Filed:

Apr 4, 2000

Appl. No.:

9/542604

Inventors:

Leonid Roytberg - Brookline MA
Howard N. Wieland - Holliston MA

Assignee:

American Engineered Components, Inc. - Brighton MA

International Classification:

F16B 1306
F16B 3704

US Classification:

411 61

Abstract:

A one-piece insert fastener adapted for securement within an aperture in a panel by a threaded member. The insert fastener includes a base having a top surface, a bottom surface and a pair of outwardly protruding wings. In one embodiment, the base additionally includes a single-threaded, helical edge which is shaped to define an opening. In another embodiment, the base additionally includes an internally threaded drawn barrel which is shaped to define an opening. The insert fastener also includes a pair of resilient, spaced apart legs which are formed on and protrude out from the base. Each of the pair of legs includes an outwardly angled upper section, an inwardly angled middle section and a lower section. In use, the insert fastener is disposed into the aperture in the panel until the pair of wings abuts against the outer surface of the panel. The threaded member is rotatably driven into the opening in the base, the threaded member engaging the base upon rotation.

Abstract:

A one-piece insert fastener adapted for securement within an aperture in a panel by a threaded member. The insert fastener includes a base having a top surface, a bottom surface, a pair of outwardly protruding wings and a single-threaded, helical edge which is shaped to define a opening. The insert fastener also includes a pair of resilient, spaced apart legs which are formed on and protrude out from the base. Each of the pair of legs includes an outwardly angled upper section, an inwardly angled middle section and a lower section. In use, the insert fastener is disposed into the aperture in the panel until the pair of wings abuts against the outer surface of the panel. The threaded member is rotatably driven into the opening in the base and is engaged by the helical edge. Continued rotational driving of the threaded member causes the threaded member to contact and outwardly urge the pair of spaced apart legs into contacting engagement with the inner surface of the panel, thereby securing the insert fastener onto the panel. Insertion of the above fastener into a panel requires less than ten pounds of force.
