Abstract

PROBLEM TO BE SOLVED: To improve usability in a special nursing home for aged and a general household by turning a bed to the state of a chair and also arbitrarily adjusting the height of the entire bed in a medical bed. SOLUTION: In this chair-functional bed with an elevating and lowering mechanism, after power is fed, by the operation of a hand switch 2, a bottom back part 8 is elevated by the gravity of a motor cylinder 4, elevation is performed by the thrust of the motor cylinder 3 for the elevation and lowering of the entire bed, the height of the bed is adjusted and thus, a bottom leg part 29 is lowered to the position of a right angle by the gravity of the motor cylinder 5.

Description

Detailed Description of the Invention

[Industrial field of application] [0001] In order to make a person with a physical disability more comfortable in bed, the present invention has a chair shape by raising the back and lowering the legs, so that a person can sit down on a chair while eating. You can do it in various postures, and because there is a lifting mechanism,
You can easily get on and off in the low position. At the time of nursing care, the caregiver can work at an arbitrary high position by raising the elevating part, which reduces labor. When I sleep, raise my back a little,
You can rest comfortably by raising the legs a little higher than horizontal.

[Prior Art] There is a bed for a nursing care bed, but there is no bed with an elevating mechanism having a chair function. The legs descend to a position perpendicular to a horizontal position. And, there is no bed with both functions that rises from the horizontal position.

[Problems to be solved by the invention] When using a bed, a person with a physical disability and a user should be able to live in a bed more comfortably, and the work of medical personnel and caregivers should be improved. For the purpose of mitigation.

[Means for Solving the Problems] The structure will be described. 1) Driven by 3 electric motor cylinders (elevator (3)
It is composed of a back part (4) and leg parts (5). 2) The operation is performed with the hand switch (2). 3) The bottom (the back (8), buttocks (28) and legs (29) are connected) and the elevating / lowering frame (10) (15). FIG. FIG. After the power is turned on, the bottom cylinder (8) is raised by operating the hand switch (2), so that the motor cylinder (4) is actuated and the rod (25) attaches the metal fitting (26) attached to the back lifting metal fitting (7). The pulling action
The back lifting bracket (7) rises. Therefore, the bottom back (8) also rises. As the pulley (9) attached to the bottom back (8) rotates, the bottom back (8) slides down, and the bottom buttocks (28) tilt toward the bottom back (8) with the fulcrum (27). The position of the user does not shift forward. The fall is the opposite. When the hand switch (2) is released, it stops at that position. FIG. FIG. By operating the hand switch (2) to lower the bottom leg (29), the motor cylinder (5) is actuated and the leg lifting metal fitting (18) attached to the tip of the rod (19) is pulled, The bottom leg (29) descends with the fulcrum (27) by interlocking the metal fitting (20). FIG. The lowering of the leg lifting bracket (18) to a vertical position also allows the bottom leg (29) to vertically descend. However, in order to descend vertically, it is necessary to raise the upper frame (10) of the bed. Upper frame (1
If 0) is not raised, the sensor will sense it at a certain position and the bottom leg (29) will not be able to descend further. FIG. The bottom leg (29) that has been vertically lowered is raised by operating the hand switch (2). The bottom leg (29) can be raised and raised further from the horizontal position (Fig. 2). When the hand switch (2) is released, it stops at that position.
Descent is the opposite. Figure 6. FIG. When the bed is driven up and down, the upper frame (10) is lifted. Therefore, the motor cylinder (3) is operated by the operation of the hand switch (2), and the rod (21) pushes the metal fitting (22). ) Rises, and the transmission rod (2) connected to the side of the metal fitting (22)
The metal fitting (24) and the arm (16) ascend by pushing 3) interlockingly, and the arms (13) and (14) also ascend as the arms (16) and (17) ascend, so the upper frame (10) ) Rises. Descent is the opposite. When the hand switch (2) is released, it stops at that position.

[Operation] Since this machine has the above-mentioned structure, noise is small, and the height adjustment of the bed, the raising of the back, and the lifting of the legs can be stopped at arbitrary positions, so that the user can comfortably use the apparatus. Therefore, the caregiver can care and care efficiently in a suitable position.

[Embodiment] Since the bed is a chair in the medical bed and the height of the entire bed is not adjustable, it is highly used in nursing homes and general households.

[Advantage of the Invention] The conventional medical bed has only a mechanism for raising and lowering the entire back raising leg or lowering the back raising leg, and according to the present invention, the user does not become bedridden and the bed is placed in a comfortable posture. It enables a comfortable life. Caregiver,
The prevention of back pain and the reduction of labor of nurses are evaluated.

Claims (1)

[Claims] 1. A bed elevating mechanism, a back portion and a leg portion are individually moved up and down, but the back portion is lifted and the leg portion is lowered from a horizontal position. The lowest point descends to a right angle. However, the height of the bed is adjusted by the lifting mechanism before the legs touch the floor. When the legs descend to a right angle, the bed becomes a chair. When the chair is folded, the buttocks are inclined toward the back. 2) The legs also rise above the horizontal position. A chair function bed with a lifting mechanism configured as described above.
