A hinge apparatus has a first attachment member to be attached to a housing, a second attachment member to be attached to a door; and first and second links, respective basal end portions of the first and the second links rotatably attached to the first attachment member, respective distal end portions of the first and the second links rotatably attached to the second attachment member. The first attachment member, the second attachment member, the first link and the second link constitute a link mechanism. The first attachment member has a base member to be attached to the housing, and a connecting member removably attached to the base member. The basal end portions of the first and the second links are rotatably attached to the connecting member. The connecting member, the second attachment member, the first link and the second link constitute a link mechanism. |

1. A hinge apparatus comprising:
a first attachment member to be attached to a housing; a second attachment member to be attached to a door; and first and second links, respective basal end portions of the first and the second links rotatably attached to the first attachment member, respective distal end portions of the first and the second links rotatably attached to the second attachment member; wherein the first attachment member comprises:
a base member to be attached to the housing; anda connecting member removably attached to the base member; wherein the basal end portions of the first and the second links are rotatably attached to the connecting member; wherein the connecting member, the second attachment member, the first link and the second link constitute a link mechanism,
wherein a rotation axis about which the connecting member and the first link rotate is defined as a first rotation axis,wherein a rotation axis about which the connecting member and the second link rotate is defined as a second rotation axis,wherein a rotation axis about which the second attachment member and the first link rotate is defined as a third rotation axis,wherein a rotation axis about which the second attachment member and the second link rotate is defined as a fourth rotation axis,wherein a distance between the first rotation axis and the second rotation axis is equal to a distance between the third rotation axis and the fourth rotation axis, andwherein a distance between the first rotation axis and the third rotation axis is equal to a distance between the second rotation axis and the fourth rotation axis; wherein the hinge apparatus further comprises a third link that constitutes the link mechanism with the connecting member, the second attachment member, the first link, and the second link; wherein a fifth rotation axis of a basal end portion of the third link with respect to the connecting member is arranged to form a triangle with the first rotation axis and the second rotation axis, and wherein a rotation axis about which the second attachment member and the distal end portion of the third link rotate is defined as a sixth rotation axis; wherein the first, the second and the third links are bent in respective intermediate portions; and wherein the bent portions of the first, the second and the third links are positioned on a same side with respect to straight lines connecting respective rotation axes of the respective basal end portions of the first, the second and the third links and respective rotation axes of the respective distal end portions of the first, the second and the third links. |
