図面は、本発明に係る建物開口部用面格子装置の実施例を示すものである。この面格子装置１は、図１に示すように、建物開口部２に取り付けられた引き違い式の戸障子３の室内側に面格子４を装着することにより構成されるもので、該面格子４は、図１〜図５から分かるように、互いに平行を成す第１及び第２縦枠材１１，１２と、互いに平行を成してこれら縦枠材同士を相互に連結する複数の横桟材１３とから成る第１格子体１０、並びに、互いに平行を成す第１及び第２縦枠材２１，２２と、互いに平行を成してこれら縦枠材同士を相互に連結する複数の横桟材２３とから成る第２格子体２０を備え、第１及び第２格子体１０，２０における上記横桟材１３，２３が互いに異なる高さに設けられて、以下に述べるような態様で第１及び第２格子体１０，２０を相互に連結することにより面格子４を構成している。   The drawings show an embodiment of a surface grating device for a building opening according to the present invention. As shown in FIG. 1, the surface lattice device 1 is configured by mounting a surface lattice 4 on the indoor side of a sliding type sliding door 3 attached to a building opening 2. As can be seen from FIG. 1 to FIG. 5, the first and second vertical frame members 11 and 12 that are parallel to each other and a plurality of horizontal rails that are parallel to each other and connect these vertical frame members to each other. A first grid 10 made of a material 13, and first and second vertical frame members 21 and 22 that are parallel to each other, and a plurality of horizontal rails that are parallel to each other and connect these vertical frame members to each other. The crosspieces 13 and 23 in the first and second grids 10 and 20 are provided at different heights from each other, and the first and second crossbars 13 and 23 are formed in the manner described below. And the surface grating | lattice 4 is comprised by connecting the 2nd grating | lattice bodies 10 and 20 mutually.

即ち、上記第１及び第２格子体１０，２０における建物開口部２の中央部側に位置する各第２縦枠材１２，２２は、それぞれ他方の格子体２０，１０における第１縦枠材２１と第２縦枠材２２との間、及び第１縦枠材１１と第２縦枠材１２との間に位置して、両格子体１０，２０における各横桟材１３，２３が他方の格子体２０，１０における第２縦枠材２２，１２に設けられた貫通穴２４，１４にそれぞれ挿通され、両第２縦枠材１２，２２は、両格子体１０，２０を最も拡張させた状態（図１、図２及び図４参照）で互いに当接する当接面１２ｄ，２２ｄを有している（図６及び図７を参照）。   That is, the second vertical frame members 12 and 22 located on the center side of the building opening 2 in the first and second lattice bodies 10 and 20 are respectively the first vertical frame members in the other lattice bodies 20 and 10. 21 and the second vertical frame member 22, and between the first vertical frame member 11 and the second vertical frame member 12, the horizontal beam members 13 and 23 in the lattice bodies 10 and 20 are the other. Are inserted into through holes 24 and 14 provided in the second vertical frame members 22 and 12, respectively, so that both the second vertical frame members 12 and 22 expand both the lattice members 10 and 20 most. The contact surfaces 12d and 22d contact each other in the closed state (see FIGS. 1, 2 and 4) (see FIGS. 6 and 7).

一方、引き違い式の戸障子３が装設された建物開口部２の上横枠及び下横枠における該戸障子３の内側に、上下のガイド枠５，６が固定ネジ５ｂ，６ｂによりそれぞれ固定的に取り付けられ、上記両格子体１０，２０における各縦枠材の上下端部が、該上下のガイド枠５，６のガイド溝５ａ，６ａ（図９〜図１２参照）で形成される同一軌道によりそれぞれ摺動自在に支持されている。従って、面格子４の第１及び第２格子体１０，２０を建物開口部２のガイド枠５，６に沿って相対的に移動させることにより、両格子体１０，２０の設置状態を拡縮することができる。   On the other hand, the upper and lower guide frames 5 and 6 are respectively fixed to the inside of the door frame 3 in the upper horizontal frame and the lower horizontal frame of the building opening 2 where the sliding door 3 is installed by fixing screws 5b and 6b. Fixedly attached, the upper and lower ends of the vertical frame members in the lattice bodies 10 and 20 are formed by guide grooves 5a and 6a (see FIGS. 9 to 12) of the upper and lower guide frames 5 and 6, respectively. They are slidably supported by the same track. Accordingly, the first and second lattice bodies 10 and 20 of the surface lattice 4 are relatively moved along the guide frames 5 and 6 of the building opening 2 to expand and contract the installation state of both the lattice bodies 10 and 20. be able to.

上記上下のガイド枠５，６は、建物開口部２の上横枠及び下横枠の全長にわたって設置されている。これに対して、面格子４を構成する第１及び第２格子体１０，２０は、それらを後述するロック手段５０で連結した拡張状態でも、その面格子４の横方向の長さが、建物開口部２の横幅よりも短く形成されているので、面格子４を最も拡張させた状態においても、後述する固定手段６０により面格子４をガイド枠５，６等に対して固定していなければ、それを該ガイド枠５，６に沿って移動させることができ、もちろん、上記ロック手段５０の解除により第１及び第２格子体１０，２０を個別的に分離したときには、それぞれの格子体１０，２０を個別的に移動させることができる。
なお、格子体１０，２０の移動の必要がなければ、上記ガイド枠５，６の設置範囲を縮小して、格子体１０，２０の移動範囲を制限することもできる。また、上記面格子４は、それを最も拡張させた状態における横幅が、戸障子３のガラス部分の少なくとも大半を覆うように形成するのが望まれる。 The upper and lower guide frames 5 and 6 are installed over the entire length of the upper horizontal frame and the lower horizontal frame of the building opening 2. On the other hand, the first and second lattice bodies 10 and 20 constituting the surface lattice 4 have a lateral length of the surface lattice 4 even in an expanded state in which they are connected by a lock means 50 described later. Since it is formed shorter than the lateral width of the opening 2, even when the surface lattice 4 is expanded most, the surface lattice 4 must be fixed to the guide frames 5, 6, etc. by the fixing means 60 described later. It can be moved along the guide frames 5, 6. Of course, when the first and second lattice bodies 10, 20 are individually separated by releasing the locking means 50, the respective lattice bodies 10 , 20 can be moved individually.
If there is no need to move the lattice bodies 10 and 20, the installation range of the guide frames 5 and 6 can be reduced to limit the movement range of the lattice bodies 10 and 20. Further, it is desirable that the surface lattice 4 is formed so that the width in the state where it is most expanded covers at least most of the glass portion of the door sliding door 3.

上記面格子４は、上述したように、その両格子体１０，２０が拡張された状態でガイド枠６に対して固定する固定手段６０を有しているが、この固定手段６０による面格子４の固定状態においては、両格子体１０，２０の第２縦枠材１２，２２のうちの少なくとも一方が、建物開口部２に装設した上記引き違い式の戸障子３におけるクレセント８の操作子８ａの直前に位置してその操作の障害になり、開錠操作を不能にするように形成されている。   As described above, the surface grid 4 has the fixing means 60 that fixes the grid bodies 10 and 20 to the guide frame 6 in an expanded state. In the fixed state, at least one of the second vertical frame members 12 and 22 of the two lattice bodies 10 and 20 has an operation element for the crescent 8 in the sliding door 3 provided in the opening 2 of the building. It is positioned immediately before 8a to obstruct the operation, and is configured to disable the unlocking operation.

しかしながら、戸障子３を開く場合には、そのクレセント８の解錠操作を行う必要があり、そのため、上述したガイド枠５，６に沿う第１及び第２格子体１０，２０の移動により室内側にクレセント８を露出できるようにして、面格子４がクレセント８の施錠あるいは解錠操作の妨げとならないようにしている。即ち、上記ロック手段５０による第２縦枠材１２，２２の連結の解除及び上記固定手段６０による面格子４の固定の解除により、両格子体１０，２０をガイド枠５，６に沿ってそれぞれ移動可能とした状態において、第２縦枠材１２，２２を上記戸障子３のクレセント８の開錠操作が可能な位置に移動可能に形成している。   However, when the door sliding door 3 is opened, it is necessary to perform the unlocking operation of the crescent 8, and therefore, the indoor side is moved by the movement of the first and second lattice bodies 10 and 20 along the guide frames 5 and 6 described above. Thus, the crescent 8 can be exposed so that the face lattice 4 does not hinder the locking or unlocking operation of the crescent 8. That is, by releasing the connection of the second vertical frame members 12 and 22 by the locking means 50 and releasing the fixation of the surface lattice 4 by the fixing means 60, both the lattice bodies 10 and 20 are respectively moved along the guide frames 5 and 6. In a state where it can move, the second vertical frame members 12, 22 are formed so as to be movable to a position where the unlocking operation of the crescent 8 of the door sliding door 3 can be performed.

上記第１格子体１０及び第２格子体２０の各縦枠材１１，１２，２１，２２は、図２に示すように、それらの上端に設けられた上端キャップ１１ａ，１２ａ，２１ａ，２２ａと、それらの下端に設けられた下端キャップ１１ｂ，１２ｂ，２１ｂ，２２ｂと、これらの各上端及び下端キャップとの間に配設され、上記横桟材１３，２３が取り付けられた中空の中間部材１１ｃ，１２ｃ，２１ｃ，２２ｃとにより構成されている。そして、上記各下端キャップには、下部のガイド枠６におけるガイド溝６ａの口縁の内向き凸条６ｃ（図１１及び図１２参照）との係合により、各縦枠材がガイド溝６ａから抜脱するのを防止するための爪状部３０をそれぞれ突設している（図８参照）。   As shown in FIG. 2, the vertical frame members 11, 12, 21, and 22 of the first lattice body 10 and the second lattice body 20 have upper end caps 11 a, 12 a, 21 a, and 22 a provided on the upper ends thereof. A hollow intermediate member 11c provided between the lower end caps 11b, 12b, 21b, and 22b provided at the lower ends thereof and the upper and lower end caps thereof, to which the crosspieces 13 and 23 are attached. , 12c, 21c, 22c. Each of the lower end caps engages with the inwardly protruding ridge 6c (see FIGS. 11 and 12) of the lip of the guide groove 6a in the lower guide frame 6 so that each vertical frame member extends from the guide groove 6a. Claw-like portions 30 for preventing the removal are respectively protruded (see FIG. 8).

また、上記各中間部材１１ｃ，１２ｃ，２１ｃ，２２ｃは、断面略コ字形状の同一形状の枠部材２５と、その開口部に取り付けられた閉蓋部材２７とでそれぞれ構成され（図６参照）、これら枠部材２５における底面に上記横桟材１３，２３が固定ネジ２９によってそれぞれ固定されている。上記閉蓋部材２７は、上記枠部材２５の開口縁内に嵌め込まれて該開口を閉塞するもので、その側縁に突設された係止爪２７ｂを有する一対の突縁部２７ａを、枠部材２５の両開口縁の凹溝２５ａに嵌入係止させることにより、枠部材１６の開口部に結合させている。更に、上記両第２縦枠材１２，２２の中間部材１２ｃ，２２ｃには、前記貫通穴１４，２４がそれぞれ横桟材２３，１３の断面形状に合わせて開設されている。   Each of the intermediate members 11c, 12c, 21c, and 22c includes a frame member 25 having a substantially U-shaped cross section and a closing member 27 attached to the opening (see FIG. 6). The crosspieces 13 and 23 are fixed to the bottom surfaces of the frame members 25 by fixing screws 29, respectively. The closing member 27 is fitted into the opening edge of the frame member 25 to close the opening, and a pair of protruding edge portions 27a having locking claws 27b protruding from the side edges of the closing member 27 are attached to the frame. By fitting and locking into the concave grooves 25 a at both opening edges of the member 25, the member 25 is coupled to the opening of the frame member 16. Further, the through holes 14 and 24 are formed in the intermediate members 12c and 22c of the second vertical frame members 12 and 22 in accordance with the cross-sectional shapes of the crosspieces 23 and 13, respectively.

上記第２縦枠材１２，２２における枠部材２５には、面格子４を最も拡張した場合に相互に当接する召し合わせ部に前記当接面１２ｄ，２２ｄを形設している（図６及び図７参照）が、両第２縦枠材１２，２２には、第１及び第２格子体１０，２０におけるこれらの当接面１２ｄ，２２ｄの表裏面側を被覆隠蔽するように、それらの当接面１２ｄ，２２ｄの覆片１２ｅ，２２ｅを一体に付設している。従って、当接面相互間にドライバー等の先端を押入してこじ開けたりするの抑止することができる。   The frame members 25 in the second vertical frame members 12 and 22 are formed with the contact surfaces 12d and 22d at the summing portions that contact each other when the surface lattice 4 is expanded most (see FIGS. 6 and 6). 7), both the second vertical frame members 12 and 22 cover and conceal the front and back surfaces of the contact surfaces 12d and 22d of the first and second lattice bodies 10 and 20, respectively. Cover pieces 12e and 22e of the contact surfaces 12d and 22d are integrally provided. Accordingly, it is possible to prevent the tip of a screwdriver or the like from being pushed between the contact surfaces to be opened.

上記第１及び第２格子体１０，２０の横桟材１３，２３は、図１３に示すように、断面縦長の略矩形状のもので、各格子体１０，２０において、全体的に上下方向に略等間隔に配設されると共に、これら格子体１０，２０を組み合わせて成る面格子４において横桟材１３，２３が上下方向に交互に配設されている。そのため、面格子４を拡縮させる際に、両格子体１０，２０の横桟材１３，２３同士が互いに干渉し合うことはない。
そして、各横桟材１３，２３には、第１及び第２縦枠材１１，１２，２１，２２に固定ネジ２９で取り付けるためのビスポケット用溝３３を設け、該溝３３に鉄材またはステンレス製のロープ３４を挿通している。従って、横桟材１３，２３が侵入者によって簡単に破断されることはない。 As shown in FIG. 13, the crosspieces 13 and 23 of the first and second lattice bodies 10 and 20 have a substantially rectangular shape with a vertically long cross section. The crosspieces 13 and 23 are alternately arranged in the vertical direction in the surface lattice 4 formed by combining these lattice bodies 10 and 20. Therefore, when the surface lattice 4 is enlarged or reduced, the crosspieces 13 and 23 of the two lattice bodies 10 and 20 do not interfere with each other.
Each horizontal cross member 13, 23 is provided with a screw pocket groove 33 to be attached to the first and second vertical frame members 11, 12, 21, 22 with a fixing screw 29, and the groove 33 is made of iron or stainless steel. A rope 34 made of steel is inserted. Therefore, the crosspieces 13 and 23 are not easily broken by the intruder.

一方、建物開口部２の上横枠に取り付けられる上記上側ガイド枠５は、図９及び図１０に示すように、下方に向けてガイド溝５ａが開口する断面略コ字形に形成されたものであるが、そのガイド溝５ａの溝底を貫通する固定ネジ５ｂにより上記建物開口部２の上横枠に対して固定される部分の内面に、鉄材またはそれよりも高強度の溝型の補強板３６を当接し、そして、該補強板３６の当接部分を、固定手段６０による面格子４の固定位置において拡張された状態にある両格子体１０，２０の第１及び第２縦枠材１１，１２，２１，２２が存在する部分に設定している。   On the other hand, the upper guide frame 5 attached to the upper horizontal frame of the building opening 2 is formed in a substantially U-shaped cross section in which a guide groove 5a is opened downward as shown in FIGS. On the inner surface of the portion fixed to the upper horizontal frame of the building opening 2 by the fixing screw 5b penetrating the groove bottom of the guide groove 5a, an iron material or a groove-type reinforcing plate higher in strength than that is provided. 36, and the first and second vertical frame members 11 of the two lattice bodies 10 and 20 are in a state where the contact portion of the reinforcing plate 36 is expanded at the fixing position of the surface lattice 4 by the fixing means 60. , 12, 21, 22 are set in the existing portions.

また、建物開口部２の下横枠に取り付けられる上記下側ガイド枠６は、図１１及び図１２に示すように、上方に向けてガイド溝６ａが開口する断面略コ字形に形成されたものであるが、そのガイド溝６ａの溝底を貫通する固定ネジ６ｂにより上記建物開口部２の下横枠に対して固定される部分に、上記補強板３６と同様に、鉄材またはそれよりも高強度の溝型の補強板３７を当接し、そして、上記補強板３６と同様に、補強板３７の当接部分を、固定手段６０による面格子４の固定位置において拡張された状態にある両格子体１０，２０の第１及び第２縦枠材１１，１２，２１，２２が存在する部分に設定している。   Further, the lower guide frame 6 attached to the lower horizontal frame of the building opening 2 is formed in a substantially U-shaped cross section in which a guide groove 6a is opened upward as shown in FIGS. However, in the same manner as the reinforcing plate 36, the iron plate or higher than the reinforcing plate 36 is fixed to the portion fixed to the lower horizontal frame of the building opening 2 by the fixing screw 6b passing through the groove bottom of the guide groove 6a. Both grids are in contact with a strong groove-type reinforcing plate 37, and in the same manner as the reinforcing plate 36, the contacting portion of the reinforcing plate 37 is expanded at the fixing position of the surface lattice 4 by the fixing means 60. The first and second vertical frame members 11, 12, 21, and 22 of the bodies 10 and 20 are set in the portions.

更に、建物開口部２の下横枠に取り付けられる上記下側ガイド枠６は、侵入者によって破壊されやすい位置にあるため、図１２に示すように、この下側ガイド枠６には、その裏側からも、上記補強板３７と同位置に補強板３８を当設し、両補強板３７，３８をネジで固定して一層の補強を図っている
従って、両格子体１０，２０の第１及び第２縦枠材１１，１２，２１，２２がガイド枠５，６に固定される部分が上記補強板３６，３７，３８により補強され、侵入者による破壊を防ぐことができる。 Furthermore, since the lower guide frame 6 attached to the lower horizontal frame of the building opening 2 is in a position where it can be easily destroyed by an intruder, the lower guide frame 6 has a back side as shown in FIG. Therefore, a reinforcing plate 38 is provided at the same position as the reinforcing plate 37, and both the reinforcing plates 37, 38 are fixed with screws to further enhance the reinforcement. The portions where the second vertical frame members 11, 12, 21, 22 are fixed to the guide frames 5, 6 are reinforced by the reinforcing plates 36, 37, 38, and can be prevented from being broken by an intruder.

また、上記下側のガイド枠６は、ガイド溝６ａの溝底の複数箇所において、下横枠に固定ネジ６ｂで固定するようにしているが、それらの固定ネジ６ｂのネジ頭を隠蔽するための細長板状の隠しカバー４０が、該ガイド溝６ａの溝底の幅方向中央部に嵌め込まれている。そして、この隠しカバー４０の取り外しを困難にするため、ガイド枠６の両端側に位置する上記補強板３８の端部を上向きに折返し、上記隠しカバー４０の押さえ片４０ａを形成している。   The lower guide frame 6 is fixed to the lower horizontal frame with fixing screws 6b at a plurality of locations on the bottom of the guide groove 6a. In order to conceal the screw heads of these fixing screws 6b. An elongated plate-like concealed cover 40 is fitted in the central portion in the width direction of the groove bottom of the guide groove 6a. In order to make it difficult to remove the hidden cover 40, the end portions of the reinforcing plate 38 located on both ends of the guide frame 6 are folded upward to form the pressing pieces 40 a of the hidden cover 40.

上述したように、上記面格子４は、その格子体１０，２０を最も拡張させた状態にロックするためのロック手段５０を有している。このロック手段５０は、図１、図６及び図７に示すように、面格子を最も拡張させた状態において相互に当接する第２縦枠材１２及び第２縦枠材２２との間に設けたもので、第２縦枠材２２に取り付けられて、その内部から第２縦枠材１２側に向かって出没するフック５２を操作可能にした錠部５１と、第２縦枠材１２に設けられて、に形成された上記フック５２が係脱可能に係合する係合部５３とを備えている。そして、上記錠部５１は、第２縦枠材２２の中間部材２２ｃの上下２個所に設け、その室内側側面に鍵穴５１ａを有していて、該鍵穴５１ａに差し込んだ鍵の操作により、上記フック５２を上記係合部５３に対し係脱可能に構成している。従って、上記錠部５１を室内側から操作してフック５２を出没させ、係合部５３に対して係脱させることにより、格子体１０，２０における第２縦枠材１２，２２を相互に連結して面格子４を拡張状態に保持したり、またはその連結状態を解除したりすることができる。
なお、上記ロック手段５０は、ここで説明した実施例の構成に限るものではない。 As described above, the surface lattice 4 has the locking means 50 for locking the lattice bodies 10 and 20 in the most expanded state. As shown in FIGS. 1, 6 and 7, the locking means 50 is provided between the second vertical frame member 12 and the second vertical frame member 22 which are in contact with each other in a state where the surface lattice is most expanded. A lock portion 51 that is attached to the second vertical frame member 22 and that can operate a hook 52 that protrudes and protrudes from the inside toward the second vertical frame member 12 side. And the hook 52 formed in is engaged with an engaging portion 53 detachably engaged. And the said lock | rock part 51 is provided in the upper and lower two places of the intermediate member 22c of the 2nd vertical frame material 22, has the keyhole 51a in the room inner side surface, and the said operation is carried out by the operation of the key inserted in this keyhole 51a. The hook 52 is configured to be engageable with and disengageable from the engaging portion 53. Therefore, the second vertical frame members 12 and 22 in the lattice bodies 10 and 20 are connected to each other by operating the lock portion 51 from the indoor side to make the hook 52 protrude and retract and engage / disengage with the engaging portion 53. Thus, the surface lattice 4 can be held in the expanded state, or the connected state can be released.
The locking means 50 is not limited to the configuration of the embodiment described here.

また、上記面格子４には、前述したように、ガイド枠６に対する該面格子４の固定手段６０を備えている。該固定手段６０は、第２縦枠材１２の下部に、ガイド枠６に設けた係止孔６１（図７の（ａ）参照）に向けて突出係合させる係止部材６２を有し、該係止部材６２をガイド枠６の係止孔６１に向けて出没させる操作子６３を、該第２縦枠材１２に上下摺動自在に設けている。この操作子６３は、第１及び第２格子体１０，２０における第２縦枠材１２，２２の当接面側において操作可能に配設されており、そのため、上記ロック手段５０による一対の第２縦枠材１２，２２の連結時には、上記操作子６３が外部から操作不能に隠蔽されることになる。   Further, as described above, the surface lattice 4 includes the fixing means 60 for fixing the surface lattice 4 to the guide frame 6. The fixing means 60 has a locking member 62 that projects and engages with a locking hole 61 (see FIG. 7A) provided in the guide frame 6 at the lower part of the second vertical frame member 12. An operating element 63 for projecting and retracting the locking member 62 toward the locking hole 61 of the guide frame 6 is provided on the second vertical frame member 12 so as to be slidable up and down. The operation element 63 is disposed so as to be operable on the contact surface side of the second vertical frame members 12 and 22 in the first and second lattice bodies 10 and 20. When the two vertical frame members 12 and 22 are connected, the operation element 63 is hidden from the outside so as not to be operated.

従って、上記ロック手段５０を解除した状態で、上記固定手段６０の係止部材６２をガイド枠６の係止孔６１上に移動させ、操作子６３の操作により第２縦枠材１２を下側ガイド枠６に固定した上で、上記ロック手段５０により第２縦枠材１２，２２を連結すると、面格子４を最も拡張させた際に第２縦枠材１２，２２またはそのいずれかが戸障子３のクレセント８の直前に位置する状態に面格子４を固定することができる。
なお、上記固定手段６０については、第１及び第２格子体１０，２０の一方を所定の位置に固定できれば、第１または第２格子体のどちらの格子体に設けてもよい。 Accordingly, in a state where the locking means 50 is released, the locking member 62 of the fixing means 60 is moved onto the locking hole 61 of the guide frame 6, and the second vertical frame material 12 is moved to the lower side by operating the operating element 63. When the second vertical frame members 12 and 22 are connected by the locking means 50 after being fixed to the guide frame 6, the second vertical frame members 12 and 22 or any one of them is a door when the surface lattice 4 is expanded most. The face grid 4 can be fixed in a state located immediately before the crescent 8 of the shoji 3.
The fixing means 60 may be provided on either the first or second lattice body as long as one of the first and second lattice bodies 10 and 20 can be fixed at a predetermined position.
