Description

【0001】
【発明の属する技術分野】
この発明は開口部の下側に敷設された下部レール上に、折り畳み式網戸の下部スライドレールを摺動自在に支持させた折り畳み式網戸の支持構造に関するものである。
【0002】
【従来の技術及び発明が解決しようとする課題】
折り畳み式網戸は戸先框の上端と下端に接続される上部スライドレールと下部スライドレールが開口部の上側と下側に、開口部に平行に敷設された上部レールと下部レールに沿って移動することにより開閉するため、戸先框が上部レールに直接、または特開平8-121054号のようにワイヤ等を通じ、間接的に上吊り式に支持される場合以外、戸先框は下部スライドレールが下部レール上を摺動することにより開閉することになる。
【0003】
この場合、従来は図6に示すように下部スライドレールの走行時の安定性を確保するために、下部スライドレールの底面の幅方向二箇所に突起を形成し、この突起において下部レールの上面に接触させているが、下部レール上面の突起に対応した位置に、摩擦により突起の走行痕(傷)が下部スライドレールの走行範囲の全長に亘って発生するため、下部レール上面が露出する網戸の開放時に下部レールの見栄えの低下を招くことになる。このことは下部レールを着色した場合に顕著になる。
【0004】
また下部レールをサッシ枠の室内側に配置する場合に、サッシ枠内に収納される障子の形態によりサッシ枠の下枠に下部レールを突き合わせて敷設することができない場合には、下枠と下部レールとの間の隙間により床面が露出するため、開口部の意匠性が低下する。
【0005】
この発明は上記背景より、下部スライドレールが下部レール上を摺動する折り畳み式網戸において、走行痕の露出を回避し、また床面の露出を回避する下部スライドレールの支持構造を提案するものである。
【0006】
【課題を解決するための手段】
本発明は、開口部の下側に敷設された下部レール上に、折り畳み式網戸の戸先側に位置する下部スライドレールを摺動自在に支持させた支持構造であり、下部スライドレールは、下部レールの幅方向両側のそれぞれに位置する見付け片と、両見付け片をつなぐ見込み片から断面略H字状に形成され、両見付け片の下部には、それぞれ下部レールを幅方向両側から挟み込む形状の脚部が一体的に形成され、下部レールは幅方向両側に下部スライドレールの脚部が載る受け部と、受け部の上に位置し、受け部と共に凹溝を構成する保持部を有し、下部スライドレールの脚部は下部レールの前記凹溝内の前記保持部の下に入り込み、下部スライドレールの脚部の底面と下部レールの受け部の上面のいずれか一方に形成された凸部により、下部スライドレールの脚部の底面において前記受け部の上面に接触し、下部スライドレールの見込み片の底面と下部レールの上面とは非接触状態に保持されている折り畳み式網戸の支持構造であり、網戸の開放状態での下部スライドレールと下部レールの摺接部分の露出を回避し、下部レールの見栄えの低下を防止する。
【0007】
下部スライドレールの幅方向両側の脚部の底面と下部レールの受け部の上面とが接触することで、下部スライドレールが下部レール上を摺動することによる走行痕は受け部の上面、もしくは脚部の底面のいずれかに発生し、下部レール本体の上面への走行痕の発生は回避される。
【0008】
受け部に発生する場合でも、下部スライドレールの脚部が下部レールの凹溝内の保持部より奥側に入り込むことで、上方から見る限り、走行痕は保持部によって隠蔽され、露出しない。脚部に発生する場合は下部レール上を移動する側であることと、底面であることにより全く露出することがないため、いずれの場合も下部レールの見栄えを低下させることはなく、下部レールを着色した場合にも外観上は網戸の使用による変化を与えることがない。
【0009】
下部スライドレールの脚部は下部レールを幅方向両側から挟み込んだ状態でその底面において下部レールの受け部の上面と接触することで、下部レールの長さ方向に直交する断面上は二箇所で接触する。
【0010】
このため、例えば下部スライドレールの底面において下部レールの上面に面で接触する場合のようにいずれかの面の不陸による下部スライドレールの走行時の不安定性が問題になることはなく、下部スライドレールの安定性は確保されるが、特に本発明では、下部スライドレールの脚部の底面と、下部レールの受け部の上面のいずれか一方に凸部を形成し、断面上、完全に2点で接触させているため、下部スライドレールの走行時の安定性がより向上する。
【0011】
下部レールをサッシ枠の室内側に配置する場合で、サッシ枠内に収納される障子と網戸の走行位置の関係から、下部レールの本体を下枠に突き合わせて敷設することができない場合には、請求項2に記載のように下部レールの幅方向の片側に、床面を塞ぐ塞ぎ板を一体化させることにより下枠と下部レールとの間の隙間を塞ぎ、開口部の意匠性の低下を回避する。
【0012】
塞ぎ板はサッシ枠の下枠に突き当たることで、下部レールの敷設時に下枠に対して下部レールを位置決めする役目も持つため、請求項2では下部レール敷設時の位置決め作業がし易く、下部レールを正確に敷設できる利点がある。
【0013】
【発明の実施の形態】
この発明は図1,図2に示すようにサッシ枠11が収納される開口部の下側に敷設された下部レール9上に、折り畳み式の網戸1の戸先側に位置する下部スライドレール5を摺動自在に支持させる場合に、下部スライドレール5と下部レール9をその幅方向両側の二箇所で接触させたものである。
【0014】
網戸1の開閉を案内する下部レール9と上部レール10は図4,図5に示すようにそれぞれサッシ枠11の下枠12と上枠13に沿い、開口部の全幅に亘って敷設される。図面ではサッシ枠11内に、開放時に室外側へ張り出す折れ戸15を収納していることに伴い、下部レール9と上部レール10をサッシ枠11の室内側に敷設した場合を示しているが、室外側に敷設する場合もある。
【0015】
サッシ枠11の室内側に敷設する場合、下部レール9はサッシ枠11の縦枠14,14間、もしくは開口部を構成する柱16,16間等に亘り、床面17や窓台等に固定される。上部レール10は天井面18やまぐさ等に固定される。
【0016】
網戸1は図5に示すようにサッシ枠11の縦枠14、もしくは柱16等に固定される戸尻框2と、下部レール9上を移動する戸先框3と、両框2,3間に格納され、展開と折り畳みが自在なネット4から構成される。
【0017】
ネット4は図5に示すように網戸1の開放状態で、戸尻框2と戸先框3の互いに重なり合う見付け片2a,3a間で折り畳まれた状態にあり、戸先框3の閉鎖側への移動に伴って展開する。図面では同一面内に2組の網戸1,1を対向させて配置し、閉鎖時に双方の戸先框3,3を突き合わせるようにしているが、いずれか一方の縦枠14や柱16等にのみ戸尻框2を固定し、閉鎖時に対向する縦枠14や柱16等に戸先框3を突き合わせる場合もある。
【0018】
図4に示すように下部スライドレール5は戸先框3の下端に装着される下部キャップ6に取り付けられ、上部スライドレール7は戸先框3の上端に装着される上部キャップ8に取り付けられる。上部スライドレール7は上部レール10に幅方向両側から挟み込まれる形で上部レール10内に差し込まれ、幅方向の移動に対して拘束される。
【0019】
下部スライドレール5は下部レール9を幅方向両側から挟み込む脚部5a,5aを持ち、下部レール9は幅方向両側に下部スライドレール5の脚部5a,5aが載る受け部9a,9aと、各受け部9aの上に位置し、受け部9aと共に凹溝を構成する保持部9cを持ち、図1−(b) に示すように下部スライドレール5の各脚部5aは下部レール9の凹溝内の保持部9cより奥側に入り込み、底面において受け部9aの上面に接触する。脚部5aの底面全体は保持部9cの縁を通る鉛直線より凹溝の奥側に位置し、下部レール9を真上から見たとき、受け部9aの脚部5aとの接触面は保持部9cによって隠れる。
【0020】
下部スライドレール5の脚部5aは受け部9aと保持部9cとの間の凹溝内に差し込まれ、保持部9cによって浮き上がりに対して拘束される。凹溝に脚部5aが差し込まれた状態では脚部5aの上面と保持部9cの下面との間には下部スライドレール5の走行を阻害しない程度にクリアランスが確保される。
【0021】
下部スライドレール5は脚部5aが形成される見付け片51,51と両見付け片51,51をつなぐ見込み片52からH形に近い断面形状をし、下部レール9は脚部5a,5aに対応した断面形状をし、下部スライドレール5の見込み片52の底面と下部レール9の上面とは非接触状態に保たれる。下部スライドレール5と下部レール9はサッシ枠11と同様にアルミニウム合金の押出し成型により、または合成樹脂の押出し成型等により製作される。
【0022】
図1は下部スライドレール5の脚部5a,5aの底面を下部レール9の受け部9a,9aの上面に単純に接触させた場合を示す。この場合、脚部5aの底面と受け部9aの上面は面で接触することになるが、脚部5aの先端を角形や曲面に形成する等により断面上、点接触させることもできる。
【0023】
図2は下部レール9の受け部9aの上面に下部レール9の長さ方向に連続する凸部9bを形成し、下部スライドレール5の脚部5aの底面を受け部9aに断面上、点接触させ、下部スライドレール5の走行時の安定性をより高めた場合を示す。図2とは逆に、受け部9aの上面を平坦面にしたまま、上記のように脚部5aの先端を曲面等に形成し、凸部を脚部5aの底面に形成する場合もある。
【0024】
図1,図2はまた、下枠12の室内側の端部と下部レール9の本体との間に距離を確保する必要がある場合に、下部レール9の幅方向片側の、下枠12側の受け部9aに連続して床面17を塞ぐ塞ぎ板9dを一体化させ、下枠12と下部レール9との間で床面17を隠蔽した場合を示している。
【0025】
塞ぎ板9dを形成した場合、下部レール9は開口部に先行して設置されている下枠12の端部に塞ぎ板9dの下枠12側の端部を突き当てることで、下枠12に対して位置決めされた状態で床面17に固定される。
【0026】
【発明の効果】
折り畳み式網戸の戸先側に位置する下部スライドレールに、開口部の下側に敷設された下部レールを幅方向両側から挟み込む脚部を形成する一方、下部レールの幅方向両側に下部スライドレールの脚部が載る受け部と、受け部の上に位置し、受け部と共に凹溝を構成する保持部を形成し、下部スライドレールの脚部を下部レールの凹溝内の保持部より奥側に入り込ませ、底面において受け部の上面に接触させるため、網戸の開放状態での下部スライドレールと下部レールの摺接部分の露出が完全に回避され、下部レールの見栄えの低下を防止でき、下部レールを着色した場合にも外観上、変化を与えずに済む。
【0027】
また、本発明では、下部スライドレールの脚部の底面と、下部レールの受け部の上面のいずれか一方に凸部を形成し、断面上、完全に2点で接触させるため、下部スライドレールの走行時の安定性が向上する。
【0028】
請求項2では下部レールの幅方向の片側に、床面を塞ぐ塞ぎ板を一体化させることで下枠と下部レールとの間の隙間を塞ぐため、開口部の意匠性の低下を回避できる。
【0029】
また塞ぎ板がサッシ枠の下枠に突き当たることで、下部レールの敷設時に下枠に対して下部レールを位置決めできるため、下部レールの敷設作業がし易く、下部レールを正確に敷設できる。

BACKGROUND OF THE INVENTION
The present invention relates to a foldable screen door support structure in which a lower slide rail of a foldable screen door is slidably supported on a lower rail laid under the opening.
[0002]
[Prior art and problems to be solved by the invention]
Folding screen doors have upper and lower slide rails connected to the upper and lower ends of the door toe, and move along the upper and lower rails laid in parallel to the upper and lower sides of the opening. The door toe has a lower slide rail, except when the door toe is supported on the upper rail directly or through a wire or the like indirectly as in JP-A-8-121054. It opens and closes by sliding on the lower rail.
[0003]
In this case, conventionally, as shown in FIG. 6, in order to ensure the stability of the lower slide rail during running, protrusions are formed at two places in the width direction of the bottom surface of the lower slide rail, and these protrusions are formed on the upper surface of the lower rail. Although the contact mark is in contact with the protrusion on the upper surface of the lower rail, a running mark (scratch) of the protrusion is generated over the entire length of the lower slide rail due to friction. When opened, the appearance of the lower rail will be reduced. This becomes prominent when the lower rail is colored.
[0004]
When the lower rail is placed on the indoor side of the sash frame, if the lower rail cannot be laid against the lower frame of the sash frame due to the form of the shoji stored in the sash frame, Since the floor surface is exposed by the gap between the rails, the design of the opening is deteriorated.
[0005]
The present invention proposes a support structure for the lower slide rail that avoids the exposure of the running trace and the exposure of the floor surface in the folding screen door in which the lower slide rail slides on the lower rail. is there.
[0006]
[Means for Solving the Problems]
The present invention is a support structure in which a lower slide rail positioned on the door end side of a folding screen door is slidably supported on a lower rail laid on the lower side of the opening, It is formed in a substantially H-shaped cross section from a finding piece located on each side of the rail in the width direction and a prospective piece connecting both finding pieces, and the lower rail is sandwiched from both sides in the width direction at the bottom of both finding pieces. The leg is formed integrally, the lower rail has a receiving part on which the leg part of the lower slide rail rests on both sides in the width direction, and a holding part that is located on the receiving part and forms a concave groove with the receiving part, A leg portion of the lower slide rail enters under the holding portion in the concave groove of the lower rail, and is formed by a convex portion formed on either the bottom surface of the lower slide rail leg portion or the upper surface of the lower rail receiving portion. , Lower sly Contact with the upper surface of the receiving portion in the bottom surface of the leg portion of the rail, the upper surface of the bottom and the lower rail prospective piece of the lower slide rail is a support structure for folding screen door, which is held in a non-contact state, the screens Exposure of the sliding portion of the lower slide rail and the lower rail in the open state is avoided, and deterioration of the appearance of the lower rail is prevented.
[0007]
When the bottom surface of the leg on both sides in the width direction of the lower slide rail comes into contact with the upper surface of the receiving portion of the lower rail, the running trace due to the lower slide rail sliding on the lower rail is the upper surface of the receiving portion or the leg. Occurrence of a running mark on the upper surface of the lower rail body is avoided.
[0008]
Even if it occurs in the receiving part, the leg of the lower slide rail enters the back side from the holding part in the concave groove of the lower rail, so that the running trace is concealed by the holding part and is not exposed as far as seen from above. If it occurs on the leg, it will not be exposed at all because it is on the side that moves on the lower rail and on the bottom, so the appearance of the lower rail will not be degraded in either case, Even when it is colored, there is no change in appearance due to the use of screen doors.
[0009]
The legs of the lower slide rail are in contact with the upper surface of the receiving part of the lower rail at the bottom surface with the lower rail sandwiched from both sides in the width direction, so that the cross section perpendicular to the length direction of the lower rail contacts at two places. To do.
[0010]
For this reason, for example, when the bottom surface of the lower slide rail is in contact with the upper surface of the lower rail, the instability of the lower slide rail due to unevenness of either surface does not become a problem, and the lower slide Although the rail stability is ensured, in the present invention , in particular, a convex portion is formed on one of the bottom surface of the leg portion of the lower slide rail and the upper surface of the receiving portion of the lower rail. in order that in contact, running stability of the lower slide rail is further improved.
[0011]
When placing the lower rail on the indoor side of the sash frame, and if the lower rail body cannot be laid against the lower frame due to the relationship between the shoji and the screen door stored in the sash frame, The gap between the lower frame and the lower rail is closed by integrating a closing plate that closes the floor surface on one side in the width direction of the lower rail as described in claim 2 , thereby reducing the design of the opening. To avoid.
[0012]
The closing plate that abuts the lower frame of the sash frame, to have also serves to position the lower rail relative to the lower frame during laying of the lower rail, facilitate the positioning operation during claim 2, the lower rail laying, lower rail There is an advantage that can be laid accurately.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 and 2, the present invention has a lower slide rail 5 positioned on a door end side of a folding screen door 1 on a lower rail 9 laid on the lower side of an opening in which a sash frame 11 is accommodated.

[0017]
As shown in FIG. 5, the net 4 is in a state where the screen door 1 is opened and is folded between the overlapping pieces 2 a and 3 a of the door-toe 2 and the door-toe 3 to the closed side of the door-toe 3. Expands with the movement of. In the drawing, two sets of screen doors 1 and 1 are arranged facing each other in the same plane so that the door end walls 3 and 3 face each other when closed. There is a case in which the door toe 2 is fixed only to the top and the door toe 3 is abutted against the vertical frame 14 or the column 16 which is opposed when closed.
[0018]
As shown in FIG. 4, the lower slide rail 5 is attached to the lower cap 6 attached to the lower end of the door toe 3, and the upper slide rail 7 is attached to the upper cap 8 attached to the upper end of the door toe 3. The upper slide rail 7 is inserted into the upper rail 10 so as to be sandwiched by the upper rail 10 from both sides in the width direction, and is restrained against movement in the width direction.
[0019]
The lower slide rail 5 has legs 5a and 5a for sandwiching the lower rail 9 from both sides in the width direction. The lower rail 9 has receiving parts 9a and 9a on which the legs 5a and 5a of the lower slide rail 5 are placed on both sides in the width direction. It has a holding part 9c which is located on the receiving part 9a and forms a concave groove together with the receiving part 9a, and each leg part 5a of the lower slide rail 5 is a concave groove of the lower rail 9 as shown in FIG. It enters the back side from the inner holding portion 9c and contacts the upper surface of the receiving portion 9a at the bottom surface. The entire bottom surface of the leg portion 5a is located on the back side of the groove from the vertical line passing through the edge of the holding portion 9c, and when the lower rail 9 is viewed from directly above, the contact surface with the leg portion 5a of the receiving portion 9a is held. Hidden by part 9c.
[0020]
The leg portion 5a of the lower slide rail 5 is inserted into a concave groove between the receiving portion 9a and the holding portion 9c, and is restrained against lifting by the holding portion 9c. In a state where the leg portion 5a is inserted into the concave groove, a clearance is secured between the upper surface of the leg portion 5a and the lower surface of the holding portion 9c to such an extent that the travel of the lower slide rail 5 is not hindered.
[0021]
The lower slide rail 5 has a cross-sectional shape close to an H shape from the finding piece 51, 51 on which the leg portion 5a is formed and the prospective piece 52 connecting the both finding pieces 51, 51, and the lower rail 9 corresponds to the leg portions 5a, 5a. The bottom surface of the prospective piece 52 of the lower slide rail 5 and the upper surface of the lower rail 9 are kept in a non-contact state. Similarly to the sash frame 11, the lower slide rail 5 and the lower rail 9 are manufactured by extrusion molding of an aluminum alloy or by extrusion molding of a synthetic resin.
[0022]
FIG. 1 shows a case where the bottom surfaces of the legs 5a, 5a of the lower slide rail 5 are simply brought into contact with the upper surfaces of the receiving portions 9a, 9a of the lower rail 9. In this case, the bottom surface of the leg portion 5a and the upper surface of the receiving portion 9a are in contact with each other by surface, but it is also possible to make point contact on the cross section by forming the tip of the leg portion 5a into a square shape or a curved surface.
