This invention is for a canopy construction for use over doorways, and relates particularly to a canopy formed of a plurality of louvre elements.

Our invention has for its Object to provide an over-the-door canopy of novel, economical con- 1 struction, which, however, is of good appearance, strong construction capable of withstanding high winds, but which is relatively light. It can be constructed in sheet metal shops without expensive equipment, and is relatively light and easily set up.

Our invention provides a canopy having a covering formed of overlapping alternately reversed louvres of channel section, preferably but not necessarily spaced to afford ventilation, and provide door-step protection from sun, rain and SHOW.

The invention may be more fully understood by reference to the accompanying drawing, in which:

Fig. l is a front elevation of the canopyframe with the cover removed;

Fig. 2 is a top plan view thereof Fig. 3 is a typical section, such as one taken on line III-III of Fig. 2, showing one of six like joints in the assembly;

Fig. 4 is a perspective view of the peak or top center of the frame;

Fig. 5 is a front elevation of the canopy;

5 Claims. (Cl. 26-575) Fig. 6 is a transverse vertical section in the plane of line VI-VI of Fig. 5; and

Fig. 7 is a similar section in the In the drawings, reference may first be made to Figs. 1 and 2, wherein it will be seen that the frame of the canopy is comprised of three sloping frame members converging to a central apex. Two of these members, 2 and 3, are of equal length, similar construction, and are in the same plane. They meet at the apex 4. The third membeer is in a plane at right angles to the first, sloping downwardly and forwardly from the apex. It has its upper end joined to the members 2 and 3 by angle cleats 6. All three frame members, 2, 3' and 5, are preferably formed of light structural shapes, such as may be made from heavy plane of line members 2, 3 and 5. The members It) and I I are similar to 8 and 9, but have a smaller radius of curvature and join the three sloping frame members intermediate the ends thereof. Looking down on the frame, these two sets of curved members provide concentric semi-circles.

Each of the curved frame members is preferably of the section shown in Fig. 3, being a structural section of generally 2 form of a shape such as can be made from heavy gauge sheet metal. The section so formed has a vertical web I2, an angular bottom flange I3, and a sloped upper flange I4. The curved members are secured to the sloped frame members by means of angle elements or cleats I5, which are riveted to the sloping frame members and to the vertical portions I2 of the curved members. There is a joint similar to that shown in Fig. 3 at each end of each curved member, so that there are eight such joints in all.

- The flanges I l of each of the curved members are provided with regularly-spaced notches I6 opening downwardly from the upper edge of the flange l4, these notches being clearly shown in Figs. 1 and 2. The ones along the upper or inner curved members are spaced more closely than the ones in the outer or lower curved members, and these notches are for the purpose hereinafter described.

The cover of the canopy is comprised of sheet metal channels I! and I8, the channels I! having upwardly-turned flanges, and the channels I8 having downwardly-turned flanges, the flanges being designated II' and'I8' respectively. These channels l1 and I8 decrease in width from the bottom toward the top. Each is provided with a vertically-turned valance portion, the valance portions for the channels I I being designated Ila, and those for the channels I8 being designated I8a. Because of their taper, all of the channels converge toward the apex 4 of the frame.

The channels I! are spaced from one another, and the channels I8 are in staggered relation to the channels I'I, so as to form a covering for this space. The depending flanges I78 overlap, but are spaced from the upstanding flanges II, leaving a passageway for the circulation, of air through the space between thechannels I! and out between these flanges. At the same time the flanges overlap sufliciently to exclude all direct rays of the sun, even when the sun is at a very low angle, and the channels also exclude the winddriven rain. Additionally, the flanges I? prevent rain which is flowing down the channels from escaping laterally into the spaces between the channels. The channels I8 are supported in the above described relation to the channels I] by means of cleats l9 having an upstanding leg 20 riveted to the flanges l8 and a horizontal base 2| which rests on the bottom of the channel ll. These cleats are so spaced at two points along each of the louvres or channels, that in the as sembly they will be positioned directly over the flange 14 of the curved sections as is clearly shown in Fig. 7. The cleats l9 are held in place by Sheet metal screws 22 that are received in the slots I6, pass through openings formed in the bottoms of the channels I1, and pass through openings in the base portions 2! of the cleats l9. The slots IS in the curved frame members'therefore serve to receive the shanks of the sheet metal screws 22, while the heads of the screws, being of a diameter greater than the width of the slots, lap und r the flanges I 4 and prevent relative vertical movement of the screws and the parts attached to the screws. The base portions 2 i must be pulled down tight enough against the bottoms of the louvres or channels I! to prevent rattling or looseness: of the upper louvres, and tight enoirgh to hold the lower channels or louvres l1 against the flanges M of the curved supports. By having the screws 22 in non-threaded engagement with the flanges [4, i. e., by having them in the openings t6, the sheet metal screws will draw the parts together, whereas if the screws were threaded through three thicknesses of metal, the parts might not be uniformly pulled together into tight relation, one part binding against another. Also this arrangement enables the screws to be temporarily inserted to hold the lower louvres in place, after which the upper louvres may be applied. It will be noted that the weight of the parts in such that they naturally tend to slide downwardly, so. that there is no danger of the screws 22 slipping out of the notches or slots l6.

The upper ends of the louvres terminate short of the apex 4 of the frame, and a half conical cap piece 23 is fitted over the upper ends of the louvres and secured thereto by means of sheet metal screws 24, or other fastening means. Cap piece 23 adds an ornamental and finished appearance to the canopy, as well as serving to effectively close the opening. which would otherwise exist, due to the fact that it is impractical to carry all of the converging louvres up to a sharp point.

In use, the frame shown in Figs. 1 and 2 is first assembled. Normally this is done at the sheet metal shop where the canopy is produced, but the parts may be shipped in a knocked-down condition and assembled in the field, in which cases sheet metal screws or bolts and nuts may be employed in making the joints shown in Figs. 3 and 4 instead of the rivets as shown.

When the frame is assembled, anchoring studs are positioned in the wall of the building on which the canopy is to be hung in proper position to engage the key slots '1. The frame without the covering is then hung on the building and caulking may be applied against the wall of the building where the wall-engaging frame members 2 and 3 lie against the base of the building. This caulking serves to deflect any water that may run down the face of the building. Thereafter the louvres are applied in a manner previously indicated, and finally the cap piece 23 is secured in place. and additional caulking maybe put along the face of the building and the edges of the cap piece 23 where they contact the building.

Our canopy as thus constructed is of novel appearance. It is architecturally compatible wit the doorways of most buildings. It is relatively light aluminum, preferably being used throughout. Other materials, includin plastics, may be used in the construction of the frame or for the louvres. The louvres can be secured in place firmly and quickly without the use of tools after the frame is erected. As a matter of fact, it is not difficult for the home owner to purchase the canopy in knocked-down form and intall it himself.

While we have illustrated and described a certain specific. embodiment of our invention, it will be understood that. various changes and modifications may be made in the detailed construction and arrangement of parts, all within the contemplation of our invention.
