Abstract
Description
- This application claims the benefit of application Ser. No. 61/875,848 filed Sep. 10, 2013.
- 1. Field of the Invention
- A rebar cap assembly for covering the free end of a rebar rod.
- 2. Description of the Prior Art
- Rebar cap assemblies for covering the free end of a rebar rod are generally known in the art. One such assembly is disclosed in U.S. Design Patent D654,384 granted Feb. 21, 2012 to Curt McDonald (hereinafter, the '384 patent), which discloses a rebar cap with a casing of a continuous integral metal material with a cylindrical side wall disposed about an axis and extending between an open end and a closed end with a top wall to define an interior space between the open end and the closed end for receiving the free end of the rebar rod. The rebar cap disclosed in the '384 patent also includes a shoulder extending annularly about and radially from the side wall and extending into the top wall. The rebar cap of the '384 patent further includes retaining tabs in the side wall for securing the rebar cap to the free end of the rebar rod, with the retaining tabs spaced axially from the open end and spaced circumferentially at regular intervals, and including a ramp extending into the interior space toward the closed end and terminating at a lip.
- The invention provides for such a rebar cap assembly including a disc of a continuous integral metal material defining a layer independent of the top wall of the casing and disposed upon the axis and extending to a perimeter in a cantilevered fashion radially outwardly from the closed end of the casing.
- The invention in its broadest aspect provides for a rebar cap that includes both a continuous integral metal casing and a continuous integral metal disc, which may be manufactured independently. The combination of the metal casing and metal disc allows the rebar cap of the subject invention to be inexpensively manufactured when compared with other rebar caps, such as those of cast metal. The separately manufactured casing and disc also allows them to be constructed of different materials and/or materials having different properties, such as thickness or treatment. This construction allows each of the casing and the disc to be independently optimized for desirable characteristics, such as strength against bending or the ability to be drawn to a formed shape.
- Other advantages of the present invention will be readily appreciated, as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
-
FIG. 1 is a perspective view of the closed end of the casing of the subject invention. -
FIG. 2 is a perspective view of the open end of the casing of the subject invention. -
FIG. 3 is an exploded perspective view of a rebar cap assembly with a flat disc, shown separated from the casing. -
FIG. 4 is a perspective view of a rebar cap assembly having a flat disc, showing the open end of the casing. -
FIG. 5 is a perspective view of a rebar cap assembly showing a disc with a dome shape covering the casing. -
FIG. 6 is a perspective view, showing the open end of the casing of a rebar cap assembly having a disc with a dome shape. -
FIG. 7 is a perspective view of a rebar cap assembly showing a disc with corrugations covering the casing. -
FIG. 8 is a perspective view, showing the open end of the casing of a rebar cap assembly having a disc with corrugations. - Referring to the Figures, wherein like numerals indicate corresponding parts throughout the several views, a
rebar cap assembly 20, for use in connection with a rebar rod with a free end, is generally shown inFIGS. 3-8 . The rebar cap includes ametal casing 22 and ametal disc 24 with a surface area larger than the free end of the rebar rod alone. There are many possible uses for therebar cap assembly 20. Therebar cap assembly 20 may be used as a marker, such as for surveying land, with the disc providing increased visibility and providing a surface for identifying text or other symbols. Therebar cap assembly 20 may also be used as a safety cap to protect against potential hazards from an exposed free end of a rebar rod such as impalement. It should be appreciated that the above uses are merely examples and are not intended to be limiting. - The
rebar cap assembly 20 includes acasing 22 of continuous integral metal material generally indicated inFIGS. 1-8 . Thecasing 22 has aside wall 26 with a cylindrical shape disposed about an axis A to define aninterior space 32 extending between theopen end 28 and the closedend 30 for receiving the free end of the rebar rod. The closedend 30 includes atop wall 34 having a first diameter D1. Theside wall 26 of thecasing 22 features ashoulder 36 extending annularly about and radially from theside wall 26 and extending into the closedend 30. As a result of the process of forming thecasing 22, thetop wall 34 may include acircular depression 38 centered upon thetop wall 34. - The
side wall 26 has anouter surface 40 with a plurality ofretaining tabs open end 28. Theretaining tabs interior space 32 of thecasing 22, the rebar rod is secured in thecasing 22 by theretaining tabs retaining tabs first retaining tab 42 with afirst ramp 46 extending inwardly toward theopen end 28 and terminating at a first lip 48. Theretaining tabs retaining tab 44 with asecond ramp 50 extending inwardly toward the closedend 30 and terminating at asecond lip 52. Theretaining tabs second lip 52 connected together. Alternately, theretaining tabs second lip 52. - The
rebar cap assembly 20 also includes adisc 24 of continuous integral metal material, generally indicated inFIGS. 3-8 . Thedisc 24 has a circular shape defining a layer that is independent of thetop wall 34 of thecasing 22. Thedisc 24 is disposed upon the axis A and extends to acircular perimeter 54 in a cantilevered fashion radially outwardly from the closedend 30 of thecasing 22. Thedisc 24, having a relatively larger diameter than thecasing 22, functions to distribute the weight of a person falling upon the free end of the rebar rod for protection against impalement. The relatively large diameter of thedisc 24 also increases the visibility of the cap and provides a surface for identifying text or other symbols. - The combination of the
metal casing 22 and themetal disc 24 allows therebar cap 20 to be left on a rebar rod when concrete is poured around the rebar rod and rebarcap 20. Rebar caps made of non-metals such as plastic must be removed before concrete is poured to prevent the hardened concrete from being weakened by their presence. - A bond 56 is sandwiched between the
top wall 34 of thecasing 22 and the layer of thedisc 24 for securing to thedisc 24 to thecasing 22. The bond 56 may be formed of a resistance weld or any other suitable connecting means. -
FIGS. 3-4 show an embodiment of therebar cap assembly 20 wherein thedisc 24 is flat. -
FIGS. 5-6 show an alternate embodiment of therebar cap assembly 20 wherein thedisc 24 is dome shaped. -
FIGS. 7-8 show an alternate embodiment of therebar cap assembly 20 wherein thedisc 24 has aface side 58 opposite the closedend 30 including a plurality of corrugations 60 for strengthening thedisc 24. - The corrugations 60 include a first
annular indentation 62 defining a second diameter D2 which is longer than the first diameter D1 of thetop wall 34 to define a flatcentral region 64 of thedisc 24 for receiving thetop wall 34 of thecasing 22. A secondannular indentation 66 is disposed concentrically about the firstannular indentation 62. The corrugations 60 also include a plurality oftroughs 68 that extend radially outwardly from the firstannular indentation 62 to theperimeter 54. - Obviously, many modifications and variations of the present invention are possible in light of the above teachings and may be practiced otherwise than as specifically described while within the scope of the appended claims. That which is prior art in the claims precedes the novelty set forth in the “characterized by” clause. The novelty is meant to be particularly and distinctly recited in the “characterized by” clause whereas the antecedent recitations merely set forth the old and well-known combination in which the invention resides. These antecedent recitations should be interpreted to cover any combination in which the inventive novelty exercises its utility. The use of the word “said” in the apparatus claims refers to an antecedent that is a positive recitation meant to be included in the coverage of the claims whereas the word “the” precedes a word not meant to be included in the coverage of the claims. In addition, the reference numerals in the claims are merely for convenience and are not to be read in any way as limiting.
