Description

The present invention relates to a structure of a stroller, and more particularly to a stroller frame that can freely change the direction of a seat or a seat support frame by a simple operation.

  The stroller is pushed forward by an adult with an infant on it. Since the handle tube of a conventional stroller has a fixed angle, it cannot be rotated to change direction. However, if the infant's feelings are not calm, or the infant's riding condition seems to be unsafe, or if they try to push the stroller while cradling the infant, the direction of the stroller seat changes. There is a need to do that.

  US Pat. No. 5,845,924 discloses a stroller that rotates a handle tube to change the direction of a seat. The stroller is provided with a handle tube rotatably on a frame, selectively positioned by using a slide ring, and the position of the handle tube can be changed forward or toward the publication. Therefore, the person who operates the stroller can select whether to face the infant or advance in the same direction.

However, although the baby stroller described above can meet the need for a baby stroller that can change the direction of the seat, it still has the following drawbacks.
1. It takes a lot of space to rotate when changing the direction of the handle. In addition, when the baby stroller is operated to move and not to change the seat portion, the space becomes narrow and the operation is obviously difficult and inconvenient.
2. When a general baby stroller is pushed and moved, it is configured so that the front wheel can freely change direction so that the direction can be freely changed, but the direction of the rear wheel is fixed. Therefore, the conventional stroller cannot maintain the agility when the direction is changed by rotating the handle tube.
