ABSTRACT:
A self-erecting control device is provided with a base member and a bracket assembly attached to the base member for receiving a movable sign support member. The movable sign support member is vertically movable and rotatable with the bracket. That is, in one position the sign support member is stationary in an upright position and in a second position, the movable sign support member is rotatable into a storage position. A flexing device, such as a spring, is mounted to the movable sign support member and a sign wherein upon impact the sign device yields in response to the impact and the coil spring returns or self-erects the sign to its original upright position.
