Releasable fastening device
View Patent ↗An assembly having a device for releasably fastening a first component to a second component includes a device body, a first fastener extending from the device body and operable to attach the device body to the first component, and a second fastener extending from the device body and adapted to attach the device to the second component. When a force of greater than a predetermined amount is applied to the second component, the first fastener detaches from the first component without damaging the first component. Preferably, the first component is a vehicle headlamp or taillamp assembly and the second component is a bumper fascia. The first and second fasteners of the device body accurately position the fascia relative to the headlamp assembly and securely hold the fascia at a location near a lamp lens.
1. An assembly comprising:
a bumper fascia including a fascia flange;
a lamp assembly mounted adjacent to the bumper fascia and including a lamp flange having an end and a finger spaced from and defining a recess with the lamp flange; and
a device including an intermediate arm; an upper arm extending from the intermediate arm in a non-parallel direction and including a first end, an opposed second end, a first fastener located adjacent to the first end and adjacent to the end of the lamp flange and having a projection releasably secured in an aperture of the lamp flange, and a radius on the second end that extends into the recess and is in releasable engagement with the finger; and a second fastener including an attachment arm extending from the intermediate arm and having a projection secured in an aperture of the lamp flange;
whereby when a force less than a predetermined amount is applied to the bumper fascia, the bumper fascia, the lamp assembly and the device will remain secured together, and when a force greater than the predetermined amount is applied to the bumper fascia, in a predetermined direction, the radius will release from the finger and the device will disengage from the lamp assembly.
2. The assembly of claim 1 wherein the device includes a lower arm extending from the intermediate arm and spaced from the upper arm and the attachment arm, the lower arm and the attachment arm define a channel therebetween, the second fastener includes a projection extending from the attachment arm toward the lower arm, the fascia flange includes an aperture, and the projection is releasably engaged in the aperture for releasably securing the second fastener to the fascia flange.
3. The assembly of claim 1 wherein the lamp assembly includes a lens and a housing, the lens being located adjacent to the bumper fascia, and the lamp flange and the finger extending from the housing.
4. The assembly of claim 1 wherein the lamp flange includes an aperture and the upper arm includes a projection extending therefrom that is releasably engaged with the aperture, and wherein the first fastener extends from the upper arm and includes a return flange extending parallel to and spaced from the upper flange to define a channel, the lamp flange releasably mounted in the channel.
5. The assembly of claim 1 wherein the upper arm is parallel to and secured against the lamp flange.
6. The assembly of claim 1 wherein the lamp assembly is a headlamp assembly.
7. The assembly of claim 1 wherein the lamp assembly is a tail lamp assembly.
8. An assembly for releasably fastening a lamp assembly to a bumper fascia, the assembly comprising:
the lamp assembly, including a lamp flange extending therefrom and a finger spaced from and defining a recess with the lamp flange;
the bumper fascia, including a fascia flange extending therefrom; and
a device having an intermediate arm; an upper arm extending from the intermediate arm in a first direction that is non-parallel to the intermediate arm; a first fastener extending from the upper arm and including a return flange extending parallel to the upper arm, the upper arm and the return flange defining a first channel, the lamp flange releasably mounted in the first channel; a radius located opposite the first fastener extending into the recess and being in a releasable engagement with the finger; a lower arm extending from the intermediate arm in a second direction that is opposed to the first direction, the lower arm extending parallel to and spaced along the intermediate arm from the upper arm; and a second fastener including an attachment arm extending from the intermediate arm in the second direction parallel to and spaced from the lower arm, the attachment arm and the lower arm defining a second channel, the fascia flange mounted in the second channel;
whereby when a force less than a predetermined amount is applied to the bumper fascia, the bumper fascia, the lamp assembly and the device will remain secured together, and when a force greater than the predetermined amount is applied to the bumper fascia, in a predetermined direction, the radius will release from the finger and the device will disengage from the lamp assembly.
9. The assembly of claim 8 wherein the upper arm includes a first end and an opposed second end, and the return flange is located adjacent to the first end, and the second end includes a radius portion releasably engaged with a finger extending from the lamp assembly.
10. The assembly of claim 9 wherein the first fastener includes a projection extending from the upper arm that is releasably engaged with an aperture in the lamp flange.
11. The assembly of claim 8 wherein the first fastener includes a projection extending from the upper arm that is releasably engaged with an aperture in the lamp flange.
12. The assembly of claim 8 wherein the second fastener includes a projection extending from the attachment arm that is engaged with an aperture in the fascia flange.
13. The assembly of claim 8 wherein the device includes a rib supportably extending between the intermediate arm and the upper arm.
14. The assembly of claim 8 wherein the lamp assembly includes a housing and a lens, and the first fastener is releasably attached to the housing.
15. The assembly of claim 8 wherein the predetermined amount of force for allowing the first fastener to detach from the lamp assembly is variable by varying an amount of the overlap between the second end of the upper arm and the finger.
16. The assembly of claim 8 wherein the predetermined amount of force for allowing the first fastener to detach from the lamp assembly is variable by varying a size of the radius.
17. The assembly of claim 8 wherein the lamp assembly includes lamp flange having an aperture; the device body includes an upper arm secured against lamp flange; and the first fastener includes a projection extending from the upper arm into the aperture, and a return flange extending parallel to and spaced from the upper arm to define a channel within which the lamp flange is releasably secured.
