As shown in FIGS. 1 and 3, the sliding door 14 is constructed by assembling an upper frame 39, a lower frame 40, a door end frame 18, and a door sill frame 19 and inserting a glass panel 41 inside thereof. .. Each of the frames 39, 40, 18, 19 is configured by connecting metal shape members 39a, 40a, 18a, 19a arranged on the outdoor side and resin shape members 39b, 40b, 18b, 19b arranged on the indoor side. I am doing it. The glass panel 41 uses double glazing having excellent heat insulating properties. As shown in FIG. 3, the hanging door wheel 7 is attached to the metal frame member 39a of the upper frame 39, and the downwardly opening groove 34 is formed in the metal frame member 40a of the lower frame 40. By engaging the upper rails 32 of the upper frame 30 of the door body 21 and the grooves 34 of the lower frame 40 with the guide rollers 35 of the lower frame 31 of the door body 21 so that the sliding door 14 can move the door of the door body 21. It is supported so as to be slidable in the left-right direction between the inner peripheral side edges of the front frame 17 and the suspension frame 16.
As shown in FIG. 3, the lower edge of the upper frame 39 of the sliding door 14 is at the same height as the lower edge of the upper frame 30 of the door body 21 and the upper frame auxiliary member 33, and the lower frame 40 of the lower door 40 of the sliding door 14. The upper edge has the same height as the upper edge of the lower frame 31 and the lower frame auxiliary member 36 of the door body 21. Therefore, the upper frame 39 and the lower frame 40 of the sliding door 14 are completely hidden by the upper frame 30 and the lower frame 31 of the door body 21 when viewed from the outside and the indoor side.
戸本体２１は、図１，２に示すように、戸先框１７の吊元側に隣接して、引戸１４の一部を引き込むための戸袋部４２が設けてある。戸袋部４２は、室外側に配置された金属形材４３及び機能枠３の縦枠４４と、室内側に配置された樹脂形材４５で構成されている。樹脂形材４５は、戸本体２１の戸先框１７の室内側面よりも室内側に突出している。
As shown in FIGS. 1 and 2, the door body 21 is provided with a door pocket portion 42 adjacent to the suspension base side of the door frame 17 for retracting a part of the sliding door 14. The door pocket part 42 is composed of a metal profile 43 and a vertical frame 44 of the functional frame 3 arranged on the outdoor side, and a resin profile 45 arranged on the indoor side. The resin shape member 45 protrudes more toward the room side than the room side surface of the door frame 17 of the door body 21.
図１に示すように、引戸１４の戸尻框１９の内周側縁は、戸袋部４２の内周側縁と同じ位置になっており、したがって戸尻框１９は室外側及び室内側から見て戸袋部４２に完全に隠れている。一方、引戸１４の戸先框１８は、室外側及び室内側から見てほぼ全体が露出している。引戸１４の開閉操作は、戸先框１８の室内側面に設けた引手４６に手を掛けて行う。
引戸１４の戸先框１８が戸本体２１の吊元框１６に隠れていたとすると、引戸１４を閉鎖した状態から戸先框１８の見付寸法分だけスライドしてからでないと換気用開口部２５が形成されず、引戸１４の全スライド量に対して戸先框１８の見付寸法分だけ換気用開口部２５の幅が狭くなってしまう。例えば、引戸１４の全スライド量が１００ｍｍで戸先框１８の見付寸法が５０ｍｍであったとすると、換気用開口部２５の幅は５０ｍｍにしかならない。本建具は、引戸１４の戸先框１８が室外側及び室内側から見てほぼ全体が露出していることで、引戸１４を閉鎖した状態からスライドさせるとすぐに換気用開口部２５が形成され、引戸１４の全スライド量のほぼ全部を換気用開口部２５とすることができる。これにより、引戸１４の全スライド量が小さい場合でも換気用開口部２５を可能な限り広くすることができ、換気の効率が良い。戸先框１８以外の三方の框（上框３９、下框４０、戸尻框１９）は、戸本体２１の框３０，３１や戸袋部４２で隠れているため、断熱性、意匠性が良い。
As shown in FIG. 1, the inner peripheral side edge of the door sill frame 19 of the sliding door 14 is located at the same position as the inner peripheral side edge of the door pocket portion 42. Therefore, the door sill frame 19 is viewed from the outside and the inside of the room. Completely hidden in the door pocket 42. On the other hand, the door end frame 18 of the sliding door 14 is almost entirely exposed when viewed from the outside and the inside of the room. The opening/closing operation of the sliding door 14 is performed by placing a hand on a pull tab 46 provided on the indoor side surface of the door frame 18.
If the door frame 18 of the sliding door 14 is hidden by the hanging frame 16 of the door body 21, the ventilation opening 25 must be moved from the closed state of the sliding door 14 by the amount found by the door frame 18. Is not formed, and the width of the ventilation opening 25 is narrowed by the found dimension of the door frame 18 with respect to the total sliding amount of the sliding door 14. For example, if the sliding amount of the sliding door 14 is 100 mm and the found dimension of the door frame 18 is 50 mm, the width of the ventilation opening 25 is only 50 mm. In this fitting, since the door frame 18 of the sliding door 14 is exposed almost entirely when viewed from the outside and the inside of the room, the ventilation opening 25 is formed immediately when the sliding door 14 is slid from the closed state. Almost all of the sliding amount of the sliding door 14 can be used as the ventilation opening 25. Thereby, even if the total sliding amount of the sliding door 14 is small, the ventilation opening 25 can be made as wide as possible, and the ventilation efficiency is good. The three frames (upper frame 39, lower frame 40, Tojiri frame 19) other than the door frame 18 are hidden by the frames 30 and 31 of the door body 21 and the door pocket part 42, and thus have good heat insulation and design. ..
本建具は、図１に示すように、引戸１４の見付寸法Ａが戸袋部４２の見付寸法Ｂよりも大きくなっており、そのため図２と図４（ｂ）に示すように、引戸１４を戸袋部４２に引き込んだときに、引戸１４のガラスパネル４１の大部分が戸袋部４２から露出する。より詳細には、戸袋部４２の見付寸法Ｂは引戸１４の見付寸法Ａの半分以下としてあり、引戸１４を戸袋部４２に引き込んだときに、戸袋部４２に引き込まれる寸法よりも戸袋部４２からはみ出す寸法の方が大きくなっている。そして、引戸１４を戸袋部４２に引き込むと、図４（ｂ）に示すように、戸２の吊元側に戸本体２１の上框３０と下框３１の間の全高さにわたる縦長の換気用開口部２５が形成され、当該換気用開口部２５を通じて採風・換気が行える。本建具は、そのように引戸１４を開けたときに、戸袋部４２からはみ出す引戸１４の見付寸法Ｃが換気用開口部２５の幅Ｄよりも大きくなっている。
換気用開口部２５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、本建具の換気用開口部２５の幅Ｄは、これにならって１１０ｍｍ以下としている。換気用開口部２５の幅Ｄを１１０ｍｍ以下とすることで、万が一にも換気用開口部２５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、本建具の換気用開口部２５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 14 is larger than the found size B of the door pocket part 42, and therefore, as shown in FIG. 2 and FIG. When is pulled into the door pocket portion 42, most of the glass panel 41 of the sliding door 14 is exposed from the door pocket portion 42. More specifically, the found size B of the door pocket part 42 is half or less than the found size A of the sliding door 14, and when the sliding door 14 is retracted into the door bag part 42, it is smaller than the dimension drawn into the door bag part 42. The size protruding from 42 is larger. Then, when the sliding door 14 is pulled into the door pocket portion 42, as shown in FIG. 4B, a vertically long ventilation for the entire height between the upper frame 30 and the lower frame 31 of the door body 21 is provided on the hanging side of the door 2. The opening 25 is formed, and air can be taken and ventilated through the ventilation opening 25. In the fitting, the found dimension C of the sliding door 14 protruding from the door pocket portion 42 when the sliding door 14 is opened is larger than the width D of the ventilation opening 25.
The width D of the ventilation opening 25 is set to a dimension that allows sufficient ventilation, and it is difficult for a human to put his head or his arm deeply. In 2001 Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1347, which established the criteria for the method of evaluating the performance of houses based on the "Act on Promotion of Housing Quality Assurance", the intervals between the handrails of the handrails to prevent falls are included. It is specified that the normal dimension is 110 mm or less, and the width D of the ventilation opening 25 of the fitting is 110 mm or less. By setting the width D of the ventilation opening 25 to 110 mm or less, it is possible to prevent entry from the ventilation opening 25 by any chance, and also to prevent unauthorized entry in advance. Specifically, the width D of the ventilation opening 25 of the fitting is 100 mm, which is more strict than the above standard.
引戸１４の見付寸法Ａは、戸先框１７と吊元框１６の内周側端縁間の寸法から必要な換気用開口部２５の幅Ｄを減じた寸法となっており、戸袋部４２の見付寸法Ｂは、引戸戸尻框１９の見付寸法と必要な換気用開口部２５の幅Ｄを合計した寸法となっている。これにより、引戸戸尻框１９を隠し框としながら、必要な換気用開口部２５の幅Ｄを容易に設定でき、設計自由度を向上できる。また、戸袋部４２の見付寸法Ｂを最小のものにすることができ、意匠性を向上できると共に戸袋部４２の材料費を削減でき、さらに戸袋部４２の内周側端縁のふらつきを防止できる。また、換気用開口部２５の幅Ｄを増減した商品を設定する場合には、戸袋部４２を見付けの異なるものに変更すると共に、引戸１４の幅を増減するだけでよく、換気用開口部２５の幅Ｄの異なるバリエーションの拡充を容易に行うことができる。
The found dimension A of the sliding door 14 is a dimension obtained by subtracting the required width D of the ventilation opening 25 from the dimension between the inner peripheral side edges of the door frame 17 and the suspension frame 16, and the door pocket part 42. The found size B is the sum of the found size of the sliding door buttocks frame 19 and the necessary width D of the ventilation opening 25. Thereby, the required width D of the ventilation opening 25 can be easily set, and the degree of freedom in designing can be improved, while the sliding door buttocks sill 19 is hidden. Further, the finding size B of the door pocket portion 42 can be minimized, the designability can be improved, the material cost of the door pocket portion 42 can be reduced, and the fluctuation of the inner peripheral side edge of the door pocket portion 42 can be prevented. it can. Further, when setting a product in which the width D of the ventilation opening 25 is increased or decreased, it is only necessary to change the door pocket 42 to a different one and to increase or decrease the width of the sliding door 14, and the ventilation opening 25 It is possible to easily expand variations having different widths D.
このように本建具は、框組みした戸本体２１内に引戸１４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１７）に隣接して戸袋部４２を設けてあり、引戸１４の見付寸法Ａが戸袋部４２の見付寸法Ｂより大きく、引戸１４を戸袋部４２に引き込んだときにガラスパネル４１が戸袋部４２から露出するため、換気時の開口部の幅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。換気用開口部２５は、戸２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戸２の吊元側に換気用開口部２５が形成されるようにすることで、換気用開口部２５から戸先框１７のサムターン４７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４２を構成する室内側の樹脂形材４５が戸先框１７の室内側面よりも室内側に突出していることで、樹脂形材４５が障壁となって室外からサムターン４７の位置を視認することができず、また、換気用開口部２５から針金などを差し入れてサムターン４７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。
換気用開口部２５は、戸２の上框３０から下框３１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４２の見付寸法Ｂを引戸１４の見付寸法Ａと比べて小さくしたことで、戸全体に占める断熱性に優れたガラスパネル４１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１４が一部しか開かないことで、小雨程度なら引戸１４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 14 is slidably installed in the left-right direction in the frame body 21 assembled with the frame, and the door pocket portion 42 is provided adjacent to one vertical frame (the door frame 17). Has a larger dimension A than the dimension B of the door pocket portion 42, and the glass panel 41 is exposed from the door pocket portion 42 when the sliding door 14 is pulled into the door pocket portion 42, so the width D of the opening portion during ventilation is narrowed. Thus, it is possible to prevent a suspicious person from invading or being unlocked illegally. The ventilation opening 25 may be formed on the door end side of the door 2, but the ventilation opening 25 should be formed on the hanging side of the door 2 as in the present embodiment. Since it becomes difficult to access the thumb turn 47 of the door frame 17 from the ventilation opening 25, the crime prevention performance is enhanced.
Further, in the present fitting, since the resin shape member 45 on the indoor side that constitutes the door pocket portion 42 protrudes more toward the room side than the indoor side surface of the door frame 17, the resin shape member 45 serves as a barrier from the outside to the thumb turn 47. Is not visible, and it is also difficult to insert a wire or the like through the ventilation opening 25 to operate the thumb turn 47, which further improves crime prevention.
The ventilation opening 25 is entirely opened between the upper frame 30 and the lower frame 31 of the door 2, so that sufficient ventilation can be performed even if the width is narrow, and gravitational ventilation can be efficiently performed. In this fitting, by making the finding size B of the door pocket part 42 smaller than the finding size A of the sliding door 14, it is possible to increase the ratio of the area of the glass panel 41 having excellent heat insulating property to the entire door, and to raise and lower the window. Since there is no assembling part like the above, the heat insulation performance can be improved and the daylighting property is excellent. Furthermore, since the sliding door 14 is only partially opened, it is difficult for rain to enter even if the sliding door 14 is open even if it is a light rain, and the three aspects of daylighting, heat insulation, and water blocking can be improved in a well-balanced manner, and the performance as a fitting is comprehensive. Is excellent.

Next, a procedure for attaching the functional frame 3 will be described. First, as shown in FIG. 7-1(a), the sliding door 14 is incorporated into the door main body 21, and the height of the wheels 9 of the hanging door vehicle 7 and the height of the stopper 69 are adjusted. The upper frame auxiliary member 33 and the lower frame auxiliary member 36 are attached to the outdoor side of the upper frame 30 and the lower frame 31 with screws 76. At this time, the upper end of the tight member 61a provided outside the hanging frame 16 of the door body 21 is the tight member 61c provided on the upper frame auxiliary member 33, and the lower end is the tight member 61d provided on the lower frame auxiliary member 36. Make sure they touch.
Next, as shown in FIGS. 7-2(c) and 8(a), the engaged portion 5 of the functional frame 3 is engaged with the engaging portion 4 of the door main body 21 from the hanging side. At this time, the notch 51 provided in the engaged portion 5 on the door tip side of the functional frame 3 is engaged with the retaining member 52 provided in the engaging portion 4 of the door body 21, whereby the functional frame 3 is Positioned vertically. Further, the upper end of the tight member 61b provided on the indoor side of the vertical frame 44 on the door end side of the functional frame 3 is the tight member 61c provided on the upper frame auxiliary member 33, and the lower end is the tight member provided on the lower frame auxiliary member 36. 61d respectively.
Then, as shown in FIG. 8B and FIG. 9, with the door 2 opened, the finding piece 55 of the fixture 6 is inserted into the hole 57 provided in the vertical frame 48 on the hanging side of the functional frame 3. Then, the prospective piece 56 of the fixture 6 is fixed to the prospective surface 58 on the hanging side of the door 1 with the screw 59.
以上に述べたように本建具は、機能枠３の一方側（戸先側）に長手方向に設けた被係合部５が、戸２の一方側に長手方向に設けた溝状の係合部４と係合して見込方向に位置決めされるとともに、被係合部５が係合部４内で長手方向に位置決めしてあることで、機能枠３の一方側をバール等で戸２から外すことが困難であり、機能枠３の他方側（吊元側）の端部には固定具６を有し、固定具６は、戸枠１と戸２の見込面間の隙間に挿入し、戸２の見込面５８にねじ止めしてあるため、戸２を閉めた状態では固定具６のねじ５９を外すことができないため、機能枠３が不正に取り外されるのを確実に防止できる。
本建具は、戸２を開いた状態で固定具６を機能枠３に係脱自在であり、戸２を閉めると固定具６の戸２へのねじ止め部が戸枠１と戸２の間に隠れるので、戸２を開けた状態にすれば機能枠３の着脱が容易に行え、戸２を閉めた状態では機能枠３が不正に取り外されるのを確実に防止できる。

機能枠３は、一方側と他方側が上枠７７と下枠７８よりも長辺の縦枠４４，４８になっており、撓みが生じやすい長辺側（縦枠４４，４８）のみで戸２に取付いており、短辺側（上枠７７及び下枠７８）を戸２に固定する必要がないので、機能枠３を取付けるための部品を削減でき、機能枠３の取付けが簡単に、しかも強固に行える。
特に本建具は、機能枠３を戸２の吊元側から戸２と係合し、戸２の吊元側の見込面５８に固定具６をねじ止めしており、戸２の吊元側は蝶番２４で縦枠２８ｂに固定されているので変形しづらいため、固定具６のねじ５９を外すことが一層困難であるから、防犯性が向上する。
As described above, in this fitting, the engaged portion 5 provided in one side (door tip side) of the functional frame 3 in the longitudinal direction has the groove-like engagement provided in one side of the door 2 in the longitudinal direction. Since the engaged portion 5 is positioned in the prospective direction by engaging with the portion 4 and the engaged portion 5 is positioned in the engaging portion 4 in the longitudinal direction, one side of the functional frame 3 is removed from the door 2 by a bar or the like. It is difficult to remove, and the other end (suspension side) of the functional frame 3 has a fixture 6, and the fixture 6 is inserted in the gap between the prospective surfaces of the door frame 1 and the door 2. Since it is screwed to the prospective surface 58 of the door 2, the screw 59 of the fixture 6 cannot be removed when the door 2 is closed, so that the functional frame 3 can be reliably prevented from being unlawfully removed.
In this fitting, the fixture 6 can be freely engaged with and disengaged from the functional frame 3 with the door 2 opened, and when the door 2 is closed, the screwing portion of the fixture 6 to the door 2 is between the door frame 1 and the door 2. Since the function frame 3 can be easily attached and detached when the door 2 is opened, it is possible to reliably prevent the function frame 3 from being illegally removed when the door 2 is closed.
Since the fixture 6 is inserted into the hole 57 provided in the functional frame 3 from the other side, even if the position of the edge on the other side of the functional frame 3 is slightly different due to an error or the like, the fixture 6 is inserted into the hole 57. It can be fixed without any problem simply by changing the length. Moreover, since the fixture 6 is a separate body from the functional frame 3, it is easy to carry.
The functional frame 3 has vertical frames 44 and 48 on one side and the other side that are longer sides than the upper frame 77 and the lower frame 78, and the door 2 is provided only on the long side (vertical frames 44 and 48) where bending easily occurs. Since it is not necessary to fix the short sides (the upper frame 77 and the lower frame 78) to the door 2, the number of parts for mounting the functional frame 3 can be reduced, and the functional frame 3 can be easily mounted. It can be done firmly.
Particularly, in this fitting, the functional frame 3 is engaged with the door 2 from the hanging side of the door 2, and the fixing tool 6 is screwed to the prospective surface 58 on the hanging side of the door 2, and the hanging side of the door 2 Since it is fixed to the vertical frame 28b by the hinge 24 and is difficult to deform, it is more difficult to remove the screw 59 of the fixing tool 6, and thus the crime prevention performance is improved.

傾斜面１３ａ，１３ｂは、内ハウジング１０と調整具１２の何れか一方にだけ設けてもよいが、内ハウジング１０と調整具１２の両方に傾斜面１３ａ，１３ｂを設け、傾斜面１３ａ，１３ｂ同士が当接するようにしたことで、より確実に調整力を面で伝達することができ、安定した調整を行うことができる。
外ハウジング８に見込片７３を有し、調整具１２の内ハウジング１０と反対側の面（上面）が外ハウジング８の見込片７３に当接していることで、調整具１２に加わる引戸１４の荷重を調整ねじ１１に負担させることを回避でき、見込片７３で引戸１４の荷重を負担できるので、安定して引戸１４を支持できると共に、調整ねじ１１の破損や変形を防止できる。
さらに本吊り戸車７は、車輪９がレール３２から外れるのを防ぐ外れ止め６９を備え、外れ止め６９を固定するねじ７４が調整ねじ１１と同じ外ハウジング８の室外側の見付面７１に設けてあるので、外れ止め６９の調整も室外側から行うことができ、都合がよい。
内ハウジング１０には、車輪９の左右両側に調整具１２と当接する傾斜面１３ａが設けてあることで、内ハウジング１０が両側から安定して支持されるため、調整状態を安定して維持できると共に、引戸１４の円滑な開閉を実現できる。
本建具は、引戸１４が戸本体２１内に組み込まれており、引戸１４の全スライド量も１００ｍｍ程度と小さいため、引戸１４の側方から戸車７の車輪９の高さ調整を行うことが困難であるが、この吊り戸車７を採用したことで、戸車７の車輪９の高さ調整が室外側から行えるので、引戸１４の設置状況如何にかかわらず車輪９の高さ調整が容易に行える。
