Dec, 17, 1940. E. R. ERICKSON PUSH BAR Filed Dec. 11, 1959 ATTORNEYS Patented Dec. 17, 1940 PATENT OFFICE i PUSH BAR Ernest R.. Erickson, Des Moines, Iowa, assignor to C. E. Erickson Company, Incorporated, Des Moines, Iowa, a corporation of Iowa Application December 11, 1939, Serial No. 308,729

5 Claims.

My invention has reference to that class of devices used by attachment to the stiles of a door to form a horizontal cross member by which the door can conveniently be pushed open.

An object of my invention is to provide a push bar of the type above referred to which can be readily adapted to doors of various widths.

Another object is to provide a construction in which the principal structural elements are parfticularly adapted for carrying an advertising or sales promotion message, or other printed or decorative matter.

In View of the last mentioned object, a further object is to provide a construction in which the principal structural elements above mentioned can be readily interchanged.

Another object is to provide a barfconstructed with end extension elements in which the assembly shall be rm and rigid and in which the parts can be maintained in assembled relation by a minimum number of bolts.

With these and other objects in view, my in' vention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing. Although rthe invention is susceptible of a variety of embodiments, O it is necessary to fully describe and illustrate more than one in order to give a full understanding of the invention both from its structural and functional standpoinfts. `Accordingly,

I have illustrated a preferred and desirable embodiment of the invention in the accompanying drawing, in which:

Figure 1 is a perspective view of a door with a push bar embodying my invention represented as attached to the door.

n Figure 2 is a top plan View of my device, a part of the figure being in horizontal section.

Figure 3 is a view, partly in vertical section, taken on the line 3-3 of Figure 2.

Figure 4 is an enlarged vertical sectional view taken on the line 4 4 of Figure 3; and

Figure 5 is an enlarged vertical sectional view taken on the line 5-5 of Figure 3.

In the accompanying drawing I have used the reference numeral I to indicate generally a door of the type with which my device is commonly used. The door I0 has vertical stiles I2 and I4 to which my push bar is attached by screws I6. Such an installation is commonly made on the doors of grocery stores and mar- 55 kets, both to provide attractive ornamentation therefor and to protect the glass from fingermarks, etc.

It has become a practice among bakeries and other wholesale purveyors of foodstuffs to furnish door pushes of this type to grocery stores, and advertising or sales promotion message with relation to certain food products being displayed on the bar or attached thereto. Obviously, such a device must incorporate some arrangement whereby it can be adapted to doors of various widths.

Furthermore, in view of the fact that the back side of the push bar can be viewed throughsthe glass in the door, or through the screen wire, when fthe bar is used on a screen door, it is desirable to place a message or decoration on that side of the bar as Well as on the more exposed side. In case the two messages are not the same, it may be desirable to locate one of them on the back or front of the bar according to 20 whether the bar will face fthe inside of the store or toward the outside. For example, the message Thanksl Call Againl should be faced so that it is read by a customer going out through the door upon leaving the store. If the push bar is located on the inside of a screen door, then the message above quoted should be located on the side of the bar away from the screen. On the other hand, if the bar is to be aiiixed to the outside of the glass door, then 3 the quoted message should be on the side of the bar next to fthe glass. Therefore it is desirable to have a construction wherein the desired message can be conveniently mounted on either side of the bar, or whereby a desired combination of messages can be assembled to make up a bar.

In the detailed views showing my push bar, the numerals I8 and 20 indicate generally a pair of plates, the shape of which is best shown in the cross sectional view'of Figure 5. As there 40 shown, plate 20 comprises a iiat front portion 22, and beveled edge portions 24, which constitute a flange giving strength Vand rigidity to the plate. The edges of the beveled portions 24 terminate in inturned iianges 26. The plates I8 45 and 20 are identical as to their cross sectional shape, and, as shown in Figure 5, they are located back to back, fthe iianges 26 being adjacent. This adjacent relationship is maintained by caps 28 and 30 which engage the ends 50 of the plates I8 and 20 and hold them together.

The assembly thus far described constitutes the central portion of my push bar. It is supported on stiles I2 and I4 by the extension members indicated generally as 32. 'I'he latter have 55 a foot portion 34 with perforations 36 to receive the screws I6. Extending at an angle from the foot portion 34, is a portion 38 whereby the bar is spaced away from the door. The portion 38 connects with a longitudinally extending portion 40 which is formed in cross section as shown in Figure 4. The shape therein indicated gives greater strength and rigidity to the member than it would have if it were a ilat plate. The portion 48 of the extension members 32 passes through a slot 42 in the caps 28 and 3. At the inner end, the portion 40 is provided at top and bottom edges with hooked ends, the conformation of which is shown in Figures 2, 3 and 5. It will be seen in Figure 5 that along the greater portion of the length of the pant` 40 of the extension members 32, the outer edges 44 lie along the inside facev of the flanges 25 on the plate I8. At the inner end of the part 40 however, the edge 44 is bent as shown at 46 in Figure 2, and is provided with a notch 48` whereby it engages the inturned flanges' 28 on the plates I3L and 2D. The engagement/of` the notches i8 with the flanges 26 accomplishes two` results. In the rst place, it'lachieves great rigidity of the extension members 32 with`re spect to the central assembly" comprising plates I8 and2ll and the caps 28' and 39. The inner end of the extension members 32`isguidedbythe coaction of the ilanges 28i with the notches (18, and the outer end by the passage through the slots 42 in the caps 28% and 3W. Ak secondi result is that spreading of the mid pontions` off the plates I8 and 2liv is prevented, because the plates are iirmly held together intermediate their ends by the fact that the notches 48' embrace the iianges 26 `on both plates I8 and 2U.

Adjustment of the push bar to t' doors of various widths is accomplished by slidingA the `extension members 32` throughA the caps` 28 and 30, and the desired extension is maintained by passage of the bolts 50 through the caps 28 and 30, plates I8 and 20 and suitable holes 52 in the parts48 of the extension members3'2`.

The flat portions 22 of? the plates I-'8- and 20 are well adaptedfor carrying a sales `mes-` sage; which may be applied by lithographing, silk screen process or i'nany other suitable manner. In actual production, in order to` make the costs as low as possible, it is desirable tomake up these separate plates in large quantities with various printed matter thereon. A pair ofplates having the desired combination. of. messages `can then; be conveniently assembled' withl thev caps 28 and` 3B andthe extension members. 32.: In-

asmuch as the plates I8 and 20X are' identical in.

shape, they may be reversed orl interchanged` in position so that a desired` sales .message can' be made to face either inwardly oroutward'ly withy respect toi the mounting surface; The complete assembly is held in neat. and rigid form" by only two bolts. A4 deviceA is thusv provided; the parts of which can be economically made up by large production methods, and` which can be readily adapted to ll the varying requirements of different applications.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modiiied forms of structure or use of mechanical equivalents, which may be reasonably included within their SCOpe.
