Abstract
Snap fasteners are attached to a fabric or substrate and resist water migration from one side of the fabric or substrate to an opposite side of the fabric or substrate. The water migration resistant snap fasteners resist water migration through the fabric to which the snap fastener is attached while maintaining secure attachment to the fabric. The water migration resistant snap fasteners have radially offset patterned circles of gripping protrusions which do not penetrate through the fabric. Also, the radial patterned circles of gripping protrusions securely grip the fabric and maintain the snap fasteners in the proper location on the fabric.
Claims20
A water migration resistant device attachable to a fabric and releasably engagable with a mating snap fastener member, the water migration resistant device comprising:
- a first member having an engagement portion on a first side and being releasably engagable with the mating snap fastener member, the first member having a fabric contact side opposite the first side;
- a plurality of first fabric gripping protrusions on the fabric contact side of the first member, the first fabric gripping protrusions being non-fabric-penetrating protrusions;
- a second member lockingly engagable to the first member and having a fabric contact side;
- and
- a plurality of second fabric gripping protrusions on the fabric contact side of the second member, the second fabric gripping protrusions being non-fabric-penetrating protrusions;
- wherein the plurality of first and second fabric gripping protrusions are offset from each other such that during use of the water migration resistant device the first and second members are lockingly engaged with each other with the fabric captured between the first and second members without the first and second fabric gripping protrusions penetrating the fabric.
A water migration resistant device attachable to a fabric and releasably engagable with a mating snap fastener member, the water migration resistant device comprising:
- a water migration resistant snap fastener member having:
- a body portion having an engagement portion on a first side of the body portion releasably engagable with the mating snap fastener member and a fabric contact side opposite the first side;
- a plurality of first fabric gripping protrusions on the fabric contact side of the body portion of the snap fastener member, the first fabric gripping protrusions being non-fabric-penetrating protrusions;
- and
- a water migration resistant snaptop lockingly engagable to the water migration resistant snap fastener member and having:
- a body portion having a fabric contact side;
- a plurality of second fabric gripping protrusions on the fabric contact side of the body portion of the snaptop, the second fabric gripping protrusions being non-fabric-penetrating protrusions;
- wherein the plurality of first and second fabric gripping protrusions are offset from each other such that during use of the water migration resistant device the water migration resistant snap fastener member and the water migration resistant snaptop are lockingly engaged with each other with the fabric captured between the water migration resistant snap fastener member and the water migration resistant snaptop without the first and second fabric gripping protrusions penetrating the fabric.
A water migration resistant snap fastener attachable to a fabric, comprising:
- a stud having a socket engagement portion on a first side and a fabric contact side opposite the first side;
- a plurality of first fabric gripping protrusions on the fabric contact side of the stud and arranged in a generally circular pattern, the first fabric gripping protrusions being non-fabric-penetrating protrusions;
- a first snaptop lockingly engagable to the stud with the fabric therebetween during use, the first snaptop having a fabric contact side;
- a plurality of second fabric gripping protrusions on the fabric contact side of the first snaptop and arranged in a generally circular pattern, the second fabric gripping protrusions being radially offset from the first fabric gripping protrusions and being non-fabric-penetrating protrusions;
- a socket having a stud engagement portion on a first side and a fabric contact side opposite the first side, the stud and the socket being releasably engagable with each other;
- a plurality of third fabric gripping protrusions on the fabric contact side of the socket and arranged in a generally circular pattern, the third fabric gripping protrusions being non-fabric-penetrating protrusions;
- a second snaptop lockingly engagable to the socket with the fabric therebetween during use, the second snaptop having a fabric contact side;
- and
- a plurality of fourth fabric gripping protrusions on the fabric contact side of the second snaptop and arranged in a generally circular pattern, the fourth fabric gripping protrusions being radially offset from the third fabric gripping protrusions and being non-fabric-penetrating protrusions.
