초록 ▼

An assembly for supporting a sign post or the like which releases the same upon impact by a vehicle includes a lower support member connected to a stationary footing and an upper support member fixedly connected to the post. The upper support member is releasably connected to the lower support member by means of breakaway coupling members which have weakened portions between the support members. Each coupling member is adapted to be severed upon application of a combination of excessive bending moments and axial forces thereto. The upper support member has load concentrating elements projecting therefrom which cooperate with the coupling members to equalize the bending moment produced thereto only upon application of wind load or the like to the signpost or the like at a point remote from the upper support member. The assembly compensates for or negates the effect of the bending moment produced from wind loads while impact of the post by a vehicle proximate to the upper support member is not compensated for by the assembly and readily releases and displaces the post to minimize damage to the automobile and injury to its occupants.

A breakaway assembly for supporting an elongate post or the like at one end thereof, which post generally defines an axis and may be subjected to transverse forces and negligible vertical forces along a predetermined direction at the other end thereof and to transverse forces proximate to the supported end, the assembly comprising: spaced upper and lower support means, said support means includiNg means for fixedly anchoring the same to a support surface, said upper support means being fixedly connected to the post and having at least two portions thereof spaced from each other along a line substantially parallel to said predetermined direction, each of said spaced portions being provided with at least one opening therethrough, two openings, each on a different one of said associated spaced portions, defining a pair of associated openings, said openings having axes substantially parallel to the axis of the post, said spaced portions having opposing surfaces respectively facing toward and away from said lower support means; a coupling member associated with each opening in said spaced portions, each coupling member extending between an associated spaced portion and said lower support means, each coupling member being provided with a weakened portion disposed between said upper and lower support means and being fixedly connected at one end to said lower support means, the other end of each coupling member extending through an associated opening and defining two spaced bearing surfaces each of which faces a different one of said opposing surfaces of said spaced portions; and protuberance means joined to and projecting from each of said opposing surfaces of said spaced portions, one of said protuberance means being disposed between one of said opposing surfaces and as associated bearing surface of a coupling member and being in abutting relationship against the latter, and another protuberance means being disposed between the other of said opposing surfaces and an associated bearing surface of a coupling member and being in abutting relationship against the latter, each protuberance means being eccentric relative to the axis of an associated opening to dispose the same inwardly in the space between a pair of associated openings.
