Description

DETAILED DESCRIPTION OF THE INVENTION "Object of the Invention" a Field of Industrial Use The present invention relates to a stroller, which is characterized in that a storage basket is folded in two and folded together with a tiltable backrest pipe.

b The conventional foldable stroller has a structure in which the backrest pipe that is tiltably provided is first folded, and then the basket receiving pipe that suspends and supports the storage basket is folded.

c Problems to be solved by the invention: Folding the backrest pipe, and then folding the basket receiving pipe that suspends and supports the storage basket, requires two movements, and the bottom surface of the storage basket rubs against the ground and is damaged during folding. I was afraid.

"Construction of the device" a Means for solving the problem A pipe for straddling the base end of the basket receiving pipe and the back end of the backrest pipe for suspending and suspending the storage basket at the center of the rear leg rod. The armrest support rod is pivotally attached to the connecting plate coaxially, and the armrest support rod is pivotally attached to the rear end of the armrest rod and the pipe connecting plate. And the cage receiving pipe suspension support member is pivotally attached to the lower portion of the connecting rod below the pivot point of the connecting rod and the center of the basket receiving pipe, and both open ends of the handle pipe of the gate frame. The pipe connecting plate is pivotally attached, and the center part of the handle pipe is detachably attached to the rear end of the armrest rod, and the horizontal band hung on the lower part of the front leg rod and the tension band extending below the front part of the storage basket. , And the rear part of the footrest is pivoted at a position closer to the center than the pivoting position of the front leg rod. At the same time, the footrest support rod that is supported by being locked to the footrest below the pivotal position of the connecting rod is laid horizontally across the front leg rods, and the basket is hung from the basket receiving pipe by suspending the basket. The purpose is to fold the receiving pipe integrally with the backrest pipe and to fold the storage basket compactly in two.

b Action and Example According to the present invention, therefore, when the basket receiving pipe is gripped and lifted during folding, the basket receiving pipe presses the backrest pipe and the backrest pipe cooperates to be folded. At this time, the engagement between the pipe connecting plate pivotally attached to the basket receiving pipe, the backrest pipe, the armrest support rod, and the handle pipe and the rear leg rod is released, and then the front leg rod is pulled toward the rear leg rod side. The rod, the handle pipe, the backrest pipe, and the basket receiving pipe are folded in a substantially upright state. At this time, the storage basket suspended from the basket receiving pipe is folded in two and folded. Thus, when the folding is completed, the front wheel is located directly above the rear wheel which is grounded, and the lower end of the backrest pipe is grounded so that the stroller can be stably stood upright.

An embodiment of the present invention will be described in detail below with reference to the drawings. A basket receiving pipe (2) formed of a gate frame that suspends and supports three sides of an upper opening edge of a rhombus-shaped storage basket (1) is formed. Both open ends of the hood receiving pipe (4) made of a gate frame are pivotally attached to the upper part of the cage receiving pipe (3) made of a frame by pins (5). A pair of pipe connecting plates (8) and (8) provided with recessed groove portions (8a) on the lower surface for releasably straddling the central portions of a pair of rear leg rods (7) and (7) equipped with rear wheels (6). ), The open ends of the basket receiving pipe (2) and the backrest pipe (3) are coaxially and pivotally attached by the pin (9), and the basket receiving pipe (2) is extended between the legs of the backrest pipe (3). The horizontal bar (10), which is pressed by the upper surface of), is placed horizontally. Both ends of the armrest support rod (12) are pivotally attached by pins (13) and (14) across the rear ends of the pair of armrest rods (11) and the respective pipe connecting plates (8), and the armrest support rods (12) are also attached.
Connect the connecting rods (17) (17) to the center (1) and the center of the pair of front leg rods (16) with the front wheels (15) attached (1).
8) Immediately below the position where the connecting rod (17) and the armrest support rod (12) are pivotally connected by the pin (18) and the connecting rod (17) and the cage receiving pipe (2). The basket receiving pipe suspension support members (20) are pivotally attached to the center of the legs with pins (21) and (21) respectively, and the upper ends of the rear leg rods (7) and the front leg rods (16) are attached to the front ends of the armrest rods (11). ) Are pivoted at the upper ends of pins (23) and (24), respectively. The front leg rod (16) and the connecting rod (17) are pivoted to the position where the pins (19) are pivotally attached, and the rear end both sides of the footrest (25) are pivoted to the connecting rods (17) (17) with the pin (26). Wearing it together (17)
And below the pin (19) pivotally attached to the front leg rod (16), between the front leg rods (16) (16), the open ends of the footrest support pipe (27) consisting of a gate frame are connected to the pins (28) ( 28) A hook (25a) pivotally attached to the footrest (25a) and attached to the bottom of the footrest (25).
Hook the horizontal part of the footrest support rod (27) on (25a).
A horizontal bar (39) for stopping the front wheel is laid across the front wheel (15) of the front leg rod (16) and the pedal (39) is attached to the protruding end of the horizontal bar (39).
Secure a) and connect the tension bar (29) to the cross bar (39) and below the front of the basket (1). Rear leg rod (7)
The connecting rods (30) (30) are pivoted by the pins (31) (32) over the rear wheel (6) side and the pipe connecting plate (8), respectively, and both of the handle pipe (33) which is a gate frame. The open end is pivotally attached to the pipe connecting plate (8) with pins (34) (34), and the central portion of the handle pipe (33) is detachably attached to the rear end of the armrest rod (11). The upper and lower surfaces of the connecting rod (17) are provided with recesses (35) and (36), respectively, and the locking rod (37) is laid across the central portion of the rear leg rods (7) and (7). ) The recess (35)
The stroller body is secured to the recess (36) by locking the locking rod (38) which is horizontally engaged with and disengaged from the pipe connecting plate (8) (8). Stable and fixed well,
Further, the upper opening edge of the storage basket (1) is attached to the locking rod (38) and the basket receiving pipe (2).

"Effect of the Invention" Since the present invention is configured in this way, the storage basket (1) can be folded in two compactly by one folding operation. Further, when folded, the lower end of the backrest pipe (3) is in contact with the ground, and the folded stroller is held upright in cooperation with the contact of the rear wheel (6).

As described above, the present invention is a useful device that has a strong structure, is highly durable, and is easy to manufacture.
