The mounting portion 240 can be pivotally connected to a connecting member 242. The connecting member 242 can be movably combined with a content portion 245 disposed on the seat plate 204 by a rigid connecting rod body. The connecting member 242 can have a first end 242A and a second end 242B. The first end 242A is rotatably connected to the lower end portion 222A of the rod body 222. The second end 242B has one or two opposite sides respectively provided with a convex portion. The shaft 243 and the protruding shaft 243 are movably coupled to the corresponding guiding grooves 244 provided in the seat plate 204.

The guiding groove 244 may be formed on one or two opposite sides of the content portion 245 such that the second end 242B of the connecting member 242 is movably assembled to the guiding groove 244. As shown in FIGS. 7 and 8, the guide groove 244 has an elongated strip shape which is extendable from a position close to the fixing groove 216 toward another position away from the fixing groove 216. More specifically, the guide slot 244 can extend in a direction that is approximately parallel to the direction in which the stop structure 208 is in the collapsed state, for example, parallel to the front and rear horizontal axes of the seat plate 204.

In order to facilitate the assembly of the connector 242 and the seat plate 204, the guide slot 244 can communicate with the opening 246 at the upper side 204 of the seat plate 204, through which the second end 242B of the connector 242 can be guided. The slot 244 is removed to completely disengage the connector 242 from the guiding slot 244, and the second end 242B of the connector 242 can be inserted into the guiding slot 244 to engage the connector 242 with the guiding slot 244. The position of the opening 246 can be adjacent to the fixing groove 216 and the distance from the fixing groove 216 is smaller than the length of the connecting member 242.

One side of the elastic tongue 254 is provided with a protruding fastener 256. When the lower end portion 222A of the rod portion 222 is engaged with the fixing groove 216, the protruding fastener 256 will be engaged with the lower end portion 222A of the rod portion 222. Although the latch portion 252 has been used to explain the incorporation of the stop structure 208, another stop structure, such as the aforementioned stop structure 108, may be provided with the same latch structure.

Next, an exemplary operation of the stop structure 208 will be described in conjunction with Figures 7 through 12. As shown in FIGS. 7 and 8, the stopper structure 208 is in an upright state as the lower end portion 222A of the rod portion 222 is coupled to the fixing groove 216. The protruding fastener 256 of the latch portion 252 is elastically engaged with the mounting portion 240 of the lever portion 222 to securely lock the blocking structure 208 in the upright state to the fixing groove 216. At the same time, the connector 242 passes through the slit 248 to engage the male shaft 243 on the second end 242B of the connector 242 to the guide groove 244. To prevent the opening 246 from catching the toddler's finger, the stem portion 222 can include an annular flange 258 that can provide the function of closing the opening 246 on the upper side 204A of the seat pan 204 when the stop structure 208 is in the erect condition.

If the stop structure 208 is to be adjusted to a collapsed state, the engagement of the protruding fastener 256 from the mounting portion 240 can be caused by pressing the resilient tab 254. After the lock is released, the stopper structure 208 can be pulled upward in the Y-axis direction of the fixing groove 216 to disengage the lower end portion 222A of the rod portion 222 from the fixing groove 266 as shown in FIG. When the rod portion 222 is pulled upward, the connecting member 242 is rotatable relative to the rod portion 222 and is rotated and slid relative to the seat plate 204. In particular, the first end 242A of the connector 242 can be moved through the interior of the securing slot 216, while the second end 242B of the connector 242 is translated toward the other end of the guiding slot 244.

Figures 10 through 11 are diagrams showing the stages of an embodiment of the embodiment in which the blocking structure is in a collapsed state. As shown in FIGS. 10 and 11, when the lower end portion 222A of the rod portion 222 is completely separated from the fixing groove 216, the stopper structure 208 is rotatable relative to the connecting member 242 to collapse the blocking structure 208 toward the seat plate 204. The connector 242 is caused to rotate relative to the seat plate 204, and the second end 242B of the drive connector 242 slides along the guide slot 244 toward an end that is aligned with the opening 246. As shown in Fig. 11, the stopper structure 208 is substantially collapsed in the horizontal direction on the upper side 204A of the seat plate 204. In addition, the first end 242A of the connecting member 242 coupled to the lower end portion 222A of the stem portion 222 protrudes approximately directly above the opening 246 that is offset from the fixing groove 216, and the second end 242B of the connecting member 242 can be guided along The slot 244 moves substantially aligned with the position of the opening 246 and the stop portion 250. In other words, the collapsed stop structure 208 is completely outwardly disposed and disengaged from the seat plate 204, but the stop structure 208 is still coupled to the seat plate 204 by the connector 242, and the connector 242 is substantially vertical. The stop structure 208 is parallel to the Y-axis of the fixed slot 216.

Referring to FIG. 12, the retaining portion 250 can be disposed at a particular position such that the second end 242B of the connector 242 (particularly the male shaft 243) is fixedly coupled to the guide slot 244. For example, the stop portion 250 can be formed on a side wall portion of the content portion 245 and is positioned adjacent to the middle end of the guide groove 244 and aligned with the opening 246. If the stop structure 208 is to be completely removed from the fixing groove 216, the stop structure 208 can be pulled up in the Y-axis direction of the fixing groove 216 to overcome the slight resistance of the convex shaft 243 by the stop portion 250. The second end 242B of the connector 242 can then be disengaged from the guide slot 244 and the connector 242 can be pulled upwardly from the opening 246 to completely remove the stop structure 208 from the seat plate 204. When the stop structure 208 is completely removed from the seat plate 204, the connection of the second end 242B of the connector 242 to any other component is free.

If the stop structure 208 is to be installed, first, the second end 242B of the connector 242 can pass through the opening 246 and into the guide slot 244. Next, the lower end portion 222A of the rod portion 222 is fitted into the fixing groove 216 along the Y-axis of the fixing groove 216, so that the stopper structure 208 can be joined to the seat plate 204. When the latch portion 252 locks the stop structure 208, the stop structure 208 is in an upright position.

The structure and method have at least one advantage in that a stop structure can be provided that can be adjusted from an engaged state to a collapsed state and positioned substantially horizontally on the seat plate, and when needed It can be easily removed from the seat plate. Therefore, the blocking structure can be coupled to the infant seat using a more flexible method. The stop structure described above is simple in construction and can be manufactured in a cost effective manner.
