Abstract

<P>PROBLEM TO BE SOLVED: To provide a cleaning tool for a blackboard eraser, by which the blackboard eraser can easily and quickly be cleaned without scattering chalk powder of the blackboard eraser, on the periphery. <P>SOLUTION: The blackboard eraser is put in a certain container, and a plurality of sticks are vertically moved at intervals of time by turning of a handle, for beating the face of the blackboard eraser vigorously with a spring force. The chalk powder beat out into the container is absorbed and collected at a prescribed place by a sucking means. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、黒板拭きに付着しているチョ−クの粉末を吸引するようになる黒板拭きの掃除具に関するものである。  The present invention relates to a cleaning tool for wiping blackboard that sucks choke powder adhering to blackboard wiping.

黒板拭き付着しているチョ−ク粉末等は、黒板拭きを棒等で叩いて除去するようにしており、これを機械的に除去する器具等は全く存在しない。  The chalk powder adhering to the blackboard wipe is removed by hitting the blackboard wipe with a stick or the like, and there is no instrument or the like for removing this mechanically.

黒板拭きを棒等で叩いてチョ−ク粉末を除去するようにすると、チョ−ク粉末が教室内等に飛散し、周囲を汚すばかりでなく、健康的にも問題がある。
本発明は、前記従来の欠点を一掃し、チョ−ク粉末の飛散を防止し、これを一定の箇所に吸引収集するようになる黒板拭きの掃除具を提供することを目的としたものである。If the chalk powder is removed by wiping the blackboard wipe with a stick or the like, the chalk powder scatters in the classroom and so on, and not only pollutes the surroundings but also causes a health problem.
An object of the present invention is to provide a blackboard wiping cleaning tool that eliminates the above-mentioned conventional drawbacks, prevents scattering of the choke powder, and sucks and collects the powder at a predetermined location. .

本発明は、前記の目的を達成する手段として、黒板拭きの格納部２を有する台盤１と、複数個の通気孔３を穿設けしてなる蓋体４と、吸引口５を付設してなる台盤１の側壁１ａに固定した支軸６回動可能に軸装され且つスプリング７によって下方に牽引されている複数個の叩棒８と、手動ハンドルによって回転し、軸上には螺旋状に配置されている複数個のカム１０を突設してなる回転軸１１とからなり、ハンドル９の回転よって回転軸１１を回転し、カム１０が叩棒８を立上げてスプリング７の力で黒板拭きの面を若干時間差をつけて叩き、この叩き出したチョ−ク粉末を吸引器で所定箇所に収集するようにした。  As means for achieving the above object, the present invention is provided with a base plate 1 having a blackboard wiping storage portion 2, a lid 4 formed with a plurality of vent holes 3, and a suction port 5. The support shaft 6 fixed to the side wall 1a of the base plate 1 is pivotally mounted so as to be pivotable and pulled downward by a spring 7, and is rotated by a manual handle. The rotating shaft 11 is formed by projecting a plurality of cams 10 disposed on the rotating shaft 11, and the rotating shaft 11 is rotated by the rotation of the handle 9. The surface of the blackboard wipe was struck with a slight time difference, and the struck choke powder was collected at a predetermined location with an aspirator.

本発明は、黒板拭きを一定の容器内に入れて叩棒５でチョ−ク粉末を叩き出しこのチョ−ク粉末を吸引器で所定箇所に収集するようになるもので、チョ−ク粉末を室内に飛散させずに黒板拭きの掃除を簡便且つ迅速に遂行し得る利点を有するものである。  In the present invention, blackboard wipes are placed in a fixed container, and the choke powder is struck out with the hitting stick 5, and the choke powder is collected at a predetermined location with an aspirator. It has the advantage that the blackboard wipe can be easily and quickly cleaned without being scattered in the room.

本発明の具体的な構成を図に基づいて説明すると、台盤１は、底面から黒板拭きＡを入れるようになる黒板拭きの格納部２を有し、両側に設けた側壁１ａの一方の側壁に吸引口５を付設してある。  A specific configuration of the present invention will be described with reference to the drawings. The base board 1 has a blackboard wiping storage portion 2 into which the blackboard wiping A is inserted from the bottom, and one side wall of the side wall 1a provided on both sides. Is provided with a suction port 5.

前記台盤１の側壁１ａには支軸６と、ハンドル９によって回転する回転軸１１が横架されており、そして、支軸６上には４個の叩棒８が等間隔に回動可能に装嵌され、叩棒８の先端には叩棒を下方に強く牽引するスプリング７が張設され、該叩棒８の基方部に扁平部８ａが形成されている。  A supporting shaft 6 and a rotating shaft 11 rotated by a handle 9 are horizontally mounted on the side wall 1a of the base plate 1, and four hitting bars 8 can be rotated on the supporting shaft 6 at equal intervals. A spring 7 that strongly pulls the hitting bar downward is stretched at the tip of the hitting bar 8, and a flat part 8 a is formed at the base part of the hitting bar 8.

前記回転軸１１上には、前記叩棒８の配列間隔に対応した間隔で螺旋状に複数個のカム１０が突設されており、このカム１０が前記叩棒８の扁平部に接して叩棒を立上げてカム１０の接触が解除したとき前記スプリング７の力で黒板拭きＡの面を強く叩き、チョ−ク粉末を叩き出し、そして、カム１０は、螺旋状に配置されているため４個の叩棒８は夫々時間差をつけて黒板拭きＡを叩くようになるものである。  On the rotating shaft 11, a plurality of cams 10 are spirally provided at intervals corresponding to the arrangement interval of the hitting rods 8, and the cams 10 are in contact with the flat portions of the hitting rods 8. When the stick is raised and the contact of the cam 10 is released, the surface of the blackboard wipe A is struck by the force of the spring 7 and the choke powder is struck, and the cam 10 is arranged in a spiral shape. The four hitting sticks 8 come to strike the blackboard wipe A with a time difference.

前記台盤１には、透明のプラスチック等からなる着脱可能な蓋体４があり、この蓋体４に複数個の通気孔３を穿設してあり、吸引口５に装着した吸引器によってチョ−ク粉末の吸引を可能にしている。尚、図中１２は、黒板拭きＡの格納部の蓋体である。The base plate 1 has a detachable lid 4 made of transparent plastic or the like. A plurality of vent holes 3 are formed in the lid 4, and a choke is attached to the suction port 5 by a suction device. -Allows suction of powder. In the figure, reference numeral 12 denotes a cover of the storage unit for the blackboard wipe A.
