Description

KICK-BOXING EXERCISE DEVICE BACKGROUND OF THE INVENTION Technical Field Generally, the invention relates to an exercise device. Particularly, the invention relates to an exercise device which allows a user to simulate kick-boxing.

More particularly, the invention relates to an exercise device which includes a target section having the shape of a head, neck and torso of a human and a plurality of .•°target areas located on the target section which illuminate in a sequential pattern .to indicate the location which the user is to punch or kick to obtain a complete muscular and cardiovascular workout.

15 Background Information It has long been recognized by those in the fitness industry that boxing, and particularly kick-boxing, provides an intense muscular and cardiovascular workout.

The sport of kick-boxing requires strength, agility and endurance. A kick-boxer uses 20 his or her fists and feet to punch and kick an opponent in the head or body.

Throwing a punch requires the use of muscles ranging from the feet to the head and neck. Punches generate from the ground up with the kick-boxer using his or her back leg to push or thrust the upper body forward while the front leg supports this forward movement. In order to extend the punching arm, the kick-boxer rotates the upper body working the abdominal muscles while extending the punching arm to work the various muscles in the shoulders, arms and hands.

In order to kick an opponent, the kick-boxer must thrust one leg upwardly and outwardly to a height sufficient to contact the opponent in the head or torso, while supporting his or her body on one leg. Extending one's foot to a sufficient height to reach the head or torso of an opponent works the various leg and abdominal muscles and requires a great deal of flexibility and balance.

Further, while attempting to punch or kick the opponent, the kick-boxer must simultaneously avoid being kicked or punched by the opponent. The kick-boxer must be prepared to dodge the opponent's punches or kicks at any instant by balancing himself or herself on the balls of the feet. This allows the kick-boxer to quickly duck or back away from an oncoming punch or kick. This type of movement is typically known as "bobbing and weaving." The kick-boxer bobs and weaves to avoid being punched or kicked while looking an opportunity or "opening" to punch 10 or kick the opponent. Bobbing and weaving requires a great deal of foot movement, quickness and agility.

Thus, it can be seen that throwing punches and kicks while simultaneously avoiding the punches and kicks of the opponent works virtually every muscle in the kick-boxer's body and allows the kick-boxer to improve his or her flexibility, balance, quickness and agility. The problem with using kick-boxing as a type of exercise is that most individuals do not wish to engage in actual contact with an opponent and risk being hurt by a punch or kick to the head or torso. Those who partake in kickboxing as a sport are highly trained athletes who use state-of-the-art training equipment, safety equipment and expert instructors.

20 Heretofore, several devices have addressed this problem of providing a device which allows users to engage in kick-boxing as a muscular and cardiovascular workout without exposing the themselves to harm from a punch or kick of an opponent. For example, U.S. Patent No. 4,088,315 discloses a device for self defense training having an appearance of a human and including a plurality of targets which indicate where the user is to strike the dummy. The device includes several intricate mechanical joints which allow the limbs of the dummy to be placed in various attack positions. Additionally, the device includes a pressure sensitive floor pad which the user must stand on in order to activate the illuminated targets.

U.S. Patent No. 4,974,833 discloses an electronic martial arts training device having a two-dimensional outline of an opponent with various target modules which illuminate in a sequential pattern. The target section must be mounted on a wall or otherwise supported a sufficient height to simulate the height of an opponent. The device does not include a height adjustment mechanism and requires the user to mount the device on a wall or other support structure.

Although these devices are adequate for the purpose for which they are intended, these prior art devices requires either a substantial amount of horizontal floor space for the dummy and associated pressure sensitive floor pad or a substantial amount of wall space on which the target section must be mounted.

OOO:

06-Therefore, the need exists for a kick-boxing exercise device which allows a 15 user to simulate kick-boxing, which requires minimal horizontal floor space S- and minimal vertical wall space, and which is free of complicated mechanical joints and limbs which may break.

S•SUMMARY OF THE INVENTION Objectives of the present invention include providing a kick-boxing exercise device which allows a user to obtain a complete muscular and So cardiovascular workout by simulating the sport of kick-boxing without being subjected to punches or kicks.

o A further objective is to provide an exercise device which is freestanding and requires no mounting or support structures.

25 Another objective is to provide an exercise device which has the shape of a head, neck and torso of a human to give the user a realistic human-shaped target.

A still further objective is to provide an exercise device of simple construction, which achieves the stated objectives in a simple, effective and inexpensive manner, which solves some of the problems and satisfies needs existing in the art.

These objectives and advantages are obtained by the exercise device of the present invention, the general nature of which may be stated as including a base having a bottom portion and a top portion which extends upwardly from the bottom portion; a target section mounted on the base, said target portion having a shape of a head, neck and torso of a human and being free of outwardly extending limbs; a plurality of targets formed on the target section; each target including a light and a pad attached to the target section for cushioning an impact by a user.

In accordance with one of the features of the invention, target section 6 has a shape and configuration which emulates a head, neck and torso of a human.

Target section 6 includes a head 50, a neck 52 and a lower torso 54. Target section 6 is formed of a plastic material similar to that of base unit 4, such as a polypropylene, having a nominal wall thickness of 0.188 inches.

10 Target section 6 is formed with a recessed area 56 in the face, neck and *Q abdominal region thereof. Recessed area 56 receives a complementary-shaped foam pad 60 which, in a preferred embodiment, is formed of a self-skinning urethane foam. Foam pad 60 includes a face portion 62, an abdominal portion 64 "and a thin neck and chest portion 66 extending between and connecting face portion 62 and abdominal portion 64. Foam pad 60 is formed with a plurality of *.*holes 68 having a countersunk portion 70. A plurality of holes 72 are formed in target section 6 which align with holes 68 when foam pad 60 is placed within recessed area 56. A clip 74 extends through holes 68 of foam pad 60 and snap-fits with holes 72 of target section 6 to retain foam pad 60 within recessed area 56.

In accordance with another of the features of the invention, target section 6 includes eight indented target areas which are formed in target section 6 at strategic punching or kicking locations. Specifically, the target areas are located at a right eye area A, a left eye area B, a mouth area C, a chest or sternum area D, a right rib cage area E, a left rib cage area F, a right abdominal area G and a left abdominal area H. Each target area includes an LED which illuminates when the specific target area is to be struck by user 2. A wiring channel 76 is formed between the target areas for receiving the electrical wiring which supplies power to the LEDs. A plurality of openings 78 are formed in foam pad 60 which correspond to and align with target areas A-H and allow the LED to be seen therethrough when foam pad 60 is attached to target section 6.

In a preferred arrangement, a sensor switch adjustment dial 80 is positioned on the chest area of target section 6 and extends outwardly from recessed area 56 thereof Dial 80 allows the sensitivity of a motion sensor or tilt switch, described below, to be adjusted according to the punching strength of user 2. A cutout area 82 is formed in foam pad 60 which allows adjustment dial to extend through foam pad Electronic control unit 26 includes various buttons and displays which allow the user to adjust the skill level of kick-boxing exercise device 1, activate a digital timer, or select a specific target area which is to be illuminated or select one of several preprogrammed punching sequences.

Exercise device 1 is shown in FIG. 2 in an assembled position. Foam pad •is attached within recessed area 56 and is flush with the outer surface of 0 15 target section 6. Clips 74 extend through holes 68 and snap-fit with holes 72 to retain foam pad 60 within recessed area 56 of target section 6. Cap 42 is removed from the top end of stem 10 allowing sand, rock salt or some other suitable material to be poured within the hollow interior of base unit 4 for preventing kick-boxing machine exercise device 1 from moving during use.

Cap 42 is screwed or snap-fit over the opening of stem 10. An opening (not r •"shown) is formed in the bottom of target section 6 for receiving top stem 10 of S•base unit 4. An adjustment mechanism is positioned on the rear of target S• section 6 which slides within aperture 38 for releasably latching with one of the levels of notches In use, user 2 adjusts target section 6 to a height approximately the same •height as the user. User 2 positions his or her body a distance away from kick-boxing exercise device 1 whereby full extension of the user's arms or •legs will produce contact with but will not knock over kick-boxing exercise device 1. Electronic control unit 26 is turned on and one of several punching sequences may be activated or one specific target area may be selected by the user.

In the preferred embodiment, the punching sequences are grouped in two to three punch or kick combinations. One example of a punching sequence is 8 A-B, E-A, A-B, A-C, A-A, E-F, D-H-C, whereby each letter of the punch or kick sequence corresponds to the lettered target areas of FIGS. 2 and 3 In the preferred embodiment, the user will obtain a maximum muscular and cardiovascular workout by repeating each punching sequence for a total of three minutes alternating right and left hands or feet. The LEDs of each target area are illuminated when the user is to contact that particular location of target section 6. Foam pad 60 cushions the user's fists or feet to prevent injury when the user punches or kicks exercise device 1.

The speed in which the LEDs are illuminated in each sequence is determined by the skill level selected on electronic control unit 26. The advanced skill level includes a scoring system which allows user 2 to evaluate his or her performance. During this advanced skill level, the LEDs of each target area are sequentially illuminated, as with the beginner and intermediate skill levels, but preferably the control unit 26 will not illuminate a S. subsequent LED until the sensor or tilt switch detects that contact has been Smade with the currently lit LED. Additionally, a speaker may be provided ,within control unit 26 which beeps when an LED is illuminated. This advanced skill level allows the user to monitor the number of punches thrown within a specific amount of time allowing the user to track his or her quickness and reaction time.

Further, dial 80 may be preferably adjustable to vary the force of the punches or kicks required to "trip" the sensor or tilt switch and activate the next LED.

This allows the user to monitor his or her punching strength as the user is able to require that harder punches be thrown in order to trip the sensor or tilt switch.

Accordingly, exercise device 1 allows a user to simulate the sport of kickboxing without being subjected to harm from an opponents punches or kicks.

Base unit 4 supports target section 6 allowing exercise device 1 to be freestanding and easily movable for storing device 1 in a closet or corner.

Hollow base unit 4 allows exercise device 1 to be shipped at a relatively low cost, yet provides an access opening which allows the user to add weight to the base to prevent movement of the device during use. Target section 6 is vertically adjustable on base unit 4 allowing the user to position human-shaped target section 6 to various heights depending on the height of the user. Foam pad 60 cushions the punches and kicks of the user to prevent injury to the user's hands and feet. Target areas A-H are provided with an LED which illuminates when the user is to punch or kick a specific target area. Electronic control unit 26 provides several skill levels which allow the user to evaluate his or her progress and performance.

Accordingly, the improved kick-boxing exercise device is simplified, provides an effective, safe, inexpensive, and efficient device which achieves all the enumerated objectives, provides for eliminating difficulties encountered with prior S 10 devices, and solves problems and obtains new results in the art.
