The moving section 343 is pushed by the spring 341, such that the engaging portion 344 will be protruded out of the assembling opening 326. The shape and size of the engaging portion 344 are corresponding to that of the first and second locking holes 314, 315, such that the engaging portion 344 can pass through the first and second locking holes 314, 315, and the moving section 343 cannot pass through the first and second locking holes 314, 315. When the assembling opening 326 of the pivoting rack 32 is opposite the first locking hole 314 or the second locking hole 315 of the positioning rack 31, the engaging portion 344 of the engaging member 342 will be locked in the first locking hole 314 or the second locking hole 315.
The above-mentioned descriptions are the features of the bicycle saddle structure of the present invention, and the structure of the nose-shaped saddle is shown in FIGS. 2-5 and 11-12. The top surface 21 of the nose portion 20 is located at the same level as the top surface 111 of the saddle portion 11, so as to form the saddle with the nose portion 20, such that the rider can sit on the saddle portion 11 with his/her feet clamp both sides of the nose portion 20 as shown in FIG. 2. The center distance A between the elastic portions 122 is specially designed to be 8 to 15 cm, which can meet the requirements of the riders of different ages. In addition, the height B of each elastic portion 122 is 1 to 3 cm, which can meet the requirements of the riders with different body weights and support the rider by the best elasticity.
Since the saddle body 10 is provided with two elastic supporting bodies 12, the elastic supporting bodies 12 can hold the rider's hips when the rider sits on the saddle body 10 and can absorb bumps on the road when riding, so as to improve the riding comfort.
Referring to FIGS. 2-4 and 11-13, the assembling opening 326 of the pivoting rack 32 is opposite the first locking hole 314 of the positioning rack 31, and the moving section 343 of the engaging member 342 is pushed by the spring 341, such that the engaging portion 344 of the engaging member 342 will be locked in the first locking hole 314, so as to prevent the pivoting rack 32 and the nose portion 20 from pivoting relative to the positioning rack 31 and the saddle body 10, thus combining the nose-shaped saddle stably.
When not in use, the rider only has to press the engaging portion 344 of the engaging member 342 via the first locking hole 314 to make the moving section 343 of the engaging member 342 compress the spring 341, when the engaging portion 344 is separated from the first locking hole 314 of the positioning rack 31 completely as shown in FIG. 13, the pivoting rack 32 will rotate relative to the positioning rack 31. At that time, the rider can pull the nose portion 20 to make the pivoting rack 32 pivot and release the engaging member 342 as shown in FIG. 14. During the pivoting process of the pivoting rack 32, the assembling opening 326 of the pivoting rack 32 will be separated from the first locking hole 314 and face to the first positioning surface 311, and the first positioning surface 311 will block the control assembly 34 and compress the spring 341 via the engaging member 342, such that the engaging member 342 will be retracted in the assembling groove 325 completely.
When the nose portion 20 and the pivoting rack 32 downward pivoting to the position where the assembling opening 326 of the pivoting rack 32 opposite the second locking hole 315 of the positioning rack 31, the control assembly 34 will be released by the first positioning surface 311, and the spring 341 will be restored to push the moving section 343 of the engaging member 342, so as to make the engaging portion 344 of the engaging member 342 locked in the second locking hole 315, thus restricting the pivoting rack 32 as shown in FIG. 15. At that time, the pivoting rack 32 will move the nose portion 20 to make the top surface 21 of the nose portion 20 vertical to the top surface 111 of the saddle portion 11, thus forming the saddle without nose portion as shown in FIGS. 16 and 17. The structure of the pivoting unit 30 for pivoting the nose portion 20 to the saddle body 10 is not limited to that of the present invention, the pivoting unit 30 can also be an ordinary hinge or link mechanism.
To summarize, the bicycle saddle structure of the present invention has high riding comfort and can be changed to the nose-shaped saddle or the saddle without nose portion according to the requirement of the rider. The saddle body 10 can be separated from the nose portion 20 only by pressing the engaging member 342, and the control assembly 34 can be locked automatically after changing the position of the nose portion 20. Thereby, such a structure has high applicability and is convenient to use.
