[0004]

[Problems to be solved by the device]

 Since the guide shaft 5 of the conventional example is largely separated from the column 4 above and protrudes outward, the hand is caught in the gap between the column and a part of clothes (for example, an apron string) is entangled. There is an accident that occurs, and there is a risk of collision with the protruding portion of the guide shaft 5, which is dangerous. Further, when a large number of beds are installed side by side in a kindergarten or the like, the beds cannot be brought close to each other due to the protruding portion of the guide shaft 5, and a wide space is required.

[0005]

[Means for Solving the Problems]

 This invention eliminates these inconveniences, that is, it has a fixed peripheral frame surrounding the bed and an elevating peripheral frame, and the elevating peripheral frame described above is guided by a guide shaft attached along the column. In an ascending / descending pediatric bed, the guide shaft is brought into close proximity to the support post in parallel, and guided members that are externally inserted to the guide shaft and ascend / descend are attached to both ends of the elevating / lowering peripheral frame, and are normally spring-loaded A pair of left and right protruding pins are provided so as to be retractable from both ends of the horizontal lower frame of the elevating and lowering peripheral frame, and the operating portion of each pin is provided below the upper edge of the horizontal lower frame to raise and lower the When the peripheral frame is raised, the pin projects and is inserted into the hole of the guide shaft.

[0006]

[Action]

 When the operating frame of each pin is moved against the spring pressure while the elevating peripheral frame is raised and surrounds the bed, each pin is disengaged from the hole of the guide shaft. If the elevating peripheral frame is pushed down here, the guided member is guided by the guide shaft, and the elevating peripheral frame descends. When the hand is released from the operating portion during the lowering, each pin is biased in the protruding direction by the spring pressure, but the protruding end of the pin is lowered together with the elevating peripheral frame while being in contact with the guide shaft.

On the contrary, when the elevating and lowering peripheral frame is lifted, each pin meets the hole of the guide shaft, and each pin is automatically inserted into the hole by the spring pressure, and the elevating and lowering peripheral frame surrounds the bed. is there .
