Description

この発明は、例えば床下或いは天井等の点検口の外枠装置に関する。   The present invention relates to an outer frame device for an inspection port such as a floor or a ceiling.

図６は、従来の床下点検口の外枠を施工した状態を示している。
この点検口の外枠７は、立上り壁７１と、立上り壁７１の上端を外向きに折り曲げた水平つば７２と、立上り壁７１の下端に連続し内向きに突出する箱状受け部７３とから成る。 FIG. 6 shows a state in which an outer frame of a conventional underfloor inspection port is constructed.
The outer frame 7 of the inspection port includes a rising wall 71, a horizontal collar 72 obtained by bending the upper end of the rising wall 71 outward, and a box-shaped receiving portion 73 that is continuous with the lower end of the rising wall 71 and protrudes inward. Become.

床下点検口の施工に際しては、根太８１と床補強材８２と床材８３とで構成される床面８の適所に、点検口用の開口８４が開設される。この開口端面（床面８端面）に上記立上り壁７１を対応させた状態で、水平つば７２を床面８に載せ置く。   When the underfloor inspection port is constructed, an opening 84 for the inspection port is opened at an appropriate position on the floor surface 8 composed of the joists 81, the floor reinforcing material 82, and the floor material 83. The horizontal collar 72 is placed on the floor surface 8 with the rising wall 71 corresponding to the opening end surface (end surface of the floor surface 8).

ここで、立上り壁７１面内のビス孔７１ａから床材８３に対し、ビス７１ｂを打ち込み、床面８に対し外枠７を額縁状に固定する。一方、床開口に際し切り出した床材を方形状の蓋板８５とし、この蓋板８５の外縁に略断面「コ」の字状の内枠８６を固着して、内枠８６の底面をハコ状受け部７３の上面で支承する。
特開２００３−１２００１４公報 Here, the screw 71b is driven into the floor material 83 from the screw hole 71a in the surface of the rising wall 71, and the outer frame 7 is fixed to the floor surface 8 in a frame shape. On the other hand, the floor material cut out when the floor is opened is used as a rectangular lid plate 85, and an inner frame 86 having a substantially cross-sectional “U” shape is fixed to the outer edge of the lid plate 85, so It is supported on the upper surface of the receiving portion 73.
JP 2003-120014 A

従来の床下点検口の外枠では、立上り壁から床端面に対しビス打ちして固定する。このため、このビスを締め付けすぎると、床端面と外枠との間の適正な隙間がなくなり外枠が変形する。   The outer frame of the conventional underfloor inspection port is fixed by screwing from the rising wall to the floor end surface. For this reason, if this screw is tightened too much, an appropriate gap between the floor end surface and the outer frame disappears and the outer frame is deformed.

他方、ビスの締め付け強度が十分でないと、ハコ状受け部の下方の支えがないことと相俟って、蓋板にかかる負荷は水平つばの設置面でのみ支承する結果となり、水平つばの設置面が支点となって、外枠は矢印Ｈ方向へ変形する。   On the other hand, if the tightening strength of the screw is not sufficient, the load on the cover plate is supported only on the installation surface of the horizontal collar, coupled with the lack of support below the box-shaped receiving part. The outer frame is deformed in the direction of arrow H with the surface as a fulcrum.

仮に、図６の仮想線で示すように、ハコ状受け部７３を支える受け桟８７を別途、根太８１に取付けた場合、外枠の上記変形は解消し得る。しかし、この施工には床面開口寸法の正確性、受け桟の上面高さの正確性が必要であり、作業が極めて煩瑣で、且つ熟練を要する等の不利があった。   If the receiving bar 87 that supports the box-shaped receiving part 73 is separately attached to the joist 81 as shown by the phantom line in FIG. 6, the above deformation of the outer frame can be eliminated. However, this construction requires the accuracy of the floor surface opening size and the accuracy of the height of the upper surface of the receiving bar, and is disadvantageous in that the work is extremely cumbersome and requires skill.

この発明は、以上のような課題を解消させ、シンプルな構成であって、簡単容
易且つ迅速な取付け施工が実現できる許かりでなく、外枠の変形も生じず適正強
固に取付け得る点検口の外枠装置を提供することを目的とする。 The present invention eliminates the above-mentioned problems and has a simple configuration, which is not allowed to achieve simple and quick installation work, and does not cause deformation of the outer frame. An object is to provide an outer frame device.

この目的を達成させるために、この発明の点検口の外枠装置では、次のような構成としている。
点検口の外枠装置は、外枠と、外枠の底部に設けた嵌合部と、この嵌合部に嵌脱可能に嵌着する頭部に垂下レールを備えた固定支柱と、一端部側の面内に垂下レール上を昇降し且つ係止可能な窓孔を備えると共に、他端部側に先端を床底面に突き当てる弓なり状の引っ掛けアームを備える弓形係止体とから成ることを特徴としている。 In order to achieve this object, the outer frame device for an inspection port according to the present invention has the following configuration.
The outer frame device of the inspection port includes an outer frame, a fitting portion provided at the bottom of the outer frame, a fixed column having a hanging rail on the head that is detachably fitted to the fitting portion, and one end portion And a bow-shaped latching body having a bow-like hook arm with a tip abutting against the floor at the other end side. It is a feature.

このような構成を有する点検口の外枠装置では、外枠に固定される固定支柱に対し弓形係止体を上昇させ、弓なり状引っ掛けアームの先端を床底面に突き当てた状態で、弓形係止体と固定支柱とを係止させることとしたから、単に固定支柱に対し弓形係止体を上昇させるだけの極めて簡単容易、且つ迅速な操作で、外枠を床面に取付けることができる。   In the outer frame device of the inspection port having such a configuration, the bow-shaped engagement body is raised with respect to the fixed support fixed to the outer frame, and the bow-shaped hook arm is abutted against the floor bottom surface, Since the stationary body and the fixed support are locked, the outer frame can be attached to the floor surface by an extremely simple, easy and quick operation of simply raising the arcuate locking body relative to the fixed support.

また、取付時、外枠に全く余分な外力が作用しないため、外枠が変形するなどの不利がない許かでなく、適正強固に取付けし得る。更に、弓形係止体の引き上げ（押し上げ）は、床面の厚みに応じて行い得るから、床材厚みにかかわらず施工し得る。   In addition, since no extra external force acts on the outer frame at the time of mounting, the outer frame can be mounted firmly and properly without any disadvantages such as deformation. Further, the lifting (pushing up) of the arcuate locking body can be performed according to the thickness of the floor surface, and therefore can be performed regardless of the thickness of the floor material.

更に、弓形係止体は、弓なりに反っているため、それ自体、弾力性、弾発性を備えている。従って、床材に対する係止力は勿論、固定支柱に対する係止力も強靭で、安全且つ適正に取付けし得る等、発明目的を達成した優れた効果を有する。   Furthermore, since the bow-shaped locking body is warped like a bow, it itself has elasticity and elasticity. Therefore, not only the locking force to the flooring but also the locking force to the fixed support column is strong, and it has an excellent effect of achieving the invention object, such as being able to attach safely and appropriately.

以下、図面に基づき本発明に係る点検口の外枠装置の具体的な実施の形態を説明する。
図１は、床下点検口の外枠装置を示す斜視図である。
床下点検口の外枠装置は、外枠３と、外枠３の下部に設ける嵌合部４と、この嵌合部４に嵌脱可能に嵌着固定される固定支柱２と、この固定支柱２に対し昇降し、先端が床材８底面に突き当るとき、固定支柱２に固定される弓形係止体１とから構成される。 Hereinafter, specific embodiments of an outer frame device for an inspection port according to the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an outer frame device of an underfloor inspection port.
The outer frame device of the underfloor inspection port includes an outer frame 3, a fitting portion 4 provided at a lower portion of the outer frame 3, a fixed column 2 that is detachably fitted to the fitting unit 4, and the fixed column. And an arcuate locking body 1 that is fixed to the fixed support 2 when the front end abuts against the bottom surface of the flooring 8.

外枠３は、例えばアルミ材、ステンレス材等の金属製板体で、床面８に接面上に載置する矩形状の床面載置部３２と、この床面載置部３２の一側片に直角状に連続する垂直部３１と、垂直部３１の下辺に直角状に連続する内枠支承面３３とから成る。   The outer frame 3 is, for example, a metal plate such as an aluminum material or a stainless material, and has a rectangular floor surface mounting portion 32 that is mounted on a contact surface on the floor surface 8 and one of the floor surface mounting portions 32. It consists of a vertical part 31 that is perpendicular to the side piece and an inner frame support surface 33 that is perpendicular to the lower side of the vertical part 31.

床面載置部３２の内面には、垂直部３１と平行する上側突き当て部３２ａを備えている。また、外枠３の下部すなわち内枠支承面３３の下部には、後述する固定支柱２の頭部が嵌着する嵌合部４が配備してある。   On the inner surface of the floor mounting part 32, an upper abutting part 32a parallel to the vertical part 31 is provided. In addition, a fitting portion 4 to which a head of a fixed column 2 to be described later is fitted is disposed below the outer frame 3, that is, below the inner frame support surface 33.

前記嵌合部４は、内枠支承面３３の一側片に直角状に連続する垂直面４３と、内枠支承面３３の他側片、つまり垂直部３１との交点部を外方向へ延長した延長部４１と、延長部４１の先端に直角状に連続する下側突き当て部４２と、突き当て部４２の下端に直交状に連続する受け底面４４とから成る。   The fitting portion 4 extends outward at the intersection of the vertical surface 43 that is perpendicular to one side piece of the inner frame support surface 33 and the other side piece of the inner frame support surface 33, that is, the vertical portion 31. The extended portion 41, a lower abutting portion 42 that is perpendicular to the tip of the extended portion 41, and a receiving bottom surface 44 that is orthogonal to the lower end of the abutting portion 42.

上記垂直面４３と受け底面４４との間には、開口面４５が開口してある。また、受け底面４４の先端には上方向（内枠支承面３３方向）へ立ち上がる突条４４ａを設けると共に、垂直面４３の下辺内側に爪４３ａが設けてある。   An opening surface 45 is opened between the vertical surface 43 and the receiving bottom surface 44. In addition, a protrusion 44 a that rises upward (in the direction of the inner frame support surface 33) is provided at the tip of the receiving bottom surface 44, and a claw 43 a is provided inside the lower side of the vertical surface 43.

図２は、固定支柱２と弓形係止体１とを分離した分解斜視図を示す。
固定支柱２は、矩形平板状の頭部２１と、この頭部２１の裏面に突出され、前記開口面４５から下方へ臨出する円板状の回動用臨出部２２と、回動用臨出部２２

ック部２４とから成る。 FIG. 2 shows an exploded perspective view in which the fixed support 2 and the arcuate locking body 1 are separated.
The fixed support 2 has a rectangular flat plate-shaped head portion 21, a disk-shaped rotation projecting portion 22 that protrudes downward from the opening surface 45 and protrudes downward from the opening surface 45. Part 22
Are formed of a thin plate-like hanging rail 23 that is continuous with the bottom surface of the board and a hook portion 24 provided at the lower portion of the hanging rail 23.

上記垂下レール２３は、頭部２１側が幅広２３ａで、フック部２４側へかけて順次幅狭２３ｂとなるテーパー状（或いは勾配状）に設定してある。上部の幅広部分の幅は、後述する弓形係止体１の長方形状の窓孔１３の長さより僅かに小径に設定してある。   The hanging rail 23 is set in a tapered shape (or a gradient shape) having a wide 23a on the head 21 side and a narrow width 23b sequentially toward the hook portion 24 side. The width of the upper wide portion is set slightly smaller than the length of the rectangular window hole 13 of the arcuate locking body 1 described later.

実施の形態では、上記頭部２１は垂下レール２３に対し僅かに時計回り方向へ軸変位させて固定してある。この角度変位により、施工をし直す際など、僅かな反時計回りへの回動で、頭部２１が開口面４３から脱するように設定してある。   In the embodiment, the head 21 is fixed by being axially displaced in the clockwise direction with respect to the hanging rail 23. Due to this angular displacement, the head 21 is set so as to be detached from the opening surface 43 by a slight counterclockwise rotation, for example, when construction is performed again.

上記弓形係止体１は、平板状の金属板で、水平状の翼部１１と弓なりに反った引っ掛けアーム１２とから成る略「Ｔ」字状のバネ板である。略小判形をした翼部１１の面内中央には、矩形の窓孔１３が開口してある。また、引っ掛けアーム１２は翼部１１の下辺中央に連続し、先端１２ａが最上位のポジションを保持する弓なりに反っている。   The arcuate locking body 1 is a flat metal plate, and is a substantially “T” -shaped spring plate comprising a horizontal wing portion 11 and a hook arm 12 that warps in a bow shape. A rectangular window hole 13 is opened at the center in the surface of the substantially oblong wing part 11. Further, the hook arm 12 continues to the center of the lower side of the wing part 11, and the tip 12a warps in a bow shape that holds the uppermost position.

上記窓孔１３は、細い長方形状の貫通孔で、短辺１３ａが垂下レール２３の厚みより大きく、長辺１３ｂが垂下レール２３の上部幅より、僅かに大に設定してある。従って、フック部２３に窓孔１３を嵌めいれるとき、窓孔１３は垂下レール２３上を昇降する。   The window hole 13 is a thin rectangular through-hole, the short side 13 a is set larger than the thickness of the hanging rail 23, and the long side 13 b is set slightly larger than the upper width of the hanging rail 23. Therefore, when the window hole 13 is fitted in the hook portion 23, the window hole 13 moves up and down on the hanging rail 23.

更に、引っ掛けアーム１２は、外方向（床面８の裏面方向）へ弓なりに反るように湾曲させてある。また、上記窓孔１３の両側にはガイド突子１４設け、貫通する垂下レール２３の両側面に対応し、引っ掛けアーム１２の昇動動作を円滑にする。   Further, the hook arm 12 is curved so as to bow outwardly (toward the back surface of the floor surface 8). In addition, guide protrusions 14 are provided on both sides of the window hole 13 so as to correspond to both side surfaces of the penetrating rail 23, and the raising operation of the hook arm 12 is made smooth.

このような構成を有する点検口の外枠装置では、図１で示すように、外枠３の嵌合部４に対し、固定支柱２を取付ける。つまり、頭部２１を、長辺２１ａが受け底面４４の先端（突条４４ａ）に対応する状態で開口面４５に挿入する。   In the outer frame device of the inspection port having such a configuration, the fixed support 2 is attached to the fitting portion 4 of the outer frame 3 as shown in FIG. That is, the head 21 is inserted into the opening surface 45 with the long side 21 a corresponding to the tip of the receiving bottom surface 44 (the protrusion 44 a).

図３で示すように、固定支柱（頭部２１）２を時計回り方向へ回動させると、頭部２１の一方の短辺２１ｄが垂直面４３に接面すると共に、他方の短辺２１ｃが下側突き当て面４２の内面に接面して固定される。つまり、頭部２１が嵌合部４（の溝）に嵌着する。   As shown in FIG. 3, when the fixed column (head 21) 2 is rotated clockwise, one short side 21d of the head 21 comes into contact with the vertical surface 43 and the other short side 21c is The lower abutting surface 42 is fixed in contact with the inner surface. That is, the head 21 is fitted into the fitting part 4 (groove).

この状態において、図３で示すように、回動用臨出部２２が開口面４５から下方へ臨出し、且つ垂下レール２３の切り欠き上面２３ｃが受け底面４４の外面に接面している。ここで、弓形係止体１を垂下レール２３に嵌合する。つまり、窓孔１３にフック部２４を通す。これにより、弓形係止体１が固定支柱２に吊下される。   In this state, as shown in FIG. 3, the rotation projecting portion 22 projects downward from the opening surface 45, and the cut-out upper surface 23 c of the hanging rail 23 is in contact with the outer surface of the receiving bottom surface 44. Here, the arcuate locking body 1 is fitted to the hanging rail 23. That is, the hook portion 24 is passed through the window hole 13. As a result, the arcuate locking body 1 is suspended from the fixed support 2.

ここにおいて、図４で示すように、外枠３の床面載置部３２を床面８に接面させる。そして、弓形係止体１を上方へ押し上げ、垂下レール２３上を上昇させる。この状態で、引っ掛けアームの先端１２ａが床材８底面に対向している。   Here, as shown in FIG. 4, the floor surface mounting portion 32 of the outer frame 3 is brought into contact with the floor surface 8. Then, the arcuate locking body 1 is pushed upward to raise the hanging rail 23. In this state, the tip 12a of the hook arm faces the bottom surface of the flooring 8.

図５は、外枠３が床材８に固定される原理説明図である。
引っ掛けアーム１２の長さ中央部を力Ｆで押し上げ、垂下レール２３上を上昇させると、引っ掛けアーム１２の先端１２ａが床材８の底面に突き当る。この状態で、さらに引っ掛けアーム２を押し上げると、弓形係止体１が固定支柱２に固定される。 FIG. 5 is an explanatory diagram of the principle in which the outer frame 3 is fixed to the flooring 8.
When the central portion of the length of the hook arm 12 is pushed up with a force F and raised on the hanging rail 23, the tip 12 a of the hook arm 12 hits the bottom surface of the flooring 8. When the hook arm 2 is further pushed up in this state, the arcuate locking body 1 is fixed to the fixed support 2.

すなわち、図５で示すように、力Ｆによって、引き上げられた引っ掛けアーム先端１２ａが床材８底面に当たると、この突き当て点Ｃが支点となる。
この状態から更に、引っ掛けアーム１２を引き上げると、引っ掛けアーム１２の窓孔１３の点ａ及び点ｂが垂下レール２３に当たる。ここにおいて、窓孔１３の開口寸法より垂下レ−ル２３の方が大きいため、点ａに内向きの力ｆ１及び点ｂに外向きの力ｆ２が発生する。 That is, as shown in FIG. 5, when the hook arm tip 12 a pulled up by the force F hits the bottom surface of the flooring 8, this abutting point C becomes a fulcrum.
When the hook arm 12 is further pulled up from this state, the points a and b of the window hole 13 of the hook arm 12 hit the hanging rail 23. Here, since the hanging rail 23 is larger than the opening size of the window hole 13, an inward force f1 is generated at the point a and an outward force f2 is generated at the point b.

そして、引っ掛けアーム１２の引き上げ力をなくすと、引っ掛けアーム１２の反発力によって、点ｃに下方向の力ｆ３、点ｂに内向き下方向の力ｆ４、更に点ａに上向き外方向の力ｆ５へと変化し、点ｃが力点、点ａが支点、そして点ｂが作用点となる。   When the lifting force of the hook arm 12 is eliminated, the repulsive force of the hook arm 12 causes a downward force f3 at the point c, an inward and downward force f4 at the point b, and an upward and outward force f5 at the point a. The point c becomes a power point, the point a becomes a fulcrum, and the point b becomes an action point.

これにより、引っ掛けアーム１２の点ｂの力ｆ４が、垂下レール３に作用し続ける結果、引っ掛けアーム１２が強固に係止する。
仮に、外枠を持ち上げようとすると、点ｃにｆ３の力が増大し、且つ点ｂのｆ４の力も増大するため、一層保持力が発生し強固に止着される。 As a result, the force f4 at the point b of the hook arm 12 continues to act on the hanging rail 3, so that the hook arm 12 is firmly locked.
If the outer frame is lifted, the force at f3 increases at the point c and the force at f4 at the point b also increases, so that a further holding force is generated and firmly fixed.
