Priority; Patent application in France on 9 October 1946 _e

The -gWtfa invention aims to develop light handcarts, in particular strollers, in such a way that the same can be easily and quickly folded very flat ζ us aminen 'for the purpose of convenient inquiries »

In the feaigÄäägi »© * drawing there is an example of an embodiment of the subject of the invention, as a pram with low frame, shown "

Fig.l is a side view of the stroller in the unfolded state and / or in the driving position j

Fig. Z is a plan view of Abbel;

Fig »3 the trolley folded up _and ready to be carried j

Fig.4 is a half front view of the wagon viewed from the drawbar;

Fig * 6 the corresponding top view to Fig.5

The two cross winds Jl and B _{1 also} serve as queries for the wagon wheels, which are in the same plane as the walls. On the back of the car these walls _{are connected to one another by two axles C 1} and I) which are attached to the base of the drawbar 1

The two axes C, and JD are parallel both below and with the crosswinds j ± and B ₁ and occupy such a position that they / gA ^ tZ ^ y

«£ -f coincide with the bisection line xy of the angle 0, which is bounded above the wagon profile, on the one hand by the upper edge of the side walls A. and B _- and on the other hand by the drawbar E" f

run with the drawbar B Bvmp-trisch, at the lower inde they are hinged to a äfW ^^ o ^ anflenear-Qtierstab JT, as well as to two support arms G ₁ and JJ, which are firmly connected to the side walls _A and B ₁ are"

The length m of the transverse rod J and the sum of the two, while the lengths of the two support arms (n + o) are added together, result in the total carriage width j) _e

line 3ede of the two equal arm lengths _n and _o corresponds to half the length of the crossbar j; the drawbar Jl.

Under these circumstances, the operation of the clamping device is as follows;

When the cart is unfolded so that it is in

In the driving position, turning back the two side walls A. and B ₁ in the sense of the bow E causes them to be _{rotated about their axes C -} and I) until / 1

The collapsible baby carriage so described is not only simple in construction; he fee®ü &% also in great strength and is only light in weight. The invention can of course also be applied to other types of wagons with four or even only two wheels and, in addition, modifications can be made within the same framework *. - ^ nhnt-z.-hp.re i r »h varT asHflti PA5MTANSPRUGH.
