Computer keyboard assembly with exchangeable wrist support

摘要

A computer keyboard assembly includes a keyboard and a wrist support which is releasably mounted to the keyboard by a retention device. The retention device includes a slide movably received in a slot defined in a front extension of the keyboard. The slide has an L-shaped top projection defining a channel. A guide plate is fixed to the front extension of the keyboard by a bolt and has an edge movably received in the channel for retaining the slide in the slot and guiding the movement of the slide. A pawl is formed on the slide to be movable therewith between a released position and a secured position. The slide is biased by a spring a toward the secured position where the pawl engages a U-shaped member formed on an underside of the wrist support thereby securing the wrist support to the keyboard. A notch is defined in a bottom face of the slide for manually moving the slide against the spring toward the released position where the pawl disengages from the U-shaped member of the wrist support for releasing the wrist support from the keyboard.
