Description
【考案の詳細な説明】 この考案は、黒板拭のチョークの粉を落とす掃除用器具に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning device for removing chalk powder from a blackboard wiper.
従来、黒板拭の掃除は、棒で叩くか専門の電気掃除機でやるが、棒で叩くのは 埃や騒音が出たり、黒板の使用中には使えず、また、電気掃除機は設置費や設置 場所、維持費などに問題があった。 Conventionally, blackboard wipes can be cleaned with a stick or with a specialized vacuum cleaner. There were problems with installation, installation location, maintenance costs, etc.
本考案は、これらの欠点を克服するためになされたもので、これを図面につい て説明すれば、図１のように、縁止めをしたメッシュ金網１の四隅を、隙間調整 用ワッシャー２と、金網押さえ用ワッシャー３を通したネジ釘４で、黒板の片隅 に取付けて黒板拭掃除盤としたものである。 The present invention has been made to overcome these drawbacks. Referring to the drawings, as shown in FIG. A screw nail 4 passed through a wire mesh holding washer 3 is attached to one corner of the blackboard to form a blackboard wiper.
本考案は、このような構造であるから、掃除盤の上を黒板拭で数回擦るだけで チョークの粉を分離させ掃除することができる。また、ほこりや騒音も出ないた め、黒板の使用中でも利用することができる。 Since the present invention has such a structure, the chalk powder can be separated and cleaned only by rubbing the cleaning board several times with a blackboard wiper. In addition, since there is no dust or noise, it can be used even while using the blackboard.
チョークの粉末は、黒板と掃除盤の隙間から黒板の溝に落ちて溜まるので、黒 板の掃除のときに、一緒に容易に片附けることができる。 The chalk powder drops from the gap between the blackboard and the vacuum cleaner into the groove of the blackboard and accumulates, so that it can be easily cleared together when cleaning the blackboard.
装置は軽便で、取付けもいたって簡単であるため安価に設置できる。さらに、 黒板に密着しているため邪魔にならず、手動であるため電気も不要で、維持費も かからない。 The device is light and easy to install, so it can be installed inexpensively. Furthermore, it is not in the way because it is in close contact with the blackboard, and because it is manual, it does not require electricity and does not require maintenance costs.

【図２】本考案の一部拡大の斜視図である。FIG. 2 is a partially enlarged perspective view of the present invention.
