ABSTRACT:
TECHNICAL FIELD
The present invention pertains generally to the field of martial arts, and in particular to a martial arts training device which can be removably attached to a conventional punching bag.
BACKGROUND ART
Martial arts training devices for developing skill in martial arts are well known in the art. These devices provide simulated aims and legs for practicing various martial arts techniques. In one category of trig device, an attachment is connected to a conventional punching bag. For example, U.S. Pat. No. 5,697,872 illustrates a martial arts training device which attaches to a cylindrical heavy bag. The training devices includes an elongated tubular member (arm) having a first and second distal portions, wherein the tubular member has a first arcuate bend adapted to matingly engage the exterior of the heavy bag along a circumference thereof. An elongated elastomeric member having opposed ends fixed to the tubular member secures the tubular member about the bag. And, U.S. Pat. No. 5,800,319 defines a sparring device composing a columnar member, such as a punching bag, and a sparring member. The sparring member includes a belt portion which is fastened upon the columnar member. The sparring member also includes at least one arm portion which is normally disposed in a horizontal direction with its inner end joined to the bell portion and its outer end in at least one arcuate path the radius of which extends from the inner end of the arm portion. In both of the aforementioned devices, because of the manner in which the arms are attached, when the arms are struck with a martial arts blow, they freely move or gyrate with respect to the punching bag. This movement poorly simulates the resistance that would typically be offered by a martial arts opponent.
Another type of martial arts training device comprises a rigidly mounted tree-like “dummy” made of plastic or wood. The dummy has a plurality of rigidly attached protruding limbs which are used to practice blocking and hitting maneuvers. Since the limbs are rigidly attached to the dummy, and the dummy is rigidly attached to a support structure such as the floor or a wall, when the limbs are hit they do not move at all. Here too the simulation of an actual opponent is seriously lacking.
DISCLOSURE OF INVENTION
The present invention is directed to an improved martial arts training device which overcomes the disadvantages of prior art devices. In the present invention the arms are rigidly attached to the punching bag, so that when the arms are struck they do not move with respect to the punching bag, but rather cause the suspended punching bag to move. In this manner, the normal resistance offered by the limbs and body of a martial arts opponent is accurately simulated. Additionally, the present invention is much less expensive than the rigid dummy-type training devices currently available on the market.
In accordance with a preferred embodiment of the invention, a martial arts training device for removable attachment to a punching bag having an outer surface includes a covering which rigidly attaches to a portion of the outer surface of the punching bag. One or more connectors fixedly hold the covering in place on the punching bag. One or more outwardly projecting arms have an inward end having a flange. The martial arts training device is attached to the punching bag so that the flange is captively disposed between the covering and the punching bag.
In accordance with an important aspect of the invention, once attached, the arm is substantially immovable with respect to the punching bag.
In accordance with an important feature of the invention, the arm may either be oriented horizontally, or may be oriented downward to simulate a leg.
In accordance with another important aspect of the invention, three arms are utilized.
In accordance with another important feature of the invention, the arm tapers outwardly toward its tip.
In accordance with another preferred embodiment of the invention, the arm is rigidly connected to the covering.
In accordance with another important aspect of the invention, the arm is integrally molded with the covering to form a single unit.
Other features and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
