Description

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

(Background Art) Conventionally, various structures have been provided for golf back practice devices used indoors or the like to return batted balls to all players. For example, Jikko 48-18
No. 282 and No. 52-6380, which use an inclined surface to return a cupped ball in the direction of 7 layers, have approximately 5
It is necessary to provide an angle of inclination of more than a, and as a result, the angle of inclination of the floor used for batting practice is also greater than that, which leads to larger practice equipment and makes the floor look unrealistic, lacking a sense of realism. The drawback was that it was not practical.

Ma'Its Special Publication No. 53-6578, Japanese Patent Publication No. 53-42
942, in which the ball is forcibly returned by a granger, etc., the ball is generally formed with a rear slope rC hocket on the floor, and is fully equipped with a kicking device to release the ball from this pocket toward the player. ,
Since the direction in which the ball is batted and the direction in which the ball is forced to be returned are on the same line, the player cannot hit the next ball until the ball is returned.

In addition, the depth of the pocket cannot be made too deep because the ball is ejected from the pocket in a strong mυ manner using a kicking device, and the ball that enters the pocket becomes '?'? There is a risk that it could easily fly out, and since the kick device is composed of an electromagnetic mechanism, there is a considerable amount of energy that can be used safely.
It had drawbacks such as being inconvenient to carry as it always required a wired connection and could not be made cordless.

(Object of the invention) The present invention has been proposed to solve the above-mentioned drawbacks.
The purpose of this is to use the feed lever to send the batted ball reliably into the throwing path, and to ensure that the ball is returned via a return path that is connected to this throwing path and is different from the direction in which it went from the putting field. This makes it possible to achieve a feel similar to an actual green or the feeling of a real game without having to slope the floor more than necessary, while also making the device more compact and allowing for continuous practice without hitting and returning balls colliding with each other. Our goal is to provide you with a butter practice device.

(Disclosure of invention) The present invention will be explained in detail below.

1 and 2 are a perspective view and a plan view of a putter practice device according to the present invention, and the putter practice device includes a long floor mat disposed between the player and the putter practice device as shown in FIG. FM can be installed. First, this putter practice device has a rectangular floor 17 that is continuous with the floor pine I-FM and has artificial grass etc. all planted on the surface, and surrounding it on three sides are side walls 2, a central housing 3, A ball return path housing 4 is erected, and between the floor l and the central housing 3 there is a ball return path housing 4 that descends from the side wall 2 toward the ball return path housing 4 at an angle of 5 degrees or more, and a ball return path housing 4 is provided. 4 is formed.

Here, a large number of narrow grooves are formed on the surface of the ball throwing path 50 along the rolling direction VC of the ball in order to reduce M friction resistance when the ball is transferred. In addition, a circular cup 6 is recessed in the center νζ of the floor 1 near the throwing path 5, and the cup 6 has a rotating function n'' for sending the ball cupped into the throwing path 5, as will be described later. A feed lever 7 is provided.

Furthermore, a display section 8L and a main switch 9 are provided on the front of the central housing 3, of which the display section 8 displays the number of balls that have been cupped in, and the number of balls that have not been cupped in and deviated to the left and right of the cup 6. can be displayed.

Incidentally, the 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 l. 'The figure also shows a knob for adjusting the 12I/i return distance, and 81!

Further, 42 is an adjustment groove that fully locks the knob 12, 44 is a ball return path of the ball return mechanism H, and 44 a is a circuit formed in the center of the ball return mechanism H to return the ball in a stable state. will be explained in detail later.

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. 3 and 4. In these figures, the sloped bottom plate 6 in the cup 6
The feed lever 7 disposed at the back of the cup 6 is rotatable upward by 90 degrees by means of a pivot 14. is provided, and a locking pin 16 is attached to the tip portion on the side of the central housing 3.

Furthermore, a switch spring 17 for driving a first morph 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 switch spring 17 that is in contact with the switch spring 17 is disposed below the first morph 21, which will be described later. -i- A fixed contact plate 1B is fixed on the substrate 19.

First, a motor support stand 2° is fixed inside the central housing 3 so that the board 19↓ is also positioned slightly upward, and the motor 21 on the upper surface VCHx of this motor support stand 20 is fixed.
is being addressed. The output shaft of this motor 21 is passed through the motor support stand 20.
A 4"-shaped eccentric plate 22 is fixedly installed to provide rotational OJ function. On the front and back sides of this eccentric plate 220, there is a pair of locking bosses 23 that face each other and protrude toward the motor support base 20, and a pair of suppression bosses 24 that are vertically installed in the direction of the board 19 in the vicinity of the eccentric shaft. is formed. Further, a switch spring 25 for motor 21@A movement is disposed on the substrate 19 so as to face the rotation path of the press boss 24, and is suppressed and driven by the rotating press boss 24. A defining contact 1Ji2 (i) with which the tip comes into contact is arranged below the eccentric plate 22.

Next, on the center line of the force feeding lever 7 on the side of the eccentric plate 22, a feeding plate 27 having a substantially L-shape in plan view is disposed. A locking notch 28 is formed at the end of the feed lever 711111 f7) of this feed plate 27, and the locking notch 28 locks with the locking pin 16 of the feed force lever 7, and the feed lever 711111f7) The other end of the plate 27 is bent at right angles in the direction of the eccentric plate 22 to completely form a locking piece 29. Further, the feed plate 27 is biased by a spring whose one end is fixed to the motor support base so as to constantly pull the feed lever 7 in the direction of the motor support base 20 . Here, the tip of the locking piece 29 locks into the locking boss 23 of the eccentric plate 22 that rotates eccentrically,
As the locking boss 23 rotates, the feed plate 27 is driven in the direction of the feed lever 7, and the locking piece 29 and the locking boss 23
The feed plate 27 returns to the spring 30 immediately after the lock is released. In FIG. 4, reference numeral 31 designates a battery storage case for portable use, and reference numeral 32 designates a step-down agegator connection terminal for use with commercial power.

Next, the ball return-like HMII will be described in detail with reference to FIGS. 5 to 7. As shown in FIGS. 5 and 6, a motor 33 of i2 is mounted on the board 19 near the end of the ball throwing path 5.
is fixed, and a substantially oval-shaped eccentric plate 34 similar to the eccentric plate 22 is attached to its output shaft, making it rotatable. A pair of locking bosses are vertically provided on the back surface of the eccentric plate 34, and as described later, they lock onto the striking piece 39 of the ball return lever 38 to drive the striking piece 39 or the ball return lever 38 against the spring 40. On the other hand, near the intersection of the throwing ball path 5 and the ball returning housing 4, a fixed contact plate 3G is disposed on the base plate 19, and slightly above the fixed contact plate 3G, there is provided a contact plate 3G that is connected to the ball B's own weight. A switch spring 37 for driving the motor 33 is arranged so as to swing downward and come into contact with the fixed contact plate 36, and one end of this switch spring 37 is fixed to the end of the substrate 19. In addition, a substantially frame-shaped ball return lever is provided on the upper blade of the fixed contact plate 36.
A striking piece 39 extending in the direction of the eccentric plate is integrally fixed to the end of the eccentric plate 341itll. Furthermore, the end of the ball return lever on the ball return housing 4 side is connected to a spring 4o.
The bent end of the adjustment lever is connected to the adjustment lever 41 through the bar, and the bent end of the adjustment bar is bored into the side wall of the ball return housing 4 as shown in FIG. It is locked in an adjustment groove 42 formed stepwise along the direction, and a knob 12 is attached to the tip.

That is, the ball return lever wing is always urged toward the exit of the ball return housing 4 by the spring 40. By changing the adjustment groove in which the adjustment lever 41 is locked, the fulcrum of the spring 40 can be changed. The impact force applied to the ball by the hitting piece 39 when the ball is returned, or in other words, the distance the ball returns can be made variable.

Next, FIG. 8 shows the entire ball return path 44 inside the ball return housing 4, and the center of the ball return path 44 is provided with a circuit 44a that matches the outer peripheral surface of the ball over its entire length. Furthermore, FIG. 9 shows the structure of a sensor that detects the ball straying to the left and right of the cup 6, and the switch spring 10
, ill/) A fixed contact plate 45 is provided on the lower blade, and is configured to output a p-count signal by contact with the switch springs 10 and 11 pressed by the ball.

When I explain the operation of Shito S, 7 “Layer-/
) When the ball enters the floor mat 1 ↓ and the floor mat into the cup 6, the ball rolls on the bottom plate 6a in the cup 6 shown in FIG.
Reach within 5. At the same time, the weight of the ball B closes the switch spring 17 and the fixed contact plate 18, and the first motor 21. t, i- and the eccentric plate 22 are driven. At the same time, a signal for counting the balls that have been cupped is emitted.

Now, if the position of the eccentric plate 22 in the state before the ball B is cupped in is as shown in FIG. It has been developed.

When the motor 21 rotates as described above with the cup-in, the eccentric plate 22 rotates in the clockwise direction, and the fixed contact plate 26 is closed by the force spring 25 and the fixed contact plate 26 as the suppression boss 24 moves. Ru. Therefore, the rotation of the motor 21 is continued thereafter.

As the eccentric plate 220 rotates, one of the locking bosses 23 comes into contact with and locks the locking piece 29 of the feed plate 27.
As shown in the figure 1-, as the eccentric plate 22 rotates, the feed plate 27 moves in the direction of one cup 6 while resisting the spring 30. At this time, the feed lever 7 with the locking pin 16 locked on the locking notch has the entire center of the pivot 14 and the ball receiver 15.
It rotates as if it were to spring up backwards, and finally rotates approximately 90 degrees as shown in Figure 11. Therefore, the ball B is sent out from the ball receiver 15 into the ball throwing path 5 and transferred toward the ball return mechanism H.

On the other hand, as shown in FIG. 11, the locking boss 23 and the locking piece 29
After a while after the eccentric plate 22 is disengaged, the linear part around the eccentric plate 22 comes close to the locking piece 29, so the locking piece 29, that is, the feed plate 27 loses the hook 9 and the spring 3
It is instantly pulled back by the restoring force of 0 and returns 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 suppression 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. At this time, if the switch spring 37 is inclined, the ball B moves following the movement of the striking piece 39 by the motor 33, so there is no gap between the ball B and the striking piece 39, and the striking This has the advantage of lowering the sound. The rotation speed of the feed lever 7 is slowed down to some extent by adjusting the rotation speed of the motor 21, and the return speed is controlled by a spring (9).
It is preferable to make the ball feeding faster than the ball feeding time by adjusting the above, so that even if the next ball enters the cup 6 after the feeding lever 7 starts to be driven, the ball will be fed by the feeding lever 7 which returns instantly. There is no need to worry about it being repelled and getting stuck inside the cup 6.

Next, ball B, which has been transferred down the sloped ball throwing path 5, is placed in the fifth ball.
As shown in the figure, it reaches the top of the switch spring 37, and its own weight forces the switch spring 37 to close the fixed contact plate 36' (i-).As a result, the second motor rotates, and the eccentric plate Rotate counterclockwise.

As the eccentric plate 34 rotates, the locking boss rises and the striking piece 3
9, and the striking piece 39 is driven upward in FIG. 5 while resisting the spring 40. At this time, a guide bottom surface 46 that descends and slopes toward the base end of the switch spring 37 is provided near the intersection of the ball throwing path 5 and the ball return path 44, as shown in FIGS. 6 and 12. B is striking piece 3
9 retreats, the centering plate 3 is moved back as shown in FIG.
Move to the side force of 4.

Thereafter, when the eccentric plate 34 further rotates from the state shown in FIG. The ball loses its grip, and due to the restoring force of the spring 40, it instantly moves in the direction of the return ball path 44, and the ball Be is struck and launched onto the return ball path 44, and is automatically sent to the player's feet via the circuit 44 a f. It returns the ball accurately and reliably.

In addition, according to this embodiment, since the restoring force of the spring is used as the ball return means, conventional granger etc.
Since the ball can be reliably returned with less electrical energy than an electromagnetic mechanism, it is possible to provide a portable product whose battery is electrolytically eroded, and a product that can be used anywhere. At the same time, the ball can be pushed out and returned by the ball return means consisting of a hitting piece, a spring, etc., and the impact noise can be reduced.

(Effects of the Invention) As described above, according to the present invention, a floor including a cup, a display section that displays the number of balls that have entered the cup, and a display section disposed between the cup and the display section. A feed lever 9 returns the ball in the direction of the ball throwing path provided, and detects that the ball is held on this feeding lever and operates the feeding lever to send the ball to the ball throwing path. The structure is such that the ball is returned via a feed lever that returns the ball to the throwing path, rather than by the inclination of the floor as in the past, so there is no need to tilt the floor more than necessary, allowing for miniaturization. Not only is this possible, but it also provides a sense of realism that is close to that of an actual green, and has the effect of allowing for practical practice.

Furthermore, since the direction of the putt and the direction of the forced return are different, there is no risk of the balls colliding with each other even if the ball is putted continuously, which has the advantage of allowing efficient practice in a short period of time.

In addition, compared to a case where the entire 114Il wall on the throwing path side of the cup is made to return the ball, the entire circumference of the cup can be made flush with a part of the floor, allowing the ball to touch the floor. This has the effect of preventing the ball from passing and rolling onto the throwing path without displaying a cup-in indication, thereby ensuring a cup-in indication.
