United States Patent O PUSHER HANDLE CONTROL MECHANISM FOR BABY CARRIAGES, STROLLERS, AND THE LIKE Alban M. Boudreau, Gardner, Mass., assignor to Hedstrom-Union Company, Fitchburg, Mass., a corporation of Massachusetts Application October 17, 1951, Serial No. 251,749

4 Claims. (Cl. 280-4736) handle is movable between two operative positions so that either end of the vehicle may be the leading end, when the vehicle is being pushed by means of the pusher handle. The invention provides improved mechanism for controlling the movements of the pusher handle of such a vehicle as the pusher handle is being moved from one to the other of its two operative positions, and for effectively locking the pusher handle in each of its two operative positions.

It is among the objects of the invention to provide pusher handle mounting and control mechanism for baby and doll carriages, strollers, and the like, whereby a pusher handle more readily and conveniently may be shifted between two operative positions at opposite ends of the vehicle, as compared with prior comparable mechanisms, and be elfectively maintained in either position.

Another object of the invention is to provide pusher handle control mechanism for baby and doll carriages, strollers, and the like, wherein the pusher handle is swingable' between two operative positions at opposite ends of the vehicle body and wherein its movement to either of said operative positions is stopped by a pair of pivoted longitudinally slotted bars in whose slots projections on the pusher handle slidably engage, each said bar having pivoted means thereon for coaction with a said projection to securely lock the pusher handle in either of its said operative positions.

It is, moreover, my purpose and object generally to improve the structure and efliciency of pusher handle control mechanisms and more especially such mechanisms for controlling and locking reversible pusher handles of baby and doll carriages, strollers, and the like, wherein the handles are movable between two operative positions at opposite ends of the vehicles.

In the accompanying drawing: 1

Fig. 2a is a view similar to Fig. 1a but looking at the inner side of the locking means shown in full lines in Fig. 2;

Fig. 3 is a top plan view of the carriage with the pusher handle in its Fig. 1 position; and

2,726,876 Patented Dec. 13, 1955 Fig. 4 is a cross-sectional view on line 44 of Fig. 1, on a larger scale.

Referring to the drawing, the inverted generally U- shaped pusher handle 10 is shown pivotally mounted on the body 12 of a baby carriage although it will be apparent that the type or style of the vehicle may be variously modified without affecting the nature and scope of the invention which is applicable to baby and doll carriages, strollers, and the like, where it may be desirable to employ a pusher handle for pushing the vehicle with either end of the vehicle selectively constituting the leading end.

The particular carriage body 12 herein represented has a tubular frame 14 extending all around each side of the body, and the arms of the pusher handle 10 have their lower ends pivotally secured at 16 to the lower horizontal portions 15 of the tubular frames 14. The pivotal securements 16 are located substantially centrally between the opposite ends of the body 12, and the pusher handle 10 extends a substantial distance above the body 10 so that it may be swung about its pivotal axis at 16 between two operative positions indicated respectively in full lines and in dotted lines in Fig. 1. When the vehicle body has a conventional hood thereon, as represented at 18, the pusher handle 10 must clear the hood when moving between its two operative positions- The movements of the pusher handle 19 are controlled and limited by a pair of longitudinally slotted bars 20, one at each side of the vehicle body 12, each pivotally connected at 22 to the upper horizontal portion 15' of the adjacent tubular frame 14, with the pivotal axis 22 of the two bars 20 substantially in the vertical plane of the pivotal axis 16 of the pusher handle 10. The slot 21 of each bar 20 is relatively long, and a pin 24, or the like, projects from each arm of the pusher handle and slidably engages in the slot 21 of the adjacent bar 20. Hence, when the pusher handle 19 is swung about its pivotal axis 16 from its full line position of Fig. 1 to its dotted line position in Fig. 1, or from its full line position in Fig. 2 to its dotted line position in Fig. 2, the bars 26 swing about their pivotal axis 22 in direction opposite to the direction of movement of the pusher handle, with the pins 24 riding along the side walls of the slots 21 in bars 20, and with end walls of the slots 21 limiting the swinging movement of the pusher handle in either direction.

It is a feature of the invention that each bar 20 extends a little beyond the adjacent pusher arm when the pusher arm is stopped at either limit of its permissible swinging movements, and each has pivotally mounted at 26 on this projecting end a locking member 28 having the oppositely disposed hook portions 28a, 28b. As best seen in Figs. 1a, 2a and 4, each of the pins 24 projects through and substantially beyond the adjacent slotted bar 20 with its projecting portion preferably enlarged for constituting a locking pin portion 24' with which the locking member 28 can engage to lock the pusher handle 10 in either of its operative positions. When the pusher handle 10 is in its full line operative position of Fig. 1, the locking member 28 may be swung counter-clockwise from its dotted disengaged position of Fig. 1 to its full line position thereby to engage itsposition thereby to engage its hook portion 28b over the adjacent locking pin portion 24 (see Fig. 2a) to securely lock the pusher handle in its full line operative position of Fig. 2.

When the pusher handle is to be locked by engagement of the. hook portions 28a with the locking pin portions 24', or is to be unlocked, the other hook portions 28bconstitute handles facilitating manual actuations of the locking members 28 into and out of locking engagement withthe pin portions 24'. Similarly, when actuatinghook portions 28b into and out of engagement with pinportions 24", the hook portions 23a conveniently may f serve as handles.

The particular pusher handle 10' as herein represented has each of its arms formed in two parts 10a, 10b which 7 are pivotally connected together at the pin projections 24 whichserve as pivots for collapsing the upper portion of i the pusher handle against the top of the'carriage body. The lower'portions 10a maybe formed of flat bar stock handle is to be collapsed.

It will be apparent from the foregoing description, in connection with the drawing, that I have provided a simple and extremely effective pusher handle control and locking mechanism for' baby and doll vehicles, and it is intended that the patent shall cover, by suitable expres. sion in the appended claims, whatever features of patentable novelty exist in the invention disclosed.

I claim as my invention: 7
