Abstract

According to the present invention, since the golf ball is automatically supplied to the tee position and the ball hit automatically returns to the original position, it can be practiced by focusing only on hitting a swing that sends the ball at a relatively long distance, such as a driver shot or an iron shot, and can be conveniently repeated. A portable golf exerciser, in particular, was conventionally configured to allow a ball to enter and exit a casing so that the pusher releases the ball entering the casing and is received by the ball holder and supplied to the tee position, but the ball holder grips the ball directly from the outside of the casing. The present invention relates to a portable golf exerciser configured to simplify the structure and operation, and to minimize the occurrence of failure due to malfunction and overload.

The present invention relates to a portable golf exerciser that can conveniently practice the swing to send the ball to a distance.

Golf practicers currently widely used include putting exercisers and swing practice nets. However, the putter exerciser was practicing the hole-in-the-hole hole by hitting the ball from one side to the ball, so that he couldn't practice a long shot such as a driver shot or an iron shot.

Swing practice nets, on the other hand, were designed to practice long shots, so you could practice driver shots or iron shots.

However, because the distance between the tee position and the net is so close, <1> the direction of the ball, the distance, and whether a slice or a hook has occurred cannot be accurately determined. Therefore, it is difficult to determine the force output or swing posture required to send the ball to the desired position. <2> Since the ball flew from the tee position to the net and fell down and gathered in front of the net, it was difficult to collect the hit ball separately each time. <3> The minimum range of the force of the net Since it has to form a large volume basically had a problem that is difficult to transport and storage.

In order to solve the problems of the existing golf exerciser as described above, the ball tee with the application number 20-2004-0023376 'portable golf exerciser' (hereinafter referred to as a prior art) filed by the present applicant as 2004.08.16 It can be automatically supplied to the position to practice the swing while focusing only on the hit, the ball is automatically returned quickly can be conveniently repeated practice.

Here, the ball is supplied so that when the pusher is operated, the ball is discharged to the outside of the casing through the ball entrance, and when the discharged ball is received by the ball holder from the lower side of the ball entrance and seated on the ball holder, the arm installed with the ball holder is unfolded. The arms are actuated, in which order the ball holder is actuated to release the bearing of the ball.

And the return of the ball is made possible by operating the reel drive so that the line is wound on the reel unit to enter the ball connected to the tip of the line into the casing, where the reel unit is a certain distance for the ball to enter the inside of the casing Since the deceleration means have been operated since the rotation speed is reduced.

However, the above-described prior art requires improvement of the following points.

1. Looking at the operation of the arm, it is fully extended so that when the ball is fed into the tee position, it is folded about two thirds immediately, and then when the ball is returned, it is only fully folded at that time. I.e. about 2/3 folded ?? It was folded in two stages, such as 'full folding', and the operation was complicated and needed to be simplified.

The problem is that if you put the ball in the tee position and do not operate it to fold the arm and leave it as it is, the arm will collide with the club when hitting the ball. However, when the ball holder is located below the ball entrance when the ball holder is formed in an annular shape so that the ball holding is formed in the shape of holding the lower side of the ball, when the ball holder is located below the ball entrance, the line is connected to the finger This is caused by the inability to fully fold the arm because it is entangled or the golf ball is pinched by a finger, making it inoperable afterwards.

2. Looking at the ball supply process, as described above, the discharge ?? holding ?? It is in order of transfer. That is, the ball must be discharged to the outside of the casing to hold the ball by the ball holder, so a pusher is necessary for this purpose, and the pusher is required to bear various problems (complexity of structure and operation, increase in manufacturing cost, etc.). should.

In addition, when looking at the pusher, the ball is compressed into the ball entering the inside of the casing, and then returned to the elastic force of the spring is configured to discharge the ball to the outside of the casing, when the elastic force of the spring is set to be larger than the reference value discharged There is a high possibility of malfunction due to the nature of the spring, such that the ball is excessively over the ball holder, the ball holder is not able to receive the ball, and conversely, the ball is not discharged from the casing if it is set to be small or naturally weakened by prolonged use.

3. The reel unit consists of a reel body, spool, rotor, power transmission device, lever, veil, line roller, lever motor, etc., the spool moves back and forth with respect to the reel body, and the rotor rotates with respect to the reel body. Since the rotation and the reciprocating movement of the spool by the separate operation is implemented at the same time, the structure is complicated and unnecessary operation was a lot when viewed as a whole, it was required to prepare measures in relation to this.

In addition, the lever is composed of a pair, and both ends of the bale are connected to each end thereof, and a lever motor for operating the lever is also provided with a pair of mechanisms to operate by simultaneously applying power to both sides of the bale. It was inefficient to use two motors each, and the operating stability was inferior, such as the bale twisting in case of mismatched lever motor operation.

4. The deceleration means of the prior art consists of a metal ball attached to a line, a metal bend and a metal plate provided on a line roller, a control unit, and the like. At this time, the metal band and the metal plate are positioned to face each other, and when the metal ball passes through it, it is connected via this metal ball, and when so connected, it outputs a signal instructing the control unit to control the operation of the reel drive. do.

Therefore, when foreign matter having an insulating property on the surface of the metal ball, even if the metal ball passes between the metal band and the metal plate, the connection is not made there is a lot of possibility that the malfunction may be caused. Of course, this malfunction caused damage to the casing or the pusher.

On the other hand, the metal ball is made of metal, but the lines are different from each other due to their characteristics, such as fibers, not metal. Therefore, it is not easy to fix the metal ball to the line. There was also a problem that the position of the ball changes frequently.

This also caused the line to be broken, discarding the part after it was broken and reconnecting the golf ball to the tip of the rest of the line, even if the metal ball was placed on the discarding line.

The present invention has been made to solve the problems of the prior art, by forming the size of the hole (ball entrance) for entering the ball into the casing smaller than the ball does not enter the inside of the casing when returning the ball. The ball holder is not in close contact with the hole, and the ball holder is configured such that the holding is formed in the form of holding both sides from the upper side of the ball, and the returning ball is placed in front of the hole so that the ball enters the ball holder and is naturally gripped. Portable golf exerciser that can supply the ball to the tee position by holding the ball and operate the arm to be folded at a time because the ball or line does not interfere with the ball holder even when the ball is returned while the arm is folded. The purpose is to provide.

Another object of the present invention is that the spool of the reel unit can be directly installed on the shaft, and when installed, it is possible to achieve the operation of the spool spontaneously without a rotor, unlike the prior art by rotating and reciprocating at the same time. The present invention provides a portable golf exerciser having a lever and connecting only one end of the bale to the end thereof to simplify the structure and improve operational stability.

Still another object of the present invention is to decelerate from the method of outputting a signal to the control unit when directly connected via an actuator (metal ball) in the deceleration means, and configured to output a signal when pressed and operated by the action of the actuator. It is thereby to provide a portable golf exerciser that can prevent the malfunction even if foreign matters on the surface of the actuator.

Another object of the present invention is to configure the actuator to be formed at any time by the user directly on the line can easily achieve a fixed invariance of the position as well as a portable golf that can be easily formed when the line is broken and the golf ball again To provide a exerciser.

Meanwhile, the present invention is not shown in the drawings, but as in the prior art, when the floor of the practice place is poor, the swing mat used here can be further configured to measure the distance of the batting ball and notify the user of the distance. .

Looking at the operation of the present invention configured as described above are as follows.

First, the veil 126 is usually erected so as to surround the upper side of the spool body 123, the line 5 is wound around the spool body 123, and the golf ball 1 is closely attached to the hole 111. 150 is folded to maintain the ball holder 160 gripping the golf ball (1).

When power is supplied in such a state, the reel operation sensor 134 indicates that the reel driving device 140 is in a stopped state, and the golf ball position sensor 146 indicates that infrared rays that are radiated are blocked by the golf ball 1. The respective sensing signals are output to the control unit 200, and the control unit 200 outputs the corresponding control signals to operate the lever motor 129 and the arm motor 171.

Therefore, in accordance with the operation of the lever motor 129, the drive pulley 132d installed on the motor shaft is rotated, and the rotational force of the drive pulley 132d is transmitted to the driven pulley 132p via the belt 133 to drive the driven pulley. The shaft 131 provided with the pulley 132p and the lever 125 provided in the shaft 131 are rotated. At this time, the bale 126 connected to the lever 125 is laid down and rotated to surround the front of the spool body 123.

When the next lever 125 is rotated by an angle, the operation protrusion 136, which rotates together with one of the pulleys 132d and 132p, operates the limit switch 137 of the lever operation sensor 135. The switch 137 outputs the detection signal to the control unit 200, and the control unit 200 outputs the control signal to stop the lever motor 129. At this time, the veil 126 is maintained in a lying state.

On the other hand, in accordance with the operation of the arm motor 171, the rotating body 176 installed on the motor shaft is rotated, the rotational force of the rotating body 176 is the drive gear of the arm transmission means 172 via the friction clutch 177. The driven gear 174, which is transmitted to 175 and engaged with the drive gear 175, is rotated about the driven shaft 173. At this time, the first rod 151 installed to rotate together with the drive gear 175 on the driven shaft 173 is rotated to unfold.

Next, when the first rod 151 is fully unfolded, the operating table 179 rotating together with the rotating body 176 operates the limit switch 180 of the arm operation sensor 178, which is the limit switch 180 ) Outputs the corresponding detection signal to the control unit 200, and the control unit 200 outputs the corresponding control signal to operate the arm motor 171 in reverse.

As described above, the arm manipulation wire 182 of the rod manipulation mechanism 181 is tensioned in tension while the first rod 151 is unfolded, so that the tension spring 184 is tensioned and the arm manipulation wire 182 is stretched. The arm operating wire 182 is released from tension by rotating the operating table 179 connected to one end of the arm closer to the tension pin 183 for the female operating wire, thereby restoring the tension spring 184 to its original shape. While pulling the outside of the second rod 152. At this time, the second rod 152 is rotated to unfold.

In addition, the pin manipulation wire 165 of the pin manipulation mechanism 164 is rotated so that the connection with the rotating body 176 is away from the tension pin 166 for the pin manipulation wire and the action of the tension pin 166 for the pin manipulation wire. Tension is tensioned and pulls the movable pin 163 of the ball holder 160 by the pulling operation in this tensioning process.

Therefore, when the movable pin 163 is inserted, the state in which the fixing pin 162 and the movable pin 163 grasp the golf ball 1 is released, and the golf ball 1 falls.

Then, when the first rod 151 is completely folded by the operation of the arm motor 171, the operating table 179 operates the limit switch 180 on the opposite side of the arm operation sensor 178, according to the control unit ( The arm motor 171 is stopped by the control operation of the 200.

In the process of folding the first rod 151 as described above, the arm manipulation wire 182 of the rod manipulation mechanism 181 is rotated so that the manipulation table 179 moves away from the tension pin 183 for the arm manipulation wire. It is tensioned tightly and pulls the inside of the second rod 152 by the pulling operation in this process. At this time, the second rod 152 is rotated to be folded, thereby the tension spring 184 is tensioned.

In addition, the pin operation wire 165 of the pin operation mechanism 164 is released from tension by being rotated to be close by being rotated so that the connection with the rotating body 176 is close to the tension pin 166 for the pin operation wire, The compression spring 167 is pushed to the movable pin 163 while being restored to the original. At this time, the movable pin 163 protrudes.

As described above, the ball holder 160 is operated so that the bale 126 is rotated to lie down and the arm 150 is unfolded and thus the golf ball 1 falls when the arm 150 is unfolded.

Then, the golf ball 1 is blown away, and the line 5 connected to the golf ball 1 is released from the spool body 123.

After the golf ball 1 is completely stopped, the return button 145 is operated.

Then, the reel motor 141 is operated, the reel operation sensor 134 detects this and outputs a corresponding detection signal, and according to the signal, the control unit 200 outputs a control signal to reverse the lever motor 129. To work. At this time, the veil 126 is erected and rotated to surround the upper side of the spool body 123.

Next, when the lever 125 is rotated by a predetermined angle by the operation of the lever motor 129, the operation protrusion 136 operates the limit switch 137 opposite to the lever operation sensor 135, and thus the control unit 200. ), The lever motor 129 is stopped. At this time, the veil 126 is maintained in a standing state.

On the other hand, as the reel motor 141 operates, the drive gear 144 of the reel transmission means 142 installed on the motor shaft rotates, and the driven gear 143 meshed with the drive gear 144 rotates. The hollow shaft 124 provided with 143 is rotated about the worm shaft 121, and the hollow shaft 124 is rotated together with the spool body 123 installed at the outer circumference thereof and at the same time, the guide pin 124p. ) Is moved back and forth according to the guide of the guide groove (121g) of the worm shaft 121 is fitted. At this time, the line 5 is guided to the spool body 123 on the roller 127 by the bale 126 and the line roller 127, and is evenly wound over the entire spool body 123.

In the process of winding the line 5 to the spool body 123 as described above, if the extension 148 provided in the line 5 is in contact with the extension position detector 149, the extension 148 is an extension part. The position sensor 149 is pressed and operated, and the extended position sensor 149 outputs a detection signal to the control unit 200, and the control unit 200 outputs a control signal to adjust the rotational speed of the reel motor 141. Decrease. At this time, the line 5 is gradually wound on the spool body 123.

After the line 5 is completely wound on the spool body 123 and the golf ball 1 is in close contact with the hole 111, the golf ball position detector 146 detects this and outputs a corresponding detection signal. Accordingly, the control unit 200 outputs a control signal to stop the reel motor 141. At this time, the golf ball 1 is sandwiched between the fixing pin 162 and the movable pin 163 is gripped.

The subsequent operation is then performed by repeating the series of steps described above.

For reference, when the line 150 is stretched when the arm 150 is unfolded, it may not be smoothly released from the spool body 123. Therefore, it is preferable that the reel motor 141 is rotated about two to three times before operating the arm 150 to be unfolded so that the line 5 is released from the spool body 123.

In addition, the returned golf ball 1 may collide with the hole 111 and bounce off without being held by the ball holder 160, which further reduces the rotational speed of the reel motor 141 or the golf ball 1 The reel motor 141 may be rotated about two or three times immediately after being bounced, so that the line 5 may be wound around the spool body 123.

The present invention constructed and acting as described above can supply the ball to the tee position without a pusher because the ball is held in the ball holder while being held in close contact with the hole of the casing when the ball is returned to its original position. Since the holder grips both sides from the top of the ball, even if the arm is folded when the ball is returned, the ball or line does not interfere with the ball holder so that the ball can be fed to the tee position and the arm can be folded at once. The advantage is a simple supply chain and simple operation.

In addition, a worm shaft is provided, and the spool is installed on the worm shaft so as to be directly rotatable.
