[新型欲解決的課題][New problem to be solved]

專利文獻1的煞車操作裝置，煞車操作部僅朝煞車的操作方向擺動。在具備有電動變速用的變速操作部的專利文獻2的煞車裝置，煞車操作部也僅朝煞車的操作方向擺動。因此當自行車轉倒而其衝擊施加於煞車操作部時，煞車操作部可能會受損。In the brake operating device of Patent Document 1, the brake operating portion swings only in the operating direction of the brake. In the brake device of Patent Document 2 including the shift operating portion for electric shifting, the brake operating portion swings only in the operating direction of the brake. Therefore, when the bicycle is turned down and its impact is applied to the brake operating portion, the brake operating portion may be damaged.

本新型的課題，在可安裝於人力驅動車的車把的煞車操作裝置，可防止人力驅動車轉倒時的煞車操作構件的損傷。 [用以解決課題的手段]The problem of the present invention is to prevent damage to the brake operating member when the human-powered vehicle is turned over in the brake operating device that can be attached to the handlebar of the human-powered vehicle.

The chain 30 is engaged with the front sprocket 26 and a plurality of rear sprocket wheels 28.

後撥鏈器32r，因應於設置在前煞車操作裝置20f的變速操作部34的操作，將嚙合於複數的後鏈輪28的鏈條30切換，來變更自行車100的變速比。在本實施方式的自行車100未設置前撥鏈器。The rear derailleur 32r changes the gear ratio of the bicycle 100 by switching the chain 30 engaged with the plurality of rear sprockets 28 in response to the operation of the shift operating portion 34 provided in the front brake operating device 20f. The front derailleur is not provided in the bicycle 100 of the present embodiment.

前煞車操作裝置20f，安裝於車把桿17的彎曲部17a。前煞車操作裝置20f，包含將前輪12進行煞車操作的槓桿構件36。槓桿構件36，可連同變速操作部34一起朝前後方向及左右方向擺動。前煞車操作裝置20f，經由煞車纜線40f連結到將前輪12進行制動的前煞車裝置38f。前煞車裝置38f，因應於槓桿構件36的操作來將前輪12制動。前煞車操作裝置20f及變速操作部34的構造，是與習知相同的構造所以省略詳細說明。The front brake operating device 20f is attached to the curved portion 17a of the handlebar 17 . The front brake operating device 20f includes a lever member 36 that performs a braking operation on the front wheel 12. The lever member 36 is swingable together with the shift operating portion 34 in the front-rear direction and the left-right direction. The front brake operating device 20f is coupled to the front brake device 38f that brakes the front wheel 12 via the brake cable 40f. The front brake device 38f brakes the front wheel 12 in response to the operation of the lever member 36. The structure of the front brake operating device 20f and the shift operating portion 34 is the same as the conventional structure, and detailed description thereof will be omitted.

後煞車操作裝置20r，安裝於車把桿17的彎曲部17b。後煞車操作裝置20r，經由煞車纜線40r連結到將後輪14進行制動的後煞車裝置38r。後煞車操作裝置20r，如第2圖及第3圖所示，包含：托架41、基構件42、槓桿構件43、支承構件44、摩擦構件45、調整構件46。The rear brake operating device 20r is attached to the curved portion 17b of the handlebar 17 . The rear brake operating device 20r is coupled to the rear brake device 38r that brakes the rear wheel 14 via the brake cable 40r. As shown in FIGS. 2 and 3, the rear brake operating device 20r includes a bracket 41, a base member 42, a lever member 43, a support member 44, a friction member 45, and an adjustment member 46.

托架41，如第2圖所示，具有：固定部41a、握持部41b、第1軸41c。托架41，可固定於車把部16，且藉由固定部41a可裝卸地固定於車把桿17的彎曲部17b。握持部41b，是藉由騎乘者握持的部分，設置在托架41的上部。第1軸41c，在本實施方式，是朝左右方向延伸。As shown in Fig. 2, the bracket 41 has a fixing portion 41a, a grip portion 41b, and a first shaft 41c. The bracket 41 is fixed to the handle portion 16, and is detachably fixed to the curved portion 17b of the handlebar 17 by the fixing portion 41a. The grip portion 41b is provided on the upper portion of the bracket 41 by a portion held by the rider. In the present embodiment, the first shaft 41c extends in the left-right direction.

基構件42配置在托架41的內部。基構件42，可繞第1軸41c的軸周圍擺動地連結於托架41。而且基構件42連結於煞車纜線40r。基構件42具有：基部42a、一對側板部42b。在基部42a，固定有朝與第1軸41c不同方向延伸的第2軸48。第2軸48，在本實施方式，是朝前後方向延伸。一對側板部42b，從基部42a的兩端朝後方延伸，第1軸41c朝左右方向貫穿一對側板部42b。The base member 42 is disposed inside the bracket 41. The base member 42 is swingably coupled to the bracket 41 around the axis of the first shaft 41c. Further, the base member 42 is coupled to the brake cable 40r. The base member 42 has a base portion 42a and a pair of side plate portions 42b. A second shaft 48 that extends in a direction different from the first shaft 41c is fixed to the base portion 42a. The second shaft 48 extends in the front-rear direction in the present embodiment. The pair of side plate portions 42b extend rearward from both ends of the base portion 42a, and the first shaft 41c penetrates the pair of side plate portions 42b in the left-right direction.

槓桿構件43，朝上下方向延伸且其上部收容於托架41的內部。槓桿構件43，經由第2軸48連結於基構件42，且可繞第1軸41c的軸周圍擺動。槓桿構件43，藉由繞第1軸41c的軸周圍擺動而可進行煞車操作。詳細來說，槓桿構件43，在第1軸41c的軸周圍可朝前後方向擺動。當使槓桿構件43朝前後方向擺動時，基構件42會與槓桿構件43連動而繞第1軸41c的軸周圍擺動。藉此，拉伸煞車纜線40r，藉由後煞車裝置38r將後輪14制動。槓桿構件43，藉由未圖示的螺旋線圈彈簧被朝前方彈壓。The lever member 43 extends in the vertical direction and the upper portion thereof is housed inside the bracket 41. The lever member 43 is coupled to the base member 42 via the second shaft 48 and is swingable around the axis of the first shaft 41c. The lever member 43 can be braked by swinging around the axis of the first shaft 41c. Specifically, the lever member 43 is swingable in the front-rear direction around the axis of the first shaft 41c. When the lever member 43 is swung in the front-rear direction, the base member 42 is oscillated around the axis of the first shaft 41c in conjunction with the lever member 43. Thereby, the brake cable 40r is stretched, and the rear wheel 14 is braked by the rear brake device 38r. The lever member 43 is biased forward by a spiral coil spring (not shown).

槓桿構件43可繞第2軸48的軸周圍擺動。詳細來說，槓桿構件43，在第2軸的軸周圍可朝左右方向擺動。槓桿構件43，藉由托架41限制第2軸48的軸周圍的擺動範圍。具體來說，槓桿構件43，藉由托架41限制其朝向左側的擺動。The lever member 43 is swingable around the axis of the second shaft 48. Specifically, the lever member 43 is swingable in the left-right direction around the axis of the second shaft. The lever member 43 restricts the swing range around the shaft of the second shaft 48 by the bracket 41. Specifically, the lever member 43 restricts its swing toward the left side by the bracket 41.

支承構件44包含：第2軸48、單向離合器49。第2軸48具有：軸主體部48a、公螺紋部48b。軸主體部48a，其剖面為非圓形且朝前後方向貫穿基構件42的基部42a。公螺紋部48b設置於軸主體部48a的兩端。支承構件44，藉由與公螺紋部48b螺合的螺母構件50，不能旋轉地固定於基構件42的基部42a。The support member 44 includes a second shaft 48 and a one-way clutch 49. The second shaft 48 has a shaft main body portion 48a and a male screw portion 48b. The shaft main body portion 48a has a non-circular cross section and penetrates the base portion 42a of the base member 42 in the front-rear direction. The male screw portion 48b is provided at both ends of the shaft main body portion 48a. The support member 44 is non-rotatably fixed to the base portion 42a of the base member 42 by the nut member 50 screwed to the male screw portion 48b.

單向離合器49安裝於第2軸48的軸主體部48a。單向離合器49，如第3圖所示，包含：內輪49a、外輪49b、複數的傳遞構件49c、保持構件49d、複數的彈壓構件49e。The one-way clutch 49 is attached to the shaft main body portion 48a of the second shaft 48. As shown in Fig. 3, the one-way clutch 49 includes an inner ring 49a, an outer ring 49b, a plurality of transmission members 49c, a holding member 49d, and a plurality of elastic members 49e.

內輪49a為圓筒狀，不能旋轉地安裝於第2軸48。也就是說，內輪49a相對於基構件42不能旋轉。在內輪49a的外周面設置有：其內徑沿著周方向變化的複數的凸輪面49f。The inner ring 49a has a cylindrical shape and is rotatably attached to the second shaft 48. That is, the inner wheel 49a cannot rotate relative to the base member 42. The outer peripheral surface of the inner ring 49a is provided with a plurality of cam faces 49f whose inner diameter changes along the circumferential direction.

外輪49b，為圓筒狀，且在內輪49a的外周側可繞第2軸48的軸周圍旋轉。The outer ring 49b has a cylindrical shape, and is rotatable around the axis of the second shaft 48 on the outer peripheral side of the inner ring 49a.

傳遞構件49c為圓柱形狀且朝與第2軸48相同方向延伸。傳遞構件49c，配置於內輪49a與外輪49b之間且可移動於：在第3圖以實線所示的傳遞位置、與在第3圖以鏈線所示的非傳遞位置之間。傳遞構件49c，僅將外輪49b的一方向的旋轉傳遞到第2軸48。The transmission member 49c has a cylindrical shape and extends in the same direction as the second shaft 48. The transmission member 49c is disposed between the inner ring 49a and the outer ring 49b and is movable between a transfer position indicated by a solid line in FIG. 3 and a non-transfer position indicated by a chain line in FIG. The transmission member 49c transmits only one rotation of the outer ring 49b to the second shaft 48.

詳細來說，當傳遞構件49c位在傳遞位置時，也就是在第3圖外輪49b朝順時鐘方向旋轉時，傳遞構件49c咬入於內輪49a的外周面與外輪49b的內周面之間。結果，將外輪49b的旋轉經由內輪49a傳遞到第2軸48。換言之，禁止外輪49b的順時鐘方向的旋轉。 　　另一方面，當傳遞構件49c位在非傳遞位置時，也就是當外輪49b朝逆時鐘方向旋轉時，傳遞構件49c朝凸輪面49f移動。藉此，在內輪49a的外周面與外輪49b的內周面之間讓傳遞構件49c成為自由旋轉狀態。結果，不將外輪49b的旋轉傳遞到內輪49a。換言之，外輪49b可朝逆時鐘方向旋轉。In detail, when the transmitting member 49c is in the transmitting position, that is, when the outer wheel 49b of the third figure is rotated in the clockwise direction, the transmitting member 49c bites between the outer peripheral surface of the inner ring 49a and the inner peripheral surface of the outer ring 49b. . As a result, the rotation of the outer ring 49b is transmitted to the second shaft 48 via the inner ring 49a. In other words, the rotation of the outer wheel 49b in the clockwise direction is prohibited. On the other hand, when the transmitting member 49c is in the non-transfer position, that is, when the outer ring 49b is rotated in the counterclockwise direction, the transmitting member 49c is moved toward the cam surface 49f. Thereby, the transmission member 49c is freely rotated between the outer circumferential surface of the inner ring 49a and the inner circumferential surface of the outer ring 49b. As a result, the rotation of the outer wheel 49b is not transmitted to the inner ring 49a. In other words, the outer wheel 49b can be rotated in the counterclockwise direction.

保持構件49d在周方向隔著間隔保持著傳遞構件49c。保持構件49d固定於基構件42的基部42a。The holding member 49d holds the transmission member 49c at intervals in the circumferential direction. The holding member 49d is fixed to the base portion 42a of the base member 42.

彈壓構件49e將傳遞構件49c朝向傳遞位置側彈壓。彈壓構件49e藉由保持構件49d在周方向隔著間隔而支承。The biasing member 49e biases the transmission member 49c toward the transfer position side. The elastic member 49e is supported by the holding member 49d at intervals in the circumferential direction.

摩擦構件45是以樹脂或金屬等的材料形成。摩擦構件45是可摩擦卡合地被支承構件44支承。摩擦構件45，當預定以上的荷重作用於槓桿構件43時，與槓桿構件43同步相對於第2軸48相對旋轉。The friction member 45 is formed of a material such as resin or metal. The friction member 45 is supported by the support member 44 in a frictionally engageable manner. When the predetermined weight or more is applied to the lever member 43, the friction member 45 relatively rotates with respect to the second shaft 48 in synchronization with the lever member 43.

摩擦構件45包含：摩擦部45a、一對延伸部45b。摩擦部45a，當從前後方向觀察時為大致C字型，設置成與外輪49b的外周面接觸。摩擦部45a，可相對旋轉地與外輪49b摩擦卡合。詳細來說如上述，在第3圖，禁止外輪49b的順時鐘方向的旋轉。因此，例如，在第3圖的順時鐘方向，當外輪49b與摩擦部45a之間的摩擦力以上的荷重作用於槓桿構件時，摩擦構件45相對於外輪49b朝順時鐘方向旋轉。The friction member 45 includes a friction portion 45a and a pair of extension portions 45b. The friction portion 45a is substantially C-shaped when viewed from the front-rear direction, and is provided in contact with the outer circumferential surface of the outer ring 49b. The friction portion 45a is frictionally engaged with the outer ring 49b in a relatively rotatable manner. More specifically, as described above, in Fig. 3, the rotation of the outer ring 49b in the clockwise direction is prohibited. Therefore, for example, in the clockwise direction of FIG. 3, when the load of the frictional force between the outer ring 49b and the friction portion 45a acts on the lever member, the friction member 45 rotates in the clockwise direction with respect to the outer ring 49b.

一對延伸部45b，互相隔著間隙相對向且從摩擦部45a的兩端朝與槓桿構件43相同方向延伸。一對延伸部45b，配置在槓桿構件43的內周部，且設置成可與槓桿構件43一體移動。The pair of extending portions 45b are opposed to each other with a gap therebetween and extend from the both ends of the friction portion 45a in the same direction as the lever member 43. The pair of extending portions 45b are disposed on the inner peripheral portion of the lever member 43, and are provided to be movable integrally with the lever member 43.

調整構件46，設置用來調整外輪49b與摩擦構件45之間的摩擦力。調整構件46，例如是以槓桿構件43支承的螺紋構件，可從左右方向按壓一對延伸部45b。例如當要使外輪49b與摩擦構件45之間的摩擦力增加時，將調整構件46朝接近一對延伸部45b的方向旋入。藉此按壓一對延伸部45b，讓摩擦部45a按壓外輪49b的按壓力變大，則外輪49b與摩擦部45a之間的摩擦力會變大。這裡藉由調整構件46可容易調整外輪49b與摩擦構件45之間的摩擦力。The adjustment member 46 is provided to adjust the frictional force between the outer wheel 49b and the friction member 45. The adjustment member 46 is, for example, a screw member supported by the lever member 43, and the pair of extension portions 45b can be pressed from the left and right directions. For example, when the frictional force between the outer ring 49b and the friction member 45 is to be increased, the adjustment member 46 is screwed in a direction approaching the pair of extending portions 45b. By pressing the pair of extending portions 45b and increasing the pressing force of the friction portion 45a against the outer ring 49b, the frictional force between the outer ring 49b and the friction portion 45a is increased. Here, the frictional force between the outer ring 49b and the friction member 45 can be easily adjusted by the adjustment member 46.

在上述構造的後煞車操作裝置20r，當預定以上的荷重作用於槓桿構件43時，也就是當單向離合器49的外輪49b與摩擦構件45的摩擦部45a之間的摩擦力以上的荷重作用於槓桿構件43時，槓桿構件43與摩擦構件同步而相對於第2軸相對旋轉。具體來說，在第3圖，槓桿構件43連同摩擦構件45一起朝左側擺動。藉此，例如當自行車100轉倒時且槓桿構件43受到衝擊時，槓桿構件43朝自行車100的內側擺動，所以能防止後煞車操作裝置20r損傷。槓桿構件43，藉由單向離合器49僅限制一方向的旋轉，所以即使在因為衝擊讓槓桿構件擺動的情況，也能容易使槓桿構件43回到第3圖所示的原本位置。In the above-described rear brake operating device 20r, when a predetermined load or more is applied to the lever member 43, that is, a load greater than a frictional force between the outer ring 49b of the one-way clutch 49 and the friction portion 45a of the friction member 45 acts on In the lever member 43, the lever member 43 rotates relative to the second shaft in synchronization with the friction member. Specifically, in FIG. 3, the lever member 43 is swung toward the left side together with the friction member 45. Thereby, for example, when the bicycle 100 is turned down and the lever member 43 is subjected to an impact, the lever member 43 is swung toward the inner side of the bicycle 100, so that the rear brake operating device 20r can be prevented from being damaged. Since the lever member 43 restricts only one direction of rotation by the one-way clutch 49, the lever member 43 can be easily returned to the original position shown in Fig. 3 even when the lever member is swung by the impact.

[其他實施方式] 　　本新型並不限定於以上的實施方式，在未脫離本新型的範圍可進行各種變形或修正。[Other Embodiments] The present invention is not limited to the above embodiments, and various modifications and changes can be made without departing from the scope of the invention.

在上述實施方式，支承構件44包含單向離合器49，使摩擦構件45與單向離合器49的外輪49b摩擦卡合，而支承構件44不一定需要包含單向離合器49。例如，也可使支承構件44的第2軸48的外周面與摩擦構件45摩擦卡合。在該情況，第2軸48的軸主體部48a其剖面為圓形較佳。In the above embodiment, the support member 44 includes the one-way clutch 49, and the friction member 45 is frictionally engaged with the outer ring 49b of the one-way clutch 49, and the support member 44 does not necessarily need to include the one-way clutch 49. For example, the outer circumferential surface of the second shaft 48 of the support member 44 may be frictionally engaged with the friction member 45. In this case, it is preferable that the shaft main body portion 48a of the second shaft 48 has a circular cross section.

在上述實施方式，單向離合器49，雖然包含有設置有凸輪面49f的內輪49a，而不一定需要設置內輪49a。例如也可在第2軸48的外周面設置凸輪面49f。傳遞構件49c或凸輪面49f等的形狀不限定於上述實施方式。In the above embodiment, the one-way clutch 49 includes the inner ring 49a provided with the cam surface 49f, and it is not necessary to provide the inner ring 49a. For example, a cam surface 49f may be provided on the outer circumferential surface of the second shaft 48. The shape of the transmission member 49c or the cam surface 49f is not limited to the above embodiment.

後煞車操作裝置20r的構造，也可連結成經由煞車油等的流體來使後煞車裝置38r作動。例如後煞車操作裝置20r的構造也可具備有：缸體、可移動於缸體內的活塞、及流體可導通地與缸體連結的容器。在該情況，也可因應於槓桿構件36、43的動作讓活塞活動於缸體內，讓流體的壓力傳遞到後煞車裝置38r。例如後煞車裝置38r也可是碟煞裝置。The structure of the rear brake operating device 20r may be connected to activate the rear brake device 38r via a fluid such as brake oil. For example, the structure of the rear brake operating device 20r may include a cylinder, a piston movable in the cylinder, and a container in which the fluid is electrically connected to the cylinder. In this case, the piston may be moved into the cylinder in response to the action of the lever members 36, 43 to transfer the pressure of the fluid to the rear brake device 38r. For example, the rear brake device 38r may also be a disc brake device.

後煞車操作裝置20r的構造，也可適用於在槓桿構件36、43設置有電動變速用的操作部的煞車操作裝置。例如在前煞車操作裝置20f未在槓桿構件36設置變速操作部34的情況，也可將本新型適用於前煞車操作裝置20f。在該情況，前煞車操作裝置20f，作成與後煞車操作裝置20r為鏡像關係。The structure of the rear brake operating device 20r can also be applied to a brake operating device in which the lever members 36 and 43 are provided with an operation portion for electric shifting. For example, in the case where the front brake operating device 20f is not provided with the shift operating portion 34 in the lever member 36, the present invention can be applied to the front brake operating device 20f. In this case, the front brake operating device 20f is formed in a mirror image relationship with the rear brake operating device 20r.
