Abstract
A stud snap system includes a pin, a receiver, and a stud. The receiver fixedly engages with the pin and also fixedly engages with the stud to attach of the stud snap system to a material. The material can include apparel, clothing, sportswear, outdoor gear, fabrics, coverings, and textiles. Use of the receiver affords a large selection of options for materials and geometries to be used for the stud since the pin is not directly engaged with the stud.
Claims7
A system comprising:
- a pin including a shaft portion and a head portion, the shaft portion including a first end portion, a second end portion, and a longitudinal length, the head portion being adjacent the first end portion of the shaft portion, the second end portion of the shaft portion including a tip portion that is substantially pointed to pierce a material when the pin is in an unaltered state and that is substantially blunt when the pin is in an altered state;
- a receiver including a pin enclosure portion and a backing portion, the pin enclosure portion having first and second end portions, the first end portion having an opening and the second end portion being enclosed by a top portion, the opening so sized to receive the shaft portion of the pin, the pin enclosure portion having a longitudinal axis, the top portion of the receiver having a hardness so selected to change the pin from the unaltered state to the altered state when the tip portion of the pin is forced against the top portion, the top portion having a protrusion portion, the top portion so shaped that the protrusion portion moves from an un-extended position to an extended position in one or more directions away from the longitudinal axis of the pin enclosure portion when the pin is forced against the top portion and changed from the unaltered state to the altered state;
- and
- a stud including a stud top portion and a backing enclosure portion, the stud top portion having an opening so sized to receive the pin enclosure portion when its protrusion portion is in the un-extended position, the stud top portion having an internal surface so sized to fixedly engage with the pin enclosure portion when the protrusion portion is in the extended position, the backing enclosure portion so sized and positioned with respect to the stud top portion to receive the backing portion of the receiver when the stud top portion has received at least a portion of the pin enclosure portion of the receiver.
