JP 2003-120014 A

従来の壁面点検口の外枠では、ビスを打ち付けるだけであるため、製品原価が安価である利点がある反面、予め下地材の施工が必要であり、この下地材の施工には熟練技術を要する欠点がある。仮に、下地材の施工に不具合があると、外枠周壁部と下地材との対向間隔等に問題が生じ、結果的にビスの締付け加減が難しく、ビスを締めすぎると壁面（面材）と外枠との間の適正な隙間がなくなり、外枠が変形する不利がある。   The outer frame of the conventional wall inspection port only has to be screwed in, so there is an advantage that the product cost is low, but on the other hand, construction of the base material is necessary in advance, and the construction of this base material requires skill There are drawbacks. If there is a problem in the construction of the base material, there will be a problem in the facing distance between the outer frame peripheral wall and the base material. As a result, it is difficult to tighten and tighten the screws. There is a disadvantage that there is no proper gap between the outer frame and the outer frame is deformed.

一方、天井点検口の外枠には、ボルトを備えた「Ｌ字状」金具を外枠周壁部に取り付け、ボルトの先端と水平状縁部との間で面材を挟み付けるタイプ（図示せず）が知られている。このタイプでは、下地材の施工技術が不要な反面、外枠の仮止め後に固定金具の取り付け、更にボルトの締め付け等、取り付けに煩瑣な手順と手間がかかる不利がある。   On the other hand, on the outer frame of the ceiling inspection port, an “L-shaped” metal fitting provided with a bolt is attached to the peripheral wall of the outer frame, and a face material is sandwiched between the tip of the bolt and the horizontal edge (not shown) Is known). This type does not require a base material construction technique, but has the disadvantage that it requires troublesome procedures and labor, such as attaching a fixing metal fitting after the outer frame is temporarily fixed and further tightening a bolt.

この発明は、以上のような課題を解消させ、外枠の取り付けに下地材の施工が不要で、且つ熟練技術を必要としない許かりでなく、取り付け作業が簡単容易で、迅速強固に外枠を固定し得る点検口の外枠固定装置を提供することを目的とする。   The present invention eliminates the above-described problems, does not require the base material to be installed in the outer frame, and does not require skill, and the mounting operation is simple, easy, and fast and strong. An object of the present invention is to provide an outer frame fixing device for an inspection port that can fix a frame.

この目的を達成させるために、この発明の点検口の外枠固定装置では、次のような構成としている。
点検口の外枠固定装置は、外枠と、外枠の内枠支承部の裏面に配備される軸受けと、この軸受けに対向状に配備される内向き湾曲板と、基端に軸受けに軸承される回動軸部を備え、面内に内向き湾曲板が嵌挿する窓孔を設けると共に、外方向への回動で先端部が壁面の面材に衝き当たる回動板と、内向き湾曲板の湾曲面と回動板の窓孔との嵌挿間に配備され回動板の内向き回動を阻止するロック手段とから成ることを特徴としている。 In order to achieve this object, the inspection frame outer frame fixing device of the present invention has the following configuration.
The outer frame fixing device of the inspection port includes an outer frame, a bearing provided on the back surface of the inner frame support portion of the outer frame, an inwardly curved plate provided opposite to the bearing, and a bearing on the bearing at the base end. Provided with a rotating shaft portion, provided with a window hole into which the inwardly curved plate is fitted and inserted in the surface, and a rotating plate in which the tip portion hits the face material of the wall surface by turning outward, and inward It is characterized by comprising locking means that is arranged between the curved surface of the curved plate and the window hole of the rotating plate and prevents the rotating plate from turning inward.

このような構成を有する点検口の外枠固定装置では、回動板を外向き回動させることで、内向き湾曲板が回動板の窓孔を貫通し、窓孔と内向き湾曲板との嵌挿間に配備するロック手段で回動板の内向き回動を阻止させることとしたから、単に回動板を回動させるだけで、回動板の先端部が壁面の面材に衝き当たる状態が保持され、緩みなく強固に外枠を固定し得る。   In the outer frame fixing device of the inspection port having such a configuration, the inwardly curved plate passes through the window hole of the rotating plate by rotating the rotating plate outward, and the window hole and the inwardly curved plate Since the inward rotation of the rotating plate is prevented by the locking means provided between the insertion of the rotating plate, the tip of the rotating plate hits the wall material simply by rotating the rotating plate. The contact state is maintained, and the outer frame can be firmly fixed without loosening.

外枠の固定に際しては、単に回動板を外向きに回動させるだけであるから、下地材の施工及び熟練技術が不要であり、正確且つ迅速で強固な外枠の取り付けが実現し得る。   When the outer frame is fixed, the rotating plate is simply rotated outward, so that construction of the base material and skill are not required, and accurate, quick and strong outer frame attachment can be realized.

更に、この外枠に対し回動する回動板、内向き湾曲板及びロック手段を一体に配備する構造であるから、単に回動板の回動操作のみで取り付け作業が簡易迅速に実行し得、煩瑣な取り付け手順や手間を解消し得る等、発明目的を達成した優れた効果を有する。   Further, since the rotating plate, the inwardly curved plate, and the locking means that rotate with respect to the outer frame are integrally provided, the mounting operation can be performed simply and quickly by simply rotating the rotating plate. It has excellent effects of achieving the object of the invention, such as eliminating troublesome attachment procedures and labor.

外枠４は、方形の枠体で、周壁部４１と、周壁部４１の上部に設けられる水平状縁部４２と、下部に設けられる内枠支承部４３とからなる。
一方、内枠６１は周壁部６２の適所に外方へ張り出す嵌合溝部６３と、枠状の押え部６４を突出する嵌合板６５とを備える。嵌合板６５を嵌合溝部６３に嵌合することで、押え部６４が蓋材（面材７２と同一の化粧仕上げ材）６６を押さえ固定する。このとき、嵌合板６５面内にスリットを介して設けた係止爪６７が嵌合溝部６３（張り出し壁内面）の爪受け部６８に嵌着して固定される。 The outer frame 4 is a rectangular frame, and includes a peripheral wall portion 41, a horizontal edge portion 42 provided on the upper portion of the peripheral wall portion 41, and an inner frame support portion 43 provided on the lower portion.
On the other hand, the inner frame 61 includes a fitting groove portion 63 that protrudes outward at a proper position of the peripheral wall portion 62, and a fitting plate 65 that projects a frame-shaped presser portion 64. By fitting the fitting plate 65 into the fitting groove portion 63, the holding portion 64 presses and fixes the lid material (the same decorative finish material as the face material 72) 66. At this time, the locking claw 67 provided in the surface of the fitting plate 65 via the slit is fitted and fixed to the claw receiving portion 68 of the fitting groove 63 (inner surface of the overhanging wall).

図２で示すように、上記外枠４の内枠支承部４３の裏面４４適所には、嵌め入れ溝部４７が設けられ、この嵌め入れ溝部４７に平板状基板４８の両端部４８ａがスライド嵌着する。嵌め入れ溝部４７の先端側には後述する軸受け３を構成する半体部３ａが設けてある。   As shown in FIG. 2, a fitting groove 47 is provided at an appropriate position on the back surface 44 of the inner frame support 43 of the outer frame 4, and both end portions 48 a of the flat substrate 48 are slidably fitted into the fitting groove 47.

Further, an inwardly curved plate 2 that rises upward is erected in a position facing the half portion 3 b in the plane of the flat substrate 48. On the upper part of the half-body part 3b, an upright folding prevention part 31 is provided, which is intended to support inward tilting of the inwardly curved plate 2.

図３で示すように、前記回動板１は矩形平板を長さ中央で曲げ、先端側を上方へ湾曲する湾曲部１４と平板部１３とから成る。平板部１３の基端部には回動軸１１を設ける共に、平板部１３面内には上記内向き湾曲板２に対応し、内向き湾曲板２が挿し通る窓孔１２を開設している。この回動軸１１は、軸受け３の半体部３ａと半体部３ｂで回動可能に軸支される。   As shown in FIG. 3, the rotating plate 1 is composed of a curved portion 14 and a flat plate portion 13 that bend a rectangular flat plate at the center of the length and bend the tip side upward. A rotation shaft 11 is provided at the base end portion of the flat plate portion 13, and a window hole 12 corresponding to the inward curved plate 2 is formed in the surface of the flat plate portion 13 and the inward curved plate 2 is inserted. . The pivot shaft 11 is pivotally supported by the half body 3a and the half body 3b of the bearing 3 so as to be pivotable.

上記ロック手段５は、回動板１の窓孔１２と、内向き湾曲板２との嵌挿間に配備される。ロック手段５は、内向き湾曲部１４の湾曲外面に設けられた鋸歯状係止部５１と、窓孔１２の先端（回動軸１１と対向する）窓縁に設けられた爪５２とから成る。   The locking means 5 is arranged between the insertion of the window hole 12 of the rotating plate 1 and the inwardly curved plate 2. The locking means 5 includes a serrated locking portion 51 provided on the curved outer surface of the inwardly curved portion 14 and a claw 52 provided at the window edge of the tip of the window hole 12 (opposite the rotating shaft 11). .

図４で示すように、鋸歯状係止部５１の鋸歯は複数設けられ、外向きに上昇傾斜する傾斜面５１ａと、傾斜面に続く垂直面５１ｂとで構成され、爪５２は傾斜面５１ａに対応する傾斜状爪に設定してある。   As shown in FIG. 4, a plurality of serrations of the serrated locking portion 51 are provided, and are composed of an inclined surface 51a that rises and inclines outward, and a vertical surface 51b that follows the inclined surface, and the claw 52 is formed on the inclined surface 51a. The corresponding inclined nail is set.

実施の形態では、外枠４に嵌め入れ溝部４７を設け、平板状基板（半体部３ｂ・内向き湾曲板２を備えた）４８をスライド嵌脱可能に嵌着する例を示したが、これに限らず嵌め入れ溝部（半体部３ａを含む）４７を省略し、平板状基板４８を外枠４の内枠支承部４３に一体形成しても良い。この場合、軸受けの半体部３ｂは回動軸１１の全周面を囲む筒状で、且つ開口面の比較的大きい軸嵌め入れ用スリットを開設した略「Ｃ形」状の軸受け３に設定する（図示せず）。   In the embodiment, the fitting groove portion 47 is provided in the outer frame 4, and the flat board (having the half body portion 3 b and the inwardly curved plate 2) 48 is slidably fitted so as to be detachable. However, the present invention is not limited to this, and the fitting groove portion (including the half portion 3 a) 47 may be omitted, and the flat substrate 48 may be integrally formed with the inner frame support portion 43 of the outer frame 4. In this case, the half part 3b of the bearing is a cylindrical shape surrounding the entire circumferential surface of the rotating shaft 11, and is set to a substantially “C-shaped” bearing 3 having a relatively large opening for fitting the shaft. (Not shown).

このような構成を有する点検口の外枠固定装置では、外枠４を固定する場合は、図４に示す状態から回動板１を外方向へ回動させる。図５で示すように、この矢印方向への回動により内向き湾曲板２が窓孔１２を挿し通ることで、回動板１の外向きの回動が許容され、回動板１の先端部１５が面材７２に衝き当たる。   In the outer frame fixing device for an inspection port having such a configuration, when the outer frame 4 is fixed, the rotating plate 1 is rotated outward from the state shown in FIG. As shown in FIG. 5, when the inwardly curved plate 2 is inserted through the window hole 12 by the rotation in the direction of the arrow, the rotation of the rotation plate 1 is permitted and the tip of the rotation plate 1 is allowed to move. The part 15 hits the face material 72.

このとき、爪５２が鋸歯の傾斜面５１ａを押さえつけ状に乗り越え、且つ垂直面５１ｂに降下嵌着しかみ合う。これにより、面材７２に対し、先端部１５の衝き当たり状態が保持され、ロック手段５により回動板１の内方向への回動が阻止される。   At this time, the claw 52 climbs over the inclined surface 51a of the sawtooth so as to press down and engages with the vertical surface 51b only by being lowered. As a result, the contact state of the tip portion 15 with respect to the face member 72 is maintained, and the rotation of the rotating plate 1 in the inward direction is prevented by the lock means 5.

また、鋸歯（５１ａ、５１ｂ）は複数設けられているため、回動板１は先端部１５が面材７２に衝き当たるまで回動が許容される。したがって、多種類の面材７２厚みに対応でき、正確に緩みなく強固に外枠４の固定を実行し得る。   Further, since a plurality of saw teeth (51a, 51b) are provided, the rotating plate 1 is allowed to rotate until the distal end portion 15 hits the face material 72. Therefore, it is possible to deal with various types of face material 72 thickness, and the outer frame 4 can be fixed firmly and firmly without loosening.
