BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottom structure for a bed in which strip-shaped floorboards can be held at different heights by placing different surfaces as upper surfaces and the elasticity of the floorboards can be changed. It is a thing.

[0002]

2. Description of the Related Art The bottom of a conventional bed consists of a flat plate, a plate formed by pressing a steel plate, a steel wire stretched in a grid on a frame member, and , There is a steel wire formed in a net shape. Each of these bottoms has a different elasticity, but this elasticity greatly affects the comfort of the bed.

By the way, since the body surface of the human body is not flat, the pressure received from the mattress differs depending on the part of the body. For example, it is known that the parts of the back that receive the highest pressure are the scapula part A and the sacrum part B (see FIG. 5). Since such a portion is likely to be congested and cause pressure ulcers, it is necessary to eliminate body pressure by occasionally turning over and so on.

[0004]

However, in the bottom structure as described above, the body pressure distribution to the back is related to the unevenness of the body surface as described above, and the shoulder scapula part A and the sacrum part B are inevitably unevenly distributed. This will result in concentration.
The present invention has been made in view of such a problem, and provides a bottom structure in a bed that is configured to be able to partially change the elasticity of the bottom to improve sleeping comfort and also effective in suppressing pressure ulcers and the like. The purpose is to do.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a bed with a floor bottom,
Divided into multiple parts, each bottom is
Through the floor board holding members provided at regular intervals, strip-shaped
The floorboard is configured to be locked and held in the width direction of the bed, and the floorboard
The holding member has a locking frame that receives the floor plate.
Holds the floorboard so that it holds the different side as the top side.
Multiple steps formed at intervals corresponding to the widths of different faces of the plate
The floorboard is made of a hollow elastic body and has a
Has a plurality of longitudinal partition walls that define a number of spaces,
Along the circumference, along the long axis at eccentric positions of each surface
Has a rib, which is used as a locking frame for the floor plate holding member.
By locking it to the step in the
And hold it at different heights and change the elasticity of the floorboard.
Characterized in that way the.

[0006]

[Function] Among the plurality of ribs on the outer peripheral surface of the floor plate, the opposing ribs have the width of the floor plate of the locking frame of the floor plate holding member
The floorboards are retained by locking the steps formed at corresponding intervals, so by changing the placement of the floorboards, the floorboards are locked at different positions on the inner wall that narrows in a stepwise manner. However, the height of the floor board to be held changes. That is, depending on how to place the floor plate, the floor plate may be held in a protruding state. For example, by keeping the floor plate corresponding to other parts excluding the part corresponding to the scapula and the sacrum part higher, it is possible to suppress uneven distribution of body pressure distribution and improve sleeping comfort. Also, since the elasticity of the floorboard changes when the placement is changed due to the plurality of partition walls in the longitudinal direction that define a plurality of spaces inside, the floorboard is adjusted in combination with the change in the holding height to accommodate the body pressure distribution. Is possible.

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, the floor bottom 1 of the bed is divided into a back bottom 1a, a knee bottom 1b, and a leg bottom 1c.

The back bottom 1a, knee bottom 1b and leg bottom 1c respectively have strip-shaped floor plates 3 on the frame members 2a, 2b and 2c in the bed width direction and the frame members 2a.about.
It is configured to be locked and held by a floor plate holding member 4 provided at a predetermined interval on 2c.

The floor plate holding member 4 is a metal receiving member and has a locking frame 5 for receiving the floor plate 3, as shown in FIG. An inner wall of the locking frame 5 is formed in a stepped shape, and a plurality of step portions 6 and 7 for holding the floor plate 3 at different heights and different surfaces as upper surfaces are formed. These step portions 6 and 7 are provided below the step portion 6 located above.
Is in a position close to the center of the locking frame 5. The interval between the vertical walls 9 between the upper step 6 and the lower step 7 is substantially the same as one width (wider width) of the floor plate 3,
Also, the vertical wall 10 between the lower step 7 and the bottom 8
The space between them is formed to be substantially the same as the other width (narrower width) of the floor plate 3.

The floor plate 3 is made of an elastic material and is hollow, and is provided with a plurality of longitudinal partition walls 11 defining a plurality of space portions S therein as shown in FIG. On the other hand, ribs 12 along the major axis direction are provided at eccentric positions on the respective outer peripheral surfaces.

According to the above bottom structure, when the floor plate 3 is locked to the locking frame 5 of the floor plate holding member 4 with the surface having one width (wider width) as the upper surface, the space between the vertical walls 9 is The floor plate 3 is fitted to the floor plate 3, and the ribs 12 formed on the surface having the other width (narrower width) are retained by being locked to the step portion 6 (see FIG. 4a). Since the rib 12 is formed in an eccentric position, if the floor plate 3 is locked in the locking frame 5 in the opposite manner to the above, the floor plate 3 is held in a protruding state. (See Figure 4b). In this case, in the floor board 3,
Since the formation direction of the plurality of internal partition walls 11 is on the surface including the frame members 2a to 2c, the plurality of space portions S function as cushioning bodies and exhibit soft cushioning properties.

On the other hand, when the floor plate 3 is locked to the locking frame 5 of the floor plate holding member 4 with the surface having the other width (narrower width) as the upper surface, the floor plate 3 fits between the vertical walls 10 ( See Figure 4c). Further, when the placing method is reversed, the ribs 12 hold the projecting state (see FIG. 4d). In this case, the forming direction of the partition wall 11 is perpendicular to the surface including the frame members 2a to 2c.
Since it is (the direction in which the load is applied), the partition wall 11 functions as a pillar member, and a hard cushioning property is exhibited.

As described above, since the holding height and elasticity change depending on the placement method, for example, the floor plate 3 corresponding to other parts except the scapula and the sacrum part.
By keeping the height higher, uneven distribution of the body pressure distribution can be suppressed and the sleeping comfort can be improved. Furthermore, when combined with a change in elasticity of the floor plate 3 and a change in holding height, adjustment corresponding to the body pressure distribution becomes possible, and uneven distribution of the body pressure distribution can be corrected, so that sleeping comfort is significantly improved, It is possible to suppress the development of pressure ulcers.

[0014]

[Effects of the Invention] As described above, according to the present invention, the holding height and elasticity change depending on the placement method. Therefore, when combined with the change of the floor plate elasticity and the holding height, it corresponds to the body pressure distribution. Since such adjustment can be performed and uneven distribution of body pressure distribution can be corrected, there is an effect that sleeping comfort is significantly improved and the occurrence of pressure ulcer can be suppressed.
