DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
(11) Referring to FIGS. 3-6, a rebounding pivot module in accordance with the present invention is shown. The rebounding pivot module generally comprises a bouncing device set 1 and a mounting shaft 2. The bouncing device set 1 is connected to the mounting shaft 2. The mounting shaft 2 comprises a shaft body 21, and a mounting plate 22 located at one end of the shaft body 21. In the present preferred embodiment, the mounting plate 22 and the shaft body 21 are integrally made in one piece. The mounting plate 22 provides a plurality of mounting through holes 221 for the insertion of respective fastening members (not shown).
(12) FIG. 2 is an exploded view of the bouncing device set 1. As illustrated, the bouncing device set 1 comprises a barrel 11, connecting tube 12, a connection rod 13, a socket 14, a first guide block 15, a bouncing barrel 16, an elastic member 17, a second guide block 18 and a lock device 19. The barrel 11 is a hollow member. The connecting tube 12 is fixedly accommodated in one end of the barrel 11, having a plug hole 121 located in each of the two opposite ends thereof. These plug holes 121 have a hexagonal cross section. One plug hole 121 accommodates the opposite end of the shaft body 21 of the mounting shaft 2. The opposite end of the shaft body 21 is configured to fit the hexagonal configuration of the plug holes 121 of the connecting tube 12. The opposite end of the barrel 11 is tooth shaped. The connection rod 13 has one end thereof plugged into the other of the plug hole 121 of the connecting tube 12. In the present preferred embodiment, the connection rod 13 is a hexagonal rod fitting the hexagonal configuration of the plug holes 121, having a flange 131 extended around the periphery of the one end thereof that is connected to the connecting tube 12. The socket 14 is attached onto the opposite end of the connection rod 13. In the present preferred embodiment, the outer perimeter of the socket 14 exhibits a polygonal shape, for example, octagonal shape. The socket 14 has one end thereof attached onto the connection rod 13 and abutted against the flange 131, and an opposite end thereof tooth shaped. The toothed shaped opposite end of the socket 14 defines a plurality of engagement grooves 141. The first guide block 15 is attached onto the connection rod 13, having one end thereof tooth shaped. After the first guide block 15 is attached onto the connection rod 13, the socket 14 is accommodated in the tooth shaped end of the first guide block 15 and, the tooth shaped end of the first guide block 15 is aimed at the tooth shaped opposite end of the barrel 11. The opposite end of the first guide block 15 is a beveled end.
(13) Referring to FIG. 2 again, the bouncing barrel 16 is a hollow member comprising an opening 161 at one end thereof and a through hole 162 at an opposite end thereof. The elastic member 17 and the second guide block 18 are inserted into the opening 161 of the bouncing barrel 16 in a proper order. The second guide block 18 is linked with the elastic member 17. In the present preferred embodiment, the elastic member 17 is a spring. The second guide block 18 defines a guide hole 181. Further, the second guide block 18 has one end thereof tooth shaped and facing toward the beveled opposite end of the first guide block 15. The tooth shaped end of the second guide block 18 defines a plurality of guide edges 182. During mating installation of the bouncing barrel 16 and the barrel 11, the opposite end of the connection rod 13 is inserted in a proper order through the second guide block 18, the elastic member 17, the through hole 162 of the bouncing barrel 16 and then the lock device 19. The lock device 19 comprises a gasket 191 and a lock nut 192. The gasket 191 and the lock nut 192 are mounted onto the connection rod 13 to lock the opposite end of the connection rod 13 to the bouncing barrel 16. FIG. 3 illustrates the bouncing device set 1 assembled.
(14) Referring to FIGS. 4-10, there are a series of schematic operational side view of the present invention. FIG. 3 shows the first state of the bouncing device set 1, that is, at rest, as shown in FIG. 4, where the peaks of the tooth shaped end of the first guide block 15 are stopped against the respective peaks of the tooth shaped end of the barrel 11 and, the guide edges 182 of the second guide block 18 are stopped at the low side of the beveled end of the first guide block 15. As illustrated in FIG. 5, when the barrel 11 of the bouncing device set 1 is biased by an external force, the peaks of the tooth shaped end of the first guide block 15 are moved away from the respective peaks of the toothed end of the barrel 11, the guide edges 182 of the second guide block 18 are moved from the low side of the beveled end of the first guide block 15 toward the high side thereof to compress the elastic member 17, as illustrated in FIG. 6, and thus, the first guide block 15 is moved along the tooth shaped end of the barrel 11 till that the bouncing device set 1 is rotated to a first angular position. After the guide edges 182 of the second guide block 18 passed over the high side of the beveled end of the first guide block 15, the bouncing device set 1 is rotated into a second angular position, as illustrated in FIG. 7, finally, the guide edges 182 of the second guide block 18 are moved into the respective engagement grooves 141 of the socket 14 to lock the bouncing device set 1 in position, as shown in FIG. 8. On the contrary, if the bouncing device set 1 is rotated by an external force through an angle smaller than the second angle, the guide edges 182 of the second guide block 18 are moved away from the engagement grooves 141 of the socket 14 to drive in the reversed direction, as illustrated in FIG. 9, causing the second guide block 18 to push the first guide block 15 back to the low side of the tooth shaped end of the barrel 11, at this time, the elastic member 17 of the bouncing device set 1 imparts an elastic restoring energy in the reversed direction, causing rotation of the bouncing device set 1 through an angle smaller than the first angle, at final, the bouncing device set 1 returns to the initial position and, the first guide block 15 and the second guide block 18 are returned to the initial position and locked thereto.
(15) Although a particular embodiment of the invention 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.
