DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pitching machine used for a baseball game or toss batting practice. The present invention relates to a pitching machine which can be used for actual battles, thereby eliminating physical growth stoppage caused by unreasonable pitching particularly in juvenile baseball. Or to reduce the physical wasting of relatively elderly people.

[0002]

2. Description of the Related Art A hitherto known pitching apparatus includes:
A launching means for launching the ball in a predetermined external direction from a launching window of the case body, and a linear shooter for stocking the ball and sequentially feeding the ball into the case body having the launching means, It is mainly used for batting center and baseball toss practice.

[0003]

However, in the above-described conventional pitching apparatus, since a linear shooter is extended and bulky behind the case body,
Not only is stability inferior and it is easy to fall, but also for actual baseball, for example, there is a danger that the defender moves forward and hits the shooter of the pitcher when the batter bunts, and the pitch between the first baseman and the third baseman is the thrower. It could not be used except for the practice of batting due to the problem of easy hitting of the shooter.

[0004] Recently, it has become clear that full-scale pitching of elementary and junior high school children in baseball by growing children in baseball tends to hurt their shoulders and hinder proper growth as a baseball pitcher. In this sense, there has been a demand for a pitching machine to replace children.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention solves the above-mentioned various problems in the prior art and eliminates the bulk of the shooter to make the entire pitching apparatus compact, so that the actual baseball game can be performed. By enabling the use of, especially elementary and junior high school students in baseball,
It is designed to prevent a child's proper growth as a baseball pitcher from being hindered.Specifically, it is installed in the case main body and the case main body, and the ball is directed from the firing window to a certain external direction outside. It consists of a firing means for firing and a shooter for sequentially supplying balls into the case body, and the shooter is attached by being curved in a direction surrounding the case body while gradually increasing the altitude from a ball supply port into the case body. The present invention relates to a pitching machine.

According to another aspect of the present invention, there is provided a case body, a launching means installed in the case body, which launches a ball from an emission window in a predetermined external direction, and a shooter for sequentially supplying the ball into the case body. A pitching machine characterized in that the shooter is gradually increased in altitude from a ball supply port into the case body, is curved in a direction surrounding the case body, and the curved portion is attached to the case body side while being inclined. Related to

[0007]

[Function] When a large number of balls are placed on the shooter surrounding the case body, the balls roll sequentially on the shooter,
One by one enters the case main body from the ball supply port in a curved detour around the rear part of the case main body, and is fired in a predetermined external direction from the firing window by the firing means. In this case, if a receiving device (not shown) is built in the case main body and the launching means is activated by remote control from a remote position, the practicality is further increased. Further, when the curved portion of the shooter is attached to the case body so as to be inclined, the rolling of the ball on the shooter is further smoothed.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The specific contents of the present invention will be described below with reference to the illustrated embodiment. The launching means 15 for launching a ball toward the ball indicates a shooter for sequentially supplying the ball into the case body.
The case body 1 has a ball guide plate 3 which has a launch window 2 opened in the front and is slightly curved toward the launch window 2.
In addition, a ball supply port 4 for supplying a ball onto the ball guide plate 3 is formed on the left side of the case body 1. 16 is the ball B from the shooter 15
And 17 denotes a lower cover surrounding the ball supply port 4.

Further, a circular projection 5 is formed at an upper portion in the case body 1 so as to protrude horizontally from one wall surface to the other wall surface, and a handle portion 6 is provided at an upper end portion of the case body 1. Further, a screw type height adjusting device 7 is attached to the bottom near the front. The firing means 8 is formed by folding a metal spring round bar in a U-shape with a slight interval (about 1.5 to 2.8 cm) on the side approaching the ball guide plate 3 to form two parallel metal bars. The eccentric cam 14 operates the pitch spring 9 by a spring round bar, the eccentric cam 14 for operating the pitch spring 9, and the reduction gear 13 coaxial with the eccentric cam 14.

The pitching spring 9 has a coil spring portion 9a wound in a coil shape on each of the above-mentioned two parallel metal spring round bars in the base direction thereof, and has a longer length than the coil spring portion 9a. At a position near the center, the metal spring round bar is recessed on one side, a roller shaft 12 supporting a roller 10 is supported in the recessed portion, and the roller shaft 12 is stopped by a stop spring 11, so that the left and right 2 The roller 10 is rotatably held between the metal spring round bars.

Further, the pitching spring 9 has a base end portion fixed to an upper portion of the case body 1 and a coil spring portion 9a held by the projection 5 to receive a biasing force of the case body 1 to the back. In this case, the projection 5 is supported as a fulcrum so that the distal end thereof can move toward the back (to the rear of the case body 1) substantially along the ball guide plate 3 against its elastic force, The portion is urged to be located in the direction of the launch window 2. The eccentric cam 14 is centered on the rotating shaft 12 having both ends supported on the side wall surface of the case body 1, and a specific position (0 degree) in the rotational direction angle is set to the small diameter portion 14 a.
In this case, the diameter is gradually increased gradually in the circumferential direction from the small-diameter portion 14a, and the position at the rotation direction angle of 360 degrees is the largest diameter portion 14b having the largest diameter.
The 60-degree portion is connected by a falling wall 14c.

The eccentric cam 14 is provided with the above-described throwing spring 9.
2 and a reduction gear 13 coaxially and integrally mounted with the roller 10 and a drive gear G meshing with the reduction gear 13, the motor M With the above driving force, the reduction gear 13 and the eccentric cam 14 can be rotated at a constant speed in the direction of the arrow in FIG.

Further, the shooter 15 has a base end 15.
a ball supply port 4 formed on one side surface of case body 1
To form a curved portion 15b by gradually bending the ball from the ball supply port 4 in the direction surrounding the rear portion of the case body 1 while gradually increasing the height from the ground contact surface.
After wrapping around the rear part of the case body 1, the tip part 15 c is turned back and along the side surface on the opposite side of the case body 1 so that the tip part 15 c is located closer to the front on the opposite side of the case body 1, and the tip part 15 c
Can be supplied with the ball B.

In this case, the bending portion 1
5b is attached to the case body 1 side so as to be higher on the A1 side than on the A side in the cross section A-A1, so that the ball B can pass through the curved portion 15b more smoothly. In addition, it is possible to eliminate ball clogging. As for the cross-sectional shape of the shooter 15, a passage having sufficient space for rolling can be formed while the ball B can be accommodated. The bottom of the passage is flat or slightly curved, and the left and right sides are formed. It is preferable that the surface has a rising wall surface, and the cross section is configured to be substantially U-shaped. However, the cross section may be substantially V-shaped or cylindrical.

In the above configuration, when the ball B is placed on the tip 15c of the shooter, the ball B goes around the rear portion of the case body 1 along the curved portion 15b from the shooter tip 15c, Along the base end 15a, falls from the upper cover 16 into the lower cover 17, and falls one by one from the ball supply port 4 to the case body 1.
Get on the ball guide plate 3 inside. On the other hand, when a pitcher or a coacher behind the pitching machine emits a firing signal by remote control, a receiving device (not shown) in the case body 1 receives the signal and drives the motor M to drive the driving gear. G causes the reduction gear 13 to rotate at a constant speed in the direction of the arrow in FIG.

When the reduction gear 13 starts rotating from the state shown in FIG. 2, the eccentric cam 14 coaxial therewith also rotates, and the small diameter portion 14a of the eccentric cam 14 comes into contact with the roller 10 and the large diameter portion 14a.
As the rotation proceeds in the direction b, the rotation shaft 12 of the eccentric cam 14
The pitching spring 9 is deformed toward the back (rear) of the case body 1 against the elastic force while the roller 10 rolls on the eccentric cam 14 with this. When the contact position of the roller 10 reaches the final large-diameter portion 14b, the roller B is located at a portion indicated by a chain line in FIG. 2, and accordingly, the ball B is also lowered along the ball guide plate 3 in FIG. Reach position.

The motor M continues to rotate, and the eccentric cam 14
The roller 10 on the large-diameter portion 14b is immediately separated from the large-diameter portion 14b, and slides down in the direction of the small-diameter portion 14a along the falling wall 14c. Roller 10 at that moment
Is released, and the throwing spring 9 is moved by the original elastic force into the firing window 2.
The ball B, which has been vigorously restored in the direction, is sent out along the ball guide plate 3 at the position indicated by the dashed line in FIG. 2, and is emitted from the emission window 2 in a fixed outward direction. After firing, when the drum 13 is in the state shown in FIG. 2, the motor M is automatically stopped to prepare for the next firing signal, and the next ball enters the lower cover and waits. Shooter 1
5, when the ball B passes through the curved portion 15b, the rolling resistance with respect to the outer peripheral side wall surface is reduced,
The rolling of the ball becomes smoother.
