6 Claims.

The present invention relates to baby carriages, and particularly to a carriage of the folding type, which is adapted to provide a resilient support for the carriage body.

In prior devices of this character, the extensible structure by which the carriage is collapsed or extended for use, has been connected to the axles by a resilient supporting structure in order that the body may be resiliently supported. Such an arrangement is entirely satisfactory, but involves the interposition of carrying elements for the axle and the springs for obtaining the resilient connection between the axle and the extensible structure. The principal object of the present invention is to avoid the above objections by incorporating the resilient structure as a part of the extensible elementsby which the carriage may be collapsed.

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 a carriage embodying the invention.

Fig. 2 is a side elevation of the carriage when collapsed.

Fig. 3 is a sectional view, substantially along the line 3-3 of Fig. 1.

Fig. 4 is a side elevation on a somewhat larger scale than Fig. 1, of the latch.

Fig. 5 is a side elevation on a somewhat larger scale, of the brake mechanism.

Fig. 6 is a plan view of the carriage.

Fig. 7 is a fragmentary side elevation on a larger scale of the resilient connection between the running gear and the carriage body.

With reference first to Fig. 6, the carriage body has a. substantially rectangular frame I, from which are suspended the side walls 2 and bottom wall 3, forming part of the body. The side walls are of a flexible material, to permit collapsing of the body when the carriage is folded, as shown in Fig. 2.

The body is mounted on a supporting frame which is arranged to be extended to permit use of the carriage, as in Fig. 1, or collapsed, as in Fig. 2, so that the carriage will occupy very little space when not in use. As best shown in Fig. 1, the supporting frame embodies front and

rear axles

4 and 5, on the opposite ends of which are positioned wheels 6. Integrally connected to the rear axle is a, U-shaped element I. having upwardly extending arms 8, one of which is positioned on each side of the body. A similarly shaped element 9 is positively connected to the front axle, and has upwardly extending arms Ill positioned on opposite sides of the carriage body.

As shown in Fig. 1, the upper end of each arm 8 is connected by a coil spring II to the frame I, and is also supported in predetermined relation to the frame I by a link I2, pivotally connected at its upper end to the frame, as by a pin I2, and at its lower end to the arm 8'by a pin 8 a short distance below the upper end of the arm. A projecting lug I3 on the link 12, limits the relative movement between these parts by engagement with the side of the arm 8.

The arms 8 and HI, on opposite sides of the carriage, are pivotally connected at their intersection by a pin 14, and the upper end of each arm H3 is pivoted by a pin I5, see also Fig. l, to the lower end of one arm It. The handle ll, which, as shown in Fig. 6, is substantially U- shaped, and has the arms i6 extending downwardly on'opposite sides of the carriage body.

Each arm of the handle is pivoted at it to the frame I, this pivotal point it? being above the pivot pin I5.

To hold the supporting frame in extended position, the arms I0 and handle It are held against relative movement, when extended, by a latch, best shown in Fig. 4. With reference to this figure, the arm I5 of the handle extends downwardlybelow the pivot pin I5, and has a notch 19 engageable with a pin 23 on the arm H1. The arm IE or the handle has pivoted thereto on a lug ZI, a latch member 22, which has a notch 23 in the lower end thereof in a position to engage the pin 28. The notches I 9 and 23 are out of line with each other, as shown, so that when the pin engages the bases of the notches, the pin cannot be released without a turning movement of the latch member 22 clockwise. The latch member is normally held in the pin-engaging position shown, by a coil spring 24. Obviously, the pivot pin 25 which supports the latch 22 is spaced from a line connecting the notch I9 and the pin l5 so that the notches i9 and 23 will be out of alinement.

With reference to Fig. 5, the pivot pin it which connects the arms 8 and 16, also has mounted thereon a brake arm 26, having an upwardly extending handle 2'1. Pivoted to the brake arm on a pin 28 adjacent to the pivot pin 14, is a brake bar 29, having a slot at engageable over a pin 3| on the arm 5. At the lower endof the bar is a laterally extending element 32 in a position for engagement with the periphery of one of the wheels 6. As will be apparent from Fig. 5, when the brake arm is rocked forwardly from the position shown, the brake bar is moved downwardly to engage the wheel, and the brake is locked in braking position by the toggle effect of the connection between the brake arm and the bar. The brake arm has a laterally extending projection 33 on the end thereof, which engages with the side of the bar to retain the elements in Ibraking position, the engagement between the bar and projection 33 being effective after the pivot pin 28 is slightly above a line connecting the element 32 and the pivot pin M In collapsing the extensible structure from the extended position of Fig. 1, the upper ends of the latch members 22, which have laterally extending lugs 22', are pushed. forwardly to disengage the notch 23 from the pin 20. The handle ll may then be rocked forwardly about the axis of the pin 18, thereby allowing the arms 8 and Hi to move relative to each other substantially into the position of Fig. 2. The arm 8 pivots relative to the link [2, and the link, as shown, may pivot slightly as the carriage collapses. From the collapsed position of Fig. 2, the carriage may be extended for use by an upward and backward movement of the handle IT, as will be apparent. As the carriage reaches extended position the pin 29 engages with the face of the latch member 22 and causes it to swing clockwise to allow the pin to enter the notch IS. The coil spring 24 then returns the latch member 22 to locking position. As the brake structure is supported entirely on the arm 8 it will be obvious that the collapsing of the carriage will have no effect thereon.

When the carriage is extended for use it will be apparent that the coil springs H act as a cushioning means for the carriage, since, as weight is applied to the carriage, the upper ends of the arms 3 and I0 tend to move away from each other so that the arm 8 moves relative to the carriage body through the interconnection of the coil spring II and link I2. The carriage body is thus resiliently supported on the frame. f
