DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in FIGS. 1 and 2, a boxing training device of the present includes a main body 10 and three boxing assemblies 20.
The main body 10 includes an upper portion and a lower portion, the upper portion has a substantially polygonal post 11, and the lower portion has a supporting base 12. More specifically, the post 11 is a tetragonal rod, the post 11 includes an upper surface and a plurality of side surfaces, and the supporting base 12 is a substantially cylindrical rod. The post 11 vertically fixedly disposed on the supporting base 12. Preferably, the area of a radial cross-section of the supporting base 12 is greater than that of the post 11, and the supporting base 12 is heavier than the post 11, such that the boxing training device can stand stably. In other embodiment, the post 11 may be detachably mounted to the supporting base 12, and thus it is to assemble, disassemble and store. Besides, the post 11 may be retractable and adapted for adjusting the positions of the respective boxing assemblies 20.
Each the boxing assembly 20 includes a shell body 21, a rod 22, a pivoting portion 23 and two resilient members 24.
In this embodiment, one of the boxing assemblies 20 is mounted to the upper surface of the post 11 and slightly slants upwardly, and the others of the boxing assemblies 20 are mounted to the corresponding left and right side surfaces of the post 11. The openings of the shell bodies 21 of the boxing assemblies 20 face substantially in the same direction (for example, face substantially frontward), such that the user can practice boxing with the boxing training device which can serve as a supposed competition, just like boxing in a real boxing competition, and the effect of practice is improved.
It is should be noted that in this embodiment, the boxing training device includes three boxing assemblies 20, and the boxing assemblies 20 are mounted to the upper, left and right side surfaces of the post 11 respectively. However, in other embodiment, the boxing training device may be mounted with one boxing assembly 20, and the boxing assembly 20 may be mounted to one of the upper surface and the side surfaces of the post 11. The boxing training device may be mounted with two or more than three of the boxing assemblies 20, and each of the boxing assemblies 20 may be mounted to any suitable position of the post 11 according to various requirements of user.
Each of the boxing assemblies 20 is fixedly or adjustably mounted to the post 11 via the shell body 21, and each of the shell bodies 21 defines a receiving space 211 and includes an opening.
Each rod 22 is pivoted to each shell body 21 respectively. More specifically, each rod 22 is disposed in the receiving space 211 through the opening of the shell body 21 and pivoted to each shell body 21 with each pivoting portion 23.
Either of two corresponding side surfaces of the rod 22 is formed with a round hole 221, and the shapes of the corresponding hole 221 and resilient member 24 may be, but not limited to, substantially complementary. The two holes 221 are formed substantially along the same axis which is substantially perpendicular to the axial direction of the pivoting portion 23. The holes 221 of the boxing assembly 20 mounted to the upper surface of the post 11 are formed substantially along a vertical (up-down) axis, and the holes 221 of the boxing assemblies 20 mounted to the left and right side surfaces of the post 11 are formed substantially along a lateral (left-right) axis, respectively.
Each pivoting portion 23 is adapted for connecting the shell body 21 and the rod 22 of each boxing assembly 20, the axial direction of each pivoting portion 23 is substantially perpendicular to the axis along which the holes 221 of the boxing assembly 20 are formed. In this embodiment, the pivoting portion 23 is formed as a pin penetrating through the shell body 21 and rod 22, such that the user can assemble the boxing assembly 20 quickly. However, in other embodiment, the shell body 21 and the rod 22 can be assembled in other manner. For example, two projections (equivalent to the pivoting portion 23) may protrude respectively from corresponding two inner sidewalls of the shell body 21 toward the receiving space 211, and two pivoting holes corresponding to the projections are formed on the rod 22 for the two respective projections fitting into; two projections (equivalent to the pivoting portion 23) may protrude outwardly from corresponding two side surfaces at one end of the rod 22 respectively, and two pivoting holes corresponding to the projections corresponding to the projections are formed at two sides of the shell body 21 for the two respective projections fitting into, such that the shell body 21 and the rod 22 are pivotally connected.
The boxing assemblies 20 mounted to the left and right sides of the post 11 are representatively described herein. As shown in FIGS. 3A and 3B, the two resilient members 24 of each boxing assembly 20 are located at two radial sides of the pivoting portion 23 respectively. More specifically, one end of each resilient member 24 is disposed in each hole 221, and the other end of each resilient member 24 is resiliently engaged against the inner sidewall of the shell body 21. When an external force is exerted on the rod 22, the rod 22 can swing between a first position and a second position around the pivoting portion 23.
Whereby, by utilizing the spring force of the two resilient members 24, the rod 22 tends to revert to be original state (as shown 3A) and swings between the first position and the second position around the pivoting portion 23 after an external force is exerted on the rod 22. Compared to a conventional structure, in the invention, the unexpected over swing of the rod 22 due to an unsuitable great external force is avoided, and it cannot cause damage to user and is safe.
Additionally, since the corresponding two side surfaces of one end of each rod 22 are formed with the round holes 221 for receiving one end of each of the resilient members 24 respectively, the resilient members 24 can be stably restrained, and the departure issue of the resilient members 24 can be prevented when the rod 22 swings.
It is noted that, as shown in FIGS. 3B and 4, the swinging direction of the rod 22 of the boxing assembly 20 mounted to the upper surface of the post 11 are different from that of the boxing assemblies 20 mounted to the left and right side surfaces of the post 11. More specifically, the rod 22 of the boxing assembly 20 mounted to the upper surface of the post 11 swings up and down substantially along the longitudinal direction of the main body 10. The boxing assemblies 20 mounted to the left and right side surfaces of the post 11 swing left and right substantially along the lateral direction of the main body 10. Hence, the user can practice boxing with the boxing training device which can serve as a supposed competition, just like boxing in a real boxing competition, and the effect of practice is improved.
Furthermore, as shown FIG. 1, the structural arrangement of the invention may be changed. For example, the boxing assemblies 20 may be detachably mounted to the post 11 via a sleeve 30. More specifically, the interior shape of the sleeve 30 preferably corresponds to the shape of one end of the post 11, such that the boxing assemblies 20 can be mounted to the upper, left and right side surfaces of the post 11 respectively, and the sleeve 30 is then fixedly mounted to the post 10. Since the sleeve 30 can be detachably mounted, the boxing assemblies 20 are easy to assemble and convenient to store, and the boxing training device is small in size.
In addition, each shell body 21 may be adjustably mounted to the post 11, and the boxing assemblies 20 can be therefore adjusted according to different user requiring position, such that the user can practice boxing with the boxing training device to simulate the offence and defense of a supposed competition, and the effect of practice is improved.
Moreover, in the invention, the shell body 21 and the rod 22 are pivotally connected to each other via the pivoting portion 23, so that the boxing training device is simple in structure and easy to assemble, the yield can be increased, and the production cost can be decreased.
Although particular embodiments of the invention have 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.
