Adjustable punching bag
An adjustable punching bag includes an outer jacket bag and an inner bag set received in the outer bag. The inner bag set contains core stuffing, in which the content and kind of the stuffing can be adjusted to change the weight of the entire punching bag for meeting different practicing needs of users. Further, it is convenient to pack, store all parts thereof to lower delivery cost.
1. Field of the Invention
The present invention is related to an adjustable punching bag and particularly to a punching bag, which provides adjustable weight and hardness and is able to be folded for packing, storing and delivering conveniently.
2. Brief Description of the Related Art
The punching bag is frequently used during practicing skill of art of attack and defense. In order to meet different personal needs, punching bags in different weights are available for being chosen as desired. However, it is known that a lot of punching bags have to be prepared and the volumes of the punching bags are huge such that problems with regard to storage, packing and delivery in addition to handling cost are worth us to care.
As the foregoing, the conventional punching bag occupies limited space, requires high delivery cost. And, it is unable for the user to adjust weight thereof suitable for personal practice habit and load carrying ability. How to solve the preceding problems is a subject has to be overcome.
SUMMARY OF THE INVENTIONAn object of the present invention is to provide an adjustable punching bag to improve deficiencies of being not possible for weight adjusting, packing and storing.
Another object of the present invention is to provide an adjustable punching bag, with which it is not necessary for manufactures to fabricate punching bags in different weights and to worry about unsold punching bags in stocks.
In order to achieve the preceding objects, the adjustable punching bag of the present invention includes an inner bag set and an outer jacket bag. The outer jacket bag provides an inlet for receiving the inner bag set. The inner bag set includes a first inner bag, a second inner bag and multiple daughter bags. The second inner bag and the daughter bags are filled with stuffing and placed in the outer jacket bag sequentially. The stuffing provides with gradients in different densities for controlling weight of the entire punching bag. The stuffing can be liquid, solid or gas. Liquid can be water, liquids in different specific weights or curdled glue formed of water with agent. Solid can be plastic air bag or lead blocks, which affect weight. Gas is capable of occupying space for decreasing weight. Even more, the stuffing can be any mixture of liquid, gas and solid. Thus, the weight of the punching bag is under control and the required weight can be obtained and precise training of skill with regard to art of attack and defense can be achieved. The cap knob at the top of the second inner bag can be removed to take out the daughter bags or the cap knob at the bottom of the second inner bag can be removed to release the stuffing completely. Further, the outer jacket bag and the inner bag set can be folded and stored in a box simply for being carried with the user conveniently.
BRIEF DESCRIPTION OF THE DRAWINGSThe detail structure, the applied principle, the function and the effectiveness of the present invention can be more fully understood with reference to the following description and accompanying drawings, in which:
Referring to FIGS. 1 to 3, an adjustable punching bag apparatus of the present invention includes an inner bag set and an outer jacket bag 30. The outer jacket bag 30 provides several pieces of metal chains 31 and a tying cord 32 at the upper end thereof. The inner bag set includes a first inner bag 10, a second inner bag 20 and a plurality of daughter bags 23.
Wherein, the outer jacket bag 30 receives the inner bag set and the metal chains 31 is used for hanging the outer jacket bag 30. The tying cords 31 are used for closing the opening of the outer jacket bag 30.

It is appreciated that the adjustable punching bag of the present invention is to change the weight of the whole punching bag by means of changing quantity and kind of the stuffing in the inner bags and there is no restriction to limit the quantity and the kind of the used stuffing and it can be mixed based on the need of the user. Further, the cap knob 21 at the bottom of the second inner bag 20 is opened first to discharge the water L in the inner bag 20 after the punching bag has been done completely. Then, the cap knob 22 is opened and the daughter bags 23 are taken out with the gas in the daughter bags 23 being released. Thus, all the bags are folded and placed in a box B for storage and being carried with the user. In case of the soft bags being used, the box B can be reduced in size for being stored, packed and delivered more conveniently.
While the invention has been described with referencing to a preferred embodiment thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
