Int. Cl. G09f 7/00 U.S. Cl. 40--129 17 Claims ABSTRACT F THE DISCLOSURE In the copending application of William J. Lowmaster entitled Vehicular Sign, Ser. No. 690,236, led Dec. 13, 1967, and assigned to the assignee of this application, there is disclosed a vehicular sign for indicating the character of goods carried by the vehicle wherein a pack of individual sign cards are stored in a sign carrier mounted on a Supporting member. Signs are changed by moving the sign carrier to a sign changing position relative to the supporting member and then rearranging the individual cards to place the desired sign on top of the pack. When the sign carrier is pushed back into the supporting member, the sign cards are held in place by the sign carrier and the supporting member. Although this sign is useful for most applications, it is desirable to have different sign constructions available to meet the demand and choice of prospective purchasers. Also it is possible that a sign card may be lost accidentally or stolen.

Therefore, the object of the present invention is to provide an improved sign assembly for motor vehicles.

Other objects of the present invention are to provide a vehicle sign that facilitates rapid changing of the legends; that is free of fasteners that are diflicult to manipulate during sign changing; that allows rapid changing of signs that are permanently but changeably incorporated in the sign assembly; that reduces the likelihood of theft and accidental loss of the sign cards; that is durable and rugged and yet of relatively low-cost construction; and that provides a wide selection of signs in a very compact assembly.

Another object of the present invention is to provide a sign assembly having interchangeable signs bound in a book-like assembly that is rugged and durable; that facilitates permanent mounting of the interchangeable sign on a vehicle or the like; and that facilitates rapid sign changing while minimizing the possibility 0f accidental loss of individual signs.

Other objects, features and advantages of the present invention will become apparent with the following description, the appended claims and the accompanying drawings in which:

FIG. 4 is an enlarged horizontal sectional View taken on line 4-4 of FIG. 2 and also illustrating a portion of the truck body;

FIG. 5 is an exploded view of the sign assembly of FIGS. 2-4;

FIG. 6 is a perspective view illustrating an alternative embodiment of a sign assembly which is shown in an open posltion;

FIG. 7 is a perspective view of the sign of FIG. 6 in a closed position;

FIG. 8 is an enlarged fragmentary vertical section taken along the line 8-8 in FIG. 6; and

FIG. 9 is an enlarged fragmentary horizontal section taken along line 9-9 of FIG. 7.

In FIG. l there is illustrated a sign assembly 10 of the present invention mounted on the trailer 12 of a truck 14. Preferably more than one sign is carried on truck 14, commonly at other conspicuous locations on the trailer 12, such as the front, the rear and both sides of the trailer as illustrated by a second sign assembly 16. Conspicuous display of such a sign identifying the cargo carried by truck 14 is required by law for certain goods. Trailer 12 is illustrated as having vertical corrugations 18 and the width of sign 10 is selected so that the sign may be mounted flat against the body of the trailer 12 between adjacent corrugations 18.

Referring more particularly to FIGS. 2-5, the sign assembly 10 generally comprises a supporting member 20 iixedly mounted on the body of trailer 12. A sign carrier 22 is mounted on support 20 for vertical movement relative thereto from a closed, sign-displaying position illustrated in full lines in FIGS. 2 and 3 to an open, signchanging position illustrated in dashed lines in FIGS. 2 and 3. Mounted on the sign carrier 22 are two booklike sign assemblies, an upper sign book assembly 24 and a lower sign book assembly 26, each of which comprises a plurality of individual sign cards bound together so that a particular sign can be selected when carrier 22 is in its raised position.

More particularly, the supporting member 20v cornprises a generally rectangular backing panel 30 that is mounted directly on the surface of trailer 12 by means of suitable fasteners such as rivets 32. In the preferred ernbodiment, supporting member 20 is made of sheet metal, such as 32 gauge primed aluminum, although other materials may also be used. Along each vertically extending side edge of the backing panel 30 is a forwardly extending

flange

34, 36, respectively. Each

flange

34, 36 has a return bent tab 317, 38, respectively, that extends laterally inwardly parallel to the backing panel 30 and overlying the carrier 22. Each

flange

34, 36 and its

tab

37, 38 extends vertically slightly more than one-half of the height of the backing panel and on the order of twothirds of the height of the backing panel in the preferred embodiment to overlie the lower portion of assembly 24 when carrier 22 is in its lowered position. Backing panel 30 also has an integral horizontal flange 40 along its lower-most edge that serves as a support and stop for the carrier 22. Two integral ribs 42 are spaced apart laterally of the backing panel 30 and extend substantially the full height of the backing panel from -just above the lowermost edge thereof to the upper edge. -Each of the ribs 42 has a generally flat front face 44 and a longitudinal slot 46. Ribs 4.2 and slots 46 serve to slidably support carrier 22 for vertical movement on the supporting member 20.

Carrier 22 comprises a at panel 48 formed along its top edge with a forwardly projecting top flange 50 along each side edge with a forwardly projecting side flange 52. Carrier 22 is also preferably made of sheet metal, although other similar materials, such as plastic, that lend themselves to fabrication of the desired shape may also be used. Carrier 22 is slidably fastened on member 20 by two rivets 56 which extend rearwardly through slots 46 and have a washer 58 thereon at the rear side of ribs 42. Rivets 56 are disposed near the lower edge of carrier 22 to bottom in the lower ends of slots 46 when carrier 22 bottoms on flange 40. Rivets 56 are loose so that carrier 22 slides freely relative to member 20. The height of the ribs 42, the lateral flanges 52, and the

tabs

37, 38 are selected so that the front edge of the flange 52 sildably engages the underside of the tabs 37, 3S.

Each of the book-

like sign assemblies

24, 26 comprises eight individual cards 60 whose height is approximately one-half the height of the carrier 22 and whose width is also approximately one-half the width of the carrier 22. Cards '60 are made of sheet metal, such as 16 gauge aluminum in the preferred embodiment, although other materials may also be used. The individual cards 60 in each of the

assemblies

24, 26 are hingedly connected to carrier 22 by a binder 62 which generally comprises a base plate =64 and four integral hinge tabs, two tabs 66 for the upper sign assembly 24 and two tabs 68 for the lower sign assembly 26. The binder 62 is fastened on carrier 22 by rivets 70 with plate 64 disposed at the rear side of carrier 22.

Tabs

66, 68 have a semi-circular configuration and project forwardly through generally rectangular apertures, two apertures 72 for the upper assembly 24 and two apertures 74 for the lower assembly 26, through narrow slots 76 in cards 60 of the upper assembly 24 and back through apertures 72. A at tab portion 78 at the free end of each tab 66 abuts the rear face of panel 30 to retain the tabs tightly in place. Similarly the lower tabs 68 pass through slots in the cards 60 in the lower assembly 26 and are retained in place by end tab portions 80. Midway between the top and the bottom of the carrier 22 are a pair of struck out tabs 84 which project forwardly underneath the lower edge of the cards in the top assembly 24 to assist supporting the cards in a straight horizontal line.

The

card assemblies

24, 26 are assembled in place on carrier 22 by inserting the

tabs

66, 68 through the

corresponding apertures

72, 74 with the base plate 64 disposed generally perpendicular to the back surface of the panel 48. The cards 60 are then threaded on

tabs

66, 68. The

tabs

66, 68 are then pivoted downwardly in a generally counterclockwise direction, as viewed in FIG. 4, and moved to an extreme position toward the right, as viewed in FIG. 4, so that the

end tab portions

78, 80 can pass downwardly and rearwardly through

apertures

72, 74. The binder 62 is then moved toward the left as viewed in FIG. 4 so that the end tab portions 78, 80l are disposed beneath the backing panel 30, adjacent the

apertures

72, 74. Base plate 64 is then riveted to the carrier 22. In the preferred embodiment, the binder 62 is formed of a relatively stiff sheet metal and the width of

apertures

72, 74 is such that the above assembly operation can be performed without compressing the

tabs

66, 68. However, by using a more resilient sheet metal or other suitable materials, such as plastics, the width of the

apertures

72, 74 can be such that the tabs 66, `68 must be radially compressed in order for the tabs to pass back downwardly through the apertures after the cards 60 are assembled thereon.

With the book-

like assemblies

24, 26 mounted on the carrier 22 as described hereinabove, when the carrier is in a closed position with selected pairs of cards lying flat and disposed side by side as shown in full lines in FIGS. 2 and 3, the

tabs

37, 38 overlie the laterally outward edges of the cards 60 in both the upper assembly 24 and the lower assembly 26 to hold the cards in place displaying a selected sign such as the Flammable Gas sign shown in FIG. 2. When it is desired to change the sign being displayed, the carrier 22 is raised with rivets 56 moving upwardly in slots `46 until the rivets reach the upper ends of the slots. At the upper travel limit of carrier 22, the lower-most edges of the cards in the lower assembly 26 clear the top edge of the

flanges

34, 36 and

tabs

37, 38, as illustrated in dashed lines in FIGS. 2 and 3. The individual cards may then be turned on the 4

tabs

66, 68 to select different signs. After the sign has been changed, the carrier is then moved to its lower position with the cards 60 being again retained in place by the

flanges

34, 36. A suitable lock (not shown) may be provided in the assembly 10 to lock the carrier 22 in the closed position.

In the preferred embodiment, the upper sign assembly 24 and the lower sign assembly 26 have duplicate sets of cards. Side-by-side faces of adjacent cards are printed with a legend such as Flam `on the back of one card and Mable on the front of the adjacent card as shown in FIG. 2. The upper and

lower sign assemblies

24, 26 facilitate the simultaneous display of two different legends, such as Flammable and Gas or Compressed and Gas, one by each of the

assemblies

24, 26. Each of the sign assemblies includes at least one blank, unprinted set of cards so that a single legend such as Poison may be displayed on the other assembly. One legend, or the blank legend, may be provided on the left-hand side, as viewed in FIG. 2, of the back panel 4S and the front of the top one of the cards 60 for display when the cards are all turned to the right-hand position and another legend may be provided on the right-hand side of panel 48 and the back of the back one of the cards 66 for display when the cards are all turned to the left-hand position. Where it is desirable to provide a thinner sign assembly, the cards 60 in the sign assembly 24 may carry legends different from those on the cards in the lower sign assembly 26.

The sign construction disclosed hereinabove may be fabricated simply and economically and requires very few parts and no separate fasteners. A wide variety of legends may be displayed and the legends can be readily changed. It will be apparent that one of the

assemblies

24, 26 could be eliminated providing a corresponding reduction in the height of the sign assembly, but the dual sign assembly, using the upper assembly 24 and the lower assembly 26, is preferred and permits a large number of signs to be displayed in a thin package. Permanent attachment of the cards 60 to the carrier 22, of the carrier to the supporting member 20, and of the member 20 to the truck 14 deters theft and prevents accidental loss of the sign cards.

Referring to the embodiment illustrated in FIG. 6, a sign comprises a generally rectangular support member 91, an upper book-like sign assembly 92 and a lower book-like sign assembly 93. The support member 91 comprises a flat, generally rectangular back panel 94 formed with an integral horizontal flange 96 extending forwardly from along the top edge of panel94 and a lower horizontal ange 98 projecting forwardly from the lower edge of panel 94. Along each side of panel 94 is a forwardly projecting vertical side flange 100. Each flange 100 has a laterally inwardly projecting tab 104 that extends parallel to and overlies the laterally outermost edges of the back panel 94. At each end of the top flange 96 is a horizontal extending slot 97 having its laterally outer end disposed behind the corresponding side tab 104. Bottom flange 98 also has a slot 99 disposed at each end behind tabs 104. The supporting member 91 is made of sheet metal in the preferred embodiment, although it is to be understood that other material suitable for fabrication in the above described member can also be used.

The upper sign assembly 92 comprises a plurality of cards 106 which are bound together and to the upper portion of a pair of card carrier panels 108, 110, respectively. Cards 106 are approximately one-half the width of the back panel 94 and have a height that is slightly greater than one-half the height of the back panel. The carrier panels 108, 110 extend substantially the full height of the back panel 94 between the top flange 96 and the bottom flange 98. The width of panels 108, 110 is approximately one-half the width of the back panel 94. Cards 106 are bound on panels 108, 110 by means of closed, ring-shaped bands 112 that pass through all of the cards 106 and panels 108, 110 so that the cards 106 are permanently and hingedly attached to panels 108, 110. Similarly, the lower card assembly 93 comprises a plurality of cards 116 mounted on the lower portion of panels 108, 110 by means of closed ring-shaped bands 118. The width of cards 116 is again approximately one-half the full width of panel 94 and the height is slightly less than onehalf the height of the panel 94. Although the

cards

106, 116 have been described as having different heights, which construction may be required to display certain legends, it is to be understood that the

cards

106, 116 might have substantially equal heights, approximately one-half the height of the back panel 94, as with the cards 60 described hereinabove in connection with FIGS. 2-5. The

cards

106, 116 are made of stiff sheet metal in the preferred embodiment.

The laterally outer edge of each carrier panel 108, 110 has an integral tubular guide 122 formed by rolling the edge of the panel rearwardly and then abutting the edge against the rear face of the panel. Guides 122 extend the full height of panels 108, 110. Each panel 108, 110 is movably supported on member 91 by a pin 124 that extends downwardly through slot 97 in flange 96, through guide 122 and then through -slot 99 in the lower flange 98. Each end of each pin 124l is formed with a suitable head as at 130 so that the pin is slidably fastened to the supporting member 91. A clasp 134 fastened on the back panel 94 has a snap-over finger 136 yielding movable from an open position shown in FIG. 6 to a closed position shown in FIG. 7.

With the sign 90 having the construction described hereinabove, when pins 124 are moved to their extreme laterally outer positions in

slots

97, 98 with panels 108, 110 lying at parallel to back panel 94, the laterally outer edges of

cards

106, 116 are disposed beneath the side tabs 104. Finger 136 is then snapped forwardly and downwardly against the front face of the exposed cards to retain the

card assemblies

92, 93 in a flat condition with tabs 104 retaining the laterally outer edges of the

cards

106, 116 in place. When it is desired to change the sign, finger 135 is opened to the raised position illustrated in FIG. 6 and the

card assemblies

92, 93 are moved forwardly to their open, sign-changing position by moving the inner edges of the panels 108, 110 forwardly away from the back panel 94. As the center of the

sign assemblies

92, 93 hinges away from the back panel 94, pins 124 slide laterally inwardly in

slots

97, 98 and the outer edges of

cards

106, 116 move out from under the flanges 104 so that the cards are free to be turnedto a desired sign.

The sign 90 described hereinabove may also be fabricated simply and economically and it facilitates the display for a wide Variety of signs that can be changed readily. As with the sign y described hereinabove in connection with FIGS. 2-5, the signs printed on cards 106 of the assembly 92 may be the same as those printed on the cards 116 of the assembly 93 or different signs may be printed on the cards in assembly 92 from those printed on the cards 116 of the assembly 93, depending upon the particular application involved. Although a particular clasp 134 has lbeen disclosed to hold the

assemblies

92, 93 in place, other types of fasteners as well as other arrangements will be readily apparent. For example, a releasable catch to hold each pin 124 in its extreme laterally outward position (FIG. 7) could be used to hold the sign 90 in the closed position illustrated in FIG. 7.
