JPH09290036A - Ball position judging device for ball game - Google Patents

Abstract

PROBLEM TO BE SOLVED: To accurately confirm the locus of a bowling ball on a lane by installing a pressure sensor at a proper position on the bowling lane. SOLUTION: A pressure sensor 1 is installed on this side of targets 4 of a bowling lane 3 via a lane surface section in the lateral direction. The pressure sensor 1 is divided for individual cross grains of the lane 3 to judge on which plate a bowling ball has passed, or the pressure sensor 1 may be further divided to judge at which portion of which plate the bowling ball has passed. A piezoelectric sensor utilizing piezoelectric elements or a distortion resistance type pressure sensor utilizing distortion resistance elements can be considered for the pressure sensor 1, however it is not necessarily specified. The installation position of the pressure sensor 1 is not limited to the portion of the targets 4, and it may be installed near a guide section or at the intermediate position between the targets 4 and the guide. The passing position of the driven ball is detected, and the locus of the ball can be accurately known.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the position of a ball game ball which enables accurate position determination using a sensor without making an uncertain judgment by visually checking the trajectory of a bowling ball on a lane. The present invention relates to a determination device.

[0002]

2. Description of the Related Art Originally, a bowling lane has a target jet (a triangular target whose apex faces the pin direction, and a plurality of target jets are provided laterally along the lane) which serve as an index for pitching. The pitcher decides the best point according to his or her own ball line, standing position, aiming point, etc., and then throws with the goal as a goal. I am practicing.

[0003]

However, the ball passing position on the turret is roughly confirmed by eye confirmation, and it is impossible to know the exact passing position, and no matter how much pitching practice is accomplished, It was difficult to do the best practice.

The present invention has been made in view of the above points, and by accurately determining the whereabouts of a pitched ball, such as a ball passing position on a turret in a bowling lane, it is possible to achieve a pitching play and a pitching play in the best state at all times. An object of the present invention is to provide a position determination device for a ball game ball capable of practicing pitching.

[0005]

The position determining device for a ball game ball according to the present invention for attaining the above object is characterized in that a pressure sensor is laid on each of the target jets on the bowling lane.

[0006]

As described above, the position determination device for the ball game ball of the present invention detects the passing position of the bowling ball in the turret portion by the pressure sensor laid in the turret portion. Grasp
It is possible to pitch while confirming the ball line assuming each situation for each pitch, to perform the best practice, and to achieve the best play by producing the results of the practice at the time of production.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a partial plan view showing an embodiment of the present invention, and FIG. 2 is a partial sectional view.

In the drawings, reference numeral 1 is a pressure sensor, which is laid laterally in front of a turret 4 of a bowling lane 3 via a lane surface portion 2 to detect the passing position of a throwing ball and This is to make it possible to know the orbit accurately. Pressure sensor 1
May be divided for each plate of the lane 3 to determine which plate the bowling ball 5 has passed through, it is further subdivided into which part of the plate (for example, the fourth plate from the right). It may be possible to determine whether or not the plate has passed through the center portion). Although the pressure sensor 1 is laid under the lane surface portion 2 in this embodiment, the pressure sensor 1 may be formed into a tape shape and directly attached onto the lane surface portion 2.

The pressure sensor 1 may be a piezoelectric type piezoelectric sensor using a piezoelectric element or a strain resistance type pressure sensor using a strain resistance element, but it is not specified. Incidentally, the laying position of the pressure sensor 1 is not limited to the turret portion, but may be laid near the guide portion or at an intermediate position between the turret 4 and the guide. Further, the means for displaying the passing position of the bowling ball 5 is not specified, but since it is necessary to inform the exact position for each pitch, an electric light (lamp) is provided for each sensor laid on the lane to detect it. It is better to take a display means such as turning on the lamp of the place where

The above-described ball determination device for determining the position of the bowling ball on the lane is particularly effective during practice, and by recording data, it is possible to know the causal relationship between the variation of the pitch and the score result. There are many points to gain, and you can hope to practice with important exercises.

[0012]

As described above, according to the present invention,
It is possible to accurately determine the passing position of the bowling ball on the lane, and by notifying the pitcher of the passing position, it is possible to provide the situation in which the best practice of pitching can be provided, and the individual pitching technique Since it is very useful for improving and scoring, and further for improving the overall level, it can be said that this device is a very practical device, and has great effects for the ball player and related persons.
