Patent ID: 8602379

Claim:
A vehicle assembly, comprising: (a) a vehicle body having an exterior surface, an interior surface, wherein the exterior surface is substantially parallel to the interior surface, and an attachment bore extending from the exterior surface to the interior surface and defining an attachment bore length and an attachment bore diameter; (b) a tie down removably securable within the attachment bore of the vehicle body, the tie down comprising: (i) a retention body having a collar defined at a first end of the retention body and a stop portion defined at a second end of the retention body, the collar having an external collar diameter that is greater than the attachment bore diameter, the stop portion having an interior and a stop portion length that is greater than the attachment bore length such that when the stop portion is received within the attachment bore, the collar abuts against the exterior surface of the vehicle body and the stop portion protrudes from the interior surface of the vehicle body, wherein the stop portion has one or more axial slits formed along the stop portion that are in communication with the interior of the retention body, the stop portion having an external stop portion diameter sized and configured to be releasably received within the attachment bore of the vehicle body; (ii) an anchoring device moveably disposed within an interior portion of the retention body for rotational movement between a release position, wherein the stop portion defines a first external stop portion diameter that is substantially uniform in size along the stop portion length, and a restraint position, wherein the stop portion defines a second external stop portion diameter that gradually increases in size along the length of the stop portion, wherein the one or more axial slits in the stop portion allow the stop portion to transition from the first external stop portion diameter to the second external stop portion diameter; and (iii) a stop translatable along the anchoring device and engageable with the interior of the stop portion, the stop having a length, wherein the stop gradually increases in diameter along an axis extending through a longitudinal direction of the stop along the length of the stop from a first diameter to a second diameter, wherein the anchoring device is rotatable into the restraint position such that the stop is at least partially received within the interior of the stop portion to transition the stop portion into the second external stop portion diameter, and wherein when the stop portion is transitioned into the second external stop portion diameter, the stop portion resists movement of the stop as it translates along the anchoring device, and wherein the second external stop portion diameter is greater than the attachment bore diameter such that the stop portion engages the interior surface of the vehicle body to selectively define an interference fit between the collar, the stop portion, and the vehicle body when the anchoring device is in the restraint position.
