separated from the rotating member engaging member, the clamping unit interface panel 4〇2 and the supporting plate 4〇6 are turned rearward toward the position shown in FIG. 9(A), and the movement is performed. Transfer to the motion transmission member 498. The motion drive pawl 506 is disengaged from the drive teeth 694 on the clamp ratchet 458, and the positioning ratchet rim and the diverter member 454 rotate in unison according to the biasing force of the spring 456 until only the teeth 682 abut the claws 475. At this time, the front shifting gear transmission mechanism 7 is aligned with the intermediate diameter front sprocket. However, it is assumed that the swim code has not rotated the actuation assembly 118 back to the neutral position at this time. In this case, the control panel 518 will still be in the accelerated shift position, with the drive control pawl 538 resting on the upper surface 614&amp; of the cam lobe 614. In this position, the drive control pawl 538 will not engage the bearing surface 578, thereby stopping the rotation of the motion transmitting member 498. Thus, without returning to the open position shown in Fig. 16(A), the motion transmitting member 498 will continue to rotate to the access position shown in Fig. 16(B), and the rotating member engaging member 394 will return to Fig. 9(B). The illustrated rotational member engagement position, as well as another shifting action will occur. Such an operation may be achieved in some applications and is within the scope of the invention. In any event, in this embodiment, the drive control pawl 530 is provided to avoid such repeated shifting. More particularly, 86029 -20- 1259160, as described above, in the reverse rotation, the drive control pawl 5 3 〇 now contacts the bearing surface 570 on the motion transmission member 498 at this position, and temporarily stops the further rotation of the motion transmission member 498 for movement. Transmission member 498 is in the position shown in Figure 16(d). Thus, the drive control pawl 530 and the cam lobe 606 include a drive control mechanism for disabling the motion transmission member when the motion transmission mechanism transmits motion from the rotary member a member 394 to the rotary member 454. 498 rotates back to the access position. When the travel code returns the actuation assembly 丨丨 8 to the neutral position, the control panel 5 ι 8 also rotates back to the neutral position shown in Figure 16(E). After that, the drive control pawl 530 slides up to the ramp 6〇6〇 on the cam lobe 6〇6 and rotates in the forward direction until the control pawl 530 is separated from the bearing surface 57〇 on the motion transmission member 498, and is controlled. The tip end of the claw 530 stays on the upper surface 6〇6a of the cam projection 6〇6. Further, the drive control pawl 538 is slid downward to the inclined surface 61 4b of the cam projection 614, and is reversely rotated to drive the tip end of the control pawl 538 into contact with the bearing surface 578 on the motion transmission member 498 shown in Fig. 16(E). The motion transmission member 498 is now in the open position as shown initially in Fig. 16(A), but the positioning ratchet 458 and the rotating member 454 in this position are aligned with the intermediate diameter front sprocket of the front shifting gear transmission 7A. The operation from the intermediate diameter front sprocket to the large diameter front sprocket is the same. 17(A)-(F) are diagrams illustrating the operation of the positioning unit 254 in the deceleration shift direction. Some components in a transparent graphical representation will help to understand the component operations that play an important role in this deceleration shift operation. It is assumed that the position of the rotating member 454 is such that the front shifting gear transmission 7 is aligned with the intermediate diameter front sprocket (the position shown in FIG. 16(E)), and it is desirable to drive the front shifting gear 86029 -21 - 1259160 mechanism. 70 Move to the small diameter sprocket. Therefore, in the position shown in Fig. 7 (Α), the tip end of the drive control pawl 530 is again supported by the upper surface 606a of the cam projection 606' and the tip end of the drive control pawl 538 is located at the cam projection 6 1 the bevel 6 1 The bottom of 0c, such that drive control pawl 538 is in contact with bearing surface 578 on motion transmission member 498. The motion transmitting claw 5 〇 6 stays on the upper surface of the driving tooth 689 on the positioning ratchet 4 5 8 . A complete outer cam plate 494 having a circular and elongated isosceles triangle includes an axially extending locating tab 495 that abuts the side surface 487' of the release plate 486 to grip the Figure 17 (A) Cam plate 494 in position. The run code then rotates the actuating assembly 118 forward (as shown in Figure 3) to the position of the deceleration shift so that the inner wire 80 is pulled up by the actuating assembly U8. This causes the wire coupling member 302 to rotate counter-rotating as shown in Fig. 6, and this motion is transmitted to the control board 518 through the input link 306 to reverse the control plate 5 丨 8 as shown in Fig. 17(B). The reverse rotation of the control panel 518 will cause the drive control pawl 53 to slide down to the ramp 606b of the cam lobe 606 and rotate in the opposite direction. At the same time, the drive control pawl 538 slides on the inclined surface 61〇c of the cam projection 610 and rotates clockwise until the drive control pawl 538 is separated from the support surface 578 on the motion transmission member 498 and stays on the cam projection 610. Surface 61〇a. Because the drive control claw

The shifting pawl 538 is no longer in contact with the bearing surface 578, the motion transmitting member 498 is rotated in the forward direction until the drive control pawl 538 is in contact with the bearing surface 588, and the motion transmitting member is located at the access position shown in Figure 17(B). At the same time, the motion transmission member is swung forward by the transfer surface 61 of the cam projection 618, and the mode shifting claw engagement and the movement of the motion motion transmission member 498 in the position shown in the temporary clamping diagram _) are transmitted. The positioning unit dielectric panel 402 and the support plate 4〇6 in the rotating member 86029-22-1259160 unit 258 are rotated so that the rotating member engaging member 394 is pivoted to the position of FIG. 9(B). When the drive member 290 on the crank 266 is coupled to the rotating member engaging member 394 and the foot K unit media panel 402 and the support plate 406 are pivoted to the position shown in FIG. 9(C), the motion is again transmitted to the motion transmitting member. 498, but at this time the release plate driving surface 5 〇 6 e of the motion transmission claw 506 engages with the support surface 487 on the release plate 486 (which is now in a first release member position), and the release plate 486 is Fig. 17(C) is rotated π in the reverse direction. Thus, the force of the motion transmission member 49 8 is like the release drive member for releasing the plate 4 § 6 in this mode. When the release plate 486 is rotated, the base surface 496 of the cam plate 494 is in contact with the core cam roller 478 connected to the positioning claw 474, and the positioning claw 474 is rotated in the forward direction. When the large end of the pawl (four) 475 exits the tip end of the foot tooth 682, the positioning ratchet and rotating member 454 rotates in accordance with the biasing force of the spring 456 until the positioning tooth abuts the claw 476 to avoid positioning the ratchet 458 and the rotating member 454. Uncontrolled rotation. When the field release plate is displaced, the cam roller 478 reaches the circular shape of the cam plate 494 or the cam protrusion 497 when the second release member is rotated backward toward a second release member position (the end of the release plate 4/6 movement range). Thereby, the cam plate 494 is reversed, and then the I, the respective positioning claws 474 are reversely rotated, so that the claws 476, 1 and the foot 闯 680 are used to retract the positioning ratchet 458 and the rotating member to continue. u, Α τ until the rotating member 454 is positioned so that the front shifting gear transmission 70 is aligned with the smaller diameter sprocket. The system operates as known in the art, i.e., using a positioning pawl and positioning ratchet to perform the shifting operation, the claw 476 will remain engaged with the positioning tooth 686, straight 86029 -23 - 1259160 to the release plate 486 reverse ( That is, reverse rotation) to complete the replacement operation. It is not necessary to have the shift control mechanism as constructed in accordance with the present invention because the rotatable cam plate 494 allows the positioning pawl 474 to directly shift into a shifting operation when the release plate 486 is still rotated in the reverse direction. Thus, the release plate biasing cam plate 494 can be viewed as a release control mechanism that moves the positioning pawl 474 to the position release position as the release plate 486 moves toward the second release member position, and when the release plate 486 continues toward the position When the position of the second release member moves, the allowable positioning claw ο# returns to the position maintaining position. Another advantageous feature of the preferred embodiment is that the release plate 486 can be allowed to be reversed even if the motion transmission member 498 is still rotated in the reverse direction. As a preferred embodiment, when the motion transmission member 498 is in the position shown in Figs. 17 (〇 and 18 (8), the deceleration shift control surface 5〇6c of the motion transmission claw 506 starts as shown in Fig. 18(A). The jaw control surface 66 of the intermediate plate 466 is in contact with each other. Further rotation of the motion transmission member 498 causes the motion transmission pawl 506 to rotate counter-rotating as shown in Figures 17(D) and 18(B), which in turn causes the motion transmission pawl 5〇6 to The release plate 486 is disengaged. The mode change pawl 514 is also separated from the mode change pawl contact surface 506f of the motion drive pawl 506 and stays on the mode change pawl contact surface 5〇6 §. Thus the 'release plate 486 allows direct return to FIG. 17 ( D) The position shown, even if the motion transmission member 498 is still in the reverse position shown in Fig. 17(D). When the drive member 290 on the crank 266 is separated from the rotary member engagement member 394, the positioning unit interface panel 402 and the support plate 4〇6 is again swiveled toward the position of Figure 9(a), and this motion is transmitted to the motion transmission member 498. Again, it is assumed that the actuation assembly 丨丨8 is not rotated back to the neutral position on the game code. In such a situation The control board 5 1 8 is still in the deceleration shift position And the drive control pawl 5 3 8 86029 -24- Ϊ 259160 is left on the upper surface 610a of the cam protrusion 610, and the drive control pawl 530 is in contact with the bearing surface 570 on the motion transmission member 498 so that the motion transmission member 498 is located in FIG. (E) The pause position shown. When the travel code returns the actuation assembly 11 8 to the neutral position, the control panel 5 1 8 also rotates back to the neutral position shown in Figure 17 (F). At this time, the drive control pawl 530 slides up to the slope 606b of the cam lobe 606, and rotates in the forward direction until the drive control pawl 530 is separated from the support surface 570 on the motion transmission member 498' and the tip end of the drive control pawl 530 stays on the cam lobe The upper surface 606a of the 606. At the same time, the 'drive control claw 539 slides down to the upper surface 61〇c of the cam projection 6 1 , and rotates counterclockwise to drive the tip end of the control pawl 538 and the motion transmission member shown in the drawing. The bearing surface 578 on 498 is in contact. The motion transmission member 498 is now in the open position as shown in the original Figure io 7 (Α), and the positioning ratchet 458 and the rotating member 454 at this position cause the front shifting gear transmission 7 to be small. The diameter front sprocket is aligned. The operation of the large diameter front sprocket shifting to the medium diameter front sprocket is the same. In any event, in this case, the positioning ratchet 458 will be positioned in the initial position such that the claw 475 abuts the positioning tooth 686. When the positioning pawl 474 When the pressure from the cam plate 494 is rotated in the forward direction, the claws 475 are moved away from the positioning teeth 686, and the positioning ratchets 458 are rotated in reverse until the positioning teeth 690 are in contact with the claws 476. When the positioning claws 474 follow the cam projections of the skill wheel 494 When the 497 reaches the cam roller 478 and rotates in the reverse direction, the claws 47 5 enter the space between the positioning teeth 682 and 686, and the claws 476 release the foot teeth 690 so that the positioning ratchet 458 and the rotating member 454 rotate in the forward direction until the foot position The teeth 682 are in contact with the claws 475, thereby maintaining the positioning ratchet 458 and the rotatable member 454 in the position shown in Fig. 17(A). 86029 - 25 - 1259160 While various embodiments of the invention have been described above, further modifications may be made without departing from the spirit and scope of the invention. For example, while the drive actuators 53 and 53 of the separate operation are provided in the preferred embodiment, the embodiment shown in Figures 19(A) and 19(B) represents a single drive having claws 704 and 708. The pawl 700 is controlled to contact the bearing surface 578 on the motion transmitting member 498 when the motion transmitting member 498 is in the home position shown in Fig. 19(A). When the motion transmission member 498 is rotated to the off position in the forward direction, and the control plate 486 is not rotated to the neutral position as shown in Fig. 19(B), the claws 7〇8 and the support surface 57 on the motion transmission member 498〇 contact. Although a cam plate 494 is used to technicalize the pawl 474 in the deceleration shifting operation of the embodiment, Fig. 20 shows an embodiment in which a cam gear 75 〇 controls the operation of the positioning pawl 474. In this embodiment, the cam gear 75 is mounted on the positioning ratchet 4 58 in the same axis and in a rotational manner. The cam gear 75 5 includes a plurality of circumferentially disposed cam teeth 754 and a plurality of circumferentially disposed cam drive teeth 758. A cam drive pawl 762 is pivotally mounted to a release plate 486 via a pivot 766 and is biased in a reverse bias by a spring 77. When the release plate 486 is reversely rotated during the deceleration shifting operation, the cam driving pawl 762 is in contact with one of the plurality of cam driving teeth 758 and reversely rotates the cam gear 75A. One of the plurality of cam teeth 754 is pressed against the cam roller 478, and the positioning claw 474 is reversely rotated in the same manner as the preferred embodiment. When the cam teeth 754 pass the cam roller 478, the positioning claws 474 are reversely rotated to complete the operation of the deceleration shift. When the release plate 486' is rotated in the forward direction, the cam driving pawl 762 is separated from the corresponding cam driving tooth 7 58. Figure 2 is a detailed view of an embodiment of a shift control device 80, and 86029 -26- 1259160 the shift control device _ can be used together with the auxiliary mechanism 14, and the system is replaced by Set an exploded view of 8〇〇. In this case, the shift control device # is mounted on the operating handle 5〇 inwardly adjacent to the brake lever bracket 94. The change control garment 80G includes a mounting unit such as a base member 816 that includes an integrally formed central hoop (10) whereby the private shift control device 8 is fixed to the steering in a general manner. Handle 5 〇. A screw type, cable 33 combiner 828 locks the base member 816 in a general manner to receive the housing 8 of the control cable 82. Typically, the control cable, the inner wire 80 of the table 82 is released by applying a finger contact portion 8〇2 of a shift control member such as the actuating member 8 (10), and the inner wire (9) of the control cable 82 is applied by The finger contact portion 806, such as the shifting control member of the actuating member 808, is pulled up and the gear train now selected is indicated by a gear indicator unit 812. An actuating member bracket 836 having side walls 844 and 848 is mounted to the underside of the base member 816 by a screw 84. A bracket 852, an actuating guide member 856, a bracket 860, a biasing support plate 864, and a bracket 868 are all mounted to the side wall 8 through a screw 872 (only one such screw is shown in Fig. 22). The actuating member 804 includes an elongated portion 876 extending from the finger contact portion 8〇2 and surrounding the actuation guide member 856 with an opening 880 for actuating the member 804 in a direction that substantially manipulates the handle 50, A first shift control position such as the home position shown in Fig. 21 and a younger control position such as the innermost compression position shown in Fig. 24(D) are moved between the control positions. A claw support base § 8 4 extends laterally from the end of an elongated portion 876, and a claw shaft 8 8 8 extends upwardly from the pawl support base 8 8 4 . A spring 8 9 2 is coupled between a biasing support plate 86029 -27 - 1259160 4 (the lug 896 and the pawl support base m) for biasing the actuating member 8〇4 toward the home position. A shift control drive member such as a pawl including a shift control bearing surface (e.g., tooth) 902 can be rotatably supported by the pawl shaft 888 and can utilize a claw spring 9 〇 4 such as mounted between the pawl support base 884 and the pawl 9 The drive member biasing mechanism is biased in the forward direction. The claw 9 is fixed to the claw support shaft 888 by a clip 9〇8 and a loop 912. Similarly, a bracket 920, an actuating guide member 924, a bracket 928, a biasing support plate 932, and a bracket 936 are mounted to the side wall through a screw 94 (only one such screw # is shown in FIG. 22). 848. The actuating member 8A includes an elongated portion 944 extending from the finger contact portion 806 and surrounds the actuation guide member 924 with an opening 948 for actuating the member 8A to substantially vertically manipulate the handle 50. Moving between a first shift control position, such as the home position shown in FIG. 21, and a second shift control position, one of the innermost compression positions. A claw support base 952 extends laterally from the end of an elongated portion 944, and a claw shaft 956 extends upward from the claw support base 952. A spring 960 is coupled between a lug 964 and a pawl support base 952 on the biasing support plate 932 for biasing the actuating member 80 toward the home position. A shift control drive member such as a pawl 9 6 8 including a shift control bearing surface (e.g., tooth) 97 can be rotatably supported by the pawl shaft 956 and can be utilized, for example, between the pawl support base 952 and the pawl 968. The drive member biasing mechanism of the pawl spring 972 is biased in the forward direction. The pawl 968 is secured to the pawl support shaft 956 by a clip 976 and a loop 980. A bolt 9 8 4 extends through an opening 9 8 8 in a base member 8 16 and through an opening 992 in an actuator member bracket 836 such that the head 996 of the bolt 984 is flush with the upper surface of the base member 816. The bolt 984 is further mounted through a 86029 -28-1259160 in a sleeve 1 诸如 in the center opening ι (10) of the conductive control element such as the winding element 1008, through the opening 1 〇 12 of the release plate 1016, through the gasket and 1028, and The spacer 1 〇 24, through a central opening of a biasing plate 1 〇 36, through a spacer 1040 and a gasket 1044, through the interior of a radial coil spring 1 〇 48, through a central opening 1052 of a biasing plate 1056, through a The washers are 1〇6〇 and extend through the central opening 1〇64 of a biasing stopper plate 1〇68. These components are attached to the thread check 9 8 4 by a nut 〇 72 that is locked to the threaded end 1 〇 74 of the bolt 984. The winding element 1008 includes a transmission control drive member such as a conductive control bearing surface 1〇76 and 1〇8〇, a downwardly extending biasing engagement member 112〇, and a winding slit for winding and unloading the inner wire 80 of the control cable 82.丨〗 22. The release plate 丨〇 j 6 is secured to the base member 816 by a screw 1090 and includes release members such as cam surfaces 1084 and 1088. The function of the previous components is explained below. The biasing plate 1 0 36 includes a radially outwardly extending stopper 丨丨丨6 and a radially outwardly extending winding member biasing member 1124. Similarly, the biasing plate 1 〇 56 includes a radially outwardly extending stopper 11 〇 8 and a radially outwardly extending winding member biasing member 1128. One end 1〇92 of the spring 1〇48 is inserted into one of the plurality of circumferential openings 1096 formed in the biasing plate 1036, and the other end of the spring 1048 is engaged with the stopper 11〇8 of the biasing plate 1056. As a result, the biasing plate 1036 is biased in the forward direction so that the stopper 1116 is pressed upwardly by the biasing stopper plate ;"; the stopper column 1112, and the biasing plate 1 〇 56 are reversely biased so as to stop the 叩 11 〇 8 is pressed against the stopper column 2. The biasing engagement member 1120 of the winding member 丨 (9) 8 is sandwiched in a first (e.g., primary or intermediate) transmission control position between the winding member biasing members 1124 and 1128. When the winding element 丨〇〇8 is rotated toward the second (eg, releasing the line) transmission control position, the spring 1048 and the biasing plate 1056 function as the same transmission control element biasing mechanism. If the winding element 1 0 0 8 is reverse biased back to the first transmission control position, likewise, when the winding element 1008 is rotated counterclockwise toward a third (eg, tensioning the line) transmission control position, then the spring 1〇48 And the biasing plate 1〇36 functions as another transmission control element biasing mechanism to positively bias the winding element 丨〇〇8 back to the first transmission control position. The gear indicating unit 812 includes a transparent window 1154. Cover π 5〇 (Fig. 21), an indicator (1), a claw support plate 1162, a motion transmission member 1166, indicator drive elements such as the pawls 70 and 1174, and a biasing spring 1178. The indicator 1158 is permeable to a screw 1182 and a washer 1186 is mounted to the head 996 of the bolt 984. More clearly, as shown in Figure 25(A), the indicator 丨丨 "includes indicator drive elements such as claws 1158a, 1158b, 1158c, and 1158d. The screw 1182 also mounts the pawl support plate 1162 at the head 996 of the bolt 984, and the pawl support plate 1162 is non-rotatably fixed to the base member 816 according to the lug 1190 on the pawl support plate 1162, and the pawl support plate 1162 The lug 11 turns into engagement with the lug 1194 on the base member 816. The claw support plate 1162 includes a claw separating surface 11 62a, the function of which will be explained below.

The motion transmission member U66 is coupled to the winding element 1〇〇8' by a pair of tabs 1198 and the pair of tabs 1198 are engaged with the opening 1200 formed in the winding element 1〇〇8 to move the transmission member 1166 along with the winding element 1〇〇8 moves as a unit. The motion transmission member 1166 also includes a pawl shaft 12〇4' that pivotably supports the claws ΐ7Π1 so that the jaws are movable between an indicator drive member engagement position and an indicator drive member separation position. The end KM 86029 -30- 1259160 of the spring 丨 178 engages the jaw U7 且 and functions as a biasing mechanism that biases the jaw 1 〇 toward its corresponding indicator drive member engagement position. Similarly, the spring 1178 A ride 1234 engages the pawl 1174 and functions as a biasing mechanism that biases the pawl i toward its corresponding finger drive member engagement position. The pawl 117Mlm and the spring 1178 are secured to the pawl shaft 12〇4 by a clip 12〇8. 23(A)-23(B) and 24(bucket 24(1)) are illustrated when the actuating member 8〇4 is moved from the “first shift control position” shown in FIGS. 23(A) and 24(A). The operation diagram of the shift control device 8〇〇 (viewed from the bottom and rotated by 18〇) to the position of the π-key shift control position of Fig. (9). The finger contact portion of the actuating member _8〇2 When initially depressed, the claws 902 move along the cam surface 1〇84, and due to the biasing force of the spring 904 and the shape of the cam surface 1〇84, the claws 9〇〇 are reversely rotated until the claws 902 and FIG. 24(B) The transmission control Z bearing surface 1076 of the illustrated winding element 1 接合 8 is engaged (eg, contacted). Further pressing the finger contact portion 8 〇 2 will result in the winding element 1008 is reversely rotated to release the inner wire (10) shown in Fig. 24(c), and the auxiliary mechanism 14 is operated as described above. Meanwhile, the biasing engagement member ι2 is pressed against the biasing plate 1〇56 shown in Fig. 23(B). The winding member biases the member 1128 and reverses the biasing plate 1056 to counteract the biasing force of the spring 1 〇 48. Due to the shape of the cam surface 1084, further depression of the finger contact portion 8 〇 2 will cause the claw 900 to steer Rotate until the claw 9〇2 is separated from the transmission control bearing surface 1〇76 of the winding member 1008 shown in Fig. 24(D). When this occurs, the winding member 1〇〇8 and the biasing force due to the biasing force of the spring 1048 The pressure plate 1〇56 is reversely rotated back to the position shown in Figures 23(A) and 24(A). The separation of the claw teeth 902 from the transmission control bearing surface 1076 also produces a "click" at the position of the finger contact member 8〇2, Or the feeling of jamming, thereby notifying the swim code, the finger contact member 802 can be released. 86029 - 31 - Ϊ 259160 When the finger contact members 8〇6 of the actuating member 808 are depressed as shown in Fig. 23(c), the gamma block control device 800 operates in the same manner. In this case, the claw 97 〇 = the winding member 1008; the transmission control bearing surface 1 〇 8 〇 is engaged, the winding member 1 〇〇 8 is rotated in the direction of the pulling direction, and the auxiliary mechanism 14 is thereby operated. At the same time, the biasing engagement member 20 is pressed against the wire member biasing member 1124 of the biasing plate 1〇36 shown in FIG. 23(c), and the biasing plate 1〇36 is rotated in the forward direction to offset the biasing force of the spring 1048. the amount. Due to the shape of the cam surface 1 〇 88, the stepwise pressing of the finger contact portion 806 will cause the pawl 968 to rotate in the reverse direction until the pawl gear 97 〇 = the drive control bearing surface 1 〇 88 of the winding member 1008 is disengaged. When this occurs, the winding member 1〇〇8 and the biasing plate Μ% are reversely rotated back to the position shown in Fig. 23(A) due to the biasing force of the spring 1〇48. The separation of the claws 97 from the transmission control bearing surface ι 88 produces an identical ''Kata,' or stuck sensation at the position of the finger contact member 806, thereby notifying the travel code, the finger contact member 8 〇6 Can be released. When the shift control device 800 is operated in the pull direction (from the top), the operation of the indicator unit 812 is as shown in Figs. 25(A)-25(I). Figure 25 (a) shows the indicator 1158 in an original position. At this time, the winding member 1〇〇8 is located in the first transmission control position, and the claws 1170 and 1174 are supported by the claw separating surface n62a. Since the finger-like contact surface 8〇6 of the actuating member 808 is depressed and the winding member 1 008 is rotated in the reverse direction, the motion transmitting member 1166 moves the claws 117A and 1174 to the position shown in FIG. 25(B) so that the claw 1174 Contact with the claws n5Sa. Further rotation of the winding member 1 008 will cause the pawl 174 to press against the pawl 1158 & and rotate the indicator 1158 to the position shown in Figure 25(C). When the claws 97 〇 are separated from the transmission control bearing surface 1 〇 8 且 and the winding element 丨〇〇 8 is rotated toward the first transmission control position, the motion transmission member 1166 hooks the claw 1174 with the claws 86029 - 32 - 1259160 1158a Separated, and the pawls 70 and 1174 are rotated to the position shown in Fig. 25(D), wherein the claws 1170 and 1174 are separated by the claws! 162a support. Thus, even if the winding element 1 〇〇 8 has been rotated back to its original position, the indicator 1158 is transferred to the new selection gear. Since the finger-shaped contact surface 8〇6 of the actuating member 8〇8 is depressed for the first time, when the winding element 1 008 is rotated in the reverse direction, the motion transmission member 丨丨 “moves the claws 117〇 and 1174 to FIG. 25(E) The position shown is such that the pawl 1174 is in contact with the pawl 115. Further rotation of the take-up element 1008 will cause the pawl 1174 to press against the pawl 1158b and rotate the indicator 1158 to the position shown in Figure 25 (when the pawl 970 When the transmission control bearing surface 1〇8〇 is separated and the winding member (10) is rotated toward the first transmission control position, the motion transmission member 166 separates the claw 11 74 from the claw 1158b, and the claws 1170 and 1174 rotate to FIG. 25. (〇) shows the position in which the claws 1170 and 1174 are again supported by the claw support member U62a, and an indicator 1158 is transferred to the final gear in series. In this case, the auxiliary mechanism 14 accommodates three front gears. If the run code ignores that the shift gear drive is already in the final gear and the finger contact member 806 is depressed again, the take-up element 1008 is again rotated in reverse, and the motion transmission member 1166 moves the jaws 1170 and 1174 to that shown in Figure 25(H). Position. However, this No, any claws are engaged. As a result, the indicator 1158 remains in the same position. The take-up element 1008 then rotates back to the first transmission control position, and the jaws 1170 and 1174 are again supported on the jaw separation surface 1162 &amp; Or reducing the number of teeth to accommodate more or less gears as needed. When the shift control device 800 is operating in the opposite direction (release of the line), the operation of the indicator unit 812 is as shown in Figure 26(A)-26( I) is shown in Fig. 26. (a) shows that the indicator 1158 is in the same position as shown in Fig. 25(H). That is, the winding member 1 008 is located at the first transmission control position, and the claw 117A and 1174 are supported by the claw separating surface 1162a. Since the finger contact surface 8〇2 of the actuating member 8〇4 is depressed and the winding element 1 008 rotates in the forward direction, the moving transmission member 丨丨66 will claw 7〇 and 1174 move to the position shown in Fig. 26(B) so that the jaws 7〇 are in contact with the claws} l58d. Further rotation of the winding element 1 0 0 8 will cause the jaws 7 to be pressed against the claws 1158d. Up, and rotate the indicator 1158 to the position shown in Figure 26 (C). When the claws 9 〇 2 and pass When the control bearing surface 1076 is disengaged and the winding element 1〇〇8 is rotated in the reverse direction toward the first transmission control position, the motion transmission member 1166 separates the claw ΐ7ΐ from the claw 1158d, and the claws 1170 and 1174 rotate back to FIG. 26(D). The position shown, wherein the jaws 1170 and 1174 are supported by the jaw separating surface 116. Since the finger contact surface 8〇2 of the actuation member 8〇4 is depressed a second time, while the winding element 1008 is rotated in the forward direction The motion transmission member 1166 moves the pawl and 1174 to the position shown in Fig. 26(E) so that the claw 117 is in contact with the claw 1158. Further rotation of the take-up element 1008 will cause the pawl 117 to press against the pawl 1158c and rotate the indicator 1158 to the position shown in Figure 26 (]. When the claw 902 is separated from the transmission control bearing surface 1〇8〇 and the winding element 1〇〇8 is rotated in the reverse direction toward the first transmission control position, the motion transmission member 166 separates the claw 11 70 from the claw 1158c, and the claw 1170 and 1174 is rotated to the position shown in Fig. 26 (〇), in which the claws 1170 and 1174 are again supported by the claw separating surface U62a, and a finger 11 5 8 is swung to its original position. Again, if the run code ignores that the shifting gear mechanism is already in the final gear and the finger contact member 8〇2 is depressed again, the winding element 1〇〇8 is again rotated in the forward direction, and the motion transmitting member 1166 clamps the pawl 117 and 1174. Move to the position shown in Figure 26 ((1) 86029 -34- 1259160. Because it does not pull people π", shake the time-site rhyme, the indicator 1158 is maintained at the opposite position, and the winding element; 1 〇0 dry fairy 80,000 turns back to the first drive pawl 1170 and 1174 are again cut on the jaw separation surface U62a. The various teachings disclosed may be applied in further embodiments. For example, Figure 27(A) 27 (H^ is different) The operation of the shift lever mechanism 1 300 of some configurations and the κ release mechanism of Figs. 17(4) 17(F) can be combined. The shift lever mechanism 1 _: a bracket and/or is disposed in the - housing. However, it is only easy The structure of this copulation is shown in the figure. ' Figure 27 (A) shows the 'changing mast mechanism 13 (10) package m ratcheting 4 clamping member, - clamping maintaining member 1332, - shift lever (1) 0 form Release member, and cam member in the form of a cam plate 1324. Positioning ratchet 1304 with - rotating member (not The rotating member 454 shown in Fig. 1() is coupled to an integrally coaxial rotating axle 1333, and includes positioning teeth 1308^312 and 1316. The positioning ratchet 13〇4 and its accompanying rotating member utilize - The return magazine (not shown, but similar to the spring 456 shown in Figure 1) is biased in the forward direction. The positioning maintaining member 1332 has the form of a positioning claw supported by a claw shaft 1334 for maintaining a position (e.g., Figure 27 (A) shows a rotation between a position release position (e.g., as shown in Figure 27 (D)). The positioning claw 1332 has clamping teeth 1336 and 1340, and a pivot 1342 mounting position positioning tooth 134 〇, and a cam follower in the form of a cam roller 1344 is rotatably supported by a pivot shaft 1342. A claw spring (not shown) is provided for biasing the positioning pawl 1332 toward the position to maintain the position. The shift lever 132 ( The shifting mechanism is typically operatively coupled to the wheel axle 丨3 3 3 and includes a pivot 1328 that supports the cam plate 1 324. As in the first embodiment, the cam plate 1324 has 86029 -35 - 1259160 Finished with a squat and lengthened isosceles Outward @.一弹菩 (not shown to forward bias the cam plate 1324, such that the cam plate 1 324 includes a radially extending foot tab 1350, thereby abutting the side surface of the shift lever 132 The cam plate 1324 at the position shown in Fig. 27(A) is clamped. When the travel code reversely rotates the shift lever 1320 from the original or first release member position shown in Fig. 27 (4), the bottom surface (10) of the cam plate 1324 starts with the figure η (8). The cam light 1344 is in contact. The advance rotation of the shift lever 1320 causes the cam plate 1324 to be pressed against the camleon 1344, and then the camleon (10) causes the positioning pawl 1332 to rotate in the forward direction as shown in Fig. 27(C). When the tip end of the claw 134 turns away from the tip end of the positioning tooth U12, 'the positioning ratchet bribe (and the attached rotating structure is rotated in accordance with the biasing force of the return spring until the positioning tooth 13_ is connected as shown in Fig. 27(D) Claw 1336 to avoid uncontrolled rotation of the ratchet (10) and the accompanying rotating member. When the shifting lever 1320 continues toward a second release position (eg, the range of the shift lever 1320 shown in Figure 27(f) When the rear end is rotated in the reverse direction, the circular f portion 60 of the cam plate passes through the cam roller 1344 shown in Fig. 27(D), and the cam roller 1344 rotates the cam plate 1324 as shown in Fig. 27(E). This will allow the positioning pawl 1332 to rotate counter-rotating so that the claw 1336 removes the positioning tooth i3i6 and the claw 1340 engages with the positioning tooth 1308. As a result, the positioning ratchet 13〇4 and its accompanying rotating member are positioned for the bicycle transmission In the desired state, the shift lever 1320 can be returned to the position of the first release member shown in Figures 27(G) & 27(H). If the operating system uses a positioning claw and positioning as in the conventional system. When the ratchet controls the shifting operation, the claws 134 will continue to be fixed. The teeth 1312 are engaged, straight 86029 -36 - 1259160 until the shift lever reaches the end of its range of motion (second release member position) as indicated by W27 (F). In addition, the 'positioning claw 1 332 will not be reversed, so that the claws (10) moving away from the positioning tooth m6 and engaging the claw (10) with the positioning tooth (10) until the shift lever 1320 is rotated a distance toward the first release member position. This does not require the use of the shift control mechanism described herein because ^ The cam plate 1324 allows the positioning claw to complete the shifting operation when the shift lever 1320 starts to rotate back to the first release, and even if the shift lever 1320 is rotated in the reverse direction, in addition, if the cam is engaged with the cam (4) The additional cam plate of the same type is attached to the shift lever 1320 in a manner that it is continuously contacted with the cam roller 1344, and the plurality of shifting operations can be further changed from the position shown in FIG. η(8) by changing the mast (1). Reverse rotation is accomplished. Figure 28 illustrates a shifting lever assembly 14A incorporating the teachings of the embodiment of Figure 2A. As in the embodiment of Figure 20, a cam gear 14 has two controls. Positioning claw 1474 of cam roller 1478 The cam gear 1450 is coaxially and rotatably mounted to the positioning ratchet 1458. The cam gear 1450 includes a plurality of circumferentially disposed cam teeth 1454 and a plurality of circumferentially disposed cam drive teeth 1459. A cam drives the pawl 462 to rotate Mode transmission - The pivot 1466 is mounted to a shift lever 1486 and reverse biased by a spring 147. When the shift lever I486 is reversed (typically the direction in which the wire is released), the cam drive pawl 1462 and the plurality of cam drives One of the teeth 1459 engages and reverses the cam gear 1450. Thereafter, one of the plurality of cam teeth 1454 is pressed against the cam roller 1478 and causes the positioning pawl 1474 to rotate in the same manner as in Figs. 27(a)-27(d). When the cam tooth 1454 passes the cam roller 1478, the positioning claw 1474 rotates in the reverse direction, and in the same manner as the embodiment shown in Fig. 27(E), the shifting operation is completed 86029 - 37 - 1259160. When the shift lever rotates in the forward direction, the cam drives the pawl. Separate from the corresponding cam drive tooth 1459. As shown in Fig. 27(A)_27 (in the case of the embodiment shown in Fig. 2), the cam gear 1454 on the cam gear 1450 is rotated back to the first release of the shift lever 1 4 8 6 to the first release. Even if the shift lever 1 4 8 6 is still rotating in the reverse direction, the sister-in-law will be able to complete the shifting operation directly. The shifting operation can be completed by the shifting lever 1 486. 'Therefore, the plurality of cam teeth 1454 can be continuously pressed against the cam roller 14 7 8.
