1243783 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種機車之後腳踏板，特別是關於速克達 型機車之後腳踏板者。 【先前技術】 先前之機車，為了方便後座騎乘者置腳之舒適性，於機 車座塾下方車體之兩側分別設置一後腳踏板以供後座騎乘 者置腳之用。此種先前之機車之後腳踏板，如圖6之先前之 機車之後腳踏板分解圖所示，其後腳踏板100之構造，係以 螺栓105螺检5首先穿過連結部1〇3及踏板1〇2上之孔，接著 穿過套筒106同時穿過包圍套筒1〇6的螺旋彈簧1〇4，再穿過 踏板102及連結部1〇3上之孔，最後再以一栓1〇7加以穿插固 定’如此將踏板102連結固定於固定構件1〇1上。此種結構 長久以來由機車業界所沿用，然其雖可達到使機車後座騎 乘者便於置放雙腳之舒適性，但由於螺旋彈簧1〇4保持做動 而使踏板102向外彈開，因此停車時會佔用兩側過多的空 間，或於停車或牵車時因凸出的後腳踏板造成碰撞周圍物 件或人的腳部的情形發生，使用上相當地不方便。 為了解決上述之問題，中華民國第55313〇號新型專利公 告之「機車後腳踏板結構改良」中，提出了一種解決方案。 請參考圖7,圖7(a)係其後腳踏板結構之分解圖，圖八…係 其後腳踏板收折狀態時之剖面圖，圖7(c)係其後腳踏板彈開 狀態時之剖面圖。其係在定位元件131之處藉由一螺絲US 及一回復彈簧136嵌插一踏板132,使踏板132具有自動彈出 95814.doc 1243783 的功能。並利用彈性元件143抵頂於板體141相對的壁面， 以將滑塊142往前頂，使滑塊142的外側端頭由定位元件13 1 對應面的槽孔134伸入抵卡於踏板丨32的缺槽133，以令踏板 1 3 2被限制為貼靠於側車殼的收折狀態。 當騎乘者欲彈出踏板132時，係以腳踩壓按鈕151，使彈 性元件152被壓擠成收縮狀，而使按鈕151的底側端頭向下 移位。由於在按紐151的底側端頭設有斜面丨5 3，因此當斜 面153頂觸壓到滑塊142上方的斜面144時，滑塊M2即會向 内側位移，而使得其外側端頭由缺槽133退出，此時踏板132 即被回復彈簧136的彈力彈出成可置腳的狀態。 而當騎乘者欲收折踏板132時，隨著腳離開按鈕151，彈 性元件1 52之彈力可使按紐丨5 !回復原位，此時滑塊142的外 側端頭係抵頂於踏板132之缺槽133的弧面處，因此當以腳 將踏板132向側車殼推壓使踏板132接近侧車殼後，踏板132 之缺槽133會對齊滑塊142的外側端頭，使滑塊142的外側端 頭再度肷入踏板132的缺槽1 33中，使踏板132被限制為收折 狀態。 如上所述，此種先前之機車之後腳踏板，必須以腳部去 踩壓該驅動構件之按鈕，方能將踏板132彈開而使其彈出使 用。然而在面積狹窄的後腳踏板上設置的驅動機構的按鈕 1 5 1自然相當的小，後座騎乘者的腳部必須經過一番摸索方 月b踩壓到按鈕15丨，而且大部分的人所穿著的皮鞋或高跟 鞋，由於鞋底形成為高低差甚大的凹凸面，因此更加難以 順利地以鞋底順利地踩壓到按鈕丨5丨。此外，該後腳踏板通 95814.doc 1243783 常係配合機車車型的設計，設置於與置腳板與側車殼之間 附近形成的凹部空間内，因此當後座騎乘者欲以腳部踩壓 該微小之按鈕151時，會受到置腳板與側車殼之影響，而可 能難以取得最佳之腳部踩壓位置，以致增添踩壓動作的困 難性。 此外，上述構成中，必須具備按鈕151、彈性元件152、 及斜面153等構件，#可達成其作用，因&其構成複雜，成 本較高。而按鈕151下方的斜面153與滑塊142上方的斜面 144對位較為困難，且使用時間長久後，因彈簧鬆弛變形， 對位產生偏差，造成藉由踩壓使踏板132彈出的動作更為困 難。 ’、 【發明内容】 ’本發明係發明人針對先前機車之後腳踏板中所存在之上 述種種問題加以致力研發，而提出之一嶄新之解決方案 者。其目的在於提供一種機車之後腳踏板，其可以簡單的 構成，提供較大面積的觸壓部分，而使機車後座騎乘者可 迅速且容易地將後腳踏板收折或彈出，以達使用之便利性。

Description of the invention: [Technical field to which the invention belongs] The present invention relates to a rear pedal of a locomotive, especially to a rear pedal of a Scooter locomotive. [Previous technology] In the previous locomotive, in order to facilitate the comfort of the rear seat rider's feet, a rear foot pedal was provided on each side of the vehicle body below the seat of the locomotive for the rear seat rider's foot placement. Such a rear pedal of the previous locomotive is shown in the exploded view of the rear pedal of the previous locomotive, as shown in the exploded view of the previous pedal of the previous locomotive. Through the hole in 10, then through the sleeve 106 and through the coil spring 104 surrounding the sleeve 106, then through the hole in the pedal 102 and the connecting portion 103, and finally with a bolt 1 〇7 Penetrating and fixing 'In this way, the pedal 102 is connected and fixed to the fixing member 101. This structure has been used by the locomotive industry for a long time. Although it can achieve the comfort of locomotive rear seat riders to place their feet comfortably, the pedal 102 springs out because the coil spring 104 keeps acting. Therefore, when parking, it will take up too much space on both sides, or when bumping the surrounding objects or people's feet due to the protruding rear pedal when parking or driving, it is quite inconvenient to use. In order to solve the above-mentioned problems, a new type of solution is proposed in the "Improvement of the structure of the rear pedals of a locomotive" of the new patent publication No. 55313. Please refer to Figure 7, Figure 7 (a) is an exploded view of the rear pedal structure, Figure 8 is a cross-sectional view of the rear pedal when it is folded, and Figure 7 (c) is a cross-sectional view of its rear pedal when it is open. . It is inserted into a pedal 132 by a screw US and a return spring 136 at the positioning element 131, so that the pedal 132 has the function of automatically ejecting 95814.doc 1243783. The elastic element 143 is pressed against the opposite wall surface of the plate body 141 to push the slider 142 forward, so that the outer end of the slider 142 protrudes from the slot 134 on the corresponding surface of the positioning element 13 1 and engages the pedal 丨The notch 133 of 32 is to limit the pedal 1 3 2 to the folded state against the side shell. When the rider wants to eject the pedal 132, he presses the button 151 with his foot, so that the elastic element 152 is squeezed into a contracted shape, and the bottom end of the button 151 is displaced downward. Because the bottom end of the button 151 is provided with an inclined surface 5 3, when the inclined surface 153 presses against the inclined surface 144 above the slider 142, the slider M2 will be displaced inward, so that the outer end of the slider The notch 133 exits, and at this time, the pedal 132 is ejected into a foot-possible state by the elastic force of the return spring 136. When the rider wants to fold the pedal 132, as the foot leaves the button 151, the elastic force of the elastic element 1 52 can return the button 丨 5! To the original position. At this time, the outer end of the slider 142 is pressed against the pedal. At the curved surface of the slot 133 of 132, when the pedal 132 is pushed toward the side shell with the foot to bring the pedal 132 close to the side shell, the slot 133 of the pedal 132 will be aligned with the outer end of the slider 142, making the slide The outer end of the block 142 is again inserted into the slot 1 33 of the pedal 132, so that the pedal 132 is restricted to the folded state. As described above, after such a previous locomotive, the foot pedal must be used to depress the button of the driving member before the pedal 132 can be opened and used for ejection. However, the button 1 5 1 of the driving mechanism provided on the narrow foot pedal is naturally quite small. The foot of the rear seat rider must press the button b to press the button 15 丨, and most people The leather shoes or high-heeled shoes that are worn are more difficult to smoothly press the button 丨 5 丨 because the sole is formed as a concave-convex surface with a large height difference. In addition, the rear foot pedal pass 95814.doc 1243783 is usually designed in accordance with the locomotive model, and is set in the recessed space formed between the foot plate and the side shell, so when the rear seat rider wants to press the foot When the small button 151 is affected by the footrest and the side shell, it may be difficult to obtain the optimal pressing position of the foot, thereby increasing the difficulty of pressing. In addition, the above-mentioned structure must include members such as the button 151, the elastic element 152, and the beveled surface 153, and # can achieve its role, because its structure is complicated and its cost is high. The slanted surface 153 below the button 151 and the slanted surface 144 above the slider 142 are difficult to align, and after a long period of use, due to the looseness and deformation of the spring, the alignment deviates, making it more difficult to push the pedal 132 by pressing. . [Content of the invention] 'The present invention is an inventor who has devoted himself to the research and development of the above-mentioned problems in the pedals after the previous locomotive, and has proposed a brand-new solution.

According to the above configuration of the present invention, by accommodating at least a part of the folded-up pedal in the recessed portion formed on the side shell of the vehicle body, the folded-back rear pedal can not cause collision with surrounding objects or What happens to a person's feet. The invention in the scope of patent application No. 5 of the present invention is a locomotive, and has the same scope as the scope of patent application! To the rear pedal of any of the locomotive according to the fourth order. According to the above structure of the present invention, a locomotive having the effect of a rear pedal of a locomotive such as the one in the patent claims No. 4 to No. 4 can be obtained. [Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Please refer to FIGS. 1 to 3 first, FIG. ⑽ is a side view of a locomotive with a foot pedal 1 after the locomotive of the present invention, FIG. 2 is an enlarged view of the foot pedal 丨 of the locomotive of the present invention, and FIG. 3 is a locomotive of the present invention. Exploded view of the foot pedal. Fig. 1 shows a state in which the pedals of the present invention are arranged on a one-speed keda locomotive, which is in a folded state. Referring again to FIG. 2, an enlarged view of the pedal i. The foot pedal of the present invention includes a pedal 2 for placing a foot of a rear seat rider, for fixing the pedal 2 to the fixing member 3 on the vehicle body. The combination of the pedal 2 and the fixing member 3 is fixed by bolts 5. As shown in the exploded view of FIG. 3, the bolt 5 first passes through the connecting portion of the fixing member 3 ^ 95814.doc 1243783 and then through the hole 32 ' The hole η on the connecting end 21 of the pedal 2 passes through the sleeve 6 and passes through the coil spring * surrounding the sleeve 6 at the same time, then passes through the hole 22 at the connecting end η and the hole 32 on the connecting portion 31, and finally It is interspersed and fixed with-bolt. = In the above configuration, the coil spring 4 surrounding the sleeve 6 is set to be in an undeformed state when the pedal 2 is in an open state, and when the pedal 2 receives an external force, the bolt 5 is used as the shaft, and it is rotated toward the fixed member 3 and approached. , The spiral impeachment 4 can hold an elastic force in the direction of popping on the light 2, so that the pedal 2 continues to keep returning to the original position in the direction of ^ skin popping. On the connecting end 21 of the pedal 2, a fastening protrusion is fastened by screws. In contrast, a fastening member 8 is embedded in the connecting portion 31 of the fixing member 3, and a front end thereof is provided for fastening. The engaging opening μ for engaging the convex portion 7. Concave grooves are formed on the left and right sides of the fastening member 8. As shown in FIG. 3, the side surface of the groove 83 and the opposite side of the fastening end is formed into a gradually concave shape: by this-designing, the fastening is used After the member 8 is pushed in from the outside of the hole M of the fixing member 3 to the inside, the groove 81 of the fastening member 8 can be fitted and fixed to the hole 33. The fastening member 8 is designed so that when the pressure-receiving portion 82 is pushed, the opening of the button σ port 81 is performed in a slave stroke. When the pressure receiving part is pushed for the first time, its engaging opening 81 will perform a short stretch of the first stroke: after that, when the dust receiving part 82 is pushed for the second time, its engaging opening _ Enter a longer opening motion for the second stroke. With this design of the opening action of two strokes with different stroke lengths, the engaging opening W can be caught and released by the desired hooking member. 95814.doc -10- 1243783 Please refer to FIG. 4. FIG. 4 (a) and FIG. 4 (b) are schematic diagrams of the folded and springed state of the foot pedal 1 of the locomotive of the present invention. As shown in FIG. 4 (a), when the rider wants to retract the pedal 2 and, for example, presses the pedal 2 with a force that resists the spring force of the coil spring 4, the pedal 2 is rotated and fixed with the bolt 5 as an axis. After the member 3, the buckling projection 7 of the pedal 2 first pushes the buckle 0 port 8 1 of the buckling member 8 of the fixing member 3 into it. At this time, as described above, the buckling port 8 1 will be short In the opening action of the first stroke, after the rider stops exerting force, the pedal 2 and the engaging projection 7 are moved backwards. Since the engaging opening 81 is already closed, the hook-shaped front end of the engaging opening 81 will protrude to the engaging. The front end of the portion 7 is hooked, so that the protruding portion 7 for the buckle opening cannot exit the buckling opening 8 丨, and the pedal 2 is in a folded state. After that, when the rider of the rear seat wants to pop the pedal 2 for the purpose of setting the foot, it is the same as when the pedal 2 is retracted. For example, the foot is given a force that resists the spring force of the coil spring 4 times. When the pedal 2 is pushed, the pedal 2 is rotated about the screw inspection 5 as the axis, and the pressure-receiving portion 82 of the fastening member 8 is pushed slightly deeper, and the hook-shaped front end of the fastening opening is opened. After the rider stops applying force At this time, as described above, the fastening opening 81 will perform a longer opening movement of the second stroke. Therefore, the fastening opening 81 will be closed after the fastening protrusion 7 exits from the fastening opening 81. It will be hooked as before ', so that the front end of the fastening projection 7 will be released from the fastening σ8 of the fastening member 8. Then, the pedal 2 will be continuously applied by the coil spring 4 in the direction of springing. The elastic force acts, and the bolt 5 is rotated to the springing direction to return to the springing position. As described above, the structure of the foot pedal 丨 according to the present invention is not only simple in structure, low in cost, but also a rider. You can press the foot with a contactable area of ^ 95814.doc -11- 1243783 to make it buckle After the combined protrusion 7 is fastened to the fastening opening 8, the pedal 2 can be folded. The rider pushes the pedal with a large accessible area again with his feet to cause the pedal 2 to spring off from the side of the vehicle body. The buckle action is quite convenient and smooth, without the difficulty of stepping on the buttons with a relatively small accessible area or being hindered by other parts of the vehicle body as in the prior art, so the pedal cannot be quickly and smoothly ejected, or it must be very strong Stepping on the button can resist the problem of the elastic force of the spring that restricts the button. In addition, as shown in FIG. 3, after the present invention, the foot pedal 丨 preferably forms a pressing part on the surface where the pedal 2 is pressed. 9. The pressing portion 9 can be formed of a soft material such as tree moon or oak tree 4, which can make the rider feel more comfortable when pressing the pedal with his foot. An enlarged view of a cross-section of the line portion. As shown in FIG. 1, the present invention can form a recessed portion on the side shell of the vehicle body, and the pedal 2 can be at least partially accommodated in the recessed portion when folded. In this way, Makes the folded back foot pedal 1 It may happen that it collides with surrounding objects or people ’s feet.
