  • FASTENER DEVICE AND METHOD FOR ATTACHING POLYESTER FIBER PANELS TO A SUBSTRATE
    Publication number: 20220268303
    Abstract: A method and fastening device for attaching polyester fiber panels to a substrate, such as a wall or a ceiling. The fastening device comprises an anchor part for attachment to the substrate and a fastening part for attachment to the panel. The fastening part comprises a cylindrical portion, a helical member surrounding the cylindrical portion for penetrating the panel upon rotation of the helical member and a recess in the cylindrical portion for receiving the anchor part. The thread angle of the leading edge of the helical member is greater than the thread angle of the trailing edge.

  • Fastener device and method for attaching a panel of semi-rigid material to a substrate
    Patent number: 6652208
    Abstract: A fastener device for attaching a rear face of an acoustic panel to a substrate, comprising an anchor part for attachment to the substrate and a screw part having an inner end rotatably held by the anchor part. The screw part has a helical member with an outer end capable of penetrating the rear face of the panel when rotated by an elongated drive rod projecting from the outer end. The drive rod can penetrate a panel and is accessible from the front face of the panel to cause the helical member to penetrate and engage a rear portion of the panel, and to secure the panel onto the substrate. The drive rod is removable from the outer end of the screw part after the panel has been secured so that the fastener is essentially concealed within the panel.
