Description

Underground automatic stadium pole device and multipurpose stadium system using the same {AUTOMATIC POLE APPARATUS OF COURT INSTALLED IN UNDERGROUND AND MULTI PURPOSE COURT SYSTEM USING THE SAME}

The present invention relates to the structure of equipment used in sports facilities, and in particular to a pole for supporting a net on both sides in a stadium using a net such as foot volleyball, tennis, volleyball, badminton, etc., and a stadium system using the same.

Because the space of the playground is limited, it is difficult to individually install stadiums for various sports such as foot volleyball courts, tennis courts, volleyball courts, and badminton courts. In particular, poles must be erected in stadiums where nets must be installed as shown above, but since the specifications and heights of the nets are all different, there is no choice but to select one event, erect a pole, and draw a line dedicated to that stadium. There is a problem that if a stadium dedicated to a specific sport is installed in a stadium used by the general public, the diverse demand for other sports cannot be satisfied.

In some playgrounds, lines for multiple playing fields are drawn and mobile pole devices are used to respond to the demand for various sports, but since they are not fixed in the ground, they are not stable and storage is difficult.

In describing the present invention, detailed descriptions of related known functions will be omitted if they are obvious to those skilled in the art and are judged to unnecessarily obscure the gist of the present invention.

Hereinafter, with reference to the attached drawings, an underground buried automatic stadium pole device (hereinafter referred to as 'pole device') according to an example of the present invention and a multi-purpose stadium system using the same will be described in more detail.

Figure 1 is a schematic plan view of a multi-purpose stadium system according to the present invention, Figure 2 is a schematic cross-sectional view of the pole device shown in Figure 1 in a state buried underground, and Figure 3 is a state in which the pole protrudes from the ground in the state of Figure 2. This is a schematic cross-sectional view of .

Referring to the drawings, a multipurpose stadium system 300 according to an example of the present invention includes a multipurpose stadium 200 provided indoors or outdoors, and a plurality of pole devices 100. As shown in the drawing, the multipurpose stadium 200 refers to a place of a certain area where a plurality of different sports can be played, such as a foot volleyball court 210, a volleyball court 220, and a tennis court 230. It also refers to a stadium for sports where a net is installed. At this location, lines may be drawn for each sport, or lines may be formed for each specific game. In this example, three items can be performed.

A plurality of pairs of pole devices 100 are provided in the multipurpose stadium 200. In other words, in order to install a net, there must be poles on each side of the stadium, so three pairs of pole devices are needed for three different sports. Of course, it is possible to install a pair of poles on both sides of the largest standard stadium, but since the location where the poles are installed is determined for each game, it is desirable to provide a pole device according to the specifications for each event.

In this example, a pair of pole devices 111 and 112 for the foot volleyball court 210 are provided on both sides of the foot volleyball court, and similarly, a pair of pole devices 121 and 122 exclusively for the volleyball court 220 and a pair of pole devices 121 and 122 for the tennis court 230. The pole devices 131 and 132 are each installed at positions determined by the regulations of the corresponding game. Since the net is installed in the center of the stadium, as shown in FIG. 1, three pairs of pole devices 100 are arranged in a line and spaced apart from each other along the center line of the multi-purpose stadium.

The reason why the multi-purpose stadium system of the above configuration can be operated is because the pole device is buried in the ground, and this is the biggest feature of the present invention. If poles or pole equipment protrudes from the ground, events that require extensive use of the playing field cannot be played. For example, if you want to use it as a tennis court 230 in FIG. 1, but the volleyball court pole devices 121 and 122 protrude from the ground, it cannot be used as a tennis court. All pole equipment other than the pole equipment for the event currently in progress is constructed to be buried in the ground, allowing various events to be performed in the same place.

Below, the underground buried type automatic pole device will be described in more detail.

The pole devices shown in FIGS. 2 and 3 are the pole devices indicated by reference numerals 112 and 132 in FIG. 1 . That is, it is installed on the right side of the foot volleyball court 210 and the tennis court 230, and although there is a difference in size, the configuration is the same.

The pole device according to the present invention includes a housing (10), a pole (20), and a drive unit.

The housing 10 is formed to be long in the vertical direction and is installed buried in the ground (G). A receiving portion 19 is formed inside the housing 10 to accommodate the pole 20, which will be described later. The height of the housing 10 is slightly higher than the height of the pole specified in the relevant game regulations. In this example, the housing 10 was manufactured by blocking the bottom of a hollow pipe.

The pole 20 is used to support the net installed in the stadium by tying it, and is formed to be long in the vertical direction. The pole 20 can be raised and lowered between a first position accommodated in the receiving portion 19 inside the housing 10 and a second position protruding from the upper side of the housing 10, that is, toward the ground. In this example, the pole 20 uses a hollow steel pipe, and its diameter is slightly smaller than that of the housing 10.

A holder 24 is coupled to the upper part of the folder 20, and a pair of rollers 25 are coupled to the holder 24 so that they can rotate in place. As shown in FIG. 4, the pair of rollers 25 are mounted on the upper string 1 of the net, and when the upper string 1 is pulled or released, the upper string 1 comes into contact with the upper string 1. guide.

Additionally, a cover plate 27 is provided spaced upward from the pole 20. In this example, the cover plate 27 is fixed to the pole 20 by the connecting rod 28. The cover plate 27 seals the housing 10 when the pole 20 is in the first position buried in the ground. And it is placed horizontally and formed flat so as to form a flat surface without protruding from the ground surface.

In addition, as shown in Figure 4, the upper rope (1) and lower rope (2) of the net are fixed to the pole 20. In this example, for this purpose, an upper through hole 21 and a lower through hole 22 are formed on the upper and lower sides of the pole 20, respectively. In this example, the upper through hole 21 and the lower through hole 22 are disposed at opposite positions of the pole 20. That is, both the upper through hole 21 and the lower through hole 22 are formed along the center line of the stadium. The lower through hole 22 is formed on the side closer to the stadium, and the upper through hole 21 is formed on the far side from the stadium. is formed In the case shown in the drawing, since it is a pole device placed on the right side of the stadium, the lower through hole 22 is on the left and the upper through hole 21 is on the right. However, in the case of a pole device placed on the left side of the stadium, the lower through ball will be placed on the right and the upper through ball will be placed on the left. That is, they are arranged symmetrically.

As shown in FIG. 4, the upper string 1 of the net is mounted on a pair of compression rollers 25 and then inserted into the interior of the pole 20 through the upper through hole 21. Inside the pole 20, a pair of pressing rollers 41 and 42 are installed to face each other and can rotate in place. The upper string (1) is inserted in a pressed state between the pressing rollers (41, 42). By rotating the pair of compression rollers 41 and 42 in one direction or the other, the upper string 1 of the net can be pulled or released. Although not shown, in this example, a motor, etc. is installed on a pair of compression rollers 41 and 42 so that the upper rope 1 can be pulled or released by a remote control means such as a remote control. The upper string (1) is fixed between the pressing rollers (41, 42). However, in another example, a stopper or the like may be installed on a pair of compression rollers to prevent the compression rollers from rotating due to unwanted external force. If the compression roller does not rotate, the upper string (1) is fixed in position without being pulled or released.

The lower line (2) of the net is inserted into the pole (20) through the lower through hole (22) and is provided with a fixing part (50) through which the lower line (2) can be tied or hung. In this example, the fixing part 50 uses a ring through which the lower string 2 can be tied or hung.

The driving unit is for lifting the pole 20 in the vertical direction and can employ various means. In this example, the drive unit includes a drive unit 31 fixed to the housing 10, and a piston unit 32 that is raised and lowered by the operation of the drive unit 31 and whose upper end is fixed to the pole 20. In this example, the drive unit may be a linear actuator driven by a motor, or a cylinder operated by pneumatic or hydraulic pressure may be used. Therefore, the driving part 31 can be a motor or a cylinder through which pressure fluid flows, and the piston part 32 can be a shaft that is raised and lowered by a motor or cylinder. In this example, the end of the piston portion 32 is fixed to the coupling table 23, and the coupling band 23 is fixed to the pole 20. That is, the piston part 32 is fixed to the pole 20 via the coupling table 23.

In the pole device 100 having the above-described configuration, the pole 20 is normally located in the ground while being accommodated in the receiving portion 19 of the housing 10, as shown in FIG. 2. In this state, only the cover plate 27 is visible from the ground, and the cover plate 27 is located on the same plane as the ground, keeping the overall stadium in a flat state. And when using the stadium, the drive unit is activated to protrude the pole 20 from the ground as shown in FIG. 3. In this example, the driving unit can be automatically raised and lowered using a remote control means such as a remote control.

When each pole 20 rises in a pair of pole device, the upper rope 1 and lower rope 2 of the net are fixed to the poles 20, respectively, as shown in FIG. The upper rope (1) of the net is fixed by pressing on a pair of compression rollers (41, 42), and then the upper rope can be pulled or released by rotating the compression rollers (41, 42) with a motor, etc. Installation of the net is completed by fixing the upper rope (1) and then fixing the lower rope (2) to the fixing part (50).

Meanwhile, the description has been made so far using the foot volleyball court 210 and the tennis court 230 where the net is installed low, but the net may be installed high like the volleyball court 220. In this case, the height of the pole must also be high. The present invention provides a structure that can raise and lower the pole in multiple stages for games using high poles, such as volleyball and badminton. Figure 5 is for explaining a pole device that is raised and lowered in two stages.

In Figure 5, the structures of the housing 10 and the pole 20 are all the same as the examples described above. Among the reference numbers in FIG. 5, all numbers that are the same as the reference numbers in FIGS. 2 to 4 have the same configuration, so a detailed description thereof will be omitted. The difference between the example of FIG. 5 and the previous example is that the driving unit is composed of a plurality of drive units to enable multi-level lifting and lowering.

Figure 5 shows a two-stage lifting structure, in which two drive units (70, 80) of the same configuration as the drive unit described above are installed at the top and bottom. The first driving unit 70 includes a first driving unit 71 fixed to the housing 10 and a first piston unit 72 that is raised and lowered by the operation of the first driving unit. And the end of the first piston part 72 is connected to the second drive unit 80. In this example, the tip of the first piston unit 72 is fixed to the intermediate support plate 73, and the second drive unit 80 is also installed on the intermediate support plate 73. The second driving unit 80 is also raised and lowered by the second driving unit 81 coupled to the intermediate support plate 73 and the operation of the second driving unit 81, and the upper end 83 is connected to the coupling base 23 of the pole 20. ) is provided with a second piston portion 82 fixed to the.

The first driving unit 70 operates to raise and lower the pole 20 by one stage, and the second driving unit 80 operates to raise and lower the pole 20 by two stages. This two-stage lifting structure allows the pole to be taller and the net to be installed higher.

Other configurations other than the driving unit and the two-stage lifting structure are the same as the example described above, so further explanation will be omitted.

As described above, in the present invention, the pole device is installed buried in the basement of a multi-purpose stadium, and the pole device dedicated to the game is operated to install the pole only when a game is played. As a result, a variety of different sports can be held in one stadium. Not only does the space utilization of the playground improve, but it also has the advantage of being able to meet the demand for a variety of games.

In the above, the multipurpose stadium is described and shown as being installed in an outdoor playground, but in the present invention, the multipurpose stadium naturally also includes an indoor stadium. When the pole device is said to be buried underground, in the case of an indoor stadium, the expression can be replaced by saying that it is buried under the floor of the indoor stadium (court).

The scope of protection of the present invention is not limited to the description and expression of the embodiments explicitly described above. In addition, it is to be added once again that the scope of protection of the present invention may not be limited due to changes or substitutions that are obvious in the technical field to which the present invention pertains.
