In general, as a product developed for performing golf practice in an indoor space and a limited space, in many cases, a practice mat mainly performing golf putting practice or an indoor (golf table) made of a net is used for performing ball hitting practice in an artificial turf-shaped mat which is relatively simple to carry and store and can be easily spread and used.

In a golf game, since a lot of practice is required to stand on a lawn and drive a golf ball into a cup by putting, most golfers place putting practice apparatuses at home, office, or the like to perform putting practice.

In the putting practice process, a golf ball is placed on the mat at a putting position, and in a putting posture, the golf ball is simply put into or brought close to a hole by putting, and according to the putting practice apparatus, a user needs to pick up and collect the holes that have finished putting one by one, or an inclined surface is formed at a position spaced apart from the cup portion so that the golf ball deviated from the cup is returned along the inclined surface or brought close to the putting position.

For example, the putting practice device has a problem that when one or more golf balls are driven into the hole cup, a user needs to take out the golf balls from the hole cup one by one.

The operation of the golf ball returning device for putting practice device of the present invention having the above-mentioned construction will be described as follows.

First, as shown in fig. 1, in the golf ball returning device of the putting training aid according to the present invention, when a golfer puts a golf ball B on a ball holder 37-5 located on the same line as the upper surface of the drawing hole 13 formed on the upper surface of the case 10, the golf ball B being put rolls on the upper surface of the artificial turf part 11 and enters the hole 12 of the case 10, the first detection sensor S1 located inside detects the falling of the golf ball.

Based on the drop detection signal of the golf ball B, the first drive motor M1 operates the conveyor belt C constituting the transfer unit 20, and the second drive motor M2 operates the supply unit 30.

As described above, the dropped golf balls B are transferred to the inside of the ball guides 31 constituting the supply unit 30 by the conveyor C.

At the same time, the ball holder 37-5 located in the drawing hole is lowered. The ball holder 37-5 is lowered in association with the elevating plate 35, and when the second driving motor M2 rotates in the forward direction, the elevating plate 35 winds the wire W connected to the elevating plate 35 around the spool 39 on the rotating shaft 38, and in this case, the elevating plate 35 is pulled downward through the wire W of the wire roll R by the winding of the wire W (see fig. 6 and 7).

The lifting plate 35 is lowered by the first vertical guide rod 32 and the second vertical guide rod 33 penetrating therethrough as described above, and the first compression spring 36 on the first vertical guide rod side is compressed and lowered to the lower portion of the opening portion 31c of the ball guide 31, and the pad portion 35-2 of the lifting plate 35 is vertically guided to be lowered inside the ball guide 31, and in this case, the support portion 35-3 of the lifting plate 35 is guided by the vertical guide groove portion 31b of the ball guide 31, in which the guide hole 35f of the lifting plate 35 penetrates the ball guide 31 without interference.

On the other hand, the golf ball B transferred by the conveyor C is put on the upper portion of the ball support 37-5 formed of an artificial turf on the upper portion thereof by passing through the opening 31C along the ball catching portion 31d of the ball guide 31 and entering the inside thereof.

As described above, the ball holder 37-5 is lowered by the weight of the golf ball B placed on the upper portion of the ball holder 37-5, and the pair of lower guide shafts 37-1 are lowered by a distance corresponding to the weight of the golf ball B through the shaft hole 35d on the pad portion 35-2 side of the lifting plate 35, so that the pad plate is lowered together with the lowering of the guide shafts, thereby applying a pressure to the second compression spring 37-4 provided on the stopper portion 37-3.

As described above, when the lower detection block 37c contacts the second detection sensor S2 provided in the pad part 35-2 of the lifting plate 35 to generate a detection signal, the ball support 37-5 descends according to the operation of the ball lifting part 37 to reversely drive the second driving motor M2.

The second driving motor M2 is driven in reverse to unwind the wire W through the spool 39, and the elevating plate 35, together with the ball elevating unit 37, raises the ball holder 37-5 to the position of the withdrawal hole 13 of the box body 10, thereby putting the next pusher ready state.

As described above, in a state where the preparation of the golf ball B for putting is completed, the detection block 37c is kept in contact with the second detection sensor S2, and when the golf ball B is put on the ball holder 37-5 and the golf ball B is moved away from the position, the stopper 37-3 constituting the ball elevating unit 37 is lowered by the restoration of the second pressure spring 37-4, and the second detection sensor S2 is spaced from the detection block 37c to interrupt the detection signal, so that the second drive motor M2 is kept in a stationary state (see fig. 5).

As described above, since putting practice of golf is repeated and golf is repeatedly returned when a golf ball is driven into a hole as described above, putting practice can be performed, and golf can be quickly returned as compared with a conventional supply unit that performs a screw type elevating operation, thereby enjoying effective putting practice.

As described above, in the present invention, specific matters such as specific structural elements and the like, and the embodiments and the drawings defined therein are explained, but this is provided only for further comprehensive understanding of the present invention, and the present invention is not limited to the above embodiments, and various modifications and variations can be made from the descriptions by those skilled in the art to which the present invention pertains.
