Description
本發明係有關於一種自行車鏈條，特別係指將鏈條之外鏈片及外鏈片之連接孔均縮小以保持強度之鏈條。 The present invention relates to a bicycle chain, and more particularly to a chain that reduces the connection holes of the outer and outer links of the chain to maintain strength.
目前自行車已變成不可或缺之生活用品，其可使用於娛樂、運動、交通或競賽等，為使自行車可配合使用於各種場合，所以對自行車之功能設計越來越講究，其中一種為變速功能，現代自行車變速裝置之設計趨勢朝向變速段數的增加，為增加變速段數而增設越來越多大小不依的鏈盤，舉例說，自行車之後鏈盤從以往的九個鏈盤組增加到十個、十一個甚至十二個鏈盤組，但是，為保持自行車之重心，鏈盤組之設計無法沿自行車車軸無止境的延伸，所以當鏈盤數量越作越多時，就必須將鏈盤與鏈盤之間的空隙縮小，如九個鏈盤組之各鏈盤間空隙為6.4mm、十個鏈盤組之各鏈盤間空隙為5.9mm、十一個鏈盤組之各鏈盤間空隙為5.5mm、十二個鏈盤組之各鏈盤間空隙為5.0mm，由前述數據即可得知鏈盤數量越多，其各鏈盤間之空隙越小，所以與鏈盤配合之鏈條，若大小保持不變，將會產生變速過程不順暢或無法變速之問題，且容易發出噪音，故鏈條為了與鏈盤組搭配，使其變速過 程順暢，勢必在形態上必須跟著改變縮小，但是，基於鏈盤之設計並未改變，所以不管鏈條之形態或大小如何改變，皆需可與鏈盤搭配。 At present, bicycles have become indispensable daily necessities, which can be used for entertainment, sports, transportation or competition. In order to make bicycles suitable for various occasions, the function design of bicycles is becoming more and more important, one of which is a shifting function. The design trend of modern bicycle shifting devices is toward the increase of the number of shifting sections. In order to increase the number of shifting sections, more and more chain discs of different sizes are added. For example, after the bicycle, the chain discs are increased from the previous nine chain disc sets to ten. One, eleven or even twelve chain groups, but in order to maintain the center of gravity of the bicycle, the design of the chain group cannot extend endlessly along the bicycle axle, so when the number of chains is increased, the chain must be The gap between the disc and the chain plate is reduced, for example, the gap between the respective chain discs of the nine chain disc groups is 6.4 mm, the gap between the respective chain discs of the ten chain disc groups is 5.9 mm, and the chains of the eleven chain disc groups The gap between the discs is 5.5mm, and the gap between the sprockets of the twelve chain disc groups is 5.0mm. From the above data, the more the number of the sprockets, the smaller the gap between the sprockets, and the sprockets. Match the chain, if big Remains unchanged, the process will not produce a smooth shifting or not shifting of the problem, and easy to make noise in order to match it with the chain wheel of the chain group, transmission through it Cheng Shunchang is bound to change and shrink in shape. However, the design based on the chain has not changed, so no matter how the shape or size of the chain changes, it needs to be matched with the chain.
再者，鏈條為帶動自行車運行之主要零組件，於帶動過程中，需承受拉力、側向力及與鏈盤之摩擦力等負荷，所以無限制的縮小鏈條之形態，則會將鏈條之強度削弱，不僅無法達成820kg以上之抗拉強度標準，也會讓鏈條之壽命簡短，如中華民國發明專利公告第I324574號『自行車鏈條』之專利案，包含有兩個外側鏈節板件的外側鏈節、由兩個內側鏈節板件形成的內側鏈節、及將相鄰的鏈節板件連接在一起的鏈節銷。鏈節板件形成為輔助在鏈盤之間移動的鏈條可平滑地換檔。外側鏈節板件具有形狀不同的外側鏈節周邊邊緣。外側鏈節板件之一具有面向外部表面，此面向外部表面具有在第一端部部份處沿著外側鏈節板件的外側鏈節周邊邊緣的一區段延伸的第一去角外部邊緣部份、及相對於第一端部部份沿著縱向軸線的徑向尺寸具有減小的徑向尺寸的第一面積減小部份。內側鏈節板件具有有不同的極小寬度的中央連接部份。 In addition, the chain is the main component that drives the bicycle to run. During the driving process, it needs to bear the load such as tension, lateral force and friction with the chain plate. Therefore, if the chain shape is reduced without limit, the chain strength will be Weakening, not only can not achieve the tensile strength standard of more than 820kg, but also make the life of the chain short, such as the Patent of the Republic of China Invention Patent No. I324574 "Bicycle Chain", including the outer chain of two outer link plates An inner link formed by two inner link plates and a link pin connecting adjacent link plates together. The link plates are formed to assist in smooth shifting of the chain moving between the links. The outer link plate member has outer edge link peripheral edges of different shapes. One of the outer link plates has an outwardly facing surface having a first chamfered outer edge extending along a section of the outer link peripheral edge of the outer link plate at the first end portion And a first area reduction portion having a reduced radial dimension relative to a radial dimension of the first end portion along the longitudinal axis. The inner link plate member has a central connecting portion having a different minimum width.
上述前案I324574主要是將外側鏈節板件縮小，使得在鏈盤間移動之鏈條可順暢的變速換檔，但是，前案將外側鏈節板件面積縮小或厚度變薄時，其連接孔之孔徑不變，而使得外側鏈節板件之面積縮減而讓強度減弱，進而影響到鏈條整體之強度。 The above-mentioned former case I324574 mainly reduces the outer link plate member, so that the chain moving between the links can smoothly shift gears, but when the front case reduces the area of the outer link plate or the thickness is thin, the connecting hole thereof The aperture is constant, and the area of the outer link plate is reduced to weaken the strength, thereby affecting the overall strength of the chain.
爰此，本發明提供一種鏈條，所述之鏈條係配合自行車鏈盤而設計，而將鏈條之外側鏈片之面積縮小或厚度變薄，以幫助鏈條於鏈盤上變速順暢，並同時將外側鏈片之連接孔之孔徑也縮小，使得鏈條可適用於高段數變速之鏈盤上，且鏈條之強度亦足夠，而改善習知鏈條在於將外側鏈片面積縮小或厚度變薄之後，強度便不足之困擾。 Accordingly, the present invention provides a chain designed to fit a bicycle chain plate, and the area of the side chain outside the chain is reduced or thinned to help the chain shift smoothly on the chain, and at the same time the outer side The aperture of the connecting hole of the chain is also reduced, so that the chain can be applied to the high-speed shifting chain, and the strength of the chain is sufficient, and the conventional chain is improved in that the outer chain area is reduced or the thickness is thinned, and the strength is improved. It is not enough trouble.
另外，所述之鏈條即使外側鏈片縮小，但鏈條之內側鏈片組並未變更設計，使得鏈條可與習知鏈盤配合作動，而不用製造特殊鏈盤來配合鏈條。 In addition, even if the outer chain is reduced, the inner chain piece of the chain is not changed in design, so that the chain can cooperate with the conventional chain without making a special chain to match the chain.

6.如第十八圖所示，為該第一外側鏈片(1)或第二外側鏈片(2)之第一連接部(11)(21)之面積(A)等於第二連接部(12)(22)之面積(A)，且其外周緣(B)呈大圓形狀連接小圓形狀，要說明的是，第一連接孔(111)(211)之橫向軸線(D)向上至外周緣(B)之面積(A1)小於由第一連接孔(111)(211)之橫向軸線(D)向下至外周緣(B)之面積(A2)；而第二連接孔(121)(221)之橫向軸線(D)向上至外周緣(B)之面積(A1)大 於由第二連接孔(121)(221)之橫向軸線(D)向下至外周緣(B)之面積(A2)，又第一連接孔(111)(211)之孔徑等於第二連接孔(121)(221)之孔徑，且均較習知鏈片之孔徑小，所以第一連接部(11)(21)及第二連接部(12)(22)之面積(A)雖然較習知鏈片小，但其孔徑亦跟著縮小，故不影響強度，進而保持鏈條整體強度。 6. As shown in Fig. 18, the area (A) of the first connecting portion (11) (21) of the first outer chain piece (1) or the second outer chain piece (2) is equal to the second connecting portion. (12) The area (A) of (22), and the outer circumference (B) is connected in a large circle shape in a large circle shape, and it is to be noted that the lateral axis (D) of the first connection hole (111) (211) is upward. The area (A1) of the outer circumference (B) is smaller than the area (A2) from the lateral axis (D) of the first connection hole (111) (211) down to the outer circumference (B); and the second connection hole (121) (221) The lateral axis (D) is large up to the outer circumference (B) (A1) In the area (A2) from the lateral axis (D) of the second connection hole (121) (221) down to the outer circumference (B), the aperture of the first connection hole (111) (211) is equal to the second connection hole. (121) The aperture of (221) is smaller than the aperture of the conventional link, so the area (A) of the first connecting portion (11) (21) and the second connecting portion (12) (22) is smaller than the conventional chain However, its pore size is also reduced, so it does not affect the strength, and thus maintain the overall strength of the chain.
此外，上述之第一外側鏈片(1)及第二外側鏈片(2)之第一連接部(11)(21)及第二連接部(12)(22)不管以何種形態呈現，於該第一連接部(11)(21)及第二連接部(12)(22)分別設置有至少一去角部(13)(23)，用以幫助鏈條於鏈盤上可順利換檔，並降低換檔時所產生之噪音。 In addition, the first connecting portion (11) (21) and the second connecting portion (12) (22) of the first outer chain piece (1) and the second outer chain piece (2) are not in any form. The first connecting portion (11) (21) and the second connecting portion (12) (22) are respectively provided with at least one chamfering portion (13) (23) for helping the chain to smoothly shift on the chain plate. And reduce the noise generated when shifting.
值得一提的是，如第十九圖、第二十圖及第二十一圖所示，由於將第一外側鏈片(1)及第二外側鏈片(2)之第一連接部(11)(21)或第二連接部(12)(22)之面積(A)縮小，所以當鏈條於鏈盤上換檔時，與鏈盤之鏈齒接觸面較小，而有機會造成鏈條左右偏而導致換檔不順利，故可於各該去角部(13)(23)延伸出一翼片(14)(24)，利用該翼片(14)(24)增加鏈條與鏈齒之接觸面積，使得鏈條換檔後，可被限制於鏈齒內而不左右偏，而提昇鏈條之穩定性。 It is worth mentioning that, as shown in the nineteenth, twentieth and twenty-first figures, the first connecting portion of the first outer chain piece (1) and the second outer chain piece (2) is 11) (21) or the area (A) of the second connecting portion (12) (22) is reduced, so when the chain is shifted on the chain, the contact surface with the sprocket of the chain is small, and there is a chance to cause the chain The left and right biases cause the shift to be unsmooth, so a fin (14) (24) can be extended from each of the corner portions (13) (23), and the chain and the chain teeth are added by the fins (14) (24). The contact area allows the chain to be limited to the inside of the chain without shifting the left and right sides, thereby improving the stability of the chain.
請再參閱第二十二圖、第二十三圖及第二十四圖，由於將第一外側鏈片(1)及第二外側鏈片(2)之第一連接部(11)(21)或第二連接部(12)(22)之面積(A)縮小，所以會導致鏈條之弧形變形率較大，故可於該第一外側鏈片(1)及第 二外側鏈片(2)之第一連接部(11)(21)及第二連接部(12)(22)之外周緣(B)分別設有一凸出部(15)(25)，進而縮小該鏈條之弧形變形率，以提昇鏈條之穩定性。 Please refer to the 22nd, 23rd, and 24th drawings, respectively, because the first connecting portion (11) of the first outer chain piece (1) and the second outer chain piece (2) (21) ) or the area (A) of the second connecting portion (12) (22) is reduced, so that the arc deformation rate of the chain is large, so that the first outer chain (1) and the first The first connecting portion (11) (21) of the two outer chain pieces (2) and the outer peripheral edge (B) of the second connecting portion (12) (22) are respectively provided with a protruding portion (15) (25), thereby reducing The arc deformation rate of the chain to improve the stability of the chain.
