A TI'ORNE'ZST United States Patent F DISPLAY SIGNS GilbertC. Jacobs, Milwaukee, Wis., assignor to Everbrite Electric Signs, Inc., Milwaukee, Wis., a corporation of Wisconsin Application November 21, 1956, Serial No. 623,568

9 Claims. (Cl. 40125) This invention relates to improvements in display signs, and more particularly to an.illuminated display sign with plastic sheet facings which is susceptible of .be- .ing built in mammoth sizes.

Illuminated display signs have heretofore been provided with plastic sheet material facings and such signs have 'also heretofore utilized corrugated sheet material for the facings, but have been of limited size because the plastic sheet material comes in predetermined limited widths and it is necessary to provide in a sign having a transverse dimension considerably greater than the width .of a sheetof plastic facing material, suitable weatherproof joints between the abutting margins of the longitudinal edges of the sheet material, which joints, besides being weatherproof, .will not detract from the exterior appearance of the sign, nor interfere with the proper transmission of light through the sign faces.

With the foregoing in mind it is a primary object of thepresent invention to provide a mammoth illuminated display sign having plastic corrugated sheet material faces in which the strips of facing material of limited width are joined together 'along their adjacent longitudinal edges by eifective non-visible weatherproof joints which do not interfere with the transmission of light through the sign facings.

A further more specific object of the invention is to provide a corrugated sheet material facing for a relatively large display sign wherein the adjacent side margins of the facing strips are secured together by effective weatherproof non-visible joints arranged to also receive at the joints the outer or forward ends of tie rods or hangers used to anchor the large compositefacing sheets to the sign framework.

Afurther more specific object of the inventionis to provide in a mammoth illuminated display sign, a light transmitting corrugated plastic sheet material facing with joints between the adjacent marginal edges of the strips which compose the entire facing also receiving and anchoring the outer ends of tie rods or hangers in amanner to prevent light leakage and dirt entrance at the joints so that the outer surfaceof the sign facing will present an unmarred overall appearance, notwithstanding its large size.

The provision and erection of a'mammoth display sign frame involves a very substantial expense audit is impractical to take the sign frame down or dismantle'it should it be desired to change or vary the advertising display on the sign face from time to time. It is, therefore, another object of the present invention'to provide a mammoth display sign of the type described wherein the advertising indicia or displays on the facing of the sign may be readily removed, changed and repositioned whenever desired with a minimum of efforgand without the necessity of taking down or dismantlingthe frame structure or any portion of the sign.

A further object of "the invention istoprovid'e in a mammoth sign of the character described having corrugated sheet material facings, readily removable and 2,823,473 Patente claFeb. 18, 1958 ice ably engage ribbed portions of the sign facing whereby the advertising letters or displays may be easily and quickly removed from theerected sign and facing at any time for the mounting of'new or difierent advertising indicia and displays.

A further object of the invention is to provide in an illuminated display sign with corrugated sheet material facings, advertising display indicia mounting clips or fasteners which engage the inner-faces of the advertising display letters or indicia so as not to be visible and which removably and adjustably engage the longitudinal ribs in the corrugated faces of the display sign for selective non-visible securement thereon.

A furtherobject of the invention is to provide a mammoth display sign of the character described which per- .mits'the ready mounting on its face portions of interchangeable advertising displays, which is weatherproof for outside usage, which is attractive in appearance and presents unmarred display facings, which provides for the non-visible anchorage of the large sheet material facings, which is strong and durable, and which is well adapted for the purposes described.

With the above and other objects in view, the invention consists of the improved display sign, and its parts and combinations as set forth in the claims, and all equivalentsthereof.

ground or otherwise erected in an elevated position. The

display faces of the sign 'mayreach such relatively large proportions as, for instance, 'forty feet in height or the longest-dimension, and twenty-five feet in width or the transverse dimension. While the sign may take any desireil'shape, it isillustrated'as being of rectangular form with 'thelongestdimensi'on -'df the frame for the display "faces being-vertical. 'Where the gigantic display sign is to be erected from the ground, suitable spaced apart upright supporting posts are provided which may, if necessary, be braced by diagonally extending suitably anchored cables or supports 11. Between portions of the uprights there is the display sign proper which includes an open box section rectangular frame 12 carrying spaced apart transverse supporting pipes or bars 13 whose opposite end portions are anchored in the uprights 10. Within the frame are a plurality of suitably mounted illaminating tubes 14. The sign may be either of the single face or double face type. In the latter case each face of the box-like open frame 12 is covered by a facing generally indicated by the numeral 15 and which forms the particular subject matter of the present invention. Each facing is a composite translucent or transparent sheet of corrugated plastic material wherein the corrugations run lengthwise of the sign frame or co-extensive with its longest dimension.

In view of the small scale of the drawings the vertical corrugations in the facing strips 15' could only be schematically indicated in Fig. l and in the major portion of Fig. 2. In the latter view in the upper left-hand corner the ribs and recesses of the corrugations are shown in a fragment of the facing, but it should be understood that in a complete facing these ribs and recesses cover the entire facing.

Corrugated plastic material of the type suitable for a sign facing is available in strips of very limited width (in practice, about twelve inches), but these strips of plastic material are available in unbroken lengths adequate for the longest dimension of the sign frame. Obviously with a frame of twenty-five feet in width, for instance, to provide a complete facing the corrugated plastic strips which extend lengthwise of the frame must have their adjacent longitudinal edges secured together. The present invention provides means for accomplishing this end so that any number of strips may be secured together to provide an integral composite frame facing which is weather proof and in which the joints are not visible exteriorly of the sign and which do not detract from the display face of the sign.

Referring now more particularly to Fig. 3 there is illustrated in large form a transverse sectional view through a strip of facing material 15' having its opposite longitudinal edges secured to the in-tnrned tongue portions of the next adjacent facing strips 15', said view being taken approximately along the line 33 of Fig. 2 on a larger scale. As shown, the strip of plastic facing material 15' is formed with alternating forwardly projecting ribs 16 of frusto-conical formation and inwardly extending recesses 17 of similar formation. The diagonally extending legs between the ribbed and groove portions are formed with recesses 18 for the purpose hereinafter to be explained. The longitudinal marginal portions of each facing strip 15' have inwardly directed diagonal legs 19 which are bent laterally as at 20 in alignment with the inner ends of the recesses 17 and are then provided with rearwardly directed right angular tongue portions 21. The tongue portion 21 on one margin of a strip 15 may have a laterally projecting squared shoulder 22, while the tongue portion 21 on the other margin of a strip 15 is provided with a squared recess 23. Thus when the facing strip 15 of a composite frame face is interposed between and connected to the longitudinal margins of a pair of adjoining facing strips 15 the tongue portions 21 of the interposed strip will abut the tongue portions 21 of the adjoining strips with the shoulders 22 entering the adjacent tongue recesses 23. Adjacent the overlying tongues 21 at each joint there is the forwardly projecting pintle plate 24 (see Fig. 4) of a hinge structure and the pintle plate is secured to the overlying tongues 21 by pins or screws 25 which also extend through the overlapping adjacent tongues 21 and connect the same together in a firm manner so as to make the joint weatherproof and invisible from the outer face of the sign. The rearwardly projectassume ing tubular portion 24' of the pintle plate 24 carries a pintle 26 which also extends revolubly through the tubular portion 27' of another pintle plate 27 to which is anchored the forward end of a horizontal inwardly directed facing anchor bar 28 which extends from and is secured to any of the interior frame members of the sign structure, as the members 13, whereby the composite facing through the anchor bars 28 secured at the longitudinal joints between adjacent facing strips 15, securely mounts the composite facing sheet on the sign framework.

The plasti sheet material which comprises the sign facing 15 may, due to weather, expand or contract in its longitudinal direction, and due to the fact that the vertically aligned portions 24' and 27 of each hinge structure are slidably mounted on a pintle 26 there can be longitudinal movement of said pintle plate portions on the pintle to permit relative longitudinal movement between the marginal portions of connected facing strips 15 and the shoulder and recess joints 22 and 23 between the adjacent tongues 21 of the strips also permit this relative sliding movement.

It will thus be seen from Figs. 3 and 4 that any number of elongated facing strips 15' may have their adjacent longitudinal edges connected together by the form of joint illustrated and described to effect a mammoth sized sign facing of any desired width. The joints do not in any manner mar the external appearance of the composite facing, but effect very excellent weatherproof joints which may move in the longitudinal direction and which also provide anchorage for the facing mounting rods or bars 28.

A slightly modified form of facing strip 15" is shown in Figs. 6, 7, 8 and 9 wherein the alternating ribs and recesses do not have the depth of the ribs and recesses of the form of facing strip 15' shown in Figs. 3 and 4. Also, the legs at the extremities of the ribs and recesses are obliquely directed and form acute angles with the shoulders of the ribs and recesses. Each facing strip 15" of the modified form has its side longitudinal edges formed with rearwardly turned right angular flanges 21' whose inner extremities are bent laterally right angularly to pro-' vide heads 29. Thus it will be seen that at the joint between the side margins of a pair of adjacent facing strips 15" the flanges 21' contact one another and the heads 29 co-operate to form with the flanges 21a T which is vertically slidably engaged by an enclosing sleeve 30 which has secured thereto the forward end of a horizontal inwardly directed angle iron anchor bar 28', The inner end of the latter may be connected to any of the framework members within the sign frame 12, whereby the composite facing is anchored to the interior framework of the sign. The sleeve 30 may slide longitudinally on the head of the T formed by the adjacent portions 29 and the complementary shoulder and recess portions 22 and 23 with which the abutting flanges 21' are formed permit relative longitudinal movement as between adjacent facing strips 15' and the facing strip flanges to compensate for contraction and expansion.

Referring again to the principal form of facing strip 15' shown in Figs. 3 and 4, the forwardly projecting ribs 16 of the corrugations provide convenient means for the adjustable mounting on the facing of display letters 31.or advertising indicia or designs. These advertising letters, indicia or display designs may take any desired form and be of any size and may be mounted on any desired outer surface of the composite sign facing 15 as is shown most clearly in Fig. 2. For the purpose of anchoring the letters or display designs 31 to the sign face 15, clips are utilized, and the preferred form of clip for use with the type of corrugated facing 15' shown in Figs. 3 and 4 is illustrated in detail in Fig. 5 and is designated by the numeral 32. A clip 32 actually comprises a pair of complementary reversely directed angularly shaped elements having angled head portions 33 which underlie a rear surface portion of an advertising character 31 and are secured thereto by screws 34 or other suitable securing means. The pair of elements comprising a clip 32 provides an inner embracing portion co-extensive with the breadth of a facing strip rib 16 and overlying the same as best shown in Fig. 3. The opposite extremities of said rib embracing portion have in-turned flanges 35 which extend into the recesses 18 in the diagonal leg portions of the facing strip corrugations. The clips 32 can be somewhat resilient so that the engagement of the flanges 35 within the recesses 18 may be secure and a clamping effect is obtained by the tightening of a nut 36 on a bolt 37 which connects portions of the clip elements together. The clips may be mounted on display letters or design characters 31 at desired intervals along the length of the same but should be secured to the advertising characters 31 so as to coincide with spaced-apart facing strip ribs 16 which are to be engaged thereby. Obviously the en gagement of the character-carried clips with spaced ribs on the facing strips permits positioning of the advertising display characters 31 on any desired portion of the com posite facing and permits the advertising characters 31 to be adjusted vertically on the facing strip ribs 16. It will also be evident that by releasing the nuts 36 the clips 32 may be completely disengaged from the facing strip ribs. Thus the facing of the sign may be easily supplied with interchangeable advertising'characters 31-or displays from time to time to vary the character of the sign. This is accomplished without taking down the sign or dismantling it in any manner. The clips are easily removable from the advertising characters 31 and may be secured to any other sets of characters 31 which are to replace those initially mounted on the sign facing.

In Fig. 6 there is disclosed a modified form of advertising character clip 32 which merely differs from the clip of Fig. 5 in that it is shaped to exactly conform with the shape of the rib of the modified strip 15". The in-turned end flanges 35 of said modified type of clip engage the oblique end walls of a rib within the acute angles between the ribs and the recesses of the corrugations.

Figs. 8 and 9 illustrate a second form of modified advertising character mounting clip 32". This clip 32 is preferably kidney-shaped and slightly longer than the distance between the side margins of the recess of a facing strip 15". The clip 32' is also formed of plastic or other slightly yielding material and is pressed or wedged into the recess of a facing strip 15 and is frictionally retained therein. Projecting forwardly centrally from the body of the clip 32' is a hollow stem 37 which is internally threaded in order that a suction cup (not shown) may be attached thereto which engages the inner face of the advertising character 31, or a screw or other attaching means may connect the advertising character to the stem 37.

From the foregoing description it will be apparent that pursuant to the present invention a mammoth illuminated display sign may be provided having light permeable display faces of corrugated sheet material of any desired size which are assembled from strips joined together along their longitudinal margins by very effective joints. These joints efiiciently seal the interior of the display sign frame against the entrance of rain and snow and prevent leakage. The joints are furthermore so effected within the channeled portions of the corrugated facing strips that they do not in any manner affect or mar the exterior surface appearance of the composite facing and furthermore provide nonvisible means for the anchorage of the outer ends of bars or rods which secure the large facing to the sign frame structure. The joints and anchorage securement permit movement of the facing strips to compensate for expansion and contraction.

The mammoth sign with its novel face construction is arranged to quickly and easily receive advertising displays, lettering and other types of display characters or designs which may be interchangeably mounted on the sign facing in any desired position and arrangement, and the manner in which the letters or advertising characters are mounted permit proper adjustment or positioning of the same on the facing without removing the facing or in any manner dismantling the sign. Simple means are provided for adjustably mounting the advertising characters on, the corrugated portions of the outer face of the sign facing and whenever it is desired to change the display on the sign facing, this is easily and quickly accomplished. The improved display sign is of simple and novel construction, is extremely practical and efficient in use, and is well adapted for the purposes described.
