Here, an example of a conventional baby carriage is disclosed in Korean Patent Laid-Open No. 10-2012-0030621 (the invention is called a baby carriage). As shown in FIGS. 1A and 1B, a body 10 having front and rear wheels, a seat 11 mounted on an upper portion of the body 10, And a handle (12). A rotating member 15 that rotates in a clockwise or counterclockwise direction on the side surface is provided at a joint portion between the body 10 and the front wheel 13 or the rear wheel 14 and a joint portion between the body 10 and the handle 12. [ And a fixing member 17 through a spring 16 and a knob member 18. As shown in Fig. Therefore, when the handle member 18 is pulled, the fastening member 17 and the rotary member 15 are disengaged from each other when the fastening member 17 is rotated while the elastic force of the spring 16 is overcome. In this state, The fixing member 17 rotates in the original direction by the elastic force of the spring 16 and the fixing member 17 and the rotary member 15 are fastened again when the knob member 18 is released. At this time, by rotating the rotary member 15, the front wheel 13 or the rear wheel 14 can be rotated forward / backward with respect to the body 10, and the handle 111 can be rotated forward / backward.

As shown in FIG. 1C, the body 10 and the seat mounting portion of the stroller 20 are fixed to the fixing groove 20 (see FIG. 1C), as disclosed in Korean Patent Application No. 10-2012-0030626 filed by the same applicant A rotary shaft 21 rotating in a clockwise or counterclockwise direction in plan view and a fixing member 17 provided through a spring 16 and a pull member 18 so as to be engaged with the fixing groove 20. Therefore, when pulling the knob member 18, the elastic force of the spring 16 is overcome so that the fixing member 17 is rotated and the engagement with the fixing groove 20 is released. After the rotation shaft 21 is rotated, 18 is released, the fixing member 17 rotates to its original position due to the elastic force of the spring 16, and the fixing member 17 and the rotary shaft 21 are fastened again. At this time, by rotating the rotary shaft 21, the seat 11 can be rotated in a clockwise or counterclockwise direction with respect to the body 10.

However, since the coupling force between the rotary member 15 and the fixing member 17 of Fig. 1B, the rotary shaft 21 of Fig. 1C and the fixing member 17 depends entirely on the elastic force of the spring 16, The rear wheel 14, the handle 12 and the seat 11 can be rendered inoperative if the elasticity of the front wheel 13, the rear wheel 14,

Of course, the shape of the support member 124 may be a straight shape or a "B" shape, and one side may be directly mounted on the support frame 121 or mounted on the first body 126, It may be any shape that can be rotated by the movement of the shaft.

The one end side portion of the guide member 125 is mounted on the sliding member 122 so as to rotate in the axial direction, and the other end side portion is mounted on the support member 124 so as to rotate axially. The guide member 125 is, for example, substantially "b" shaped and moves rearward together with the sliding member 122, at which both sides are axially rotated relative to the sliding member 122 and the supporting member 124 . Of course, the guide member 125 may have a linear shape or a " C "shape, and one side portion may be mounted on the sliding member 122 to move the supporting member 124 in the axial direction Any shape that can be made is acceptable.

The supporting portion 120 configured as described above supports the third handle frame 115, that is, the handle portion 110, with respect to the support frame 121 when it rotates rearward (in the direction of the first rear wheel 132). More specifically, the guide bar 123 pushes the sliding member 122 backward when the third handle frame 115 axially rotates rearward and the guide bar 123 is pushed rearward, The support member 124 rotates while being moved. The front wheel 131 is folded in one direction on the side of the front wheel frame 131a along with the rotation of the support member 124. The coupling operation of each of these components ensures that the third handle frame 115, i.e., the handle portion 110, can rotate axially rearward.

When the third handle frame 115 rotates rearward with respect to the first body 126, the guide bar 123 pushes the sliding member 122 backward. Of course, the guide bar 123 is rotated about the axis of the third handle frame 115 and the sliding member 122. Then, the sliding member 122 moves backward along the support frame 121 to move the guide member 125. The support member 124 rotates downward with respect to the first body 126 together with the movement of the guide member 125. Further, the first front wheel 131 is rotated axially rearward. The folded state of the handle portion 110 is shown in Fig. 6B.

Next, the first handle frame 112 is slidably inserted into the second handle frame 113. Further, the handle 111 is axially rotated upward to be brought into contact with the second handle frame 113. Here, the first rotating body 114a may be rotated to release the fastening of the stacking frame 114 and the second handle frame 113, and then the stacking frame 114 may be moved to the lowermost position. Thereafter, the first rotating body 114a may be rotated to the original position to fasten the stacking frame 114 and the second handle frame 113 together.

Finally, the second rotating body 114c is rotated to unlock the stacking frame 114 and the second handle frame 113, and then the stacking frame 114 is rotated so as to be laid down. Thereafter, the second rotating body 114c may be rotated to the original position to fasten the loading frame 114 and the second handle frame 113 again. The state in which the loading mechanism 100 is folded to the minimum size in such a manner is shown in Fig. 6C.

Of course, the folding sequence described above may be mutually exclusive. Also, the order of unfolding the stacking mechanism 100 in the folded state is reversed, and the order may be mutually exchanged.
