14 Claims.

This invention relates to improvements in baby carriages and it consists of the matters hereinafter described and more particularly pointed out in the appended claims.

One of the objects of the present invention is to provide a baby carriage of the so-called coach type, which may be quickly and easily folded when necessary, so as to occupy but minimum space, and may be as readily opened up for purposes of use.

Another object of the invention is to provide a carriage of this kind which includes foldable end frames and a collapsible body, the latter operating when in a position for use, to hold the end frames in their extended position and at the same time be supported in its extended condition by said end frames.

A further object of the invention is to provide a carriage of this kind having a body which by the actuation or release of simple locking means, collapses into its folded condition under gravity actie-n.

Again, it is an object of the invention to provide a novel structural connection between the body top frame and end frames of a carriage of this kind, whereby the body frame has an easy sliding movement with respect to the end frames so that no binding action takes place in folding or extending the carriage.

The above mentioned objects of the invention, as well as others, together with the several advantages thereof, will more fully appear as I proceed with my specification.

In the drawings:

Fig. l is a perspective view of the improved baby carriage when extended or opened into its position of use, certain parts of the body thereof being shown as broken away to more clearly disclose the interior construction.

Fig. 2 is a perspective view of the carriage in its folded or collapsed condition.

Fig. 3 is a longitudinal vertical sectional View through the carriage when extended or opened as shown in Fig. l.

Fig. 4 is a fragmentary view in elevation, on an enlarged scale, of the top portion of the front end of the carriage when in its open or extended position.

Fig. 5 is a fragmentary view in elevation of a side portion of the rear end of the carriage when in its open or extended position.

Fig. 6 is a detail horizontal sectional view through a part of the carriage on a further enlarged scale as taken on* the line 6 6 of Fig. 4.

Fig. 7 is a perspective view of a frame employed in the bottom of the carriage body and upon Which the baby occupant is placed and which frame holds the bottom of the body to shape when the carriage is in its open or extended position.

Referring now in detail to that embodiment of the invention, illustrated in the accompanying drawings, the carriage includes a wheel frame comprising a pair of substantially horizontal, longitudinal frame members III-I0 having upturned front and rear ends Il and I2 respectively. The frame members are held in spaced relation by means of front and rear axles I3 and I4 carrying the usual pairs of Wheels I5 and I6 respectively. As the specific structure whereby the axles are connected to the frame members IE! and II, forms no part of the present invention, the same is not illustrated or described in detail.

I'I indicates the front end frame of a generally inverted U shape and including side members or legs I8-I8 and a top connecting member I9. The bottom end of each side member I8 has a clip strap 20 secured to the outside thereof. Each strap extends a suitable distance beyond the extremity of its associated side member and is pivotally connected to the extremity of an upturned frame member end II by means of a pin 2|. The extremity of each clip strap is bent to form a hook 22 to engage a part of the associated frame end II so as to limit the pivotal or swinging movement of the front end frame in one direction, to a substantially upright extended position as best shown in Figs. 1 and 3. 35

Extending parallel with and along the inside of each member I8 of the frame I1 is a rail 23. The bottom end of each rail is operatively secured in place by the pivot 2l and the top end of each rail is operatively secured in place by a pin 24 passing through the associated side member I8 near the cross member I9. Each rail is held in spaced relation from its associated member I8 by means of washers 23a. disposed upon the respective pins 2 I-24 as best shown in Fig. 4.

From the construction above described, it is apparent that the end frame may be swung from its folded or collapsed position wherein it is disposed substantially horizontal as best shown in Fig. 2, to its unfolded, open or extended, substantially upright position as shown in Fig. 1, and vice versa. It is to be understood, however, that the upright position is determined by the engagement of the hooks 22 of the clip straps,

Cil

with the associated upturned end I I of the wheel frame side members Ill-I5.

indicates the rear end frame also of a generally inverted U shape. It includes side members or legs 26-26 and a top connecting member 21. 'I'he side members 26-26 of said frame are of a length greater than the corresponding members of the front end frame. 'I'he top ends of said side members are curved rearwardly so as to bring the cross member 21, when said rear end frame is in its extended position, into an elevation convenient for use as a push handle. A hand grip 28 may be employed on the cross member for this purpose. The top curved ends of the side members are also spread slightly outwardly so as to permit this frame to fold down upon the front end frame I1 into a more compact folded condition as best shown in Fig. 2.

The bottom end of each side member 26 has a clip strap 29 secured to the outside thereof and which clip strap is similar to the clip strap 20 before mentioned in connection with the front end frame I1. Each clip strap 29 extends a suitable distance beyond the extremity of its associated side member and is pivotally connected to the corresponding end I2 of the member I0 by a pin 3D. The extremity of each clip strap is bent to form a hook 3l to engage a part of the associated end I2 so as to limit the pivotal or swinging movement of the rear end frame, in one direction to a substantially upright extended position as shown in Figs. l and 3. In this so-called upright extended position, the bottom straight ends of the side members do not extend truly perpendicular but lean slightly rearwardly thereof as this gives a better push angle for the frame in pushing the carriage in the conventional manner.

Extending substantially parallel with and along the inside of the straight bottom portion of each member 25 of the rear end frame 25 is a rail 32. The top end of each rail is secured in place with respect to its associated side member 26 by means of a pin 33, a washer 34 on said pin holding this end of the rail in the desired spaced relation with respect to the side member. The bottom end Vof each rail 32 is pivotally connected as at v35 to one end of a link 36 the other end of which is mounted on the pin before mentioned. This link arrangement permits a limited amount of swinging movement of the bottom end of the rails 32 for a purpose to appear later.

40 indicates as a whole, the body of the carriage which includes a body fabric 4I and a rigid top frame comprising the side members 42 and end members 43. The main end members 43 each have end portions 45 bent to engage the side members 42 and secured thereto by rivets or pins 48-41. Parallel with but spaced outwardly from each end member 43, is a channel bar 49 of inverted U shaped cross section. This bar carries end brackets 49a which are pivotally connected to the associated top frame members 42 by the pins 45 before mentioned.

The extremity of each bar 49 is made as a sleeve 50 embracing the rails 23 and 32 so as to have a sliding engagement thereon. In each bar 49 is a pair of spring pressed plungers 5|-5I, the inner ends of which are bent to extend through slots in the top side of said bar and there be provided with knobs 52. The outer end of each plunger slides through a hole in the sleeve to engage in a recess 53 in the top end of the respective rails 23 and 32. The recess 53 appears best in Fig. 4.

The body fabric 4I includes Vside walls 54, bot'- tom wall 55 and end walls 56, suitably secured to gether at the margins. The top margin of the side and end walls are formed to provide pockets 51 and 58 respectively to receive the side bars 42 and end bars 43 of the body top frame and whereby the body fabric is operatively secured as a whole to the top` frame.

The side walls of the body are out to such pattern that when said body is in its open or extended condition, it substantially follows the contour of the wheel frame members I0 and the front end frame and the bottom portion of the rear end frame.

The top frame for the body is of such length that when the carriage is in its unfolded open position, it exerts an outward pressure (forwardly and rearwardly) on the end frames to slightly tension the clip straps 2l! and 29 so that said frames are somewhat tensioned to rigidify the frame structure, as a whole.

Associated with the body is a foldable hood 59 of any approved form that is pivotally connected to the side members of the body top frame, at a point about midway the ends thereof.

The body fabric being flexible, there is provided within the bottom of the body, a frame 6U best shown in perspective in Fig. 7, which not only holds the body bottom to form, but which supports the usual cushioning material for the baby occupant.

The body bottom frame comprises spaced side members 5| preferably of wood, and rigid connecting end and top and bottom bars 62--63 and 64 respectively, there being flexible connecting straps 65 between the end and the bottom center bars. The bottom edges of the side members 6 I are cut on a curve substantially to conform to the cut of the bottom of the fabric body to hold the same to shape.

The top rear end half of the body bottom frame has a sea-t member 65 rigidly secured to one end bar 62 and a part of the top center bar 63. A closure member 61 is provided for the front end half of the body bottom frame and which closure member is removably engaged on the other end` bar 62 and the other part of the top center bar. Both the seat member 66 and associated closure member 61 may be suitably padded and when Yin place upon the frame, provide the support upon which the usual carriage robes and pillows mayv be placed for the baby. The space within the body bottom frame provides a convenient storage compartment for desired articles of use, and which space is accessible by the removal of the closure member 61.

Assume that the carriage is in its extended position and it is desired to fold the same for storage or for transport as in an automobile. The operator grasps the two knobs 52 associated with the bar 49 of the front end frame and moves said knobs toward each other. This retracts the ends of the plungers 5I from the recesses 53 in the rails 23. The gravitation eifect of the front end of the body causes it to slide down the rails 23 to collapse this end of the body fabric 4I after which the front end frame I1 is swung inwardly and downwardly upon the front end of the body top frame. In this downward movement of the end frames I1, the bar 49 pivots about the pins 46, and forces the associated end of the body downwardly into a more compact folded condition.

The knobs 50 associated with the rear end frame are then grasped and moved toward each other `and this retracts the plunger rods 5I from the recesses 53 in the rails 32 so that the gravitation effect causes the rear end of the body to slide downwardly on said rails to collapse the rear end of the body fabric after which the rear end frame 25 is swung inward and downward upon the folded down front end frame I1. In this downward movement of the body, its bottom rst comes to rest upon the axles I3 and I4, the side walls and end walls folding into pleats as best appears in Fig. 2. Due to the inclination of the end frame 25, as the rear end of the body slides down the rails 26, the bottom ends of the rails 32 swing rearwardly, the link connection before mentioned, for the bottom ends of said rails, permitting this movement so that no binding action can cramp the downward folding action of the rear end of the body. As the rear frame swings downwardly, it operates through the associated bar 49 to force this end of the body into a more compact folded condition.

To open up or extend the carriage into a position of use, the rear frame 25 is rst swung upwardly into its substantially upright position and then the front end frame may be swung upwardly into its substantially upright position. An upward lift on rst one bar 49 and then the other, will cause the body to be opened up or extended, the plungers 5I of said end bars snapping into the recesses in the top end of the rails 23-32. The top frame of the body is of such length as to force the end frames slightly outwardly so that the associated clip straps are somewhat tensioned to have a tight engagement with the ends II and I2 of the side members of the wheel frame. Thus the body top frame holds the end frames in the upright extended condition and in turn is supported in an extended condition by said end frames. This provides a structure which in its extended position is extremely strong and rigid.

While in describing the invention, I have referred in detail to the form, arrangement and construction of the various parts thereof, the same is to be considered only in the illustrative sense so that I do not wish to be limited thereto except as may be specifically set forth in the appended claims.
