Description

Infant Back Carrier {BACKCARRIER FOR INFANT}

The present invention relates to an infant back carrier, and more particularly to an infant back carrier for carrying the infant on the back.

In Korea, when an infant is raised or taken out of the house, the bag is wrapped around the infant. Recently, due to the convenience of carrying the bag instead of the bag, the carrier carrier (Sack) holding the infant in the chest (Sack) and the back frame of the collapsible frame structure that can carry the infant on the back has been used a lot.

Referring to the conventional infant back carrier based on FIG. 1, the main frame 10 is formed by bending two bridges 14 at both rear ends of the handle 12 to face forward. The support frame 20 is rotatably assembled about the hinge shaft 22 so that the main frame 10 can be placed on the floor in the middle of the main frame 10, and the bridge 14 of the main frame 10 is mounted. At the bottom of the reinforcing plate 30 is fixedly coupled. The back carrier has a backpack 40 attached to the mainframe 10. On both sides of the backpack 40, two holes 44 through which both legs of the infant seated in the space 42 pass are formed, and an upper portion of the 'U' shaped tube which can be inserted into the main frame 10 at the top ( 46) is formed. Two front shoulder belts 48 are attached to the front of the backpack 40, the shoulder belt 48 is connected to the band 50 to adjust the length. Band 50 of the shoulder belt 48 is tied to the ring 32 of the reinforcing plate (30).

However, conventional infant back carriers have various problems. First, because the backpack 40 has flexibility, the infant's posture leaning against the back of the backpack 40 becomes uncomfortable. In particular, not only the back of the infant is not supported stably on the back of the backpack 40, but also dangerous, when the infant unfolds the shoulder belt 48, the backpack 40 is pulled forward to limit the behavior. Secondly, even when the support frame 20 is folded with respect to the main frame 10, the width of the vertical direction is not greatly reduced by the protruding length of the handle 12, so that the back carrier may not be easily transported and stored. Third, since the main frame 10 and the support frame 20 must be assembled after the tube 46 of the backpack 40 is inserted into the handle 12 of the main frame 10, the assembly process has been limited. Fourthly, since the tube 46 of the backpack 40 must be inserted from one end of the bridge 14 of the mainframe 10 and placed on the handle 12, considerable time and effort is required to assemble the backpack 40. This took In addition, the backpack 40 could not be separated from the main frame 10 by the assembly structure of the main frame 10 and the support frame 20. Therefore, when washing the soiled backpack 40, the laundry should be washed in a state in which the backpack 40 is attached to the mainframe 10, which is very difficult and difficult to wash.

On the other hand, there is a baby carriage that carries infants or infants past the infant, the baby carriage has the advantage that can move freely to ride the infant. Therefore, the back carrier which can combine the functions of the back carrier and the stroller has been researched, but the back carrier which satisfies this has not been developed.

The present invention is devised to solve various problems of the related art as described above, and an object of the present invention is to provide an infant back carrier for stably supporting the back of an infant.

Another object of the present invention is to provide an infant back carrier that does not restrict infant behavior.

Another object of the present invention is to provide an infant back carrier that is easy to transport and store.

Another object of the present invention is to provide an infant back carrier that is easy to assemble and detach the backpack.

Still another object of the present invention is to provide an infant back carrier having the function of a baby carriage.
