A computer dock having a device for protecting a portable computer against
damage during vertical or inclined insertion within the computer dock.
The computer dock includes an abutment member, slidably mounted on a
rail, and biased to an upper position when the dock is not in use; the
abutment member moving downwardly as a result of abutment against a
portable computer during insertion, and at the same time exerting an
upward force that at least in part counteracts the downward force of
gravity acting on the portable computer.
