Description

この発明は、大型窓の開閉金具（以下単に開閉金具という）に係り、特に、円滑に作動し、窓の開閉に要する作動力を小さくすることができる開閉金具に関する。   The present invention relates to an opening / closing bracket for a large window (hereinafter simply referred to as an opening / closing bracket), and more particularly to an opening / closing bracket that operates smoothly and can reduce the operating force required to open and close a window.

本出願人等は、先に、後記特許文献１を以て、新規なルーバー窓用の開閉金具を提案した。   The present applicants have previously proposed a novel opening / closing metal fitting for a louver window using Patent Document 1 described later.

この開閉金具は、ハンドル操作により窓の縦枠に沿って上下方向に案内駆動される連動棒に、窓枠開口部の上下方向に並設された複数のルーバーを連動用係合軸により係合して、上記連動棒の上下方向移動により複数のルーバーを連動して開閉するようにしたルーバー窓において、ルーバーの側端縁下部および連動棒の何れか一方にロックピンを他方に向け突出させて固設し、この他方に、ロックピンと摺接して係合能な係止端縁を有する係止片を装着すると共に、上記連動用係合軸と係合する連動棒およびルーバーの側端縁の何れか一方に、上下方向に長い長孔を形成し、上記ロックピンおよび係止片の係脱に要する連動棒の移動行程中は連動用係合軸を長孔中で遊動させるようにしたことを特徴とするものである。
実公平７−３４１３３号公報 This open / close bracket engages a plurality of louvers juxtaposed in the vertical direction of the window frame opening with an interlocking engagement shaft on an interlocking rod that is guided and driven in the vertical direction along the vertical frame of the window by a handle operation. In the louver window that opens and closes a plurality of louvers by moving the interlocking bar in the vertical direction, a lock pin protrudes toward the other of the lower part of the side edge of the louver and the interlocking bar. On the other side, a locking piece having a locking end edge that is slidably contacted with the lock pin is mounted, and a side edge of the interlocking rod and the louver that engages with the interlocking engagement shaft. Either one of them has a long hole in the vertical direction, and the interlocking engagement shaft is allowed to move freely in the long hole during the movement stroke of the interlocking rod required to engage and disengage the lock pin and the locking piece. It is characterized by.
No. 7-34133

上記した構成のルーバー窓用の開閉金具は、各ルーバーが揺動する支持レバーの自由端に設けられた揺動軸に支持されて外側に振出されると共に、揺動軸を中心とする挺子のように回動し、また、上記挺子の力点となる上記連動用係合軸と挺子の中心とな揺動軸との間隔が小さい。   The opening / closing bracket for a louver window having the above-described structure is supported by a swing shaft provided at the free end of a support lever on which each louver swings, and swings outward, and is an insulator centered on the swing shaft. In addition, the distance between the interlocking engagement shaft, which is the power point of the lever, and the center of the lever and the swing shaft is small.

そのため、ルーバー窓のように上下方向の寸法が小さい場合は兎も角、大型の窓の開閉金具としてこの開閉金具の構造を採用すると、開閉操作力が大きくなり、作動が円滑でなくなる、という不都合がある。   Therefore, when the vertical dimension is small, such as a louver window, the use of this opening / closing bracket structure as a large window opening / closing bracket increases the opening / closing operation force, and the operation is not smooth. There is.

そこで、この発明は、ルーバー窓開閉金具を改良して、円滑に作動し、かつ窓の開閉に要する作動力を小さくすることができる開閉金具を提供することを目的としている。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an opening / closing bracket that improves the louver window opening / closing bracket and can operate smoothly and reduce the operating force required to open / close the window.

上記の目的を達成するため、この発明は、ハンドル操作によって窓の縦枠に沿って上下方向に移動可能に案内駆動される連動杆と、基端を窓の縦枠に回動可能に支承され、自由端を障子の側端縁にリンク結合させた支持レバーと、障子の側端縁の一端部においてその長さ方向に沿い、かつ連動杆に向かって突設された連動用係合軸及びガイドピンと、この連動用係合軸及びガイドピンに対向するような相対位置関係で連動杆に配設され、上記連動用係合軸及びガイドピンに対応して、上下方向に長い長孔、及び上下方向の長穴及び円弧孔を連設した全体の形状が略くの字形の逃げ孔とを開口させた係合板とを有し、障子の側端縁のガイドピンより他端側の部分及び連動杆の何れか一方にロックピンを他方に向け突出させて固設し、他方に、ロックピンと摺接して係合可能な係止端縁を有する係止片を装着すると共に、上記連動用係合軸と係合板の長孔、及び、ガイドピンと逃げ孔とを夫々摺動可能に係合させ、上記ロックピンおよび係止片の係脱に要する連動杆の移動行程中は連動用係合軸を長孔中で遊動させるようにし、一方、上記支持レバーの基端の位置を縦枠の中央部に、自由端の揺動軸を障子の側端縁の中央より一端側に設定したことを特徴とする。   In order to achieve the above object, the present invention is supported by an interlocking rod that is guided and driven so as to be movable in the vertical direction along the vertical frame of the window by a handle operation, and is pivotally supported by the vertical frame of the window. A support lever having a free end linked to the side edge of the shoji, an interlocking engagement shaft projecting along the length direction at one end of the side edge of the shoji, and projecting toward the interlocking hook; The guide pin is disposed in the interlocking rod in a relative positional relationship so as to face the interlocking engagement shaft and the guide pin, and corresponds to the interlocking engagement shaft and the guide pin. An engagement plate having a generally U-shaped escape hole in which an overall elongated hole and an arc hole are continuously provided, and a portion on the other end side from the guide pin on the side edge of the shoji, A lock pin protrudes from one of the interlocking rods toward the other side, and is fixed to the other side. A locking piece having a locking end edge that can be slidably engaged with the cup pin is mounted, and the interlocking engagement shaft and the long hole of the engagement plate, and the guide pin and the escape hole are slidably engaged. The interlocking engagement shaft is allowed to move freely in the long hole during the movement stroke of the interlocking rod required to engage and disengage the lock pin and the locking piece, while the base end position of the support lever is The swinging shaft at the free end is set at one end side from the center of the side edge of the shoji at the central portion of the sliding door.

上記のように構成されたこの発明による開閉金具は、障子を担持する揺動軸と、障子を開閉する挺子の力点となる連動用係合軸との距離を長くしたので、重量の大きな大型窓の開閉に要する作動力が小さくなり、かつ、開閉動作が円滑になる、という所期の効果を奏する。   The opening / closing bracket according to the present invention configured as described above has a large and large weight because the distance between the swing shaft that carries the shoji and the interlocking engagement shaft that is the power point of the shoji that opens and closes the shoji is increased. There is an expected effect that the operating force required for opening and closing the window is reduced and the opening and closing operation is smooth.

障子を担持する揺動軸と、障子を開閉する挺子の力点となる連動用係合軸との距離を長くする、という簡単な構成で、ルーバー窓の開閉金具を大型窓の開閉金具に転用することかできた。   The louver window opening / closing bracket can be used as a large window opening / closing bracket with a simple configuration that increases the distance between the swing shaft that holds the sliding door and the interlocking engagement shaft, which is the power point of the lever that opens and closes the sliding door. I was able to do it.

以下、この発明の一実施例を図面を参照して説明する。
なお、以下の説明において障子及び窓枠からなる大型窓の基本的な構成は前記特許文献１に記載のルーバー窓のそれと同様であるから、簡単に説明する。 An embodiment of the present invention will be described below with reference to the drawings.
In the following description, the basic configuration of a large window composed of a shoji and a window frame is the same as that of the louver window described in Patent Document 1, and will be described briefly.

図１において符号１は例えばオーニング窓のような大型窓の窓枠の外面から見て右側の縦枠を示し、この縦枠１内には、これとほぼ平行で板状の連動杆２が縦枠１の長さ方向、すなわち上下方向に移動可能に案内されている。   In FIG. 1, reference numeral 1 indicates a vertical frame on the right side when viewed from the outer surface of a window frame of a large window such as an awning window. In this vertical frame 1, a plate-like interlocking rod 2 that is substantially parallel to the vertical frame is provided. The frame 1 is guided so as to be movable in the length direction, that is, in the vertical direction.

この連動杆２の下端部は、第２リンクレバー３を介して、第１リンクレバー４の自由端にリンク結合されており、上記第１リンクレバー４の基端は、横断面異形の連結バー５の一端に、当該連結バー回りの回動を拘束された状態で結合されている。   The lower end portion of the interlocking rod 2 is linked to the free end of the first link lever 4 via the second link lever 3, and the base end of the first link lever 4 is a connecting bar having an irregular cross section. It is connected to one end of 5 in a state where the rotation around the connecting bar is constrained.

なお、上記第１および第２リンクレバー４、３および連動杆２は一種のスライダクランク機構を構成し、第１リンクレバー４が回動すれば連動杆２はその長さ方向に沿って上下動する。   The first and second link levers 4 and 3 and the interlocking rod 2 constitute a kind of slider crank mechanism. When the first link lever 4 rotates, the interlocking rod 2 moves up and down along its length direction. To do.

一方、上記連結バー５は窓枠の下枠６に沿って延在する棒状体であって、図示しないその他端には、第１図とは対称的に同大同形の他の図示しない第１リンクレバー４の基端が結合され、その第１リンクレバー４の自由端は、同様にして第２リンクレバーを介して図示しないもう１本の連動杆の下端部にリンク結合されている。   On the other hand, the connecting bar 5 is a rod-like body extending along the lower frame 6 of the window frame. The base end of the link lever 4 is coupled, and the free end of the first link lever 4 is similarly linked to the lower end of another interlocking rod (not shown) via the second link lever.

すなわち、連動杆２は窓枠の左右の縦枠に１本づつ設けられており、これら一対の連動杆２、２は、連結バー５の回動により、一体的に連動して上下動する。   That is, the interlocking rods 2 are provided one by one in the left and right vertical frames of the window frame, and the pair of interlocking rods 2 and 2 move up and down integrally in conjunction with the rotation of the connecting bar 5.

上記連結バー５を駆動するため、第１図に示すように、縦枠１の下端部に図示しないギアボックス及び操作ハンドルが設けられている。   In order to drive the connecting bar 5, a gear box and an operation handle (not shown) are provided at the lower end of the vertical frame 1, as shown in FIG.

操作ハンドルの内端には例えばウォーム（図示せず）が装着されており、このウォームは、ギアボックス内に回動自在に支承された図示しないウォームギアと噛み合っている。   For example, a worm (not shown) is mounted on the inner end of the operation handle, and this worm meshes with a worm gear (not shown) rotatably supported in a gear box.

そして、このウォームに結合されたダルマ形の駆動板７の突出部は、作動レバー８を介して、前記第１及び第２リンクレバー４、３の結合ピン９にリンク結合されている。   The protruding portion of the Dalma-shaped drive plate 7 coupled to the worm is linked to the coupling pin 9 of the first and second link levers 4 and 3 via the operating lever 8.

なお、図１に示す実施例では、結合ピン９と駆動板７の突出部との間にもう１本のレバーが有るように描かれているが、このレバーは図１で向う側の縦枠に設けられた大型窓施錠用のレバーであって、この発明と関係がないので、更に詳細な説明は省略する。   In the embodiment shown in FIG. 1, it is depicted that there is another lever between the coupling pin 9 and the protruding portion of the drive plate 7, but this lever is formed in a vertical frame on the opposite side in FIG. Since it is a lever for locking a large window provided and is not related to the present invention, further detailed description is omitted.

上記した構成により、操作ハンドル８の回動は減速されて第１作動レバー９に伝達され、さらに第２作動レバー１０の長さ方向の移動に変換されて前記スライダクランク機構に伝わり、連動杆２の上下動に変換される。この連動杆２の動きは、連結バー５を介して、対をなす他方の連動杆にも伝達されるヒとは前記したとおりである。 With the above-described configuration, the rotation of the operation handle 8 is decelerated and transmitted to the first operating lever 9, and further converted into a movement in the length direction of the second operating lever 10 and transmitted to the slider crank mechanism. Is converted to vertical movement. The movement of the interlocking rod 2 is transmitted to the other interlocking rod paired via the connecting bar 5 as described above.

一方、窓枠の外面側（図１で左側）には、大型窓の障子１１が上端を中心にして外側に振出し可能に案内されて装着されている。   On the other hand, on the outer surface side (left side in FIG. 1) of the window frame, a shoji 11 of a large window is guided and mounted so as to be able to swing outward with the upper end as the center.

図示の実施例における障子１１は、例えばガラス板の外辺部をアルミ引抜材で縁取った板状体である。   The shoji 11 in the illustrated embodiment is, for example, a plate-like body having an outer edge portion of a glass plate edged with an aluminum drawing material.

そして、図１に示すように、上記障子１１の各側端縁の上方から約１／３の長さの部分に、保持板１２を介して、揺動軸１４が植設されており、この揺動軸１４は、支持レバー１５を介して、縦枠１の中央部における固定部にリンク結合されている。   As shown in FIG. 1, a swing shaft 14 is implanted through a holding plate 12 in a portion having a length of about 1/3 from above each side edge of the shoji 11. The swing shaft 14 is linked to a fixed portion at the center of the vertical frame 1 via a support lever 15.

上記の構成により、障子１１は、揺動軸１４、１４及び支持レバー１５、１５を介して、縦枠１に回動可能に支承されることになる。   With the above configuration, the shoji 11 is rotatably supported by the vertical frame 1 via the swing shafts 14 and 14 and the support levers 15 and 15.

また、上記障子１１の各側端縁上端部には、図１乃至図３に示すように、全体の形状が略Ｊ字形の段付板状体である支持片１３が装着されている。   Further, as shown in FIGS. 1 to 3, a support piece 13, which is a stepped plate-like body having a substantially J-shape as a whole, is attached to the upper edge of each side edge of the shoji 11.

そして、各支持片１３の上端には連動用係合軸１６及びガイドピン１７（図２及び図３参照）が植設されており、これらのピンはそれぞれ連動杆２に臨んでいる。   An interlocking engagement shaft 16 and a guide pin 17 (see FIGS. 2 and 3) are planted at the upper end of each support piece 13, and these pins respectively face the interlocking rod 2.

これら連動用係合軸１６及びガイドピン１７に対向する連動杆２の部分には段付の係合板１８が装着されており、この係合板１８には、それぞれ連動用係合軸１６及びガイドピン１７に対応して、上下方向に長い長孔１９と、上下方向の長孔及び円弧孔を連設した全体の形状が略くの字形の逃げ孔２１とが開口している（図２参照）。   A stepped engagement plate 18 is mounted on the portion of the interlocking rod 2 facing the interlocking engagement shaft 16 and the guide pin 17, and the interlocking engagement shaft 16 and the guide pin are respectively attached to the engagement plate 18. Corresponding to FIG. 17, a long hole 19 that is long in the vertical direction and a generally U-shaped escape hole 21 that is formed by connecting a long hole and an arc hole in the vertical direction are opened (see FIG. 2). .

そして、上記連動用係合軸１６は長孔１９と、ガイドピン１７は逃げ孔２１とそれぞれ摺動可能に係合している。   The interlocking engagement shaft 16 and the guide pin 17 are slidably engaged with the long hole 19 and the escape hole 21, respectively.

他方、障子１１の各側端縁上部の前記支持片１３には、図２及び図３に示すように、連動杆２に向けてロックピン２２が突設されており、連動杆２には、障子閉鎖時このロックピン２２と係合して障子１１を窓枠に錠止する係止片２３が装着されている。   On the other hand, as shown in FIGS. 2 and 3, a lock pin 22 projects from the support piece 13 at the upper edge of each side edge of the shoji 11 toward the interlocking rod 2. A locking piece 23 is mounted that engages with the lock pin 22 to lock the shoji 11 to the window frame when the shoji is closed.

図示の実施例における係止片２３は、前記係合板１８に連設された全体の形状が鉤形の板材で、連動杆２および縦枠１に平行な係止端縁２３ａと、この係止端縁２３ａの先端に連設された傾斜端縁２３ｂとを有し（図２）、窓閉鎖状態においては、上記係止端縁２３ａが外側からロックピンと係合する。   The locking piece 23 in the illustrated embodiment is a plate-like plate material that is continuous with the engagement plate 18 and has a locking edge 23 a parallel to the interlocking rod 2 and the vertical frame 1, and this locking plate. In the closed state of the window, the locking end edge 23a engages with the lock pin from the outside.

また、傾斜端縁２３ｂは、ロックピン２２と係止片２３とが係合のため相互に近接するとき、傾斜端縁２３ｂが先ずロックピン２２と当接し、これらの間に作用するくさび作用により、ロックピン２２を窓枠側に押し付ける作用をする。   Further, when the lock pin 22 and the locking piece 23 come close to each other for the engagement, the inclined end edge 23b is first brought into contact with the lock pin 22 due to the wedge action acting between them. The lock pin 22 is pressed against the window frame side.

ちなみに、上記ロックピン２２を連動杆２に、係止片２３をルーバーの側端縁に配設してもよいことは言うまでもない。   Incidentally, it goes without saying that the lock pin 22 may be disposed on the interlocking rod 2 and the locking piece 23 may be disposed on the side edge of the louver.

また、前記連動用係合軸１６の長孔１９における上下方向の遊動量は、ロックピン２２及び係止片２３の係脱に要する相互移動量と同程度に設定するものとする。   The amount of vertical movement in the long hole 19 of the interlocking engagement shaft 16 is set to be approximately the same as the amount of mutual movement required to engage and disengage the lock pin 22 and the locking piece 23.

上記のように構成された本発明の一実施例による開閉金具は、障子の閉鎖時には、図４に示すように、連動用係合軸１６が長孔１９の下端に定座している。   In the opening / closing bracket according to the embodiment of the present invention configured as described above, the interlocking engagement shaft 16 is seated on the lower end of the long hole 19 as shown in FIG.

窓を開けるため操作ハンドルを所定の方向に回すと、連動杆２は下降を始め、不動のロックピン２２に対し相対的に係止片２３が下降するので、これらの係合が解け始めるが、これらが係合している間は連動用係合軸１６は長孔１９中で遊動しているので障子１１には連動杆２からの操作力は作用しない（図４参照）。   When the operation handle is turned in a predetermined direction to open the window, the interlocking rod 2 starts to descend and the locking piece 23 descends relative to the stationary lock pin 22, so that the engagement begins to be released. While these are engaged, the interlocking engagement shaft 16 is floating in the long hole 19, so that the operating force from the interlocking rod 2 does not act on the shoji 11 (see FIG. 4).

ロックピン２２と係止片２３との係合が完全に解けると（図５参照）、連動用係合軸１６が長孔１９の上端に到達し、以降連動杆２がさらに下降すると、図１及び図６に示すように、障子１１に揺動軸１４回り時計方向のモーメントが作用し障子１１が開く。このモーメントは図示しないもう一方の縦枠側からも作用することは言うまでもない。   When the engagement between the lock pin 22 and the locking piece 23 is completely released (see FIG. 5), the interlocking engagement shaft 16 reaches the upper end of the long hole 19, and the interlocking rod 2 is further lowered thereafter. And as shown in FIG. 6, the moment of clockwise rotation of the swing axis 14 acts on the shoji 11, and the shoji 11 opens. It goes without saying that this moment also acts from the other vertical frame side (not shown).

障子を閉めるため操作ハンドルを逆方向に回すと、各部材は図６図示の状態から、図１、及び図５に示す状態を経て、図４に示す状態になることは前記したとおりである。   As described above, when the operation handle is rotated in the reverse direction to close the shoji, each member changes from the state shown in FIG. 6 to the state shown in FIG. 4 through the state shown in FIGS. 1 and 5.

なお、特に障子を閉めるとき、障子１１には自重によって常時開放方向に回動するモーメントが作用しており、このモーメントは揺動軸１４（図１参照）の回りで反時計方向に作用する。   In particular, when closing the shoji, a moment that always rotates in the opening direction due to its own weight acts on the shoji 11, and this moment acts counterclockwise around the swing shaft 14 (see FIG. 1).

本発明においては、障子１１を揺動軸１４を中心とする挺子と看做した場合、力点である連動用係合軸１６と揺動軸１４との距離が大きいので、障子を閉めるときでもその作用力を小さくし、開閉操作を円滑にすることは前記した通りである。   In the present invention, when the shoji 11 is regarded as an insulator having the swinging shaft 14 as the center, the distance between the interlocking engagement shaft 16 and the swinging shaft 14 as a power point is large, so even when closing the shoji. As described above, the acting force is reduced to facilitate the opening and closing operation.

また、障子１１の回動軸である揺動軸１４は、縦枠に直接固定されておらず、支持レバー１５を介して間接的に、かつ揺動可能に縦枠１に支持されている。   Further, the swing shaft 14 that is the pivot shaft of the shoji 11 is not directly fixed to the vertical frame, but is supported by the vertical frame 1 via the support lever 15 so as to be swingable indirectly.

それは、連動用係合軸１６を介して相互に係合する障子１１の側端縁と連動杆２とが、前者が揺動軸１４回りの回動をするのに対し後者が上下方向の直線動をするため、一方を自由にしておかないと両者の係合部にこじりが生じるからである。   That is, the side edge of the shoji 11 that engages with each other via the interlocking engagement shaft 16 and the interlocking rod 2 rotate around the swing shaft 14 while the latter is a straight line in the vertical direction. This is because if the one side is not free for movement, the engagement portion between the two will be twisted.
