Putting practice device for training of keeping putter face square and controlling putting strength
View Patent ↗Disclosed is a putting practice device configured to enable training of keeping a putter face square without checking movement of a golf ball, to enable training of controlling putting strength as well as keeping the putter face square, and to enable training of practicing linear motion of a putter during execution of a putting stroke while an actual golf ball is struck. The putting practice device for the training of keeping the putter face square and controlling the putting strength includes an advance groove, a base plate, a striking part, an impact sensor, and a display part.
1. A putting practice device for training of keeping a putter face square and controlling putting strength, the putting practice device comprising:
a base plate having an advance groove formed such that a lateral side of a central part of the base plate is recessed, wherein the advance groove is configured to enable a golf ball to be mounted therein and to advance forwards therealong;
a distance display part formed on the base plate and configured to measure a distance of a backstroke along a central line of the advance groove;
a pair of striking parts mounted on the base plate such that the advance groove is interposed therebetween, wherein the pair of striking parts has a space therebetween narrower than a width of a head of a putter so that the head of the putter strikes the pair of striking parts during putting, and each of the pair of striking parts has a striking surface configured to be struck by the head of the putter and formed on the same line with each other;
an impact sensor installed on the striking surface of each of the pair of striking parts and configured to detect impact of the head of the putter striking each of the pair of striking parts; and
a display part configured to display a time point at which the impact by the head of the putter is detected, and a degree of strength applied to the impact sensor by the head of the putter.
2. The putting practice device according to claim 1 , wherein the pair of striking parts is configured to adjust the space therebetween on the base plate so that the head of the putter passes therethrough.
3. The putting practice device according to claim 2 , wherein:
one of the pair of striking parts is configured to be fixed to the base plate and the other one is configured to be moved on the base plate so as to adjust a distance to the fixing part, and
the base plate has a guide groove formed therein in a direction perpendicular to the advance groove, wherein the guide groove allows the other one of the pair of striking parts to be moved therealong.
4. The putting practice device according to claim 2 , wherein the base plate has a pair of guide grooves formed therein and configured to be symmetrical in a direction perpendicular to the advance groove, wherein each of the striking parts is moved along a corresponding one of the pair of guide grooves.
5. The putting practice device according to claim 4 , wherein the pair of striking parts is connected to each other by a space adjustment rod such that when the space adjustment rod moves, the pair of striking parts are simultaneously moved along the guide groove thereby adjusting the space between the pair of striking parts.
6. The putting practice device according to claim 1 , wherein the base plate comprises a movement prevention pad mounted in the advance groove and configured to prevent any movement of the golf ball placed in the advance groove.
7. The putting practice device according to claim 1 , wherein a plurality of the impact sensors are installed at a regular distance along the striking surface to detect an area of the head of the putter struck on the striking surfaces.
