Shock-Isolating Casters for Shippability Protection
The use of shock-isolating casters enables simplification of packaging of
sensitive computer equipment.
This technique can be applied to a data processing apparatus package that
has little or no internal buffering against communication of
mechanical shocks to the package contents. For example, the apparatus 8
shown in Fig. 1 has a frame 10 which houses a logic unit 12 and a number of
integrated power/cooling units 14. Because of the small frame size and large
logic unit and also the rigid construction used in the frame, shock-inputs to the
frame are amplified. This is because there is little or no shock-absorbing
flexibility in the frame or in the mounting of the equipment elements in the frame.
The use of shock-isolating casters overcomes this problem. Casters 16
having coiled spring 18 (Fig. 2) mounted on frame 10. Mechanical shocks caused
in shipping or moving the apparatus are absorbed by the springs 18, which,
however, are stiff enough to hold the apparatus level in ordinary handling and
