Hereinafter, the present invention will be described in detail with reference to the drawings.

According to one aspect of the present invention, the operation of a rod-shaped elastic member 100 that is bent and deformed by an external force and returns to its original state by elasticity, an operating portion 200 that gives a bending moment to the elastic member 100, and an operation of the operating portion 200. A putting practice machine 10 is provided that includes a switching switch 300, a power supply unit 400 that supplies power to the operating unit 200 by switching the switch 300, and a rail unit 500 that forms a reciprocating path for the ball.

Referring to FIG. 1, the putting training aircraft 10 includes a rod-shaped elastic member 100, an operating portion 200, a switch 300, a power supply portion 400, and a rail portion 500.

The putting practice machine 10 is a device that assists the practice of golf putting indoors, and includes an area corresponding to a hole cup and a rail.

When the ball enters the area corresponding to the hole cup, the putting practice machine 10 can return the ball to the user's position by the rod-shaped elastic member 100.

The putting practice machine 10 has a simple structure so as to realize user convenience and economy and suppress failures, and can maintain a constant return path of the ball.

The elastic member 100 may have a rod-like shape in which one end is supported by the fixing portion 600, the elastic member 100 is bent and deformed by an external force, and then returns to the original position.

The rod type means an elongated shape, and includes a flat and long shape, a cylinder, a straight hexahedron, and the like.

The elastic member 100 may be a metal material such as a spring including a leaf spring, and various materials such as a synthetic material and carbon fiber can be used as long as it has an elastic restoring force.

Referring to FIG. 2, the elastic member 100 supported by the fixing portion 600 can hit the ball by the elastic force that is bent by the external force and then returned to the original position, whereby the ball enters the hole cup area. It is folded back in the direction.

The operating portion 200 gives a bending moment to the elastic member 100. The operating portion 200 applies an external force to the elastic member 100 to warp the elastic member 100. Then, by removing the external force, a restoring force (elastic force) is generated in the elastic member 100. The operating portion 200 is not particularly limited in its form or the like as long as it can give a bending moment by bending the elastic member 100.

According to one aspect of the present invention, the actuating portion 200 may include a crankshaft and a crankarm, and may have a rotating means for applying a rotational force to the crankshaft.

Generally, the rotating means is an electric motor that rotates by being supplied with electric energy, but there is no particular limitation on the type as long as a rotational force can be applied.

By rotating the crank shuff around the shaft, the crank arm protruding in one direction from the crank shaft can also rotate.

With reference to FIG. 2, the crank arm can apply a bending moment to the elastic member through rotational motion.

In one embodiment, the crank arm contacts the elastic member 100 by rotating counterclockwise ((a) in FIG. 2), and further rotates to warp the elastic member 100 ((a) in FIG. 2). b)) When the predetermined threshold is exceeded, the bending moment applied to the elastic member 100 is removed, and the ball is repelled by returning to the original position due to the elastic force ((c) in FIG. 2).

Here, the length of the crank arm may be variable. Since the crank arm can be changed, the bending moment given to the elastic member 100 can be adjusted.

That is, if the length of the crank arm is increased, the maximum bending moment applied to the elastic member 100 due to the rotation of the crankshaft increases, while if the length of the crank arm is decreased, the maximum bending moment applied to the elastic member 100 decreases. Therefore, a suitable restoring force can be realized by changing the length of the crank arm.

The switch 300 can switch the operation of the operating unit 200. This allows the ball to return to its original position.

The switch 300 is a switch of an electric circuit and is switched mechanically or electrostatically. That is, the switch 300 may be mechanically switched depending on the weight of the ball, or may be switched due to an electrostatic change accompanying contact with the ball, but it is sufficient if the switch 300 can be switched by contacting the ball. There are no particular restrictions on the method.

Here, the switch 300 is provided on the bottom surface of the reciprocating path of the ball and is switched by contact with the ball.

With reference to FIGS. 3 and 4, the switch 300 is provided on the rail, and the ball travels on the rail and comes into contact with the switch 300 by the user's putting. When the ball comes into contact with the switch 300, switching is performed, and the power supply unit 400 supplies electric power to the operating unit 200 by the switching.

The operating unit 200 is required to have power to give a bending moment to the elastic member 100, and the power supply unit 400 supplies electric power to operate the operating unit 200. The power supply unit 400 may be any means as long as it can store or supply electric power for driving the operating unit 200 or the putting training aircraft 10, and is not particularly limited. For example, it may be a battery or a power supply.

The rail portion 500 forms a reciprocating path for the ball. The rail portion provides a path through which the ball passes by the user's putting, and the material and shape thereof are not particularly limited. Specifically, for example, in order to bring about the effect of putting on the lawn, artificial turf or the like It may be a mat type made of carpet.

The rail portion 500 may have a semicircular recess (not shown) in which the switch 300 is provided in the central portion. Since the recess is semi-circular and dented, the put ball can enter the recess and stop. As described above, since the recess provides an area where the ball can stop and come into contact with the switch 300, the recess may be provided at an appropriate position for the ball to collide with the elastic member 100.

Further, the rail portion 500 has a wedge shape along the reciprocating path of the ball, and the switch 300 can be located on the bottom surface of the reciprocating path of the ball.

Since the ball advances on the rail portion 500, finally contacts the switch 300, and stops, the rail portion 500 may be manufactured so that the ball can be accurately stopped at a predetermined position.

Therefore, the rail portion 500 is inclined toward the downstream (about 1 to 10 °) and has a wedge shape in which the width gradually narrows in the direction in which the ball advances, so that the ball reliably contacts the switch 300 during putting. The structure is achieved.

That is, the rail portion 500 has a structure in which the height of the bottom surface gradually decreases and the width gradually decreases in the direction in which the ball advances, so that the ball traveling on the rail reliably presses the switch 300 located on the bottom surface. Can be switched.

In the above-mentioned putting practice machine 10, the switch 300 is switched by the put ball, and the ball can be returned by the elastic restoring force of the elastic member 100 which is bent and deformed.

In the above-described embodiment, the operating portion 200 has been described by a rotation method having a crankshaft and a crank arm, but in another example, the operating portion 200 has a form like a lever that reciprocates in a linear direction. Is also good.

Referring to FIG. 5, the operating portion 200 is a lever type in which a step is formed, and when the lever moves inward, a bending moment is given to the elastic member 100, and when the bending moment exceeds a predetermined threshold value, the elastic member 200 is formed. Restoring force can be applied to 100.

The elastic member 100 may be deformed by an external force and then returned to its original shape. Specifically, the materials of the elastic member 100 are metal, plastic, fiber reinforced plastics, and hard rubber (hard rubber). One or more can be selected from the group consisting of hard rubber), but the present invention is not limited to this.

The putting training machine 10 can further include a cushioning member provided on the surface of the elastic member 100. The elastic member 100 may generate noise due to collision with the ball, and a cushioning material can be attached to the surface of the elastic member 100 in order to suppress the noise.

The cushioning member is made of a soft material and is not particularly limited as long as it can absorb the impact generated by the collision with the ball. For example, soft plastic, natural rubber, styrene butadiene rubber, chloroprene rubber, nitrile butadiene rubber, ethylene propylene diene It may be rubber, butadiene rubber, or the like.
