## Abstract

A water bed crib comprising a water bed structure including a flat horizontal rectangular platform with an upwardly projecting mattress retaining, water draining weir about its perimeter, a water filled flexible mattress bladder supported atop the platform within the confines of the weir, platform legs at and depending from the four corner portions of the platform, floor engaging caster wheels at the lower end portions of the platform legs, crib frame legs supporting brackets projecting outwardly from the platform legs; a rectangular crib frame with vertical end boards and vertical side gates engaged about the water bed structure and having crib frame legs depending from its four corners and engaging the brackets on the platform legs; the crib frame legs have caster pintle receiving openings in their lower ends and the brackets have retaining pintles engaged in said openings.

## Claims

### Claim 1

A water bed structure comprising an elongate platform including a flat horizontal rectangular panel, a rectangular weir about the perimeter of and projecting upwardly from the panel and floor-engaging support structure below the platform; and a flexible flotation mattress in supported engagement atop the panel and retained within the weir, said weir including a wall structure about the panel defining a liquid conducting passage about the perimeter of the platform and including an outer jacket of soft resilient material about its exterior, liquid conducting ports in the wall structure communicating with said passage and the space inward of the weir and in which the mattress is arranged whereby water in said space flows through the ports and into said passage; and drain means to drain water from the passage.

### Claim 2 (depends on 1)

The water bed structure set forth in claim 1 wherein said drain means includes a water receptacle below the panel and a drain opening in the structure communicating with the passage to conduct water from the passage for delivery into the receptacle.

### Claim 3 (depends on 2)

The water bed structure set forth in claim 2 wherein the flotation mattress includes a resilient pad of reticulate material having a top plane which is above the plane of ports in the weir and a bladder of flexible plastic sheeting filled with water and having a top wall normally spaced above the pad or near the top plane of the weir.

### Claim 4 (depends on 1)

The water bed structure set forth in claim 1 wherein the flotation mattress includes a resilient pad of reticulate material having a top plane which is above the plane of ports in the weir and a bladder of flexible plastic sheeting filled with water and having a top wall normally spaced above the pad or near the top plane of the weir.
