  Hereinafter, the best mode for realizing the toss batting device of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 9, the toss batting device according to the present embodiment includes a ball accommodating portion 1 that accommodates a large number of balls, a protective net 2 that protects the main body from hitting balls, and a wheel 3 that ensures ease of movement. And a motor 4 (drive unit) for supplying power to the entire apparatus, a supply device (supply means 5) for transporting the ball of the storage unit to a predetermined position, and a pitching device for throwing out the ball (inside the main body) The pitching means 6) and the swinging means 7 and 8 for swinging the ball of the housing portion are provided.

[The housing portion will be described. ]
The accommodating portion 1 is disposed on the upper side of the main body, and includes a side wall 9 that surrounds the four sides and a bottom plate 10 that is inclined inward, and has a volume capable of accommodating 100 to 200 hard baseball balls. The bottom plate has a base 11 hinged to the side wall 9 of the right side wall, and has a downward slope inward from the base 11, and the tip of the downward slope is bent downward. A ball lane 12 having a width through which the ball rolls is disposed at the end of the bent bottom plate 10.
Two rails 13 pass in the front-rear direction at the bottom of the ball lane 12, and the base of the rail 13 is hinged to the side wall 9, and the tip of the rail 13 is inclined downward toward the ball drop opening 15. .

The ball rolling on the rail 13 hits the impact plate 16 projecting on the opposite side of the drop port and falls, but the contact portion of the ball on the impact plate 16 is inclined downward.
Due to the formation of this inclination, the ball that hits the collision plate 16 is prevented from rebounding upward and falls to the drop port 15.
Because of this configuration, the balls in the housing portion 1 roll in the direction of the ball lane 12 along the inclination of the bottom plate 10, and when the balls are placed on the rails 13, they roll onto the drop opening 15. . The ball that has fallen into the drop opening 15 rolls on the bowl 17 in the stopper direction.

A swinging head 18 described later is connected to the lower side of the central portion of the two rails 13.
The oscillating head 18 has a function of lifting the tip portion of the rail 13. However, when the tip portion of the rail 13 is raised, a gap is generated between the rail tip and the main body, and there is a possibility that a ball enters the gap.
For this reason, in this embodiment, in order to prevent the ball from entering, a hanging plate 19 is disposed below the rail tip so as to block the ball from entering the gap even when the rail 13 tip rises. ing.

[The drive unit will be described. ]
The drive unit uses an electric motor 4 that uses a general household power supply as a power supply source. The motor 4 may be configured to be driven by the power of a portable generator or an internal combustion engine in addition to using a battery as a power supply source. And about the rotation speed of a motor, a torque, etc., it sets suitably according to the kind etc. of the ball to be used.

A drive shaft 20 protrudes from the motor 4 in the right horizontal direction, and a drive sprocket 21 is connected to the drive shaft 20. A chain 22 is looped over the drive sprocket 21 and connected to the ball supply side sprocket 23.
A drive head 24 protrudes from one end side (right side) of the drive shaft 20, and this drive head 24 is composed of a handle 25 protruding from the drive shaft 20 and rubber front and rear heads 24a, 24b at the tip thereof. The overall shape is a hammer shape (see FIG. 10).
The drive head 24 presses a driven head 26 described later to transmit power to the striking side sprocket 28.

[The pitching means will be described. ]
The pitching means 6 is driven by a driven sprocket 29 that receives power from the drive head 24 and rotates integrally with the driven head 26, a striking side sprocket 28 that is connected to the driven sprocket 29 by a chain 30, and a rotating shaft of the striking sprocket 28. A crank 32 connected to the left end of 31; a striking spring 33 connected to the crank 32; a flange 34 provided on the other end side (right end) of the striking spring 33; a striking arm 35 fixed to the flange 34; have.

[About driven sprocket]
The driven sprocket 29 is on the extended line of the drive shaft 20 of the motor 4, but is fixed to a separate and independent rotary shaft 36, and a hammer-like driven head 26 projects from one end of the rotary shaft 36.
The rotary shaft 36 may be externally fitted to the outer periphery of the drive shaft 20 via a bearing or the like so as to be separated from the drive shaft 20 by power and rotated independently.
Similar to the drive head 24, the driven head 26 is composed of a handle 27 protruding from the rotary shaft 36 and rubber front and rear heads 26a, 26b at the tip thereof, and the entire shape is a hammer shape.

[Battery sprocket]
The striking side sprocket 28 includes a horizontal rotating shaft 31 and is connected to a driven side sprocket 29 by a chain 30.
The crank 32 is fixed to the left end of the rotating shaft 31 of the striking side sprocket 28 and rotates in the front-rear direction. A pin 37 protrudes perpendicularly from the tip of the crank.
The striking spring is a coiled spring, the tip of which is attached to a connecting member 38 loosely fitted to the pin 37 of the crank 32, and the rear end is connected to the length adjusting handle 39.
The length adjusting handle 39 has a handle shaft 40 inserted through the horizontal member 41 and protrudes obliquely upward, and a striking spring 33 is connected to the tip of the length adjusting handle 39. By operating this length adjustment handle 39, it is possible to adjust the tension of the spring, thereby adjusting the speed of the hit ball.
The left and right attachment portions 42 between the horizontal member 41 and the frame are attached so that the horizontal member 41 is pivotable in the front-rear direction, and the impact of the spring 33 is applied to the attachment portion 42 between the horizontal member 41 and the frame. It absorbs by turning.

[About the striking arm]
The flange 34 is attached to the right end of the rotating shaft 31 of the striking side sprocket 28 and rotates in the front-rear direction.
The base of the hitting arm 35 is bolted to the flange 34, receives power through the flange 34, rotates forward and backward, and hits the ball. A rubber hitting head 35a is disposed at the hitting point of the ball at the tip of the hitting arm.
A pocket 43 in which a ball is set is arranged on the rotation trajectory of the striking head 35a at the lower right of the apparatus main body. The ball rolled into the pocket 43 is hit by the head 35a and a toss ball is thrown. The inclination angle of the pocket 43 can be adjusted, and the toss height can be set as appropriate.

  The driving head 24 and the driven head 26 are on the same rotation locus, and the front head 24a pushes the rear head 26b of the driven head 26 by the rotation of the driving head 24, and the elastic force of the spring 33 when it exceeds a certain rotation angle. The driven head and the driven sprocket 29 rapidly rotate, and the front head 26a of the driven head 26 collides with the rear head 24b of the drive head 24. In this collision, since the heads are made of rubber, the impact is reduced.

  With the above-described configuration, the pitching means 6 is rotated to a certain rotation angle by the power of the motor 4 to accumulate energy in the spring 33, and when the integral rotation angle is exceeded, the accumulation force of the spring 33 is released by releasing. The structure is such that the arm 35 is rapidly rotated to strike the ball.

[Next, the swinging means will be described. ]
The swinging means 7 and 8 of this embodiment are realized through a swing arm 44 that swings the bottom plate 10 and a swing rod 45 that swings the guide rail 13 (see FIG. 8).
First, the swinging means of the bottom plate 10 will be described.
A swing arm 44 projects from the outer periphery of one end of the crank 32 in the rotational direction. When the crank 32 rotates, the swing arm 44 repeatedly protrudes and descends to raise and lower the bottom plate.
That is, when the crank 32 is rotated by receiving the drive of the motor 4, the striking spring 33 is extended and the swing arm 44 is rotated and gradually protrudes upward.
When the swing arm 44 is protruded, the roller 46 at the tip of the swing arm 44 comes into contact with the bottom plate 10, and the bottom plate 10 is lifted by several cm while the roller 46 rotates.
Here, since the bottom plate 10 is hinged to the side wall of the base portion 11, the lower end portion of the bottom plate 10 is lifted with the hinge portion as a base point.
Even if a large number of balls are accommodated in the accommodating portion 1, power exceeding the gravity of the balls is transmitted from the drive motor to the swing arm 44.

[Next, the guide rail swinging means will be described. ]
The ball supply side sprocket 23 is connected by a chain 22 and rotates together with the drive sprocket 21.
The rotation axis 47 of the ball supply side sprocket 23 extends horizontally in the left-right direction, and a rotating disk 48 is connected to the left end thereof. A pin 49 projects from one end of the rotating disk 48. The base ends of these are loosely fitted and connected.
When the turntable 48 rotates, the pin 49 moves up and down together with the turntable 48, and the base end of the rod 50 and the rod 50 main body move up and down with the up and down movement.
The tip of the rod 50 extends upward and is transmitted to the rocking rod 45 via a link 52 disposed on the slide rail 51 so as to be movable up and down (see FIG. 5).

This vertical movement is transmitted to the oscillating head 18 via the slide rail 51, and the guide rail 13 moves up and down as the oscillating head 18 moves up and down.
When the guide rail 13 moves up and down, even when balls are in contact with each other and a ball is clogged, the ball is smoothly flowed out.
In particular, hard baseballs have a leather outer skin that easily absorbs moisture, which causes problems such as dirt, sand, etc. adhering, high frictional resistance, and ball clogging. The presence of the swing device eliminates the possibility of ball clogging.

  The bottom plate 10 swings by receiving a drive from the rotating shaft 31 of the striking side sprocket 28, whereas the guide rail 13 swings by receiving a drive from the rotating shaft 47 of the ball supply side sprocket 23. . These swings are made at a pitch of one per rotation of the striking arm, and the timing of these swings changes the position of the swing arm 44 or the position of the pin 49 on the rotary disk 48, etc. Can be set as appropriate.

[Next, supply means for feeding the ball to the hitting pocket will be described. ]
As shown in FIG. 9, the ball supply means is a hook 17 that supplies the ball of the housing portion 1 to the hitting pocket 43, and a ball stop and hitting pocket at the lowermost end of the hook 17 that is disposed at the tip of the hook. 43 is provided with a final stopper 53 for controlling the supply to 43 and a subsequent stopper 54 for controlling the progress of the ball immediately before the lowest end.
The hook 17 is a passage made of a metal plate, a resin plate, or the like. However, the hook 17 only needs to be configured so that the ball rolls under its own weight, and can be formed of a rail.

[About the final stopper]
The final stopper 53 includes a tilting shaft 55 that is inserted in the front-rear direction of the main body perpendicular to the moving direction of the ball, and a concave plate 56 that includes a vertical plate that has a base fixed to the tilting shaft 55 and protrudes upward. It has.
The concave plate 56 includes an arcuate depression 57 that accommodates the ball between the front piece 56a and the rear piece 56b, and is disposed directly below the center of the rod 17 along the traveling direction of the ball. A front piece 56a and a rear piece 56b of the concave plate 56 are projected from the bottom of the flange 17 and moved back and forth, thereby providing a function of controlling the progress and stop of the ball accommodated in the depressed portion 57.
That is, if the concave plate 56 is tilted forward by operating the tilting shaft 55 in a state where the ball is set in the depressed portion 57, the front piece 56a is hidden under the heel and the stop state of the ball is released. At the same time, the rear piece 56b has a function of pushing the ball forward.
The pushed ball rolls down the cage 17 and is set in the hitting pocket 43.
When the concave plate 56 is tilted backward by the tilting of the tilting shaft 55, the rear piece 56 b is hidden under the flange 17, and at the same time, the front piece 56 a appears from below the flange 17, so that the ball can be received in the depressed portion 57. The

  If the ball is supplied by tilting the concave plate 56, the rear piece 56b of the depressed portion 57 may interfere with the subsequent ball. That is, when the concave plate 56 is tilted forward, the rear piece 56b appears from below the flange 17 and may come into contact with the subsequent ball, thereby hindering the forward tilt of the concave plate 56. In addition, when the concave plate 56 tilts backward, the subsequent ball may press the rear piece 56b, and the backward tilt of the concave plate 56 may be hindered.

[Subsequent stopper]
Therefore, in the present invention, a trailing stopper 54 for smoothly tilting the concave plate 56 is provided.
Hereinafter, the subsequent stopper will be described.
The trailing stopper 54 is connected to the tilt shaft 55 inserted in the front-rear direction of the main body, the left and right arms 58a and 58b at the tip of the tilt shaft 55, the coil spring 59 connected to the right end of the arm 58b, and the left side of the arm 58a. And a link mechanism 61 that operates via the chain 60.
[Tilt axis]
A locking piece 62 is projected in the horizontal direction at the base of the tilting shaft 55, and the pin 64 of the rotating disk 63 comes into contact with the locking piece 62 to rotate the tilting shaft 55. Yes.
A rotating disk 63 is connected to the rotating shaft 47 of the ball supply sprocket 23, and a pin 64 protrudes from one end of the rotating disk 63. The pin 64 rotates as the rotating shaft 47 rotates. The locking piece 62 is tilted to a certain angle. When the pin 64 lifts the locking piece 62 to a certain angle, the tilting shaft 55 tilts accordingly, and after reaching the certain angle, the pin 64 is unlocked, and the tilting shaft 55 returns to its original position. Return.

[About the arm]
At the tip of the tilting shaft 55, arms 58 a and 58 b protrude from the left and right perpendicular to the axis. A coil spring 59 is connected upward to the tip of the right arm 58b and pulled upward. A chain 60 (string) is connected to the tip of the left arm 58a so as to pull the link mechanism 61 downward.
These arms 58a and 58b have a relationship in which when the tip end of one arm rises from the tilting shaft 55, the tip end of the other arm descends, and when the tip end of one arm descends, the tip end of the other arm rises.

[Link mechanism]
The link mechanism 61 includes a link 65 arranged in a horizontal direction, a support 66 that rotatably supports the central portion of the link 65, a coil spring 67 that is attached to the support 66 and pulls the base of the link 65 upward, A protrusion 68 is provided at the tip of the link 65 to press the top of the ball.
According to this link mechanism 61, when the tilt shaft 55 tilts in the direction in which the chain 60 is slackened, the coil spring 67 pulls the link 65 base portion upward, the link 65 rotates about the shaft support portion, and the projection 68 at the tip of the link 65. Descends and presses the ball. This stops the subsequent ball.
On the other hand, when the tilting shaft 55 tilts in the direction of pulling the chain 60 downward, the link 65 rotates about the shaft support portion against the spring 67, and the projection 68 at the tip of the link 65 rises away from the ball, The stop state of the following ball is released.

As described above, the tilting shaft 55 has a function of transmitting power to the two types of stoppers, that is, the tilting of the concave plate 56 and the vertical movement of the protrusion 68.
That is, when the tilting shaft 55 rotates to the right, the concave plate 56 tilts forward and the ball is fed out. At the same time, the arm 58a rises to loosen the chain 60, and the protrusion 68 at the tip of the link 65 stops the rolling of the subsequent ball.
Thereby, the rear piece 56b of the concave plate 56 is prevented from interfering with the succeeding ball, and can be sent out to the hitting pocket.
Subsequently, when the pin 64 is removed from the locking piece 62 at the base of the tilting shaft 55, the spring 59 pulls the tip of the arm 58b upward, and the tilting shaft 55 returns to its original position. As a result, the concave plate 56 tilts backward. Here, when the tilting shaft 55 returns to the original position, the succeeding ball is stopped by the protrusion 68, so that the rear piece 56b of the concave plate 56 returns smoothly without being pressed by the succeeding ball.
At the same time, the arm 58a is lowered to pull the chain 60 downward, the protrusion 68 at the tip of the link 65 is raised, and the stop state of the subsequent ball is released. Then, the succeeding ball rolls into the depressed portion 57 of the concave plate 56 and enters a standby state for the next ball supply.

Due to the above configuration, the striking side sprocket 28 is driven by the power of the motor 4 and rotated to a certain rotation angle to store energy in the spring 33. When the integrated rotation angle is exceeded, the stored energy of the spring 33 is exceeded. Can be released, and the ball can be launched by applying rapid rotation to the striking arm 35. On the other hand, the bottom plate 10 is swung by using the rotation of the crank 32 to smoothly convey the ball, and the ball supply side sprocket 23 is driven by the power of the motor to swing the guide rail 13.
Further, by utilizing the rotation of the ball supply side sprocket 23, the final stopper 53 and the subsequent stopper 54 are operated to supply the ball to the ball pocket 43 in synchronization with the striking arm 35.
Therefore, in the toss batting device of the present invention, the elastic body is driven to store energy and the tension is released by the power of only the rotation drive unit, the ball is supplied by the supply means, and the swinging means is further driven. can do.

[Next, the operation of this embodiment will be described with reference to FIGS. ]
When the device is switched on, the driving sprocket 21 and the driving head 24 are rotated by the power of the motor 4 (FIG. 10A).
In FIG. 10A, only the driving head 24 rotates, and the driven head 26, the crank 32, and the striking arm 35 are stopped.
As shown in FIG. 10B, when the front head 24 a hits the rear head 26 b of the driven head 26 by the rotation of the driving head 24, the driving head 24 gradually rotates while pushing the driven head 26.
At this time, the crank 32 and the striking arm 35 also rotate.

When the position shown in FIG. 10C is reached, the swing arm 44 protruding from the crank 32 protrudes upward and pushes up the bottom plate 10 of the housing portion. Even when a large number of balls are housed in the housing portion, the swinging means eliminates the clogging of the balls.
Here, the pin 37 pulls the spring 33 by the rotation of the crank 32, and the spring is extended to accumulate the tension.

In the position of FIG. 11 (d), the pin 37 of the crank 32 moves away from the pulling direction of the spring 33, so that the pulling force of the spring 33 is accumulated to the maximum.
When the pulling direction of the spring 33 coincides with or slightly exceeds the line connecting the rotation shaft 31 of the crank 32 and the pin 37, the stored force of the spring 33 is released. Then, the spring 33 pulls the crank 32 rapidly, and the striking arm 35 is swung down from above by this rapid rotation and strikes the ball in the striking pocket 43 (FIG. 11 (e)).
At this time, the driven arm 26 also rotates rapidly, and the front head 26a of the driven arm collides with the rear head 24b of the drive arm 24 due to the rotational inertia, but each head is made of rubber and absorbs this impact. .
Further, since the impact spring 33 rapidly shrinks, this impact is transmitted to the length adjustment handle 39. However, the left and right attachment portions 42 between the horizontal member 41, which is a fixed portion of the length adjustment handle 39, and the frame are The horizontal member 41 is attached so as to be rotatable in the front-rear direction, and the elastic impact of the spring 33 is absorbed by the attachment part 42 between the horizontal member 41 and the frame rotating.

On the other hand, the ball supply side sprocket 23 is rotating in parallel with the rotation of the striking side sprocket 28. At the left end of the ball supply side sprocket 23, the rod 50 and the swing head 18 are moved up and down by the rotating disk 48 to move the guide rail 13 up and down.
In addition, the pin 64 of the rotating disk 63 of the ball supply side sprocket 23 tilts the tilting shaft 55 and operates the concave plate 56 and the subsequent stopper 53 to supply the ball to the striking pocket 43 in time.

Although the embodiments have been described above, the specific configuration of the present invention is not limited to the above-described embodiments, and design changes and the like within a scope not departing from the gist of the invention are included in the present invention.
For example, although the toss batting device for a hard baseball has been described in the above embodiment, the type of the ball is not particularly limited.
Further, as the striking spring described in the embodiment, it is possible to use a rubber, a leaf spring or the like in addition to the coil spring.
