It is AA sectional drawing of the bed shown in FIG. (A) is a front view of a movable plate, (b) is a plan view of the movable plate. (A) is a longitudinal cross-sectional view which shows the vertical relationship of a movable plate, (b) is a longitudinal cross-sectional view which shows the vertical relationship of a bar. It is a perspective view of the chair which is a modification of this embodiment.

  Here, a form for carrying out the present invention (hereinafter referred to as “the present embodiment”) will be described with reference to the drawings. Here, a bed is given as an application example of the body placement device.

(Schematic structure of the bed)
As shown in FIGS. 1 and 2, the bed 1 includes the support frame 3, the support piece 5, the cushion material 7, and the movable plate 9 as essential members, and the leg portions 4 as optional members. Each member is entirely made of wood except for the cushion material 7. The cushion material 7 will be described later. In FIG. 2, only the cushion material 7 is shown with hatching.

(Structure of support frame and support piece)
The support frame 3 is formed by combining two thick plates (long plates 3a, 3a and short plates 3b, 3b) having the same height and different lengths into a rectangular shape (see FIG. 1). A square member to be the support pieces 5 and 5 is fixed to the inner lower end of each 3a (see FIG. 2). Each support piece 5 has substantially the same length as each long plate 3a, and its height is lower than that of the long plate 3a. As a result, the support pieces 5 and 5 are supported by the support frame 3 and spaced apart in the width direction of the support frame 3. Although the number of the support pieces 5 is two, one or two or more support pieces may be arranged between them.

(Cushion material structure and material)
As shown in FIG. 2, a cushion material 7 having the same width and length as the upper surface is attached and fixed to the upper surface of each support piece 5. The cushion material is made of an elastic member (elastomer material) such as a urethane material. That is, the cushion material 7 is formed of a member that is deformed when receiving an external force and can return to its original shape when the external force is removed. The height of the cushion material 7 is determined in consideration of the movable plate 9 described later.

(Movable plate structure)
First, the single movable plate 9 will be described (see FIGS. 1 to 3). The movable plate 9 is a thick plate having the same length as the distance between the long plates 3a and 3a. The movable plate 9 is formed with a notch 9h penetrating in the vertical direction with the height direction being vertical (see FIG. 3B). The notch 9h seen from above has a long shape extending in the length direction except for both end portions of the movable plate 9. By forming the notches 9h, protrusions 9a and 9a are formed at both ends of the movable plate 9 viewed from above. As shown in FIG. 2, the movable plate 9 is stretched over the cushion members 7, 7 and is placed in parallel in a state of being in close contact with the longitudinal direction of the support piece 5 as shown in FIG. 1.

(Influence on the body)
Mattresses and futons have cushioning properties. When a mattress or the like is used on the place where the body of the general bed is placed, pressure is applied to the place where the body is placed and sinks, and the surrounding part (that is, the body is not placed) follows the place where the pressure is applied. Sinks to the part). Further, when a smooth and hard member such as between the plates is used at the place where the body of the bed is placed, the pressure concentrates on the head, back, buttocks and the like. Due to the sinking of the surrounding parts such as the mattress and the concentration of pressure on the head, the normal bending of the body cannot be maintained, the bending of the bending and the distortion of the body occur, and the waist is damaged. there is a possibility.

(Operation of cushion material and movable plate)
In order to solve the problem of the general bed described above, the bed 1 uses the cushion material 7 and the movable plate 9. That is, due to the elasticity of the cushioning material 7, the movable plate 9 sinks against the restoring force of the cushioning material 7 when the weight of the body part is added, and returns to the original position by the restoring force when the weight is removed. Return. The movable plates 9 are independent of each other, and form irregularities according to the weight and shape of the body 20 indicated by a two-dot chain line in FIG. (In FIG. 4 (a), the cross section of the movable plate 9 is shown without hatching.) Further, the movable plate 9 is used with its height direction being vertical (FIGS. 1, 2 and 4 (a)). (Refer to the above) That is, by using the cushion material 7 and the movable plate 9, it is possible to form unevenness according to the body 20, bend easily, and obtain an appropriate cushioning property. Sleeping comfort can be realized.

  The movable plates 9 placed in parallel in close contact with each other have a notch 9h as shown in FIGS. 3A and 3B, so that the movable plate 9 can be ventilated up and down. Thereby, it is possible to prevent and remove the wetness of the placed body 20 and the stuffiness of the placed futon. Furthermore, since moisture and the like are hardly confined, generation of ticks and odors can be prevented, which is good in terms of hygiene. Moreover, a clearance gap is made between the floor and the support piece 5 by using the leg part 4, and air permeability can be improved further.

  Since the movable plates 9 arranged in parallel form irregularities according to the weight and shape of the body 20 and have the notches 9h, they are placed on the movable plate 9 compared to a smooth surface. Mattresses and futons are less slippery than ordinary beds. This is because the mattress and the like together with the movable plate 9 form irregularities according to the weight and shape of the body, and the mattress is pushed into the notch 9h of the movable plate 9.

(Modification of movable plate)
Instead of the movable plate 9, a bar 10 as shown in FIG. 4B can also be used. (In FIG. 4 (b), the cross section of the bar 10 is shown without hatching.) The material of the bar 10 is not limited, but for example, round or square material such as wooden or metal that does not bend easily. The bar 10 can be used. The bar 10 is supported by each support piece 5 via the cushion material 7. The bars 10 are independent of each other, and form irregularities according to the weight and shape of the body 20 indicated by a two-dot chain line in FIG. Thereby, it can be used similarly to the movable plate 9. Further, in order to allow ventilation like the movable plate 9, a spacer (not shown) allowing vertical movement can be inserted between the bars 10.

(Function of bar)
As described above, the bar 10 sinks against the restoring force of the cushion material 7 when the weight of the body 20 is added, and returns to the original position by the restoring force when the weight is removed. Since each bar 10 is independent of each other, unevenness is formed by the weight and shape of the body 20, and an excessive burden is not imposed on the body 20, thereby realizing a good sleeping comfort. Further, as described above, by using a spacer (not shown) between the respective bar members 10, gaps are generated between the respective bar members 10, so that the upper and lower portions of the bar member 10 can be ventilated through the gaps. Thereby, it is possible to prevent and remove the wetness of the placed body 20 and the stuffiness of the placed futon. Furthermore, since moisture and the like are hardly confined, generation of ticks and odors can be prevented, which is good in terms of hygiene. From the point mentioned above, it can be used similarly to the movable plate 9.

(Modification of this embodiment)
The support frame 3, the support piece 5, the cushion material 7, and the movable plate 9 described above can be used not only for the bed 1 but also for the chair shown in FIG. The support frame 3 ′, the support piece 5 ′ (not shown), the cushion material 7 ′ (not shown), and the movable plate 9 ′ are structured with the support frame 3, the support piece 5, etc. used in the bed 1 shown in FIG. The action is not changed. Therefore, detailed description is omitted as much as possible. By using the cushioning material 7 'and the movable plate 9' etc. for the chair, unevenness is formed in accordance with the unevenness of the buttocks, etc., and an appropriate cushioning property is obtained, so an excessive burden is not applied to the buttocks, Good sitting comfort can be realized. Moreover, it is possible to prevent and remove the stuffiness caused by sitting for a long time.
