Filed:

Feb 25, 2010

Appl. No.:

12/712911

Inventors:

Chris Linegar - Sydney, AU
Mark Norwalk - Austin TX, US

International Classification:

G06F 3/02
H03M 11/00

US Classification:

345168, 341 22

Abstract:

An adjustable ergonomic keyboard includes keyboard segments coupled by a joint allowing the keyboard segments to pivot relative to one another. A retainer secures a corresponding keyboard segment with respect to a base support and allows the corresponding retained keyboard segment to rotate thereabout and to travel laterally with respect to the base support. The base support may be part of a portable laptop chassis or body or may be a stand alone base for use of the keyboard as a peripheral data input device.

Inventors:

Chris Linegar - Sydney, AU
Mark Norwalk - Austin TX, US

International Classification:

G06F 3/02

US Classification:

345168

Abstract:

An adjustable keyboard having a number of keys is formed in at least two segments which are mutually movable relative- to one another using a hinge or joint. Each of the segments of the keyboard has keys mounted thereon. The adjustable nature of the keyboard reduces stress and discomfort to the user by reducing contortion to the user's wrists. More particularly, discomfort to the user caused by pronation of the wrists and/or ulnar deviation of the wrists is reduced. The hinge or joint is in the form of a ball and socket-type joint with a locking mechanism, which preferably includes a pivoted handle, in the form of a lever, used for locking and unlocking the hinge or joint. The surface of at least one of the ball and socket of the joint define a plurality of recesses or a plurality of projections, to provide increased resistance to joint movement.

Abstract:

An adjustable keyboard having a number of keys is formed in at least two segments which are mutually movable relative-to one another using a hinge or joint. Each of the segments of the keyboard has mounted thereon some of the keys. The adjustable nature of the keyboard reduces stress and discomfort to the user by reducing contortion to the user's wrists. More particularly, discomfort to the user caused by pronation of the wrists and/or ulnar deviation of the wrists is reduced. The hinge or joint is in the form of a ball and socket-type joint with a locking mechanism, which preferably includes a pivoted handle, in the form of a lever, used for locking and unlocking the hinge or joint. The surface of at least one of the ball and socket of the joint define a plurality of recesses or a plurality of projections, to provide increased resistance to joint movement.
