Abstract: Disclosed is a device adapted to mount to a desk for use with a computer keyboard, a mouse, or a system such as a laptop computer. In one embodiment, the device includes a stationary bracket attachable to the desk, a main housing in sliding engagement with the stationary bracket, and a keyboard support tray connected to the main housing and adapted to support the keyboard or laptop computer. The device further includes a palm rest and an optional mouse support tray. The elevation of the keyboard support tray, palm rest, and mouse support tray may be independently adjusted. The keyboard and mouse support trays may also be independently tilted to achieve a comfortable working configuration. A locking member may also be provided to secure the housing and keyboard support tray in a stored position under the desk to prevent theft or computer system operation by unauthorized persons. An anti-pry feature may also be provided for additional security.

Abstract: The invention provides means to protect a widely used keyboard such as the IBM XT PC and PS/2 keyboard against vandalism and spill if such a keyboard is used in exposed situations, e.g. in self-service application/transaction machines which are publically accessible and unattended. On the base plate or housing 1 respectively of the keyboard 12 a grid plate 8 is fixed. This grid plate has openings 10 arranged in the pattern of the keys and in such a size that the cone-like keys 11 cannot be removed toward the top. The grid plate may be fixed directly to the keyboard housing or by means of a supporting frame 4 which is secured to the housing. In both cases grid plate or supporting frame respectively include a rim 5 to form a shallow trough 21 with the keyboard housing. A gasket 2 is provided between grid plate or supporting frame respectively and the keyboard housing. A drain 3 is provided in the rim to give controlled outflow.
