Description

[Detailed description of the invention] Industrial application field This invention relates to a folding stroller.
More specifically, it relates to a folding stroller with a removably attached basket.

BACKGROUND OF THE INVENTION Folding strollers are equipped with a basket for storing personal items and shopping. Conventional methods of attaching a basket include hooking parts on the bottom of the basket to both axles that are horizontally mounted on the front and rear leg rods that make up the main body of the stroller, or mounting the basket on the front legs. It was attached by hanging the side of the basket from a swinging rod that was pivotally connected to the rod and the rear leg rod. In this way, all conventional baskets are attached directly or indirectly to the front and rear leg rods, so it is possible to fold and assemble the stroller with the basket attached, but the basket tilts when folded. . That is, it was not possible to fold the stroller with the basket in a horizontal position.

Problems that the invention aims to solve When a conventional stroller with a basket is folded, the basket tilts and the items stored in it fall out, so it was necessary to take out the items each time the stroller was folded. . The present invention was devised to eliminate this drawback, and provides a folding stroller that allows the stroller body to be folded and assembled while the attached basket always remains horizontal without being affected by the assembly or folding of the stroller. This is what we provide.

Means for solving the problem Mounting brackets 28, 28 for attaching the backrest rod 27 to the lower part of the push rod 1 of the foldable and assembleable stroller
and bracket 3 installed slightly above it.
Fixing pins 35, 35 are provided protruding from 4, 34, and the basket 30
The projecting piece is formed into a square shape when viewed from a plane with both sides of the front side retracted and the central part protruding, and the tip is curved in front of the bottom of both sides of the basket 30 to form a square shape. 31, 31 are installed, and the wire rods are bent into a square shape on the upper edges of the left and right sides of the basket 30 to form the grooves 3.
The mounting rods 33, 33 formed with 2, 32 are rotatably mounted, and the grooves 3 of the mounting rods 33, 33
The basket 30 is removably suspended by hooking the 2 and 32 parts on the fixing pins 35 and 35.

Function Since the basket 30 suspended from the fixing pins 35, 35 by the mounting rods 33, 33 is designed to rotate around the fixing pins 35, 35, when the stroller body is assembled, the rear leg rods 4, 4 By this, the protruding pieces 31, 31 fitted thereto are pushed backward and the basket 30
The mounting rods 33, 33 are rotated and pushed up while maintaining the horizontal state. When the main body of the stroller is folded, the protruding pieces 31, 31 are detached from the rear leg rods 4, 4, and the basket 30 is lowered by rotating the mounting rods 33, 33 while maintaining a horizontal state due to the weight of the basket and the contents. do. When the stroller is assembled, the basket 30 is suspended by the mounting rods 33, 33, and the curved tips of the protruding pieces 31, 31 provided at the front of the bottom abut against the rear leg rods 4, so that the basket 30 is level. supported in the form of
When the stroller is folded, the basket 30 is attached to the mounting rod 3
3 and 33, the protruding part of the front side of the basket 30 comes into contact with the hand lever 1, and the recessed part comes into contact with the mounting fittings 28 and 28, so that it is supported horizontally.

Example An embodiment of this invention will be described based on the drawings.

The connecting rods 15, 15 are pivoted about the respective pins that pivotally connect them, and are folded as shown in FIG. Then, when the stroller is folded, the mounting rod 33
The basket 30 is rotated about the fixing pins 35, 35 while holding the basket horizontally due to the weight of the basket 30 and the contents, and the basket 30 is lowered. The lowered cage is attached to the mounting rods 33, 33
When hanging, the protrusion on the front side comes into contact with the hand lever 1, and the retracted both sides are attached to the mounting brackets 28, 28.
It is supported in contact with and stabilized horizontally.

Next, when assembling the stroller, hold the push rod 1 and the armrest rod 2 and pull them outward.
Armrest rod 2 Rear leg rod 4, 4 Front leg rod 8, 8 and connecting rod 1
5 and 15 are rotated about respective pins that connect them, and the locking shafts 25 and 25 engage with the recessed portions 23 and 23, so that they are assembled into the operating state shown in FIG. When the stroller is assembled, the basket 30 is pushed up backward by the rear leg rods 4, 4 while maintaining a horizontal state, and the mounting rods 33, 33 rotate accordingly.
The pushed up basket 30 is suspended by the mounting rods 33, 33 and the protruding pieces 31, 3 attached to the bottom.
The curved tip of 1 is the rear leg rod 4, 4.
It is held stably in a horizontal position by abutting and fitting.

Effects of the invention Fixing pins 35, 35 are provided protruding from the brackets 34, 34 attached to the hand lever 1, and these fixing pins 35,
Since the basket 30 is hung by rotatably hooking the mounting rods 33, 33 on the stroller body 35, the mounting rods 33, 33 rotate as the stroller body is assembled and folded.
As a result, the basket 30 is raised and lowered while always maintaining a horizontal state. When the stroller is assembled, the basket 3
0 is stabilized by maintaining the horizontal state by fitting the curved tips of the protruding pieces 31, 31 attached to the bottom into the rear leg rods 4, 4. Furthermore, when the stroller is folded, the front side of the basket 30 is shaped like a square, so the central protrusion comes into contact with the push rod 1, and the retracted portions on both sides are attached to the mounting brackets 28, 28. It is kept in a horizontal state and stabilized by coming into contact with it. Therefore, with the stroller of the present invention, there is no need to take out and take out the stored items each time it is folded and assembled, unlike conventional strollers with a basket attached, and the stroller can be folded and assembled with the stored items left in the basket. can. Further, the cage 30 can be attached and detached by simply hooking the mounting rods 33, 33 onto the fixing pins 35, 35, so that attachment and detachment is extremely easy.
