Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial Field of Application The present invention relates primarily to improvements in beds for bedridden patients.

BACKGROUND ART Conventionally, there have been beds for patients in which the upper half of the bed body is rotated upward to form a backrest. However, there has never been a bed for a sick person that allows the bed body to be tilted from side to side to easily turn over and change sheets, or to convert the bed into a bathtub so that the patient can take a bath while staying there.

Problems to be Solved by the Invention The present invention not only allows the bed to be converted from a bed for sleeping to a backrest, but also allows the patient to easily turn over by tilting the bed body from side to side. To provide a bed for a sick person that not only can be easily replaced but also allows the sick person to convert the bed into a bathtub and take a bath while staying on the bed body,
The purpose is not only to reduce the fatigue of the sick person, but also to greatly reduce the effort of the caregiver.

Effect: When used normally on a bed, the 17th
When holding the tilting plate 125 in a horizontal state as shown in FIG. 5 by operating the operating lever 129 shown in the figure or the second operating lever 144 shown in FIG. 18,
The rear central panel 101 and the front central panel 102 of the bed main body A are also held horizontally on the tilting plate 125, and the left and right panels 103, 104 are also supported on the lower sides by the left and right frame plates 123, 124, and the rear central panel 101, the front It is held flush and horizontal with the center panel 102 and can be used as a bed as shown in FIG. As a means for further stabilizing the horizontal state, a stopper 135 may be inserted through the front frame plate 121 and into a stopper hole 134 provided in the front frame 109.

When tilting the bed body A to the left or right to turn over or change sheets, tilt the operating lever 129 or the second operating lever 144 to the left, and use the holding device to tilt the bed main body A to the left or right. When this state is maintained, as shown in FIG. 6, the lower part of the operating lever 129 tilts the tilting plate 125 to the left, and therefore both the rear center panel 101 and the front center panel 102 of the bed body A also tilt to the left. However, while the left panel 103 is supported by the left side plate 123, the hinge part 112 is connected to the rear center panel 101.
falls downward, and the left auxiliary panel 105 side rises diagonally upward, preventing the human body from falling. At that time, the locking rod 113 provided on the left auxiliary panel 105 is rotated in the vertical direction, and the left auxiliary panel 1
It will be even safer if 05 is supported and fixed. Hinged portion 112 of right panel 104 with rear center panel 101
rises upward, and its right auxiliary panel 106 side slopes downward, and the right auxiliary panel 106 is connected to the right panel 104.
It hangs down from the hinge part 112.

When tilting to the right, the operation lever 129 or the second operation lever 144 is tilted to the right and held in that state by the holding device, as shown in FIG. can.

In this way, the human body can easily turn over to the left or right, and sheets can be changed easily and quickly.

Next, from the state shown in FIG.
To tilt and stand up the front center panel 10, the handle 157 is rotated to rotate the threaded rod 156, and in communication with the rotation, the connecting rod 153 is activated.
2 is tilted upright as shown in FIGS. 2, 3, and 9, and maintained in that state.

In order to convert it into a bathtub, as mentioned above,
With the front center panel 102 tilted and erected, the bathtub forming panel 150 separately formed on the rear center panel 101 inside the rear frame board 122 is erected and held in that state by a holding device, and then the left and right panels are 103 and 104 are made to stand upward, and the left and right sides of the front central panel 102 are placed on the inner surface of each of them.
The right and left sides of the bathtub forming panel 150 are held between the left and right sides, the left and right panels 103 and 104 are held in an upright state by a holding device, and the sheet 151 is placed from above the front center panel 102, the bathtub forming panel 150, and the left and right panels 103 and 104. , rear center panel 101
A recess is formed in the part to create a bathtub, and when draining water,
The hot water is discharged from the discharge hose 158.

〔Effect of the invention〕

As described above, the present invention allows a sick person to convert the bed from a bed for sleeping to a backrest while remaining on the bed, and further allows the sick person to easily turn over in bed by moving the bed from side to side. I can,
When the front and rear panels of the bed main body A tilt to the left or right due to turning over, the left or right panel on the tilted side, that is, the lower side, automatically stands up diagonally upward with respect to the tilted center panel in the front and back direction. This can prevent the human body from falling from the bed body. In addition, it is possible to provide a bed for a patient that not only makes it easy to change the sheet, but also allows the patient to take a bath by converting the bed into a bathtub, which not only makes it possible to reduce the fatigue of the patient.
This has the effect of greatly reducing the caregiver's assistance efforts.
