Description

[Detailed description of the invention] (Technical field) The present invention relates to a putting practice device.

(Background Art) Conventionally, various golf putt practice devices used indoors, etc., have been provided that automatically take out a ball that has entered a cup and have a structure for displaying a put-in.

For example, in the case of Utility Model Publications No. 48-18282 and No. 52-6380, which use an inclined surface to return the ball to the player, an inclination of approximately 5 degrees or more is used to return the ball smoothly. As a result, the angle of inclination of the floor used for putting practice becomes larger than that, which leads to the size of the practice device and the appearance of the floor to be unrealistic, resulting in a lack of realism and impractical. There were flaws. Furthermore, in these conventional examples, there is no indication that the ball has hit the ball, making it difficult to practice at a high level because it is unclear how likely the ball will hit. Furthermore, Mikoaki
For those having a display circuit like No. 51-36604, the above-mentioned Utility Model Publication Nos. 48-18282 and 52-6380
It had the disadvantage of becoming larger overall, as shown in the No.

Furthermore, if the ball that enters the cup is automatically taken out (or returned) by a motor, etc., and a switch installed at the bottom of the cup serves as both the cup-in display and the motor drive, the cup-in display will be free from motor noise and noise. This has the disadvantage that the display circuit tends to malfunction due to vibrations of the main body, resulting in lower reliability. Therefore, as a countermeasure, it is necessary to add a noise reduction circuit to the motor or to make the motor itself noiseless, which increases costs and
The drawback was that the overall structure became larger.

(Object of the Invention) The present invention has been proposed to solve the above-mentioned drawbacks, and its purpose is to miniaturize the main body by automatically taking out the cupped ball by a motor etc. This is a highly reliable cup-in that can be displayed reliably without being affected by body vibration, ball rebound, or even motor noise. An object of the present invention is to provide a putting practice device having a display circuit.

(Disclosure of invention) The present invention will be explained below with reference to the drawings.

FIG. 1 is a perspective view of a putt practice device according to the present invention. A central housing 3 and a ball return path housing 4 are provided upright, and between the floor 1 and the central housing 3, the housing is inclined downwardly from the side wall 2 toward the ball return path housing 4 at an angle of 5° or more. In addition, a ball throwing path 5 extending into the ball return path housing 4 is formed. Further, a circular cup 6 is recessed in the center of the floor 1 near the ball throwing path 5, and a rotatable sending lever for sending the cupped ball into the ball throwing path 5 is provided in the cup 6 as described later. 7 are arranged.

Furthermore, a display section 8 and a main switch 9 are provided on the front of the central housing 3, of which the display section 8 can display the number of balls that have been cupped in or the number of balls that have deviated to the left and right of the cup 6 without being cupped in. It's getting old. Incidentally, a ball that deviates to the left or right is detected by sensors consisting of switch springs 10, 11, etc. provided on the left and right sides of the back of the cup 6 on the floor 1. Further, in the figure, 12 indicates a knob for adjusting the return distance.

Next, the ball throwing mechanism G for sending the cupped ball into the ball throwing path 5 will be described in detail with reference to FIGS. 2 to 4. In these figures, cup 6
A feed lever 7 disposed at the back of the inner inclined bottom plate 6a is rotatable upward by approximately 90 degrees by a pivot 14, and a cup 6 is attached to the feed lever 7.
A ring-shaped ball receiver 15 is provided at the bottom of the housing, and a locking pin 16 is attached to the tip end on the side of the central housing 3. Further, a switch spring 17 for driving a first motor 21 (to be described later), which is supported at one end and can swing downward, is disposed in the through hole of the ball receiver 15, and a fixed contact plate that contacts the switch spring 17 is disposed below the switch spring 17. 18 is fixed on the substrate 19.

On the other hand, a motor support stand 20 is located inside the central housing 3 so as to be located slightly above the board 19.
is fixed, and a first motor 21 is attached to the upper surface of this motor support stand 20. The output shaft of this motor 21 passes through the motor support stand 20, and an approximately oval-shaped eccentric plate 22 is attached to the output shaft.
is fixed and can be rotated. On the front and back sides of the eccentric plate 22, there are a pair of locking bosses 23 facing each other and protruding toward the motor support base 20, and a pair of pressing bosses 24 vertically extending toward the board 19 in the vicinity of the eccentric shaft. It is formed. Also, press boss 2
A switch spring 25 for driving the motor 21, which is pressed and driven by the rotating press boss 24, is arranged on the base plate 19 so as to face the rotation path of the switch 4, and the tip of the switch spring 25 comes into contact with the switch spring 25. A fixed contact plate 26 is arranged below the eccentric plate 22.

Next, on the center line of the feed lever 7 on the side of the eccentric plate 22, a feed plate 27 having a substantially L-shape in plan view is disposed. A locking notch 28 is formed at the end of the feed plate 27 on the side of the feed lever 7, and the locking notch 28 locks with the locking pin 16 of the feed lever 7, and the other end of the feed plate 27 The portion is bent at right angles in the direction of the eccentric plate 22 to form a locking piece 29. Further, the feed plate 27 has one end connected to the motor support base 2.
A spring 30 fixed at zero is biased to constantly pull the feed lever 7 toward the motor support base 20. Further, as shown in FIG. 4, the feed plate 27 has a spring 30 on the side thereof.
When the motor is biased to be pulled in the direction of the motor support base 20, it is OFF, and when the feed plate 27 is driven in the direction of the feed lever 7 as described later, the locking piece 31 for the spring 30 of the feed plate 27 A switch 32 for a cut-in display circuit is provided, which is turned on when a switch piece 32a is pressed.

Here, the tip of the locking piece 29 can be locked to the locking boss 23 of the eccentric plate 22 that rotates eccentrically, and as the locking boss 23 rotates, the feed plate 27 is driven in the direction of the feed lever 7. At the moment when the locking piece 29 and the locking boss 23 are released, the spring 3
0 causes the feed plate 27 to return. In addition, in FIG. 3, 13 is a portable handhold part with a recess inside, and in FIG. 4, 33 is a battery storage case when using a battery for portable use, and 34 is a case when using a commercial power source. The step-down adapter connection terminals 40 each represent a motor block including a second motor 39, which will be described later.

Next, FIG. 5 is a schematic configuration diagram of a circuit for displaying the number of balls detected by the batted ball sensor on the display section 8. In the figure, 35 is a battery, _S1 is a switch spring 17, and a fixed contact. Board 18
A ball hitting sensor consisting of S ₁ ′ is a switch spring 25
A ball hitting sensor consisting of a fixed contact plate 26 and a fixed contact plate 26 are shown. A switch 32 is connected to a cut-in display circuit 36 that counts and displays the number of balls that have been cut in, and this switch 32 rotates the motor 21 and drives the feed lever 7 when the ball hit sensor S ₁ is turned on. Since it turns ON when the sensor is hit, it is in a relationship that is linked to the ball hitting sensor _S1 .

Further, in FIG. 5, 37 is a "left" display circuit that counts and displays the number of balls that have deflected to the left side of the cup 6, 38 is a "right" display circuit that also corresponds to balls that have deflected to the right side, and S ₂ is a batted ball sensor that includes a switch spring 10, and S ₃ is a batted ball sensor that includes a switch spring 11.
Although not shown in FIGS. 1 to 4, the ball hitting sensor 39 is a second sensor for hitting the ball B that has rolled from the ball throwing path 5 into the ball return path housing 4 and returning the ball to the player. The motor _S4 is a sensor for detecting the ball B.

To explain the operation, when a ball putt by a player passes through the floor 1 and enters the cup 6, the ball rolls on the bottom plate 6a in the cup 6 shown in FIG. 3 and reaches the ball receiver 15. . At the same time, the weight of the ball B closes the switch spring 17 and the fixed contact plate 18, which turns on the ball hitting sensor _S1 and drives the first motor 21 and the eccentric plate 22.

If the position of the eccentric plate 22 before the ball B is cupped in is as shown in FIG. 4, then one of the pressing bosses 24 is pressing the switch spring 25, and the fixed contact plate 26 is open. Further, the switch 32 for the cut-in display circuit is also in the OFF state. Then, when the motor 21 rotates as described above with the coupling, the eccentric plate 22 rotates clockwise, and the movement of the press boss 24 causes the switch spring 25 and the fixed contact plate 26 to rotate.
is closed. In other words, the batted ball sensor S ₁ ′ is turned ON. Therefore, the rotation of the motor 21 is continued thereafter.

As the eccentric plate 22 rotates, one of the locking bosses 23 eventually contacts and locks the locking piece 29 of the feed plate 27, and thereafter, as the eccentric plate 22 rotates, the feed plate 27 moves toward the cup 6 while resisting the spring 30. At this time, the feed lever 7 with the locking pin 16 locked in the locking notch 28
The ball receiver 15 pivots rearward about the pivot 14, and finally rotates approximately 90 degrees as shown in the imaginary line in FIG. 3 and in FIG. Therefore, the ball B is sent out from the ball receiver 15 into the ball throwing path 5 and rolls toward the ball returning path housing 4.

Also, at this time, since the feed plate 27 moves in the direction of the cup 6, the locking piece 31 of the feed plate 27 engages the switch 32 for the cup-in display circuit as shown in FIG.
Press the switch piece 32a to turn the switch 32.
The switch is turned on, and the cut-in display circuit 36 displays, for example, 0→1.

On the other hand, as shown in FIG. 7, after a while after the locking boss 23 and the locking piece 29 are disengaged, the linear part around the eccentric plate 22 comes close to the locking piece 29, so the locking The stopper 29, that is, the feed plate 27 loses its grip and is instantly pulled back by the restoring force of the spring 30, returning to the original position shown in FIG. 4, and the feed lever 7 also returns to the inside of the cup 6. . At the same time, the rotating pressing boss 24 presses the switch spring 25 and separates it from the fixed contact plate 26, so the motor 21 stops and the feeding operation of the ball B is completed, while the switch 32 for the cut-in display circuit is also fed. When the plate 27 returns, it returns to the OFF state.

In this embodiment, the ball throwing mechanism G using the motor 21 has been described, but it is also possible to use a solenoid or the like instead of the motor.

(Effects of the Invention) As described above, according to the present invention, there is provided a floor including a cup, a feed lever disposed inside the cup and rotatable toward the outside of the cup, and a ball attached to the feed lever. a ball throwing mechanism that detects with a ball hitting sensor that the ball is held and rotates the feed lever to send the ball to a ball throwing path provided outside the cup; and a cut-in display circuit that displays the number of balls that have been caught. , and a switch for displaying a push-in that closes in response to the push-in of the ball, and this switch for displaying the switch is linked to the ball hitting sensor, so instead of being driven by the inclination of the floor as in the past, it is driven by a motor, etc. By automatically sending the ball that has been cut into the throwing path, it is possible to downsize the ball without having to slope the floor more than necessary, and it also provides a realistic feeling close to the actual green, making it easier to practice. It has the effect of

In addition, the cut-in display circuit does not malfunction due to the noise of the motor that sends out the cup-in ball, the ball bouncing on the floor, or the ball bouncing off the central housing, resulting in highly reliable display. It has effects such as being able to provide a circuit.
