Next, an embodiment of how the cradle with an image display device according to the present invention is actually realized will be described. FIG. 1 is a perspective view showing the entire contents of an embodiment of a cradle with an image display device according to the present invention. Both ends of the cradle 1 in the height direction are attached to and supported by a support stand 2 in a reciprocating manner.
The cradle 1 has a structure in which a bottom frame 4 on which a bottom plate 3 is attached and supported in a replaceable manner is suspended from an upper frame 5 by a net N.
In the cradle 1, the left-right direction is the height direction of the infant in the state of sleeping so that the infant can sleep in the left-right direction. Accordingly, the bottom plate 3, the bottom frame 4, and the upper frame 5 are longer than the height of the infant sleeping inside, for example, a length of about 80 to 120 cm is suitable. The width direction is suitably about 40 to 50 cm, for example, for a single person, and about 50 to 80 cm, for example, for a plurality of persons.

The bottom plate 3, the bottom frame 4, and the upper frame 5 are substantially rectangular, and both ends in the height direction are formed in an arc shape, and mounting support arms A 1 and A 2 are attached to both ends in the height direction of the upper frame 5. Installed and fixed vertically. If the support arms A1 and A2 are unstable only by the upper frame 5, if the support arms A1 and A2 are extended to the bottom frame 4 and fixed to the bottom frame 4, the entire cradle 1 integrally and stably swings so that the motor can be driven smoothly. It becomes.
FIG. 2 is a partial sectional side view showing a connecting portion between the support arms A1 and A2 and the drive motor. The horizontal shaft 6 is reciprocally rotated by the reciprocating shaft of the motor unit U.
The horizontal shaft 6 and the upper ends of the pair of support arms A1 and A2 are connected and fixed and reciprocally rotate together. In this case, it may be directly connected and fixed, but in the illustrated case, it is connected and fixed via the bracket 7.

On the other hand, the support stand 2 arranges a pair of foundation pipes 8 and 9 in parallel with each other and connects and strengthens the middle with a connection pipe 10 so that both ends of the foundation pipes 8 and 9 stand up and support columns 81. 82, 91 and 92 are formed.
A detachable structure is provided between the base pipe 8 and the connecting pipe 10 and between the columns 81 and 82. Further, since the base pipe 9 and the connecting pipe 10 and between the columns 91 and 92 are detachable, disassembly and assembly are easy.
In the left side of the figure, the columns 81 and 82 on the left are gradually spaced closer to the upper end, and the upper end is connected and fixed to the bearing bracket 11. In the same manner, the right support columns 91 and 92 are also gradually spaced from each other toward the upper end, and the upper end is connected and fixed to the bearing bracket 12.
As shown in FIG. 2, the horizontal shaft 6 is inserted into a horizontal through hole opened in the right bearing bracket 12, and one end of the horizontal shaft 6 can be interlocked with the reciprocating shaft of the motor unit U. It is fixedly connected to the connecting bracket 7 of the cradle. Therefore, when the reciprocating shaft of the motor unit U is reciprocated, the pair of support arms A1 and A2 and the cradle 1 are reciprocally swung together via the connecting bracket 7 connected and fixed to the horizontal shaft 6 to reciprocate as a cradle. Swing.

FIG. 3 shows the internal structure of the motor unit U. A link L is pivotally connected to an eccentric position of a worm gear G that meshes with a worm W connected and fixed to the output shaft of the motor M. The other end of the link L is connected to a position below the horizontal shaft 6 of the connecting bracket 7 with a support shaft.
Therefore, when the output shaft of the motor M and the worm W are continuously rotated and the worm gear G is rotated at a reduced speed, the rotational movement of the left end of the link L is a reciprocating swing in the direction of the arrow a1 on the right side, and The support arms A1 and A2 and the cradle 1 are reciprocally swung. In this case, the connection bracket 7 (the horizontal shaft 6 is inserted and supported as shown in FIGS. 1 and 2) and the horizontal shaft 6 do not necessarily need to be connected and fixed, and the horizontal support shaft 6 is the center. It is sufficient if the connecting bracket 7 can swing back and forth.

Thus, in FIG. 3, the reciprocating rocking force is transmitted to the connecting bracket 7 by the link L. However, the reciprocating rocking body (7) is also built in the motor unit U, and the horizontal shaft 6 is reciprocated to rotate. A structure in which the connecting bracket 7 of FIGS. 1 and 2 is reciprocally swung by the reciprocating rotational force of the horizontal shaft 6 is also possible.
In this case, as shown in FIG. 2, the connecting bracket 7 and the horizontal shaft 6 are fixed, and the horizontal shaft 6 reciprocates with respect to the bearing bracket 12 of the support stand 2.
In addition, it is also possible to connect the link L to the bottom frame 4 and the upper frame 5 of the cradle 5 and the support arms A1 and A2 so that the cradle 1 side is reciprocally swung by the link L of the motor unit U.

As shown in FIG. 1, one end of a serpentine tube 13 is attached and fixed to a connecting bracket 7 on the left side of the figure, and a thin image display panel 14 such as a liquid crystal type or a plasma type is attached to the other end as an image display means. . Accordingly, when the cradle 1 swings back and forth, the image display panel 14 also swings back and forth at the same time, so that the infant in the cradle 1 sees the image display panel 14 while sleeping and receives early infant education. Can do.
Since the image display panel 14 is attached via the snake tube 13, the angle and position of the image display panel 14 can be freely changed according to preference. The serpentine tube 13 is not limited to the connecting bracket 7 and can be attached to the support arms A1 and A2 and the upper frame 5 side of the cradle.
Further, when the flexible tube 13 and the connection bracket 7 and / or the image display panel 14 are connected by a universal joint, the orientation and position of the image display panel 14 can be easily adjusted. The image display device 14 preferably has a thin panel structure such as a liquid crystal type or a plasma type. It can be easily reduced in weight and can be safely installed in the upper position of an infant.

In the above configuration, the pair of support arms A1 and A2 are connected to the upper connection bracket 7 with a space therebetween, so that a robust structure is obtained. Is possible.
To prevent the cradle 1 from inadvertently moving due to malfunction or operation, it is safe to connect the bottom frame 4 and the pair of foundation pipes 8 and 9 or the columns 82 and 92 with the connecting means 15 when not in use. is there. Even if an infant is blown inside, the stability of the cradle 1 can be secured, and it is safe and secure.

Instead of the net N between the bottom frame 4 and the top frame 5, a cloth or a synthetic resin sheet may be used instead. When cloth is used, a net shape such as organdy may be used. In FIG. 1, the x mark is a connecting part by welding or the like.
As shown in FIG. 4, if the corners between the pair of foundation pipes 8 and 9 and the upright columns 81 and 82 and 91 and 92 are inserted into the corner cover 16 for protection, the bottom surface of the corner cover 16 is obtained. Therefore, the stability of the entire cradle 1 is increased, and even if it is placed on a tatami mat, it can be prevented from being dented and damaged.

Further, when the sprinkle S is interposed in the link L shown in FIG. 3, if the movement of the worm gear G is transmitted to the connecting bracket 7 via the buffer means by the sprink S, the cradle does not make a shocking movement. With a slight delay, it will always be slow and soft. Further, when the motor is started, the reciprocating swing stroke of the cradle is small, and gradually becomes a large stroke due to inertia.
In order to prevent the interval between the left and right connecting brackets 7 to 7 in FIG. 1 from approaching with the weight of the cradle 1, a support bar can be inserted between the connecting brackets 7 to 7. A structure in which the cradle 1 is reciprocally swung is also possible.

If you do not want to provide a support bar on the baby in the cradle 1, extend the extension bar from the base pipes 8 and 9 to the left and right, and connect the wires between the tips and the connecting brackets 7 and 7. It is also possible to prevent the distance between the connecting brackets 7 to 7 from being approached by the weight of the cradle 1.
By interposing a horizontal axis in a direction orthogonal to the support horizontal axis 6 between the connecting brackets 7 and 7 and the pair of support arms A1 and A2, the pair of left and right support arms A1 and A2 By allowing the cradle 1 to rotate only in the direction perpendicular to the swinging direction of the cradle 1 (the height direction of the infant inside) around the axis, it is possible to absorb problems caused by changes in the distance between the connecting brackets 7 to 7.

As described above, since the cradle 1 is equipped with the image display panel 14, when the infant starts crying, the sound is detected and the infant's favorite music or image is automatically started. This is safe and reduces the burden on the mother.
If it is detected that the child has stopped crying, software for early childhood education of the infant can be started.
Naturally, the contents displayed on the image display panel 14 can be used in conjunction with audio explanations as in the case of a television, etc., and display explanations of various stories and software such as various infant education programs can be used. .

As described above, according to the present invention, since the thin image display panel is also reciprocally swung together with the reciprocal swing of the cradle, the infant inside the cradle can see the image display device at an early stage. Can receive education.
Equipped with panel-type video equipment in this way, it is suitable for infants' emotional education, such as mothers and family voices and images, voices and images of infants of the same age playing in nurseries, beautiful natural conditions, etc. Since it can be used at any time in the cradle, it is effective in preventing child-rearing phobias and child-rearing neuroses, and can contribute to solving problems in the declining birthrate society.
