United States Patent VENTILATED HORIZONTAL SLAT METAL AWNING Robert F. Howard, Salt Lake City, Utah Application October 18, 1954, Serial No. 462,952

Claims. (Cl. 20-575) This invention relates to metal awnings, and particularly to those whose constructions provide for passage of air therethrough for ventilating purposes.

It is a principal purpose of the invention to provide a ventilated metal awning of so-called horizontal slat construction which will afford maximum protection against the weather with minimum obstruction of light and visibility, while, at the same time, being trim and neat in styling and capable of relatively simple and economical fabrication.

An additional purpose is to incorporate, in a ventilated metal awning of horizontal slat type, the peculiarly advantageous drip-line feature embodied in the vertical slat construction of U. S. Patent Number 2,627,634 granted to R. G. Gunter on February 10, 1953, wherein an interlocking tongue and groove arrangement establishes a protective lineof drip adjacent each apertured wall portion to effectively preclude any possibility of backflow of rain run-off through the ventilating apertures.

I accomplish these purposes of the invention by a tongue and groove interlocking type of slat of special configuration, as set forth fully hereinafter. I

Further objects and features of the invention will become apparent from the following detailed description of the particular preferred specific construction illustrated by way of example in the accompanying drawing.

In the drawing:

Fig. 1 represents an end elevation of the awning construction installed, an intermediate portion being broken out for convenience of illustration;

Fig. 2, a fragmentary front elevation taken from the viewpoint of the arrow2 in Fig. 1;

Fig. 3, a similar rear elevation taken from the viewpoint of the arrow 3 in Fig. l; and

Fig. 4, a vertical section taken along the line 4-4 inFig. 3, but excluding additional intermediate portions and drawn to an enlarged scale.

Referring to the drawing:

The awning here illustrated as being typical of the invention is made up of a plurality of interlocked, horizontal slats 10, whose lengths extend along the width of the awning structure, as indicated in Figs. 2 and 3. Such slats are interlocked with next adjacent slats along their opposite longitudinal margins. Thus, the interlocks 11 extend longitudinally of the slats and transversely of the awning structure, along the width of the latter.

Each of the slats 10, except the uppermost and the lowermost, which are indicated -1 and 10-2, respectively, is of special configuration providing for a most advantageous tongue and groove interlock along its opposite longitudinal margins, as well as for firm securement to the supporting framework of the awning structure and for effective ventilation and light transmission.

The terminal slats 10-1 and 10-2 are essentially similar, except for appropriate provision for tying in with the structural framework of the awning or the building against which the awning is installed, as determined in each instance by the nature of the particular installation.

2,825,100 Patented Mar. 4, 1958 lice Each of the intermediate slats 10, which interlock with next adjacent slats along both of its opposite longitudinal edge margins, comprises a main roofing portion 10a of longitudinal strip formation, a securement strip portion 10b having its forward longitudinal margin adjoining the rearward longitudinal margin of the roofing strip portion, an upstanding apertured wall portion 10c having its lower longitudinal margin adjoining the'rearward longitudinal margin of the securement strip portion, a locking groove member 10d having its upper and rearward longitudinal margin adjoining the forward longitudinal margin of the roofing strip portion so that the mouth of the groove faces inwardly of'the slat, and a locking tongue 106' having its rearward longitudinal margin adjoining the upper margin of the apertured wall portion and the tongue proper projecting forwardly therefrom in overhanging relationship with the securement strip portion 10b.

All of these component portions of the slat 10 extend longitudinally along the length of the slat and constitute a side-by-side series transversely of the slat, that is to say, across the slat width. The series may be regarded as commencing with either the locking groove 10d at the forward edge of the slat, or .with the locking tongue 10e at the V rearward edge of the slat.

The locking groove member 10d is formed along the underside of the forward longitudinal edge margin of the slat, with the mouth of its groove opening rearwardly so as to receive, in securely interlockingrelationship, the forwardly projecting locking tongue 10a of the next lower'slat. The roofing strip portion 10a and adjoining securement strip portion 10b are both imperforate, and are disposed at an obtuse angle relative to one another. They both extend rearwardly in a continuously substantially fiat expanse, the roofing strip portion being slightly bowed upwardly along its width, as illustrated, to give added strength. The upstanding, apertured wall portion advantageously stands at right angles to the securement strip portion 10b which its adjoins, though the angular relationship may vary to one side or the other of the perpendicular, depending upon the ornamental eifect desired in particular circumstances and upon the degree of'slope of the awning roof in any given instance. The locking tongue member 10e projects forwardly a sufiicicnt distance to protect the apertures 12 of upstanding wall portion 100 against entrance of rain and other precipitation resulting from inclement weather. The extent of its forward projection is preferably such as to completely overhang the securement strip portion 1%, considered along the vertical in any given installation, thereby establishing the main drip-line of the interlocked arrang'ement'somewhat in advance of the fasteners, such as the screws 13, used to secure the individual slats to the supporting framework of the awning. It will be noted that, for rigidity of construction, the screws 13 are disposed within the securement strip portion 10b immediately adjacent its joinder with main roofing strip portion 10a.

As here illustrated, see Fig. 1, the awning is installed directly against the exposed face of a wall 14. The supporting framework comprises a pair of side members 15 in the form of structural steel angles, and upper and lower longitudinal members 16, also in the form of structural steel angles. A pair of supports 17 are respectively disposed between the lower ends of opposite sides of the so formed structural framework and the wall 14. The screws 13 secure the individual slats 10 directly to the side members 15, as illustrated.

A Wide variety of other types of supporting structure may, of course, be adopted without altering the structural essentials of the awning roof formed by the interlocking slats 10.

As is taught by the afore-mentioned Gunter Patent Number- 2,627,634, the lockinggroove member 10d of each slat is formed to terminate sufficiently short of the outer face of upstanding, apertured wall portion 10c to establish an advance, safety drip-line 18 protecting the apertures against creeping of moisture thereinto. The attainment of this feature in a horizontal slat type of awning is one of the advantageousand sought for results of the present invention.

In the particular embodiment illustrated, the upper terminal slat 10-1 has the normalapertured wall 10c and forwardly projecting tongue member 10c replaced by an upstanding but rearwardly canted wall member 19-, serving, in effect, as a protective flashing between the awning and the forward face of the wall. On the other hand, the lower terminal slat 104 has the normal groove member 10d replaced bya downwardly projecting wall member 20, which provides a finish facing along the forward edge face of the awning.

The ventilating and light-admitting apertures 12 are preferably provided at closely spaced intervals along the length of the upstanding wall portion 10c. "It will be noted that, in connectionwith the specially configurated slat described above, a maximum amount of air' and light is admitted through the protective canopy provided by the awning structure of the invention.

While many of the advantages of the present awning construction will be obtained whether .or not apertures are provided, for example, ease and economy of fabrication and installation, attractiveness of appearance, and structural strength and rigidity, the, greatest advantages from the invention are bad when the aperturesare provided to admit air and light.

The slats 10, 10-1, and 104 may be fabricated from any suitable material and in any suitable manner. Nevertheless, it is preferred that they be suitably bent to final configuration from elongate strips of lightweight sheet metal, following appropriate perforation in the providing ofthe series of apertures 12.

Whereas this invention is here illustrated and described with respect to a particular preferred embodiment thereof, it should be realized that various changes may be made without departing from the scope of the claims which here follow.
