[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottom structure for a bed which can be adapted to flexion of the body when raising the back and legs regardless of the size of the patient.

[0002]

2. Description of the Related Art Most of recent beds have a structure for raising a back and a mechanism for raising a leg, and a bed divided into a back bottom, a knee bottom and a leg bottom is undulated. By the way, it is important to set the length of the back bottom, the knee bottom, and the leg bottom in the longitudinal direction of the bed, and it is ideal that the knee joint of the patient and the joint between the knee bottom and the leg bottom are matched. is there. This is because if they do not conform, raising the back or raising the legs may cause a floor slip or slip.

[0003]

However, since the lengths in the longitudinal direction of the back bottom, knee bottom, and leg bottom that match are different depending on the physique of the patient, it is necessary to adapt the patient's body to the undulations of the bed bottom. Had to make a compromise to some extent by adjusting with various auxiliary equipment and preparing beds with different standards. The present invention has been made to solve such problems, and an object of the present invention is to provide a bottom structure for a bed that does not depend on the physique of the patient.

[0004]

In order to solve the above-mentioned problems, the present invention divides a floor portion into a back bottom, a knee bottom and a leg bottom, and forms the knee bottom and the leg bottom with a plurality of strips. It has a structure that is connected by a bottom
Guide frames are provided on both sides of the knee bottom corresponding to the bed width direction, and the guide plate holds a receiving plate having a curved surface movably, and the curved portion of the receiving plate is one of a plurality of strip-shaped bottoms. It is characterized in that the strip-shaped bottom is held by abutting against. In the above configuration, the elongated hole is formed in the guide frame, while the tip end of the protruding piece provided on one end side of the receiving plate on the bed longitudinal direction side is bent and the tightening bolt is attached to the elongated hole. It is configured to be inserted and attached to the tip end portion of the projecting piece through. In addition, a receiving frame and a fitting protrusion that fits into the receiving frame may be integrally formed on the knee bottom, the plurality of strip-shaped bottoms, and the leg bottom at positions facing each other. Further, a cover may be attached to both ends of the knee bottom in the bed width direction, and a guide frame for movably holding the receiving plate may be attached to the cover.

[0005]

[Operation] The backing plate, along the guide frame on the knee bottom,
It can be moved within the range of the long hole, and the curved bottom can be held by bringing the curved portion into contact with any of the plurality of strip-shaped bottoms. Therefore, when raising the legs together with raising the back, the bending positions of the knee bottom and the leg bottom change, and the length of the thigh due to the difference in the patient's physique, that is, the knee bottom at the knee joint part. It is possible to adapt the bending position with the leg bottom. Further, if the knee bottom, the plurality of strip-shaped bottoms and the leg bottom are integrally formed with the connecting means at the positions to be connected to each other, the ordinary connecting parts are not necessary, and the number of components is reduced. You can

【Example】

Next, a bottom structure of a bed according to the present invention will be described below with reference to the accompanying drawings, with reference to an embodiment. In FIG. 1, reference numeral 1 indicates a bed bottom 1, which is divided into a back bottom 2, a knee bottom 3 and a leg bottom 4, and the knee bottom 3 and the leg bottom 4 are separated into a plurality of strips. And the guide plates 6 are provided on both sides of the knee bottom 3 corresponding to the bed width direction, and the receiving plate 7 having a curved surface is movably held on the guide frames 6 and The curved portion 8 of the plate 7 is brought into contact with any of the plurality of strip-shaped bottoms 5 to hold the strip-shaped bottoms 5.

In such a structure, the elongated hole 9 is formed in the guide frame 6, while the tip end portion 11 of the projecting piece 10 provided on one end side of the receiving plate 7 in the longitudinal direction of the bed is bent and tightened. The bolt 12 is configured to be inserted and attached to the tip portion 11 of the projecting piece 10 through the elongated hole 9.

The strip-shaped bottoms 5 interposed between the knee bottoms 3 and the leg bottoms 4 are flexibly connected by hinges 13. The strip bottoms 5 may be manufactured by blow molding (see FIG. 2).

The bottom structure of the bed according to the present invention is constructed as described above, and its operation will be described below. The backing plate 7 is a guide frame 6 on the knee bottom 3.
The strip-shaped bottom 5 can be held by contacting the curved portion 8 with any of the strip-shaped bottoms 5 and moving the strip-shaped bottom 5 in the range of the slot 9. Therefore, when the legs are raised together with the back raising, the knee bottom 3 and the leg bottom 4 are
The bending position is changed, and the length of the thigh due to the difference in the physique of the patient, that is, the knee bottom 3 at the knee joint part.
And the bending position of the leg bottom 4 can be adapted (see FIGS. 3 and 5). For example, when the patient is a small person such as an elderly person, a woman, or a child, the backing plate 7 is brought close to the connecting portion side between the back bottom 2 and the knee bottom 3. In this case, the bending portion 8 abuts on the strip-shaped bottom 5 on the side of the connecting portion with the knee bottom 3, and when the knee is raised, the knee bottom 3 and the strip-shaped bottom 5 are bent following the receiving plate 7 ( (See FIG. 4). On the other hand, when the patient is large, such as an adult male, the receiving plate 7 may be moved along the guide frame 6 to the side where the knee bottom 3 and the strip bottom 5 are connected (see FIG. 6).

Next, another embodiment of the bottom structure of the bed according to the present invention will be described. In the bottom 20 in this case, as shown in FIG. 7, the knee bottom 2 is divided and formed.
2, a plurality of strip-shaped bottoms 23 and leg bottoms 24, and a C-shaped receiving frame 25 integrally formed at respective locations to be connected to each other, and a projection shaft-like portion 26 fitted to the C-shaped receiving frame 25. And are configured to be bendable (see FIG. 8). The knee bottom 22, the plurality of strip-shaped bottoms 23, and the leg bottoms 24 are made of extrusion-molded hollow resin, and covers 27, 28, and 29 are provided at both ends in the bed width direction, respectively. . The cover 27 of the knee bottom 22 has a guide frame 30 for movably holding the receiving plate 7, and an elongated hole 31 in the guide frame 30.

According to this embodiment, it is possible to reduce the number of components by eliminating the need for connecting members.

[0012]

As described above, according to the present invention, the bending positions of the knee bottom and the leg bottom are changed, and the length of the thigh due to the difference in the physique of the patient, that is, the knee joint part. It is possible to adapt the bending position of the bottom and the leg bottom, it can follow the knee joint of the body regardless of the physique of the patient, and it can hold the body sufficiently, so that no deviation is felt, Comfortable bed.
