[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 a leg-side bottom is formed to be bendable with an appropriate curvature and the discomfort is small regardless of the size of the patient.

[0002]

2. Description of the Related Art In many modern beds, the bottom portion is divided into a back bottom, a waist bottom, a leg bottom, etc., and a drive mechanism is used to raise the back and raise the legs.

[0003]

[Problems to be Solved by the Invention] However, in the bottom structure as described above, the joint position between the waist bottom and the leg bottom does not match the knee position that differs depending on the size of the patient's body, and the leg is lifted. When you do, you may feel unreasonable. Therefore, it was necessary to prepare beds having different bottom division positions. The present invention has been made in view of the above problems, and an object thereof is to provide a bottom structure for a bed that has a structure that allows any patient to comfortably lift the legs while suppressing discomfort.

[0004]

In order to solve the above-mentioned problems, the present invention provides a curved bottom at a position corresponding to the vicinity of the knee of a human leg in the bottom of the bed, and the curved bottom is integrated. Is formed thinly, the surface on the upper side of the bottom is a flat surface, and a plurality of width direction ribs oriented in the bed width direction at predetermined intervals are formed on the surface on the lower surface side of the bottom. A vertical rib is formed so as to be orthogonal to the widthwise rib, and a cutout portion that expands downward toward the bottom is formed in the vertical rib at the intersection of the widthwise rib and the vertical rib. It is characterized in that it is configured to be curved so that the flat surface is a convex surface.

[0005]

When the leg is lifted, the notch in the longitudinal rib is deformed so as to be closed, and the curved surface on the upper side of the bottom is curved so as to be a convex surface. As a whole, it is gently curved with an appropriate curvature. . Therefore, even when the position of the back of the knee is slightly displaced from the curved bottom, which is a curved portion, the back of the knee is not pressed by the bottom, and the bed has less discomfort regardless of the size of the patient. be able to.

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. FIG. 1 shows a bed 1 having a bottom undulation mechanism (described later). In the bottom 2 of the bed 1, the curved bottom 3 is arranged between the bottom 2 corresponding to the thigh of the human leg and the bottom 2 corresponding to the calf to the foot, that is, at a position corresponding to the back of the knee. It is a thing. The actuating arm 5 that constitutes the undulating mechanism 4 of the bottom 3 is in contact with the lower surface of the curved bottom 3.

The curved bottom 3 is a thin-walled molded body integrally molded of, for example, a thermoplastic molding material, and notches 6 are formed at predetermined intervals on the end face of the bed 1 oriented in the width direction. (See FIG. 2). That is, in the curved bottom 3, the surface on the upper side of the bottom 2 is a flat surface,
The bottom surface of the bottom 2 has a plurality of width-direction ribs 7 oriented in the width direction of the bed 1 and vertical ribs 8 orthogonal to the width-direction ribs 7 at predetermined intervals. The notch 6 is formed at the intersection of the widthwise rib 7 and the lengthwise rib 8 on the lengthwise rib 8 side. The notch 6 is formed so as to expand downwardly of the bottom 2 (see FIGS. 3 and 4). Curved bottom 2 having such a configuration
Is connected to the bottom 2 corresponding to the thigh of the human leg and the bottom 2 corresponding to the calf to the foot by the connecting frames 9 and 10 on the side where the widthwise ribs 7 and the longitudinal ribs 8 are formed. (See Figure 5).

In the bottom structure as described above, when the leg raising mechanism is activated to raise the leg, the actuating arm 5 rises and pushes up the curved bottom 3 from the lower surface side of the bed 1. The notch 6 that expands downwardly of the bed 1 is deformed so as to close, and as a result, the curved bottom 3 is curved so that the upper flat surface of the bottom 2 is a convex surface, and as a whole, it is gentle and appropriate. Bends with various curvatures (see FIG. 6). Therefore, even when the position of the back of the knee is slightly displaced from the curved bottom 3 which is the curved portion,
The back of the knee is not pressed by the bottom 2, and the bed can be made to have little discomfort regardless of the physical constitution of the patient.

Further, as described above, since the curved bottom 3 is a thin-walled molded body integrally molded, it is easy to manufacture, and the widthwise ribs 7 and the longitudinal ribs 8 reduce the weight. Together with the required strength.

[0010]

As described above, according to the present invention, a bed having a high suitability can be obtained regardless of the size of the patient.
