Description

本発明は野球場のグラウンド上の特定の領域に空調空気を送ることが可能な野球場における空調設備に関するものである。   TECHNICAL FIELD The present invention relates to an air conditioning facility in a baseball field that can send air-conditioned air to a specific area on the ground of the baseball field.

例えばグラウンドの上空に架設される屋根が上空を完全に閉鎖する形式の屋根架構付きの野球場では、空調空気が屋外に放出されることがないため、屋内に空調空気が供給され続ければ、屋内全体をある程度、無駄なく空調することはできる(特許文献1参照)。   For example, in a baseball stadium with a roof frame in which the roof erected above the ground completely closes the sky, the conditioned air will not be released outdoors, so if the conditioned air continues to be supplied indoors, The whole can be air-conditioned to some extent without waste (see Patent Document 1).

一方、屋根がグラウンドの上空を完全には閉鎖しない開放型の場合には、または屋根架構付きでない野球場では、空調空気が屋外に放出されるため、屋内全体を効率的に空調することが難しい。これらの場合には、観客席やダッグアウトのようなグラウンド外の特定の、限られた空間に対して個別に空調することになる(特許文献2参照)。   On the other hand, if the roof is an open type that does not completely close the sky above the ground, or in a baseball field that does not have a roof frame, it is difficult to efficiently air-condition the entire indoor area because air-conditioned air is released outdoors. . In these cases, a specific limited space outside the ground, such as the audience seats and dugout, is individually air-conditioned (see Patent Document 2).

屋根の有無に関係なく、グラウンドの地中に敷設されたダクトを通じ、空調機から送られた空気をグラウンド側へ向けて吹き出す方法はある(特許文献3参照)。但し、この場合の空気はグラウンド上の全面に敷設された人工芝をグラウンド表面(地盤面)から分離させる目的で吹き出され(段落0007)、人工芝より上の空間に空調空気として放出される訳ではないため、グラウンド上の空調に利用されることはない。   There is a method of blowing the air sent from the air conditioner toward the ground side through a duct laid underground in the ground regardless of the presence or absence of a roof (see Patent Document 3). However, in this case, the air is blown out for the purpose of separating the artificial grass laid on the entire surface of the ground from the ground surface (ground surface) (paragraph 0007), and is discharged as air-conditioned air into the space above the artificial grass. Is not used for air conditioning on the ground.

実開平6−10741号公報(請求項1、図1〜図5)Japanese Utility Model Laid-Open No. 6-10741 (Claim 1, FIGS. 1 to 5) 特開平6−200645号公報(請求項1、図1、図2)JP-A-6-200645 (claim 1, FIG. 1 and FIG. 2) 特開平6−48506号公報(請求項1、段落0007、図1、図2)JP-A-6-48506 (claim 1, paragraph 0007, FIG. 1, FIG. 2)

特許文献2では空調空気を受ける対象は観客かベンチ内の選手等であるため、グラウンド上にいる選手や審判に向けられることはない。   In Patent Document 2, since the target to receive the conditioned air is a spectator, a player on a bench, or the like, it is not directed to a player on the ground or a referee.

特許文献3ではグラウンド表面から離脱した帯状の人工芝の脇から吹き出された空気がグラウンド上に漏れることは考えられる。しかしながら、グラウンド上に選手や審判がいるときにはグラウンド上面の全面に人工芝が敷設された状態にあるから、吹出口から選手等に対して空気が放出されることはないため、グラウンド上の選手等に向けて空調されることはない。特許文献3ではまた、、吹出口がグラウンドの全面に分散して配置されているため、仮に空調用に使用されることができたとしても、グラウンド上の特定の領域に集中的に空調空気を放出することはできない。   In Patent Document 3, it is conceivable that the air blown out from the side of the belt-shaped artificial turf separated from the surface of the ground leaks onto the ground. However, when there are athletes and referees on the ground, artificial turf is laid on the entire upper surface of the ground, so air will not be emitted to the athletes etc. from the outlet, so the athletes on the ground, etc. There is no air conditioning towards. Further, in Patent Document 3, since the air outlets are dispersed and arranged on the entire surface of the ground, even if it can be used for air conditioning, the conditioned air is concentrated in a specific area on the ground. It cannot be released.

このように従来、グラウンド上にいる特定の領域の選手等を対象にした空調は行われていない。   As described above, conventionally, the air conditioning has not been performed for players or the like in a specific area on the ground.

本発明は上記背景より、野球場のグラウンド上にいる特定の領域の選手等に向け、集中的に空調することを可能にする野球場における空調設備を提案するものである。   From the above background, the present invention proposes an air-conditioning facility in a baseball field that enables intensive air-conditioning for players and the like in a specific area on the ground of the baseball field.

The air-conditioning equipment in the baseball field of the invention according to claim 1 is, on the ground of the baseball field,
A surface material that is buried in the ground with the surface facing the space above the ground, and an air conditioner or a blower that communicates with a cavity formed on the lower surface side of the surface material and is installed outside the ground. With and
Between the surface and the lower surface of the surface material, an opening for communicating both surfaces is formed ,
In the ground below the surface material, the box that forms the cavity and supports the surface material is embedded,
The box body has a side wall holding the surface material, and the box body is installed in the ground to a depth such that an upper end portion of the side wall is completely buried in the ground .
The air conditioner for a baseball field of the invention according to claim 2 is the air conditioner for a baseball field according to claim 1, wherein the upper end portions of the side walls facing each other are in close contact with side surfaces of the surface material, It is a constituent requirement that the side surface is clamped to the center side.

表面材2は例えば図4等に示すようにグラウンド1上の空間に面する上面が平坦面、または平坦面に近い曲面状、もしくは多角形状をした板状の、またはブロック状の部材であり、材料には主に木材、プラスチック、ゴム、鋼材、コンクリートブロック等が使用される。但し、開口21が形成可能であれば、表面材2の材料は問われない。表面材2は地中に埋設されるため、平面上はグラウンド1内に配置される。   The surface material 2 is, for example, a plate-shaped or block-shaped member whose upper surface facing the space on the ground 1 is a flat surface, or a curved surface close to a flat surface, or a polygonal shape as shown in FIG. Wood, plastic, rubber, steel, concrete blocks, etc. are mainly used as materials. However, the material of the surface material 2 does not matter as long as the opening 21 can be formed. Since the surface material 2 is buried in the ground, it is arranged in the ground 1 on the plane.

グラウンド1上の空間に面する表面材2の「表面」は主に表面材2の上面、もしくは側面(周面)であり、この上面と側面の少なくともいずれかが表面材2の表面になる。表面材2の開口21は表面材2の下面と上面間、または下面と側面間を貫通して形成され、この両面を連通させる開口21は空気の吹出し口になる。下面と上面間を貫通する開口21と、下面と側面間を貫通する開口21が共に形成されることもある。表面材2の下面は空洞3に面し、空洞3は空調機7、もしくは送風機に直接、またはダクト6を通じて間接的に連通する(請求項)。「グラウンド1上の空間に面する」は「グラウンド1の表面に露出する」とも言い換えられる。 The “surface” of the surface material 2 facing the space on the ground 1 is mainly the upper surface or side surface (peripheral surface) of the surface material 2, and at least one of the upper surface and the side surface is the surface of the surface material 2. The opening 21 of the surface material 2 is formed so as to penetrate between the lower surface and the upper surface or between the lower surface and the side surface of the surface material 2, and the opening 21 that communicates both surfaces serves as an air outlet. An opening 21 penetrating between the lower surface and the upper surface and an opening 21 penetrating between the lower surface and the side surface may be formed together. The lower surface of the surface material 2 faces the cavity 3, and the cavity 3 communicates with the air conditioner 7 or the blower directly or indirectly through the duct 6 (claim 3 ). The phrase "facing the space on the ground 1" can be restated as "exposing on the surface of the ground 1".

表面材2はグラウンド1内の主として守備に付いたときに選手が居る位置、またはその付近等に設置され、少なくとも上面がグラウンド1上に面した状態で地中に埋設される。「グラウンド1内」にはグラウンド1に隣接する場合のブルペンも含まれる。   The surface material 2 is installed in the ground 1 mainly at a position where the player is present when the player is on the field, or in the vicinity thereof, and is buried in the ground with at least the upper surface facing the ground 1. The “inside ground 1” includes a bull pen adjacent to ground 1.

表面材2は具体的には図1に示すように主にグラウンド1上でのプレーに支障のない、例えば滑り止め剤やスパイクの泥落とし等が設置されるピッチャーズプレートの後方に隣接する位置、またはその後方位置の他、キャッチャーの守備位置や主審の構え位置、各塁ベースの付近、ネクストバッターズサークル内やコーチャーズボックス内等に設置される。ピッチャーズプレートとホームベース及び各塁ベースには野球規則上、開口を形成することができないため、表面材2がこれらを兼ねることはなく、これらピッチャーズプレート等は表面材2の対象からは除外される。前記ブルペンのピッチャーズプレート付近やホームベース付近も設置対象になるが、ブルペン内ではピッチャーズプレートやホームベース自体が表面材になることもある。   Specifically, as shown in FIG. 1, the surface material 2 is located at a position adjacent to the rear of the pitcher's plate where the play on the ground 1 is mainly prevented, for example, an anti-slip agent or spud mud is installed. , Or its rear position, it is installed in the defensive position of the catcher, the position of the referee's stance, the vicinity of each base, the next batters circle, the coachers box, etc. According to the rules of baseball, it is not possible to form an opening in the pitchers plate, home base and each base, so the surface material 2 does not serve as these, and these pitchers plates are excluded from the target of the surface material 2. To be done. Although the vicinity of the pitcher's plate of the bull pen and the vicinity of the home base are also targets for installation, in the bull pen, the pitcher's plate or the home base itself may be the surface material.

空調機7には屋内の空気と屋外の空気を入れ換え、外気の温度を調整して外気を屋内に取り入れる空気調和機と、冷媒の圧縮と膨張による温度変化を利用して屋内の空気の温度を降下、または上昇させるエアーコンディショナーの2通りの形式がある。後者の場合、空調機7は図1に示すように屋内の空気の吸気と送風をする室内機72と、外気を取り入れ、外気と冷媒を室内機72で熱交換させる室外機71から成立する。ここで言う「屋内」は屋根架構の有無に拘わらず、グラウンド1上を指し、「屋外」はグラウンド1上の外部を指し、バックネット裏と内野席及び外野席等が該当する。   The air conditioner 7 replaces indoor air with outdoor air, adjusts the temperature of the outside air to take in the outside air indoors, and uses the temperature change due to the compression and expansion of the refrigerant to control the temperature of the indoor air. There are two types of air conditioners that can be lowered or raised. In the latter case, the air conditioner 7 is composed of an indoor unit 72 that sucks and blows indoor air as shown in FIG. 1, and an outdoor unit 71 that takes in outside air and exchanges heat between the outside air and the refrigerant in the indoor unit 72. The term "indoor" as used herein refers to the ground 1 regardless of the presence or absence of a roof frame, and the term "outdoor" refers to the outside on the ground 1, such as the back net back, infield seats, and outfield seats.

送風機は温度調整(温度変化)を伴うことなくその場の空気を表面材2側へ送る装置であるが、設置場所が空調された空間であれば、表面材2からの空気の放出先では空調機から供給された空調空気と同様の効果を得ることはできる。また空調されていない空間であっても、無風時、あるいは微風時には特定の領域に居る選手や審判等に風を送ることで、猛暑時の冷涼効果(空気及び気化熱による除熱効果=扇風機効果)を得ることは可能であるため、送風機は空気調和機の一部でもあると言える。以下、空調機7と送風機を合わせて空調機7等と言い、空調機7等から供給された空気を空調空気等と言う。   The blower is a device that sends the air on the spot to the surface material 2 side without temperature adjustment (temperature change). However, if the installation location is an air-conditioned space, the air is discharged from the surface material 2 to the air conditioner. It is possible to obtain the same effect as the conditioned air supplied from the machine. Even in a non-air-conditioned space, by sending wind to athletes and referees in a specific area when there is no wind or when there is a slight breeze, cooling effect during extreme heat (heat removal effect by air and vaporization heat = fan effect) It is possible to say that the blower is also a part of the air conditioner. Hereinafter, the air conditioner 7 and the blower will be collectively referred to as the air conditioner 7 and the like, and the air supplied from the air conditioner 7 and the like will be referred to as the conditioned air and the like.

表面材2と空調機7等は表面材2の下方に、下面に連続して形成される空洞3を介して、または表面材2と空調機7等間に敷設され、双方に接続されるダクト6と空洞3を介して結ばれ(請求項)、空調機7等から供給された空調空気等は空洞3を通じて表面材2にまで送られ、表面材2の開口21を通じてグラウンド1上の空間に放出される。 The surface material 2 and the air conditioner 7, etc. are laid below the surface material 2 via a cavity 3 formed continuously on the lower surface or between the surface material 2 and the air conditioner 7, etc., and are connected to both ducts. 6 is connected to the surface material 2 through the cavity 3 (Claim 3 ) and is supplied from the air conditioner 7 or the like to the surface material 2 through the cavity 3 and the space on the ground 1 through the opening 21 of the surface material 2. Is released to.

表面材2はグラウンド1上の全面に分散するのではなく、前記の通り、図1に示すように平面上、グラウンド1内の限られた特定の箇所、もしくはグラウンド1外のグラウンド1に面する特定の箇所、または双方に配置されるため、開口21から放出される空調空気等はグラウンド1上の特定の領域に放出される。この結果、野球場のグラウンド1上にいる特定の領域の選手や審判に向け、集中的に空調することが可能になる。   The surface material 2 is not dispersed over the entire surface of the ground 1, but as described above, faces the flat surface, a limited specific place in the ground 1, or the ground 1 outside the ground 1 as shown in FIG. Since it is arranged at a specific place or both, the conditioned air or the like discharged from the opening 21 is discharged to a specific area on the ground 1. As a result, it becomes possible to intensively air-condition the players and the referee in a specific area on the ground 1 of the baseball field.

特にグラウンド1内に加え、グラウンド1外のグラウンド1に面する位置にも表面材2が配置された場合には、グラウンド1上の特定の領域を空調しながらも、グラウンド1上の空間を全体的に空調する効果を得ることができるため、屋根架構付き野球場内で空調される場合と同等の空調効果を得ることが可能になる。   In particular, when the surface material 2 is arranged not only in the ground 1 but also in a position facing the ground 1 outside the ground 1, the entire space on the ground 1 is controlled while air-conditioning a specific area on the ground 1. Since it is possible to obtain the effect of air-conditioning, it is possible to obtain the same air-conditioning effect as when air-conditioning in a baseball field with a roof frame.

加えて図1、図2に示すようにバックネット裏と内野席の最前列や外野席の最前列、またはこれら最前列前の通路等に、本発明の空調設備を構成する表面材2とは別の吹出し口8をグラウンド1側へ向けて設置し、本発明の空調設備に通常の屋内施設用の空調設備を併用すれば、グラウンド1上への、あるいは野球場内での空調効果を向上させることが可能になる。   In addition, as shown in FIG. 1 and FIG. 2, the surface material 2 constituting the air conditioning equipment of the present invention is provided on the back net and the front row of the infield seats, the front row of the outfield seats, or the passages in front of these front rows. If the air-conditioning equipment of the present invention is used together with the air-conditioning equipment of the present invention, the air-conditioning effect on the ground 1 or in the baseball field is improved. Will be possible.

屋根架構付き野球場では、夏季、屋根と観客席の存在によりグラウンド1上に沿う通風が妨げられ、暑さによる不快度が高まることがあるが、グラウンド1の表面から供給される夏季の空調空気である冷気がその比重により下部に滞留しようとするため、屋根架構付きでありながらも、限られた領域に対する空調効率は一層高まる。   In a baseball field with a roof frame, the presence of roofs and spectators may prevent ventilation along Ground 1 in the summer, which may increase the discomfort caused by the heat. However, summer air-conditioned air supplied from the surface of Ground 1 Since the cold air, which is the above, tends to stay in the lower part due to its specific gravity, the air-conditioning efficiency for a limited area is further enhanced even with the roof frame structure.

なお、空調空気等を表面材2から特定の領域に放出し、特定の選手等に向けて空調することは、グラウンド1の上空に屋根が架設されるか否かには関係しないため、本発明の空調設備は屋根付きと屋根なしのいずれの形式の野球場にも適応する。   It should be noted that discharging conditioned air or the like from the surface material 2 to a specific area and air-conditioning it toward a specific player or the like does not relate to whether or not a roof is installed above the ground 1. The air-conditioning system is suitable for both covered and uncovered baseball fields.

表面材2板状等の場合には表面材2の下に形成される空洞3の平面積が大きくなる程、地盤が表面材2を支持しきれず、表面材2の周辺以外の中間部が下方へ撓むか、表面材
2自体が空洞3内に落下することが想定される。このことから、空洞3の平面積の大きさ、あるいは表面材2自体の剛性の程度によっては、表面材2の下の地中に、空洞3を形成する箱体4を埋設し、この箱体4に表面材2を支持させることが適切ある(請求項)。箱体4には空調機7等が、または空調機7等に接続されたダクト6が接続される(請求項)。
When the surface material 2 has a plate shape or the like, the larger the plane area of the cavity 3 formed under the surface material 2 is, the more the ground cannot support the surface material 2, and the intermediate portion other than the periphery of the surface material 2 is It is assumed that the surface material 2 itself bends downward or falls into the cavity 3. From this, depending on the size of the plane area of the cavity 3 or the degree of rigidity of the surface material 2 itself, the box body 4 forming the cavity 3 is embedded in the ground below the surface material 2, It is appropriate that the surface material 2 is supported on the surface 4 (Claim 1 ). An air conditioner 7 or the like or a duct 6 connected to the air conditioner 7 or the like is connected to the box body 4 (claim 3 ).

箱体4の内周面には図3に示すように内周面に沿い、表面材2の周辺等を支持するための受け部44を張り出して形成することができるため、表面材2をその平面積より小さい平面積の領域内に納まる受け部44に支持させることができる。結果として、箱体4が表面材2をその周囲で支持したときに、表面材2を撓ませずに、また落下させずに支持することが可能になる。   As shown in FIG. 3, a receiving portion 44 for supporting the periphery of the surface material 2 can be formed on the inner peripheral surface of the box body 4 as shown in FIG. It can be supported by the receiving portion 44 which is accommodated in a region having a plane area smaller than the plane area. As a result, when the box body 4 supports the surface material 2 around it, it is possible to support the surface material 2 without bending or dropping it.

表面材2の平面積より空洞3の平面積が小さい場合には、表面材2の周辺部分を地盤に支持させながら、表面材2の中央部分をその下に配置された箱体4に支持させることもある。この場合、表面材2の開口21は箱体4に支持(包囲)された領域に形成される。   When the plane area of the cavity 3 is smaller than the plane area of the surface material 2, the peripheral portion of the surface material 2 is supported by the ground, and the central portion of the surface material 2 is supported by the box body 4 arranged therebelow. Sometimes. In this case, the opening 21 of the surface material 2 is formed in the region supported (enclosed) by the box body 4.

受け部44は図4に示すように表面材2の周辺に沿って環状に形成される他、表面材2の周辺に沿った部分に加え、表面材2の全面の下に全体的に格子状に形成されることもある。受け部44はまた、表面材2の周辺に沿った部分に加え、表面材2の中央部分の下の部分に部分的に格子状に形成されることもある。受け部44が表面材2の中央部分の下にも格子状に形成される場合、表面材2は周辺と平面上の中間部(中央部)においても受け部44に支持されるため、支持状態での安定性が増す。   The receiving portion 44 is formed in an annular shape along the periphery of the surface material 2 as shown in FIG. 4, and in addition to the portion along the periphery of the surface material 2, it is entirely in a grid pattern under the entire surface of the surface material 2. It may be formed in. The receiving portion 44 may be partially formed in a grid pattern in a portion below the central portion of the surface material 2 in addition to a portion along the periphery of the surface material 2. When the receiving portion 44 is formed in a lattice shape below the central portion of the surface material 2, the surface material 2 is also supported by the receiving portion 44 at the peripheral portion and the intermediate portion (central portion) on the plane. Increases stability in.

但し、平面積の大きい表面材2が周辺部分において箱体4に支持される場合でも、表面材2自体の厚さを増すか、表面材2の下面に木材等を接合して補強する等により曲げ剛性を増すことをすれば、必ずしも箱体4の受け部44を格子状に形成しなくても表面材2の撓みと落下を防止することは可能である。   However, even when the surface material 2 having a large flat area is supported by the box body 4 in the peripheral portion, by increasing the thickness of the surface material 2 itself, or by bonding wood or the like to the lower surface of the surface material 2 for reinforcement. If the bending rigidity is increased, it is possible to prevent the surface material 2 from bending and falling even if the receiving portion 44 of the box body 4 is not necessarily formed in a lattice shape.

表面材2箱体4に支持されながら、水平方向の移動が拘束された状態に保持される場合があり、保持には図4に示すようにねじ45等による固定も含まれる。
The surface material 2 may be held in a state in which the horizontal movement thereof is restrained while being supported by the box body 4, and the holding includes fixing with screws 45 or the like as shown in FIG.

グラウンド上の空間に面した状態で地中に埋設され、空調機等に連通する開口を有する表面材を平面上、グラウンド内の限られた特定の箇所に配置するため、表面材の開口から放出される空調空気をグラウンド上の特定の領域に送ることができる。この結果、野球場のグラウンド上にいる特定の領域の選手や審判に向け、集中的に空調することができる。   The surface material, which is buried in the ground facing the space above the ground and has an opening that communicates with the air conditioner, etc., is placed in a limited specific place in the ground on a plane, so the surface material discharges from the opening. Conditioned air can be directed to specific areas on the ground. As a result, it is possible to intensively perform air conditioning for players and referees in a specific area on the baseball field.

図1、図2はグラウンド1上の空間に表面が面した状態で地中に埋設される表面材2と、表面材2の下面側に形成される空洞3に連通し、グラウンド1の外部に設置される空調機7、もしくは送風機(以下、空調機7等)とを備えた空調設備の配置状態を示す。   1 and 2 are connected to the outside of the ground 1 by communicating with the surface material 2 buried in the ground with the surface facing the space above the ground 1 and the cavity 3 formed on the lower surface side of the surface material 2. The arrangement | positioning state of the air conditioning equipment provided with the air conditioner 7 or blower (henceforth, air conditioner 7 etc.) installed is shown.

図1、図2ではグラウンド1内とグラウンド1外の境界よりグラウンド1内寄りに表面材2を配置している関係で、表面材2下の空洞3と空調機7等との間の地中には両者を連通させるダクト6が敷設されているが、表面材2がグラウンド1内とグラウンド1外の境界に配置されるような場合には、空洞3に直接、空調機7等が接続されることもある。グラウンド1内とグラウンド1外の境界はバックネット、もしくはその下の壁、内野席と外野席の壁、ダッグアウトの前面等になる。   In FIG. 1 and FIG. 2, the surface material 2 is arranged closer to the inside of the ground 1 than the boundary between the inside of the ground 1 and the outside of the ground 1, and the underground between the cavity 3 under the surface material 2 and the air conditioner 7 or the like. A duct 6 that connects the two is laid in the above. However, when the surface material 2 is arranged at the boundary between the inside of the ground 1 and the outside of the ground 1, the air conditioner 7 or the like is directly connected to the cavity 3. Sometimes The boundary between the inside of the ground 1 and the outside of the ground 1 is the back net or the wall below it, the walls of the infield seats and the outfield seats, the front of the dugout, and the like.

表面材2の表面と下面との間にはこの両面を連通させ、空洞3を通じて、または空洞3とダクト6を通じて空調機7等から供給される空調空気等を吹き出す吹出し口となる開口21が形成される。表面材2の表面はグラウンド1の表面に露出する面を指し、上面の場合と上面と側面の場合がある。空調空気等とは、空調機7から供給される空調空気と送風機から送られる空気を含む趣旨である。   The front surface and the lower surface of the surface material 2 are communicated with each other on both sides, and an opening 21 is formed as a blowout port for blowing out conditioned air or the like supplied from the air conditioner 7 or the like through the cavity 3 or through the cavity 3 and the duct 6. To be done. The surface of the surface material 2 refers to a surface exposed on the surface of the ground 1, and may be an upper surface or an upper surface and a side surface. The conditioned air and the like are meant to include conditioned air supplied from the air conditioner 7 and air sent from a blower.

空調機7はグラウンド1外の空気の温度を調整しながら、グラウンド1内の空気とグラウンド1外の空気を入れ換える空気調和機の単体である場合と、屋外の空気を取り入れながら、圧縮と膨張により温度変化した冷媒と屋外の空気との間で熱の授受をする室外機71と、屋内の空気を循環させながら、冷媒との熱交換によりグラウンド1内の空気の温度を上下させる室内機72から構成される場合がある。図1は空調機7が室外機71と室内機72から構成される場合の例を示している。図1に示す例の場合、室外機71と室内機72間には冷媒が循環する冷媒管73が敷設(架設)され、双方に接続される。   The air conditioner 7 is a unit of an air conditioner that exchanges the air inside the ground 1 with the air outside the ground 1 while adjusting the temperature of the air outside the ground 1, and by compressing and expanding while taking in the air outside. From the outdoor unit 71 that exchanges heat between the refrigerant whose temperature has changed and the outdoor air, and the indoor unit 72 that raises and lowers the temperature of the air in the ground 1 by exchanging heat with the refrigerant while circulating the indoor air. May be configured. FIG. 1 shows an example in which the air conditioner 7 is composed of an outdoor unit 71 and an indoor unit 72. In the case of the example shown in FIG. 1, a refrigerant pipe 73 through which a refrigerant circulates is laid (installed) between the outdoor unit 71 and the indoor unit 72 and is connected to both.

図1、図2ではまた、グラウンド1内とグラウンド1外の境界に通常の空調用の吹出し口8(ダクト)をグラウンド1内へ向けて設置し、吹出し口8からも空調空気等を放出することで、表面材2の開口21から放出される空調空気等によるグラウンド1内での空調効果を高めている。ここではグラウンド1内とグラウンド1外の境界としてのバックネット下の壁とダッグアウトの前面に吹出し口8を設置し、表面材2と同様に吹出し口8に空調機7(室外機71と室内機72)を接続している。   In FIG. 1 and FIG. 2, a normal air-conditioning outlet 8 (duct) is installed at the boundary between the inside of the ground 1 and the outside of the ground 1 toward the inside of the ground 1, and the conditioned air or the like is also discharged from the outlet 8. As a result, the air conditioning effect in the ground 1 by the air conditioning air or the like discharged from the openings 21 of the surface material 2 is enhanced. Here, an outlet 8 is installed on the wall under the back net as a boundary between the inside of the ground 1 and the outside of the ground 1 and the front of the dugout. 72) is connected.

図3はグラウンド1下の地中に埋設され、空洞3を形成する、例えば角柱状の箱体4に表面材2が支持される場合の、表面材2のグラウンド1中での設置状態を示す。箱体4は主に表面材2の下方に、空調機7等に、またはダクト6に連通する空洞3を形成するために地中に設置されるが、図3、図4に示すように表面材2を支持する役目を果たすこともある。只、表面材2は地盤にのみ支持されることもあるため、箱体4は必ずしも表面材2を支持する必要はない。表面材2は地盤と箱体4に支持されることもある。   FIG. 3 shows an installation state of the surface material 2 in the ground 1 when the surface material 2 is buried in the ground under the ground 1 and forms a cavity 3, for example, the surface material 2 is supported by a prismatic box body 4. . The box body 4 is installed mainly below the surface material 2, in the air conditioner 7 or in the ground to form the cavity 3 communicating with the duct 6, but as shown in FIG. 3 and FIG. It may also serve to support the material 2. Since the surface material 2 may be supported only by the ground, the box body 4 does not necessarily have to support the surface material 2. The surface material 2 may be supported by the ground and the box body 4.

図3に示す表面材2の表面側を示す図4では表面材2に天然ゴム、もしくは合成ゴムの平板を使用した場合を示しているが、表面材2の材料は問われず、木材、プラスチック等も使用される。   FIG. 4 showing the surface side of the surface material 2 shown in FIG. 3 shows the case where a flat plate of natural rubber or synthetic rubber is used for the surface material 2, but the material of the surface material 2 is not limited, and wood, plastic, etc. Also used.

箱体4は図3に示すように地中の地盤に接する底板41と底板41の周囲を包囲する筒状の側壁42を持ち、側壁42の空調機7等、もしくはダクト6側の面には空調機7等に付属する管、もしくはダクト6が接続される接続口42aが形成される。底板41と側壁42は表面材2の平面形状に対応した平面形状をし、箱体4は四角柱状、五角柱状等の立体形状をする。側壁42は地盤の深さ方向には箱体4の底板41の上面が空調機7等、もしくはダクト6の底面以下に位置する深さを持つ。   As shown in FIG. 3, the box body 4 has a bottom plate 41 in contact with the ground in the ground and a cylindrical side wall 42 surrounding the bottom plate 41, and the side wall 42 has an air conditioner 7 or the like, or a surface on the duct 6 side. A connection port 42a to which the pipe attached to the air conditioner 7 or the duct 6 is connected is formed. The bottom plate 41 and the side wall 42 have a planar shape corresponding to the planar shape of the surface material 2, and the box body 4 has a three-dimensional shape such as a quadrangular prism shape or a pentagonal prism shape. The side wall 42 has such a depth that the upper surface of the bottom plate 41 of the box body 4 is located below the bottom surface of the air conditioner 7 or the duct 6 in the depth direction of the ground.

表面材2が設置される場所のグラウンド1の表面(表層)部分の材料には人工芝、天然芝、土、アンツーカー等が使用されるが、開口21からは例えば人工芝のゴムチップやこれらの破片、ごみ等が入り込む可能性がある。この開口21からの破片等の入り込みに備え、後述のように表面材2が箱体4に支持される場合、表面材2は箱体4から容易に取り外し自在になっており、表面材2の取り外しにより箱体4の底板41上に溜まった破片等を排除し、箱体4内を清掃することが可能になっている。   Artificial turf, natural turf, soil, antucar, etc. are used as the material of the surface (surface layer) of the ground 1 where the surface material 2 is installed. Debris, dust, etc. may get inside. When the surface material 2 is supported by the box body 4 as described later in preparation for the intrusion of debris or the like from the opening 21, the surface material 2 is easily removable from the box body 4 and It is possible to remove the debris and the like accumulated on the bottom plate 41 of the box body 4 by removing it and clean the inside of the box body 4.

またグラウンド1の上空に屋根架構がない場合には、表面材2の開口21から箱体4内に雨水が浸入することが想定され、屋根架構の有無に拘わらず、グラウンド1上への散水の水が浸入することも想定される。この水の浸入に備え、箱体4の底板41や側壁42の底面に近い部分に浸入水の排除のための排水管を接続し、箱体4に排水機能を持たせることも可能である。   When there is no roof frame above the ground 1, rainwater is assumed to enter the box 4 through the opening 21 of the surface material 2. Irrespective of the presence or absence of the roof frame, sprinkling water over the ground 1 is possible. Infiltration of water is also expected. In preparation for the infiltration of water, it is possible to connect a drain pipe for removing the infiltrated water to a portion of the box body 4 near the bottom plate 41 and the bottom surface of the side wall 42 so that the box body 4 has a drainage function.

図3は箱体4にダクト6が接続される場合の箱体4とダクト6の接続例を示しているが、ダクト6は側壁42の接続口42aに接続される。両者の接続方法は問われないが、図3では側壁42の接続口42a周りからダクト6側へ筒状の接続部42bを突設し、この接続部42bにダクト6を外接させ、接続している。図3ではまた、表面材2の開口21から落下する土砂等がダクト6内に入り込まないよう、接続口42aに網43やフィルターを固定している。   3 shows an example of connection between the box body 4 and the duct 6 when the duct 6 is connected to the box body 4, the duct 6 is connected to the connection port 42a of the side wall 42. Although the connection method of both is not limited, in FIG. 3, a cylindrical connecting portion 42b is provided so as to project from around the connecting opening 42a of the side wall 42 toward the duct 6, and the duct 6 is circumscribed and connected to the connecting portion 42b. There is. In FIG. 3, the net 43 and the filter are fixed to the connection port 42a so that earth and sand falling from the opening 21 of the surface material 2 does not enter the duct 6.

図3に示すように表面材2が箱体4に支持される場合、箱体4(側壁42)は表面材2を包囲するだけの平面積を持ち、側壁42の上部には少なくとも表面材2の周囲(縁)を支持する受け部44が形成される。受け部44は表面材2の周囲に沿って周回するように環状に形成される場合と、表面材2の周囲と周囲以外の部分を支持し得るよう、格子状に形成される場合がある。   When the surface material 2 is supported by the box body 4 as shown in FIG. 3, the box body 4 (side wall 42) has a flat area enough to surround the surface material 2, and at least the surface material 2 is provided above the side wall 42. A receiving portion 44 that supports the periphery (edge) of the is formed. The receiving portion 44 may be formed in an annular shape so as to circulate along the periphery of the surface material 2, or may be formed in a lattice shape so as to support the periphery of the surface material 2 and a portion other than the periphery.

箱体4が鋼材等により製作される場合、側壁42の上端部42cがグラウンド1の表面に露出することによるプレーへの支障が生じ得ることから、図3、図5では側壁42の上端部42cが地中に完全に埋設される深さに箱体4を設置している。   When the box body 4 is made of steel or the like, the upper end 42c of the side wall 42 may be exposed to the surface of the ground 1, which may interfere with play. The box body 4 is installed at a depth where it is completely buried in the ground.

箱体4の側壁42に受け部44が形成された場合に、表面材2が受け部44に載置されるだけでは表面材2を安定させて支持することができない場合には、表面材2は図4に示すように受け部44にボルト等のねじ45で固定される。   When the receiving portion 44 is formed on the side wall 42 of the box body 4 and the surface material 2 cannot be stably supported only by being placed on the receiving portion 44, the surface material 2 Is fixed to the receiving portion 44 with screws 45 such as bolts as shown in FIG.

但し、側壁42の受け部44より上の上端部42cを側壁42の内周側へ湾曲させるか、突出させる等により、対向する上端部42c、42cが表面材2の側面に密着し、表面材2の側面を中心側へ挟持し、表面材2を保持することができれば、ねじ45等による固定は必ずしも必要ではない。表面材2がねじ45で受け部44に固定される場合、表面材2の、平面上、受け部44に重なる領域にねじ45が挿通、または螺合する挿通孔22が形成される。   However, the upper end portion 42c of the side wall 42 above the receiving portion 44 is curved toward the inner peripheral side of the side wall 42, or is protruded. If the side surface of 2 is pinched to the center side and the surface material 2 can be held, the fixing by the screw 45 or the like is not always necessary. When the surface material 2 is fixed to the receiving portion 44 with the screw 45, the insertion hole 22 into which the screw 45 is inserted or screwed is formed in a region of the surface material 2 which overlaps the receiving portion 44 in a plane.

箱体4の表面側、及びダクト6にはダクト6を通じてグラウンド1上に放出される空調空気の冷気、または熱気の温度を保つための断熱材5が張り付けられる。   A heat insulating material 5 is attached to the front surface side of the box body 4 and the duct 6 for keeping the temperature of the cold air or the hot air of the conditioned air discharged onto the ground 1 through the duct 6.

図5はピッチャーズプレートの後方とピッチャーズマウンドの周囲の複数箇所に表面材2を配置した場合の表面材2と箱体4の埋設状態を示す。図6はピッチャーズプレート後方に配置された表面材2の箱体4への支持状態を示す。ここでは表面材2の周囲をプレー中の選手のスパイクから保護するためにゴム製の保護材2Aを表面材2の周囲に周回させて配置している。保護材2Aは地盤に支持されるだけのこともあるが、図6では箱体4の側壁42の上端部42cに保護材2Aを支持させている。保護材2Aは箱体4の外周面にフランジ状に形成される受け部に支持されることもある。   FIG. 5 shows the embedding state of the surface material 2 and the box body 4 when the surface material 2 is arranged at the rear of the pitchers plate and at a plurality of positions around the pitchers mound. FIG. 6 shows a state in which the surface material 2 arranged behind the pitchers plate is supported by the box body 4. Here, in order to protect the periphery of the surface material 2 from the spikes of the player who is playing, a rubber protective material 2A is arranged around the surface material 2 so as to circulate. Although the protective material 2A may only be supported by the ground, in FIG. 6, the protective material 2A is supported by the upper end portion 42c of the side wall 42 of the box body 4. The protective material 2A may be supported by a receiving portion formed in a flange shape on the outer peripheral surface of the box body 4.
