. - , . . . = - -, DESCRIPTION OF THE PREFERRED EMBODIMENT:
. ' - As illustrated in Figure 1, the baby walker or stroller consists of a top member 10 provided with an opening 12 and a seat 14 suspended below the opening 12 in such manner as to support the child. The reference numeral 16 designates the bottom member which is provided on the underneath side with a plurality of roll~rs 17 permitting the bottom member 16 to move along a surface~ The construction previously described is known in the prior art and need not be explored in detail.
As illustrated in Figures 2-4, the inner portions of the side walls of the bottom member 16 are provided with longitudinal slots 18 defining cavities within the walls, and pins 20. The ; ' -2-. ..
, ` 105~'~5;2 top and bottom members 10 and 16, respectively, are operably ccnnected to each other with the struts 22 and 24, as will now be described.
The strut 22 is journalled for rotation within blocks 26 which are secured to the underneath surface of the rear of the top member 10, as illustrated in Figures 7 and 10. The strut 22 terminates in lower ends designated by the reference numeral 28, each of which passes through its corresponding slot 18 into the cavity within the walls of the bottom member 16. Each of the ends 28 of the strut 22 is provided with a roller 30, as illus-trated in Figures 3 and 4, which is positioned within the cavity to thus serve the dual purpose of fixedly securing the end 28- -in relationship to slot 30 while permitting the roller 30 to move along the bottom surface 32 of the cavity defined by the slot 18.
The strut 24, as illustrated in Figure.9, is mounted to rotate within a block 34 that is mounted to move longitudinally below the'top member 10 along the rail 36. The strut 24 termi~ates downwardly in e,nds 38 which are provided with openings thro~gh , : . ., ., .. ~ . . .. . .

The block 34, which as illustrated in Figure 9 is arranged to slide between the underneath surface of the top member 10 and the rail 36, is provided with a screw-threaded shaft 50 which passes through the slot 48 of the rail 36 and an opening located within the latching member 52 which is provided with teeth 54 which mesh with the teeth 46 of the rail 36. A
,knob 54 is appropriately threaded on the shaft 50 such that as it is turned in one direction the latching member'52 is forced downwardly into engagement against the rail 36 until the respec-tive teeth 54 and 46 engage at which time the block 34 is locked in position. It will also be apparent that as the knob 54 is.
rotated in the opposite direction the teeth 54 and.46 disengage and it is possible,to move'the block 34 and the strut 24 which passes therethrough longitudinally along the underneath surface of the top member 16. -As illustrated in Figures 3 and 4, as the position of theblock 34 is changed, the ends 28 of the strut 22 slide along the bottom member 16 and the ends 38 of the strut 24 rotate about the , pins 20. . . . ; . .
Turning now to Figures 5-7, it will be apparent that as .
the knob 54 is loosened disengaging the teeth 46 and 54 it is :possible to collapse the walker to the position illustrated in Figure 5 wherein the top and bottom members 10 and 16, respec-tively, are positioned near each other. Thus, the walker may be conveniently stored which is particularly helpful when it is desired to store the walker in an automobile during a tripu Figures 6 and 7 illustrate various stages of raising the height of the walker, it being understood that the teeth 46 and 54 _~_, ~ . .. .

. - , . . . = - -, DESCRIPTION OF THE PREFERRED EMBODIMENT:
. ' - As illustrated in Figure 1, the baby walker or stroller consists of a top member 10 provided with an opening 12 and a seat 14 suspended below the opening 12 in such manner as to support the child. The reference numeral 16 designates the bottom member which is provided on the underneath side with a plurality of roll~rs 17 permitting the bottom member 16 to move along a surface~ The construction previously described is known in the prior art and need not be explored in detail.
As illustrated in Figures 2-4, the inner portions of the side walls of the bottom member 16 are provided with longitudinal slots 18 defining cavities within the walls, and pins 20. The ; ' -2-. ..
, ` 105~'~5;2 top and bottom members 10 and 16, respectively, are operably ccnnected to each other with the struts 22 and 24, as will now be described.
The strut 22 is journalled for rotation within blocks 26 which are secured to the underneath surface of the rear of the top member 10, as illustrated in Figures 7 and 10. The strut 22 terminates in lower ends designated by the reference numeral 28, each of which passes through its corresponding slot 18 into the cavity within the walls of the bottom member 16. Each of the ends 28 of the strut 22 is provided with a roller 30, as illus-trated in Figures 3 and 4, which is positioned within the cavity to thus serve the dual purpose of fixedly securing the end 28- -in relationship to slot 30 while permitting the roller 30 to move along the bottom surface 32 of the cavity defined by the slot 18.
The strut 24, as illustrated in Figure.9, is mounted to rotate within a block 34 that is mounted to move longitudinally below the'top member 10 along the rail 36. The strut 24 termi~ates downwardly in e,nds 38 which are provided with openings thro~gh , : . ., ., .. ~ . . .. . .
. which the pins 20 extend thus permitting the ends 38 to rotate , about the pins 20. ' ' ., . ' The struts 22 and 24 intersect on each side of the walker at.the rotating cylinders 40. From Figure 2,,,it wili be apparent that the struts 22 and 24 pass through their respective cylinders . 40, while the pin 42 connects the cylinders 40 to each other.
.~ In this manner, as the struts 22 and 24 adopt different positions~
to be described hereinafter, their respective cylinders 40 rotate about the pin 42. , With reference to Figures 2 and 8, it is apparent that the . rail 36 is appropriately mounted, for example by screws 44, to _ _ ., the underneath side of the top member 10. The rail 36 is ~ ,' .
