4 Claims. (01. 28041) This invention relates to a combination baby stroller and high chair whichmay be quickly folded with one hand into'a compact package which may be carried like a hand bag.

Another object of the invention is to provide a combination stroller and chair which folds into a substantially square package.

Another object of the invention is to provide a combination stroller and chair which may be folded outward and downward instead of in common scissor manner.

Another object of the invention is to provide a combined go-cart and chair which may be quickly folded with one hand, and which automatically locks itself in such folded position, the lock being manually thrown open.

A further object of the invention is to provide a go-cart which may be folded to form a stool for an adult.

A still further object of the invention is to provide a foldable go-cart of standard formation when opened up for use, in order that it may be equipped with the conventional back drop and adjustable foot rest for a sleeping child.

With the above and such other objects in view as may hereinafter more fully appear, I have invented the device shown in the accompanying drawings in which:

The herein described invention was designed fora general utility go-cartor stroller soconstructed that it may be set up or folded with one hand by a person holding a child, and therefore not having the use of the other hand, and which when folded, automatically locks itself into a compact, relatively small package, which requires little room in crowded and close quarters such as stores, busses, cars etc. and for storage purposes. Also when folded it may readily be carried as a hand bag and which also provides a stool upon which an adult may sit.

In the accompanying drawings I indicates my improved stroller or go-cart which comprises a seat 2, a back 3, a handle 4,

legs

5, 6, 1 and 8, a foot rest 9, and wheel H], H, l2, and I3, and side arms I4 and I5. I

The seat 2 is supported upon side frame members l6 and I! to which the front legs Sand 1 are rigidlyfixed and connected by brace members. l8 and I9. A cross brace 20 also connects the said side frame members.

The back of the chair or seat consists of a pair of side uprights 2| connected by a cross bar 22 spaced somewhat above the

lower terminals

23 and 24 of said uprights; These terminals are connected by a cross pivot bar 25, which have swingingly mounted thereon a pair of spaced

apart release bars

26 and 21, the purpose of which will presently be explained. s i

The ends of the bar 25 are fixedly carried in the rear ends 28 of the frame members l6 and H,

and between which ends and said

terminals

23 and 24 swing metal straps 2'9 and 30, as best seenin Figure 4, which are fixed to the upper'ends 3| and 32 of the

rear legs

6 and 8, thus providing pivotal movement of said legs.

Adjacent the lower ends of the

rear legs

6 and 8, an axle member 33 is carried and onv the outer ends of which the rear Wheels l2 and" I3 are mounted.

A. look release bar 34 is slidably supported in the

longitudinal slots

35 and 36 of the frame members I6 and l! and has its end 31 bent at right angles to form a hand crank for manipu lating this bar, upon which is mounted a pair of spaced apart leaves or '

flange members

38 and 39 against which the

fingers

40 and 4|, fixed to the free ends of the

members

26 and 21 normally seat. The extreme ends of said last members bearing against the bar 34 to hold the same against slidable movement and thus hold the go-V cart in locked position.

Pivotally mounted on the outer ends of member 34; are the lower ends of brace link 44 and the links 56-and 51 have their outcr ends pivotedto the legs I and 8 respectively.

Chair arms

58 and 59 are carried by the

brace members

44 and 45.

A handle member 60 has its side bars 6| and 62 pivotally mounted upon straps63 and 64, re-' spectively, projecting outwardly from the upper ends of elements 2 i.

Pivotally attached to members 6| and 62 are

latches

65 and 66 having arcuate terminals adapted to slide over the

catch elements

61 and 68 projecting from the upper edge of the back wall 69, automatically locking the member 60 in operative position upon'being raised. A cord or cable H1 is passed through eyes 42' and has its lower ends secured to the

elements

65 and 66 in order that both latches may be simultaneously raised by drawingupon the central portion of member '10.

Mounted upon the free ends of

bars

26 and 21 are leaf springs Hand 12, (see Figures 5, 6 and 9) which, when'the go-ca'rt is in operative position, bear against the cross brace 20 to retain the

bars

26 and 21 in engagement with the

leaves

38 and 39, respectively, to maintain the go-cart in a set-up position. However, when the said rod 34 is rotated by its crank handle 31 the

leaves

38 and 39 thereon will be disengaged from said

bars

26 and 21 allowing the rod 34 and

brace members

44 and 45 to slide rearwardly with the rod 34 moving in the

slots

35 and 36, of said side frame elements I6. and 1], respectively. This action causes said members 44 land 45 to push down upon thelinks 48 and .49 depressing the inner ends of the links 54. and 55, and 56' and 51, thus drawing in the inclined

rear legs

6 and 8 toward the fixed legs and 1.. Before this action has taken place, the handle member 60, together with the cable 19,.has been gripped by the user which action raises-the latche 65 and I 66 which permits the handle member 4 to swing down against the rear of 1 the: backf69, when the handlememberwill .be automatically caught and held in fastened position'by a spring catch 'l4,carriedbymember22.' 1 7 l The axle member 33,'carried,by.the rear legs, is of sufiiciently greater'length than the front axle 15 as to permit therearz'wheels l2 "and I3 to overlap the frontwheels l0.and..l i when the 4 adult because of the compact, sturdy arrangement of the device when folded. Attached to the rung 85 of the arm 58, which rung, when the device is folded, assumes a horizontal position, is one end of a strap 86, having a snap 81 for engagement with a link 88 carried by the opposite rung 89. This strap is adapted to hold a child in the cart and also forms a handle for carrying the device when folded.

When the device is in its folded position, as shown in Figure 11 of the drawings it is only necessary to turn crank 31 to the right for releasing

leaves

38 and 39 whereupon the locking

bar

26 and 21 can be disengaged from rod 34 for releasing the mechanism and permitting the raisingof the back of the device which action permits the said-lock bars to again function and lock'the parts in rigid operation as a go-cart. The handle member, when raised automatically locks to that position.
