【考案の詳細な説明】本考案はルーバー窓開閉装置に関するものであ
る。[Detailed Description of the Invention] The present invention relates to a louver window opening/closing device.

この種ルーバー窓開閉装置としては実公昭48−

ことができる提案は既になされている。 This type of louver window opening/closing device was first introduced in 1973.
As in No. 28744, a helical worm wheel 3 is supported in a container frame 1 (number of the above-mentioned publication), and a worm 5 rotated by a handle is housed in a cylindrical body that projects obliquely from the container frame 1. Proposals have already been made that by doing so, a small opening/closing device can be provided without being obstructed by the window frame or mounting frame.

しかし、この公知技術では、ケースの軸方向と
ハンドルシヤフトの交叉する角度が一定であり、
たとえば30度でいちど製作すると取付現場でハン
ドルが壁にあたるため45度の角度のものが欲しい
場合、あらためてケース本体から型をのこさねば
ならない不都合があつた。 However, in this known technology, the angle at which the axial direction of the case and the handle shaft intersect is constant;
For example, if you make a handle at a 30-degree angle, the handle will hit the wall at the installation site, so if you wanted a 45-degree angle, you would have to leave the mold out of the case body.

一挙に解決することを目的とする。 In this invention, the case body is all factory-installed inside the sash, and it is possible to select any handle assembly for 30 degrees, 45 degrees, or 60 degrees depending on the situation at the installation site. The aim is to secure design freedom, improve productivity, and reduce costs all at once.

る。 In other words, the device of the present invention has a decorative tube 7 on the indoor side,
A case 1 is provided on the outside of the room, the joint 8 of the handle 9 is housed in the decorative tube 7, and the worm 4 and the worm wheel 2 perpendicular to the worm 4 are housed in the case 1, so that the manufacturing cost is not increased and the interior space is reduced. It is an object of the present invention to provide a louver window opening/closing device with a small inwardly protruding part and a handle that can be easily rotated.

すことができる。(Explanation of operation) When closing the louver 14 In the open state of the louver 14 in Fig. 2,
When the handle 9 is turned in the direction of arrow _a1 , the worm 4 rotates, and the worm wheel 2 is rotated in the direction of arrow _a2 . Then, since the arm 11 pushes up the support shaft 13a of the push rod 13, the continuous rod 12 is pushed up. Thus,
The louver 14 is rotated and closed as shown in FIG. At this time, when the worm 2 rotates, the coil spring 3 is wound up. That is, the pin 2' rotates in the direction of the arrow _a2 .
At this time, the louver 14 rotates in the direction of arrow _a3 about the louver rotation shaft 15, and the worm wheel 3 is urged in the direction of arrow _a2 by the weight of the louver 14.
Therefore, when the handle 9 is turned in the direction of arrow _a1 , it can be turned with an appropriate force that is contrary to the force of the coil spring 3.

開く。 When opening the louver 14 To open the louver 14 from the closed state shown in FIG. 3 to the state shown in FIG. 2, first rotate the handle 9 in the direction opposite to the arrow _a1 . Then, the worm 2 rotates in the direction of arrow _b2 , and the louver 14 rotates in the direction of arrow _b3 to open.

As it rotates, it is rewound against the weight of the connecting rod 12 and the louver 14.

（本考案の作用効果）実公昭48−28744号のようにケースとハンド
ルシヤフトの角度が一定でないので適宜ハンド
ル・シヤフトの交叉角をかえたものを用意して
おくと、たとえば取付現場ですぐ近くに壁が立
ち上つているような場合、30度の交叉角のハン
ドルで手が壁にあたる場合45度のハンドルを使
用すればよく、ハンドルだけの在庫で対応でき
る。(Effects of the present invention) As shown in Utility Model Publication No. 48-28744, the angle between the case and the handle shaft is not constant, so if you prepare one with the intersection angle of the handle and shaft changed as appropriate, it will be possible to easily install it at the installation site, for example. If there is a wall rising up above the wall, you can use a 45-degree handle if your hand hits the wall with a 30-degree cross-angle handle, and you can handle this with just the handle in stock.

又、最近は、サツシがカラー化しているが、
ケース本体と分離できるので、ケース本体はサ
ツシのカラーに関係なく１種類だけを工場付け
で流通させハンドルのみをいろいろのカラーの
ものを要望に応じて納品すればよく、きわめて
経済的である。 Also, recently, Satsushi has become colored,
Since it can be separated from the case body, only one type of case body can be distributed at the factory regardless of the color of the sash, and handles in various colors can be delivered as requested, making it extremely economical.

ケース１を窓枠サツシＳの室外側に取付け、
開閉装置の一部を室外側空間を利用したので、
その分だけ室内外への装置の突出部分が少なく
なり、室内操作部の邪魔にならない。 Attach case 1 to the outdoor side of window frame satsushi S,
Because part of the opening/closing device was made use of the outdoor space,
The protruding portion of the device indoors and outdoors is correspondingly reduced, so it does not interfere with the indoor operating section.

ケース１をサツシＳに予め工場で固定してお
けば、現場では化粧筒７のみを取り付ければよ
い。したがつてはす歯ウオームホイールを用い
る必要がないのにかかわらず、実公昭48−
28744号に比べて現場での取付作業が煩雑にな
らない。 If the case 1 is fixed to the sash S in advance at the factory, only the decorative tube 7 needs to be attached at the site. Therefore, although there is no need to use a helical worm wheel,
Installation work on site is less complicated than No. 28744.
