It's about putting practice equipment.

Golf is a ball game sport in which a ball resting on a course is hit with a club (club) and put into a designated hole (hole), and the game is contested with the required number of strokes until then. In other words, the side that hits the fewest balls wins the game. This is because the more you hit, the more mistakes you make.

Golf is originally an outdoor sport, but practice is important to play well. For this reason, a lot of golf practice devices are used.

Golf practice devices are indoor golf devices, which are mainly divided into screen golf for practicing by displaying various terrains or environments of actual golf courses on the screen, and golf putting practice devices for putting golf balls in hole cups.

On the other hand, putting is an important part of golf as putting a golf ball on a green where a hole cup is formed by rolling a golf ball using a putter. Because of this, practicing golf putting is important.

Accordingly, recently, various types of devices for practicing putting have been released or are scheduled to be developed, but the need for a new type of golf putting practice device has emerged in that the structure is still inferior in putting practice effect.

Referring to these drawings, the large golf putting practice device 100 according to this embodiment can practice golf putting while arbitrarily adjusting the inclination through a simple but efficient structure, thereby contributing to improving golf performance .

The large golf putting practice device 100 according to the present embodiment capable of providing these effects may include a device frame 110, a putting plate 120, and a plurality of up/down driving units 130.

The device frame 110 is a part forming an external frame in the large golf putting practice device 100 according to this embodiment.

Referring to FIGS. 2 and 4, the device frame 110 includes a pair of main frames 111 that form a long axis but are spaced apart from each other and have an up/down driving unit 130 installed thereon, and a pair of main frames. (111) includes a plurality of sub-frames 112 connecting between them.

In this structure, a bracket 115 for angle adjustment is provided between the main frame 111 and the sub frame 112, that is, a portion where the main frame 111 and the sub frame 112 are connected. The bracket 115 for adjusting the angle forms a hinge structure.

The brackets 115 for angle adjustment allow natural twisting of the putting plate 120 when the up/down driving units 130 are individually driven. If the up/down drive unit 130 operates individually without the bracket 115 for angle adjustment, in the case of the up/down drive unit 130 at a low height, it does not adhere to the floor and floats in the air. condition, making it difficult to perform the function of a putting mat. Therefore, it is preferable that the bracket 115 for angle adjustment be provided between the main frame 111 and the sub frame 112, that is, a portion where the main frame 111 and the sub frame 112 are connected, as in the present embodiment.

The putting plate 120 is a structure connected to the top of the device frame 110 and provides a place for practicing golf putting.

Such a putting plate 120 has a plate body 121 having a plurality of holes 123 into which golf balls are inserted, and is disposed higher than the plate body 121 on the circumferential surface of the plate body 121 to provide golf balls. It may include a body flange 122 that prevents displacement.

The plate body 121 is a part where a person actually stands up and practices golf putting. Therefore, an environment similar to that of an actual green can be created. For example, the plate body 121 may be made by actually placing grass or the like on a plate material having excellent rigidity.

At this time, the plate body 121 applied to this embodiment forms a large area. Therefore, since the putting position may vary according to the inclination, the plurality of holes 123 may be symmetrically arranged on both sides of the plate body 121 . In the drawing, three holes 123 are symmetrically arranged on both sides of the plate body 121, but the scope of the present invention is not limited to the number thereof.

The inclination of the putting plate 120 may be arbitrarily adjusted due to the operation of the plurality of up/down driving units 130 mounted on the device frame 110 . Please elaborate on this.

For example, in FIG. 3, the large golf putting practice device 100 according to the present embodiment has four corners C1 to C4, respectively, the front first and second corners C1 and C2, the rear third and fourth corners ( Assuming C3 and C4), (a) of FIG. 3 is a state in which the first and second front corners C1 and C2 are lifted, that is, up, and (b) of FIG. 3 is a state in which the first and second front corners C1 and C2 are raised. A state in which the corner C1 and the third rear corner C3 are up, and in (c) of FIG. 3, the first front corner C1 and the fourth rear corner C4 are up. am.

To put it simply, Figure 3 (a) is a state where the front part is lifted and inclined, Figure 3 (b) is a state where the left part is lifted and inclined, and Figure 3 (c) is a front and rear corner It is in an S-shaped twisted inclined state.

Of course, although not shown in the drawing, the rear part opposite to FIG. 3 (a) is lifted and tilted, and the right part opposite to FIG. 3 (b) is lifted and tilted, and FIG. 3 (c) and The opposite front and rear corners are lifted, so it is possible to fully implement an S-shaped twisted inclined state.

As such, since the large golf putting practice device 100 according to this embodiment can implement an S-shaped twist in addition to the front, rear, left and right directions, the desired slope can be further subdivided and arbitrarily set. Therefore, it is possible to practice golf putting according to various situations in an indoor environment, thereby contributing to improving golf performance.

On the other hand, the up / down driving unit 130 is provided to be connected to the device frame 110 and the putting plate 120 in the corner (corner) area of the device frame 110 and the putting plate 120, putt at that position It serves to drive the plate 120 up/down.

In particular, the up/down drive unit 130 applied to this embodiment converts horizontal motion into vertical motion as shown in FIG. 6 to drive the putting plate 120 up/down.

For reference, in order to up/down the putting plate 120, for example, a method of connecting the putting plate 120 by erecting a cylinder may be considered. However, when up/down of the putting plate 120 is implemented by erecting the cylinder, that is, vertically, the overall height of the equipment is inevitably increased.

However, in the case of this embodiment, since the up/down drive unit 130 converts horizontal motion into vertical motion and drives the putting plate 120 up/down as shown in FIG. 6, the overall height of the product is applied. can be lowered, which can contribute to the implementation of compact equipment.

The plate coupling head 160 is a structure coupled to the plate body 121 of the putting plate 120 . The plate coupling head 160 may be coupled to the plate body 121 of the putting plate 120 through screw coupling.

The rod connecting rod 165 is a structure in which one side is connected to the actuator rod 152 of the linear actuator 150 and the other side is connected to the plate coupling head 160 to be relatively rotatable. Due to the operation of the actuator rod 152, the rod connecting rod 165 may move forward and backward.

At this time, the head rotation shaft portion 161 is provided on the rod connecting rod 165 and the plate coupling head 160 . The head rotation shaft portion 161 is also applied in a hinge structure like the body rotation shaft portion 145, is connected to the rod connector 165 and the plate coupling head 160, and serves to allow rotation of the plate coupling head 160 . When the putting plate 120 is tilted as shown in FIGS. 3, 7 to 9 by providing the head rotating shaft 161, the rod connecting rod 165 or the plate coupling head 160 is not damaged.

The motion transmitting unit 170 is coupled to the actuator supporting plate 142 and the rod connecting rod 165, and is a means for transmitting the linear motion of the actuator rod 152 to the rotational motion of the rod connecting rod 165.

The motion transmission unit 170 is connected to the rod connecting rod 165 and the long hole 143 of the actuator supporting plate 142, and when the actuator rod 152 operates, the rod connecting rod 165 moves along the trajectory of the long hole 143. It may include a linear guide unit 171 for moving and a link member 172 having both ends connected to the actuator supporting plate 142 and the rod connecting table 165 to be relatively rotatable.

By this configuration, when the actuator rod 152 advances by the action of the linear actuator 150, for example, as shown in (a) to (b) of FIG. 6, the linear guide part 171 moves on the trajectory of the long hole 143, The connecting rod 165 is pressed, and at the same time, as the link member 172 operates, the rod connecting rod 165 can be erected. Therefore, the corresponding position of the putting plate 120 connected to the plate coupling head 160 provided at the end of the rod connecting rod 165 can operate up as shown in FIGS. 8 and 9, and as a result, as shown in FIG. An inclined motion of the putting plate 120 may be implemented.
