Class 403
JOINTS AND CONNECTIONS
Class Definition:
This is the generic class of connections between two or more
rigid or semirigid members at substantially a single locus
when (I) the members cooperate to form a utilitarian
structure or assemblage; (II) either (a) an intrinsic
property of at least one of the members is utilized in
effecting the connection, (b) the members are related to each
other in a particular manner (e.g., angularly), (c) a portion
of one member reorients relative to a portion of the other
member about the connection, or (d) all other connections
between such members for which no other provisions have been
made; and (III) the members constitute either (a) stock
elements having such general and varied utility as to be
identifiable with no particular art until connected (e.g.,
framework members which transmit force or torque to each
other), (b) components of an assemblage which have the same
utility before and after connecting but which, when
connected, interact with each other to accomplish a common
task and no longer have any independent operation (e.g.,
rigid, interconnected torque or thrust transmitting rods),
(c) subcomponents of an assemblage, at least one of which has
utility only when interacting with the other to accomplish a
specific task (e.g., windshield wiper and windshield), or (d)
components having independent utility, but which, when
connected, cooperate to change, enhance, expand or make
interdependent their operation (e.g., articulated members).
This is also the generic class of connections between the
ends of a single rigid or semirigid member at substantially a
single locus when (I) the connected member forms a
utilitarian structure or assemblage; (II) either (a) an
intrinsic property of the member is utilized in effecting the
connection, (b) the ends of the member are related to each
other in a particular manner (e.g., lapped), (c) portions of
the member reorient relative to each other about the
connection, or (d) a tool driven, tool deformed, or
destructively releasable fastening means is utilized; and
(III) the member constitutes either (a) a stock element
having such general utility as to be identifiable with no
particular art until connected or (b) a component of a larger
assemblage which component has the same utility before and
after connection, but which when connected accomplishes its
task in a varied manner.
This is also the generic class of connections between a
flaccid member (e.g., cable) and a rigid or semirigid member
at substantially a single locus when (I) the connected
members form a utilitarian structure or assemblage, and (II)
in effecting the connection either (a) an intrinsic property
of the member is utilized or (b) a tool driven, tool
deformed, or destructively releasable (i.e., the only method
of releasing it is to destroy it) fastening means is
utilized.
In addition, this is the generic class for connecting or
fastening means, per se, when the means is (I) disclosed as
used solely with a connection proper for this class and (II)
limited by either its structure (e.g., an L-shaped nail
plate) or configuration (e.g., multiple fasteners in a
specific pattern) to a very restricted range of use (i.e.,
the means lacks general utility).
(1) Note. The term "member" as used in this class refers to
the primary members which are connected and each may consist
of one part or a plurality of parts. Many connections
involve the use of a plurality of elements each of which may
be connected to a member or to another element. However,
unless each of the connections involved is coordinate with
the others in the system, the elements are not referred to as
"members" but as "components". For example, a bolt
connecting two abutting members bridging the juncture of two
packed members is not considered a member, but a bolt
independently joined to each of two spaced members is itself
a member. Likewise, a plurality of bolts joining the same
two members at the same locus are not members but
components.
(2) Note. The expression "utilitarian structure or
assemblage" denotes an entity which has a function and
identity of its own apart from that of its individual
members. Connections between members which, when connected,
do not form a utilitarian device but which are connected
merely for convenience or storage are not classified in this
class (403). See Lines With Other Classes and Within This
Class, below, for the appropriate classification.
(3) Note. Patents issued prior to 1931 have not in all
instances been classified by their claimed disclosure, so the
placement of these older patents does not necessarily
indicate lines of classification.
(4) Note. A claim which recites only as much of the
structure of a member as is necessary to effect its
connection may be included within this class, and, in
general, the mere naming of a member will not cause
classification outside this class. However, if details of a
member which go beyond those which are used in effecting the
connection are included, classification will be based on the
member unless specific provision is made in this class (403).
In the situation of a single member with connected ends, the
broad recitation of a "loop" or equivalent terminology will
not cause classification outside this class, since such
configuration is necessary to align the ends to effect their
connection. However, a single member and means connecting
its ends which allow the size of the closed member (i.e.,
loop) to be adjusted, are elsewhere classifiable.
(5) Note. In interpreting this definition, the following
examples of intrinsic properties are given: (A) a
modification, (e.g., threading) of at least one portion of a
member at its connection point for other than mere reception
of a fastener; (B) a particular shape or cross-section of at
least one portion of a member at its connection point; and
(C) a physical or chemical property of a member which has an
effect on the connection either before or after the
connection is effected, (e.g., fusion, affinity for certain
adhesives, resistance to electrolytic action, flexibility,
etc).
(6) Note. The expression "utilitarian structure or
assemblage" denotes an entity which has a function and
identity of its own apart from that of its individual
elements and subcomponents of such entity. Connections
between elements which, when connected, do not form a
utilitarian device but which are connected merely for
convenience or storage are not classified in this class (403)
but will be formed in the appropriate class which provides
for the particular assemblage.
(7) Note. If otherwise proper for this class, a connection
between two ends of a single member wherein no structure of
the member which is not necessary to effect the connection
will be placed in this class unless specific provision is
made elsewhere. Inventions which include any structure of the
member other than that necessary to effect the connection
will be classified with the member or in a more general
class. The broad recitation of a "loop" or equivalent
terminology will not cause classification outside this class
(403) since such configuration is necessary to align the ends
(i.e., to effect the connection). See References to Other
Classes, below.
