BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to golf ball carrying apparatuses used at driving ranges and, more particularly, to a golf ball carrying apparatus which is used to carry golf balls, which have been moved to each floor by a ball carrying elevator, to swing compartments in a single-floor or multi-floor driving range in which the golf balls that have been struck by golfers are collected in a machine room.

Generally, in a driving range, golf balls, which have been collected in a machine room, are distributed to floors by a conveyor. As shown inFIG. 1, the distributed golf balls are moved to swing compartments by a carrying means, which is provided in a ceiling or a floor of the driving range. Thereafter, each golf ball is set to a desired position by a tee-up device provided in each swing compartment.

A representative example of such a carrying means was proposed in Korean Patent Registration No. 473656, which was filed by the inventor of the present invention, and is entitled “APPARATUS FOR CARRYING GOLF BALL USED IN DRIVING RANGE”.

In the carrying apparatus of No. 473656, a ball supply channel is divided into first, second and third channels, and possibly more. Inclined guide plates are provided in the respective channels, and belts, each of which is reciprocally moved by a motor, are provided above the respective guide plates, to carry golf balls through supply passages provided in the walls of the respective channels.

However, the conventional carrying apparatus has a problem in that there are spatial restrictions limiting the installation thereof with respect to driving ranges having various shapes.

For example, in the case where a driving range is constructed using glass or another transparent material for parts other than the floor of the driving range, the carrying apparatus must be embedded in the floor, because there is a problem in that the driving range has a poor appearance if the carrying apparatus is provided on the ceiling. In this case, it is not easy to maintain and repair the carrying apparatus. Also, to facilitate the work of maintaining or repairing the carrying apparatus, part of a mat (an artificial grass mat or the like) which corresponds to the carrying apparatus must be cut and removably installed. Therefore, there are problems in that this part of the mat may undesirably move, which worsens the external appearance of the driving range.

BRIEF SUMMARY OF THE INVENTION

Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a golf ball carrying apparatus which is used in a driving range to supply golf balls, which have been carried to floors using an elevator and to a swing compartment. The apparatus has a simple structure, such that the space required to carry the golf balls is minimized. Maintenance and repair work thereon can be easily conducted, so that it is not required to remove or removably install parts of a mat between the swing compartments when maintenance or repair work is desired. The driving range has a clean and superior external appearance, and repair and installation costs are reduced. Extra golf balls can always be provided to every swing compartment.

In order to accomplish the above object, the present invention provides a golf ball carrying apparatus used at a driving range. A chain is connected between a drive unit having a motor and a driven unit spaced apart from the drive unit by a predetermined distance, so that the chain is reversibly rotated. A guide rail is provided around the chain and having a shape reduced in width from a top thereof to a bottom thereof, so that golf balls are placed in and guided by the guide rail, with a plurality of ball supply ports and holes formed in the guide rail in a longitudinal direction, and a first detecting sensor provided on an end of the guide rail. A connection guide is coupled to an end of each of the ball supply ports to guide a golf ball, unloaded from the guide rail, to a carrying pipe, the connection guide being provided in each of a plurality of tee-up devices, with a second detecting sensor provided at a predetermined position in the connection guide. A pushing means is provided at a position corresponding to each of the connection guides, comprising a movable part to be retractably inserted into the associated hole of the guide rail.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, a golf ball carrying apparatus used at a driving range according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

FIG. 2is a perspective view showing the golf ball carrying apparatus100according to the preferred embodiment of the present invention.FIG. 3is a perspective view showing a drive unit10and a tee-up device20of the golf ball carrying apparatus100of the present invention.FIG. 4is a plan view of the tee-up device20of the golf ball carrying apparatus100of the present invention.

As shown in the drawings, in the golf ball carrying apparatus100used at the driving range (hereinafter, referred to simply as a carrying apparatus) according to the preferred embodiment of the present invention, golf balls, which have been carried by an elevator (not shown) to floors in the driving range, are supplied into drive units10. Thereafter, the golf balls, which have been supplied into each drive unit10, are supplied onto a guide rail12, in which the chain11is installed, and are subsequently carried to the tee-up device20, which is provided in each swing compartment.

Here, the chain11is installed in the corresponding floor and is reversibly rotated by the drive unit10and a driven unit13, which are provided on opposite ends of the chain11.

Furthermore, the chain11is provided in the guide rail12, which has a shape such that it is reduced in width from the top thereof to the bottom thereof. Ball supply ports12aare formed in the guide rail12at predetermined positions spaced apart from each other in a longitudinal direction. Furthermore, a hole12b, through which a part of a golf ball pushing means30is exposed, is formed in the guide rail12at a position corresponding to each ball supply port12a. A detecting sensor13ais provided on an end of the guide rail12.

In addition, one end of a connection guide14is coupled to the outer end of each ball supply port12ato guide golf balls entering the ball supply port12ainto the associated tee-up device20.

The connection guide14is bent in a U shape and serves to supply golf balls, which are supplied thereto, to a carrying pipe40without allowing golf balls to escape from the connection guide14.

The golf ball pushing means30is attached to a coupling plate31, which is coupled to the guide rail12, and is operated by a sensor14a, which is provided in the connection guide14. The golf ball pushing means30includes a pushing rod32, part of which is inserted into the guide rail12when the golf ball pushing means30is operated.

Meanwhile, the golf balls, which have been supplied into the connection guides14, are supplied into the carrying pipes40, which are connected to the respective tee-up devices20, and are thereafter stored in the carrying pipes40and carried to the tee-up devices20.

Furthermore, opposite ends of each carrying pipe40are coupled to respective support members41and41′. The support members41and41′ are installed in the associated tee-up devices20.

The end of the carrying pipe40which is supported by the support member41is coupled to and rotated by a motor42, which is provided at a predetermined position on the support member41, through a chain. In addition, a spiral protrusion43is provided on the inner surface of the carrying pipe40. Thus, the carrying pipe40moves the golf balls, which have been supplied from the connection guide14, to the associated tee-up device20.

The tee-up device20serves to move a supplied golf ball upwards to a desired position at which a golfer strikes the golf ball. This is a well known technique, therefore further explanation is deemed unnecessary.

In the drawings, the reference numeral50denotes a cover for the guide rail12.

The operation of the carrying apparatus100according to the embodiment of the present invention having the above-mentioned construction will be explained in detail with reference toFIGS. 5aand5b.

FIG. 5ais a front cross-sectional view showing a process of carrying a golf ball using the chain11of the carrying apparatus100.FIG. 5bis a front cross-sectional view showing a process of removing the golf ball from the chain11of the carrying apparatus100.

Golf balls are carried from an underground machine room to the floors by the elevator. Thereafter, the golf balls are supplied into the drive unit10of the carrying apparatus and seated on the chain11, which is provided in the carrying apparatus, in a line.

The golf balls, which have been seated on the chain11, are moved under the guidance of the guide rail12in a line. When the leading golf ball reaches the connection guide14, the sensor14adetects whether a golf ball is present in the connection guide14. If no golf ball is present in the connection guide14, power is automatically applied to the golf ball pushing means30to protrude the pushing rod32, so that the direction in which the golf ball is moved is changed. Thus, the golf ball is removed from the guide rail12and supplied into the connection guide14through the ball supply port12a. Thereafter, the golf ball is supplied from the connection guide14into the carrying pipe40.

At this time, the motor42, which is provided in the support member41, is operated to rotate the carrying pipe40, thus moving the supplied golf ball to the associated tee-up device20.

The above process is conducted in the tee-up device20provided in every swing compartment. Here, extra golf balls are preferably prepared in the carrying pipe40as well as in the tee-up device20. Remaining golf balls are continuously moved along the guide rail12. When the leading golf ball of the remaining golf balls is sensed by the detecting sensor13aof the driven unit13, a drive motor M of the drive unit10is reversely rotated, so that the remaining golf balls, which are in the guide rail12, are moved to the drive unit10and are discharged into the machine room.

As such, after the remaining golf balls have been carried into the machine room, golf balls are again carried to the floors through the elevator and are supplied to each swing compartment according to the number of golf balls used. Thereafter, remaining golf balls are moved to the machine room. This process is repeatedly conducted such that golf balls can always be ready in the swing compartments.

As described above, in the present invention, a golf ball carrying apparatus is installed in the floor of a driving range rather than being provided on the ceiling or some other place, so that it does not restrict the design of the driving range. Furthermore, unlike the conventional art, in which a portion of a mat is cut and removably installed to make it possible to repair the carrying apparatus between the swing compartments and to remove stuck golf balls, in the present invention, because processes of removing stuck golf balls and of repairing the carrying apparatus can be conducted without requiring removal of the mat, the mat can be integrally provided on the floor as a single body. Therefore, there is an advantage in that the clear and superior appearance of the driving range is ensured.
