に挿入し、その先の部分を折り曲げる構造の照明器具用
ルーバは公知である。A plurality of louver pieces and a louver frame for mounting them,
Forming insertion tongues at both ends of each louver piece, forming a plurality of tongue insertion square holes in the louver frame for receiving each insertion tongue, and corresponding each insertion tongue A louver for a lighting fixture having a structure in which it is inserted into a square hole for inserting a tongue portion and a tip portion thereof is bent is known.
上記従来のものは、各差込舌部をその付け根付近から折
り曲げる構造である。このため、その折り曲げ位置ある
いは折り曲げ角度のバラツキにより、ルーバ片が堅固に
固定されず、がたつく心配がある。The above-mentioned conventional structure has a structure in which each insertion tongue is bent from the vicinity of its root. Therefore, the louver piece may not be firmly fixed due to variations in the bending position or the bending angle, which may cause rattling.
本考案はルーバ枠に各ルーバ片を堅固定に固定すること
を目的とする。The present invention aims to firmly fix each louver piece to the louver frame.
本考案においては、ルーバ片側の各差込舌部の付け根付
近に、当該差込舌片部を受入れる舌部差込用角孔の縁と
斜めに交差する変形角孔を形成する。In the present invention, a deformed square hole is formed near the base of each insert tongue on one side of the louver and diagonally intersects the edge of the square hole for inserting the tongue to receive the insert tongue.
また差込舌部を、変形角孔の縁の途中が舌部差込用角孔
の縁に圧接し、かつ変形角孔の縁の一部が舌部差込用角
孔の縁を乗り越えるように変形させる。Also, in the insertion tongue, the middle of the edge of the deformation square hole should be pressed against the edge of the tongue insertion square hole, and a part of the edge of the deformation square hole should cross over the edge of the tongue insertion square hole. Transform into.
ルーバ片側の差込舌部をルーバ枠側の舌部差込用角孔に
差込む。この状態では差込舌部の付け根付近に形成され
た変形角孔は当該差込舌部を受入れる舌部差込用角孔の
縁と斜めに交差する。Insert the tongue on one side of the louver into the square hole for inserting the tongue on the louver frame side. In this state, the deformed rectangular hole formed near the base of the insertion tongue obliquely intersects the edge of the tongue insertion square hole that receives the insertion tongue.
その後に差込舌部を変形させる。差込舌部の付け根付近
に形成された変形角孔はこの変形を容易にする。After that, the insertion tongue is deformed. A deformed square hole formed near the base of the insertion tongue facilitates this deformation.
変形にともなって、変形角孔の縁(差込舌部側の縁)の
途中が舌部差込用角孔の縁に圧接する。変形角孔の縁の
一部は舌部差込用角孔の内側に没した状態を保が、縁の
残りは舌部差込用角孔の縁を乗り越える。Along with the deformation, the edge of the deformed square hole (edge on the insertion tongue side) is pressed against the edge of the square hole for inserting the tongue. A part of the edge of the deformed square hole remains depressed inside the square hole for inserting the tongue, while the rest of the edge rides over the edge of the square hole for inserting the tongue.
前記圧接にともなう力はルーバ片を舌部差込用角孔から
引き出すように作用する。このため、カバー片の両端部
はルーバ枠に堅固に固定される。The force associated with the pressure contact acts to pull out the louver piece from the square hole for inserting the tongue portion. Therefore, both ends of the cover piece are firmly fixed to the louver frame.

角孔4はその全体が舌部差込用角孔5から抜け出しても
いけないし、その全体が舌部差込用角孔5に没していて
もいけない。Insert each insertion tongue 3 into the corresponding tongue insertion square hole 5.
A deformed square hole 4 that obliquely intersects the edge of the tongue inserting square hole 5 is formed near the base of each inserting tongue 3. The deformed square hole 4 has a V shape. The central portion 41 of the V-shape passes through the tongue-inserting square hole 5, and the both ends 42 of the V-shape bury the tongue-inserting square hole 5. The middle thereof intersects the edge of the tongue insertion square hole 5. The entire deformed square hole 4 must not be pulled out from the tongue insertion square hole 5, and the entire deformed square hole 4 should not be immersed in the tongue insertion square hole 5.

く字形は差込舌部3の変形を示す。ちなみに、第4図の
く字形は変形角孔4の形状を示す。The insertion tongue 3 is pressed against the edge of the tongue insertion square hole 5 at the middle of the edge of the deformation square hole 4, and a part of the edge of the deformation square hole 4 of the tongue insertion square hole 5 is pressed. Transform it to get over the edge. This deformation work is performed after inserting the insertion tongue 3 into the tongue insertion square hole 5. It is the portion outside the deformed square hole 4 that is deformed, and that portion bends in a V shape as shown in FIG. The V-shape in FIG. 3 shows the deformation of the insert tongue 3. Incidentally, the V-shape in FIG. 4 shows the shape of the deformed square hole 4.
差込舌部3を変形させる作業は挟み面がく字形を呈する
特殊な挟み工具を使い、それで差込舌部3を強く挟んで

箇所ある。変形角孔4の縁の一部(圧接触箇所100と100
の間の部分)は舌部差込用角孔5の縁を乗り越える。The work of deforming the insert tongue 3 is performed by using a special sandwiching tool having a sandwiching surface having a dogleg shape, and firmly sandwiching the insert tongue 3 with it. Along with the deformation, the edge of the deformed square hole 4 (however, the edge on the side of the insertion tongue 3) comes into pressure contact with the edge of the square hole 5 for inserting the tongue. Reference numeral 100 in FIG. 3 represents a pressure welding point. 2 pressure contact points
There are places. Part of the edge of the deformed square hole 4 (pressure contact points 100 and 100
The portion between the two) gets over the edge of the tongue insertion square hole 5.

角孔4の伴う各ルーバ片1は舌部差込用角孔5を伴うル
ーバ枠7に対して堅固に固定される。The V-shaped deformed square hole 4 limits the deformed portion of the insertion tongue 3 and facilitates the deformation. Further, since the deformed square hole 4 obliquely intersects the edge of the tongue-inserting square hole 5, when the insert tongue portion 3 is deformed, somewhere on the edge of the deformable square hole 4 is used to insert the tongue part. Pressure contact with the edge of the square hole 5 without looseness. Therefore, each louver piece 1 having the insertion tongue 3 and the deformed square hole 4 is firmly fixed to the louver frame 7 having the tongue insertion square hole 5.
