Abstract
A fence construction which utilizes a plurality of constituent rail and post members configured to facilitate assembly and erection of a fence. The rail and post members are formed from a plastic material to provide a virtually maintenance free fence structure which is relatively imperishable.
 
Claims
We claim:

1. 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.



Description
FIELD OF INVENTION

The present invention relates to fences and, more particularly, to a rail type fence having assembly means to facilitate erection of the fence and for the provision of a rail fence which is relatively imperishable.

BACKGROUND OF THE INVENTION

The fences exemplified in the prior art typically utilize wood posts and rails, whose exterior surfaces are generally stained or painted in an effort to retard decay or rotting.

Unfortunately, even with frequent staining or painting, wood type fences have the tendency of developing splits which expose the interior surfaces of the wood and, thereby, exacerbates rotting.

Decay of such wood fences is most prevalent at and about the portion of the post members which are burried in the earth to provided the vertical support for the fence.

The obvious disadvantage of the prior art fences, in addition to those noted above, are that the wood posts and rails may develop surface splinters which, in turn, can cause injuries; and that periodic expensive maintenance and replacement of rotted members are required. It is to be noted that another disadvantage exists with the prior art post and rail wood fences, that being that internal rot may have weakened a post or rail such that a potential exists for serious injury with such member suddenly breaking under the weight of an unsuspecting person who may have sat or rested on said (internally) rotted fence member.
 
  A protective covering assemblage is releasable secured to a post extending from the ground. Protection means are mounted on and supported by a top portion...  A barrier comprises posts, an impact-absorbing rail, and a pretensioned steel cable extending in the longitudinal direction of the barrier. The steel cable...
