This invention relates to hanging devices for trays, placques, pictures and similar objects plary use of such a hangeris in connection with lithographed or decorated metal trays.

By modern lithographic methods, artistic, multicolored landscapes, flowers, reproductions of classical paintings, etc. may be printed on a metal blank from which a tray is made, and thereby provide finished trays which are useful notonly as refreshment handling trays but are also artistic enough to hang on walls in lieu of framed prints, paintings or other works of art. Such metal trays are made by drawing a flat blank and forming a central panel surrounded by an imperforate, transversely bent border terminating at its outer periphery in a curled edge into which the flange of a metal strip hanger may be projected or locked. The back surface of the panel of such a metal tray presents a smooth imperforate surface which makes it difficult to attach present hanging devices without the hanger showing when the tray is in display position.

An object of the invention, therefore, is the provision of a tray hanging device, economically made from a strip of resilient material such as sheet metal strip, which is of a shape and has terminal flanges which cooperate with the terminal portions on thetray to secure the two together without any portion of the hanger showing when the tray is in display position.

Another object is the provision of a tray hanging device made from a resilient strip of material having a central portion. which is resiliently curved before application and, which is straightened out upon application to lie snugly against the body surface of a tray panel.

4 Claims. (01. 248---3(l) Yet another object is the provision of a tray hangi g device of the type described that is adjustable as to its length so as to fit trays ofvarious dimensions.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which,

taken in connection with the accompanying drawings, disclose a preferred embodiment thereof.

Referring to the drawings:

Figure 1 is a perspective view of a tray hanger embodying the instant invention;

Fig. 2 shows an edge view of the hanger of the instant invention applied to the back of a metal tray shown in cross section;

Fig. 3 shows a perspective view of the hanger applied to a metal tray shown in broken lines in rear elevation;

Fig. 4 is a perspective view of a modified form of the invention; and

Fig. 5 shows a sectional view of the modified form of hanger shown in Fig. 4 applied to the back of a metal tray.

A representative tray A (Figs. 2, 3 and 5) which can be suspended by or used with the hanger comprises a flat countersunk central panel ll, entirely surrounded by integral transversely bent side or countersink walls l2, which may be gracefully curved either as shown, or straight, as preferred. The side Walls 12 at their outer or marginal edges merge into a peripheral rearward projection or open curl l3, which may extend around the entire perimeter of the tray. A hanger flange receiving channel it is thus provided between the back of a side wall I2 and the terminal edge is of the peripheral curl l3 As a preferred or exemplary embodiment of the invention, the drawings (Figs. 1, 2 and 3) show a hanger B, made from a flat, resilient metal strip, such as a light gauge spring steel that is substantially rectangular in cross section, although other resilient materials, such as plastics and plastic impregnated fibers may also serve the purpose. The tray hanger comprises an elongated central body portion 16 which when the hanger is fully applied lies fiush against the back or bottom surface of the tray panel. This central portion is is initially bowed inwardly or arched slightly to provide for extension when fully straightened against the back of a tray panel II and also to exert a rearward spring tension or pressure against the ends of the hanger, as will be described.

Near the bottom end, as viewed in Fig. 1, the body portion It, merges into an inwardly bent angular or offset bridging section I8 at a line of bend IT. This offset section [8 is bent reversely near its terminal edge to provide an outwardly projecting tray engaging flange or hook portion I9. The angle between the body portion [6 and the offset section I8 is obtuse or substantially 3 greater than 90 degrees and remains so when assembled on a tray.

The top of the hanger is bent at 20 to form a top inwardly bent angular or bridging or ofiset section 2|, which is outwardly or reversely bent near its terminal edge to provide a top tray engaging flange or hook portion 22. The angle of bend at 2|] is substantially 90- degrees or only slightly greater when assembled with the tray. Adjacent the top bend 20 is a perforation 23 in the body portion Hi to accommodate a hook, the head of a nail or other suspending means.

To assemble the tray and hanger, the bottom flange i9 of the hanger is inserted into the flange receiving channel id of the tray. The bottom bend ll of the hanger coincides closely with the juncture 24 (Fig. 2) of the panel II and side walls i2 of the tray. The bottom offset section it of the hanger extends along and is spaced from the back of the side walls 12 of the tray and spans the distance between the juncture 24 and the terminal edge I of the curl l3. The bottom flange |9 of the hanger projects into channel l4 and abuts against the terminal edge l5 of the peripheral curl 53. After the bottom of the hanger is in the position described, the top offset section 2| is forced downwardly slightly and the top flange 22 is snapped into the flange receiving channel It of the tray at a point diametrically opposite the bottom flange it of the hanger. The top flange of the hanger projects into channel It and abuts against the terminal edge of the peripheral curl I3 of the tray. The angle or line of bend 23 of the top offset section 2| of the hanger is located above the juncture 2 1 between the tray panel I and the side wall i2, to provide an open space or area 25 for the reception of the protruding head of a hook or nail that may be projected through perforation 23.

'In this assembled relation, the angle between the bottom offset section I3 and the body portion l6 of the hanger remains obtuse. The angle between the top offset section 2| and the body portion It, however, is about 90 degrees or only slightly greater.

The normal bow or arch of the body portion i8 is thus manually flexed so that the hanger lies substantially straight and flush against the back of the panel, thereby exerting spring tension to urge the bottom and top ofiset sections I8 and 2| r and their respective flanges is and 22 into firm abutting engagement against the terminal edges l5 of the peripheral curl l3.

A modified form C of the invention (Figs. 4 and 5) comprises two similar or like strips or parts 3| which are adjustably joined as to length by a slot and tongue connection, to form a hanger that is adaptable for use on various sized trays. Inasmuch as each part 3| of the hanger has a similar construction, only one such part will be described.

Each part or strip 3| has a reversely bent flange or hook 32 at one end. Adjacent each flange 32 is an angular or bridging or oifset section 33 which merges with an elongated, arched or bowed central portion 3-4 at a line of bend 35. The arched or bowed portion 34 has a plurality of slots 33 of approximately uniform size punched along the central longitudinal axis of the hanger. At the end opposite to flange 32, each part or strip 3| terminates in a stepped tongue 31, so

4 approximately the thickness of the material from which the hanger is made. By passing the tongue of one part through a slot of a second similar part and interlocking them, the length of a hanger can be adjusted to fit a number of differently dimensioned trays.

A tab or lug 39'containing a nail or hook perforation 43 is struck from each angular or offset section 33 and bent backwardly until it is substantially in a plane with the arched or bowed portion 34. A space 4| between the tab and angular section 33 is provided for the protruding head of a nail or hook or other suspending means for the assembled tray and hanger.

The angle between body portion 33 and the offset section 33 is obtuse or substantially greater than degrees, and is substantially the same for each part or strip 3|.

In assembling a tray with the adjustable hanger, the parts are adjusted to proper length and interlocked by passing a tongue 31 of one part 3| through a slot 36 of a complementary strip 3| (Fig. 5). One flange 32 of the adjusted hanger is then placed in the flange receiving channel I4 and the opposite flange is snapped under the terminal edge I!) of the curl |3 at a diametrically opposite part of the tray. The bend 35 in each part 3| of the hanger substantially coincides with a respective juncture 24 between a tray panel II and a side wall I2 thereof, and each angular or ofiset section 33 of the hanger forms an obtuse angle or an angle substantially greater than 90 degrees with its main body portion. The hanger lies substantially flush against the back of panel II, and, as in the previously mentioned preferred form of the invention, the bow or arch of the main body portion providing for slight hanger elongation, tending to urge the bridging section and their flanges rearwardly slightly so that the flanges 32 of the hanger abut against the terminal edge l5 of the curl l3 of the tray. In the adjustable structure there is no need to distinguish between a top and bottom end for the hanger, since the parts are so similar that they can be used interchangeably as either top or bottom.

Although a slot and tongue connection is shown to adjust the length of and interlock the two parts of the adjustable hanger, it is to be understood that any other means of adjusting the length may be used, such, for example, as a slot and screw, a sleeve that slides over the periphery of the parts, or any other well known means of accomplishing such a result.

For economy in manufacture, it is preferable to have each part 3| of similar or identical construction. It is also possible to make an adjustable tray hanger in which the upper part has a structure similar to the top half of the hanger of Fig. 1 and the bottom the same as that shown in Fig. 4. r Similarly, the one-piece hanger in Fig. 1 can readily be modified by having each angle of bend substantially equal, and striking a tab or lug from the top offset part, like that shown at 39 in Figs. 4 and 5.

After either the one-piece hanger or the adjustable multi-part hanger is assembled with a tray, the hanger may be manually shifted or slid along the flange receiving channel into a tray balancing position (Fig. 3) at which time the assembly is ready for suspending from a hook or nail. The construction and assembly thus described has the advantage of providing an effective hanger device which is entirely hidden from view when the tray is hung from a support in ultimate display position.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction, and arrangement of the parts, without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the construction hereinbefore described being merely a preferred embodiment thereof.
