Description

本発明は、建物の壁面や天井に設けられる点検口等の点検口用枠材に関する。 The present invention relates to an inspection port frame material such as an inspection port provided on a wall surface or ceiling of a building.

建物には、給排水設備あるいは電気設備として、配管や配線が壁や天井の裏側に配設されている。そして、定期的なメンテナンス（検査、部分補修、など）のために点検口を壁や天井に設けるのが一般的である。 In the building, piping and wiring are disposed on the back side of the wall or ceiling as water supply / drainage equipment or electrical equipment. In general, an inspection port is provided on a wall or ceiling for regular maintenance (inspection, partial repair, etc.).

例えば、壁面に設けられる簡易な点検口用の枠材として、図６に示すように、略Ｕ字状に溝形成された枠材５１を点検用に開口された壁面を塞ぐ蓋材５２の周囲に配置し、壁の内側に位置する下地材５３にビス５４で固定することが従来から行われていた。
しかし、このような枠材５１は、（１）略Ｕ字状に形成された枠材５１の内部にビス５３の頭部が見えるため美観上好ましくなく、かつ（２）蓋材５２を外すためには、ビス５４と枠材５１の両方を取り外す必要がある問題点があった。 For example, as a frame material for a simple inspection port provided on the wall surface, as shown in FIG. 6, a frame material 51 formed with a groove in a substantially U shape is surrounded by a cover material 52 that closes the wall surface opened for inspection. It has been conventionally performed to be fixed to the base material 53 located inside the wall with screws 54.
However, such a frame member 51 is (1) unfavorable for aesthetics because the head of the screw 53 can be seen inside the substantially U-shaped frame member 51, and (2) for removing the lid member 52. Has a problem that it is necessary to remove both the screw 54 and the frame member 51.

そこで、蓋材を外すことなく蓋材を容易に取り外すことができる点検口用枠材が種々提案されている（例えば、特許文献１，２）。 Accordingly, various inspection port frame materials that can easily remove the lid material without removing the lid material have been proposed (for example, Patent Documents 1 and 2).

特許文献１の「開口部形成用の縁材」は、開口部の周縁部分に取り付けられる合成樹脂製の縁材であって、図７に示すように、取付部に釘着される取付片６３の両側に側片６５，６６を対向して突設し、該側片６５，６６間に溝部６７を形成するとともに、一方の側片の先端縁部材には、その外方に向け、天井板、壁板あるいは床板等の端縁部分を覆う覆片６１を連設し、該一方の側片の先端縁部分には、前記溝部６７の開放部を遮蔽する遮蔽片部７３と蓋板の端縁部分を覆う受片部７４とを一体化してなる可動片７０を蝶番部７１を介して一体に設け、該可動片７０は、他方の側片に設けられている第１の係合部７５と可動片７０に設けられている第２の係合部７６との係合によって、遮蔽片部７３が開放部を遮蔽しかつ受片部７４が蓋板の端縁部分を覆った状態で保持されるようにしたものである。 The “edge material for forming an opening” in Patent Document 1 is an edge material made of synthetic resin that is attached to the peripheral portion of the opening, and as shown in FIG. 7, an attachment piece 63 that is nailed to the attachment portion. The side pieces 65 and 66 are provided so as to be opposed to each other and a groove 67 is formed between the side pieces 65 and 66, and the tip edge member of one side piece is directed outwardly from the ceiling plate. A cover piece 61 that covers an edge portion such as a wall plate or a floor plate is continuously provided, and a shield piece portion 73 that shields an open portion of the groove portion 67 and an end of the lid plate are provided at the tip edge portion of the one side piece. A movable piece 70 formed integrally with the receiving piece portion 74 covering the edge portion is integrally provided via a hinge portion 71, and the movable piece 70 is a first engagement portion 75 provided on the other side piece. And the second engaging portion 76 provided on the movable piece 70, the shielding piece portion 73 shields the open portion and the receiving piece portion 74 is the lid plate. It is obtained so as to be held in a state of covering the edge portions.

特許文献２の「点検口の枠」は、図８に示すように、下地材などの取付け部材に取り付ける取付け板８１と、この取付け板から壁板などの板材の厚み分突設している支持板８２と、この支持板の端部に直交状態に設けてあり、一端側では上記取付け板と共に上記板材を挟持し、他端部は係合部を設けてある保持板８３と、この保持板の一端部にセルフヒンジ８４により回動可能に連設し、上記保持板側の面に上記係合部と係脱可能の係止突部を突設し、点検口蓋の外周部を覆うカバー板８５とを具備するものである。 As shown in FIG. 8, the “inspection frame” of Patent Document 2 has a mounting plate 81 attached to a mounting member such as a base material, and a support projecting from the mounting plate by the thickness of a plate material such as a wall plate. A holding plate 83 provided perpendicularly to the end of the plate 82 and the support plate, sandwiching the plate material together with the mounting plate on one end side, and having an engaging portion on the other end, and the holding plate A cover plate that is connected to one end of the inspection plate so as to be rotatable by a self hinge 84, a locking projection that can be engaged with and disengaged from the engagement portion is provided on the surface of the holding plate, and covers the outer peripheral portion of the inspection opening 85.

実開昭６１−２０３９４３号公報、「開口部形成用の縁材」Japanese Utility Model Publication No. 61-203943, “Edge material for forming openings” 実開昭６０−４１４３４号公報、「点検口の枠」Japanese Utility Model Publication No. 60-41434, “Frame of Inspection Port”

しかし、上述した従来の点検口用枠材には、以下の問題点があった。 However, the above-described conventional inspection frame material has the following problems.

（１）蓋板の縁部を支持する可動片（可動片又はカバー板）が、ヒンジ部（蝶番部又はセルフヒンジ）を中心に開閉するようになっているが、ヒンジ部に可撓性がほとんどない。そのため、可動片を開放又は係合させるためには、係止部自体（第１の係合部２と第２の係合部、又は係合突部と係止片）を変形させる必要がある。
そのため、係止部の係合を強くすると、可動片の開放又は係合の際に、係止部が変形して破損したり、取付部に釘着されたビス部に無理な力が作用してビスが外れてしまうことがあった。
また、逆に係止部の係合を弱くすると、不用意に可動片が開放してしまい、蓋板が落下することがあった。 (1) The movable piece (movable piece or cover plate) that supports the edge of the lid plate opens and closes around the hinge (hinge or self-hinge), but the hinge is flexible. rare. Therefore, in order to open or engage the movable piece, it is necessary to deform the locking portion itself (the first engaging portion 2 and the second engaging portion, or the engaging protrusion and the locking piece). .
Therefore, if the engagement of the locking part is strengthened, the locking part is deformed and damaged when the movable piece is released or engaged, or an unreasonable force acts on the screw part nailed to the mounting part. The screw may come off.
On the other hand, if the engagement of the locking portion is weakened, the movable piece may be inadvertently opened and the lid plate may fall.

（２）また、ヒンジ部に可撓性がほとんどないにもかかわらず、同一部材で一体成形されているので、可動片の開放又は係合の際に、係止部が変形して外れるまでヒンジ部に係止部を支点とするせん断力が作用する。
そのため、可動片の開放又は係合を繰り返すと、ヒンジ部が疲労して破損することがあった。 (2) Further, although the hinge part has almost no flexibility, the hinge part is integrally formed with the same member. Therefore, when the movable piece is released or engaged, the hinge part is deformed and detached until it is detached. A shearing force with the locking portion as a fulcrum acts on the portion.
Therefore, when the opening or engagement of the movable piece is repeated, the hinge portion may be fatigued and damaged.

（３）特許文献１の構成では、点検口枠が形成された場合に壁の表面に現れる額縁体は、覆片と、受け片部および遮蔽片部からなる可動片により構成されるため、幅広の点検口額縁が形成される。
そのため、点検口が太い額縁で囲われた状態に見え、建物の美観上、なるべく点検口を目立たないようにしたいという要望を満たせない問題点があった。 (3) In the configuration of Patent Document 1, the frame body that appears on the surface of the wall when the inspection port frame is formed is composed of a cover piece, and a movable piece composed of a receiving piece portion and a shielding piece portion. The inspection port picture frame is formed.
For this reason, the inspection port appears to be surrounded by a thick frame, and there has been a problem that the request to make the inspection port as inconspicuous as possible is not satisfied in view of the building.

（４）また、特許文献２の構成では、支持板の頂部から延出した保持板の先端にセルフヒンジを介してカバー板を取り付けるため、保持板とカバー板が重なりあって点検口の額縁となる部分の厚さが相当厚くなるという問題があった。 (4) Moreover, in the structure of patent document 2, in order to attach a cover plate to the front-end | tip of the holding plate extended from the top part of the support plate via the self hinge, the holding plate and the cover plate overlap and the frame of the inspection port There is a problem that the thickness of the portion becomes considerably thick.

（５）さらに、通常の施工では、下地材に壁板を取り付けた後に、壁板に所定の開口を設けて枠材を取り付けるのに対し、特許文献２の構成では、点検口の取付け板を下地材に取り付けた後でなければ壁板の取り付けができないため、施工上の不具合が生じる問題点があった。 (5) Furthermore, in normal construction, after attaching the wall plate to the base material, a predetermined opening is provided in the wall plate and the frame material is attached. Since the wall plate cannot be attached unless it is attached to the base material, there has been a problem that causes problems in construction.

本発明はかかる問題点を解決するために創案されたものである。すなわち、本発明の目的は、（１）係止部の係合を十分強くしても、係止部自体を変形させることなく、開放又は係合を容易かつ確実に行うことができ、（２）開放又は係合を繰り返しても、疲労により破損する部分がなく、（３）点検口を囲む枠部の幅を狭くして目立たなくでき、（４）枠部の厚さを薄くでき、（５）下地材に壁板を取り付けた後に、壁板に開口を設けて、枠材を取り付けることができる点検口用枠材を提供することにある。 The present invention has been made to solve such problems. That is, the object of the present invention is as follows: (1) Even if the engagement of the locking part is sufficiently strong, the opening or engagement can be easily and reliably performed without deforming the locking part itself, (2 ) Even if it is repeatedly released or engaged, there is no portion damaged by fatigue, (3) the width of the frame surrounding the inspection port can be made inconspicuous, (4) the thickness of the frame can be reduced, ( 5) To provide a frame material for an inspection port that can be provided with an opening in the wall plate after the wall plate is attached to the base material, to which the frame material can be attached.

図３は図２の点検口用枠材の作動説明図である。この図において、（Ａ）は第２係合部２２が第１係合部１６に係合した状態、（Ｃ）は第２係合部２２が第１係合部１６から完全に外れた状態、（Ｂ）はその中間状態である。 FIG. 3 is an operation explanatory view of the inspection port frame member of FIG. In this figure, (A) is a state in which the second engaging portion 22 is engaged with the first engaging portion 16, and (C) is a state in which the second engaging portion 22 is completely detached from the first engaging portion 16. , (B) is the intermediate state.

図３（Ａ）の係合状態において、第２係合部２２の正面側平面が第１係合部１６の背面側平面と十分広い面積で係合している。また、可撓性のヒンジ部２４は、係合状態で第２係合部２２を第１係合部側に付勢している。
従って、（Ａ）の係合状態において、額縁部２０を室内側（この図で上向き）に強く引いても、第２係合部２２と第１係合部１６の係合は容易には外れず、蓋板４を確実に固定し続ける。これにより、不用意に開放して蓋板蓋板４を落下することを防止することができる。 3A, the front side plane of the second engagement portion 22 is engaged with the back side plane of the first engagement portion 16 in a sufficiently wide area. Further, the flexible hinge portion 24 urges the second engagement portion 22 toward the first engagement portion in the engaged state.
Therefore, in the engaged state of (A), even if the frame portion 20 is pulled strongly indoors (upward in this figure), the engagement between the second engagement portion 22 and the first engagement portion 16 can be easily removed. This prevents the cover plate 4 from being securely fixed. Accordingly, it is possible to prevent the lid plate cover plate 4 from being accidentally opened and falling.

図３（Ｂ）の中間状態において、額縁部２０を隙間内で蓋材４側に移動することにより、第２係合部２２と第１係合部１６の係合が外れる。この状態で、更に額縁部２０を室内側（この図で上向き）に軽く引くことで、係止部（第１係合部１６と第２係合部２２）自体を変形させることなく、容易かつ確実に額縁部２０を開放することができる。
また、逆に開放状態から係合状態にする際には、額縁部２０を壁側（この図で下向き）に軽く押し込むことで、第２係合部２２の背面側円弧面が第１係合部１６の正面側円弧面で案内されて、自動的に第１係合部１６と第２係合部２２が係合状態に戻り、かつヒンジ部２４の付勢力で係合状態をそのまま保持することができる。 In the intermediate state of FIG. 3 (B), the frame portion 20 is moved to the lid member 4 side within the gap, whereby the second engagement portion 22 and the first engagement portion 16 are disengaged. In this state, by further pulling the frame portion 20 lightly toward the indoor side (upward in this figure), the locking portions (the first engaging portion 16 and the second engaging portion 22) themselves can be easily and without being deformed. The frame portion 20 can be reliably opened.
On the contrary, when changing from the open state to the engaged state, the back side arc surface of the second engaging portion 22 is first engaged by lightly pushing the frame portion 20 toward the wall side (downward in this figure). The first engaging portion 16 and the second engaging portion 22 are automatically returned to the engaged state while being guided by the front-side arc surface of the portion 16, and the engaged state is maintained as it is by the biasing force of the hinge portion 24. be able to.

図３（Ｃ）の完全に外れた状態では、ヒンジ部２４の弾性により額縁部２０は開放位置に移動するので、蓋材４の脱着を容易に行うことができる。 3C, the frame portion 20 moves to the open position due to the elasticity of the hinge portion 24, so that the lid member 4 can be easily attached and detached.

さらに図２及び図３の第１実施形態では、ヒンジ部２４の一端（図で右端）は仕切り部１４の室内側端部の壁部材側頂部に一体成形で固定され、中間部は壁部材側頂部から延出し、蓋材側に湾曲して折れ目なく伸延され、額縁部２０の壁部材側２０ａに連接されている。
この構成により、見切り部１８が額縁部２０で覆い隠された状態となり、かつ見切り部側に延出した後に折り返すことによって、見切り部１８とヒンジ部２４との間に目地が形成され、あたかも別体の額縁を嵌め込んだように見える。 Further, in the first embodiment of FIGS. 2 and 3, one end (right end in the figure) of the hinge portion 24 is fixed to the top of the wall member side of the indoor side end portion of the partition portion 14 by integral molding, and the intermediate portion is on the wall member side. It extends from the top, curves to the lid material side, extends without a fold, and is connected to the wall member side 20a of the frame portion 20.
With this configuration, the parting part 18 is covered with the frame part 20, and the joint part is formed between the parting part 18 and the hinge part 24 by folding back after extending to the parting part side. It looks like the frame of the body is fitted.

上述した本発明の構成によれば、固定枠部１０と額縁部２０が可撓性のヒンジ部２４を介して連結しているので、第１係合部１６と第２係合部２２の係合を十分強くしても、ヒンジ部２４の変形により、係止部自体を変形させることなく、開放又は係合を容易かつ確実に行うことができる。
また、開放又は係合を繰り返しても、ヒンジ部２４は可撓性を有するので、変形を繰り返すことができ、疲労により破損することがない。
また、固定枠部１０はＬ字型であり、額縁部２０は平板状であるため、室内側から見える部分は、額縁部２０のみであり、これを必要最小限の幅にすることで、点検口を囲む枠部の幅を狭くして目立たなくできる。
また、室内側から見える枠部の厚さは、見切り部１８とヒンジ部端部であり、これらを必要最小限の厚さにすることで、枠部の厚さを薄くできる。
さらに、固定枠部１０はＬ字型であり、壁部材５側に突出した部分がないため、下地材４に壁板（壁部材５）を取り付けた後に、通常の施工と同様に、壁板に開口を設けて、固定枠部１０を取り付けることができる。 According to the configuration of the present invention described above, since the fixed frame portion 10 and the frame portion 20 are connected via the flexible hinge portion 24, the engagement between the first engagement portion 16 and the second engagement portion 22 is achieved. Even if the joint is sufficiently strong, the hinge portion 24 can be easily and reliably released or engaged without deforming the locking portion itself due to the deformation of the hinge portion 24.
Moreover, even if it repeats opening or engaging, since the hinge part 24 has flexibility, it can repeat a deformation | transformation and is not damaged by fatigue.
In addition, since the fixed frame portion 10 is L-shaped and the frame portion 20 is flat, the portion visible from the indoor side is only the frame portion 20, and inspection is performed by making this the minimum necessary width. The width of the frame surrounding the mouth can be made inconspicuous by reducing the width.
Moreover, the thickness of the frame part seen from the indoor side is the parting part 18 and the hinge part end part, and the thickness of the frame part can be reduced by setting these to the minimum necessary thickness.
Further, since the fixed frame portion 10 is L-shaped and does not have a portion protruding to the wall member 5 side, after attaching the wall plate (wall member 5) to the base material 4, the wall plate is the same as in normal construction. The fixed frame portion 10 can be attached by providing an opening.
