Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a folding stroller that can be self-supporting when folded and improves usability.
[0002]
[Prior art]
Conventionally, three types of baby stroller folding structures are known. By the way, since a stroller having a structure in which the front wheel is lifted upward by folding, it is difficult to be self-supported in the folded state, so that a stand with a form that springs up by a spring has been conventionally known.
[0003]
[Problems to be solved by the invention]
However, the conventional stand has to be operated at the time of folding or protrudes to the side of the support leg, and thus has a disadvantage that it is not easy to use.
[0004]
The present invention solves the above-mentioned drawbacks, and is intended to provide a folding stroller equipped with a self-supporting device that is easy to use without being greatly protruded even when it is automatically foldable.
[0005]
[Means for Solving the Problems]
For this purpose, the folding baby stroller of the present invention supports a wheel that is grounded when folded so that the wheel can be moved up and down along the supporting leg on one side of the supporting leg that is rotatably provided at the tip part, A grounding piece is horizontally extended at the lower end of the support, and the upper end of the support is connected via a link to the lower end of the handle shaft extending downward from the bending fulcrum of the support leg. The support piece is pushed down by the link, so that the grounding piece is arranged substantially at the same height as the wheel.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. 1 is a perspective view when the stroller according to the present invention is used, FIG. 2 is a perspective view when the stroller is folded, FIG. 3 is a front view thereof, and FIG. 4 is a side view thereof. The stroller shown in this embodiment has a pair of rod-shaped handle shafts 1 and 1 having an upper end formed in a J-shape, and a pair of support legs 3 each having a rear wheel 2 and 2 rotatably provided at the tip. , 3, a pair of support legs 5, 5 having front wheels 4, 4 rotatably provided at the front end portions, and a seat portion seat 6 are main constituent members. The upper ends of the support legs 3 and 3 are connected to a connecting tool 8 fixed by a pin 7 near the lower end of the handle shafts 1 and 1 via a pin 9 so as to be refractably connected. Further, a connecting tool 11 is pivotally attached to the lower ends of the handle shafts 1, 1 via pins 10, and the upper ends of the support legs 5, 5 are fixed to the connecting tools 11 by pins 12. 13 is an openable and closable X-shaped frame stretched between the upper end of the handle shafts 1 and 1 and the substantially intermediate part of the support legs 3 and 3, and 14 is an approximately intermediate part of the support legs 3 and 3 and the support legs 5 and 5. It is an X-shaped frame that can be freely opened and closed and is stretched between the substantially middle part of the frame. The seat 6 is constructed between the handle shafts 1 and 1 and the support legs 5 and 5. Reference numeral 15 denotes a horizontal tension rod composed of two refractable members that are installed between substantially the middle portions of the support legs 3 and 3. Reference numeral 16 denotes a flexible footrest band constructed between the support legs 5 and 5.
[0007]
In this stroller, bearings 20 and 20 are fixed to one side of one rear supporting leg 3 with a pin 25 at an appropriate interval, and a square bar-shaped supporting rod 21 is formed along the supporting leg 3 by the bearing tool. The support piece 21 is supported so as to be movable up and down, and a grounding piece 22 is horizontally extended at the lower end portion of the support 21, and a link 24 is pivotally attached to the upper end of the support 21 with a pin 23. The other end of the link is pivotally attached to the pin 12 of the connecting tool 11 provided at the lower end of the handle shaft 1.
[0008]
In the stroller configured as described above, since the support 21 is supported by the link 24 in the use state shown in FIG. 1, the grounding piece 22 is located away from the ground and inward, and the support 21 Is supported so as to be able to advance and retreat along the support leg 3, so that these mechanisms do not interfere with traveling. Then, the horizontal tension rod 15 is refracted upward, and the support legs 5 and 5 are flipped upward with the pin 10 as a fulcrum, and the support legs 3 and 3 are swung forward with the pin 9 as a fulcrum and are substantially the same as the handle shafts 1 and 1. 2 to 4, the pin 23 is pushed against the link 24, so that the support 21 is pushed down and the grounding piece 22 is approximately the same height as the wheels 2 and 2. As a result, the wheels 2 and 2 and the grounding piece 22 are appropriately spanned so that they can stand on their own.
[0009]
In the stroller of the present invention, the link 24 is thus connected to the lower end portion of the handle shaft 1 extending downward from the bending fulcrum of the support leg 3, so that the lower end portion of the handle shaft 1 is relatively lower when folded. Therefore, the support 21 is pushed down naturally, and the grounding piece 22 automatically comes to ground. For this reason, the present invention is not limited to the stroller having the folding structure shown in this embodiment. In other words, if the lower end portion of the handle shaft is connected so as to press the link at the time of folding, the other folding structure conventionally known is used. It can also be applied to strollers.
[0010]
【The invention's effect】
As described above, the stroller according to the present invention supports the supporting rod on one side of the supporting leg that is rotatably provided at the tip portion of the wheel that is grounded at the time of folding so as to be movable up and down along the supporting leg. A grounding piece is horizontally extended at the lower end of the support, and the upper end of the support is connected via a link to the lower end of the handle shaft extending downward from the bending fulcrum of the support leg. Since the support piece is pushed down by the link, the grounding piece is arranged so as to be almost at the same height as the wheel. Therefore, it is possible to automatically stand up by simply folding it without any operation, improving usability. At the same time, the mechanism can be configured compactly without protruding greatly from the side of the support leg, and therefore has a remarkable effect such as not disturbing during normal driving.
