Description

Device for golf ball retrieving}

The present invention relates to a golf ball collection device, in which the overall length of the collection part is variable by an extension pusher that rotates around a central pusher, so that golf balls can be collected by remote control in narrow and wide spaces. It is about a golf ball collection device.

Generally, in the case of an indoor golf course, the ball hit by the golfer is caught on a barrier or net located nearby and is automatically collected back to the position where the batter is standing, so there is no need to collect the ball separately, but in the case of an outdoor golf driving range, the ball is automatically collected in the actual field. A large net is installed at a location several hundred meters in front of the practice field to suit the distance and environment of exercise, so the ball hit by the practitioner flies a certain distance, gets caught in the net and falls to the floor, then gathers in one place and returns to the batting box where the practitioner stands. It is configured to be supplied automatically.

This type of outdoor golf driving range is equipped with a net of a certain height surrounding a certain area in front and on the sides of the driving range, and the floor consists of a flat surface near where the batter stands and a slope at a distance, and at the bottom of the slope is a drop down slope. There is a ball collection groove that automatically rolls down the ball and collects it in one place, then automatically collects it in the batter's box where the batter is standing.

However, if the golf ball hit by the batter flies a long distance, the golf ball is recovered by a net installed at an angle. However, in approach practice, that is, the ball that falls on the flat ground near the batter's box where the batter is standing is practiced for a certain period of time and many people use it. The golf ball remains.

In this way, in order to collect golf balls remaining on the flat ground nearby, a number of people go up to the flat area of the practice range during breaks and push balls that have fallen on the flat ground into the ball collection groove to collect the golf balls.

However, when a person goes in and retrieves a golf ball, golf driving range users inevitably have to stop practicing and take a break for the safety of the person collecting the golf ball, which only results in the user's hitting flow being cut off. In addition, since golf balls had to be collected frequently, a lot of time was wasted, and there were various problems such as the need for adequate manpower to be prepared at all times to collect balls.

Public Patent Publication No. 10-2009-0112338 (2009.10.28) Registered Utility Model Gazette registration number 20-0397936 (2005.09.30) Registered Patent Publication No. 10-1761171 (2017.07.19) Registered Patent Publication No. 10-1207283 (2012.11.27)

The present invention collects golf balls remaining in the golf driving range field by remote control, preventing safety accidents due to manpower input, and reducing the cost of purchasing golf balls for golf practice and recovering golf balls. This has the effect of reducing labor costs.

The present invention enables continuous recovery of golf balls without stopping the user's practice, which not only improves the user's practice concentration, but also prevents the hitting rhythm from being interrupted, thereby improving the user's practice efficiency.

In the present invention, the extension push bar is spread around the central push bar to extend the entire length of the push bar, thereby improving the collection efficiency for golf balls remaining on the flat area that serves as a flat field formed in front of the batter at outdoor golf driving ranges, etc. There is an effect.

The present invention has the effect of improving the mobility of the main body and the collection efficiency of golf balls by allowing the overall length of the push bar to be varied as needed by the central push bar and the extended push bar.

The present invention has the effect of allowing the golf ball collection operation to be smoothly performed not only on flat ground but also on a mixture of flat ground and inclined surfaces, as the extended push rod is rotated and moved around the hinge axis by the push drive eastern part.

The present invention is provided with a pair of independently driven running units, so that not only can the running direction and direction change be freely performed, but rotation and direction change are also possible within a narrow radius, thereby providing protection against golf balls remaining in narrow spaces or corners of the ground. This has the effect of making recovery easy.

In the present invention, the collection part is pressed in the direction of the ground by the elastic force of the support part, thereby preventing the collection part from lifting against the ground, and this has the effect of stabilizing the running of the main body and the collection of golf balls.

In addition, the present invention allows the collection unit to be cushioned and flowed in the vertical direction by the support part, so that the impact generated on the collection unit due to ground conditions or obstacles is alleviated, thereby preventing damage to the collection unit and preventing the main body from running. This has many benefits, including stabilization.
