Abstract
A continuous round, rubberized ring is employed to produce a champher, or beveled, edge on a concrete base. Initially concrete is poured into a cylindrical form and the ring pressed into the top side of the cylindrical form. Excess cement is removed with a trowel and the cement is allowed to harden. After the cement has hardened, the form is removed and the ring stripped off leaving an attractive and safe champher on the upper edge of the base. An alternative embodiment of the ring includes a lip that can be easily gripped so the ring can be removed from the hardened concrete base. The gripping lip also prevents the ring from falling below the upper rim of the mold when the concrete is in its wet, plastic state.
Description
- This application claims the priority of provisional U.S. application Ser. No. 60/805,588 filed on Jun. 22, 2006 and entitled “Round Rubber Champhering Ring” by John Vitale, the entire contents and substance of which are hereby incorporated in total by reference.
- 1. Field of the Invention
- The invention relates to a continuous round rubber champhering ring and a method of using same to form a champher on a concrete base.
- 2. Background of the Invention
- There are a number of techniques known in the prior art for producing a champher on concrete and the like.
- U.S. Pat. No. 5,382,393 entitled “Method and Apparatus for Forming Champhered outside Corners on Concrete Products” appears to describe a segmented set of triangular shaped wooden champher forming strips located at the edges of a concrete product.
- U.S. Pat. Nos. 4,978,099 and 5,616,271 describe methods of forming champhers on the sides of concrete products using generally triangular shaped inserts.
- Of relevance, but probably of lesser importance, are the devices and techniques described in the following patents: U.S. Pat. Nos. 6,419,204; 6,698,709; 6,899,489; 6,935,607; and, 6,969,041.
- A problem in the prior art is how to easily form a champher on the upper edge of a round concrete product. Prior art techniques to cope with same have usually involved cutting a rubberized product to length. This results in poor seating and unattractive champher.
- It was in the context of the foregoing prior art problems and challenges, that the current invention arose.
- Briefly described the invention comprises a continuous, seamless round rubberized champhering ring employed to form a champher on the top leading edge of a round concrete light pole base. The ring is continuous and seamless and has a generally triangular cross-section. The outside circumference of the ring fits neatly and snugly within the top of the concrete base form. According to an alternative embodiment, the ring may include an additional lip to make it easier to grab and remove and so it will not fall below the top edge.
- The round rubber champhering ring is used in the following manner. First, concrete is poured into a round form. Second, the ring is pressed into the top edge of the “plastic” concrete so that the top portion of the ring is flush with the top of the round form. The ring fits snugly so that there is virtually no space between the edge of the ring and the inside wall of the form. Third, a trowel or similar object is used to clean off excess cement so that the top portion of the concrete is flat and flush with the top of the ring. Fourth, after the concrete is dried, the rubberized ring is removed. The result is a beautiful, uniform upper champher area on the top of a concrete light pole base. A properly formed champher is not only important from a cosmetic point of view, but also it tends to minimize damage to individuals or vehicles because it has no significant rough, or sharp, edges.
- The invention may be more fully understood by reference to the following drawings.
