Apparatus of ball supply for batting practice}

The present invention relates to a ball supplying device for tee betting to continuously supply the ball to the other at a predetermined height and speed and a predetermined time interval through the ball formed in the housing supplied to the housing having a predetermined receiving space, In particular, the tee is a slow enough to be batter tee batting tee to allow continuous supply at regular intervals, and at the same time to adjust the height of the ball supplied according to the batter's blow height, so that you can practice batting alone It relates to a ball supply device for betting.

In general, the batter of a baseball player makes a tee bet to practice and correct the batting posture. The tee bet consists of a pair of people who lightly throw the ball to the side and a person who strikes the ball lightly.

Here, the tee bet is made for the batting posture correction that can hit the ball when the batter hits the ball, the maximum force is transferred to the bat at the batting position, in particular, during rainy weather or in winter when the outdoor environment is poor This is the practice method you are using.

As described above, this tee bet is mainly an indoor exercise, and winter training is mostly planned for this tee bet.

Therefore, conventionally, in order to make a tee bet, one person must continuously supply the ball by the side of the hitting exerciser, and since a certain amount of practice passes, the person supplying the ball and the person practicing hitting alternately to make the tee betting. Since the batter who finished the batting practice has to rest for a certain amount of time because the batter is exhausted, a predetermined time flows insignificantly, thus causing a waste of time for the individual.

In addition, since the bet must be made by alternation, one person cannot achieve continuous betting and, of course, the ball supply by the person cannot maintain a constant height, and the ball is supplied irregularly so that the hitting point can be specified in one posture. There was a problem that is very difficult to correct the blow foam.

The present invention has been devised to solve the above problems, one person betting tea be a set of one to allow the ball to be supplied at a constant height in accordance with the height and hitting point of the batter at the same time to give a predetermined time continuously It serves the purpose of allowing the ball to be fed.

Hereinafter, the configuration and operation of the present invention will be described in Figures 1 to 5.

First, the body frame 103 is embedded in the housing 101 having a predetermined accommodation space as shown in FIG. 1, and the driving wheel 105 is vertically disposed on the body frame 103, and the body frame 103 is disposed. The drive wheel shaft 105a is freely installed in the bearing block 104 installed in the rotation block.

Here, the outer diameter surface of the drive wheel 105 is urethane resin having a coefficient of friction enough to be able to bounce the ball well when it is rotated by the drive motor 109 to be described later and the ball is supplied to the outer appearance.

On the other hand, the interlocking pulley 106 is installed on the other drive wheel shaft 105a of the drive wheel 105, the drive pulley 108 and the belt ( 107, the rotational force of the drive motor 109 is transmitted in the order of the drive pulley 108, belt 107, the interlocking pulley 106, the drive wheel shaft 105a and finally drive wheel 105 Rotated.

Here, before the driving wheel shaft 105a is formed on the bearing block 104, the guide panel 110 having a predetermined length and width is inserted into both driving wheel shafts 105a and disposed upward, as shown in FIG. Bar, the guide panel 110 has a relatively smaller outer diameter than the driving wheel 105, the urethane resin is formed on the outer diameter surface of the outer wheel height adjustment wheel 111 is freely coupled.

Therefore, when the driving wheel 105 is rotated to the front, the ball is supplied to the upper rear of the driving wheel 105 through the guide hole 112 to be described later, the driving wheel 105 is the rotational force to the ball As shown in FIG. 2, the ball is bounced by the driving wheel 105 and at the same time the bounced direction is set to the front while being in contact with the height adjusting wheel 111, wherein the ball is the height adjusting wheel. The 111 is bounced out while rotating in the opposite direction of the driving wheel 105.

In addition, the ball bounced off by the rotation of the driving wheel 105 is decelerated by the height adjusting wheel 111 and at the same time the height adjusting wheel 111 is bounced according to the positions disposed before and behind the driving wheel 105. The height of the outgoing ball is also determined as shown in FIG.

Here, by placing the height adjustment wheel 111 in front of, behind the drive wheel 105, the rotation means of the height adjustment wheel for adjusting the height of the ball, is coupled to the upper end of the both side guide panel 110 Coupled to the rotating hole 115 to be rotated in the rotational direction of the driving wheel 105 to the upper bracket 114 coupled to a predetermined position of the upper panel 113, the driving wheel 105 to the rotating hole 115 A screw hole 115a is formed in parallel with the rotational direction of the screw hole 115a, and the screw rod 117 through which the rotor is freely coupled to the housing 101 at a predetermined position is fastened to the screw hole 115a.

Accordingly, as the operating lever 116 formed at the rear end of the screw rod 117 (outside of the housing 101) rotates, the turning hole 115 moves forward along the thread of the screw rod 117 (drive wheel ( 105) and rearward (reverse rotation direction of the driving wheel 105), the guide panel 110 is rotated and advanced as shown in FIG. 2 around the driving wheel shaft 105a. , Height adjustment wheel 111 is also rotated and advanced.

At this time, the screw rod 117 may also be inclined upward and downward according to the rotation of the turning hole 115, but since the angle is very fine, an excessive force is applied to the screw rod 117 coupled to the housing 101. You won't lose.

On the other hand, when the ball bounced forward by the driving wheel 105 and passes through the through hole 102 is in contact with the height adjustment wheel 111, the height adjustment wheel by the rotational force and the speed of the ball to be bounced out A predetermined magnitude of impact is applied to the 111.

At this time, when looking at the buffer means of the height adjustment wheel to absorb and dissipate the shock received by the height adjustment wheel 111 as much as possible, the center axis 111a of the height adjustment wheel 111 is upper The long hole 120 is formed to a predetermined length so that it can be transferred to, and the support bracket 121 is installed in the lower part of the long hole 120 as shown in FIGS. 1 and 2.

In addition, the guide rods 122 are coupled to the extension portions 113a extending from both sides of the support bracket 121 and the upper panel 113, respectively.

In addition, the guide rod 122 is inserted into the lifting hole 123 so that the lifting hole 123 can be lowered along the guide rod 122, the lifting hole 123 has a central axis (111a) When combined with the height adjustment wheel 111 to try to ascend by impact from the ball, the lifting hole (123) to be able to move along the guide rod 122.

In addition, a first elastic member 124 is inserted into the guide rod 122 positioned between the upper portion of the elevating hole 123 and the extension portion 113a of the upper panel 113 so as to elastically support the elevating hole 123. As a result, the first elastic member 124 absorbs and distributes the force of the lifting lowering hole 123, and at the same time, the lifting lowering hole 123 is lowered by the elastic repulsive force and moved to its original position. The ball continuously supplied to the wheel 105 is continuously bounced out by the driving wheel 105 and the height adjusting wheel 111.

On the other hand, the ball is bounced out by the driving wheel 105 and the height adjustment wheel 111 and at the same time the impact is absorbed and dispersed by the lifting hole 123 and the first elastic member 124, the height adjustment wheel ( 111 is continuously rotated by the frictional force with the ball, when the ball is bounced off by the driving wheel 105 in the state in which the height adjustment wheel 111 is rotated outer diameter surface of the ball and height adjustment wheel 111 Since the frictional resistance with and decreases the speed reduction efficiency of the ball, it is necessary to stop this rotation when the height adjustment wheel 111 is rotated.

Therefore, in the embodiment of the present invention, as shown in Figure 4 by providing a coupling with a lining 125 is formed on the inner peripheral surface of the central axis 111a above and below the central axis 111a of the height adjustment wheel 111 As the outer coupling, the lower coupling 126 is externally fixed at the lower portion of the central axis 111a and fixed to the inside of the guide panel 110.

Here, it is possible to outer-coupling the coupling on the central shaft 111a, but in order to increase the frictional force with the lining 125, a drum 130 having an outer diameter of a predetermined size is formed on the central shaft 111a so that the lining 125 and It is desirable to maximize the contact area.

Accordingly, the upper coupling 127 and the lower coupling 126 which are wound on the upper and lower portions of the central axis 111a or the drum 130 are illustrated in FIG. 5 by the through bolt 128a and the nut 128b.

When the 111 or the drum 130 moves up and down together with the height adjusting wheel 111, the lining 125 of the upper coupling 127 is the central axis due to the repulsive force generated while the second elastic member 129 is compressed. 111a) or the drum 130 is pressed (to be rubbed) to reduce the rotational force of the central axis 111a or the drum 130.

On the other hand, the body frame 103 located at the rear of the driving wheel 105 has a guide 112 of the '' 'cross section so that the ball supplied can be guided to the outer diameter surface of the rotating driving wheel 105 The guide bracket 131 is installed on the guide bracket 131 at a predetermined inclination, and the guide port 112 is provided with a ball supply means for supplying the balls continuously fed one by one at a predetermined time period.

The supply means of the ball is provided with a solenoid 119 at predetermined intervals on one side of the guide port 112, so that the stopper 118 coupled to the solenoid 119 penetrates into the guide port 112 inside. As shown in FIG. 3, one ball may be stopped on one stopper 118.

In addition, each of the two solenoids 119 is provided with a controller (not shown) for controlling power to be applied at intervals of a predetermined time in the housing 101 at a predetermined position.

Thus, as shown in FIG. 3A, the ball located at the top end is stopped by the first stopper 118a, and the ball after the ball is stopped by the second stopper 118b.

When power is applied to the first solenoid 119a by the control of the controller, the first stopper 118a is withdrawn by the electromagnetic force of the first solenoid 119a as shown in FIG. 3B, and at the same time, the first stopper The ball held by the stop 118a is supplied to the driving wheel 105 along this inclined surface because the guide 112 is inclined toward the driving wheel 105 side.

In addition, after a predetermined time elapses after the ball is supplied as shown in FIG. 3B, as the power supplied to the first solenoid 119a is cut off, the first stopper 118a is again drawn out as shown in FIG. 3C. The controller applies power to the second solenoid 119b so that the second stopper 118b is withdrawn to the second solenoid 119b as shown in Fig. 3d, so that the ball held by the second stopper 118b is stopped. It can be guided to the first stopper (118a).

Accordingly, the subsequent ball is stopped at the first stopper 118a, and the controller cuts off the power applied to the second solenoid 119b to allow the second stopper 118b to be drawn out, thereby allowing the subsequent ball to be seconded. By allowing the stopper 118b to be stopped as shown in FIG. 3A, the balls continuously fed are guided to the driving wheel 105 at predetermined intervals, thereby allowing the ball to bounce off the driving wheel 105 for a predetermined time. It is supplied to the batter one by one in a cycle.

On the other hand, the present invention is not limited to the ball supply device for supplying a predetermined amount of balls to the guide hole 112, preferably as shown in Figure 1 guide drum 140 of a predetermined size By installing the guide rail 141 in a spiral shape in the housing 101 and the ball can roll on the outer circumferential surface, and the end of the guide rail 141 can be disposed at the rear of the guide 112 The balls placed on the guide rails 141 are rolled downward one by one by the sequential supply by the guide holes 112 to guide the balls to the guide holes 112.

In addition, in the case where the ball placed on the guide rail 141 of the first and second solenoids 119a and 119b is stopped at the guide rail 141, the guide drum 140 is shown in FIG. As described above, the vibration piece 142 is attached to the guide drum 140, and the lower end of the vibration piece 142 is connected to the vibration solenoid 143 installed at a predetermined position of the guide bracket 131 by the connector 144. At the same time as the power supply of the second solenoid 119, the vibrating solenoid 119 pulls and releases the connector as shown in FIG. 5 and vibrates the guide drum 140 while the ball is placed on the guide rail 141. It is desirable to be able to roll smoothly to the lower portion by vibration.

As described above, the present invention provides the same effect as throwing a ball at a slow speed by a colleague who is teeing a batter, and the height is constantly supplied to the batter so that the hitting point is consistently quick. In addition to allowing a striking posture, if the winter or outdoor environment is poor, even in a narrow indoor space can be tee bet alone.
