Abstract

PURPOSE:To allow a patient to sit on a bed without any need of leaning his/her body even at the time of rising by dividing a floor section into four portions. CONSTITUTION:A bottom 3 is divided into a back bottom 3a, a waist bottom 3b, a knee bottom 3c and a leg bottom 3d. The bottom 3b is horizontally fixed to and supported on a frame 2 via a pillar 6, and the support frame 4a of the bottom 3a is rotatably jointed to the support frame 4b of the bottom 3b. The support frame 4c of the bottom 3c is jointed to the frame 4b via a slit 7 and the intermediate section of the frame 4c is rotatably jointed to the support frame 4b of the bottom 3b. As a result, a patient can sit without leaning his/her body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, in a bed having a floor undulating mechanism, divides the floor into four parts so that the patient can sit down without tilting his / her body even when getting up. The present invention relates to a bottom structure of a bed including a floor undulating mechanism.

[0002]

2. Description of the Related Art Most of recent beds have a floor undulating mechanism. For example, as shown in FIG. 3, the bottom of the bed A is divided into a back bottom B, a waist bottom C and a leg bottom D. By activating the floor undulation mechanism, you can raise your back and legs. In such a bed A, raising the back and raising the legs, raising the patient, sitting on the bottom side edges, putting feet on the floor, transferring to a wheelchair, or standing up is performed. ing. In addition, the erection mechanism for raising the back and raising the legs have been provided separately for raising the back and raising the legs.

[0003]

However, when raising the back and raising the legs, the waist bottom C at the position where the patient sits is inclined toward the back bottom B side, which makes it very difficult to sit. This will hinder the transition from a sitting state to rehabilitation such as start-up training and transfer to a wheelchair or the like. Since the hoisting mechanism for raising the back and the raising mechanism for raising the leg are respectively provided, the structure is complicated and the weight is increased. Therefore, the applicant divides the bottom into four parts, a back bottom E, a waist bottom F, a knee bottom G, and a leg bottom H, as shown in FIG. 4, and fixes the waist bottom F on which the patient sits in a horizontal state. If so, the patient's body can be stabilized, and the sitting posture can be easily maintained at the bottom end. If the back bottom E and the knee bottom G are configured to interlock with each other, the back raising mechanism can be used to raise the back. , Came to the perspective that leg lifts could be achieved. The present invention has been proposed from the above viewpoints, and in a bed provided with a floor undulating mechanism, when the floor is divided into four and wakes up, the patient can sit and the mechanism is combined. An object is to provide a bed bottom structure having a simplified floor undulation mechanism.

[0004]

In order to solve the above-mentioned problems, according to the present invention, in a bed provided with a floor undulating mechanism, the bottom is divided into a back bottom, a waist bottom, a knee bottom and a leg bottom. A support frame is provided on the back surface of the bottom, and the back bottom, waist bottom, and knee bottom are connected by a support frame that supports these bottoms. The waist bottom is fixedly supported by the bed frame, and the support frame of the back bottom is supported by the waist bottom. A structure in which the support frame of the knee bottom is connected to the support frame of the knee bottom through an elongated hole, and the support frame of the knee bottom is pivotally connected to the support frame of the waist bottom at an intermediate portion. age,
The back raising mechanism is connected to the support frame at the back bottom.

[0005]

When the back raising mechanism is activated to raise the back and knees, the support frame of the back bottom is raised and the back bottom can be raised. When the support frame of the back bottom rises, the tip of the support frame of the back bottom moves to the end of the slot while moving the support frame of the knee bottom while moving in the slot of the support frame of the knee bottom. The support frame of the knee bottom is displaced around the connection point with the support frame of the waist bottom. As a result, the knee bottom is inclined, and the knee bottom is raised together with the leg bottom to complete the knee raising. Therefore, raising the back and knees only with the back raising mechanism
It is possible. By the way, the waist bottom is not affected by the ups and downs of the back bottom, knee bottom and leg bottom,
Maintaining a horizontal position, the patient can sit in the waist bottom position without leaning.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a bottom structure of a bed provided 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. 1 and 2 show a bed 1 having a floor undulating mechanism. In this bed 1, the bottom 3 on the frame 2 is the back bottom 3a, the waist bottom 3b,
Support frames 4a, 4b, 4c, 4d are provided on the back surfaces of the bottoms 3 by dividing them into knee bottoms 3c and leg bottoms 3d. They are connected via 4b and 4c. Further, the knee bottom 3c and the leg bottom 3d connect the support frame 4c and the support frame 4d by a hinge 5. The waist bottom 3b is fixedly supported by the frame 2 in a horizontal state via a support column 6, the support frame 4a of the back bottom 3a is rotatably connected to the support frame 4b of the waist bottom 3b, and the knee bottom 3c is supported. The support frame 4c is connected through the elongated hole 7, and the support frame 4c of the knee bottom 3c is rotatably connected to the support frame 4b of the waist bottom 3b at an intermediate portion,
A back raising link (not shown) constituting a back raising mechanism is connected to the support frame 4a of the back bottom 3a.

In the bed 1 having the floor undulating mechanism having the bottom 3 having the above-described structure, when the back raising mechanism is activated to raise the back and knees, the support frame 4a of the back bottom 3a is activated by the back raising link. Is raised and the back bottom 3a
Can be woken up. Support frame 4a for the back bottom 3a
Is displaced around the joint between the waist bottom 3b and the support frame 4b, and the tip end of the support frame 4a floats in the long hole 7 of the support frame 4c of the knee bottom 3c while the support frame 4 of the knee bottom 3c is supported.
While moving c, it reaches the end of the long hole 7, and the support frame 4c of the knee bottom 3c is displaced around the connection point with the support frame 4b of the waist bottom 3b. This tilts the knee bottom 3c,
Along with the leg bottom 3d, the knee is lifted up and completed (see FIG. 1).
reference). Therefore, since only the back-raising mechanism can raise the back and the knees, a hoisting mechanism is unnecessary in addition to the back-raising mechanism. By the way, the waist bottom 3b is fixedly supported by the frame 2 in a horizontal state via the columns 6, and as described above, the waist bottom 3b is not affected by the ups and downs of the back bottom 3a, the knee bottom 3c, and the leg bottom 3d, and is kept horizontal. Since it is maintained, the patient can sit at the position of the waist bottom 3b without leaning.

[0008]

As described above, according to the present invention, the waist bottom corresponding to the waist is fixed to the bed frame in a horizontal state even when the floor undulating mechanism is activated to raise the back and raise the knee. Since the structure is maintained, the patient can sit without tilting the body, and the patient can easily move from the seated state to rehabilitation such as start-up training or transfer to a wheelchair or the like. The back can be raised and the knees can be raised only by the back raising mechanism, so that the mechanism can be simplified.
