A system for carrying or using a device includes the device and at least one attachment apparatus. The device may include at least one attachment element. The attachment apparatus may include a length of material and at least one attachment point arranged on an end of the length of material. The at least one attachment point may include at least one magnetic feature configured to attach and detach the device and the length of material. The material can include but is not limited to cloth, metallic (magnetic and non-magnetic), fibrous material, and so forth.

Provided is a button attachment tool that can eliminate or reduce rotation of a cap relative to an attachment tool body. A button attachment tool comprises a metal attachment tool body and a synthetic resin cap to which the attachment tool body is coupled. The attachment tool body includes a cylindrical part and a flange part extending radially outward from one axial end of the cylindrical part. The flange part includes a plurality of notches recessed radially inward from a peripheral edge of the flange part. The cap includes a clamping part that is fastened to a radially outer portion of the flange part including the plurality of notches.

A fastener assembly for securing a string and/or netting includes a cord fastener and a cord. The cord fastener includes a clasp defining a first opening and a second opening spaced apart from the clasp. The cord is detachably coupled to the cord fastener, and includes a first end extending through the second opening, and a second end insertable into the clasp. The clasp is configured to allow the cord to be pulled through the clasp in a first direction, and to substantially prevent the cord from being pulled in a second direction that is opposite to the first direction. In some embodiments, the clasp includes a plurality of fingers that extend at an angle relative to a central axis of the second opening.

A fastener assembly for securing a string and/or netting includes a cord fastener and a cord. A cord fastener includes: a body including a base wall; a clasp disposed on the base wall; and an opening disposed on the base wall and spaced apart from the clasp. The base wall has a curved surface between the clasp and the opening. A cord is detachably coupled to the cord fastener and extends through at least one of the clasp or the opening.

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.

Systems and methods are disclosed for fasteners bonded to substrate materials without puncturing the materials. An example fastening system includes a male fastener component and a female fastener. The example male fastener component includes a base plate bonded to a first substrate material without puncturing the first substrate material, and a post integrally formed with the base plate, the base plate and the post formed of a polyurethane material. The example female fastener component includes a housing defining a cavity configured to engage with the post of the male fastener component. The housing is made of the polyurethane material and bonded to a second substrate material without puncturing the second substrate material.

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.
