DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wake-up bed apparatus particularly suitable for sick people.

[0002]

2. Description of the Related Art In a bed apparatus for a sick person, a so-called wake-up type bed apparatus which can assist a patient with reduced physical strength to raise his / her upper body when eating may be used. The wake-up type bed device divides a floor plate provided on an upper surface of a bed frame into a plurality of floors in a longitudinal direction of the bed frame, and a floor portion corresponding to an upper body of a user. Can be driven up and down by a drive mechanism.

Therefore, if the floor is driven in the upright direction, a patient who lies on the floor plate via a mattress can raise his / her upper body with little physical strength.

By the way, when the floor is raised and the patient is in the posture in which the upper body is raised, the buttocks easily move forward by leaning on the floor, and it is difficult to maintain the posture in which the upper body is raised. It may be.

In view of the above, of the floor portions of the floor plate body divided into a plurality of portions, two floor portions corresponding to the legs of the patient are formed into a mountain shape in accordance with the rising of the floor portion corresponding to the back portion in the rising direction. It is common practice to push up to flex the legs, thereby preventing the hips from moving forward when the patient is raised.

[0006]

Indeed, if the two floors corresponding to the legs are bent into a mountain shape, it is difficult for the patient to move the buttocks forward, so that the patient can maintain the posture in which the upper body is raised. It will be easier. However, some patients with legs may need to maintain their legs extended without flexing, and for such patients, raise the floor to raise the upper body. However, it is preferable that the floor corresponding to the leg is not bent.

In other words, depending on the condition of the patient, it may be better that the floor for bending the legs does not interlock with the rise of the floor for raising the upper body. A wake-up bed device that can select whether or not to do so will be required.

The present invention has been made based on the above circumstances, and an object of the present invention is to selectively provide a floor for bending a leg in response to a movement of the floor for raising the user's upper body. An object of the present invention is to provide a wake-up type bed device that can be linked.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a wake-up type bed apparatus capable of raising a user's upper body, comprising a bed frame and a central portion in the longitudinal direction of the bed frame. A movable floor portion having one end portion rotatably supported, a leg floor portion disposed on one end side of the movable floor portion, and one longitudinal end portion rotating at the other end portion of the movable floor portion A raised floor portion connected and provided freely, a drive mechanism for raising and lowering the raised floor portion,
Fulcrum switching means for switching a fulcrum of rotation of the back-raising floor when the back-raising floor is rotationally driven by the driving mechanism in a rising direction; and the back-raising by the fulcrum switching means. The fulcrum of the rotation of the floor portion is a first state in which the movable floor portion is fixed to the bed frame so as not to be able to rotate and is a connection end portion with the movable floor portion, and the movable floor portion is rotated. It is possible to switch to a second state in which the position is separated by a predetermined distance from the connection end with the movable floor portion.

[0010]

According to the above construction, if the fulcrum for rotating the back-raising floor in the rising direction is selected in the first state by the fulcrum switching means, only the back-raising floor is rotated. If the user chooses the second state without bending the legs of the person, the movable floor is inclined in conjunction with the movement when the back raising floor is rotated. The user's leg can be bent.

Are supported in a substantially horizontal state by a third support member 21 provided on the upper surface of the first member.

As shown in FIG. 6, each of the floors 7, 9, and 12 has a pair of connecting rods 7a, 9a, and 12a separated in parallel in the width direction of the bed frame 1.
B, 9b, and 12b are connected to each other, and a floor plate 22 indicated by a chain line in FIG. The floor plate 22 is formed of, for example, a synthetic resin.

When the back raising floor 12 is driven up and down by the driving mechanism 16, the back raising floor 12 switches the fulcrum of rotation between the first state and the second state by the fulcrum switching means 23. You can do it.

The first state of the fulcrum switching means 23 is as follows.
The back raising floor portion 12 is raised and lowered with a pivot shaft 12a at one end connected to the movable floor portion 7 as a fulcrum, and as shown in FIG. 1 or FIG. 3 to FIG. 7 are provided on both sides in the width direction of the lower surface of the other end of the first through hole 2.
4 and a second bracket 25 provided on the inner surface of the vertical rod 2 of the bed frame 1 and facing the first through hole 24 when the movable floor 7 is substantially horizontal. A first locking plate 27 having a through hole 26 formed therein;
The first through hole 24 and the second through hole 26 are set by an engaging shaft 28 which is detachably inserted into the through holes in a state where the first through hole 24 and the second through hole 26 face each other.

The second through-hole 26 communicates with the inside of the vertical rod 2, and one end of a first pipe 24a is fitted and fixed to the first through-hole 24. The other end of the first pipe 24a is close to the second through hole 24. Therefore, the locking shaft 28 is guided from the first through hole 24 by the pipe 24a and can be inserted into the second through hole 26.

As shown in FIG. 4, the movable floor portion 7 is set in the first state by passing the locking shaft 28 through the first through-hole 24 and the second through-hole 26 so that the movable floor portion 7 is in the bed frame. 1, the back-raising floor 12 can be rotated about the pivot 12 a, which is a connection end with the movable floor 7, as a fulcrum.

The second state of the fulcrum switching means 23 is as follows.
The back raising floor 12 is raised and lowered around a position different from the pivot 12a as a fulcrum, and the first raising floor 12 is provided at one end of the back raising floor 12 as shown in FIGS.
A third through hole 31 formed in the bracket 13 and a third through hole 31 provided on the inner surface of the vertical rod 2 of the bed frame 1 when the raised floor portion 12 is substantially horizontal.
A second locking plate 33 having a fourth through-hole 32 formed opposite thereto and the locking shaft 28 removably passed through the third and fourth through-holes 31 and 32 facing each other. And can be set by.

The fourth through hole 32 communicates with the inside of the vertical rod 2, and one end of a second pipe 31a is fitted and fixed to the third through hole 31. The other end of the second pipe 32a is close to the fourth through hole 32. Therefore, the locking shaft 28 can be inserted into the fourth through hole 32 from the third through hole 31 via the second pipe 31a.

That is, the first state and the second state can be selectively set by the locking shaft 28. When the drive mechanism 16 is operated by selecting the second state through the stop shaft 28 and the drive mechanism 16 is operated, the back-raised floor portion 12 is raised and lowered around the lock shaft 28 as a fulcrum as shown in FIGS. 5 and 7B. Move.

In this case, the pivot point is located at a predetermined distance from the pivot shaft 12a, which is the pivot end with the movable floor 7, so that when the back raising floor 12 is raised, the pivot shaft 12a Thus, one end of the back-raising floor 12 pivotally attached to the movable floor 7 rotates in a downward direction indicated by an arrow X in FIG. As a result, the movable floor 7 has one end supported by the first support member 8 as a fulcrum and the other end connected to the back-raised floor 12.
As a result, it turns in the downward direction indicated by arrow Y and tilts.

If the movable floor 7 is inclined, the movable floor 7
The leg floor 9 pivotally attached to one end of the movable floor 7 rotates and inclines in the opposite direction to the movable floor 7 with the other end supported by the second support member 11 as a fulcrum. Therefore, since the movable floor 7 and the leg floor 9 are substantially in the shape of a letter as shown in FIG. 7B, the user who is lying on the floor plate 22 can raise his / her upper body by the back raising floor 12. When raised, the leg is bent by the movable floor 7 and the leg floor 9.

In the wake-up type bed apparatus constructed as described above, when the user raises his / her upper body, he / she does not want to bend his / her legs due to injury or the like.
There is a case where it is desired to easily maintain the posture in which the upper body is raised by bending.

In the former case, the fulcrum switching means 23 is set to the first state as shown in FIG. That is, the first through-hole 24 of the third bracket 25 and the first locking plate 2 facing each other in a state where the back raising floor portion 12 is horizontally lying down.
7, the movable shaft 7 is inserted into the second through hole 26 to fix the movable floor 7 to the bed frame 1 in a substantially horizontal state so as not to rotate.

In this state, when the drive mechanism 16 is operated to drive the operating shaft 17 in a direction to protrude from the cylinder 19,
The floor 15 is rotated in conjunction with the rotation, and the floor 12 is rotated in the ascending direction about the pivot 12a.

Therefore, the user on the floor plate 22 is raised by the back-raised floor portion 12.
At this time, since the movable floor portion 7 is fixed to the bed frame 1 and does not rotate, the movable floor portion 7 and the leg floor portion 9 are bent upward in a mountain shape, and the user's leg portion is bent. Is not bent.

If the user wants to bend the legs when raising the back, the third bracket 13 of the first bracket 13
And the fourth through hole 3 of the second locking plate 33.
2 and the locking shaft 28 is inserted therethrough,
The fulcrum switching means 23 is changed from the first state to the second state.

When the driving source 18 of the driving mechanism 16 is operated to drive the operating shaft 17 in the protruding direction, the back-raising floor portion 12 is pivotally moved up with the locking shaft 28 as a fulcrum to lift the upper body of the user. Will wake up.

At this time, since the fulcrum of the rotation of the back-raising floor 12 is located at a position away from the pivotally connected end with the movable floor 7,
One end of the back-raised floor portion 12 rotates downward as indicated by an arrow X in FIG. 5, and the movable floor portion 7 is rotatable about one end supported by the first support member 8 as a fulcrum. , The other end rotates in the downward direction indicated by the arrow Y.

When the movable floor 7 rotates, the rotation of the movable floor 7 is linked with the leg floor 9 having one end pivotally connected thereto.
The leg floor 9 is bent in a mountain shape to support the user's leg in a bent state. Therefore, the user who has raised the upper body can easily maintain the posture in which the upper body is raised because the buttocks are hardly shifted forward by bending the legs. Moreover, at this time, since the movable floor 7 lowers and tilts the other end where the user's hips are located, it is also possible to restrict the hips from moving forward.

As described above, when the user raises his / her upper body, the fulcrum switching means 23 causes the movable floor 7 and the leg floor 9 to move.
This is very convenient because one of a first state in which the user does not bend and a second state in which the user can bend into a mountain shape can be selected according to the state or preference of the user's leg. .

The present invention is not limited to the above embodiment, and can be variously modified without departing from the gist of the invention. For example, in the above-described embodiment, the leg floor is rotatably provided so as to interlock with the rotation of the movable floor. However, only the movable floor is provided so as to be rotatable, and the leg floor is substantially attached to the bed frame. It may be provided fixed in a horizontal state. In this case, even if the leg floor is substantially horizontal, the other end of the movable floor descends and inclines, so that the leg of the user is bent to make it difficult for the buttocks to move forward. Can be.

[0038]

As described above, according to the present invention, the rotating fulcrum of the raised floor portion driven up and down by the drive mechanism is fixed to the bed frame by the fulcrum switching means so that the movable floor portion cannot be rotated. The first end to be connected to the movable floor
And a second state in which the movable floor is rotatable and is located at a predetermined distance from the connection end with the movable floor.

Therefore, if the first state is set, the user can raise the upper body without bending the legs by holding the movable floor in a substantially horizontal state and raising the back-raising floor. Can be. Also, if you set it to the second state,
When the back-raised floor is raised, the movable floor can be inclined so that the end located on the back-raised floor is lowered, so that the upper body can be raised and the legs can be bent at the same time. .

That is, since the first state and the second state can be selected, these states can be used properly according to the state of the legs and the physical condition of the user, which is very convenient. is there.
