## Background
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention is a CIP of application Ser. No. 14/472,374, filed Aug. 29, 2014, the entire contents of which are hereby incorporated by reference.


Description of the Prior Art
A conventional punching training device has a structure including a base, a punching cylinder extending upward from the base, and elastic element between the base and the punching cylinder, such as a spring. When the punching cylinder is hit to sway, the punching cylinder tends to sway back for the next hit. However, elastic elements such as springs are easily damaged, and the elastic force may result users being hurt.
Thus, a safer device as shown in U.S. Pat. No. 7,390,288 introduced a roly-poly structure. The device includes a base and a punching cylinder fixed onto the base wherein the bottom of the base is sphere-shaped and the base has a larger weight than the punching cylinder. When the punching cylinder is hit to sway, the base also sways. Due to the heavier base, the punching cylinder tends to sway back to a vertical position to be ready for the next hit.
However, the base is solid and made of cement. As a result, the base may result users hurting when users accidentally hit the base. In addition, the base may result abrasion of ground.
SUMMARY OF THE INVENTION
The main object of the present invention is to provide a punching training device which tends to retain vertically and having several punching targets.
To achieve the above and other objects, a punching training device of the present invention includes a base, a barrel, and a punching member.
The base includes an upper shell and a lower shell wherein the lower shell is made of resilient material. The base is formed with a cavity inside. The base further defines a vertical central axis. The cavity is located at the central axis. At least part of outer surface of the lower shell is a convex cambered face. The upper shell has a connecting portion at a top thereof.
The barrel has a shape corresponding to the cavity to be received in the cavity. The barrel has a barrel opening to allow water or sand to be filled into.
The punching member is disposed on the connecting portion of the upper shell and further extends upward. The punching member has at least one punching portion at an end of the punching member distant from the base.
Thus, the barrel is able to keep the base vertically even if the punching member is punched to sway. Besides, the base made of high resistance foam material can be another target to hit.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to FIG. 1 to FIG. 5, the punching training device of the present invention includes a base 10, a barrel 20, a punching member 30, and a covering coat 40.
The base 10 is made of resilient material, such as high resistance foam material (HR). The base 10 includes an upper shell 11 and a lower shell 12. The upper shell 11 is formed with a first recess 111, and the lower shell 12 is formed with a second recess 121. When the upper shell 11 is connected with the lower shell 12, the first recess 111 and the second recess 121 form a cavity. The base 10 defines a vertical central axis. The cavity is located at the central axis. At least part of outer surface of the lower shell 12 being a convex cambered face. Preferably, a bottom face of the lower shell 12 is a flat plane, and the convex cambered face connects the bottom face and a lateral face of the lower shell 12. The upper shell 11 has a connecting portion 112 at a top thereof. More specifically, outer surfaces of the upper shell 11 and of the lower shell 12 are continuously connected to make the base 10 substantially sphere-shaped. Preferably, the upper shell 11 and the lower shell 12 are fixed together by a tape surrounding the base 10.
In the present embodiment, the lower shell 12 is embedded with a metal skeleton 122 which includes a bottom plate 1221, a plurality of stands 1222, and a top frame 1223. The bottom plate 1221 is located at the bottom of the lower shell 12, and the top frame 1223 is located at the top of the lower shell 12. The stands 1222 are arranged in interval and connect the bottom plate 1221 and the top frame 1223. The skeleton 122 helps lower the center of weight of the base 10. Besides, when the present invention is hit by a user, the stands 1222 help bring the base 10 back to vertical position.
The barrel 20 has a shape corresponding to the cavity to be received in the cavity. More specifically, the barrel 20 is plastic barrel which is made by blow-molding. The barrel 20 encloses a receiving room for receiving water or sand. The barrel 20 has a barrel opening 21 for the water or the sand to be filled into. The barrel opening 21 is exposed outside the upper shell 11. The barrel 20 has a lower portion larger than an upper portion thereof.
The punching member 30 is disposed on the connecting portion 112 and further extends upward. The punching member 30 has at least one punching portion at an end thereof distant from the base 10. In the present invention, the punching member 30 is column-shaped and is made of resilient material. The punching member 30 is fixed to the connecting portion 112 by any possible means, such as close-fit or adhesives.
The covering coat 40 includes an upper coat 41 and a lower coat 42. The lower coat 42 covers the lower shell 12 and has an opening upward. The upper coat 41 covers the punching member 30 and the upper shell 11 and has an opening downward. The upper coat 41 has at least one first connecting element around the opening thereof. The lower coat 42 has at least one second connecting element around the opening thereof. The upper coat 41 and the lower coat 42 are connected when the first connecting element and the second connecting element are engaged. In the present embodiment, the first connecting element and the second connecting element are corresponding zipper elements to compose a zipper 43. The upper coat 41 has a skirt flange 411 downward extending from the lower edge thereof. The skirt flange 411 covers the first connecting element and the second connecting element (in other words, the zipper 43) when the first connecting element is engaged with the second connecting element.
Practically, the lower shell 12 can be placed into the lower coat 42 in advance, and the barrel 20 is filled with water, sand, or others to increase weight of the barrel 20. And then, the barrel 20 is placed into the second recess 121, and the upper shell 11 further covers the barrel 20. Thereafter, the punching member 30 is installed on the connecting portion 112 of the upper shell 11. Finally, the upper coat 41 covers the punching member 30 and the upper shell 11, and the first connecting element and the second connecting element are connected to position the upper coat 41 and the lower coat 42 together.
Because the base is made of high resistance foam material so as to be another target to hit for users. In addition, the lower shell has a cambered face, and the barrel is located at the central axis so that the base is able to act as a roly-poly. Besides, the shell can prevent the barrel from being abrasion by ground.
Besides, the skeleton can lower the center of weight of the lower shell, so strength of structure is enhanced.
