DEFINITION

Classification: 52/578

(under the class definition) Structure including plural modular or panel units connected by means lying between their major exposed faces by (1) a discrete fastener which differs in material and shape from that of the units or (2) units with configuration on one face or edge shaped for interfitting or keying with a mating configuration on an opposed adjacent unit or (3) a unit, per se, with a feature specialized to (1) or (2).

SEE OR SEARCH THIS CLASS, SUBCLASS:

415+, for facers bonded by a settable material section, e.g., brick and mortar wall which may have interfitting sections.

459+, for a construction utilizing a bridger strip over a panel juncture.

474+, for a panel interfitting with a shaft.

506.01+, for a construction wherein a facer is attached to a disparate structure.

519+, for lapped multiplanar interfitted sections forming a surface. 561+, for a construction of laterally related individually assembled courses.

574, for a construction of alternating reversed identical form modules.

596+, and 613+, for an opaque stone-like module or a composite panel which may include an edge feature which could be used to interengage another module but which is not critically defined for such use, particularly subclass 604 for one module usually facially related to another.

660+, for fabric or lattice-like open work, particularly subclass 663 for such a construction wherein annuli-members are arranged in a coplanar relationship.
