Description

この発明は、ディスクグラインダーを覆う集じん機カバーであって、四角状に形成されるとともに、その左右および先端部に切欠部が設けられており、これらの切欠部から研磨材の一部が突出されている事を特徴とする集じんカバーに関する物である。 The present invention is a dust collector cover that covers a disc grinder, which is formed in a square shape and has notches on the left, right, and tip thereof, and a part of the abrasive material protrudes from these notches. It is related to the dust collection cover, which is characterized by being used.

従来のディスクグラインダの集塵カバーには、色々な形を施したものがある(例えば、特許文献１参照) Dust collecting covers of conventional disc grinders have various shapes (see, for example, Patent Document 1).

特開２０１１－０５６６４１号公報Japanese Unexamined Patent Publication No. 2011-056641

しかしながら、特許文献１に示すディスクグラインダの集塵カバーは、次のような欠点が あった。
このディスクグラインダーの集塵カバーは図４の１０に示されるように、研磨材より大いカバーなので、基本的に1cm位の磨り残しが発生し、カバーも大きいため、狭い場所での作業性が悪く、カバー先端部の補助カバー12を外しても、ディスクグラインダーが縦方向に入る場所以外は隅の研磨が全く出来ません。 However, the dust collecting cover of the disc grinder shown in Patent Document 1 has the following drawbacks.
As shown in Fig. 4, the dust collection cover of this disc grinder is larger than the abrasive material, so basically there is about 1 cm of unpolished residue, and the cover is also large, so workability in narrow places is easy. Unfortunately, even if the auxiliary cover 12 at the tip of the cover is removed, the corners cannot be polished at all except where the disc grinder enters in the vertical direction.

本発明は、工具本体部に内装した電動モータにより回転する回転軸を備え、該回転軸に研磨材を取り付けるとともに、該回転軸を回転支持するハウジングに取り付けて前記研磨材の周囲の全周を集塵カバーで覆うディスクグラインダにおける前記集塵カバーであって、該集じんカバーは、四角状に形成されるとともに、その左右および先端部に切欠部が設けられており、これらの切欠部から研磨材の一部が突出されている事を特徴とする集じんカバーを提供することにより上記課題を解決したものである。 The present invention is provided with a rotating shaft that is rotated by an electric motor built in the tool body, and an abrasive is attached to the rotating shaft, and is attached to a housing that rotationally supports the rotating shaft to cover the entire circumference of the abrasive. The dust collection cover in a disc grinder covered with a dust collection cover, the dust collection cover is formed in a square shape, and notches are provided on the left, right, and tip portions thereof, and the dust collection cover is polished from these notches. The above problem is solved by providing a dust collecting cover characterized in that a part of the material is projected.

また、本発明は、前記集じん機カバーは、その一部に集じんを吸引するための吸引ダクトが接続されている事を特徴とする請求項１に記載の集じんカバーを提供することにより上記課題を解決したものである。 The present invention also provides the dust collecting cover according to claim 1, wherein the dust collecting machine cover is connected to a suction duct for sucking dust in a part thereof. This is a solution to the above problem.

前記集じんカバーは、ディスクグラインダー12のハウジング15に取り付けられ事で、様々なディスクグラインダー12取り付けられる。
集じんカバーは研磨材を覆うように四角状に形成されており、アルミ板の側面に切り込みを入れて、研磨材の欠部切を左右両側と先端部の３か所に設け、研磨材がはみ出るようにした事で、ディスクグラインダー14の向きに関係なく、狭い場所や天井、壁、梁、手すりの切り付けや目地の角の隅、（いわゆる際削り）が様々場面で研磨が出来るようになった。
前記集じん機カバーは、作業時に発生する粉じんが吸い込み用ダクトによって収集されるため、周囲に飛び散る事がなくなる請求項１又は2に記載の集じんカバーです。 The dust collecting cover is attached to the housing 15 of the disc grinder 12, so that various disc grinders 12 can be attached.
The dust collecting cover is formed in a square shape so as to cover the abrasive material, and a notch is made on the side surface of the aluminum plate, and a notch cut of the abrasive material is provided at three places on the left and right sides and the tip portion, and the abrasive material is provided. By making it stick out, regardless of the orientation of the disc grinder 14, it is possible to polish narrow places, ceilings, walls, beams, handrail cuts and corners of joints (so-called sharpening) in various situations. rice field.
The dust collector cover is the dust collector cover according to claim 1 or 2, because the dust generated during work is collected by a suction duct so that the dust does not scatter around.

前記集じんカバーは、ディスクグラインダー12のハウジング15に取り付けられ、研磨材を覆うように四角状に形成されている。 The dust collecting cover is attached to the housing 15 of the disc grinder 12 and is formed in a square shape so as to cover the abrasive material.

四角状の集じん機カバーは軽くて丈夫なアルミ板5で中心には、回転軸用に例えば直径4センチで開口を設け、その先端の右上に吸い込みダクト用の例えば2.5センチの穴を開ける。 The square dust collector cover is a light and durable aluminum plate 5. At the center, an opening with a diameter of 4 cm is provided for the rotating shaft, and a hole of 2.5 cm for the suction duct is made at the upper right of the tip.

アルミ板5は例えば厚さ２ミリで図２に示されるように例えば10センチの四角状の正方形で回りの端を研磨材を覆うように、折り曲げて加工する。 The aluminum plate 5 has a thickness of, for example, 2 mm, and is processed by bending the peripheral end into a square, for example, 10 cm, as shown in FIG. 2 so as to cover the abrasive.

折り曲げたアルミ板の側面に例えば縦５ミリ横５センチの切り込みを入れて、研磨材の欠部切を先端部と左右両側の３か所に設け、研磨材が突出するように形成する。 For example, a notch of 5 mm in length and 5 cm in width is made in the side surface of the bent aluminum plate, and cutouts of the abrasive material are provided at the tip portion and three places on the left and right sides so that the abrasive material protrudes.

アルミ板の加工が難しい場合は厚さ２ミリの10センチの正方形のアルミ板にL型のアングルを４方向に取り付けますが、ネジは振動で緩むので、強力な接着材で張り付ける。
同じようにアングルの側面に縦５ミリ横５センチ程度の切り込みを入れて、研磨材の切欠部を先端部と左右両側の３か所形成する。 If it is difficult to process the aluminum plate, attach an L-shaped angle to a 10 cm square aluminum plate with a thickness of 2 mm in four directions, but since the screws loosen due to vibration, attach them with a strong adhesive.
Similarly, a notch of about 5 mm in length and 5 cm in width is made on the side surface of the angle to form three notches on the tip and left and right sides.

吸い込みダクト用の穴に水柱エルボ3を強力接着剤で取り付け、回転軸用の開口にもパイプ1を強力な接着剤で取り付ける。 Attach the water column elbow 3 to the hole for the suction duct with a strong adhesive, and attach the pipe 1 to the opening for the rotating shaft with a strong adhesive.

後は集じん機カバー13をディスクグラインダー14の取り付け方法は集じんカバーの回転軸用の開口にディスクグラインダ14の回転軸を通し水平位置を確認して、研磨材の出具合を調整しながら、集じんカバー13が研磨材9より出ているかを注意して、しっかりとホースバンド2で締め付ける。 After that, attach the dust collector cover 13 to the disc grinder 14. To attach the disc grinder 14, pass the rotating shaft of the disc grinder 14 through the opening for the rotating shaft of the dust collecting cover, check the horizontal position, and adjust the amount of abrasive material. Make sure that the dust collection cover 13 comes out of the abrasive material 9, and tighten it firmly with the hose band 2.

ディスクグラインダー14のハウジング15に取り付けた、前記集じんカバーは研磨材の形に応じて、隙間が異なるため、周囲を養生テープやガムテープを張り付ければ粉じんを拡散しないように出来る。
Since the dust collecting cover attached to the housing 15 of the disc grinder 14 has a different gap depending on the shape of the abrasive, it is possible to prevent the dust from diffusing by attaching a curing tape or a gum tape to the surroundings.

前記集じんカバーは研磨材とほぼ同じ大きさで、狭い場所でも使用できるようになる。 The dust collection cover is about the same size as the abrasive and can be used even in a narrow space.

前記集じんカバーは図１に示されるように、軽くて丈夫なアルミ板を左右両側と先端部の三面に切り込みを入れ、図３に示されるように、研磨材がはみ出るようにした事で、ディスクグラインダー14の向きに関係なく、狭い場所や天井、壁、梁、手すりの切り付けや目地の角の隅、（いわゆる際削り）が様々場面で研磨出来るようになる。 As shown in FIG. 1, the dust collecting cover is made by cutting a light and durable aluminum plate on both the left and right sides and three sides of the tip so that the abrasive material protrudes as shown in FIG. Regardless of the orientation of the disc grinder 14, narrow spaces, ceilings, walls, beams, handrail cuts and corner corners of joints (so-called sharpening) can be polished in various situations.

左官業の命と言われる角を図6の16に示されるように（いわゆる際削り）がきれいに仕上げる事が出来る。
上記した構成とすれば、作業時に発生する粉じんが吸い込み用ダクトによって収集されるため、周囲に飛び散る事がなくなる。 As shown in 16 of Fig. 6, the corner that is said to be the life of the plasterer can be finished neatly (so-called sharpening).
With the above configuration, dust generated during work is collected by the suction duct, so that it does not scatter around.
