Here, the front grasping plate 430 and the rear grasping plate 440 are preferably made of a sponge or a urethane material because they can be accidentally hit against a hand when practicing spikes.

The ball plotter 500 is for throwing a volley ball rolling down along the guide table 300 in the air and hitting a moving ball so as to practice spikes or to perform a toss and a receiving exercise. The ball plotter 500 includes a side support 510 and a floor support 530 ). That is, the side support 510 is disposed so that the left side corresponding to the left side guide bar 302 of the guide base 300 and the right side corresponding to the right side guide bar 304 of the guide base 300 are spaced apart from each other, The shape of the side support 510 is such that a rod coupling hole 520 corresponding to the coupling rod 310 of the guide base 300 is inserted into the horizontal portion 512 formed at the rear end portion and the horizontal portion 512 formed upward at the tip of the horizontal portion 512 And an inclined portion 514 inclined and integrally formed. Between the side supports 510, a bottom support 530 is installed in parallel with the side support 510 so that the vowel does not come off. Therefore, when a volley ball rolling down along the guide base 300 reaches the ball floater 500, the ball player is guided upward along the slope portion 514 at the speed to throw the ball into the air.

5 and 6, the stopper means is additionally provided so that one of the volute holes guided along the guide base 300 can be selectively guided.

The stopper means includes a stopper for spikes 700 used for spike exercises together with the ball catcher 400 and a floater stopper 800 used for spike, toss, and receive exercises together with the ball floater 500 Respectively.

The spike stopper 700 includes a center bar 720 horizontally disposed in front of the guide bar 300, a stopper plate 710 rotatably installed at the center bar 720 and erected upward at an angle, The operation bar 730 is connected to the operation bar 730 and the other end is connected to a part of the guide bar 300 so that the operation bar 730 is in a standing state And a spike string 750 connected to a lower portion of the operation bar 730 and used to pull the operation bar 730 backward. Therefore, since the stopper plate 710 is kept in a standing state by the restoring spring 740 at first, a state in which the ball bearing moving along the guide base 300 is not caught by the stopper plate 710 is maintained When the spike string 750 is pulled out, the operation bar 730 moves rearward, and relatively the stopper plate 710 falls forward, so that the volleyball can be moved.

The stopper 800 for a floater includes a stopper mounting bracket 810 provided at the rear lower portion of the guide base 300, a stopper pin case 820 provided at the bottom of the stopper mounting bracket 810, a stopper pin case 820 The upper end of the stopper pin 830 extends through the stopper mounting bracket 810 and extends to the upper portion of the guide base 300.

The stopper pin 830 protrudes upward from the guide base 300 by the resilient spring 850 so as to prevent the ball from being caught by the swinging pin so that the stopper pin 860 is pulled, 830 move down so that the ball can be moved.

Now, the operation of the multifunctional volleyball training apparatus according to the present invention will be described.

First, when the ball catcher 400 is installed on the guide base 300 and the spikes are practiced, the ball carriers are guided one by one using the stopper 700 for spikes. 7, the stopper plate 710 is engaged with the ball bearing hole of the guide base 300, so that the guide hole of the guide base 300 is engaged with the stopper plate 710, ) Standing on the line. When the spike string 750 is pulled in this state, the operation bar 730 rotates to the rear of the guide base 300 as shown by the imaginary line in FIG. 5, and at the same time, the stopper plate 710 is inclined forward The topmost volleyball moves to the catcher 400 over the stopper plate 710 so that the volleyball moves between the front grip plate 430 of the ball catcher 400 and the rear grip plate 440 And remains floating in the air. Of course, when one of the volleyballs moves, the spike line 750 is pulled. Then, the restoring spring 740 moves the operating bar 730 back to the original position, and the stopper plate 710 is raised to restrict the movement of the next vlet. Therefore, it becomes possible to guide the ball players one by one to the ball catcher 400. [ Of course, when a volleyball is caught between the front grip plate 430 and the rear grip plate 440 of the ball catcher 400, the volleyball practitioner hits the volleyball while jumping and performs the spike exercise. Particularly, when the coach grips the spike line 750 and adjusts the movement of the volleyball, a plurality of volleyball practitioners can stand and practice the spike while riding in sequence. For reference, when the spike stopper 700 is used, it is required that the floater stopper 800 is kept in a state in which the balloon can pass.

Next, when the ball plotter 500 is installed on the guide table 300 and spikes, tosses, and receivings are practiced, the volute holes are guided one by one using the plotter stopper 800. Namely, the ball in the ball insertion nail 200 is guided to the rear of the guide base 300 through the ball outlet 204 and is held by the stopper pin 830 as shown in Fig. 9 . When the plotter strand 860 is pulled in this state, the stopper pin 830 descends into the stopper pin case 820 as shown by a phantom line in FIG. 6, (300). Of course, when one of the volleyballs moves along the guide table 300, the plotter line 860 is pulled out and the stopper pin 830 is raised upward by the restoring force of the elastic spring 850, Do not allow the volleyball to move. As a result, the volleyball player moves forward along the sloping portion 514 of the ball plotter 500 and is thrown upward. Thus, the volleyball practitioner hits the running volleyball with the palm of his hand to perform the spike training Or, you can practice toss or receive under the ball plotter 500. In this practice, several volleyball practitioners can practice in sequence as the coach grabs the plotter line (860) and adjusts the movement of the volleyball. For reference, when the floater stopper 800 is used, it is required that the spike stopper 700 be kept in a state in which the volleyball can pass.

The speed of the volley ball to be thrown during the volleyball practice may be determined by adjusting the inclination angle of the guide base 300 through the angle adjusting means as shown in Figs. 11 and 12. That is, the angle of the guide base 300 is set such that the screw rod 660 is contracted or extended into the rotation bar 670 in accordance with the rotation direction of the rotation bar 670, And the angle of the guide base 300 connected to the fixing bracket 630 is adjusted. Therefore, if the slope is urgent, the transfer speed of the volleyball is accelerated and the volleyball is thrown strongly. If the slope is slow, the transfer speed of the volleyball is slowed and the volleyball is weakly thrown.

While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Anyone who can afford it will know.
