Therefore, the upper frame 36 and the lower frame 37 of the sliding door 3 are hidden in the grooves 39a and 39b. Further, the walls 40a, 40b on the outdoor side of the grooves 39a, 39b are detachable, and by removing the walls 40a, 40b, the sliding door 3 can be attached to/detached from the outdoor side of the door body 2.
扉本体２は、図１，２に示すように、戸先框２８の吊元側に隣接して、引戸３の一部を引き込むための戸袋部４が設けてある。戸袋部４は、室外側に配置された金属形材４１と、室内側に配置された樹脂形材１３で構成されている。樹脂形材１３は、扉本体２の戸先框２８の室内側面よりも室内側に突出している。また樹脂形材１３は、サムターン３４よりも室内側まで突出している。
As shown in FIGS. 1 and 2, the door body 2 is provided with a door pocket portion 4 adjacent to the suspension base side of the door end frame 28 for retracting a part of the sliding door 3. The door pocket part 4 is composed of a metal shape member 41 arranged on the outdoor side and a resin shape member 13 arranged on the indoor side. The resin shape member 13 projects toward the inside of the door from the inside surface of the door end frame 28 of the door body 2. Further, the resin shape member 13 projects to the indoor side from the thumb turn 34.
本建具は、図１に示すように、引戸３の見付寸法Ａが戸袋部４の見付寸法Ｂよりも大きくなっており、そのため図３と図５（ｂ）に示すように、引戸３を戸袋部４に引き込んだときに、引戸３のガラスパネル５の大部分が戸袋部４から露出する。より詳細には、戸袋部４の見付寸法Ｂは引戸の見付寸法Ａの半分以下としてあり、引戸３を戸袋部４に引き込んだときに、戸袋部４に引き込まれる寸法よりも戸袋部４からはみ出す寸法の方が大きくなっている。そして、引戸３を戸袋部４に引き込むと、図５（ｂ）に示すように、扉１の吊元側に扉本体２の上框２６と下框２７の間の全高さにわたる縦長の換気開口部４２が形成され、当該換気開口部４２を通じて採風・換気が行える。本建具は、そのように引戸３を開けたときに、戸袋部４からはみ出す引戸３の見付寸法Ｃが換気開口部４２の幅Ｄよりも大きくなっている。
換気開口部４２の幅Ｄは、換気が十分可能な寸法であって、人間が頭を入れたり腕を深く差し入れたりするのが困難な寸法に設定してある。「住宅の品質確保の促進等に関する法律」に基づく住宅の性能に関する評価の方法の基準を定めた平成１３年国土交通省告示第１３４７号において、転落防止のための手すりの手すり子の間隔を内法寸法で１１０ｍｍ以下とすることが定められており、本建具の換気開口部４２の幅Ｄは、これにならって１１０ｍｍ以下としている。換気開口部４２の幅Ｄを１１０ｍｍ以下とすることで、万が一にも換気開口部４２から侵入されることはなく、また事前に不正侵入を思い留まらせる効果がある。具体的には、本建具の換気開口部４２の幅Ｄは１００ｍｍとしてあり、上記基準よりもさらに厳しくしてある。
In this fitting, as shown in FIG. 1, the found size A of the sliding door 3 is larger than the found size B of the door pocket portion 4, and therefore, as shown in FIGS. 3 and 5(b), the sliding door 3 When is pulled into the door pocket portion 4, most of the glass panel 5 of the sliding door 3 is exposed from the door pocket portion 4. More specifically, the found size B of the door pocket 4 is half or less than the found size A of the sliding door, and when the sliding door 3 is pulled into the door bag 4, the door pocket 4 is larger than the dimension pulled into the door bag 4. The size that sticks out is larger. Then, when the sliding door 3 is pulled into the door pocket portion 4, as shown in FIG. 5B, a vertically extending ventilation opening extending over the entire height between the upper frame 26 and the lower frame 27 of the door body 2 on the suspension base side of the door 1. The part 42 is formed, and wind and ventilation can be performed through the ventilation opening 42. In this fitting, the found dimension C of the sliding door 3 protruding from the door pocket portion 4 when the sliding door 3 is opened in such a manner is larger than the width D of the ventilation opening 42.
The width D of the ventilation opening 42 is set to a dimension that allows sufficient ventilation, and it is difficult for a person to put his head or his arm deeply. In 2001 Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1347, which established the standard of the method for evaluating the performance of houses based on the "Act on Promotion of Housing Quality Assurance", the interval between the handrails of the handrails to prevent falls was included. It is specified that the normal dimension is 110 mm or less, and the width D of the ventilation opening portion 42 of the fitting is 110 mm or less accordingly. By setting the width D of the ventilation opening 42 to 110 mm or less, it is possible to prevent entry from the ventilation opening 42 by any chance, and to prevent unauthorized entry in advance. Specifically, the width D of the ventilation opening 42 of the fitting is 100 mm, which is more strict than the above standard.
以上に述べたように本建具は、框組みした扉本体２内に引戸３を左右方向にスライド可能に組み込み、一方の縦框（戸先框２８）に隣接して戸袋部４を設けてあり、引戸３の見付寸法Ａが戸袋部４の見付寸法Ｂより大きく、引戸３を戸袋部４に引き込んだときにパネル（ガラスパネル５）が戸袋部４から露出するため、換気時の開口部４２の幅Ｄを狭くして、不審者の侵入や不正解錠を防ぐことができる。換気開口部４２は、扉１の戸先側に形成されるようにしてもよいが、本実施形態のように扉１の吊元側に換気開口部４２が形成されるようにすることで、換気開口部４２から戸先框２８のサムターン３４へのアクセスが困難になるため、防犯性が高くなる。
さらに本建具は、戸袋部４を構成する室内側の樹脂形材１３が戸先框２８の室内側面よりも室内側に突出しており、さらに樹脂形材１３はサムターン３４よりも室内側に突出していることで、樹脂形材１３が障壁となって室外からサムターン３４の位置を視認することができず、また、換気開口部４２から針金などを差し入れてサムターン３４を操作することも困難であり、防犯性がより一層向上する。
換気開口部４２は、扉１の上框２６から下框２７までの間全体が開口するため、幅が狭くても十分な換気が行え、重力換気も効率よく行える。本建具は、戸袋部４の見付寸法Ｂを引戸３の見付寸法Ａと比べて小さくしたことで、扉１全体に占める断熱性に優れたガラスパネル５の面積の割合を大きくでき、上げ下げ窓のような召合せ部も無いため、断熱性能を向上することができ、また、採光性にも優れる。さらに、引戸３が一部しか開かないことで、小雨程度なら引戸３を開けたままでも雨が入りにくく、採光・断熱・止水の３つをバランス良く向上させられ、建具としての性能が総合的に優れている
As described above, in this fitting, the sliding door 3 is slidably incorporated in the door main body 2 assembled in the frame, and the door pocket portion 4 is provided adjacent to one vertical frame (the door frame 28). , The sliding door 3 has a found dimension A larger than the found portion B of the door pocket portion 4, and when the sliding door 3 is pulled into the door pocket portion 4, the panel (glass panel 5) is exposed from the door pocket portion 4, so that the opening for ventilation is provided. By narrowing the width D of the portion 42, it is possible to prevent a suspicious person from entering and unlocking illegally. The ventilation opening 42 may be formed on the door tip side of the door 1, but by forming the ventilation opening 42 on the hanging side of the door 1 as in the present embodiment, Since it becomes difficult to access the thumb turn 34 of the door frame 28 from the ventilation opening 42, the crime prevention performance is enhanced.
Further, in this fitting, the resin shape member 13 on the indoor side that constitutes the door pocket part 4 projects more toward the indoor side than the indoor side surface of the door end frame 28, and the resin shape member 13 projects further toward the indoor side than the thumb turn 34. Since the resin shape member 13 serves as a barrier, the position of the thumb turn 34 cannot be visually recognized from outside the room, and it is also difficult to insert the wire or the like from the ventilation opening 42 to operate the thumb turn 34. The crime prevention is further improved.
Since the entire ventilation opening 42 is opened from the upper frame 26 to the lower frame 27 of the door 1, sufficient ventilation can be performed even if the width is narrow, and gravity ventilation can be efficiently performed. In this fitting, by making the finding size B of the door pocket part 4 smaller than the finding size A of the sliding door 3, it is possible to increase the ratio of the area of the glass panel 5 having excellent heat insulating property to the entire door 1, and raise/lower it. Since there is no assembling part such as a window, the heat insulation performance can be improved and the lighting is excellent. Furthermore, since the sliding door 3 is only partially opened, it is difficult for rain to enter even if the sliding door 3 is open even if it is light rain, and it is possible to improve the lighting, heat insulation, and water blocking in a well-balanced manner, and the performance as a fitting is comprehensive. Is excellent
本建具は、引戸３を換気可能な分だけ開け閉めするために、引戸開閉装置７を備えている。本建具は、枠（框組体６）と、引戸３と、引戸開閉装置７を備え、引戸開閉装置７は、引戸３を開けたときに換気開口部４２ができる側と反対側（引戸３にとっての戸尻側）に設けてあり、枠に設けた回動可能なレバー８と、レバー８の軸４３に固定した第１アーム９と、第１アーム９の先端部と引戸３とに連結した第２アーム１０を有し、第１アーム９と第２アーム１０とが屈曲状態のときに引戸３が開き、レバー８の回動操作により第１アーム９と第２アーム１０とが展開状態になると引戸３が閉じるようになっている。具体的には、引戸開閉装置７は、図２と図７に示すように、扉本体２の戸先框２８の室内側に設けた回動可能なレバー８と、レバー８の軸４３に固定した第１アーム９と、第１アーム９の先端部と引戸３とに連結した第２アーム１０を備えている。
図７（ａ）に示すように、第１アーム９と第２アーム１０とが展開状態のときには引戸３は閉じており、図７（ｂ）に示すように、レバー８を時計方向に９０°回動すると、第１アーム９と第２アーム１０とが屈曲状態となり、これに伴い引戸３は第２アーム１０に引っ張られて開く。このように本建具は、引戸３に触れることなく、レバー８を回動操作するだけで、引戸３を換気可能な分だけ簡便に開け閉めできる。
This fitting includes a sliding door opening/closing device 7 for opening and closing the sliding door 3 by an amount that allows ventilation. This fitting includes a frame (frame assembly 6), a sliding door 3, and a sliding door opening/closing device 7. The sliding door opening/closing device 7 is opposite to a side (a sliding door 3 where a ventilation opening 42 is formed when the sliding door 3 is opened). And a first arm 9 fixed to a shaft 43 of the lever 8, and a tip end portion of the first arm 9 and the sliding door 3. The second arm 10 is provided, and the sliding door 3 is opened when the first arm 9 and the second arm 10 are in the bent state, and the first arm 9 and the second arm 10 are in the expanded state by the turning operation of the lever 8. When, the sliding door 3 is closed. Specifically, as shown in FIGS. 2 and 7, the sliding door opening/closing device 7 is fixed to a rotatable lever 8 provided on the indoor side of the door frame 28 of the door body 2 and a shaft 43 of the lever 8. It has a first arm 9 and a second arm 10 connected to the tip of the first arm 9 and the sliding door 3.
As shown in FIG. 7A, the sliding door 3 is closed when the first arm 9 and the second arm 10 are in the deployed state, and as shown in FIG. 7B, the lever 8 is rotated clockwise by 90°. When rotated, the first arm 9 and the second arm 10 are bent, and accordingly, the sliding door 3 is pulled by the second arm 10 and opened. In this way, the present fitting can simply open and close the sliding door 3 as much as it can be ventilated by simply rotating the lever 8 without touching the sliding door 3.
レバー８にはＬ形に曲がった形状のロック片４４が内蔵してあると共に、ロック片４４を室外向きに付勢する板バネ４５と、ロック片４４を室内向きに操作するための操作部４６を有している。レバー８から手を離した状態では、ロック片４４がレバー８の台座４７に設けた穴４８に係合し、レバー８の回動が規制されている。そのため、図７（ａ）に示すように、レバー８が横になった状態では引戸３が閉位置に保持され、図７（ｂ）に示すように、レバー８が縦になった状態では引戸３が開位置に保持されており、扉１を開閉したときに引戸３が遠心力によりスライドすることがない。レバー８を回動操作するためにレバー８を手で掴むと、図９（ｃ）に示すように、操作部４６が押し込まれてロック片４４が板バネ４５に抗して室内側に移動し、レバー台座４７の穴４８から抜けるので、特別な解除操作を行うことなく自然にレバー８を回動操作できる。なお、上述したレバー８のロック機構は、レバー８を引戸３が開いたときの位置と引戸３が閉じたときの位置の少なくとも何れか一方の位置でロックできるものであればよい。
The lever 8 has a lock piece 44 that is bent in an L-shape and is built in. A leaf spring 45 that urges the lock piece 44 outward and an operation portion 46 that operates the lock piece 44 indoors. have. When the lever 8 is released, the lock piece 44 engages with the hole 48 formed in the pedestal 47 of the lever 8 and the rotation of the lever 8 is restricted. Therefore, as shown in FIG. 7A, the sliding door 3 is held in the closed position when the lever 8 is in the horizontal position, and when the lever 8 is in the vertical position as shown in FIG. 7B. 3 is held in the open position, and the sliding door 3 does not slide due to centrifugal force when the door 1 is opened and closed. When the lever 8 is gripped by hand to rotate the lever 8, as shown in FIG. 9C, the operating portion 46 is pushed in and the lock piece 44 moves to the indoor side against the leaf spring 45. Since it is pulled out from the hole 48 of the lever pedestal 47, the lever 8 can be naturally rotated without performing a special releasing operation. The above-described lock mechanism of the lever 8 may be any mechanism that can lock the lever 8 in at least one of the position when the sliding door 3 is opened and the position when the sliding door 3 is closed.
