DEFINITION

Classification: 52/79.7

(under subclass 79.1) Structure wherein each of two or more subenclosures is provided with an opening through one side thereof, such openings to mate with each other to form a passage for people from one subenclosure to the other.

(1) Note. An opening, for this subclass, may be the absence of an entire wall, in which case, each subenclosure would form half of a room.
