Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a baby carriage in which an auxiliary seat for an infant placed on a car seat is attached to the baby carriage frame.

[Conventional technology and its problems]

When an infant is placed in a car, the infant is placed in an auxiliary seat installed in the car seat.

Also, when dropping off the infant, the baby is unloaded from the car and the baby is placed on the stroller.

If such a system is adopted, the auxiliary seat and the baby carriage must be purchased separately, resulting in a large expense.

Furthermore, since both the baby carriage and the auxiliary seat are stored when they are not needed, there is a problem in that a large space is required.

Therefore, as shown in Japanese Utility Model Application Publication No. 55-144166, there is a handcart in which an infant basket can be removably placed on an auxiliary frame.

According to the above-mentioned handcart, since the grip of the main frame for pushing the handcart faces backward, there is a problem in that the face of the infant placed in the basket does not face the face of the parent.

Therefore, this invention allows the handle frame to be rotated back and forth to change its orientation.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention has developed a baby carriage frame consisting of a receiving frame with a handle frame, front wheels and rear wheels provided on both sides of the receiving frame, and a car seat and the above-mentioned receiving frame. In a stroller comprising an auxiliary seat for an infant that can be placed on a frame, and an attachment device provided to removably attach the auxiliary seat placed on the frame, handle frames are provided on both sides of the frame. The lower ends of both sides are rotatably attached so that the handle can move in the front-rear direction, one end of the first link is rotatably attached to the receiving frame, and one end of the second link is rotatably attached to the handle frame. The other end of the first link and the other end of the second link are rotatably connected via a pin, protruding from one of the first and second links to allow the first and second links to rotate around the pin. It is equipped with a protrusion that regulates the

[Effect]

When the handle frame is tilted backward, the first link and the second link are folded in a folded state, and the other end connecting parts of the first and second links are depressed downward, so that the handle frame tilted backward is stopped at a fixed position.

Further, when the handle frame is tilted forward, the first link and the second link are extended into a straight line, and the projecting piece protruding from one of the first and second links is It touches and maintains an extended straight state.

As a result, the handle frame, which is tilted forward, stops in a fixed position.
