Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottom structure in a bed in which the bottom is configured to be bendable with a large curvature so that it does not force when raising the back.

[0002]

2. Description of the Related Art Recently, many beds have a back raising mechanism, and various beds have been adopted.

[0003]

However, in the usual bed structure, the back bottom and the waist bottom are simply connected to each other, and the connecting portion here is a pivotal fulcrum of the back bottom, that is, in practice. As a fulcrum of, the undulating motion is performed. Therefore, when the back bottom gets up to a certain angle, the space near the connecting portion between the back bottom and the waist bottom narrows, and the patient's waist and abdomen are pressed by the mattress. The present invention has been made in order to solve such a problem, and has a bottom structure in a bed in which the bottom is configured to be bendable with a large curvature to secure a space at a bent portion of the bottom and suppress a feeling of pressure. The purpose is to provide.

[0004]

In order to solve the above-mentioned problems, according to the present invention, in a bed, the bottom is formed to be bendable by a plurality of strip-shaped bottoms, and the bottoms of the beds are connected to each other. It is characterized in that the width of the strip-shaped bottom on the bed upper surface side is shorter than the width on the bed lower surface side. Also,
The bottom is made of a hollow thermoplastic molding material, and the strip-shaped bottoms are integrally connected to each other on the bed lower surface side, and a gap is provided between the strip-shaped bottoms on the bed upper surface side. It is a thing.

[0005]

[Operation] When you raise your back, each strip bottom will
Since the beds are in contact with each other on the upper surface side, the bottom bends with a large curvature at the waist. Therefore, the space of the bent portion of the bottom is secured, and the feeling of pressure can be suppressed.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a bottom structure of a bed according to the present invention will be described below with reference to the accompanying drawings, with reference to an embodiment. As shown in FIG. 1, in the bed 1, a plurality of strip-shaped bottoms 3 are arranged in a portion corresponding to the position of the lower back of the human body so as to be bendable, and at the bottom side of the bed. The width of the strip-shaped bottom 3 on the bed upper surface side is shorter than the width of the strip-shaped bottom surface 3 on the bed lower surface side.

In the bottom portion 2, a strip-shaped bottom 3 is provided.
5 are provided and are made of a hollow thermoplastic molding material. As shown in FIG. 2, the strip-shaped bottoms 3 are formed in a substantially trapezoidal shape in cross section, the surfaces on the lower surface side of the bed are integrally connected, and on the upper surface side of the bed, the strip-shaped bottoms 3 face each other. The surface forms an angle of about 16 ° and a gap g is formed. Further, on the bottom surface of the bottom portion 2, a back raising mechanism 4 is motively connected via a support arm 5.

In the bottom structure as described above, when the back raising mechanism 4 is activated to raise the back, the supporting arms 5 are displaced, and the strip-shaped bottoms 3 abut each other on the bed upper surface side. Therefore, the bottom portion 2 bends with a large curvature (curvature radius R) toward the bed upper surface. As a result, the bottom portion 2 is bent by about 80 °, an appropriate space is secured in the waist portion, and a feeling of pressure due to raising the back can be suppressed.

Further, according to the present invention, the strip-shaped bottom 3 can be constructed as shown in FIG. In this case, the strip-shaped bottom 3 has a trapezoidal upper half in cross section.

Even with such a shape, since a gap g is formed between the strip-shaped bottoms 3 on the upper surface side of the bed, the entire body is bent with a large curvature by raising the back, and a proper space is provided in the waist. Is ensured and the bed is highly adaptable regardless of the height of the patient. Since the bottom part 2 is made of a hollow thermoplastic molding material, it is easy to process and has a simple structure, which is advantageous in terms of cost.

[0011]

As described above, according to the present invention, a comfortable bed can be provided without feeling the pressure caused by raising the back.
