Abstract

A protective cover for concrete reinforcement bars includes an elongated cylindrical collar for securing the protective cover to an exposed end of a concrete reinforcing bar, a cap which is perpendicularly attached to the collar by reinforcing ribs, and a metal seat arranged between the collar and the cap and having slots for permitting direct attachment of the reinforcing ribs from the collar to the cap.

Claims

1. A protective cover for covering an end of a concrete reinforcing bar so as to prevent injuries to an individual caused by coming into contact with the end of the concrete reinforcing bar, said protective cover comprising:

a cylindrical collar, said cylindrical collar being dimensioned to receive the end of concrete reinforcing bars of varying sizes and at least a portion of said collar having inwardly-extending and off-center fins for releasably securing the end of the concrete reinforcing bar to the protective cover;

a cap, said cap having an exposed top surface and exposed sides which are constructed so as to prevent injury to any individual coming into contact with the exposed top surface and sides and said cap having an underside which is attached perpendicularly to said collar and at least a portion of said cap including reinforcing ribs extending to at least a portion of the collar; and

a metal seat, said metal seat being disposed adjacent and beneath the underside of said cap,

whereby, in the event that an individual comes into contact with the protective cover, the individual will not be gouged, scraped or impaled by the end of the reinforcing bar.

2. A protective cover according to claim 1, wherein said metal seat covers an area which is greater than a diameter of the concrete reinforcing bar and wherein the metal seat prevents penetration of the end of the bar through said cap.

3. A protective cover according to claim 1, wherein said collar has a constant diameter.

4. A protective cover according to claim 1, wherein the inwardly extending and off-center fins flex outwardly so as to accommodate bars of varying sizes.

5. A protective cover for covering an end of a concrete reinforcing bar so as to prevent injuries to an individual caused by coming into contact with the end of the concrete reinforcing bar, said protective cover comprising:

a cylindrical collar, said cylindrical collar being dimensioned to receive the end of the concrete reinforcing bar and at least a portion of said collar having means for releasably securing the end of the concrete reinforcing bar to the protective cover;

a cap, said cap having an exposed top surface and exposed sides which are constructed so as to prevent injury to any individual coming into contact with the exposed top surface and sides and said cap having an underside which is arranged perpendicularly to said collar and at least a portion of said cap including reinforcing ribs extending to at least a portion of the collar; and

a seat, said seat being disposed adjacent and beneath the underside of said cap,

whereby, in the event that an individual comes into contact with the protective cover, the individual will not be gouged, scraped or impaled by the end of the reinforcing bar.

6. A protective cover according to claim 5, wherein said collar has a constant diameter.

7. A protective cover according to claim 5, wherein the collar includes inwardly extending off-center fins for securing the end of the concrete reinforcing bar within the portion of the collar and wherein the inwardly extending and off-center fins flex outwardly so as to accommodate bars of varying sizes.

8. A protective cover for covering an end of a concrete reinforcing bar so as to prevent injuries to an individual caused by coming into contact with the end of the concrete reinforcing bar, said protective cover comprising:

a cylindrical collar, the cylindrical collar adapted to receive reinforcing bars of varying sizes;

a cap, said cap having an exposed top surface which is constructed so as to prevent injury to any individual coming into contact with the exposed top and said cap having an underside which is attached perpendicularly to said collar and at least a portion of said cap including reinforcing ribs extending from the underside of said cap to at least a portion of the collar; and

a metal seat, said metal seat being disposed adjacent and beneath the underside of said cap,

whereby in the event that an individual comes into contact with the protective cover, the individual will not be gouged, scraped or impaled by the end of the reinforcing bar.

9. A protective cover according to claim 8, wherein said cylindrical collar has a constant diameter.
