【考案の詳細な説明】 本考案は黒板消しに関する。[Detailed explanation of the idea] This invention relates to a blackboard eraser.
従来、黒板消しは、字消し部材を取付けた板
と、これに固定したバンドとの間に手を出入れす
るようになつているため、頻繁に使用する場合に
は、前記のような手の出入れが煩わしいという問
題があり、そのため、一般に前記のバンドに手を
通さずに前記板を直接持ことが多いが、そのよう
にすると、手から滑り落ち易いという別の問題を
有していた。 Conventionally, with blackboard erasers, you have to put your hand in and out between the board with the eraser attached and the band fixed to it, so if you use it frequently, There is a problem that it is cumbersome to put in and take out, and therefore, the board is often held directly without passing the hand through the band, but when doing so, there is another problem that it easily slips out of the hand. .
本考案は上記の問題に鑑みて為されたもので、
使用する際に持ち易く且つ手から滑り落ちること
のない、新規な黒板消しを提供することを目的と
するもので、その特徴とするところは、弾力を有

にある。 This idea was created in view of the above problems.
The purpose of this product is to provide a new blackboard eraser that is easy to hold and does not slip out of the hand when in use.The main feature of this eraser is that one side of the elastic block body is designed to allow you to rest your thumb on one side. A concave portion is formed on the other side, and a concave portion on which fingers other than the thumb are individually hung is formed on the other side.
以下、本考案の一実施例を図面に基いて説明す

な布地で覆つてもよい。 Hereinafter, one embodiment of the present invention will be explained based on the drawings. The blackboard eraser 1 is made of rubber or polyurethane foam, etc., and has elasticity, and is formed into a flat and substantially fan-shaped surface with a convex curved surface. For example, a recess 3 on which the thumb is hung, and a recess 4 on which fingers other than the thumb, ie, fingers from the index finger to the little finger, are hung, are formed in, for example, the lower and upper peripheral edges of the block body 2. In addition to the surface roughness for use as a blackboard eraser, the degree of elasticity of the block body 2 may be appropriately set depending on the composition of the material, foaming density, etc., and it may also be formed hollow. may be covered with a fabric such as velvet.
かかる黒板消し１は、親指を下側の凹部３に、
親指以外の指を上側の凹部４にそれぞれ掛け、ブ
ロツク体２の弾力に抗して軽く力を入れてつまむ
ことにより、ブロツク体２の例えば略中央部を字
消し面として使用することができる。この場合、
黒板消し１は、軽くつまむだけでも、凹部３，４
によりそれぞれの指がその側面方向にずれること
が抑えられ、且つ、指の押圧力に対してブロツク
体２の反発力が作用するので、手から滑り出すこ
とが防止されるものである。 With this blackboard eraser 1, place your thumb into the recess 3 on the lower side.
By hooking each finger other than the thumb onto the upper recess 4 and pinching it with light force against the elasticity of the block 2, it is possible to use, for example, approximately the center of the block 2 as an eraser surface. in this case,
Blackboard eraser 1 can be easily removed from the recesses 3 and 4 by just pinching it lightly.
This prevents each finger from shifting in the lateral direction, and since the repulsive force of the block body 2 acts against the pressing force of the fingers, it is prevented from slipping out of the hand.
以上述べたように、本考案に係る黒板消しは、
弾力を有するブロツク体の一方の側には親指を掛
ける凹部を、他の一方の側には前記の親指以外の
指をそれぞれ別個に掛ける凹部を、それぞれ形成
したものであるから、指を前記凹部に掛けて軽く
つまむようにするだけで確実に持つことができる
ので頻繁に使用する場合でも煩しさがなく、しか
も持つたときに前記凹部と弾力性とによつて手、
各指との一体感が良好なため、手から滑り落ちて
衣服や床等を白墨粉で汚すこともないという実用
的効果を奏するものである。 As mentioned above, the blackboard eraser according to the present invention is
One side of the resilient block body is formed with a recess for hanging the thumb, and the other side is formed with a recess for hanging the fingers other than the thumb separately, so that the fingers can be placed in the recess. You can hold it securely just by hanging it on your phone and pinching it lightly, so it won't be bothersome even if you use it frequently.
Since it has a good sense of unity with each finger, it has the practical effect of not slipping from the hand and staining clothes, floors, etc. with chalk powder.
なお、本考案の実施の態様は前述したところに
限定されるものではなく、例えば、ブロツク体に
設ける凹部の形状、個数、配置等は適宜設定し得
るものである。また、本考案は、従来の黒板に替
つて最近しばしば使用されている、いわゆる白板
に書いた文字等を消す用具についても適用し得る
ことはいうまでもない。 Note that the embodiment of the present invention is not limited to the above-described embodiment, and, for example, the shape, number, arrangement, etc. of the recesses provided in the block body can be set as appropriate. It goes without saying that the present invention can also be applied to tools for erasing characters written on so-called whiteboards, which have recently been frequently used in place of conventional blackboards.
