Electronic device and magnetic latching mechanism therefore

Abstract

A magnetic latch for a display of a laptop computer is disclosed. The latch uses magnetic attraction to maintain the display closed and uses magnetic repelling forces to pop-up the display when opened. The latch includes one or more magnetic elements in the body of the laptop and at least one magnetic element in the display. When the display is closed, the magnet element in the display is positioned adjacent the magnet element in the body having an opposite polarity so that the magnet elements are attracted to one another. To pop-up the display, the user moves the magnetic element in the display so that it meets the magnetic pole in the body having the same polarity. When these meet, the repelling force between them causes the display to open slightly so that a user can then readily open the display.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. application Ser. No. 11 / 302,907, filed 13 Dec. 2005, which is incorporated herein by reference, to which priority is claimed, and which was filed concurrently with U.S. patent application Ser. No. 11 / 302,801, which is incorporated herein by reference in its entirety.FIELD OF THE DISCLOSURE[0002]The subject matter of the present disclosure generally relates to a latch for a laptop computer and more particularly relates to a magnetic latch for a laptop computer that uses magnetic attraction to keep the display closed and uses magnetic repulsion to pop-up the display for opening.BACKGROUND OF THE DISCLOSURE[0003]Laptop or network computers have a body housing internal components and have a display attached to the body. The display is typically hinged to the body so that the display can be opened and closed relative to the body. In the past, mechanical latches have been used on laptop displays to mai...

AI Technical Summary

Problems solved by technology

Unfortunately, several structural issues with prior art hook and catch interlocks and counterbalance clutches pose problems for designers of laptop computers.

Although these prior art mechanisms are effective, they are susceptible to breakage.

For example, a hook, catch, or spring of a latch mechanism can break simply through use, rendering the display incapable of being locked closed.

If a hinge between a display and a body has been slightly damaged, portions of a latch mechanism may be misaligned and not work properly.

In addition, portions of the latch mechanism such as the hook may be exposed on the display or the body after opening and can be broken inadvertently.

Likewise, structural issues with prior art counterbalance clutches pose problems for laptop designers.

Thus, the clutches have built in stresses that can cause failure over time.

These clutches can also be damaged if the display is inadvertently moved relative to the body in unwanted directions.

For example, when the display is closed and the clutches are loaded, any injury to the hinge area by dropping the laptop can damage the clutch and / or hinges.
