Abstract
A pluming vent cover is described herein which is easily manufactured and adapted to a roof on or off-site. A roof's pluming vent pipe requires a cover for both aesthetics and improved operation. In the preferred embodiment the pluming vent cover comprises an upper pyramidal cap, two rounded metal straps and a cone-shaped base. The operator can trim the lower ovoid continuous edge of the cone-shaped base to conform to the slope and pitch of the roof, shingles, or both. A method for producing this pluming vent cover is also described.
Claims15
A pluming vent cover comprising:
- A. a three-dimensional base, said base comprising a height and a diameter, said three-dimensional base further comprising a lower continuous edge and an upper continuous edge,
- said three-dimensional base comprising an interior surface and an exterior surface,
- B. a plurality of rounded metal straps, each said rounded metal strap comprising two ends, each said rounded metal strap further comprising an upper surface and a lower surface, a width, thickness and length, each metal strap further comprising a mid-line through said length, said length comprising the greatest dimension of each said metal rounded strap,
- C. an upper cap, said cap comprising an upper surface and a lower surface, said cap further comprising an apex and a continuous cap lower edge,
- said three-dimensional base attaching to said upper cap by said rounded metal straps, said vent cover attaching to a roof and enclosing a pipe, thereby concealing said pipe from observation,
- said three-dimensional base being approximately cone-shaped and said upper cap being pyramidal in shape,
- said lower continuous edge comprising a lower continuous ovoid edge and said upper edge comprising an upper circular continuous edge,
- said cone-shaped base further comprising a continuous longitudinal hem,
- said cone-shaped base severed from an integral metal sheet,
- said pluming vent cover comprising two rounded rigid metal straps, said first rounded metal strap attaching to said upper circular continuous edge by respective first and second strap ends, said second rigid rounded metal strap attaching to said upper circular continuous edge by respective third and fourth strap ends.

The method of assembly for a pluming vent cover comprising the steps of:
- a. severing a stiff flat metal sheet to create a hollow cone-shaped base, said hollow cone-shaped base comprising a maximum longitudinal height, an upper diameter, a lower diameter and a thickness, said hollow cone-shaped base further comprising an upper circular continuous edge and a lower ovoid continuous edge, a first sheet edge and a second sheet edge,
- b. bending said first sheet edge back upon itself and bending said second sheet edge back upon itself to produce a first longitudinal fold and a second longitudinal fold respectively, each said longitudinal fold consisting solely of smooth edges,
- c. hooking said second longitudinal fold around said first longitudinal fold,
- d. manually flattening each said longitudinal fold to create a longitudinal hem, said longitudinal hem comprising no mechanical fasteners,
- e. bending a first rounded metal strap and a second rounded metal strap to a rounded configuration, said first rounded metal strap comprising first and second respective ends and said second rounded metal strap comprising third and fourth respective ends,
- f. attaching said rounded metal straps to said upper circular continuous edge of said hollow cone-shaped base by their respective ends,
- g. severing a section from a stiff metal sheet and then severing a straight line to the center point of said section, thereby creating a first circular component longitudinal edge and a second circular longitudinal edge,
- h. forming a continuous longitudinal seam by placing said first circular component longitudinal edge and said second longitudinal edge in overlapping alignment, said continuous longitudinal seam held in place with a single seam pop rivet within first and second congruently aligned seam pop rivet apertures, said overlapping alignment creating an upper pyramidal cap,
- i. inserting four pyramidal pop rivets through corresponding pop rivet apertures within said rounded straps and said upper pyramidal cap, said pop rivets attaching said two rounded metal straps to said upper pyramidal cap, said rounded straps creating a spaced interval between said hollow cone-shaped base and said upper pyramidal cap.
