Field of Invention
The present invention relates to an air-water punching bag structure, in particularly, a bag structure which weight and firmness can be adjusted and which has multi-training functions.
Description of Related Arts
Conventional punching bag for combat training is a closed bladder using solid (such as sand), liquid (such as water), or gas (such as air) as filler and is placed inside of an external bag.
It is easy and cheap to obtain the fillers, but the ideal weight of a punching bag, which may impact the training effect, is about half of its user's weight. Also, when solid is used as filler in inner bladder, the weight of the punching bag becomes too heavy to be easily moved or stored. When liquid is solely used as the filler of the inner bladder, the heavy weight of punching bag will result in poor training effect. When gas is used as filler of the inner bladder, the punching bag is usually too light and requires other material to fix it in place. Thus, all of the above can result in poor training effect.
In addition, for conventional punching bag structure which adopts solid, liquid, or gas as filler, there is only one tactile feel. When filling with solids, punching bag gives a firm texture while liquids add a little softness and resilience. When filling with gas, punching bag is even more resilient. However, none of the foregoing fillers can be adjusted in the same structure to create different texture to satisfy different training techniques and users.
In addition, the conventional punching bag structure cannot integrate different training functions simultaneously (such as croissant move training, push-up training, sit-up training, Judo training, boxing training, upper cut training, tackle training, suppression training, and weight training). More training equipments need to be purchased in order to provide different training functions when using punching bag for different technique training, which further increases the training cost. Thus, the drawbacks of conventional punching bag need to be improved.
To overcome the existing problems of prior art, the present invention provides an air-water punching bag structure that uses liquids or colloid as the major weight source for the inner bladder structure and fills up the extra space with air. The external bag structure can integrate suspenders or handles to lower training cost and the weight and softness-hardness can be adjusted to meet the user's demand with different training functions for obtaining the training effect.
The present invention discloses an air-water punching bag structure that comprises an inner bladder, an external bag, at least one set of handles, at least two sets of first suspenders, and at least one set of second suspenders.
The inner bladder is a hollow bladder that further comprises one gas container and one liquid container. The gas container is a bladder for containing gas and is housed in the inner layer of the inner bladder. The gas container even comprises at least one air valve. The air valve is located on one side of the gas container and can be connected to the interior of the gas container to adjust the pressure and volume of the gas container and adjust the location of the liquid and colloid inside the liquid container. Therefore, the weight of the inner bladder can be adjusted to satisfy user's demand and accomplish better combat training effect. The liquid container is a bladder for containing liquid or colloid and is housed in the outer layer of the gas container. The liquid container even comprises at least one water inlet set and one air valve. The water inlet set is located on top of the liquid container and can be connected to the interior of the liquid container to adjust the weight of the liquid or colloid of the liquid container. The air valve of the liquid container is located on top of the liquid container or on top of the water inlet set and can be connected to the inside of the liquid container to adjust the hardness of the inner bladder through inflating or exhausting with the air valve of the liquid container, and thus to obtain the function of adjusting punching texture.
The external bag covers the outer layer of the inner bladder and further comprises a body, protection cover, plural hidden suspenders, and at least two connection straps. The body is a hollow bag that has a first connecting part. The connecting part is located at the edge of the opening of the body. An end of the protection cover can be connected to the body and the side protection edge can be folded inside out to cover the opening and the first connecting part of the body and even comprises plural lacing holes and one second connecting part. The lacing holes are located on the circular surface of the protection cover. The second connecting part is located at the edge of bottom of the protection cover and can be connected to the first connecting part of the body. One end of the hidden suspenders is fixed at the inner layer of the opening of the body and the other end can go through the corresponding lacing holes of the protection cover or can be fixed at the bottom of the protection cover. Each of the connection strap is respectively located on each side of the body with a connecting part. The connecting part is located at the connecting area, but not fixed on the body, while the other areas of the connecting strap are fixed on the body.
The handle set is removable and has multiple handles at different locations and a connecting part. The connecting part is located on one end of the handle set and can be fixed on the connecting part of the connecting strap. The first suspender set is removable and one end of each the first suspender set can go through the connecting part of each the connecting strap and between the external bag of the body. The second suspender set is removable and one end can be fixed on the out layer of the body of the external bag.
Preferably, the air valve of the gas container and the air valve of the liquid container are those for inflating balls or air beds.
Preferably, the external bag comprises one waterproof layer housed between the body of the external bag and the inner bladder. The opening of the waterproof layer can open and close.
Preferably, the second suspender set can adjust its length.
The presently preferred embodiment and related aspects of the invention will now be described with reference to the accompanied drawings.

The inner bladder 10 is a hollow bladder that further comprises one gas container 11 and one liquid container 12, as shown in
As shown in
The handle set 30 is removable and has multiple handles at different locations and one connecting part 31. The connecting part 31 is located on one end of the handle set 30 and can be fixed on the connecting part 251 of the connecting strap 25. The first suspender set 40 is removable and one end of each the first suspender set 40 can go through the connecting part 251 of each the connecting strap 25 and between the external bag 20 body 21. The second suspender set 50 is removable and the length thereof is adjustable and one end thereof can be fixed on the out layer of the external bag 20 body 21.
First, the inner bladder 10 was put into the external bag 20 and the inner bladder 10 of the gas container 11 was injected with air via the air valve 111 on the gas container 11. The volume of the gas container 11 will increase due to the pressure increase inside the gas container 11 and then the volume of the inner bladder 10 of the liquid container 12 will be reduced.
Then the water inlet set 121 on the liquid container 12 is opened to allow the user to add certain amount of liquid or colloid into the inner bladder 10 of the liquid container 12 via the water inlet set 121 on the liquid container 12. Meanwhile, the top of liquid or colloid inside the inner bladder 10 of the liquid container 12 is filled with air.
Finally the water inlet set 121 on the liquid container 12 is closed and the air valve 122 on the liquid container 12 is opened for injecting air into the inner bladder 10 of the gas container 11 via the air valve 111 of the gas container 11. The volume increases due to the pressure increases inside the inner bladder 10 of the gas container 11 and thus decreases the volume of the inner bladder 10 of the liquid container 12. Meanwhile, the level of liquid or colloid inside the inner bladder 10 of the liquid container 12 will rise due to compression and the air inside the inner bladder 10 of the liquid container 12 will be exhausted via the air valve 122 until the liquid or colloid inside the inner bladder 10 of the liquid container 12 is drained via air valve 122, meaning the air inside the inner bladder 10 of the liquid container 12 is completely exhausted. Meanwhile, the air injection into gas container 11 via the air valve 111 of the gas container 12 is stopped and the air valve 122 of the liquid container 12 is closed to completely seal the inner bladder 10 of the liquid container 12.
The inner bladder 10 of the liquid container 12 is completely filled with demanded amount of liquid or colloid in accordance with user's training need to obtain desired texture of punching at practice and change the texture of punching via changing the pressure of the gas container 11, and thus result in better training effect. The liquid or colloid and air inside the inner bladder 10 all can be respectively exhausted via the water inlet set 121 on the liquid container 12 and the air valve 111 on the gas container 11, thus the air-water punching bag structure is easier to be stored and moved.
If the firmness of the air-water punching bag structure is desired to be increased, air can be injected into the inner bladder 10 of the liquid container 12 via the air valve 122 on the liquid container 12.
In addition, if the liquid of colloid inside the liquid container 12 is not filled all the way up, the liquid or colloid inside the liquid container 12 will jiggle when the air-water punching bag structure is punched with external force; therefore, the center of the air-water punching bag structure will be shifting. A user will have to additionally use his/her muscles in different parts of the body to obtain balance, and thus further train more small groups of muscles.
