Abstract

PROBLEM TO BE SOLVED: To prevent a patient from being subjected to bending pressure on the abdomen part and pressed at the chest part and the diaphragm by pushing up of a bed face, by sliding a hinge on a bed face by the thickness of a mat and elevating the bed face using a compression spring as assisting power. SOLUTION: When a roller 5 moves, a link 1 is pushed to rotate a link 2 around a fixed shaft 6 since a roller shaft 8 cannot vertically move but can laterally slide. The link has different lengths from the fixed shaft 6 to both ends and a link 4 connected with a link 2 via s link shaft 11 is rotated around a fixed shaft 7 when the link rotates. The link has different lengths from the fixed shaft to both ends and the link shaft 12 rotates by the mat thickness to move the hinge point on the bed face. When the link 2 slides up on the back rest of the chair then pushes up a bed board, the bed board pulls another bed board down.

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a mechanism for improving a mechanical sleeper (gage bed) for home care. [0002] A conventional home care nursing gadget bed uses a floor hinge (hinge, hinge) to provide a back part (a home care mechanical bed). The back part) and the lower part of the buttocks (thighs) and the lower part of the feet (lower thighs) are bent manually or electrically, causing the person who is lying supine (sleeping) to eat, She was in a sitting position (positioning) watching TV. The floor lifting device uses a motor and an actuator that uses screws and nuts, and pushes up the entire floor with a seesaw structure. In this case, since the circular motion is performed around the two fulcrums, the floor surface is displaced from the wall surface of the room at low and high positions, which is inconvenient and dangerous. [0003] In the case of a person or an elderly person (hereinafter referred to as a patient) having a low trunk holding force, the muscle strength is weak, and therefore, the back of the floor is supported by an actuator using the floor hinge as a fulcrum. When pushed up, the hinge point should be directly below the joint of the lumbar part of the body, but because of the thickness of the mat on the bed, it is displaced downward, so follow the pushing up of the floor surface, Bending pressure was applied to the abdomen. Also the chest,
The patient was distressed by compressing to the diaphragm. A healthy person moves his waist and back back and forth to make adjustments, but the patient cannot. Until now, the seesaw type floor lifting device could be lifted and lowered with a small driving force using a lever, but if this is made into a leg-shaped opening and closing structure by halving the pantograph, when the legs are opened from a low position Needed great power. The reason for changing from the seesaw structure type to the leg type type is that there is a risk of scissors at the intersection between the link and the frame. [0004] The present invention has solved the following means as to whether the positioning of a patient cannot be easily performed or the risk cannot be reduced. (B) When pushing up the back of the floor with the actuator,
A method has been devised in which the fulcrum of the hinge is simultaneously slid by the length of the mat so that the patient does not compress by sliding.
The objective was achieved by changing the length of both ends of the fulcrum of the link and using a double structure because the space is narrow because the stroke of the thickness of the mat is shortened by using the lifting stroke of the actuator. FIG. 1 is an explanatory view showing that when the motor is rotated and the nut is moved, the roller 5 moves while rotating to move the link. When the roller 5 moves, the link 1 is pushed, and the roller shaft 8 cannot be moved up and down but can slide in the horizontal direction, and the link 2 is rotated about the fixed shaft 1. The lengths of both ends of the two links 2 are changed around the six fixed shafts 1.
When the second link 2 rotates, the fourth link 4 connected by the third link 3 rotates about the fixed shaft 2. The length of both ends of the link 4 is changed around the fixed shaft 2. The twelve link shafts 3 rotate by the length of the mat thickness to move the hinge points on the floor. FIG. 2 shows the point at which the roller 5 is pushed full stroke and the twelve link shafts 3 are rotated by the thickness of the mat. (B) In FIG. 3, the back portion of the floor is further divided into two portions, and the tip portion is kept horizontal so that the pillow does not fall when the player is in a sitting position. In this case, the divided floor is pushed by 14 lots, but the point of the hinge slides, so that the 13 slot lot link slides the slot-like elongated hole passing through the lot. (C) FIG. 4 shows a state in which the floor plate 2 (back) having the link 23 is pushed up after sliding in the shape of a chair back. At this time, the 23 floor boards 2 pull the 22 floor boards 1 (thighs) down. The 22 floor boards 1 (thigh) are the thigh length of the patient. (D) The right nut 19 and the left nut 20 in FIG.
The left and right screws 17 and 17 rotate to move toward and away from the center of the bed. 15 left screws and 17
Are connected by a central 16 coupling.
This coupling is made universal so as to eliminate the deviation of the shaft center. The right nut of 19 and the left nut of 20 have 18
And holds 21 compression springs between the nuts. As the two nuts approach, the spring is compressed and the floor descends. When raising the floor, two screws are rotated in a direction to separate the two nuts. At this time, the compression spring 21 exerts a force to open and serves as auxiliary power. This assistance is strong when the floor that needs the most power rises with the legs open from the lowest position, and weakens as both nuts move away. FIG. 5 is a cross-sectional view in which the floor is leveled and raised. FIG. 6 is a sectional view in which the floor is lowered. FIG. 7 is a sectional view in which the back of the floor is pushed up. [0005] In this manner, the patient has been bending the spine with the unnatural positioning that has slipped, and has been sitting on the sacrum (sloppy sitting) and watching television. When I was in a sitting position, my pressure on the abdomen and lumbar spine disappeared, and she did not slip off. In addition, the compression-spring open leg type lifting device can be pushed open with a spring to reduce the load from above even if an arm etc. is sandwiched,
The links also reduced the danger as they were held by rollers at both ends and slid away.
