When pulling upwards while rotating in the), the operating rod 312 of the first support bar 310 is rotated and rotated in one direction (counterclockwise direction in FIG. 4), and the second support bar 320 is rotated in the other direction ( Clockwise).

At this time, the seatback 410 of the bidirectional seat 400 is rotated together by the rotation of the turning bar 330, the other side of the seatback 410 is disposed so as to face the other side of the main body 100, seat cushion 420 ) Is moved upward and positioned at a point higher than the height at which the handle is positioned, thereby completing the conversion from the cart to the stroller.

As described above, the present invention is a structure that is converted between the stroller and the cart car by changing the direction of the seat, has a significant effect compared to the conventional stroller. This will be described in detail the superior advantages of the present invention compared to the conventional stroller as follows.

First, the present invention can reduce the production period, compared to the case of separately manufacturing a conventional stroller and cart car. Conventionally, in order to manufacture each stroller and cart car, two manufacturing processes must be made for the corresponding product, such as manufacturing a design for each configuration, processing a product according to the manufactured design, and designing each product. Therefore, it takes a lot of production period. However, in the case of the baby carriage according to the present invention, since the design, processing, and design are manufactured in one operation, the production period may be shortened.

Second, the present invention can reduce the manufacturing cost than when the conventional stroller and cart cart separately manufactured. If the stroller and cart car are manufactured separately, the manufacturing process takes twice to produce each product, which incurs a lot of cost in production cost. However, since the present invention is made of one stroller capable of implementing the stroller function as well as the cart car function, the manufacturing cost can be reduced and the delivery cost can be lowered. This, in turn, provides the effect of reducing the purchase cost of the consumer.

Third, the present invention can shorten the delivery time of the product than when manufacturing and delivering the stroller and cart cart separately. That is, the present invention can shorten the delivery time is shorter than the manufacturing period of the conventional stroller and cart cart separately.

Fourth, the present invention may increase the output per unit time than when manufacturing a conventional stroller and cart cart separately. The present invention can produce a high value-added stroller product that can implement the stroller and cart car functions at the same time, it is possible to achieve a production effect such as producing a stroller and cart car at the same time in a short time to increase the product yield.

Fifth, the present invention is easier to store and repair the product than when the conventional stroller and cart cart separately manufactured. When the stroller and the cart cart are separately manufactured, a lot of space is required because the stroller and the cart cart must be stored separately. If both the stroller and the cart cart are broken, it is troublesome to contact the company that produced the product for repair. However, the baby carriage according to the present invention may be repaired for one product by contacting one company that produced the product even if a failure occurs in the stroller function and the cart car function.

Sixth, the present invention can obtain the effect of reducing the weight of the product than when manufacturing a conventional stroller and cart cart separately. When the conventional stroller and cart cart are separately manufactured, there are overlapping configurations such as wheels or handles for each stroller and the cart cart, and these overlapping configurations are a major cause of increasing the weight of the product. However, since the baby carriage according to the present invention shares a configuration overlapping each other in the function of the stroller and the cart, the weight increase may be prevented due to the overlapping application of the configuration.

Seventh, the present invention allows infants who are not interested in the stroller to easily adapt to the stroller through interest and interest in the cart.

Eighth, the present invention can be expected to have a good effect on the behavioral development of the infant, because the infant can be spontaneously acting through the cart, away from the stroller was passively dragged by the parent. After all, the present invention fully reflects the consumer's expectations for the stroller.

Although the present invention has been described in detail using the preferred embodiments, the scope of the present invention is not limited to the specific embodiments, and should be interpreted by the appended claims. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
