In the bed device 10 of the present embodiment, the width W1 of the bed surface 15 is narrow as shown in FIG. 8A, and the width W2 of the bed surface 15 is wide as shown in FIG. 8B. Any form can be formed.

Further, a long member to be the panel member 16 is extruded. After that, the long member is cut in the longitudinal direction according to the width dimension of the bed surface 15 (bed 11) to form the panel member 16. A plurality of panel members 16 having the same length can be adopted for one bed device 10.

Further, the support pedestal 12 is formed. At this time, a common form is adopted for the configuration of the support pedestal 12 excluding the movable bar portion 35 and the fixed bar portion 37, regardless of the width dimension of the bed surface 15. The movable bar portion 35 and the fixed bar portion 37 adopt a form in which the size in the left-right direction is adjusted according to the width dimension of the bed surface 15. In addition, the board 13 and the drive mechanism 14 are formed. The board 13 and the drive mechanism 14 adopt a common form regardless of the width dimension of the bed surface 15. The board 13 can be changed according to the width dimension of the bed surface 15, and for example, a wide board can be adopted according to the width dimension of the bed surface 15.

Then, the panel member 16, the board 13, and the drive mechanism 14 are assembled to the support frame 12. At this time, the panel member 16 is connected to the connected members 32 and 39 via the connecting means 52.
As a result, the sleeper device 10 is formed.

Therefore, it is possible to adopt a bed 11 of various sizes while suppressing a change in the form of the support frame 12.
Further, since the connecting means 52 connects the panel member 16 to the connected members 32 and 39 by screwing, the panel member 16 can be easily connected to the connected members 32 and 39.

Further, since the dimensions and shapes of the panel member 16 viewed in a cross section orthogonal to the left-right direction are the same over the entire length in the left-right direction, any panel member 16 having a different length can be connected to the panel member 16. , The form of the portion connected to 39 can be made equivalent. Therefore, even panel members 16 having different lengths can be attached to the support pedestal 12 having the common connected members 32 and 39, and various sizes can be suppressed while suppressing the change in the form of the support pedestal 12. Bed 11 can be adopted.
Further, since the above-mentioned dimensional shape of the panel member 16 is the same over the entire length in the left-right direction, the panel member 16 can be easily formed by extrusion molding in which the molding material is extruded along the left-right direction.

Further, since the cover member 17 is provided at the end of the panel member 16 in the left-right direction, even when the panel member 16 is open to the outside in the left-right direction as in the present embodiment, for example. , The end portion of the panel member 16 can be covered from the outside in the left-right direction by the cover member 17.
Further, since the plurality of panel members 16 form the back bottom 18 and the leg bottom 19, the support pedestal 12 is also used in the bed device 10 having the back raising function and the leg raising function as in the present embodiment. It is possible to adopt sleepers 11 of various sizes while suppressing changes in the form of the bed.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
