Abstract
A strap fastener comprising a pair of engageable magnetic fasteners of opposite polarity to each other engageable or a common axis, a strap engagement portion connected to each magnetic fastener and extending transverse to said common axis of engagement of said magnetic fasteners; and at least one protrusion to reside against a perimeter of an opposed magnetic fastener to resist movement of one magnetic fastener with respect to the other transverse to said common axis on which they engage.
Claims24
A fastener including a housing and a magnetic member, said magnetic member including a first magnetic surface and an opposing second magnetic surface corresponding to a first magnetic pole and a second magnetic pole respectively, said first and second magnetic poles defining a magnetic axis therebetween, said housing including:
- a receptacle for receiving said magnetic member;
- a strap receiving means extending from said receptacle;
- and
- a stopping mechanism provided in said housing adapted to engage a matching fastener containing a matching housing, said stopping mechanism preventing lateral slippage between said fastener and said matching fastener in a direction substantially perpendicular to said magnetic axis when said fastener and said matching fastener are being coupled, said stopping mechanism further facilitating disengagement of said fastener from said matching fastener by providing a pivotal support to said fastener so that the engaged first magnetic surface of said fastener can be pivotally moved away from said matching fastener unobstructed by the housing of said matching fastener by applying force on said strap receiving means about said pivotal support.
The fasteners of claim 28, wherein said matching side wall of said matching fastener protrudes above said matching second magnetic surface of said matching magnetic member.
A fastener comprising a pair of engageable magnetic fasteners of opposite polarity to each other engageable on a common axis and a strap engagement portion connected to each magnetic fastener and extending transverse to said common axis of engagement of said magnetic fasteners, said fastener including at least one protrusion to reside against a perimeter of an opposed magnetic fastener to resist movement of one magnetic fastener with respect to the other transverse to said common axis on which they engage, wherein said protrusion facilitates disengagement of said magnetic fasteners by providing a pivotal support for the separation of said magnetic fasteners of opposite polarity.
