Class 402
BINDER DEVICE RELEASABLY ENGAGING APERTURE OR NOTCH OF SHEET
Class Definition:
This class is the residual locus for:
(1) A device including a sheet retainer* in the form of means
which passes through the thickness dimension of a sheet* or a
group of sheets to secure the same in either geometrically
congruent relation (see (1) Note below) or in haphazard
arrangement and cooperates with structure (e.g., hole,
peripheral incised opening, etc.) of the sheet(s) to
releasably retain such sheet(s) therein or thereto in such a
manner that removal thereof, in the manner intended, from the
means may be accomplished without mutilation (e.g., tearing,
deforming, etc.) of any portion of either the means or the
sheet(s).
(2) such sheet retainer, per se.
(3) a depository* or other perfecting feature intended for
attachment to and serving to perfect a sheet retainer* and
its proximate function as set forth under (1) above, or
(4) a sheet, per se, notched or apertured to accommodate a
sheet retainer of this class.
(1) Note. Such a device having structure limiting its use
to, or combined with sheets disposed in a particular
arrangement for exhibition (e.g., overlapped, side-by-side
arrangement, etc.) is classified elsewhere (see search notes
below referencing this note or see the appropriate container
class).
SCOPE OF THE CLASS
Class 402 is intended as the locus for devices and
subcombination thereof the proximate function of which is the
retention of sheets* by sheet retainer* means which passes
through the thickness dimension* of the sheets to releasably
retain the sheets. The subject matter for the most part
represents what is generally known as the loose-leaf binder
"art".
STRUCTURE OF THE CLASS
The first-line subclasses of the class are based on the mode
of operation of the sheet retainer*, where possible, with the
remainder of the subclasses based on the structure (generally
static) of the device.
Provided in this class are cross-reference art collections
based on disclosed use or particular characteristics as
indicated in the titles and definitions thereof. These
collections of disclosures are not exhaustive but are
intended as aids to a search based on ultimate function or
use, as a supplement to a search of other subclasses in this
class, or as an indication of further related fields of
search inside or outside this class.
GENERAL NOTES
This class (402) is restricted to the subject matter defined
above in this Class Definition. The definition set forth
above should, however, be read in the light of further
limitations imposed thereon by the other sections and by any
SEARCH CLASS notes in the subclass definitions.
Figure 1 appearing in connection with certain defined terms
in the Glossary is intended as an aid in comprehension of the
limitations of the concepts incorporated in such term in the
subclass titles and definitions. The details illustrated in
such figure are not to be considered as constituting a
structural limitation on the subject matter defined.
An asterisk (*) has been applied to certain terms throughout
this Class Definition to indicate that such terms have
specific limitations in this class as set forth in the
definitions of such terms in the Glossary, for which see.
Where such asterisk is employed in a subclass definition, it
will not be repeated in any subclass indented thereunder.

GLOSSARY:
DEPOSITORY
An article adapted to include a sheet retainer*, of this
class, for the retention of apertured sheets* and intended to
receive both (1) the nonthickness surface (See Fig. 1) and
(2) the thickness surface (See Fig. 1) of the sheet or either
(1) or (2) above.
KEEPER
An element or mechanism which cooperates with a sheet
retainer to releasably secure a sheet* thereon.
SHEET
A three dimensional body having all opposed surfaces thereof
disposed in substantially parallel relation each nonthickness
surface (See Figure 1 below) of which has a greater surface
area than the area of any one surface of the two remaining
pairs of opposed surfaces. [figure]
(1) Note. A composite sheet including means such as an
apertured or notched tab or strip attached thereto for
cooperation with a sheet retention means is considered the
equivalent of a one piece sheet likewise notched or
apertured. Note particularly subclass 500 for a device of
this class employed to releasably retain such composite
sheet.
(2) Note. A sheet-like body (e.g., "divider", "follower",
"sheet lifter", etc.) serving as a component of a device
(e.g., container, depository, etc.) will not be considered a
sheet as defined above. Such body is a component of the
device rather than a sheet intended for temporary storage on
or within the device.
SHEET RETAINER
an elongated element which passes through the thickness
dimension (See Figure 1 of the Glossary) of a sheet* or a
group of sheets to secure the same and cooperates with
structure (e.g., hole, peripheral incised opening, etc.) of
the sheet(s) to releasably retain such sheet(s) and may
further cooperate with (1) another elongated element or (2) a
keeper*, to so retain such sheet.
