Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] 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. [0003] 2. Brief Description of the Related Art [0004] 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. [0005] 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 carr...

AI Technical Summary

Benefits of technology

[0006] An 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.

[0007] 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.

[0008] 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.

Problems solved by technology

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.
