Abstract
Description
本發明尤指僅須花費較少的力量即可驅動自行車行進之特殊技術領域。
The invention particularly refers to a particular technical field that can drive a bicycle to travel with less effort.
傳統自行車便如第一圖所示般，其包括有：
一車架(11)，其後方具有一後叉(111)，另於前端耦接有一前叉(112)，更在後叉(111)與前叉(112)之間設有一五通管(113)；
一後輪(12)，其係以一後輪軸(121)樞接於後叉(111)；
一樞接於前叉(112)之前輪(13)；
一樞接於五通管(113)之中天心軸(14)，該中天心軸(14)、後輪(12)及前輪(13)之中心軸線係呈彼此平行，且令中天心軸(14)兩端係突出五通管(113)；
一固置於中天心軸(14)之前鏈輪(15)；
一固置於後輪軸(121)一端緣之後鏈輪(16)；
一環繞於前鏈輪(15)及後鏈輪(16)之鏈條(17)；
兩曲柄(18A)(18B)，其一端係呈對稱的固設於中天心軸(14)兩端，且令兩曲柄(18A)(18B)呈間隔180度配置；以及
兩踏板(19A)(19B)，其係對稱的樞設於兩曲柄(18A)(18B)自由端，用以提供吾人雙腳踩動，以便力矩作用兩曲柄(18A)(18B)而帶動前鏈輪(15)自轉，藉由鏈條(17)、後鏈輪(16)之動力傳遞而帶動後輪(12)，如此即可驅使自行車行進。
可是，該兩曲柄(18A)(18B)在提供吾人踩踏時，其施力所產生的力矩亦為一定，如此一來，騎乘該等自行車相當耗費體力，不足以提供省力操作。
基於現有自行車省力不足處，便有M376509「具省力作用之自行車」因應產生，可是，該專利前案至少有以下缺點：
1.不利DIY組裝；因導引盤須固置於車架上，其須以點焊機將導引盤焊接固置於車架，或者，對車架施以鑽孔加工，以便將導引盤螺鎖固置於車架，由是觀之，該等焊接或鑽孔作業，實在不利吾人DIY組裝。
2.製造成本高；其導引盤及其蛋形軌道須以CNC銑削為之，其整體製造成本所費不貲。
3.結構易損壞；其內曲柄與外曲柄在空間限制下，兩者滑合面積相當有限，所以會有應力集中之易損壞問題。再則，此導桿自由端沿蛋形軌道限位滑動時，係屬一種局部摩擦受力，其使用一段時日便會有鬆動或干涉之缺點。
職是，本發明人基於上述專利前案之缺點，乃以多年的專業經驗與心得，經不斷構思、創研，乃研發出更具進步性之本發明。
The traditional bicycle is as shown in the first picture, which includes:
A frame (11) has a rear fork (111) at the rear, a front fork (112) coupled to the front end, and a five-way tube between the rear fork (111) and the front fork (112). (113);
a rear wheel (12), which is pivotally connected to the rear fork (111) by a rear axle (121);
a pivotal connection to the front fork (112) front wheel (13);
A central axis (14) pivotally connected to the five-way pipe (113), the central axes of the central mandrel (14), the rear wheel (12) and the front wheel (13) are parallel to each other, and the central axis is 14) Both ends are protruding five-way pipe (113);
a sprocket (15) placed in front of the Zhongtian mandrel (14);
a sprocket (16) fixed to one end of the rear axle (121);
a chain (17) surrounding the front sprocket (15) and the rear sprocket (16);
Two cranks (18A) (18B), one end of which is symmetrically fixed at both ends of the center mandrel (14), and the two cranks (18A) (18B) are arranged at intervals of 180 degrees; and two pedals (19A) ( 19B), which is symmetrically pivoted at the free ends of the two cranks (18A) (18B) to provide us with two feet to move, so that the torque acts on the two cranks (18A) (18B) and drives the front sprocket (15) to rotate. The rear wheel (12) is driven by the power transmission of the chain (17) and the rear sprocket (16), thus driving the bicycle to travel.
However, when the two cranks (18A) (18B) provide us with the pedaling, the torque generated by the force is also constant, so that riding the bicycles is quite labor-intensive and insufficient to provide labor-saving operation.
Based on the lack of labor in the existing bicycles, there is a M376509 "saving bicycle", but the patent has at least the following shortcomings:
1. Unfavorable DIY assembly; since the guide disc must be fixed on the frame, it must be welded to the frame by a spot welder, or the frame can be drilled for guiding The screw is fixed on the frame. It is obvious that these welding or drilling operations are not suitable for our DIY assembly.
2. High manufacturing cost; its guide plate and its egg-shaped track must be CNC milling, and its overall manufacturing cost is not expensive.
3. The structure is easy to damage; under the space limitation of the inner crank and the outer crank, the sliding area of the two is quite limited, so there is a problem of easy concentration of stress concentration. Moreover, when the free end of the guide rod slides along the limit of the egg-shaped track, it is a kind of local frictional force, and it may have the disadvantage of loosening or interference for a period of time.
The inventor of the present invention has developed a more progressive invention based on the shortcomings of the above-mentioned patents, with years of professional experience and experience, through continuous conceiving and research.
本發明係提供一種自行車之省力裝置，其主要在自行車二曲柄自由端各安裝有一傳動桿，此傳動桿在前端與後端之間設有能耦接於曲柄之第一樞部，且令後端係位於自行車後輪外側，更於該後端之端面凹設有導引孔，而傳動桿前端則安裝有踏板；
另，於自行車之後輪軸兩端各固置有一輔支桿，此輔支桿係朝自行車後輪後方延伸，用以耦接有一導引桿，此導引桿係能對稱的與傳動桿之導引孔滑配，俾在雙腳踩動踏板時，傳動桿能以第一樞部作支點的擺動，而導引桿能沿導引孔伸縮，且可以第二、三樞部作支點的擺動因應，如此即可以使本發明踏板能產生如M376509專利前案所示般之省力操作模式。
但是，本發明較M376509專利前案確具有以下進步處：
1.具有可DIY組裝之優點；因本發明只是在現有自行車上另外安裝傳動桿、輔支桿及導引桿，其無須另外加工車架即可以完成，由是觀之，稍具有機械常識者，均可以輕易自行組裝。
2.製造成本低；本發明傳動桿、輔支桿及導引桿加工，其無須特別機械加工即可以完成，所以其整體製造成本遠較M376509專利前案更低。
3.實用性高；本發明曲柄、傳動桿、輔支桿、導引桿及後輪軸之整體配合係形成一拘束鏈結構，並使傳動桿在轉動時，令中天心軸及遠端之輔支桿能有效支持，所以本發明在運行時，遠較M376509專利前案更順暢及穩定，進而具有能長時間提供自行車省力操作使用之進步性。
The invention provides a labor-saving device for a bicycle, which is mainly provided with a transmission rod at a free end of the two cranks of the bicycle. The transmission rod is provided with a first pivot portion coupled between the front end and the rear end, and is configured to be The end is located outside the rear wheel of the bicycle, and the guiding hole is recessed on the end surface of the rear end, and the pedal is installed at the front end of the transmission rod;
In addition, an auxiliary strut is fixed at each end of the axle of the bicycle, and the auxiliary strut extends toward the rear of the rear wheel of the bicycle for coupling with a guiding rod, and the guiding rod is symmetrical with the guiding rod of the transmission rod The guide hole slides, when the pedals are stepped on the pedals, the transmission rod can swing with the first pivot as a fulcrum, and the guide rod can expand and contract along the guide hole, and the second and third pivots can be used as a pivot point In response to this, the pedal of the present invention can be produced in a labor-saving mode of operation as shown in the M376509 patent.
However, the present invention has the following advances over the M376509 patent case:
1. It has the advantages of DIY assembly; because the invention only installs the transmission rod, the auxiliary support rod and the guiding rod on the existing bicycle, it can be completed without separately processing the frame, and it is a matter of mechanical knowledge. , can be easily assembled by themselves.
2. The manufacturing cost is low; the transmission rod, the auxiliary strut and the guiding rod of the invention can be processed without special machining, so the overall manufacturing cost is much lower than that of the M376509 patent.
3. High practicability; the overall cooperation of the crank, the transmission rod, the auxiliary strut, the guiding rod and the rear axle forms a restraint chain structure, and when the transmission rod is rotated, the center shaft and the distal end are supplemented. The struts can be effectively supported, so the invention is far smoother and more stable than the M376509 patent before operation, and thus has the progressiveness of providing bicycles with labor-saving operation for a long time.
