A pair of each side surface 24b and a pair of side surfaces 24a are provided on both sides of the through hole 26, and a total of twelve rollers 36 are provided. Each roller 36 protrudes to the outer surface of the side surfaces 24a and 24b and rolls in contact with the inner surface of the side surfaces 18a and 18b when entering the inside of the lower frame member 16 so that there is no friction and allows the upper frame member 15 to move up and down. To guide.

  Next, the bed main body 12 provided on the base 14 will be described. The bed body 12 is provided with a rectangular plate-like floor plate 38 that is placed on the upper end portion of the upper frame member 15. The floor plate 38 has a rectangular shape that is slightly larger than the opening at the upper end of the upper frame member 15, and a fence 40 provided at a constant height above the floor plate 38 is provided around the periphery of the floor plate 38. ing. Part of the fence 40 is a fence door 40a that slides up and down. A cover 42 is provided around the periphery of the floor plate 38 so as to make a full circle. 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. When the bed main 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. 2, the lower end portion of the cover portion 42 is not attached to the floor, and the upper frame member It will not hinder the 15 descent. Moreover, even if the upper frame member 15 is slightly raised as compared with the state indicated 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 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. Yes. On one surface of the cover portion 42, a protrusion 48 is provided on the outer surface. The protrusion 48 is to be held when the bed body 12 is swung up and down, and is provided in an elongated horizontal direction so that it can be reached even when the childcare person sits on the floor or lies on the floor. It is provided at a position near the lower end.

  Next, the usage method of 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 main body 12 is lowered. Since three coil springs 34 are equally provided at both ends in the longitudinal direction of the upper frame member 15, the bed main body 12 does not tilt and the floor plate 38 is lowered while maintaining the level, and then the coil spring 34 is coiled. The spring 34 contracts and rises. When the swinging operation is stopped, the bed main body 12 repeatedly swings up and down by the elastic force of the coil spring 34 for a while, and then the swinging gradually converges and stops at the original position shown in the actual battle of FIG. Moreover, rocking | fluctuation can be continued by pushing the bed main body 12 according to the rocking | fluctuation timing. Since the coil spring 34 repeatedly swings and swings, the swinging 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. Infants can feel comfortable pitching. 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. When the weight of the infant 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 urging force is weakened, the amplitude of the bed main body 12 becomes too large, so that an appropriate urging force is set.

  When the baby is put in and out, 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 rocking baby bed 10 of this embodiment, it can be rocked up and down easily and easily with a weak force. Gives the infant a comfortable pitch 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 base 14 that swings the bed main body 12 slides with the upper frame member 15 projecting and retracting into the opening 22 of the lower frame member 16, but the opening 22 and the upper frame member are covered by the cover 42 of the bed main body 12. Since 15 is covered and the outer side is simple, there is no risk of objects being caught and broken, fingers or the like being injured, and the childcare person who is likely to attach to the infant is also safe. 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 cannot be touched from the outside, there is no risk of injury or destruction by touching with a finger or the like.

  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. Can be changed as appropriate, and the number of coil springs can be changed as appropriate, and may be replaced with 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 be other than a large rectangular shape, or may be a slit shape that is long in the vertical direction. The shape and attachment position of the protrusions held when swinging can be changed, and the means for stopping the swing may be other than the pin.
