Description

[Detailed Description of the Invention] This invention relates to a display device that mechanically automatically displays a baseball ball count using a disc pendulum.

Conventionally, baseball ball counts have only been indirectly displayed using permanent electric lights or manual displays, and there are almost no such facilities in grass field baseball fields.

Therefore, in grass baseball, there are often troubles due to unclear decisions by the umpire.

This proposal was made to eliminate this drawback, and uses a radio-controlled model device to directly connect the pitch umpire and the display via radio waves, and displays a count display similar to the count display on the indicator held by the pitch umpire. The ball count display on the receiver side is explained below with reference to the drawings.

B. Attach a dark green display board 2 and a back board 3 to the frame 1 to form a box shape, and display Strike S, Ball B, Out O, (hereinafter SBO) on the surface of the dark green display board 2.
Holes 4, 5, and 6 for displaying the count number are arranged in horizontal rows.

(b) Inside the box, on the front side of the dark green board 7 attached to the inside of the frame 1, disc pendulums 8, 9 are mounted by shafts 10, corresponding to the back sides of the display holes 4, 5, 6. It is supported and allowed to oscillate slightly laterally around its axis 10.

In order to make the disc pendulums 8 and 9 swing in one direction,
A stopper 11 made of a cushioning material such as rubber is attached to the base plate 7 on the upper right side of the disks of the disk pendulums 8 and 9.

C. The disc pendulums 8 and 9 have an upper mounting portion 12 that
The head 13 is made of metal or the like, and has a long hexagonal shape with narrow upper and lower sides, and a weight 14 is glued to the front surface of the head 13.

The width of the neck part 15 is particularly narrow, and there is a mounting hole in the lower center part through which the shaft 10 is passed, and a step 16 is attached below the neck part 15, and the part 17 for gluing the discs 8 and 9 protrudes in front, and the part 17 of the SBO Thin plastic discs 8, 9, color-coded according to the type of display, are glued on.

D. The channel 18 made of a metal plate has the recessed side at the front, below the channel 18, and the horizontal part 19.
has a partial cutout 20, and the SBO
Each channel 18 is provided in accordance with the number of disk pendulums 8, 9 that it handles, and is for rotating the disk pendulums 8, 9 in the order of display in relation to the disk pendulums 8, 9. Depending on the number of
The position and length are different.

E. On the front of the dark green board 7, there is a channel 18 support wheel 23 with retainers 22 on both sides.
are attached to the top, bottom, left and right at appropriate positions depending on the length of each channel 18 of the SBO, and are supported by passing between the upper and lower wheels 23 with the recessed side of the channel 18 in front.

The lower wheel 23 supports the horizontal portion 19 of the channel 18 other than the cutout 20.

When passing the channel 18 between the upper and lower wheels 23,
In order to associate with the disc pendulums 8 and 9, the heads 13 above the neck part 15 of the disc pendulums 8 and 9 are placed in the cutout part 20, and the right end 21 of the horizontal part below the channel 18 is connected to the disc pendulum 8. , 9 so that it hits slightly above the side of the neck 15.

The right end 21 of the horizontal portion below the channel 18 is bent to improve sliding when it hits the left side of the neck 15 of the disc pendulums 8, 9.

F. A servo motor 26 is attached to the left side surface of the dark green board 7, and a threaded shaft 28 at the top of an arm 27 attached to the servo motor shaft and a threaded shaft 25 at the left end of the channel 18 are connected to the servo motor 26. , are connected by a connecting plate 29.

This project has the above structure, so by operating the display dial of the indicator connected to the transmitter carried by the pitch umpire using radio control, the servo motor of the display on the receiver side also rotates, so the arm 27 Channel 18 connected to
Move left and right between the cars 23 and reach the right end 2 of the horizontal section 19.
1 hits the neck 15 of the disc pendulums 8 and 9, and the head 1
If you slide to 3, the disc pendulums 8 and 9 will lie down,
If it moves away from the head 13, it becomes vertical and displays similar to an indicator. channel 18
When the head 13 of the disk pendulums 8 and 9 moves to the leftmost position,
is inside the cutout 20 of the channel 18 and does not touch the channel 18, so the disc pendulums 8 and 9 are vertical, and the discs 8 and 9 are visible through the hole 4 of the display board 2, and the entire display is displayed. As the channel 18 moves to the right, the right end 21 of the horizontal part 19 hits the neck 15 of the rightmost disc pendulum 9, and as it continues to move, the left side of the long hexagon of the head 13 hits the neck 15 of the rightmost disc pendulum 9. The upper part of the disc pendulum 9 is connected to the axis 10.
The disc part 9 rotates to the right and descends, and conversely, the disc part 9 rotates to the left and goes up. When the head 13 is fully placed on the lower surface of the horizontal part 19 below the channel 18, the disc pendulum 9 turns sideways. The disk portion 9 then disappears from the hole 4 of the display panel 2, and the substrate 7 turns dark green and becomes non-display.

Note that as the channel 18 moves to the right, the disc pendulum 8 moves in the same way, and when the channel 18 moves to the farthest right, all the disc pendulums 8 and 9 lie horizontally and are not displayed.

Conversely, when the channel 18 moves to the left, the head 13 of the left disc pendulum 8 returns to the cutout part 20, and the side surface of the disc adhesive part 17 hits the steady rest 11, stopping the rotation and moving vertically. When the channel 18 is moved to the leftmost position, the disc pendulums 8 and 9 become vertical and the full display is achieved.

Therefore, the indicator numbers and the disk pendulum 8,
If you adjust the display order of 9, servo motor 2
By the precise movements of 6, the ball count can be displayed on the display as indicated by the umpire's decision.

The reason why the necks 15 of the disk pendulums 8 and 9 are narrow is to reduce the force that rotates the disk pendulums 8 and 9, and the head 13 of the disk pendulums is shaped like a long hexagon. The weight 14 is used to improve the balance between the disc parts 8 and 9 and the head 13 and to make the rotation lighter. The reason why the disk attachment portions 17 of the disk pendulums 8 and 9 protrude forward is to prevent the disk pendulums 8 and 9 from hitting the channel 18 when lying down.

Unlike conventional displays using electric lights, etc., it consumes less power during display, so it can be used for a long time with a small battery capacity, has low manufacturing costs, and has foldable and removable legs. This is a ball count display that can be installed anywhere on your phone and eliminates troubles with referees.
