9 Claims.

The specification which follows relates to certain improvements in folding perambulators or baby carriages. It is a further development of the .carriage disclosed in my prior United States patent granted March 13, 1951, No, 2,545,069.

The earlier structure dealt with rigid side frames capable of being laterally separated to -provide a seat, back and foot-rest, with an appropriate handle for pushing and guiding the vehicle.

The `present invention is directed to further improvements .and developments in the seat and foot-rest as well as minor structural details.

It is an object of my invention to provide for conjoint operation of the seat and foot-rest.

It is a further object of my invention to provide an improved handle means for collapsing the seat and foot-rest :and carrying the vehicle in folded condition.

Among the objects of my invention is the provision of adequate support from below of the seat in its operating position.

A Istill 'further object of my invention is the provision of improved mounting for the footrest.

An object of the invention is also the provision of fastening the seat cushion and locking 'the fastening means against disengagement.

More particularly, the invention contemplates the assembly of a childs folda-ble lperambulator comprising a pair of rigid side frames having stub shafts and wheels thereon, each side frame having front and rear spaced vertical channel members, the members having inner side flanges and outer side flanges with inturned edges, a pair of cross-bars pivoted at their lower ends to the inner flanges of each side member and having studs at their upper ends slidably confined within the inturned edges of the outer flanges in the opposite channel members, a seat h'aving its side edges pivotally held at each side on the inner flanges of the channel members and having acentral longitudinal hinge, a footrest pivotally held at its sides on the outer flanges oi' the channel members, said foot-rest having a central longitudinal hinge and a link connecting the front of the seat hinge with the rear yof the hinge of the foot-rest.

On the accompanying drawings I have shown the invention in its several details o'f construction.

In the drawings Fig. 1 is a side elevation of the improved perambulator opened for use;

Fig. 2 is a front elevation of the same;

` a D-handle 22 2 Fig. 3 is a rear elevation; Fig. Li is a bottom View; Fig. 5 is a perspective view of the perambulator partially collapsed;

Fig. 6 is a fragmentary detail view in perspective of a channel member and the pivoted cross-bar;

Fig. 7 is a like View of the channel member and the upper end of the cross-bar and Fig. 8 is a fragmentary detail view in perspective of the mode of fastening the rods for holding the edges of the vseat cushion.

By way of example, and as illustrating the preferred form of my invention, I have shown on the drawings a folding perambulator or baby carriage built up from two side frames Il, constructed of rigid metal parts. These side frames can :be drawn together into a compact arrange- "ment, such as is shown in my earlier patent above referred to.

Each frame has a lower horizontal bar l2, the forward end of which has an extension i3. These bars l2 each have two stub shafts I4 on which wheels l5 are mounted.

The side frames also include two vertical channel members Iii, rigidily riveted or otherwisey attached to the lower horizontal bars. The channel members are connected at the top by arm rests I1, also rigidly attached. The frames therefor form parallelograms. Diagonal guide members I8 extend from the front of the horizontal bars i2 t-o the top of the rear channel member it. These guide members yare channeled, and receive flexible metallic arms I9.

Each arm I9 carries a tooth 2i) at the lower end, which strikes a rigid collar 2l clamped across the upper -end of the member i6 to limit the backward extension of the arms.

The rear ends of the arms are connected by This provides a spacing between the arms i9 when the frame is collapsed. In this way, the handle when brought down lserve-s with the -arms to prevent undesired opening of the structure.

Each channel member I6 has an inner straight ange 23, yand an outer flange 24. The outer flange has an inturned edge 25 which is cut away at the bottom, as shown at 2t, for facilitating assembly.

The Irigid side frames are held in parallelism by means of two pairs o'f cross-bars 2l, 28. One pair of cross-bars connects the front channel members i6, while the other pair of cross-bars 28 connects lthe rear pair of channel mem.- bers I6.

Each pair of cross-bars has its lower ends riveted, as shown at 29', to the inner straight flange 23 of the channel member I6. These form pivots controlling the movement of the

cross-bars

21, 28. Each pair of cross-bars is pivoted together at the mid-point by means of rivets 29 or the like.

At the top, each cross-bar carries a stud 3B. This stud slides vertically in the channel member and is confined within the channel by means of the inside inturned edge 25. This is clearly shown in Fig. 7.

I have provided a hinged seat made of two rigid metal portions 3|, 3|. These have a center hinge 32 established by riveting the portions 3| together at the front and rear. The opposite sides of the portions 3| are riveted to the inner flanges 23 of the channel members i6. In each instance, the riveting permits the parts to have pivotal movement.

A foot-rest 33 is also provided of two

metallic portions

34, 34. These also are riveted together at front and rear along the center line to permit movement as a hinge.

The front portions i3 of the horizontal bars vI2 are provided with

vertical extensions

35, 35. These are rigidly attached to the bars. Pivot rods 36 extend horizontally between the vertical extensions 35, and the outer flanges of the forward channel members I5. These pivot rods carry the

portions

34, 34 and permit the latter to take a horizontal position mutually braced at the center hinge and supported at the outer sides. A link 3'! extends downwardly from the front of the center hinge 32 of the seat. This link is offset, so that it is in front of the forward pair of Cross-bars 2l. The lower end of the link 31 is slotted, as shown at 38. The rear pivoting rivet of the foot-rest passes through this slot, so that the link may rest upon the pivot when the foot-rest is horizontal, or may allow a certain degree of relative movement when the structure is collapsed or folded.

A link 39 is riveted to the hinge at the rear of the seat, as shown in Fig. 3. This link has a long slot 4H which receives the pivot of the rear pair of cross-bars 28. Here again, the seat and cross-bars are capable of relative movement. However, the seat, when horizontal, rests upon the link 39 which in turn is supported by the lpivot of the cross-bar.

A cushion 4| of lled fabric is provided to rest upon the side portions 3|. This cushion is held down by means of two rods d2, 42. These rods extend substantially horizontally between the channel members i6. The front end of each rod 42 is provided with a key 43 which can be inserted through a slot M in the inner flange 23. A quarter-turn of the rod then locks it from accidental removal. The rear end of the rod 42 has an eyelet 45 which is horizontal when the key is locked. Y

The rods l2 are threaded through Ythe sides of the cushion 4| in assembly.

The rods are prevented from disengagement by means of vertical rods t5. These run vertically behind the rear channel members l5. At the bottom, they pass through eyelets t5, and at the top they are riveted to the arm rests. These rods t6 are threaded through the sides of a back cushion 4l.

Slotted plates 48, 4|] are also part of the pivot at the front and rear of the center hinge 32 of the seat. A strip of webbing lle extends loosely between the slotted plates. This forms means for holding the cushion down at the center when the seat is spread out. Also, when the carriage is folded, the strip is brought up into the same plane with the arm rests I1. As the arm rests are spaced apart, they do not form a satisfactory carrying grip or handle. However, the intermediate strip 49 can be used as a handle. It will also apply the lifting force to the center of the lseat both in the folding operation and in carrying. This prevents the seat from opening up when not desired.

In the arrangement set out, the structure in the prior patent has been altered to provide manifested advantages and improvements. The rigid side frames when separated or extended bring the seat portions into a horizontal plane and distend the seat cushion. At the same time, the foot-rest is spread out and connected by a link to the seat portions. Likewise, the rear pair of cross members are connected to the seat portions in such a way as to form a positive central support.

To fold or collapse the device it is only necessary to draw up on the webbing 39. This causes the seat portions to fold, and at the same time folds the foot-rest.

The seat cushion is locked into place by the same means which supports the back cushion.

lThere results a convenient and compact vehicle which is rugged and easy to manufacture.

While I have described the preferred form of the invention and illustrated it on the accompanying drawings, it will be apparent that numerous changes in proportions, materials and structural details may be carried out without departing from the scope of the invention as defined in the following claims.
