Abstract

Claims (55)

1 . A guardrail formed of folded sheet metal comprising:

a vertically disposed face panel having a top edge, a side edge, and a front surface,

a top panel extending rearwardly from the top edge of the face panel, the top panel having a return edge opposite the top edge of the face panel,

a return panel extending vertically from the return edge of the top panel, the return panel having a back surface,

an end panel extending rearwardly from the side edge of the face panel, the end panel having the same width as the distance between the front surface of the face panel and the back surface of the return panel, the end panel including an upwardly extending upper portion,

wherein the face panel, top panel, and return panel form a U-shaped channel, the upper portion of the end panel freely received in the channel,

wherein the end panel defines a recessed portion adjacent the return panel between the upper portion and the lower portion of the end panel, the recessed portion extending to a side edge of the end panel that aligns with the back surface of the return panel;

wherein the upper portion of the end panel is configured to move between a flat state and an installed state independently from the top panel; and

wherein the top panel, return panel, and end panel are defined by folded sections of a sheet metal blank.

2 . The guardrail of claim 1 further comprising:

the face, top and return panels having end edges, and

the upper portion of the end panel including an end surface flush with the end edges of the face, top and return panels.

3 . The guardrail of claim 2 further comprising:

a bend relief disposed along the side edge of the face panel at a distance from the top edge thereof,

wherein the end panel is bent rearwardly from the face panel along the side edge at the bend relief, and

wherein the upper portion of the end panel defines a front edge, an end panel top edge, and a back edge that are spaced from the face panel, top panel, and return panel.

4 . The guardrail of claim 3 wherein:

the return panel has a bottom edge, and wherein the distance from said bottom edge to the top panel is substantially the same as the distance from the bend relief of the face panel to the top panel.

5 . The guardrail of claim 2 wherein the end surface of the upper portion of the end panel is coplanar with end edges of the face panel, top panel, and return panel.

6 . The guardrail of claim 1 wherein the top panel is disposed perpendicularly to the face panel.

7 . The guardrail according to claim 1 , wherein the top panel is continuous.

8 . The guardrail according to claim 1 , wherein the face panel is discontinuous.

9 . A guardrail comprising:

a sheet metal blank comprising a plurality of fold lines defining:

a top panel;

a face panel extending from the top panel, the face panel configured to extend perpendicular relative to the top panel;

a return panel opposing the face panel, the return panel configured to extend perpendicular relative to the top panel;

an end panel extending from a side edge of the face panel, the end panel configured to extend perpendicular relative to the face panel;

wherein the end panel defines an upper portion and a lower portion having a greater width than the upper portion;

wherein the top panel, the face panel, and the return panel are configured to define a channel;

wherein the channel is configured to receive the upper portion of the end panel;

wherein the upper portion of the end panel is configured to move between a flat state and an installed state independently from the top panel;

wherein the end panel defines a recessed portion adjacent the return panel between the upper portion and the lower portion of the edge panel; and

wherein an end portion of the return panel is configured to nest within the recessed portion of the end panel.

10 . The guardrail according to claim 1 , wherein a top edge of the upper portion of the end panel is offset from the top panel such that a gap is defined between the top edge of the upper portion of the end panel and the top panel.

11 . The guardrail according to claim 1 , wherein an end portion of the return panel is configured to nest within the recessed portion of the end panel.

12 . A guardrail formed of folded sheet metal comprising:

a vertically disposed face panel having a top edge, a side edge, and a front surface,

a top panel extending rearwardly from the top edge of the face panel, the top panel having a return edge opposite the top edge of the face panel,

a return panel extending vertically from the return edge of the top panel and parallel with the face panel, the return panel having a back surface and a bottom edge,

an end panel extending rearwardly from the side edge of the face panel, the end panel having the same width as the distance between the front surface of the face panel and back surface of the return panel, the end panel including an upwardly extending upper portion having an end surface,

a bend relief disposed along the side edge of the face panel at a distance from the top edge thereof, the end panel bent rearwardly from the face panel along the side edge at the bend relief, the distance from the bottom edge of the return panel to the top panel substantially the same as the distance from the bend relief of the face panel to the top panel,

the face, top and return panels having end edges, the end surface of the upper portion of the end panel flush with the end edges of the face, top and return panels, and

the face, top and return panels forming a U-shaped channel, the upper portion of the end panel freely received in the channel;

wherein the upper portion of the end panel is configured to move between a flat state and an installed state independently from the top panel;

wherein the end panel defines a recessed portion adjacent the return panel between the upper portion and the lower portion of the edge panel; and

wherein an end portion of the return panel is configured to nest within the recessed portion of the end panel.

13 . The guardrail according to claim 12 , wherein the top panel is continuous.

14 . The guardrail according to claim 12 , wherein the face panel is discontinuous.

15 . The guardrail according to claim 12 , wherein the upper portion of the end panel defines a front edge, an end panel top edge, and a back edge that are spaced from the face panel, top panel, and return panel.

16 . The guardrail according to claim 9 , wherein an end portion of the return panel freely nests within the recessed portion such that the end portion of the return panel is spaced from the recessed portion of the end panel.

17 . The guardrail according to claim 16 , wherein the top panel is continuous.

18 . The guardrail according to claim 16 , wherein the face panel is discontinuous.

19 . The guardrail according to claim 16 , wherein the face panel defines a plurality of apertures.

20 . The guardrail according to claim 16 , wherein the sheet metal blank further defines a cutout extending between the face panel and the end panel.
