Highway signs and flags capable of being rolled up

A flexible, highway safety sign capable of being rolled up for storage and portability and mounting a highway flag comprising a flexible message panel having a quadrilateral configuration capable of being rolled up for storage or transportation and rolled open to assume a substantially flat message displaying configuration, bracket means secured adjacent each corner of said message panel, the bracket being constructed and defined with individual sockets for receiving and removably securing an end of each of a pair of flexible sign cross-members on one side of the panel, a pair of flexible sign cross-members pivotally secured to one another intermediate their ends for permitting the members to be pivotably folded between a side by side position, and to be pivotaly unfolded to an orthogonally related open relationship, one end of each of said cross-members being removably mounted in an individual socket for the flexible message panel to cause the message panel to assume a substantially flat message displaying configuration, the cross-members being constructed and defined with sufficient stiffness to normally maintain the flexible meassage panel in an upright message displaying position and yet sufficiently flexible to be flexibly responsive to winds and wind gusts impinging thereon to tilt in accordance with the strength of said winds without breaking or becoming physically distorted and to return to its upright position upon the cessation or dimunition of the winds or wind gusts, and clamping means secured to one of said cross-members adjacent to one corner thereof and secured in a preselected position on said one cross-member without fasteners extending through the cross-member, said one cross-member being secured to said individual sockets for positioning the clamping means adjacent one corner of said message panel when the cross-members hold the message panel in a flat message displaying configuration, said clamping means being constructed and defined for pivotally securing at least a first flag arm in a flat displaying position extending outwardly of said message displaying panel from one side thereof and pivotable to a storage or portability position aligned side by side with the folded cross-members thereby allowing the flexible message panel to be rolled around the cross-members and flag arm when said panel is detached from the cross-members, said clamping means comprises a pivot plate having first and second spaced sections for pivotably, individually securing a flag arm to each of said sections, each section having a pivot pin secured thereto so that the pivot pins are arranged on each section in alignment with one another, the pivot plate including a third section arranged at a different elevation than said first and second sections adjacent the ends of said first and second sections securing the pivot pins and having a pair of bridging portions extending between said third section and an individual one of said first and second sections for arresting the movement of a flag arm pivotably secured to the individual pivot pin of one of the first and second sections, each of said first and second sections including at least a single upstanding element arranged on the first and second sections including at least a single element arranged on the first and second sections in spaced relationship to the pivot pin and said arresting portions of the third section for confining the end of a flag arm secured to the pivot pin to a flag displaying position, said pivot plate being further characterized as being yieldable to forces applied to a flag arm secured to a pivot pin to cause the flag arm to move over the upstanding element for positioning the flag arm in a non-displaying position, and a mounting plate adapted to be secured to said one cross-member and to the pivot plate for clamping the cross-member therebetween, the mounting plate overlying the pivot plate on the side thereof having the pivot pins and secured to the pivot plate at said third section, thereby permitting a flag arm to extend outwardly of the secured plate to permit said pivotal movement of a flag arm secured to either pivot pin, and fastening means for securing the mounting plate and pivot plate together.
