Description

[Detailed Description of the Invention] This invention relates to a bed device that can be used by elderly people, sick people, etc. for various purposes.

For example, for people who cannot move their bodies as they wish, such as the sick or elderly,
There is a need for a bed device that allows an attendant to easily perform tasks such as urinating and changing diapers while lying supine. Furthermore, when such people eat meals, etc., it is difficult for them to maintain an upright posture on their own, so a bed device with a function that allows them to maintain such a posture is required. .

2. Description of the Related Art Conventionally, a bed disclosed in Japanese Utility Model Publication No. 45912/1983 has been known for making it easier for a sick person to perform tasks such as urinating and changing diapers. This bed is provided with the rear end of a movable floor plate pivoted at a position rearward from the center of the bed frame, a pinerest press frame is slidably provided inside the rear part of the bed frame, and the movable floor plate is tilted by a drive mechanism. When the pine tress is pressed, the rear end of the pine tress can be moved forward by the pine tress press frame. A toilet bowl can be inserted into the recess formed on the sloping movable floorboard to relieve the user, and an attendant can insert his or her hand into the recess to change a diaper.

By the way, according to the bed having such a structure, the bed frame is provided with one pinerest of approximately the same size as the bed frame. Therefore, when the movable floorboard is tilted, the pinerest must be bent in accordance with the tilt. Therefore, a push frame that slides in conjunction with the rotation of the movable floor plate is required. Therefore, it is necessary to provide the press frame in a slidable manner and to provide a drive mechanism for sliding it in conjunction with the rotation of the movable floor plate, resulting in a disadvantage that the structure becomes complicated. In addition, the depression created by the bending of the pinerest is open only at both ends of the movable floorboard in the width direction, and the free end of this floorboard is closed, so it is difficult to insert a toilet bowl or change a diaper. In some cases, the working direction was restricted, resulting in poor workability.

Furthermore, the above-mentioned bed does not have a function that allows a sick person, an elderly person, etc. to easily take an upright position with their upper body. Therefore, it is very inconvenient for sick or elderly people who need to sit upright to eat, for example.

This idea was developed based on the above circumstances, and its purpose was to have a simple structure, to be able to do tasks such as inserting a toilet bowl or changing diapers without being restricted, and to be able to do tasks such as eating, etc. To provide a bed device that allows one to easily take a posture with the upper body raised.

An embodiment of this invention will be described below with reference to the drawings. The bed device shown in FIGS. 1 and 2 includes a base body 1. The bed device shown in FIGS. This base body 1 is formed from a pair of side plates 2 that are spaced apart from each other in parallel and face each other, and end members 3 that are respectively connected to both ends of the side plates 2 in the longitudinal direction. A first floor plate 4 and a second floor plate 5, which are formed into a rectangular frame shape and made of pipe material, are arranged on the base body 1 along the longitudinal direction of the base body 1. First connectors 6 are provided on both sides of one end of the first floor plate 4 located on the longitudinal center side of the base body 1 . Further, a first horizontal rod 7 is installed between the side plates 2 at a location corresponding to one end of the first floor plate 4 of the base body 1 . L-shaped first supports 8 are fixed to the upper surfaces of both longitudinal ends of the first horizontal rod 7, and the first connectors 6 are attached to the support shafts 9. It is pivoted by. Further, a receiving crosspiece 9a is installed between the side plates 2 at a location corresponding to the other end of the first floor plate 4 of the base body 1. The other end of the first floor plate 4 is prevented from rotating downward by the receiving bar 9a. In other words, the first floor plate 4 is rotatable only in the upward direction from a horizontal state. Furthermore, a first connecting shaft 10 extending along the width direction of the base body 1 is installed on one end side of the first floor plate 4 .

The second floorboard 5 is provided with second connectors 11 on both inner surfaces of the middle part in the longitudinal direction.
Side plate 2 of base body 1 corresponding to this second connector 11
A second horizontal rod 12 is installed between them. L-shaped second supports 13 are fixed to the upper surfaces of both longitudinal ends of the second horizontal rod 12, and the second connector 11 is attached to the support shaft 1.
It is pivoted by 4. In addition, the second floor plate 5
On both sides of one end located on the first floor plate 4 side,
A connecting piece 15 is fixed to each. Connecting piece 1
As shown in FIG. 5, one end of a link 17 whose intermediate portions are fixed to both ends of a second connecting shaft 16 is pivotally connected to the link 5 by a support shaft 18. A roller 19 is rotatably provided on the outer surface of the other end of the link 17. This roller 19 is rotatably engaged with a rail member 20 having a U-shaped cross section and attached to the lower surface of the side plate 2. When the link 17 is in the vertical position, the second floor plate 5 is held horizontally. Then, when the roller 19 rolls on the rail member 20 and the link 17 falls down as shown in FIG. 3, the second floor plate 5 rotates in a direction in which one end side located on the first floor plate 4 side becomes lower. do.

Furthermore, nets 21 are stretched over the first and second floorboards 4 and 5, and a first mattress 22 and a second mattress 23 are placed on each net 21, respectively. Furthermore, the first and second floor plates 4 and 5
A presser plate 24 having an L-shaped cross section is fixed to both longitudinal ends of the base 1, and when the first and second floor plates 4, 5 are tilted by the presser plate 24, the first and second floor plates 4, 5 are tilted. The second pinerests 22, 23 are prevented from shifting.

The first floor plate 4 and the second floor plate 5 are driven by a first drive mechanism 25 and a second drive mechanism 26, respectively. That is, each of the drive mechanisms 25 and 26 has a drive part 27 in which a nut (not shown) is rotatably provided, and the nut can be rotated by a handle 28 provided at one end of the drive part 27. One end of each drive section 27 is pivotally attached to the cover body 29. This cover body 2
9 is fixed to a pair of mounting rods 30 installed at one end of the base 1 on the second floor plate 5 side. A male thread (not shown) formed at one end of the drive shaft 31 is screwed into the nut of each drive portion 27 . Therefore, when the nut is rotated by the handle 28, the drive shaft 31 moves forward and backward in its axial direction. The other end of the drive shaft 31 of the first drive mechanism 25 is pivotally connected by a support shaft 33 to the other end of a first arm 32, one end of which is fixed to the middle of the first connection shaft 10. The other end of the drive shaft 31 of the second drive mechanism 26 is pivotally connected to the other end of a second arm 34, one end of which is fixed to the middle of the second connection shaft 16, by a support shaft 35. There is. Therefore, the first drive mechanism 25
When the drive shaft 31 is driven in the direction of protruding from the drive portion 27, the first arm 32 rotates in the direction shown by the arrow in FIG. 2, and the first floor plate 4 rotates upward. Further, when the drive shaft 31 of the second drive mechanism 26 is moved backward toward the drive section 27, the link 17 together with the second arm 34 rotates in the direction shown by the arrow in FIG. 2, as shown in FIG. Since the second floor plate 5 falls down, the second floor plate 5 is designed to rotate in such a direction that this one end side becomes lower.

In the bed device configured as described above, when the user M, such as an elderly person or a sick person, is to relieve himself or change a diaper while lying on his back, as shown in FIG. The mechanism 26 is operated to rotate the second floorboard 5 in a direction in which one end of the second floorboard 5 on the first floorboard 4 side becomes lower. Then, a space S is created between the buttocks of the user M and the upper surface of the second mattress 23 provided on the second floorboard 5. Therefore, a toilet bowl can be inserted into this space S to relieve the user, or a diaper can be changed using this space S. The space S is not only open in the width direction of the second floorboard 5, but also
Since the end on the side of the first floor plate 4 is open, the direction of insertion and removal of the toilet bowl into the space S, the direction of operation when changing diapers, etc. are not limited only to the width direction. In other words, since the first pinerest 22 provided on the first floorboard 4 and the second pinerest 23 provided on the second floorboard 5 are separate bodies, when the second floorboard 5 is tilted, The end of the resulting space S on the first floor plate 4 side is not blocked. Moreover, in response to the rotation of the second floorboard 5, the first and second pinerests 22, 23 are moved between the floorboards 4, 5.
There's no need to slide it up.

On the other hand, when user M raises his upper body to eat or read on the bed device, he operates the first drive mechanism 25 to move the first floor plate 4 as shown by the chain line in FIG. Increase rotation. If the user M leans on the first pine rest 22 provided on the first floorboard 4, the user M can easily maintain an upright posture with the upper body.

Note that in the above embodiment, the first and second drive mechanisms 2
5 and 26 are driven by the handle 28, they may be driven by a motor instead of the handle 28.

As described above, this invention includes a base, a first floor plate rotatably supported at one end located at the center in the longitudinal direction of the base, and a second floor plate rotatably supported at a midway portion. A first pine mattress is placed on the first floor plate, and a second pine tree is placed on the second floor plate.
The first floor plate can be rotated by the first drive mechanism, and the second floor plate is rotated by the second drive mechanism with the middle part as a fulcrum. One end located on the floorboard side of the can be rotated in the downward direction. Therefore, if the second floor plate is rotated so that one end on the first floor plate side is lowered, a space will be created between one end of the second floor plate and one end of the first floor plate. Because of this, this space can be used to allow users who are lying on their backs, such as elderly or sick people, to relieve themselves or change diapers. Since the first pine tress and the second pine tress are separate, the space is open along three directions at one end of the second floorboard, so that the user can use the space to use the toilet. , the direction in which tasks such as changing diapers can be performed is not so restricted, and work efficiency can be improved. Further, when rotating the second floor plate to form a space, there is no need to slide the pinerest on the floor plate as in the conventional case, so the structure can be simplified. Furthermore, if the first floor plate is rotated and raised, the user can lean on it, so that the user can easily maintain an upright posture when eating, reading, or the like. Also, one end side of the link is pivotally connected to a connecting piece provided on both sides of one end of the second floor plate, and a roller rotatably provided on the other end side of the link is engaged with a rail member provided on the base. one end of the arm is connected to a connecting shaft that connects the links, and a drive shaft that is driven forward and backward in the axial direction by a drive section is pivotally connected to the other end of the arm. So, the second
Not only can the second floor plate be driven reliably and smoothly, but also the second floor plate can be reliably supported not only horizontally but also when tilted at a predetermined angle without shaking. It may be easier to provide assistance.
