Abstract
What is described here is a device for facilitating the locomotion of a person by himself or herself by means of a spring system for removable attachment to both legs of the person, which spring system enables the person, by compression and deflection of at least one spring element, to walk on the ground by jumping step by step. The invention is distinguished by the provisions that the spring element is a leaf spring having an arc-shaped configuration, on the concave side of which a leverage mechanism is provided that is fixedly connected for rotation to the leaf spring via two separate fixing means and a base plate on which the respective foot of the person may be placed and which is connected, on the one hand, via at least one rotary pin bearing and one connecting rod to the first fixing means and, on the other hand, to the other fixing means either directly or via a central support rigidly connected to the base plate.
