DEFINITION

Classification: 24/442

INCLUDING READILY DISSOCIABLE FASTENER HAVING NUMEROUS, PROTRUDING, UNITARY FILAMENTS RANDOMLY INTERLOCKING WITH, AND SIMULTANEOUSLY MOVING TOWARDS, MATING STRUCTURE (E.G., "VELCRO "):

(under the class definition) Subject matter including means (1) for securing a segment of the structure-to-be-secured* to either supporting structure therefor or a distinct segment thereof in a manner allowing the securement to be quickly detached, and (2) having a multiplicity of individual threadlike (i.e., the size of a cross-sectional area thereof taken perpendicular to its longitudinal axis being extremely small when compared to the area of the common mounting surface for the members) members which (a) each have all of their components integral with or fixedly attached to one another (b) are mounted to a common mounting surface anchored to the structure-to-be-secured* or a support structure therefor from which they extend upwardly, and (c) are intended to move both without preorientation and in unison towards engagement with separate, opposed structure attached to, formed from, or consisting of the distinct segment of the structure-to-be-secured* or the support structure therefor with which each threadlike member individually and mechanically interlocks (i.e., its movement is restricted in the direction in which force is transmitted thereto by the structure-to-be-secured*) to complete the securement.

(1) Note. To be proper for this and the indented subclasses several of the threadlike members should, by disclosure, be mounted along each side of the common mounting surface to allow random alignment of the means with the opposed structure at any given orientation of the mounting surface.

(2) Note. Patents which claim only structure details of a single, interlocking, threadlike member which is solely disclosed as being utilized in a securing means proper for this and the indented subclasses have been placed in these subclasses on a disclosure basis.

(3) Note. See the class definition for patent placement procedure.

(4) Note. Pointed or barbed threadlike members which pierce the unmodified surface of the structure-to-be-secured* or a support therefor to complete the securement operation are considered proper for this and the indented subclasses.

(5) Note. The trademark "VEL-CRO " has simply been used in the title of this subclass as an example of one well known fastener brand which generally fits within the broader concept of this subclass and has been both capitalized and placed between quotation marks in the title to protect its status as an active trademark.
