Multi-aperture plate fastening

A plate-fastener assembly comprising:

• (a) a first plate defining a first aperture array and a second aperture array;
• the first arced aperture array comprising a plurality of first minor apertures and a plurality of first major apertures;
• the second arced aperture array comprising a plurality of second minor apertures and a plurality of second major apertures;
• (b) a second plate defining a first fastener hole and a second fastener hole;
• (c) a first fastener and a second fastener, each of the fasteners comprising a tab, a plurality of transverse plates defining an annular slot, a transverse catch, and two inserts extending normal to the transverse catch;
• the first fastener being disposed in the first fastener hole such that the second plate occupies the first fastener annular slot and thereby retains the first fastener, the second fastener being disposed in the second fastener hole such that the second plate occupies the second fastener annular slot and thereby retains the second fastener;
• the first and second fasteners binding the first plate and the second plate together.

A plate-fastener assembly comprising:

• (a) an arced plate comprising an inner surface and an outer surface, the arced plate defining a first arced aperture array, a second arced aperture array, a first fastener hole, and a second fastener hole;
• the first arced aperture array comprising a plurality of first minor apertures and a plurality of first major apertures;
• the second arced aperture array comprising a plurality of second minor apertures and a plurality of second major apertures;
• (b) a first fastener and a second fastener, each of the fasteners comprising a tab, a plurality of transverse plates defining an annular slot, a transverse catch, and two inserts extending normal to the transverse catch;
• the first fastener being disposed in the first fastener hole such that the arced plate occupies the first fastener annular slot and thereby retains the first fastener, the second fastener being disposed in the second fastener hole such that the arced plate occupies the second fastener annular slot and thereby retains the second fastener;
• wherein the first fastener and the first arced aperture array are formed such that the two first fastener inserts can simultaneously occupy any two consecutive first minor apertures;
• the second fastener and the second arced aperture array being formed such that the two second fastener inserts cannot simultaneously occupy any two consecutive second minor apertures.
• each first minor aperture having the same first shape and each second minor aperture having the same second shape.
• the second arced aperture array comprising more minor apertures than the first arced aperture array, the first and second shapes being equal
• each of the fasteners comprising a neck, a portion of each neck being coplanar with the arced plate;
• each plurality of transverse plates comprising two wings and a circular shield, the first fastener wings being separated from the first fastener shield by the first fastener neck, the second fastener wings being separated from the second fastener shield by the second fastener neck;
• the arced plate being wrapped into a truncated cone.
