A female button is in an unlocked state when a rotator takes a first position and is in a locked state when the rotator takes a second position, insertion and removal of a post of a male button being allowed in the unlocked state, and insertion and removal of the post of the male button being hindered in the locked state. Arresting part or elastic member is provided with a projection which, when the rotator rotates toward the second position, displaces the arresting part toward the rotational axis before the rotator reaches the second position and, if the displacement of the arresting part toward the rotational axis is obstructed by the post, rotational resistance of the rotator is increased.

A snap button can include a snap button body and a fastener connected to the snap button body with a cloth interposed between them, wherein the snap button body includes a button member including a base; and a metal eyelet attached to an inner surface of the base, the inner surface being placed to face the cloth, wherein the button member includes an engaging portion provided on an outer surface opposite to the inner surface of the base, wherein the fastener includes a fastener base and a pin to be swaged, which protrudes from an inner surface of the fastener base, the inner surface being placed to face the cloth, and wherein the eyelet includes a cylindrical portion receiving the pin, the cloth being pierced by the pin, and the pin being swaged on the inner surface of the base of the button member.

A fastener element used to couple one or more items together, including layers of fabrics or other materials. The fastener element includes a top element having a central opening with a closed bottom surface adjoining a ring. On an underside of the ring is a protruding, piercing element that. The fastener element allows for more than two layers to be fastened together in a snap system and for a plurality of layers to be joined together. The fastener element can allow multiple layers to be joined together by coupling a first socket of a snap system to the top element and another socket to an underside of the ring and to the protruding piercing element. The fastener element can be used for multiple applications to secure more than one layer of fabric or another material together.

A clasp which has a primary body and a secondary body couples an elongated member. A bore has a groove within the primary body. A rod has a leg coupled to the secondary body and slidably engages the groove. A shaped locking channel is coupled to the groove. The leg engages with the shaped locking channel for coupling and decoupling the primary body with the secondary body.

A releasable interlocking device comprising a pair of interactive plates, for fastening to apparel utilizing a system of two interactive plates which when brought together utilizes the thickness of the apparel and stud of a male plate to engage through the lips of the female plate to snap fit and lock without damage to the aforesaid apparel.

A magnetic fastener system has a first fastener structure with a body with a first side and a second side. At least one of a male or female friction-snap fastener is positioned on the first side. A pocket is formed within the second side and a magnet is positioned therein. A recessed surface is formed in an interior of the pocket. A captive wall is formed around the recessed surface. The magnet is positioned between the first side and the recessed surface. A second fastener structure has a shape defined by an outer sidewall, wherein the shape of the outer sidewall substantially matches a shape defined by the captive wall, wherein second fastener structure is removably insertable into the pocket, and the first and second fastener structures are magnetically connectable. At least a third fastener structure is removably connectable to at least one of the male or the female friction-snap fastener.

A component connection has a first component, from which a fixing element protrudes, and a clamping element, which in a tightened rotating position is directly supported relative to the first component directly by way of the fixing element or is indirectly supported relative to the first component by way of a further component. The clamping element has a recess into which the fixing element protrudes from a lower side of the clamping element, wherein a seat portion of the recess is designed in the form of an ascending spiral staircase or thread and at least one free end of the fixing element reaches behind this seat portion in an interlocking manner, such that the at least one free end is seated on the seat portion and when the clamping element is in the tightened rotating position, presses against the seat portion.

A female member (1) of a snap fastener includes a main body (2) made of a metal and having a cylindrical tube portion (23) and a dish-shaped portion (22), a resin spring (3) housed in the main body (2), and a surface covering member (4) crimped onto the cylindrical tube portion (23). The resin spring (3) is a resin plate that can be housed in the main body (2), and the resin plate has a slot (35, 35A, 35B, 35C) at a central portion thereof. The cylindrical tube portion (23) has a support portion for the resin spring (3), and the resin spring (3, 3A, 3B, 3C) is fixed in position by the support portion.

A latch system has a socket assembly and a plug assembly. When the socket assembly is within a predetermined distance from the plug assembly, a socket magnet member and a plug magnet member displace the socket assembly towards the plug assembly. To place the latch system in an engaged configuration, the head portion of the plug member passes through a main opening in a socket housing and a plug opening in a socket plate such that the head portion is within the primary chamber. To place the latch system in a latched configuration, the socket assembly is displaced relative to the plug assembly to arrange at least a portion of the socket plate within a head gap defined by a head portion of a plug member.

A snap button includes a female snap body and a socket ring. The female snap body includes a bottom portion and a side wall rising from a peripheral edge of the bottom portion, the side wall provided with a holding portion for holding the socket ring. The socket ring includes a flange portion arranged radially outward and held by the holding portion and an engaging portion arranged radially inside the flange portion. The engaging portion protrudes downwardly toward the bottom portion side of the female snap body and below the flange portion, in the axial direction of the socket ring. An inner diameter of the socket ring may be gradually increased from an intermediate point in the axial direction of the engaging portion to one end and other end in the axial direction of the engaging portion. The engaging portion of the socket ring may be provided with a plurality of slits along the radial direction in the circumferential direction.
