Description
このような構成は、上段棒(1)と下段棒(2)のリング(4)と磁石(5)の構成を相互位置を変えて構成することもできる。
また、上記リング(4)中段には、L字またはU字形態の磁石を挿入することができる溝を形成する。
即ち、図5に示すように、このような本発明は下段棒(2)にスクリーン(3)を巻き上げたあとに、上、下段棒(1,2)を密着させなければならないため、上、下段棒(1,2)の両端のリング(4)と磁石(5)を円形に構成するしかない。
この場合、上、下段棒(1,2)の両端にリング(4)と磁石(5)の形態を円形にのみ構成するときには図5aに示すように結合接点(A)が非常に小さくなり小さい力でも容易に上、下段棒(1,2)を分離することができる。
また、図8に示すように、上段棒(1)の両端の挿入口(10)に挿入された下段棒(2)はリング(4)に磁石(5)が固定されて離脱防止などの安定効果があり、ハンドル(11)を回して下段棒(2)を巻くとき、下段棒(2)のスクリーン(3)を安定に巻いて携帯することができる。
Claims (3)
- スクリーンの構成を、上、下段棒の間にスクリーンを付着して構成し、下段棒によりスクリーンを巻き上げることができるよう構成した壁掛けスクリーンにおいて、
スクリーン上段棒の左、右側端に鉄(Steel)のように磁性のある材質で加工したリングを付着し、
スクリーン下段棒の左、右側端に磁石を結合構成することにより、
携帯、移動時には下段棒によりスクリーンを巻き上げれば下段棒の左、右側の磁石が上段棒のリングと結合し、使用時には上記磁石とリングを分離させてスクリーンとして使用することができ、
リング部分に磁石がリング内部と結合することができる溝を形成したことを特徴とする壁掛けスクリーン。 - 請求項1において、上段棒の後面には付着装置を結合し、下段棒の後段部には付着装置を別途に壁に付着し、これをスクリーンの下段棒と結合構成してスクリーンが安定に付着、固定されることを特徴とする壁掛けスクリーン。
- 請求項1において、上段棒のリング構成と下段棒の磁石構成を相互位置を交換して構成したことを特徴とする壁掛けスクリーン。
