Secured Steel Reinforcing Bar ("Rebar") Safety Cap

Abstract

A safety cap for steel reinforcing bar (rebar) has an outer body with an enlarged cap and an elongated stem extending from the cap. A hole in the stem enables the safety cap to fit over the exposed end of a section of rebar. A metal insert, molded within the safety cap, prevents the rebar from punching through the safety cap if a worker were to fall onto the safety cap. The safety cap is retained on the end of the rebar so that it cannot be easily knocked off, by a pair of threaded set screws, or by a magnet positioned within the safety cap over the end of the rebar.

DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENT(S)

[0013] While various secured rebar safety caps can embody the principles of the present invention, with reference to the drawings some of the presently preferred embodiments can be described.

A First Embodiment

[0014] Referring to FIGS. 1 and 2, FIG. 1 is an external side view of a first embodiment of a secured rebar safety cap 10 embodying the principles of the present invention. A plastic (or similar material) outer body 20 comprises an elongated collar or stem 30 and an enlarged cap 40. Stem 30 has a hole 32 to receive the end of a rebar. As can be readily understood, enlarged cap 40 provides a greatly increased contact area, should someone fall onto secured rebar safety cap 10. A section of rebar 50 is shown; it is understood that the end of rebar 50 terminates in and is covered by secured rebar safety cap 10. Preferably, safety cap 10 is made of a plastic or similar material, for example molded by an injection molding process or similar process. It is to be understood that other materials may be used as well.

[0015] FIG. 2 is a cross section of the secured rebar safety cap 10 of FIG. 1. An insert 60, typically of metal formed by stamping, etc., is typically molded into plastic outer body 20. Insert 60 provides greatly increased strength and resistance to the end of rebar 50 puncturing or punching through the end of plastic outer body 20, in the event of someone falling onto the safety cap.

[0016] A key aspect of secured safety cap 10 is a means for securing same to the rebar end, in this embodiment comprising one or more, typically two, set screws 70 which may be inserted through and threadably disposed in threaded holes in plastic outer body 20, for example stem 30, or some other part of safety cap 10. As can be readily understood by known set screws in other settings, set screws 70 may be advanced by turning them and tightening them against rebar 50. Once tightened (by hand, a screwdriver, a wrench, etc. as appropriate), set screws 70 hold rebar safety cap 10 securely in place, yet can be loosened and rebar safety cap 10 removed and re-used.

A Second Embodiment

[0017] FIG. 3 is an external side view of a second embodiment of a secured rebar safety cap 100 embodying the principles of the present invention. Similar to the first embodiment, a plastic outer body 120 comprises an elongated collar or stem 130 and an enlarged cap 140. Stem 130 has a hole 132 to receive the end of a rebar. As can be readily understood, enlarged cap 140 provides a greatly increased contact area, should someone fall onto secured rebar safety cap 100. A section of rebar 150 is shown; it is understood that the end of rebar 150 terminates in and is covered by secured safety cap 100.

[0018] FIG. 4 is a cross section of the secured rebar safety cap 100 of FIG. 3. As with the first embodiment, an insert 160, typically of metal formed by stamping, etc., is typically molded into plastic outer body 120. Insert 160 provides greatly increased strength and resistance to the end of rebar 150 puncturing the end of plastic outer body 120, in the event of someone falling onto the safety cap.

[0019] A key aspect of this embodiment of secured safety cap 100 is a means for securing same to the rebar end, in this embodiment comprising one or more magnets within the body of the rebar cap, in FIG. 4 shown as magnet 170. In view of the steel (ferrous) material from which the rebar is made, magnet 170 is attracted to rebar 150, holding safety cap 100 securely in place. It is understood that the magnetic securing force can be overcome by a user, so that safety cap 100 may be simply pulled off of a rebar, then slid down onto another rebar, where the magnet will hold it in place. It is understood that while FIG. 4 shows magnet 170 positioned over the end of rebar 150, magnet 170 could be positioned wholly or partially around rebar 150, for example in the shape of a collar. Magnet 170 may be in various shapes and positions, as long as it is sufficiently close to rebar 150 to attract and hold safety cap 100 in place on rebar 150.

CONCLUSION

[0020] While the preceding description contains many specificities, it is to be understood that same are presented only to describe some of the presently preferred embodiments of the invention, and not by way of limitation. Changes can be made to various aspects of the invention, without departing from the scope thereof. For example, dimensions may be varied to suit different rebar sizes; different materials may be used; the rebar safety cap may be used to cover any exposed piece, whether rebar, steel stakes, wooden stakes for the set screw embodiment, etc.

[0021] Therefore, the scope of the invention is to be determined not by the illustrative examples set forth above, but by the appended claims and their legal equivalents.
