Detailed Description

Referring to fig. 1 to 4, a liftable infant bed according to an embodiment of the present application includes a base 1 preferably horizontally disposed and side uprights 2 vertically disposed at both ends of the base 1, and the base 1 and the side uprights 2 at both ends are formed in a substantially U shape. The liftable infant bed further comprises a first frame 3 and a second frame 4 arranged between the side uprights, the second frame being vertically higher than the first frame, the first frame being liftable with respect to the side uprights. The first frame and the second frame together form a bed. Specifically, the second frame is configured as an upper surrounding pipe of the bed body, and the first frame is configured as a lower surrounding pipe of the bed body. A bed plate and/or a mattress may be provided on the first frame, the bed plate and mattress being for supporting an infant. Between said first frame and said second frame a shield made of a flexible material 32, such as soft cloth or gauze, is arranged, which does not affect the lifting of the first frame and provides protection for the baby. A resting space for the infant is formed by the first frame, the second frame and the flexible material. It is also possible to first place a flexible material on the first frame and then place the bed plate and the mattress on top of the flexible material. For example, a flexible material is fitted over the first frame to form a cloth pocket over which the bed board and mattress rest.

The first frame can be provided with a table plate, and the table plate can be used as a learning table plate for children after the infants grow into children, so that the functions of the liftable infant bed are expanded, and different requirements from the infants to the children are met.

The second frame can be fixedly connected with the side upright post and fixedly used as an upper surrounding pipe of the bed body. Of course, the second frame is also configured to be partially removable with respect to the side posts, or completely removable with respect to the side posts, and may be conveniently removed when not needed. For example, when the baby is large enough and does not need the crib (for example, a child over 4 years old), the second frame can be partially or completely detached, and then the table plate is arranged on the first frame, so that the function of the liftable table can be realized by the liftable crib, and the learning requirements of the child can be met.

In the liftable crib according to the application, a stable supporting structure is provided for the crib through the side columns 2 and the first frame and the second frame which are arranged between the side columns 2. By arranging the first frame to be able to rise and fall relative to the side uprights, the crib can be adjusted to different heights as required. Can meet the height requirements of infants (or children) of different ages and is convenient for adults to take care of the infants. Furthermore, relative to the design scheme of the overall movement of the bed body, the baby bed is adjusted only by adjusting the first frame, so that the center of gravity of the baby bed is lower on one hand, and the bed body cannot rise too high on the other hand.
