It is about a bed equipped with.

[0002]

2. Description of the Related Art Conventionally, in a bed provided with a floor undulating mechanism, a bottom is divided into, for example, a back bottom, a waist bottom, a leg bottom, etc., and a structure in which they are flexibly connected by a hinge is used. Many.

[0003]

[Problems to be Solved by the Invention] However, when raising the back, the back bottom bends around the hinge, which is a connection point with the waist bottom, and wakes up. When a force is exerted on the patient's body toward the leg side, and as a result of repeated rising, the patient's body shifts toward the leg side. The present invention has been proposed in order to improve such inconvenience, and when raising the back, by moving the back bottom to the headboard side,
An object of the present invention is to provide a bed provided with a floor undulating mechanism that prevents the phenomenon that the body of a patient shifts to the leg side.

[0004]

In order to solve the above-mentioned problems, the present invention relates to a bed having a floor undulating mechanism, in which the bottom is divided into a back bottom, a waist bottom, a knee bottom, and a leg bottom, and is bent. The back bottom is divided into a first back bottom corresponding to the patient's back and a second back bottom close to the waist, and the second back bottom
The length of the bed in the longitudinal direction of the bed is smaller than that of the first back bottom, and the support frame is attached to the back surface of the first back bottom, and the end of this support frame can be slid diagonally upward and headboard side. And one end of the second back bottom is flexibly attached to the support frame, and the other end of the second back bottom is flexibly connected to the waist bottom corresponding to the waist of the patient, and the back raising mechanism is connected to the support frame. Are connected. Further, in the above-described configuration, a support frame is provided on the back surface of the second back bottom, and one end of the support frame is flexibly connected to the support frame at the first back bottom, while the other end of the support frame is projected to the waist bottom side. The support frame extending toward the waist bottom and the second back bottom is provided on the back of the knee bottom, and the second frame is provided.
The other end of the support frame on the back of the back bottom and the support frame on the back of the knee bottom may be connected to each other so that the knee bottom is interlocked with the ups and downs of the second back bottom.

[0005]

[Function] When the floor undulation mechanism is activated, the back bottom will move to the first position.
The user bends and wakes up by setting the connecting portion between the back bottom support frame end portion and the bottom receiver in the bed frame and the connecting portion between the second back bottom and the waist bottom as the bending portion. At this time, the first back bottom moves diagonally upward to the headboard side along the elongated hole provided in the bottom receiver at the end of the supporting frame, and
The back bottom bends with respect to the support frame. As the support frame moves diagonally upward to the headboard side, the first back bottom wakes up in such a manner as to shift to the headboard side.
As a result, the patient does not receive the force of being pushed out to the leg side from the back bottom, and does not shift to the leg side even if the user gets up several times. Further, if the knee bottom is linked to the undulation of the second back bottom, the configuration of the floor undulation mechanism can be further simplified.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a bed equipped with a floor undulating mechanism according to the present invention will be described below with reference to the accompanying drawings with reference to an embodiment. A bed 1 is shown in FIG. 1, and this bed 1 is configured by dividing a bottom 3 supported on a frame 2 into a back bottom 4, a waist bottom 5, a knee bottom 6, and a leg bottom 7 and sequentially connecting them flexibly. It is a thing. The back bottom 4 is divided into a first back bottom 4a corresponding to the back of the patient and a second back bottom 4b close to the waist. That is, in the back bottom 4, the first back bottom 4a
As shown in FIG. 2, three bottom units having a width of 190 mm are attached to the support frame 8, and the second back bottom 4b can be formed by one bottom unit having a width of 190 mm. The second back bottom 4b is flexibly attached to the support frame 8 of the first back bottom 4a via one end of a support frame 9 provided on the back surface, and at the same time, the second back bottom 4b.
The other end of the b support frame 9 is flexibly connected to the waist bottom 5. The waist bottom 5 is fixedly supported by the frame 2 via a waist bottom receiver 10. And such waist bottom receiver 10
Is provided with a back bottom receiver 11 for supporting the support frame 8 of the first back bottom 4a. That is, the end portion of the support frame 8 of the first back bottom 4a passes through the back bottom receiver 11,
An elongated hole 12 formed in the back bottom receiver 11 is movably attached. The elongated hole 12 is formed so as to be directed obliquely upward and toward the headboard 13 side. Further, a back raising arm 15 which constitutes a back raising mechanism 14 is attached to the support frame 8. The back-raising mechanism 14 includes a motor 16, a drive shaft 17 that moves forward and backward when the motor 16 is activated, and the back-raising arm 15. Although the bed 1 having such a structure has a knee raising mechanism in addition to this, illustration and description thereof are omitted here.

In the bed 1 having the above-mentioned structure, when the back raising mechanism 14 is activated, the back bottom 4 is connected to the second back bottom 4b and the waist bottom 5, the end of the support frame 8 and the back of the frame 2. Awakening is performed by using a connecting portion with the bottom receiver 11 as a bent portion. Initially, the second back bottom 4b and the first back bottom 4a are integrally bent, but when raised to some extent, the end of the support frame 8 causes the back bottom receiver 11 to be slanted toward the headboard 13 side along the slot 12. While moving upward, the second back bottom 4b bends with respect to the support frame 8. As the support frame 8 moves diagonally upward to the headboard 13 side, the first back bottom 4a wakes up in such a manner as to shift to the headboard 13 side (see FIGS. 3 and 4). As a result, the patient does not receive the force of being pushed out from the back bottom 4 to the leg side, and does not shift to the leg side even after repeatedly getting up several times.

Next, the bed provided with the floor undulating mechanism according to the present invention can also be implemented by the structure as shown in FIGS. In the present embodiment, constituent elements that are substantially the same as the constituent elements of the bed 1 in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted. That is, in the bed 20 in the present embodiment, the support frame 21 is provided on the rear surface of the divided second back bottom 4b, and one end of the support frame 21 is displaceably connected to the support frame 8 in the first back bottom 4a. On the other hand, the knee bottom 6
A support frame 22 extending toward the waist bottom 5 and the second back bottom 4b is provided on the back surface, and the support frame 21 on the back surface of the second back bottom 4b and the support frame 22 on the back surface of the knee bottom 6 are provided.
And are connected so as to be interlocked with each other through an elongated hole 23 provided in the support frame 22. And the first back bottom 4a
The back-raising link 24 that constitutes the back-raising mechanism 14 is in contact with the support frame 8 via the roller 25.

In the bed 20, when the back raising mechanism 14 is activated, the back raising link 24 is displaced and the support frame 8 on the first back bottom 4a is raised, and the end of the support frame 8 is placed on the back bottom receiver 11. It moves diagonally upward toward the headboard 13 side along the slot 12. As the support frame 8 is raised, the support frame 21 of the second back bottom 4b is displaced in the clockwise direction together with the second back bottom 4b. Initially, the end portion of the support frame 21 of the second back bottom 4b is moved in the support frame 22 while floating in the long hole 23 in the support frame 22 on the back surface of the knee bottom 6.
While interlocking with each other, the support frame 22 is interlocked and displaced so as to reach the end of the long hole 23 and pull the support frame 22 toward the headboard 13 side. Then, the knee bottom 6 wakes up using the connection point with the waist bottom 5 as a bending point, lifts the connection point with the leg bottom 7, and the knee raising is completed (see FIG. 7). As described above, also in this embodiment, the first back bottom 4a is raised by raising the back.
Moves diagonally upward to the headboard 13 side, so that the patient does not receive a force from the back bottom 4 to the leg side, and does not shift to the leg side even if the user wakes up several times. In addition, in this embodiment, since the back raising mechanism 14 is activated, the knees can be raised in addition to the back raising.
There is no need for a drive system exclusively for raising the knees, and it is possible to reduce the complexity of the structure and the cost.

[0010]

As described above, according to the present invention, the back of the patient is not pushed out by the back bottom even when the undulation is repeated, and the body of the patient shifts to the leg side. Can be prevented, resulting in a comfortable bed life.
