MOVABLE AWNING 3mm .6i/0726s Patented May 3 1, 1949 UNITED STATES PATENT OFFICEv n MOVABLE AWNING Henry G. Jones, Austin, Tex.

Application January 6, 1947, Serial No. 720,430

1 Claim. 1

This invention relates to metal awnings, and more particularly to a metal awning having movable louvres.

It is an object of this invention to provide an awning of the kind to be more specifically described hereinafter, having an improved operator for moving the louvres from a closed to an open position, or any intermediate position desired.

Another object of this invention is to provide an improved operator for metal awnings of this kind, which is .very eicient by virtue of the simplicity of its construction, having but a single moving part for engaging with a serrated plate or rack xed to the louvre operating bar.

A further object of this invention is to provide an improved operating means for a metal awning or the like, which will be extremely simple and easy to manufacture and assemble, and which by this simplicity, will require a very minimum amount of maintenance, thus presenting the most desirable characteristics required by manufacturers and purchasers at the same time.

With the above and other objects in view, my invention consists in the arrangement, combination and details of constluction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.

In the drawings,

Figure 1 is a vertical section through an awning constructed according to an embodiment of l this invention,

Figure 2 is a fragmentary section taken on the line 2-2 of Figure 1,

Figure 3 is a bottom plan View of the connecting bars removed from the awning, partly broken away and partly in section,

Figure 4 is a fragmentary section taken on the line 4 4 of Figure 1,

Figure 5 is a section taken on the line 5-5 of Figure 4,

Figure 6 is a fragmentary detail side elevation of the apertured plate of one of the connecting bars,

Figure .7 is a plan view of the crank detached from the operating mechanism.

Referring to the drawings, the numeral II) designates generally a metal awning having movable louvres o erated by an operator, constructed according to an embodiment of this invention. The awning I0 is formed of a horizontal U-shaped frame at the lower end thereof. The side members I2 of the frame |I are formed U-shaped in section, and the bight or outer member I4 is formed of an L-shaped section.

A vertical frame I5, U-shaped in overall dimensions is xed to the inner or free end of the horizontal frame H. The frame I5 is formed of L-shaped side arms IG, and a bight or upper section is substantially U-shaped or channeled in section. As the free ends of the vertical frame I5 are xed to the `free ends of the horizontal frame Ii, the entire inner end of the awning I0 is opened. The vertical frame I5 is adapted to be fixed to a wall i8 about a window opening I9. A pair of downwardly and outwardly inclined side members 2t are iixed between the divergent ends of the frames and I5.

The side members 2i! are U-shaped in transverse section as shown in Figure 2 of the drawings. Louvres 2| are pivotally supported between the opposed side members 28 by a pin 22 through the flanged portion 24 at each end of the louvres 2|, and through the inner arm 25 of the U-shaped side members 20. The louvres 2| are so shaped that the lowermost edge of each louvre is adapted to overlie the uppermost edge of the next lower louvre to exclude rain or moisture from entering between the louvres when they are in the closed position.

The louvres 2| are xed together for unitary movement so that the movement of one, either opened or closed, will effect a similar movement of all the other louvres 2|. For effecting this unitary movement of the louvres 2 I, a connecting bar 2S is pivotally attached to each end of the louvres 2| by a pin 21 at the lower end of the V-shaped flange 2li at each end of the louvres. The connecting bars 2S are of an inverted L-shape in section for added strength and are disposed 1 below the side members 2|) of the awning I0. A

transverse L-shaped connecting bar 28 is xed between the opposite connecting bars 26 to provide a rigid frame for moving both ends of all the louvres at one time.

The louvres 2| may be operated .by a person from within the house or on the opposite side of the window opening I9. For rocking the louvres 2| a simple and eicient operator is provided. An apertured plate 3|) is fixed to or formed on one of the connecting bars 26 intermediate the length thereof. The plate 30 extends below the lower edge of the connecting bar 26 and is formed with a series of elongated rectangular apertures 3| perpendicular to the length of the connecting bar 25.

The series of openings 3| form a rack for operating the louvres from open or closed position. An L-shaped bracket as 32 is xed to one of the side members 20 on the same side as the plate 30 for supporting a shaft 33 at its upper end, and

a bracket 34 is fixed to the inside edge of one of the arms I6 of the vertical frame l5 for rotatably supporting the shaft 33 at its lower end.

Bearing plates 35 are fixed on the shaft 33, one below the bracket 32 and one above the bracket 34 for holding the shaft 33 against sliding movement in the bracket. A spur gear 3B is xed on the upper end of the shaft 33 and the teeth of the gear 36 are adapted to engage in the openings 3| of the rack 30. Rotation of the shaft 33 will then eiect longitudinal movement of the connecting bar 26 which in turn effects pivotal movement of the louvres 2| between the side members 20, for opening or closing the louvres.

The lower end of the shaft 33 is adapted to extend inwardly beyond the bracket 34 and be ter'- minated outwardly of the outer edge of theV window opening I9. The lower end of the shaft 33 is formed with a longitudinally extending rectangular opening 3l for the vengagement of a crank 38:- for rotating the shaft 33. The crank 38 is formed of an elongated rod having a handle 39' atY one end thereof, and a rectangular outer end Si which is adapted to engage in the opening 3l so' that the shaft 33 may be rotated thereby. The crank 381 when not in use may be removed from the shaft 33v and placed in a convenient location where it may be easily reached for changing the position of the louvres.

Fixed louvres 4| are disposed horizontally across the sides of the awning lll. The louvres 4| are fixed in frames 42 which are removably secured to the frames and I5 and engage between the arms of the inclined side members 2D'.k

The lowermost edges of each of the fixed louvres 4| is adapted to overlie the upper edge of the next lower louvre in the same manner as the pivoted louvres 2| in their partially closed position. The

construction and installation of the side frames 5 42 is preferably the same as that shown and described in my copending application for a xed awning.

What I claim is:

In a metal awning having transverse pivoted louvers, an operator forI rocking said louvers about the pivots thereof, said operator including a connecting bar, means rockably connecting said bar to each of said louvers, a depending plate on said bar formed with a plurality of adjacent elongated openings disposed at a right angle relati've to the length thereof, a toothed gear rotatably carried by said awning, the teeth of said gear engageable in said openings and sldable along the length thereof for rocking said louvers upon rotation of said gear.
