16 Claims.

This invention relates to improvements in perambulators, baby carriages, and the like, and has as one of its principal objects the provision of the folding type of carriage with a carriage well or cradle of flexible or foldable material and having a rigid end wall or dashboard for the cradle, and

mechanism for folding the end wall inwardly when the carriage structure is'collapsed.

Viewed from another aspect, it is an object of IO the invention to provide a folding carriage including a collapsible frame with a fabric carriage well or cradle mounted on the frame, the cradle being preferably, though not necessarily, provided with a relatively rigid bottom wall portion, and the car-'- riage being provided with arigid end wall member for the cradle, and lever means cooperable with the carriage frame for folding the end wall automatically into reclining position against the re mainder of the carriage well structure when the 20 carriage is collapsed. e

Other objects and advantages of the invention reside in certain details of'construction and operation of the carriage frame, folding cradle structure, and cooperating lever means, all of which 25 will be particularly specified as the following description proceeds in view of the annexed drawings, in which:

Fig. 1 is a perspective view of a preferred embodiment of the novel carriage structure;

30 Fig. 2 is a fragmentary side elevation;

Fig. 3 is a side elevation showing the carriage collapsed;

Fig. 4 is an enlarged fragmentary top plan view of the collapsed end wall;

35 Figs. 5, 6, and 7 are views respectively similar to Figs. 2, 3, and 4 except that the former include the modified footwell mechanism of Figs. 8 and 9;

Fig. 8 is an enlarged side elevation of a modified footwell attaching and operating mechanism;

40 while Fig. 9 is a perspective detail of the modified footwell mechanism in raised condition.

For purposes of illustration, we have chosen the type of folding carriage described and claimed in 45 our U. S. Patent 2,111,974 for a Carriage, it being understood, however, that the invention herein may be applied to other forms of collapsible or folding carriage, as will be more fully pointed out hereinafter.

50 In the illustrative carriage structure of Fig. 1, there is provided a wheel chassis including wheel bearing axles l mounted on cross bearers H to provide a relatively rigid wheel base.

A collapsible frame structure, including two pairs of scissors or cross arms l2 and I2, is

ties of thescissor arms. Each pair of the so- 5 called'scissors or'cross arms is pivotallyj'oined as at fit between the respective ends of" the arms, there being a cross bracket l9 extended from the pivoted connection to give added rigidity to the structure; g

The upper ends of the-maincross arms l2 are pivotally attached as at 2i) to horizontal rail's 2|, while" the companion arms T2 of each pair are pivotally connected as atZ'ZZ (Fig. 2 also) to the lower ends of pivot' arms 23' arranged on opposite sides of the carriage top rails 21' andpivotally attached as at 24betwe'en' their ends to these horizcntal top rails 21. The upper ends of the pivot arms 23 are respectively'connected'to the free end portions of: a handle structure 25.

By manipulation of the handle about the connecting points 24 as an axis, the carriage frame may be collapsed or' raised relative to the chassis; When the handle is pushed toward the left (Fig; l) the leverages are such that the frame 25 members tend to'pivotiinto'thecollapsed condition illustrated in Fig; 3 and" vice 'versa.

In order to prevent accidental" collapsing of the carriage when the, sameis in use, there is provided a detentmeans 26' on the main frame arms [2" 0 adjacent the pivotal connections 22" and so arranged as to effect automatic latching engage ment' between the pivot" arms 23 and the main frame arms l2 (not illustrated in detail to prevent'relative pivotalm'ovem'ent of the frame parts for the purpose aforesaid. If desired, the pin and slot arrangement of" our aforesaid patent may be employe'd'in place of the detent means 26.

A fol'dabl'e' carriage well'or cradle 30, made from canvas or any other suitable and analogous mate- 40 rial, and of s'ubstantially rectangular form, is swung from the top rails 21 by any usual means, there" being a trimmihgrail 3 l secured on the top rails 2 l" to dress the attachment ofthe cradle to the frame a'nd also provide a suitable contact surface for the carriage occupant. Thecarriage well or cradle fabricf is attached to the horizontal frame rails only" along oneend wall and partially through the length of'the adjoining side walls, the points of attachment corresponding to the length 66 of the trimming rail3 l*, so that the top horiz ontal' edges of the cradleat one end are left" free for movementin a substantially verticalsenseirelative to thetop rails H, the purpose of this beihg" to permitfree'doiiror movement so that thisportion' of the cradle may be lowered into the position seen in Fig. 1 to provide a footwell, the carriage thus being convertible into a stroller.

One of the important features of the invention is the provision in the footwell portion of the cradle of a relatively rigid end wall or dashboard to which the vertical and horizontal bottom edge portions of the cradle fabric are securely attached by any suitable means.

Means attaching the rigid end wall to the carriage frame for cooperative folding movement with the latter includes a pair of lever arms 36, each of which is pivotally attached as at 3'! to one upper corner part of the rigid end wall member 35 as by means of brackets 38, the opposite ends of the levers 36 being pivotally attached to the top rails 2| by pin means 39 (Figs. 2 and 3) horizontally slidable in slots 40 formed in the rails 2 I.

Each of the lever arms 36 is provided with a headed seating pin 4| spaced inwardly from the mounting pins 39 and adapted to seat in notches 42 formed near the upper edge extremities of the rails 2|.

When the carriage is in use as a stroller, as illustrated in Fig. 1, the footwell may be raised by grasping the end wall 35 and moving the same toward the right, the pins 39 sliding in the slots 40 so as to dispose the seating pins 4| in advance of the extremities of the top rails 2| to clear the latter, whereupon the end wall 35 may be pushed slightly to the left so that the pins 4| will fall into the notches 42in which condition the carriage will appear as in Fig. 2.

The end wall member or dash 35 may be constructed of wood or analogous material and is preferably provided with a utility pocket in the form of a door 45 attached by hinge means 46 to the end wall member and movable from a normally latched position in a recess in the end wall or dash member into the dotted-line position illustrated in Fig. 2. Preferably the inner side of the end wall 35 is provided with the cushion means 41 indicated in Figs. 2 and 3, the bottom of the carriage well or cradle likewise being provided with a relatively inflexible cushion means 48, which, while soft enough to provide adequate comfort for the carriage occupant, nevertheless lends some rigidity to the bottom of the carriage well. This latter feature, while not essential, and apart from any considerations of comfort, tends to render the collapsing operation of the carriage cradle consistently uniform.

The lever means 36 is so arranged and constructed with relation to its form and attachment to the end wall member 35 and folding frame structure |22|, etc., that the collapsing and erecting movements of the carriage frame effect corresponding movements of the end wall or dash, with the result that when the carriage is collapsed by release of the detent means 26 and movement of the handle 25 (toward the left) and the carriage frame folds into the condition viewed in Fig. 3, the novel end wall 35 will pivot with positive movement into reclining position, neatly folded back against the cradle as it rests on the chassis as illustrated in Fig. 3.

In this latter operation, the descending movement of the top rails 2| when the carriage is collapsed from the condition seen in Fig. 2 ultimately effects a counterclockwise movement of the lever arms 36 about their pivotal connections 39 with a consequent tilting of the end wall 35 toward the left and into collapsed condition on top of the folded cradle. When the carriage is erected, the reverse operation occurs and the end wall or dash is automatically raised into erect position and will generally be latched by the pin and notch means 4|42 without further attention, it being occasionally necessary, however, to grasp the member 35 and give it a slight push toward the right to effect seating of the pins 4|.

The employment of a relatively rigid end wall or dash 35 results in a much more satisfactory footwell structure, not only from the standpoint of automatic positioning of the footwell in lowered condition (so that the otherwise flexible cradle fabric will positively assume an appropriate shape and position), but also from the standpoint of comfort to the occupant, a rigid support having obvious advantages over the relatively unstable support afforded by the ordinary cradle bag when the latter is lowered as a footwell. In addition, the appearance of the carriage is greatly improved and the utilitarian feature of the pocket or shelf means 45 is further made possible.

In place of the footwell mechanism 36-39 4|l4|42 of Fig. 1, we may employ the arrangement particularly shown in Figs. 8 and 9, Wherein the rail 2| is pivotally attached as at 50 to the link 23', and the link 36, instead of being attached to an extension of the top rail, is pivotally connected by pin means 5| working in a horizontal slot 52 in a curved arm 53, which is secured by the pivot pin 50 and a rivet 54 to the link 23'.

The links 36 are mounted on the inner sides of their respective arms 53 at opposite sides of the carriage. Each link 36' has a notch 42' near its free end and into which the pin means 4| on the link fits when the footwell is raised, as exemplifled in Figs. 5 and 9. The outer ends of the links 36 are pivotally connected to the footwell as at 31', similarly to the arrangement of Fig. 1.

Means for limiting the movement of the footwell relative to the link 36 includes a U-shaped stop 55 pivotally attached at the juncture of the link with the arm 53 by the pivot pin 5|. The stop 55 permits pivotal movement of the link 36 only limited amounts in opposite directions.

In operation, the footwell linkage shown in Figs, 5 through 9, works much the same as the arrangement of Fig. l, but, whereas in the arrangement of Fig. 1 the footwell is positively folded back as a result of its contact with already folded and underlying portions of the cradle as the latter are bedded down onto the chassis when the handle 25 is lowered, in the arrangement of Fig. 6, the arm 53 begins to pivot positively in an anticlockwise direction (clockwise in Fig. 8) as soon as the handle 25 begins its lowering movement, with the result that the footwell likewise begins its folding movement at the same time, the link 55 assisting when the footwell is in raised position.

While the foregoing illustration of the invention has been specific with respect to certain details of construction and operation and while we have illustrated our invention in conjunction with a particular type of folding frame structure, it will be understood that various changes in form, location, and operation of the specifically described parts may be made without departing from the broad spirit of the disclosure and improvement, it being contemplated that the invention may be utilized with any form of collapsible carriage frame which includes a chassis or its equivalent and supports including top rail members or their equivalent arranged to be folded down onto the chassis'the novel end wall structure having connection by means equivalent to the means 36, 31, 38, 39, 4!], 4|, 42, etc., to the carriage well frame, substantially in the manner and for the purpose set forth and as broadly defined in the claims appended hereto.
