Embodiments of the present invention will be described below with reference to the drawings. The goal post 1 of the present invention has a dish cup 2 having an upper surface formed in a dish shape in order to catch a ball rolling on the ground surface, and a lower end fixed to the center of the goal cup 2 and erected. A post 3; a goal detecting means 4 for detecting that the ball has been caught in the goal cup 2; and a goal displaying means 5 for displaying that the ball has scored based on the detection result of the goal detecting means 4. Have been.

The goal cup 2 is formed of a material such as a synthetic resin or a metal and is formed as a flat circular base member 6 so that the lower surface can be stably mounted on the ground surface. The outermost peripheral edge 7 is formed thin so that it is easy to catch the game ball rolling on the ground surface,
An inclined surface 8 that gradually faces upward from the outer peripheral edge 7 toward the center is formed in an annular shape, and a ridge 9 having a diameter slightly smaller than the outer diameter is formed. The inside of the ridge 9 is the range of the cup-in of the ball. On the inner side of the ridge 9, an inclined surface 1 having a downward slope toward the center of the goal cup 2 so as to move the cupped ball toward the center of the goal cup 2.
0 is formed all around.

A post 3 made of a pipe material such as synthetic resin or metal is provided upright from the center of the goal cup 2 upward in the vertical direction. The lower end of the post 3 is fixed to a boss 11 formed at the center of the goal cup 2.

In a portion near the lower end of the post 3, goal detecting means 4 for detecting that the ball has been cupped in is provided.
Is installed. The goal detecting means 4 is composed of a movable switch member 12 configured to be actuated in contact with the ball that has been cupped in, and a fixed switch member 13 installed on the outer peripheral surface of the post 3. The movable switch member 12 swings by bringing the in-ball into the center portion by the inclined surface 10 of the goal cup 2 and comes into contact with the fixed switch member 13 to output a ball capture signal.

The movable switch member 12 comprises a cylindrical operating member 14 whose upper end is swingably supported by the post 3, and a switch terminal 15 attached to the inner peripheral surface of the operating member 14. The fixed switch member 13 is composed of a switch terminal 16 attached to the outer peripheral surface of the post 3. A signal line connected to each of the switch terminals 15 and 16 is connected to a control unit 17 described later through the hollow inside of the post 3. As shown in FIG. 3, the ball which has been cupped in comes into contact with the cylindrical operating member 14 to swing it, and the switch terminal 15 of the operating member 14 and the switch terminal 16 installed on the outer peripheral surface of the post 3 come into contact. By doing so, a ball capture detection signal is output through the signal line.

A cylindrical case 18 is formed in the middle of the post 3 so that the post 3 passes through a hole formed in the center.
The case 18 has a control unit 1 inside.
7, a goal determination circuit 20, a time determination circuit 21,
And a driver circuit 22 mounted and accommodated on the substrate 19.

As described above, the goal detecting means 4 emits a signal when the movable switch member 12 and the switch terminals 15 and 16 of the fixed switch member 13 come into contact with each other. Even when the member 12 comes into contact with the member 12, the momentum may go outside due to excessive momentum and may not be recognized as a goal. Or, the movable switch member 12 swings due to wind or the like, and both switch contacts 15, 1
6 may contact and output a signal. Further, when the player takes up the cupped-in ball, the movable switch member may swing and output as a detection signal.
A goal determination circuit 20 is provided to prevent the goal display means 5 from operating when the goal is not a legitimate goal.

The goal determination circuit 20 includes a goal detection means 4
Is detected to be maintained for a certain period of time to determine whether the goal is a legitimate goal. The goal determination circuit 20 detects whether or not the signal from the goal detection means 4 has been maintained for a certain period of time (for example, about 3 seconds). A goal signal is determined and a goal determination signal is output to the time determination circuit 21 at the subsequent stage. By the circuit 20, even if the ball passes through the cup or the switch terminal momentarily contacts due to the action of wind or the like and a very short-time signal is output, it is not determined that the ball is a goal and the goal is displayed. I try not to. When the goal determination circuit 20 removes the cupped ball from the cup, the switch terminals 15, 1
In order to prevent the switch terminals 15 and 16 from coming into contact with each other by the chattering of 6 and the swinging of the operating member after the ball is taken out, the goal detection means 4 is turned off for a certain period of time, for example, about 3 seconds. Is detected and the next ball cup-in is validated.

The time determination circuit 21 outputs a drive signal for a predetermined time for displaying the goal display means 5 for a predetermined time based on the goal determination signal output from the previous goal determination circuit 20. For example, as the driving signal, an HI signal of about 4 seconds is output to the driver circuit 22 at the subsequent stage so that the goal is displayed for 4 seconds after the transmission of the goal determination signal.
This drive signal is input to the driver circuit 22 and output as a current-amplified power signal suitable for each display means to operate each display means.

As the goal display means 5, for example, various kinds of display means 23 such as an acoustic display using a melody or a buzzer or an optical display using a xenon strobe or a rotating light can be selected. A plurality of display means can be used in combination. In the embodiment, a xenon strobe 24 is used as an optical display means, and the post 3
A melody sound generator 25 for producing an electronic melody sound is provided in a case 18 held in the middle of the post 3, and a speaker 25a is provided facing the outside of the case. These display means 24, 25
It operates for a predetermined time according to the power signal from the driver circuit 22 to allow many players to recognize that the ball has properly scored a goal. In the case of display using an electronic buzzer or a melody, any one of a plurality of melodies stored in the storage means can be selectively switched to a different melody from a goal post used in another hall by using a dip switch or the like. It is possible to display different melodies for each goal post, eliminating errors between holes.

A power supply for supplying power for driving the goal detecting means 4, the circuits 20, 21 and 22 of the control unit 17, and the goal displaying means 5 is provided by a primary battery or a secondary battery stored in the case 18. It is composed of a battery 26 such as a secondary battery, and can be used even in a place without power supply equipment. The goal detecting means 4 and the goal displaying means 5 which are arranged apart from the case 18 are wired using the hollow interior of the post 3. The control unit 17 is designed to save power and can be used for several months even with a small battery, but it is also possible to use a combination of a secondary battery and a solar battery.

As described above, according to the present invention, many players can recognize that a ball has reached a goal by voice, light, or the like. It can be fun. By installing the goal determination circuit, malfunction of the display means other than the regular goal can be prevented.
