Problems solved by technology

[0005] In conventional strollers, when the body is turned or changed direction with a child on it, the force that should be applied to the handle increases, and the body may not turn smoothly when the handle is held with one hand.
On the contrary, even if it is to be operated with one hand, since the operation part is provided in the center of the handle, it is difficult to hold it, so that a sufficient force cannot be applied to the handle.

[0097] figure 1 It is a perspective view of the stroller of the first embodiment of the present invention. First, the overall structure of the stroller 1 will be described. The stroller 1 includes a body 2 and a seat 3 supported by the body 2 . Body 2 has front foot 4, a pair of rear foot ( figure 1 Among them, only one side is shown) 5, a pair of armrests 6, a pair of seat frames 7, and push frames 8. The front foot 4 has a pair of front foot frames 9 . The front leg frames 9 are formed using hollow pipes, and their lower ends converge at the center in the left-right direction (sometimes referred to as the vehicle width direction) of the vehicle body 2, and the front wheels 10 are attached to the lower ends. Rear wheels 11 are attached to respective lower ends of the rear legs 5 . The front wheel 10 has a structure in which a pair of tires 10a are coaxially connected by an axle 10b. The distance between the tires 10 a in the axle direction is much smaller than the dista...

[0150] Figure 51 It is a side view of the baby carriage provided with the lock mechanism of 2nd Embodiment of this invention. The stroller 201 includes a body 202 . The vehicle body 202 has a link mechanism mainly composed of a front leg 203 , a rear leg 204 , an armrest 205 , a seat frame 206 , and a push frame 207 . By rotating the link members constituting the link mechanism around their joint points, the vehicle body 202 can be in use ( Figure 51 state shown) and the collapsed state. in addition, Figure 51 The structure on one side in the left-right direction (width direction) of the vehicle body 202 is shown, and the opposite side also has the same structure. The left and right front legs 203 are connected by appropriate connecting members (not shown). The same is true for the rear foot 204 . Front wheels 208 and rear wheels 209 are attached to respective lower ends of the front legs 203 and the rear legs 204 .

Abstract

The invention provides a baby carriage with increased stability and operationality. The distance of the front and rear direction between the front-wheel (10) and back-wheel (11) viewed from the width direction is set as Xa and the distance of the front and rear direction between the back seat crossing point (Ci) of the seat (3) and the back wheel axle shaft is set as Xb and the distance of the front and rear direction between the center (Cg) of the handle part (17b) of the handle (17) for operation of hand pushing and back wheel axle shaft (Aw) is set as Xc, and the height of the back seat crossing point (Ci) is set as Za and the height of the center (Cg) of the handle part (17b) is set as Zb wherein the Xa is less than 2Xc and the Xb is among 0.4-0.6Xc and the Za is less than 0.32Zb.

Description

technical field [0001] The present invention relates to a baby carriage which improves the stability and operability during operation of the body, especially during turning operation, and a locking mechanism of the baby carriage with a foldable body. Background technique [0002] There is known a stroller which has an inverted U-shaped hand push frame for pushing and operating the body of the body by hand, and operating components such as a folding mechanism for the body are arranged in the center of the upper end of the hand push frame (for example, refer to the patent document 1). However, the influence of vehicle body size, such as the relationship between the seating position of an infant and the handle position, on the operability, stability, and the like of the vehicle body has not been sufficiently studied. [0003] In addition, there is provided a stroller in which a body can be deformed between a use state and a folded state by operating a link mechanism of the bod...
