５はのこ刃４の下側にのこ刃面と交差する様に設けられ
た定盤である。5 is a surface plate provided below the saw blade 4 so as to intersect with the saw blade surface.
６は前記のこ刃４の上部から定盤５の上部近傍捷でを被
覆したのこ刃カバーである。Reference numeral 6 denotes a saw blade cover that covers the upper part of the saw blade 4 and the upper part of the surface plate 5.
のこ刃カバー６はのこ刃４と平行な平面によって中央か
ら二体６Ａ、６Ｂに分割形成され、本体側部分６Ａは本
体１に固着されている。The saw blade cover 6 is divided into two parts 6A and 6B from the center by a plane parallel to the saw blade 4, and the main body side part 6A is fixed to the main body 1.
のこ刃カバー６の他の一体６Ｂは端部を前記定盤５の一
端に回動自在に軸支され、上縁部においてネジ７で前記
のと刃カバー６Ａに着脱可能に固着されている。The other integral part 6B of the saw blade cover 6 has its end rotatably supported by one end of the surface plate 5, and is removably fixed to the saw blade cover 6A with a screw 7 at its upper edge. .
８はのこ刃４の下部から中心部までを覆ったほぼ扇形の
安全カバーである。Reference numeral 8 denotes a substantially fan-shaped safety cover that covers the saw blade 4 from the bottom to the center.
安全カバー８は前記のこ刃カバー６Ｂの前記のこ刃４の
中心と対応する位置にネジ９によシ回動自在に軸支され
ている。The safety cover 8 is rotatably supported by a screw 9 at a position corresponding to the center of the saw blade 4 of the saw blade cover 6B.
１０は安全カバー８の前記軸支部分に装着されたうす巻
きバネであって一端を安全カバー８に係止し、他端をの
こ刃カバー６Ｂに係止するとともに安全カバー８を常に
は第３図で反時計方向へ付勢している。Reference numeral 10 denotes a thinly coiled spring attached to the pivot portion of the safety cover 8. One end of the spring is fixed to the safety cover 8, and the other end is fixed to the saw blade cover 6B. In Figure 3, the force is applied counterclockwise.
１１は前記のこ刃カバー６Ｂの下部に側方へ突出して設
けられた、安全カバー８を定装置に止めるためのストッ
パである。Reference numeral 11 denotes a stopper for stopping the safety cover 8 in a fixed position, which is provided at the lower part of the saw blade cover 6B so as to protrude laterally.
上記の構成に釦いて非切削状態ではのこ刃４が殆んど被
覆されている。With the above configuration, most of the saw blade 4 is covered in the non-cutting state.
この状態でのこ刃４を着脱するにはネジ７を外し、安全
カバー８をのこ刃カバー６Ｂ内に押し込み、のこ刃カバ
ー６Ｂを回動させてのこ刃４を露出させる。To attach or detach the saw blade 4 in this state, remove the screw 7, push the safety cover 8 into the saw blade cover 6B, and rotate the saw blade cover 6B to expose the saw blade 4.
その後、のこ刃４をスピンドル３から外してのこ刃カバ
ー６Ａの側方から取シ出す。Thereafter, the saw blade 4 is removed from the spindle 3 and taken out from the side of the saw blade cover 6A.
本考案は上記の様にのこ刃カバー６をのこ刃４と平行な
平面によって中央から６Ａ 、６Ｂの二体に分割形成し
、６Ａを本体１側に固着し、６Ｂの一端を回動自在に軸
支した構成であるから、十分な連間防音効果を有すると
同時にのこ刃４の着脱が容易な防音カバーを得る事がで
きる。In the present invention, as described above, the saw blade cover 6 is divided into two parts 6A and 6B from the center by a plane parallel to the saw blade 4, 6A is fixed to the main body 1 side, and one end of 6B is rotated. Since it is configured to be freely pivoted, it is possible to obtain a soundproof cover that has sufficient continuous soundproofing effect and at the same time allows the saw blade 4 to be easily attached and detached.
