A hinge for a notebook computer has an L-shaped first seat with a first opening and a second opening. A barrel is mounted on the first seat, and has a rib received in the first opening, and an ear received in the second opening. A pintle rotatably extends in the barrel and mounted on a second seat by a butt of the pintle inserted through a third opening of the second seat. The first seat is mounted on an LCD monitor of the notebook computer, and the second seat is mounted on a body of the notebook computer. The hinge has a simple structure and a low cost.

Hinge for a notebook computer

An embodiment of a hinge assembly includes a main body defining a shaft hole, a connecting shaft including an inserting end rotatably received in the shaft hole, and an expansion member forming a tapered portion and axially positioned in the shaft hole. An end surface of the inserting end toward the expansion member defines a tapered hole corresponding to the tapered portion, and the tapered portion is pressed into the tapered hole to expand the inserting end to resist the inner surface of the shaft hole, thus rotatably connecting the connecting shaft to the main body.

Hinge assembly and electronic device using the same

A heat pipe hinge structure for an electronic device comprises a heat pipe hinge member and a hinge portion. The heat pipe hinge member is made of a high heat-conductive material disposed at a coupling portion in which a pair of housing portions to be opened and closed are coupled. The heat pipe hinge member comprises a heat pipe hinge main body to receive a heat from a heat generating component disposed in one of the pair of housing portions, and a heat pipe holding portion provided in a vicinity of the heat pipe hinge main body to pivotably hold by an elastic member at least a part of a first heat pipe disposed in other of the pair of housing portions. The hinge portion is made of a low heat-conductive material to fox the heat pipe hinge member on at least one housing portion of the pair of housing portions.

Heat pipe hinge structure for electronic device

The present invention is directed to a display mounting apparatus for mounting a flat screen television monitor or the like to a wall. The mounting apparatus provides four degrees of freedom for the flat screen display in lateral translation, tilt, swivel and pan directions. The combination of two two-link arms, counterbalancing torsion springs and friction mechanisms provides for ±20 degrees in the tilt and swivel directions.

Display mounting apparatus

A portable information handling system such as a laptop computer includes a chassis having a pivotally mounted top The chassis includes a keyboard and the top includes a display panel The top and chassis are connected by a hinge A hinge cap is releasably attached directly to the hinge and the hinge is mounted on the chassis A loose fit of the hinge cap on the hinge permits the hinge cap to float relative to the hinge Each of the hinge cap and a chassis cover plate include a mating, tapered surface so that when the hinge cap seats in the cover plate, the location of the hinge cap relative to the chassis cover plate is determined by the mating engagement

Snap-in floating hinge cap for portable computer

A hinge that provides equilibration and variable friction for a display screen or a laptop lid (7) In the preferred embodiment, a torsion rod (25) provides a restoring force which increases as the lid is moved either direction from its vertical position A friction hinge, of well know design, uses a spring band (23) about a shaft (21) One end of the torsion rod is coupled to the end of the band of the friction hinge, so that the moment in the torsion rod increases or decreases the moment in the spring band of the hinge, modifying the frictional torque accordingly This allows the frictional torque to be low as the lid is first opened, and larger as the display reaches the useful range of its motion

Equilibrated hinge with variable frictional torque

The present invention provides a small, cylindrical hinge, or pivoting pin (5), which can be configured to produce various profiles of torque versus angle. The desired profile of torque versus angle is achieved by the shapes of the hinge shaft and the spring plates (9) of the hinge. Detents at one or more angular positions can be achieved, with or without frictional damping torque at other angles. The friction of our hinge is produced symmetrically about the hinge axis, eliminating the problems associated with asymmetric construction.

Friction hinge with detent capability

A friction hinge assembly for a laptop computer which has a high thermal conductivity. The assembly includes a base element (23), a base element fixed to the base of the computer and to which an axially aligned base heat pipe (17) is coupled. The assembly also includes a lid element (35) fixed to the lid of the computer. The lid element has a body portion and a rotatable sleeve (33) attached to the lid and which receives a lid heat pipe (21). The base and lid elements are pre-assembled selectively fastenable to one another for ease of assembly of the lid to the base, and in order to control the frictional torque produced by the hinge during operation.

Friction hinge having high thermal conductivity

An inventive friction hinge is disclosed that uses two or more bands (3, 13) each operating in their loosening mode of operation The loosening mode is used to take advantage of the more reliable frictional characteristics that it provides Each band wraps nearly around the hinge pin (7) Any number of bands can be used in each direction to obtain the desired torque characteristics The novel friction hinge exhibits no lost motion and very slight spring-back

Friction hinge with selectively tightening bands

An inventive friction hinge (5) is provided which also provides detenting in a position or arcuate range. The friction torque is provided by a spring band (13, 65 or 73) which fits tightly about a shaft (11, 61 or 67) or within the cavity of a housing. Detenting is provided by features (21, 63 or 71) on the band and the mating part (19, 59 or 69) that cause the band to change shape when the features align. The detenting torque can be varied by changing the detailed shape of the features. Covers (3) that close, as on laptop computers, can be held shut by the use of the inventive detenting friction hinge which can also provide the friction needed to hold the screen of the computer in position during operation.
