The terms first, second, etc. may be used to describe various elements, but the elements should not be limited by terms. It is used only for the purpose of distinguishing from

Inside the first body of the present invention, the lower rail 100 and the motor 1 103 to enable the human body to rotate, the upper rail 500 (not shown), the elastic spring 305 for the purpose of the sit-up exercise, the force of the spring It is possible to provide a motor 2 301, a plurality of elastic bodies 307, a left wire 310 and a right wire 310, and other accessories that can be adjusted.

The wire 205 connected to the traction rings 208a and 208b attached to the lower belt of the present invention is connected to both grooves of the wheel 102 fixed to the shaft of the motor 1 as an outer string to move in both directions. When the motor 1 103 rotates, the wire 205 surrounding one body is wound on the wheel, the wire on the other 205 is released, and the user's body can be rotated in place within the lower rail.

In addition, the upper belt 501, the lower belt 201, and the thigh cover 600 may be worn by the patient for the purpose of the present invention.

Since the gear set 200, the upper belt part, and the thigh cover, which are accessories included in the lower belt part 201 of the present invention, are interconnected, the entire user's body can be rotated only by rotating the lower belt part located at the tailbone part. .

The lower belt part is composed of a plurality of spring air pockets 201 on the inside to protect sensitive skin, and on the outside is composed of a plurality of gear sets to perform left and right linear motion by contact with the lower rail 100. You can make it possible.

In addition, the gear set is in the form of a compatible panel 207, and each panel has a through hole 204-1 having a female screw structure and a through hole 206-1 for fixing the shaft 206, and a screw gear type in each through hole. The tanned bolt and the multipurpose gear 203 can be assembled as a shaft.

The accessories assembled as described above interact with each other to enable the user to rotate the body and also help to prevent unauthorized departure from the bed.

According to an embodiment of the present invention, the lower belt worn by the user and the lower rail may have different motion curved structures, so that the lower belt must be separated from the lower rail during rotation.

For example, when the user rotates the body, the headless bolt 204 of the lower belt gear set contacts the rack gear 105 located on the lower rail. At this time, according to the gears 204-1 inside the through holes of the gear set panel 207, the tanning bolts rotating in both panels simultaneously move into the panel.

As the tanning bolt 204 moves into the panel as above, a portion of the lower belt may be separated from the lower rail. On the contrary, when the body rotation is returned to its original position, the accessory multipurpose gear 203 of the lower belt rotates in contact with the gear 108 of the lower rail. At this time, the tanning bolts protrude outside both panels. The above home position means a state in which the user is looking at the ceiling.

The multi-purpose gear and the tanning bolt are engaged. When the multi-purpose gear contacts the protruding gear 108 of the lower rail and rotates, the tanning bolt also rotates and protrudes out of the panel. At this time, the gear set of the lower belt is constrained to the lower rail.

The above gear set allows the user's lower belt to move freely on the lower rail during the user's body rotation and sit-up exercise, but cannot be completely separated, thus preventing a fall accident unless the user loosens the lower belt. have. When the user loosens the belt, a notification can be set by a signal placed on the belt.

For example, when the motor 103 rotates left according to the program of the control box, the left shaft wire is wound. At this time, the left shaft wire is wound in one groove of the wheel 102, but the right wire wound in the other groove of the wheel is released, so that the patient's body can rotate from its place to the left.

In the above wire movement, one end of the wire is connected to a ring 208a located between the navel and the side of the lower belt, and the wire is connected to a plurality of gear sets, through the grooves 203-4 of the multipurpose gear inside the gear set. It passes through the long hole through-hole (not shown) of the predetermined lower rail and winds several times in the wheel groove 102a located at the lower end of the lower rail. And, in the same direction, the other grooves 102b are also wound several times.

As described above, the wire wound around the groove of the wheel 102b passes through the long hole through-hole provided in the center of the protruding gear 108 of the lower rail and can be connected to the ring 208b via a plurality of gear sets.

The user who wears the lower belt equipped with the wire 205 as described above can rotate the body in place by the motor, whether voluntarily or otherwise.

The upper belt of the present invention may be in the form of a suspender and is connected to both sides of the user in a compatible structure as a lower belt and a curved bar 502 capable of length adjustment. When the lower belt is rotated, the upper body can be safely rotated without distortion.

The motor used in the present invention may be a servo motor. Even when the user is not conscious, it can rotate continuously. When the user can voluntarily rotate, a no-brake type servo motor can be used to reduce the user's feeling of restraining the body.

However, after free physical activity as described above, the user can be placed on the bed after time has elapsed according to the home position program setting of the motor. The above correct position means a state in which the user is looking at the ceiling.

In the present invention, a first elastic body double torsion spring (FIG. 4-305) having a 90 degree angle is installed so that the user can perform the sit-up exercise, so that when the user cannot exercise by magnetic force, the user can do sit-ups with the help of the above elastic body. I can. In addition, it is possible to finely adjust the tensile force of the second elastic body tension spring (Fig. 4-308) with a rotating device including a screw bolt 316 so that the restoring force of the first elastic body can be finely adjusted by the operation of the motor 301.

As above, in order to adjust the force of the sit-up of the first elastic body, the second elastic body 308, the tension spring 308 including the female thread coupling 309, the spur gear 319 and the universal joint 312, the screw gear ( 313), a hanger 311, a screw female thread 314, and the like may be included in the present invention.

For example, as shown in Fig. 4, the force of the first elastic body is 0 kg. To perform the sit-up exercise in the above state, first calculate the user's strength as a low value and manipulate the value in the control box. When the motor 301 is operated, the gears of the motor shaft may rotate the left 302 and the right gear 302-1 adjacent to each other simultaneously using a belt or the like.

The above left and right gears are fixedly connected to the bar 320 including the universal joint and the screw gear, respectively, so that rotation of the above gears simultaneously rotates the screw gear included in the bar 320.

Rotation of the screw gear 313 as described above can push and pull the screw female screw 314. In addition, the screw female screw is fixedly connected to the end 315 of the first elastic body in a hinged manner to push and pull the first elastic body 305.

When pulling with rotation of the screw gear as above, the force that causes the upper body can be raised from 0kg to the specified kg. In addition, when it rotates and reaches the end point of the screw gear, there is no gear shape, so it is idle (see Figs. 4 and 5).

Even in the above state, if the force of the double torsion spring is insufficient, the motor 2 301 may continue to rotate to rotate the screw bolt 316. Accordingly, the second elastic body 308 can be pulled by the female screw 309-1 of the female screw coupling 309 installed at one end of the second elastic body 308. In addition, the other end of the second elastic body is connected with a wire 310 to the ring of the end 305-1 of the first elastic body as shown in Figure 4, so that the force that causes the upper body by rotation of the motor 2 can be adjusted according to the user's momentum. Yes (see Figs. 4 and 5)

As above, when the patient sits with his upper body raised, 70% of the body weight acts as the patient's hip and tailbone, so the most bedsores occur near the patient's tailbone.

In the second body of the present invention, in particular, in order to prevent bedsores near the buttocks and tailbone, the pusher 410 of the third body is a structure capable of linear motion, and compression in order to control the force of the linear motion of the third body It can be composed of a spring 402, a screw bar 403, and the like.

For example, as shown in FIG. 6-2, the air pocket mats 408 and 409 of the third body may be disposed at the same height as the mattress of the bed. When the sit-up exercise is performed in the above state, it is bent by a bar (FIG. 6-407) connected to the lower rail 100 as shown in FIG. 2 and ascends, thereby pulling the third body part.

In addition, the third body is pushed by the restoring force of the compression spring 402 fixedly located on the second body. In addition, a bar 410 serving as a pusher and a baby pusher (410-1, 2, 3) are installed at the upper end of the body of the third body, so that the left and right movement of the pusher can structurally change the spring air pocket mats (409,408) into vertical movement. So, if the user raises the body after wearing the belt, the air pocket mat can naturally support the buttocks.

You can push up the air pocket mat as much as you want by moving the baby pusher as above. In addition, when the patient lies down, the air pocket mat sinks due to the weight of the hip while the third body part pusher 410 moves backward naturally.

However, even when the patient is lying down, the pressing plate 403-1 narrows the gap between the compression spring 402 by screw rotation of the screw bar (FIG. 6-403). Therefore, the force of the compression spring is increased, and if rotated in the opposite direction, the force of the compression spring can be reduced. This allows the force to be adjusted according to the patient's weight and strength. After all, even when the patient is lying down, the air pocket mat can prevent bedsores near the tailbone by lifting the patient's hip upwards only by rotating the adjustment gear 405. In addition, a power device such as a motor may be connected to the spur gear 405 to be used.

A compression spring 702 was installed inside the air pocket 700, and it was separated into upper and lower portions for the apparatus of the compression spring. When combined, it can be assembled by screws installed in the body of each part (see FIG. 11).

Compression springs are installed in the upper and lower air pockets assembled as above, so that the air pocket tries to suck in air with the force of an elastic body through the air inlet 706-1 (not shown) installed under the air pocket. At this time, the air stopper 706 of the lower air pocket may be opened around the hinge.

As described above, when the air introduced into the pocket receives pressure from the top, the air cap of the lower air pocket is closed by the pressure. On the other hand, air may be discharged through the fine hole of the air exhaust port 708 that is always open.

With the above-described device, it can absorb air in an instant and slowly supply air to the user's compressed area, and supply air to the pressure area even at the moment of a change in position that helps prevent bedsores, helping to prevent bedsores. I can.

Among the devices of the present invention may include a thigh cover. The thigh cover 601 is connected to the lower belt 201 and allows the patient to rotate without discomfort between the hip and the thigh during rotational movement of the trunk, and structurally, the cover part is formed in the inner thigh. The hinge at the position of the hip joint of the human body is in the form of a universal joint 602 to minimize discomfort to the user and can lie down or sit down.
