In conjunction with above object, it is also a highly significant object of the invention thatthevventing of the interior of the roof is effectedin a manner-which provides for a full protection of the interior.
Other advantages of the invention reside in the provision of a ridge cap which is attractive in appearance, easy to install, capable of economical manufacture, and long lasting under all weather conditions.
Basically, the objec'tsof the invention are achieved through the provision of an angularly formed cap molded of glass fiber reinforced polyvinyl chloride and including an elongated central peak and a pair of oppositely inclined side panels depending therefrom. A.
transverse passage is provided through the cap with the passage in turn communicated with the interior of the cap, and hence the interior of the roof, through a pair of lateral baffled or labyrinth forming air paths. The cap, for simplification of the manufacture thereof, can be formed in two separate sections.
Other objects and advantages of the invention will become apparent from the following more detailed description of the invention and the accompanying drawings in which: 1
FIG. 1 is a partial perspective view. of the ridge portion of a roof with a series of the ridge caps of the instant invention installed thereon;
FIG. 2 is an exploded perspective view of the two components of the ridge cap;
FIG. 3 is an enlarge longitudinal cross sectional view through the ridge cap; and
FIG. 4 is a transverse cross sectional view taken substantially ona plane passing along line 4-4 in FIG. 3.
Referring now more specifically to the drawings, reference numeral is used to generally designate the ridge cap comprising the invention. As will be appreciated from FIG. 1, a series of the ridge caps. ltl areapplied along the full, or at least a major portion of the ridge 12 of a roof, the ridge 12 having a cap underlying air passing slot 14 either cut therein subsequent to the construction of the roof or defined therein as the roof is being constructed.
The ridge cap 10 consists basically of a pair of substantially planar elongated side panels 16 oppositely downwardly inclined from an elongated central peak 18, the inclination or pitch of the panels 16 generally following that of the pitched roof sections 20 which combine to define the roof ridge 12. In order to provide for a convenient end overlap of the relatively rigid cap 10, one end of each cap is provided with a downstepped offset 20 which is overlapped by the opposite smooth end of an adjacent ridge cap 10, the offset of the edge portion 20 being approximately equal to the thickness of a panel 16 whereby a smooth continuity is provided between the adjacent ridge caps 10. It will also be noted that in the overlapping end of the ridge cap 10 appropriate countersunk nailing bosses 22 are provided fora securing of the caps 10 to the underlying roof structure, the cap panel 16 normally overlying the upper course of .roofing shingles 24 as illustrated in FIG. 1.
- A transverse passage 26 is provided through each ridge cap 10 centrally along the length thereof and downwardly spaced from the peak 18. This transverse passage 26 opens outwardly through equilateral triangular openings 28 provided in each of the panels. The base of the passage 26 is closed by a horizontal panel 30 which extends between and is integrally formed with the inclined panels 16.
At each of the opposed sides of the passage 26 a baffle defining tortuous or labyrinth air flow path 32 is formed. Each path 32 is formed by a first or inner vertical baffle or partition 34 extending downwardly from the peak 18 and in continuous contact with the opposed panels 16 to a point slightly above the passage base panel 30 leaving a first lower restricted opening 36.
A second outer vertical partition of baffle 38 parallels each baffle 34 in outwardly spaced relation thereto and extends upwardly from the passage base panel 30, in engagement with the opposed inclined panels 16, to a point downwardly spaced from the peak 18 and substantially above the lower edge of the corresponding baffle 34. In this manner, a second upward air flow opening 40 is provided.
As will be appreciated from FIGS. 2 and 3 in particular, the ridge cap 10 can, for manufacturing convenience, be molded in two sections, a large main section 42 and a smaller top section 44. The centrally located top section 44 includes that portion of the cap 10 which overlies the horizontal panel 30 of the passage 26 and cooperates therewith in defining the passage and the inner baffles 34.
The main section 42, to the opposite sides of the horizontal panel 30, has the panel 16 and peak, above the panel 30, and outward a short distance from the two baffles 38, stepped inwardly as at 46 a distance equal tion 44 on the main section 42 a smooth continuous surface is provided. The top section 44 will, in the finished ridge cap 10, be permanently affixed to the main section 42 to provide, in use, what can be considered a one piece ridge cap.
' Incidentally, it will be noted thatin the top section 44, the baffles 34 are inwardly set from the opposed sides of the panel portions 48 whereby, upon a seating of the top section 44 in its installed position, the desired baffle spacing is provided between the baffles 34 and 38, resulting in the aforedescribed tortuous air passages 32.
The finished ridge cap, preferably molded of fiberglass reinforced polyvinyl chloride, provides a unique means for venting an attic space or the like at the peak area of a roof. In operation, the transverse passage 26 through each ridge cap 10 acts in the manner of a venturi with the air moving therethrough creating in effect a suction so as to draw the heated air from the attic space through the baffled air path 32 to each side of the passage 26. By the same token, while the heated attic air can be easily drawn through the air path 32 for an exhausting exterior of the building and a corresponding cooling of the attic area, the action is in effect one way with no rain or the like being capable of entering into the attic area through the ventilating ridge cap.
It will be appreciated that changes and modifications may be made in the invention without departing from the scope of the following claims.
