Abstract
A hinge rotates a cover pivotably connected to a device housing from a closed position to an open position. A shaft is connected to the cover. The shaft and cover have a common axis of rotation. A spring having a top end and a bottom end is affixed at its bottom end to the device housing. A line has a first end connected to the top end of the spring and a second end wound onto the shaft. When the cover is in the closed position, the spring is in an extended state. Upon release of the cover from the closed position, the spring force returns the spring toward a neutral state, thereby unwinding the line from the shaft and causing rotation of the cover to the open position.
Claims27
A hinge for rotating a cover pivotably connected to a device housing from a closed position to an open position, the hinge comprising:
- a shaft connected to the cover, wherein the shaft and cover have a common axis of rotation;
- a spring adjacent a side of the device housing, the spring having a top end and a bottom end, the bottom end being affixed to the device housing;
- a line having a first end and a second end, the first end of the line being connected to the top end of the spring, the second end of the line being wound onto the shaft, wherein when the cover is in the closed position, the spring is in an extended state, and upon release of the cover from the closed position, the spring returns toward a neutral state, thereby unwinding the line from the shaft, causing rotation of the cover to the open position.
A hinge for rotating a cover relative to a device housing from a closed position to an open position, the hinge comprising:
- a pair of support members connected to the device housing, the cover rotatably held between the support members;
- a shaft connected to the cover, wherein the shaft and cover have a common axis of rotation;
- a spring adjacent a side of the device housing, the spring having a top end and a bottom end, the bottom end being affixed to the device housing;
- a line having a first end and a second end, the first end of the line being connected to the top end of the spring, the second end of the line being wound onto the shaft, wherein when the cover is in the closed position, the spring is in an extended state, and upon release of the cover from the closed position, the spring returns toward a neutral state, thereby unwinding the line from the shaft, causing rotation of the cover to an open position.
A hinged device comprising:
- a housing having a pair of support members extending from opposite sides of the housing, at least one of the support members having a bore;
- a cover rotatably connected to the support members, the cover positioned over the housing when the cover is in a closed position;
- a shaft extending from at least one end of the cover through the bore outside the support member;
- a spring adjacent a side of the housing, the spring having a top end and a bottom end, the bottom end being affixed to the housing;
- a line having a first end and a second end, the first end of the line being connected to the top end of the spring, the second end of the line being wound onto the shaft which extends through the bore outside the support member, wherein when the cover is in the closed position, the spring is in an extended state, and upon release of the cover from the closed position, the spring returns toward a neutral state, thereby unwinding the line from the shaft, causing rotation of the cover to an open position.
