What is claimed is:
1. A magnetic snap fastener for releasably connecting a first surface and a second surface comprising:
- (a) a female section, having
- a first base washer defining a first hole substantially in the center of the first base washer;
- a magnetic ring defining a second hole substantially in the center of the magnetic ring;
- a non-magnetic cover defining a third hole substantially in the center of the cover and having a continuous peripheral flange, the cover being mounted to the first base washer by the continuous peripheral flange whereby the magnetic ring is held captively between the first base washer and the cover by the first base washer and the cover and whereby the first, second, and third holes are substantially axially aligned;
- a first tubular stem with a fourth hole therethrough and substantially in the center thereof, the first tubular stem extending through the first and second holes, whereby the first, second, third, and fourth holes are substantially axially aligned; and
- first attachment means affixed to the first base washer by the first tubular stem and adapted for attachment to the first surface;
- (b) a male section, having
- a second base washer defining a fifth hole substantially in the center of the second base washer;
- a second tubular stem with a sixth hole therethrough and substantially in the center thereof, the second tubular stem extending through the fifth hole, whereby the fifth and sixth holes are substantially axially aligned; and
- second attachment means affixed to the second base washer by the second tubular stem and adapted for attachment to the second surface;
- (c) whereby insertion of the second tubular stem into at least the second and third holes creates a magnetic force which releasably connects the female and male sections and hence the first and second surfaces attached to the first and second attachment means;
- (d) wherein the first attachment means comprises a first pair of legs and the second attachment means comprises a second pair of legs;
- (e) wherein the first pair of legs is mounted to the first base washer by the first tubular stem and the second pair of legs is mounted to the second base washer by the second tubular stem; and
- (f) wherein the first pair of legs is rotatable with respect to the first base washer and second pair of legs is rotatable with respect to the second base washer.
