Description

PRIORITY INFORMATION

This application claims the benefit of priority of U.S. Provisional Patent Application Ser. No. 61/445,768 filed on Feb. 23, 2011 and entitled “MARTIAL ARTS TRAINING DEVICE,” which is hereby incorporated by reference in its entirety.

FIELD

This description relates generally to a chest protector for martial arts training and competitive sparring.

BACKGROUND

Conventional martial arts chest protectors are generally made of padded material so that they can be worn to protect the user's body from physical contact. A conventional chest protector has front torso and side torso covering members, and shoulder straps. The shoulder straps can be tied together such that the chest protector covers the torso of the user. Traditional chest protectors generally have colored portions to differentiate two opponents from each other during competition sparring. The chest protector is sized and configured to allow the user the freedom to move, kick, and punch freely.
Conventional chest protectors are generally used during competitive sparring. During competitive sparring, traditionally, judges watch for competitors to get a clean hit to scoring areas of the chest protector. While this method has been used for many years, there has been controversy over scoring because of human error or the judges' subjectivity as to determining whether a clean hit to a scoring area of the chest protector has been made or not.
When training with traditional chest protectors, the only way a person knows if he/she hit the opponent wearing the traditional chest protector hard enough to register a point is to see visual feedback in terms of the opponent getting injured or for an instructor to comment on the power level of the person's kick or punch. Thus, the feedback regarding the punch and/or kick is provided by a person, either by the opponent's subjective opinion and/or by a third person, such as the instructor, who uses his/her expertise to make the subjective judgment.

The central rod 602 is disposed at or near the axial center of a cylindrical hollow tube conductor 604. The central rod and an inner surface 606 of the cylindrical hollow tube conductor 604 are electrically conductive.
FIG. 6B shows a cut-away front view of a portion of the shock sensor 60. The central rod 602 being at the axial center of the cylindrical hollow tube conductor 604, wherein the distance “d” is the same in a radial direction from the axial center to the inner surface 606 of the cylindrical hollow tube conductor 604.
Returning to FIG. 6A, the central rod 602 and cylindrical hollow tube conductor 604 are held in position by an insulating material 608. The central rod 602, the cylindrical hollow tube conductor 604, and the insulating material 608 are disposed in an outer protective tube 610. The outer protective tube may be made of a plastic material. The outer protective tube 610 should be elastic, such that it can be deformed due to pressure and return to its original shape. The central rod 602 is connected to a wire 612 at a junction 614. The cylindrical hollow tube conductor 604 is connected to another wire 616 via a connection junction 618. When sufficient pressure is provided to the protective tube 610, the protective tube 610 is elastically deformed and the cylindrical hollow tube conductor 604 is also deformed and/or moved so that the cylindrical hollow tube conductor's conductive inner surface 606 makes electrical contact with the central rod 602.
In an embodiment, the electrical contact between the conductive inner surface 606 and the central rod 602 completes a circuit and this completed circuit is detected by a control unit and the control unit stores into a memory this information as a numerical value. The control unit may sum the numerical value and store that value to memory. The control unit may display the value to a display unit. For example, the value may be a score made by an opponent during a martial arts match. The display unit may be a plurality of LED lights, such that the number of LED lights that are on is the number of contacts detected by the one or more of the shock sensor(s).
In an embodiment, the electrical contact between the conductive inner surface 606 and the central rod 602 completes a circuit and this completed circuit functions as a switch for completing the circuit for an output device.
For example, the completed circuit due to the contact between the central rod 602 and the cylindrical hollow tube conductor's inner surface 606 functions as a switch for completing the circuit for the sound emitter so that sound is emitted from the sound emitter.
For example, the completed circuit due to the contact between the central rod 602 and the cylindrical hollow tube conductor's inner surface 606 functions as a switch for completing the circuit for the light emitter so that light is emitted from the light emitter.
For example, the completed circuit due to the contact between the central rod 602 and the cylindrical hollow tube conductor's inner surface 606 functions as a switch for completing the circuit for the sound emitter and the light emitter so that sound is emitted from the sound emitter and light is emitted from the light emitter.
An example of the cylindrical hollow tube conductor 604 is a spring. In an example, the spring is a conductor. In another example, the spring includes a conductor in the inner surface 606 facing the central rod. The size of the spring determines the amount of pressure required to make the contact between the central rod 602 and the inner surface 606 of the cylindrical hollow tube conductor 604.
Another example of a shock sensor is an air pressure sensor. The air pressure sensor can comprise at least one air bag connected to an air inlet valve and an air outlet valve. The airbag can be configured on various parts of the front and left and right protective members of the chest protector so that the when the air bag is depressed, a stream of air is released from the air outlet valve to the switch. The switch would function to complete the circuit as described above for output devices, such as the sound emitter and/or the light emitter. The air inlet valve may be configured to be adjustable so that the pressure of the air bag may be adjusted according to the user's needs. The adjustment of the valve may be through a screw.
FIG. 7 shows an embodiment of the light emitter 70, which may be incorporated into any of the embodiments of the marital arts training device disclosed herein. The light emitter 70 includes a housing 700 that houses a circuit forming the control unit 702 for controlling LED lights 704, 706. The LED lights 704, 706 allow for the light emitter 70 to function as a score display component. When none of the LED lights 704, 706 are on, the score is zero. When one of the LED lights 704, 706 is on, the score is one. When both of the LED lights 704, 706 are on, the score is two.
In another embodiment, the score display component may be a LED display device. The score display component, for example, may be an electronic paper display device. The score display component, for example, may be a series of LEDs arranged and/or configured to display a number. The score display component is sufficiently protected to endure the use of the training device, for example, sufficiently protected to continue functioning even after receiving a punch and/or a kick thereto. The score display component is in communication with the control unit 702, which includes a processor and a memory. The processor calculates communicates to the memory and memory stores the score thereon. The display device displays the score.
FIG. 8 shows an embodiment of the sound emitter 80, which may be incorporated into any of the embodiments of the marital arts training device disclosed herein. The sound emitter 80 includes a front speaker 802 and a rear speaker 804. The front speaker is disposed near the hole at the front side of the chest protector.
