A self-returning sign panel comprises: a frame including a bracket having one open side, having a space formed therein, fixed onto a wall surface or a pillar, and including a projection groove, and a cam unit formed with a projection shaft to be inserted in the space formed in the bracket and coupled with a projection groove on an outer surface thereof and with a cam unit having a cam groove with one open side; a body; a cam slide coupled with an insertion groove formed in the body, having a spring on one inner side and an adhesion surface and an adhering protrusion in a place adjacent to the adhesion surface which are formed in the other outer side; a fixing unit; and a coupling member including a first member and a second member, wherein the first member is formed with a fitting groove which is adhered to a lamp groove formed in a support of the body and is configured to insert a light guide plate formed on the fixing unit, and with a fitting unit which is coupled with an assisting hanging protrusion formed on the support of the body, and the second member has an adhesion groove formed in one side thereof to be adhered to the body and includes a light guide coupling groove formed in the other side thereof to be adhered to the light guide plate of the fixing unit. According to the present invention, the cam groove of the cam unit formed on the frame has a diameter becoming smaller from the center towards both sides, so the sign panel can autonomously return to an original state by the spring coupled with the cam slide sliding from the cam groove due to the properties of the spring returning to the center of the cam groove, even when the body is rotated by wind or external impact. Accordingly, the body can be prevented from being damaged by wind, and a user can conveniently perform maintenance. |
