[0016] このストレートサンダ 10は、以上のようになっており、頭部ハウジング 23が研磨作用 部 3側に押圧されると、図 11に示すように皿ばね 268がつば部 251とベース本体 26 1との間で圧縮され、頭部ハウジング 23、連結部材 25、駆動軸 4、バランサ 7および 駆動伝達軸 8が、研磨作用部 3側に押し込まれて、係止爪 252の係合溝 242への係 合が解除される。つぎに、この押し込み状態を保持した状態で、頭部ハウジング 23を 回転させれば、把手部 22が駆動軸 4周りに回転する。そして、把手部 22を所望位置 まで回転させて、押圧を解除すれば、皿ばね 268の付勢力で頭部ハウジング 23、連 結部材 25、駆動軸 4、ノランサ 7および駆動伝達軸 8が元の位置まで戻るとともに、 係止爪 252が係合溝 242に係合されて、把手部 22が回転した所望位置で固定され る。 [0016] The straight sander 10 is configured as described above. When the head housing 23 is pressed toward the polishing action part 3, the disc spring 268 has a flange part 251 and a base body 26 as shown in FIG. 1, the head housing 23, the connecting member 25, the drive shaft 4, the balancer 7, and the drive transmission shaft 8 are pushed into the polishing action portion 3 side to the engagement groove 242 of the locking claw 252. Will be released. Next, if the head housing 23 is rotated in a state where the pushed-in state is maintained, the grip portion 22 rotates around the drive shaft 4. Then, when the handle 22 is rotated to a desired position and the pressure is released, the head housing 23, the connecting member 25, the drive shaft 4, the nolancer 7 and the drive transmission shaft 8 are restored to the original by the biasing force of the disc spring 268. While returning to the position, the engaging claw 252 is engaged with the engaging groove 242 and the handle 22 is fixed at the desired rotated position.
[0017] すなわち、このストレートサンダ 10によれば、把手部 22が駆動軸 4の周りを回転自 在となっているので、把手部 22の回転により、自由に把手部 22を作業しやすい位置 に固定することができる。したがって、作業者が無理な姿勢をとつたりしなくても、研磨 作業を行うことができ、作業性がよくなる。 That is, according to the straight sander 10, the handle portion 22 is rotated around the drive shaft 4, so that the handle portion 22 can be freely moved by the rotation of the handle portion 22. Can be fixed. Therefore, even if the operator does not take an unreasonable posture, the polishing work can be performed, and workability is improved.
[0018] しかしながら、このストレートサンダ 10の場合、係止爪 252と係合溝 242との係合を
一旦解除させて力も把手部 22を駆動軸 4周りに回転させる構造になっているが、係 止爪 252と係合溝 242との係合の解除にあたっては、頭部ハウジング 23、連結部材 25、駆動軸 4、バランサ 7および駆動伝達軸 8を研磨作用部 3側に押し込まねばなら ない。したがって、駆動伝達軸 8や、この駆動伝達軸 8に枢支されたリンク部材 81に 不必要な力が加わり、駆動伝達軸 8を回転自在に支持している軸受け 72やリンク部 材 8などが早期に損傷する原因になったり、駆動軸 4の回転バランスが崩れて駆動の 際に大きな振動が生じる原因となることがわ力 た。 [0018] However, in the case of this straight sander 10, the engagement between the locking claw 252 and the engagement groove 242 is not achieved. The structure is such that once the force is released and the handle 22 is rotated around the drive shaft 4, the head claw 252 and the connecting member 25, The drive shaft 4, balancer 7 and drive transmission shaft 8 must be pushed into the polishing section 3 side. Therefore, an unnecessary force is applied to the drive transmission shaft 8 and the link member 81 pivotally supported by the drive transmission shaft 8, and the bearing 72 and the link member 8 that rotatably support the drive transmission shaft 8 are provided. It was found that this could cause damage early, or cause the vibration of the drive shaft 4 to lose its rotational balance and cause significant vibration during driving.

[0031] スチールボール保持板 9の上には付勢力伝達部材 94が設けられて 、る。 An urging force transmission member 94 is provided on the steel ball holding plate 9.
ロックアジャストハウジング 24aは、上端に頭部ハウジング 23aの外径と略同じか少 し大きい径の頭部ハウジング揷通孔 243を有し、下端にフランジ部 241を備えていて The lock adjustment housing 24a has a head housing through hole 243 having a diameter substantially equal to or slightly larger than the outer diameter of the head housing 23a at the upper end, and a flange portion 241 at the lower end.
、頭部ハウジング 23aの外径より大き 、筒状をして 、る。 The cylindrical shape is larger than the outer diameter of the head housing 23a.
[0032] 頭部ハウジング揷通孔 243は、その内周面に頭部ハウジング 23aとの間を気密にシ ールする Oリング 245が嵌着されて!、る。 [0032] The head housing through hole 243 is fitted with an O-ring 245 that hermetically seals between the head housing 23a and the head housing 23a.
フランジ部 241は、小ねじ 244によってベース 26の上面に固定されているとともに、 その下面にスチールボール保持板 9の係止凸部 92が嵌まり込む 2つの支持板係止 凹部 246が中心を挟んで対称に穿設されている。 The flange portion 241 is fixed to the upper surface of the base 26 by a machine screw 244, and the two support plate locking recesses 246 sandwich the center between the locking protrusion 92 of the steel ball holding plate 9 and the lower surface thereof. It is drilled symmetrically.
[0033] そして、ロックアジャストハウジング 24aは、リング状の付勢力伝達部材 94を介してス チールボール 93をつば部 251側に付勢するコイルスプリング S 1を頭部ハウジング 2[0033] Then, the lock adjust housing 24a is provided with a coil spring S1 for biasing the steel ball 93 toward the collar portion 251 via the ring-shaped biasing force transmitting member 94.
3aの下端部との隙間に内蔵するとともに、係合凸部 92を支持板係止凹部 246に係 合させた状態で小ねじ 244によってベース 26の上面に固定されている。 It is incorporated in the gap with the lower end of 3a, and is fixed to the upper surface of the base 26 by a machine screw 244 in a state where the engaging convex portion 92 is engaged with the support plate engaging concave portion 246.
[0034] このストレートサンダ laは、以上のように、スチーノレボーノレ 93が、コィノレスプリング S[0034] As described above, this straight sander la has Steino Lebonore 93, Coinole Spring S
1の付勢力によってつば部 251側に常に付勢されている。したがって、押圧されたス チールボール 93の一部がつば部 251の位置決め凹部 253内に入り込み、頭部ハウ ジング 23aおよび把手部 22の駆動軸 4周りの回転が抑止される。 It is always urged toward the collar 251 by the urging force of 1. Accordingly, a part of the pressed steel ball 93 enters the positioning recess 253 of the collar portion 251 and rotation of the head housing 23a and the handle portion 22 around the drive shaft 4 is suppressed.
なお、コイルスプリング S1は、研磨作業時に把手部に加わると予想される駆動軸 4 周りの回転力以下ではスチールボール 93の位置決め凹部 253内への係合が解除さ れな ヽ付勢力に調整されて!、る。
[0035] 一方、把手部 22を手で持ち、コイルスプリング S1の付勢力以上の力で駆動軸 4の 周りを回転させようとすると、スチールボール 93が付勢力伝達部材 94を介してコイル スプリング S1を頭部ハウジング 23a側へ収縮させながらつば部 251の隣り合った 2つ の位置決め凹部 253の間のつば部 251の上面に乗り上げ、位置決めが解除される。 そして、たとえば、図 4 (a)に示すように、把手部 22の軸が研磨作用部 3の長手方向 に一致した位置から、図 4 (b)に示すように、把手部 22の軸が研磨作用部 3の長手方 向から 30° 回転した位置、図 4 (c)に示すように、把手部 22の軸が研磨作用部 3の 長手方向から 60° 回転した位置など、 15° 単位で所定位置まで把手部 22を回転さ せれば、スチールボール 93がコイルスプリング S1の付勢力によって、対応する位置 決め凹部 253に再び入り込み、把手部 22を回転抑止するようになって 、る。 The coil spring S1 is adjusted to a biasing force that does not release the engagement of the steel ball 93 into the positioning recess 253 below the rotational force around the drive shaft 4 that is expected to be applied to the handle during polishing. Te! [0035] On the other hand, when the handle portion 22 is held by hand and an attempt is made to rotate around the drive shaft 4 with a force greater than the urging force of the coil spring S1, the steel ball 93 passes through the urging force transmission member 94 to the coil spring S1. Is retracted to the head housing 23a side and rides on the upper surface of the flange portion 251 between the two positioning recesses 253 adjacent to the flange portion 251, and the positioning is released. Then, for example, as shown in FIG. 4 (a), from the position where the shaft of the handle portion 22 coincides with the longitudinal direction of the polishing action portion 3, the shaft of the handle portion 22 is polished as shown in FIG. 4 (b). Predetermined in units of 15 °, such as a position rotated 30 ° from the longitudinal direction of the action part 3 and a position where the shaft of the handle part 22 is rotated 60 ° from the longitudinal direction of the polishing action part 3 as shown in FIG. 4 (c). When the handle portion 22 is rotated to the position, the steel ball 93 enters the corresponding positioning recess 253 again by the biasing force of the coil spring S1, and the handle portion 22 is prevented from rotating.
[0036] 以上のように、このストレートサンダ laによれば、把手部 22が駆動軸 4周りに回転自 在となっているので、把手部 22の回転により、自由に把手部 22を作業しやすい位置 にすることができる。し力も、コイルスプリング S1によって付勢されたスチールボール 9 3と、位置決め凹部 253とからなる把手部回転抑止構造を設けたので、把手部 22の 回転停止位置でコイルスプリング S1によって付勢されたスチールボール 93が位置決 め凹部 253に入り込んで把手部 22を位置決めするとともに、研磨作業時に把手部 2 2に加わると予想される駆動軸 4周りの回転力以下では、スチールボール 93が位置 決め凹部 253に入り込んだ状態を維持し、把手部 22の回転を抑止することができる 。すなわち、把手部 22が、研磨作業中に駆動軸 4周りに回転することがなぐ作業者 が無理な姿勢をとつたりしなくても、研磨作業を行うことができ、また、一旦、決めた把 手部 22の軸と研磨作用部 3の長手方向との角度が研磨作業中にも維持することがで き作業性がよくなる。 [0036] As described above, according to this straight sander la, the handle portion 22 is self-rotating around the drive shaft 4. Therefore, the handle portion 22 can be freely operated by the rotation of the handle portion 22. Can be in position. Since the grip part rotation restraining structure is provided with the steel ball 93 biased by the coil spring S1 and the positioning recess 253, the steel biased by the coil spring S1 at the rotation stop position of the grip part 22 is also provided. The ball 93 enters the positioning recess 253 to position the handle 22, and the steel ball 93 is positioned to the positioning recess 253 below the rotational force around the drive shaft 4 that is expected to be applied to the handle 22 during polishing. It is possible to prevent the rotation of the grip portion 22 while maintaining the intrusion state. In other words, the polishing operation can be performed even if the gripper 22 does not rotate around the drive shaft 4 during the polishing operation without taking an unreasonable posture. The angle between the shaft of the grip portion 22 and the longitudinal direction of the polishing action portion 3 can be maintained even during the polishing operation, so that the workability is improved.
[0037] また、頭部ハウジング 23aとロックアジャストハウジング 24aとの間のコイルスプリング S1が伸縮するだけであるので、把手部 22を回転させる際に、把手部 22と研磨作用 部 3との駆動軸 4方向の距離を常に一定状態に保つことができる。したがって、把手 部 22を駆動軸 4周りに回転させても駆動伝達軸 8やこれに枢支されたリンク部材 81 にバランスを崩したり歪みを生じさせるような不必要な力がまったく加わらない。した がって、振動が少なく安定した研磨作業を長期間持続させることができる。
[0038] 図 5は、本発明に力かる手持ち研磨装置であるストレートサンダの第 2の実施の形 態をあらわしている。 [0037] Further, since the coil spring S1 between the head housing 23a and the lock adjustment housing 24a only expands and contracts, when the handle portion 22 is rotated, the drive shaft of the handle portion 22 and the polishing action portion 3 is driven. The distance in the four directions can always be kept constant. Therefore, even if the handle portion 22 is rotated around the drive shaft 4, no unnecessary force is applied to the drive transmission shaft 8 or the link member 81 pivotally supported on the drive transmission shaft 8 or the balance member 81 is distorted. Therefore, a stable polishing operation with less vibration can be maintained for a long time. FIG. 5 shows a second embodiment of a straight sander that is a hand-held polishing apparatus that is useful in the present invention.
図 5に示すように、このストレートサンダ lbは、連結部材 25bのつば部 251の上面が 平坦で、頭部ハウジング 23bの下端外周面の同じ高さに 24個の位置決め凹部 231 ( 図 5では 2つしかあらわれて 、な 、)が等ピッチに設けられ、位置決め凹部 231と同じ 高さ位置でロックアジャストハウジング 24bの内周面に 6個のスプリング支持穴 247が 等ピッチで穿設されている。そして、各スプリング支持穴 247に先端にスチールボー ル 93を備えたスプリング S2が嵌装され、スプリング S2の付勢力によってスチールボ ール 93の一部が位置決め凹部 231に入り込むようになった、スプリング S2によって 付勢されたスチールボール 93と、位置決め凹部 231とからなる把手部回転抑止構造 とした以外は、上記ストレートサンダ laと同様になつている。 As shown in Fig. 5, this straight sander lb has a flat upper surface of the flange portion 251 of the connecting member 25b and 24 positioning recesses 231 (2 in Fig. 5) at the same height of the outer peripheral surface of the lower end of the head housing 23b. In this example, six spring support holes 247 are formed at equal pitches on the inner peripheral surface of the lock adjustment housing 24b at the same height as the positioning recess 231. Then, each spring support hole 247 is fitted with a spring S2 having a steel ball 93 at the tip, and a part of the steel ball 93 enters the positioning recess 231 by the urging force of the spring S2. It is the same as the straight sander la described above except that it has a grip portion rotation restraining structure comprising a steel ball 93 urged by and a positioning recess 231.
[0039] 図 6は、本発明に力かる手持ち研磨装置であるストレートサンダの第 3の実施の形 態をあらわしている。 [0039] Fig. 6 shows a third embodiment of a straight sander which is a hand-held polishing apparatus useful for the present invention.
図 6に示すように、このストレートサンダ lcは、コイルスプリング S1によって付勢され たスチールボール 93と、位置決め凹部 253とからなる把手部回転抑止構造に代えて 、コイルスプリング S 1の付勢力によって付勢された上側鋸刃部 951と、下側鋸刃部 2 56とを有する把手部回転抑止構造とした以外は、上記ストレートサンダ laと同様にな つている。 As shown in FIG. 6, this straight sander lc is urged by the urging force of the coil spring S 1 instead of the grip portion rotation restraining structure comprising the steel ball 93 urged by the coil spring S1 and the positioning recess 253. The straight sander la is the same as that of the straight sander la except that the handle portion rotation restraining structure having the biased upper saw blade portion 951 and the lower saw blade portion 256 is employed.
すなわち、このストレートサンダ lcは、連結部材 25cの上面に位置決め凹部 253に 代えて、同形状の 2等辺三角形をした係合凸部 256aが円筒の上端全周にわたって 連続的に鋸刃状に並ぶ下側鋸刃部 256が形成され、付勢力伝達部材 95の下面に 下側鋸刃部 256の隣り合った 2つの係合凸部 256aの間にかみ合う係合凸部 952が 連続的に鋸刃状に並ぶ上側鋸刃部 951が形成されている。 That is, in this straight sander lc, instead of the positioning recess 253 on the upper surface of the connecting member 25c, an engagement protrusion 256a having the same shape of an isosceles triangle is continuously arranged in a saw-tooth shape over the entire upper end of the cylinder. A side saw blade portion 256 is formed, and an engaging convex portion 952 that meshes between two adjacent engaging convex portions 256a of the lower saw blade portion 256 on the lower surface of the urging force transmission member 95 is a continuous saw blade shape. The upper saw blade portion 951 is formed in a row.
[0040] そして、このストレートサンダ lcは、コイルスプリング S1の付勢力によって、付勢力 伝達部材 95の各係合凸部 952が下側鋸刃部 256の隣り合った 2つの係合凸部 256 aの間にかみ合い、把手部 22の回転が抑止される。さらに、把手部 22を手で持って 駆動軸 4周りに回転力を加えると、係合凸部 256aと係合凸部 952の回転方向に相 対する側壁のテーパによってコイルスプリング S1の付勢力に抗して上側鋸刃部 951
の各係合凸部 952が頭部ハウジング 23a側に押し上げられ、各係合凸部 952が係合 凸部 256aを乗り越え、把手部 22が駆動軸 4の周りを回転するようになっている。 [0040] The straight sander lc has two engaging convex portions 256a in which each engaging convex portion 952 of the urging force transmitting member 95 is adjacent to the lower saw blade portion 256 by the urging force of the coil spring S1. And the handle 22 is prevented from rotating. Further, when the handle portion 22 is held by hand and a rotational force is applied around the drive shaft 4, the biasing force of the coil spring S1 is resisted by the taper of the side wall relative to the rotational direction of the engaging convex portion 256a and the engaging convex portion 952. The upper saw blade 951 The engaging projections 952 are pushed up toward the head housing 23a, the engaging projections 952 get over the engaging projections 256a, and the handle 22 rotates around the drive shaft 4.
[0041] 図 7は、本発明に力かる手持ち研磨装置であるストレートサンダの第 4の実施の形 態をあらわしている。 [0041] Fig. 7 shows a fourth embodiment of a straight sander which is a hand-held polishing apparatus useful for the present invention.
図 7に示すように、このストレートサンダ Idは、コイルスプリング S1によって付勢され たスチールボール 93と、位置決め凹部 253とからなる把手部回転抑止構造に代えて 、コイルスプリング S1によって付勢された摩擦抵抗材 961からなる把手部回転抑止 構造を備えて 、る以外は、上記ストレートサンダ laと同様になつて 、る。 As shown in FIG. 7, this straight sander Id is a frictional force urged by the coil spring S1 in place of a grip portion rotation restraining structure comprising a steel ball 93 urged by the coil spring S1 and a positioning recess 253. The straight sander la has the same structure as the straight sander la except that it has a grip rotation prevention structure made of a resistance material 961.
[0042] すなわち、このストレートサンダ Idは、連結部材 25bのつば部 251の上面が平坦で 、付勢力伝達部材 96の下面にリング状の摩擦抵抗材 961がー体ィ匕されており、摩擦 抵抗材 961がコイルスプリング S1の付勢力によって常につば部 251の上面に圧接さ れているので、摩擦抵抗材 961とつば部 251との間に生じる摩擦抵抗によって、スト レートサンダ Idよる研磨作業時における振動等によって生じる把手部 22に加わる駆 動軸 4周りの回転力程度では、把手部 22および頭部ハウジング 23aの駆動軸 4周り の回転が抑止され、把手部 22を手で持って所望する回転方向へ所定以上の回転力 を加えれば、把手部 22および頭部ハウジング 23aが駆動軸 4の周りを回転するように なっている。 That is, in this straight sander Id, the upper surface of the flange portion 251 of the connecting member 25b is flat, and the ring-shaped frictional resistance material 961 is formed on the lower surface of the urging force transmission member 96. Since the material 961 is always pressed against the upper surface of the flange portion 251 by the urging force of the coil spring S1, the frictional resistance generated between the friction resistance material 961 and the flange portion 251 causes the friction during the polishing operation by the straight sander Id. The rotational force around the drive shaft 4 applied to the handle portion 22 caused by vibration or the like suppresses rotation of the handle portion 22 and the head housing 23a around the drive shaft 4, and the desired rotation with the handle portion 22 held by hand. When a rotational force of a predetermined value or more is applied in the direction, the handle portion 22 and the head housing 23a rotate around the drive shaft 4.
[0043] そして、このストレートサンダ Idは、摩擦抵抗材 961による摩擦抵抗によって回転を 抑止するようにしたので、把手部 22の回転停止位置を無段階で選べ、より作業性が よくなる。 [0043] Since the straight sander Id is prevented from rotating by the frictional resistance of the frictional resistance material 961, the rotation stop position of the grip portion 22 can be selected in a stepless manner, thereby improving the workability.
なお、摩擦抵抗材の材質としては、特に限定されないが、たとえば、一般ゴム材料、 摩擦繊維基材としての金属繊維、有機繊維、カーボンファイバー、ガラス繊維等の無 機繊維をゴムゃ榭脂等の結合剤に混合して得られたモールド品、焼結金属系摩擦 材料等が挙げられる。 The material of the friction resistance material is not particularly limited. For example, a general rubber material, an inorganic fiber such as a metal fiber, an organic fiber, a carbon fiber, a glass fiber or the like as a friction fiber base material is made of rubber, resin, or the like. Examples include molded products obtained by mixing with a binder, sintered metal friction materials, and the like.
[0044] 図 8は、本発明にカゝかる手持ち研磨装置であるストレートサンダの第 5の実施の形 態をあらわしている。 [0044] FIG. 8 shows a fifth embodiment of a straight sander which is a hand-held polishing apparatus according to the present invention.
図 8に示すように、このストレートサンダ leは、コイルスプリング S1に代えて、付勢手 段として圧縮空気を用いた摩擦抵抗材 961からなる把手部回転抑止構造を備えて
V、る以外は、上記ストレートサンダ Idと同様になつて!/、る。 As shown in FIG. 8, this straight sander le has a grip portion rotation restraining structure made of a friction resistance material 961 using compressed air as a biasing means instead of the coil spring S1. Except for V and Ru, follow the same procedure as for Straight Sander Id above!
すなわち、このストレートサンダ leは、頭部ハウジング 23aと、ロックアジャストハウジ ング 24eとの隙間 29にエアーコンプレッサからの圧縮空気を送り込むために、ロック アジャストハウジング 24eの側壁面に、弁 292付きの圧縮空気供給路 291を設けると ともに、連結部材 25bおよびロックアジャストハウジング 24eの付勢力伝達部材 96eの 側面に対面する部分と、頭部ハウジング 23aの連結部材 25bの上端部外壁面に臨 む部分に隙間 29内を気密に保っための Oリング 293、 294、 295力設けられている。 In other words, this straight sander le is used to send compressed air from the air compressor into the gap 29 between the head housing 23a and the lock adjusting housing 24e. The supply path 291 is provided, and a clearance 29 is formed between the portion facing the side surface of the urging force transmitting member 96e of the connecting member 25b and the lock adjusting housing 24e, and the portion facing the outer wall surface of the upper end portion of the connecting member 25b of the head housing 23a. O-rings 293, 294, 295 are provided to keep the inside airtight.
[0045] そして、このストレートサンダ leは、弁 292を開けて圧縮空気供給路 291を介して隙 間 29内に圧縮空気を送り込み、圧縮空気の圧力によって、付勢力伝達部材 96eを 介して摩擦抵抗材 961をつば部 251の上面に圧接して摩擦抵抗材 961による摩擦 抵抗によって回転を抑止できるようになっているとともに、隙間 29から圧縮空気を抜 けば、摩擦抵抗が弱くなり、把手部 22を頭部ハウジング 23aとともに、駆動軸 4の周り をスムーズに回転させることができるようになって 、る。 [0045] Then, the straight sander le opens the valve 292 and feeds compressed air into the gap 29 via the compressed air supply passage 291. The straight sander le causes frictional resistance via the biasing force transmission member 96e by the pressure of the compressed air. The material 961 is pressed against the upper surface of the collar 251 so that rotation can be suppressed by the frictional resistance of the frictional resistance material 961. If compressed air is extracted from the gap 29, the frictional resistance becomes weaker, and the handle 22 With the head housing 23a, the drive shaft 4 can be smoothly rotated.
[0046] 図 9は、本発明に力かる手持ち研磨装置であるォービタルサンダの実施の形態を あらわしている。 FIG. 9 shows an embodiment of an orbital sander that is a hand-held polishing apparatus that is useful for the present invention.
