Abstract: A hinge assembly attaches a cover pivotally to a base of an electronic device and has a stationary leaf, a bushing and a pivoting leaf The stationary leaf is attached to the base and has a barrel and two slots. Each slot is formed in the barrel. The bushing is mounted in the barrel and has two end edges and two securing members. Each securing member is formed from the bushing and is mounted in the corresponding slot. The pivoting leaf is mounted rotatably in the bushing and attaches to the cover. Consequently, the hinge has a small bushing and uses less material reducing the size and weight of the hinge assembly, and the same of the electronic device.

Abstract: A pivotal-axis changing hinge has a stationary leaf, a pivoting leaf, a pintle assembly and a cam. The pivoting leaf and stationary leaf are respectively connected securely to a cover having a rear edge and a keyway and a base having an elongated gudgeon. A parabolic edge is formed at an edge near the elongated gudgeon. The pintle assembly is mounted through the keyway and pivotally through the elongated gudgeon to allow the leaves to pivot along a pivotal axis of the pintle assembly. The cam is mounted on the pintle assembly, rotates simultaneously with the pintle assembly and has a protrusion mounted slidably on the parabolic edge to move the pintle assembly and the cover perpendicularly away from the base when the cover is pivoting. Consequently, the proximal edge of the cover is kept from colliding with the base and the rotating angle of the cover is expanded.

Abstract: A hinge with less noise pivotally connects to a cover and a base of an electrical appliance and has a stationary-positioning element, a rotating-positioning element and a noise-eliminated spacer. The stationary-positioning element is mounted securely in the base and has at least one positioning protrusion. The rotating-positioning element is mounted securely in the cover and has at least one positioning detent corresponding to the positioning protrusion when the cover is closed. The noise-eliminated spacer is attached to the rotating-positioning element to let the stationary-positioning element and the rotating-positioning element in constant contact, which results in friction between the stationary-positioning element and the rotating-positioning element being uniform. The noise-eliminated spacer is made by metal stamping process to well form the size of the through hole for tightly engage the deformed portion of the shaft to eliminate noise.

Abstract: A hinge has a pintle, a moving leaf, a resilient device and a stationary leaf. The pintle has a resilient device mount formed on a distal end and is mounted securely in the stationary leaf. The moving leaf is mounted rotatably around the pintle and has a barrel having a protruding limit formed on an outer end. Because the resilient device mount is formed on the pintle, it does not break easily and may slip to prevent terminal failure and be reset when closed. The protruding limit abuts the stationary leaf and ensures a gap is formed between the leaves for wires cabling or the like. Therefore the hinge has improved wear and longer lifespan.
