7 Claims.

This invention relates to signs and particularly to an advertising sign which is supported in display position by flexible tensioning elements such as cords, ropes and the like.

An important object of this invention is to provide an inexpensive sign structure of the type supported by flexible elements and such a sign structure which is protected in a novel manner from damage or tearing as a result of the tension imposed 'by the supporting elements. An important object of the invention is to provide a novel reinforcement for the sign which absorbs the strains imposed thereon and which reinforcement is constructed and associated with the sign so as to be concealed from view. Another important object of this invention is to provide a reinforcement for signs which not only absorbs the forces and strains which would otherwise likely damage the sign but also stiifens portions of the sign against movement such as that caused by air currents.

Various other objects, advantages and meritorious features of this invention will become more fully apparent from the following speciflcation, appended claims and accompanying drawing, wherein:

Fig. 1 is a view in elevation of a portion of a sign constructed in accordance with this invention,

Fig. 2 is an enlarged detail view showing the manner of assembling the reinforcin strip in the sign and connecting the same to supporting tensioning elements, and

Fig. 3 is a cross-sectional view of a portion of Fig. 2 along line 3-3 thereof showing the reinforcement in completely assembled condition.

The reinforcement extends between the tension supports of the sign yet is concealed from View. It is fashioned so that it lies Within the outside dimensions of the sign and substantially in the plane thereof. The reinforcement is shaped so that its main dimension will extend parallel to the plane of the sign. It is thus capable of being inconspicuously enclosed within folds of the sign.

Referring to the drawing, the sign proper is indicated at III. A fragment or right portion is illustrated in Fig. 1, it being understood that the remaining or left hand portion is constructed and supported in the same manner. The body of the sign is composed of flexible material such as textile fabric, fiber or otherwise.

The sign is usually supported in vertical or upright position but may lie in any other plane if desired. For support, flexible anchoring elements indicated at l2-l2 are generally employed. Cord, rope, tape or the like may be used for the supporting elements. Rope or cord is shown in the illustrated embodiment of the invention. The cords |2|2 extend along opposite sides of the sign, the margins of the latter being folded thereover as indicated. Instead of two cords extending the length of the sign and projecting from the opposite sides thereof, four separate cords each attached to a corner may be used. In either form of support the cords exert a tension or strain upon the sign particularly when the cords |2-|2 illustrated diverge away from one another to maintain the sign in taut condition in the wind.

It is the purpose of the present invention to provide a novel form of reinforcement whic absorbs'the strains which would otherwise be imposed on the body of the sign by the supporting elements or cords |2-l2. The novel form of reinforcement comprises a relatively flat band of metallic material preferably of relatively stiff character. The band, however, is preferably deformable under pressure so that it may be easily folded over upon itself. Such a band is desirable at each side of the sign and conmeeting the two supporting cords Il -I2 at their point of entrance into the sign. Additional bands may be stretched across the sign at intermediate points along its length, if desired.

In the drawing a metallic reinforcement of this character is indicated at M. It extends along the loose side of the sign transversely to the cords I 2I2. A similar band may be used at the other end of the sign. The ends of the band l4 are folded over the cords l2--|2 and the folded portions secured to the main body of the band in any suitable way such as by metal stitching. The reinforcing band is assembled upon the body of the sign before the cords are attached thereto. In the assembly operation the band is preferably positioned a slight distance inwardly from the side edge of the sign so that a marginal portion of the sign body can be folded over the band in the form of a hem concealing the band therewithin. This is illustrated in Fig.2. The marginal portion indicated by the reference numeral I6 is folded over the band and secured by stitching l8 to the body of the sign. A reinforcing band is similarly applied to the other side of the sign.

The body of the sign with the reinforcing metal bands therein is now ready for attachment to the supporting cords l2l2. This is -to the main body of quickly and easily accomplished by folding the sides of the sign over the cords as previously described. In the course of doing this the ends of the metal reinforcing bands are folded over the cords in the manner illustrated in Fig. 3. Metal stitching 20 is suitable for securing the folded ends of the bands to their respective main body portions. Because of the flat character of the reinforcing bands and the fact that they are concealed within folds of the sign, there is no evidence when the sign is viewed from a distance of the presence of transverse metal supports for the sign.

Any tearing strain which the cords might impose on the body of the sign is taken by the metal bands. An important advantage of employing flat bendable stiffeners is found in shipping the signs after they are made. The signs can be folded into a small bundle, the flat stiffening bands being bent and folded to the desired minimum size for shipping. This does away with the necessity of cartons or additional wrapping material which would be required by rigid or semirigid stiffening members.

Another desirable feature of the structure is the fact that a fabric portion of the sign body is interposed between the metal reinforcing band and the cords l2. This provision plus the flat character of the band prevents the metal band from chafing the cords and cutting through. suf flciently far to cause the cords to break under the strains imposed. The flat character of the reinforcing band distributes. the tension over a relatively wide area in contrast to a narrow rodlike type of reinforcement.

WhatIclaim is: V

1. A sign comprising a flexible sheet, a pair of tensioning. elements extending parallel. to one another along two opposite sides of the sheet, a flat bandof bendable metal material extending transversely to said tensioning elements and en closed wholly within a fold in the sheet, marginal portions of said sheet together with the ends of said band being folded over said tension elements, and ,m eanssec uring the folded portions of the sheet and the band tothe main body portions thereof to secure the sign to the tensioning elements."

2. In combination with a sign having a pair of flexible anchoring elements extending from substantially each corner at one dimension of the sign and disposed at a distance apart to normally maintain the sign flat, a flat band of bend able metal material bridging and connecting said anchoring elements, sign folded over said metal band forming a sleevetype, hem concealing the latter from view therewithin, said hem and the band therewithin being folded about the tensioning, elements so as to interpose the marginal portion of the sign between the metal band and the. anchoring elements.
