Description

本考案は芯材を紙管とした筒状の研磨用具に関するものである。 The present invention relates to a cylindrical polishing tool whose core material is a paper tube.

従来から木工加工製品などでのバリ取りや面取り、表面仕上げは紙やすりを用いて行われている。そして、木工加工に限るものではないが、大規模工場などでの建材の仕上げ加工においては、平たい補助板を紙やすりに裏当てして研磨作業ができる用具を利用しており、研磨粉が紙やすりの研磨面に目詰まりを起こし易くなるため、紙やすりとその裏当て材とに複数の孔を開け、研磨面側で生じる研磨粉をバキューム吸引することができる研磨用具が、例えば特許文献１に提案されている。 Conventionally, deburring, chamfering, and surface finishing of woodwork products have been performed using sandpaper. And, it is not limited to woodworking, but in finishing processing of building materials in large-scale factories, etc., tools that can be used for polishing work by backing a flat auxiliary plate against sandpaper are used. Since it becomes easy to cause clogging on the polishing surface of the file, a polishing tool capable of opening a plurality of holes in the sandpaper and the backing material and vacuuming the polishing powder generated on the polishing surface side is disclosed, for example, in Patent Document 1. Has been proposed.

また、木工品として組み上げられた製品、例えば椅子、家具などに対する研磨作業は作業者が手の感触を頼りに表面を削る作業が大半であり、木工加工での研磨用具としては作業者が片手持ちできる取り扱い容易なものが望まれている。その一種として、角筒状の用具本体の平たい側面に研磨材を設けるとともに、側面と側面との間に用具本体の内部に連通する隙間を開け、用具本体に接続するバキューム手段で、研磨時に生じる研磨粉を隙間を介して吸引できるようにした工夫が、特許文献２に示されている。 Also, most of the polishing work for products assembled as woodwork, such as chairs, furniture, etc., is the work of shaving the surface by relying on the feel of the hand, and as a polishing tool in woodworking, the worker has one hand What is easy to handle is desired. As one of them, a polishing material is provided on the flat side surface of the square tube-shaped tool body, and a gap is formed between the side surface and the inside of the tool body so as to communicate with the inside of the tool body. Japanese Patent Application Laid-Open No. 2004-228688 discloses a device that can suck abrasive powder through a gap.

さらに、円柱体を芯体としてこれに紙やすりを巻き付けて研磨することも行なわれており、研磨対象品の曲面を仕上げるに適した用具として利用される。なお、木工品が研磨する対象ではないが、紙管の外周面に研磨材を施して猫用の爪研ぎ具が特許文献３に示されており、このような紙管の外周面に研磨材を施したものを研磨用具とすれば、軽量であって研磨作業での取り扱いが頗る良好になると考えられている。 Further, a cylindrical body is used as a core body, and sandpaper is wound around the cylinder body for polishing, which is used as a tool suitable for finishing the curved surface of a product to be polished. In addition, although the woodwork is not a target to be polished, a nail sharpening tool for cats is shown in Patent Document 3 by applying an abrasive to the outer peripheral surface of the paper tube, and the abrasive on the outer peripheral surface of such a paper tube. It is considered that if a tool that has been subjected to polishing is used as a polishing tool, it is light in weight and can be easily handled in a polishing operation.

特開平０８−２９００９１号公報Japanese Patent Laid-Open No. 08-290091 登録実用新案第３０２７０９０号公報Registered Utility Model No. 3027090 登録実用新案第３１５４５９９号公報Registered Utility Model No. 3154599

上述した紙管の外周面に研磨材を施した構成のものを研磨用具にしてこれを研磨作業に使用した場合、上記円柱体に紙やすりを巻いて研磨する場合と同様にやはり研磨材の目が研磨粉で目詰まりし易いと考えられる。しかし、前記円柱体を芯体としたものでは目詰まりが進んだとしてもある程度の力を入れ続けていけば、研磨を行なうことができるものであるが、一方、紙管を芯体としているものでは作業者の力の入れ具合で紙管そのものが壊れてしまう。そのため、研磨用具のとして寿命が短いと考えられることから、安価で取り扱い容易であるメリットを活かせないという問題がある。 When the above-mentioned outer peripheral surface of the paper tube is made of a polishing tool and used for polishing work, the same as in the case of polishing by winding a sandpaper around the cylindrical body, is also used. Is likely to be clogged with abrasive powder. However, in the case where the cylindrical body is a core body, even if clogging progresses, polishing can be performed if a certain amount of force is continuously applied. On the other hand, a paper tube is used as the core body. Then, the paper tube itself will be broken by the power of the worker. Therefore, since it is thought that a lifetime is short as a polishing tool, there exists a problem that the merit which is cheap and easy to handle cannot be utilized.

そこで、本考案は上記事情に鑑み、紙管を芯体として外周面に研磨材を有する研磨用具での外周面で研磨材の目が研磨粉で目詰まりし難くなるようにすることを課題とし、紙管を芯体とする簡易な構成の筒状研磨用具を提供することを目的とする。 Therefore, in view of the above circumstances, the present invention has an object to make it difficult for the abrasive particles to be clogged with abrasive powder on the outer peripheral surface of a polishing tool having a paper tube as a core body and an abrasive on the outer peripheral surface. An object of the present invention is to provide a cylindrical polishing tool having a simple configuration using a paper tube as a core.

本考案は上記課題を考慮してなされたもので、紙管からなる芯材の周壁にこの周壁の周方向にして複数の透孔を開け、前記周壁の外周面に研磨材が設けられていて、芯材の一端部が閉じられているとともに、他端部側に吸引口を対応させて他端部を塞ぐ閉鎖面部を有して芯材の周壁の一部分を包被して握り面部を形成する握りカバーを備えており、前記握りカバーの吸引口に、管状にして吸引手段への拡縮可能な接続口が連通し、前記透孔から芯材内部を通して研磨粉を吸引排出可能な構成としたことを特徴とする筒状研磨用具を提供して、上記課題を解消するものである。 The present invention has been made in consideration of the above problems, and a plurality of through holes are formed in the peripheral wall of the core made of paper tube in the circumferential direction, and an abrasive is provided on the outer peripheral surface of the peripheral wall. One end of the core material is closed, and the other end side has a closed surface portion corresponding to the suction port to close the other end portion, and encloses a part of the peripheral wall of the core material to form a grip surface portion The grip cover is configured to be connected to the suction port of the grip cover so that the connection port can be expanded and contracted to the suction means, and the abrasive powder can be sucked and discharged from the through hole through the inside of the core member. The cylindrical polishing tool characterized by the above is provided to solve the above-mentioned problems.

本考案によれば、芯材の周壁の周方向にして複数の透孔が設けられていることから、研磨によって研磨粉が生じたとしても、研磨面側で生じる前記研磨粉を透孔を介して吸引によりその研磨面側から取り除くことができて、研磨材の目詰まりを防止することができるという効果を奏する。また、簡易な構成であるために一般的な掃除機の吸引ホースを接続口に繋いで吸引させることで、研磨面で生じる研磨粉を吸い取ることができ、研磨作業を学校の技術系工作室などにあるような塵芥吸引設備の下での作業とせずとも、一般的な居室、例えば学校の通常の教室で、物作りの実習でこの研磨用具に一般的な掃除機を接続しながら研磨作業を行なうようにしても簡単に研磨粉の飛散を防止できる。よって、研磨に際しての削りかす、研磨粉などの浮遊粉塵による呼吸器などへの悪影響を防ぐことができる。この点は一般家庭などで本研磨用具を一般掃除機に接続して吸引させながら研磨を行なうようにする場合でも同様の効果がある。 According to the present invention, since the plurality of through holes are provided in the circumferential direction of the peripheral wall of the core material, even if polishing powder is generated by polishing, the polishing powder generated on the polishing surface side is passed through the through holes. Thus, it can be removed from the polishing surface side by suction, and the clogging of the abrasive can be prevented. In addition, because of the simple structure, the suction hose of a general vacuum cleaner is connected to the connection port and sucked, so that the polishing powder generated on the polishing surface can be sucked off, and the polishing work can be done at the school's technical workshop, etc. Even if you do not work under the dust suction equipment as shown in Fig. 1, you can perform polishing work in a general living room, for example, a normal classroom in a school, with a general vacuum cleaner connected to this polishing tool in a manufacturing practice. Even if it carries out, it can prevent scattering of polishing powder easily. Therefore, it is possible to prevent adverse effects on the respiratory tract and the like due to dust particles during polishing and floating dust such as polishing powder. This point has the same effect even when polishing is performed while connecting this polishing tool to a general vacuum cleaner and sucking it in a general household.

つぎに本考案を図示の実施の形態に基づいて詳細に説明する。
図１は筒状研磨用具で、該筒状研磨用具１は図示するように紙管からなる芯体２と、この芯体２の端部に接続されて人が直接に握り持つことのできる太さとした握りカバー３とからなるものである。そして、前記芯体２は周壁４にこの周壁４の周方向にして複数の透孔５が開口され、さらに透孔５の部分を除く周壁４の外周面４ａに研磨材が施されて円筒状の研磨面６が形成されている。 Next, the present invention will be described in detail based on the illustrated embodiment.
FIG. 1 shows a cylindrical polishing tool. The cylindrical polishing tool 1 has a core body 2 made of a paper tube as shown in the figure, and a thick body that is connected to the end of the core body 2 and can be directly held by a person. It consists of a small grip cover 3. The core body 2 has a cylindrical shape in which a plurality of through holes 5 are opened on the peripheral wall 4 in the circumferential direction of the peripheral wall 4, and an abrasive is applied to the outer peripheral surface 4a of the peripheral wall 4 excluding the portion of the through holes 5. A polished surface 6 is formed.

芯体２の上記握りカバー３とは反対側の端部はシリコン樹脂製の閉鎖板７によって閉じられている。そして、握りカバー３は前記閉鎖板７と同様にシリコン樹脂製にして管状に形成されており、握りカバー３の一方の管状部分を芯体２の端部に嵌め付け、その握りカバー３の閉鎖面部３ａが芯体２の端部に相対させることで上述のように芯体２と握りカバー３とが接続されていて、前記握りカバー３における閉鎖面部３ａに配された吸引口３ｂが芯体２の内部に臨むように対応配置される。また、握りカバー３の閉鎖面部３ａの外面から外方に突出する筒状にして前記吸引口３ｂに連通する接続口８が一体に設けられており、この接続口８は拡縮可能とされていて、図示しない吸引手段への接続部分として形成され、図示のように例えば前記接続口８に吸引手段からの柔軟なバキュームパイプ９が接続される。 The end of the core 2 opposite to the grip cover 3 is closed by a silicone resin closing plate 7. The grip cover 3 is made of silicone resin and is formed in a tubular shape like the closing plate 7. One grip portion of the grip cover 3 is fitted to the end of the core body 2, and the grip cover 3 is closed. The core body 2 and the grip cover 3 are connected as described above by making the surface portion 3a face the end of the core body 2, and the suction port 3b disposed on the closed surface portion 3a of the grip cover 3 is a core body. 2 are arranged correspondingly so as to face the inside. In addition, a connection port 8 which is formed in a cylindrical shape protruding outward from the outer surface of the closing surface portion 3a of the grip cover 3 and communicates with the suction port 3b is integrally provided, and the connection port 8 can be expanded and contracted. As shown in the figure, a flexible vacuum pipe 9 from the suction means is connected to the connection port 8, for example.

以上のように、筒状研磨用具１では、芯体２の周壁４に複数の透孔５を備え、握りカバー３の接続口８に接続したバキュームパイプからの吸引を行なうことで、前記透孔５から芯体２の周りの空気を吸い入れてその芯体２の内部を通して空気を吸引元側に送り出すことができるようになっており、研磨時に前記吸引を行なうことで、研磨面側で生じた研磨粉を透孔５から芯材２内部を通して吸引排出できることとなり、研磨面での目詰まりを抑えることができる。 As described above, in the cylindrical polishing tool 1, the peripheral wall 4 of the core body 2 includes the plurality of through holes 5, and suction is performed from the vacuum pipe connected to the connection port 8 of the grip cover 3. The air around the core body 2 can be sucked in from 5 and the air can be sent out to the suction source side through the inside of the core body 2. Thus, the abrasive powder can be sucked and discharged from the through-hole 5 through the inside of the core member 2, and clogging on the polished surface can be suppressed.

上記実施の形態の説明においては芯体２を丸紙管からなるものとして図示しているが、本考案は芯体２が円筒形に限定されるものではなく、例えば図２に示されるように芯体２を断面形状が半円形の紙管を用いてなるものとしたり、角紙管を用いたものであってもよい。さらに図３では芯体２を角紙管からなる実施の形態を示していて、この実施の形態に示すように握りカバー３で芯体２の周壁の一部分としてほぼその三面を覆う形態とし、閉鎖板７も握りカバー３に一体としている。即ち、握りカバー３は研磨面６に握り手が直接触れ難くする役割を果たすものであり、形状自体は限定されないものである。 In the description of the above embodiment, the core body 2 is illustrated as being made of a round paper tube. However, the present invention is not limited to the cylindrical body 2, and for example, as shown in FIG. The core body 2 may be made of a paper tube having a semicircular cross section, or may be made of a square paper tube. Further, FIG. 3 shows an embodiment in which the core body 2 is formed of a square paper tube. As shown in this embodiment, the grip cover 3 covers the three surfaces as a part of the peripheral wall of the core body 2 and is closed. The plate 7 is also integrated with the grip cover 3. That is, the grip cover 3 plays a role of making it difficult for the grip hand to directly touch the polished surface 6, and the shape itself is not limited.
