DOOR HINGE STRUCTURE
To provide a door hinge structure capable of smoothly opening/closing a door by preventing each cam member from locally abutting during rotating action of the cam member, and capable of increasing a life.SOLUTION: A fixed side cam member 12 of a fixed side hinge member 10 includes a plurality of fixed side cam protrusions 14 provided in a circumferential direction, and a fixed side cam recessed portion 15 positioned between the fixed side cam protrusions 14. A moving side cam member 22 of a moving side hinge member 20 includes a plurality of moving side cam protrusions 24 provided in a circumferential direction and engaged with the fixed side cam recessed portion 15, and a moving side cam recessed portion 25 positioned between the moving side cam protrusions 24 and receiving the fixed side cam protrusion 14. A first inclined cam surface 16a connecting the fixed side cam protrusion 14 and the fixed side cam recessed portion 15, a second inclined cam surface 16b, a third inclined cam surface 26a connecting the moving side cam protrusion 24 and the moving side cam recessed portion 25, and a fourth inclined cam surface 26b are formed in a curved shape.SELECTED DRAWING: Figure 4
【課題】カム部材の回動動作時において、各カム部材が局所的に当接してしまうことを防止し、扉の円滑な開閉を行うことができるとともに、長寿命化を図ることができる扉のヒンジ構造を提供する。【解決手段】固定側ヒンジ部材１０の固定側カム部材１２は、周方向に複数設けられた固定側カム突起１４と、固定側カム突起１４の間に位置する固定側カム凹部１５とを備え、可動側ヒンジ部材２０の可動側カム部材２２は、周方向に複数設けられ固定側カム凹部１５に係合される可動側カム突起２４と、可動側カム突起２４の間に位置し、固定側カム突起１４を受け入れる可動側カム凹部２５とを備え、固定側カム突起１４と固定側カム凹部１５を結ぶ第１傾斜カム面１６ａ、第２傾斜カム面１６ｂおよび可動側カム突起２４と可動側カム凹部２５を結ぶ第３傾斜カム面２６ａ、第４傾斜カム面２６ｂは、曲面状に形成されている。【選択図】図４
