Abstract:
1. A rotating barrier having a rotating arm assembly with at least one flexible blocking arm, wherein the flexible blocking arm has opposite ends, an arm length defined between by said opposite ends and a resiliently flexible core piece having a core length extending at least over part of said arm length, wherein said core piece urges said blocking arm toward an elongate unflexed condition for blocking passage of an object through an access lane and permits resilient flexing of said blocking arm to a flexed condition in response to a collision of said blocking arm with the object in the access lane, said flexible blocking arm further being provided with a continuous flexible outer sheath enclosing said resiliently flexible core piece along said core length thereof to prevent recognition of the resilient flexibility of said blocking arm while permitting said resilient flexing of said blocking arm; the resiliently flexible core piece comprising a resilient element which permits said resilient flexing of said blocking arm to said flexed condition and urges said arm toward said unflexed condition, the resiliently flexible core piece further comprising hinged-together monolithic core bodies which are drawn together by the resilient element, the core bodies each having at least one of a projection and a recess, the projection of one of said core bodies engaging the recess of an adjacent one of said core bodies to permit hinged articulation of said one of said core bodies relative to said adjacent one of said core bodies, the core body at one end of the resiliently flexible core piece having only said projection and the core body at the opposite end of the resiliently flexible core piece having only said recess and the core bodies disposed intermediately therebetween each having said projection and said recess which are fixed relative to said core body and hingedly engage adjacent said core bodies on opposite sides thereof.
