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] Fig. 1 is a perspective view of a stroller according to a 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 . The body 2 has a front leg 4 , a pair of rear legs (only one side is shown in FIG. 1 ) 5 , a pair of armrests 6 , a pair of seat frames 7 , and a push frame 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 distan...

[0150] Fig. 51 is a side view of the stroller provided with the lock mechanism according to the second embodiment of the present 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 . The vehicle body 202 can be deformed between the use state (the state shown in FIG. 51 ) and the folded state by rotating the link members constituting the link mechanism around respective connection points. In addition, FIG. 51 has shown the structure of the side of the left-right direction (width direction) of the vehicle body 202, 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, which improves the stability and operability of the vehicle body during operation. When the distance between the front wheel (10) and the rear wheel (11) in the front-rear direction when viewing the vehicle body from the vehicle width direction is Xa, the distance between the back seat intersection (Ci) of the seat (3) and the axis of the rear wheel is The distance in the direction is set as Xb, the center (Cg) of the handle portion (17b) of the handle (17) used for hand-push operation and the distance in the front and rear direction of the rear wheel axis (Aw) are set as Xc, and the intersection of the back seat ( When the height of Ci) is Za and the height of the center (Cg) of the handle (17b) is Zb, the distance Xa is set to be less than 2Xc, the distance Xb is set to a range of 0.4Xc to 0.6Xc, and The height Za is set to be 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...
