Abstract
Abstract A road traffic warning light has a block-shaped housing composed of superposed housing elements. Adjacent housing elements are interconnected by a joint so that they may be folded to collapse the housing while the housing elements form a column when erected. A warning light transmitter is mounted on each housing element.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
A road traffic warning light comprising a block-shaped housing composed of at least two superposed housing elements, a respective joint pivotally interconnecting adjacent ones of the housing elements for enabling the housing elements to be folded, a respective holding element between the adjacent housing elements for enabling the housing elements to be erected to form a column, a warning light signal transmitter mounted on each one of the superposed housing elements, and means for stabilizing a lowest one of the superposed housing elements in an erect position, the stabilizing means comprising a support and the housing elements consisting of a lowest housing element projecting substantially perpendicularly from the support and a superposed one of the housing elements adjacent the lowest housing element, the lowest housing element having an upper rim and a free space being defined between the support and the lowest housing element, the joint pivotally interconnecting the housing elements at a side of the upper rim adjoining the free space, and the superposed housing element having a volume and shape corresponding to the volume and shape of the free space.
Claim 2
Dependent Claim
182 words
A road traffic warning light comprising a block-shaped housing composed of at least two superposed housing elements, a respective joint pivotally interconnecting adjacent ones of the housing elements for enabling the housing elements to be folded, a respective holding element between the adjacent housing elements for enabling the housing elements to be erected to form a column, a warning light signal transmitter mounted on each one of the superposed housing elements, and means for stabilizing a lowest one of the superposed housing elements in an erect position, the stabilizing means comprising a support and the housing elements consisting of a lowest housing element projecting substantially perpendicularly from the support and a superposed one of the housing elements adjacent the lowest housing element, the lowest housing element having an upper rim and a free space being defined between the support and the lowest housing element, the joint pivotally interconnecting the housing elements at a side of the upper rim adjoining the free space, and the superposed housing element having a volume and shape corresponding to the volume and shape of the free space.
