A quick release apparatus for rapid disconnection of a waist belt from a self-contained breathing apparatus support frame, including frame connectors disposed on a lumbar support pad. The frame connectors and inserted through horizontal slots on the SBCA support frame and present an aperture for insertion of slide clips that tether the SCBA support frame to the lumbar support pad. The support pad, in turn, may be removably attached to a trucker's belt or integrated therein. In an emergency, the slide clips may be rapidly removed with a simple pull to effect a full and compete release of the SCBA support frame from the waist belt while leaving the waist belt and its accoutrements on the user.

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 fastening system includes two elongated profile parts, one of which includes a guiding surface or ramp for positioning it with respect to the other profile part, for releasably fastening a carrier to a holder. Deformations of a rib of one profile or a clamping hole of the other profile are adapted to position the one profile in substantially clamped state in the other profile in the longitudinal direction.

A male connector having two (or more) tines or prongs extending from a joined surface or head is inserted into a female connector. This is accomplished by way of pushing the two tines into an entry portal of the female connector which, as the tines are pushed into the female connector, guides the tines away from each other and perpendicular to their direction of entry. The tines may have repeated triangular apexes on the surface, similar to a cable tie, while the female connector has oppositely-disposed triangular surfaces such that when the tines are pushed into the female member, they are irreversibly or substantially irreversibly held into the female connector.

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.

A hair accessory device includes a male snap member and a female snap member. The female snap member mates with the male snap member. At least one of the snap members includes an aperture for feeding hair there through. The male and female snap members are moveable between a first position, in which a snap is formed and the hair is retained, and a second position, in which the snap is disengaged. A hair accessory is placed in communication with the male snap member, the female snap member, or both male and female snap members. Preferred implementations employ pluralities of male and female snap member, and dual snap members.

A system can include a first portion of a fabric fastener, a second portion of the fabric fastener, wherein the first portion and the second portion are configured to mechanically connect with each other and to resist separation from each other once connected, and wherein the first and second portions include a plurality of corresponding electrical contacts configured to form a plurality of individual electrical connections when the first portion is mechanically connected with the second portion.

A fastening device has a first fastening member with a plurality of teeth and a second fastening member with a plurality of sockets which are sequentially engagable in tooth and socket pairs in an engagement direction by relative rotation of the tooth and socket. Each tooth has a first surface and a second surface fixed relative to the first surface. Each socket has a recess defined by a first wall and second wall fixed relative to the first wall. Upon engagement, the first and second surfaces of the tooth abut the respective first and second walls of the recess and prevent relative movement of the tooth in the engagement direction and a portion of the first wall of the socket closely abutting the first surface of the tooth is disposed between the tooth and a portion of the first fastening member and prevents relative separation of the tooth and socket.

Selectively attachable ornaments are shown and described. The ornaments comprise a male and a female component which are attachable to one another from opposite sides of an opening through an article, such as a shoe, clothing, pursue, handbag, backpack, etc. In one example, the male component includes s a shaft with a beveled engagement portion, and the female component includes two spaced apart semi-cylindrical legs with a radially inward flange or lip that defines an opening into which the male component engagement portion is inserted during an attachment operation. The beveled engagement portion has at least one location where its diameter exceeds that of the opening between the radial inward flange/lip of each semi-cylindrical leg. In another example, the female component is a cylinder with one or more circumferential cut-out sections along a port of its length and an annular opening for receiving the male component's engagement portion. The male component has a beveled engagement portion with at least one section having a diameter greater than that of the annular opening. When the male component is snap-fittingly engaged to the female component, an audible pop sound is emitted by the elastic deformation and relaxation of the engagement portion.

A size adjusting structure has two members forming a secured structure when the two members are engaged with each other. One of the two members can contain an engaging protrusion and the other member can contain an engaging recess on one side and a substantially flat and hole-less surface on the opposite side. The size adjusting structure can be part of a cap, hat, bag, or any other consumer products.
