Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a facility for golf batting practice, and in particular, is a facility for practicing all kinds of shots other than those related to the flight distance of the ball. This relates to a capsule-type training facility that is formed into a portable unit and is movable.

BACKGROUND TECHNOLOGY A full-fledged golf practice facility, as shown in Fig. 4, consists of an open space with a length equivalent to one hole on a golf course, with a width of several dozen batting seats. It is known to have a steel frame structure on three sides, with nets attached to the sky and side walls, and a two-story batting area along one side. Such a practice facility typically requires a site of 100m to 200m in length and tens of meters in width, and construction costs are high, so it is necessary to set up various equipment such as a golf center and operate it as a company. ing.

On the other hand, golf is a sport that is becoming increasingly popular both as a leisure sport and as a social sport.
Many golfers want to practice in a place close to their daily lives, and if there is a vacant space such as a recreational facility or the roof of a building, they can practice at least basic batting practice. Facilities are needed. To this end, simple screen-type net stands such as those used in home gardens are commercially available, or a three-dimensional frame made of steel pipes is used.
A tunnel-shaped net is placed over this to prevent the balls from flying away, and the players practice with an emphasis on the basics of shooting in order to prepare for the sunny course. Therefore, a practice protector as shown in FIG. 42 is provided not only for the above-mentioned full-scale golf practice range but also for other commercial and recreational uses.

The one shown in the figure is a gate-shaped frame made by gently curving steel pipes, with support plates provided at both lower ends, and two frame materials assembled into a three-dimensional frame shape using different braces of steel bars. A net made of rigid resin is stretched along one side wall, supported by ropes or wires, and a shot mat is placed on the opening side, from which the ball is driven toward the net.

These assembled units are lightweight and can be easily used for home use as mobile units, but by installing a large number of these units, they can be used for commercial purposes such as golf lessons and golf schools. It can also be used for

Problems that the invention aims to solve A full-scale practice range as shown in Figure 4-1 should be a satisfactory practice facility for a golf course excluding the matchmaking area, but its construction itself requires a vast area. It requires land or vacant space, requires a large investment of capital, and imposes restrictions on the user's time-consuming journey. In short, the practice facility shown in Figure 2 is nothing more than special equipment for handling batted balls, and is intended only to prevent the harm caused by batted balls to the surrounding area, and at the same time, to prevent batted balls from scattering. The only benefit is that it can be done. In other words, it has nothing to do with the exercise of the user itself, and is only used as a tool, and has no protection against rain or wind, and is forced to be used indoors, and must be moved outdoors or indoors. No.

In addition, although it is possible to use gentle curves for the frame material, exposing the brace members as diagonal members will spoil the aesthetics, and the protrusion of support plates of column bases and assembly members will be a concern. It lacks smartness from a sales perspective.

Furthermore, the position of the shot pine is not constant with respect to the protective body, making it unsuitable for delicate shot observation using instruments. In addition, to recover the batted balls, it is necessary to collect the balls scattered on the floor.

Means to Solve the Problems The practice cage of the present invention was not only developed to address the problems of conventional protective nets, but was also developed from the perspective of a building as a complete facility for use as a practice field. be. We decided to call this facility a "cage" because it resembles a batting cage used in baseball, but from a golf clinic perspective it is a kind of "capsule."
However, in terms of architectural technology, it is also a kind of "prefab house." The cage of this design consists of a unit unit consisting of a shot room where users can practice the basics of shooting, and a protective body that handles batted balls, and can be used as a practice facility for personal or business use. With this in mind, in the shot room, the floor base and pipe material are assembled into a frame structure, and the main body part is covered with membrane material, and in the protective body part, the pipe material frame is covered with net material. It has a structure that can be stretched, expanded and folded, and the entire cage that connects these parts can be moved and fixed. In this way, although the cage of the present invention is a structural unit in the form of a living room, it can be provided as a simple mobile practice facility without being subject to building regulations in terms of floor area ratio or floor space. It was completed in .

In addition to these facilities, a batted ball observation device using electronic equipment can be used, and a built-in computer can calculate the initial velocity and flight distance of the batted ball. Practice methods can also be adopted to compensate for certain deficiencies.

The cage of this invention has a full length as a unit structure.
The length is 7.2m, the width is 3.0m, the height is 0.3m to the floor, and the ceiling height of the shot room is 3.2m, and the total length of the shot room and the protective body is divided approximately 1:2. of course,
These dimensions show one example, and are not limited to the above. When the base frame 32 is raised up with the connecting portion 31 as the base end, the frame members 34, 35
The total volume of the cage 1 can be reduced to less than 1/2 by stacking the cages and folding the net material 37. At this time, since the longest frame material 34 is 5 m or more in height, the base end of each frame is removed from the connection part 31, taken into the indoor side of the shot, and the end frame material 2
4 can be held.

This cage is equipped with the necessary electrical wiring in advance and integrated into a switch panel installed on the wall, and power is supplied from outside as appropriate.

Function The function of the unit cage of the present invention can be better understood by explaining how to use it.

First, the entire assembly is made by assembling the main body 2 and the protector 3 and connecting them to form the unit cage 1. Wheels 41 and 42 and outriggers 4 run on the lower surface side of the base 21 of the main body 2 and serve as fixing means 4.
Install 3. The legs of inverted U-shaped frame members 22 and 24 are fixed to the side edges of the upper surface, and the frame member of the entrance/exit 25 is erected. Next, the frame of the opening 26 is attached to the frame material 22, and the frame material 22 and the frame material are covered with the membrane material 23 and fixed from the inside, thereby completing the outer shell of the shot chamber.

The connecting part 31 is attached to the base 21, and the base frame 32 with the wheels 44 and outriggers 45 attached to the lower surface and the frame members 35 and 34 are attached in order to both ends of the connecting part 31, and at the position where the wire 36 of the regulating material extends. It has a radial shape when viewed from the side, and a net material 37 is stretched on the inner surface to support it from each frame material. The front end of the net material is attached to the frame material 24 of the main body. Finally, the net material 38 is stretched within the plane of the U-shaped frame of the frame material 35,
The front end thereof is attached so as to face inside the groove 39 of the connecting part 31. It is recommended that a reinforcing rope be placed along the membrane material 23 and the net materials 37 and 38, and the membrane material 2
3. The net materials 37 and 38 can be easily stretched.

During this time, in the main body 2, the floor 51 of the shot room is laid on the top surface of the base 21, artificial turf 52 is spread on it, and mats, electric appliances, and electrical equipment are installed to complete the shot room. Thus, the entire assembly of the cage 1 is completed.

The unit cage 1 of this invention has a total weight of about 300 kg, and if 15 cm diameter wheels are used as running wheels, it can be towed and moved by hand, and it can be fixed at any desired position. can.
Moreover, two-layer installation is also possible by using an appropriate frame. If the dimensions of the unit cage are determined as shown in the example, it will not be subject to road traffic law regulations, and the unit can be mounted on a trolley with tires of approximately 50 to 60 cm and used as a unit in a normal passenger car. It is possible to tow long distances.

The method of using the unit cage 1 installed in a predetermined position is clear according to the above-described configuration, and the user can practice swings, shots, etc. in the shot room. It is also clear that the ball hit at this time is prevented from flying by the net material 37 of the protector 3 and does not cause any harm to the surroundings. Furthermore, in this invention, since a soundproof material is used as the net material 37, the impact noise of the ball is greatly reduced. In this invention, the bottom net material 3 is stretched over the frame material 35.
It incorporates 8 characteristics. That is, net material 37
All the balls that hit and fall roll toward the shot chamber side along the slope of the net material 38 and are concentrated in the groove 39 and collected, so the user does not have to pick up the balls inside the protector 3. , you can collect the ball at a very close location. In addition, since the back part protrudes rearward and does not require support, it can be placed above the pool water surface, making it highly efficient for use during the off-season of the pool.

Internal equipment can be attached according to specifications as necessary.

Effects of the invention The effects of the unit cage of the invention are listed below.

1. Although it is a prefabricated structure used as a practice field, it is not subject to floor area or floor area ratios, so the installation location can be freely selected, and the overall light weight makes it especially advantageous for installation on the roof of a building. It is. Therefore, the degree of use is increased in urban areas such as hotels and department stores.

2. Easy to assemble, install, and move, and because it is small, it can be placed freely, requires a small area for a single unit or a combination of multiple units, can be used in a golf equipment store, and can be moved without using the existing floor. I don't regret it.

3. Since the unit can be assembled and disassembled, it does not require a large amount of storage space. Furthermore, the combination of the protective parts can be changed between units whose specifications have been changed.

4. Since it has a shot room, it can be used in hot weather, cold wind, rainy weather, and at night, and it is also possible to practice privately without worrying about being seen. In addition, various training equipment can be installed inside the room to promote the effectiveness of practice, and the floor is finished with artificial turf.

5. Retrieval of batted balls is automatic, saving troublesome labor and time.

6 It has a capsule shape with mainly curved lines throughout, and together with the stainless steel frame material, it creates an urban-like space, and the color of the membrane material can be varied from muted to bright colors.

The unit cage of this invention is not only used as a hit ball protector as an accessory for golf practice as in the past, but is also designed to accommodate all of the user's practice behavior as a shot practice room similar to that of a building facility. Because it was developed as a compact driving range, it can be attached directly to a golf course or conventional golf driving range, or it can be used as a single unit or in combination with multiple units, in any location requested by the user. This will contribute to all industries related to golf, such as sports and leisure.
