Description

Rear derailleur for bicycle

本設計所應用的物品為自行車後變速器，通常安裝於自行車後叉端上，配合變速操作以撥動鏈條，繞掛到大小不同的齒輪上。The article used in this design is a bicycle rear derailleur, which is usually installed on the rear fork end of the bicycle, and cooperates with the shifting operation to toggle the chain and wind it on gears of different sizes.

本設計自行車後變速器的特徵如各圖式所示，主要特徵為：一導輪架以及與該導輪架連結的一連結裝置，該連結裝置大致上呈長方體，中間部分呈中空並設有彈簧。該連結裝置在與導輪架相對的一端，透過一托架而可安裝於自行車後叉端上。如後視圖所示，該導輪架之內側板件之下端上緣呈彎曲形狀，如前視圖所示，該導輪架之外側板件，其兩端具有中空部份，如右側視圖所示，在該內側板件與該外側板件的兩端側面之間，上方裝設有導向導輪，下方裝設有張力導輪。The characteristics of the bicycle rear derailleur of this design are shown in the drawings. The main features are: a guide wheel frame and a connecting device connected to the guide wheel frame. The connecting device is roughly rectangular, and the middle part is hollow and provided with springs. . The connecting device is at the end opposite to the guide wheel frame and can be installed on the rear fork end of the bicycle through a bracket. As shown in the rear view, the upper edge of the lower end of the inner plate of the guide wheel frame is curved. As shown in the front view, the outer side plate of the guide wheel frame has hollow parts at both ends, as shown in the right view. , Between the inner panel and the outer panel at both ends of the side, a guide wheel is installed above, and a tension guide wheel is installed below.

另外，如立體圖、前視圖及俯視圖所示，前述連結裝置在前述導輪架側的一端與前述中間部分樞接，前述連結裝置在前述托架側的一端則凸設有裝設端子的部份。如後視圖所示，前述托架整體大致呈凹狀且其兩端形成有圓形狀。如立體圖及前視圖所示，前述連結裝置的前表面形成有凹下部。In addition, as shown in the perspective view, the front view, and the plan view, the connecting device is pivotally connected to the intermediate part at one end of the guide wheel frame side, and the end of the connecting device at the bracket side is projected with a terminal installation part . As shown in the rear view, the bracket is generally concave as a whole and rounded at both ends. As shown in the perspective view and the front view, a concave portion is formed on the front surface of the aforementioned connecting device.

本設計整體外觀新穎、具創作性，至少具有上述的創作特點。The overall appearance of this design is novel and creative, with at least the above-mentioned creative characteristics.
