Baby Bath Tub

This invention relates to bathtubs, especially to bath tubs used to bathe infants and toddlers.

Baby bath tubs are conventionally horizontal, where infant is placed on back in laying position while washing him/her.

Parent can take baby to shower with him/herself and have baby standing in bathtub beside him/herself.

Baby can stand in water and take support from the side of the tub. Baby feels her/himself lighter in water and is encouraged to stand. If the baby loses balance the vertical walls will support her from falling.

Further embodiment provides an extension capability. The height of the bathtub can be adjusted to the height of the child. Adjustable height makes the tub more secure and more enjoyable for a child.

FIG. 1 shows a preferred embodiment of a bath tub. The tub is cylindrical; having a circular bottom 10 and vertical wall 12. The diameter of the tub is preferably between 20-30 cm. In general, the height should be at least 1.5 times the diameter of the bottom. Preferred height is to chest level 24 (FIG. 5). Minimum height is waist level 26. The diameter of the bath tub shouldn't be less than knee length. Too tight tub might cause jamming to the tub and drowning. Maximum straight standing diameter of the tub is reached when user stands in upright position buttocks touching the wall behind her/him and hands are straightened and the grip is comfortable from the upper edge of the tub. Best diameter/height combination area is highlighted by dots. In this area hands are kept straight, buttocks touch the wall and knees have enough room.

The tub is preferably made out of polymeric material. Different methods can be used, but preferably it should made by extruding.

The bottom of the tub can have anti-slippery treatment to prevent the tub from moving.

It can also be fixed to the bottom of a shower stall by one or more suction cups or other known manner.

The bottom of the tub can also have a layer, which adjusts itself to follow the contour of the ground where it is standing.

When the child is holding herself up against the wall in front of her, she/he is able to touch the wall behind her/him with her buttocks (FIG. 5). The knowledge of support behind her encourages her to release her hands and stand in upright position without hand support.

This confidence building and experience facilitates the child's experimentation with standing and walking.

Resistance from the water slows down movements making the early attempts at standing more fluid. Thereby what might be sudden jerky movement in the air is more controllable and smoother in the water. The buoyancy created by the water offers a child the chance to practice standing more easily and earlier in the water, because the muscles have less weight to support.

Also, a child of this age often prefers to test their new abilities and therefore does not like to be laid down and bathed in a traditional tub. A happy baby is easier to wash.

The bathtub is filled with water and child is placed to stand in the tub. The wider the tub bottom, the more difficult it is for a child to tip it over. The more there is water in the tub, the more secure it will be.

The chest level height walls prevent a child from leaning out of the tub and moves the equilibrium point of the tub-water-child combination outside of the vertical walls. High walls also prevent a child from jumping out of the tub unexpectedly.

The top of the chest level high walls provides a child an armrest where he/she can lean.

FIG. 2 shows an embodiment having an extended bottom part 14. The extension prevents the tub from falling if the child leans over the wall 12. The extension can be extruded and thus an integral part of the tub or it can be made separately from preferably softer, flexible material, which would follow the contour of the bottom of the shower stall or bathtub where it is placed.

FIG. 3 shows a third embodiment, having telescoping walls. The wall is made out of two parts: one part slides over the other. By moving the upper part the height of the tub can be adjusted to a desired level.

The bathtub can have a silicone rubber gasket 22 between the upper and lower wall preventing the joint from leaking. Preferably the parts can be secured on the selected level so the if the child leans on the wall, it doesn't slide down.

FIG. 4 shows an adjustable height bathtub. By moving the upper part the water level can be adjusted to desired level. One can move the upper part by turning the adjustment ring 20. Ring has a threads on inner rim. The counter part of the thread is in on outer surface of the wall extension 16.
