Abstract
Abstract Disclosed herein is a warning device for stalled vehicles which comprises a lazy-tongs type frame, signal means made of flexible material attached at its upper and lower ends to the frame and overlying one face of the frame, and means connected to the lower end of the frame mounting the device on the roof of a vehicle. The flexible material forming the signal has an extra length at its upper edge depending from said upper edge on the other face of the frame, for wrapping around the device when the frame is collapsed for storage.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
A warning device for stalled vehicles comprising a. a lazy-tongs type frame expansible for use as a signal material support, b. signal means made of flexible material attached to the upper and lower ends of the frame, and overlying one face of the frame, c. an extra length of said flexible material depending from the upper edge of said signal means material on the other face of the frame, and d. mounting means connected to the lower end of the frame for mounting the warning device on the roof of a vehicle.
Claim 2
Dependent Claim
92 words
A warning device for stalled vehicles comprising a. a lazy-tongs type frame expansible for use as a signal material support, b. signal means made of flexible material attached to the upper and lower ends of the frame, and overlying one face of the frame, c. an extra length of said flexible material depending from the upper edge of said signal means material on the other face of the frame, and d. mounting means connected to the lower end of the frame for mounting the warning device on the roof of a vehicle.
Claim 3
Dependent Claim
46 words
The device defined by claim 1, in which the flexible material of the signal means is provided with a pocket extending transversely across each of its upper and lower ends, and a rigid bar in each of said pockets attached to the ends of the frame.
Claim 4
Dependent Claim
27 words
The device defined by claim 1, in which the extra length of flexible material is foldable over the frame and signal means when the frame is contracted.
Claim 5
Dependent Claim
57 words
The device defined by claim 1, in which the mounting means comprises a pair of vertical arms connected pivotally to the bottom end of the frame, and suction cups on the arms, said mounting means being pivotally movable to move the suction cups into contact with the bottom end of the frame for storage of the device.
Claim 6
Dependent Claim
160 words
A warning device for stalled vehicles comprising a. a lazy-tongs type frame expansible for use as a signal material support and collapsible for storage of the device, b. flexible signal material substantially rectangular in shape overlying one face of the frame, c. a rigid bar attached to each of the upper and lower ends of said signal material and attached to the respective upper and lower ends of the frame, and d. mounting means attached to the lower end of the frame including suction cups and vertical arms connecting the cups to the frame for mounting the device in vertical position on the roof of a vehicle, said frame comprising two short pivotally connected bars at each frame end and a plurality of crossed pivotally connected longer bars intermediate said short end bars, the pivotal connections between the short bars at each frame end also serving to connect the short bars to the rigid bars attached to the signal material.
