請參閱第1、2圖,所示者為本發明提供之健身裝置之換向曲柄模組,其包括有一連接件1及一曲柄桿件2。該連接件1設有一輪軸連接部11,其凹設有一嵌槽12,以供與健身裝置之轉動輪組的輪軸緊配合地嵌合固定。該輪軸連接部11之周緣沿徑向擴展有一凸緣13,且定義該凸緣13之頂面為一環面14,其中該環面14上設有複數個位於不同方位角之第一定位部15。於本實施例中,該第一定位部15為兩個設於該環面14上的凹槽,且兩凹槽彼此相距180度。於其他實施態樣中,該第一定位部15更可依使用需求設置三個以上的數量,並於該環面14上以相等的角度差距平均配置。Referring to Figures 1 and 2, there is shown a reversing crank module for the exercise device provided by the present invention, which includes a connecting member 1 and a crank member 2. The connecting member 1 is provided with an axle connecting portion 11 recessed with a slot 12 for fitting and fixing in close cooperation with the axle of the rotating wheel set of the exercise device. The periphery of the axle connecting portion 11 has a flange 13 extending in the radial direction, and the top surface of the flange 13 is defined as a toroidal surface 14, wherein the annular surface 14 is provided with a plurality of first positioning portions 15 at different azimuth angles. . In the embodiment, the first positioning portion 15 is two grooves disposed on the annular surface 14, and the two grooves are 180 degrees apart from each other. In other implementations, the first positioning portion 15 can be more than three in number according to the use requirement, and is evenly arranged on the toroid 14 with equal angular gaps.

另一方面,該曲柄桿件2為一長桿體,其一端設有一用以連接踏板之踏板連接部21,另一端設有一套筒部22。如第2、3圖所示,該套筒部22之一端凹設有一第一容槽221,另一端凹設有一第二容槽222,二者之間以一隔牆223相隔。該套筒部22於該第一容槽221之外設有一第二定位部23,其中於本實施例中,該第二定位部23為兩個可與前述凹槽嵌合之凸塊,且兩凸塊彼此相距180度。於該第一定位部15設置三個以上的實施態樣中,該第二定位部23亦將設置對應的數量。On the other hand, the crank member 2 is a long rod body having a pedal connecting portion 21 for connecting the pedal at one end and a sleeve portion 22 at the other end. As shown in the second and third figures, one end of the sleeve portion 22 is recessed with a first receiving groove 221, and the other end is recessed with a second receiving groove 222 separated by a partition wall 223. The sleeve portion 22 is provided with a second positioning portion 23 outside the first receiving groove 221, wherein in the embodiment, the second positioning portion 23 is two protrusions engageable with the groove, and The two bumps are 180 degrees apart from each other. In the three or more embodiments in which the first positioning portion 15 is provided, the second positioning portion 23 will also be provided with a corresponding number.

承上,該套筒部22以該第一容槽221套於該連接件1之外周,由於並非緊配合的設置,該套筒部22係可相對該連接件1沿一軸向L移動;同時,該套筒部22亦可相對該連接件1轉動,進而改變該曲柄桿件2相對該連接件1之方位角。上述該套筒部22相對該連接件1轉動時,該第二定位部23隨著移動,並在其位置對應於該第一定位部15之位置時,可隨著該套筒部22相對該連接件1的軸向移動而與該第一定位部15相嵌合,藉此使該套筒部22與該連接件1固定。The sleeve portion 22 is sleeved on the outer circumference of the connecting member 1 by the first receiving groove 221, and the sleeve portion 22 is movable relative to the connecting member 1 in an axial direction L because it is not tightly fitted; At the same time, the sleeve portion 22 can also rotate relative to the connecting member 1 to change the azimuth angle of the crank member 2 relative to the connecting member 1. When the sleeve portion 22 rotates relative to the connecting member 1, the second positioning portion 23 moves with the second positioning portion 23, and when the position thereof corresponds to the position of the first positioning portion 15, the sleeve portion 22 can be opposite to the sleeve portion 22 The axial movement of the connecting member 1 is engaged with the first positioning portion 15, whereby the sleeve portion 22 is fixed to the connecting member 1.

又該輪軸連接部11設有一鎖固於輪軸上之軸柱16,該軸柱16穿過該隔牆223伸入該第二容槽222,且穿出該套筒部22。該軸柱16設有一螺紋段161,並於末端螺設有一擋塊17,該擋塊17可藉由旋轉而沿該軸柱16產生位移。當該擋塊17移動至與該套筒部22相距有一間距D的位置時,該套筒部22即可在該間距D之範圍中軸向移動,以使該第一定位部15與該第二定位部23結合或脫離。Further, the axle connecting portion 11 is provided with a shaft post 16 locked to the axle, and the shaft pillar 16 extends through the partition wall 223 into the second pocket 222 and passes through the sleeve portion 22. The shaft post 16 is provided with a threaded section 161, and a stopper 17 is screwed at the end, and the stopper 17 can be displaced along the shaft post 16 by rotation. When the stopper 17 is moved to a position spaced apart from the sleeve portion 22 by a distance D, the sleeve portion 22 can be axially moved in the range of the distance D, so that the first positioning portion 15 and the first portion The two positioning portions 23 are joined or disengaged.

更進一步地,該軸柱16之外周套設有一彈簧18,該彈簧18位於該套筒部22與該擋塊17之間,其一端抵於該擋塊17,另一端則伸入該第二容槽222並抵於該隔牆223上,據此該彈簧18以該擋塊17為固定端,而常態地推抵該套筒部22。Further, the outer periphery of the shaft column 16 is sleeved with a spring 18 between the sleeve portion 22 and the stopper 17, one end of which abuts against the stopper 17 and the other end of which extends into the second portion. The pocket 222 is in contact with the partition wall 223, whereby the spring 18 is fixed to the sleeve portion 22 with the stopper 17 as a fixed end.

經由上述說明,可瞭解本發明將前述各構件組合為一換向曲柄模組,藉此可單獨購買此模組,用來改裝現有的健身裝置,使其轉動輪組的曲柄具有換向功能。如第4圖所示,將本發明以該輪軸連接部11固定於健身裝置之轉動輪組3的輪軸31上後,即可透過本發明的曲柄桿件2搭配轉動輪組3另一側的曲柄32操作轉動輪組3,藉此進行運動訓練。第4圖所示者係本發明的曲柄桿件2與轉動輪組3另一側的曲柄32呈反向的狀態,此狀態可供使用者之雙腳以一前一後的姿勢踩踏於踏板上進行運動。Through the above description, it can be understood that the present invention combines the foregoing components into a reversing crank module, whereby the module can be separately purchased for retrofitting an existing exercise device such that the crank of the rotating wheel set has a reversing function. As shown in FIG. 4, after the axle connecting portion 11 of the present invention is fixed to the axle 31 of the rotating wheel set 3 of the exercise device, the crank member 2 of the present invention can be used to match the other side of the rotating wheel set 3. The crank 32 operates the rotating wheel set 3, thereby performing exercise training. The figure shown in Fig. 4 is in a state in which the crank member 2 of the present invention is opposite to the crank 32 on the other side of the rotating wheel set 3, and this state allows the user's feet to step on the pedal in a front-rear posture. Exercise on the top.

而曲柄換向的過程如第5圖所示,首先將該套筒部22相對該連接件1軸向上拉,使該第二定位部23退出該第一定位部15,則解除該套筒部22與該連接件1之固定狀態,該套筒部22即可相對該連接件1轉動。該套筒部22轉動時,該第二定位部23隨著轉動,且該曲柄桿件2相對該輪軸31之方位角亦隨之改變,當該套筒部22轉動180度後,如第6圖所示,該曲柄桿件2的方位轉換為與轉動輪組3另一側的曲柄32呈同向的狀態,而該第二定位部23又再度與該第一定位部15在位置上相對應,而可推動該套筒部22軸向下移以使該第一定位部15與該第二定位部23相嵌合,藉此固定該套筒部22與該連接件1。此狀態可供使用者之雙腳以同樣在前的姿勢踩踏於踏板上進行運動,而健身裝置經由上述方式使本發明之曲柄桿件2進行換向後,使用者即可以不同的姿勢踩踏於踏板上進行運動,達到不同的訓練目的。As shown in FIG. 5, the crank portion 22 is first pulled up in the axial direction of the connecting member 1 to release the second positioning portion 23 from the first positioning portion 15, and the sleeve portion is released. The sleeve portion 22 is rotatable relative to the connector 1 in a fixed state with the connector 1. When the sleeve portion 22 rotates, the second positioning portion 23 rotates, and the azimuth angle of the crank member 2 relative to the axle 31 also changes. When the sleeve portion 22 is rotated 180 degrees, as in the sixth As shown, the orientation of the crank member 2 is converted to be in the same direction as the crank 32 on the other side of the rotating wheel set 3, and the second positioning portion 23 is again in position with the first positioning portion 15. Correspondingly, the sleeve portion 22 can be pushed axially downward to fit the first positioning portion 15 and the second positioning portion 23, thereby fixing the sleeve portion 22 and the connecting member 1. In this state, the user's feet can be stepped on the pedal in the same front position to perform the movement, and after the exercise device reverses the crank member 2 of the present invention in the above manner, the user can step on the pedal in different postures. Exercise on the ground for different training purposes.

此外,在操作曲柄換向完成後,可如第7圖所示地旋動該擋塊17,使其沿該軸柱16移動並與該套筒部22相抵,此時該套筒部22沒有可以軸向移動的空間,因而可避免該第二定位部23意外脫離該第一定位部15的情形,確保健身裝置可正常使用。Further, after the operation cranking is completed, the stopper 17 can be rotated as shown in FIG. 7 to move along the shaft post 16 and abut against the sleeve portion 22, at which time the sleeve portion 22 does not have The space can be moved axially, so that the second positioning portion 23 can be prevented from accidentally disengaging from the first positioning portion 15, and the fitness device can be used normally.

惟,以上實施例之揭示僅用以說明本發明,並非用以限制本發明,故舉凡等效元件之置換仍應隸屬本發明之範疇。However, the above description of the embodiments is merely illustrative of the invention and is not intended to limit the invention, and the replacement of equivalent elements is still within the scope of the invention.

綜上所述,可使熟知本項技藝者明瞭本發明確可達成前述目的,實已符合專利法之規定,爰依法提出申請。In summary, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives and is in accordance with the provisions of the Patent Law.
