L. G. MAClP FOLDING CARRIAGE FOR CHILDREN ZSheets-Sheet 2 Filed June 22, 1944 Wm. M I a 6 L Patented Aug. 24, 1948 UNITED STATES PATENT OFFICE Application June 22, 1944, Serial No. 541,623 In Spain July 16, 1943 1 Claim. 1

The present invention refers to a new folding baby carriage for carrying children in a lying down position, characterized and distinguished essentially from all similar carriages known up to the present, by its extreme lightness, considerable robustness, small size in its used positionwhich is reduced to the minimum when folded up-and simple construction free from complications, rendering its handling extremely easy.

At the present time there are known a considerable quantity of types of baby carriages for carrying children, and their use is general. These have superseded the old custom of carrying children in arms, with all the inconveniences attached to this custom, but due to their characteristics these carriages in their turn have certain inconveniences. Amongst these may be cited, in the first place, their excessive weight and volume possessed by the majority, making their moving difiicult, and above all, their clumsy handling for taking them upstairs and stowing them away in a reduced space.

The above reasons may be the cause occasionally of abandoning these means of transport, as the convenience of their use in the street is offset by the troublesome preparations of bringing them downstairs or getting them out of the place they are kept, troubles which have to be repeated on the return home.

All these troubles are completely avoided by the use of the cot carriage object of this invention, which has the advantage of being foldable, and consequently occupying a small space in this position, at the same time its weight is insignificant, with the fact that it can be easily carried in one hand. Thus there is no difficulty in carrying it upstairs, taking it into lifts, cars,

trams, etc., and it is notable also for the small space it occupies when not in use.

The movement for folding or unfolding is extremely simple and does not require any tool or special skill; its joints are solid and cannot be strained by any mean of efforts and the whole offers a complete security and comfort for the child.

Finally, it is to be noted that the placing of the handle has been provided for in such a position that it does not cause any inconvenience, so that the carriage is capable of being used as a cot in the home.

In order to better understand the object of this specification, there is attached a drawing, in which, as an example only, there is shown a practical case of a cot-carriage made up in ac cordance with this invention.

In the drawing, Fig. 1 shows the carriage in side elevation and in a folded poistion; Fig. 2 shows one of the intermediate positions for opening; Fig. 3 shows it in a position to be pushed along; Fig. 4 is a similar view, but with the handle down for the carriage to be used as a cot;

Figs. 5 and 6 are details of the closing or fixing arrangement; and Fig. 7 shows a detail of the principal articulation of the shears.

This cot carriage is made up essentially by a double framework in the form of a shears, consisting of the stays l and 2 articulated in 3 (see Fig. '7) through the shaft 4 that, forming part of the stay 2 and after passing through the stay I. projects towards the free side and is surrounded by the helicoidal spring 5 working under compression and held by a washer 6, fixed by a flat plate 2|, whose object is to maintain a certain fitting and pressure between both stays. The whole is protected by a small cover 1.

Each of the two pairs of stays l and 2 are connected at their bottom ends with cross bars. Each of these cross bars freely rotatably separates at each end one of the wheels 8.

The stays l on their opposite ends to the wheels 8 are joined in an articulated way to a horizontal frame 9 and in their turn the stays 2 are joined to the said frame, although by means of a set of levers Ill and I0 joinable in the form of a compass. The articulation of the stay 2 with the said levers is carried out by H, such stay being prolonged and having on its end another articulation I2, shown in detail in Figures 5 and 6.

To this articulation there is joined the lower end of the two branches I3 of the handle, which has at the same time another articulation l4 similar to the II of the stay 2, with which it is joined with the said set of levers ID and It).

The horizontal frame 9 has suspended by various helicoidal springs l5 a second cot I6 that holds a net, cloth or something similar, constituting the cot itself.

The handling of this cot-carriage is as follows: Supposing it to be in the position shown in Fig. 1, to open same it is only necessary to separate the handle l3 from the body of the carriage, raising it by the part to be held by the hands, with which movement the articulation of the stays of the said handle 13 with relation to the stays 2 on the axle 12 will cause a progressive separation of the compass formed by the levers Hi and I0 articulated together in l l and I4 respectively, which will continue opening until the axle of these coincides with that of the articulation l2.

This movement Will have resulted in a pr0gres sive opening of the shears formed by the stays l and 2 until they adopt the position shown in Figures 2 and 3.

Once in this position, the last movement of the handle, until it adopts the position of Fig. 4, will not cause any Variation of the shears.

In order to close the carriage, there is only necessary a reverse movement of the handle. This will produce the progressive closing of the shears until they again adopt the position shown in Fig. 1.

To fix the handle 13 in the position desired, the articulation l2 (Figures 5 and 6). are provided with a clasp formed by two discs I! and I8 radially fiuted, forming part of the stays 2 and 19,.

which may remain clutched or unclutched.

through the action of a threaded shaft 19', forming. part of an exterior lever 20.

The Whole may be completed with a folding cover and also provided the arrangement of some rings on the handle $3, in order to fix on same some bags to contain clothing or other things.

I claim:

In a folding carriage for children, in combination a frame; a handle; a pluralit of stays articulated in the form of sets of shears, capable of being closed andopened by movement of said stays, one of the stays of. each. of said sets of shears being articulated to, said frame and the other of the stays of each of said sets of shears being articulated to said handle; and a set of levers pivoted together in the form of a compass and joining said other stays to said frame so that the pivot of said levers coincides with the articulation of said other stays and said handle, in Which position the latter may continue to turn until it is completely depressed.
