Abstract

The present invention relates to a stroller folded on one shaft, comprising: a frame body (100) including left/right front leg frames (101) to support a front wheel (101a), a horizontal frame (101) connected to a lower part between the left/right front leg frames (101), left/right rear leg frames (102) to support a rear wheel (102a), and a horizontal frame (102) connected to a lower part between the left/right rear leg frames (102); a seat frame (200) supported to the frame body (100) through a shaft (103); a safeguard frame (300) and a backrest frame (400); a handle frame (500) having a horizontal frame (503) attached through a slider (502) to be able to slide with respect to a tubular body (501) connected to the shaft (103); and canopy frames (600, 600) installed in the backrest frame (400) to shield sunlight. Accordingly, provided are advantages of superposing all frames, such as the seat frame, the safeguard frame, the canopy frame, the handle frame, the backrest frame, etc., on one shaft to realize compact folding capable of maintaining strength while simplifying the frame; providing excellent economic efficiency due to a low price of a product while being stably used for a long term without failure as well as being lightweight due to a small number of parts; and capable of enhancing controllability or driving stability in accordance with a situation of a road surface where the stroller is moved and also providing a beautiful appearance of not only wheels but an overall stroller.

Description

Stroller folded into one axis < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a stroller, and more particularly, to a stroller folded into a single convenient shaft for folding into a single shaft when the stroller is lifted.

BACKGROUND ART [0002] Conventionally, a baby carriage for riding an infant is widely available. There are various demands on the stroller according to its use. For example, in order to safely ride an infant, the stroller is required to have high rigidity and stability during driving. In addition, it is desired that a small rotation is possible so that a complicated path can smoothly proceed, but the ease of maneuvering is desired. It is also desired that the stroller can be folded in consideration of the storage space when not in use, and that the stroller be made smaller. In addition, when the stroller is a folding type, ease of folding operation is also desired. Various baby carriages have been proposed to satisfy such demands (for example, see Japanese Patent Laid-Open No. 2007-537911, Patent Document 1).

However, meeting such a variety of demands simultaneously can also be a case where a configuration opposite to that of a baby carriage is required. For example, if a stiffness is given to the stroller, the stroller becomes large in size, resulting in inconvenience in storage and the like. Because of this, the variety of stroller that has been proposed so far does not satisfy each of the various demands simultaneously at a sufficient level.

In addition, in general, in the baby carriage used when the baby carriage is taken outdoors for walking or shopping, the baby carriage can be easily folded, stored or carried as needed, and the manual lever of the baby carriage can be pushed ) State or a state in which the user faces a pushing state in which the user faces the infant, has been variously proposed and put into practical use.

However, in order to make the manual lever of the stroller to be in the rear surface state or in the face-to-face state, the manual lever of the stroller is simply pivoted in the front-back direction of the seat back. In this case, however, the stroller can not be folded in two- It is impossible to make the stroller sufficiently small.

A "stroller" of Japanese Patent No. 0852409, which has been developed in the prior art in view of the above-described circumstances, is disclosed in the patent document 2 (see Patent Document 2).

1, the stroller includes a pair of left and right front legs 12 having front wheels 11, a pair of left and right rear legs 14 having rear wheels 13, A left and a right pair of armrests 16 and two right and left pipes 17 pivotally mounted on one end of each armrest 16 and extending parallel to each other, A front leg 12 is pivotally mounted on the other end of each of the armrests 16. A guard arm 18 which can be bent in an arcuate form is detachably mounted between the front ends of the left and right armrests 16, The left and right front legs 12 are connected by a front connecting bar 20 having a foot plate 19 and the left and right rear legs 14 are connected by a rear connecting And the connecting bar 22 is connected to the middle portion of each of the front legs 12. [ And a rear end of the connecting bar 22 is pivotally mounted on a hind leg supporting member 23 fixed to the lower portion of the pipe 17 and the left and right connecting bars 22 Are connected by an upper connecting bar 24. The front legs 12 having these front wheels 11, the rear legs 14 having the rear wheels 13, the armrests 16, the pipes 17, And the manual lever 15 is attached to the baby carriage body 10 so as to be swingable. The baby carriage main body 10 is foldably folded in three folds, and the U- Since the lever is mounted so that it can be pivoted back and forth, it can be used both as face type and back type at the time of use, and it can be folded and folded in three folds and has a feature that can be carried.

However, as shown in Figs. 2 to 4, the "stroller" of Patent No. 0852409 has a problem in that the number of frames is increased by a plurality of folding shafts and the casting is complicated and the weight is increased.
