Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a putter training machine. More specifically, the present invention relates to a putter practice machine that can practice putting with a putter by changing the slope of a portion near the hole or by keeping the slope of the portion constant.

There is no conventional putter practice machine that can change the slope of the area near the hole, and it is only possible to practice with the area near the hole sloped artificially, and it is even more difficult to change the slope. It was hot.

Currently, most of the greens near the holes at Japanese golf courses are sloped, and practicing with conventional putting practice mats that cannot change the slope is insufficient for actual golf practice. A putting training machine with a variety of inclinations is necessary for practice in line with actual combat.

The putter practice machine of the present invention is capable of mechanically changing the slope of the area near the hole each time a golf ball enters the hole, or allowing practice of putting with a putter while keeping a certain slope constant. It is.

The putter training machine of the present invention lifts and lowers a deck having a hole to which a putting mat is attached, on both sides of the deck about a line that is perpendicular and parallel to the center line of the deck in the direction in which the ball travels. The deck is supported as much as possible, and the floating platform is configured and supported in such a way that the ball receiving tray of the floating platform provided below the hole of the deck descends due to the weight of the ball and rises when the ball falls off. The lower surfaces of both sides of the deck are supported by wheels eccentrically provided in opposite directions at both ends of a shaft passing through the fulcrum of the lifting motion, and a ratchet wheel is fixed to the shaft passing through the fulcrum of the swinging platform in the swinging platform, and the ratchet Just like how you can insert and remove pawls between the teeth of a car,
A pawl is rotatably provided on the swing base, and each end of the swing base moves up and down each time a golf ball enters a hole, and as the ball goes up and down, the ratchet wheel is rotated by the pawl and fixed to the ratchet wheel. This pattern training machine is constructed so that the inclination of the deck can be changed by rotating wheels provided at both ends of a shaft.

Further, in the putter training machine of the present invention, by removing the pawl portion of the pawl fitting from the ratchet wheel, it is possible to practice putting while keeping the slope of the deck constant.

The putter training machine of the present invention will be explained with reference to the drawings.
FIG. 1 is a plan view of the training aircraft of the present invention, FIG. 2 is a side view in the longitudinal direction, and FIG. 3 is a side view in the - direction of FIG.

The putter mat 1 is a flexible mat with artificial turf on its surface. A hole 2 is drilled in the putter mat 1, and the area near the hole is pasted onto the deck 3. The lower surface of the space is supported by a plate 4, and a golf ball fall guard 5 is fixed around the deck 3.

The brackets 6 and 7 fixed to the lower surface of the deck 3 are connected to the pins 1 and 1 to the support fittings 9 and 10 fixed on the base plate 8.
1 and 12, the deck 3 is supported so that both sides thereof can be raised and lowered about a line passing through the pins 11 and 12, as shown in FIG. Said deck 3
A mechanism is provided below the deck 3 to support the deck 3 with an inclination and to change the inclination.The details of this mechanism will be explained with reference to FIGS. 4 to 7. One long shaft 15 is inserted into the swing base 14 which has a tray 13 fixed to the upper end surface for receiving the golf ball that has entered the hole, and can be rotated around the shaft 15 by a bearing fitting 16 fixed on the base plate 8. is supported by
Weights 17a and 17b are fixed to the end of the floating table 14 opposite to the fixed end of the tray 13, and when a golf ball is placed on the tray 13, the floating table 14 moves to the fixed end of the tray 13. The ball falls into the ball discharging tray 18 at the bottom and is ejected outward from the lower part of the deck 3, and the end portion rises again.
Support rod 1 fixed at the end with 7a, 17b
9 supports the ends having weights 17a, 17b and the tray 13 at a convenient height.

Both ends of the shaft 15 are supported by bearings 20, 21, crank arms 22, 23 are fixed to both ends, and wheels 24, 25 are rotatably provided on the outside of the crank arms 22, 23 by pins. . Axle 15 and wheel 2 by both crank arms
The eccentric distances between the centers of 4 and 25 are almost the same, but the eccentric directions are reversed. Therefore, when the crank on the wheel 24 side is facing downward, the crank on the wheel 25 is facing upward. At this time, the deck 3, whose lower surface is supported by the wheels 24 and 25, slopes down to the left as shown in Figure 6. When the shaft 15 turns 180 degrees, the direction of the crank arms on both sides is reversed, and the deck 3, which is supported by both wheels, descends to the left. The slope of No. 3 is also reversed, going down to the right.

A ratchet wheel 27 for rotating in one direction is fixed to the axle 15 in the swing table 14, and a pawl fitting 28 for rotating the ratchet wheel 27 is mounted between the ratchet wheel 27 and the ball receiving tray 13 in the swing table. It is rotatably attached to the pin 29 of. The upper surface of the swing table has an opening of an appropriate size so that the pawl fitting 28 can be attached to and removed from the ratchet wheel 27 in order to activate or deactivate the ratchet mechanism.

Since the putter practice machine of the present invention has a mechanism configured as described above, if the pawl of the pawl fitting 28 is applied to the ratchet wheel 27 to activate the ratchet mechanism and practice putting, the golf ball will be Enter and get on the ball tray 13,
Due to the weight of the ball, the end of the swing table 14 with the receiving tray 13 is lowered, and the tip of the pawl 28 turns the ratchet wheel by the angle of one tooth. This turns the crank arms 22, 23 at both ends by the angle of one tooth of the ratchet wheel, causing the wheels 24, 25 to rotate at the same time. By rotating the crank arms 22, 23, the vertical distance from the center of the shaft 15 to the tops of both wheels changes, and the inclination of the deck 3 changes. Pawl fitting 28
When the golf ball is removed from the ratchet wheel and laid down on the swing platform, the swing platform swings under the weight of the golf ball, but the crank arms 22 and 23 do not rotate, resulting in the deck 3 being tilted. does not change, so the same slope is maintained.

With the structure as described above, the putter practice machine of the present invention changes the slope of the area near the hole each time it enters a hole, and allows practice with a different slope.
In addition, since you can practice on the same slope, you can practice in conditions much closer to the actual golf course hole than the conventional practice with a mat without slope, and changing the slope is a simple method. Because of its structure, it is less likely to break down, and since it does not require a power source, it is economical and has excellent durability.
