4/54? IAaw/fimair United States Patent O 3,510,975 SIGN ASSEMBLY FOR MOTOR VEHICLES William J. Lowrnaster, Royal Oak, Mich., assignor to The Mathews Company, a corporation of Michigan Filed June 16, 1967, Ser. No. 646,538 Int. Cl. G091? 7/100 U.S. Cl. 40129 1 Claim ABSTRACT OF THE DISCLOSURE A motor vehicle embodying a sign assembly carried on opposite sides, front and rear of the vehicle for indicating the class of goods carried by the vehicle. Each sign assembly is comprised of a mounting portion in which a plurality of stacked cards bearing dilferent legends are supported. A restraining means holds the cards within the stack and permits selective repositioning of the cards for changing the exposed legend.
BACKGROUND OF THE INVENTION This invention relates to a sign assembly for motor vehicles or the like and more particularly to a sign assembly that facilitates rapid interchange of the indicating material of the sign assembly.
Motor vehicles such as highway trucks normally carry a wide variety of classes of cargo. Certain safety benefits may inure from the provision of readily visible indicators on the exterior of the vehicle for indicating the class of goods carried by it. The variety of different goods carried by such vehicles, however, makes it necessary that the indicating legend on such signs may be readily changed. In addition to otfering convenient interchange, such sign assemblies preferably should include provision for permitting interchange of the legend without resorting to an extraneous source. That is, all of the necessary legend should form a part of the sign assembly and be carried directly by the vehicle.
It is, therefore, a principal object of this invention to provide an improved sign assembly for a motor vehicle.
It is another object of this invention to provide a motor vehicle sign assembly that facilitates changing of the indicating legend of the sign assembly.
It is a further object of this invention to provide a self contained sign assembly adapted to provide a number of different types of indications.
SUMMARY OF THE INVENTION A sign assembly embodying this invention is particularly adapted for use with motor vehicles for indicating the class of goods carried by the vehicle. The sign assembly comprises a mounting portion that is adapted to be afllxed to the exterior of the motor vehicle. Flange means extend outwardly from at least two opposite sides of the mounting portion for supporting engaging opposite sides of a plurality of stacked cards bearing indicating legend on at least one face of each of the cards. Tab means extend from the flange means toward each other and are adapted to overlie the outermost card in the stack for retaining the stack of cards relative to the mounting portion. The tab means terminate short of the legend on the outermost card for facilitating the reading of the legend thereupon. At least one side of the mounting portion is free of flanges for facilitating sliding of the cards from beneath the tab means for permitting interchange of the outermost card of the stack. Releasable restraining means are carried by the one side of the mounting portion for engaging the stack of cards and for coacting with the flange means and the tab means to restrain the stack of cards relative to the mounting portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A motor vehicle embodying this invention is identified generally by the reference numeral 11 in FIG. 1. The motor vehicle may be of any of the known freight transporting types and is depicted as a tractor-trailer combination consisting of a tractor 12 and trailer 13. Indicating sign assemblies embodying this invention are identified generally by the reference numeral 14. As will become more apparent as this description proceeds, indicating sign assemblies 14 preferably are mounted on opposite sides, front and rear of the trailer 13. mounting portion, indicated generally by the reference Each of the sign assemblies 14 is comprised of a numeral 15, which may be formed from sheet metal or any other similar material which may be plated, coated, painted or otherwise protected from corrosion. The mounting portion 15 consists of a generally rectangular rear face 16 in which countersunk openings 17 are formed to pass flat headed bolts or screws for facilitating attachment of the sign assembly 14 to the associated vehicle. Outwardly extending flanges 18 and 19 are formed integrally with the top and bottom edges of the rear face 16. The flanges 18 and 19 extend substantially the full length of the rear face 16. The outer extremity of the flanges 18 and 19 are integrally connected to inwardly extending tabs 21 and 22, respectively. At one side the tabs 21 and 22 are cut off at an angle, as at 23 and 24, and the opposite ends of the tabs 21 and 22 are rounded, as at 25 and 26. An outwardly extending flange 27 is formed integrally with one end of the rear face 16, the end adjacent the cut off portions 23 and 24 of the tabs 21 and 22. The flange 27 is substantially coextensive with the height of the face 16 and terminates at its outer end in an inwardly extending tab 28. The tab 28 is cut off, as at 29 and 31.
It should be readily apparent that the mounting portion 14 may be conveniently formed with the flanges 18, 19 and 27 extending perpendicular to the face 16 and the tabs 21, 22 and 28 extending parallel to the face 16. The cut olf edges 23, 24 and 29, 31 of the tabs 21, 22 and 28, respectively, permits folding without interference at the adjacent edges.
A plurality of generally rectangular cards, indicated by the reference numerals 32, 33, 34, 35, 36, 37 and 38, are adapted to be supported within the mounting portion 15. Each of the cards 32 through 38 may be formed with a different legend on at least one of its faces, and the number of such cards necessary may be reduced by forming legend on both faces of the cards. The cards may be formed from sheet metal, composition boar-d, plastic or the like so as to be weather resistant. The legend on each face of each card represents a different class of goods which may be carried within the vehicle 11.
The distance between the flanges 18 and 19 is preferably about equal to the height of the cards 32 through 38 so as to snugly engage the stack of cards within the mounting portion 15. in a like manner, the flange 27 will engage one edge of the cards 32 through 38 so that the cards 32 through 38 are supportingly engaged along three of their sides by the respective flanges 18, 19 and 27. The tabs 21, 22 and 28 overlie the uppermost card 38 of the stack and assist in preventing the cards from falling outwardly from within the mounting portion 15. The tabs 21, 22 and 28, however, terminate short of the legend on the cards so that the mounting portion 15 presents a substantially open outer face through which the legend may be viewed.
The mounting portion face 16 is somewhat longer than the length of the cards 32 through 38 and the edge pposite to the flange 27 and tab 28 is generally open to facilitate sliding of the respective cards from within the mounting portion '15 to permit changing of the indicia presented by the outermost card on the stack. A releasable retainer, indicated generally by the reference numeral 39, is provided to engage the cards 32 through 38 at this end of the mounting portion to prevent accidental displacement of the cards 32 through 38. The retainer 39 is mounted in an inwardly recessed portion 41 of the rear face 16 of the mounting portion 15. The retainer 39 comprises a base portion 42 having a bifurcated end 43 that defines spaced arcuate portions 44. A flange 45 of a retaining member 46 extends through and is journaled within the arcuate portions 45. The retaining member 46 is generally of a Z-shape and is adapted to engage the cards in the position shown in the drawings. The member 46 may be rotated, however, through 180 through yielding of the bifurcated arm 43 to release the cards 32 through 38 for changing of the outermost card.
It should be readily apparent that a relatively simple sign assembly has been provided that permits rapid interchange of the legend and which is substantially self-contained. If additional information is to be indicated, cards may be added since the flanges 18, 19 and 27 are somewhat longer than the height of the stack of cards initially employed. In addition, the outermost card on the stack protects the remaining cards from dirt and other foreign matter and may be conveniently washed along the remainder of the vehicle.
While it will be apparent that the preferred embodiment of the invention disclosed is well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope or fair meaning of the subjoined claim.
