Description

本発明は、水道管が内部に挿通されており、前記水道管に設けられた量水器あるいは止水栓等の機器が収容される埋設ボックスに関する。 The present invention relates to a buried box in which a water pipe is inserted therein and a device such as a water meter or a water stopcock provided in the water pipe is housed.

従来から、水道管が内部に挿通されており、前記水道管に設けられた量水器あるいは止水栓等の機器が収容される埋設ボックスが提案されている。また、このような埋設ボックスのうち、特に寒冷地で使用されるものには、断熱性能を有するものも種々提案されている。 Conventionally, a buried box has been proposed in which a water pipe is inserted inside and a device such as a water meter or a water stopcock provided in the water pipe is housed. Further, among such buried boxes, various ones having heat insulating performance have been proposed especially for those used in cold regions.

例えば特許文献1には、メーターボックスの蓋体の裏面に、発泡スチロール等の保温プレート材(断熱部)が取り付けられている構成が開示されている。 For example, Patent Document 1 discloses a configuration in which a heat insulating plate material (heat insulating portion) such as Styrofoam is attached to the back surface of a lid of a meter box.

特開2005−9165号公報Japanese Unexamined Patent Publication No. 2005-9165

しかしながら、上記特許文献1のように蓋体の裏面に保温材を取り付けた場合にも、閉じた蓋体と筐体との隙間から外部の冷気が筐体内に進入してしまい、保温性を保つのが困難であった。このように、筐体内に寒冷地の冷気が進入すると、水道管が凍結してしまう場合もある。 However, even when the heat insulating material is attached to the back surface of the lid as in Patent Document 1, external cold air enters the housing through the gap between the closed lid and the housing, and the heat retaining property is maintained. Was difficult. In this way, when cold air from a cold region enters the housing, the water pipe may freeze.

そこで本発明は、蓋体と筐体との隙間から筐体内に冷気が進入することを防止することができる埋設ボックスを提供することを目的とする。 Therefore, an object of the present invention is to provide an embedded box capable of preventing cold air from entering the housing through a gap between the lid and the housing.

本発明は、水道管が内部に挿通される埋設ボックスであって、上面に開口部が設けられた筐体と、前記開口部を開放又は遮蔽する蓋体と、を備え、前記開口部を遮蔽した状態の前記蓋体における前記水道管に臨む面には断熱部が形成されており、前記断熱部における外周縁部には、環状のシール部材が取り付けられており、前記蓋体が前記筐体の開口部を遮蔽した状態で、前記シール部材が前記開口部の開口縁部に沿って前記筐体の内壁面に当接していることを特徴とする埋設ボックスである。 The present invention is an embedded box through which a water pipe is inserted, and includes a housing having an opening on the upper surface and a lid for opening or shielding the opening, and shielding the opening. A heat insulating portion is formed on the surface of the lid body in the state of being facing the water pipe, and an annular sealing member is attached to the outer peripheral edge portion of the heat insulating portion, and the lid body is the housing. The embedded box is characterized in that the sealing member is in contact with the inner wall surface of the housing along the opening edge of the opening while the opening of the opening is shielded.

かかる構成にあっては、前記シール部材が前記筐体の内壁面に当接することによって、筐体と蓋体との隙間から冷気が前記筐体内に進入することを阻止することができる。また、前記シール部材は、前記断熱部に取り付けられているため、前記シール部材自体が、前記蓋体の上面部から伝わる冷温で冷えてしまうことも抑制できる。したがって、シール部材を介して筐体内が冷えてしまうことも抑制でき、水道管の凍結を効果的に防止することができる。 In such a configuration, when the sealing member comes into contact with the inner wall surface of the housing, it is possible to prevent cold air from entering the housing through the gap between the housing and the lid. Further, since the seal member is attached to the heat insulating portion, it is possible to prevent the seal member itself from being cooled by the cold temperature transmitted from the upper surface portion of the lid body. Therefore, it is possible to prevent the inside of the housing from being cooled through the seal member, and it is possible to effectively prevent the water pipe from freezing.

また、前記断熱部の外周縁部には、前記シール部材の少なくとも一部が内嵌するシール部材取付用凹部が設けられている構成が提案される。 Further, it is proposed that the outer peripheral edge portion of the heat insulating portion is provided with a sealing member mounting recess in which at least a part of the sealing member is fitted.

かかる構成とすることにより、前記シール部材の少なくとも一部が前記断熱部で囲われるため、前記シール部材が冷気に触れる露出面積を小さくすることができる。したがって、前記シール部材が過剰に冷えることをより一層効果的に防止できる。また、前記シール部材が前記断熱部に確実に保持されることとなるため、前記蓋体を開閉した時に前記シール部材が前記断熱部から脱落してしまうことを抑制することができる。 With such a configuration, since at least a part of the seal member is surrounded by the heat insulating portion, the exposed area where the seal member comes into contact with cold air can be reduced. Therefore, it is possible to more effectively prevent the sealing member from being excessively cooled. Further, since the seal member is surely held by the heat insulating portion, it is possible to prevent the seal member from falling off from the heat insulating portion when the lid is opened and closed.

さらに、前記筐体の内壁面には、前記蓋体が前記筐体の開口部を遮蔽した状態で前記蓋体を支持する支持段部が形成されており、前記蓋体が前記筐体の開口部を遮蔽した状態で、前記シール部材は、前記筐体の前記支持段部よりも下方の前記内壁面に当接している構成が提案される。 Further, a support step portion for supporting the lid body is formed on the inner wall surface of the housing in a state where the lid body shields the opening of the housing, and the lid body opens the housing. It is proposed that the seal member is in contact with the inner wall surface below the support step portion of the housing while the portion is shielded.

かかる構成にあっては、前記蓋体と前記筐体との間の隙間から進入するゴミ等はまず前記支持段部に堆積する。すなわち、前記シール部材は、前記支持段部よりも下方に配置されているため、前記シール部材上にゴミ等が溜まってしまうことが抑制される。したがって、蓋体を繰り返し開閉させた際も、前記シール部材と前記蓋体との間にゴミ等が噛み込んでしまう、といった問題も生じにくい。 In such a configuration, dust and the like entering through the gap between the lid and the housing are first deposited on the support step portion. That is, since the seal member is arranged below the support step portion, it is possible to prevent dust and the like from accumulating on the seal member. Therefore, even when the lid body is repeatedly opened and closed, it is unlikely that dust or the like will get caught between the seal member and the lid body.

また、前記シール部材は、前記断熱部に取り付けられる本体部と、前記蓋体が前記筐体の開口部を遮蔽した状態で前記本体部から前記筐体の内壁面に向かう方向に突き出されている突出部と、を備え、前記蓋体が前記筐体の開口部を遮蔽した状態で、前記突出部の先端部が前記筐体の内壁面に当接しており、前記突出部は、前記先端部側に向かうに従って厚みが薄くなる形状であることが望ましい。 Further, the seal member is projected from the main body portion toward the inner wall surface of the housing in a state where the main body portion attached to the heat insulating portion and the lid body shield the opening of the housing. A protruding portion is provided, and the tip portion of the protruding portion is in contact with the inner wall surface of the housing in a state where the lid body shields the opening of the housing, and the protruding portion is the tip portion. It is desirable that the shape becomes thinner toward the side.

かかる構成とすることにより、前記先端部が、より柔軟に前記筐体の内壁面に当接することになるため、蓋体と筐体との間に隙間が生じにくくなって冷気の進入を効果的に防止することができる。 With such a configuration, the tip portion more flexibly abuts on the inner wall surface of the housing, so that a gap is less likely to occur between the lid and the housing, and cold air can effectively enter. Can be prevented.

さらに、前記シール部材は、前記断熱部に取り付けられる本体部と、前記蓋体が前記筐体の開口部を遮蔽した状態で前記本体部から前記筐体の内壁面に向かう方向に突き出されている突出部と、を備え、前記蓋体が前記筐体の開口部を遮蔽した状態で、前記突出部の先端部が前記筐体の内壁面に当接しており、前記突出部の基端部には、他の部位より厚みが薄い薄肉部が形成されていることが望ましい。 Further, the seal member is projected from the main body portion to the inner wall surface of the housing in a state where the main body portion attached to the heat insulating portion and the lid body shield the opening of the housing. With a protrusion, the tip of the protrusion is in contact with the inner wall surface of the housing in a state where the lid shields the opening of the housing, and the base end of the protrusion is provided. It is desirable that a thin portion having a thickness thinner than that of other portions is formed.

かかる構成にあっては、前記突出部が前記薄肉部で柔軟に屈曲することになるため、前記突出部がより一層柔軟に前記筐体の内壁面に当接することになる。したがって、蓋体と筐体との間に隙間が生じにくくなって冷気の進入を効果的に防止することができる。 In such a configuration, the protruding portion flexibly bends at the thin-walled portion, so that the protruding portion more flexibly abuts on the inner wall surface of the housing. Therefore, a gap is less likely to be generated between the lid and the housing, and the intrusion of cold air can be effectively prevented.

本発明の埋設ボックスは、前記筐体と前記蓋体との隙間から冷気が筐体内に進入することを防止できる効果がある。 The embedded box of the present invention has an effect of preventing cold air from entering the housing through the gap between the housing and the lid.

以下、本発明の埋設ボックスを具体化した実施例を詳細に説明する。なお、本発明は、下記に示す実施例に限定されることはなく、適宜設計変更が可能である。 Hereinafter, examples in which the buried box of the present invention is embodied will be described in detail. The present invention is not limited to the examples shown below, and the design can be changed as appropriate.

〔実施例〕
図1に示すように、埋設ボックス1は、上面に開口部11が設けられた略直方体箱形状の筐体10を備えている。そして、筐体10の内部は、内壁面12によって内部空間Sが画定されている。また、筐体10は、対向する2壁面にそれぞれ水道管Pが挿通される水道管挿通孔13,13が設けられている。
〔Example〕
As shown in FIG. 1, the embedded box 1 includes a substantially rectangular parallelepiped box-shaped housing 10 having an opening 11 on the upper surface. An internal space S is defined by an inner wall surface 12 inside the housing 10. Further, the housing 10 is provided with water pipe insertion holes 13 and 13 into which the water pipe P is inserted on the two facing wall surfaces, respectively.

さらに、筐体10の内壁面12における開口部11の近傍には、当該開口部11の開口縁に沿って形成された支持段部15が形成されている。なお、支持段部15は、後述する蓋体20が筐体10の開口部11を遮蔽した状態で蓋体20を下から支持する機能を有している。 Further, in the vicinity of the opening 11 on the inner wall surface 12 of the housing 10, a support step portion 15 formed along the opening edge of the opening 11 is formed. The support step portion 15 has a function of supporting the lid body 20 from below with the lid body 20 described later shielding the opening 11 of the housing 10.

また、埋設ボックス1は、板形状の蓋体20を備えている。具体的には、蓋体20は筐体10の開口部11の近傍に軸支されており、筐体10の開口部11を開放又は遮蔽する機能を有している。そして、図3(b)に示すように、蓋体20が筐体10の開口部11を遮蔽した状態にあっては、蓋体20の外周縁の下端部21が筐体10の支持段部15に上から当接する。 Further, the buried box 1 includes a plate-shaped lid 20. Specifically, the lid 20 is axially supported in the vicinity of the opening 11 of the housing 10, and has a function of opening or shielding the opening 11 of the housing 10. Then, as shown in FIG. 3B, when the lid body 20 shields the opening 11 of the housing 10, the lower end 21 of the outer peripheral edge of the lid 20 is the support step portion of the housing 10. It comes into contact with 15 from above.

また、図1に示すように、蓋体20は開口部11を遮蔽した状態で水道管P側に臨む面である裏面22を有しており、さらにこの裏面22の中央には、断熱機能を有した略直方体形状の断熱部30を有している。なお、断熱部30は、例えば板形状の断熱部材を裏面22に固定することによって構成するようにしてもよいし、蓋体本体部分と一体成形して構成するようにしてもよい。 Further, as shown in FIG. 1, the lid 20 has a back surface 22 which faces the water pipe P side in a state where the opening 11 is shielded, and further, a heat insulating function is provided in the center of the back surface 22. It has a substantially rectangular parallelepiped heat insulating portion 30. The heat insulating portion 30 may be formed by, for example, fixing a plate-shaped heat insulating member to the back surface 22, or may be integrally molded with the lid body portion.

次に、本発明の要部について説明する。
図3(a)に示すように、前記蓋体20における断熱部30の外周縁部31には、凹陥状のシール部材取付用凹部32が外周縁部31を1周する態様で設けられている。したがって、蓋体20が筐体10の開口部11を遮蔽した状態では、シール部材取付用凹部32は筐体10の内壁面12に対向することとなる。
Next, a main part of the present invention will be described.
As shown in FIG. 3A, the outer peripheral edge portion 31 of the heat insulating portion 30 in the lid body 20 is provided with a concave portion 32 for attaching a sealing member in a concave shape so as to go around the outer peripheral edge portion 31 once. .. Therefore, when the lid 20 shields the opening 11 of the housing 10, the sealing member mounting recess 32 faces the inner wall surface 12 of the housing 10.

また、図1に示すように、シール部材取付用凹部32にはシール部材40が取り付けられる。 Further, as shown in FIG. 1, the seal member 40 is attached to the seal member attachment recess 32.

さらに詳述すると、図2(a)に示すように、シール部材40は、略四角環形状をなし、図2(b)に示すように、シール部材取付用凹部32に内嵌可能な形状の本体部41を備えている。また、本体部41の外周面には、外側に向かって突出する突出部42が設けられている。 More specifically, as shown in FIG. 2A, the seal member 40 has a substantially square ring shape, and as shown in FIG. 2B, the seal member 40 has a shape that can be fitted into the seal member mounting recess 32. The main body 41 is provided. Further, a protruding portion 42 projecting outward is provided on the outer peripheral surface of the main body portion 41.

また、図2(b)に示すように、突出部42は、先端部43に向かうに従って厚みが薄くなる形状を有している。さらに、突出部42の基端部には、他の部位よりも厚みが薄い薄肉部45が形成されている。 Further, as shown in FIG. 2B, the protruding portion 42 has a shape in which the thickness decreases toward the tip portion 43. Further, a thin portion 45 having a thickness thinner than that of other portions is formed at the base end portion of the protruding portion 42.

そして、図3(b)に示すように、シール部材40の本体部41がシール部材取付用凹部32に内嵌されてシール部材40が断熱部30に取り付けられると、蓋体20が筐体10の開口部11を遮蔽した状態で、突出部42は、本体部41から筐体10の内壁面12に向かって突出することになる。 Then, as shown in FIG. 3B, when the main body 41 of the seal member 40 is internally fitted in the seal member mounting recess 32 and the seal member 40 is attached to the heat insulating portion 30, the lid 20 is attached to the housing 10. The protruding portion 42 projects from the main body portion 41 toward the inner wall surface 12 of the housing 10 in a state where the opening portion 11 is shielded.

上記した構成にあって、蓋体20を閉じて筐体10の開口部11を遮蔽した状態とすると、図3(b)に示すように、蓋体20は筐体10の支持段部15に支持されると共に、シール部材40の先端部43は、開口部11の開口縁部に沿って筐体10の内壁面12に当接する。 In the above configuration, assuming that the lid 20 is closed to shield the opening 11 of the housing 10, the lid 20 is attached to the support step 15 of the housing 10 as shown in FIG. 3 (b). While being supported, the tip 43 of the seal member 40 comes into contact with the inner wall surface 12 of the housing 10 along the opening edge of the opening 11.

したがって、蓋体20が筐体10の開口部11を遮蔽した状態では、シール部材40によって埋設ボックス1の外部と内部空間Sとが遮断されるため、外部の冷気が埋設ボックス1の内部空間Sに進入することを防止できる。 Therefore, in a state where the lid 20 shields the opening 11 of the housing 10, the seal member 40 blocks the outside of the buried box 1 from the internal space S, so that the outside cold air enters the internal space S of the buried box 1. Can be prevented from entering.

また、シール部材40の本体部41が断熱部30に囲われているため、シール部材40における外気に触れる露出面積が小さくなり、シール部材40自体が冷気によって冷えてしまうことも抑制されている。また、このように、シール部材40が断熱部30に嵌合していると、蓋体20が繰り返し開閉された場合にも、シール部材40が断熱部30から脱落してしまうことが抑制される。 Further, since the main body 41 of the seal member 40 is surrounded by the heat insulating portion 30, the exposed area of the seal member 40 that comes into contact with the outside air is reduced, and the seal member 40 itself is prevented from being cooled by the cold air. Further, when the seal member 40 is fitted to the heat insulating portion 30 in this way, it is possible to prevent the seal member 40 from falling off from the heat insulating portion 30 even when the lid 20 is repeatedly opened and closed. ..

また、シール部材40の突出部42は、先端部43に向かうに従って厚みが薄くなる形状であるため、先端部43がより柔軟に筐体10の内壁面12に当接する。したがって、シール部材40のシール性能(内部空間Sと外部との遮断性能)をより良好なものとすることができる。 Further, since the protruding portion 42 of the seal member 40 has a shape that becomes thinner toward the tip portion 43, the tip portion 43 more flexibly contacts the inner wall surface 12 of the housing 10. Therefore, the sealing performance of the sealing member 40 (the blocking performance between the internal space S and the outside) can be improved.

さらに、シール部材40には薄肉部45が形成されているため、突出部42は本体部41に対してより柔軟に屈曲することができる。このため、シール部材40のシール性能が大幅に向上する。 Further, since the seal member 40 is formed with the thin-walled portion 45, the protruding portion 42 can be bent more flexibly with respect to the main body portion 41. Therefore, the sealing performance of the sealing member 40 is significantly improved.

なお、突出部42は単一のシール部材40において複数設けられていても構わない。 A plurality of projecting portions 42 may be provided in a single seal member 40.

また、シール部材40の突出部42の先端部43は、筐体10における支持段部15よりも下方の内壁面12に当接している。ここで、埋設ボックス1の使用環境によっては、筐体10と蓋体20との隙間からゴミ等が進入することがあるところ、このようなゴミ等はまず支持段部15に堆積することになる。このため、シール部材40上にゴミ等が堆積することがなくなり、シール部材40と蓋体20と間にゴミ等が噛み込んでしまう、といった問題も生じにくい。 Further, the tip portion 43 of the protruding portion 42 of the seal member 40 is in contact with the inner wall surface 12 below the support step portion 15 in the housing 10. Here, depending on the usage environment of the buried box 1, dust or the like may enter through the gap between the housing 10 and the lid 20, and such dust or the like first accumulates on the support step portion 15. .. Therefore, dust or the like does not accumulate on the seal member 40, and the problem that dust or the like gets caught between the seal member 40 and the lid 20 is unlikely to occur.

〔変形例1〕
図4(a)に示すように、本発明は、シール部材取付用凹部32が設けられることなく、断熱部30の外周縁部31にシール部材50が取り付けられている構成としてもよい。なお、このように本発明においてシール部材取付用凹部32は必須のものではないが、蓋体20は頻繁に開閉されるため、シール部材50が断熱部30から容易に脱落しない構成であることが望ましい。
[Modification 1]
As shown in FIG. 4A, the present invention may have a configuration in which the seal member 50 is attached to the outer peripheral edge portion 31 of the heat insulating portion 30 without providing the seal member attachment recess 32. As described above, although the sealing member mounting recess 32 is not essential in the present invention, the lid body 20 is frequently opened and closed, so that the sealing member 50 does not easily fall off from the heat insulating portion 30. desirable.

〔変形例2〕
また、図4(b)に示すように、本発明は、シール部材50が支持段部15の形成されない筐体60の内壁面12に当接している構成であってもよい。かかる構成にあっても、冷気が筐体60内に進入することを防止できる。
[Modification 2]
Further, as shown in FIG. 4B, the present invention may have a configuration in which the seal member 50 is in contact with the inner wall surface 12 of the housing 60 in which the support step portion 15 is not formed. Even with such a configuration, it is possible to prevent cold air from entering the housing 60.

上記した実施例等の各部の寸法形状は適宜自由に選択可能である。 The dimensions and shape of each part of the above-described embodiment can be freely selected as appropriate.

また、筐体10,60や蓋体20は合成樹脂材料によって構成されていることが望ましい。また、断熱部30の材料は、断熱性能を有するものであれば特に限定されないが、コストや製造容易性の観点から例えば発泡スチロール等の発泡樹脂材料によって構成されていることが望ましい。また、シール部材40,50はシール性能を向上させるべく可撓性の合成樹脂材料(例えばゴム材料)で構成されていることが望ましい。 Further, it is desirable that the housings 10 and 60 and the lid 20 are made of a synthetic resin material. The material of the heat insulating portion 30 is not particularly limited as long as it has heat insulating performance, but it is desirable that the heat insulating portion 30 is made of a foamed resin material such as styrofoam from the viewpoint of cost and ease of manufacture. Further, it is desirable that the sealing members 40 and 50 are made of a flexible synthetic resin material (for example, a rubber material) in order to improve the sealing performance.
