1. A collapsible baby carriage or doll's pram chassis, comprising at least two lateral chassis posts, which in the erected state extend at an inclination from the bottom at the front rearwardly in upward direction, with push bars provided thereat at an upper side in prolongation and a front wheel arrangement, which is provided at the lower ends or at a bridge part connecting these, with front wheels, two lateral support struts, which are pivotably attached to the chassis posts at a spacing from the lower ends thereof each by way of a respective joint and which have bearings for rear wheels at their lower ends, these ends being offset rearwardly relative to the pivot points, and a seat insert or lying-down insert arranged in the chassis, wherein the inclined chassis posts and the support struts are arranged to be pivotable relative to one another by way of a respective joint and at least one stabilising rod is pivotably provided between the inclined chassis posts and the support struts or at bridge elements respectively connecting these, wherein
the stabilising rod is constructed as a securing rod and is divided by a toggle joint, which folds when the inclined chassis posts and the support struts are led together and which in the extended state forms erection securing means of the chassis frame, an adjusting device is coupled by at least a part of the at least one stabilising rod with an actuating element, which is arranged in the carriage chassis below the insert and by way of which the corresponding part of the stabilising rod can at least be raised by the toggle joint, the actuating element is so arranged below the insert that it is accessible for functional control only after upward pivotation of a seat part of the insert or by removal of the insert, and wherein the actuating element is a yoke element, which at both ends at the joint mounts at the chassis posts or the support struts in the region of the joints can be brought into at least one lower and upper pivot position and acts directly or indirectly on a lifting linkage, a cable pull or chain pull, which raises at least a part of the stabilising rod when the actuating element is lifted for unlocking and, after or during return of the actuating element, the at least one part of the stabilising rod can be lowered into the lower setting, wherein in the unlocked setting the parts can be raised at least to such an extent that a relative folding together of the chassis posts and the support struts is possible, or the actuating element is a pivot lever, a push/pull element or a button and mounted on one of the joint mounts, wherein a Bowden pull, chain pull or cable pull is connected therewith and wherein the Bowden pull, chain pull or cable pull is led upwardly from below to run around a stationary entraining eccentric at a bridge element of the support struts or is attached to a rotatably mounted eccentric disc at the end protruding at the lower side, whilst the upwardly protruding section is connected by way of a connecting element with the part, which is to be moved, of the stabilising rod. |
