Abstract

ABSTRACT

A combined shingle starter and vent for use along the eaves of buildings subject to rain, snow and ice storms and for pre-venting freeze back is formed of one piece of thin, bendable, sheet metal, about ten feet long, bent to form a relatively wide, inclined starter panel fitting under the lower courses of the shingles, a horizontal strut panel extending back to the fascia and containing a full length row of transverse, closely spaced parallel ventilation louvers and a downward depending attachment panel for nailing to the fascia board to prevent an unsightly, rippling of the thin metal. There is an inturned terminal flange on the attachment panel which flattens during nailing to retain a flat planar appearance of the panels of the device. An integral drip bead is formed along the front of the horizontal strut panel.

Description

It has heretofore been proposed to make a roof ven~ilating strip with six panels formed by four bends, as in United States Patent 2,954,727 to Katt of October 4, 1960. In United States Patent 1,444,821 to Wilson of February 13~ 1923, a starting strip is shown having three panels and two fold lines, but with no ventilating apertures.

SUMMARY OF THE INVENTION
The strip of this invention is similar to that of the above mentioned Wilson patent in having an inclined starter panel, a horizontal bottom strut panel, and a vertical attachment flange panel.
The invention provides a one piece shingle starter vent formed of thin bendable sheet metal, and about ten feet long said vent being of the type characterized by: a starter panel having a top wall at an angle of about 45 and a side wall that is substan-tially vertical; a horizontal strut panel connected to said side wall and having ventilation ~ouvers closely spaced therealong over the full length, and which are parallel and extend transversely and horizontally on said panel; a vertical attachment panel having an integral flange inturned from the lower edge of said attachment panel at an angle of about 45 for the full length thereof; said flange flattening into the plane said attachment panel in the areas nailed to the fascia of a dwelling and said rlange having a lower edge in tight, intimate contact with said fascia for the full length thereof when so nailed. Hitherto the nails have been found to sometimes cause unsightly outward bulges entirely along the highly visible eaves of the dwelling.
An integral, inturned flange is therefore provided along , . ~ r the terminal end of each attachment panel of each ten foot strip so that when the nails are applied to the attachment panel, close to the flange, the flange is flattened proximate the nail heads and the portion between the nail heads is in intimate, sealed, tight contact with the fascia board. Thus, instead of unsightly ripples and outward flares, or bulges, the attachment panel achieves an even, regular, slightly sinuous appearance which is decorative and not unsightly.
BRIEF DESCRIPTION OF THE DRAWING
Figure 1 is an end elevation of the combined starter and vent strip of the invention;
Figure 2 is a perspective view showing the inside of the elongated strip of Figure 1, the drip bead, the transverse louvers and the inturned flange;
Figure 3 is a view similar to Figure 1 but showing the inturned flange flattened by the nails into the fascia board of a typical dwelling; and Figure 4 is a fragmentary front elevation of a portion of the strip shown in Figure 3.
DESCRIPTION OF A PREFERRED EMBODIMENT
As shown in the drawing, the one-piece shingle starter and ventilation strip 20 is about ten feet long and preferably formed of sheet material, such as thin bendable metal, and bent to form the inclined starter panel 21, the horizontal strut panel 22 and the vertical attachment panel 23. As is clearly shown, there is low vertical side wall 15 interposed between the starter panel 21 and the strut panel 22.

~Z~L3~19 In this invention, the attachment panel 23 is provided with a full length integral inturned flange 32, bent as at 33, at an angle of about 45 and about one eighth to one quarter of an inch in width. As shown in Figo 3, when the attachment flange ¦ 23 is nailed to the fascia board 27 by nails 28, with the nails ¦ ten to ~wenty inches apart along the entire fascia board, the ¦ flange 32 is flattened as at 34, under and near each nail, and ¦ the spaces 35 between nails are pressed tightly into intimate ¦ contact with the fascia board 27. ~hus, instead o:E the bottom ¦ edges 36 of the attachment panel flaring outwardly between nails ¦ with an obvious, visible space between edge and fascia, the ¦ bottom edge 36 is turned inwardly throughout its length with no ¦ space between edge and fascia, and at most only a gentle undula-¦ tion in each space 35.
l In Fig. 3, 2~ designa~es the lower course of shingles 25 ¦ which are nailed to roof boards 26, and 31 designates the in-¦ tegral drip bead formed at the front of horizontal strut ~anel ¦ 22, A row 30 of closely spaced, parallel louvers such as 29 ¦ are integrally formed along strut panel 22, the louvers extend-ing trans ersely of the strip 20~

Claims

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:

1. A one piece shingle starter vent formed of thin bendable sheet metal, and about ten feet long said vent being of the type characterized by:
a starter panel having a top wall at an angle of about 45° and a side wall that is substantially vertical;
a horizontal strut panel connected to said side wall and having ventilation louvers closely spaced therealong over the full length, and which are parallel and extend transversely and horizon-tally on said panel;
a vertical attachment panel having an integral flange inturned from the lower edge of said attachment panel at an angle of about 45° for the full length thereof;
said flange flattening into the plane said attachment panel in the areas nailed to the fascia of a dwelling and said flange having a lower edge in tight, intimate contact with said fascia for the full length thereof when so nailed.

2. A one piece strip as specified in claim 1 wherein: said horizontal strut panel has an integral downwardly extending drip bead along the front and below the side wall of the said starter panel.
