DETAILED DESCRIPTION OF THE INVENTION

FIG. 2 illustrates an isometric view of a fastening clip 20 positioned through a hole 22 formed in a panel 24 according to an embodiment of the present invention. FIG. 3 illustrates a top plan view of the fastening clip 20 positioned through the hole 22 formed in the panel 24. FIG. 4 illustrates a cross-sectional view of the fastening clip 20 positioned through the hole formed in the panel 24 through line 4-4 of FIG. 3. Referring to FIGS. 2-4, the fastening clip 20 may be formed of metal, plastic, or various other suitable materials. The fastening clip 20 may be, for example, an integrally formed piece of fabricated metal configured to secure panels, such as trim and body panels of a vehicle, together.

Referring to FIG. 4, in particular, the fastening clip 20 includes a base 26 integrally connected to a reduced panel securing portion 28 defining a notch 30. The outer circumference or perimeter of the reduced panel securing portion 28 is less than that of the base 26. The reduced panel securing portion 28 is, in turn, integrally connected to upright resilient arms or beams 32. Two opposed beams 32 are spaced apart by a gap 34. Thus, the beams 32 may flex toward one another if sufficient force is applied. The outer surfaces of each beam 32 include a plurality of vertically oriented tangs 36. The tangs 36 are ramped, or toothed members. Each tang 36 includes a downwardly sloped ramp 38 that abruptly connects to a lower edge 40. Distal tips 42 of the beams 32 are chamfered toward one another. While two beams 32 are shown, the fastening clip 20 may include more beams 32 than those shown. Additional beams 32 may provide additional fastening strength and a more robust fastening clip 20.

Each beam 32 also includes wings or flaps 44 along a substantial height of the beam 32 on either side thereof. Flaps 44 flank each beam 32. The flaps 44 angle inwardly toward the center of the fastening clip 20. The flaps 44 provide bracing support, thereby adding stability to the beams 32 and the fastening clip 20. The flaps 44 are configured to cooperate with mating holes formed in panels. The flaps 44 assist in properly locating the beams 32 with respect to mating holes in that, upon insertion, act to direct the beams 32 toward the center of the mating holes.

While not shown, the fastening clip 20 may also include a foam insert, if desired. The foam insert may provide, for example, a seal or sound proofing.

In order to secure the fastening clip 20 to the panel 24, the fastening clip 20 is pushed into the hole 24 in the direction of arrow A. Optionally, the panel 24 may be urged toward the fastening clip 20 in the direction of arrow B. During this movement, the distal tips 42 move into the hole 22. The inwardly chamfered distal tips 42 allow the fastening clip 20 to easily pass into the hole 22. Because the distal tips 42 are inwardly chamfered, the distal tips 42 do not snag the area of the panel 24 that defines the hole 22. Rather, the inwardly chamfered distal tips 42 allow the fastening clip 20 to effectively self locate the fastening clip 20 into the hole 24. For example, if the fastening clip 20 is out of alignment with the hole 22, the inwardly chamfered distal tips 42 allow the fastening clip 20 to slide toward and into the hole 22.

As the fastening clip 20 continues to move into the hole 22, the area of the panel 24 that defines that hole 22 squeezes the distal tips 42 toward one another. Consequently, the beams 32 flex toward one another, and the fastening clip 20 moves into the hole 22. With continued movement of the fastening clip 20 in the direction of arrow A, the ramped portions 38 of the tangs 36 slide over the edges of the panel 24 that define the hole 22. In effect, the tangs 36 provide a ratchet-like mating surface. While the panel 24 may slide over the ramped portions 38 in the direction of arrow A, the straight lower edges prevent the panel 24 from retreating over the beams 32 in the direction of arrow B.

The fastening clip 20 continues to be moved in the direction of arrow A, until the reduced panel securing portion 28 encounters the edges of the panel 24 that define the hole 22. The edges of the panel 24 snap into the reduced panel securing portion 28. Thus, the reduced panel securing portion 28 snapably secures to the panel 24. The wide base 26 prevents the fastening clip 20 from further movement in the direction of arrow A. As the reduced panel securing portion 28 snapably secures to the panel 24, the beams 32 flex outwardly to their at rest position.

Referring to FIGS. 2-4, once the fastening clip 20 is secured to the panel 24, a second panel (not shown) may be securely connected to the panel 24 by way of the fastening clip 20. The second panel is urged onto the fastening clip 20 in the direction of arrow B. Optionally, the fastening clip 20 and the first panel 24 may be urged toward the second panel in the direction of arrow A.

Portions of the second panel that define a mating hole (not shown) may slide over the inwardly chamfered distal tips 42. As the second panel moves over the fastening clip 20, the tangs 36 securely engage the portion of the second panel that defines the hole. In particular, the lower edges 40 of the tangs 36 dig into the portion of the second panel that defines the hole. Because the lower edges 40 dig into the second panel, the second panel may be securely set at various heights or depths of the fastening clip 20. Each tang 36 includes lower edges 40 that securely dig into the second panel. Thus, the second panel may be securely fastened by the uppermost tangs 36. Further, the additional panel may continue to be moved relative to the fastening clip 20 in the direction of arrow B, such that other or additional tangs may securely engage the second panel. As such, a plurality of tangs 36 on both beams 32 may provide increased securing strength.

Thus, embodiments of the present invention provide a unitary fastening clip. The unitary fastening clip may securely fasten two panels together through a one-piece design, as compared to the multiple component design of the conventional fastening clip 10, shown in FIG. 1. The one-piece design eliminates the need for manufacturing and assembling additional components. Further, because the tangs 36 are disposed over a substantial height of the beams 32, the fastening clip 20 may securely engage a panel at various distances over the beams 32. Thus, in contrast to the fastening clip 10 shown and described with respect to FIG. 1, a manufacturer or installer does not need to ensure that the fastening clip 20 is positioned at a certain depth or height with respect to a panel.

Overall, embodiments of the present invention provide a fastening clip that securely and efficiently secures panels, sheets, or other such members together.

While various spatial terms, such as front, rear, upper, bottom, lower, mid, lateral, horizontal, vertical, and the like may used to describe embodiments of the present invention, it is understood that such terms are merely used with respect to the orientations shown in the drawings. The orientations may be inverted, rotated, or otherwise changed, such that a front portion is a rear portion, and vice versa, horizontal becomes vertical, and the like.

Variations and modifications of the foregoing are within the scope of the present invention. It is understood that the invention disclosed and defined herein extends to all alternative combinations of two or more of the individual features mentioned or evident from the text and/or drawings. All of these different combinations constitute various alternative aspects of the present invention. The embodiments described herein explain the best modes known for practicing the invention and will enable others skilled in the art to utilize the invention. The claims are to be construed to include alternative embodiments to the extent permitted by the prior art.
