Description

  The present invention relates to a golf practice net and a golf practice apparatus equipped with the same, and more particularly to a golf practice net used for a golf practice apparatus suitable for practicing approach shots indoors.

Various golf practice apparatuses for practicing chip shots around 5 to 20 yards around the green at actual approach intervals have been proposed.
When used indoors, from the viewpoint of noise suppression, it is desirable to reduce as much as possible the impact sound and vibration when hit with a hit ball.
From this point of view, a catch net with a large area for catching the hit ball and an approach practice net structure in which a single hit ball catching net with a smaller area than the catch net is suspended in front of the catch net when viewed from the batter side are proposed. (For example, Patent Document 1).

The hit ball receiving net is provided for the purpose of absorbing the impact of the hit ball by free deformability by suspending, catching the ball so as to wrap it, and dropping it downward.
In this type of so-called two-stage net configuration, the batter hits the ball with the target hitting ball receiving net as the target, and the ball that does not hit the hitting ball receiving net is received by the catch net that is held behind.

Utility Model Registration No. 3093732

The direction of rebound of the ball that hits the catch net varies in many ways. For example, the ball also flies in the horizontal direction perpendicular to the direction in which the ball receiving net hangs down. However, since the hit ball receiving net has a single piece structure as described above, there is almost no area for receiving a ball flying in the horizontal direction. For this reason, the bounced ball may easily pass through the area of the hit ball receiving net and jump out of the net area and fall.
Generally, a flexible mat that absorbs and receives the impact of the falling ball is placed under the catch net and the ball receiving net. However, a ball that flies outside the net area falls directly onto the floor, for example. Sound is generated.

In addition, if the hitting ball catching net is a single piece, the degree of freedom is too great, so that when the hit ball hits, it does not have enough room to wrap and wrap, and it only contributes to the catching net, directly to the catch net The number of hit sounds (impact sounds) increases.
In Patent Document 1, in order to eliminate such disadvantages of the single-sheet configuration, the peripheral edges on the four sides of the ball receiving net are sandwiched by a thin rubber plate to ensure the shape retention by gravity. It becomes a factor of the impact sound generation.

  The present invention has been made in view of such a current situation, and an object thereof is to provide a golf practice net that can highly accurately suppress noise when a hit ball is received and can suppress the jumping-out of a rebounding ball with high accuracy.

In order to achieve the above object, the golf practice net of the present invention is provided in front of the first net for receiving the hit ball and the first net as viewed from the batter side, and is supported by the upper end side and extends downward. and a second net, a second net, perforated and the front portion as a target to shed facing hitting the striking person, and a side portion extending in a first net side continuously to the front surface portion And a hook member for supporting the upper end of the second net so as to expand in the left-right direction along an elongated loop shape, and the second net is detachably attached to the frame supporting the first net by the hook member. Is provided .

  ADVANTAGE OF THE INVENTION According to this invention, the golf practice net | network which can suppress the improvement in noise reduction when receiving a hit ball and the jumping-out of a rebound ball can be provided with high precision.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a use state of the golf practice apparatus 1 according to the present embodiment. The golf practice device 1 includes a golf practice net 2, a ball cradle 3 that accommodates a ball that falls on the golf practice net 2, a frame 4 that supports the golf practice net 2 and the ball cradle 3, and one end. A return rail member 5 whose part is connected to the ball receiving base 3 and a ball supply unit 6 to which the other end of the return rail member 5 is connected are provided.
In FIG. 1, reference numeral 7 indicates a practice mat 7 as a shot position on which a ball (golf ball) 8 is placed.
The ball 8 hit from the practice mat 7 hits the golf practice net 2 and falls to the ball cradle 3, rolls on the inclined surface of the ball cradle 3, is guided to the right side when viewed from the batter, and moves on the return rail member 5. It is a circulation system that rolls and reaches the ball supply unit 6.
Here, a type corresponding to a right-handed batter is illustrated.

The golf practice apparatus 1 has a size that can be used between, for example, 6 tatami mats in a condominium or a detached room. Specifically, the height H1 from the floor surface of the golf practice net 2 is 180 cm, and the distance D from the shot position to the net is about 2.5 m. The maximum width W including the golf practice net 2 and the ball cradle 3 is about 80 cm. These dimensions are examples and are not limited to these.
As will be described later, the height of the golf practice net 2 can be arbitrarily adjusted so as to be lower in the range of about 60 cm with H1 as the upper limit, and the ball support 3 can be folded to the net side. That is, it can be made compact when not in use, and can occupy less space.

The golf practice net 2 is attached to a frame 4 via a plug-in type buckle 9, and a base net 10 as a first net supported at the upper and lower ends of the frame 4 and a base viewed from the batter side. It has a bag-shaped front net 11 as a second net that is provided in front of the net 10 and extends downward while being supported at the upper end side.
The batter hits the ball 8 aiming at the front net 11, but the ball 8 outside the front net 11 is received by the base net 10 having a large area reserved at the rear stage.
The front stage net 11 is suspended in a state where the lower end side hangs down, and when the hit ball hits, the entire front stage net 11 can swing like a swing.

Based on FIG. 2, the structure of the frame 4 is demonstrated. FIG. 2 shows a state where the front net 11 is removed.
The frame 4 has an upper frame 12 that supports the base net 10 and a lower frame 13 that supports the ball cradle 3. The upper frame 12 has two fixed columns 12a extending vertically and two movable columns 12b extending vertically. A cylindrical guide 12c is fixed to the upper end side of the fixed column 12a, and the movable column 12b is inserted through the guide 12c. A cylindrical slider 12d through which the fixed column 12a is inserted is fixed to the lower end side of the movable column 12b.

By operating a fixing screw (not shown) provided on at least one of the guide 12c and the slider 12d, the height H1 of the net can be adjusted.
A horizontal bar 12e extending so as to spread outward toward the batter side is provided on each of the upper ends of the two movable struts 12b, and a horizontal bar 12f is provided on the lower frame 13 correspondingly. Yes.
The front end portions 12e-1 and 12f-1 of the horizontal bars 12e and 12f are provided so as to be rotatable in the horizontal direction.
Support bars 12g and 12g extending horizontally and parallel to the batter side are fixed to the base portions of the horizontal bars 12e and 12e.

The lower frame 13 is configured to have a rectangular parallelepiped outline, and a support bar 13a that can be rotated in the horizontal direction is provided on the front side (batter side). The support bar 13a can be stored inside the lower frame 13 so as not to protrude when the ball support 3 is folded (see FIG. 25).
A cylindrical joint 14 into which a support rod 60 (see FIG. 25) of a ball cradle 3 described later is inserted is provided on the front upper horizontal bar 13b constituting the lower frame 13 so as to be rotatable in the vertical direction. Yes.
On the lower surface of the lower frame 13, casters 15 for facilitating movement are attached at four locations.

  In this embodiment, the frame 4 is configured using a plurality of metal pipe members and joints, but the fixed portion may be integrally formed with resin or the like as appropriate.

FIG. 3 is a view of the frame body 4 as viewed from above. The horizontal spread of the base net 10 can be adjusted by rotating the front ends 12e-1 and 12f-1 of the horizontal bars 12e and 12f of the upper frame 12, and as shown in FIG. It is also possible to fold the both sides inward by shifting the back side.
As shown in FIG. 4, the front net 11 has a smaller area than the base net 10, is located at the center of the base net 10, and its lower end is slightly higher than the upper surface of the ball cradle 3.
A shutter member 16 is provided at the front lower part of the ball receiving base 3 so as to be slidable in the left-right direction. The opening on the right side that is not covered by the shutter member 16 serves as a right-handed connection port 17R into which one end of the return rail member 5 is inserted. The return rail member 5 is set only by inserting the end portion into the connection port 17R and placing it.
As shown in FIG. 1, one end portion of the return rail member 5 can be further inserted into the net side while being placed on the connection port 17R, whereby the distance D from the shot position to the net can be adjusted to be shortened by about 50 cm. The same applies when connected to the connection port 17L.

In the case of left-handedness, as shown in FIG. 5, the shutter member 16 is slid to the right, and one end of the return rail member 5 is inserted into the connection port 17L and set.
The shutter member 16 is formed of a soft sheet material and is edged with a narrow metal plate in order to mitigate the impact sound when a ball that is warped downward without hitting the front net 11 is hit. The surface of the metal plate may be covered with a flexible member such as a sponge.
As the soft sheet material, for example, a small perforated sheet in which polyester fiber is coated with vinyl chloride can be employed.
By providing the shutter member 16, it is possible to prevent a sphere from entering the connection port that is not used in a configuration that can handle both right-handed and left-handed, and it is possible to eliminate poor appearance.

As shown in FIG. 6, the front net 11 has at least a front surface portion 11a facing the batter, and a side surface portion 11b extending continuously from the front surface portion 11a to the first net side (base net 10 side). Yes. In this embodiment, the side part 11b is formed in the bag shape continued on the base net 10 side. The front net 11 has a shape in which the internal space becomes narrower downward.
The front-stage net 11 has a hook member 18 that supports the upper end portion in an expanded state, and is detachably provided on a support bar 12g fixed to the upper frame 12 that supports the base net 10 by the hook member 18.

The hook member 18 includes an oval loop-shaped support portion 19 to which the upper end portion of the front net 11 is fixed, and a hook 20 provided integrally with the loop-shaped support portion 19.
The hook 20 has two hooking portions 20 a spaced from each other in the width direction of the front net 11, and is fixed to the loop-shaped support portion 19 with screws 21. By placing the hook 20a of the hook 20 on the tip of the support bar 12g in an unfixed state, the front net 11 can swing like a swing.
Two protrusions 12h are formed at the tip of the support bar 12g to prevent the hooking portion 20a from coming off and being displaced.

As shown in FIG. 7, the base net 10 has a front portion 10a facing the batter, and a side portion 10b extending so as to spread from both sides of the front portion 10a toward the batter side. The front net 11 has the same width as the front part 10a of the base net 10, and the base net 10 side is a back part 11c.
The ball 8 hit from the practice mat 7 usually hits the front surface portion 11a of the front net 11 and falls. The ball 8 which has come off the front stage net 11 and hits the side part 10b of the base net 10 may bounce back sideways. In this case, the ball 8 hits the side part 11b of the front stage net 11 and falls.
Further, the ball 8 which hits the front portion 10 a after hitting the side portion 10 b of the base net 10 hits the back portion 11 c of the front net 11 and falls.

As shown in FIG. 8A, the front net 11 is suspended by a hook member 18 so as to be swingable in the flight direction of the ball 8.
When the sphere 8 hits the front surface portion 11a of the front net 11, as shown in FIG. 8 (b), the front surface portion 11a is recessed so as to wrap around the sphere 8, and at the same time, the sphere 8 flies around the hook portion 20a as a fulcrum. The entire front net 11 swings.
For this reason, the deformation of the front surface portion 11a of the front net 11 and the shaking of the entire front net 11 are combined, and the impact and vibration when the ball 8 hits are greatly relieved.
After that, the sphere 8 falls downward, but the front net 11 has a shape in which the internal space gradually narrows downward, in other words, an inclined shape that makes it easy to drop the sphere downward. Smooth.
Also in the side surface part 11b and the back surface part 11c of the front | former stage net | network 11, the same impact relaxation and ball catching effect as said front surface part 11a arise.

Since the front net 11 has a three-dimensional shape such as a bag shape, the net 11 has shape retaining properties without providing a border as in the net described in Patent Document 1. That is, the impact mitigating function can be greatly improved only by the shape of the net without edging reinforcement with a member that generates an impact sound.
When the ball 8 hits the lower part of the front net 11, the lower end of the front net 11 is joined and becomes a single piece, so the lower end is bent so as to wind the ball 8, and at the same time the entire front net 11 Shakes to reduce the shock.

Since the front-stage net 11 is narrowed downward, the above-described ball receiving function by the side surface portion 11b is reduced in the vicinity of the lower end portion, but the ball having a height passing through the lower end portion hits the side wall of the ball receiving base 3 and It is accommodated in the cradle 3.
When the bag-like lower end portion is not joined, the lower end portion is irregularly waved, making it difficult to wrap the hit ball with uniform strength.
As the base net 10 and the front net 11, for example, a nylon soft net having an opening width of 2.5 cm can be employed.

As shown in FIG. 9, when the front net 22 has a single configuration, the degree of freedom is too high, so that the ball 8 moves and hits the rear net before the wrapping action is exerted, and an impact sound is generated. . Further, since the width of the front stage net 22 is almost not seen from the side, a function of catching and dropping a ball that bounces at random on the back stage net can hardly be expected.
In addition, as shown in FIG. 10, even when two single front nets 22 are arranged, the hit ball may pass through the front nets and jump out of the ball cradle.

In the present embodiment, the shape of the front net 11 is a bag shape, but is not limited thereto, and may be a shape that does not have the back surface portion 11c.
Moreover, although the lower end part of the front | former stage net | network 11 was made free, the string member which reaches the bottom face of the ball stand 3 is attached to a lower end in the state which does not interfere with the swing operation | movement of the front stage net 11 whole, or a lower end is a string member. You may make it stop with.

Based on FIG. 11 thru | or FIG. 16, the structure of the ball stand 3 is demonstrated.
FIG. 11 is a view of the ball cradle 3 as viewed from above. The ball receiving base 3 includes an inclined receiving surface 23 that receives a ball that falls upon hitting the front net 11 or the base net 10 as a receiving member that receives the hit ball, and a return rail member 5 that returns the ball received on the receiving surface 23 to the batter side. The connecting port 17 to be connected and the guide member 24 that inherits a ball rolled in a certain direction (direction toward the batter side) by the receiving surface 23 and guides it to the connecting port 17 are provided. The guide member 24 is disposed on the lower front side of the receiving surface 23.

The periphery of the receiving surface 23 is a front wall 61 provided on the batter side of the receiving surface 23, a side wall 25 positioned at the left and right ends of the front wall 61, and a curved side wall 26 extending so as to spread outward from the side wall 25 to the net side. And surrounded by
The front wall 61 and each of the side walls regulate the protrusion of the sphere that has fallen on the receiving surface 23.
As described above, the connection ports 17 are provided as connection ports 17R and 17L at two locations on the left and right sides so that the connection ports 17 can be changed according to the difference in the hand of the batter.

The receiving surface 23 as a bottom surface of the ball receiving base 3 is divided into a rear receiving surface 23A positioned below the front net 11 and a front receiving surface 23B positioned between the rear receiving surface 23A and the guide member 24. It is.
FIG. 12 is a perspective view showing a state in which the front wall 61 and the side wall are removed. The rear receiving surface 23A is supported by the rear frame 27, and the front receiving surface 23B is supported by the front frame 28.
The front frame 28 is supported by the rear frame 27 so as to be pivotable by a shaft 29, and the ball holder 3 can be folded by this configuration.

A leg portion 30 is fixed to the lower surface of the rear frame 27 so as to be set in a gap between the inclined rear receiving surface 23 </ b> A and the lower frame 13. A pipe member 31 is fixed to the rear surface of the rear frame 27 with its left and right end portions bent downward.
The end of the pipe member 31 is inserted into the convex portion 12 i shown in FIG. 2, whereby the ball holder 3 is positioned with respect to the lower frame 13.
An L-shaped support member 32 that supports the guide member 24 so as to be tiltable to the left and right is rotatably provided at the central portion of the front frame 28 on the batter side.

13 is a cross-sectional view taken along line XX in FIG. The rear receiving surface 23 </ b> A has a configuration in which a soft sheet material 34 similar to the shutter member 16 is stretched between the roller member 33 supported by the rear frame 27 and the back surface of the rear frame 27.
Two coil springs 35 as urging members are set between the free end of the soft sheet material 34 and the back surface of the rear frame 27.
That is, the slack due to the expansion (thermal expansion) of the soft sheet material 34 due to seasonal temperature change is automatically absorbed and a certain tension is applied. Thereby, the sound and the rolling state when the falling ball 8 is received can be made almost constant.

If the inclination of the receiving surface 23 is steep, the moving speed of the dropped sphere increases and the sound hitting the front surface of the ball receiving base 3 increases, so the inclination of the receiving surface 23 must be moderate. If looseness of the soft sheet material 34 occurs at this moderate inclination, there is a concern that the balls after rolling will not roll.
If a constant tension is always applied as described above, there is no concern that the above-mentioned concern will occur, and a good receiving surface function can be maintained over a long period of time.
The roller member 33 has a configuration in which, for example, a pipe 33a, which is a metal core, is covered with a sponge tube 33b as a flexible member.

The front receiving surface 23B includes two roller members 33 supported by the front frame 28, a soft sheet material 34 stretched between the roller members 33, and a coil spring 35 that applies tension to the soft sheet material 34. Yes.
The looseness of the soft sheet material 34 is automatically absorbed by the same principle as that of the rear receiving surface 23A.
In order to be able to fold the ball support 3, the receiving surface 23 is divided into two in the front and the back, so that the coil spring 35 can be set short, and a good slack correction function can be provided over a long period of time.

As shown in FIG. 14, the guide member 24 is supported by the support member 32 so that the central portion in the left-right direction can rotate, and can move like a seesaw base. By tilting the guide member 24 in one of the left and right directions, the sphere can be guided to one of the two connection ports 17R and 17L.
The guide member 24 is formed by integrating two pipe members 36 and has a configuration in which a sphere is guided by a concave groove 37 formed between the pipe members 36.
The pipe member 36 has a configuration in which, for example, a pipe 36a as a metal core is covered with a sponge tube 36b as a flexible member.

As shown in FIG. 15, a lock mechanism 62 for fixing the position when the guide member 24 is tilted to one side is provided below both ends of the guide member 24. The lock mechanism 62 includes a convex member 62 a provided on the guide member 24 and a receiving member 62 b provided on a corresponding portion of the ball receiving base 3.
The receiving member 62b is configured to elastically deform and accommodate the convex member 62a. The arrangement of the convex member 62a and the receiving member 62b is relative and may be reversed.
The lock mechanism 62 is not limited to the above configuration, and various configurations can be employed.

As shown in FIG. 15 (b), the right end portion of the guide member 24 is pushed in and locked when corresponding to right-handedness. As described above, the shutter member 16 is slid leftward to open the connection port 17R, and the return rail member 5 is connected to the connection port 17R.
When it corresponds to left-handedness, as shown in FIG.15 (c), the left end part of the guide member 24 is pushed in and locked. The shutter member 16 is slid to the right to open the connection port 17L, and the rail member 5 is connected to the connection port 17L.
By providing the guide member 24 as described above, a right-handed or left-handed configuration can be easily set by a simple operation.
Since the unused connection port is closed by the shutter member 16, it is possible to prevent the hit ball from entering the unused connection port.

  In the present embodiment, the position is fixed by the lock mechanism 62 when the guide member 24 is tilted to one side. However, the stationary member and the sponge of the ball holder 3 are used by utilizing the magnitude of the friction coefficient of the sponge tube 36b. The position may be fixed by friction with the tube 36b, and a state in which the sphere can be guided to one of the two connection ports may be maintained. In this way, it is not necessary to provide a lock mechanism, and the configuration can be simplified.

As shown in FIG. 16, the front wall 61 of the ball cradle 3 is supported by the front frame 28 so that the lower end portion thereof is rotatable.
Usually, it is supported by the front frame 28 in a state inclined to the batter side due to its own weight. However, when the hit ball flies downward and hits the front wall 61, it will fall inward of the receiving surface 23 by the contact pressure. To work.
Thereby, compared with the case where the front wall 61 is fixed, the impact when the ball hits can be reduced and the impact sound can be reduced.
The front wall 61, the side wall 25, and the curved side wall 26 are configured to be edged using a soft sheet material in the same manner as the shutter member 16.

The return rail member 5 will be described with reference to FIGS. 17 and 18.
As shown in FIG. 17, the return rail member 5 has an upstream rail portion 5A having one end connected to the ball receiving base 3 and one end detachably connected to the other end of the upstream rail portion 5A, and the other end supplying a ball. It has a two-divided configuration with the downstream rail portion 5 </ b> B connected to the unit 6. That is, it is an assembly configuration in consideration of handling in a narrow room such as between 6 mats.
The upstream rail portion 5A and the downstream rail portion 5B are connected simply by inserting one end of the downstream rail portion 5B into the other end of the upstream rail portion 5A.

The upstream rail portion 5 </ b> A has a configuration in which a plurality (two in this case) of pipe members 38 are integrated by a connecting member 39, and the sphere 8 is guided by a concave groove 40 formed between the pipe members 38.
A height adjusting screw 41 with respect to the floor surface for maintaining a rolling gradient due to the weight of the ball 8 in the return rail member 5 is provided at a connecting portion of the downstream rail portion 5B with respect to the upstream rail portion 5A.

18 is a cross-sectional view taken along line YY in FIG.
The pipe member 38 has a configuration in which, for example, a pipe 38a that is a metal core is covered with a vinyl tube 38b as a flexible member. Each pipe member 38 is fixed to the connecting member 39 by a bolt 42 and a nut 43 that penetrate through the pipe member 38.
When a pipe with relatively low rigidity such as aluminum is used for the pipe 38a, a short pipe with high rigidity may be inserted only in a fixed portion with respect to the connecting member 39 to prevent deformation due to bolt tightening force.
When the sphere 8 rolls while directly contacting the metal pipe, the sound increases due to the irregularities formed by the dimples formed on the sphere 8, but the sound when the flexible member rolls is reduced.

The return rail member in this type of golf practice device is generally formed in a bowl shape as described in, for example, Japanese Patent Laid-Open No. 11-276657, but in the case of a bowl shape, the corner (edge) is exposed. Therefore, there is a risk of injury if used indoors. In addition, if you step on your foot, it may become unusable due to deformation or damage.
On the other hand, if the conveyance path (rolling path) of the sphere 8 is formed by a combination of pipe members having a circular cross section as described above, there is no fear of injury even if they come into contact. In addition, since the pipe member can be elastically deformed by the overall bending, deformation and breakage can be prevented even when it is stepped on with a foot.
In the case of a bowl shape, if the groove width is made larger than the diameter of the sphere in order to ensure smooth movement of the sphere, the sphere moves while meandering, so that the sound becomes louder. If it is a road, there is no such problem because there are no side walls.

Based on FIG. 19 thru | or FIG. 22, the structure of the bulb | ball supply unit 6 is demonstrated.
FIG. 19 is an exploded perspective view of the sphere supply unit 6. The sphere supply unit 6 includes a sphere set unit 6A that supports two or more spheres in series and each sphere rolls under its own weight, and a cover 6B that covers the upper surface of the sphere set unit 6A.
The ball set portion 6A includes a concave base 44, two pipe members 45 fixed to the base 44 in an inclined state, a pressing lever 47 rotatably supported by a column 46 fixed to the base 44, A coil spring 48 as an urging member that urges the pressing lever 47 to return to the original position, and a stopper 49 that regulates the depressed position of the pressing lever 47 are provided.
Rubber legs 50 are provided on the lower surfaces of the four corners of the base 44.

The cover 6 </ b> B has a framework in which a plurality of arch-shaped members 51 are integrally fixed by an elongated plate 58, and is detachably attached to the base 44. Except for the opening 52 for discharging the sphere 8, it is covered with a transparent or perforated soft sheet material 53.
The opening 52 is detachably provided with a discharge guide member 54 that discharges the pressed ball to the outside of the ball set portion 6A as the pressing lever 47 is pressed.
A guide member 55 that guides the ball discharged by the discharge guide member 54 toward the hitting position is provided at a portion facing the discharge guide member 54.

The two pipe members 45 have the same configuration as that of the pipe member 38 of the return rail member 5, and a return rail is obtained by inserting a pipe 45a, which is a metal core, into the other end of the downstream rail portion 5B. It is connected to the member 5 linearly. In other words, the two pipe members 45 serve as extensions of the return rail member 5.
As shown in FIG. 1, since there is a slight degree of freedom in connecting the pipe 45a and the other end of the downstream rail portion 5B, and there is also a degree of freedom in connecting the connection port 17R and the upstream rail portion 5A. In addition, the return rail member 5 can be arranged in an inclined state. Thereby, the sphere supply unit 6 can be made to approach the mat 7 in parallel, and the sphere can be returned to the mat 7.

As shown in FIG. 20, the pressing lever 47 is rotatably supported on the support column 46 by a shaft 56. The pressing lever 47 has an operating portion 47a, an arc shape along the outer surface of the sphere 8, a pressing portion 47b that pushes the leading sphere in a direction intersecting the rolling direction (direction orthogonal), and a pressing portion 47b. And a restricting portion 47c that restricts the rolling of the next ball when the top ball is pressed.
One end of the coil spring 48 is fixed to the back surface of the pressing portion 47 b, and the other end is fixed to the column 46.

In a state before the ball 8 is pushed up by the pressing lever 47, the restricting portion 47c is accommodated in a hole 44a formed in the bottom surface of the base 44 as shown in FIG.
The ball 8 rolling on the return rail member 5 rolls in the concave groove between the two pipe members 45 and comes into contact with the pressing portion 47b of the pressing lever 47 and stops. A soft member 57 such as a sponge for relaxing the contact sound is provided at the contact portion of the pressing portion 47b.

As shown in FIG. 21, for example, when the batter depresses the operation portion 47 a of the pressing lever 47 at the tip of the club, the leading ball 8 a is pushed upward as the pressing lever 47 rotates. During this operation, the forward movement of the next ball 8 b is restricted by the restricting portion 47 c of the pressing lever 47.
When the rotation of the pressing lever 47 proceeds, as shown in FIG. 22, the ball 8 a receives a lateral force intersecting with the pushing-up direction by the discharge guide member 54 with the pushing-up operation of the pressing lever 47, and moves toward the guide member 55. Displace.
The ball 8a rides on a guide member 55 having a guide recess or guide groove at the rotation position where the operation portion 47a of the pressing lever 47 hits the stopper 49, and rolls toward the hitting position of the practice mat 7 due to its inclination.
The pressure lever 47 after discharging the ball 8a automatically returns to the original position by the biasing force of the coil spring 48, and the next ball 8b released from the restriction by the restriction portion 47c comes into contact with the pressure portion 47b.

Since it is only necessary to push down the operation portion 47a of the pressing lever 47 at the tip of the club, the batter does not have to bend or operate with hands or feet, and the ball 8 can be easily set on the practice mat 7 with an easy posture.
Since the rotation position of the pressing lever 47 from which the ball 8 is discharged is determined by the stopper 49, there is no trouble such as the ball 8 being not discharged due to the pushing amount of the operation portion 47a being insufficient.
If a soft member such as a vinyl tube is provided on the outer surface of the operation portion 47a, the contact sound with the stopper 49 can be reduced.

While the leading ball 8a is pushed up by the pressing lever 47, the movement of the next ball 8b is restricted by the restricting portion 47c. Therefore, even if the degree or timing of pressing the operating portion 47a varies depending on the batter, 8b does not move.
Accordingly, there is no case where the next ball 8b enters under the pressing portion 47b and the pressing lever 47 does not move while the pressing lever 47 is raised.
3 and 4 of Japanese Patent Application Laid-Open No. 2007-14741 describe a configuration in which balls are supplied one by one to a mat position by a lock lever biased by a spring.
However, since the conventional configuration described above is a configuration in which the ball is linearly moved and discharged, if the rotation operation of the lock lever is delayed, the movement of the next ball integrally formed with the lock lever is restricted. There is a concern that the next ball will move and double feed before the restricting piece falls.

  In the present embodiment, as described above, the ball is discharged in a direction intersecting with the moving direction of the ball, and the next ball is controlled by the discharging operation restricting portion 47c. Regardless, the above concerns do not arise.

As shown in FIGS. 19 and 22, the guide member 55 has a configuration in which two strips 55a bent in an L-shape are connected and integrated by a lateral plate 55b, and each strip 55a is stopped. It is fixed to the plate 58 with screws 59. A space between the strips 55a serves as a spherical guide groove.
A guide member 55 is fixed to both the left and right sides, and the discharge guide member 54 is detachably attached to one guide member 55.
The discharge guide member 54 includes a mounting portion 54a having a width accommodated in a groove between the strips 55a of the guide member 55, and a guide portion 54b extending so as to rise obliquely upward from the mounting portion 54a, and a lower surface of the mounting portion 54a. Is provided with a fitting portion 54c for fitting to the horizontal plate 55b.

When the discharge guide member 54 is fitted in the groove of the guide member 55 in a state in which the positions of the fitting portion 54c and the horizontal plate 55b are shifted, the fitting portion 54c is fitted into the horizontal plate 55b when the guide member 55 is slid. Is set at a predetermined position where it can be discharged.
By attaching the discharge guide member 54 to any one of the guide members 55, the right-handed type or the left-handed type can be set.
In this embodiment, in order to make the shape of the discharge guide member 54 in FIG. 19 easier to understand, the left-handed type ball supply unit 6 is illustrated, but the discharge guide member 54 is pulled out and attached to the guide member 55 on the opposite side. Thus, the configuration corresponds to the right-handed type.
According to the configuration of the present embodiment, it is possible to easily cope with each type by a one-touch operation without removing a member such as a screw.

  In the present embodiment, the guide member 55 is fixed to both sides and the discharge guide member 54 is attached to any one of the guide members 55. However, the guide member 55 and the discharge guide member 54 are separately manufactured, A detachable configuration in which the base end portion is inserted into the plate 58 from above and attached may be used, or may be fixed detachably with screws, bolts, or the like.

  In this way, one unit can be easily set to both the right-handed type and the left-handed type, which is advantageous in terms of price as compared with the case where each unit is individually manufactured.

The ball return configuration in this type of golf practice apparatus is generally configured to bend the return rail member that extends straight and to guide the striking position at a right angle as described in, for example, Japanese Patent Application Laid-Open No. 2007-14741. It is.
However, in this case, the return rail member may have to be a right-handed or left-handed dedicated type, and takes up space in terms of shape. Furthermore, when the bending angle is close to a right angle, a sphere with momentum in rolling may jump out at the bent portion.

In this embodiment, since the direction of the sphere is changed in the sphere supply unit 6, as shown in FIG. 1, the return rail member 5 and the sphere supply unit 6 can be connected and arranged in a straight line, depending on the curved shape. There is no wasted space.
Further, both the return rail member 5 and the ball supply unit 6 can be used for both the right-handed type and the left-handed type, and there is no fear of the ball jumping out regardless of the degree of inclination of the return rail member 5.

Below, the compact structure of the golf practice apparatus 1 is demonstrated.
FIG. 23 is a side view showing a state where the height of the golf practice net 2 is set close to the upper limit. As shown in FIG. 24, the height of the net can be lowered from H1 to H2 by loosening a fixing screw (not shown) provided on at least one of the guide 12c and the slider 12d and lowering the movable support 12b. it can. This adjustment is made, for example, when not in use or during transportation.
As shown in FIG. 25, by folding the front part of the ball cradle 3 to the net side, the occupied space can be further reduced, the degree of hindrance when not in use can be reduced, and the transportability can be improved. it can.

The front wall 61 of the ball cradle 3 falls to the net side by its own weight with the folding operation. The stability of the ball cradle 3 during folding is ensured by a support rod 60 (not shown in other figures) that is rotatably provided on the lower surface of the ball cradle 3.
The lower end of the support rod 60 is slidably inserted into a cylindrical joint 14 that is rotatably supported by the lower frame 13.
Due to the universal joint fit between the support rod 60 and the joint 14, the dimensional displacement at the time of folding is absorbed, and the ball holder 3 is stably supported. In a state where the ball cradle 3 is not folded, the support rod 60 is positioned in the lower frame 13.
