A44B

BUTTONS, PINS, BUCKLES, SLIDE FASTENERS, OR THE LIKE (fastenings specially adapted for footwear A43C)

Introduced: September 1968

Description

A44B covers fastening devices and closures primarily used in clothing and textiles. This subclass includes buttons (of various materials and designs), pins, buckles, hooks, eyelets, and slide fasteners (zippers). It encompasses both the mechanical devices themselves and their manufacturing or application methods, covering traditional and innovative fastening solutions for garments, footwear, and fabric articles. Adjacent classes A44C (haberdashery articles) and A44F (corset components) address related but distinct accessory categories.

Glossary

Button Buttons A hand manipulated fastener that includes a rigid or semirigid portion (i.e. button) which is attached (e.g. sewn) to the structure it is intended to fasten or secure (e.g. clothing) in a manner that allows its reorientation by either movement about its attachment or movement of the structure it secures. A button is intended to be used with a complementary opening having a flaccid portion (e.g. buttonholes, looped cords) that forms the second essential part of the fastener. Buckle Buckles A hand manipulated fastener including engaging or holding means and structure for guiding during fastening, which can selectively hold a cooperating strap or belt that is either the structure secured (e.g. end of a dress belt) or a second portion of the fastener (e.g. securing strap of a backpack flap). Pin Pins A hand manipulated fastener that includes both (1) a portion specifically shaped (e.g. pointed) to facilitate impaling of and penetration into the structure fastened or secured and (2) a remaining portion (e.g. head) intended to be manually pushed on that does not penetrate the structure fastened or secured. Slide fastener Slide fasteners A hand manipulated fastener that includes (1) two, opposed, elongated, configured surfaces that are each attached by mounting means to a secured structure and are intended to directly contact and interlock with each other when fastened and (2) a sliding device that is much shorter in length than the surfaces and which travels along their length to forcibly shift them into or out of interlocking engagement.
