藉由本新型，能提供一種快拆裝置用螺母、以及使用該螺母之快拆裝置軸組件，達成不需要螺母終端的構造，而使螺母殼體的設計自由度增加。According to the present invention, it is possible to provide a nut for a quick release device and a quick release device shaft assembly using the nut, thereby achieving a structure in which a nut end is not required, and the design freedom of the nut case is increased.
第1圖是顯示組裝有本新型的快拆裝置用螺母的輪轂的一個例子的右側視圖。該輪轂，具有：習知的輪轂主體1、緊固軸3、與緊固軸3的一端螺合的快拆裝置用螺母20、以及與緊固軸3的另一端卡合的緊固槓桿2。並且在輪轂主體1的一端(第3圖右端)與快拆裝置用螺母20之間、以及輪轂主體1的另一端(第3圖左端)與緊固槓桿2之間，安裝有螺旋狀彈簧4、5。藉由緊固槓桿2、緊固軸3、螺旋狀彈簧4、5、以及快拆裝置用螺母20，形成快拆裝置軸組件。Fig. 1 is a right side view showing an example of a hub in which a nut for a quick release device of the present invention is assembled. The hub includes a conventional hub body 1, a fastening shaft 3, a quick release device nut 20 that is screwed to one end of the fastening shaft 3, and a fastening lever 2 that engages with the other end of the fastening shaft 3. . Further, a spiral spring 4 is attached between one end of the hub body 1 (the right end of FIG. 3) and the quick release device nut 20, and between the other end of the hub body 1 (the left end of FIG. 3) and the fastening lever 2. , 5. The quick release device shaft assembly is formed by the fastening lever 2, the fastening shaft 3, the helical springs 4, 5, and the quick release device nut 20.
第2圖是快拆裝置用螺母20的放大圖。快拆裝置用螺母20，是由：螺母主體11、螺母殼體22、及摩擦部13所構成。螺母主體11，在位於凸緣部11a的鋸齒部11b，與自行車的後終端、前終端等的框架抵接。藉由螺母主體11與輪轂殼罩1夾住框架，則可旋轉地將自行車的輪轂軸支承、緊固。Fig. 2 is an enlarged view of the nut 20 for the quick release device. The quick release device nut 20 is composed of a nut main body 11, a nut housing 22, and a friction portion 13. The nut main body 11 is in contact with the frame of the rear end of the bicycle, the front end, or the like, in the serration portion 11b of the flange portion 11a. When the nut body 11 and the hub shell 1 are sandwiched by the frame, the hub of the bicycle is rotatably supported and fastened.
螺母殼體22，一般是藉由樹脂一體形成，如第3圖所示，包含有：壓入固定部22a、保持部22c、卡止部22d、以及握持面22e。壓入固定部22a，具有鋸齒部22b。以下使用第2圖及第3圖，來說明螺母殼體22的構造。The nut case 22 is generally integrally formed of a resin, and as shown in Fig. 3, includes a press-fit fixing portion 22a, a holding portion 22c, a locking portion 22d, and a grip surface 22e. The press-fit fixing portion 22a has a serration portion 22b. The structure of the nut case 22 will be described below using Figs. 2 and 3 .
保持部22c，是用來保持後述的摩擦部13所設置的空隙。壓入固定部22a，是用來將螺母主體11壓入固定的孔 部。在壓入固定部22a，是藉由壓入方式來將螺母殼體22與螺母主體11連結。壓入固定部22a，當將摩擦部13安裝於保持部22c時，也應用作為讓摩擦部13通過的孔部。因此，壓入固定部22a的直徑，稍大於保持部22c的直徑。鋸齒部22b，與在螺母主體11上設置的鋸齒部卡合，來防止：被壓入固定的螺母殼體22相對於螺母主體11旋轉。卡止部22d，用來限制：後述的摩擦部13朝緊固軸3的輪轂軸方向的移動。握持面22e，是當使用者使快拆裝置用螺母20旋轉時，讓使用者握持的面部。The holding portion 22c is a space for holding the friction portion 13 to be described later. The press-fit fixing portion 22a is for pressing the nut main body 11 into the fixed hole unit. In the press-fit fixing portion 22a, the nut case 22 and the nut main body 11 are coupled by press fitting. The press-fit fixing portion 22a is also applied as a hole portion through which the friction portion 13 passes when the friction portion 13 is attached to the holding portion 22c. Therefore, the diameter of the press-fit fixing portion 22a is slightly larger than the diameter of the holding portion 22c. The serration portion 22b is engaged with the serration portion provided on the nut main body 11 to prevent the nut housing 22 that is press-fitted from rotating relative to the nut main body 11. The locking portion 22d is for restricting movement of the friction portion 13 to be described later in the direction of the hub axis of the fastening shaft 3. The grip surface 22e is a face that the user holds when the user rotates the quick release device with the nut 20.
摩擦部13，是由彈性體所構成的O型環，與螺母殼體22為不同個體，設置於保持部22c，在其與緊固軸3之間施加摩擦阻力，具有防止緊固軸3鬆開的功能。如第2圖，藉由作成讓螺母主體11與螺母殼體22的卡止部22d夾住摩擦部13，來限制：摩擦部13朝輪轂軸方向的移動。The friction portion 13 is an O-ring composed of an elastic body, and is different from the nut housing 22, and is provided in the holding portion 22c, and applies frictional resistance between the friction shaft 3 and the fastening shaft 3 to prevent the fastening shaft 3 from loosening. Open function. As shown in Fig. 2, by causing the nut body 11 and the locking portion 22d of the nut housing 22 to sandwich the friction portion 13, the movement of the friction portion 13 in the hub axis direction is restricted.
本新型，不像習知技術是將螺母終端14壓入，而是藉由螺母主體11與螺母殼體22的卡止部22d，來限制：摩擦部13朝緊固軸3的輪轂軸方向移動。因此，即使螺母殼體22的厚度較薄也可以，能夠增加螺母殼體22的設計的自由度。According to the prior art, the nut terminal 14 is pressed in, but the nut body 11 and the locking portion 22d of the nut housing 22 are used to restrict the friction portion 13 from moving toward the hub axis of the fastening shaft 3. . Therefore, even if the thickness of the nut case 22 is thin, the degree of freedom in designing the nut case 22 can be increased.
並且本新型，由於不需要螺母終端，所以能夠減少快拆裝置用螺母的零件數量，能使快拆裝置用螺母的成本減少，進而讓使用該螺母的快拆裝置軸組件的製造成本減少。Further, in the present invention, since the nut terminal is not required, the number of parts of the nut for the quick release device can be reduced, the cost of the nut for the quick release device can be reduced, and the manufacturing cost of the quick release device shaft assembly using the nut can be reduced.
在本新型，輪轂殼罩1、緊固槓桿2、緊固軸3、螺旋狀彈簧4、5的形狀或材質，只要能達成輪轂功能及快拆裝置功能，任何形狀、材質都可以。而快拆裝置軸組件，也可沒有螺旋狀彈簧4、5。In the present invention, the shape or material of the hub shell 1, the fastening lever 2, the fastening shaft 3, and the spiral springs 4, 5 can be any shape or material as long as the hub function and the quick release device function can be achieved. The quick-release device shaft assembly may also have no helical springs 4, 5.
在螺母殼體22，握持面22e、及鋸齒部22b的形狀，任意形狀都可以。壓入固定部22a，也可不包含鋸齒部22b。The shape of the nut case 22, the grip surface 22e, and the serration portion 22b may be any shape. The press-fit fixing portion 22a may not include the serration portion 22b.
並且螺母主體11的形狀，只要是能將自行車的框架卡止，能將緊固軸3旋入的形狀，除了在壓入固定部22a被固定的部位之外，任何形狀都可以。例如，凸緣部11a為任意大小、形狀。螺母主體11、螺母殼體22、及摩擦部13的材質，只要能達成其功能，任何材質都可以。Further, the shape of the nut main body 11 may be any shape as long as it can lock the frame of the bicycle and can screw the fastening shaft 3, and any shape other than the portion where the press-fit fixing portion 22a is fixed. For example, the flange portion 11a is of any size and shape. The material of the nut body 11, the nut case 22, and the friction portion 13 can be any material as long as the function can be achieved.
