Abstract: A buckle assembly has two buckle portions, each having a base body with a fastening hook and a fastening recess, and a magnet connected to the interior surface. The buckle portions are configured such that placing the interior surface of one buckle portion against the interior surface of the other buckle portion causes the magnets to engage each other and the fastening hook of each buckle portion to enter the fastening recess of the other buckle portion, to lock the two buckle portions together and prevent disengagement under tension in opposing directions parallel to a longitudinal extent of the buckle assembly. There is a fastening tenon connected to the base body and extending into the fastening recess on each of the buckle portions. The fastening hooks engage a respective one of the fastening tenons as the fastening hooks enter the fastening recesses to lock the two buckle portions together.

Abstract: A buckle assembly formed of a male buckle portion and a female buckle portion. The female buckle portion has a top wall, a bottom wall, side walls, and a cavity between the top wall and the bottom wall and a locking slot in each of the side walls. The male buckle portion has a base, two locking legs, a center leg, and two intermediate legs between the locking legs and the center leg. The locking legs extend through the locking slots in the female portion, and locking pawls at the end of the locking legs engage the edges of the locking slots to secure the buckle portions together. Each locking leg is connected to a flexible retaining member that prevents the locking legs from being flexed outwardly beyond a predetermined point. The intermediate legs and/or the retaining members form stop surfaces that prevent the locking legs from being flexed inwardly beyond a point of contact with the stop surfaces.

The male buckle portion has a base, two locking legs and two intermediate legs between the locking legs. The locking legs extend through the locking slots in the female portion, and locking pawls at the end of the locking legs engage the edges of the locking slots to secure the buckle portions together. The free ends of the locking legs are connected to the free ends of the intermediate legs by a retaining member, so that forces acting on the locking legs are transferred to the intermediate legs by the retaining members.

Abstract: A securing device that allows adjustable securing of a face mask, face shield or goggles to a wearer's head is formed from a first portion having a strap, a first end with a securing button and a connecting element, and a second portion having a strap, a first end with a securing button and a connecting receptacle for interacting with the connecting element to connect the two straps together. The securing buttons are formed from a top plate connected to a bottom plate via a connecting leg having a cross section with an acute angle. The bottom plate has slits extending from an outer edge to the connecting leg on both sides of the acute angle, such that a cord is securable to the securing button by inserting the cord into one of the slits, wrapping the cord around the acute angle of the connecting leg and exiting from the other of the slits.

Abstract: 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.

Abstract: A buckle assembly has a first buckle portion that cooperates with a second buckle portion. Each of the buckle portions has a base body with exterior surfaces, interior surfaces that extend from a central circular flat, a fastening hook on one longitudinal end and a fastening opening with a first fastening wedge on another longitudinal end on an opposite side of the circular flat from the fastening hook, and a magnet under the circular flat. Placing the interior surfaces of the first buckle portion against the interior surfaces of the second buckle portion causes the magnets to engage each other and the fastening hooks of each buckle portion to enter the fastening openings of the other buckle portion, to lock the two buckle portions together and prevent disengagement under tension in opposing directions parallel to a longitudinal extent of the buckle assembly.

Abstract: An eyelet button and an assembly method thereof, in which the eyelet button is formed of an eyelet button body and a base plate for fastening with the eyelet button body. The eyelet button body is formed from an eyelet tube, a body peripheral portion formed by everything at one end of the eyelet tube in an axial direction, and a plurality of inverted fasteners formed by everting at the other end of the eyelet tube in the axial direction. The base plate is formed of a base plate body, with a mounting hole with an inner wall having a plurality of protruded tooth portions. A gap is formed between two adjacent protruded tooth portions. When the eyelet tube passes through the mounting hole, the inverted fasteners pass through the gaps to rotate with the eyelet tube so as to be connected and fixed to the corresponding protruded tooth portions.

Abstract: A connector assembly is formed from a female portion, a male portion and a locking cover. The female portion has a longitudinal channel with an opening and a slot that extends into the channel. The male portion has a locking post and an indentation that aligns with the slot when the post is inserted into the channel. The locking cover has a locking tooth that extends through the slot and into the channel. The male portion is connected to the female portion by sliding the locking post into the channel until the indentation aligns with the slot, so that the locking tooth rests in the indentation. The male portion is released from the female portion by pulling the locking cover away from the female portion until the locking tooth clears the indentation in the post which is mounted in the channel, and sliding the male portion and female portion away from each other.

Abstract: 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 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.

Abstract: A swivel connector has a female part and a male part that are connected to each other so as to swivel. The female part has a main body with an interior cavity and an open face, and a strap connector. The male part has a plug portion and a strap connector. A ring lock locks the male portion to the female portion and is formed by two side walls connected by two pivot bars, the side walls of the ring lock being rotatably connected to the female part. The male part is locked to the female part by inserting the plug portion into the interior cavity, and rotating the ring lock into a locked position where the open face is blocked by one of the pivot bars. The male part is released from the female part by rotating the ring lock until the open face is not blocked by the pivot bar.
