這裡，如圖4及6所示，前撥鏈器10還包括偏置構件36，其可操作地提供在導鏈器14及第二連桿構件32之間，以將導鏈器14朝向縮回位置偏置。或者，如果需要及/或希望，偏置構件36可配置成將導鏈器14偏置向延伸位置。在所示實施例中，如圖4所示，偏置構件36是扭力彈簧。偏置構件36具有安裝在樞銷38上的盤繞部分，樞銷38將第二連桿構件32樞轉地支撐到基座構件12。偏置構件36具有與導鏈器14接合的第一端及與第二連桿構件32接合的第二端。Here, as shown in FIGS. 4 and 6 , the front derailleur 10 further includes a biasing member 36 , which is operatively provided between the chain guide 14 and the second link member 32 to bias the chain guide 14 toward the retracted position. Back position offset. Alternatively, the biasing member 36 may be configured to bias the chain guide 14 toward the extended position, if needed and/or desired. In the illustrated embodiment, as shown in FIG. 4 , the biasing member 36 is a torsion spring. The biasing member 36 has a coiled portion mounted on a pivot pin 38 that pivotally supports the second link member 32 to the base member 12 . The biasing member 36 has a first end that engages the chain guide 14 and a second end that engages the second linkage member 32 .

基座構件12是由金屬材料或塑料材料等適當的材料構成的剛性構件。基座構件12還具有容納操作纜線18的線纜容納部40。如圖5所示，纜線容納部40具有階梯孔42，使得外殼抵接表面44形成在第一大直徑孔段46及第二小直徑孔段48之間。第一大直徑孔段46係尺寸化成用於容納與外殼抵接表面抵接的外殼18a。第二小直徑孔段48係尺寸化成用於容納穿過其中的內線18b。The base member 12 is a rigid member made of an appropriate material such as metal material or plastic material. The base member 12 also has a cable accommodating portion 40 that accommodates the operating cable 18 . As shown in FIG. 5 , the cable receiving portion 40 has a stepped hole 42 such that a housing abutment surface 44 is formed between a first large diameter hole section 46 and a second small diameter hole section 48 . The first large diameter bore segment 46 is sized to receive the housing 18a in abutment against the housing abutment surface. The second small diameter bore segment 48 is sized to receive the inner wire 18b therethrough.

現在，將更詳細地討論導鏈器14。如圖8至14所示，導鏈器14包括內板50及外板52。內板50及外板52被建構成在其間形成導鏈槽54。這裡，內板50包括面向導鏈槽54的內表面50a。內板50還包括從內表面50a突出到導鏈槽54中的突出部件50b。突出部件50b沿內板50的下邊緣設置。Now, the chain guide 14 will be discussed in more detail. As shown in FIGS. 8 to 14 , the chain guide 14 includes an inner plate 50 and an outer plate 52 . The inner plate 50 and the outer plate 52 are configured to form a chain guide slot 54 therebetween. Here, the inner plate 50 includes an inner surface 50 a facing the chain guide groove 54 . The inner plate 50 also includes a protruding member 50b protruding from the inner surface 50a into the chain guide groove 54 . The protruding part 50b is provided along the lower edge of the inner panel 50 .

在第一實施例中，導鏈器14還包括上游連接部件56及下游連接部件58。上游連接部件56連接內板50及外板52的上游端。下游連接部件58連接內板50及外板52的下游端。如本文所用，用語「上游」及「下游」是指在對第一鏈輪S1及第二鏈輪S2施加向前踩踏動作期間，相對在導鏈槽54內的自行車鏈條CN的鏈條驅動方向CD。換言之，內板50與外板52的內表面彼此相面對而在其間形成導鏈槽54，以容納自行車鏈條CN。In the first embodiment, the chain guide 14 further includes an upstream connecting member 56 and a downstream connecting member 58 . The upstream connection member 56 connects the upstream ends of the inner panel 50 and the outer panel 52 . The downstream connection member 58 connects the downstream ends of the inner panel 50 and the outer panel 52 . As used herein, the terms "upstream" and "downstream" refer to the chain drive direction CD relative to the bicycle chain CN within the chain guide groove 54 during the forward pedaling action applied to the first sprocket S1 and the second sprocket S2. . In other words, inner surfaces of the inner plate 50 and the outer plate 52 face each other to form a chain guide groove 54 therebetween to accommodate the bicycle chain CN.

更具體地，響應於變速器的致動，藉由拉動操作纜線18的內線18b，導鏈器14相對於基座構件12於遠離自行車車架F的向外方向移動。因此，響應於操作拉纜線18的釋放操作，外板52接觸並橫向切換自行車鏈條CN，使得自行車鏈條CN相對於自行車車架F於向內方向從第一鏈輪S1移動到第二個鏈輪S2。此外，響應於變速器的致動，藉由拉動操作纜線18的內線18b，導鏈器14相對於基座構件12於遠離自行車車架F的向外方向移動。如此，導鏈器14可響應於變速器的致動而選擇性地將自行車鏈條CN定位在第一鏈輪S1及第二鏈輪S2中的一個上。More specifically, the chain guide 14 moves in an outward direction away from the bicycle frame F relative to the base member 12 by pulling the inner wire 18b of the operating cable 18 in response to actuation of the derailleur. Accordingly, in response to the release operation of the operating cable 18, the outer plate 52 contacts and laterally shifts the bicycle chain CN so that the bicycle chain CN moves in an inward direction relative to the bicycle frame F from the first sprocket S1 to the second chain. Wheel S2. Further, the chain guide 14 moves in an outward direction away from the bicycle frame F relative to the base member 12 by pulling the inner wire 18b of the operating cable 18 in response to actuation of the derailleur. As such, the chain guide 14 can selectively position the bicycle chain CN on one of the first sprocket S1 and the second sprocket S2 in response to actuation of the derailleur.

現在，將更詳細地討論導鏈器14。導鏈器附接元件20基本上包括第一部件60。第一部件60被建構為部分地覆蓋內板50的內表面50a，該內表面50a面向導鏈槽54，於其中有導鏈器附接元件20附接到內板50。這裡，第一部件60也至少相對於內板50為懸臂。Now, the chain guide 14 will be discussed in more detail. The chain guide attachment element 20 basically includes a first part 60 . The first member 60 is configured to partially cover the inner surface 50 a of the inner plate 50 facing the chain guide groove 54 in which the chain guide attachment element 20 is attached to the inner plate 50 . Here too, the first part 60 is cantilevered at least relative to the inner panel 50 .

第一部件60建構成在導鏈器附接元件20附接到導鏈器14的內板50及前撥鏈器10安裝到自行車車架F的狀態下，在向內換檔操作期間防止鏈條從前鏈輪總成的鏈輪脫落。這裡，第一部件60建構成防止在向內換檔操作期間鏈條從前鏈輪總成FS的第二鏈輪S2脫落。換言之，第一部件60建構成防止在向內換檔操作期間鏈條從前鏈輪總成的最小鏈輪脫落。The first part 60 is constructed to prevent the chain during an inward shifting operation in a state where the chain guide attachment member 20 is attached to the inner plate 50 of the chain guide 14 and the front derailleur 10 is mounted to the bicycle frame F. The sprocket comes off the front sprocket assembly. Here, the first member 60 is configured to prevent the chain from coming off the second sprocket S2 of the front sprocket assembly FS during an inward shifting operation. In other words, the first member 60 is configured to prevent the chain from falling off the smallest sprocket of the front sprocket assembly during an inward shifting operation.

具體地，第一部件60包括支座(abutment) 60a，其建構成藉由使鏈條接觸支座60a來防止鏈條在向內換檔操作期間從前鏈輪總成的最小鏈輪脫落。支座60a設置在第一部件60的前端的尖端處且相對於內板50的內表面50a向內朝向導鏈器14的外板52突出。支座60a與連接部件64隔開。Specifically, the first component 60 includes an abutment 60a configured to prevent the chain from coming off the smallest sprocket of the front sprocket assembly during an inward shifting operation by contacting the chain with the abutment 60a. The standoff 60 a is provided at the tip of the front end of the first member 60 and protrudes inwardly toward the outer plate 52 of the chain guide 14 relative to the inner surface 50 a of the inner plate 50 . The mount 60 a is spaced apart from the connection part 64 .

支座60a設置在導鏈器附接元件20的最前部。與導鏈器附接元件20的任何其他部分相比，支座60a係最遠地突出到導鏈槽54中。在進行向內換檔操作時，隨著鏈條CN從第一鏈輪S1被引導到第二鏈輪S2，鏈條CN開始從第一鏈輪S1脫離，然後移動到第二鏈輪S2上。然而，如果鏈條CN在向內方向朝向自行車車架F移動至遠處，則鏈條CN接觸支座60a以防止鏈條CN脫離到第二鏈輪S2的內側。The mount 60 a is provided at the frontmost portion of the chain guide attachment element 20 . The abutment 60a protrudes furthest into the chain guide groove 54 than any other portion of the chain guide attachment element 20 . During an inward shift operation, as the chain CN is guided from the first sprocket S1 to the second sprocket S2, the chain CN starts to disengage from the first sprocket S1 and then moves onto the second sprocket S2. However, if the chain CN moves far in the inward direction toward the bicycle frame F, the chain CN contacts the standoff 60a to prevent the chain CN from coming off to the inner side of the second sprocket S2.

此外，第一部件60建構成在向外換檔操作期間與鏈條CN接觸。具體地，第一部件60包括在向外換檔操作期間接觸鏈條CN的鏈條接觸表面60b。較佳地，第一部件60的鏈條接觸表面60b位於從內板50的底部周邊邊緣向下處。這裡，第一部件60相對於內板50呈懸臂式，其中導鏈器附接元件20附接到內板50。如此，導鏈器附接元件20可響應於在向外換檔操作期間與鏈條CN的接觸而相對於導鏈器14變形。Furthermore, the first member 60 is configured to be in contact with the chain CN during an outward shifting operation. Specifically, the first member 60 includes a chain contact surface 60b that contacts the chain CN during an outward shifting operation. Preferably, the chain contact surface 60b of the first member 60 is located downward from the bottom peripheral edge of the inner plate 50 . Here, the first part 60 is cantilevered with respect to the inner plate 50 to which the chain guide attachment element 20 is attached. As such, the chain guide attachment element 20 may deform relative to the chain guide 14 in response to contact with the chain CN during an outward shifting operation.

導鏈器附接元件20還包括第二部件62及連接部件64。連接部件64連接第一部件60及第二部件62。如此，第二部件62至少部分地與第一部件60間隔開。因此，第一部件60在分離區域R處至少部分地與第二部件62間隔開。較佳地，如在第一實施例中，第一部件60、第二部件62及連接部件64是整體式之一體式構件。例如，第一部件60、第二部件62及連接部件64是樹脂構件。例如，導鏈器附接元件20由硬合成樹脂(例如聚縮醛等)一體模製而成，其具有彈性及恢復性，以在向外換檔操作期間第一部件60相對第二部件62偏轉後，返回其原始狀態。這裡，鏈條接觸表面60b在連接部件64及支座60a之間延伸。此外，第二部件62具有第一端62a及第二端62b。第二端62b連接到連接部件64。The chain guide attachment element 20 also includes a second part 62 and a connecting part 64 . The connection part 64 connects the first part 60 and the second part 62 . As such, the second component 62 is at least partially spaced from the first component 60 . Thus, the first component 60 is at least partially spaced apart from the second component 62 at the separation region R. As shown in FIG. Preferably, as in the first embodiment, the first part 60 , the second part 62 and the connection part 64 are integrally formed as one-piece components. For example, the first member 60, the second member 62, and the connecting member 64 are resin members. For example, the chain guide attachment member 20 is integrally molded from a hard synthetic resin such as polyacetal or the like, which has elasticity and restorative properties so that the first part 60 is opposed to the second part 62 during an outward shifting operation. After deflection, it returns to its original state. Here, the chain contact surface 60b extends between the connecting member 64 and the seat 60a. In addition, the second member 62 has a first end 62a and a second end 62b. The second end 62b is connected to the connecting member 64 .

參照圖8及圖9，導鏈器附接元件20還包括固定部件66。在第一實施例中，固定部件66位於連接部件64相鄰處。固定部件66被建構成附接至導鏈器14。固定部件66不含金屬材料。這裡，固定部件66包括建構成容納緊固件68的緊固件開口66a。在第一實施例中，緊固件68是將導鏈器附接元件20緊固到內板50的鉚釘。緊固件68還將下游連接部件58的凸片部58a連接到內板50。更具體地，緊固件68延伸穿過導鏈器附接元件20的緊固件開口66a，然後穿過下游連接部件58的開口58b並穿過內板50的開口50c。Referring to FIGS. 8 and 9 , the chain guide attachment element 20 further includes a fixing member 66 . In the first embodiment, the fixing part 66 is located adjacent to the connecting part 64 . The fixing member 66 is configured to be attached to the chain guide 14 . The fixing member 66 does not contain metal material. Here, the securing member 66 includes a fastener opening 66 a configured to receive a fastener 68 . In the first embodiment, the fasteners 68 are rivets that fasten the chain guide attachment element 20 to the inner plate 50 . The fastener 68 also connects the tab portion 58 a of the downstream connection member 58 to the inner panel 50 . More specifically, the fastener 68 extends through the fastener opening 66 a of the chain guide attachment element 20 , then through the opening 58 b of the downstream connecting member 58 and through the opening 50 c of the inner plate 50 .

較佳地，如圖12所示，第一部件60及第二部件62中的至少一個包括建構成與內板50接合的接合部。這裡，第一部件60包括接合部70。此外，這裡，第二部件62包括接合部72。在第一實施例中，接合部70包括提供到第一部件60的第一鉤70a。第一鉤70a在第一位置處鉤到內板50上。在第一實施例中，接合部72包括提供到第二部件62的第二鉤72a。第二鉤72a在與第一鉤70a的第一位置間隔開的第二位置處鉤到內板50上。Preferably, as shown in FIG. 12 , at least one of the first part 60 and the second part 62 includes a joint portion configured to engage with the inner panel 50 . Here, the first component 60 includes the engaging portion 70 . Furthermore, here, the second component 62 includes the engagement portion 72 . In the first embodiment, the engagement portion 70 includes a first hook 70 a provided to the first member 60 . The first hook 70a is hooked onto the inner panel 50 at the first position. In the first embodiment, the engaging portion 72 includes the second hook 72 a provided to the second member 62 . The second hook 72a hooks onto the inner panel 50 at a second position spaced from the first position of the first hook 70a.

參考圖9，導鏈器附接元件20還包括容納空間74，其定義在第一部件60及第二部件62彼此間隔開的位置處。更具體地，容納空間74建構成至少部分地容納導鏈器14的內板50的突出部件50b。換言之，在導鏈器附接元件20安裝至前撥鏈器10的導鏈器14的狀態下，突出部件50b至少部分地位於容納空間74處。內板50的突出部件50b從內板50向導鏈槽54突出。在導鏈器附接元件20附接到導鏈器14的內板50的狀態下，第一部件60及第二部件62位於內板50的突出部件50b相鄰處。內板50的突出部件50b至少部分地定義了第一部件60及第二部件62之間的分離區域R。如圖13及14中所見，在導鏈器附接元件20附接至該導鏈器14的該內板50的狀態下，第一部件60的至少一部分比內板50的突出部件50b更遠地突出到導鏈器14的導鏈槽54中。Referring to FIG. 9 , the chain guide attachment element 20 also includes a receiving space 74 defined at a location where the first part 60 and the second part 62 are spaced apart from each other. More specifically, the accommodation space 74 is configured to at least partially accommodate the protruding part 50 b of the inner plate 50 of the chain guide 14 . In other words, in a state where the chain guide attachment member 20 is mounted to the chain guide 14 of the front derailleur 10 , the protruding member 50 b is at least partially located at the accommodation space 74 . The protruding member 50b of the inner panel 50 protrudes from the inner panel 50 to the chain guide groove 54 . In a state where the chain guide attachment member 20 is attached to the inner plate 50 of the chain guide 14 , the first part 60 and the second part 62 are located adjacent to the protruding part 50 b of the inner plate 50 . The protruding part 50b of the inner panel 50 at least partially defines a separation region R between the first part 60 and the second part 62 . As seen in FIGS. 13 and 14 , in a state where the chain guide attachment element 20 is attached to the inner plate 50 of the chain guide 14 , at least a portion of the first part 60 is farther than the protruding part 50 b of the inner plate 50 . Protrudes into the chain guide groove 54 of the chain guide 14 .

此外，在第一實施例中，在該導鏈器附接元件20附接至該導鏈器14的該內板50的狀態下，該第二部件62的至少一部分比該內板50的該突出部件50b更遠地突出至該導鏈器14的導鏈槽54中。特別地，第二部件62從第二部件62的第一端62a到第二部件62的第二端62b逐漸變厚。較佳地，第二部件62的第二端62b比內板50的突出部件50b更突出到導鏈器14的導鏈槽54中。例如，第二部件62的第二端62b比內板50的突出部件50b更突出到導鏈器14的導鏈槽54中約0.5公釐。因此，鏈條CN通常被防止接觸到內板50的突出部件50b。然而，在向外換檔操作期間，第一部件60可相對於第二部件62向內朝向自行車車架F偏轉，使得鏈條CN接觸內板50的突出部件50b。Furthermore, in the first embodiment, in a state where the chain guide attachment element 20 is attached to the inner plate 50 of the chain guide 14 , at least a part of the second member 62 is larger than the inner plate 50 of the chain guide 14 . The protruding part 50 b protrudes further into the chain guide groove 54 of the chain guide 14 . In particular, the second member 62 gradually becomes thicker from the first end 62a of the second member 62 to the second end 62b of the second member 62 . Preferably, the second end 62b of the second part 62 protrudes further into the chain guide groove 54 of the chain guide 14 than the protruding part 50b of the inner plate 50 . For example, the second end 62 b of the second member 62 protrudes about 0.5 millimeters further into the chain guide groove 54 of the chain guide 14 than the protruding member 50 b of the inner plate 50 . Therefore, the chain CN is normally prevented from contacting the protruding part 50b of the inner panel 50 . However, during an outward shifting operation, the first member 60 may deflect inwardly toward the bicycle frame F relative to the second member 62 such that the chain CN contacts the protruding member 50 b of the inner plate 50 .

現參考圖15至18，示出了根據第二實施例的前撥鏈器110。鑑於第一實施例及第二實施例之間的相似性，第二實施例中與第一實施例的部分相同的部分將被賦予與第一實施例的部分相同的元件符號。此外，為了簡潔，可省略第二實施例與第一實施例的部分相同之部分的描述。Referring now to FIGS. 15 to 18 , there is shown a front derailleur 110 according to a second embodiment. In view of the similarity between the first embodiment and the second embodiment, the parts of the second embodiment that are the same as the parts of the first embodiment will be given the same reference numerals as the parts of the first embodiment. In addition, descriptions of parts of the second embodiment that are the same as those of the first embodiment may be omitted for brevity.

在第二實施例中，前撥鏈器110與前撥鏈器10的不同之處在於前撥鏈器110提供有修改的導鏈器114及修改的導鏈器附接元件120。因此，這裡，前撥鏈器110包括基座構件12、導鏈器114、連桿總成16及導鏈器附接元件120。In the second embodiment, the front derailleur 110 differs from the front derailleur 10 in that the front derailleur 110 is provided with a modified chain guide 114 and a modified chain guide attachment element 120 .

在第二實施例中，導鏈器114包括內板150及外板152。內板150及外板152被建構成在其間形成導鏈槽154。在第二實施例中，導鏈器114還包括上游連接部件156及下游連接部件158。在第二實施例中，導鏈器114與前撥鏈器10的導鏈器14相同，除了內板150已被修改。這裡，內板150具有內表面150a及突出部件150b，其中突出部件150b的寬度比導鏈器14的突出部件50b寬，且內表面150a的寬度小於內表面50a的寬度。導鏈器114以與導鏈器14相同的方式來作用。In the second embodiment, the chain guide 114 includes an inner plate 150 and an outer plate 152 . The inner plate 150 and the outer plate 152 are configured to form a chain guide slot 154 therebetween. In the second embodiment, the chain guide 114 further includes an upstream connecting member 156 and a downstream connecting member 158 . In the second embodiment, the chain guide 114 is identical to the chain guide 14 of the front derailleur 10, except that the inner plate 150 has been modified. Here, the inner plate 150 has an inner surface 150a and a protruding part 150b, wherein the protruding part 150b is wider than the protruding part 50b of the chain guide 14, and the width of the inner surface 150a is smaller than that of the inner surface 50a. Chain guide 114 functions in the same manner as chain guide 14 .

在第二實施例中，導鏈器附接元件120基本包括第一部件160、第二部件162、連接部件164及固定部件166。導鏈器附接元件120與前撥鏈器10的導鏈器附接元件20相同，除了導鏈器附接元件120的第二部件162已被修改。這裡，第二部件162的寬度比導鏈器附接元件20的第二部件62的寬度窄。導鏈器附接元件120以與導鏈器附接元件20相同的方式來作用。In the second embodiment, the chain guide attachment element 120 basically includes a first part 160 , a second part 162 , a connecting part 164 and a fixing part 166 . The chain guide attachment element 120 is identical to the chain guide attachment element 20 of the front derailleur 10 except that the second part 162 of the chain guide attachment element 120 has been modified. Here, the width of the second part 162 is narrower than the width of the second part 62 of the chain guide attachment element 20 . The chain guide attachment element 120 functions in the same manner as the chain guide attachment element 20 .

現參考圖19，示出了根據第三實施例的前撥鏈器210。這裡，前撥鏈器210是電動前撥鏈器，而不是電纜操作型撥鏈器。鑑於第一實施例與第三實施例的相似之處，第三實施例的描述將集中於第三實施例的主要不同之處。Referring now to FIG. 19 , there is shown a front derailleur 210 according to a third embodiment. Here, the front derailleur 210 is an electric front derailleur, not a cable-operated type derailleur. In view of the similarities between the first embodiment and the third embodiment, the description of the third embodiment will focus on the main differences of the third embodiment.

前撥鏈器210包括基座構件212、導鏈器214及連桿總成216。基座構件212建構成安裝到自行車車架。導鏈器214建構成可相對於基座構件212移動。特別地，連桿總成216在縮回位置及伸展位置之間將導鏈器214可操作地耦接到基座構件212，以移動自行車鏈條。前撥鏈器210還包括在基座構件212上支撐的致動器217。這裡，致動器217具有可逆轉電動馬達217A，其可操作地連接到連桿總成216，以用於在縮回位置及伸展位置之間移動導鏈器214。The front derailleur 210 includes a base member 212 , a chain guide 214 and a linkage assembly 216 . The base member 212 is configured to be mounted to a bicycle frame. The chain guide 214 is configured to be movable relative to the base member 212 . In particular, linkage assembly 216 operably couples chain guide 214 to base member 212 between a retracted position and an extended position to move the bicycle chain. The front derailleur 210 also includes an actuator 217 supported on the base member 212 . Here, the actuator 217 has a reversible electric motor 217A operatively connected to the linkage assembly 216 for moving the chain guide 214 between the retracted position and the extended position.

導鏈器214包括內板250及外板252。內板250及外板252被建構成在其間形成導鏈槽254。這裡，內板250包括面向導鏈槽254的內表面250a。內板250還包括從內表面250a突出到導鏈槽254中的突出部件250b。內板250與上述的內板50相同，外板252與上述的外板52相同。因此，導鏈器214基本上具有與上述的導鏈器14相同的構造。The chain guide 214 includes an inner plate 250 and an outer plate 252 . The inner plate 250 and the outer plate 252 are configured to form a chain guide slot 254 therebetween. Here, the inner plate 250 includes an inner surface 250 a facing the chain guide groove 254 . The inner plate 250 also includes a protruding member 250b protruding from the inner surface 250a into the chain guide groove 254 . The inner panel 250 is the same as the aforementioned inner panel 50 , and the outer panel 252 is the same as the aforementioned outer panel 52 . Therefore, the chain guide 214 basically has the same configuration as the chain guide 14 described above.
