Abstract
A pivotal hinge of which the axial elastic force may be adjusted through elastic pads is disclosed. The pivotal hinge comprises a pivotal member, a positioning bracket, a pivotal bracket and at least one elastic pad. Due to the adjustable axial elastic force, the frictional pivot contact between the positioning and pivotal brackets may be varied.

A pivotal hinge for pivoting between a main unit and an LCD display, comprising:
- a pivotal member having a shaft member extending along an axis, wherein the shaft member comprises at least one non-pivotal structure for preventing rotation;
- the pivotal member being mounted to one of the main unit and the LCD display by a positioning element, the first swinging arm being rotatably passed by the shaft member;
- at least one slitting conical elastic pad passing through the shaft member to provide an axial elastic force thereto, said at least one slitting conical elastic pad extending helically into an open ring with a slit defined by two ends of the slitting conical elastic pad, said pad shaping into a conical configuration which inclines from its inner diameter to outer diameter at a conical angle;
- and
- wherein a free end of the shaft member is secured by a fastening member which is adaptable to adjust said axial elastic force.
A pivotal hinge for pivoting between a main unit and an LCD display, comprising:
- a pivotal member having a mounting part and a shaft member extending along an axis, wherein the mounting part is mounted to the main unit and the shafting member comprises at east one non-pivotal structure for non-pivotal coupling;
- a pivotal bracket comprising a mounting part and a first receiving portion, wherein the mounting part is mounted to the LCD display and the first receiving portion allows the shaft member to pass therethrough and to be supported thereby;
- at least one friction member, said at least one friction member being mounted to and passed by the shaft member and engageable with said non-pivotal structure;
- at least one slitting conical elastic pad passing through the shaft member to provide an axial elastic force thereto, said at least one slitting conical elastic pad extending helically into an open ring with a slit defined by two ends of the slitting conical elastic pad, said pad shaping into a conical configuration which inclines from its inner diameter to outer diameter at a conical angle;
- and
- wherein a free end of the shaft member is secured by a fastening member which is adaptable to adjust said axial elastic force.
A slitting conical elastic pad generally extending helically into an open ring with a slit, wherein the slitting conical elastic pad has two ends to define said slit and shapes into a conical configuration which inclines from its inner diameter to outer diameter at a conical angle.
A process of manufacturing a slitting conical elastic pads, comprising the steps of:
- a) preparing a wire material;
- b) subjecting the wire material to a drawing step under normal temperature then to a rolling step so as to obtain a drawn wire with a generally square cross section;
- c) curling the drawn and rolled wire helically similar to the shaping of a helical spring while simultaneously shaping the surface of the drawn and rolled wire with a conical angle under the aid of a jig during curling;
- and
- d) subjecting the curled wire to a laser-cutting step to cut the curled wire into an open ring-shaped segments so as to obtain conical elastic pads.
