Abstract: A hinge for notebook computers is disclosed which includes a cam mechanism to keep the lid closed when the computer is not in use and a cooperatively operating friction mechanism to maintain the lid's position when in use. The friction mechanism operates in conjunction with the cam mechanism to enhance the operational characteristics thereof. Previous attempts at cam hinges for laptops demanded that the cam mechanism, which provides torque in opposition to the frictional torque as the lid nears the closed position, be capable of overwhelming the friction mechanism in order to perform its intended function. This placed a strain on the cam mechanism, resulting in the need for a stronger heavier hinge, and stronger heavier attachment points in the laptop. By controlling the magnitude of the friction by substantially reducing it at the moment of cam engagement, the cam hinge becomes a far more practical device.

Abstract: In a frictional hinge device a support block 20 is molded in a synthetic resin around the metallic shaft 10 so that the support block 20 is rotatably supported by the metallic shaft 10. The support block 20 is held at any angles by a surface friction resistance between the support block 20 and the metallic shaft 10. The synthetic resin has a modulus of bending elasticity, a changing rate of which is up to 30% at an operating temperature ranging from −20 to 80° C. The support block 20 tightly engages with the metallic shaft 10 due to a residual stress appeared between the support block 20 and the metallic shaft 10 when cooling the synthetic resin to shrink. Due to the smaller changing rate of the modulus of bending elasticity, the surface friction resistance becomes stable between the support block 20 and the metallic shaft 10 under normal ambient temperature with the least amount of friction.

Abstract: In a frictional hinge device, an inequable strain distribution within a synthetic resin is determined to be 15% or less so as to increase a torque holding rate by 80% or more to tightly engage a support block 20 with a metallic shaft 10. This eliminates variations on a frictional torque with no substantial stickslip phenomenon, abnormal noise and initial scratches accompanied when pivotally moving the support block 20 relative to the metallic shaft 10 so as to maintain a stable surface friction resistance with good endurance for a long period of time.

Abstract: A hinge engages a cam such that the hinge first rotates relative to the cam, then linearly engages the cam. Preferably, the hinge includes a guiding post that rides along a raised arched surface on the cam during the rotary motion of the hinge.

In a preferred embodiment, one or more cams are mounted on a receiving structure and one or more hinges are mounted in corresponding locations on a detaching structure, where said detaching structure is physically separable from the receiving structure. Engagement between the one or more cams and the one or more corresponding hinges allows the detaching structure to first rotate relative to, then linearly engage, the receiving structure, providing for reliable blind mating between connectors on the detaching structure and connectors on the receiving structure.

Abstract: In order to achieve the situation where a pivotably mounted structural part, under the action of an adjusting force, is made to move indeed automatically but merely with braking and damping action, and thus at a reduced speed and with reduced kinetic energy, provision is made for the hinge which mounts the structural part to be equipped with a pivot brake, of which the braking force applied over the pivoting distance is smaller than the adjusting force and is adapted to the progression of the adjusting force over the pivoting distance. In selected regions, the braking force of the pivot brake may be greater than the adjusting force, in order to retain the structural part in these regions. The braking work performed by the pivot brake is advantageously calculated so as to absorb 20% to 25% of the adjusting work performed by the adjusting force.
