'. Louis, Mo.; said Miller assiguor to Welsh Company St. Louis, Mo., a corporation of Missouri Application October 30, 1953, Serial No. 389,431 6 Claims. (01. 280-36) This invention pertains to baby carriage frames of the collapsible type.
Frames of this type have become popular, in which each side frame involves a pair of bars crossed at their middle portion in the form of an X. Such an X-frame usually spans the whole side area of the baby carriage and as far as its appearance is concerned is a very conspicuous part of the design. Such an X-frame is ungraceful and detracts from the general appearance of the article. An object of this invention, therefore, is to provide a col lapsible frame which has a more attractive appearance and the outline of which can be blended with the general contour of a baby carriage.
Further objects will appear from the following description taken in connection with the accompanying drawings, in which i Fig. 1 is a perspective view of a baby carriage equipped with a collapsible frame embodying this invention;
Fig. 2 is a side view somewhat enlarged of one of the side frames of the carriage shown in Fig. 1.
Fig. 3 is a view similar to Fig. 2 showing the side frame in collapsed position;
Fig. 4 is an enlarged fragmentary rear view about on line 44 of Fig. 2;
Fig. 5 is an enlarged section on line 5--5 of Fig. 2;
Fig. 6 is an enlarged section on line 66 of Fig. 2; and
Fig. 7 is an enlarged fragmentary 'view on line 77 of Fig. 2.
Referring to the drawings, the collapsible frame consists essentially of a pair of bars indicated at A and B respectively. These bars may be of flat metal strip of approximately 1 inch in width by inch in thickness, bent edgewise to the form shown. These bars may, however, be made of other materials and formed in any manner suitable to the material. In the embodiment shown, the bar A has a middle portion 1 extending substantially horizontally when the frame is in its extended position as shown in Fig. 2. The rear portion 2 of the bar A is turned upward as shown in Fig. 2 and its forward portion 3 is turned downward as shown in the same figure.
Similarly, the bar B has a middle portion 4 extending horizontally, its forward portion 5 being turned upward and its rear portion 6 being turned downward. This gives each of these bars the general form of the letter S and for convenience they will be designated hereinafter as 8- bars. While in the form shown in Fig. 2, the middle portions 1 and 4 are each straight for a certain length thereof; this is not an essential feature in all cases, as the curves of the portions 2 and 3 may join each other directly at the middle portion without such a straight section.
The bars A and B are connected together at their middle portions by a slidable connection. A slot 23 in the bar A and a similar slot 24 in the bar B, each extending along the middle portion of the bar, are arranged to receive a pin 25 traversing both slots as shown in Fig. 5 with suitable spacer washers therebetween.
In order to support the baby carriage on its wheels, a
"i e j. y
. member 7 in the usual manner and are in turn supported on wheels 12a.
What has thus far been described constitutes one side frame of the carriage, a duplicate side frame being provided on the opposite side thereof. Pivoted at 13 to the upturned forward end of the member B is a supporting member 14. The body 15 of the baby carriage may be of any suitable design and may be provided with an upper frame 16 which may be attached in any suitable manner to the supporting members 14 at the two sides thereof so as to support the body on theframe. The rear portion 2 of the bar A is made shorter than the forward portion and is pivoted at its terminal at 17 to a handle bar frame 18. The lower end of the frame 18 extends below the pivot 17 and is arranged to engage a latch 19 pivoted at 20 to the bar A and biased by a spring 21. When engaged by this latch, the frame 18 is held upright as shown in Figs. 1 and 2. The supporting member 14 is also pivoted to the frame 18 at 22.
The lower part of the handle bar frame 18 has also pivoted, thereto at 26a link 27 shaped to conform to the portion 2 of the bar A so as to be hidden thereby when the frame is in extended position as in Fig. 2. This link is pivoted to the bar B at 28. These connections provide operating mechanism for collapsing the frame. When the frame is in its extended position as in Fig. 2, the pin 25 is at the forward end of the slot 23 and at the rear end of the slot 24. Thus, whenthe handle bar frame is engaged by the latch 19, the frame is held rigid in this extended position. In order to collapse the frame, the latch 19 is pulled downward so as to disengage the handle bar frame which later is then moved forward or to the right, Fig. 2. This movement causes said frame to pivot at 17 on the bar A, moving the member 14 to the right and the link 27 to the left, 'Fig. 2. This action causes the bars A and B to slide onthe pin 25 and at the same time to swing on said pin as a pivot to the collapsed position shown in Fig. 3. The body 15 at the same time sinks downward between the two side frames to a position in which it practically rests on the axles 12. The frame may be extended to its original position by moving the handle bar frame 18 rearward. This moves the link 27 to the right, and sections 2 and 3 and the member 14 to the left, sliding the bars A and B on the pin 25 to the extended position of Fig. 2.
It will be seen that this invention provides a simple collapsible frame which has the geenral contour of the baby carriage body at its upper portion. In other words, the portions 2 of the bar A and 5 of the bar B may be formed to follow the contour of the adjacent partsof the body 15. The lower portions 3 and 6 may then be formed to have the appearance of feet upon which the body rests. This is believed to have a much more attractive appearance than the former X-frame.
Various changes may be made in the details of construction, within the scope of the appended claims, without departing from the spirit of this invention. Parts of the invention may be used without the whole and improvements may be added while retaining some or all of the advantages of the invention.
