Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor undulating mechanism and a floor structure in a bed which can suppress a feeling of pressure when raising the back.

[0002]

2. Description of the Related Art Recently, many beds have a structure for undulating a floor, and various beds are used. By the way, in the structure of a normal bed, the back bottom and the waist bottom are simply connected, and the undulating motion is performed by using the connecting portion here as a pivot of the floor.

[0003]

However, in such a structure, when the back is raised, the vicinity 2 of the bent portion of the floor 1 is narrowed so as to approach the front, and as a result, the patient feels that the body is displaced. At the same time, a feeling of pressure is felt in the waist and abdomen (see FIG. 9). Therefore, as a means for improving these inconveniences, it may be considered to apply a mechanism for moving the bent portion vicinity 2 toward the head side when raising the back so as to correct the space narrowed by raising the back. To be The present invention has been made based on such a viewpoint, and secures an appropriate space in the vicinity of the connecting portion between the back bottom and the waist bottom when raising the back, and the floor undulating mechanism in a bed without feeling of pressure and It is intended to provide a floor structure.

[0004]

In order to solve the above-mentioned problems, the present invention divides a floor portion into a back bottom, a waist bottom, a knee bottom and a leg bottom, and forms a plurality of the back bottom and the waist bottom. with a linked structure by bottom strips of the knee bottom and foot bottom and ligated composed of a plurality of bottom strips, back lifting and Hizajo the floor below

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a floor undulating mechanism and a floor structure in a bed according to the present invention will be described below with reference to the accompanying drawings with reference to an embodiment. In FIG. 1, reference numeral 10 indicates a bed floor portion 10.
Is divided into a back bottom 11, a waist bottom 12, a knee bottom 13 and a leg bottom 14, and the back bottom 11, the waist bottom 12, and the knee bottom 13 and the leg bottom 14 are a plurality of strip-shaped bottoms 15, 16. The structure is linked by.

As shown in FIG. 2, a bed main body (not shown) below the floor 10 is provided with an activation unit 17 for raising the back and knees, which constitutes a floor undulating mechanism, and is provided below the waist bottom 12. Is provided with a guide frame 18 in the horizontal direction. The activation unit 17 is provided with a back raising arm 19 for raising the back and a knee raising arm 20 for raising the knee.

In the floor undulating mechanism as described above, the back raising arm 19 abuts on the lower surface of the back bottom 11 via the rollers 21 and 22, and the knee raising arm 20 is a connecting portion with the knee bottom 13 and the leg bottom 14. It is in contact with a plurality of strip-shaped bottoms 16 via rollers 23. The waist bottom 12 is movably supported by the guide frame 18 via a holding roller 24. Further, a protruding frame 25 extends below the waist bottom 12 and is connected to a short arm 26 integral with the back raising arm 19 via an interlocking arm 27.

The strip-shaped bottom 15, which is a connecting portion between the back bottom 11 and the waist bottom 12, is connected to the upper surface of the back bottom 11 so as to be bendable within a predetermined range by an appropriate connecting member (for example, a leaf spring). (See FIG. 3). Further, the plurality of strip-shaped bottoms 16 that are the connecting portions with the knee bottoms 13 and the leg bottoms 14 are configured to be bendable at a predetermined angle on the lower surface side of the strip-shaped bottoms 16. The strip-shaped bottoms 15 and 16 are made of plywood of known material,
Any of blown material, extruded material and the like can be applied.
In addition, hollow strip-shaped bottoms 15 and 1 as shown in FIG.
The 6 may be connected to each other by a tenon 28 and a mortise.

In the interlocking arm 27, a shaft member 29 attached to the end of the projecting frame 25 has a slot 30 near the end of the interlocking arm 27.
Is provided, and the interlocking arm 27 is configured so that the shaft member 29 can slide within the range of the elongated hole 30 (see FIG. 5).

The floor undulating mechanism and the floor structure of the bed according to the present invention are constructed as described above, and the operation will be described below. When the activation unit 17 is activated to raise the back, the back raising arm 19 moves the back bottom 1
The back bottom 11 rises while rotating while being in contact with the lower surface of the 1. Along with this, the strip-shaped bottom 15 between the back bottom 11 and the waist bottom 12 bends so as to form a large radius of curvature. Further, when the back raising arm 19 is displaced, the interlocking arm 27 is displaced toward the back bottom 11 side so as to be retracted. In this case, until the back is raised to a certain extent, the interlocking arm 27 is simply displaced until the shaft member 29 at the end of the protruding frame 25 reaches the end of the elongated hole 30 (see FIG. 6), and the waist bottom 12 is initially moved. Position (see FIG. 7). Further, when the back bottom 11 gets up, the end of the long hole 30 of the interlocking arm 27 comes into contact with the shaft member 29, and the waist bottom 12 is pulled toward the back bottom 11 side by the interlocking arm 27, so that the roller 14 moves.
Rolls on the guide frame 18 and the waist bottom 12 moves toward the back bottom 11 (see FIG. 8). As a result, the strip-shaped bottom 15 at the position for holding the waist of the patient moves to the back bottom 11 side so as to be retracted, so that it is possible to correct the narrowing of the space due to raising the back, and an appropriate space is secured. Thus, it is possible to avoid pressing the patient's waist from the back bottom 11 by raising the back.

Further, the knees can be raised when raising the back as described above. That is, when the activation unit 17 is activated to displace the knee-raising arm 20, the strip-shaped bottom 16 that is the connecting portion between the knee bottom 13 and the leg bottom 14 bends so as to form a large radius of curvature. Therefore, the strip-shaped bottom 16 that is the connecting portion between the knee bottom 13 and the leg bottom 14 can be adapted to the knee joint regardless of the physical constitution of the patient.

[0013]

As described above, according to the present invention, a plurality of strip-shaped bottoms are bent to have a large radius of curvature, and the waist bottom is moved to the back bottom side in conjunction with the movement of the back bottom. By doing so, it is possible to correct the narrowing of the vicinity of the joint between the back bottom and the waist bottom due to raising the back, and to secure an appropriate space, so avoid pressing the patient's waist from the back bottom. can do. further,
Knee bottom and leg bottom form a large radius of curvature
With a plurality of strip-shaped bottoms that bend like this, it can follow the knee joints of the body regardless of the patient's physique and can hold the body sufficiently, making it a comfortable bed that does not feel misalignment .
