Abstract (en)
[origin: US4947960A] It has been necessary up to now for connecting two ladder elements in order to construct a free-standing ladder to connect the lower ends of the ladder elements by means of a tie rod. Furthermore a reliable connection only in the area of the upper ends of the ladder elements is not possible because of the danger of damaging the sidepieces. These disadvantages are supposed to be avoided with the invention. The invention provides, that the clamping elements of a connecting element fastened on a first sidepiece are constructed like a flat contact plate inclined with respect to the longitudinal axis of the first sidepiece and connected to the connecting element and like a swivel plate pivotal about an axis arranged perpendicularly with respect to the longitudinal axis of the first sidepiece. The connecting element of the invention can be used in all types of multi-purpose ladders.
