Panel fastener assembly

A panel fastener assembly, comprising:

• a panel retainer comprising a panel holder and a first connector disposed at opposing longitudinal ends of the panel retainer;
• and
• a sheet retainer comprising a sheet anchor and a second connector disposed at opposing longitudinal ends of the sheet retainer;
• wherein one of the first and second connectors comprises a neck longitudinally extending to a head, the head presenting a substantially flat face opposite the neck and a contact surface disposed between the neck and an outer edge of the head, the outer edge defining an outermost perimeter of the head, the contact surface extending along a straight path from the neck to the outer edge, and the head including an insertion surface disposed between the outer edge and the flat face, the insertion surface extending from the outer edge at a chamfer angle such that the head has a generally frustoconical shape from the outer edge to the face;
• wherein the other of the first and second connectors comprises a body having an outwardly facing longitudinal mating side presenting a mating surface, and a plurality of resiliently deflectable locking elements extending from the mating side of the body at edges of the mating surface radially disposed about a central axis, each locking element of the plurality of locking elements being configured to be resiliently deflectable away from the central axis, and each locking element defining a flat locking surface opposing the mating surface;
• wherein the contact surface defines a tangent line that radially intersects the central axis at a contact angle, the contact surface extending radially outwardly from the neck such that the contact angle is obtuse;
• wherein each locking element comprises a support wall perpendicular to the mating side of the body and a flange projecting radially inward from the support wall to present the locking surface over and longitudinally opposing the mating surface, the flange being perpendicular to the support wall such that the locking surface is parallel to the mating surface, and the support wall being resiliently deflectable away from the central axis;
• and
• wherein the panel retainer and the sheet retainer are connectable via the first and second connectors, such that when the face of the head is disposed adjacent the mating surface of the body the locking surface of each locking element is disposed about the contact surface of the head to prevent awayward movement between the head and the body, thereby connecting together the panel retainer and the sheet retainer.
