    摘要： To reduce the load alternately imposed on the rider's legs when the pedals are stepped and to use the muscle of the entire legs in a well balanced manner, thereby naturally returning the pedals to the initial position of the stepping operation without forming an unnatural bending state of each leg at the returning track of the pedal. A crank mechanism for a bicycle comprises a main crank (9), a follower crank (12), and a connecting lever (15) disposed between free ends of the cranks (9, 12), a second fixed fulcrum shaft (11) of the follower crank (12) being arranged at a location obliquely upward and backward of a first fixed fulcrum shaft (8) of the main crank (9), the follower crank (12) being extended downward beyond a line (L2) connecting the first and second fixed fulcrum shafts (8), (11) from the second fixed fulcrum shaft (11) such that a second free fulcrum shaft (11) at its free end is swung below the line (L2) connecting the first and second fixed fulcrum shafts (8, 11), a pedal (16) being attached to a projection end (17) in the vicinity of a first free fulcrum shaft (13) of the lever (15) and arranged in the vicinity of the free end of the main crank (9), the pedal (16) being rotated along a non-circular track (T) passing through the first and second fixed fulcrum shafts (8 and 11), and the first fixed fulcrum shaft (8) being located at an internal area of the track (T).

    摘要： Disclosed are an elliptical chainring capable of fine-angle variation, and a crankset of a bicycle comprising the same. The crankset of a bicycle according to the first embodiment of the present invention, comprises: a crank shaft; an asymmetric elliptical chainring which is fitted and fixed in the crank shaft, which has a plurality of first to fourth crank arm fixing holes formed at predetermined spaces, and which has a plurality of first fine-adjustment holes and plurality of second fine-adjustment holes formed on the top and bottom thereof; a first adaptor arranged on the top of the plurality of first to fourth crank arm fixing holes, the plurality of first fine-adjustment holes, and the plurality of second fine-adjustment holes of the asymmetric elliptical chainring so as to support the asymmetric elliptical chainring; a second adaptor arranged on the top of the fifth and sixth crank arm fixing holes and a plurality of third fine-adjustment holes of the first adaptor so as to support the first adaptor; a crank arm; and a plurality of chainring bolts selectively and respectively fixed in the plurality of first fine-adjustment holes and plurality of second adjustment holes. A worker may finely adjust the angle between the asymmetric elliptical chainring and the crank arm by changing the positions of the plurality of chainring bolts ( Fig. 1 ).

    摘要： A pedaling correction device for a bicycle capable of objectively detecting the state of pedaling and assisting the detection so that the training of pedaling technique can be performed according to an accurate theory, wherein cranks having pedals mounted at the tips thereof are installed on the center axis of the device so that a crank gear can be rotated according to the rotation of the cranks, the state of the pedaling of a user is monitored, the shape of the crank gear is deformed so that, when the cranks reach positions where the user must increase forces applied to the pedals, the vertical diameter of the crank gear can be increased and, when the cranks reach positions where the user must release forces applied to the pedals, the vertical diameter of the crank gear can be reduced, whereby the correction of habit of pedaling can be assisted by using such a crank gear.

    摘要： Manually driven mechanisms such as manually driven vehicles or machines imitating such vehicles, for example, bicycles, wheel chairs, boats, manually driven air planes and training machines. Manually driven mechanism units comprising rotary bodies (1, 100) consisting of sprockets and support bodies (2, 200) consisting of sprockets, provided in pairs and disposed one above the other, and chains (3, 300) passed therearound, are disposed laterally, the right and left rotary bodies (1, 100) being fixed on a drive shaft (15), and a loaded chain ring (6) is attached on the drive shaft (15) and between the rotary body (1) and the rotary body (100). Suppressing means comprising free cranks (10, 1000) and arms (11, 1100) ensure that the shafts of pedals (4, 400) are constantly held vertical with respect to the moving planes of the individual chains. The period in which the force transmitted from the feet to the pedals is effectively converted to torque is prolonged.

    摘要： There is disclosed a mechanism adapted to produce a plurality of different motions of a member affording a point for application of a force comprising: fixed disc means held in a fixed orientation; and at least one moveable disc means adapted to rotate around its origin and around the origin of the fixed disc means under the influence of the applied force; in which: the ratio of the radius of the fixed disc means to the radius of the moveable disc means is 2:1; the position of the point which the force is applied to is radially variable relative to the origin of the moveable disc means; and the moveable disc means is in communication with the fixed disc means so that rotation of the moveable disc means around the origin of the fixed disc means at a frequency f causes rotation of the moveable disc means at a frequency of 2f.
