' PUSH-BAR Filed July 10, 1950 FIGQZ.

INVENTOR. RICHARD BUBDICK Patented Jan. 15, 1952 UNITED STATES PATENT F F I CE 2 Claims.

This invention relates in general to certain new and useful improvements in door hardware and, more particularly, to a push-bar adapted for mounting upon store doors to facilitate the opening and handling thereof as customers pass in and out.

It is the primary object of the present invention to provide a store-door push-bar of the type stated which is highly attractive in appearance and will serve the dual purpose of presenting an advertising display and at the same time afford a safe, convenient and durable pressure-receiving element against which the user may place a hand in pushing the door open.

It is a further object of the present invention to provide a store door push-bar of the type stated which is conveniently extensible in length so as to fit a wide range of door sizes without any substantial loss in strength.

It is another object of the present invention to provide a store door push-bar which can be easily and quickly installed by any person even without special mechanical skill or dexterity.

With the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts presently described and pointed out in the claims.

In the accompanying drawing:

Figure 1 is a front elevational view of a store door push-bar constructed in accordance with and embodying the present invention;

Figure 2 is a transverse sectional view taken along line 22 of Figure 1;

Figure 3 is a side elevational view of the store door push-bar; and

Figure 4 is a fragmentary sectional view taken along line 4-4 of Figure 1.

Referring now in more detail and by reference characters to the drawings, which illustrate a preferred embodiment of the present invention, A designates a store door push-bar comprising a central element l which is cast or otherwise formed from aluminum or other suitable material and is preferably shaped to represent an advertising symbol, device, or display such as the bottle-top design shown which may be employed, for example, by a soft beverage bottler or brewer. Irrespective of the peripheral contours, however, the element I is wider or thicker at the bottom and narrower or thinner at the top so that the forwardly presented surface 2 is inclined, as best seen in Figure 3.

Formed in and extending horizontally across the back face 3 of the element I are two spaced parallel channel-shaped slots 4 for snugly receiving channel members 5 held therein by screws 6, and extending outwardly therefrom equidistantly on each side. The channel members 5 integrally include a, central web I, having an inwardly pressed corrugation 8 and lateral legs 9 terminating in inwardly bent flanges I0.

Slidably disposed in and extending outwardly from each end of the channel members 5 are companion-shaped extensible bars II formed in a channel-shape similar to the shape of the channel members 5 for snug telescopic fit therein, as best seen in Figure 4. At their outer ends the bars I i are curved rearwardly to provide offset shoulders I2 terminating in clover-shaped attachment pads [3 having apertures I4 for receiving screws It by which the push-bar A is mounted on the stiles It of a store door B, as best seen in Figure 1.

The push-bar A can be packaged compactly by sliding the bars I I inwardly as far as possible and later when it is desired to mount the pushbar A on a store door B the bars I I may be pulled out to Whatever overall length may be required by the width of the door B, and screwed in place with the angular front face 2 inclined so that it faces up toward the customer as he approaches the door B. Thus the wording conveying the advertising message which obviously may be imprinted upon the surface 2 will be easy to read. Furthermore, the inclination of the surface makes the hand of the user rest more comfortably upon the element I. Most important, however, is the fact that the snug telescopic fit between the extensible bars I I and the channel members 5 provides great rigidity when the push-bar A is finally mounted.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the pushbar may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A door push-bar comprisin a central element having an inclined forwardly presented face and spaced parallel slots formed in its rear face, and extensible bars mounted in said slots.

2. A door push-bar comprising a central element having an inclined forwardly presented face and spaced parallel slots formed in its rear face, channel members rigidly mounted in, and extending laterally outwardly on both sides from, the slots, and extensible bars telescopically disposed in and projecting outwardly from each end of each channel member.
