SECTION I - CLASS DEFINITION

This class provides for receptacles or enclosures, combined with article supporting means such as drawers, racks, shelves, etc., fixed or movable partly or wholly out of the enclosure to make the article supported more readily accessible, and enclosures combined with any nonreceptacle feature for which there is no other provision. This statement is intended to include receptacle structures having modified features to cooperate with the indicated combined devices.

Included in this class, for example, are article containing magazine type cabinet structures having means to facilitate the removal of articles therefrom, showcases, counters, outdoor type cabinets, cabinets designed for use in worship, sectional unit type cabinets, enclosures specially designed to house radios, television sets, phonographs, and picture machines and film. See Subclass References to the Current Class, below, for these subclasses.

The term "component" as used in the subclass titles and definitions relates to compartments, walls, doors, shelves, partitions, racks or other article supports, or similar parts of a compartment, fixed or removable.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

In general, except for article supports, etc., as set forth in the above class definition, instrumentalities provided for in other classes with an enclosure solely for housing the instrumentality are classified with the type of instrumentality.

Receptacle structure, per se, is not provided for herein. Such structures are in the appropriate receptacle classes of which Class 220, Receptacles, is the generic class. For the distribution of the receptacle art see the notes to the definition of Class 220.

SPECIAL USE TYPES AND COMBINATIONS OF WHICH A CABINET IS A PART:

A. Cabinets or enclosures specially designed to house radios, phonograph instruments or records, picture machines or film are found in this class. (See Subclass References to the Current Class, below.) The housed apparatus may be defined in general terms without the recitation of the characteristics of it or its particulars or relationship with the cabinets.

Cabinets in combination with apparatus such as loud-speakers, dials, tuning handles or shafts, chassis and so forth, are classified with the apparatus.

B. Cabinets designed solely for use in worship and cabinets designed specially for laboratory, dental, barber or medical use are in this class. (See Subclass References to the Current Class, below.)

See Reference to Other Classes, below, for related art areas.

CABINET SUBCOMBINATIONS

A. Closures and Doors.

Cabinets with doors and closures are found in the various subclasses providing for movable components depending upon the particular type of motion of the closure or door. See Subclass References to the Current Class below, for cabinets with inner and outer closures and those with a closure having an auxiliary opening. Arrangements of doors or closures on two or more sides of a cabinet are also provided for in this class. Folding cardboard type cabinets with sliding doors are provided for in this class.

B. Closure Fasteners and Locks:

With the exception of a few special types of locking and latching devices provided for in the subclasses of this class, such devices for movable cabinet parts have not been set out since they are of the types that can be adequately cross-referenced in Class 70 and Class 292. Also see Subclass References to the Current Class.

C. Guides for Drawers and Other Sliding Components:

Horizontally sliding cabinet drawers, shelves, closures, etc., provided with guide means are in this class. Other combinations of cabinet components and guide means therefor are classified in the subclass providing for the particular type of component. See Subclass References to the Current Class, below.

D. Handles:

Cabinets with carrying handles and those having both a carrying handle and a particular supporting means usable independently of the handle are found in this class. See Subclass References to the Current Class, below.

Movable cabinet components or parts provided with a handle mounted thereon and movable therewith as a unit. See Subclass References to the Current Class, below.

E. Operators:

Cabinet components or parts provided with power driven means are in this class. See Subclass References to the Current Class, below.

F. Panels and Walls:

This class is not concerned with wall or panel structure, per se, since such structures are provided for in other classes. See Subclass References to the Current Class, below for cabinets having walls of foraminous material and those with spaced walls or with insulation.

Also see References to Other Classes for related art areas.

G. Cabinet Supports:

Cabinet structures including supporting or mounting means for the cabinet are specifically provided for in this class. See Subclass references to the Current Class, below.

Outdoor type cabinets with wall or window mounting means and canopy or curtain type cabinets with wall mounting means.

Cabinet supporting means combined with any of the cabinets provided for in subclasses 3 to 241 are classified with the particular type of cabinet.

Also see References to Other Classes for related art areas.

H. Tables, Racks and Other Article Supports:

See Subclass References to the Current Class for the following: Cabinet structures associated with a leg supported table which can be removed from and used independently of the structure are classified in this class. See Subclass References to the Current Class for other cabinet combinations involving a table or shelf.

Movable racks and other article supports are found in substantially all of the subclasses involving movable components.

See Subclass References to the Current Class for show cases with racks, for cabinets with external racks or article supports, and for cabinets with fixed or merely removable racks or other article supports; for cabinets with supporting means for a typewriter, adding machine, dictaphone or sewing machine. Also see Subclass References to the Current Class for cabinet structure with means to support a supply of paper in position to be written on and for cabinets with means to support a book in position to be read.
