Abstract: A rivet system comprises (i) a screw comprising a threaded shaft, (ii) a rigid sleeve comprising a hole extending therethrough for receiving the threaded shaft, (iii) a deformable sleeve comprising a hole extending therethrough; and (iv) a rigid base comprising a threaded hole on a first end of the rigid base, where the first end is configured to insert and advance into the hole of the deformable sleeve to allow the threaded hole of the rigid base to threadedly engage with the threaded shaft of the screw, and where the rigid base comprises an annular channel configured to receive at least part of the deformable sleeve when the first end of the rigid base is inserted and advanced into the hole of the deformable sleeve.

Abstract: A raised toilet seat includes a seat body that defines an oval opening. The seat body has a front portion and a back portion that encompass, respectively, opposing ends of a major axis of the oval opening. The seat body also has first and second side portions that encompass, respectively, opposing ends of a minor axis of the oval opening. The raised toilet seat further includes a fastening assembly integrated into the first side portion of the seat body. The fastening assembly includes a rotatable knob and a threaded member affixed to the rotatable knob. The threaded member extends inward from the rotatable knob toward the oval opening. The fastening assembly also includes a clamp in threaded communication with the threaded member. The clamp extends below an underside of the seat body, and rotating the rotatable knob adjusts a positioning of the clamp along the threaded member.
