The panel member 16 has the same shape and the same size over the entire length in the left-right direction in a cross section orthogonal to the left-right direction. The panel member 16 is formed by extrusion molding in which a molding material such as synthetic resin or light metal is extruded in the left-right direction (panel longitudinal direction).

  The panel member 16 includes a panel body 50 and reinforcing ribs 51. The panel body 50 forms the outer surface of the panel member 16. The panel body 50 is formed in an inverted isosceles trapezoidal shape when viewed from the front in the left-right direction. The lower surface of the panel body 50 is smaller than the upper surface of the panel body 50 in the front-rear direction. The lower surface serves as a mounting surface 16a that faces the members to be connected 32, 39 (the first connected member 32 and the second connected member 39) in the panel member 16. The panel body 50 is formed in a hollow shape that is open on both sides in the left-right direction.

  The reinforcing rib 51 is provided in the panel body 50 over the entire length of the panel body 50 in the left-right direction. The reinforcing rib 51 connects the upper surface and the lower surface of the panel body 50. The reinforcing rib 51 is formed in a plate shape that extends linearly in the up-down direction when viewed from the front when viewed from the left-right direction.

  Between the panel member 16 and the members to be connected 32, 39, there is provided a connecting means 52 capable of commonly connecting the panel members 16 of various forms having different lengths to the members to be connected 32, 39. The connecting means 52 can connect the panel member 16 to the connected members 32 and 39 of the same form regardless of the length of the panel member 16. The connecting means 52 can connect the connected members 32 and 39 to the panel members 16 having different lengths without changing the form of the connected members 32 and 39.

  In the illustrated example, a screw member 53 is used as the connecting means 52. The screw member 53 is inserted from below the connected members 32 and 39 upward through the connected members 32 and 39. The screw member 53 integrally penetrates the connected members 32 and 39 and the lower surface (mounting surface 16a) of the panel body 50 in the vertical direction. The screw member 53 is screwed into the through hole formed in the mounting surface 16a, and the connecting means 52 connects the panel member 16 to the connected members 32 and 39 by screwing. The screw member 53 is screwed into the mounting surface 16a while being screwed to form a screw member (screw) that connects the panel member 16 to the connected members 32 and 39. As the connecting means 52, a driving tack (not shown) may be adopted instead of the screw member 53.

  Next, a method of manufacturing the bed device 10 will be described.

  First, the width, which is the size of the bed surface 15 in the left-right direction, is determined. In the bed device 10 of the present embodiment, the bed surface 15 has a narrow width W1 as shown in FIG. 8A or the bed surface 15 has a wide width W2 as shown in FIG. 8B. Either form can be formed.

  In addition, a long member that becomes the panel member 16 is extrusion molded. 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 frame 12 is formed. At this time, a common configuration is adopted for the structure of the support base 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 have a form in which the size in the left-right direction is adjusted according to the width dimension of the bed surface 15. Further, 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 base 12. At this time, the panel member 16 is connected to the connected members 32 and 39 via the connecting means 52.
By the above, the said bed apparatus 10 is formed.

As described above, according to the bed apparatus 10 according to the present embodiment, since the connecting means 52 is provided between the panel member 16 and the connected members 32 and 39, the panel members having different lengths in the left-right direction. Even if it is 16, it can be attached to the support frame 12 having the common connected members 32 and 39 via the connecting means 52. Therefore, the bed 11 of various sizes can be adopted while suppressing the 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 panel member 16 has the same size and shape when viewed in a cross section orthogonal to the left-right direction over the entire length in the left-right direction, any connected member 32 of the panel members 16 having a different length can be used. , 39 can be made equivalent in form. Therefore, even panel members 16 having different lengths can be attached to the support pedestal 12 having the connected members 32 and 39 in common, and the size of the support pedestal 12 can be suppressed while changing the shape. The bed 11 can be adopted.
Further, since the above-described dimensions and shape of the panel member 16 are equal 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 portion of the panel member 16 in the left-right direction, even when the panel member 16 is opened outward in the left-right direction as in the present embodiment, for example. The end of the panel member 16 can be covered by the cover member 17 from the outside in the left-right direction.
Further, since the plurality of panel members 16 form the back bottom 18 and the leg bottom 19, even in the bed apparatus 10 having the back raising function and the leg raising function as in the present embodiment, the support platform 12 is provided. The bed 11 of various sizes can be adopted while suppressing the change of the form.

  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.

For example, as the panel member 16 and the connecting means 52, it is also possible to adopt a configuration as shown in FIG.
As shown in FIG. 9, the panel member 16 is provided with a concave groove portion 54 formed along the left-right direction (panel longitudinal direction). The groove 54 crosses the mounting surface 16a in the left-right direction. The groove 54 is recessed upward from the mounting surface 16a. A widened portion 55 is provided at an intermediate portion in the vertical direction of the concave groove portion 54. The widened portion 55 is wider in the front-rear direction than the other portions of the concave groove portion 54.
Then, at least a part of the connecting means 52 is arranged in the concave groove portion 54 while being locked in the concave groove portion 54. As the connecting means 52, a bolt 56 (screw attachment member) and a nut 57 that are screwed with each other are adopted. In the illustrated example, the nut 57 is arranged in the widened portion 55. The size of the nut 57 in the front-rear direction is larger than the size of the recessed groove portion 54 in the front-rear direction except the widened portion 55. As a result, the nut 57 is restricted from separating downward from the widening portion 55. The bolt 56 is inserted from below the connected members 32, 39 into the groove 54 through the connected members 32, 39, and is screwed into the nut 57.
