DOOR CATCHER AND HINGED DOOR
To provide a door catcher that can improve operability while reducing the production cost using a configuration without a permanent magnet.SOLUTION: The door catcher is composed of a door-side member A provided to a door 11 and a floor-side member B provided to a floor F. The door-side member A includes a base body 2 attached to a side surface in an opening direction C1 of the door 11, and a lifted/lowered body 3 that is supported by the base body 2 so that it can be lifted and lowered and that forwards and retracts from the lower surface of the base body 2. The lifted/lowered body 3 has a shape in which its lower end has a smaller diameter as it goes downwards. When lifted, the lifted/lowered body 3 changes the shape of an elastic body 4, and this causes downward elastic biasing forces. The floor-side member B includes: a climb-over protrusion 7 over which the lifted/lowered body 3 that moves together with the door 11 when the door 11 is opened climbs after rising against the elastic biasing forces and then dropping; and a base body stopper ST1 that stops the base body 2 so as to limit the movement of the base body 2 in the opening direction C1 at the position where the lifted/lowered body 3 climbs over the climb-over protrusion 7.SELECTED DRAWING: Figure 9
【課題】永久磁石を使用しない構成で製造コストを低減しながら操作性を向上できるドアキャッチャーを提供する。【解決手段】扉１１に設ける扉側部材Ａと、床面Ｆに設ける床側部材Ｂとからなる。扉側部材Ａは、扉１１の開方向Ｃ１側面に取り付ける基体２と、基体２により昇降可能に支持され、基体２の下面から出没する昇降体３とを備える。昇降体３は、その下端部が下方へ行くにしたがって縮径する形状を成し、昇降体３が上昇すると、弾性体４を変形させて下方への弾性付勢力が生じる。床側部材Ｂは、扉１１を開ける際に、扉１１とともに移動する昇降体３が、前記弾性付勢力に抗して上昇した後に下降して乗り越える乗越え凸部７と、昇降体３が乗越え凸部７を乗り越えた位置で、基体２の開方向Ｃ１への移動を規制するように基体２を当止する基体当止部ＳＴ１とを備える。【選択図】図９
