CONSTITUTION:A cushion 6 is placed on a cover member 5 of a bed. Here, a front end moving shaft 2 is located in contact with a front end of a frame body 1 so as to be at an initial position. A gap is left between a rear end side moving shaft 2 and a rear end of the frame body 1. Under such a condition, a person lays himself on the cushion 6. After about one hour, a motor 10 is driven with a switch to move the moving shafts 2 behind the frame body 1 with a driver 4. Then, as the rear end of a mobile support shaft 8 approaches the rear end of the frame body 1, a limit switch is activated with the mobile support shaft 8 and the motor 10 is halted. In this manner, the moving shaft 2 at the rear end is located contacting the rear end of the frame body 1 and a gap is left between the moving shaft 2 at the front end and the front end of the frame body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to a bed for bedridden elderly people, sick people, etc.

[Prior Art] Generally, bedridden elderly people, sick people, etc. are unable to move their bodies freely and lie in the same position on the bed for long periods of time, so the contact area between the bed and the body is always the same. , blood circulation in the area becomes poor, and in severe cases, bedsores may develop and even lead to destruction of the skin and subcutaneous tissue.

In view of this problem, conventionally, in this type of bed,
A structure in which a large number of vinyl air bags are laid out in the shape of a base has been proposed. Each of the air bags communicates with every other adjacent air bag. In other words, in this conventional bed, the air bladders are divided into two sets, and each set is inflated at the same time when air is injected, and deflated at the same time when air is let out. When in use, air is filled into the - set of air bags, and the body of a sleeping person is supported by the - set of air bags. After about an hour, the air in the negative set of air bags is let out and air is filled into the other set of air bags, and the body of the sleeping person is supported by the other set of air bags. By alternately changing the air bladders that support the sleeping person's body in this way, it is possible to change the contact position between the sleeping person's body and the bed.

[Problems to be Solved by the Invention] However, since conventional beds use air bags, the sleeping person's body is supported by a surface. As a result, the air bag and the sleeping person's body come into close contact, which may impair blood circulation in the area of the sleeping person's body that is in contact with the air bag.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a bed that can minimize the deterioration of blood circulation in the areas that come in contact with the bed, even if the patient lies in the same position for a long time.

[Means for Solving the Problem] In order to solve the above object, the present invention includes a frame body,
A plurality of moving axes are provided to the frame so as to be movable in a substantially horizontal plane; a plurality of support members are attached to the moving axes at a distance from each other, and each of the support members has a curved surface having an arcuate cross section on its upper surface; The gist of the present invention is to include a drive device that moves each moving axis relative to the frame.

[Function] The bed of the present invention is used by changing the position of supporting the sleeping person's body by moving the return axis, that is, the support member, for a certain period of time.

Further, since the support member has a curved surface having an arcuate cross section on the upper surface, it supports the body of a sleeping person in a line or point.

[Embodiment] Hereinafter, an embodiment embodying the present invention will be described with reference to FIGS. 1 to 7.

This movable support shaft 8 is movable in the longitudinal direction of the frame 1 by the casters 9 sliding on the guide rail 7, and one end of the movable support shaft 8 is configured to move in the direction of movement of the movable support shaft 8. An extending female screw hole 11 is formed. A motor 10 capable of forward and reverse rotation is provided on the left outside of the front part of the frame 1, and an insertion hole 13 extending in the longitudinal direction of the frame 1 is bored at the front end of both frame members 1a. . This insertion hole I3 has a size such that the end of the movable support shaft 8 can move therein. A male screw 12 facing the female screw hole 11 in the insertion hole 13 is connected to the motor shaft of the motor 10 . The male screw 12 is rotated by the operation of the motor 1O, and can be relatively screwed into and retracted into the female screw hole 11 of the movable support shaft 8.

When the male screw 12 screws into the female screw hole 11, the movable support shaft 8 moves toward the motor 10 (forward) (see Fig. 3), and when the male screw 12 screws back from the female screw hole 11, The movable support shaft 8 moves toward the side opposite to the motor 10 (rearward) (see FIG. 6). In addition, the guide rail 7, movable support shaft 8, caster 9, motor 10
, a female screw hole 11 and a male screw 12 constitute the drive device 4.

Moreover, as shown in FIG. 1.2.3, both the movable support shafts 8
A plurality of moving shafts 2 are installed between them in the lateral direction. As shown in FIG. 3, when the movable support shaft 8 is located at the initial position, there is a distance of approximately 30 cm between the rear end of the frame I and the movable shaft 2 closest to the rear end. It is being

A large number of wooden (paulownia wood) support members 3 are attached to each moving shaft 2 at a distance from each other. The support member 3 has a diameter of approximately 5
am, has a cylindrical shape with a length of about 2.5 cm, and the moving shaft 2 is inserted and fixed in the direction of its central axis. Note that the moving shaft 2 has a cylindrical shape with a diameter of about 1.5 cm. The spacing between the supporting members 3 attached to each moving shaft 2 is approximately 2.5 cm, and the supporting members 3 attached to the adjacent moving shafts 2 are positioned between each supporting member 3. It has become.

On the upper side of the support member 3, a thick cloth covering member 5 is firmly attached to the frame 1 so as to cover the upper surface of the frame 1. Further, the upper surface of the support member 3 is positioned so as to be in contact with the covering member 5.

Next, how to use the bed of this embodiment will be explained.

As shown in FIG. 2, a futon 6 is placed on the cover member 5 of the bed.
