Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention, by simply pressing the two types of pedals provided on the front of the device to separate the balls, when practicing a tee shot, one ball is automatically placed on each tee, and an iron shot without using the tee. The present invention relates to a ball feeding device for golf practice, which is capable of continuously discharging an arbitrary number of balls on a play mat when practicing a golf course.

[0002]

[Prior art]

 11 and 12 exemplify the configuration of a conventional automatic ball feeder for tee shot practice. Numeral 50 is a play mat on which the player stands and plays. A tee 51 on which a golf ball is placed is erected at a predetermined position. Reference numeral 60 is an automatic ball feeder, which is fixed to the floor of the practice area adjacent to the play mat 50. This automatic ball supply device 60 rolls a ball feeding trough 62 from a ball reservoir 61 to reach a delivery portion 63 at the end thereof, and a ball transfer arm 64 mounted at the base end of the ball transfer arm 64 attached to the delivery portion 63. It is designed to supply one ball to each side. The ball transfer arm 64 is pivotally supported at a position near the base end thereof on a horizontal support shaft 65 and can be vertically rotated by a motor (not shown). A ball drop arm 66 is provided at the front end and a rear end is provided at the rear end. Is provided with a stopper 67 for moving the balls one by one onto the arm. Reference numeral 70 denotes a ball detection sensor incorporated in the automatic ball supply device 60, which irradiates the ball on the tee 51 with infrared rays to detect the presence or absence thereof. The ball transfer arm 64 normally takes a standing posture that does not interfere with the swing as shown in FIG. Then, when a ball supply switch (not shown) is turned on, the motor operates and the ball transfer arm 64 pivots downward and falls sideways, and the stopper 67 acts to supply only one ball to the base end side. The formed ball rolls on the ball transfer arm 64 to reach the falling ball opening 66, and is dropped and placed on a tee 51 located immediately below the falling ball opening 66. After the ball is dropped, the ball transfer arm 64 is returned to the standing posture again by the motor and automatically moves to the next ball-sending operation. On the other hand, a mechanism for intermittently ejecting balls one by one for practicing tee shots and a mechanism for continuously ejecting balls for practicing iron shots, etc. were incorporated, and the lever of the attached supply switching mechanism was operated. By doing so, an automatic ball supply device is also considered that can be switched to any of the discharge states.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional tee shot practice device can be used for iron shots without tees, but the ball transfer operation by the ball transfer arm 64 is intermittent. For me, it's awkward. However, about 3/4 of the total number of hits is devoted to the iron shot practice, which is the average practice of the player. In addition, the ball transfer arm 64 swings up and down to replenish the ball each time the ball on the tee runs out, regardless of the player's swing motion. It is not uncommon for a club to hit the ball transfer arm by coincidence with the lowering motion. In addition, since a motor is used to operate the ball transfer arm, the structure is complicated, the manufacturing cost is considerably high, and there are considerable drawbacks such as installation cost and maintenance and inspection cost after installation. There is. On the other hand, in the conventional device that can be used for both tee shot practice and iron shot practice, the operation of switching the way of the ball is considerably troublesome. Therefore, the purpose of the present invention is that it can be used for both practice of tee shots and iron shots, and the operation of switching the ejection state of the ball becomes unnecessary, and there is a risk that the returning club immediately after the swing motion will hit the ball transfer arm. It is to provide a ball supply device for golf practice that can solve the above problems, and the manufacturing cost of the device is significantly lower than the conventional one, and maintenance and inspection can be almost eliminated.

[0005]

[Action]

 In a state where the ball reservoir 3 is filled with balls and is in a standby state, the balls in the ball reservoir 3 are divided into two parts, a main rail 6A on the rear side and a sub rail 6B on the front side, and are inclined forward and downward. The ball group falls on the ball transfer rail 6 and moves forward, but in the divided portion, the rear end of the sub rail 6B has a step shape higher than the front end of the main rail 6A. The step is blocked at the step. In this state, when the main pedal 11 is pushed to practice the tee shot, the main link 9 works to lift the front end side of the main rail 6A, and the frontmost ball of the ball group aligned on the main rail 6A is the auxiliary ball. Roll on rail 6B. At the same time, in the second ball, the stopper 17 attached to the sub link 9 stands against its front surface to prevent rolling, and one ball is directed from the front end of the sub rail 6B toward the main ball exit 4. Sent out. Then, the ball transfer device 30 attached to this outlet receives the delivered ball and transfers it onto the tee standing on the play mat. When the auxiliary pedal 12 is pressed to practice iron shots without using the tee, the auxiliary link 10 works to lift the rear end side of the auxiliary rail 6B upward, and the auxiliary rail 6B waits in line on the main rail 6A. The forward blocking state of the ball group is released, and the ball is continuously delivered from the front end of the main rail 6A toward the sub ball outlet 5 and supplied onto the play mat laid in front of it. During practice of the tee shot, when the standing position of the tee is displaced from the initial position, the tip position adjusting means 41 is operated to drop the guide portion at the tip of the arm with rail 31. It is easy to return the positional relationship between 36 and Tay to the normal state. Furthermore, if a deeper saucer-shaped fixing tool 45 made of rubber is fixed on the floor surface of the golf driving range by means of bolts or the like, the ball feeder will have its lower end in the recess of this fixing tool 45. The floor surface can be easily attached and detached simply by inserting it.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 9. First, a schematic structure of the ball supply device A of this embodiment will be described. As shown in FIGS. 1 and 2, a frame 2 covered with a horizontally long and vertically flat housing 1 is provided. The upper part of one end of the housing 1 in the longitudinal direction is provided with a ball reservoir 3 whose upper surface is open, and the other end of the front face is provided with a main ball outlet 4 for practice of tee shots and an practice of practice such as an iron shot. The sub ball outlets 5 are provided at a predetermined interval. A gutter-shaped ball transfer rail 6 is attached to the frame 2 and extends from the ball reservoir 3 toward the main and sub ball outlets 4 and 5 while being inclined forward and downward. The ball transfer rail 6 is divided into two parts near the front end, a main rail 6A on the rear side and a sub rail 6B on the front side. Then, the rear end of the main rail 6A and the front end of the sub rail 6B are pivotally supported by the support shafts 7 and 8, respectively, so that both the main and sub rails 6A and 6B can be pivoted up and down around the respective support shafts. There is. Further, the main rail 6A and the sub rail 6B are fitted with a main link 9 and a sub link 10 for rotating these rails respectively, and a main pedal is provided at each free end of the main link 9 and the sub link 10. 11 and the auxiliary pedal 12 are assembled. In this assembly, the front end of the main rail 6A is normally positioned slightly below the rear end of the sub rail 6B, and a step is formed between these two ends. In addition, a ball transfer device 30 is installed in the main ball outlet 4 for receiving the balls discharged from the outlet and mounting them on a tee 51 standing on a play mat 50.

Next, a detailed configuration of the ball supply device A will be sequentially described. As shown in FIG. 3 and other figures, the main link 9 for rotating the main rail 6A is composed of one lever 13 made of a metal wire that acts like a lever, and has a longitudinal intermediate portion a at the frame 2 Is supported by. The main rail 6A also constitutes a part of the main link 9. One end of the lever 13 is applied to the lower surface on the front end side of the main rail 6A to support the main rail 6A. The main pedal 11 is attached to the other end of the lever 13.

As shown in FIG. 3 and other drawings, the auxiliary link 10 for rotating the auxiliary rail 6 B has a rotating bar 15 whose middle portion is pivotally supported by a column 14 standing on the frame 2. A connecting bar 16 pin-connected to one end of the rotating lever 15 in a hanging shape, and a sub-rail 6B having an intermediate portion b connected to the lower end of the connecting lever 16 by a pin. A sub-pedal 12 is attached to the other end of the rotary bar 15, and a stopper 17 for stopping a ball, which will be described later, is vertically provided at an intermediate portion of the lower surface. Further, a roller 18 for preventing balls from being caught is attached to the rear end of the sub rail 6B. A gap of a predetermined width is provided between the front end of the main rail 6A and the rear end of the sub rail 6B.

Above the front side portion of the main rail 6A, the metal that falls from the ball reservoir 3 onto the main rail 6A and rolls toward the front end thereof is aligned in a row without stacking. A guide member 19 for alignment is provided by bending the strip into a V shape. Directly below the end of the main rail 6A, there is provided a guide gutter 21 for guiding the ball dropped from this end to the outside of the housing 1 through the sub-ball outlet 5. On the other hand, a guide gutter 22 that guides the ball dropped from the end to the main ball outlet 4 is provided at the tip of the sub rail 6B.

Next, the structure of the ball transfer device 30 will be described with reference to FIGS. 5 to 8. The ball transfer device 30 is attached to the main ball outlet 4 as shown in FIG. 1, receives the balls discharged one by one from the main ball outlet 4, and automatically receives them on the tee 51 on the play mat 50. It is composed of an arm 31 with a rail that plays a role of mounting the arm 31 and a mounting frame 32 to which the arm 31 with a rail is assembled. As shown in FIG. 6, the arm 31 with rails is in the form of an arm having a predetermined length, and its rear end (closer to the right in the figure) is pivotally supported by a horizontal support shaft 33 so as to be vertically rotatable. The portion that becomes the upper surface when it is rotated sideways is the rolling rail 34 that transfers the ball. The portion of the arm 31 with rails on the rear side of the horizontal support shaft 33 is formed into a fan-shaped or triangular-shaped weight portion 35. Further, at the tip of the rolling rail 34, there is provided a drop guide portion 36 in the shape of a short cylinder for dropping the ball toward the tee 51.

The rail-equipped arm 31 is set such that the weight balance between the front and rear of the horizontal support shaft 33 is slightly heavier on the rear side. Therefore, when the ball is not supplied at all times, the weight 35 is automatically rotated so as to face downward and takes the standing posture shown by the solid line in FIG. The mounting position relationship of the ball transfer device 30 with respect to the main ball outlet 4 is such that the balls discharged one by one from the main ball outlet 4 are different from the horizontal support shaft 33 of the arm 31 with rail in the standing state. It is set so as to collide with the rolling rail 34 at the position on the minute side (upper side in the figure).

Therefore, when the ball discharged from the main ball outlet 4 collides with the arm with rail 31 in the upright state, the impact causes the arm with rail 31 to tilt forward around the horizontal support shaft 33. The ball is placed on the rolling rail 34. As a result, the front arm of the horizontal support shaft 33 becomes heavier than the rear side, and the arm 31 with rail is pivoted to the slightly sloping-down side-down position as shown by the chain double-dashed line in FIG. 5 (not shown). The ball that rolls on the rolling rail 34 and reaches its front end is blocked by the fall guiding part 36 and falls onto the tee 51 located immediately below it. It has become.

Therefore, it is necessary to set the arm with rail 31 so that when the arm with rail 31 is turned sideways, the drop guide portion 36 at the tip of the arm 31 is correctly brought to a position directly above the tee 51. Alternatively, the tee 51 may be struck frequently during use of the ball supply device, causing play in the mounting portion thereof, and the tee 51 may deviate from the initial standing position. Therefore, it is extremely desirable that the arm 31 with rails can easily adjust the position of the drop guide portion 36 at the tip thereof. As a countermeasure, the ball transfer device 30 is provided with tip position adjusting means 41 for finely adjusting the mounting position of the rail arm 31.

As shown in FIGS. 5 and 7 to 9, the tip position adjusting means 41 is provided with a main frame 32A having a U-shaped cross section and a short gutter shape, and a main frame 32A. The movable frame 32B is movably fitted to the main frame 32A, and an adjusting mechanism for displacing the rail-equipped arm 31 assembled to the main frame 32A in a three-dimensional direction. The mounting frame 32 comprises a combination of both main and movable frames. The rail-equipped arm 31 has both ends of the horizontal support shaft 33 loosely fitted in shaft fitting grooves 32a provided on both left and right sides of the movable frame 32B. Therefore, the arm 31 with rail can be easily removed and replaced. The main frame 32A is attached to the front surface of the housing 1 via a hinge 37 at the rear upper end thereof, and is rotatable up and down around the hinge axis. Then, as shown in FIG. 7, by mounting the turning screw 38 of the main frame 32A between the bottom surface member 32b of the main frame 32A and the front wall of the housing 1, the horizontal position of the horizontal support shaft 33 is adjusted. It is possible to adjust.

Further, as shown in FIG. 8, by inserting the thumbscrews 39 projecting on the left and right sides of the movable frame 32B into the horizontal elongated holes 32c provided on the left and right sides of the main frame 32A, the horizontal support shaft 33 is formed. Can be displaced back and forth. Further, as shown in FIG. 9, by inserting a thumbscrew 40 projecting from the bottom of the movable frame 32B into a shaft hole provided in the bottom of the main frame 32A, the main frame 32A and the movable frame 32B are separated from each other. By utilizing the fitting gap, the horizontal support shaft 33 can be vibrated in the left and right directions.

FIG. 10 shows an example of a fixing tool for fixing the ball supply device A to the floor surface on which it is installed. This fixing tool 45 is made of rubber and has a deep saucer shape, and the leg-shaped portion 1a with both ends of the housing 1 protruding downward or the leg of the frame 2 is simply inserted into the recess. Thus, the ball supply device A can be very easily fixed to the floor surface on which it is installed, and can be easily removed if necessary.

Next, the operation of the above configuration will be described. First, in order to install the ball supply device A on the floor of a golf driving range, as shown in FIG. 1, the leg portions 2a provided at both ends of the frame 2 are fixed to the floor with bolts. The ball transfer rail 6 is in the state shown in FIG. 2 when the apparatus is on standby. That is, the front end of the main rail 6A is located slightly below the rear end of the sub rail 6B, and a step is formed between both ends of the sub rail 6B, so that the ball falls from the ball reservoir 3 and is inclined forward and downward. The balls rolling in a row on the transfer rail 6 toward the tip end thereof are in a state of being blocked from hitting the rear end of the auxiliary rail 6B.

Therefore, when practicing the tee shot, when the main pedal 11 is pushed by the head of the golf club or the like, the lever 13 is rotated counterclockwise as shown in FIG. 3, and the main rail is rotated. Lift the front end of 6A. Therefore, one of the tips of the balls aligned on the main rail 6A is rolled and transferred to the sub rail. At the same time, the stopper 17 stands in front of the second ball from the front, and the rolling forward of the second to rear balls is blocked. The ball transferred to the sub rail 6B rolls as it is, falls from the tip of the sub rail onto the guide trough 22, and is discharged from the main ball outlet 4 to the outside of the housing 1. This discharge ball is automatically placed on the tee 51 as described above. When the ball on the rail-equipped arm 31 moves over the tee, the rail-equipped arm 31 naturally returns to the standing posture by the action of the weight portion 35, and is kept in this state until the main pedal 11 is pushed next time. It Therefore, there is no possibility that the return club at the time of swing accidentally collides with the rail-equipped arm 31.

When practicing iron shots or the like, when the sub-pedal 12 is pressed, the sub-link 10 works to lift the rear end side of the sub-rail 6B as shown in FIG. The aligned balls on 6A continuously drop from the tip of the main rail 6A onto the guide gutter 21 directly below the main rail 6A, pass through the auxiliary ball outlet 5, and reach the play mat 50 installed in front of the ball supply device A. Runs up. To stop the discharge of the balls, the pressing force of the auxiliary pedal 12 may be released.
