A fence structure comprising:
- a post means having an elongate configuration with an interior space extending substantially along the length of said post means, said post means having at least one rail mounting alcove formed within a side wall portion of said post means, said post means having a threaded bottom mounting end portion, said post means being formed of a plastic material to have a predetermined rigidity and tactility and tensile strength, said post means having a predetermined exterior surface characteristic;
- a post mounting spike comprising a downwardly projecting spike means, an intermediate disc and a upwardly projecting member having means with internal threads for matingly receiving the threaded bottom mounting end portion of said post means, said post mounting spike being formed of a plastic material to have a predetermined rigidity and tactility and tensile strength;
- A rail means having an elongate configuration with an interior space extending substantially along the length of said rail means, said rail means having a mounting end member at each end thereof each configured for being receivably mounted within a respective rail mounting alcove, said rail means being formed of a plastic material to have a predetermined rigidity and tactility and tensile strength, said rail means having a moulded-in exterior surface characteristic.
A post and rail structure having particular utility for erecting a fence structure on a parcel of land with the fence structure being exposed to climatic and soil environmental conditions, comprising:
- a post member formed from a plastic like material to have a predetermined rigidity and elasticity, said post member having an upper post section and a ground support member, said ground support member being configured for being mountable within a portion of the parcel of land for supporting said upper post section generally in a vertical disposition upwardly from the parcel of land, said upper post section having rail support means, said post member having a predetermined integrally formed configuration and exterior surface finish, said upper post section comprises a generally square shaped hollow elongate beam being open at a top end and having an external threaded male portion at a bottom end, said ground support member comprises a spike like portion configured for being insertable into the soil and having a grass prevention disc configured for abuting a portion of the soil surface about said upper post section and having an upper nut section with an opening having internal thread members for matingly receiving said threaded male portion of said upper post section whereby said post member being vertically mountable, said upper post section and said nut section having a moulded-in surface finish simulative of a stained/painted wood surface;
- and
- a rail member formed from a plastic material to have a predetermined rigidity and elasticity, said rail member having an elongate body section and two rail mounting end caps each affixable at a respective end of said body section and being configured for being receivably mountable to said rail support means, said rail member having a predetermined integrally formed configuration and exterior surface finish, said body section having a generally square hollow beam shape being open at both ends, said rail mounting end caps each comprising a square plug section dimensioned for being inserted within a respective open end of said body section and an intermediate section and a square peg section dimensioned for being mountingly received by a respective rail support means.
