Description

Electric Baby Cradle {BABY CRADLE WITH ELECTROMOTION}

The present invention relates to an electric baby cradle, and more particularly, to an electric baby cradle in which the baby cradle is repeatedly moved up and down without shaking.

Generally, when an infant is upset or anxious to sleep, their parent or guardian shakes the infant, so that the infant can maintain a comfortable and stable state or take a good sleep. In the past, most of the infants were shaken by holding or carrying them, but recently, the convenience of parents of infants has been improved because the infants can be stably rocked to rest or sleep using a rocking bed.

In particular, a cradle is used to put a baby to sleep, and most cradles have a cradle that is a space for a baby to lie down, a support provided on the periphery of the cradle, and one end is fixed to the upper end of the support and The other end is composed of four strings connected to the upper periphery of the cradle.

In the cradle configured as described above, a person directly shakes the cradle in both directions in a state in which the baby is laid on the cradle to induce sleep of the baby.

However, since most babies do not sleep right away while lying on the cradle, and the cradle has to be shaken continuously until the baby falls asleep, the arm of the person who shakes the cradle will be overworked, which causes fatigue first. cases occur frequently.

In order to prevent this, various electric cradles in which the cradle body is shaken by an electric motor have been devised.

In the prior art that performs the above functions, as shown in Republic of Korea Utility Model Registration No. 0281692, the support between the supports is transversely inserted between the support columns on both sides with wheels, so that the support between the support and the support shaft is erected and the support angle is installed. In the known cradle bed in which the support angle of the cradle bed is installed on the pedestal, an electromagnet fixing plate is installed to be fixedly inserted into the connecting rod connecting the left and right side supports, and two electromagnets facing each other at a certain distance are fixed thereon. Between the electromagnet poles facing the two electromagnets, a permanent magnet is installed at the bottom of the supporter attached to protrude from the bottom of the support angle support, so that the permanent magnet can receive the magnetic force between the two electromagnet poles, and a power circuit for the operation of the electromagnet is constructed. It consists of a fully equipped electric cradle bed.

However, the prior art configuration has the following problems.

There is a problem that it cannot give comfort to the baby because it does not move up and down.

As shown in Korean Patent Registration No. 1496732, in the prior art for moving the bed up and down, as shown in Korean Patent Registration No. 1496732, a pair of guide tubes having guide grooves are formed to correspond to each other on both sides of the longitudinal inner peripheral surface, and hinge pieces are formed to correspond to the rear both sides of the inner peripheral surface. The upper frame is formed in a pair, and a plurality of moving wheels are formed on the bottom edge portion; The upper and lower portions form a corresponding pair connected by the first upper and lower connecting bars, while the upper end of the first link bar is coupled to the hinge piece, and the upper and lower portions are connected by the second upper and lower connecting bars. Link-type support consisting of a pair of second link bars, the middle portion is hinged in the form of "X" with the first link bar and the upper end is coupled to the guide tube; The actuator is hinge-coupled to the first lower connecting bar of the first link bar, and the protruding rod is hinged to the second upper connecting bar of the second link bar to control the unfolding and folding of the first and second link bars.

ater; and a controller for manipulating the rising and falling rod of the actuator; in the movable patient bed configured to include a height-adjustable, the first link bar, the upper end of which is rotatably hinged to the hinge piece, and the lower end supports the wheel A side is formed and a wheel is shaft-coupled, and a roller is shaft-coupled to the upper outer surface of the second link bar, and the shaft enters into the guide groove of the guide tube and the roller is accommodated in the guide tube to be slidable. , The lower end is configured to be hinged with a support piece having a support foot for anti-slip and formed on the support piece of the fixture.

In addition, in order to move the patient easily, the bed is raised and lowered by operating the X-Link as a cylinder, but it is difficult to repeatedly elevate and lower, and there is a problem in that it is difficult to control the shaking of the bed due to the movement of the X-Link during elevating and lowering.

In particular, the power of the motor 310 is transmitted to the driven member 317 installed on the rotating shaft 320 through the sprocket-shaped main member 313 and the belt 315. In addition, bearings 321 are installed on both sides of the rotation shaft 320 and are seated on the body part 500 . Here, the crank 330 is installed on both sides of the rotation shaft 320 to rotate. Furthermore, the rod 331 is rotatably installed on the crank 330 .

A first shaft 333 coupled to the first support groove 111 formed on the bottom surface of the bed unit 100 is installed at the end of the rod 331 . In this case, the first axis 333 is arranged to be spaced apart from each other in a horizontal manner.

After all, the electric baby cradle 10 according to an embodiment of the present invention is installed while supporting both sides of the lower part of the bed 100 so as to repeatedly move the baby cradle up and down, and receives the power of the motor 310 to operate the bed 100 in a crank 330 manner. Through the operation unit 300 that moves up and down, it is possible to take emotionally stable sleep by repeatedly moving the bed up and down without a separate control device.

On the other hand, the support link 400 is installed to support a plurality of places in the lower part of the bed unit 100 perpendicular to the support direction of the operation unit 300, and is folded and expanded in conjunction with the operation unit 300. In this case, the support link 400 is installed such that the bar-shaped first link 410 and the second link 420 are rotated through the rotation pin 320 .

In addition, a second shaft 411 coupled to the first support groove 111 formed on the bottom surface of the bed unit 100 is installed at the end of the first link 410 . Furthermore, a third shaft 421 coupled to the second support groove 511 formed on the upper portion of the body 500 is installed at the end of the second link 420 . In addition, a connecting bar 430 is installed between the pair of first links 410 and second links 420 .

After all, the electric baby cradle of the present invention is installed so that the baby cradle 10 is moved without shaking, a plurality of places under the bed unit 100 are vertically supported in the support direction of the operation unit 300, and folded and expanded in conjunction with the operation unit 300 Through the support link 400, it provides comfort.

In particular, the second axis 411 and the third axis 421 are vertically horizontal and installed in a vertical direction to the first axis 333 . In addition, the second shaft 411 and the third shaft 421 support each of four places of the bed part 100 and the body part 500 .

Here, the first shaft 333 to the third shaft 421 are coupled to the bed part 100 or the body part 500 through the fastening member 800 passing through the first shaft 333 to the third shaft 421 as shown in FIG. 5 .

That is, the first axis 333 limits the degree of freedom in the width direction of the bed unit 100, and the second axis 411 limits the degree of freedom in the longitudinal direction of the bed unit 100.

As a result, the electric baby cradle 10 of the present invention is installed such that the first link 410 and the second link 420 are pivotally installed so that even if the load is concentrated on the baby cradle, the first link 410 and the second link 420 are installed at the end of the first link 410 on the bottom surface of the bed unit 100. A second shaft 411 coupled to the support groove 111 is installed, and a third shaft 421 coupled to the second support groove 511 formed on the upper portion of the body 500 is installed at the end of the second link 420, and the pair of The connection bar 430 is installed between the first link 410 and the second link 420, and the stability is improved.
