Hinge supporting device and electronic equipment using the same
A hinge holding device for firmly holding a pair of enclosures in an open or closed state has a base frame sandwiched between the pair of enclosures and supporting the pair of enclosures in an open or closed state, and a suction mechanism having a load generator disposed within at least one of the pair of enclosures. The suction mechanism generates a non-linear load between the base frame and one of the enclosures to maintain the open and closed state of one of the enclosures with respect to the base frame.
1 . A hinge holding device for holding a pair of enclosures in an open or closed state, comprising:
a base frame sandwiched between said pair of enclosures and supporting said pair of enclosures in an open or closed state each, and
a suction mechanism in which a load generator is located within at least one of said pair of enclosures, said suction mechanism generating a non-linear load between the base frame and one of the enclosures to maintain the open and closed state of the one enclosure with respect to the base frame.
2 . The hinge holding device as claimed in claim 1 , wherein the suction mechanism has an arm pivotably supported by the base frame and slidably connected to one of the enclosures, and wherein the load generator controls the sliding movement between the arm and one of the enclosures.
3 . The hinge holding device as claimed in claim 2 , wherein the load generator comprises a slider cam connected to the arm and sliding against one of the enclosures, and a spring bracket on one of the enclosures and moving in a first direction different from the sliding direction.
4 . The hinge holding device as claimed in claim 3 , wherein a cam apex of a cam on the slider cam and a cam apex of a cam on the spring bracket contact each other in an intermediate state between the open and closed states of one of the enclosures with respect to the base frame.
5 . The hinge holding device according to claim 4 , wherein the load generator reduces the load exerted by the spring bracket on the slider cam as it approaches the open or closed state of one of the enclosures from the intermediate state.
6 . The hinge holding device according to claim 3 , wherein the slider cam is rotatably supported on the arm around an axis that is parallel to the open/close axis of one of the enclosures.
7 . The hinge holding device according to claim 1 , wherein the device is an electronic device.
