'10 Claims.

The present invention relates to baby carriages and particularly to a carriage of the collapsible type, which, by folding of the carriage body and supporting frame, may be stored in a small space.

In priordevices of this character, it has been desirable to provide for a slight resiliency in the supporting structure, so that the carriage body may be resiliently supported. Where resiliency has been obtained in the supporting structure,

there has invariably been a sacrifice in the stability of the carriage or a sacrifice in the compact foldability thereof. The principal object of the present invention is to provide a supporting structure and carriage body capable of collapsing to a relatively small dimension and 50 arranged that the carriage body may be somewhat resiliently supported Without sacrificing any steadiness of the carriage.

A further feature of the invention resides in the mounting of a brake structure so that it will not interfere in any way with the compact collapsing of the carriage, but which may be readily engaged or disengaged as desired. The invention also contemplates a more secure suspension of the carriage body from the supporting frame for greater stability.

Other and further objects and advantages of the invention will more fully appear from the following detailed description taken in connection with the accompanying drawings, in which- Fig. 1 is a side elevation of the carriage embodying the invention.

Fig. 2 is a fragmentary side elevation on a larger scale of one of the latches which holds the.

carriage in extended position, looking in the direction of the arrow 2.

Fig. 3 is a sectional view through the latch along the line 3-3 of Fig. 1.

Fig. 4 is a view of a part of the under carriage looking in the direction of the arrow 4-4 of Fig. 1.

Fig. 5 is a fragmentary view looking in the direction of the arrow 5 of Fig. 1.

Fig. 6 is a plan View of the carriage.

Fig. 7 is aside view of the brake structure.

With reference first to Fig. 6, the carriage body has a supporting frame comprising a pair of spaced side elements l extending the length of the body and to which is pivotally mounted a U-shaped end element 2. The ends of the latter are pivoted to the elements I between the ends thereof by suitable pins 2a. The side Walls 3 of the carriage body are of a flexible material and are Suspended from the elements I and 2. The

carriage body has a bottom wall d to which the lower edges of the side walls are connected.-

The carriage body is mounted on a supporting frame which is arranged to be extended to permit use of the carriage, as in Fig. 1, or to be collapsed, so that the carriage will occupy very little space when notin use. Referring to Fig. 1, the supporting frame embodies front and rear axles 5 and 6 on the opposite ends of each of which are positioned wheels 1. Reaches 8 extend between the front and rear axles to maintain a suitable spacing therebetween, and these reaches are connected to the axles by clips 9. The reaches 8 are somewhat resilient for a purpose which will hereinafter appear.

The supporting frame on each side of the carriage body is identical, and only the structure visible in Fig. 1 willbe described. Forwardly of the front axle 5 and rearwardly of the rear axle it each reach 8 has depending lugs It and HM rigidly attached thereto. To the lower end of forward lug I0 is pivotally connected, as by a pin H, a link l2, and the free end of the link l2 is connected to the lower end of one arm 53 of the pair of side arms [3 and M by which the carriage body is supported. A similar pair of side arms is located on the opposite side of the body. A link 12g on the lug Ida. has its opposite end connected to the other side arm 3. The side arms l3 and i4 cross each other and are pivotally connected substantially centrally thereof by a pivot pin l5. The arm It extending upwardly from adjaoent the rear axle is pivotally connected at the top end to the side element i of the frame by a pin Ma. The other side arm it has its upper end pivotally connected as by a pin Eta to the lower end of the handle element !6.

Since the reaches 8 are resilient, as above stated, and since the supporting frames for the carriage body are mounted on the reaches at points spaced from the axles, it is obvious that the reaches will spring under the weight of the carriage body. In this way irregularities in the surface over which the carriage is wheeled are not communicated to the carriage body, but are absorbed by the resiliency of the reaches. It will be further noted that the link I2 extends rear- Wardly beneath the axle 5 and the reach 12a extends forwardly beneath the axle 6. Thus, as the links are rocked about the pivot pins by which they are connected to the lugs Ed and Illa on the reaches, they may engage the axles and limit undesirable endwise rocking of the carriage.

The handle element 16, as shown in Fig. 6, is substantially U-shaped and the depending arms thereof are pivotally connected by pins Ita to the ends of the side elements I, the pins Ifia engaging the handle element above the extreme lower ends thereof. The lower ends of the depending arms of the handle element are connected by the pins I3a of the opposite side arms l3 at points spaced from the pins 16a. A latch [8 holds the portion of the handle element on each side of the carriage body in alinement with the side arm I3, as shown in Fig. 1.

With reference to Fig. 3, the latch, also shown in Fig. 2, is U-shaped in cross section with the arms of the U long enough to extend over and engage with the lower end of the handle element and also the side arm I3 pivotally connected thereto where the element and arm overlap. The latch is rockable on the same pin [3a that holds the side arm to the depending end of the handle. A spring 20 surrounding the pin I30. holds the latch against the face of the handle element and in the operative position of Fig, 2. The upper end or handle portion l8a of the latch is offset from the depending end of the handle, as shown in Fig. 2, so that the latch may be disengaged by an inward pressure on the upper end of the latch.

For more stability in the carriage, the pairs of side arms l3 and [4 on opposite sides of the carriage are connected together below the carriage bottom by a connecting rod 2!, Fig. 4, the opposite ends of which are bent downwardly and secured to the side arms by the opposite pivot pins I5. Between the ends of this connecting rod is a depending lug 22 to which are pivoted, by a pin 23, the upper ends of downwardly diverging arms 24 and 24a connected at their lower ends to the short links I2 to which the side arms l3. are connected, the same pivot pin serving for both arms [3 and 24.

For a more rigid support of the carriage body.

' riage is folded, the bottom of the carriage body may move toward the side elements I thereof, but upon opening of the carriage for use, these links 21, 28 and 29 will support the carriage bottom very securely. The pivoted link 28 projects beyond the upwardly extending lug on the bar 26 and engages with said bar to prevent the links 28 and 29 from straightening beyond the position shown, and thereby preventing collapse of the carriage.

The brake mechanism consists of a transverse bar 33 having depending portions 33a which are pivoted to lugs 3! on the reaches. The depending portions of the bar have laterally extending ends 301) in a position to engage with the rear wheels of the vehicle when the central portion of the bar is moved forwardly. The bar 30 has pivoted thereto a rearwardly extending arm 32 having a laterally extending end portion 33 which is in a position to be engaged by the foot of a person standing in back of the carriage. To the arm 32 is pivoted an arm 34 which is also pivoted on the rear axle 5. The arm 32 is curved as shown in Fig. 1, so that when the rearward end thereof is depressed, the pivot point of the arm on each side of the carriage body, the upper ends of said arms being adapted to be connected to the carriage body, and rigid links connecting the lower ends of the arms of each pair to one of the reaches at points spaced from the axles, said reaches being resilient so that the carriage body is resiliently mounted.
