上記のような可動ルーバー面格子では、各ルーバーの端部に取り付けた合成樹脂製ブラケットの支軸部を金属製面格子周枠の内周側部材の軸孔に軸支していることから、泥棒が室内に侵入するためにバールなどの工具を使ってルーバーを破壊しようとした場合には、合成樹脂製の支軸部が極めて短時間で簡単に折れて、泥棒の室内侵入を容易にするという危険性があった。   In the movable louver surface lattice as described above, since the support shaft portion of the synthetic resin bracket attached to the end portion of each louver is supported by the shaft hole of the inner peripheral side member of the metal surface lattice peripheral frame, If a thief tries to break the louver using a tool such as a bar to allow the thief to enter the room, the support shaft made of synthetic resin can be easily folded in a very short time, making it easier for the thief to enter the room. There was a danger.

本発明は、上記のような課題に鑑み、泥棒が室内に侵入するためにバールなどの工具を使ってルーバーを破壊しようとする時、そのルーバーが簡単容易に破壊することがなく、防犯性能を高めることができる可動ルーバー面格子を提供することを目的とする。   In view of the above-described problems, the present invention provides a crime prevention performance when a burglar tries to break a louver using a tool such as a bar to penetrate the room, and the louver is not easily broken. It is an object of the present invention to provide a movable louvered face grid that can be enhanced.

上記課題を解決するための手段を、後述する実施形態の参照符号を付して説明すると、請求項１に係る発明は、面格子周枠４内に夫々中空状の横長又は縦長の多数のルーバー５を連動開閉可能に配設してなる可動ルーバー面格子において、
各ルーバー５にルーバー５よりも長さの長い金属製補強軸体９をルーバー５の回転軸線Ｇに沿って一体回転可能に貫通させ、この補強軸体９の両端部９ａ，９ａを、面格子周枠４の内周側部材１ｂ，１ｂに設けた軸孔１０，１０から夫々突出させると共に、軸受部材１１，１１を介して軸孔１０，１０に回転可能に軸支し、その軸孔１０，１０から突出した補強軸体９の突出端部９ａ，９ａにクランクアーム１２，１２を取り付け、各クランクアーム１２を連杆１４によって枢支連結してなることを特徴とする。 Means for solving the above-described problems will be described with reference numerals in the embodiments described later. The invention according to claim 1 relates to a large number of horizontally long or vertically long louvers in the plane lattice peripheral frame 4. In the movable louvered surface lattice that is arranged so that 5 can be opened and closed in conjunction with each other,
A metal reinforcing shaft 9 having a length longer than that of the louver 5 is passed through each louver 5 so as to be integrally rotatable along the rotation axis G of the louver 5, and both ends 9a, 9a of the reinforcing shaft 9 are connected to a plane lattice. Projecting from shaft holes 10 and 10 provided in the inner peripheral side members 1b and 1b of the peripheral frame 4, and rotatably supporting the shaft holes 10 and 10 via bearing members 11 and 11, respectively. , 10 are attached to the projecting ends 9a, 9a of the reinforcing shaft body 9 and the crank arms 12, 12 are pivotally connected by linkages 14.

請求項２は、請求項１に記載の可動ルーバー面格子において、補強軸体９は中空状体又は中実状体からなることを特徴とする。   According to a second aspect of the present invention, in the movable louvered surface grid according to the first aspect, the reinforcing shaft body 9 is formed of a hollow body or a solid body.

請求項３は、請求項１又は２に記載の可動ルーバー面格子において、補強軸体９は横断面が角形状又は円形状を成していることを特徴とする。   According to a third aspect of the present invention, in the movable louvered surface grid according to the first or second aspect, the reinforcing shaft body 9 has a square or circular cross section.

上記解決手段による発明の効果を、後述する実施形態の参照符号を付して説明すると、請求項１に係る発明の可動ルーバー面格子は、ルーバー５を貫通する金属製補強軸体９の両端部９ａ，９ａが軸受部材１１，１１を介して面格子周枠４の内周側部材１ｂ，１ｂに軸支されているから、泥棒が面格子から室内に侵入するためにバールなどの工具を使ってルーバー５を破壊しようとする時に、そのルーバー５の支軸部を例えば３〜５分の短時間で簡単容易に破壊することができず、そうこうしている間に泥棒はあきらめて逃げて行くか、そのうちに警報などによって駆けつけた警察官に捕まえられる、ということになり、従って可動ルーバー面格子の防犯性能を高めることができる。   The effect of the invention by the above solution will be described with reference numerals of the embodiments to be described later. The movable louvered surface lattice of the invention according to claim 1 is the both ends of the metal reinforcing shaft body 9 penetrating the louver 5. Since 9a and 9a are pivotally supported by the inner peripheral side members 1b and 1b of the surface lattice peripheral frame 4 via the bearing members 11 and 11, a thief uses a tool such as a bar to enter the room from the surface lattice. When trying to destroy the louver 5, the support shaft portion of the louver 5 cannot be easily broken in a short time, for example, 3 to 5 minutes, and does the thief give up and escape while doing so? In the meantime, it will be caught by police officers who rushed by alarms, etc., and therefore the crime prevention performance of the movable louvered surface lattice can be improved.

請求項２に係る発明の可動ルーバー面格子のように、補強軸体９は、中空状体からなるものでもよいし中実状体からなるものでもよい。   As in the movable louvered surface grid according to the second aspect of the present invention, the reinforcing shaft body 9 may be formed of a hollow body or a solid body.

請求項３に係る発明の可動ルーバー面格子のように、補強軸体９は、横断面形状が角形状でもよいし円形状でもよい。   As in the movable louvered surface grid according to the third aspect of the present invention, the reinforcing shaft body 9 may have a square or circular cross-sectional shape.

各ルーバー５には、図４に示すように、ルーバー５よりも長い金属製の補強軸体９が、ルーバー５の回転軸線Ｇに沿って一体回転可能に貫通され、この補強軸体９の両端部９ａ，９ａは、面格子周枠４を構成する縦枠１，１の内周側部材１ｂ，１ｂに設けてある軸孔１０，１０から夫々突出していると共に、軸受部材１１，１１を介して軸孔１０，１０に夫々回転可能に軸支され、その軸孔１０，１０から突出した補強軸体９の突出端部９ａ，９ａには、クランクアーム１２，１２が夫々取付部材１３，１３を介して取り付けられ、各クランクアーム１２は連杆１４によって枢支連結されている。   As shown in FIG. 4, a metal reinforcing shaft body 9 longer than the louver 5 is penetrated through each louver 5 so as to be integrally rotatable along the rotation axis G of the louver 5. The portions 9 a and 9 a protrude from shaft holes 10 and 10 provided in the inner peripheral side members 1 b and 1 b of the vertical frames 1 and 1 constituting the surface lattice peripheral frame 4, respectively, and via the bearing members 11 and 11. Crank arms 12 and 12 are respectively attached to the projecting end portions 9a and 9a of the reinforcing shaft body 9 that are rotatably supported by the shaft holes 10 and 10 and project from the shaft holes 10 and 10, respectively. The crank arms 12 are pivotally connected by linkages 14.

補強軸体９は、鋼製又はステンレス製で横断面が正方形の角形管からなるもので、図４に示すように、ルーバー５の長さＬ05よりも長い長さＬ09を有する。各軸受部材１１は、耐摩耗性及び摺動性に優れた合成樹脂によって形成されている。クランクアーム１２及び取付部材１３は、前記軸受部材１１と同じような合成樹脂によって形成され、連杆１４は鋼板又はステンレス板によって形成される。 The reinforcing shaft body 9 is made of a square tube having a square cross section made of steel or stainless steel, and has a length L 09 longer than the length L 05 of the louver 5 as shown in FIG. Each bearing member 11 is made of a synthetic resin excellent in wear resistance and sliding property. The crank arm 12 and the mounting member 13 are formed of a synthetic resin similar to the bearing member 11, and the linkage 14 is formed of a steel plate or a stainless steel plate.

前記取付部材１３は、図５の(a) 及び(c) に示すように、その一端面側に、補強軸体９の端部内に嵌合する嵌合突起部１３ａと補強軸体９の端部９ａを受け入れる環状の受入溝部１３ｂとを有し、他端面側に短四角柱状の嵌合凸部１３ｃを有し、そして中心軸線に沿って両端面を貫くネジ孔１３ｄを有する。   As shown in FIGS. 5 (a) and 5 (c), the mounting member 13 has a fitting projection 13a fitted into the end of the reinforcing shaft 9 and the end of the reinforcing shaft 9 on one end face side. An annular receiving groove portion 13b for receiving the portion 9a, a short quadratic columnar fitting convex portion 13c on the other end surface side, and a screw hole 13d penetrating both end surfaces along the central axis.

前記クランクアーム１２も、図５の(a) 及び(c) に示すように、一端面側には、取付部材１３の短四角柱状の嵌合凸部１３ｃが嵌合する嵌合凹部１２ａを有し、他端面側には、ネジ具１６を挿入する挿通部１２ｂが嵌合凹部１２ａと同軸状に形成されると共に、ネジ具挿通部１２ｂの下方側に連杆取付用突起１５が突設され、この突起１５には係止ヘッド１５ａ及び割溝１５ｂが形成されている。   As shown in FIGS. 5 (a) and 5 (c), the crank arm 12 also has a fitting recess 12a on one end face side to which the short square column-like fitting projection 13c of the mounting member 13 is fitted. On the other end surface side, an insertion portion 12b for inserting the screw tool 16 is formed coaxially with the fitting recess 12a, and a continuous attachment projection 15 is provided below the screw tool insertion portion 12b. The projection 15 is formed with a locking head 15a and a split groove 15b.

面格子周枠４の縦枠１に対するルーバー５の取付け、このルーバー５を貫通する補強軸体９の取付け、及びこの補強軸体９に対するクランクアーム１２の取付けについて図５の(a) 〜(c) を参照して説明すると、先ず、左右各縦枠１の内周側部材１ｂに設けてある各軸孔１０に軸受部材１１を同図の(a) に示すように嵌合しておき、また各ルーバー５には補強軸体９を貫通させて、その両端部９ａ，９ａをルーバー５の両端から夫々突出させておく。   The attachment of the louver 5 to the vertical frame 1 of the surface lattice peripheral frame 4, the attachment of the reinforcing shaft 9 passing through the louver 5, and the attachment of the crank arm 12 to the reinforcing shaft 9 are shown in FIGS. ), The bearing member 11 is first fitted into each shaft hole 10 provided in the inner peripheral side member 1b of each of the left and right vertical frames 1 as shown in FIG. Further, the reinforcing shaft body 9 is passed through each louver 5, and both end portions 9 a, 9 a are projected from both ends of the louver 5.

ルーバー５の両端から夫々突出させた補強軸体９の端部９ａを、左右各縦枠１の内周側部材１ｂに取り付けた軸受部材１１に対しその内側から挿通させて外側へ突出させ、その突出端部９ａに取付部材１３を取り付ける。即ち、取付部材１３の嵌合凸部１３ｃを補強軸体９の端部９ａ内に嵌合させると共に、補強軸体９の端部９ａを取付部材１３の環状受入溝部１３ｂに強く押し込むことによって、取付部材１３を補強軸体９の端部９ａに夫々取り付ける。   The end portions 9a of the reinforcing shaft body 9 projecting from both ends of the louver 5 are inserted from the inside to the bearing member 11 attached to the inner peripheral side member 1b of each of the left and right vertical frames 1, and are projected outward. The attachment member 13 is attached to the protruding end portion 9a. That is, by fitting the fitting convex portion 13c of the mounting member 13 into the end portion 9a of the reinforcing shaft body 9, and strongly pushing the end portion 9a of the reinforcing shaft body 9 into the annular receiving groove portion 13b of the mounting member 13, The attachment members 13 are attached to the end portions 9a of the reinforcing shaft body 9, respectively.

その後、クランクアーム１２の嵌合凹部１２ａを取付部材１３の嵌合凸部１３ｃに対し嵌合し、ネジ具１６をクランクアーム１２のネジ具挿通部１２ｂから取付部材１３のネジ孔１３ｄにねじ込んで締め付けることによって、クランクアーム１２を取付部材１３に固定する。   Thereafter, the fitting recess 12a of the crank arm 12 is fitted into the fitting projection 13c of the mounting member 13, and the screw 16 is screwed into the screw hole 13d of the mounting member 13 from the screw insertion portion 12b of the crank arm 12. The crank arm 12 is fixed to the attachment member 13 by tightening.

上記のように左右各縦枠１の内周側部材１ｂに取り付けた軸受部材１１から突出させた補強軸体９の突出端部９ａに取付部材１３を介してクランクアーム１２を取り付けた後、連杆１４に長さ方向一定間隔おきに設けてある取付孔１４ａ（長孔）を各クランクアーム１２の連杆取付用突起１５に嵌め込む。この場合、突起１５には係止ヘッド１５ａに割溝１５ｂが形成してあるから、この割溝１５ｂを介して係止ヘッド１５ａを縮径した状態で取付孔１４ａを突起１５に嵌め込めばよい。   After attaching the crank arm 12 to the projecting end portion 9a of the reinforcing shaft body 9 projecting from the bearing member 11 attached to the inner peripheral side member 1b of each of the left and right vertical frames 1 as described above via the attachment member 13, Mounting holes 14a (long holes) provided in the flange 14 at regular intervals in the length direction are fitted into the continuous mounting protrusions 15 of the crank arms 12. In this case, since the projection 15 has a split groove 15b formed in the locking head 15a, the mounting hole 14a may be fitted into the projection 15 with the locking head 15a having a reduced diameter via the split groove 15b. .

上記のようにして面格子周枠４内に多段状に配設した多数のルーバー５を開閉操作するには、図示は省略するが、多数のルーバー５の何れか一つに取り付けてある開閉操作用のハンドルを操作することによって、全てのルーバー５を一斉に開閉させることができる。図２には全てのルーバー５が閉鎖した状態を実線で示し、開放した状態を仮想線で示す。閉鎖状態では、隣り合うルーバー５，５の対向する係嵌溝部８，８どうしが係嵌し合っている。   In order to open and close a large number of louvers 5 arranged in a multistage manner in the plane lattice peripheral frame 4 as described above, although not shown, the opening and closing operations attached to any one of the many louvers 5 By operating the handle, all louvers 5 can be opened and closed simultaneously. In FIG. 2, a state in which all the louvers 5 are closed is indicated by a solid line, and an open state is indicated by a virtual line. In the closed state, the engaging groove portions 8 and 8 facing each other of the adjacent louvers 5 and 5 are engaged with each other.

以上説明したように、この可動ルーバー面格子は、各ルーバー５に、ルーバー５よりも長い横断面正方形の角形管からなる金属製の補強軸体９をルーバー５の回転軸線Ｇに沿って一体回転可能に貫通させ、この補強軸体９の両端部９ａ，９ａを、面格子周枠４の内周側部材４ａに設けた軸孔１０から夫々突出させると共に、軸受部材１１を介して軸孔１０に回転可能に軸支し、その軸孔１０から突出した補強軸体９の突出端部９ａにクランクアーム１２を取り付け、各クランクアーム１２を連杆１４により枢支連結してなるもので、図４からも分かるように、ルーバー５を貫通する金属製補強軸体９の両端部９ａ，９ａが軸受部材１１，１１を介して面格子周枠４の内周側部材４ａに軸支されているから、泥棒が面格子から室内に侵入するためにバールなどの工具を使ってルーバー５を破壊しようとしても、そのルーバー５の支軸部を例えば３〜５分の短時間で簡単容易に破壊することができず、そうこうしている間に、泥棒は、あきらめて逃げて行くか、そのうち警報などによって駆けつけた警察官に捕まえられることになる。   As described above, in this movable louvered surface lattice, each louver 5 is integrally rotated along the rotation axis G of the louver 5 with a metal reinforcing shaft 9 made of a square tube having a square cross section longer than the louver 5. Both end portions 9a, 9a of the reinforcing shaft body 9 are allowed to pass through and protrude from the shaft holes 10 provided in the inner peripheral side member 4a of the surface lattice peripheral frame 4, and the shaft holes 10 are inserted through the bearing members 11. The crank arm 12 is attached to the projecting end 9a of the reinforcing shaft body 9 projecting from the shaft hole 10 so as to be rotatable, and each crank arm 12 is pivotally connected by a linkage 14. As can be seen from FIG. 4, both end portions 9 a, 9 a of the metal reinforcing shaft body 9 penetrating the louver 5 are pivotally supported by the inner peripheral side member 4 a of the plane lattice peripheral frame 4 via the bearing members 11, 11. From the thief to enter the room Even if it tries to destroy the louver 5 using a tool such as a bar, the supporting shaft portion of the louver 5 cannot be easily and easily broken in a short time, for example, 3 to 5 minutes. Will be given up and run away, or will be caught by police officers who rushed by warnings.

上記実施形態の説明では、補強軸体９として、図６の(a) に示すような鋼製又はステンレス製で横断面が正方形の角形管からなる補強軸体９ａを使用したが、本発明に係る補強軸体９としては、横断面が正方形の角形管以外に、図６の(b) に示すような横断面が正方形で中実状の補強軸体９ｂでもよいし、あるいは同図の(c) に示すような円管状の補強軸体９ｃでもよく、また同図の(d) に示すような横断面が円形で中実状の補強軸体９ｄでもよい。   In the description of the above embodiment, the reinforcing shaft body 9a made of a square tube having a square cross section made of steel or stainless steel as shown in FIG. 6 (a) is used as the reinforcing shaft body 9. The reinforcing shaft body 9 may be a solid reinforcing shaft body 9b having a square cross section as shown in FIG. 6B, in addition to a square tube having a square cross section, or (c) of FIG. ) Or a cylindrical reinforcing shaft 9d having a circular cross section and a solid shape as shown in FIG.

尚、図６の(a) 及び(b) に示す補強軸体９ａ，９ｂのように、補強軸体９の横断面が四角角形である場合は、ルーバー５の中空部内に設けた係合凹部７を角形補強軸体９の四隅の夫々外隅部に係合させて、ルーバー５内に補強軸体９を回転不能に保持することができるが、図６の(c) 及び(d) に示す補強軸体９ｃ，９ｄのように、補強軸体９の横断面が円形である場合は、そのままでは補強軸体９を回転不能に保持できないため、(c) 及び(d) に示すように、各補強軸体９ｃ，９ｄの外周面の夫々少なくとも２箇所に係合凹条部１７を設けると共に、この凹溝条１７に係合する係合凸条部１８をルーバー５の中空部内に設け、それによって補強軸体９ｃ，９ｄをルーバー５内に回転不能に保持するようにしている。   In addition, when the cross section of the reinforcing shaft body 9 is a square shape like the reinforcing shaft bodies 9a and 9b shown in FIGS. 6A and 6B, the engaging recess provided in the hollow portion of the louver 5 is used. 7 can be engaged with the outer corners of each of the four corners of the square reinforcing shaft body 9 to hold the reinforcing shaft body 9 in the louver 5 in a non-rotatable manner, as shown in FIGS. 6 (c) and 6 (d). When the reinforcing shaft body 9 has a circular cross section like the reinforcing shaft bodies 9c and 9d shown, the reinforcing shaft body 9 cannot be held unrotatably as it is, and as shown in (c) and (d) In addition, the engaging groove portions 17 are provided in at least two locations on the outer peripheral surfaces of the reinforcing shaft bodies 9c and 9d, and the engaging protrusion portions 18 that engage with the groove portions 17 are provided in the hollow portion of the louver 5. Thereby, the reinforcing shafts 9c and 9d are held in the louver 5 in a non-rotatable manner.

また、上記実施形態では、面格子周枠４内に夫々横長の多数のルーバー５を連動開閉可能に配設した可動ルーバー面格子について説明したが、本発明は、面格子周枠４内に夫々縦長の多数のルーバー５を連動開閉可能に配設した可動ルーバー面格子にも適用されるものである。   In the above-described embodiment, the movable louver surface lattice has been described in which a large number of horizontally long louvers 5 are disposed in the surface lattice peripheral frame 4 so as to be able to be interlockedly opened and closed.
