ADJUSTABLE AWNING ARM.

Application filed October 7. 1926. Serial No. 189,959.

This invention relates to side arms or supports for awnings of the kind adapted to fold against a vertical surface, such as a wall or store front, when not in use, while the awning fabric is wound upon a roller through the instrumentality, generally, of winding devices.

Arms or supports for awnings of. this character have, heretofore, had to be made to measure for each particular installation.

The principal object of the present invention is the provision of an awning supporting arm which is capable of ad ustment to meet the requirements of practically any 1 installation, although the component elements thereof conform to standard specifications in the interest of quantity production. Accordingly, fittings are provided as connecting means adapted to be associated with certain ofthe elements of the supporting arm whereby the relation of parts may be varied as required dependent upon the conditions met with.

Awnings for store fronts, for instance,

are required under municipal ordinance, to have a certain clearance off the sidewalks. At the same time all .store fronts are not uniform, presenting a different location, n almost every instance, upon which to mount the supporting arms for the awning. While the elevation of the mounting or connection for the supporting arm on the store front may vary, and indeed be at times very much above the prescribed awning clearance, 1t

is imperative that the front or forward edge of the awning, and hence the outer end of the awning supporting arm, be maintained as low as permissible inorder that the shade may extend as far as possible towards the show window.

A further object of the invention is, therefore, the provision of an awning supporting arm capable of attachment, at any helght, 'within limits, above, say, the street level, but adjustable so that the outer end may be maintained at the permissible clearance. According to the invention, the supporting arm includes a compound lever, whereof the effective lengths of the lever-arms are ad- 'justable in steps by a connection therebetween, .while one of the lever arms is carried by a connecting element or bracket on the wall or store front which is'also adjustable to afford still further but smaller differences in the elevation of the outer end between each two adjustments in the effective lengths of the lever arms. More particularly, where the awning supporting arm includes crossed bars, as when it assumes the form of lazy tongs, the finer adjustment or, as it may be called, the vernier adjustment is effected by a connection of one bar with the wall or store front which permits varying the spacing of the inner ends of the said crossed bars.

The invention also seeks to provide an adjustable awning supporting arm which is capable of being folded against the wall or store front in a compact manner. 'To this end the adjustment of the effective lengths of the arms of the compound lever included in the awning support is so made as to retain the same or a predetermined ratio between the component parts.

These and other objects of the invention and the means for their attainment will be more apparent from the following detailed description of a preferred embodiment of the invention, taken in connection with the accompanying drawings, in which:

Fig. 1 is a view in side elevation showing one of the awning supporting arms in operative position on a wall or store front;

Fig. 2 is a view in perspective of the adjustable connection between twoof the arms of the awning support.

Fig. 3. is a view, in front elevation, of what may be called the vernier hinge by which the spacing of the connections of the crossed arm of the support may be varied.

In Fig. 1 only a single awning support in illustrated but it is to be understood that two or more are adapted to be used in every instance. The front wall of a building or show window is indicated by the vertical line 4.- and supported from the wall 4 at a suitable point above the show window, say, is a roller 5, about which the awning 6 is wound. At an available point below the roller 5 there are disposed, upon the wall 4, two lugs or brackets 7 and 8.

From the upper bracket 7, or hinge as it may be called, there extends what is in effeet a compound lever composed of the short arm 9 and a longer arm 10 to which a lever arm 11 extending from lug 8 is pivoted between its ends as at 12. At the outer end of the bar 11 there is pivoted a downwardly will rest.

extending arm 13 and both the arms 10 and 13 are pivoted at their outer ends in spaced relation to the inner end of an outwardly extending arm 14 to the outer end of which the-outer edge of the awning 6 is secured.

The bars 10 and 13 are preferably twin channels, as seen in Fig. 2, between which the arms 9, 11 and 14 extend, and the ends of the arms 10 are of such length as to abut against the adjacent edge of the arm 13 and form a bearing against which the arm That end 14' of the arm 14 to which the arm 10 is pivoted curves upwardly slightly as shown in the drawings.

It will be obvious that the relative position of the outer edge 16 of'the awning with respect to the brackets will depend upon the length of the compound lever 9-10 and hence the general inclination of the arm. To vary this inclination to meet specific requirements of a particular installation, the bar lO-is ivoted as at 17 upon a slide 18 which is slldable along the bar 9 and may be secured in present position by the set screws 19, determining thereby the efl'ective length of the bar 9. The effective length of the bar 10 is also adjustable. As shown, the bar 10 is provided with a plurality of, say six, holes 20 in any one of which the pivot or pin 17 may be placed.

In Fig. 1 in full lines, the pin 17 is shown in the inside or sixth hole and the position assumed by the support and hence the awning is illustrated.

In one physical embodiment, an adjustment of the pin 17 from one hole to the next, the slide being relatively stationary, will result in a drop of six inches at th outer edge 16.

Occasion may arise when a drop of less than, say six inches, is desirable in the outer edge 16. Provision is therefore made for a still finer adjustment by what is called the vernier hinge 7. It will be observed that hinge 7 is provided with an elongated slot 21 so that the pivot pin '22 may move toward or away from the bracket 8 and thus vary the spacing of the two pivots. To position the pivot 22 at a predetermined point in the slot 21 one face of the bracket iscorrugated as at 23 and 'the under face of the head 24 of the pin or bolt 22 is notched as at 25. It is thus only necessary to move the pin 22 to the desired position on the bracket 7 and take up on the nut 26 until the respective corrugations engage whereby the pin is retained in position.

In dotted lines, in Fig. 1, there is indicated, schematically, semi-open position of the awning.

After the proper adjustment has been made the surplus ends of rods 9 and 10 may be cut off, if desired.

It will thus be seen that an awning support has been provided which is adjustable to fit a particular situation although the component elementsmay be constructed as standard stock equipment.

Various modifications may be made in the character of the connections whereby the adjustment is efi'ected and no limitation is intended by the phraseology of the foregoing description or illustrations in the accompanying drawings except as indicated by the appended claims.
