Abstract
A plastic fence comprising easily interconnectable post sections including a base post section usually anchored in the ground and one or more shorter post sections capable of providing a fence of any desired height. The post sections may removably interconnect by a screw connection or a bayonet-type connection. In one embodiment individual struts connect horizontally between spaced post sections while in another embodiment panel means connect therebetween.

A plastic fence comprising;
- a plurality of like-diamter post sections each having means for interconnecting the post sections linearly in vertical array, in at least two parallel arranged groups with one secton of each group for anchoring the group in the ground,
- and means supported between the post section groups including key means extending toward each group,
- said post sections each having key slot means spacedly disposed therealong in at least two diametrically disposed sets for receiving the key means,
- said means for interconnecting comprising mating thread means of adjacent post sections including a female portion of one section and a reduced-diameter male portion of the other section,
- at least one of said key slot means of said one section being sufficiently proximate said female portion so that said male portion at least partially blocks the key slot means to prevent the key means associated therewith from disengaging from the key slot means.

A plastic fence comprising;
- a plurality of like-dimaeter post sections each having means for interconnecting the post sections linearly in vertical array and in at least two separate spaced parallel-disposed groups with one section of each group for anchoring the group,
- and filler means supported between the post section groups including key means extending toward each group,
- said post sections each having key slots spacedly longitudinally disposed therealong in two sets diametrically disposed to each other, each slot for receiving a key of the key means,
- said means for interconnecting comprising mating thread means of adjacent post sections including a female portion of one section and a male portion of the other section and with one of said portions being sufficiently proximate at least one of said key slots when assembled to prevent disengagement of said key,
- at least the top post section of a group being open to provide a means for supporting an item on the top of the fence.
