LIFT HINGE DEVICE
To make a door open and close in a smooth manner by reducing loads when the door is opened to improve the operability, making the door operate as slowly as possible when the door closes automatically to improve the safety, and improving the load bearing ability of a roller to enhance the durability.SOLUTION: A lift hinge device includes one member 1 attached to a door frame F; another member 2 attached to a door D; a shaft 10 provided in the member 1; a bearing part 20 that is provided in the member 2, and that is pivotally supported by the shaft 10 so as to be movable in the direction of a center axis P of the shaft 10 and rotatable about the center axis P; a roller 50 on the member 1 side which is provided on a circle whose center is the center axis P; and a cam 70 on the member 2 side which raises and moves the door D when the door D is opened because the roller 50 rotates. A support shaft 53 with an axis Q perpendicular to the shaft 10 is provided on the shaft 10 in a protruding manner. The roller 50 is formed in a wheel shape and rotatably supported by the support shaft 53.SELECTED DRAWING: Figure 3
【課題】 ドアを開く際の負荷を低減して操作性を向上させ、ドアの自閉の際にはできるだけゆっくりと作動するようにして安全性を向上させ、ローラの耐荷重性を向上させて耐久性を向上させ、ドア開閉の円滑化を図る。【解決手段】 ドア枠Ｆに取付けられる一方部材１と、ドアＤに取付けられる他方部材２と、一方部材１に設けられた軸部２０と、他方部材２に設けられ軸部１０にその中心軸Ｐ方向に移動可能且つ中心軸Ｐを中心に回動可能に軸支される軸受部２０と、一方部材１側であって中心軸Ｐを中心とする円周上に設けられるローラ５０と、他方部材２側であってローラ５０が転動しドアＤの開時にドアＤをせり上げ移動させるカム７０とを備え、軸部１０にこれに直交する軸線Ｑを有した支持軸５３を突設し、ローラ５０をホイール状に形成して支持軸５３に回転可能に支持した。【選択図】 図３
