2. Description of the Related Art Conventionally, in a bed having a so-called gatch mechanism (back raising mechanism, knee raising mechanism), when raising the back, the bottom corresponding to the back is tilted and adjusted.
He has raised his head with his back to achieve the desired posture. In other words, when raising the back, the head side is also inclined at the same angle as the back side, so that the positional relationship between the head side and the back side remains unchanged. By the way, of the bottoms corresponding to the back, the function to make the bottom supporting the head side slightly inclined (up) is required. If such a function is available, raise the head and shoulders slightly while sleeping. It has been found to be very helpful when caregivers reach under the shoulders when they need to, or when they are turning over.

[0003]

However, in order to raise the head to the back, hitherto, the user has to do it by himself or insert a pad or the like under the head. The present invention has been proposed in view of the above background, and it is an object of the present invention to provide a bed having a head bottom with a tilt function that has a simpler structure and can take a comfortable posture. Aim.

[0004]

In order to solve the above-mentioned problems, the present invention divides a bottom corresponding to an upper body into a head bottom supporting a head side and a back bottom corresponding to a back in a bed. The head-side bottom is connected to the back bottom so that the head-side bottom can be raised and lowered, and the head-side bottom and the back bottom are connected by a first stay and a second stay that are connected to each other so as to be bendable. The total length of the first stay and the second stay is set to be larger than the linear distance between the attachment points of the head-side bottom and the back bottom where the combined first and second stays are attached. Between the second stay and the second stay, an urging means for urging the first stay and the second stay to bend at all times is interposed, and the first stay or the second stay is provided with the urging means. An operating means for selectively bending the first stay and the second stay in any one of two directions is provided under the force, and the operating means is operated under the urging of the urging means, whereby the first stay is operated. Further, the head-side bottom is adjusted so as to be able to switch up and down with respect to the back bottom via the second stay.
In addition, the present invention, at least in a bed provided with a back raising mechanism, the bottom corresponding to the upper body is divided into a head bottom supporting the head side and a back bottom corresponding to the back, and the head bottom is positioned with respect to the back bottom. The head-side bottom and the back bottom are connected to each other by a first stay and a second stay that are flexibly connected to each other, and the total length of the first and second stays connected to each other. Is larger than the linear distance between the attachment points of the head-side bottom and the back bottom where the combined first and second stays are attached, and the first stay is provided between the first and second stays. And a second stay are interposed by an urging means for urging the second stay to bend at all times.
On the stay or the second stay, under the urging of the urging means,
An operating means for selectively bending the first stay and the second stay in either direction is provided, and the operating means is operated under the urging of the urging means regardless of whether the back bottom is raised or lowered. In this way, the head-side bottom is adjusted to be undulated with respect to the back bottom via the first stay and the second stay.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of a bed having a head-side bottom having a tilt function according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 shows a bottom 2 corresponding to the upper body of the bottom of a bed 1 provided with a back raising mechanism (not shown). Here, the bottom 2 corresponding to the upper body is divided into a head-side bottom 2a corresponding to the head and a back bottom 2b corresponding to the back,
The head-side bottom 2a is rotatably connected to the back bottom 2b so as to take an elevation angle. Also, this head side bottom 2a
And the back bottom 2b are attached to the mounting members 3, 4 protruding from the back side.
Are connected via a first stay 5 and a second stay 6 rotatably connected to each other. In this case, the linear distance between the mounting members 3 and 4 projecting from the back side of the head bottom 2a and the back bottom 2b is set to be shorter than the total length of the connected first stay 5 and second stay 6. The connected first stay 5 and second stay 6 are always mounted in a state of being bent around the connection point.

The first stay 5 and the second stay 6
Are provided with tension springs 7 for urging them toward each other, and a first stay 5 and a second stay 6 are provided on the second stay 6 side against the urging force of the tension springs 7. Is provided with an operation lever 8 for performing a displacement operation on the connection point as a center. The first stay 5 and the second stay 6 are provided between the mounting members 3 and 4 projecting from the back side of the head-side bottom 2a and the back bottom 2b for mounting the first stay 5 and the second stay 6. A toggle force is generated around the connecting point under the urging of the tension spring 7 with the connecting straight line L as a boundary, and it is bent bidirectionally (upwardly convex and downwardly convex in the figure). Like that. Further, on the back side of the back bottom 2b, in order to regulate the bending operation of the first stay 5 and the second stay 6, an operation is performed so as to match the operating position of the connecting position between the first stay 5 and the second stay 6. A regulating member 9 is provided to protrude. In order to inform the operation end of the operation lever 8 to set the operation stroke of the operation lever 8 and to notify the end of the operation by abutting a connection portion between the first stay 5 and the second stay 6. The middle and upper and lower end portions 9a and 9b are provided (see FIG. 2).
In this case, the operating lever 8 is operated under the urging of the tension spring 7 so that the connecting portion between the first stay 5 and the second stay 6 is brought into contact with the upper regulating end portion 9a of the operation regulating member 9. Therefore, the head-side bottom 2a is set so as to be inclined by about 15 ° with respect to the back bottom 2b via the first stay 5. On the other hand, by operating the operation lever 8 in the reverse direction, the connecting portion of the first stay 5 and the second stay 6 is brought into contact with the lower regulating end portion 9b of the operation regulating member 9 to thereby make the first stay. The head-side bottom 2a is set so as to be flat with respect to the back bottom 2b via the base 5 (see FIG. 3).

The bed according to the present invention having the head-side bottom having the tilt function is configured as described above. Next, the operation of the bed will be described. First, the operation lever 8
Is displaced in the counterclockwise direction as shown in FIG. 4, and the connecting portion between the first stay 5 and the second stay 6 is brought into contact with the lower regulating end portion 9 b of the operation regulating member 9, and Assuming that the bottom 2a is flat with respect to the back bottom 2b, the patient P on the mattress M is in a state in which the head is straight on the body as shown in FIG. In this state, if a linear drive mechanism (not shown) connected to the back raising arm 10 protruding from the back bottom 2b is activated, the head is raised with the head straight to the body. .

Then, when the operation lever 8 is operated clockwise in the figure against the urging force of the tension spring 7, the connecting portion between the first stay 5 and the second stay 6 becomes an operation regulating member 9 Since the first stay 5 and the second stay 6 are displaced linearly from the bent state, the mounting members 3 and 4 projecting from the back side of the head-side bottom 2a and the back bottom 2b are moved upward. ,
A toggle force is exerted to expand the space between the mounting members 3 and 4. Thus, the head-side bottom 2a is inclined with respect to the back bottom 2b via the first stay 5. And the first
The connecting point between the stay 5 and the second stay 6 is the head-side bottom 2a.
When a straight line L connecting the attachment members 3 and 4 projecting from the back side of the back bottom 2b is passed, the first stay 5 and the second stay 6 are bent to the opposite sides by the biasing force of the tension spring 7 this time. In this manner, the connecting portion comes into contact with the upper regulating end portion 9a of the operation regulating member 9, thereby tilting the head-side bottom 2a through the first stay 5 by about 15 ° with respect to the back bottom 2b. (See FIG. 5). The connection between the first stay 5 and the second stay 6 is the head-side bottom 2.
a and the attachment members 3, 4 protruding from the back bottom 2b on the back side.
When crossing the straight line L connecting between them, the urging force on the first stay 5 and the second stay 6 is switched, so that when the operation is performed,
It is possible to give a sense of articulation, and it is possible to catch the completion of the operation by abutting on the upper regulating end portion 9a of the operation regulating member 9.

As described above, the head-side bottom 2a can be easily inclined with respect to the back bottom 2b, and the operation mechanism is completely independent of the back-raising mechanism. It is possible to freely perform the undulating operation even in a flat state or an inclined state. When the head is raised by activating the above-described linear drive mechanism while the head-side bottom 2a is inclined by about 15 ° with respect to the back bottom 2b, for example, as shown in FIG. When tilted up to a maximum of 75 °, the head-side bottom 2a can be raised substantially by 90 °.

[0010]

As described above, according to the present invention, the effect of the headrest can be provided by a simple mechanism, and furthermore, since it is constituted as a mechanism independent of the back-raising mechanism, the adjustment angle of the bottom can be adjusted. Regardless, the tilt operation of the head-side bottom becomes possible. Further, since the mechanism is configured as an independent mechanism from the back raising mechanism, there is an effect that the present invention can be applied to an existing bed by replacing the entire bottom supporting the upper body.
