Description

Two-way propelling type transmission mechanism for bicycle
BACKGROUND OF THE INVENTION
5 1. Field of the Invention:
The present invention relates to a transmission mechanism for bicycle and more particularly, to a two-way propelling type transmission mechanism for bicycle, which can be propelled either forwardly or backwardly to move the 10 bicycle, allowing the user to apply force to the pedals through different parts of the soles of the legs.
2. Description of the Related Art: A transmission mechanism for bicycle is known 15 comprising a driving axle, a gear cluster mounted on one end of the driving axle for synchronous rotation, two pedals, two cranks coupled between the two ends of the driving axle and the two pedals. When pedaling the pedals to rotate the cranks forwards, the gear cluster is rotated with the 20 driving axle to move the bicycle forwards. On the contrary, when pedaling the pedals to rotate the cranks backwards, the driving axle is rotated counter-clockwise without moving the gear cluster. Therefore, the driving axle runs idle when the user pedals the pedals backwardly. Thus, the user can propel 25 the pedals to move the bicycle forwards only applying a force through the front part (the toes) of the sole of each leg. The front part of the sole of each leg will become tired and painful soon when pedaling the pedals of the bicycle in this manner.

SUMMARY OF THE INVENTION
The present invention has been accomplished under the circumstances in view. It is one object of the present 2 invention to provide a two-way propelling type transmission mechanism for bicycle, which can be propelled either forwardly or backwardly to move the bicycle, allowing the user to apply force to the pedals through different parts of 5 the soles of the legs.
To achieve this and other objects of the present invention, a two-way propelling type transmission mechanism for bicycle comprises a driving axle, a first gear and a second gear mounted on the driving axle, a directional gear 10 mounted on the driving axle between the first and second gears, a transmission shaft, a first transmission gear mounted on one end of the transmission shaft and meshed with the first gear, a second transmission gear, a chain coupled between the second transmission gear and the second gear, 15 and a control line operable to pull the directional gear away from a series of clutch teeth at the first gear into engagement with a series of clutch teeth at the second gear so that pedaling the pedals to rotate cranks either forwardly or backwardly can drive the first gear to rotate a 20 gear cluster in moving the bicycle forwards subject to the control of the control line.

5 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1-4, a two-way propelling type transmission mechanism for bicycle in accordance with the present invention is shown comprising a casing 4 covered with a cover 5, a driving axle 1 rotatably supported in the 10 casing 4, two pedals 3 suspending outside the casing 4, two cranks 2 coupled between the two ends of the driving axle 1 and the two pedals 3, a directional gear 10 mounted on the driving axle 1 inside the casing 4, a first gear 11 mounted on the driving axle 1 in the casing 4 and disposed at one 15 side relative to the directional gear 10 and having a tubular gear shaft 12 and a series of clutch teeth 13 located on one end of the tubular gear shaft 12, a gear cluster 6 mounted on the other end of the tubular gear shaft 12 outside the casing 4 and remote from the series of clutch 20 teeth 13, a second gear 20 mounted on the driving axle 1 in the casing 4 and disposed at an opposite side relative to the directional gear 10 and having a series of clutch teeth 21 at its one side, a transmission axle 30 rotatably mounted in the casing 4 and arranged in a parallel manner relative 25 to the driving axle 1, a first transmission gear 31 fixedly mounted on one end of the transmission axle 30 and meshed with the first gear 11, a second transmission gear 32 fixedly mounted on the other end of the transmission axle 30, a chain 22 coupled between the second gear 20 and the 30 second transmission gear 32, a bearing ring 14 mounted on the directional gear 10, a pull spring 15 connected to the bearing ring 14 and imparting a pull force to the bearing ring 14 and the directional gear 10 to keep the directional 4 gear 10 in mesh with the series of clutch teeth 13 of the first gear 11, and a control line 16 connected to the bearing ring 14 and operable to pull the bearing ring 14 and the directional gear 10 away from the series of clutch teeth 5 13 of the first gear 11 into engagement with the series of clutch teeth 21 of the second gear 20.
The operation of the two-way propelling type transmission mechanism is described hereinafter.
When the user propels the pedals 3 forwardly, as 10 shown in FIG. 3, the cranks 2 are rotated forwards (clockwise), the directional gear 10 is meshed with the series of clutch teeth 13 of the first gear 11 and disengaged from the series of clutch teeth 21 of the second gear 20. At this time, the second gear 20 is immovable, and 15 the first gear 11 is rotated forwards (clockwise), causing the gear cluster 6 to be rotated with the tubular gear shaft 12 of the first gear 11 to move the bicycle forwards.
On the contrary, when pedaling the pedals 3 backwardly, as shown in FIG. 4, operate the control line 16 20 to pull the bearing ring 14 and the directional gear 10 away from the series of clutch teeth 13 of the first gear 11 into engagement with the series of clutch teeth 21 of the second gear 20. At this time, the driving axle 1 is rotated with the cranks 2 backwards (counter-clockwise). Because the 25 directional gear 10 is disengaged from the series of clutch teeth 13 of the first gear 11 and meshed with the series of clutch teeth 21 of the second gear 20 at this time, the second gear 20 is rotated with the directional gear 10 backwards (counter-clockwise) to move the chain 22, the 30 second transmission gear 32, the transmission axle 30, causing the first transmission gear 31 to rotate the first gear 11 forwards (clockwise), and therefore the gear cluster 5 6 is rotated with the tubular gear shaft 12 of the first gear 11 to move the bicycle forwards.
Thus, pedaling the pedals 3 to rotate the cranks 2 either forwardly or backwardly, the gear cluster 6 can be 5 rotated with the tubular gear shaft 12 of the first gear 11 to move the bicycle forwards, allowing the user to apply force to the pedals 3 through different parts of the soles of the legs.
Although a particular embodiment of the invention 10 has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
