Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to a baby carriage.

[Conventional technology]

For basket-type baby carriages used for infants who cannot sit upright, as in Japanese Patent Publication No. 56-20223, after loosening the nut plate, lower the cylindrical body to the lower end of the rear legs and move the tilting rod in the opening direction. Further, the tilting rod is rotated so that the tip thereof is raised, and after confirming that the tilting rod is horizontal, the nut plate is tightened.

Next, place the basket on the tilting rod and
The holding pieces attached to both sides of the lower surface of the basket are fitted into and engaged with the swinging rod.

After disengaging the holding piece and removing the basket, loosen the nut plate and move the tilting rod in the closing direction while raising the cylinder, and turn the swinging rod so that the tip descends with the tilting rod. Then, after tightening the nut plate, attach the hammock.

[Problem that the invention attempts to solve]

When attaching the basket, the nut plate is loosened, the cylindrical body is slid, the swinging rod is rotated to a horizontal position, and then the nut plate is tightened, which is a time-consuming problem.

Furthermore, since the stroller frame is provided with a cylindrical body having a nut plate, a tilting rod, and a swinging plate, the structure becomes complicated, which causes a problem of an increase in price.

[Means for solving problems]

In order to solve the above problems, this invention consists of a stroller frame that can be folded into a cane shape and a basket, and both ends of U-shaped leg rods are rotatably attached to the middle of both sides of the bottom surface of the basket. Further, an engagement device is provided at both ends of the horizontal portion of the leg rod to removably engage with the front leg rod side ends of both rod members of the horizontal X-shaped connecting member that connects the front and rear leg rods of the stroller frame. One end of the horizontal member is rotatably attached to one of the side lever side ends of both rod members of the vertical X-shaped connecting member that connects the rear leg rod and both side rods of the stroller frame, and a horizontal member is attached to the remaining one side. Providing a cylindrical body through which the other end of the member can slide freely,
An engaging device is provided for detachably engaging the horizontal member at the rear edge of the lower surface of the basket.

[Effect]

When installing the basket, first remove the seat and backrest from the stroller frame.

Next, the leg rod of the basket is tilted downward, and the engaging device of the leg rod is engaged with both rod members of the horizontal X-shaped connecting member, and the trailing edge engaging device of the basket is engaged with the horizontal member. .

〔Example〕

In the figure, A is a stroller frame that can be folded into a cane shape.

The above baby carriage frame A has one front wheel at the bottom end as shown in the illustration.
2 left and right front leg rods 2, a side rod 4 whose lower end is connected to the upper end of the front leg rod 2 via a pin 3, and which can be folded in two from a straight extended state, and an upper end of this side rod 4. The grip 5 provided at Two rod members 10, 10 whose parts are rotatably connected by a pin 9, and a pin 11 which rotatably attaches both ends of the rod members 10, 10 to the middle of the front leg rod 2, the rear leg rod 8, and the lower part. A horizontal connecting member 12 consisting of a horizontal connecting member 12, two rod members 14, 14 which intersect in an X shape and are rotatably connected at the intersection with a pin 13, and the upper part of the side rod 4 and the rear leg rod 8. A vertical connecting member 16 consisting of a pin 15 rotatably connecting both ends of the rod members 14, 14 to the lower part of the vertical connecting member 16.
and a support rod 18 which is rotatably attached at both ends to the upper part of the front leg rod 2 and above the pin 11 of the rear leg rod 8 via a pin 17.

Although not shown, between the lower parts of both rear leg levers 8, there is a link whose outer end is rotatably supported on both rear leg levers, and a link whose inner ends are rotatably connected to each other. In addition, there is provided a spacing positioning device that maintains the spread state of both rear leg levers by causing the connecting portion at the inner end to be lower than the outer end when the pedal is depressed.

B is a basket, and U-shaped leg rods 20 are attached via pins 19 to the middle of both sides of the bottom surface of the basket B.
Both ends are rotatably attached.

In addition, connecting members 12 are provided at both ends of the horizontal portion of the leg rod 20.
An engagement device 21 is provided which detachably engages with the rod material 10 of.

Although the above-mentioned engagement device 21 uses a C-shaped fitting member that is fitted into the rod material 10 from above as shown in FIG. 5, other structures may be used.

Further, one end of the horizontal member 22 is rotatably attached to one of the upper parts of the rod members 14, 14 of the vertical connecting member 16, and a cylinder 23 through which the other end of the horizontal member 22 slidably passes is attached to the remaining one. establish.

Furthermore, an engagement device 25 is provided on the rear edge of the lower surface of the basket B to engage the horizontal member 22 in a detachable manner.

In the illustrated case, the above-mentioned engagement device 25 fixes a seat plate 26 to the lower surface of the basket B, and
While rotating the holding piece 27 rotatably attached to the horizontal member 22, the holding piece 27 is rotated.
However, other structures may be used.

As shown in the figure, a C-shaped clip 28 is provided at the rear of the bottom surface of the basket B.
By fitting and supporting the horizontal part of the leg rod 20 into the basket B, the leg rod 20 can be stacked on the bottom surface of the basket B and stored in a low-volume manner.

The baby carriage according to this invention has the above configuration, and when using the basket B, first the baby carriage frame A is
Remove the seat and backrest sheet (not shown) from.

Next, after tilting the leg rod 20 downward, the engaging device 21 is engaged with the rod material 10 of the horizontal connecting member 12, and the engaging device 25 is engaged with the horizontal member 22 to support the basket B. let

〔effect〕

As described above, according to the baby carriage according to the invention, the basket is assembled by engaging the leg rod engagement device with the rod of the horizontal connecting member of the baby carriage frame and engaging the trailing edge engagement device of the basket with the horizontal member. Since it is designed to be attached, the stroller frame of a conventional baby carriage can be used.

In addition, the engagement horizontal part of the engagement device has one end rotatably attached to one of the vertically connected rods, and the other end slidably penetrates the cylindrical body attached to the other rod. There is no problem in folding the stroller frame into a cane shape.

Furthermore, since the leg rods are rotatably attached to the bottom surface of the basket, the bulk of the basket can be reduced by stacking the leg rods on the bottom surface of the basket when the basket is stored.
