A quick-release fastener for attaching helmet components such as facemasks and visors to a protective helmet. The quick release fastener or mechanism includes a securing mechanism having magnetic components to facilitate quick removal of the helmet component with minimal movement to the player's head and neck via magnetic biasing.

To provide a fastening tool that can solve problems that are raised upon locking the opening portion of clothing, baggage or the like, and can also positively lock the portion to be locked at a desired position without the necessity of any processing jobs, such as caulking, sewing and the like, so as to be freely detachably locked. The fastening tool is provided with at least a pair of fastening members a and b which have detachably attaching portions that are freely detachably attached to each other, and each of the fastening members a and b has a substrate with a piercing needle formed on one of the surfaces, a bottom plate that is penetrated by the piercing needle, a pierce catch made of a cap-shaped member to cover the tip of the penetrated piercing needle, and detachably attaching portions that are freely detachably engaged with each other.

An accessory attachment system that embodies devices and a method for converting clasp-style fasteners to push-pull detachable fasteners, thereby facilitating attachment of accessories having clasp-style fasteners or any accessory having opposing ends so that they are “ready-to-wear”.

A prosthetic attachment for a prosthetic limb. A base is attached to the prosthetic limb. The base has a magnet that is surrounded by base valleys and base peaks. An attachment piece is attached to the prosthetic attachment. The attachment piece also has a magnet that is surrounded by attachment piece valleys and attachment piece peaks. The magnetic force between the base magnet and the attachment piece magnet attracts the prosthetic attachment to the prosthetic limb so that the base peaks and valleys mates with the attachment piece peaks and valleys for a secure removable attachment. In a preferred embodiment a locking device is used to further secure the prosthetic attachment to the prosthetic limb. In a preferred embodiment the prosthetic attachment is a prosthetic hand and the prosthetic limb is a prosthetic arm.

A magnetic buckle including a buckle base assembly and a locking assembly is disclosed. A first magnet and an adjustable lock hole are disposed on buckle base assembly, a lock tongue and a second magnet are disposed on locking assembly, two moving portions are disposed at the buckle base assembly respectively, and two unlocking portions are disposed within the buckle base assembly. When the lock hole is close to the lock tongue, the first magnet attracts the second magnet to guide the lock tongue into the lock hole to achieve locking. When the moving portions are pressed toward each other, the unlocking portions move toward the lock tongue to separate the parts of the lock tongue combined with the buckle base assembly for reducing an attractive force between the first magnet and the second magnet, so as to facilitate separation between the buckle base assembly and the locking assembly.

A hook formed into a body formed into a hook shape and having a neck and fabricated from nonferromagnetic material with the body having a first end and a second end. The neck is proximate the first end. One side of the neck includes a center ridge with a flat top surface with either a magnet or ferromagnetic material embedded in the center ridge. The hook also includes a closure having a first closure end and a second closure end and a channel with a floor flanked by two lateral sides. A second magnet or a ferromagnetic material is embedded into the floor opposed to the first magnet or ferromagnetic material. The closure being pivotally and/or pivotally and slidably attached to the hook body by at least one pin. The magnet(s) and/or ferromagnetic material hold the closure in a closed position enclosing a defined space.

Magnetic textile fasteners are disclosed. In one embodiment, the textile fastener may include a spherical member and two receiving members. Each of the receiving members may include a surface portion and an opening within the flat surface portion, wherein the opening is configured to receive the spherical member. In an embodiment, textiles are placed between each receiving portion and the spherical member while the spherical member is inserted at least partially into the openings. The spherical member thereby applies a force between each textile and its respective receiving member. Magnetic interaction between the spherical member and the receiving members may maintain the force between the textile and the receiving members.

A connector assembly comprising a base having an adapter and a retainer, the adapter configured to reversibly couple to a wearable device using a magnet, ferromagnetic material, or combinations thereof; an elastic member partially positioned within the retainer, the elastic member having a first loop portion adjacent a first end of the retainer and a second loop portion adjacent a second end of the retainer; and wherein the elastic member is configured to stretchably move with respect to the base such that, responsive to a force pulling the first loop portion over a portion of an eyewear frame, the second loop portion changes in size.

Stop member includes: a first member including a first insert to be inserted into a slider via a rear mouth of the slider, and a first base positioned rearward of the first insert; and a second member including a second insert to be inserted into the slider via a slit extending between the rear mouth and a front mouth of the slider, and a second base to be overlaid onto the first base. The first and second bases are configured to effect magnetic attraction and/or repulsion between the first and second bases when the first and second bases are overlaid. The second base rotates relative to the first base in accordance with the magnetic attraction and/or repulsion to allow the second insert to pivot toward the slit.

A magnetic buckle including a buckle base assembly and a locking assembly is disclosed. A first magnet and an adjustable lock hole are disposed on buckle base assembly, a lock tongue and a second magnet are disposed on locking assembly, two moving portions are disposed at the buckle base assembly respectively, and two unlocking portions are disposed within the buckle base assembly. When the lock hole is close to the lock tongue, the first magnet attracts the second magnet to guide the lock tongue into the lock hole to achieve locking. When the moving portions are pressed toward each other, the unlocking portions move toward the lock tongue to separate the parts of the lock tongue combined with the buckle base assembly for reducing an attractive force between the first magnet and the second magnet, so as to facilitate separation between the buckle base assembly and the locking assembly.
