Description

Swing plate for golf practice with tilt adjustment {SHOT PLATE CAPABLE OF SLOPE REGULATION FOR GOLFPRACTICE}

The present invention relates to a swing plate for golf practice with an adjustable inclination, and more particularly, to a swing plate for golf practice in which a footrest on which a user steps on is not shaken and can be curved in various forms.

In general, in golf courses, golf shots are simply played on flat ground, but in many cases, golf shots are played in various terrain conditions, such as downhill slopes, uphill slopes, gentle slopes, steep slopes, and wave-like curves.

In this way, in a golf driving range or screen golf system, a swing plate is provided as a batting seat for a user to play a golf shot so that users who practice golf can practice golf shots in various terrain conditions as well as on flat land. do.

The currently commercialized swing plate is not only tilt-adjusted so that the footrest that the user steps on can be inclined to one side, but also has a plurality of divisions so that each part of the footrest can be inclined at different angles. A 'divided driven swing platform (Republic of Korea Patent Registration No. 10-2352500)' composed of plates has been proposed.

In the conventional swing platform, a plurality of dividers are arranged in succession in the horizontal and vertical directions, and each divider is configured such that the inclination angle is controlled by a separate drive actuator, so that the inclination of each part of the scaffold can be adjusted differently. There is an advantage.

However, the conventional swing platform has a disadvantage in that a sense of incongruity with the actual field is very large because a corner occurs between two neighboring dividers when each divider is inclined at a different angle. In addition, since the conventional swing platform is installed at an angle such that the drive actuators for driving each divider are inclined with respect to the ground, when the user stands on the scaffold, the scaffold shakes, making normal swing practice impossible, as well as over a long period of time. When a large load is repeatedly applied to the manual actuator, there is a disadvantage in that the actuator may be damaged.

A 'swing plate for golf practice (Republic of Korea Patent Registration No. 10-1226114)' has been proposed in which the actuator is erected vertically to prevent damage to the actuator, but the swing plate as described above has a piston end of the actuator. Since it is not fixedly coupled to the scaffold, there is a disadvantage in that the scaffold shaking problem is still not solved.

In the swing plate for golf practice according to the present invention, each part of the footrest 400 can be bent in different directions and angles so that various slopes of the actual field can be implemented indoors such as an indoor golf driving range or a screen golf driving range, and a stable swing The biggest feature is that the scaffold 400 is firmly fixed without shaking so that practice is possible.

That is, the swing plate for golf practice according to the present invention includes a base frame 100 seated on the ground, a cylinder tube 210 fixedly coupled to the base frame 100, and a piston drawn upward from the cylinder tube 210 The connection angle between the plurality of actuators 200 composed of 220, the footrest 400 located above the plurality of actuators 200, and the piston 220 and the footrest 400 is changeable A plurality of joint units 300 connecting the ends of the plurality of pistons 220 and the scaffold 400 are included. The scaffold 400 has strength above a standard value so as to support the user's weight, but has a certain level of ductility so that it can be bent when an external force of a certain size or more (more specifically, the pressing force of the actuator 200) is applied made of material In addition, a mat 600 coupled in a detachable structure may be provided on the upper surface of the scaffold 400, and the mat 600 is applied in substantially the same way to a conventional swing plate, and the mat 600 ) A detailed description of the configuration and function of is omitted.

As described above, in the swing plate for golf practice according to the present invention, the piston 220 of the actuator 200 is not directly connected to the footrest 400, but is connected to the footrest 400 by a separate rotatable joint unit 300. The actuator 200 may be fixed to stand vertically. In this way, when the actuator 200 is erected and fixed vertically, even if the user's weight applied to the scaffold 400 is very large, the actuator 200 does not tilt or shake to one side, and thus the scaffold ( 400) has the advantage that it can be fixed very stably.

In addition, since the swing plate for golf practice according to the present invention is configured such that a plurality of actuators 200 are coupled to one scaffold 400, corners are not formed at the bent portion of the scaffold 400 like the conventional swing plate, and the scaffold 400 ) has the advantage that the whole can form a gentle curve, that is, it can implement a form very similar to the actual field ground.

On the other hand, the joint unit 300 included in the present invention is composed of a ball joint structure so that the connection angle between the piston 220 and the scaffold 400 can be changed in any direction of 360 degrees, such as front, back, left, right and diagonal directions. It has a characteristic. That is, the joint unit 300 includes a ball housing 310 having an inner space 312 with an open upper side, and a ball member inserted into the inner space 312 of the ball housing 310 in a structure capable of rotating. 320 and a stud 330 that is drawn upward from the upper surface of the ball member 320 and is coupled to the scaffold 400. At this time, since the inner space 312 of the ball housing 310 is formed in a narrow ball shape, the ball member 320 inserted into the inner space 312 of the ball housing 310 is a ball housing ( 310) is not withdrawn to the outside of the ball housing 310 unless it is damaged.

Since the ball member 320 can rotate in all directions, such as forward, backward, left, right, and diagonal directions, while being inserted into the inner space 312 of the ball housing 310, the stud 330 fixed to the ball member 320 ) is also rotatable in all directions, and the scaffold 400 integrally coupled with the stud 330 is also rotatable in all directions. That is, in the conventional swing plate, since the actuator 200 and the scaffold 400 are coupled in a hinge structure, the scaffold 400 can only rotate in one direction about the axis of rotation of the hinge, but the swing plate according to the present invention has the above As mentioned above, the scaffold 400 is connected to the actuator 200 by the joint unit 300 of the ball joint structure, so it can be tilted 360 degrees in any direction, that is, various types of ground It has the advantage of being able to implement curvature.

At this time, even if the ball member 320 rotates in the ball housing 310 so that the scaffold 400 and the stud coupled thereto tilt to one side, the ball housing 310 does not tilt or rotate to one side, The ball housing 310 is fixedly coupled to the upper end of the piston 220. For example, a fastening block 340 into which an end of the piston 220 is inserted is provided on the bottom surface of the ball housing 310, and the piston 220 drawn into the fastening block 340 is connected to the fastening block 340. It may be fixed by a fastening pin 350 fastened to pass through the fastening hole 342 formed on the side wall of the piston 220 and the through hole 222 formed on the end of the piston 220 . In addition, a fixing washer 352 may be additionally mounted on the locking pin 350 to prevent the locking pin 350 from being arbitrarily removed.

In this way, when the end of the piston 220 is coupled to be inserted into the fastening block 340, the ball housing 310 only moves up and down along the piston 220 and does not tilt or shake to one side, so that the joint unit ( 300), the scaffold 400 connected to the piston 220 via the medium can also maintain a firmly fixed state without shaking.

4 is a cross-sectional view showing the coupling structure of the joint unit 300 and the scaffold 400, and FIGS. 5 and 6 show the operation of the joint unit 300 included in the golf practice swing plate according to the present invention.

In the swing plate according to the present invention, the stud 330 is inserted into the coupling hole 410 formed in the scaffold 400 in a fitting manner so that the scaffold 400 and the stud 330 can always be inclined integrally. are combined into a structure that

At this time, when the stud 330 is coupled to the coupling hole 410 in a structure in which it is simply press-fitted, when an external force in the vertical direction is applied to the scaffold 400, the stud 330 moves through the coupling hole 410 of the scaffold 400. Since there is a risk of falling out, the swing plate according to the present invention is preferably provided with a separate coupling means 500 for fixedly coupling the stud 330 to the scaffold 400.

For example, a screw hole 332 is formed on the central axis in the longitudinal direction of the stud 330, a mounting block 334 is formed on the lower outer circumferential surface of the stud 330, and the coupling means 500 is the stud The upper washer 520 and the scaffold ( 400) and a lower washer 530 press-fitted between the upper surface of the mounting block 334.

In this way, when the coupling means 500 is composed of the coupling bolt 510, the upper washer 520, and the lower washer 530, when the manufacturer tightens the coupling bolt 510, the bolt head of the coupling bolt 510 Is pressed on the upper surface of the scaffold 400 with the upper washer 520 therebetween, and the mounting block 334 is pressed on the lower surface of the scaffold 400 with the lower washer 530 therebetween, the stud ( 330) and the ball member 320 connected thereto can be firmly coupled to the scaffold 400.

As shown in FIG. 4, when the piston 220 rises in a state where the stud 330 and the ball member 320 are coupled to the footrest 400, the footrest 400 moves the other neighboring piston 220. Depending on whether or not it is raised, it tilts counterclockwise as shown in FIG. 5 or tilts clockwise as shown in FIG. 6 . At this time, the ball member 320 rotates within the ball housing 310 according to the inclined direction of the footrest 400, but the ball housing 310 does not tilt to one side and maintains a fixed state, so that the The piston 220 coupled to the ball housing 310 can also maintain a vertically erected state. In this way, if the piston 220 of the actuator 200 is always kept vertically regardless of the inclination of the footrest 400, even if the load applied to the footrest 400 is very large, the piston 220 and the cylinder tube 210 ) is not inclined or bent to one side, it is possible to obtain an effect of remarkably improving the durability of the swing plate for golf practice according to the present invention.

On the other hand, in the present embodiment, only the bolt head and upper washer 520 of the coupling bolt 510 are shown projecting upward from the upper surface of the scaffold 400, but the bolt head and upper washer of the coupling bolt 510 If the protruding height of the 520 is high, even if the mat 600 is laid on the footrest 400, the bolt head of the coupling bolt 510 may be felt by the foot when the user stands on the mat 600. Therefore, the bolt head and the upper washer 520 of the coupling bolt 510 may be configured to be buried inside the scaffold 400.

7 to 12 are state diagrams of the swing plate for golf practice according to the present invention.

When the pistons 220 of all the actuators 200 are withdrawn together, the scaffold 400 only rises while remaining level, but when only the pistons 220 of some actuators 200 are withdrawn, the scaffold 400 is withdrawn Since only the portion connected to the piston 220 is pushed upward, the scaffold 400 is inclined to one side. In addition, since the swing plate for golf practice according to the present invention has dozens of actuators 200 coupled to one footrest 400, the footrest 400 by individually adjusting the piston 220 withdrawal distance of each actuator 200 ) can be implemented in various ways.

For example, as shown in FIG. 8, when the piston 220 of the actuator 200 located in the center is operated to increase the withdrawal distance, the scaffold 400 is curved in a convex shape, and as shown in FIG. 9, at the edge When the piston 220 of the actuator 200 is operated to extend the withdrawal distance, the scaffold 400 may be curved in a concave shape. Furthermore, when the withdrawal distance of the piston 220 is shortened and lengthened repeatedly, as shown in FIG. 10, the scaffold 400 may be curved in a sine wave shape, and as shown in FIG. 11, the scaffold ( 400) may be gently curved in a wavy shape.

In addition, since the swing plate for golf practice according to the present invention is coupled with a plurality of actuators 200 arranged horizontally and vertically on one footrest 400, each actuator 200 is independently controlled, as shown in FIG. As is done, it is also possible to irregularly form each part of the curvature pattern of the scaffold 400. That is, the swing plate for golf practice according to the present invention has the advantage of providing a very similar feeling to the actual field because the curved pattern of the footrest 400 can be implemented in a variety of ways.

13 shows a shape in which the actuator 200 is coupled to the base frame 100.

Even if the scaffold 400 is configured to be supported by a plurality of actuators 200, when some of the actuators 200 supporting the scaffold 400 are damaged at the same time, the scaffold 400 rapidly moves to one side Since it is inclined, there is a risk that the user who was on the scaffold 400 may slip and fall. Furthermore, when the plurality of actuators 200 are damaged at the same time, the scaffold 400 falls as a whole, so that a user standing on the scaffold 400 may be injured.

In the swing plate for golf practice according to the present invention, even if the actuator 200 is damaged, the footrest 400 may be configured so that it does not tilt or fall rapidly. For example, the base frame 100 is composed of a bottom frame 110 seated on the ground and a side wall frame 120 erected vertically from the edge of the bottom frame 110, and the scaffold 400 is the side wall It may be manufactured in a size capable of covering the top of the frame 120 .

In this way, when the scaffold 400 is made large enough to cover the upper end of the side wall frame 120, even if the actuator 200 is damaged and the scaffold 400 descends, the edge of the scaffold 400 is the side wall frame ( 120), the scaffold 400 does not rapidly tilt to one side or fall.

At this time, it is preferable that the height of the side wall frame 120 is appropriately selected according to the length of the actuator 200 .

On the other hand, the swing plate for golf practice according to the present invention may be configured such that the mounting position of the actuator 200 can be changed so that the footrest 400 can be bent in more various shapes. For example, the bottom frame 110 may be formed in a checkerboard pattern, and the actuator 200 may be combined in a structure capable of moving in a horizontal direction along the bottom frame 110 .

Of course, when the actuator 200 is coupled in a movable structure in this way, the coupling hole 410 to which the stud 330 of the actuator 200 is coupled needs to be additionally formed over all parts of the scaffold 400. will be.

In this way, when the actuator 200 is configured to be horizontally movable along the checkerboard-shaped floor frame 110, the arrangement pattern of the actuator 200 can be changed in a variety of ways, so that the curved shape of the scaffold 400 It has the advantage of being able to implement more diversely.

In the above, the present invention has been described in detail using preferred embodiments, but the scope of the present invention is not limited to specific embodiments, and should be interpreted according to the appended claims. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
