An adjustment buckle assembly includes a first component having a shaft extending from a flange and a second component having a receptacle formed through a base. The shaft is configured to be at least partially inserted into the receptacle and tapers inwardly relative to a central axis extending centrally through the first component. The shaft carries a plurality of teeth that are configured to engage with a plurality of ribs carried on the second component.

Provided is a cam buckle including a body having at least one slot, and a cam arm movably coupled to and pivotable relative to the body. The cam arm has teeth for engaging a webbing and at least one boss for engaging the at least one slot. The cam arm is biased in an unlocked position where the teeth are configured to engage the webbing, and the cam arm is movable to a locked position where the teeth are configured to be disengaged from the webbing and the at least one boss is held in the at least one slot.

A mask according to an embodiment of the present disclosure includes: a filtering structure configured to perform an air filtering function; a buckle portion coupled to the filtering structure; and a strap connected to the buckle portion and worn on a body of a user, wherein the buckle portion includes: a body coupled to the filtering structure and having openings formed on both sides thereof; and a fixing piece having one side hinged to a sidewall of the opening and gripping the strap, wherein the strap is inserted between a side surface of the fixing piece and a side-wall of the opening to surround at least a part of an outer surface of the fixing piece, and slidably moves in one direction or both directions in the buckle portion selectively according to a shape of surrounding the fixing piece.

A buckle can include a first strap engaging device and a second strap engaging device. The first strap engaging device can include a first engaging structure extending rearward from the front portion, with the first engaging structure defining a first hole through a first surface of the first engaging structure that faces outward in a first side direction from the buckle. The first engaging device can also include a buckle protrusion configured to press against a first strap end extending through the first hole to engage the first strap end without the buckle protrusion extending through the first strap end. The second engaging device can be configured to engage a second strap end. A technique can include securing first and second strap ends using a buckle, which can include engaging the first strap end using a buckle protrusion without the buckle protrusion extending through the first strap end.

A buckle has a main body, a strap retaining bar connected to the main body, two locking legs formed as separate pieces from the main body and pivotably connected to the main body; and a spring formed of two L-shaped sections disposed between the two locking legs. The spring is attached to both of the locking legs, and exerts a force against the locking legs when they are pressed inward toward each other. The spring keeps the locking legs in an outwardly tensioned position, but does not let the legs flex outwardly in an unlimited manner, since the spring is directly connected to the legs. The spring allows the main body and locking legs to be formed of an inflexible material, such as metal. The locking legs are separate pieces from the main body and are connected to the main body via a pivot pin or other hinged mechanism.

Disclosed is a clip for managing laundry items, the clip having front and rear arms flexibly joined by an elbow and shaped to form an internal loop. The front arm terminates in a dogleg shaped to minimize catching on fabric, and the rear arm terminates in a tongue shaped to ease the clip onto fabric. The dogleg and tongue angle away from an opening to accommodate fabric and guide it into a gap between the arms. The elbow flexibly holds the arms apart to form the gap, which can expand to accept the fabric and hold it in place. The arms also include teeth to improve friction between the fabric and the clip. Also disclosed is method of using a system of laundry clips to improve laundry results, including folding a laundry item lengthwise and attaching a plurality of laundry clips on the item to hold loose sides in place.
