ASSEMBLY FOR FASTENING A LAYER OF COMPRESSIBLE MATERIAL TO A RIGID MEMBER |
摘要 |
<p>An assembly for fastening a compressible layer of insulation includes a threaded screw projecting through the center of a flat circular disk of a resilient plastic material. A central hub on the disk is received between the head and a flange spaced below the head to hold the disk adjacent the head, the hub being defined in part by resilient fingers which flex outwardly to let the flange pass through the hub as the screw and the disk are assembled together. An annular surface is formed on the underside of the disk at the periphery thereof to engage the insulation and ribs which decrease in width are formed on the underside of the disk and project radially from the hub to the peripheral surface so that an uplift force causes the disk to flex upwardly progressively from the periphery toward the center.</p> |
