Portable computer with cylinders providing friction in hinge

摘要

A portable computer may include a base, a lid, a base cylinder extending from the base, a lid cylinder extending from the lid, and a link. The link may couple the base cylinder to the lid cylinder fixing a positional relationship between the base cylinder and the lid cylinder so that the base cylinder frictionally engages with the lid cylinder.

主权项

1. A portable computer comprising:
a base; a lid; a base cylinder extending from the base, a length of the base cylinder being greater than a diameter of the base cylinder, the base cylinder including a base rod and a base shell encasing the base rod, the base shell having a lower hardness than the base rod; a lid cylinder extending from the lid, a length of the lid cylinder being greater than a diameter of the lid cylinder, the lid cylinder including a lid rod and a lid shell encasing the lid rod, the lid shell having a lower hardness than the lid rod; and a link coupling the base cylinder to the lid cylinder, a length of the link in a direction parallel to a direction in which the base cylinder and the lid cylinder extend through the link being greater than a width of the link in a direction perpendicular to the direction in which the base cylinder and the lid cylinder extend through the link, the link being in direct contact with both the base cylinder and the lid cylinder and fixing a positional relationship between the base cylinder and the lid cylinder so that the base shell frictionally engages with the lid shell.
