Abstract
A portable device includes a first body element, a second body element, and a hinge assembly to allow the second body element to slide and rotate, and to vary the vertical arrangement between the first body element and the second body element while remaining parallel to each other. The hinge assembly has a first end rotatably coupled to the first body element and a second end rotatably and slidably coupled to the second body element to allow the first body element and the second body element to slide and vary the vertical arrangement therebetween while staying parallel to each other.

A hinge assembly coupled between a first plate and a second plate of a portable device, comprising:
- a base element;
- a first rotation element comprising a first rotational axel, which is coupled to the first plate and is rotatably coupled to the base element, and a first gear coupled to the first rotational axel;
- a second rotation element comprising a second rotational axel, which is coupled to the second plate and is rotatably coupled to the base element, and a second gear coupled to the second rotational axel;
- a power transfer gear rotatably coupled to the base element and arranged to transfer rotation torque between the first gear and the second gear;
- and
- an elastic module to restrict rotation of the base element relative to the first rotation element,
- wherein rotation of the hinge assembly causes a vertical arrangement between the first plate and the second plate to vary while maintaining a parallel arrangement of the first plate and the second plate.
A portable device, comprising:
- a first body element comprising a first thick portion and a first thin portion;
- a second body element comprising a second thick portion and a second thin portion, the second thick portion to contact the first thin portion, and the second thin portion to contact the first thick portion if the portable device is in a closed position;
- and
- a hinge assembly comprising a first end rotatably coupled to the first body element and a second end rotatably and slidably coupled to the second body element, the hinge assembly to rotate the portable device between an open position and a closed position, and to vary the vertical arrangement between the first body element and the second body element while maintaining a parallel arrangement of the first body element and the second body element.
