Abstract

To provide a bottom for a bed apparatus that can make the user feel comfortable when lying on the bed apparatus. The bottom for a bed apparatus, which is height adjustable and is mounted on the top of a bed apparatus, comprising a plurality of parts each formed of a resin plate having a thickness, including a back bottom, a hip bottom, a knee bottom and a foot bottom. Of the parts, essential parts are joined by connecting parts, and the connecting parts are formed of the same material with, to be thinner than, and integrally with, the essential parts, and, depressed portions are formed on the top surface of the bottom around the center in the width direction of the bottom, and a plurality of passage holes are perforated in the depressed portions from the top surface to the undersurface of the bottom.

First claim

The invention claimed is:

1. A bottom for a bed apparatus, which is height adjustable and is mounted on the top of a bed apparatus, comprising:
a plurality of parts each formed of a resin plate having a thickness, including a back bottom, a hip bottom, a knee bottom and a foot bottom, wherein
a top surface of the hip bottom has flat areas and a depressed portion,
the depressed portion is formed in a central part of the hip bottom with respect to the width direction by forming the flat area respectively on both sides of the hip bottom with respect to a width direction of the bed apparatus,
the depressed portion is formed across a space between the flat areas being formed both sides of the hip bottom,
a passage hole is formed from the top surface in the depressed portion to an undersurface of the depressed portion, and
a flexing part is extended from the hip bottom, overlapping the back bottom, and flexibly joined to the back bottom so as to slide along the back bottom when a back-raising operation is carried out.

2. A bottom for a bed apparatus, which is height adjustable and is mounted on the top of a bed apparatus, comprising:
a plurality of parts each formed of a resin plate having a thickness, including a back bottom, a hip bottom, a knee bottom and a foot bottom, wherein
a top surface of the hip bottom has flat areas and a depressed portion,
the depressed portion is formed in a central part of the hip bottom with respect to the width direction by forming the flat area respectively on both sides of the hip bottom with respect to a width direction of the bed apparatus, wherein each flat area extends from the depressed portion in the width direction to the corresponding side of the hip bottom,
the depressed portion is formed across an entire space between the flat areas that are formed on both sides of the hip bottom, and
a passage hole is formed from the top surface in the depressed portion to an undersurface of the depressed portion.

3. The bottom for a bed apparatus according to claim 2 , wherein
the depressed portion is also formed respectively on the back bottom, the knee bottom and the foot bottom, and
the depressed portions of the bottom are formed so that the depressed portion of the hip bottom is the deepest, and the depressed portion of the knee bottom is the second deepest.

4. The bottom for a bed apparatus according to claim 2 , wherein the depressed portion is formed in dimensions corresponding to a width of a user body.

5. The bottom for a bed apparatus according to claim 2 , wherein a flexing part is extended from the hip bottom, overlapping the back bottom, and flexibly joined to the back bottom so as to slide along the back bottom when a back-raising operation is carried out.

6. A bed assembly including:
the bottom for a bed apparatus according to claim 2 , and
a mattress, wherein the top surface of the hip bottom faces the mattress.
