Example

[0031]FIG. 1 is a plan view of one embodiment of a folding flue according to the present invention as it would be shipped. A body [1100] is shown in its unfolded flat view. Body [1100] has vent holes [1110] cut into it.

[0032]Body [1100] has stamped or perforated or otherwise weakened fold lines [1180]. Fold lines [1180] are a narrow area of reduced strength. These fold lines [1180] are typically constructed by running a roller blade over a metal sheet thereby producing indentations and a thinned area. Here they are created by cutting slots. When a sheet having a fold line [1180] is bent, it tends to bend at the fold line [1180] and not elsewhere on the sheet.

[0033]Body [1100] has several fold lines [1180] which separate it into end panels [1140, 1150], and side panels [1160, 1170]. Each of these panels has a top tab [1120] and a bottom tab [1130].

[0034]A first connector part [1210] is attached to one end of body [1100] and a second connector part [1220] is attached to the other end ...

Abstract

The present invention relates to a folding chimney flue cap [1000] for fitting chimneys. The folding flue cap [1000] is manufactured as a flat body [1100] having an end panel [1140], a side panel [1160], another end panel [1150], and another side panel [1170], separated by fold lines [1180] between the panels. The folding chimney flue cap [1000] also includes top tabs [1120] above each of these panels. There are also bottom tabs [1130] below each of these panels. The flat body [1100] has a first connector part [1210] at one end and a second connector part [1220] on the other end. The folding flue cap [1000] may be readily shipped in its compact form and assembled into a box shape connecting first connector part [1210] to second connector part [1220]. The top tabs [1120] and the bottom tabs [1130] may be bent either inwardly or outwardly to better match the structures to which it would connect.
