Description

[Detailed Description of the Invention] Hyo Hyo Yu relates to baby carriages, and in particular to a folding mechanism that is adopted as a part of a baby carriage of the type TFF to realize a smooth folding operation.

Transport and operate the baby carriage by considering the overall shape of the baby carriage. Due to its function, the push member for hand-pushing is naturally placed at the top of the baby carriage, so the upper end of this push member is the overall height of the baby. Determine the dimensions.

Therefore, it is desirable to reduce the height dimension in order to reduce the bulkiness of the foldable baby (7) when the push member is closed. A folding baby carriage configured to be carried over a relatively lower bar has already been proposed.

In the seventh example, the pushing member is connected to the longitudinal midsection 9 of the rear leg via a support angle.

One end of the support angle ζ is rotatably connected to the rear leg, and the lower end of the push member 9 is rotatably connected to the other end.

Since the rear legs are arranged to extend substantially in the vertical direction, the open position of this stroller is achieved with the support angle along the upper half of the rear legs, and the support angle is along the upper half of the rear legs. The closed position is realized by rotating and following the lower half of the hind legs.

In this closed state, the support angle is along the lower half of the rear leg, so the push member or relatively lower device must be provided with that much support, which increases the overall height of the stroller. will be reduced.

With the above-mentioned type of baby carriage, in addition to the above-mentioned configuration,
Some devices have a configuration in which the width dimension is also reduced in the closed state.

In this case, many baby carriages are provided with a member that connects the respective members arranged symmetrically, and this connecting member is often configured to be bendable.

For example, it is a connecting member arranged to support the seat of a baby carriage.

Due to the above-mentioned requirements for the folding structure of the baby carriage, it is desired that the rotational movement of the support angle and the bending movement of the connecting member connecting the left and right sides are linked.

Therefore, the main purpose of this invention is to provide a baby carriage with a folding rock structure that can meet the above-mentioned requirements.

Other objects and features of the invention will become more apparent from the detailed description given below with reference to the fixed fit.

On the 1st side of the 1st side, there is a guide pin 133 fixed to the 102 narrow guide hole 3. is accepted.

A bracket 134 is formed in the guide socket 131, and a through hole 135 is formed in the bracket 134.

The operating lever 136 includes a through hole 137.

When the through hole 131 and the through hole 135 are aligned, the shaft 1
39 (Figs. 1 to 3) is inserted, and the operating lever 136
is rotatably supported by the guide socket 131.

The operating lever 136 has a recess 138 on its downwardly facing surface.
is formed.

Therefore, when the operating lever 136 is rotated downward, the recess 138
The guide pin 133 is received inside, and the grip portion 102 is in a state in which rotation with respect to the push member body 104 is prohibited.

On the other hand, when the operating lever 136 is rotated upward, the guide pin 133 escapes from the recess 138 and the guide pin 133
3 becomes movable within the guide elongated hole 132, and the grip portion 102 becomes rotatable relative to the push member main body 104.

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

In the open state of the baby carriage, the support angle 11γ is
The push member body 104 is rotated upward relative to the pivot pin 118 of the rear leg 112, and is along the upper half of the rear leg 112, bringing the push member main body 104 to a relatively upper position. ing.

In this state, a triangle is formed between the lower part of the push member main body 104, the upper part of the rear leg 112, and the rear part of the folding interlocking connecting rod 120, and an open state is established.

To change from the open state to the closed state as described above, the operating lever 136 is rotated upward so that the grip portion 102 can be bent in the direction of the arrow 103.

Next, hold the grip part 102 with one hand, and while keeping the rear wheel 116 on the ground, tilt the entire baby carriage backward so as to lift the front wheel 111.

Accordingly, the weight of the baby carriage acts advantageously to cause the grip portion 102 to bend in the direction of the arrow 103, and
Rotate the support angle 117 in the direction of arrow 129.

At the initial stage of rotation, this support angle 117 does not cause the central connecting rod 204, which can be bent only in one direction, to bend because the rod 161 has a force that pulls it backward. , the support angle 117 acts in a direction to bring the rear leg 112 closer to the front leg 107.

When such an operation has progressed to a certain extent, the pushing member 101 is pushed downward while keeping the rear wheel 116 on the ground.

In response to this, the slider 105 and the push member main body 104 slide, and the support angle 117 comes into a state along the lower half of the rear leg 112, bringing the push member 101 to a lower position.

In response to this, the folding interlocking connecting rod 120 is tilted so that its front end faces upward, and the front leg connecting rod 108 is folded in the direction of the arrow 201 according to the operation described with reference to FIGS. 4 to 6. Can be bent.

According to the bending of this front leg connecting rod 108, a pair of front legs 10
7,107 will be closer to each other.

Also, at almost the same time, the aforementioned slider 105 and the pushing member main body 104 are sliding, so the pair of cross rods 125, 125 are rotated so that they are vertically lined up. The push member bodies 104, 104 and the l pair of rear legs 112, 112 move toward each other, respectively.

At the end of the rotation of the support angle 111 in the direction of arrow 129, the rear leg 112 is sufficiently close to the front leg 107, so that the rod 161 protrudes the central connecting rod 204 and rotates it in the direction of arrow 205. fold it.

This causes the pair of folding interlocking connecting rods 120, 120 to approach each other.

Eventually, as shown in FIG. 3, the front legs 107 are aligned substantially parallel to the pusher body 104, and the rear legs 112 are also aligned substantially parallel to the pusher body 104. , the left and right members become close to each other.

In the state shown in FIG. 3, the front wheel 111 of the 21st-row and the rear wheel 116 of the 21st-row are brought to almost the same height, so this baby carriage can stand on its own in the closed state.

To change the stroller from the closed state to the open state, hold the grip portion 102 of the push member 101 and float the entire baby carriage in the air.

In response to this, the weight of the baby carriage acts and the support angle 11
7 rotates the pivot pin 119 upwardly and downwardly toward the lower end of the push member body 104.

In response to this rotation, the rear leg 112 rotates in a direction away from the front leg 107, and the rod 161 pulls the bent central connecting rod 204 rearward and acts to straighten it.

At the same time, the slider 105 slides downward on the push member main body 104, and the folding interlocking connecting rod 120 rotates so as to be in a substantially horizontal state.

In response to this, the front leg connecting rod 108 is in a state of being extended left and right.

According to such a movement, a pair of front legs 107.1071
Pair of hind legs 112.112, , , , , . 1 pair of push member bodies 104.
20°120, respectively, are separated from each other.

At the end of such operation, the open state shown in FIGS. 1 and 2 is then established.

Here, if the operating lever 136 is rotated downward, this open state is maintained.
