[Detailed explanation of the idea] This invention relates to a folding baby carriage with a basket.

Having a basket attached to a baby carriage is very convenient when shopping, etc.

Therefore, many baby carriages with baskets have been proposed.

In addition, in the case of a folding stroller, the basket attached to the stroller is folded following the folding motion of the stroller body, and is either stored in the space occupied by the stroller body in the folded state, or is placed far away from the occupied space. It is hoped that it will not protrude.

The basic structure of the folding baby carriage with a basket of this invention has already been filed by the applicant for the utility model registration, and a basket is added to this basic structure.

Regarding the basic structure of the above-mentioned baby carriage body,

Therefore, the main purpose of this invention is to provide a folding baby carriage with a basket, which satisfies the above-mentioned requirements and has a basket attached to the baby carriage main body having the above-mentioned basic structure.

Other objects and features of this invention will become clearer from the detailed description given below with reference to the drawings.

An embodiment of this invention will be described in detail below with reference to the drawings.

Before describing such an embodiment in detail, for convenience of understanding, the structure and operation of the baby carriage body will first be described, and after the description of the baby carriage body, a description of the basket will be given.

First, an overview of the baby carriage body will be described with reference to FIGS. 1A, 1B, and 2.

FIG. 1A is a perspective view of the baby carriage in an open state, FIG. 1B is a right side view thereof, and FIG. 2 is a right side view of the baby carriage in a closed state.

The baby carriage shown here basically consists of a pair of support leg push rod connecting rods 1 and a pair of front legs rotatably supported by a support leg pivot pin 2 at a relatively forward end or approximately in the middle thereof. 3
and a pair of rear legs 4, and a pair of rear legs 4 rotatably supported by a push rod pivot pin 5 at the rear end of the support leg push rod connecting rod 1 at a point separated from the lower end by a predetermined distance. Push rod body 6
, a front leg connecting rod 8 that connects a pair of front legs 3 and can be bent only downward (arrow 7), and a rear leg connecting rod that can be bent only downward (arrow 9) that connects a pair of hind legs 4. It consists of a rod 10 and a press rod connecting member 12 that connects a pair of press rod bodies 6 and is bendable only in the forward direction (arrow 11).

A press rod 13 is formed by the press rod main body 6 and the press rod connecting member 12.

Furthermore, in such a basic structure, the push rod body 6
The lower end and the rear leg 4 are bendably connected by the push rod support angle 14 via pivot pins 15 and 16, so that the push rod support angle 14 is aligned along the upper half of the rear leg 4. The lower end of the push rod body 6 depends on whether it is rotated in the direction of the arrow 17 (FIGS. 1A and 1B) or in the direction of the arrow 17 along the lower half of the hind leg 4 (FIG. 2). Part is hind leg 4
brought to a relatively upper position or brought to a relatively lower position.

When the lower end of the push rod main body 6 is brought to a position relatively above the rear leg 4, the supporting leg push rod connecting rod 1, the lower part of the push rod main body 6, and the upper part of the rear leg 4 are connected. Define the triangle and establish the open position of the stroller.

When the lower end of the push rod main body 6 is brought to a position relatively below the rear leg 4, the supporting leg push rod connecting rod 1 and the push rod main body 6,
The geometry of the associated parts is chosen such that the rear legs 4 are substantially parallel, thereby establishing the folded position of the stroller.

A folding interlocking connecting rod 18 is provided between the push rod support angle 14 and the front leg 3, and a pivot pin 1 is provided at both ends.
5 and 19.

Between the pair of folding interlocking connecting rods 18, the front (arrow 20)
A bendable central connecting rod 21 is connected only to the central connecting rod 21.

In this way, the basic structure of a foldable baby carriage is achieved.

Next, each part will be described in detail.

Figure 3 shows support leg push rod connecting rod 1, front leg 3, and front leg connecting rod 8.
FIG.

4 and 5 are diagrammatic diagrams for explaining the operation of the portion shown in FIG. 3.

Referring to FIGS. 1A to 5, the end of the front leg connecting rod 8 is rotatably supported by a connecting rod rotating tool 23 via a pivot pin 22. As shown in FIGS.

The connecting rod rotating tool 23 includes a socket portion 24 having an inverted U-shaped cross section and surrounding the vicinity of the end of the front leg connecting rod 8 from above.

The connecting rod rotating tool 23 is fitted in the center of the front leg 3 so as to be slidable in the axial direction.

A rod link 25 is connected between the connecting rod rotating tool 23 and the front end of the supporting leg push rod connecting rod 1.

An L-shaped arm 26 is provided that extends inward from the front leg 3 and is pivotally supported by a pivot pin 26a, and the tip of the arm 26 is spaced a predetermined distance from the end of the front leg connecting rod 8. The front leg connecting rod 8 is rotatably supported by the pivot pin 27 located in the position.

In the configuration described above with reference to FIG. 3
Slide the top in the direction of arrow 29.

In response to this, the arm 26 is rotated in the direction of the arrow 26b, and the front leg connecting rod 8 is rotated in the direction of the arrow T about the pivot pin 27 via the pivot pin 22. 8 is bent downward (Fig. 5).

The movement of the front leg connecting rod 8 from the bent state to the opposite state in FIG. 5 is as follows: the supporting leg push rod connecting rod 1 rotates in the opposite direction, and the bar link 25 pushes the connecting rod rotating tool 23 downward. Consisted of.

Due to this force, the front leg connecting rods 8 are rotated so as to extend linearly from the state shown in FIG. 5, and the arms 26 are rotated downward, so that the state shown in FIG. 4 is realized.

A state in which the front leg connecting rod 8 is extended in a straight line as shown in Fig. 4, etc.
In other words, the force that pushes the support leg connection lever 1 downward when the stroller is open (this is generated by the weight of the infant placed on the hammock when the hammock is attached using the support leg push rod connection lever 1, for example) It is the power to be

), the connecting rod rotating tool 23 is forced downward (in the opposite direction of the arrow 29) via the rod link 25, and this causes the front leg connecting device received in the socket portion 24 of the connecting rod rotating tool 23 to move downward. Since the vicinity of the end of the rod 8 is forced downward, the front leg connecting rod 8 is forced to bend upward, and rotation in the direction of arrow 7 is strongly prohibited.

In other words, the more the load is applied, the more firmly the baby carriage is held in the open state.

FIG. 6 is a perspective view of the operatively connected portions of the rear leg connecting rod 10 and the central connecting rod 21, seen from the rear.

7 and 8 are illustrative diagrams for explaining the operation of the portion shown in FIG. 6.

Referring to FIGS. 1A, 1B, 2, and 6 to 8, the central connecting rod 21 is arranged at a different position in the height direction with respect to the rear leg connecting rod 10.

The bending of the central connecting rod 21 in the direction of the arrow 20 is preferably not chosen such that it is bent on a plane containing the pair of folding connecting rods 18, but rather The direction is chosen to point slightly upwards from the containing plane.

This aspect is best illustrated in FIGS. 2 and 8.

A pair of tension rods 30 are provided so that the bending of the central connecting rod 21 in the direction of arrow 20 is linked to the bending of the rear leg connecting rod 10 in the direction of arrow 9.

The tension rod 30 is connected to the bent portion of the rear leg connecting rod 10 and the central connecting rod 2.
Each of the bent portions is connected to a position separated by a predetermined distance.

On the central connecting rod 21 side, in order to connect the tension rod 30,
A tongue piece 33 is provided that projects from the side of a cylinder 32 that is rotatable around a shaft 31.

That is, one end of the tension rod 30 is attached to this tongue piece 33.

In the configuration described above with reference to FIG. 6 etc., the rear leg connecting rod 10 and the central connecting rod 21 approach each other, and the rear leg connecting rod 10 is bent in the direction of arrow 9 (downward), and A pair of folding interlocking connecting rods 18
As the tension rods 30 move closer to each other, the pair of tension rods 30 each rotate in the direction of arrow 34 while bending the central connecting rod 21 in the direction of arrow 20 (forward).

What should be noted here is the rear leg connecting rod 10 and the central connecting rod 2.
1 and the related operation of the tension rod 30.

That is, when the rear leg connecting rod 10 and the central connecting rod 21 approach each other, the tension of the tension rod 30 simply causes the rear leg connecting rod 10 and the central connecting rod 21 to move outward from each other, that is, in the direction of arrow 9. It will be understood that it can be bent in 20 directions.

However, there is another noteworthy action going on here.

That is, each pair of shaft 31, cylinder 32, and tongue piece 33 approaches each other as the central connecting rod 21 is bent in the direction of arrow 20.

This basically means that the tension rod 30 rotates in the direction of the arrow 34, but this rotation of the tension rod 30 increases the distance between the ends defined by the pair of tension rods 30. It means.

If the tension rods 30 were not arranged in a V-shape but parallel to each other, each connection rod 10 would be moved closer to the rear leg connection rod 10 and the center connection rod 21 by the amount that they are closer to each other.
, 21 cannot be bent.

However, since the tension rods 30 are arranged in a V-shape as shown in FIG. It can be seen that the amount of rotation in this direction also contributes to the bending of both connecting rods 10 and 21.

That is, the degree of bending of the rear leg connecting rod 10 and the central connecting rod 21 can be increased, which means that the widthwise dimension of the folding baby carriage can be made smaller in its folded state. be.

Also, what should be noted here is that the mechanism for performing the above operations is extremely simple.

The reverse operation described above is likewise linked by the action of the tension rod 30.

Further, as described above, the configuration in which the bending direction of the central connecting rod 21 is selected to be slightly upward from the plane including the folding interlocking connecting rod 18 is intended to be such that the rear leg connecting rod 10
And at least momentarily during the bending process of the central connecting rod 21, for example, the bending direction of the central connecting rod 21 and the extending direction of the tension rod 30 coincide or almost coincide at times. .

When these directions match, it means that the acting direction of the tension rod 30 and the bending direction of the central connecting rod 21 match, and the force of the tension rod 30 can be efficiently transmitted to the central connecting rod 21. It is.

In this embodiment, the above-mentioned coincidence of directions is achieved when the central connecting rod 21 is in a state substantially close to being bent to the maximum extent.

In other words, it is selected so that it almost closely matches the folded state of the baby carriage.

This is related to the folding operation of the baby carriage, which will be described later.
It may be difficult for the operator to apply more force, or the force may This is because it may require .

That is, when this folding baby carriage is closed, the push rod 13 can be pressed downward toward the ground (arrow 17...FIG. 1A, FIG. 1B), but when it is opened, the push rod 1
3 is lifted and the folding operation proceeds using the baby's own weight.

In this case, the baby carriage has a limit in its own weight and is preferably constructed to be lightweight, so that it is not possible to apply such a large force during the folding operation.

Therefore, as shown in FIGS. 2 and 8, in the initial state from the closed state to the open state, the tension rod 30
It will be understood that if the acting direction of the central connecting rod 21 matches the folding direction of the central connecting rod 21, the central connecting rod 21 can be rotated with a light force.

Also, in the final stage of changing from the open state to the closed state, a relatively large amount of force is required in order to completely achieve the proper alignment of each member as shown in Figure 2. Requires.

It will be understood that even in this case, the configuration of this embodiment is extremely advantageous.

9 to 12 are diagrams for explaining the operating means provided in relation to the push rod 13, in which FIG. 9 is a partially exploded perspective view of the configuration near the operating lever, and FIG. 10 is a partially exploded perspective view of the operating lever. A partially cutaway perspective view of FIG. 11 is taken along the line xt-xt in FIG.
FIG. 12 is a longitudinal sectional view of the structure near the cannula.

A guide socket 73 is formed at the upper end of the press rod body 6.

The end of the push rod connecting member 12 is inserted into the guide socket T3.

The push rod connecting member 12 is made of a round pipe or a round bar, and is rotatable about its axis within the guide socket 73.

A guide elongated hole 74 is formed in the side surface of the guide socket 73 over a substantially perpendicular angular range, and a guide pin 75 fixed to the push rod connecting member 12 is received here.

A bracket 76 is formed on the guide socket 73.
A through hole 7T is formed in the bracket 76.

The operating lever 78 includes a through hole 79.

A shaft (not shown) is inserted with the through hole 79 and the through hole 77 aligned, and the operating lever 78 is inserted into the guide socket 7.
It is rotatably supported with respect to 3.

A recess 80 is formed in the downwardly facing surface of the operating lever 78 .

The upper end of the rod 81 is attached to the portion where the recess 80 is formed, and the lower end of the rod 81 is attached to the cannula 44.

The sleeve 44 is slidably fitted into the lower part of the push rod body 6.

A long hole 45 is provided in the push rod body 6 near where the mantle 44 is arranged.
A pin 46 passing through this elongated hole 45 is inserted into the sleeve 4.
Fixed to 4.

The sliding range of the sleeve tube 44 is defined by the action of the elongated hole 45 and the pin 46.

As shown in FIG. 12, the cannula 44 is always elastically urged downward by a spring 47 inserted between the pins 5 and 46 inside the pipe-shaped push rod body 6. Ru.

Therefore, the lower end surface of the mantle 44 is connected to the push rod support angle 14.
This ensures that the stroller is in the open position (FIGS. 1A and 1B).

The operating lever 78 has the function of separating the sleeve 44 from the push rod support angle 14 and the function of holding the push rod connecting member 12 so as not to rotate relative to the push rod main body 6.

That is, when the operating lever 78 is rotated downward, the guide pin 75 is received in the recess 80 (FIGS. 10 and 11), and the push rod connecting member 12 is rotated relative to the idle socket 73. becomes prohibited.

When the operating lever 78 is rotated in the direction of the arrow 82, the rod 81 is displaced in the direction of the arrow 83, the sleeve 44 is separated from the push rod support angle 14, and the guide pin 75 escapes from the recess 80. , the push rod connecting member 12 is in a state where it can rotate.

At this time, the operating lever 78 is reversed upward beyond the consideration point and is in a stable state.

The rotation of the operating lever 78 in the direction of the arrow 82 is the beginning of a folding operation of the baby carriage, which will be described later.

Then, the downward rotation of the operating lever 78 (this is ultimately urged by the spring 47 mentioned above).

) is realized when fixing the open state of the baby carriage.

FIG. 13 is a perspective view showing a pivot portion of the rear leg connecting rod 10 for the rear leg 4, and FIG. 14 is a front view thereof.

The rear leg connecting rod 10 is rotatably connected via a pivot pin 52 by a U-shaped connector 51 fixed to the rear leg 4.

At the end of the rear leg connecting rod 10, a rotation stopper 53 is formed, which includes a side surface and a surface perpendicular to the rear leg connecting rod 10, so that, as already mentioned, the rear leg connecting rod 10 moves in the direction of the arrow 9.
It is possible to rotate only in the direction.

FIG. 15 is a perspective view showing the pivot portion of the central connecting rod 21 relative to the folding interlocking connecting rod 18, and FIG. 16 is a partially sectional plan view.

The pivot parts shown in these figures are of substantially the same principle as the pivot parts shown in FIGS. 13 and 14.

That is, the central connecting rod 21 is pivotally supported via a pivot pin 55 by a connecting tool 54 fixed to the folding interlocking connecting rod 18, and rotates in the direction of the arrow by a rotation stopper 56 formed at the end of the central connecting rod 21. Only rotation in 20 directions is allowed.

Referring again to FIGS. 1A and 1B, the hammock attached to this baby carriage will be described.

Although the hammock itself is not shown, this hammock is chair-shaped and includes a backrest and a seat.

The backrest portion is held by the backrest holding rod 106, and the seat portion is formed on a plane defined by the folding interlocking connecting rod 18 and the central connecting pusher 21.

The backrest portion is configured to be reclinable, which is achieved by rotation of a backrest holding rod 106 that is pivotally supported on a connector 107 via a pivot pin 108.

The backrest holding rod 106 is configured to be rotated and fixed at a desired position by an operating member 118.

The details of the structure of the main body of the folding baby carriage have been described above.

Next, the folding operation or operation of this baby carriage will be explained.

1A and 1B, in the open state, the press rod support angle 14 is rotated along the upper half of the rear leg 4, so that the lower end of the press rod body 6 is attached to the rear leg. 4. Bring it to a relatively upper position.

At this time, a triangle is defined by the supporting leg push rod connecting rod 1, the lower part of the push rod main body 6, and the upper part of the rear leg 4, thereby establishing the open state of the baby carriage.

Next, the folding operation of this baby carriage from the state shown in FIGS. 1A and 1B to the state shown in FIG. 2 will be explained.

First, the operating lever 78 is rotated in the direction of the arrow 82 (FIG. 10) to turn it upside down.

Since this state is beyond the point of consideration, it is maintained as it is even if it is biased by the spring 47.

At this time, the guide pin 75 escapes from the recess 80, and the push rod connecting member 12 is in a state where it can rotate.

Then, the suppressing engagement state between the sleeve tube 44 and the push rod support angle 14 is released.

The operations described so far can be performed by sequentially operating the two operating levers 78 with one hand.

Next, hold either side of the central bent part of the press rod connecting member 12 with one hand, and while applying a twisting force in the direction of arrow 11, slightly tilt the press rod 13 forward, so that the press rod support angle 14 is After a slight rotation in the direction of arrow 17, the press rod 13 is pushed downward by the hand gripping the press rod connecting member 12 described above.

When this pushing operation is performed, at least the rear wheel 72
is on the ground.

In response to this, the push rod support angle 14 is further rotated in the direction of the arrow 17, and finally the push rod support angle 14 is brought to a position along the lower half of the rear leg 4.

In response, the support leg push rod connecting rod 1 is rotated approximately in the direction of arrow 28 about the support leg pivot pin 2, and the connection rod rotation tool 23 is slid in the direction of arrow 29 via the support link 25.

As a result, the front leg connecting rod 8 is bent in the direction of the arrow 7.

By bending the front leg connecting rod 8 and bending the aforementioned push rod connecting member 12 in the direction of the arrow 11, the widthwise dimension of the baby carriage is reduced.

Therefore, at the same time, the rear leg connecting rod 10 is bent in the direction of arrow 9, and the central connecting rod 21 is bent in the direction of arrow 20 via the tension rod 30.

Further, in accordance with the rotation of the push rod support angle 14 in the direction of the arrow 17, the folding interlocking connecting rod 18 draws the front leg 3 closer to the rear leg 4.

These folding operations proceed almost simultaneously, and eventually the push rod support angle 14 is brought to a position along the lower half of the rear leg 4.

At this time, the front legs 3 and the rear legs 4 are gathered to a position where they are substantially parallel to each other, and the support leg push rod connecting rod 1 is rotated in the direction of arrow 28, so that the rear legs 4 are placed in the internal space of the support leg push rod connection rod 1. is in a state where it is received, and both the support leg push rod connecting rod 1 and the rear leg 4 are brought to substantially parallel positions.

In addition, front leg connecting rod 8, rear leg connecting rod 10, push rod connecting member 1
2, and the central connecting rod 21 is sufficiently bent to form a pair of supporting leg push rod connecting rods 1, front 1% 1lI3, and rear leg 4, respectively.
, press rod body 6, press rod connection member 12, folding interlocking connection rod 18
, and the backrest holding rod 106 are brought close to each other to obtain a folded state in which the seat is also compressed in the width direction.

In this folded state, the two front wheels 71 and the two rear wheels 72 are all brought to the same height, so that they can stand on their own.

In order to change from the folded state shown in FIG. 2 to the unfolded state shown in FIGS. 1A and 1B, basically, the above-described operation can be performed in reverse, and the reverse operation proceeds accordingly.

That is, to put it simply, the press rod support angle 14 is rotated counterclockwise in FIG. 2 via the press rod main body 6 while twisting the press rod connecting member 12 and applying force to spread it. Lift it slightly and pull it toward the back so that it moves.

Accordingly, the push rod support angle 14 is brought along the upper half of the rear leg 4, and the support leg push rod connecting rod 1
is also rotated counterclockwise to bring the front leg connecting rod 8 into a straight state via the rod link 25 and the connecting rod rotating tool 23, and further, the front leg 3 is separated from the rear leg 4 by the folding interlocking connecting rod 18. It will be done.

Then, due to the increase in the dimension in the width direction that has occurred so far, the rear leg connecting rod 10 and the central connecting rod 21 are brought into a straight line state in conjunction with each other by the action of the tension rod 30.

When the state shown in FIGS. 1A and 1B is finally reached, if the operating lever T8 is rotated downward, the guide pin 75 is received in the recess 80 of the operating lever 78.
The bending of the push rod connecting member 12 is prohibited, and the sleeve tube 44 is pressed into engagement with the push rod support angle 14, and the bending of the push rod support angle 14 and the push rod 13 is prevented, A reliable open state of the baby carriage is established.

The structure, operation, etc. of the baby carriage body have been described above.

Next, we will explain the cage, which is a feature of this invention.

FIG. 17 is an illustrative perspective view showing the structure related to the car extracted from FIG. 1A.

The structure related to the car, which will now be explained, is shown in FIG. 1A, FIG. 1B, and FIG. 2 in addition to this FIG. 1T.

The framework of the car will be explained with reference to these drawings.

The frame of the cage is constructed, for example, by appropriately bending a metal rod having an appropriate thickness.

A pivot point 20 spaced a predetermined distance from the lower end of the rear leg 4
1, a pair of mutually independent L-shaped side rods 202 are rotatably supported with a space between them.

This L-shaped side rod 202 has a shape that first extends rearward from the pivot point 201 and then extends upward.

A pair of mutually independent upper side rods 204 are pivotally supported at the upper end of the L-shaped side rod 202 via a pivot point 203 in a spaced-apart manner.

The upper rod 204 extends in the front-rear direction, and its front end is
It is pivoted to the push rod main body 6 via a pivot point 205 .

Note that the pivot points 201 and 205 are connected to the L-shaped side rod 202.
This is achieved by forming a pivot shaft by bending one end of each of the upper rods 204.

The rear ends of the upper rods 204 are bent inward, but are separated from each other.

This is a configuration for allowing the above-described folding operation of the baby carriage body.

The car 206, shown in phantom in FIGS. 1A and 1B, is attached to a framework of L-shaped side bars 202 and top bars 204.

More specifically, the basket 206 is formed into a box shape with an opening at the top, and a thick cloth is placed along each side of the box shape to maintain the overall shape. The surface is made of net fabric.

Therefore, the cage 206 has flexibility.

This allows the folding operation of the stroller body and the basket 206.
This is to allow its own folding operation.

In order to hold the bottom surface of the car 206 and adjust the form of the car 206, a pedestal 20 extends rearward from the rear leg connecting rod 10.
7 is provided.

This pedestal 207 works advantageously especially when a relatively heavy load is stored in the basket 206.

The folding operation of the basket 206 will be explained in relation to the folding operation of the baby carriage body.

When the stroller body is folded, the push rod support angle 14
rolls in the direction of arrow 1T and is brought to a position along the lower half of the rear leg 4.

If you pay attention to this operation, you will understand that the distance between the pivot point 201 and the pivot point 205 becomes narrower.

In response to this, the upper rod 204 rotates counterclockwise about the pivot point 203, as best seen by comparing FIG. 1B and FIG. Side beam 2
02 toward the push rod body 6.

In this state, as is clear from FIG. 2, the stroller body hardly protrudes from the space occupied by the stroller body in the folded state.

Further, in the folding operation of the baby carriage body, the pair of push rod bodies 6 and the pair of rear legs 4 approach each other so that their widths are reduced.

This operation is not impeded by structures associated with the car 206 because the pair of upper rods 204 are separated.

Further, the pedestal 207 is displaced along with the rear leg connecting rod 10,
It is brought to the position shown in FIG. 2, and hardly protrudes from the space occupied by the stroller body in the folded state.

Note that since the car 206 is configured to be flexible, it will advantageously follow the movement or displacement of the L-shaped side rods 202 and the upper side rods 204 and will be deformed as appropriate.

As described above, according to this invention, a folding baby carriage with a basket is provided with a basket that advantageously follows the folding movement of the folding baby carriage body and hardly protrudes from the occupied space in the folded state. is obtained.
