Description
BASE MOLD FOR CONCRETE POST
FILED OF THE INVENTION
The present invention relates to a mold and more particularly, to a mold suitable for forming a base for concrete posts.
BACKGROUND OF THE INVENTION
Concrete inground posts are installed to serve as supports for exterior structures such as decks, porches and out buildings. In a manner similar to a house foundation, they require a footing or base in order to disperse the downward force placed upon them, to stabilize them to lateral stress and in some areas to retard the action of frost heaving them upwardly.
In the art, it is a conventional practice to use a form for the posts <~.nd which form provides a round hollow manufactured paper or fiber tube. These 12' long fiber or paper tubes come in different diameters such as 6", 8" 10" etc. and are cut to the length required by the user.
A single manufactured 8" tube may in fact be 7'/2", 73/4", 8" or 8'/d " in diameter, to facilitate compact shipping by placing 7'/2 " tubes within 73/d" tubes within 8" tubes, etc.
Any base mold to be attached to a section of one of these tubes must therefore be either custom fitted to the tube on hand or have the ability to adapt to various diameters.
The present practice is that the user will build a custom fitted mold for the' base from wood. Thus it is well known for builders to construct a square of lumber ;end subsequently a plywood top is added. A hole is cut in the plywood to accommodate the tube and the box and tube are nailed together. The tube and box are then placed in the excavation and the excavation is subsequently back filled. Frequently :reinforcing rods are placed in the tube and then the tube and the base are filled with concrete to provide a one piece concrete post and base (footing).
There are disadvantages to the above arrangement. It is a very time consuming process and the joint formed where the tube meets the base tends to be somewhat weak when subjected to lateral stress at the abrupt 90° tube to box joint. A
multitude of tools and some skill are required for box fabrication.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a mold for a base for concrete posts which is lightweight, strong and adaptable to various diameter tubes.
It is a further object of the present invention to provide a mold for a base for a concrete post having a strong tapered tube to base joint.
It is a further object of the present invention to provide a mold for a base for a concrete post which is fast, economical, easy to use and requires no special tools or skill to install.
In one aspect of the present invention, there is provided a mold suitable for forming a base for a concrete post, the mold comprising an upper portion and a lower portion, the lower portion being defined by a lower sidewall and the upper portion being defined by an upper sidewalk the upper sidewall having an inwardly tapered portion, a plurality of slits formed in the inwardly tapered portion, the slits extending to an upper marginal edge of the upper sidewall.
The lower portion of the mold is larger in diameter or area than the upper portion.

The lower portion of the mold is larger in diameter or area than the upper portion.
-2-The lower portion may have many different configurations such as rectangular, oval, circular, etc. In one embodiment, the upper portion may be offset with respect to the lower portion to allow for use of the same in different environments.
The slits in the upper sidewall allow the formation of flexible flaps which can then open up to accommodate tubes of various diameters. Since the flaps press against the side of the inserted tube, they present a large contact area and which may allow the tube to be secured to the mold by means of tape, screws, clamps, etc.
The mold can be made of many different materials including, plastic, plastic composites, acrylic, fiberglass, rubber, stamped sheet metal, recycled plastic or rubber, etc.

-3-suitable for forming a base for a concrete post, the mold being designated generally by reference numeral 10.
Mold 10 has a lower portion generally designated by reference numeral 12 and which is defined by a lower sidewall 14. Lower sidewall 14 has a plurality of outwardly extending ribs 16. It will be noted that there is provided a generally horizontal portion 18 which forms a footrest for reasons which will be described hereinbelow, At the lower marginal edge of lower sidewall 14, there is provided a lower flange 20 having apertures 22 formed therein.
Mold 10 also includes an upper portion generally designated by reference numeral 24 and which is defined by an upper sidewall 26. Upper sidewall 26 has a plurality of slits 28 formed therein. Slits 28 extend to the upper marginal edge 30 of upper sidewall 26 and thus forms a plurality of flaps 32.
Use of the mold 10 is illustrated in Figures 2, 3 and 4 and thus, it will be seen that a cylindrical tube 34 may be placed therethrough and will form the mold for the concrete post which is to be poured. As shown in Figure 2, mold 10 is moved upwardly and flaps 32 separate to permit passage therethrough. Subsequently, flaps 32 are taped to cylindrical tube 34 by means of tape 36 to thus provide a complete set up for a concrete post. As shown in Figure 4, a plurality of spikes 38 may be placed through apertures 22 in lower flange 20 to secure the mold in position.
In the preferred embodiment, and as may be seen in Figure 3, there is provided an upper portion 24 offset from lower portion 12. This permits its use in misaligned excavations.
