one end of the coil spring 102 is secured to the roller 84 by a suitable fastening means such as a wood or machine screw 104 the other end of the coil spring 102 is received within an aperture 106 or secured by other suitable means to the stub shaft 90 thus the coil spring 102 provides rotational bias to the roller 84 in a manner similar to the spring in a window shade it should be understood however that no catch or latch means is included in the present device and that the rotational bias provided by the spring 102 once the roller 84 has been rotated to tension the spring 102 will be constantly applied to the roller 84 secured to the outer surface of the roller 84 and wrapped thereabout when stored is a flexible sign 110 the housing 82 also defines an elongate slot 112 which is slightly longer than the width of the sign 110 through which the flexible sign 110 may pass referring now to fig6 it will be appreciated that the sign 110 may be a solid material such as heavy gauge polyethylene or similar plastic material having good strength as well as flexibility at low temperatures canvas or an open weave fabric such as illustrated to minimize the wind resistance of the deployed sign at each corner of the sign 110 farthest from the housing 82 when the sign 110 is extended therefrom is a eyelet or grommet 114 one of which is illustrated in.
