ABSTRACT:
A keyboard rest is made of resilient material such as foam, and has a sloping top surface for proper keyboard positioning. A resilient palm rest is provided adjacent the base of a received keyboard and acts as a stop to keep the keyboard properly positioned. The resilient keyboard rest member may be attached to a lap adapter comprising a generally rectangular base with a plurality of parallel flutes along its bottom, so as to provide air channels. Such structure limits lateral movement of the lap adapter when placed on the lap of a user, such as a computer operator or wheelchair patient. The alternating ribs and channels therebetween provide pressure dispersion while providing traction. The air channels provide air circulation. The keyboard rest member may be used without the lap adapter for use directly on a desktop or similar flat surface. Either embodiment provides enhanced ergonomic characteristics for the prevention of repetitive motion injuries and cumulative trauma disorders by reducing a user's physical stress of interacting with a keyboard or similar object.
