This invention relates to a frame for baby carriage.

An object of the inventionis to provide a structure in which the front part of the frame portion which supports the body may be held in two selected positions, with means permitting this adjustment which are simple in construction, positive in operation, easy to manipulate, and which do not-include any extended members or portions to cause personal injury.

The advantages will be apparent from the following detail description, taken in connection with the accompanying drawings.

Fig. 1 is a perspective of a frame embodying this invention;

Fig. 2 is a plan view;

Fig. 3 is a side elevation;

Fig. 4 is a side elevation taken on line 44, Fig. 1;

Fig. 5 is a view similar to Fig. 4 with the frame in an alternate position; and.

Fig. 6 is a perspective of a link which permits the adjustment.

In the drawings the invention is illustrated in connection with a frame of one conventional or commercial construction, but it may be understood that this invention may be applied to frames other than that specifically shown. It may be applied, for instance, to frames of the structure shown in Burst Patent N 0. 2,013,910.

As specifically shown, the frame includes a body supporting member in the form of a yoke having on each side of the frame a side bar I. A second body supporting member at the front of the vehicle, also in the form of a yoke, has side bars 2 pivoted at their ends to the bars I by pins or rivets 3.

The body supporting members are sustained by collapsing frame members above a running gear, not shown. The sustaining members include a pair of scissor bars 4 and 5 (one bar on each side of' the frame) pivotally connected by pins 6. A handle bar I, one on each side of the frame, is pivoted at 8 to an extended end of the bar I and at 9 to the upper end of the scissor bar 4, with its end bent to form an abutment I0 releasably held by a latch ll pivoted on the upper portion of the bar 4, as clearly shown in the drawings.

The upper ends of the scissor bars 5 are pivoted That part of the structure which has been described in detail, is old in the art and forms the environment for the present invention; it being understood, however, A that the particular construction has been selected, shown and described merely by way of illustration, since the present improvement may be applied to frames of different, construction and even to frames which are not collapsible.

,In accordance with this invention means are provided to permit the front body supporting member having the bars 2 to be held ineither of two selected positions, as shown in full lines and in dotted lines in Fig. 3, and as shown comparatively in Figs. 4 and, 5. These means include a link l2, one on each side of the frame, in cooperation with a downwardly directed extension [3 on the end of the bar I.

The link I2 is pivoted by a pin 14 to the bar 2 and cooperates with holding means on the extension [3. The link l2 has a hook-shaped slot IS in which slides a pin l6, secured at an intermediate point on the extension I3. As clearly shown in the drawings, the pin I-B engages in the point of the slot [5 to hold the frame member 2 in uppermost position. This is best illustrated in Figs. 3 and 4.

The link I2 has an abutment l1 formed by a notch on one of its sides and positioned to engage a laterally extending pin IS on the end of the extension l3, as shown in Fig. 5, when the front framemember having the bars 2 is lowered.

It may now be understood that the body supporting members may be extended as shown in Fig. 1, in which the front portion which includes the side bars 2 is supported by the link [2, as shown in Figs. 1, 3 and 4, with the link [2 in such a position that the pin IS on the extension I3 and extending into the slot I5 is in the point of the hook-shaped slot. By lifting the front end of the frame, which includes the bars 2, the link i2 may be shifted so that the pin l6 lies in the shank of the slot and the front end of the frame may then be lowered until the abutment l1, formed by a notch in the link 12, engages the laterally extending pin [8 on the bottom of the extension l3. Since the pin [6 is still in the slot l5, as shown in Fig. 5, the link 12 is braced and the front frame member is held securely in its lowermost position. In changing the adjustment from the lowermost position, that is the position shown in Fig. 5, to the uppermost position, that shown in the remaining figures, it is necessary merely to lift on the end of the front frame member which includes the side bars until the link assumes a position Where the pin I6 is in the point of the slot 15.

It will be apparent from the foregoing description that the invention accomplishes its objects. The means employed are simple in construction, positive in operation and easy to manipulate. The link l2 presents no extended points to cause personal injury, or which by accidental contact might cause displacement of the parts.

Various changes may be made in the details of construction, within the scope of the appended claims, and the improvement may be placed in an environment substantially different from that here specifically shown and described, without departing from the spirit of this invention. The invention is adapted and intended to be used in connection with doll buggies, as well as baby carriages, and it will be understood that the expression baby carriage is intended to include doll buggies as well.

I claim:

1. In a frame for baby carriages having a rear body supporting member, a front body supporting member pivotally attached to said rear member, and a forwardly and downwardly extending arm rigid with said rear member, the improvement comprising a link pivoted to said front member having a hook-shaped slot, a pin secured to said arm extending laterally into said slot and positioned to engage in the point of the hook of said slot when said front member is in uppermost position to support said front member, and an abutment on said arm to limit the lowermost position of said front member.

2. In a frame for baby carriages having a rear body supporting member, a front body supporting member pivotally attached to said rear member, and a forwardly and downwardly extending arm rigid with said rear member, the improvement comprising a link pivoted to said front member having a hook-shaped slot, a pin secured at an intermediate point on said arm extending laterally into said slot and positioned to engage in the point of the book of said slot when said front member is in uppermost position to support said front member, and an abutment on the lower end of said arm below said pin to limit the lowermost position of said front member by engagement with said link in cooperation with the action of the pin in the slot.

3. In a frame for baby carriages having a rear body supporting member, a front body supporting member pivotally attached to said rear member, and a forwardly and downwardly extending arm rigid with said rear member, the improvement comprising a pin pivoted to said front member having a hook-shaped slot, a pin secured at an intermediate point on said arm extending laterally into said slot and positioned to engage in the point of the hook of said slot when said front member is in uppermost position to support said front member, an abutment formed by a notch in one side of the link, and a laterally extending abutment on the lower end of said arm below said pin to engage in said notch when said member is in lowermost position and thereby support said member in that position.
