Abstract

(57) [Abstract] [Purpose] Strip floor boards of different widths are selected and configured to be removable so that the overall length of the bottom can be changed. [Structure] The bottom 2 of the bed 1 is replaced by the back bottom 2
a, a waist bottom 2b, a knee bottom 2c and a leg bottom 2d. Further, the pipe frame 4 is divided corresponding to the divided bottom 2, and floor plates 3a, 3b and 3c having different widths are selectively and detachably mounted. The floor plates 3a to 3c are hollow members formed by blow molding. [Effect] The total length of the bottom can be adjusted. This means that by replacing the floorboards with different widths, it is possible to make adjustments that match the size of the patient's body, a good fit, and improved sleeping comfort.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bottom structure in a bed in which strip-shaped floorboards having different widths are selected and configured to be detachable so that the total length of the bottom is changed.

[0002]

[Prior Art]

 The bottom of a conventional bed consists of a flat plate, a plate made by press working a steel plate, a steel wire stretched in a grid on a frame member, and a steel wire. There is one formed in a net shape. Recently, a bed having such a structure, in which a bottom is divided into a back bottom, a knee bottom and a leg bottom, and a back raising mechanism and a knee raising mechanism are connected, has become widespread.

[0003]

[Problems to be solved by the device]

 However, in general, a bed is formed according to a predetermined standard size or the like, and naturally the entire length of one bed has a set size. Therefore, the total length of the bottom is set, and the back bottom, the knee bottom and the leg bottom also have the determined dimensions. For this reason, when raising the back or raising the knee, depending on the patient, the displacement state of the back bottom, knee bottom, and leg bottom may not match the body, resulting in poor fit and difficulty in use. Therefore, it was necessary to have beds with different standard dimensions. The present invention has been made in view of such a problem, and an object thereof is to provide a bottom structure in a bed in which floor plates having different widths are selectively attached and the total length of the bottom is changed to some extent.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides, at the bottom of a bed, a pipe frame provided on a main frame of the bed, and the pipe frame is provided with a plurality of strip-shaped floor plates having different widths selectively and It is characterized by being detachably attached. The bottom is divided into a back bottom, a waist bottom, a knee bottom and a leg bottom.

[0005]

[Action]

 According to the present invention, it is possible to adjust the total length of the bottom by replacing the strip-shaped floor plates with different widths and mounting them. This is also due to the fact that the back bottom, waist bottom, knee bottom and leg bottoms are formed by floorboards of different widths so that the patient's back-to-waist and hip-to-leg length adjustments can be made. It is possible and it is possible to improve the sleeping comfort.

【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. As shown in FIG. 1, the bottom 2 of the bed 1 is divided into a back bottom 2a, a waist bottom 2b, a knee bottom 2c and a leg bottom 2d, and is provided on the main body frame 3 of the bed 1. The floor frame 3a, 3b, 3c of different widths is detachably provided on a pipe frame (described later), and is connected to a back raising mechanism and a knee raising mechanism (not shown).

The floor plates 3a, 3b and 3c have a width relationship of floor plate 3a> floor plate 3b> floor plate 3c. The floor plate 3a is arranged on the pipe frame 4 near the headboard 5 and the footboard 6. The back bottom 2a is composed of a floor board 3a and two floor boards 3b, the waist bottom 2b is composed of a floor board 3b, the knee bottom 2c is composed of two floor boards 3c, and the leg bottom 2d is composed of a floor board 3c and a floor board 3a ( (See Figure 2). The floor plates 3a to 3c are hollow members formed by blow molding, and the pipe frame 4 is attached so as to be fitted into the recesses 7 formed in the floor plates 3a to 3c (see FIG. 3). . An operating arm 8 of a back raising mechanism (not shown) is in contact with the pipe frame 4 via a roller 9 on the back bottom 2a.

As shown in FIG. 4, the pipe frame 4 is divided into a back bottom 2a, a waist bottom 2b, a knee bottom 2c and a leg bottom 2d, like the bottom 2, and is divided into a back bottom receiving pipe 4a and a back bottom receiving pipe 4a. It comprises a waist bottom receiving pipe 4b, a knee bottom receiving pipe 4c, and a leg bottom receiving pipe 4d, which are sequentially connected.

According to the bottom structure as described above, the strip-shaped floor plates 3a to 3c can be selected and attached. For example, in the back bottom 2a, there are two floor boards 3a and 3b, in the waist bottom 2b the floor board 3b is the floor board 3c, and in the knee bottom 2c, there are two floor boards 3c. 3b, or the floor plate 3c and the floor plate 3a in the leg bottom 2d may be the floor plate 3a only. Thereby, the total length of the bottom 2 can be adjusted. This was also the patient's back-to-waist and hip-to-leg length by replacing the back bottom 2a, waist bottom 2b, knee bottom 2c and leg bottom 2d with floorboards of different widths. It is adjustable and fits well, improving sleep comfort. Furthermore, since the total length of the bottom 2 can be adjusted to some extent, it is not necessary to provide beds with different standard sizes. Since the floor plates 3a to 3c are hollow members formed by blow molding, good cushioning properties can be obtained with a simple structure.

[0010]

[Effect of the device]

 As described above, according to the present invention, it is possible to select and attach strip-shaped floor boards having different widths and to adjust the total length of the bottom. This also allows for adjustments to the patient's back-to-waist and hip-to-leg length by replacing the back bottom, hip bottom, knee bottom and leg bottom with floorboards of different widths. Yes, it has a good fit and can improve sleeping comfort. Therefore, it is not necessary to have beds with different standard sizes.
