Each roller 36 projects on the outer surface of the side surfaces 24a and 24b, and when it enters the inside of the lower frame member 16, it abuts against the inner surface of the side surfaces 18a and 18b and rolls, there is no friction, and the upper frame member 15 moves up and down Guide.

  Next, the bed body 12 provided on the base 14 will be described. The bed main body 12 is provided with a rectangular plate-like floor plate 38 placed on the upper end portion of the upper frame member 15. The floor plate 38 is a rectangle slightly larger than the opening at the upper end portion of the upper frame member 15, and a fence 40 provided at a certain height above the floor plate 38 is provided around the floor plate 38 in a circle. ing. A part of the fence 40 is a fence door 40 a that slides up and down. Below the peripheral edge of the floor plate 38, a cover 42 is provided around the circumference. The cover portion 42 is a rectangular cylinder that is assembled on four side surfaces and opens downward, and has a size that covers the upper frame member 15 and the lower frame member 16 of the base 14 with a slight space, and is perpendicular to the vertical direction. 2 is lower than the opening 22 of the lower frame member 16 when the bed main body 12 is placed on the base 14 and the coil spring 34 is slightly extended by its own weight as shown by the solid line in FIG. It is located in Then, when the bed body 12 is pushed downward and the coil spring 34 extends longer and descends most, as shown by the two-dot chain line in FIG. It does not interfere with the descent of 15. The upper frame member 15 has a length that covers the opening 22 even if the upper frame member 15 slightly rises from the state shown by the solid line in FIG.

  A pin 44 for stopping the swinging of the bed main body 12 is provided in the vicinity of the lower end portion of the cover portion 42, and an insertion hole 46 into which the pin 44 is inserted is provided on the outer surface of the lower frame member 16 of the base 14. There is. A protrusion 48 is provided on the outer surface of one surface of the cover portion 42. The projection 48 is used to hold the bed body 12 up and down, and is provided horizontally long and narrow so that the cover portion 42 can be reached even if the caregiver sits or lies on the floor. It is provided at a position close to the lower end.

  Next, a method of using the rocking baby bed 10 will be described. As shown in FIG. 2, with the bed main body 12 placed on the base 14, baby bedding is set on the floor board 38 and the baby is laid down. In order to make it fall asleep, the pin 44 is removed from the insertion hole 46 to make it free, and the childcare person who is likely to attach to the infant lightly pushes down the bed body 12. Then, the coil spring 34 of the base 14 is extended, and the bed body 12 is lowered. Since three coil springs 34 are provided equally at each end of the upper frame member 15 in the longitudinal direction, the bed body 12 does not tilt and the floor plate 38 descends while maintaining the level, and then the coil The spring 34 retracts and rises. When the rocking operation is stopped, the bed body 12 repeats rocking up and down by the elastic force of the coil spring 34 for a while, and the rocking gradually converges and rests at the original position shown in FIG. The rocking can be continued by pressing the bed body 12 at the rocking timing. Since the coil spring 34 swings repeatedly by extension and contraction, the swing is continued with a small force. Since the roller 36 slides while rolling in contact with the inner surface of the lower frame member 16, the upper frame member 15 is guided so as to swing linearly, and slides smoothly and stably without resistance. The infant can feel a pleasant pitching with this. In addition, since the sound generated when the roller 36 rolls and the bed main body 12 moves up and down is close to that of the human womb, the infant is relieved by hearing. If the weight of the baby is light, the number of coil springs 34 may be reduced. Moreover, it is preferable that the urging force of the coil spring 34 is set to be weak so that the childcare person can easily vibrate the bed body 12 with his / her hand. However, if the biasing force is weakened, the amplitude of the bed main body 12 becomes too large, so the biasing force is made appropriate.

  When putting in and out the baby, the fence door 40a is opened. When swinging is unnecessary, such as after an infant falls asleep, the pin 44 is inserted into the insertion hole 46 and locked, so as not to swing. Even if the childcare person sits down or lies down on the floor, the child can reach the protrusion 48 and can continue swinging in an easy posture.

  According to the swingable baby bed 10 of this embodiment, it is possible to swing up and down stably easily with a weak force. Gives the baby comfortable pitching and can be reassured. There are no sliding members around the baby, and there is no accident of pinching a finger or an object between the two sliding members, and safety is high. The upper frame member 15 slides on the opening 22 of the lower frame member 16 while the base 14 swings the bed body 12. However, the opening 22 and the upper frame member are covered by the cover 42 of the bed body 12. Because the outer surface is simple and covered with 15, there is no risk of an object being pinched and broken or a finger or the like being pinched and being injured, and it is safe for a child-caretaker to attach to an infant. The cover 42 is provided with a length that covers the opening 22 of the lower frame member 16 even at the position where the bed main body 12 is raised, and can reliably cover the opening 22. Since the coil spring 34 is provided in the space inside the base 14 and can not be touched from the outside, there is no risk that a finger or the like may be touched or injured or broken.

  The rocking baby bed of the present invention is not limited to the above embodiment, and the shape of each member can be freely changed, and the positions and widths of the upper mounting member and the lower mounting member to which the coil spring is attached. The number of coil springs may be changed as appropriate, and may be replaced with an elastic rubber or the like. The coil spring may be provided between the lower surface of the lower mounting member and the reinforcing member of the lower frame member, or may be compressed and rocked when descending. The through hole of the upper frame member may have a shape other than a large rectangular shape, and may have a slit shape which is long in the vertical direction. The shape and mounting position of the projection to be held when the rocking can be changed, and the means for stopping the rocking may be other than the pin.
