Description

Technical Field

[0001] This invention relates to a bicycle derailleur grip, and more particularly to a derailleur grip that makes it very easy to thread cables through. Background Technology

[0002] Currently available derailleur grips can be divided into two types: rotary and lever-type. Users can control the bicycle's gear shifting by rotating the handlebar or moving the lever to wind or unwind the cable running through the derailleur grip. Because the internal structure of existing derailleur grips is relatively complex, the process of threading and replacing cables is cumbersome, making it inconvenient. Therefore, there is still room for improvement in existing derailleur grips. Summary of the Invention

[0003] In view of this, the main objective of the present invention is to provide a gearshift grip that has a simple structure and is conducive to cable routing.

[0004] To achieve the aforementioned main objectives, the gearshift lever of the present invention includes a housing, a glove tube, a wire reel, and a rotating housing. The housing has a body and a guide portion extending laterally from the body. The body has a front, a back, a body shaft hole penetrating the front and back, a housing cavity recessed from the back to the front, and a wire inlet extending from the front to the back and communicating with the housing cavity. The guide portion has a wire outlet hole communicating with the housing cavity. The glove tube has a sleeve shaft hole, and a front end of the glove tube is connected to the body, such that the sleeve shaft hole communicates with the body shaft hole. The wire reel has a reel hole through which it is rotatably fitted. The handle sleeve includes a front surface and a guide ring wall. The front surface of the spool faces the bottom of the housing chamber. The guide ring wall protrudes from the front surface of the spool toward the bottom of the housing chamber. The guide ring wall has an inner ring surface, an outer ring surface, an arc segment, and a curved segment adjacent to the arc segment. The arc segment has a first end, and the curved segment has a second end opposite to the first end and closer to the center of the spool hole than the first end. The first end and the second end together form a wire passage opening corresponding to the wire exit hole. A wire guide groove communicating with the wire passage opening is formed between the guide ring wall and the handle sleeve. The rotating housing is mounted on the handle sleeve in a way that drives the spool to rotate.

[0005] With the above-described technical features, when assembled with a wire, a free end of the wire passes through the wire entry port of the housing, allowing the wire to be guided by the wire guide groove to pass through the wire entry port and exit through the wire exit hole. A fixed end of the wire, opposite the free end, is stopped at the wire entry port. In other words, the internal structure of the gearshift lever of the present invention facilitates the insertion of the wire, and the gearshift lever of the present invention allows for smooth winding or unwinding of the wire when shifting gears. Therefore, the gearshift lever of the present invention can be quickly installed with the wire and is very easy to operate.

[0006] Preferably, the front end of the glove tube is exposed in the spool hole of the wire spool to form a wire abutment portion, and the wire abuts against the wire abutment portion when the free end of the wire is stretched by an external force; the wire guide groove is defined between the wire abutment portion of the glove tube and the inner ring surface of the guide ring wall.

[0007] Preferably, the first end of the coil has a stop, and the second end of the coil has a cover that connects to the stop, the stop and the cover together forming the wire passage opening. In this way, the free end of the wire is guided by the stop and can more easily pass through the wire passage opening.

[0008] Preferably, when the free end of the wire passes through the wire pass-through opening, the free end of the wire abuts against the outer annular surface of the spool.

[0009] Preferably, a guide member is provided inside the wire exit hole of the guide part, and the guide member and the inner wall of the wire exit hole together define a guide ring rail.

[0010] Preferably, the free end of the wire is inserted into the wire entry port of the housing and accommodated in the wire guide groove. The free end of the wire is guided by the wire guide groove to pass through the wire entry port and is guided by the guide ring rail of the housing to exit through the end of the wire exit hole of the housing.

[0011] Preferably, the main shaft hole of the sleeve has a large diameter portion and a small diameter portion communicating with the large diameter portion. The large diameter portion has a first recess and a second recess adjacent to the first recess. A protrusion is formed between the first and second recesses, and the protrusion has an inner flange. The small diameter portion has a third recess adjacent to the first recess, and the third recess has a flange. The front end of the handle has a first locking portion, and a second locking portion and a third locking portion adjacent to the first locking portion. The first locking portion has an outer flange, and the second locking portion has a locking portion. When the front end of the handle is inserted into the main shaft hole of the sleeve, the outer flange of the first locking portion abuts against the first recess, the second locking portion abuts against the inner flange, the locking portion is locked into the second recess, and the third locking portion abuts against the flange of the third recess. In this way, the glove tube can be securely inserted into the shaft hole of the body of the casing.

[0012] Preferably, the second recess has a positioning notch, and the second locking portion has a positioning rib that connects to the locking portion, the positioning rib fitting into the positioning notch. In this way, the glove tube can be more securely inserted into the shaft hole of the body of the sleeve.

[0073] Please see Figure 4 and Figure 5The housing 10 has a body 11 and a guide portion 17 extending laterally forward from the body 11. The body 11 has a front side 12, a back side 13, a body shaft hole 14 penetrating the front and back sides 12 and 13, a housing chamber 15 recessed from the back side 13 to the front side 12, and a wire entry port 16 extending from the front side 12 to the back side 13 and communicating with the housing chamber 15. The body shaft hole 14 has a large diameter portion 141 and a small diameter portion 145 communicating with the large diameter portion 141. The inner wall surface of the large diameter portion 141 is provided with three first recesses 142 and two second recesses 143 disposed between the first recesses 142, and each second recess 143 has a positioning notch 143a. The first and second recesses 142 and 143 are arranged in a ring relative to the main body shaft hole 14, and a protrusion 144 is formed between each of the first and second recesses 142 and 143. The bottom surface of each protrusion 144 is provided with an inner flange 144a protruding toward the center of the main body shaft hole 14. The small diameter portion 145 has a third recess 146. The bottom surface of the third recess 146 is provided with a flange 146a protruding toward the center of the main body shaft hole 14, and the inner wall surface of the small diameter portion 145 also has a threaded hole 147 that extends vertically. The wall surface of the housing chamber 15 is provided with a plurality of toothed grooves 151 (seven in this embodiment, but not limited to seven). The guide section 17 has a wire exit hole 171 communicating with the housing chamber 15. A guide member 18 is disposed within the wire exit hole 171, and a guide ring rail R is defined jointly between the guide member 18 and the inner wall of the wire exit hole 171. Figure 3 and Figure 18 As shown), in some cases, the guide portion 17 and the guide member 18 can also be integrally formed, and an adjusting screw 19 is locked at one end of the guide portion 17 (as shown). Figure 1 (As shown).

[0074] Please see Figure 6 The glove tube 20 has a sleeve shaft hole 21 and a front end 22. The front end 22 has three first abutment portions 221, two second abutment portions 222, and one third abutment portion 223. The first abutment portions 221, the second abutment portions 222, and the third abutment portions 223 are arranged in a ring relative to the sleeve shaft hole 21. Each first abutment portion 221 is provided with an outer flange 221a protruding in the opposite direction to the center of the sleeve shaft hole 21. Each second abutment portion 222 has a locking portion 222a and a positioning rib 222b connected to the locking portion 222a. Furthermore, the glove tube 20 has two first annular flanges 23 at the front end, two spaced-apart retaining flanges 24 on the outer periphery of the rear end, a second annular flange 25 adjacent to the first annular flanges 23, and three third annular flanges 26 located at the rear end. Please refer to further details. Figure 7The front end 22 of the glove tube 20 is fixed in the main shaft hole 14 of the housing 10. On the one hand, the outer flange 221a of each first locking part 221 abuts against the bottom surface of each first recess 142, and the third locking part 223 abuts against the flange 146a of the third recess 146. On the other hand, each second locking part 222 abuts against each inner flange 144a, and each inserting part 222a is inserted into each second recess 143. The positioning rib 222b is fitted into the positioning notch 143a, thereby completing the positioning of the glove tube 20.

[0075] Please see Figure 2 and Figure 3 The connecting ring 30 is an integrally formed ring component, having a front-to-back through-hole 31 and a top-to-bottom through-hole 32. For example... Figure 2 As shown, the connecting ring 30 is located in the main shaft hole 14 of the sleeve 10. A fixing screw 80 is then used to pass through the screw hole 147 of the sleeve 10 and the screw hole 32 of the connecting ring 30, thereby securely locking the glove tube 20 and the connecting ring 30 in the main shaft hole 14 of the sleeve 10, so that the sleeve shaft hole 21 and the main shaft hole 14 are connected to each other.

[0076] Please see Figures 8 to 11 The reel 40 has a reel hole 41, a reel front 42, a guide ring wall 43 protruding from the reel front 42, and a reel back 50 opposite to the reel front 42. The guide ring wall 43 has an inner ring surface 44, an outer ring surface 45, an arc segment 46, and a curved arc segment 47 adjacent to the arc segment 46. The arc segment 46 is a perfect circular arc relative to the center of the reel hole 41, and the arc segment 46 has a first end 461 with a stop 462. The curved arc segment 47 has a second end 471, which is closer to the center of the reel hole 41 than the first end 461, and has a covering portion 472 connecting to the stop 462. The stop 462 and the covering portion 472 together form a wire passage 49. Figure 10 As shown, the reverse side 50 of the coil has three locking blocks 51 arranged in a ring around the corresponding coil holes 41. One of the locking blocks 51 has a first insertion portion 52 for inserting one end of a spring 81 (as shown). Figure 11 As shown), the reverse side 50 of the coil has a rib 54, and a spring receiving groove 55 is formed between the rib 54 and another locking block 51 for placing a spring 83. Furthermore, as... Figure 9 As shown, the spool 40 is fitted onto the front end 22 of the glove tube 20 through a hole 41, with the front end 22 of the glove tube 20 exposed through the hole 41 of the spool 40 to form a shape similar to... Figure 2 The wire abutment portion 224 is shown, and a wire guide groove 48 is formed between the wire abutment portion 224 and the inner ring surface 44 of the guide ring wall 43. For example... Figure 2As shown, the first annular flange 23 of the glove tube 20 is pressed against the inner wall of the disc hole 41 to prevent the spool 40 from sliding back and forth. At this time, the spring piece 83 fixed to the back side 50 of the spool will engage with one of the toothed grooves 151 of the housing 10 (e.g., Figure 11 (As shown).

[0077] Please see Figure 3 The rotating housing 60 has a rotating housing shaft hole 61, an annular receiving portion 62, and a rotating shaft portion 65 connecting the annular receiving portion 62. The bottom surface of the annular receiving portion 62 has three pushing blocks 63, one of which has a second insertion portion 64 for providing insertion of the other end of the spring 81 (e.g., ...). Figure 11 (As shown); the outer peripheral surface of the rotating shaft portion 65 has multiple longitudinal ribs 66 (the number is not limited), and these longitudinal ribs 66 are arranged in a ring at equal intervals relative to the axial direction of the rotating shell 60. Furthermore, as... Figure 2 As shown, the rotating housing 60 is fitted onto the handlebar sleeve 20 through the rotating housing shaft hole 61 at the rear end. At this time, the handlebar sleeve 20 abuts against the inner wall of the rotating housing shaft hole 61 with its second annular flange 25, and abuts against the rear end of the rotating shaft portion 65 of the rotating housing 60 with its retaining flange 24, thereby preventing the rotating housing 60 from detaching from the handlebar sleeve 20. For example... Figure 11 As shown, at this time, the annular receiving part 62 of the rotating shell 60 is engaged with the back 50 of the spool 40, and the two ends of the spring 81 push against the pushing block 63 of the rotating shell 60 and the locking block 51 of the spool 40 respectively, so that the two are locked against each other, and the rotating shell 60 can drive the spool 40 to rotate relative to the handle sleeve 20.

[0078] Please see Figure 2 and Figure 3 The grip sleeve 70 has a grip sleeve shaft hole 71. The inner wall surface of the grip sleeve shaft hole 71 has multiple longitudinal recesses 72 (the number is unlimited). The grip sleeve 70 is fitted onto the rotating shell 60 through the grip sleeve shaft hole 71, and each longitudinal recess 72 is engaged and fixed with the longitudinal protrusions 66 of the rotating shell 60, so that the grip sleeve 70 can drive the rotating shell 60 to move synchronously when subjected to external force.

[0079] The above describes the structural features of the gearshift grip 1 of the present invention. The following will further introduce the usage of the gearshift grip 1 of the present invention and its effects.

[0080] Please see Figures 12 to 15In practical applications, the gearshift lever 1 of the present invention is used in conjunction with a wire 90 (e.g., a shift cable). The wire 90 has a body 91, a free end 92 connected to the body 91, and a fixed end 93 connected to the body 91 and opposite to the free end 92. First, the free end 92 of the wire 90 is inserted into the wire entry 16 of the housing 10, so that the body 91 of the wire 90 abuts against the inner annular surface 44 of the spool 40 and is accommodated in the wire guide groove 48. At this time, the free end 92 of the wire 90 is guided by the stop 462, so it is easier to pass through the wire passage 49 and abut against the outer annular surface 45 of the guide ring wall 43. Then, the free end 92 of the wire 90 is guided by the guide ring rail R of the housing 10 (e.g., Figure 18 As shown), the wire 90 is then passed through the end of the wire exit hole 171 of the housing 10, while the fixed end 93 of the wire 90 is stopped at the wire entrance 16. In this way, the wire 90 can be threaded into the gear shift lever 1 of the present invention, and the installation process is very easy.

[0081] When the gearshift lever 1 of the present invention shifts to a high gear, an external force is applied to rotate the lever sleeve 70 counterclockwise. At this time, the lever sleeve 70, together with the rotating housing 60, drives the cable reel 40 to rotate counterclockwise relative to the lever sleeve tube 20, causing the free end 92 of the cable 90 to be tightened by a rear derailleur (not shown). At this time, the body 91 of the cable 90 is attached to the cable abutment portion 224 of the lever sleeve tube 20 (e.g., ...). Figure 16 (As shown), to achieve the effect of shifting to a higher gear. When the gearshift lever 1 of the present invention shifts to a lower gear, an external force needs to be applied to rotate the lever sleeve 70 clockwise. At this time, the lever sleeve 70, together with the rotating housing 60, drives the coil 40 to rotate clockwise relative to the lever sleeve tube 20, causing the free end 92 of the cable 90 to be wound. Therefore, the body 91 of the cable 90 will abut against the outer ring surface 45 of the guide ring wall 43 of the coil 40 (as shown). Figure 17 As shown), this achieves the effect of shifting to a lower gear. It should be noted that when force is applied to rotate the grip sleeve 70, the spring pieces 83 fixed to the cable reel 40 sequentially engage with the respective toothed grooves 151 of the sleeve housing 10, thereby achieving the gear shifting of the gear lever 1 of the present invention. Tightening the adjusting screw 19 locked to the guide portion 17 of the sleeve housing 10 allows adjustment of the tension of the free end 92 of the cable 90.

[0082] In summary, when the gearshift lever 1 of the present invention is used with the cable 90, the free end 92 of the cable 90 is allowed to pass through the cable entry 16 of the housing 10 and enter the housing chamber 15. The cable 90 is then guided by the cable guide groove 48 to pass through the cable through-hole 49 and exit through the cable exit hole 171, while the fixed end 93 of the cable 90 is stopped at the cable entry 16. In other words, the internal structure of the gearshift lever 1 of the present invention facilitates the insertion of the cable 90 and allows for smooth winding and unwinding of the cable 90 during gear shifting. Therefore, the gearshift lever 1 of the present invention can be quickly installed with the cable 90 and is very easy to operate.
