Click here for a printable version of this file

SECTION I - CLASS DEFINITION

This class provides for devices which carry the weight of an article or articles or otherwise hold or steady it or them against the pull of gravity, and devices for holding an article to its support, which are not otherwise provided for.

(1) Note. Devices having structural features limiting them to use in a particular art remain with the art.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

LINE BETWEEN CLASS 248, AND CLASS 362, CLASS 313/39, AND CLASS 431

The line between this class and Classes 362, Illumination, 313, Electric Lamp and Discharge Devices, subclass 39, and 431, Combustion is as follows:

Class 223, Apparel Apparatus, subclass 120 for supports, bases and stands claimed in connection with means for making, repairing or maintaining in condition articles of apparel.

Class 362 takes any combination of a support with significant structure of the light distributing means or the combination of the light distributing and generating means.

Class 313, subclasses 49+ is the generic class for the combination of a support with significant structure of an electric space discharge device. See Lines With Other Classes, "Combined with a Support" of the class definition for the other classes which provide for the combination of a support and a discharge device.

The mere supporting structure goes to Class 248 and such supporting structure may include conduits for fuel or energy and mere cut-offs therefor. Supporting structures limited to use with lighting devices are in Class 362. Supports for a light generating device are in Class 248 unless a significant structure of the light generator is claimed, in which case it goes to Class 431 or Class 362.

The mere naming of a light or discharge device as the thing supported will not operate to take the case out of Class 248. If the support is in itself an essential part of the lamp or discharge device such as are many lamp bases, it remains in the art class. In Class 313, class definition, see the following sections of Lines With Other Classes: "Combined with Electrical Connector Structure,...(3) Electrodes Combined with Connector Structure"; and see "Envelopes, Casings, and Jackets for Lamps and Discharge Devices,...(1) With Attached Base" for the classification of an envelope with a base attached thereto.

LINES BETWEEN CLASSES 313, 248, AND 174

See Class 313, Electric Lamp and Discharge Devices, subclasses 49+ for electric space discharge devices in combination with a mere supporting means therefor. See subclasses 238+ which provide for electric lamp and discharge devices which have supporting or spacing structure for the electrodes or shielding members thereof. See Class 248, subclass 50, which provides for supports for elongated discharge or lamp tubes (e.g., neon) where no electrical features are involved. See Class 174, Electricity: Conductors and Insulators, subclass 138 which provides for insulated supports for neon and similar elongated tubular lamps where the support includes no structure limiting the device to use with electric lamps. Also, see paragraph 1 of Lines With Other Classes and Within This Class, above.

LINE BETWEEN CLASS 211 AND CLASS 248

Class 211 is a specific class under the class definition of this class (248). In general, Class 211 is the generic support class for plural articles and Class 248 is the generic support class for single articles. However, Class 248, subclasses 235 - 250, inclusive, subclasses 309.1 -316.7, inclusive, subclasses 500 - 509, inclusive, and subclasses 511 - 541 inclusive, additionally provide for supports of plural devices of the same (i.e., nondiverse) nature, and any of the subclasses in this class (248) will take plural diverse supports where one of the supported devices is ancillary to the main device supported (e.g., check, label and tag holders combined with an article support); while in Class 211 additionally provides for supports for single articles.
