Description

[Detailed explanation of the idea] The present invention relates to a chair bed that can also be used as a chaise lounge.

FIG. 1 shows a conventional bed for bedridden patients to prevent bedsores, to change their mood, and for other purposes. The bed plates 3 and 4 are bent around the shaft 5, and the shaft 5 is raised.

The slide 2 is fixed by supporting the support plate 6 with a stopper 7.

Next, the bed plate 9 is raised around the shaft 8 incorporated in the slide 2, and the support plate 10 is supported by the stopper 11.

This structure is disadvantageous in that it requires the nurse's effort to raise the body, which increases the burden on the nurse.

The present invention is based on a study of commercially available welfare machines aimed at preventing bedsores, and a simple mechanism that allows the patient to sit up without requiring the effort of a nurse.

That is, the present invention provides a bed in which a part that supports the head and a part that supports the back are integrated (hereinafter referred to as the back part) and a part that supports the feet (hereinafter referred to as the foot part) can rotate. , the side walls that support the back and legs from the floor and are fixed at the head of the bed are approximately half the total length of the bed from near the patient's waist to the head; A nearly vertical guide into which the rollers of the back part are fitted and tilted backward toward the head, a nearly horizontal guide into which the layer-side rollers of the back part are fitted and which descend towards the head, and a mechanism to move the back part along the side wall. This chair bed is equipped with a mechanism in which the leg side of the section is supported by legs with rollers, and the tip of the leg section moves horizontally or in a downward direction from the back section along with the movement of the back section.

An embodiment of the present invention is shown in FIGS. 2 to 5. In FIG. 3, bed plates 21 and 22 and bed plate 2
2 and 23 are connected by shafts 24 and 25, respectively, and are bent around the shafts.

The side walls 26 and 27 in FIG.
It is fitted into the guide 28 of No. 7.

The side walls 26 and 27 are connected by a rear plate 30.

The side walls 26, 27 have a length of approximately half the total length of the bed from the vicinity of the patient's waist toward the head.

Both sides of the shaft 24 are fitted in near-horizontal guides 31 that run down towards the heads of the side walls 26 and 27.

Further, both ends of the shaft 24 are connected to a guide 31 by a motor 36 via a connecting plate 32, a chino 33, and a sprocket 34,35.
driven along.

Sprockets h 34, 35 and a motor 36 are installed on the side wall 27.

A foot 37 is fixed to the bed board 22, and a roller 38 is attached to the lower end of the foot 37, and is in contact with a floor 39.

A support plate 40 is attached to the leg 37 and reinforced by a reinforcing plate 41.

The support rod 42 rotates around a shaft 43, and its rotation is performed by manually moving a lever 44 shown in FIG. It is supported by a rod 42.

Several rows of stoppers 45 are arranged on the support plate 40, and by operating a lever to change the rows of stoppers 45 that support the support rod 42, the inclination of the bed board 23 can be changed.

Reference numeral 46 denotes an air mattress, which is fixed to the bed boards 21, 22, and 23.

FIG. 4 shows the state in which the roller 29 is fitted into the guide 28 and the state in which it is attached to the bed board 21. A cam follower is screwed into the bed board 21 as the roller 29.

Next, regarding the operation, when the shaft 24 is driven by the motor 36 via the chino 33 and the connecting plate 32 along the guide 31 in the direction of the rear plate 30, the head of the bed plate 21 is moved by the roller 29 being restrained by the guide 28. and rise.

Therefore, as shown in FIG. 5, the bed board 21 is raised and the patient's body position is raised.

At this time, the bed board 22 is pulled toward the rear board 30 according to the movement of the shaft 24 while being restrained from the floor surface by the rollers 38 of the legs 37.

The inclination of the bed plate 23 is adjusted by operating the lever 44 shown in FIG. 2 and selecting the row of stoppers 45 on the support rod 42.

Since the present invention has the structure and function described above, by restraining the bed board with guides and moving it with a motor, a nurse can easily raise the patient's upper body while the patient is lying down. Can be done.

Unlike the conventional method of fixing the rotation axis of the bed board and raising the bed board around the rotation axis when raising the body, the movement of the bed board is restrained by guides and linear motion is applied to the rotation axis, which reduces the area occupied by the bed board. Since it is small, it is possible to use the space during the day, and at the same time, it is possible to get up at the bedside, which is convenient for handling everyday items that are usually placed at the bedside.

In addition, by folding the part below the knees, it usually becomes an easy chair or a sofa, allowing the sick person to choose a comfortable position, and as above, making effective use of space and effectively using it as a chair when a bed is no longer needed. can be measured.

In addition, the reason why we chose manual operation using electric or pulleys is that this part can be made lightweight, and the legs are also light, so nurses can easily change the angle.

However, when it comes to a chaise longue, it is placed near the bedside, so it does not occupy the middle of the room, and has various other excellent effects.
