Abstract
Low profile portable information handling systems rotationally couple a lid and chassis portion with a dual axis hinge that couples at one axis with an extension and countersink engagement to enhance system strength. For example, a conical boss in a lid support frame extends into a countersink formed in a hinge axis and includes threads to accept a screw inserted from the hinge axis into the conical boss. The conical boss inner diameter extends the space available for placement of threads to engage a screw to provide enhanced coupling strength between the hinge axis and lid support frame.
Claims20
An information handling system comprising:
- a chassis having a hinge support frame;
- a lid having a hinge support frame;
- processing components disposed in the chassis and operable to cooperate to process information;
- a display disposed in the lid and interfaced with the processing components, the display operable to present information as visual images;
- a hinge coupled to the chassis hinge support frame and the lid hinge support frame by one or more coupling devices, the hinge rotationally coupling the chassis and lid to each other;
- wherein the lid support frame has a conical boss extending into a countersink of the hinge at the coupling device.
A method for coupling a hinge to an information handling system, the method comprising:
- forming an opening in the hinge to accept a coupling device;
- forming a countersink in the hinge opening;
- forming an opening in the information handling system to accept the coupling device, the opening having a securing device for engaging the coupling device;
- forming an extension integrated with the information handling system proximate the opening and sized to fit into the countersink, the extension including the securing device for engaging the coupling device;
- and
- inserting the coupling device into the hinge opening then into the extension and then into the information handling system opening, the coupling device engaging the securing device to couple the hinge to the information handling system.
A system for rotationally coupling an information handling system chassis and lid, the system comprising:
- a dual axis hinge having first and second arms, the first arm having a coupling device opening;
- a lid securing surface proportioned to rest against the first arm and having a coupling device opening aligned with the with first arm coupling device opening;
- an extension disposed at the lid securing surface opening to extend into the first arm coupling device opening when the lid securing surface rests against the first arm;
- and
- a coupling device inserted from the first arm coupling device opening into the lid securing surface coupling device opening to engage with the extension for securing the lid to the hinge first arm.
