Description

Putting Green Angle Variable Putting Practice Device { Ground Angle Variable Putting Practice Device }

The present invention relates to a putting green angle variable putting practice device, and more particularly, when the angle of the putting green part is changed, the structure is implemented in 3 points to simplify the existing complex structure by a pair of elevating parts at the rear of the putting green part. , and a ball joint part that rotates at various angles is provided at the inner center of the putting green part, and an angle-variable putting practice putting green equipped with a breakaway prevention rail part that supports the center to prevent shaking or twisting from side to side when the angle is changed. It's about the device.

In general, since there are restrictions on distance and time for golfers to find a golf course to correct their putting posture and practice, they usually visit a golf driving range. There were many problems with time constraints, such as the time required to go to the golf driving range and the time to practice.

In addition, even in the golf driving range as described above, there are many places where the putting driving range is installed in a plane, so it is rare to have a putting driving range with an inclination like a real golf course, and even if there is an inclination, the angle of inclination cannot be adjusted, so realistic putting practice is impossible. There was a problem.

In order to reduce the burden of such cost and time, practice is performed with an indoor exercise device, and an embodiment of the exercise device will be described below with reference to the accompanying drawings.

1 is a perspective view showing an indoor golf putting practice device according to a conventional example.

A conventional golf putting practice device protrudes upward at a predetermined angle at one end of a rail to which an artificial turf 2 of a length sufficient for putting is integrally attached, and a hole cup 3 and a golf ball guide discharge path 5 are formed on the protrusion. ) is formed.

However, these conventional golf putting practice devices are capable of only simple two-dimensional practice, and since the slope of the rail is fixed, the user cannot practice at an angle other than the fixed angle.

In order to solve this problem, Republic of Korea Utility Model Registration No. 20-0322419 proposes an inclination and curvature control putting exercise machine, and the above putting exercise machine adjusts the inclination by installing height adjusting bolts and nuts at both ends of the inclination control arm. However, this is to adjust the height by rotating the nut. In order to rotate the nut, the nut and the tilt control rod must be separated, so the tilt control rod is placed on the nut, so it is not fixed during use and is not fixed even with a light load. There was a very unstable problem such as being heard at the top.

In addition, the conventional putting exerciser directly manipulates the nuts at four points to adjust the slope desired by the user, which is a problem that most users give up on operating because more effort is spent on changing the slope than the effort spent on golf practice. there was
