DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, a preferred embodiment in accordance with the present invention.
With reference to FIGS. 1-7, an angle adjustable bicycle saddle according to a preferred embodiment of the present invention comprises:
a seat post 10 including an inwardly curved groove 11 defined on a top of the seat post 10 and having multiple protrusions 111 successively formed on an inner wall of the inwardly curved groove 11 and in a tip tooth shape, and two troughs 12 defined on a free end of an outer wall of the inwardly curved groove 11;
a cushion 20 including a body 21 and a cap 22, wherein the body 21 has a curved holder 211 extending downward from a bottom of a center thereof and having an opening defined on a top of the curved holder 211, an arcuate abutting projection 212 extending from a bottom of the curved holder 211 with respect to the inwardly curved groove 11 of the seat post 10, multiple engagement portions 213 continuously arranged on an outer wall of the arcuate abutting projection 212, and two through holes 214 formed on the arcuate abutting projection 212 and corresponding to the two troughs 12 of the seat post 10, wherein the cap 22 is covered on the curved holder 211 of the body 21 so that the curved holder 211 has a hollow portion; and
a locking unit 30 including two fixing elements 31 and two stepped nuts 32, wherein the two fixing elements 31 are inserted through the two troughs 12 of the seat post 10 and the two through holes 214 of the body 21 of the cushion 20, a first end of a respective fixing element 31 is adjustably received in a respective trough 12 of the seat post 10, and a second end of the respective fixing element 31 is accommodated in the hollow portion of the curved holder 211 of the body 21, wherein a respective stepped nut 32 is locked with the second end of the respective fixing element 31 away from the respective trough 12.
Referring to FIGS. 2-6, when adjusting the body 21, the two fixing elements 31 are manually rotated loosely by using a wrench so that the multiple protrusions 111 of the seat post 10 disengage from the multiple engagement portions 213 of the cushion 20, the two fixing elements 31 slide in the two troughs 12 of the seat post 10, and the body 21 is adjustably moved upward or downward to a desired angle by a user. As shown in FIG. 3, the body 21 is located at a horizontal angle when riding a bicycle. As illustrated in FIG. 5, the body 21 is moved downward and faces forward at a low horizontal angle. With reference to FIG. 6, the body 21 is moved upward and backward at a high horizontal angle. After adjusting the body 21 to the desired angle, the two fixing elements 31 are rotated tightly by using the wrench so that the multiple protrusions 111 of the seat post 10 engage with the multiple engagement portions 213 of the cushion 20, thus fixing the cushion 20 at the desired angle easily. Accordingly, the angle adjustable bicycle saddle is not broken, bent or removed when riding on a bumpy road by engaging the multiple protrusions 111 of the seat post 10 with the multiple engagement portions 213 of the cushion 20 and locking the seat post 10 with the cushion 20 by using the two stepped nuts 32 and the two fixing elements 31, thus obtaining security, angular adjustment, and safety.
With reference to FIG. 7, the respective fixing element 31 of the locking unit 30 is inserted through a respective through hole 214 of the body 21 of the cushion 20 and the respective trough 12 of the seat post 10, wherein the second end of the respective fixing element 31 is accommodated in the hollow portion of the curved holder 211 of the body 21, and the first end of the respective fixing element 31 is received in the respective trough 12 of the seat post 10, wherein the respective stepped nut 32 is locked with the first end of the respective fixing element 31 away from the respective through hole 214 of the body 21 of the cushion 20. When adjusting the body 21, the cap 22 is removed from the curved holder 211 of the body 21, the respective fixing element 31 is rotated loosely by way of the wrench so that the multiple protrusions 111 of the seat post 10 remove with the multiple engagement portions 213 of the cushion 20, the respective stepped nut 32 slides in the respective trough 12 of the seat post 10, and the body 21 is adjustably moved upward or downward to the desired angle by the user. After adjusting the body 21 to the desired angle, the respective fixing element 31 is rotated tightly by using the wrench so that the multiple protrusions 111 of the seat post 10 engage with the multiple engagement portions 213 of the cushion 20, thus fixing the cushion at the desired angle easily. The cap 22 is covered on the curved holder 211 of the body 21 so that the multiple protrusions 111 of the seat post 10 engage with the multiple engagement portions 213 of the cushion 20, and the seat post 10 is locked with the cushion 20 by screwing the respective stepped nut 32 with the respective fixing element 31, thus enhancing the security and avoiding fracture, bending, and removal, when riding on the bumpy road. Preferably, the angle adjustable bicycle saddle does not move or change its angle, thus enhancing the safety.
In another embodiment, as shown in FIG. 8, the multiple protrusions 111 of the inwardly curved groove 11 of the seat post 10 are a smooth plane, the multiple engagement portions 213 of the curved holder 211 of the body 21 are a smooth plane, and the seat post 10 is locked with the cushion 20 by screwing he respective stepped nut 32 with the respective fixing nut 31, thus obtaining the security. Referring to FIG. 9, in another embodiment, the multiple protrusions 111 of the inwardly curved groove 11 of the seat post 10 are a projected tooth, the multiple engagement portions 213 of the curved holder 211 of the body 21 are a projected tooth, such that the multiple protrusions 111 of the seat post 10 engage with the multiple engagement portions 213 of the cushion 20, and the seat post 10 is locked with the cushion 20 by screwing the respective stepped nut 32 with the respective fixing nut 31, thus enhancing the security.
In another embodiment, as shown in FIGS. 10 and 11, the seat post 10 includes the inwardly curved groove 11 formed on the top thereof, the inwardly curved groove 11 has three notches 12 defined on the free end thereof, and the arcuate abutting projection 212 has three through holes 214 formed thereon and corresponding to the three troughs 12 of the seat post 10.
While various embodiments in accordance with the present invention have been shown and described, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
