Benefits of technology

[0008]The columnar blocks are provided with at least one interlocking element that permits a positive connection between courses of the blocks when the interlocking element is received in an overlying block. In one embodiment, the blocks interlock when there is a 90 degree rotation about a vertical axis of each block with each course. Also, these blocks may be placed over a pipe that is anchored into the ground. The core and the interlocking elements may be shaped to accommodate such a pipe. The columnar blocks can be used to construct a column with a natural stone-like appearance or smooth appearance depending upon which type of block is used. This building block system is designed to be easy to install and structurally sound.
[0010]The sides of the columnar block are provided with recesses into which fit the stacking blocks. The resulting block system is easy to install and structurally sound. The interlocking system makes the use of construction adhesive and other forms of mortar unnecessary, though such may still be used.

Problems solved by technology

Columnar structures used for decoration or as support for fence panels, gates or other such structures have required a considerable amount of skill and effort to erect.

Embodiment Construction

[0035]In this application, “upper” and “lower” refer to the placement of a columnar block in a column and a stacking block in a fence panel. The lower or bottom surface of blocks is the surface that faces the ground. Subsequent courses are formed by stacking blocks so that an interlocking element, projection, or “tongue” from one block fits into an indentation, void, or “groove” of an overlying block. “Top” and “bottom” surfaces are defined as those most conventionally used for these blocks, however, the blocks can be used with tops and bottom reversed.

[0036]The blocks of this invention may be made of a rugged, weather resistant material, such as concrete, especially if the columnar structure is constructed outdoors. Other suitable materials include plastic, reinforced fibers such as fiberglass, wood, metal and stone. Rather than being formed of a solid mass of material, the blocks may be hollow. That is, the blocks have the desired dimension, texture, and characteristics, but are h...

Abstract

A system of columnar blocks and stacking blocks interlock with each other in the construction of a pilaster or column and a fence panel, respectively, for use in a fence. The columnar blocks are generally square and the stacking blocks are generally rectangular. The columnar block faces may contain one or more slots to give a column an appearance of a masonry joint. Blocks have at least one interlocking element that permits a positive connection between courses of the blocks when the interlocking element is received in an overlying block.

Description

[0001]This application is a continuation of U.S. Ser. No. 11 / 117,640, filed Apr. 28, 2005, which claims the benefit of provisional application Ser. No. 60 / 566,590, filed Apr. 29, 2004, the contents of each of which are hereby incorporated herein by reference.FIELD OF INVENTION[0002]A system of interlocking modular blocks for forming fence columns and fence panels is described.BACKGROUND OF THE INVENTION[0003]Columnar structures used for decoration or as support for fence panels, gates or other such structures have required a considerable amount of skill and effort to erect. Conventional systems use mortared masonry blocks. Columns or pillars also have been made from stone, but this requires skilled craftspeople to ensure proper structural completion.[0004]Modular blocks have also been used to build columns or pillars. Such blocks can be installed without special skill. The advantages to such blocks are that they are a convenient size to handle, a consistent size, and installation co...
