  However, going out in the seat for a long time is often an unpleasant event for infants. Usually, going out is done at the parent's will. That is, the parent sets the time and place to go out for reasons of housework, etc., and takes the child out for shopping or meals. Children up to about 2 years old are not yet able to communicate well with their parents and are unable to properly communicate with their parents. It also leads to problems such as the child's feelings and bad mood and crying. When going out, you need to stop crying as soon as possible in consideration of the inconvenience of others, which leads to great stress for parents.

  According to the prior art, the comfort of the seat itself is improved by improving the seat itself, but it is possible to move around freely in a quiet house by being fixed to the seat for hours. From the situation, it seems that the situation is still uncomfortable.

  Thus, the conventional approach to improving a stroller has been examined in the direction of removing unpleasant elements in the stroller, and such an approach is passive. In other words, the final destination point in the above problem improvement posture is to manufacture a stroller that is not uncomfortable, and it was aimed at a point where we would go one step further and make the stroller a vehicle that children would want to ride actively. It was not an approach.

By sliding and extending each pipe, the cap portion can be further pulled out in the direction of the arrow as shown in FIG. By adopting a configuration in which the cap portion can be pulled out in this way, a certain distance from the infant to the image display device can be ensured, so that the screen is easier to see.

The stroller according to the present invention has been described above. As described above, in the stroller according to the present invention, by installing video playback means for playing back video and music playback means for playing back music on the stroller, infants can enjoy their contents while riding in the stroller. Can do. Conventionally, a baby stroller is a boring vehicle that only allows a baby stroller to be seated, whereas the baby stroller of the present invention is a fun vehicle that provides stimulation.

In particular, since it is difficult for infants to attach headphones and earphones well, music can be enjoyed by arranging speakers around the seat. Here, the location of the speaker can be changed as appropriate in consideration of the wiring efficiency in the seat portion, the back pipe, the armrest, and the like.

For parents and guardians, because they are obsessed with video and music content, they can sit quietly in the stroller, reducing the frequency of sudden crying or boring and rampage. , Can reduce stress when parents go out.

At present, since it is generally accepted that light weight of baby strollers is a consumer's needs, it is not a consideration to newly increase the weight of conventional baby strollers. In particular, the installation of a plurality of members such as batteries, image display devices, operation devices, etc. will increase the weight from several hundred grams to several kilograms. The stroller manufacturing process that seeks to gain an advantage is a significant reversal. However, when the actual use state of the stroller is closely observed, it is understood that most of the use state is moved while the stroller is rolled, and the rate of movement while the stroller is lifted is very small.

In recent years, it has been designed so that a stroller can be passed as it is at a ticket gate of a station or a supermarket cash register, and there is an environment in which the stroller can be moved as it is, for example, enhancement of elevators and good paving of roads. Thus, in the present situation where most of its use can be pushed and moved, the weight increase of the stroller body up to several kilograms is not as disadvantageous as is generally thought, and the child is a little quieter than that The merit of being able to do is actually much larger. The baby stroller of the present invention can have a great effect while partially sacrificing the increase in weight.

Moreover, the period from 0 years old to about 2 years old is an important time for the infant to form a brain, and it is desirable to give various stimuli from outside to learn various things. For example, since it is necessary to remember the formation of absolute pitch in early childhood, it is important to let the music come into contact at an early stage, and learning material content for infants can be played on the image display device. . Also, it is possible to use a method in which a moving image showing the appearance of the mother is stored in a recording medium in advance and the anxiety of the infant is removed by flowing this moving image.

It is also effective to arrange several simple input buttons on the surface of the image display device so that simple training and games can be performed.

Here, the liquid crystal display (LCD), the electronic paper (Electric Paper), the organic EL (OELD), the field emission display (FED), the plasma display (PDP) are used for the image display device and the image display unit from the viewpoint of weight reduction and space saving. ), Etc. It is better to use a thin panel. Moreover, as the size of the panel, a size of about 4 to 12 is an appropriate size as a range that fits in the cap portion. However, the type and size of the panel are not limited to these. Moreover, since it is assumed that it is mainly used outdoors, the panel excellent in flexibility is more preferable so that it can respond to the impact from the outside.

Further, the image display device, the operation device, and the like may be subjected to a treatment for suppressing the emission of electromagnetic waves to the surroundings using an electromagnetic wave prevention film.

In the above description, the image display device and the speaker are arranged in different places. However, the present invention is not limited to this, and a content playback device in which the video display device and the speaker are integrated may be attached to the back side of the cap portion. good. With this configuration, since the signal lines of the video signal and the audio signal can be wired with a pair of cables, the complexity and cost of wiring can be reduced.

In the above description, an example is shown in which content is read from a card-type recording medium such as a flash memory. However, the present invention is not limited to this, and a configuration may be adopted in which content is read from a medium such as a DVD, CD, or HD. Here, since the DVD drive and the HD drive are larger than the card-type reading slot, these reading devices may be arranged in places such as the back side, the side surface, and the bottom surface of the seat portion, like the battery. . In this case, a processing unit that performs video / audio processing may be provided integrally with the reading drive.

Moreover, although the example which reads a content from a recording medium was shown in the said description, it is not limited to this, For example, the structure using the contents by radio | wireless broadcasting, such as a 1 seg, may be used. In this case, a reception antenna that receives a radio signal, a radio reception unit that performs reception processing such as down-conversion and A / D conversion on the signal received by the reception antenna, FFT processing, equalization processing on the received signal, A separate wireless receiving device is required which includes decoding processing means for performing error correction decoding processing and the like, and content processing means for performing motion compensation processing and codec processing on the decoded video and audio signals, respectively. Power is supplied from the battery to the wireless reception device, control signals such as channel selection and volume adjustment are input from the operation device, and a video signal and an audio signal are transmitted to the image display device and the speaker, respectively. In addition, as a configuration in which a stroller can be connected to a terminal such as a mobile phone having a one-segment reception function, a configuration in which the one-segment broadcast received by the mobile phone can be displayed on the image display device may be employed.

Further, for charging the battery, a power cord with a power plug may be provided instead of the power jack. With this configuration, the battery can be charged simply by connecting the power plug to the outlet, and convenience is improved.

As the battery, it is advantageous from the viewpoint of weight reduction to use a secondary battery having a high energy density such as a lithium ion battery.

In addition, the battery may be detachable, and the battery may be removed and charged when charging. Such a configuration eliminates the need for a power supply power jack, thereby reducing the weight. In addition, when the stroller is no longer used, the battery can be reused for other products, which is economically advantageous.

The attachment of the image display device to the cap is not limited to the method shown in FIG. For example, as shown in FIG. 9, the connecting member 55 is attached to the adjacent cap frame 51, and the connecting members are connected by the mounting frame 56, and the image display device 50 is fixed to the mounting frame. It may be. At this time, if the image display device is configured to be slidable up and down along the mounting frame, the image display device can be easily arranged at the eye level of the infant. In addition, the image display device 50 may be directly locked to the cap portion with an adhesive or a bolt.

Further, a vent hole may be provided in the cap portion where the image display device is installed so that heat can be exhausted to the outside.

Further, a mounting member for mounting the image display device such as a mounting pocket or a mounting frame is provided inside the cap portion, and the image display device itself may be detachable. The average birth rate in the world in recent years is about 2,69, and when a stroller is used from 0 to 2 years old, it is calculated to be used for about 5 to 6 years in total. Even if it is used for 3 hours a day, it will be used for about 5000 to 7000 hours. Actually, since the birth rate has recently decreased and the time for viewing the image display device while riding a stroller is only a part, the actual use time of the image display device is assumed to be about 1000 hours. Although the image display panel in recent years has durability of tens of thousands of hours, the life of the image display panel and the usable time usually do not coincide with each other because the use time of the stroller is limited. Therefore, the stroller body is provided with a support portion that supports the four corners of the image display device or a support frame that supports the four sides, and the image display device itself is detachable and recycled. It is advantageous from the viewpoint of economic efficiency.

In addition, it is more economical to use an inexpensive image display panel having a durability time of about several thousand hours as the image display device. Since image display devices that display normal images have a lifespan for replacement of image display devices, it is important for TVs to have a long life for image display panels used for computer displays. Since the life of the display device is the end of use of the stroller, the image display device itself is not required to have a long life. Therefore, demand can be created even for a panel that does not satisfy the requirements for use in a television or the like from the viewpoint of short life, such as organic EL.

In addition, the cap part is made of a transparent sheet or mesh such as vinyl, so that even when the cap part is unfolded, an infant who is watching videos and music from parents can be seen. It can be confirmed, and the parent can be seen by looking back from the infant, so anxiety can be reduced.

Further, since the deployment and storage of the cap part is performed not only in the case of sunshade and rain protection but also in the presence or absence of viewing of video content, the frequency of opening and closing the cap part increases, so that the cap part and A cap opening / closing handle may be separately provided at the pivoted portion of the back pipe so that the opening / closing operation can be easily performed. The base of the cap opening / closing handle is provided with a plurality of teeth. By rotating the cap opening / closing handle around the rotation axis, the rotation is transmitted to the cap via a gear to open / close the cap. A small electric motor for opening and closing is installed at the base of the cap, and a cap opening / closing button is provided on the operating device 70. When the cap opening / closing button is pressed, the small transmission motor is rotated to open and close the cap. You may comprise. By doing in this way, the opening and closing work of the cap part which increases by arrange | positioning an image display apparatus can be performed with little effort.

Moreover, the cap part 14 does not need to be pivotally attached to the back pipe 12, and may be pivotally attached to the seat part 8 or the handle 15, for example, or may be arranged in a state of being hooked on the seat part or the back pipe. Good.

Further, as shown in FIG. 11, the image display device 50 may be separately attached to the mounting arm 92 instead of inside the cap portion 14. The arm 92 is pivotably attached to the side surface of the back pipe 12 or the seat portion 8 in a rotatable state, and has a configuration that can be expanded and contracted in a multistage manner. When in use, the arm is rotated to place the image display device at the eye level, and the arm is extended to ensure the distance from the image display device to the eye. When not in use, retract the arm and rotate it upwards. As described above, newly installing the display means for the image display device causes an increase in weight and cost, but on the other hand, since the image display device can be seen without unfolding the cap, You can enjoy it at the same time.

Further, as another form of arrangement of the image display device 50, the image display device 50 can be stored on the side surface of the seat portion 8 or the side surface of the armrest 9 when not in use, and the image display device is pulled out to the front of the seat portion 8 when in use. May be used. In this case, it is preferable that the arm to which the image display device is attached is configured to be freely stretchable and provided with angle adjusting means that can change the angle of the image display device.

In the above description, an example in which both the image display device and the speaker are provided has been described, but a configuration in which only one of them is provided may be employed. By using only a speaker as the content playback means, it is possible to reduce the weight and save battery while making music enjoyable for infants.

In addition, the stroller body can be applied to a stroller having a folding mechanism or a reclining mechanism in a seat portion.

In addition, the front wheel and the rear wheel can be attached and detached, and by separately attaching fixing feet, even after the period of use as a stroller is over, it can be reused as a chair for viewing content in the room.

In addition, since the battery is mounted on the stroller, a small fan or the like can be arranged near the seat or in the cap using this power supply source. Since infants' body temperature is high, a more comfortable baby stroller can be provided by installing an air conditioner.

In addition, the present invention applies the present invention to all wheelbarrows having seats for infants and children, such as A-type, B-type, and AB-shared strollers defined by SG standards, and buggy cars. Is possible.

In addition, the design of the present invention can be changed as appropriate without departing from the scope of the invention.

In this way, the stroller has a means to play content such as videos and music, providing a space where infants can relax and enjoy, and adults who are parents can control, play, stop, etc. the content. By providing operation means for performing the operation in places where the stroller is pushed, such as the handle portion or the back of the stroller, the guardian can control well according to the infant's condition.

  The stroller according to the present invention can be widely used as a stroller with improved added value.
