Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf practice apparatus, and more particularly, to a practice practice that can enhance the practice effect by arbitrarily changing the inclination angle of a bat to produce various conditions of actual fields. The present invention relates to a golf practice apparatus capable of adjusting an inclination angle.

[0002]

2. Description of the Related Art Many golf practice mats designed for golf swing practice have been introduced. Normal,
Conventional techniques used for golf practice indoors include:
Broadly speaking, there are practice apparatuses mainly for putting practice and practice apparatuses mainly for shot practice.

The present invention is applied to a shot practice mat corresponding to the latter. Hereinafter, the practice device refers to a device for practicing a shot, and the related art for practicing such a shot includes the following examples.

[0004] Most training devices are composed of a multi-layer plate, and the upper plate forms an inclination angle by power between the upper plate and the lower plate, and the inclination angle can be arbitrarily changed. However, all of the conventional proposals have a problem that the operation of mechanically adjusting the tilt angle is not mechanically smooth because the power transmission structure for providing the tilt angle is relatively complicated and has a large weight.

In the case of a proposal having a vertical lift axis for providing and adjusting a tilt angle, the lift axis is provided at a fixed distance from the center of the upper plate, so that the shaft is physically located at the shaft fixed position during lifting. As a result, the shaft supporting point moves due to a large displacement, and as a result, the shaft is twisted, and the mechanical operation is not smooth.

[0006] The invention of such an earlier application includes a golf hitting practice device disclosed in Korean Patent Publication No. 97-25644.
In this method, the upper plate serves as both a rough exercise and a fairway exercise, and the central portions of the upper plate and the lower plate are connected by a universal joint, and a fluid cylinder for adjusting the inclination angle is connected to the upper plate and the lower plate. Are provided at four locations on the outer periphery.

In the invention of this prior application, since the fluid cylinder is used as a drive device for adjusting the angle by using the upper plate as a slope, the training device must be connected to the fluid supply device without fail, and the device is complicated. There was a disadvantage that was difficult to manage.

On the other hand, according to Korean Patent Publication No. 96-13407, which describes a golf practice bat capable of adjusting the inclination of a scaffold, another plate is disposed between an upper plate and a lower plate to provide a mechanical jack. It is composed of multiple layers, and the inclination angle in the left-right direction and the front-back direction is adjusted by the attractive force to provide the inclination angle.

Although a servomotor or a fluid jack is used to generate power, it goes without saying that the configuration of a plurality of jacks and power equipment is complicated.
There is a drawback in that the power consumption is extremely large and the weight increases when adjusting the angle, so that installation and maintenance are difficult.

On the other hand, the training scaffold disclosed in Korean Patent Publication No. 97-73641 is formed by laminating and connecting a plurality of layers with a slanted disk as a center axis by bearings, and forming a gear on the outer periphery of each slanted disk. And a speed reduction motor having a pinion for transmitting power is mounted on each of them, and is embedded in the floor of a golf driving range so that an inclination angle is obtained by the amount of rotation of the stacked inclined disks.

On the other hand, in the training apparatus of Korean Utility Model Publication No. 91-2300, another central plate is disposed between an upper plate and a lower plate, and a disk is placed on each of the upper plate and the central plate. A large semicircular worm wheel that traverses is mounted, and the upper plate is supported at two points against the center plate, and the center plate is supported at two points against the lower plate and shifted 90 degrees from the upper plate. The worm wheel is meshed with a worm gear of a drive motor.

Nos. 97-73641 and 91-2
Both of the 300s are also very heavy,
Since it is difficult to lay and work as a fixed facility, there is a problem that installation and maintenance are difficult, and it has been practically difficult to apply.

[0013] In addition, in all of the conventional proposals, a golf ball supply device is exposed or protrudes on one side of a training device because a device for supplying a golf ball is separately installed and used.
It is inconvenient at the time of the shot, and there is no tee for the shot at all, but even if it is protruded at a certain height, the practice effect is inferior, so it is inconvenient to use, and the angle adjustment with high precision It was difficult, and it was impossible to perform various productions of the actual field.

[0014]

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The technical concept of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a conceptual external configuration diagram of the present invention.

The training apparatus according to the present invention comprises a lifting tee 45.
A ball feeder 40 that rises and falls with 0, and a controller 60 that sets and displays the tilt angle and controls the supply of the ball

It includes a plate assembly 20 and a telescopic cover 70 for closing a side space between the upper plate assembly and the lower plate assembly. Here, the lifting assembly is indicated by reference numeral 30 in FIG.

The elevating assembly for adjusting the inclination angle has four elevating points provided at equal angles on a concentric circle with respect to the center axis of the upper plate. In other words, two points 180 degrees opposite each other are paired and driven up and down in the opposite direction at the same distance,
The line connecting the pair of drive and driven sides is formed to be orthogonal to the line connecting the other pair of drive and driven sides.

Therefore, when one point out of a pair of two points facing each other with the same elevating distance rises, the other point descends, and the same operation is performed at another pair of two points orthogonal to each other. Ascending and descending in all directions 360 degrees from the reference.

An embodiment for specifically implementing the training apparatus will be described. 2 to 11 show one embodiment of the present invention, and FIG. 2 is a plan view showing a configuration in which an upper plate assembly is removed.

According to a preferred embodiment of the present invention, the upper plate assembly 10 has an upper plate in which a radial support rod 12 and an artificial turf mat are joined, and the lower plate assembly 20 is the same size as the upper plate. , A support rod 23 for fixing the substrate to the outer frame, and a support plate 2 fixed to the center of the substrate at a distance vertically from the substrate.

The elevating assembly 30 fixed to the substrate 21
Are a pair of drive-side elevating assemblies 31 and a driven-side elevating assembly 32 each of which is interlocked with one of the driving-side elevating assemblies 31.
Consists of Each drive-side elevating assembly 31 has a rectangular gear box 310 and a worm wheel 313 rotatably fixed by a bearing 314 in the rectangular gear box 310. Here, the worm wheel 313
In the above, a lead screw engagement nut is formed in a center hole to form a horizontal gear. The drive-side elevating assembly 31 has a drive shaft 311 that forms a worm 312 by a part housed in the gear box 310 so as to mesh with the worm wheel 313 and penetrates the gear box 31. The worm wheel 313
The lead screw 315 which is screwed into the nut formed therein while penetrating through the center hole is axially connected by a universal joint 316 to a flange 317 whose upper end is connected to the upper plate assembly 10.

The drive-side elevating assembly 31 further has a deceleration motor 318 one end of which is directly connected to the drive shaft 311. On the other hand, the driven-side lifting / lowering assembly 32 is connected to the other end of the driving shaft 311 to which one end of the driving-side lifting / lowering assembly 31 is connected. The worm 312 at both ends of the drive shaft 311 has substantially the same configuration as that of the assembly 31, and is configured so that the rotation direction thereof is opposite to that of the pair of worm wheels 313 facing each other in opposite directions. You.

As shown in FIG. 3, when the deceleration motor 318 is driven, the drive shaft 3 directly connected to the drive shaft 3 is adjusted by operating the elevating assemblies 31 and 32.
By rotating the worm wheel 11, the worm wheel 313 is rotated by the worm 312 of the shaft portion, whereby the lead screw 315 screwed to the center hole nut of the worm wheel 313 is moved up and down. Then, the upper plate assembly 10 forms an inclination while moving up and down.

Here, the driving and driven side elevating assemblies 31 and 32 have the same operating principle, but are meshed so that they are driven in opposite directions by a common driving shaft 311. Act as a pair of lifting assemblies, each lifting in the opposite direction.

When the upper plate is inclined from the horizontal state by the vertical axis of the lead screw 315, the assembly point between the upper plate and the lead screw 315 is generally likely to be pushed by a fixed gap from the lead screw 315 axis. There is such a physical gap in the upper plate assembly 10
Is caused to pivot around the center of the plate. However, in the present invention, since the physical gap that can be generated from the support axis point is absorbed by the universal joint 316, eccentricity due to mechanical operation can be effectively prevented.

The lead screw 315 is connected to the upper plate assembly 10 through a universal joint 316.
Are fixed to the upper plate assembly 10 by being fixed to the flange 317, so that they can move up and down only by rotation of the worm wheel 313 without rotating.

Here, since the drive shaft 311 is perpendicular to the other pair of drive shafts 311 adjacent to each other, the drive shafts 311 are vertically arranged with a difference in shaft installation height so as not to interfere with each other. Correspondingly, the position of the worm wheel is also designed with a difference in height.

In other words, since a pair of vertical lifting assemblies form a combination of vertical distances in eight directions of front, rear, left, right, and diagonal directions, the tilt can be made in all directions of 360 degrees.

Next, the ball supply means applied to the present invention will be described. The ball supply means includes the upper plate assembly 10

In the above-described ball feeder, when a large number of balls are stored in the container 510, the balls are guided so as to fall in a line along a slope, and the balls are entangled in the ball inflow process. To prevent this, the rotating rod 512 is rotated intermittently.

The balls supplied in a line to the outlet 511 are:
The connecting pipe 52 is pushed by the push 521 of the horizontal transfer section 520.
A force is exerted which pushes the ball in a row to 3 so that the ball is supplied continuously and continuously.

The ball supplied to the connecting pipe 523 is supplied to the inflow port 422 of the internal ball feeder 40, and at this time, the lifting rod 415 which is being lowered by the push 423.
Is supplied with one ball. When the ball is supplied in this way, the lifting rod 415 is raised through the link 416 of the solenoid 417, and the ball gripping arm 411,
The ball can be correctly positioned between 412.

The gripping arms 411 and 4 to which the ball is supplied
Numeral 12 grasps the ball by the power of the solenoid 413, and rotates the shaft 421 by driving the motor 419, so that the pinion 420 raises the rack gear shaft 418,
The ball gripping arm assembly rises from the frame 400 to the upper part of the upper plate assembly 10. When the lifting is completed, the power of the swing motor 414 causes the ball gripping arm 4
11 and 412 are turned, and one ball is placed on the tube 452 of the tee 450 at the turned position.
The ball gripping arm descends in the reverse order,
By repeating such a lifting process, the next ball is continuously supplied.

The elevation of the ball supply housing 410 is controlled in proportion to the elevation of the tee 450, the elevation of which is adjusted according to the type of shot (tee shot, second shot, putting, etc.). .

FIGS. 12 to 16 show another embodiment of the present invention, and FIG. 12 is a structural view in a side sectional view. 12 to 16, the same members as those in FIGS. 2 to 11 are denoted by the same reference numerals.

The lifting / lowering assembly 30a of the lifting / lowering means fixed to the substrate 21 includes a pair of driving-side lifting / lowering assemblies 33 and a driven-side lifting / lowering assembly 34 which is interlocked with one of these driving-side lifting / lowering assemblies. Each drive-side elevating assembly 33 has a rectangular gear box 330 and a worm wheel 333 rotatably fixed in the gear box 330 by a bearing 334. Here, the worm wheel 333 has a lead screw meshing nut formed in a center hole, and forms a gear in the horizontal direction. In addition, the drive-side elevating assembly 33 has a drive shaft 331 that has a worm 332 at a portion housed in the gear box 330 and extends through the gear box 330. The worm 332 is screwed with the worm wheel 333. Also, a lead screw 335 screwed into a nut formed through the center hole of the worm wheel 333.
Is a guide groove 3 formed on one side by shaving in the vertical direction.
The guide 337 is fixed to the gear box 330 so as to be fitted into the guide groove 335a. The upper end of the lead screw 335 is axially connected to the upper plate assembly 10 by a ball joint. FIG.
As shown in FIGS. 15A and 15B, the ball joint has a ball 336 attached to the upper end of a lead screw 335 and a slide member 339a pivotally coupled to the ball 336. Here, the bearing 339 for supporting the ball joint is connected to the upper plate assembly 1.
However, the bearing 339 has a fixed gap 339d between the bearing 339 and the upper plate assembly 10, and a slide member 339a to which a ball joint is coupled is inserted into this gap. It is elastically supported by 339b.

The drive-side elevating assembly 33 further has a deceleration motor 338 one end of which is directly connected to the drive shaft 331. On the other hand, the driven-side lifting / lowering assembly 34 is connected to the other end of the drive shaft 331 whose one end is connected to the driving-side lifting / lowering assembly 33, and the drive-side lifting / lowering assembly is omitted except that the deceleration motor is omitted. The worm 332 at both ends of the drive shaft 331 has substantially the same configuration as that of the assembly 33, and is rotated in the opposite direction by being meshed with the pair of worm wheels 333 in opposite directions. .

The support plate 24 formed at the center of the lower plate assembly 20 has a central shaft 340 having a ball joint 342 formed at an end thereof, and a bearing 344 fixed at the center of the upper plate assembly. Are axially connected by a ball joint.

As shown in FIG. 13, when the deceleration motor 338 is driven, the drive shaft 331 directly connected thereto is rotated to adjust the angle of the upper plate assembly 10 by operating the elevating assemblies 33 and 34. The worm 332 causes the worm wheel 333 to rotate, whereby the lead screw 335 screwed into the center hole nut of the worm wheel 333 moves up and down. Then, the upper plate assembly 10 forms an inclination while moving up and down.

Also in this case, similarly to the above-described embodiment, the driving and driven-side lifting / lowering assemblies 33 and 34 have the same operating principle, but are driven by a common driving shaft 331 in mutually opposite directions. And thus act as a pair of lifting assemblies, each raising and lowering in the opposite direction.

On the other hand, the lead screw 335 is provided with a guide 33 fitted in a vertically provided guide groove 335a.
The rotation is forbidden by 7 and it moves up and down only in the vertical direction.
This guide is provided to prohibit the rotation of the lead screw 335 caused by the formation of a rotatable ball joint at the end of the lead screw 335.

On the other hand, when the lead screw 335 is moved up and down in the vertical direction, there is a possibility that an assembly point with the upper plate may be pushed by a fixed gap on the same axis. This is due to the turning motion about the center. Therefore, in the present embodiment, the physical gap generated at such a support point is set to the ball joint 336.
When the eccentricity occurs by making the movable by the slide member 339a of the bearing 339 and elastically supported by the spring 339d, as shown in FIGS. 15 and 16, the slide member moves in the eccentric direction and the vertical axis direction remains as it is. It is prevented from being maintained. Of course, the return is effected by said spring elastic force, the spring playing a role of elastic function and torsion tolerance.

Of course, as described above, the drive shafts 331 are vertically arranged at different shaft heights so as not to interfere with another pair of adjacent drive shafts 331 and are formed to be orthogonal to each other. 17 to 20 show still another embodiment of the present invention, and FIG. 17 is a side view of the configuration.

That is, the internal ball feeder 40a has a ball gripping arm assembly incorporated in the ball supply housing 410, and a rack gear 430 fixed at the center of the rear surface of the housing 410.
It is engaged with a pinion 432 attached to a motor 431 fixed to the upper frame 400, and is vertically moved up and down by rotation of the motor 431, whereby the ball supply housing 410 is vertically moved up and down. In addition, a guide shaft 433 fixed to the frame 400 is formed on the front surface facing the rack gear, and the guide 434 is fitted to the guide shaft and fixed to the housing 410, so that the guide is guided when ascending and descending.

In this case, the driving force of the motor 431 is transmitted to the rack gear 430 formed at the center of the housing when the ball supply housing 410 is moved up and down. It has the same function as the internal ball feeder described above, except that it acts so as to be guided by the guide shaft 433 by a guide 434 provided on the opposite side of the front face in order to prevent the eccentricity from lifting and lowering. The details are omitted.

The control operation of the control unit as described above will be described in detail below. This further clarifies the operation of the present invention.

In FIGS. 30 to 37, when the operating power is input, the sensor of the tee raising / lowering limit detecting section 636 detects the position of the tee and sets the tee to the lowering position. The arm is correctly positioned in the internal ball feeder housing by the sensor detection of the detecting unit 634 which detects the position of the ball gripping arm for feeding, and the ball feeding housing is positioned at the lowered position.

At this time, the push motor is driven until the ball detection sensor of the external ball feeder completely fills the ball in the connecting pipe in a state where many balls are put in the external ball feeder, and the balls are transferred from the external ball feeder. It is controlled to be filled from the ball inlet of the internal ball feeder along the connecting pipe.

Thereafter, the X-axis lifting / lowering motor is driven clockwise until the X-axis is maintained horizontal, and the Y-axis lifting / lowering motor is driven counterclockwise until the Y-axis is maintained horizontal. As a result, the initialization of the golf practice apparatus capable of adjusting the inclination angle is completed.

When the initialization is completed, a subroutine of a key input process and a ball supply process is executed. If a trouble occurs during the execution of each subroutine, the trouble is detected and controlled to stop all the drive motors.

As shown in FIGS. 32 to 34, the key input process is performed in the X-axis direction or the Y-axis direction in accordance with each input of eight-direction keys (key 1 to key 8) forming the inclination of the upper plate assembly. Is driven forward or reverse to rotate the motor in the corresponding direction, and when the input of the key 9 is detected, the upper plate assembly is controlled to be positioned horizontally.

When input of the keys 11 and 12 is detected,
The control unit drives the tee drive motor so as to raise and lower the tee, and performs control to raise and lower the tee. When the input of the key 10 is detected, the key 10 process is executed, which is shown in FIG. This is a drive control for placing the ball of the internal ball feeder on the tee, and the process of raising the ball supply housing in a standby state where one supplied ball is placed on the lifting rod, When the overcurrent of the motor is detected, the motor is reversely driven to lower the housing to the initial position. this is,
This is for re-driving assuming that an operation exceeding the ascending control limit or ascending or descending abnormality has occurred.

When a signal from a sensor for detecting the correct position of the raised housing is sensed, the lifting rod solenoid built in the ball supply housing protruded above the upper plate assembly is turned on to hold the ball. It is controlled so that the ball is held at the position and the ball holding arm solenoid is turned on to hold the ball.

When the ball is gripped, the arm is pivoted out of the housing, and the position of the tee coincides with the ball at the pivoted position. Therefore, the ball gripping arm solenoid is turned off and the ball is placed on the tee. After that, the swiveled gripping arm is stored in the original position, and the raised ball supply housing is controlled to be stored again in the upper plate assembly.

As described above, the sequential supply of balls into the ball supply housing is controlled and executed by the ball supply process shown in FIG. According to this, when the ball arrival detection sensor that detects the ball supply state to the external ball feeder detects a ball, the external ball feeder push motor is controlled to drive the ball for a fixed time to press and supply the ball. Then, in order to supply the ball to the elevating rod position of the internal ball feeder, the ball push motor is driven one rotation to the initial position to control one ball to be supplied. When it is detected, the push motor is rotated in the reverse direction so as to be in the drive initial position and is controlled so as to be supplied again.

If the ball arrival detection sensor does not detect a ball, the push motor of the external ball feeder is driven to supply the ball with a full supply path.
It is configured to detect that the push motor cannot rotate and generate an overcurrent, and execute control to temporarily reverse the push motor.

As a result, the balls are continuously and continuously supplied in a state where the balls are arranged in a line and are closely contacted with no gap between the balls. FIG. 37 shows an error check process performed by the control unit of the present invention.

This is for protecting the device by controlling the lower limit point of the upper plate assembly and controlling the driving motor and the like during operation to make an emergency stop.
A number of limit switches forming the sensor unit 640 are disposed on the outer frame of the lower plate assembly, and the limit switches detect the upper plate inclination in eight directions. The limit switch is provided to be at least outside the normal operating angle (± 10 °) range of the upper plate assembly. This allows
When the operation is detected for any one of the limit switches, the upper plate assembly driving motor in the X and Y axis directions is driven in the opposite direction to the limit switch detection direction to stop, and the The control can be performed such that the arm motor, the tee drive motor, and the push motor are all stopped.
