が保証される。By actuating the operating device 36, folding can then be achieved. That is, as shown in FIG. 7, the push button 132 is pushed into the activation member 102 against the elastic force of the spring 134, and then the activation member 102 is pushed into the central body 100 while the push button 132 is kept pressed. . Movement of the activation member 102 upwardly in FIG. 6 causes the pin 116 to move upwardly in the slot 103, 105 through the hole 118. Therefore, the left and right operating pieces 98, 98 rotate counterclockwise and clockwise around the pillars 104, 104, respectively. This rotation causes the holes 110, 110 of the operating pieces 98, 98 to move away from each other. As a result, the wires 90 held in the chain holes are mutually drawn toward the upper center of the push rod 28. When the wire 90 is pulled upward against the elastic force of the spring 65 that always urges the slider 44 downward, the slider 44 moves to the case 4.
Move upward within 2 (Fig. 13). Therefore, the notch 74 of the slider 44 is released from the upper pin 7B of the rear leg 24. When the push rod 28 is lifted upward in this state, the lower ends of the front legs 22 and the lower ends of the rear legs 24 approach each other, and at the same time the push rod 28 rotates via the pin 48 of the arm 52 and the pin on the column piece 92, and the push rod The lower end of 28 can be separated from the rear leg 24 (FIG. 14). Next, when the push rod 28 is pushed downward while the activation member 102 is pushed into the operating device 36, the push rod 28
rotates about pin 48 of arm 52, and at the same time arm 52 rotates about screw 95 (FIG. 1) on post piece 92. For this reason, the protrusion 50 provided on the arm 52, which rotates around the screw 95, advances to the final position while tracing the trajectory shown by the broken line in FIG. After that, when the activation member 102 is released,
Due to the spring 65 forcing the slider 44 downward,
The operating piece 98 is returned from the dashed line position to the solid line position, and the protrusion 86 of the slider 44 is lowered from the solid line position in FIG. The folding position shown in FIG. 15 is obtained. At this position, the arm 52 is immovable, and expansion work is not possible from this position. In this folded position, the front and rear wheels are placed side by side on the ground, ensuring that the stroller remains upright.

いて進み最上位置まで至る。In the present invention, actuating member 102 is actuated to move slider 44.
The notch 74 was pulled out from the upper pin 76 (Fig. 13).
After that, once the push rod 28 has been slightly pushed down, the same operation can be accomplished by immediately releasing the push-in of the activation member (02). That is, when the activation member 102 is released, the slider 44 moves to the position shown in FIG. Although the arm 52 returns to its position, the trajectory of the arm 52 does not change, so the protrusion 50 on the arm 52 advances as shown by the broken line in FIG.
6, the protrusion 50 of the arm collides with the protrusion 8 of the slider.
The slider 44 is pushed upward against the force of the spring 65 along the circular surface or slope 9i of the slider 6, and moves along a predetermined trajectory until it reaches the uppermost position.

ときに第12図の位置が得られるからである。To assemble the stroller from the folded position to the expanded position, simply remove the protrusion 86 of the slider 44 from the track of the protrusion 50 of the arm 52 (indicated by the dashed line in Figure 18.17), and then The slider 44 may be moved upward within the case 42 so that it can move freely. For this purpose, the activation member 102 can be pushed into the operating device 36 against the force of the spring 65. In this way, when the protrusion 86 of the slider 44 is removed from the track and the push rod 28 is pulled up slightly, the slider 44 is operated in the opposite direction to the folding operation.
The tongue-like portion 66 of the rear leg 24 collides with the rear leg 24. Then starting member 1
When the slider 02 is released, the notch 74 of the slider collides with the upper pin 76 of the rear leg 24, and the stroller assembly is locked in the expanded position. Of course, during the folding operation, the -carrying slider 44
The same effect can be obtained even if the activation member 102 is immediately released after the projection 86 of the arm 52 is released from the locus of the projection 50 of the arm 52 and the push rod 28 is slightly pulled upward. This is because after the circular surface or slope 45 formed on the surface opposite to the notch 74 of the slider 44 collides with the upper pin 76, the slider 4
This is because the slope 45 of No. 4 moves along the upper pin 76, causing the slider 44 to escape upward, and when the slope 45 passes over the pin 76, the position shown in FIG. 12 is obtained.
