BACKGROUND OF THE INVENTION
Cross Reference.
[0001] This application is based on and claims priority to United States Patent Application Serial Number 13/758,269 filed February 4, 2013 and United States Patent Application Serial Number 13/916,160 filed June 12, 2013.
Field of the Invention.
[0002] This invention relates generally to a training bag, and more particularly, but not by way of limitation, to a free standing training bag with a tripod base for use as a combat simulator.
Description of the Related Art.
[0003] The hanging heavy punching bag is one of the earliest forms of punching bag training devices. Hanging heavy bags suffer from several disadvantages, including the limitations presented by the requirement that such a bag must be hung from a ceiling. The installation is permanent, which requires a space within a gym, garage, or home dedicated exclusively for heavy bag training. Furthermore, the hanging heavy bag is designed for boxing and presents functional limitations to martial arts disciplines that employ inside, outside, and front leg kicks.
[0004] Free standing training bags were developed as an effective alternative to hanging heavy bags that require physically mounting the hanging bags to structural elements within the ceiling framing members. Free standing punching bags are typically mounted to a heavy base which rests on the ground surface and therefore do not require ceiling installation. Free standing punching bags are typically built upon a large weighted base filled with water, which may weigh in excess of 275 lbs (125 kg) in order to keep the bag upright during use. Disadvantages of the current free standing bag structures include: the requirement to fill with water, or in some cases sand; the need for a large volume base, which limits the striking surface; and the problem of physically moving the free standing bag.
[0005] Functional disadvantages of current free standing bags include a minimum lower striking surface due to the large area required by the base and limitations regarding height. The limited striking surface of free standing bags is particularly limiting to many styles of martial arts or combat sports that employ lower level kicks or strikes. Many free standing bags are height adjustable, which is an impractical feature for a dynamically changing martial arts class.
[0006] The large base for existing free standing bags may reach heights of 20 inches (50.8 cm) from the ground which eliminates this area for striking purposes. Additionally, the large base presents a formidable hurdle for children or other vertically challenged athletes.
[0007] Additionally, no invention has effectively produced a fight simulator which reflects an opponent's legs as targets as in a standing sparring position.
[0008] Based on the foregoing, it is desirable to provide a free standing bag that eliminates the need for a heavily weighted base, eliminates the need for filling with water, is easy to move, and provides a striking geometry that closely reflects the upper body and leg targets such that it satisfies the training needs for all martial arts or combat sport disciplines.
SUMMARY OF THE INVENTION
[0009] In general, in a first aspect, the invention relates to a free standing training bag comprising a base with a plurality of legs and an upper body mounted atop the base, where the upper body has at least one striking surface suitable for use in martial arts training. The base may have three legs. The base and upper body may be at least partially padded. The legs may be capable of being folded for storage.
[0010] Each of the legs may or may not comprise an internal structure element surrounded by padding. The internal structure elements may be made of plastic, metal, or other rigid but flexible material. The padding may be polyethylene or EVA foam or other strike-absorbing material. Each of the legs may be wrapped in vinyl or other fabric. Each of the legs may terminate in a foot, and the foot may be weighted.
[0011] The base may have a top, and each of the internal structure elements may protrude from the top of the base. Each of the internal structure elements may have a bend located above the top of the base such that the three internal structure elements are capable of being placed adjacent each other above the bend to form a center post with the three legs extending downward therefrom at an angle to form a stable tripod. The free standing training bag may further comprise a locating bracket extending from the top of the base such that the internal structure elements may lie against the locating bracket. The free standing training bag may further comprise a cap or other structural piece to unify the three leg tops atop the center post.
[0012] The upper body may have an internal void capable of receiving the center post. The upper body may be cylindrical, and the base may have a top that is cylindrical, where the top of the base and the upper body each have a circumference and the circumferences are generally equal. The upper body may be joined to the base via an attachment device, which may be a zipper. The upper body may further comprise at least one laterally projecting striking surface. The upper body may or may not further comprise at least one internal support. The upper body may comprise polyethylene foam wrapped in vinyl or other fabric.

DETAILED DESCRIPTION OF THE INVENTION
[0015] The devices and methods discussed herein are merely illustrative of specific manners in which to make and use this invention and are not to be interpreted as limiting in scope.
[0016] While the devices and methods have been described with a certain degree of particularity, it is to be noted that many modifications may be made in the details of the construction and the arrangement of the devices and components without departing from the spirit and scope of this disclosure. It is understood that the devices and methods are not limited to the embodiments set forth herein for purposes of exemplification.
[0017] In general, in a first aspect, the invention relates to a free standing punching and kicking bag built upon a tripod base. The free standing training bag may be used as a combat simulator. As seen in Figure 1, the free standing training bag may be comprised of two primary parts: a lower body comprised of a padded tripod base 1 and an upper body 2 comprised of a padded cylindrical striking target.
[0018] The tripod base 1 may have three legs 3. Each leg 3 may have an internal structure element 4. The internal structure elements 4 may be made of polypropylene, polyethylene, PVC, other plastic, metal, or other rigid but flexible material. Each internal structure element 4 may be surrounded by padding 5, as seen in Figure 4, and the padding 5 may be polyethylene or EVA foam or other strike-absorbing material. Each of the legs 3 may be wrapped in an outer skin 6 of vinyl or other fabric. Each leg 3 may terminate in a foot 7, which may be weighted. If the legs 3 do not have internal structure elements 4, as shown in Figures 14 through 16, each leg 3 may be comprised of padding, and the padding may be polyethylene or EVA foam or other strike-absorbing material. Each of the legs 3 may be wrapped in an outer skin 6 of vinyl or other fabric, and the padding in each leg 3 may be vacuum compressed and then released inside the skin 6, allowing the foam to expand to fill the skin. Again, each leg 3 may terminate in a foot 7, which may be weighted. The weight in each foot 7 may be sand.
[0019] The base 1 may be assembled such that the three legs 3 may swing together in a closed position for shipping and/or storage, as seen in Figures 2 and 14. The legs 3 may then be opened to form a stable base when in use, as seen in Figures 3 and 15. If the legs 3 have internal structure elements 3, the internal structure elements 4 may protrude from the center of each leg 3 at the top of the base 1, and each internal structure element 4 may have a bend 8 located between the top of the leg 3 and the end of the internal structure element 4 such that the three internal structure elements 4 form a center post 9 when the legs 3 are extended in an open position, as seen in Figure 3. The portion of the legs 3 adjacent the center post 9 may fit into or against a locating bracket 13 when fully extending, where the locating bracket 13 fits between the legs 3, as seen in Figures 2 through 4. The three legs 3 may be held in place in the open position by a structural piece 10 applied to the top of the center post 9, as seen in Figures 3, 4, and 5. The angle of the bend 8, and subsequently of the legs 3 when in the open position, may be any angle desired for optimal stability. This tripod structure may provide a low center of gravity from the broad footprint generated by the three legs 3. Additionally, each leg 3 may be further weighted with sand or another form of weight to further enhance stability.
[0020] The upper body 2 may be comprised of polyethylene foam or other strike absorbing material wrapped in vinyl or other fabric. The upper body 2 may be cylindrical or any other desired shape. During assembly, the foam may be vacuum compressed and then released inside the skin, allowing the foam to expand to fill the skin. If the legs 3 do not have internal structure elements, the upper body 2 may likewise not have a rigid internal structure. If the legs 3 do have internal structure elements 4, the upper body 2 may have a void at its center, which serves as a receptacle to receive the center post 9 of the base 1. The center post 9 may help hold the upper body 2 upright and in place during use, while the upper body 2 may in turn help hold the internal structure elements 4 in place as the center post 9. Either with or without internal supports, the bottom of the upper body 2 may generally have the same circumference as the top of the base 1, allowing the upper body 2 and the base 1 to form a single unit when the upper body 2 is in place on the base 1. The upper body 2 may be joined to the base 1 via an attachment device, such as a zipper 14 as shown in Figure 7, hook and loop material, both a zipper and hook and loop material, or any other suitable attachment device.
[0021] The free standing training bag may be constructed of various sizes. Larger sizes may accommodate multiple users in a group or class setting, while smaller sizes may be appropriate for individual users. The individual user version may include shoulders and arms 11, as shown in Figures 8 and 10, which convert the device into a highly effective grappling or wrestling throwing dummy. The shoulders and arms 11 may have any desired configuration, such as two shoulders and arms 11 configured similar to those of a person, as seen in Figure 8 and above in Figure 9, or each may branch out both upward and downward, as seen in Figure 11 and from above in Figure 10. The arms and shoulders 11 may be constructed with rigid but flexible internal posts 12, as shown in Figures 12 and 13, which enable life-like resistance and structure most closely resembling the body of an opponent. Alternately, the arms and shoulders 11 may not have a rigid internal structure.
[0022] There are several benefits to the free standing training bag/fight simulator. It may ship in two pre-assembled pieces, which may be shipped together or in two boxes. The lower body legs 1 may fold together, which provides additional freight advantages. The two pre-assembled pieces may be joined together easily by the user without the need for tools or hardware. The product may be pre-loaded with weighted feet 7 and therefore requires no filling with water or sand by the user. The complete assembly may weigh as little as 100 lbs. (45 kg), compared to upwards of 275 lbs. (125 kg) for current free standing bags, which makes them extremely difficult to move. Martial arts schools often move their free standing bags on and off the gym floor several times a day. The minimal weight of the current invention provides martial arts schools the ability to move the training product on and off the gym floor easily. The legs 1 may fold down and together, which provides the school owner or instructor the ability to store the fight simulator when not in use.
[0023] The free standing training bag may be considered a true combat simulator that provides both upper body and lower body striking targets. The lower body may allow athletes to perform inside and outside leg kicks in addition to groin kicks or strikes. The legs 1 may be padded down to within 5 inches (12.7 cm) of the floor, which provides a full striking surface, unlike any other product on the market. The scale of the fight simulator may be large enough to accommodate multiple users in a class setting, or may be scaled down for individual athlete training. The smaller individual athlete version may include the addition of shoulders and arms, which meets the needs of grappling, Judo, wrestling, and mixed martial arts. The addition of shoulders and arms may allow the free standing training bag to be used as a highly effective practice throwing dummy. The smaller individual grappling and mixed martial arts version may be made to accommodate various size and weights of athletes by varying the size and weight of the fight simulator. The smaller version may also accommodate putting on a Judo Gi jacket, which provides Judo disciplines a specialized and realistic practice throwing dummy.
a base with a plurality of legs; and
an upper body mounted atop the base, where the upper body has at least one striking surface suitable for use in martial arts training.
the base has a top;
each of the internal structure elements protrude from the top of the base;
each of the internal structure elements has a bend located above the top of the base such that the three internal structure elements are capable of being placed adjacent each other above the bend to form a center post with the three legs extending downward therefrom at an angle to form a stable tripod.
