Abstract
IMPROVED PLASTIC DRIVE FASTENER
Abstract of the Disclosure Disclosed is a one piece plastic drive fastener including a head and a shank with the shank having an axis and comprising an elongate body portion having a generally polygonal cross-section and providing a plurality of radially outwardly facing substantially flat surfaces. A first plurality of integral resilient independent wings extend radially outwardly from at least one of the flat surfaces at axially spaced intervals. The junctures of the first plurality of wings along the at least one of the surfaces is each along a respective straight line forming a bend line for flexure of the first wings during introduction of the fastener into a complementarily apertured workpiece. A second plurality of integral resilient independent wings extend from and are positioned in axially spaced relation along at least one of the other of the surfaces and are angularly disposed so as to incline in the direction of the head. Each of the second wings has a thickened section formed at its juncture, whereby each thickened section coacts with its respective second wing to define a bend line along which each second wing flexes which bend line is spaced radially from the respective surface to which each of the second wings is attached.

Description
Background of the Invention Plastic drlve fasteners of various configurations are known in the art and more particularly particular reference should he made to the paten-t to Edwin Grant Swick and John ~rederick Nelson, Vnited States Letters Patent 3,810,279 issued May 14, 197~ and assigned to the common assignee of the present invention. Such fasteners while suitable for many applications have a single inherent problem, namely, the insertion force for installing the fastener in an aperture or bore of a work piece is substantially equal to the force required for removal of the fastener from such an aperture or bore. In some applications it has been found desirable to provide a fastener which can be xeadily installed but which requires an excessive amount of force to remove same.

Detailed Description of the Preferred Emhodiment -- -- .. ... , _ A plastic drive fastener of the improved variety con-templated by the pre~ent invention i9 generally designated by the mlmeral 10 and include~ ~ head (12) ~nd a chank (14). While the present invention shows the head ~2) ~ being 8 domed sealing head, it should be recognized by tho~e ~killed in the art that this :, `
37~7 Case 3fi23 is merely one showing of a head form. Such a fastener, as con-ternplat~d by the present invention, can have a single head (12), as shown, or may include a multiplicity of axially spaced heads of the type norrnally used to fasten trim panels to ~utomotive 5 door interiors, not shown.
The importance of the present invention relates to a plastic drive fastener which can be readily installed into an apertured panel or a bore within a thicls panel in which the re-moval force is far in excess of the force of installation. An em bodiment of such a fastener is shown in Fig. 1 through 4, 7 and 8C. ~he shank (14) of such a fastener i6 generally non-circular or polygonal in cDnfiguration and provides a plurality of axially extending flat surfaces (16~ which in the present embodiment are four is~ nul~l)er, however, it ~houlcl he appreciated that any 15 equal number of flat surfaces will suffice. Extending outwardly from the flat surfaces (16) are a plurality of axially spaced flexible resilient wing elements (l8~ which are provided with a generally tapered undersurface (20) and a radinlly extending upper ~urface (22), as best seen in Fi~. 2.
Along at least one flat 6urfsce (16) ~re ~ plurality of certain resilient wing elements (30) which are angularly dispos-ed relative to the ~xis of the 8hank (14~ and tilt or are inclined upwardly, as viewed in the drawing, toward the head (12).
The initial devel~pment work of this fastener was t~ ~ltili.ze a tilted wing, as seen in Fig. 6, which had substantially the same configuration as the flexible wing elements ~18) that extend radially outwardly. As 37~7 Case 3623 can be seen in Fig. 6 these elements ~enerally designated (32) fle7~ed along a straight line formed by their juncture with the flat ~urface (16). ~he insertion and removal forces of such items were slightly different.
Further development resulted in the present embodi.~nt shown in Fig. 1 through 4 and Fig. 7 wh~rein a thickened section or portion (34) is added to each of the angled wing elem~nts (30) this results in the certain wing elements (30) having a bend line (36), as best seen in Fig. 7, which is generally parallel to sur-face (16) but laterally spaced outwarclly therefrom. In essence, this creates a short stubby wing element (30) that can be readily inserted into an aperture or bore but which resists with great tenacity the removal of the fa~tener from the aperture or bore.
'I ests were conductecl on various configurations of wings and the results of SUCII tests are shown in pourlds of force require(l to push the fastener in and to pull the fastener out. ~rhe figures are displayed in reference to the wing configurations shown in Fig. 8A, 8B and 8C, the latter being the embodiment of the present in~tention.
