Abstract:
A pivot hinge has a first stem, a second stem and a sleeve. The first and second stems respectively have a body with through holes adapted to be engaged with a surface, and an extension with grooves formed on a periphery of the extension. The sleeve is hollow to respectively receive therein the extensions of the first and second stems and has a cutout longitudinally defined in an outer periphery of the sleeve and a pair of gaps radially defined in the periphery of the sleeve to communicate with the cutout.
Abstract:
A compound hinge system includes a first link and a second link. The first link includes knuckles and arcing engaging surfaces next to stop portions that are configured for receiving engaging lug portions on a second link member. A second link member includes first and second sets of knuckles. One of the sets of knuckles cooperates with a hinged pin to pivot relative to the first link while the second set of knuckles receives a hinge pin to pivot relative to the second element. The lugs slide relative to the engaging surface and push against the stop portions to flex them outward and require additional force to move between various stops in the range of motion.
Abstract:
A hinge comprising a first hinge attachment member; a second hinge attachment member, the first and second hinge attachment members being movable relative to each other; and a coupling member for coupling the first and second hinge attachment members and for supplying damping when the first and second attachment members are displaced relative to each other. The damping is comprised of surface effect damping and such damping may be direction dependent or dependent on the rate of displacement or acceleration of one of the members. The hinge includes means for adjusting the magnitude of the damping supplied.
Abstract:
A free positioning hinge is especially used to a notebook computer, an electronic dictionary, a personal digital assistant, etc. for opening covers of these devices, or is used to a rear view mirror of a car. The free positioning hinge is formed by pivotally engaging a rotary shaft with a sleeve. The sleeve is formed by a plurality of stacking closed pads. Each pad has an axial hole. A hollow neck extends from the axial hole and two hollow shoulders are extended from the neck, thereby, two flexible arm portions being formed between the axial hole, the two shoulders, and the neck. The friction surface of the sleeve has a preferred flexibility so that it is difficult to damage the components assembled thereto. Furthermore, oil stored in the holes may provide a proper lubrication ability so as to prolong the lifetime of the device.
Abstract:
A clip-type friction hinge device comprises a hinge body having insertion grooves on both insides thereof, a shaft being inserted to the each insertion groove of the hinge body on one side thereof and defining a central shaft when a monitor is pivotally moved, stands being formed on the outer circumference of other side of the shaft to be rotated about the shaft, clips each being inserted between the stand and the outer circumference of the shaft to adjust the amount of torque during the rotation of the stand, and torsion springs being fixedly installed on both outer circumferences of the hinge body to elastically support the stands relative to rotation of the stand.
Abstract:
A compound dual unidirectional friction hinge comprises a pivot pin and two rotary members fastened toward the same direction and being pivotally engaged with the pivot pin. The rotary members have respectively a fastening section and a pivot barrel connecting to the fastening section and pivotally engaging with the pivot pin. The pivot barrel has an edge at one end thereof to form an action gap with the juncture of the fastening section and pivot barrel. When either one of the rotary members is turned, the action gap of the rotary member becomes an open state while the action gap of the non-turning rotary member becomes a closed state and grips the pivot pin thereby to form the unidirectional friction hinge fastened toward the same direction.
Abstract:
A free-positioning hinge includes a rotary shaft and a sleeve. The free-positioning hinge is suitable to be used in an open-able device. The sleeve is formed by a plurality of equilateral triangular sheets which are stacked one by one. The center portion of each side of each triangular sheet is extended with a tongue. The center of the triangular sheets is formed as a round main axial hole having a diameter approximately equal to that of the rotary shaft. Furthermore, at each apex of each triangular sheet aside the main axial hole is disposed with a semi-circular sub-hole so as to increase the flexibility of the equilateral triangular sheets. Therefore, oil stored in the sub-holes can be supplemented to the friction surface between the sleeve and the rotary shaft so as to retain in a lubricating condition.
Abstract:
A shaft part (3A) of a second hinge member (3) is press-fitted into a support hole (23) of a first hinge member (2). By this, frictional resistance is generated between an inner peripheral surface of the support hole (23) and an outer peripheral surface of the shaft part (3A). A coiled spring (4) is disposed between the first hinge member (2) and the second hinge member (3). The coiled spring (4) biases the first and second hinge members (2, 3) such that when the first and second hinge members (2, 3) are turned in normal and reverse directions from a predetermined neutral position, the first and second hinge members (2, 3) are returned towards the neutral position side.
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:
The present invention relates to a clip type friction hinge device, which can be conveniently assembled and can freely adjust the torque to a desired rotary direction. The clip type friction hinge device of the present invention comprises a housing having an axial hole and a fixing slit formed at a lower portion of the axial hole; a rotary axis which is inserted to the housing to be rotatable; a torsion spring which elastically supports the rotary axis for the housing and is comprised of a pair of semi-cylindrical spring members; and a plurality of C type clips which are elastically inserted to the outer circumference of the torsion spring.
