M299119 八、新型說明: 【新型所屬之技術領域】 本創作係為一種自行車踏板及曲柄裝置,尤指一種改 變曲柄與踏板間接合部位之結合方式,而增強曲柄與踏板 間的結合效果。 【先前技術】 如第6圖所示,為習用之自行車踏板及曲柄裝置,其 係於一具有内螺紋孔6 1之曲柄6内先行螺合一螺紋套筒 6 2,並於曲柄6内所螺合之螺紋套筒6 2之前端再螺合 一螺帽套6 3,以增加鎖合力量及螺旋鎖緊限位住,之後, 再將一凸伸有一外螺紋桿7 1之踏板7鎖入螺紋套筒6 2 孔徑的内螺紋6 1中,予以完成曲柄6與踏板7的組合。 因此,習用之曲柄6與踏板7間組合的方式,其係利 用普通、平面之内螺紋孔與具外螺紋段之螺桿所具有相互 配合鎖緊之原理。然而,經騎乘衝撞後,螺紋孔與螺桿間 的鎖緊效果亦會受到震動影響,而使曲柄6與踏板7間發 生彼此鬆動的情形,因而引起踏板7需要時常再與曲柄6 相互鎖緊的不便,再者,於長期使用之後,震動亦會造成 整體之鎖合力下降,外螺紋桿7 1的螺紋、螺紋套筒6 2 的螺紋、曲柄6之内螺紋6 1均會發生損耗變形及脫牙等 不良之後遺現象。故,上述曲柄6與踏板7的結合構造實 在有加以改良之必要。 【新型内容】 本創作之主要目的,在於解決上述的問題而提供一種 5M299119 VIII. New description: [New technical field] This creation is a bicycle pedal and crank device, especially a combination of changing the joint between the crank and the pedal, and enhancing the joint effect between the crank and the pedal. [Prior Art] As shown in Fig. 6, a conventional bicycle pedal and crank device is screwed into a threaded sleeve 6 2 in a crank 6 having an internally threaded hole 61, and is placed in the crank 6 A threaded sleeve 6 2 is screwed to a nut sleeve 6 3 at the front end to increase the locking force and the screw locking limit, and then the pedal 7 of the externally threaded rod 7 1 is locked. The combination of the crank 6 and the pedal 7 is completed in the internal thread 61 of the bore of the threaded sleeve 6 2 . Therefore, the conventional method of combining the crank 6 with the pedal 7 utilizes the principle that the common, flat internal threaded hole and the screw having the externally threaded portion have a mutual locking function. However, after the ride is hit, the locking effect between the threaded hole and the screw is also affected by the vibration, and the crank 6 and the pedal 7 are loosened with each other, thereby causing the pedal 7 to be locked with the crank 6 from time to time. Inconvenience, in addition, after long-term use, the vibration will also cause the overall locking force to decrease, and the thread of the externally threaded rod 7 1 , the thread of the threaded sleeve 6 2 , and the internal thread 6 1 of the crank 6 will be deformed and deformed. Defects such as tooth removal. Therefore, the combination of the crank 6 and the pedal 7 is necessary to be improved.

The connecting rod is further matched with the crank: For the face and the external thread segment, when the pedal is connected to the through hole at the bottom end of the lever lock, the slope between the two is called the tension force and the supporting force formed by the inclination, and the effective elimination of the user riding the collision The resulting crank and the pedal move between each other 'and the effect of not loose. For the purpose of the foregoing, the present invention includes: a crank and a pedal, the crank has a joint at the bottom end, and the joint has a through hole penetrating the crank, and the through hole has a tapered shape . "The through hole has a small diameter portion and a large diameter portion, and (4) a continuous slope formed by the small diameter portion and the diameter portion connecting the large diameter portion to gradually extend outward and expand, and the small diameter portion is formed There is an internal thread section. And the pedal is outwardly convexly provided with a connecting rod, the connecting # has a small connecting portion and a large connecting portion, and the connecting portion of the large connecting portion and the pedal portion gradually extend outward to the small portion to reduce the small connecting portion And forming a continuous bevel with an arc produced in the large diameter portion; wherein the small connecting portion has an externally threaded portion, and the externally threaded portion is screwed into the inner thread of the small diameter portion . The above and other objects and advantages of the present invention will become more apparent from the detailed description of the embodiments of the invention described herein. Of course, this creation is allowed to differ on some parts or arrangements of parts, but the selected examples are given in this manual, and the construction is shown in the drawings. . ^ ^ [Embodiment] 6 M299119 Please refer to Fig. 1 to Fig. 2, which shows the structure of the embodiment selected for this creation. This is for illustrative purposes only and is not applicable to patent applications. The limit. The bicycle pedal and crank device of this embodiment includes a crank 1 and a pedal 2. The bottom end of the crank 1 has a joint portion 1 1 having a through hole 12 extending through the crank, and the through hole 12 has a tapered shape. The through hole 1 2 has a small diameter portion 1 2 1 and a large diameter portion 1 2 2, and the connection between the small diameter portion 1 2 1 and the large diameter portion 1 2 2 is increased toward the large diameter portion. Extending outwardly to form a curved continuous slope, and the small diameter portion 1 2 1 is provided with an internal thread segment 1 2 3 . The pedal 2 is outwardly convexly provided with a connecting rod 2 1 . The connecting rod 2 1 has a small connecting portion 2 1 1 and a large connecting portion 2 1 2, and the connecting portion 2 1 2 and the 6-foot pedal 2 are connected to each other. The small connecting section 2 1 1 gradually extends outwardly by the lower connecting section 2 1 1 and forms a continuous inclined plane which is curved and matched with the large diameter part 1 2 2; wherein the small connecting section 2 1 1 is further provided with an external thread segment 2 1 3 which can be screwed to the inner thread segment 1 2 3 of the small diameter portion 1 2 1 . As shown in Fig. 3, when the connecting rod 2 1 of the pedal 2 is locked into the through hole 1 2 of the engaging portion 1 1 of the crank 1, the small connecting portion 2 1 1 of the connecting rod 2 1 is screwed to the engaging portion 1 1 In the small-diameter portion 1 2 1 , the large connecting portion 2 1 2 of the connecting rod 2 1 is fitted into the large-diameter portion 1 2 2 of the joint portion 1 1 , and the inclined surface on the large connecting portion 2 1 2 is engaged with The inclined faces in the large diameter portion 1 2 2 7 M299119 of the portion 1 1 are in contact with each other, and when the pedal 2 is stepped on, the two kinds of faces will rub against each other, and the pedal 2 can be effectively locked to the joint portion 1 of the crank handle 1 1 on. Of course, there are still many examples of this creation, only the details change. Please refer to FIG. 4, which is a second embodiment of the present invention. The difference is that the large diameter portion 1 2 2 of the through hole 1 2 and the large connecting portion 2 if of the connecting rod 2 i are from the small diameter portion i 2丄 The connection with the large-diameter part 22 gradually extends outward toward the large diameter 22 to form a non-arc and smooth continuous fringe. And the connecting portion of the large connecting portion 2 1 2 and the pedal 2 gradually extends outward to the small connecting portion 2 1 1 to reduce the small connecting portion 2, and has a curvature, smooth and fits the large diameter portion 1 2 2 continuous faces. The structure of the second embodiment can still achieve the same effects as the first embodiment. Therefore, the crank of the creation and the pedal are both =: r aperture is a cone with a bevel and an internal thread segment = two - a connecting rod, and the connecting rod has a threaded section with a crank phase hole, when the pedal is connected with the lever The bottom end of the crank of the human hand goes to ^, and the slope between the sides is effective due to the lock tension cup R formed by the slope. The situation is that the crank and the pedal are loosened when the user rides the collision, and the situation is not achieved. Any loose effect. The disclosure of the embodiments is intended to illustrate the present invention and is not intended to be used in the present invention. The text is more or more special - the replacement of the pieces should still be subordinated to the above, so that those skilled in the art can understand that the 8 M299119 of this creation can achieve the above objectives, and it has already met the requirements of the Patent Law.爰 Make a special application.
