DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which a tosser normally throws up a toss ball, and the batting practitioner hits the toss ball. This is a technique related to a toss batting pitcher that throws up a ball.

[0002]

2. Description of the Related Art Japanese Patent Application No. 10-357 by the same applicant.
No. 974 (Japanese Unexamined Patent Publication No. 2000-176071) has filed an invention relating to a toss batting pitcher.

[0003]

However, the conventional toss batting throwing apparatus has the following disadvantages and has not been explosively popularized in the world. First, in the drive mechanism of the toss arm, the end is swingably supported at the long hole, so that it takes time to store the energy of the biasing spring in the toss arm. Because the pitch was long, the pitching interval was long once every 6 seconds, and the pitching interval was about once every 3.5 seconds when a normal assistant tossed and tossed batting. There is a problem in that the interval is too large between the return of the bat to the original position after one hit and the next hit, making it difficult to take timing. In addition, since it is different from toss batting by a normal assistant, there is also a problem that it is difficult to practice. Secondly, a chain is used as a mechanism for driving the toss arm from the geared motor, and the toss arm is also not pivotally supported on the shaft, so that it is necessary to make the overall structure robust and the weight is 80%.
It was very heavy, weighing a kilo, was expensive, expensive, and could not be moved easily. Third, since the side opposite to the ball holding portion of the toss arm is a mechanism that swings up and down, the form of throwing the ball is a throw-up like a shot put, such that a normal person throws a toss ball. However, there was a problem that the ball could not be thrown from below with a snap-throw-shaped ball streak giving rotation with a fingertip. Fourth, an electric circuit and components such as a switch and a solenoid are used as an opening / closing mechanism of a stopper for enabling the ball stored in the ball holding rail to move to the ball holding portion. In parts, electrical failures are likely to occur,
There was a problem that it took time and money for maintenance.

[0008] In the conventional toss batting pitcher, the pitch of the ball is about 6 seconds. Therefore, the waiting time is long, and after hitting, it is not possible to start the operation of hitting the next hit ball immediately after pulling the bat, and it is necessary to make a swing to wait for time between, Well, it was not possible to continuously perform toss batting one after another. In normal toss batting, there is an assistant, and the interval at which the toss ball is lifted is such that the batter hits the bat, pulls the bat, and then throws up the ball in accordance with the interval of moving to the next toss batting. Approximately this interval was 3.5 seconds and 6 seconds was too long. Therefore, after hitting, 1, 2, 3, 4
Then, the optimal posture is 3.5 seconds after returning to the original posture, returning to the next striking posture, and performing the next striking.

In the present improvement, the toss batting pitcher is first improved in order to create the interval of 3.5 seconds. In the previous toss machine, it took too much time to twist up the spring to store the energy for turning the arm for pitching. In order to improve this point, the last time the lower end of the throwing arm was moved up and down in the long hole, this time, the lower end of the throwing arm is configured to rotate on the pivot shaft did. Further, the pitching arm itself was constituted by a leaf spring. Therefore, although the pitching arm rotates around the pivot shaft, the lower end does not move up and down inside the elongated hole.

In a conventional configuration in which a pitching arm is rotated by the energy of a spring while moving up and down in a long hole,
This is a pitching operation like a shot put, and the ball holding portion may be an arcuate ring, but in the present invention, it is a pitching operation by a pitching arm with a snap effect. The ball holding portion 2 of the toss arm 1 is of a lower throw snap throw type. In this way, the required power could be reduced by making the snap throw from the operation of the shot put, so the motor could be made smaller, and the motor became smaller, so the whole became simpler , Which used to be 85 kg in weight,
It could be reduced to about 0 kilograms. As a result, the selling price was reduced from the price of 400,000 yen to about 280,000 yen.

In the conventional model, power is transmitted from a motor by a belt. However, in this case, a chain drive can be eliminated by using a geared motor. That is, direct drive by a geared motor could be performed. In addition, since the throw is a snap throw, if the ball holding portion is formed in an arc shape, there is a problem that the direction of the ball is not constant. In this improvement, the ball holding portion is provided with two protrusions in the vertical direction, which take the place of two fingers, so that in the snap throw,
It is configured to stabilize pitching. In the prior application of the same applicant, since the ball a was thrown with the capacity of the shot put, the direction of the ball was not unstable, rather than a snap throw. Further, two standby rails for spare balls are configured, and a mechanism for alternately extracting the left and right balls from the two rails is configured to also be driven by the above-described geared motor. Also,
The angle at which the ball is thrown can be changed by changing the range of the angle of rotation of the throwing arm. This allows
It is possible to change and adjust in seven steps, such as throwing a high ball or a low ball.

Further, the support portion of the base frame is constituted by two caster wheels and two support portions, and when the body is tilted, traveling movement by the two caster wheels can be performed. By using the snap throw, it is now possible to throw a ball of the same quality as the pitcher's pitching motion, which is different from the previous shot put. In addition, since the pitching energy is accumulated by both the leaf spring of the pitching arm and the coil spring for energy storage, it is possible to throw a quick ball in a state close to the pitcher's snap throw while being small and low power. Became. A geared motor is arranged below the ball waiting rail, making it a compact configuration.

Referring to FIG. 1, the construction of the batter B and the toss batting pitcher of the present invention will be described. This toss batting pitcher is basically capable of toss batting by the batter B operating alone without the need of an assistant, and the batter B presses the main switch S provided on the fuselage. Since it is dangerous that the ball a is thrown while moving to the hitting position, the spring drive arm 4 is configured so that the ball a is not supplied when the first toss arm 1 performs the pitching operation. And the locking position of the pitching force urging spring 5 is linked to each other. Also, set the main switch S to batter B
If the batter B stands in the striking position and then operates the main switch S at that position, it is safe from the first toss arm 1 pitching operation. May be configured so that toss batting can be performed.

Further, since the toss batting pitcher of the present invention is configured to weigh about 30 kg, the handle handle H is provided at the upper part so that the device can be moved alone by elementary school students to junior high school students. Is provided, and the body is tilted in the direction of the caster wheel 13 to float the mounting support 14 so that the body can be moved by pushing or pulling. In addition, a ball a
There is provided a storage frame 30 for charging the ball, and the storage frame 30 is followed by the ball holding rail 8.
The ball holding rail 8 is composed of two rails 8a and 8b. The ball holding rails 8a and 8b are configured side by side, and meander up and down so as to hold as many balls a as possible, so that the balls are overlapped. Thus, the ball stopper 19 can be supplied. Since a total of 30 to 40 balls a can be held in the ball holding rails 8a and 8b, continuous toss batting is possible until this number is lost.

The ball a, which has moved to the lower end in the ball holding rails 8a and 8b, moves one of the right and left balls through the guide gutter 44 by the ball stopper 19 rotated left and right. It is configured to be dropped and supplied to the ball holding section 2 at the tip of the waiting toss arm 1 and fitted. The geared motor 7 is arranged at a position below the ball holding rails 8a and 8b, and is arranged at a position for improving left-right stability. In FIG.
A side view on the side of the toss arm 1 is shown. A pitching direction adjusting lever 33 and a ball holding portion 2 are protruded from a portion of the decorative cover 32 covering the toss arm 1. A pitching opening 31 through which the ball a is thrown is opened at a position above the decorative cover 32.

FIG. 3 is a side view of the toss batting pitcher of the present invention on the side of the ball holding rails 8a and 8b.
A mounting support 14 and a caster wheel 13 are fixed to a lower portion of the frame 12. In addition, a handle handle H is provided on the upper part with the storage frame 30. FIG. 4 is a drawing showing a drive system from the geared motor 7 to the toss arm 1 and the ball stopper 19. In the drive system from the geared motor 7 to the toss arm 1, the drive shaft of the geared motor 7 is the pivot shaft 3 as it is, and the spring drive arm 4 is fixed to the tip of the drive shaft of the geared motor 7. The spring drive arm 4 is continuously rotated at a constant rotation speed of 360 degrees.

The geared motor 7 is provided with a reduction gear train therein, and reduces the rotation of the motor to output a predetermined low-speed rotation to a drive shaft (pivot shaft 3).
In the toss batting pitching device of the present invention, the spring drive arm 4 is rotated by the rotation of the drive shaft (pivot shaft 3) of the geared motor 7, and the spring drive arm 4 is locked by the pitching force biasing spring 5. One end of the pitching force biasing spring 5 is locked to the shaft 25 portion. And the other end of the pitching force biasing spring 5 is
It is locked by a spring locking plate 6 integrally provided with the toss arm 1. In the switching drive mechanism of the ball stopper 19, the spring drive arm 4 described above is formed in a cam shape, and the cam protrusion 4a and the cam flat portion 4b are formed. Since the position of the cam projection 4a and the position of the locking shaft 25 of the pitching force urging spring 5 are arranged on the opposite sides via the drive shaft (the pivot shaft 3), , Locking shaft 2
Only after the toss arm 1 has been pitched and rotated beyond the line beyond the fulcrum connecting the position of the toss arm 1 and the position of the drive shaft (pivot shaft 3), the switching projection 23 has the switching cam 22 most protruded. Beyond the section, the switching cam 22 is pushed to the opposite side to switch, the ball stopper 19 is rotated, and the first ball a can be guided to the guide gutter 44 and the ball a can be guided for the first time. It is. Thus, after the main switch S is turned on to throw the ball a at a short interval of 3.5 seconds, the ball a is no longer thrown at the batter B who attempts to move to the hitting position.

Referring to FIGS. 4, 5 and 6, the driving mechanism of the spring driving arm 4 will be described. The toss arm 1 only pivotally supports the base of its rotation on the aforementioned drive shaft (pivot shaft 3), and is not driven by the drive shaft (pivot shaft 3). With the rotation of the drive arm 4, the pitching force urging spring 5 is tensioned, and the spring drive arm 4 passes through the opposite side connecting the toss arm 1 and the drive shaft (the pivot shaft 3), and the fulcrum is over. Is generated, the tension energy stored in the pitching force biasing spring 5 causes the toss arm 1 to impact.
Is in contact with the lower rotation stopper 11 below,
It turns to the position where it contacts the upper turning stopper 10 at the top. At that moment, the ball a fitted into the ball holding portion 2 at the tip of the toss arm 1 is thrown out of the pitch opening 31 by centrifugal force.

In the conventional toss batting throwing apparatus, the toss arm 1 is thrown in a shot put situation where the lower end of the toss arm 1 moves up and down in a long hole, but in the present invention, the toss arm 1 is driven by a drive shaft (pivot shaft). Since it is thrown while rotating while being pivotally supported by 3), it becomes a snap-throw state. In particular, since the toss arm 1 is made of a steel plate, the toss arm 1 is momentarily bent,
Even with the short toss arm 1, it is possible to make a strong and fast pitch taking in the energy of the pitching force urging spring 5 sufficiently. When the toss arm 1 finishes pitching, the spring drive arm 4 rotates so as to approach the direction of the toss arm 1, so that the pitching force urging spring 5 is loosened and the toss arm 1 is released.
In FIG. 7, the spring locking plate 6 gradually lowers from the state in which the spring locking plate 6 contacts the upper rotation stopper 10, and returns to the state in which the spring locking plate 6 contacts the lower rotation stopper 11.

The spring locking plate 6 is a lower rotation stopper 11
When the spring drive arm 4 further rotates from the position where it contacts the toss arm, the position of the locking shaft 25 of the throwing force urging spring 5 moves below the toss arm 1 and then moves away from the toss arm 1 Then, the locking shaft 25 rotates, and the pitching force urging spring 5 is gradually pulled to a tension state. The extreme position of this tensioned tension state is the completely opposite position where the drive shaft (pivot shaft 3) of the toss arm 1 is arranged in the middle. 5 instantaneously attracts the toss arm 1 and pivotally rotates it by about 90 degrees. The repetition interval is set to about 3.5 seconds.

As shown in FIG. 5, the upper rotation stopper 10 and the lower rotation stopper 11 are fixed to both sides of the stopper support rods 36. The stopper support rods 36 are formed at an angle of about 80 to 100 degrees, and are formed at about 90 degrees in the embodiment. The stopper support rods 36 are pivotally supported by a drive shaft (pivot shaft 3), and the position of the throwing direction adjustment lever 33 is adjusted by loosening a part of the throwing direction adjusting lever 33 and rotating right and left in nine steps. The pitch angle can be changed. This allows
From elementary school to professional baseball players, it can be changed according to their height. In addition, it can be used separately for a higher ball and a lower ball. The pitch direction adjusting lever 3
The position of 3 is shown in FIG. 14 and can be easily adjusted from outside the fuselage.

In FIG. 6, protrusions 38 are provided inside the ball holding portion 2 as shown. Since the toss arm 1 of the present invention makes a circular motion around the drive shaft (the pivot shaft 3), the state changes from the conventional shot put state to the snap throw state. Therefore, at the position where the pitching operation ends, the ball a
Therefore, if the ball a is received over the entire circumference of the arc of the ball holding unit 2, it is difficult to determine the direction. In the present invention, in order to improve this point, the projections 38 are placed at the same positions as the two fingers, as in the case of snap throwing with the fingertip of a human.
It is located. The number of the projections 38 is not limited.

Next, a switching drive mechanism of the ball stopper 19 will be described with reference to FIGS. As aforementioned,
The rotation contact body 1 at the lower end of the rotating power take-out arm 15 is attached to the cam projection 4a and the cam flat portion 4b formed by the spring drive arm 4.
7 is in contact. The locking shaft 25 of the above-described throwing force urging spring 5 is fixed to the cam flat portion 4b of the spring drive arm 4, so that the first ball becomes an empty throw. . The cam projection 4a of the spring drive arm 4
The rotation power take-out arm 15 is rotated by the cam and the cam flat portion 4b, and the rotation power of the power take-out arm 15 is transmitted to the ball holding rail 8 by the rotation shaft 16 penetrating the center support plate A.
a.8b. The rotating power take-out arm 15 is urged by an urging spring 18 so that the rotating contact body 17 always contacts the cam surface of the spring drive arm 4. The above-mentioned rotating shaft 16 is connected to the ball holding rail 8a.
The switching protrusion arm 24 is fixedly provided at a portion protruding below 8b. The switching projection 2 is provided on the upper end of the switching projection arm 24.
3 are connected via a ball joint.

As shown in FIGS. 12 and 13, the switching projection 23 is configured to alternately push the left and right concave portions of the switching cam 22. The switching projection 23 is urged over the fulcrum by upper and lower fulcrum overcoming springs 20 and 21, and is constantly urged to be located at one side of the pivot shaft 39 of the ball stopper 19. Then, one of the spring drive arms 4
With the rotation, the switching projection 23 is moved to the top 22 a of the switching cam 22.
Is retracted to a position exceeding the fulcrum. At that position, the switching protrusion 23 receives a force for rotating the switching protrusion 23 on the side opposite to the fulcrum by the fulcrum over biasing springs 20 and 21. Thereby, the switching protrusion 2
3 enters the concave portions 22b and 22c of the left and right reverse switching cams 22 and pushes the corresponding portions, whereby the pivot shaft 39
Is rotated, the ball stopper 19 formed integrally with the pivot shaft 39 is switched to the opposite side of the ball holding rails 8a and 8b, and only one of the balls a on the opened side is
It falls into the guide gutter 44 and fits into the ball holding part 2. 8 and 9, the ball holding rails 8a and 8a
The ball stopper 19 is shown in a state where the lower end of b is viewed from above. 10 and 11, when viewed from below the lower ends of the ball holding rails 8a and 8b, the portions of the switching projection 23, the switching cam 22, and the biasing springs 20 and 21 beyond the fulcrum are illustrated.

[0025]

As described above, the present invention has the following advantages. The ball holding portion 2 at the tip of the toss arm 1 rotatably supported as described in claim 1,
The ball is held and the ball a
In the toss batting pitching device, the pitch of the ball a by the toss arm 1 is set to 1 every 3 to 4 seconds.
Hitting once, returning the bat to its original position, and immediately moving on to the next batting action,
You can practice toss batting at the same timing as toss batting with a normal assistant.

The ball is held by the ball holding portion 2 at the tip of the toss arm 1 rotatably supported,
In a toss batting pitching device for tossing a ball a by rotating the toss arm 1, the toss arm 1 is pivotally supported on a pivot shaft 3, and the toss arm 1 around the pivot shaft 3 is provided.
And the toss arm 1 is interposed between the spring drive arm 4 pivotally supported on the same axis of the pivot shaft 3 and the toss arm 1. Therefore, unlike the conventional art, the toss arm does not perform the elliptical motion, but has an arc motion centered on the drive shaft (the pivot shaft 3), so that the snap throw can be performed, and the small power of the geared motor 7 can be used. Thus, the ball a having the same energy as the conventional one can be thrown.

Since the toss arm 1 is made of a spring steel plate as described in claim 3, the toss arm 1 can be bent to throw a ball, and a snap-throw state can be created. It became possible to throw a strong ball similar to the pitch thrown by humans.

As described in claim 4, the ball holding portion 2 is provided at the tip of the toss arm 1, and the projection 38 is provided inside the ball holding portion 2 in contact with the outer periphery of the ball a along the pitching direction. In the case of the snap throw, the inconvenience that the throwing direction of the generated ball is not stable could be solved by creating the same state as the state of engagement with two fingers.

According to a fifth aspect of the present invention, the toss arm 1 is provided with a spring locking plate 6 for locking the pitching force biasing spring 5.
The toss arm 1 is bent without the toss arm 1 being bent by the tossing force urging spring 5, and the force of the tossing force urging spring 5 can be sufficiently applied to the toss arm 1 by the spring locking plate 6. It is.

Since the spring locking plate 6 also serves as a stopper plate for stopping the rotation of the toss arm 1 within the rotatable angle of the toss arm 1, the rotation of the toss arm 1 is actually performed. Although the movement is stopped by the upper rotation stopper 10 and the lower rotation stopper 11, the spring locking plate 6 is moved to the upper rotation stopper 10 and the lower rotation stopper 1
When the toss arm 1 is stopped by impact, the toss arm 1 is able to tolerate an impact impact on the lower rotation stopper 11 and the upper rotation stopper 10 while being bent by the spring plate.

Since the spring drive arm 4 rotates by directly transmitting the rotation after deceleration by the geared motor 7, the spring drive arm 4 rotates from the geared motor 7 to the drive shaft (the pivot shaft 3) as in the prior art. In the meantime, it was not necessary to hang a chain, and the cost was reduced and the weight was reduced.

According to an eighth aspect of the present invention, a mechanism for simultaneously switching the driving of the ball stoppers 19 for sequentially supplying the balls held on the ball holding rails 8 to the ball holding unit 2 by the rotational force of the geared motor 7 is provided. Without using a solenoid or another motor to drive the ball stopper 19, both can be driven by a single geared motor 7, thereby reducing cost and weight. .

According to the ninth aspect of the present invention, the pitching angle of the toss ball can be changed by changing the rotatable range of the toss arm 1 in the toss batting pitching apparatus. It was possible to use it from elementary school students to professional baseball players, and toss batting was possible from high to low balls.

According to the tenth aspect, the toss arm 1, the upper rotation stopper 10, and the lower rotation stopper 11 are simultaneously rotated about the pivot shaft 3, so that the pitch angle of the toss ball can be adjusted in a plurality of steps. By providing a pitch direction adjusting lever 33 outside the decorative cover 32 and integrally rotating the positions of the upper rotation stopper 10 and the lower rotation stopper 11, the pitch height can be easily changed. It has become.

According to the eleventh aspect of the present invention, in the toss batting pitcher, one of the four lower corners of the frame 12 is placed on one side.
A pair of caster wheels 13 is mounted, and the other is
4 and the frame 12 is tilted, so that the entire device is supported by the caster wheel 13 and can be moved by human power. Therefore, the device of the present invention can only be tilted by half in the direction of the caster wheel 13 to reduce the weight. In a light state, the traveling movement by the caster wheel 13 became possible.

According to a twelfth aspect of the present invention, the pitching interval is set to once every 3 to 4 seconds, and the main switch S is provided on the body side of the toss batting pitcher. After that, since the first ball is configured so that the pitching operation is performed in a state where the ball is not sent to the ball holding unit 2 of the toss arm 1, the main switch S is first pressed, and then the ball is moved to the hit position. In the meantime, the ball a coming out of the throwing opening 31 is no longer injured.

[0038] Since the present invention is configured as in claim 13, similarly,
This eliminates the need for the batter B to move across the front of the pitching opening 31 during the first ball.
