FIELD AND BACKGROUND OF THE INVENTION
1. Field
The following description relates to a multi-purpose exercise apparatus for improving sports coordination, and more particularly, to a new type of multi-purpose exercise apparatus for exercising sports coordination with which a user may sense stimuli from inside and outside one's body and at the same time operate one's body functions so as to adapt to the given circumstances using body muscles when playing a football, volleyball, handball, tennis, table tennis game and the like, thereby improving abilities of adjusting one's body parts such as the user's correct posture, balance, timing, flexibility, agility and the like.
2. Description of Related Art
Generally, it is the fundamental of all exercises and sports to expect at least a certain exercising effect from all the organs of movement of a human body making harmonious movements while maintaining adjustable relationships between one another.
In science terms, ‘Coordination’ refers to the harmonious interaction between sensory organs, end organs and central nervous systems, and skeletal muscle organs. Thus, a sports coordination exercise consisting of continuous movements aims at enabling the muscles suitable to the right timing and circumstances to act on one another.
Sports coordination refers to a body adjusting ability of enabling the exact amount of muscles necessary for making movements in the right timing to function consciously or unconsciously in the method desired or wanted by the sports participant. That is, sports coordination is the ability to support all parts of the body muscles to move simultaneously at the right timing.
Therefore, coordination exercise includes using various body systems and motion types that form individual actions and technique necessary for performing a certain movement.
Coordination exercise is a core function that people and athletes intending to enjoy various sports and exercises need, and an exact coordination exercise provides a synergy effect by way of effective movements and the brain for efficient utilization of muscles.
Especially, sports coordination exercise is most needed in sports games where players use a ball, and the exercise for improving body adjustment abilities is an exercise most needed for children and teenagers or sports participants who use balls.
In a sports game using a ball, one's body ability to efficiently move all parts of his/her body including arms, legs, pelvis, waist and shoulders according to the commands sent from the brain based on sensory judgment of the person makes the person move one step faster than others.
Furthermore, since coordination exercise helps all body muscles and nervous systems to be prepared for the main exercise, not only does it significantly improves the ability to acquire the exercise but it may also be used as a preliminary exercising process to prevent various types of injuries from occurring during an extreme exercise (neuromuscle exercise).
For example, when playing football, players have to move constantly, and when a player is approached by a ball, the transition to the right posture to control the ball perfectly must be made in a very short period of time.
The player will have to lower centroid of his/her body, decide which body part to use and in which direction to move, and make a weight-shift by stepping up. Furthermore, if there is a defender, the player has to use the arms, back and shoulders in addition. Therefore, a bunch of movements must be made in a very short moment. It is the sports coordination exercise that makes these preparations more precise and faster.
Traditional coordination exercises use various types of exercising equipments (large ball, cone, bar, exercising ladder), but these exercises require the players to repeat the same movements over and over again, making the players get bored and find it hard to keep concentrated on and maintain interest in the game.
Especially, monotonous coordination exercises for adults with degenerating sports abilities being provided when their flexibility, sense of balance and agility are deteriorating is less effective and thus does not develop into continuous exercises.
Furthermore, strengthening muscles using fitness equipments or doing aerobic exercises by simply running may exacerbate imbalance of the participant body, and impede a harmonious development of all parts of the body.
Besides, many athletes and sports participants want to maintain their body balance and shape using all parts of their body effectively, but there has been no proposed apparatus or equipment proposed that could help people exercise their all body parts evenly while improving their body adjustment abilities.

The wheel 60 is a tube type wheel that may be used both indoors and outdoors. Furthermore, it may be a type of wheel with sufficient height and size to move with ease even in playgrounds made of grass or rough soil.
Meanwhile, a locking unit 70 is further installed between each wheel 60 and fixing frame 50. The locking unit 70 includes a locking lever 71 configured to penetrate along the center of the rotation axis of the wheel and to be screw-coupled to the fixing frame 50 so as to move in an inner/outer direction of the wheel 60 during rotation, a first locking member 72 coupled to an exterior of the lever and configured to rotate in an interlocked manner with the locking lever 71 as the locking lever 71 rotates, and a second locking member 73 coupled to the fixing frame 50 and installed to be geared to the first locking member 72.
The second locking member 73 is provided with a protruding end 73a, and the first locking member 72 is provided with an insertion hole 72a where the protruding end 73a is inserted.
That is, as illustrated in FIG. 14, when the locking lever 71 is rotated clockwise so that it moves in an inner direction of the wheel 60, the protruding end 73a of the second locking member 73 is inserted into the insertion hole 72a of the first locking member 72, thereby fixing the wheel 60.
Likewise, when the locking lever 71 is rotated counterclockwise, the locking of the wheel 60 may be released.
FIG. 15 is a view illustrating details of a portion of FIG. 13. Referring to FIG. 15, on the fixing frame 50, any one of the two wheels 60 distanced to secure ease of motion may be rotatable. That is, the fixing wheel 50 is separately formed to consist of two parts: a first part frame 51 and a second part frame 52, and these two separated parts are hinge-coupled through a pin 53. Each part frame is separately formed such that a wheel is installed thereon, respectively.
By doing this, as illustrated in FIG. 16, when moving by the wheel 60, it is possible to vary the proceeding direction of the wheel 60 in any direction, thereby securing ease of motion.
FIG. 17 is a view illustrating details of a net unit of FIG. 1. Referring to FIG. 17, the net unit 80 includes a net 81, net pole 82, and coupling member 83.

The net pole 82 is coupled to the net 81 at both longitudinal ends of the net 81. Herein, the net pole 81 may be formed to have a shape of an antenna such that the height of the net 81 is adjustable.
There are one pair of coupling members 83 into which both sides of the first playing plane 11 and second playing plane 12 are inserted and coupled by a predetermined bolt, and net poles 82 are coupled on top of the coupling members 83.
That is, as illustrated in FIG. 18, by moving the net poles 82 and fixing bar 81a, the height of the net 81 may be adjusted.
When using a multi-purpose exercise apparatus for improving sports coordination according to the aforementioned present disclosure, it is possible to improve the instant judgment ability and predictability suitable to momentary situations, and induce development of the perception ability and sensing ability based on immediate interaction between body parts according to instructions from the brain.
Furthermore, in the case of a football technique exercise, when sending a ball to a certain position intended by the user with a portion or an entirety of the table fixed vertically to form a wall, it is possible to perform an exact kick and a quick control on the rebounded ball, thereby acquiring the effect of improving the instant speed and the ability of converting the proceeding direction of the ball.
Furthermore, it is also possible to induce a situation to exercise the body adjustment ability of the highest difficulty level by forming a net with a vertical wall as in volleyball such that the ball may be moved only in the air, thereby bringing out the highest body adjustment ability to handle balls in the air of which the height and changes tend to be excessive.
