Summary: | To provide a board for learning 1 in which the transparent film 3 is easy to replace.SOLUTION: A cross section of a fastener 4 is U-shaped, and a long side 2C of the upper side of a board body 2 is fitted into the fastener 4 and fixed. A transparent film 3 has a belt-shaped part 3B which continues from the long side 3A of its upper side and is folded outward, and an insertion part 3C is formed by the long side 3A and the belt-shaped part 3B. And a receiving recess 4E capable of receiving the insertion part 3C is formed between a front grappling part 4B of the fastener 4 and a surface 2A of the board body 2, and a step part 4D is formed on the inner surface of the front grappling part 4B. When said insertion part 3C is inserted between the surface 2A of the board body 2 and the front grappling part 4B of the fastener 4, the insertion part 3C is received inside the receiving recess 4E and the lower end of the belt-shaped part 3B comes into contact with the step part 4D and the transparent film 3 is held by the fastener 4.SELECTED DRAWING: Figure 5
【課題】透明フィルム3の交換が容易な学習用ボード1を提供する。【解決手段】留め具4の断面はコ字形となっており、ボード本体2の上方側の長辺2Cが留め具4に嵌め込まれて固着されている。透明フィルム3は、その上方側の長辺3Aから連続して外方へ折り返された帯状部3Bを備えており、長辺3Aと帯状部3Bとで差し込み部3Cが形成されている。また、留め具4の前方挟持部4Bとボード本体2の表面2Aとの間に、上記差し込み部3Cを収容可能な収容凹部4Eが形成されるとともに、前方挟持部4Bの内面に段部4Dが形成されている。上記差し込み部3Cを、ボード本体2の表面2Aと留め具4の前方挟持部4Bとの間に差し込むと、差し込み部3Cが収容凹部4E内に収容されるとともに帯状部3Bの下端が段部4Dに当接して、留め具4により透明フィルム3が保持される。【選択図】 図5 |
