DONALD C VVILL/AMS am/ RICHARD 6. 6/?0WE United States Patent 3,529,798 SIGN ASSEMBLY Donald C. Williams, 4105 Roselawn Ave., Indianapolis, Ind. 46226, and Richard G. Growe, Indianapolis, Ind.; said Growe assignor to said Williams Filed Aug. 30, 1967, Ser. No. 664,559 Int. Cl. G09f 7/18 US. Cl. 248-469 7 Claims ABSTRACT OF THE DISCLOSURE A sign assembly including a group of bars cut from two extrusions, one having a T-shaped cross section with grooved web, and the other having a T-slotted cross section. One T-slotted bar is mounted to a post with lag screws received in registering apertures thereof. One T- shaped bar is bent L-shaped to form a bracket member, with the short leg received in the slot of the T-slotted bar and the long leg extending horizontally therefrom and receiving a sign plate in the web groove. A cross mount consists of two T-slotted bars aflixed together, the first being received on the horizontal leg of the bracket member and the other receiving another T-shaped bar with a second sign plate in the web groove thereof.
BACKGROUND OF THE INVENTION Field of the invention This invention relates generally to display apparatus and more particularly to sign boards and the mounting means therefor.
Description of the prior art Known prior art signs and brackets are many in number and various in form, and examples may be found in US. patents as follows: 2,641,075, June 9, 1953, Saul; 3,158,349, Nov. 24, 1964, Bergstrom; 2,802,291, Aug. 13, 1957, Bach et al.; 3,154,870, Nov. 3, 1964, Hopp et al.; 2,596,582, May 13, 1952, Michel.
The present invention is particularly beneficial in that although it provides a sturdy and durable apparatus for appropriate display of signs, the construction features enabling attainment of this result at a low cost.
SUMMARY In a typical embodiment of the present invention, a bar is provided with a longitudinally extending slot therein of T-shaped cross section receiving the short leg of an L-shaped bracket member having a T-shaped crosssection. The bar is mounted vertically on a post so that the long-leg of the bracket member is disposed horizontally. The web portion of the T has a groove therein receiving a sign board. A second bar, similar to the first is receivable on the long leg of the bracket member and has still a third bar afiixed thereto but at a 90 degree angle with respect thereto, the slot of the third bar extending horizontally and receiving another member of T-shaped cross section with a groove in the web thereof receiving a second sign board. The three bars may be cut from a single aluminum extrusion, and the bracket member and base member for the second sign board may both be cut from a second aluminum extrusion, the bracket member being thereupon bent to the L-shape. Appropriate apertures and fasteners are provided in the bars for securing the various parts together.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of the sign assembly in a typical environment.
3,529,798 Patented Sept. 22, 1970 DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail, FIG. 1 shows a typical embodiment of the sign assembly of this invention used for a street sign unit. In this embodiment a U-iron 11 is used as the stand and is received securely in the ground 12. It has a plurality of apertures 13 spaced at approximately one inch intervals vertically therealong. A bar 14 is provided with apertures 16 therein registering with two of the apertures 13 in the post 11, these apertures receiving lag screws or bolts whereby the bar 14 is aflixed to the post 11. The bar 14 has a longitudinally extending slot 18 therein which is of T-shaped cross section. The.bar also has a pair of longitudinally extending ribs 19 on the backside thereof opposite the slot 18. These ribs together with the slight channel 21 formed therebetween facilitate the mounting of this bar to posts of various surface shapes, including not only the U-iron illustrated but also circular posts. To facilitate installation of the bar to non-apertured posts, flats are provided at 22 and 23 as shown, at the opposite ends of the slot, to receive metal straps both around the bar and around the pole for mounting purposes. The transverse ribs 24 assist in retaining the straps on the bar and the apertures 1'6 can also be used with registering apertures in the straps for this purpose if desired.
A bracket member 26 is made of an aluminum extrusion having a T-shaped cross section, the bracket being bent in the form of an 'L with the short leg 27 and long leg 28 both retaining the characteristic T-shaped cross section. In the web of the extrusion there is provided a groove 29 extending throughout the length thereof to receive a sign board or plate 31, which may also be aluminum or some other suitable material. The sign board is secured to the bracket by lanced or staked construction as at 32 wherein the web and sign plate are secured together at one or both sides of the groove 29 in both the horizontally and vertically extending legs of the bracket. The vertically extending leg is then received in the slot 18 of the mounting bar 14 and, if desired, can be allowed to rest therein with the flange 33 of the bracket member resting upon the upper marginal edge 34 defining the upper end of the slot 18 in the bar 14. Although the bracket 26 is shown as a hanger for the sign and inserted in the upper end of the slot 18, it can also be inserted upwardly into slot 18 and, in that event, can be secured thereto by a set screw 36 threadedly received in the bar 14 and engaging the short leg 27 of the bracket member. The set screw can also be used, of course, when the bracket member is inserted from the top.
To mount the second sign board 37, a cross consisting of two bars 38 and 39 is provided from the same aluminum extrusion as the bar 14. These two are welded together with their channel sides facing each other, the weld points being at the four points of contact between the ribs 19 of each and the corresponding ribs of the other. The lower component 39 of this cross is received on the horizontal leg 28 of the bracket member and is secured thereto by the set screw 41. A member 42 cut from the same extrusion as the bracket member is received in the slot of the bar 38 and atfixed thereto by the set screw 43. Member 42 already has the groove 44 therein receiving a lower marginal portion of the sign plate 37 which is affixed thereto by the lancing or staking at 46, for example.
So it is that the complete sign assembly is constructed of comparatively few parts at nominal expense, and yet serves as a sturdy and durable unit. Because of the use of extrusions as described, it is a simple matter to make the various members any length desired to accommodate signs of different sizes. Moreover, if it is known that the bar 14 will not need to be mounted by straps to any posts, the transverse slotting to provide the flats 22 and 23 at the ends of the slot 18 can be omitted so that this member also will be virtually identical in this respect to the members 38 and 39. In fact, there are instances Where the members 14, 38, and 39 can be identical as are members 26 and 42, except for the bend in member 26 and a notch in the web at 47 to facilitate bending. This notch, in the straight extrusion, can typically be a notch of 90 degree included angle and a width at the flange of approximately one-eighth inch, for example. The dimensions will vary of course, depending upon the size of stock used.
While the invention has been disclosed and described in some detail in the drawings and foregoing description, they are to be considered as illustrative and not restrictive in character, as other modification may readily suggest themselves to-persons skilled in this art and Within the broad scope of the invention, reference being made to the appended claims.
