  • Patent number: 4679652
    Abstract: A ladder support has pedestals universally mounted so as to accommodate irregular ground surfaces. Each pedestal is an enlarged circular affair providing frictional engagement with the ground plane. A pair of spring-loaded jaws extend parallel to one another for receiving the lower end of the ladder, and which, due to the weight of the ladder, are levered against a resistant spring force causing the jaws to close on the end of the ladder and secure it by clamping engagement. The jaws are mounted on end plates which are, in turn, pivotally mounted onto end wall assemblies that can rotate providing a self-adjustment of the lower end of the ladder between the jaws.
