Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
183 words
In a portable warning device for use in being removably mounted on a support such as a vehicle, containing a flexible warning sign with an upper edge and a lower edge and being adapted to be rolled up and unrolled, respectively, two rod-like reinforcements each having a longitudinally extending convex external surface and a longitudinally extending flat internal surface, said upper and lower edges of said sign being connected to the flat surfaces of said reinforcements, respectively, and attachment means comprising elastic band means extending along at least a portion of said longitudinally extending flat surfaces of each of said reinforcements and being secured near their ends to the end portions of said reinforcements; clamping means respectively coupled to a central portion of said elastic band means of each of said reinforcements, each clamping means including a projecting attachment portion substantially matching the contour of said longitudinally extending external surface for being clipped thereto during the rolled-up condition of said warning sign, whereas in the unrolled display condition of said warning sign said clamping means serve for being disconnectably mounted on a support.
