The

滑車2は、例えば、合成樹脂や金属等からなるディスクであって、その全周面に、障子が嵌まる戸枠1の案内レール1aと係合する一条の凹溝2aが形成され、滑車2の中央に、必要に応じて転がり軸受けを装着するものである。   The pulley 2 is, for example, a disc made of synthetic resin, metal, or the like, and a single groove 2a that engages with the guide rail 1a of the door frame 1 into which the shoji is fitted is formed on the entire circumferential surface thereof. A rolling bearing is mounted at the center of the roller as necessary.

凹溝2aは、滑車2の適正な揺動を許容出来る様に、案内レール1aの頂き部よりも僅かに幅広い開口部が与えられている。更に、当該障子の施錠時における揺動に対しても急激な挙動(位置・姿勢変異等)を伴わず滑らかに追従出来るように、その底面(踏面)が左右対称な曲面となっており、その深さは、前記許容された揺動によっても脱線しない程度の十分な深さに設定されている(図1(B)、図2(B)、又は図3若しくは図4参照)。   The concave groove 2a is provided with an opening that is slightly wider than the receiving portion of the guide rail 1a so as to allow proper swinging of the pulley 2. Furthermore, the bottom surface (tread surface) is a symmetrical curved surface so that it can follow smoothly without abrupt behavior (position / posture variation, etc.) even when the shoji is locked. The depth is set to a sufficient depth so as not to derail even by the allowable swing (see FIG. 1B, FIG. 2B, FIG. 3 or FIG. 4).

内フレーム3は、方形状のステンレス板をコの字状に折り曲げることによって、相対向する左右一対の支持板3b,3bと、それらを連結する受圧板3cを形成したものである(図6(C)(D)参照)。   The inner frame 3 is formed by bending a rectangular stainless steel plate into a U-shape to form a pair of left and right support plates 3b, 3b facing each other and a pressure receiving plate 3c connecting them (FIG. 6 ( C) (see D)).

左右支持板3b,3bは、滑車2の車軸6を支持すべく、車軸6の両端を支える軸孔を軸承部3aに備える。
また、左右支持板3b,3bは、外フレーム5に対する内フレーム3の揺動の支点となる円筒状の支軸3dを対照的に備え、少なくとも一方の支持板3bは、外フレーム5に対する内フレーム3の揺動を規制するガイド3eを備える。支軸3dは、円形孔の周縁が外フレーム5の表面に略露出し得る程度だけ、外側へ円筒状に脱出したものであり、ガイド3eは、支持板3bの内側から表側へ墳状に膨出したものである(図6(C)(D)参照)。
The left and right support plates 3b, 3b are provided with a shaft hole for supporting both ends of the axle 6 in the bearing portion 3a in order to support the axle 6 of the pulley 2.
The left and right support plates 3b and 3b are provided with a cylindrical support shaft 3d as a fulcrum for the swing of the inner frame 3 with respect to the outer frame 5, and at least one of the support plates 3b is an inner frame with respect to the outer frame 5. 3 is provided. The support shaft 3d has a cylindrical shape that protrudes outwardly to the extent that the peripheral edge of the circular hole can be substantially exposed on the surface of the outer frame 5, and the guide 3e swells in a bowl shape from the inside to the front side of the support plate 3b. (See FIGS. 6C and 6D).

外フレーム5は、左右側板5b,5b、左右側板5b,5bの連結部を円弧状に湾曲させ一部に間欠部を設けた天板5c、及び左右側板5b,5bの後部を各々直角に折り重ねてなる背板5dを、ステンレス板からなる一枚の部材を折り曲げ、且つ背板5d,5dの重合部にかみ合わせ部5eを設けて一体化することにより、前記内フレーム3を装填する為の開口部を前方及び下方に具備した箱状に成形してなるものである(図6(A)(B)参照)。   The outer frame 5 is formed by bending the left and right side plates 5b and 5b, the connecting portions of the left and right side plates 5b and 5b in a circular arc shape, and folding the rear portions of the left and right side plates 5b and 5b at right angles. For folding the back plate 5d, the inner frame 3 is loaded by bending a single member made of a stainless steel plate and integrating the back plate 5d, 5d with the engagement portion 5e. It is formed into a box shape having openings at the front and the bottom (see FIGS. 6A and 6B).

更に、外フレーム5は、その上部に障子の下枠4に固定する為の弾性フック7を一体的に備える。
弾性フック7は、ヘアピン状の弾性金属片であって、当該弾性フック7のUターン部を境とする一片を、背板5dの上方に設けた開口部から差し入れつつ両片で天板5cを挟む様に装着し、外フレーム5の内部(天板5cの下位)に存在する一片を当該天板5cに溶着することにより外フレーム5と接合する。
Further, the outer frame 5 is integrally provided with an elastic hook 7 for fixing to the lower frame 4 of the shoji at the upper part.
The elastic hook 7 is an elastic metal piece in the form of a hairpin, and the top plate 5c is inserted into one piece with the U-turn portion of the elastic hook 7 as a boundary through an opening provided above the back plate 5d. It mounts | wears so that it may pinch | interpose and it joins with the outer frame 5 by welding the piece which exists inside the outer frame 5 (lower layer of the top plate 5c) to the said top plate 5c.

外フレーム5の左右側板5b,5bの後方下部は、内フレーム3の支軸3d,3dを受ける支軸受け5f,5fを各々相対向して備え、少なくとも一方の側板5bは、当該支軸受け5fから一定の距離を保って円弧状に湾曲するガイド受け5gを備える。
支軸受け5fは、内フレーム3の支軸3dを装脱するための切欠部を備え、ガイド受け5gは、内フレーム3のガイド3eの軌道を規制し、外フレーム5に対する内フレーム3の揺動角(滑車の出没)を規制する。
The lower rear portions of the left and right side plates 5b, 5b of the outer frame 5 are respectively provided with bearings 5f, 5f that receive the supporting shafts 3d, 3d of the inner frame 3, so that at least one side plate 5b extends from the supporting bearings 5f. A guide receiver 5g that is curved in an arc shape with a constant distance is provided.
The support bearing 5f includes a notch for attaching / detaching the support shaft 3d of the inner frame 3, and the guide receiver 5g regulates the track of the guide 3e of the inner frame 3 and swings the inner frame 3 with respect to the outer frame 5. Regulate corners (invitation and departure of pulleys).

更に、外フレーム5は、支持した内フレーム3の沈み込み量を制限すべく、その内部に内フレーム3の左右支持板3b,3bの上縁を制止するストッパー5i,5iを備える。当該例におけるストッパー5iは、外フレーム5の左右側板5b,5bの間隔を一部狭くすることにより内フレーム3の進入を押し止めるものである。当該例のストッパー5iは、外フレーム5の上部を内フレーム3の幅より狭くなるように外側から加圧して陥没させたものであって、前記天板5cの間欠部の下方一定領域にのみ備える。   Further, the outer frame 5 is provided with stoppers 5i and 5i for restraining the upper edges of the left and right support plates 3b and 3b of the inner frame 3 in order to limit the sinking amount of the supported inner frame 3. The stopper 5i in this example is to prevent the inner frame 3 from entering by partially narrowing the distance between the left and right side plates 5b, 5b of the outer frame 5. The stopper 5i in this example is a part in which the upper part of the outer frame 5 is depressed from the outside so as to be narrower than the width of the inner frame 3, and is provided only in a fixed region below the intermittent part of the top plate 5c. .

外フレーム5の背板5dは、上部にねじ孔5hを備え、内フレーム3の受圧板3cを支持するネジ9が螺合する。当該ネジ9の進退を調整することを以って、当該戸車を備えた障子の支持高が設定されることとなる(図5(D)及び(E)参照)。   The back plate 5d of the outer frame 5 is provided with a screw hole 5h in the upper portion, and screws 9 that support the pressure receiving plate 3c of the inner frame 3 are screwed together. By adjusting the advance / retreat of the screw 9, the support height of the shoji equipped with the door wheel is set (see FIGS. 5D and 5E).

当該例における弾性フック7は、その先端部(場合によっては、中間部など他の領域に設けても良い。)に突っ張り片7aを備える。
当該例における突っ張り片7aの存在意義は、障子の下枠4に位置決めされた戸車を定位置に支持し、その結果、戸車の揺動の中心を安定させること、及び突っ張り片7aと下枠4の内側面との接点を支点として戸車に対して下枠4の起立状態への復元力を与える弾性を確保することにある。
The elastic hook 7 in this example is provided with a tension piece 7a at the tip thereof (in some cases, it may be provided in another region such as an intermediate portion).
The significance of the tension piece 7a in this example is that the door wheel positioned on the lower frame 4 of the shoji is supported at a fixed position, and as a result, the center of swinging of the door wheel is stabilized, and the tension piece 7a and the lower frame 4 are supported. It is to ensure elasticity that gives a restoring force of the lower frame 4 to the standing state with respect to the door wheel with a contact point with the inner surface of the door frame as a fulcrum.

弾性フック7の突っ張り片7aの先端左右への迫り出し長は、下枠4の全幅に対する戸車の固定位置と、戸車の左右双方への揺動量の限界を定めるものである。即ち、戸車の揺動量は、他に戸車を支持固定する手段を設けない限りにおいて、迫り出しの少ない方向より迫り出しの多い方向への方が大きくなる。   The protruding length of the elastic hook 7 to the left and right ends of the projecting piece 7a determines the fixed position of the door wheel with respect to the entire width of the lower frame 4 and the limit of the amount of swinging of the door wheel to the left and right. That is, the amount of rocking of the door roller is greater in the direction in which there is more protrusion than in the direction in which there is less protrusion unless another means for supporting and fixing the door wheel is provided.

下枠4の下面左右いずれかに寄せて戸車を位置せしめる場合には、下枠4の側板の内側面で、一方への揺動が禁止されるので、突っ張り片7aの迫り出しは、揺動が許容される方向に備えれば良く、その迫り出し長は、当該方向の側板に突っ張り片7aの側縁が接する長さであれば良い。   When the door is positioned close to the left or right side of the lower frame 4, swinging to one side is prohibited on the inner surface of the side plate of the lower frame 4. The protrusion length may be any length as long as the side edge of the projecting piece 7a contacts the side plate in that direction.

別途、戸車を支持固定する手段として、下枠4の下面に前記戸車の突曲面5aが相補的に納まる半円弧状の凹曲面4aを備えれば、下枠4に対する戸車の揺動軸が固定され、施錠時の位置及び姿勢、並びに開閉時の安定性が高まる他、障子から外フレーム5の突曲面にかかる荷重が分散し、戸車の耐荷重性を高めることができる。   Separately, as a means for supporting and fixing the door roller, if the lower surface of the lower frame 4 is provided with a semicircular arc-shaped concave surface 4a in which the protruding surface 5a of the door wheel is complementarily accommodated, the swing shaft of the door wheel relative to the lower frame 4 is fixed. In addition, the position and posture at the time of locking and the stability at the time of opening and closing are increased, and the load applied from the shoji to the projecting curved surface of the outer frame 5 is dispersed, so that the load resistance of the door wheel can be improved.

弾性フック7は、外フレームの長さと略等しい長さとする。
弾性フック7の弾性は、幅広な突っ張り片7aの範囲を長手方向へ広げることにより増加させることができる。
The elastic hook 7 has a length substantially equal to the length of the outer frame.
The elasticity of the elastic hook 7 can be increased by expanding the range of the wide tension piece 7a in the longitudinal direction.

本考案による戸車は以上のごとく構成され、下枠4の端面から当該下枠4の空隙へ戸車を差し入れ、その際、弾性フック7を下枠4の横板4bに引っ掛けることにより、当該戸車は下枠4に接した形で固定され、当該下枠4の端面に縦枠4cを固定することで、下枠4からの戸車の離脱を防止する。   The door wheel according to the present invention is configured as described above, and the door wheel is inserted into the gap of the lower frame 4 from the end face of the lower frame 4, and at that time the elastic hook 7 is hooked on the horizontal plate 4 b of the lower frame 4. By fixing the frame 4c in contact with the lower frame 4 and fixing the vertical frame 4c to the end face of the lower frame 4, the detachment of the door from the lower frame 4 is prevented.

図1乃至図4の例にあっては、戸車は、下枠4の凹曲面4aに、戸車の突曲面5aを装填することによって下枠4の空隙における片側へ寄せて固定される。
施錠時にあっては、戸車に許容された揺動を以て、障子が、施錠されていない時の案内位置より数mmから数cm程度、躯体の戸枠1側へ向けて水平方向へ移動し、その結果、戸枠1にシール部が密着することにより機密性が高められ(図3(B)及び図4(B)参照)ると共に、上下左右の振れを生じることなく安定して支持される。
In the example of FIGS. 1 to 4, the door roller is fixed to one side of the gap in the lower frame 4 by loading the concave curved surface 4 a of the lower frame 4 with the protruding curved surface 5 a of the door wheel.
At the time of locking, the shoji moves in the horizontal direction toward the door frame 1 side of the frame about several millimeters to several centimeters from the guide position when the door is not locked. As a result, when the seal portion is in close contact with the door frame 1, confidentiality is enhanced (see FIGS. 3B and 4B), and the door frame 1 is stably supported without causing up-down and left-right swings.

また、弾性フック7で吊られた戸車が、弾性的に左右に振れる事も可能となっているので、湾曲した案内レール1aに対しても無理なく追従でき、また、その際に、軸孔や車軸6に対する負荷も好適にやわらげることが出来るので、それらの部位の消耗も抑制でき、その簡素な構成とも相俟って長期にわたって安定した機能を果たすことが可能となる。   Further, since the door wheel suspended by the elastic hook 7 can elastically swing left and right, it can follow the curved guide rail 1a without difficulty. Since the load on the axle 6 can be suitably reduced, the consumption of those parts can be suppressed, and it is possible to perform a stable function for a long time in combination with the simple configuration.

本考案による戸車は、外フレーム5の側板5bに、下枠4の内側面に当接する板ばね8の一端部を溶着する構造とすることもできる。
図3及び図4に示す例は、戸車が起立姿勢にある状態において障子の開閉が行われ、戸車が傾斜姿勢にある状態において障子の施錠を行う構成である。
The door wheel according to the present invention may have a structure in which one end of the leaf spring 8 that contacts the inner surface of the lower frame 4 is welded to the side plate 5 b of the outer frame 5.
The example shown in FIG.3 and FIG.4 is a structure which opens and closes a shoji in the state which has a door pulley in the standing position, and locks a shoji in the state in which the door wheel is in a tilting posture.

図3は、起立姿勢に誘導する方向へ付勢する様に板ばね8を設けた例であり、図4は、傾斜状態に誘導する方向へ付勢する様に板ばね8を設けた例である。
前者の構成(図3参照)によって、障子の開閉状態における起立姿勢の安定性が高まり、後者(図4参照)の構成によって、施錠する際における戸枠1への障子の密着力が、板ばね8の作用により高められることになる。
FIG. 3 is an example in which the leaf spring 8 is provided so as to be biased in a direction to be guided to a standing posture, and FIG. 4 is an example in which the leaf spring 8 is provided so as to be biased in a direction to be guided in an inclined state. is there.
The former configuration (see FIG. 3) increases the stability of the standing posture in the open / close state of the shoji, and the latter (see FIG. 4) improves the contact force of the shoji to the door frame 1 during locking. It is raised by the action of 8.

尚、板ばね8を設ける手法は、上記の如く別途溶接する手法に限らず、外フレーム5の側板の一部に板状の切り込みを入れ、連結部分を折代として側方へ開き出すことを以って形成しても良い。   The method of providing the leaf spring 8 is not limited to the method of welding separately as described above, and a plate-like cut is made in a part of the side plate of the outer frame 5, and the connecting portion is opened to the side as a folding margin. Therefore, it may be formed.
