DEFINITION

Classification: 33/350

(under subclass 300) Device having added thereto means to shelter all or part thereof, to cushion the device as a whole, or to otherwise protect the device from physical damage.

(1) Note. Included in this subclass are such things as storage casings and covers and shock absorbing work attaching means. Shock absorbing features within the device, such as fluid supported direction sensors (see subclasses 327, 346+, 364, and 396), have not been placed here since they affect the device in its use and are thus an essential part thereof rather than being combined therewith.
