Warning marker

Abstract

The present invention is a practical new-type warning marker, which is composed of several multilateral taper layers of the same taper (gradient) with the bottom layer as its base. The top taper layer is pulled upward to drive the middle taper layers move so that the bottom, middle and top layers are clutched in position successively. Once a road damage or a car breakdown happens, said practical new-type warning marker is put on the ground or hung on the cover of the rear luggage case of the car to warn the passengers or/and the cars following behind with an appearance of a polyhedral solid triangular state. The warning marker is easily and stably erected and can be restored freely so that it improves the security of warning.

What is claimed is:  
     
         1 . The present invention is a warning marker, including a bottom taper layer, a top taper layer and several middle taper layers. Each taper layer is constructed of the same taper (gradient) with the bottom taper layer as the base. The movement of the top taper layer drives the middle taper layers, which is characterized by: The bottom taper layer is a frame board where there is a taper post of certain taper (gradient) protruding upward at each corner. Between said taper post and another taper post there is a thin frame board with a fixing protruding strip set up on its inner edge, and at both lower side edges of said thin frame board there is also a connecting board connecting with its neighbouring taper post respectively. The top edge of the inner side of connecting board appears to be a vertical oblique face, and each side of the taper post, thin frame board and connecting board together forms an inclined frame plane and a protruding post serving for erecting a bearing board is setup at the back of the frame board of the bottom taper layer. The top taper layer is a quadrilateral taper body and at its top a hole is established to allow a hook inside the top taper layer to pass through. The middle taper layer is a taper frame of which dimension of its upper frame is smaller than that of the bottom frame, and on the upper frame of middle taper layer a fixing protruding strip, thin frame and gap are set up as the same as those of the bottom taper layer. A connecting hole is made up at the lower side of the thin frame board and the inner top edge of connecting appears to be a vertical inclined plane.
