Embodiments of the present disclosure generally relate to fastening clip assemblies.
Various assemblies include panels or objects connected to one another. Automobile assemblies, for example, include various panels and structures connected to other panels or structures, or to the automobile frame itself. In particular, snap-fit assemblies may be used to connect the pieces together. Additionally, a fastener may be preassembled with one of the components or panels, while the second component or panel is connected to the preassembly during final assembly. A plurality of the fasteners may be used when connecting relatively large components together. Such fasteners have been provided in a variety of shapes and configurations suitable for the particular components to be connected.
One type of fastener used to connect components together is a symmetrical connector having an insertion portion with a W-shape. W-shape fasteners provide quick and easy assembly. Additionally, the W-shape fasteners securely retain moldings of structural panels, while also being relatively easy to remove.
Another type of known fastener includes opposed securing members that axially collapse as the fastener is inserted into an opening of a panel. The axial collapsing of the opposed securing members allows the opposed securing members to pass through the opening.
Known fastener assemblies are also described in U.S. Pat. No. 6,796,006, entitled “Rib Clip,” U.S. Pat. No. 6,974,292, entitled “One-Piece Reusable Plastic Fastener,” and U.S. Pat. No. 8,613,128, entitled “Push-In Fastener Assembly.”
One known fastener assembly provides a two-piece design and is configured for rectangular openings. Another known fastener assembly provides a one-piece design, but with only two points of retention.
Many known fastener assemblies include multiple pieces. Further, many known fasteners assemblies provide insufficient retention strength. Also, many known fastener assemblies are configured only for square or rectangular openings.
Certain embodiments of the present disclosure provide a fastening clip assembly configured to secure to a component. The fastening clip assembly may include four retaining legs that are configured to directly contact portions of the component to provide four points of contact with the component. A central pedestal may include a central beam and two angled retaining beams extending from the central beam. The two angled retaining beams are configured to exert a triangular retaining force into the component. The two angled retaining beams may form two legs of an isosceles triangle. The four retaining legs and the central pedestal may be integrally molded and formed together. The four retaining legs and the central pedestal may be configured to securely connect the fastening clip assembly to a round opening of the component.
The fastening clip assembly may also include a beveled lead-in nose connected to the central pedestal. The beveled lead-in nose is configured to guide the fastening clip assembly into a round opening of the component.
Each of the four retaining legs may include a flexible root connected to an outwardly-extending angled extension beam, which, in turn, connects to an inwardly-canted ramp. The inwardly-canted ramp is configured to compressively abut into an internal edge of a round opening of the component. The four retaining legs may be regularly spaced about a central longitudinal axis of the fastening clip assembly.
The fastening clip assembly may include a lead-in nose and an annular collar. In at least one embodiment, the central beam provides a bracing support between the lead-in nose and the annular collar. The bracing support resists crushing. The fastening clip assembly may also include an annular seal secured to the annular collar.
Certain embodiments of the present disclosure provide a securing system that may include a component having a round opening, and a fastening clip assembly secured to the component. The fastening clip assembly may include four retaining legs that directly contact portions of the component proximate to the round opening to provide four points of contact with the component, and a central pedestal including a central beam and two angled retaining beams extending from the central beam. The two angled retaining beams exert a triangular retaining force into the component.
Before the embodiments of the disclosure are explained in detail, it is to be understood that the disclosure is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The disclosure is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting. The use of “including” and “comprising” and variations thereof is meant to encompass the items listed thereafter and equivalents thereof as well as additional items and equivalents thereof.
Embodiments of the present disclosure provide a fastening clip assembly that may be integrally formed and molded as a single piece. The fastening clip assembly may provide four points of retention with respect to a component, such as a panel. Also, the fastening clip assembly provides a triangular retaining force that allows for efficient insertion into and secure retention within a round opening of a panel.
Embodiments of the present disclosure provide a fastening clip assembly that exerts a triangular retaining force into a component, such as into a round opening of a panel. The fastening clip assembly is configured to be retained within a round opening of a component, such as a panel. The fastening clip assembly provides four points of retention that are strengthened and buttressed by the triangular retaining force, thereby providing equal retention from all directions of loading. The fastening clip assembly may also include a central beam (such as a central pedestal, post, or the like) that prevents crushing if the fastening clip assembly is misaligned with an opening of a panel. Embodiments of the present disclosure may be used to attach automotive interior door panels to sheet metal, for example.
The panel-engaging retainer 102 includes a beveled lead-in nose 110 that is configured to guide the panel-engaging retainer 102 into a round-opening of a component, such as a panel. Four retaining legs 112 extend downwardly from the lead-in nose 110 and/or an end of a central pedestal 122 at an outwardly-flared angle. Each leg 112 includes a flexible root 114 that connects to the lead-in nose 110. The root 114 connects to a downwardly and outwardly angled (with the outward spread increasing from top towards bottom, as shown) extension beam 116, which, in turn, connects to an inwardly-canted ramp 118 at a lower distal end. The ramps 118 inwardly-cant toward a central longitudinal axis 120 of the fastening clip assembly 100. The four retaining legs 112 are regularly spaced about the central longitudinal axis 120 of the fastening clip assembly 100.
A central pedestal 122 extends downwardly from the lead-in nose and connects to a center of the annular collar 104. The central pedestal 122 may be centered about the longitudinal axis 120 and may generally be aligned with the central post 108.
The annular collar 104 includes a base 124 having an upstanding angled rim 126 extending upwardly and outwardly from the base 124. An annular seal may be secured to the rim 126.
The central pedestal 122 includes a central beam 129 and two retaining beams 130 that downwardly and outwardly cant from the central beam 129. Each of the retaining beams 130 downwardly extend from the central beam 129 at an angle θ. As such, the retaining beams 130 form a triangular structure having an apex 132 at the point where each connects to the central beam 129. Each of the retaining beams 130 forms a side of the triangle, with a base of the triangle being an imaginary line 134 extending between exposed distal ends 136 of the retaining beams 130.
With continued urging in the direction of arrow 206, the legs 112 slide over the interior edges 208. As the legs 112 slide over the interior edges 208, the legs 112 inwardly pivot about the roots 114, thereby compressing toward one another. With continued urging in the direction of arrow 206, the inwardly-canted ramps 118 slide over the interior edges 208, and the legs expand outwardly back towards initial positions, as the legs 114 outwardly pivot about the roots 114.
The panel 202 is therefore compressively sandwiched between the ramps 118 and the annular seal 128 (or, alternatively, the angled rim 126, shown in
The four legs 112 provide four points of contact between the fastening clip assembly 100 and the panel 200. In particular, the ramps 118 of each of the four legs 112 directly contact the interior edges 208 of the round opening 202 of the panel 200.
As an extraction force is applied in the direction of arrow 180, the retaining beams 130 exert a triangular resisting force that resists the extraction force. As such, the retaining beams 130 exert a triangular retaining force into the panel 202. The triangular retaining force allows for a low insertion force and a high extraction force in relation to the round opening 200. As such, the fastening clip assembly 100 may be quickly and easily secured to the panel 202, but difficult to inadvertently extract. Secure retention is achieved by the four retention legs 112, which may equalize all angles of extraction load.
The ramps 118 provide inwardly-canted surfaces that allow for the fastening clip assembly 100 to be removed, if desired, and reused. For example, the ramps 118 provide smooth, angled surfaces that allow for desired removal and reuse, in stark contrast to structures that hook or latch onto the panel that may then snag and break when a removal force is exerted into the fastening clip assembly.
Additionally, the central pedestal 122 protects the fastening clip assembly 100 from being crushed if the fastening clip assembly 100 is misaligned during installation. The central pedestal 122 provides a bracing support between the lead-in nose 110 and the collar 104 that prevents, minimizes, or otherwise reduces the possibility that the fastening clip assembly 100 may be crushed or collapse upon itself.
