A reusable protective cover for a male portion of a snap fastener may be configured with a symmetrical convexly-curved continuous upper surface extending from the surface to which the male portion of the snap fastener is attached, to above the male portion of the snap faster, the upper surface having an area that is large in size relative to the size of the male portion of the snap fastener and shaped so that the force of someone stepping on the cover would be spread out over a much larger area than the area presented by the male portion of the snap fastener, thus greatly reducing the pressure on the bare foot of someone stepping on the cover, while also protecting the male portion of the snap fastener. Structure is provided to prevent water entrapment under the cover.

A two-part watch strap (1) including a clasping part (2) and a clasped part (3). The clasping part (2) includes: a clasping-part watch-attaching end; a clasping end opposite the clasping-part watch-attaching end; a strap/band/bracelet portion (4) extending between the watch-attaching and clasping ends of the clasping part (2); and a groove (11) arranged in the strap/band/bracelet portion (4). The clasped part (3) includes: a clasped-part watch-attaching end; a free end (9) opposite the clasped-part watch-attaching end; a strap/band/bracelet portion (6) extending between the watch-attaching and free ends of the clasped part (3); and a protruding portion (10) adjacent to, near, or at the free end (9). The protruding portion (10) is configured to engage with and at least partially lock into the groove (11) of the clasping part (2) so as to secure the free end (9) of the clasped part (3) to the clasping part (2).

Apparatus and method of locking two devices to each other through a receiver base, a pair of pivoting locking tabs, each having first and second arms extending out from a pivot point, and an insert that is partially engaged within a cavity formed by the receiver base and locking tabs. The receiver base is configured to be engageable with a first device. The insert is configured to be engageable with a second device. An optional push button assembly that has a retractable lip is engageable with the receiver base to block rotational movement of the locking tabs unless the lip of the push button is retracted. The apparatus may also include magnetic actuators and corresponding electronic switches that provide two stage locking and, optionally, provide contact state signaling to an external controller and computer to verify locked/unlocked status of the insert relative to the receiver base cavity and locking tabs.

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 fastener, of the type comprising a female part (2) including a spring (11, 11a, 11b) and a male part (4) including a stem (5) for engagement with the spring, wherein a chamber (10, 10a, 10b) is provided for housing the spring and including shoulders (12, 12a, 12b) on a buttoning side, the shoulders having a length (L1) longer than a length (L2) of shoulders (13, 13a, 13b) arranged on the opposite side. Thus, a differentiated effort buttoning and unbuttoning mechanism between the stem (5) and the spring (11) is achieved. With respect to prior snap fasteners, the inventive snap fastener provides the advantage of requiring very small buttoning efforts, much smaller than those necessary for unbuttoning the snap fastener, thereby facilitating the snap fastener closing operation while providing a tightness closure upon having buttoned the snap fastener male and female parts.

A releasable interlocking device comprising a pair of interactive plates, for fastening to apparel utilising a system of two interactive plates which when brought together utilises 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.

This invention relates to a button containing two pieces that snap together to fasten multiple articles of clothing. The top piece is made of two parts: a ridged cover that is used as both a pressure point to secure the invention, and a grip to rotate the invention in and out of the locked position, said ridged cover including a male fastener that attaches the rigged cover to the plate with hinges that functions as the bottom of the top piece of the snap and lock. The hinged place contains a female fastener that secures the two pieces of the top portion. The bottom piece of the snap and lock invention is made up of three parts: a plate to receive the hinges from the top piece, with a cavity to allow the hinges to rotate into a locked position, a curved structure that serves to connect the hinge/cavity plates and the article of clothing attachment, and a rivet that attaches to the article of clothing and the snap and lock invention.

A snap button has a female portion formed from a cap and a socket that are connected together with a piece of fabric in between. The cap is formed from a base body having a circumferential flange with interruptions therein so that the flange can be bent outward during assembly. The socket is formed by a disc having a central aperture and a peripheral rim, as well as an annular insert disposed within the socket. The cap is connected to the socket by pressing the socket onto the cap until the flange bends around the annular insert to anchor the cap to the socket with the fabric trapped between. A male portion having a stud is connected to the female portion by snapping the stud into the socket such that the stud extends entirely through the socket and into the cap.

Provided is a snap button in which a swaged portion of a to-be-swaged pin is not visible from users. The snap button comprises a snap button body and a cap to be connected to the snap button body with a cloth interposed between them. The snap button body includes a base; a pin to be swaged, which protrudes from an inner surface of the base, the inner surface being placed to face the cloth; and an engaging portion provided on an outer surface opposite to the inner surface of the base. The cap comprises a cap body including a cap base; and a metal eyelet attached to an inner surface of the cap base, the inner surface being placed to face the cloth. The eyelet comprises a cylindrical portion for receiving the pin which has pierced the cloth and swaging the pin on the inner surface of the cap base.

Disclosed is a snap fastener, comprising a face fastener (1) and a locating fastener (2) which are snapped with each other, wherein the face fastener (1) comprises a face shell (11) provided with an installation chamber (111), and a locating pin (12) made of plastic and integrally formed; and the locating pin (12) comprises a base (121), a rod body (122) and anti-rotation protrusions (125). In the implementation of the snap fastener of the present invention, the face fastener (1) can be separated into the face shell (11) and the locating pin (12), and the locating pin (12) is manufactured into a standard part for batch production and storage, thereby adapting face shells (11) with continuously updated designs, shortening delivery time, and reducing costs.
