Abstract: The invention provides a portable, collapsible sign stand assembly in which a sign is suspended from a support tube. The support tube is connected to a support base through a connecting member which includes a plurality of weakening members which cause the connecting member to fail upon impact. In other embodiments, the support tube is weakened by weakening members so as to fail upon impact. In one embodiment, the weakened portions are placed under tension.

Abstract: A vehicular barrier post includes an upper tubular portion and a lower tubular stand-off. The upper portion is joined to a rocking base having a tubular bottom portion telescopically received in the stand-off. The upper end of a tension spring is secured to the upper body portion by a pin. The lower end of the spring is attached to a tension member, such as a chain, which passes through the stand-off so as to be received in a hole in a suitable external support. The chain is pulled past the external support and when the spring is appropriately tensioned, a locking pin is passed through the chain, preventing its reverse travel through the external support. The upper body portion is allowed to freely rock about the stand-off.
