Description

本発明は、開口枠に対し開閉可能に取付けられた片開き窓、たてすべり出し窓や片開きドアの障子の負圧受け部材およびそれを備えた開き窓に関する。 The present invention relates to a negative pressure receiving member for a single-leaf window, a vertical sliding window or a single-leaf door that is attached to an opening frame so that it can be opened and closed, and a single-leaf window that is equipped with the same.

開き窓の戸先(開口枠)側には、障子側に設けられた錠装置の締まり金具やラッチ(以下、ロックピンと総称する。)を係止する受け部材が設けられている(例えば、特許文献1参照。)。 A receiving member is provided on the door end (opening frame) side of the hinged window to engage the fastening hardware and latch (hereinafter collectively referred to as the lock pin) of the locking device provided on the shoji side (see, for example, Patent Document 1).

また、開き窓の吊元側には、障子を閉めた状態において強風等によって室外側が負圧になって障子全体が室外側に湾曲して障子が外れたり、水密性や気密性が低下することを防止するため、負圧受け部材を設けている(例えば、特許文献2参照。)。 In addition, on the hinged side of the casement window, a negative pressure receiving member is provided to prevent the outside of the room from becoming negative pressure due to a strong wind or other factors when the screen is closed, causing the entire screen to bend toward the outside of the room, resulting in it coming off or reducing its watertightness or airtightness (see, for example, Patent Document 2).

しかし、最近は台風等が大型化して障子にかかる負圧が大きくなっていると共に、最近のサッシのデザイン面等から障子の框の見付け方向の幅が狭くなって框の強度が低下しているため、上記特許文献1の戸先側の受け部材や上記特許文献2の負圧受け部材では十分でないおそれがある。 However, in recent years, typhoons and other events have become larger, increasing the negative pressure on the shoji screens. At the same time, recent sash designs have narrowed the width of the shoji screen frame in the viewing direction, reducing the strength of the frame. As a result, the support member on the door end side in Patent Document 1 and the negative pressure support member in Patent Document 2 may not be sufficient.

そこで、本発明はこのような問題点に着目してなされたもので、大きい負圧に確実に耐えることができる負圧受け部材および開き窓を提供することを目的とする。 Therefore, the present invention was made with a focus on these problems, and aims to provide a negative pressure receiving member and a hinged window that can reliably withstand large negative pressures.

Note that here, the fixed plate portion 23a and the protruding locking piece 23c are configured as a single unit.

(錠受け金具3)
錠受け金具3は、図2や図3等に示すように、開口枠11の戸先側の縦枠11dに固定されて、施解錠機構2のロック金具23が係止する金具であって、図5(a)~(c)および図6(a),(b)に示すように、錠受け金具本体31と、本実施形態では錠受け金具本体31に4本のビス33で固定された錠受け金具補助体32とで構成される。
(Lock bracket 3)
As shown in Figures 2 and 3, the lock receiving hardware 3 is a hardware that is fixed to the vertical frame 11d on the door end side of the opening frame 11 and engages the locking hardware 23 of the locking/unlocking mechanism 2, and as shown in Figures 5(a) to (c) and 6(a) and (b), it is composed of a lock receiving hardware main body 31 and, in this embodiment, a lock receiving hardware auxiliary body 32 fixed to the lock receiving hardware main body 31 with four screws 33.

(錠受け金具本体31)
錠受け金具本体31は、図5(b)に示すように鉛直方向に延びる鉛直板部31aと、鉛直板部31aの上下からそれぞれ水平方向で、かつ、開口枠11の戸先側の縦枠11dに固定した際には図3等に示すように障子12から少しずつ離れるように傾斜して延びる水平板部31b,31bとから正面視、コ字形状に形成されている。
(Lock receiving metal fitting body 31)
The lock receiving hardware main body 31 is formed in a U-shape when viewed from the front, consisting of a vertical plate portion 31a extending vertically as shown in Figure 5 (b) and horizontal plate portions 31b, 31b which extend horizontally from the top and bottom of the vertical plate portion 31a and which, when fixed to the vertical frame 11d on the door end side of the opening frame 11, extend at an angle so as to gradually move away from the shoji screen 12 as shown in Figure 3, etc.

鉛直板部31aには、図5(b)に示すようにその上下にそれぞれ後述する連動プレート26にビス34(図3等参照。)で固定するためほぼ45度の角度で傾斜した傾斜長孔31a1,31a1が設けられていると共に、その中央には鉛直板部31aの中央から突出した後、90度前後折り曲げて起こされ、開口枠11の戸先側の縦枠11dに固定した際には図3等に示すように障子12側に向かって延び、錠受け金具3の施錠時に施解錠機構2の第1係止部としてのロックピン23bを受ける第1受け部としてのロックピン受け部31a2が設けられている。 As shown in FIG. 5(b), the vertical plate portion 31a has oblong holes 31a1, 31a1 at an angle of approximately 45 degrees on the top and bottom for fixing to the interlocking plate 26 described later with screws 34 (see FIG. 3, etc.), and in the center is a lock pin receiving portion 31a2 that protrudes from the center of the vertical plate portion 31a, is bent and raised by approximately 90 degrees, and extends toward the shoji screen 12 side as shown in FIG. 3 when fixed to the vertical frame 11d on the door end side of the opening frame 11, and receives the lock pin 23b as the first engagement portion of the locking/unlocking mechanism 2 when the lock receiving hardware 3 is locked.

ロックピン受け部31a2の上下両端部は、図5(b)等に示すように鉛直板部31aから離れる方向に45度ずつ曲げられており、ロックピン23bを円滑かつ確実に受けるように構成されている。 As shown in FIG. 5(b), both the upper and lower ends of the lock pin receiving portion 31a2 are bent at 45 degrees each in a direction away from the vertical plate portion 31a, so that the lock pin 23b is received smoothly and reliably.

水平板部31b,31bには、それぞれ、図5(a)~(c)等に示すように鉛直板部31aから遠い側端部、つまり図上右側に錠受け金具補助体32を固定するビス33を通すビス通し孔が形成されており、合計4本のビス33で錠受け金具補助体32が固定される。 As shown in Figures 5(a) to (c), the horizontal plate portions 31b, 31b each have a screw hole formed on the side end farthest from the vertical plate portion 31a, i.e., on the right side of the figure, through which the screw 33 for fixing the lock receiving metal fitting auxiliary body 32 passes, and the lock receiving metal fitting auxiliary body 32 is fixed with a total of four screws 33.

(錠受け金具補助体32)
錠受け金具補助体32は、図5(a)~(c)および図6(a),(b)に示すように、錠受け金具本体31の水平板部31b,31bに4本のビス33で鉛直板部31aと対向するように固定される補助体鉛直板部32aと、補助体鉛直板部32aの中央からロックピン受け部31a2に対向するようにほぼ90度曲がった後、さらに90度曲がってロックピン受け部31a2に向かって室内側に延び、負圧時に、ロック金具23の突出係止片23cが当接する第2受け部としての突出係止片当接部32bが設けられている。
(Lock receiving metal fitting auxiliary body 32)
As shown in Figures 5(a) to (c) and Figures 6(a) and (b), the lock receiving hardware auxiliary 32 comprises an auxiliary body vertical plate portion 32a which is fixed to the horizontal plate portions 31b, 31b of the lock receiving hardware main body 31 with four screws 33 so as to face the vertical plate portion 31a, and a protruding locking piece abutment portion 32b which bends approximately 90 degrees from the center of the auxiliary body vertical plate portion 32a to face the lock pin receiving portion 31a2 and then bends another 90 degrees to extend toward the inside of the room toward the lock pin receiving portion 31a2, and which serves as a second receiving portion with which the protruding locking piece 23c of the locking hardware 23 abuts when negative pressure is applied.

(室外側操作ハンドル4)
室外側操作ハンドル4は、障子12が開口枠11に閉められ、ロック金具23のロックピン23bが錠受け金具本体31のロックピン受け部31a2に係止している施錠状態(ロック状態)の場合でも、後述するように室外側からの操作によって障子12を室外側から開けるためのハンドルで、図7(a)~(c)に示すように構成されている。
(Outside operating handle 4)
The outside operating handle 4 is a handle for opening the shoji screen 12 from the outside of the room by operating it from the outside, as described below, even when the shoji screen 12 is closed against the opening frame 11 and the lock pin 23b of the locking fitting 23 is engaged with the lock pin receiving portion 31a2 of the lock receiving fitting main body 31 in a locked state (locked state), and is configured as shown in Figures 7(a) to (c).

つまり、室外側操作ハンドル4は、一枚の金属板等から構成され、図7(a)~(c)に示すように、スライド用係合部4aと、凸部4bとを有し、ネジやリベット等によって縦枠11dの上下方向に延びるスライド溝11d1(図7(a)参照。)に沿って上下方向にスライドする連動プレート26に連結されており、縦枠11dの見込み面に固定されるT字形状の室外側操作ハンドル支持金具11d2に上下方向スライド可能に設けられている。 In other words, the outdoor operating handle 4 is made of a single metal plate or the like, and as shown in Figures 7(a) to (c), has a slide engagement portion 4a and a protrusion 4b, and is connected to an interlocking plate 26 that slides vertically along a slide groove 11d1 (see Figure 7(a)) that extends vertically of the vertical frame 11d by screws, rivets, etc., and is mounted so as to be vertically slidable on a T-shaped outdoor operating handle support bracket 11d2 that is fixed to the visible surface of the vertical frame 11d.

室外側操作ハンドル支持金具11d2には、図7(b)に示すように室外側操作ハンドル4のスライド用係合部4aが係合して上下方向のスライドを案内する長穴形状のガイド孔11d21と、凸部4bが嵌るロック孔11d22とが設けられている。 As shown in FIG. 7(b), the outdoor operating handle support bracket 11d2 is provided with an elongated guide hole 11d21 that engages with the sliding engagement portion 4a of the outdoor operating handle 4 to guide the sliding in the up and down direction, and a lock hole 11d22 into which the protrusion 4b fits.

そのため、ユーザが室外側操作ハンドル4を上下方向にスライドさせる場合は、室外側操作ハンドル4を縦枠11d側に向かって押して、室外側操作ハンドル4を弾性的に曲げ、室外側操作ハンドル支持金具11d2のロック孔11d22に嵌っていた室外側操作ハンドル4の凸部4bが外れるので、室外側操作ハンドル4を上下方向にスライドすることができる。 Therefore, when the user slides the outdoor operation handle 4 up and down, the outdoor operation handle 4 is pushed toward the vertical frame 11d, causing the outdoor operation handle 4 to bend elastically, and the protrusion 4b of the outdoor operation handle 4 that was fitted into the lock hole 11d22 of the outdoor operation handle support bracket 11d2 is released, allowing the outdoor operation handle 4 to slide up and down.

尚、図7(b)に示す状態は、室外側操作ハンドル支持金具11d2のロック孔11d22に室外側操作ハンドル4の凸部4bが嵌っている状態で室外側操作ハンドル4が下げられている状態、すなわち連動プレート26を介して室外側操作ハンドル4に連結された錠受け金具3が所定の位置にあり、後述する図8(a)および図9(a)に示すようにロック金具23のロックピン23bが錠受け金具本体31のロックピン受け部31a2に係止しているロック状態である。 The state shown in Figure 7(b) is a state in which the protrusion 4b of the outdoor operating handle 4 is fitted into the lock hole 11d22 of the outdoor operating handle support bracket 11d2 and the outdoor operating handle 4 is lowered, i.e., the lock receiving bracket 3 connected to the outdoor operating handle 4 via the interlocking plate 26 is in a predetermined position, and the lock pin 23b of the locking bracket 23 is engaged with the lock pin receiving portion 31a2 of the lock receiving bracket main body 31, as shown in Figures 8(a) and 9(a) described below.

これに対し、ユーザが室外側操作ハンドル支持金具11d2のロック孔11d22に嵌っていた凸部4bを外し、室外側操作ハンドル4を上方向にスライドすることによって連動プレート26を介し錠受け金具3を上げると、後述する図9(b)に示すようにロック金具23に対し錠受け金具3が上昇し、ロック金具23のロックピン23bが錠受け金具本体31のロックピン受け部31a2から外れた解錠(ロック解除)状態となる。 In response to this, when the user removes the protrusion 4b that was fitted into the lock hole 11d22 of the outdoor operating handle support bracket 11d2 and slides the outdoor operating handle 4 upward to raise the lock receiving bracket 3 via the interlocking plate 26, the lock receiving bracket 3 rises relative to the locking bracket 23 as shown in FIG. 9(b) described below, and the lock pin 23b of the locking bracket 23 comes out of the lock pin receiving portion 31a2 of the locking bracket main body 31, entering an unlocked (unlocked) state.

(連動プレート26)
連動プレート26は、図2や図3、図7(a)等に示すように縦枠11dのスライド溝11d1内にスライド可能に設けられ、上端部においては図7(a),(b)に示すように室外側操作ハンドル4と連結される一方、下端部は少なくとも錠受け金具3まで延びており、錠受け金具3の錠受け金具本体31の傾斜長孔31a1,31a1(図5(b)参照。)にビス34(図3参照。)等で固定され、室外側操作ハンドル4の上下動に錠受け金具3も連動させ、室外側から施解錠機構2によるロック状態を解除させる部材である。
(Interlocking plate 26)
The interlocking plate 26 is slidably arranged within the slide groove 11d1 of the vertical frame 11d as shown in Figures 2, 3, 7(a), etc., and its upper end is connected to the exterior operating handle 4 as shown in Figures 7(a) and (b), while its lower end extends at least to the lock receiving fitting 3 and is fixed to the inclined long holes 31a1, 31a1 (see Figure 5(b)) of the lock receiving fitting main body 31 of the lock receiving fitting 3 with screws 34 (see Figure 3) or the like, so as to interlock the lock receiving fitting 3 with the up and down movement of the exterior operating handle 4, and release the locked state set by the locking/unlocking mechanism 2 from the outside of the room.

<実施形態1(戸先側)の負圧受け部材の動作等>
次に以上のように構成された実施形態1(戸先側)の負圧受け部材を構成する障子12の戸先側の縦框12dに設けた施解錠機構2のロック金具23と、開口枠11の戸先側の縦枠11dに設けた錠受け金具3の施錠状態(ロック状態)および解錠状態と、障子12を閉めて負圧を受けた際の動作について、図面を参照して説明する。
<Operation of the negative pressure receiving member of embodiment 1 (door end side)>
Next, with reference to the drawings, we will explain the locked and unlocked states of the locking hardware 23 of the locking/unlocking mechanism 2 provided on the vertical frame 12d on the door-end side of the shoji screen 12 which constitutes the negative pressure receiving member of embodiment 1 (door end side) configured as described above, and the lock receiving hardware 3 provided on the vertical frame 11d on the door-end side of the opening frame 11, as well as the operation when the shoji screen 12 is closed and receives negative pressure.

(施解錠機構2の締りハンドル21の操作による解錠状態)
図8(a)は、障子12の戸先側の縦框12dに設けた施解錠機構2のロック金具23の第1係止部としてのロックピン23bと、開口枠11の戸先側の縦枠11dに設けた錠受け金具3の第1受け部であるロックピン受け部31a2とが係止した障子12の施錠状態(ロック状態)を示している。この施錠状態(ロック状態)で、負圧によって障子12が室外側に変位すると、ロック金具23の第2係止部である突出係止片23cも錠受け金具3の第2受け部である突出係止片当接部32bに係止(当接)可能である。
(Unlocked state by operation of the locking handle 21 of the locking/unlocking mechanism 2)
8(a) shows the locked state of the shoji screen 12 in which the lock pin 23b serving as the first engagement portion of the locking metal fitting 23 of the locking/unlocking mechanism 2 provided on the vertical frame 12d on the door end side of the shoji screen 12 is engaged with the lock pin receiving portion 31a2 serving as the first receiving portion of the lock receiving metal fitting 3 provided on the vertical frame 11d on the door end side of the opening frame 11. In this locked state, when the shoji screen 12 is displaced to the outside of the room due to negative pressure, the protruding locking piece 23c serving as the second engagement portion of the locking metal fitting 23 can also be engaged (abut) with the protruding locking piece abutment portion 32b serving as the second receiving portion of the lock receiving metal fitting 3.

そして、図8(a)に示す障子12の施錠状態(ロック状態)からユーザが室内側の施解錠機構2の締りハンドル21を操作すると、図8(b)に示すようにロック金具23のロックピン23bが下方へスライドして、ロック金具23の第1係止部であるロックピン23bと錠受け金具3の第1受け部であるロックピン受け部31a2とが非係止状態になると共に、ロック金具23の第2係止部である突出係止片23cと錠受け金具3の第2受け部である突出係止片当接部32bとが非係止状態になって障子12の施錠状態(ロック状態)が解除され、開口枠11に対し障子12を自由に開閉できることになる。 When the user operates the locking handle 21 of the locking/unlocking mechanism 2 on the inside of the room from the locked state of the screen 12 shown in FIG. 8(a), the lock pin 23b of the locking fitting 23 slides downward as shown in FIG. 8(b), and the lock pin 23b, which is the first locking part of the locking fitting 23, and the lock pin receiving part 31a2, which is the first receiving part of the lock receiving fitting 3, enter an unlocked state, and the protruding locking piece 23c, which is the second locking part of the locking fitting 23, and the protruding locking piece abutment part 32b, which is the second receiving part of the lock receiving fitting 3, enter an unlocked state, and the locked state of the screen 12 is released, and the screen 12 can be freely opened and closed relative to the opening frame 11.

(室外側操作ハンドル4の操作による解錠状態)
図9(a)は、図8(a)と同様に施解錠機構2のロック金具23の第1係止部としてのロックピン23bと、錠受け金具3の第1受け部であるロックピン受け部31a2とが係止した障子12の施錠状態(ロック状態)を示しており、ロック金具23の第2係止部である突出係止片23cも錠受け金具3の第2受け部である突出係止片当接部32bに係止状態にある。
(Unlocked state by operating the exterior operating handle 4)
Figure 9 (a), like Figure 8 (a), shows the locked state (locked state) of the screen 12 in which the lock pin 23b, which is the first engagement portion of the lock fitting 23 of the locking/unlocking mechanism 2, is engaged with the lock pin receiving portion 31a2, which is the first receiving portion of the lock receiving fitting 3, and the protruding locking piece 23c, which is the second engagement portion of the lock fitting 23, is also in an engaged state with the protruding locking piece abutment portion 32b, which is the second receiving portion of the lock receiving fitting 3.

そして、図9(a)に示す障子12の施錠状態(ロック状態)からユーザが室外側の室外側操作ハンドル4(図1や図7参照。)を上方へスライドさせると、室外側操作ハンドル4に連動プレート26を介し連結された錠受け金具3も連動して、図9(b)に示すようにロック金具23に対し錠受け金具3が上昇し、錠受け金具3の第1受け部であるロックピン受け部31a2がロック金具23の第1係止部であるロックピン23bと非係止状態になると共に、錠受け金具3の第2受け部である突出係止片当接部32bがロック金具23の第2係止部である突出係止片23cと非係止状態になって、図8(b)に示す施解錠機構2の締りハンドル21を回転操作した場合と同様に開口枠11に対し障子12を自由に開閉できることになる。 When the user slides the exterior operating handle 4 (see Figs. 1 and 7) upward from the locked state of the screen 12 shown in Fig. 9(a), the lock receiving metal fitting 3 connected to the exterior operating handle 4 via the interlocking plate 26 also moves in conjunction with the lock receiving metal fitting 3, and the lock receiving metal fitting 3 rises relative to the locking metal fitting 23 as shown in Fig. 9(b). The lock pin receiving portion 31a2, which is the first receiving portion of the lock receiving metal fitting 3, is disengaged from the lock pin 23b, which is the first locking portion of the locking metal fitting 23, and the protruding locking piece abutment portion 32b, which is the second receiving portion of the lock receiving metal fitting 3, is disengaged from the protruding locking piece 23c, which is the second locking portion of the locking metal fitting 23. As a result, the screen 12 can be freely opened and closed relative to the opening frame 11, just as when the tightening handle 21 of the locking/unlocking mechanism 2 shown in Fig. 8(b) is rotated.

(障子12を閉め施解錠機構2でロックした際に負圧を受けた場合)
次に障子12を閉めて図8(a)および図9(a)に示すように施解錠機構2と錠受け金具3で施錠(ロック)した後、負圧を受けた際の実施形態1(戸先側)の負圧受け部材を構成するロック金具23と錠受け金具3との係止状態について、図10および図11を参照して説明する。尚、図10および図11では、ロック金具23と錠受け金具3との係止に関係しないガラス13等の構成は、図示を省略する。
(When negative pressure is applied when the door 12 is closed and locked by the locking/unlocking mechanism 2)
Next, after the sliding screen 12 is closed and locked with the locking/unlocking mechanism 2 and the lock receiving metal fitting 3 as shown in Figures 8(a) and 9(a), the engagement state between the locking metal fitting 23 and the lock receiving metal fitting 3 constituting the negative pressure receiving member of embodiment 1 (door end side) when negative pressure is applied will be described with reference to Figures 10 and 11. Note that in Figures 10 and 11, the configuration of the glass 13 and the like that is not related to the engagement between the locking metal fitting 23 and the lock receiving metal fitting 3 is omitted.

図10(a)は、障子12の施錠状態(ロック状態)における戸先側の縦枠11dおよび縦框12dの拡大断面図であり、図2および図3と同じ状態である。 Figure 10 (a) is an enlarged cross-sectional view of the vertical frame 11d and vertical stile 12d on the door end side when the shoji screen 12 is in a locked state (locked state), which is the same state as Figures 2 and 3.

図10(a)に示す障子12の施錠状態(ロック状態)において、台風等によって室外側が負圧になると、その負圧によって障子12の室外側が凸となるように湾曲し、例えば、障子12の縦框12d自体や縦框12dに設けた施解錠機構2等も室外側が凸となるように湾曲した障子12のガラス13に引っ張られ、図10(b)に示すように反時計回りに回転して傾斜する。 When the shoji screen 12 is in the locked state shown in Figure 10(a), if the outside of the room becomes negative pressure due to a typhoon or other event, the negative pressure causes the outside of the shoji screen 12 to curve so that it becomes convex. For example, the vertical frame 12d of the shoji screen 12 itself and the locking/unlocking mechanism 2 installed on the vertical frame 12d are also pulled by the glass 13 of the shoji screen 12, which is curved so that the outside of the room becomes convex, and rotate counterclockwise and tilt as shown in Figure 10(b).

すると、図10(b)に示すようにロック金具23の第1係止部としてのロックピン23bや第2係止部としての突出係止片23cも傾斜し、第1係止部としてのロックピン23bは開口枠11の戸先側の縦枠11dに設けた錠受け金具3の第1受け部であるロックピン受け部31a2に当接したまま、ロックピン受け部31a2にて負圧を受ける。 As a result, as shown in FIG. 10(b), the lock pin 23b as the first locking part of the locking fitting 23 and the protruding locking piece 23c as the second locking part also tilt, and the lock pin 23b as the first locking part receives negative pressure at the lock pin receiving part 31a2 while remaining in contact with the lock pin receiving part 31a2, which is the first receiving part of the lock receiving fitting 3 provided on the vertical frame 11d on the door end side of the opening frame 11.

また、図10(b)に示すようにロック金具23の第2係止部である突出係止片23cも開口枠11の戸先側の縦枠11dに設けた錠受け金具3の水平板部31b(下側)に当接し、負圧を受ける。つまり、ロック金具23の突出係止片23cの開口枠側の面が錠受け金具3に当接して、負圧を受けることができる。 As shown in FIG. 10(b), the protruding engagement piece 23c, which is the second engagement part of the locking metal fitting 23, also comes into contact with the horizontal plate part 31b (lower side) of the lock receiving metal fitting 3 provided on the vertical frame 11d on the door end side of the opening frame 11, and is subjected to negative pressure. In other words, the surface on the opening frame side of the protruding engagement piece 23c of the locking metal fitting 23 comes into contact with the lock receiving metal fitting 3, and is subjected to negative pressure.

図10(b)に示す状態からさらに負圧が大きくなると、例えば、図11(a)に示すようにロック金具23の第1係止部としてのロックピン23bや第2係止部としての突出係止片23cの傾斜角度が図10(b)に示す場合よりもさら大きくなると共に、障子12の戸先側の縦框12dが開口枠11の戸先側の縦枠11dから離れる。 When the negative pressure increases from the state shown in FIG. 10(b), for example, as shown in FIG. 11(a), the inclination angle of the lock pin 23b as the first locking part of the locking fitting 23 and the protruding locking piece 23c as the second locking part becomes larger than that shown in FIG. 10(b), and the vertical frame 12d on the door end side of the shoji screen 12 moves away from the vertical frame 11d on the door end side of the opening frame 11.

そのため、例えば、図11(a)に示すように第1係止部としてのロックピン23bは、錠受け金具3の第1受け部であるロックピン受け部31a2に当接してロックピン受け部31a2にて負圧を受けているものの、図10(a),(b)に示す場合よりもロックピン受け部31a2との係止寸法が小さくなっている。 For example, as shown in FIG. 11(a), the lock pin 23b as the first locking part abuts against the lock pin receiving part 31a2, which is the first receiving part of the lock receiving metal fitting 3, and is subjected to negative pressure at the lock pin receiving part 31a2, but the locking dimension with the lock pin receiving part 31a2 is smaller than in the case shown in FIGS. 10(a) and (b).

また、図11(a)に示す状態では、ロック金具23の第2係止部である突出係止片23cは、図10(b)に示す場合よりも傾斜し、かつ、縦枠11dから離れるため、錠受け金具3の水平板部31bから離れた状態になっている。 In addition, in the state shown in FIG. 11(a), the protruding locking piece 23c, which is the second locking portion of the locking metal fitting 23, is tilted more than in the state shown in FIG. 10(b) and is away from the vertical frame 11d, and is therefore away from the horizontal plate portion 31b of the lock receiving metal fitting 3.

図11(a)に示す状態からさらに負圧が大きくなると、例えば、図11(b)に示すようにロック金具23の第1係止部としてのロックピン23bや第2係止部としての突出係止片23cの傾斜角度が図10(b)に示す場合よりもさらに傾斜すると共に、障子12の戸先側の縦框12dが開口枠11の戸先側の縦枠11dから離れる。 When the negative pressure increases from the state shown in FIG. 11(a), for example, as shown in FIG. 11(b), the inclination angle of the lock pin 23b as the first locking part of the locking fitting 23 and the protruding locking piece 23c as the second locking part become more inclined than in the case shown in FIG. 10(b), and the vertical frame 12d on the door end side of the shoji screen 12 moves away from the vertical frame 11d on the door end side of the opening frame 11.

そのため、図11(b)に示す状態では、図11(a)に示す場合よりも第1係止部としてのロックピン23bが錠受け金具3の第1受け部であるロックピン受け部31a2から遠ざかるものの、図11(a)に示す場合と同様にロックピン受け部31a2との係止状態を維持している。 Therefore, in the state shown in FIG. 11(b), the lock pin 23b as the first locking part is farther away from the lock pin receiving part 31a2, which is the first receiving part of the lock receiving metal fitting 3, than in the state shown in FIG. 11(a), but the lock pin 23b maintains the locking state with the lock pin receiving part 31a2, just as in the state shown in FIG. 11(a).

そして、図11(b)に示す状態では、ロック金具23の第2係止部である突出係止片23cは、図11(a)に示す場合よりも傾斜し、かつ、縦枠11dから遠ざかるため、錠受け金具3の第2受け部である突出係止片当接部32bに当接し、突出係止片当接部32bにて負圧を受ける。つまり、ロック金具23の突出係止片23cの障子側の面が錠受け金具3に当接して、負圧を受けることができる。よって、ロック金具23の突出係止片23cは、その両側面の何れかが、障子12が受ける負圧の大きさに応じて錠受け金具3に当接して、負圧を受けることができる。 In the state shown in FIG. 11(b), the protruding locking piece 23c, which is the second locking portion of the locking fitting 23, is tilted more than in the state shown in FIG. 11(a) and moves away from the vertical frame 11d, so that it abuts against the protruding locking piece abutment portion 32b, which is the second receiving portion of the lock receiving fitting 3, and receives negative pressure at the protruding locking piece abutment portion 32b. In other words, the shoji side surface of the protruding locking piece 23c of the locking fitting 23 abuts against the lock receiving fitting 3 and can receive negative pressure. Therefore, either of the two side surfaces of the protruding locking piece 23c of the locking fitting 23 abuts against the lock receiving fitting 3 depending on the magnitude of the negative pressure received by the shoji 12, and can receive negative pressure.

<実施形態1(戸先側)の負圧受け部材のまとめ>
従って、本発明に係る実施形態1(戸先側)の負圧受け部材は、障子12側の係止部材である施解錠機構2を構成するロック金具23に、開口枠に向かって突出する第1係止部としてのロックピン23bと、そのロックピン23bに対し室内側から室外側に向う見込み方向に所定間隔を空けて開口枠に向かって突出する第2係止部としての突出係止片23cとを設ける一方、開口枠11側の受け部材である錠受け金具3には、ロックピン23bが係止可能な第1受け部としてのロックピン受け部31a2と、第2係止部である突出係止片23cが係止可能な第2受け部としての突出係止片当接部32bを設けている。
<Summary of negative pressure receiving member of embodiment 1 (door end side)>
Therefore, the negative pressure receiving member of embodiment 1 (door end side) of the present invention is provided with a locking fitting 23 that constitutes the locking/unlocking mechanism 2, which is the locking member on the shoji 12 side, and is provided with a locking pin 23b as a first locking portion that protrudes toward the opening frame, and a protruding locking piece 23c as a second locking portion that protrudes toward the opening frame at a predetermined interval from the locking pin 23b in the projected direction from the inside to the outside of the room, while the lock receiving fitting 3, which is the receiving member on the opening frame 11 side, is provided with a lock pin receiving portion 31a2 as a first receiving portion with which the locking pin 23b can be engaged, and a protruding locking piece abutment portion 32b as a second receiving portion with which the protruding locking piece 23c, which is the second locking portion, can be engaged.

そのため、本発明に係る実施形態1(戸先側)の負圧受け部材によれば、障子12が負圧を受けた際、ロックピン23bとロックピン受け部31a2との係止と、突出係止片23cと突出係止片当接部32bとの係止の2箇所の係止で障子12にかかる負圧を確実に受けるので、大きい負圧にも確実に耐えることができる。 Therefore, according to the negative pressure receiving member of embodiment 1 (door end side) of the present invention, when the shoji screen 12 receives negative pressure, the negative pressure acting on the shoji screen 12 is reliably received by two engagements: the engagement between the lock pin 23b and the lock pin receiving portion 31a2, and the engagement between the protruding locking piece 23c and the protruding locking piece abutment portion 32b, so that the shoji screen 12 can reliably withstand even large negative pressures.

尚、上記の実施形態1(戸先側)の説明では、開口枠11の戸先側の縦枠11dに上下方向にスライドする連動プレート26を設け、その連動プレート26を介し室外側操作ハンドル4と錠受け金具3とを連結して、室外側操作ハンドル4の上下動により錠受け金具3も上下動して室外側からも施解錠機構2による施錠状態(ロック状態)を解除できるように説明したが、本発明では連動プレート26および室外側操作ハンドル4は必須のものでないため、連動プレート26や室外側操作ハンドル4を省略する場合には、錠受け金具3は錠受け金具本体31の傾斜長孔31a1,31a1にビスやネジを挿入して開口枠11の戸先側の縦枠11dに固定されることになる。 In the above description of embodiment 1 (door end side), an interlocking plate 26 that slides up and down is provided on the vertical frame 11d on the door end side of the opening frame 11, and the exterior operating handle 4 and the lock receiving hardware 3 are connected via the interlocking plate 26, so that the lock receiving hardware 3 moves up and down as the exterior operating handle 4 moves up and down, allowing the locking state (locked state) by the locking/unlocking mechanism 2 to be released from the exterior side as well. However, since the interlocking plate 26 and the exterior operating handle 4 are not essential to this invention, if the interlocking plate 26 and the exterior operating handle 4 are omitted, the lock receiving hardware 3 will be fixed to the vertical frame 11d on the door end side of the opening frame 11 by inserting screws or bolts into the inclined long holes 31a1, 31a1 of the lock receiving hardware main body 31.

<実施形態2(吊元側)の負圧受け部材>
次に、本発明に係る実施形態2(吊元側)の縦すべり出し窓1の負圧受け部材について説明する。実施形態2(吊元側)の縦すべり出し窓1の負圧受け部材は、図1や図12等に示すように、障子12の吊元側(戸尻側)の縦框12cに設けた係止部材としての障子吊元側係止金具5と、開口枠11の吊元側(戸尻側)の縦枠11cに設けた受け部材としての縦枠吊元側受け金具6で構成される。尚、障子吊元側係止金具5と縦枠吊元側受け金具6とは、同じ金具であるため、図13では両者を代表して障子吊元側係止金具5を示している。
<Negative pressure receiving member of embodiment 2 (hanging side)>
Next, the negative pressure receiving member of the vertical sliding window 1 of the second embodiment (hanging side) of the present invention will be described. As shown in Figures 1 and 12, the negative pressure receiving member of the vertical sliding window 1 of the second embodiment (hanging side) is composed of a door hanging side locking metal fitting 5 as a locking member provided on the vertical frame 12c on the hanging side (door end side) of the door 12, and a vertical frame hanging side receiving metal fitting 6 as a receiving member provided on the vertical frame 11c on the hanging side (door end side) of the opening frame 11. Note that the door hanging side locking metal fitting 5 and the vertical frame hanging side receiving metal fitting 6 are the same metal fittings, so in Figure 13, the door hanging side locking metal fitting 5 is shown as a representative of both.

(障子吊元側係止金具5)
障子吊元側係止金具5は、図13(a)~(c)に示すように、平面視コ字形状で、障子12の縦框12cに固定される係止側固定板部5aと、その係止側固定板部5aの見込み方向における室内側端部と室外側端部の両側からそれぞれ対向する開口枠11の縦枠11cに向って延びる一対の第1係止部としての係止用側板部5bおよび第2係止部としての係止用側板部5cとを備えて構成される。
(Latching bracket 5 on the hanging side of the shoji screen)
As shown in Figures 13 (a) to (c), the shoji hanging side locking bracket 5 is U-shaped when viewed from above and is composed of a locking side fixed plate portion 5a that is fixed to the vertical frame 12c of the shoji 12, and a pair of locking side plate portions 5b and 5c as first and second locking portions extending from both the interior and exterior ends of the locking side fixed plate portion 5a in the expected direction toward the opposing vertical frames 11c of the opening frame 11.

係止側固定板部5aには、図13(c)等に示すように障子12の縦框12cにビス51等で固定するためのビス孔5a1が2箇所形成されている。ビス孔5a1は、固定位置を調整できるように長孔形状に形成されている。 The locking side fixing plate portion 5a has two screw holes 5a1 for fixing to the vertical frame 12c of the shoji screen 12 with screws 51 or the like, as shown in FIG. 13(c) etc. The screw holes 5a1 are formed in an elongated hole shape so that the fixing position can be adjusted.

一対の係止用側板部5b,5cは、図12や図13(a)等に示すようにその係止側固定板部5aの見込み方向における両側からそれぞれ対向する開口枠11の吊元側に向って延びつつ室外側に向って傾斜し、それぞれ、係止側固定板部5aに対し、80度と100度の角度をなしている。 As shown in Figures 12 and 13(a), the pair of locking side plate parts 5b, 5c extend from both sides of the locking side fixing plate part 5a in the forward direction toward the hanging side of the opening frame 11 that they face, while inclining toward the outside of the room, and form angles of 80 degrees and 100 degrees, respectively, with respect to the locking side fixing plate part 5a.

(縦枠吊元側受け金具6)
縦枠吊元側受け金具6は、図13(a)~(c)に示す障子吊元側係止金具5と同一形状の部材であるが、図12に示すように開口側が障子12の縦框12cの方向を向くよう開口枠11の吊元側の縦枠11cに固定される金具で、開口枠11の吊元側の縦枠11cに固定される受け側固定板部6aと、その受け側固定板部6aの見込み方向における室内側端部と室外側端部の両側からそれぞれ対向する障子12の吊元側の縦框12cに向って延びる一対の第1受け部としての受け用側板部6bおよび第2受け部としての受け用側板部6cとを備えて構成される。
(Vertical frame hanging side support bracket 6)
The vertical frame hanging side support bracket 6 is a component of the same shape as the shoji hanging side locking bracket 5 shown in Figures 13 (a) to (c), but is a bracket that is fixed to the vertical frame 11c on the hanging side of the opening frame 11 so that the opening side faces the vertical frame 12c of the shoji 12 as shown in Figure 12, and is composed of a receiving side fixed plate portion 6a fixed to the vertical frame 11c on the hanging side of the opening frame 11, and a pair of receiving side plate portions 6b and 6c as first and second receiving portions that extend from both the indoor side end and the outdoor side end of the receiving side fixed plate portion 6a in the expected direction toward the opposing vertical frame 12c on the hanging side of the shoji 12.

受け側固定板部6aには、ビス孔が2箇所形成されており、その2箇所のビス孔にビス61で固定される。 The receiving side fixing plate portion 6a has two screw holes, and is fixed into the two screw holes with screws 61.

一対の受け用側板部6b,6cは、図12や図13(a)等に示すようにその受け側固定板部6aの見込み方向における両側からそれぞれ対向する障子12の縦框12cに向って延びつつ室内側に向って傾斜し、それぞれ、受け側固定板部6aに対し、100度と80度の角度をなして、図12等に示すように障子吊元側係止金具5の一対の係止用側板部5b,5cに重なるように縦枠吊元側受け金具6が係止(当接)可能に取り付けられる。 As shown in Figures 12 and 13(a), the pair of receiving side plates 6b, 6c extend from both sides of the receiving fixed plate 6a in the forward direction toward the vertical frame 12c of the shoji screen 12, while inclining toward the room interior, and are attached so that the vertical frame hanging side receiving bracket 6 can be engaged (abut) with the pair of engaging side plates 5b, 5c of the shoji hanging side retaining bracket 5 at angles of 100 degrees and 80 degrees, respectively, relative to the receiving fixed plate 6a, as shown in Figure 12, etc.

<実施形態2(吊元側)の負圧受け部材の動作等>
次に障子12を閉めて施解錠機構2で施錠(ロック)した後、負圧を受けた際の実施形態2(吊元側)の負圧受け部材を構成する障子吊元側係止金具5と縦枠吊元側受け金具6の動作について、図14および図15を参照して説明する。尚、図14および図15では、主に係止部材としての障子吊元側係止金具5と受け部材としての縦枠吊元側受け金具6との係止状態を示すため、障子吊元側係止金具5と縦枠吊元側受け金具6との係止に関係しないガラス13等の構成は、図示を省略して説明する。
<Operation of the negative pressure receiving member of the second embodiment (hanging side)>
Next, the operation of the door hanging side locking fitting 5 and the vertical frame hanging side receiving fitting 6, which constitute the negative pressure receiving member of embodiment 2 (hanging side) when negative pressure is applied after the door 12 is closed and locked by the locking/unlocking mechanism 2, will be described with reference to Figures 14 and 15. Note that Figures 14 and 15 mainly show the locking state between the door hanging side locking fitting 5 as the locking member and the vertical frame hanging side receiving fitting 6 as the receiving member, so the configuration of the glass 13 and the like that is not related to the locking between the door hanging side locking fitting 5 and the vertical frame hanging side receiving fitting 6 will be described without showing them.

図14(a)は、障子12を閉めて施解錠機構2でロックした際の吊元側の状態を示す拡大断面図であり、図12と同じ状態である。このような障子12を閉めて施解錠機構2の施錠状態(ロック状態)において台風等によって室外側が負圧になると、障子12の室外側が凸となるように湾曲し、室外側が凸となるように湾曲した障子12のガラス13に引っ張られて、例えば、図14(b)に示すように障子12の縦框12c自体や縦框12cに設けた障子吊元側係止金具5等も図14(b)上で時計回りに回転して傾斜する。 Figure 14(a) is an enlarged cross-sectional view showing the state of the hanging side when the door 12 is closed and locked by the locking mechanism 2, and is the same state as in Figure 12. When the door 12 is closed and the locking mechanism 2 is in the locked state (locked state), if a typhoon or other event causes negative pressure on the outside of the room, the outside of the door 12 will bend convexly, and will be pulled by the glass 13 of the door 12, which is curved so that the outside of the room is convex, and as shown in Figure 14(b), for example, the vertical frame 12c of the door 12 itself and the door hanging side locking fittings 5 attached to the vertical frame 12c will rotate and tilt clockwise on Figure 14(b).

その際、図14(b)に示すように、障子12側の障子吊元側係止金具5が傾斜したとしても、障子吊元側係止金具5の第1係止部および第2係止部である一対の係止用側板部5b,5cが、それぞれ、縦枠11cに取付けた縦枠吊元側受け金具6の第1受け部および第2受け部としての一対の受け用側板部6b,6cが見込み方向に重なっているため、障子12が室外側に引っ張られたとしても2箇所で負圧を受けることができる。 In this case, as shown in FIG. 14(b), even if the shoji hanging side locking bracket 5 on the shoji 12 side is tilted, the pair of locking side plate portions 5b, 5c which are the first and second locking portions of the shoji hanging side locking bracket 5 overlap in the forward direction with the pair of receiving side plate portions 6b, 6c which are the first and second receiving portions of the vertical frame hanging side receiving bracket 6 attached to the vertical frame 11c, so that the shoji 12 can receive negative pressure at two points even if it is pulled to the outside of the room.

そしてさらに負圧によって障子12の室外側が凸となるように湾曲すると、図14(b)に示す状態から図15(a)に示す状態に移行して、障子12の縦框12c自体や縦框12cに設けた障子吊元側係止金具5等も図15(a)上でさらに時計回りに回転してさらに傾斜する。 When the negative pressure further bends the screen 12 so that the outside of the room becomes convex, it transitions from the state shown in FIG. 14(b) to the state shown in FIG. 15(a), and the vertical frame 12c of the screen 12 itself and the screen hanging side locking fittings 5 attached to the vertical frame 12c also rotate further clockwise on FIG. 15(a) and become even more tilted.

図15(a)の場合、図14(b)の場合よりも障子12側の障子吊元側係止金具5が傾斜し、かつ、縦枠11c側の縦枠吊元側受け金具6から遠ざかっているが、障子吊元側係止金具5の第1係止部である係止用側板部5bが、縦枠11cに取付けた縦枠吊元側受け金具6の第1受け部としての受け用側板部6bに当接し、受け用側板部6bで負圧を受けることができる。 In the case of Figure 15(a), the shoji hanging side locking bracket 5 on the shoji 12 side is tilted more than in the case of Figure 14(b) and is farther away from the vertical frame hanging side support bracket 6 on the vertical frame 11c side, but the locking side plate portion 5b, which is the first locking part of the shoji hanging side locking bracket 5, abuts against the support side plate portion 6b, which is the first support part of the vertical frame hanging side support bracket 6 attached to the vertical frame 11c, and the support side plate portion 6b can receive negative pressure.

そしてさらに負圧によって図15(a)に示す状態から図15(b)に示す状態に移行して、障子12の縦框12c自体や縦框12cに設けた障子吊元側係止金具5等も図15(b)上でさらに時計回りに回転してさらに傾斜し、かつ、縦枠11c側の縦枠吊元側受け金具6からさらに遠ざかっても、図15(b)に示すように障子吊元側係止金具5の第1係止部および第2係止部である一対の係止用側板部5b,5cと縦枠11cに取付けた縦枠吊元側受け金具6の第1受け部および第2受け部としての一対の受け用側板部6b,6cとが当接しているため、確実に2箇所で負圧を受けることができる。 Then, the negative pressure causes the screen 12 to move from the state shown in FIG. 15(a) to the state shown in FIG. 15(b), and the vertical frame 12c of the screen 12 and the screen hanging side locking bracket 5 attached to the vertical frame 12c rotate further clockwise on FIG. 15(b) and tilt further, and move further away from the vertical frame hanging side support bracket 6 on the vertical frame 11c side. However, as shown in FIG. 15(b), the pair of locking side plates 5b, 5c, which are the first and second locking parts of the screen hanging side locking bracket 5, are in contact with the pair of support side plates 6b, 6c, which are the first and second support parts of the vertical frame hanging side support bracket 6 attached to the vertical frame 11c, so the screen can reliably receive the negative pressure at two points.

<実施形態2(吊元側)の負圧受け部材のまとめ>
以上説明したように、本発明に係る実施形態2(吊元側)の負圧受け部材は、障子12側の障子吊元側係止金具5と開口枠11側の縦枠吊元側受け金具6とで構成し、障子吊元側係止金具5には第1係止部および第2係止部として一対の係止用側板部5b,5cを設ける一方、縦枠吊元側受け金具6には第1受け部および第2受け部として一対の受け用側板部6b,6cを設けている。
<Summary of negative pressure receiving member of embodiment 2 (hanging side)>
As described above, the negative pressure receiving member of embodiment 2 (hanging side) of the present invention is composed of a shoji hanging side locking bracket 5 on the shoji 12 side and a vertical frame hanging side support bracket 6 on the opening frame 11 side, and the shoji hanging side locking bracket 5 is provided with a pair of locking side plates 5b, 5c as the first locking portion and the second locking portion, while the vertical frame hanging side support bracket 6 is provided with a pair of support side plates 6b, 6c as the first support portion and the second support portion.

そのため、本発明に係る実施形態2(吊元側)の負圧受け部材によれば、障子12が負圧を受けた際、係止用側板部5bと受け用側板部6bとの係止と、係止用側板部5cと受け用側板部6cとの係止の2箇所の係止で障子12にかかる負圧を受けるので、大きい負圧にも確実に耐えることができる。 Therefore, with the negative pressure receiving member of embodiment 2 (hanging side) of the present invention, when the shoji screen 12 receives negative pressure, the negative pressure is received by two engagements: the engagement between the locking side plate portion 5b and the receiving side plate portion 6b, and the engagement between the locking side plate portion 5c and the receiving side plate portion 6c, so that the shoji screen 12 can reliably withstand large negative pressures.

また、本発明に係る実施形態2(吊元側)の負圧受け部材である障子吊元側係止金具5と縦枠吊元側受け金具6とでは、同じ物を使用しているので、部品点数を減らすことで管理コストを削減することができる。 In addition, the negative pressure receiving members in embodiment 2 (hanging side) of the present invention, the locking bracket 5 on the hanging side of the shoji screen and the receiving bracket 6 on the hanging side of the vertical frame, are the same, so the number of parts can be reduced, thereby reducing management costs.

また、本発明に係る実施形態2(吊元側)の負圧受け部材では、通常時における障子の開閉を妨げないように、障子吊元側係止金具5の一対の係止用側板部5b,5cは、それぞれ係止側固定板部5aの両側からそれぞれ対向する開口枠11の吊元側に向って延びつつ室外側に10度ずつ傾斜するように構成する一方、縦枠吊元側受け金具6の一対の受け用側板部6b,6cは、その受け側固定板部6aの両側からそれぞれ対向する障子12の吊元側に向って延びつつ室内側に10度ずつ傾斜させている。 In addition, in the negative pressure receiving member of embodiment 2 (hanging side) of the present invention, in order not to interfere with the opening and closing of the shoji screen under normal circumstances, the pair of locking side plate portions 5b, 5c of the shoji screen hanging side locking fitting 5 are configured to extend from both sides of the locking side fixed plate portion 5a toward the hanging side of the opposing opening frame 11 and incline 10 degrees toward the outside of the room, while the pair of receiving side plate portions 6b, 6c of the vertical frame hanging side receiving fitting 6 extend from both sides of the receiving side fixed plate portion 6a toward the hanging side of the opposing shoji screen 12 and incline 10 degrees toward the inside of the room.

そのため、負圧によって障子12が室外側に引っ張られ、障子12側の障子吊元側係止金具5が縦枠11c側の縦枠吊元側受け金具6から遠ざかろうとした場合、一対の係止用側板部5b,5cおよび一対の受け用側板部6b,6cが、障子吊元側係止金具5の第1係止部および第2係止部として一対の係止用側板部5b,5cと縦枠吊元側受け金具6の第1受け部および第2受け部として一対の受け用側板部6b,6cとが図15(b)に示すように確実に2箇所で係止するので、大きい負圧に確実に耐えることが可能となる。 Therefore, when the negative pressure pulls the shoji 12 to the outside of the room and the shoji hanging side locking bracket 5 on the shoji 12 side tries to move away from the vertical frame hanging side support bracket 6 on the vertical frame 11c side, the pair of locking side plates 5b, 5c and the pair of support side plates 6b, 6c reliably lock in two places as shown in Figure 15 (b) with the pair of locking side plates 5b, 5c as the first and second locking parts of the shoji hanging side locking bracket 5 and the pair of support side plates 6b, 6c as the first and second support parts of the vertical frame hanging side support bracket 6, making it possible to reliably withstand large negative pressure.

尚、一対の係止用側板部5b,5cおよび一対の受け用側板部6b,6cを見付け方向、すなわち障子12と平行に設けた場合は、係止用側板部5bと受け用側板部6bとの間、および係止用側板部5cと受け用側板部6cとの間にクリアランスを設ける必要があるため、確実に2箇所で係止させることは難しい。 In addition, if the pair of locking side plates 5b, 5c and the pair of receiving side plates 6b, 6c are arranged in the viewing direction, i.e., parallel to the screen 12, it is necessary to provide clearance between the locking side plate 5b and the receiving side plate 6b, and between the locking side plate 5c and the receiving side plate 6c, making it difficult to securely lock in two places.

尚、上記の説明では、図1等に示すように、本発明に係る実施形態1(戸先側)の負圧受け部材を構成するロック金具23と錠受け金具3とをそれぞれ縦すべり出し窓1の障子12の戸先側の縦框12dと開口枠11の戸先側の縦枠11dに設けると共に、本発明に係る実施形態2(吊元側)の負圧受け部材を構成する障子吊元側係止金具5と縦枠吊元側受け金具6とをそれぞれ縦すべり出し窓1の障子12の吊元側の縦框12cと開口枠11の吊元側の縦枠11cに設けて説明したが、本発明ではこれに限らず、縦すべり出し窓1の戸先側の縦框12dと縦枠11dにのみ本発明に係る実施形態1(戸先側)の負圧受け部材を構成するロック金具23と錠受け金具3とを設け、縦すべり出し窓1の吊元側の縦框12cと縦枠11cには従来の障子吊元側係止金具と縦枠吊元側受け金具とを設けても良いし、縦すべり出し窓1の吊元側の縦框12cと縦枠11cにのみ本発明に係る実施形態2(吊元側)の負圧受け部材を構成する障子吊元側係止金具5と縦枠吊元側受け金具6とを設け、縦すべり出し窓1の戸先側の縦框12dと縦枠11dには従来のロック金具と錠受け金具とをそれぞれ設けるようにしても勿論良い。 In the above explanation, as shown in FIG. 1 etc., the locking fitting 23 and the locking fitting 3 constituting the negative pressure receiving member of the first embodiment (door end side) of the present invention are respectively provided on the vertical frame 12d on the door end side of the shoji 12 of the vertical sliding window 1 and the vertical frame 11d on the door end side of the opening frame 11, while the shoji hanging side locking fitting 5 and the vertical frame hanging side receiving fitting 6 constituting the negative pressure receiving member of the second embodiment (hanging side) of the present invention are respectively provided on the vertical frame 12c on the hanging side of the shoji 12 of the vertical sliding window 1 and the vertical frame 11c on the hanging side of the opening frame 11.
