Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved bottom which can be bent only in one direction at a plurality of positions on a bottom of a gatch bed or the like so that the bending position can be easily adjusted. The present invention relates to a bottom structure capable of adjusting a knee apex position, which is adapted to a flexion / extension portion of a body which varies in position depending on a physique.

[0002]

2. Description of the Related Art In recent years, gatch beds have been widely used for hospitals and homes. In such a gatch bed, although not shown, for example, the bottom divided into a back bottom, a waist bottom, a knee bottom, and a foot bottom is raised or raised by a bottom raising / lowering mechanism, and each is adjusted to a desired inclination angle. It is configured as follows.

[0003]

However, in practice, it is rare that the joint of the user's body and the bent portion of the bottom match. For example, when using a bed with a relatively short height, if the user's waist is to be aligned with the bent part from the back bottom to the waist bottom, the knee sole will be bent at the bent part from the knee bottom to the foot bottom. If the position of the joint does not match, and if you try to adjust the position of the knee sole joint to the bent part from the knee bottom to the foot bottom, the bent part from the waist part and the back bottom to the waist bottom will not match . In addition, displacement of the body to the foot side due to raising the back is large. The present invention has been proposed in order to improve such inconvenience, the bottom of the gatch bed and the like,
A knee with a curved bottom configured to be able to bend only in one direction at a plurality of locations, so that the bending position can be easily adjusted, and adapted to the flexion and extension of the body depending on the user's physique. It is an object of the present invention to provide a bottom structure capable of adjusting a vertex position.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a curved bed in which a knee bottom and a foot bottom are connected so that a plurality of strip-shaped bottom members are bent only to one side. It is configured to be connected by a bottom, and is switched and held on the back side of the curved bottom so as to contact the back side of the strip-shaped bottom member from the center side to the end face side near the knee bottom and the end face side near the foot bottom of the curved bottom. Then, by constraining the strip-shaped bottom from the center to the end face closer to the knee bottom and the strip-shaped bottom from the center to the end face closer to the foot bottom one by one, the entire curved center was changed. , A switching restraining means is provided.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of a bottom structure capable of adjusting a knee apex position according to the present invention will be described with reference to the accompanying drawings. In FIG. 1, a bottom of a gatch bed (not shown) is provided between a knee bottom (described later) for supporting a thigh and a foot bottom (described below) for supporting a shin, and only one side is provided at several places during a knee raising operation. 1 shows a curved bottom 1 configured to be bent.

The curved bottom 1 is located on the upper surface (back surface) in the drawing.
It has a long box frame shape with open sides, that is, a structure in which a plurality of strip-shaped bottom members 2 are sequentially connected. These strip-shaped bottom members 2 are not shown, but have a cross-sectional shape.
For example, a trapezoid in which the upper surface side in the drawing, that is, the back surface side of the strip-shaped bottom member 2 is made narrow, and the curved bottom 1 is connected so as to be bent sequentially so that the front surface side is convex.

The plurality of strip-shaped bottom members 2
On the back surface of the strip-shaped bottom member 2 located at the center, the mounting bases 4 and 4 are protruded from the pair of horizontal ribs 3,
A U-shaped shaft member 5 serving as a switching restraining means is rotatably mounted between the mounting bases 4 and 4. The U-shaped shaft member 5 includes a vertical axis portion 5a having a base mounted on the mounting bases 4 and 4 and crossing the plurality of strip-shaped bottom members 2 so as to be orthogonal to the longitudinal direction of the strip-shaped bottom members 2. The base portion 4 has a horizontal shaft portion 5b which is pivoted about the center of the bottom portion 4 and reaches the end surface side of the strip-shaped bottom member 2 at the end located near the knee bottom and the foot bottom.

[0008] Further, of the plurality of strip-shaped bottom members 2, the strip-shaped bottom member 2 at the end located near the knee bottom and the foot bottom is protruded from the end face side of the strip-shaped bottom member 2. Stoppers 6, 6, and the horizontal shaft portion 5 b of the U-shaped shaft member 5 is provided on the stopper 6.
Is locked.

The bottom structure capable of adjusting the apex position of the knee according to the present invention is as described above. Therefore, when the user is relatively short, the U-shaped shaft member 5 is turned with the bottom flat. The horizontal shaft portion 5b is engaged with the stopper 6 of the strip-shaped bottom member 2 located near the foot bottom 10. Thereby, the strip-shaped bottom member 2 on the center side is formed.
, The strip-shaped bottom member 2 from the foot bottom 10
Since the longitudinal axis portion 5a of the U-shaped shaft member 5 abuts on the back surface, the rectangular bottom member 2 from the central rectangular bottom member 2 to the foot bottom 10 is in a restrained state. When the knee raising operation is performed, the curved bottom 1 is bent upward in the figure around the strip-shaped bottom member 2 near the knee bottom 11, as shown in FIG. If the user's knee joint position matches this curved position, the user's body, especially the lower body, can be suppressed from being pressed or displaced from the bottom, making it a comfortable holding bed with less discomfort. be able to.

On the other hand, when the height of the user is relatively high,
In a state where the bottom is flattened, the U-shaped shaft member 5 is turned to lock the horizontal shaft portion 5b with the stopper 6 of the strip-shaped bottom member 2 located near the knee bottom 11. As a result, the strip-shaped bottom member 2 on the center side abuts on the back surface of the strip-shaped bottom member 2 near the knee bottom 11 so that the longitudinal axis portion 5a of the U-shaped shaft member 5 crosses. From the bottom member 2 to the knee bottom 1
The strip-shaped bottom member 2 approaching one side is in a constrained state, and if the knee raising operation is performed in this state, the curved bottom 1 becomes
As shown in FIG. 3, it is curved upward in the figure around the strip-shaped bottom member 2 near the foot bottom 10.

[0011]

According to the present invention, on the back side of the curved bottom, the switching restraining means is applied to the back side of the strip-shaped bottom member from the center side to the end side near the knee bottom and the end side near the foot bottom of the curved bottom. Switch and hold so that it touches,
Used by restricting the strip-shaped bottom from the center side to the knee bottom end side end face and the strip-shaped bottom from the center side to the foot bottom side end face side by side, and changing the entire curve center point It is possible to sufficiently follow the displacement of the flexion and extension of the body due to the difference in the physique of the person, to eliminate the feeling of pressure on the body, and to provide high comfort.
