Abstract

PURPOSE:To prevent the negligence of a locking operation by applying the constitution wherein a switch is turned off to give a locked condition when the first and second members are engaged with each other, and the switch is turned on to allowing the operation of an operation mechanism and output a signal when the aforesaid members are not engaged with each other. CONSTITUTION:When the operation button 24 of a push rod connection member 11 is moved up, a pair of rotary members 22 and 23 rotate in respective directions opposite to each other, while pullin wires 37 and 39. A lock member for maintaining an open condition and a reversing bracket are thereby disengaged from each other and the open lock condition of a baby carriage is released. In this releasing process, a stopper 40 is moved right and the engagement claw 42 thereof projected down is faced to the recessed part 29 of the operation button 24, and the motion thereof is prevented with the projected part 28 of the button 24. The released condition is thereby maintained and a sound generation device 50 is actuated. On the other hand, when the operation button 24 is moved down and the stopper 40 is moved left, the baby carriage turns into an open condition. As a result, the engagement claw 42 comes in contact with the projected part 28 for locking the baby carriage in an open condition, and no sound is generated by the sound generation device 50. According to the aforesaid construction, the proper locking of the baby carriage can be ensured.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a baby carriage, and in particular, an operating mechanism that performs a desired operation by a predetermined operation, and a locking device that can prohibit the operation of this operating mechanism. The present invention relates to a baby carriage equipped with the following.

[Prior art] As an interesting prior art for this invention, the Japanese Patent Publication No. 58
There are baby carriages disclosed in Japanese Patent Publication No.-32065 and Japanese Patent Publication No. 62-13230. The baby carriages disclosed in these publications are equipped with a pair of reversible brackets. Each of the pair of reversible brackets is rotatably connected at one end at the center of the pair of hind legs, so that it can be moved freely along the upper or lower half of the hind legs. It is provided. In the open state of the baby carriage, the inversion bracket is fixed at a position along the upper half of the rear legs, thereby locking the open state of the baby carriage.

A cannula is provided which can engage the inversion bracket to secure the inversion bracket. Further, a pair of operating levers are provided on a pair of push rods located on the left and right sides of the baby carriage. The operating lever and the cannula are connected by a wire. Therefore, when the mantle is moved by operating the pair of operating levers provided on the left and right push rods, the state of engagement between the mantle and the reversal bracket is released, and the reversal bracket is in a state where it can be transferred. . In other words, the open state of the baby carriage is unlocked.

Furthermore, another example of prior art that is of interest to the present invention is a baby carriage disclosed in Japanese Utility Model Application Publication No. 105559/1983. The push rod of this baby carriage can be switched between two states: a back pushing position and a facing pushing position.

In order to fix the push rod in the rear-pressing position or the face-to-face pressing position, a rotating hook and a locking pin that can be engaged with the rotating hook are provided. The four-turn hook is rotatably provided on a pair of push rods located on the left and right sides, and the locking bins are provided at two locations, one in the front part and one in the rear part of the baby carriage body. In order to rotate the rotary hook, each of the pair of push rods is provided with a knob.

When attempting to release the locked state of the push rod, the rotary hook is rotated by operating a pair of knobs with both hands.

[Problem to be solved by the invention] Japanese Patent Publication No. 58-32065 and Japanese Patent Publication No. 62-13
In the baby carriage disclosed in Japanese Patent No. 230, in order to unlock the open state of the baby carriage, it is necessary to rotate a pair of operating levers upward. When attempting to lock the open state of the baby carriage, it is necessary to rotate the pair of operating levers downward and return them to their original positions.

When converting the baby carriage from a folded state to an open state, the pair of operating levers are brought to an upper position. When the baby carriage is fully opened, the pair of operating levers are rotated downward, thereby locking the baby carriage in the open state. However, due to carelessness, l
I sometimes forget to rotate the paired control lever downward.

In that case, the open state of the baby carriage is not locked.

If the baby carriage is moved in this state, the baby carriage may suddenly start folding when some kind of impact force is applied to the baby carriage, which is dangerous.

In the baby carriage disclosed in Japanese Utility Model Publication No. 60-105559, it is necessary to operate a pair of knobs in order to unlock the push rod.

For example, consider the case where the push rod is switched from a back-pushing state to a facing-pushing state. Before starting the operation, the push rod is locked in the backward push state. To release this lock, rotate a pair of knobs. Next, the push rod is rotated to bring it to the opposing push position. Finally, when the push rod is brought to the face-to-face push position,
Rotate a pair of knobs to fix the position of the push rod.

When performing the above-described operation, it is possible that the user may inadvertently forget to rotate the pair of knobs after bringing the push rod to the opposing push position. In that case, the push bar has been brought into the facing push position, but is not locked. If the baby carriage is moved in this state, the push rod may rotate unexpectedly, which is dangerous.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a baby carriage that can prevent forgetting to perform a lock operation on an operating mechanism.

[Means for Solving the Problems] A baby carriage that is an object of the present invention includes an operation mechanism that performs a desired operation by a predetermined operation, and first and second members that are provided so as to be relatively movable. ing. Operation of the operating mechanism is prohibited when the first and second members are in an engaged relationship with each other, and operation of the operating mechanism is permitted when the first and second members are in a non-engaged relationship.

The present invention is characterized in that such a baby carriage is equipped with a signal generator. The signal generating device includes a switch that is electrically turned on when the first and second members are in an engaged relationship or a non-engaged relationship, and when one relationship is switched from one relationship to the other relationship, When this switch is turned on, it generates a signal that can be recognized by human hearing or vision.

[Operations and Effects of the Invention] It is assumed that the switch is in an off state when the first and second parts are in an engaged relationship. When the first and second members are in an engaged relationship, operation of the operating mechanism is inhibited. In other words, the operating mechanism is in a locked state. When the first and second members are disengaged to cause the operating mechanism to operate, the switch is turned on.

When the first and second members are in a disengaged relationship, operation of the operating mechanism is permitted. In this state, the signal generating device generates a signal that is recognized by human hearing or vision. For example, suppose a signal generating device is generating sound. A person operating the baby carriage recognizes that the contact with the operating mechanism of the baby carriage has been released by hearing the sound generated from the signal generator. Therefore, the person who moves and operates the baby carriage does not forget to lock the operating mechanism. In one mode of use, when the operating mechanism is locked, no sound is heard. In this way, you can be sure that it is locked.

As shown in FIGS. 9 and 10, circular recesses 45 and 46 are formed in the upper surface of the stopper 40. As shown in FIGS. This circular four part 45,46 is the strike. This is to facilitate the sliding operation of the driver's pad 40.

Referring to FIGS. 6 and 7, a stepped portion consisting of a peak portion 28 and a trough portion 29 is formed at the upper end portion of the t-operation button 24 and the portion facing the stopper 40. As shown in FIGS. As shown in FIG. 6, when the stop flange 40 is brought to the left position in the figure, the locking claws 41 and 42 of the stop flange 40 face the peak 28 of the operation button 24. Therefore, the operation button 24 cannot be moved upward from the state shown in FIG.

On the other hand, when unlocking the open state of the baby carriage, first slide the stopper 40 to the right from the state shown in FIG. Then, the locking claws 41 and 42 of the stopper 40 are positioned to face the valley portion 29 of the operation button 24, and a gap is formed between them. Because of this gap, the operation button 24 can be moved upward. In this way, the state in which the operation button 24 is moved upward is the state in which the operation button 24 is moved upward.
The condition is as shown in the figure. As described above, in the state shown in FIG. 7, the pair of disengagement members are pulled by the wires 37, 39 and move upward, thereby pushing the pair of open lock members upward. As a result, the lock in the open state of the baby carriage is released.

With reference to FIGS. 6 and 7, inside the stopper 40,
A sounding device 50 is built-in. FIG. 13A is an illustrative diagram of the sound generating device 50, and FIG. 13B is its electrical circuit diagram.

FIG. 17 is a view of the connecting portion between the push rod 10b located on the right side of the baby carriage and the reversing bracket 6, as seen from the inner surface of the baby carriage. Further, FIG. 18 is a view of a portion related to the reversing bracket 6 located on the right side of the baby carriage, viewed from the rear side of the baby carriage, and FIG. 19 is a sectional view of that portion. Note that in FIGS. 16 and 17, illustration of the seat support rod 9 is omitted for convenience.

Referring to these figures, the inversion bracket 6 is arranged so as to sandwich the rear leg 5 therebetween, and one end thereof is movably connected to the rear leg 5 via a shaft 7. The other end of the reversing bracket 6 is connected via a shaft 12 to the rear end of the seat support rod, the lower end of the handrail support rod 8, and the push rod 10b.
The lower ends of the two are rotatably connected to each other. 1st
As shown in FIG. 8, the push rod 10b is located on the outer side of the handrail support rod 8, the rear leg 5, and the inversion bracket 6, and the seat support rod 9 is located on the inner side of them. There is. When the baby carriage is in the open state, the reversing bracket 6 is fixed at a position along the upper flat part of the rear legs 5, thereby locking the baby carriage in the open state. Further, in the closed state of the baby carriage, the reversing bracket 6 is positioned along the lower half of the rear leg 5.

Referring to FIG. 19, an engagement release member 6 is provided in the push rod 10b.
4 are stored. This engagement release member 64 is connected to the push rod 1
It can move up and down within 0b. Wire 3 shown in FIG.
The two lower ends are connected to an engagement release member 64 . As described above, the disengagement member 64 is constantly urged to move downward by a spring (not shown).

When the operating button 24 shown in FIG. 4 is manually operated and moved upward, that is, when the state shown in FIG. 5 is achieved, the disengagement member 64 is pulled up by the three wires and moved upward. This state is the state shown in FIG.

The engagement release member 64 has a push-up portion 64a that projects toward the inner side of the baby carriage. This push-up portion 64a
protrudes beyond the wall of the push rod 10b. Correspondingly, as shown in FIG. 17, a long hole 66 for guiding the push-up portion 64a is formed in the push rod 10b.

As shown in FIG. 19, a vertically elongated guide hole 69 is also formed in the lower end portion of the handrail support rod 8. An open state locking member 67 is housed in the guide hole 69 so as to be movable up and down. As shown, open locking member '67
has an engagement shaft portion 67a protruding toward the outer side and the inner side. Further, as shown in FIG. 19, a spring 68 is housed between the open state locking member 67 and the handrail support rod 8, so that the open state locking member 67 is always urged downward. .

With reference to FIGS. 16 and 17, the inversion bracket 6
An engagement recess 6a is formed in which the engagement shaft 67a of the open state locking member 67 is received. In the open state of the baby carriage, the engagement shaft portion 67a of the open state locking member 67 and the engagement recess 6a of the reversing bracket 6 are in an engaged state, thereby inhibiting rotation of the reversing bracket 6 and locking the baby carriage. The open state is locked.

17, 18, and 19, when the engagement shaft portion 67a of the open state locking member 67 and the engagement recess 6a of the reversing bracket 6 are in the engaged state, the engagement shaft portion 67a is in the engaged state.
7a is located in contact with the push-up portion 64a of the engagement release member 64. The open state locking member 67 is movable between an upper position and a lower position. Similarly, the disengagement member 64 is also movable between an upper position and a lower position.

In the state shown in FIG. 19, the open state locking member 67 is in the lower position, and the engagement release member 64 is also in the lower position.

FIG. 20 is a drawing corresponding to FIG. 19. In the state shown in FIG. 20, the open lock member 67 is in the upper position and the disengagement member 64 is also in the upper position.

16 to 20 show the structure of the portion located on the right side of the baby carriage. However, it must be understood that the structures of the parts located on the left and right sides of the baby carriage are basically the same.

Next, the overall operation will be explained.

As shown in FIG. 1, it is assumed that the open state of the baby carriage is locked. In that case, the operation button 24 and the stopper 40 arranged in the center of the pushpiece connecting member 11 are
in the position shown in the figure. In order to remove the lock from the open state of the baby carriage, the stopper 40 must first be slid.

Therefore, the operation button 24 will not move upward against the user's will, and therefore, the lock on the open position of the baby carriage will not be released unexpectedly.

Further, in the embodiment shown in FIG. 6, the operation button 24 protrudes downward from the bottom surface of the push rod connecting member 11, and the stopper 40 is arranged on the upper surface of the push rod connecting member 11. If the switch 1, the collar 40, and the operation button 24 are arranged in such a positional relationship, it becomes very easy to photograph. That is, when grasping the push rod connecting member 1 with fingers, the thumb is usually positioned on the bottom side of the push rod connecting member 11, and the remaining four fingers are positioned on the upper side of the push rod connecting member 11. Or, conversely, the thumb is positioned on the top side of the push rod connecting member 11, and the remaining four fingers are positioned on the bottom side of the push rod connecting member 11. Therefore, for example, you can operate the stopper 40 with your thumb and the operation button 2 with your remaining four fingers.
4 can be operated.

When the stopper 40 is in the left position as shown in FIG. 6, the movable terminal 51 of the sound generating device 50 is separated from the fixed terminal 55 as shown in FIG. Therefore, no sound is emitted from the sound generating device 50. In other words, when the stopper 40 prohibits upward movement of the actuation button 24, no sound is emitted from the sound generating device 50.

Next, it is assumed that the stopper 40 is manually operated and moved to the right position as shown in FIG. In this case, as shown in FIG.
5. As a result, sound is emitted from the sound device ffi50. When the sound generation device 50 is producing sound, the operation button 24 can be moved upward. When the operating button 24 is moved upward as shown in FIG. 7, the pair of rotating members 22, 23 shown in FIGS. 4 and 5 rotate in opposite directions, and the wires 37, 3
9 is pulled upward along a pair of quick sticks 10a and 10b. The disengagement member 64 shown in FIG. 19 is then pulled upwardly by the wires 37, 39.

Referring to FIG. 20, when the disengagement member 64 moves upward, the open state locking member 67 is pushed up by the push-up portion 64a and reaches the upper position.

As a result, the engagement between the engagement shaft portion 67a of the open state locking member 67 and the engagement recess 6b of the reversing bracket 6 is released. Therefore, the reversing bracket 6 is allowed to roll. In other words, the open state of the baby carriage is unlocked, and the baby carriage can be folded.

Until the stroller changes from the open state to the folded state,
Sound is being emitted from a sounding device. Although not shown, when the baby carriage reaches the folded state, if you release your hand holding the operation button 24 and move the operation button 24 to the lower position, the open state locking member 67 will be moved to the predetermined position of the reversing bracket 6. to lock the folded state of the stroller by engaging the position.

Even in this state, the stopper 40 is
As shown in FIG. 5, when it is in the right position, the sound generating device is emitting sound. Therefore, the person who is drying the baby carriage can recognize that the stopper 40 is not in the locked position by hearing the sound.

Finally, after the folded state of the baby carriage is locked, if the stopper 40 is manually moved to the left position as shown in FIGS. 6 and 14, no sound will be emitted from the sounding device 50. . When the stopper 40 is in the position shown in FIGS. 6 and 14, upward movement of the operating button 24 is prohibited. Therefore, even if the person operating the baby carriage unconsciously grasps the operation button 24 with his/her hand, the operation button 24
does not move upwards, and the folded position of the stroller is never unlocked.

The embodiment described above is only one example embodying the present invention. Therefore, within the scope of equivalents of this invention,
Occasional modifications and transformations are possible.

Some of the modifications will be explained below.

21 to 24 show other embodiments of the invention. In these figures, elements labeled with the same numbers as in the previous embodiments indicate the same or equivalent elements as in the previous embodiments.

As shown in FIG. 21, when the slide lock member 70 is in the lower position and engaged with the engaging portion 6a of the reversing bracket, the open state of the baby carriage is locked.

When the slide lock member 70 is pulled upward by the wire 83 from the state shown in FIG. 21, the engagement state between the slide lock member 70 and the engagement recess 6a of the reversing bracket 6 is released, and the stroller is in the open state. The lock will be released.

In the state shown in FIG. 22, the inversion bracket 6 is placed along the lower half of the rear leg 5, and the slide lock member 70 is engaged with the engagement recess 6b of the inversion bracket 6. In this state, the folded state of the baby carriage is locked. From the state shown in FIG. 22, the slide lock member 7
0 is pulled upward by the wire 83, the engagement between the slide lock member 70 and the engagement recess 6b of the reversing bracket 6 is released, and the lock on the folded state of the baby carriage is released.

Although not shown, the slide lock part +K70 has a built-in sound generating device. FIG. 23 schematically shows the bottom surface of the slide lock member 70. As shown in the figure, two electrode terminals 71 and 72 of the sound generating device are exposed on the bottom surface of the slide lock portion 70. 2
The electrode terminals 71 and 72 are provided at separate locations. If the two electrode terminals 71 and 72 are electrically connected,
A sound is emitted from a sounding device. The pronunciation device is constant■! j
It is equipped with a timer to make the sound only for a certain period of time. Therefore, after the two electrode terminals 71 and 72 are electrically connected, sound is emitted for a certain period of time, and no sound is emitted after the elapse of a certain period of time.

FIG. 24 schematically shows the surface of the engagement recess 6a of the reversing bracket 6. A conductive plate 81 is attached to the surface of the engagement recess 6a. Similarly, a conductive plate 82 is also attached to the surface of the other engaging recess 6b of the reversing bracket 6.

The operation when moving the baby carriage from an open state to a folded state will be explained. First, the slide lock member 70 is moved upward from the state shown in FIG. If you start the folding operation of the stroller in this state, the reversing bracket 6
rotates in the direction of the leaf meter in the figure, and reaches the position shown in FIG. 22. Further, when the slide lock member 70 is moved downward, the slide lock member 70 and the engagement gate 6b of the reversing bracket 6 are engaged, and the folded state of the baby carriage is locked. At this time, if the slide lock member 70 and the engagement recess 6b of the reversing bracket 6 are completely engaged, the two electrode terminals 71 and 72 provided on the bottom surface of the slide lock member 70 will be engaged. Electrical connection is made via a conduction plate 82 attached to the mating recess 6b. Therefore, the sound generating device built into the slide lock member 70 emits sound for a certain period of time. By hearing this sound, the person operating the baby carriage can recognize that the folded state of the baby carriage is completely locked. On the other hand, when no sound is emitted from the sound generating device, the slide lock member 70 and the engagement recess 6b of the reversing bracket 6 are not completely engaged. In other words, the stroller is not fully locked in its folded state. Therefore, by knowing that no sound is emitted from the sound-producing device, the operator can recognize that the stroller is not fully locked in the folded state.

The above-mentioned operation also applies to the transition of the nanny book from the folded state to the open state. That is, when the baby carriage is opened and the slide lock member 70 is moved downward, if a sound is emitted from the sound device, the slide lock member 70 and the engagement recess 6a of the reversing bracket 6 are completely engaged. I feel lazy about the fact that I am in a state of harmony. That is, it means that the stroller is completely locked in the open state. On the other hand, if no sound is emitted from the sound-producing device,
This means that the engagement state between the slide lock member 70 and the engagement recess 6a of the reversing plaque/slot 6 is incomplete, and the locking of the baby carriage in the open state is incomplete.

In the embodiments described above, the main parts of the present invention have been explained with respect to the locking mechanism for the open or folded state of the baby carriage.
This invention can also be applied to ^1. for example,
In the baby carriage shown in FIG. 1, a rotating hook 15 was used as a locking member for the push bar, but instead of this rotating hook, it may be possible to slide up and down along the push bars 10a and 10b. Suppose a slide hook is provided. Then, the lower end of the wire 37, 39 shown in FIG. 4 is connected to the slide hook. In this way, by operating the operation button 24, the push rods 10a, 10b can be locked.

Needless to say, even in such an embodiment, the sixth
A stopper 40 having a built-in sounding device as shown in the figure is employed.

Furthermore, in the baby carriage shown in FIG.
5 and the locking pin 16, 17 are securely engaged, electrode terminals 71, 72 and a conductive plate 81 as shown in FIGS. may be provided. In this case, when the rotating hook and the locking pin are securely engaged, a sound is emitted for a certain period of time.

As a modification, a light emitting device that generates light may be used instead of a sound generating device that generates sound.

In short, the present invention provides electrical power when the first and second members, which are provided so as to be relatively movable, are switched from one of the engaged relationship and the non-engaged relationship to the other relationship. The present invention is characterized in that it has a switch that is turned on when the switch is turned on, and a signal generator that emits a signal that is recognized by human hearing or vision in response to the switch being turned on.
