Within the length direction L, the direction from the center of the bed apparatus toward the head side or the foot side is referred to as the "outer side L". out ", and the direction from the head or foot side toward the center of the bed device is called "inward L in "It is also called.

[0010] <First embodiment> A nursing bed apparatus according to this embodiment will be described. FIG. 1 is a perspective view showing a bed apparatus according to this embodiment, as viewed obliquely from above. FIG. 2 is a perspective view showing the bed apparatus according to this embodiment, seen obliquely from below.

[0011] As shown in Figs. 1 and 2, a nursing bed apparatus according to this embodiment (hereinafter simply referred to as "bed apparatus 1") is provided with a lower frame 11. The lower frame 11 serves as a support for the entire bed apparatus 1, and is formed, for example, in a rectangular shape by combining metallic cylindrical members. Foot members 12 are provided at the four corners of the lower frame 11. The foot members 12 extend downward from the lower frame 11. The lower ends of the foot members 12 contact the floor surface of the room. Casters (not shown) may be attached to the corners of the lower frame 11 instead of the foot members 12.

[0012] A driving means is attached to the lower frame 11. The driving means includes a plurality of actuators 13. An upper frame 15 is provided on the lower frame 11. The upper frame 15 is also formed by combining cylindrical members made of metal, for example. The upper frame 15 is capable of being displaced in the vertical direction V by the driving means including the actuators 13.

[0013] A bottom 16 is provided on the upper frame 15. The bottom 16 is provided with a back bottom 16a, a waist bottom 16b, a knee bottom 16c, and a foot bottom 16d in this order from the head side to the foot side. The waist bottom 16b is fixed to the upper frame 15. The back bottom 16a, the knee bottom 16c, and the foot bottom 16d can be tilted by a driving means including an actuator 13.

[0014] A bed board 17 is attached to each of the head side and foot side of the upper frame 15. The bed board 17 is a substantially rectangular plate-like member, and is detachable from the upper frame 15. When the bed board 17 is attached to the upper frame 15, the bed board 17 extends mainly upward from the upper frame 15.

[0015] Hereinafter, the lower frame 11, the leg members 12, the drive means including the actuator 13, the upper frame 15, and the bottom 16 will be collectively referred to as the "bed body 10." Moreover, when viewed from the bed board 17, the side of the bed body 10 will be referred to as the "inside" and the opposite side will be referred to as the "outside."

[0016] Two option receiving members 18 are attached to each of the right and left sides of the upper frame 15. On each of the right and left sides of the upper frame 15, the option receiving members 18 are disposed on the head side and the foot side. In other words, a total of four option receiving members 18 are provided in the bed apparatus 1. The option receiving members 18 are members to which options such as side rails are attached.

[0017] Next, the configuration of the bed board will be described in detail. FIG. 3 is a perspective view showing the bedboard according to the present embodiment. FIG. 4 is a front view showing the bedboard according to this embodiment as viewed from the inside. FIG. 5 is a top view showing the bedboard according to this embodiment. FIG. 6 is a side view showing the bedboard according to this embodiment. FIG. 7 is an end view showing the dimensions of each part of the bedboard according to this embodiment. FIG. 8 is an end view showing the relationship between the outer and inner dimensions of the bed apparatus according to this embodiment.

[0018] As shown in Figs. 1 and 2, the shapes of the two bed boards 17 provided in the bed apparatus 1 are mirror images of each other. As shown in Figs. 3 to 6, each bed board 17 is provided with a plate member 20, a grip member 30, and a pair of mounting brackets 40. The plate member 20 and the grip member 30 are collectively referred to as the "board main body." The plate member 20 is made of a material harder than the grip member 30. The plate member 20 is made of wood, for example, MDF (Medium-Density Fiberboard). The grip member 30 is made of resin, for example. The mounting brackets 40 are made of a metal material, for example, steel.

[0019] The plate member 20 is a plate-like member, and its shape is a hexagon with two diagonal corners cut off from a rectangle. That is, the plate member 20 has a first main surface 21 and a second main surface 22 as main surfaces. When the bed board 17 is attached to the bed body 10, the first main surface 21 faces inward, i.e., toward the bed body 10, and the second main surface 22 faces outward.

[0020] The plate member 20 has an upper surface 23, a lower surface 24, a first side surface 25, a second side surface 26, a first inclined surface 27, and a second inclined surface 28 as end surfaces. When the bed board 17 is attached to the bed body 10, the upper surface 23 faces upward, the lower surface 24 faces downward, the first side surface 25 faces one side in the width direction W, and the second side surface 26 faces the other side in the width direction W. The first inclined surface 27 is located between the upper surface 23 and the first side surface 25. The second inclined surface 28 is located between the lower surface 24 and the second side surface 26. For example, the upper surface 23 and the lower surface 24 are parallel to each other, the first side surface 25 and the second side surface 26 are parallel to each other, and the first inclined surface 27 and the second inclined surface 28 are parallel to each other.

[0021] The grip members 30 are provided on the upper surface 23, the first inclined surface 27, and the first side surface 25 of the plate member 20. On the other hand, the grip members 30 are not provided on the lower surface 24, the second side surface 26, and the second inclined surface 28 of the plate member 20. Therefore, the shape of the grip members 30 is generally L-shaped. In this embodiment, the lower surface 24, the second side surface 26, and the second inclined surface 28 of the plate member 20 are not covered by the grip members 30 and are exposed.

[0022] In other words, the grip member 30 has a first gripping portion 31 arranged on the upper surface 23, a second gripping portion 32 arranged on the first side surface 25, a third gripping portion 33 and a fourth gripping portion 34 arranged on the first inclined surface 27 and spaced apart from the first inclined surface 27, and a covering portion 35 arranged on the first inclined surface 27 and in contact with the first inclined surface 27. The third gripping portion 33 and the fourth gripping portion 34 form a grip portion 38. The grip portion 38 is spaced apart from the first inclined surface 27, and a gap 39 is formed between the first inclined surface 27 and the grip portion 38.

[0023] When viewed from the first main surface 21 side, the third gripping portion 33 is on an extension of the first gripping portion 31. The fourth gripping portion 34 is on an extension of the second gripping portion 32. The third gripping portion 33 is in contact with and connected to the first gripping portion 31 and the fourth gripping portion 34. The fourth gripping portion 34 is in contact with and connected to the second gripping portion 32 and the third gripping portion 33. In this way, the first gripping portion 31, the third gripping portion 33, the fourth gripping portion 34 and the second gripping portion 32 are provided continuously.

[0024] Additionally, covering portion 35 is continuous with first gripping portion 31 and second gripping portion 32. As a result, covering portion 35, third gripping portion 33, and fourth gripping portion 34 surround gap 39. When viewed from the first main surface 21 side, third gripping portion 33 and fourth gripping portion 34 are perpendicular to each other in a curve, and gap 39 has a shape of a substantially right-angled triangle.

[0025] As shown in FIG. 7, the thickness A of the grip member 30 is larger than the thickness B of the plate member 20. Here, the "thickness" refers to the length in the direction from the first main surface 21 to the second main surface 22, and refers to the length in the length direction L when the bed board 17 is attached to the bed device 1. The plate member 20 is preferably thin from the viewpoint of weight reduction and cost reduction, but is preferably thick from the viewpoint of strength. Also, as shown in FIG. 8, when the bed device 1 is installed, the outer dimension F of the bed device 1 in the length direction L is preferably as short as possible to save space, but the inner dimension G, which is the living space, is preferably as long as possible to improve livability. In order to satisfy both of these requirements, it is preferable that the difference (FG) between the outer dimension and the inner dimension is as small as possible, and therefore the plate member 20 is preferably thin. For example, the bed board of the conventional nursing bed disclosed in Patent Document 1 is formed in a thin box shape, so the entire bed board is thick and the difference (FG) between the outer dimension and the inner dimension is large. In contrast, in the bed apparatus 1 of this embodiment, the difference (FG) between the outer dimension and the inner dimension is determined by the thickness B of the board member 20. The board member 20 is made of wood, for example, MDF (Medium-Density Fiberboard), so that it is possible to make the board member 20 as thin as possible while ensuring the strength of the board member 20. In one example, the thickness B of the board member 20 is 20 mm.

[0026] Since the grip member 30 is the part that is held by the user, it is preferable that it is somewhat thick from the viewpoint of ease of gripping. Also, from the viewpoint of design, it is preferable that it is somewhat thick. Therefore, the thickness A is made larger than the thickness B. In one example, the thickness A of the grip member 30 is 30 mm. Therefore, the grip member 30 protrudes toward the first main surface 21 side and the second main surface 22 side with respect to the plate member 20.

[0027] However, in the bedboard 17 according to this embodiment, the amount of projection C of the grip member 30 toward the first main surface 21 side relative to the board member 20 is greater than the amount of projection D toward the second main surface 22 side. In one example, the amount of projection D toward the second main surface 22 side is set to a minimum value for maintaining the strength of the grip member 30, and the amount of projection C toward the first main surface 21 side is set to C=ABD.

[0028] Handle portion 38 (third gripping portion 33 and fourth gripping portion 34) is inclined toward first main surface 21 relative to first gripping portion 31 and second gripping portion 32. The portion of handle portion 38 that is farthest from first main surface 21 is, for example, the boundary portion between third gripping portion 33 and fourth gripping portion 34. A distance E (see FIG. 5 ) between first main surface 21 and the portion of handle portion 38 that is farthest from first main surface 21 is equal to or less than the thickness B of plate member 20.

[0029] 3 and 4, the pair of mounting brackets 40 are attached to the lower part of the first main surface 21 of the plate member 20. The pair of mounting brackets 40 are spaced apart from each other in the direction from the first side surface 25 to the second side surface 26. The mounting brackets 40 are for attaching the bed board 17 to the upper frame 15 of the bed body 10.

[0030] As shown in Fig. 1, in the bed apparatus 1 according to this embodiment, a bed board 17 is attached to each of the head side and the foot side of the bed body 10. The provision of the bed board 17 prevents the bedding from shifting position and gives the user a sense of security. In addition, when the user walks around the bed apparatus 1 or stands up from the bed apparatus 1, the user can support his / her body by grasping the grip member 30 of the bed board 17.

[0031] For example, when the user walks around the bed apparatus 1, the user grasps the first gripping portion 31, the second gripping portion 32, or the handle portion 38 of the grip member 30 from above to maintain the balance of the body. When the user stands up from the bed apparatus 1, the user grasps the handle portion 38 from inside the bed apparatus 1. Then, a downward force is applied to the handle portion 38. At this time, the wrist may or may not be passed through the gap 39 from below. This allows the user to stand up using the strength of both the legs and arms.

[0032] Next, the effects of this embodiment will be described. 9(a) and (b) are schematic end views showing a state in which a user grasps the grip member of a bed board, (a) showing this embodiment and (b) showing a reference example. 10(a) and (b) are perspective views showing a method of attaching a bed board in the nursing bed apparatus according to this embodiment. Figure 11(a) is a schematic front view showing the foot side bedboard, (b) is a schematic front view showing the head side bedboard, (c) is a schematic front view showing the foot side bedboard and the head side bedboard stacked together, and (d) is a schematic side view thereof.

[0033] As shown in Fig. 7, in the bedboard 17 according to this embodiment, the amount of projection C of the grip member 30 toward the first main surface 21 side relative to the board member 20 is larger than the amount of projection D toward the second main surface 22 side. out The grip member 30 protrudes toward the second main surface 22 side, preventing the overall length of the bed apparatus 1 from becoming longer. Since the thickness A of the grip member 30 is sufficiently large, the user can easily grasp the grip member 30, and the bed apparatus 1 has a high design quality. Meanwhile, by keeping the protrusion amount D toward the second main surface 22 small, the grip member 30 can prevent the overall length of the bed apparatus 1 from becoming longer, thereby saving space in the bed apparatus 1. When the bed apparatus 1 is installed in an ordinary house, the advantage of saving space is particularly large.

[0034] Furthermore, by using wood as the material for the board member 20 of the bed board 17, the thickness B of the board member 20 can be reduced while realizing a certain strength, compared to when resin is used. This allows the bed apparatus 1 to be made smaller, lighter, and less expensive. Also, compared to when metal is used as the material for the board member 20, the weight can be reduced. Furthermore, by using wood, when the bed apparatus 1 is installed in a general residence, the interior of the room is not marred. On the other hand, by using resin as the material for the grip member 30, the degree of freedom of the shape of the grip member 30 is improved, and the grip member 30 can be made lighter.

[0035] In the bedboard 17 according to this embodiment, as shown in Figures 3 to 6, the handle portion 38 of the grip member 30 is inclined toward the first main surface 21. As a result, when the bedboard 17 is attached to the bed apparatus 1, the handle portion 38 is inclined toward the inside of the bed apparatus 1.

[0036] 9(a), even when the user P inserts his / her wrist into the gap 39 from below to grasp the grip portion 38 (the third grip portion 33 and the fourth grip portion 34) in order to stand up from the bed apparatus 1, he / she does not need to bend his / her wrist significantly and can easily apply force downward. Thus, according to this embodiment, it is possible to effectively support the user in standing up.

[0037] In contrast, as shown in FIG. 9(b), if the third gripping portion 33 and the fourth gripping portion 34 were not inclined toward the inside of the bed apparatus, the user P would have to bend his or her wrist significantly in order to insert his or her wrist into the gap 39 and grasp the handle portion 38, making it difficult to apply force.

[0038] In addition, in the bed apparatus 1 according to this embodiment, the shape of the bed board 17 arranged on the head side and the shape of the bed board 17 arranged on the foot side are mirror images of each other. Therefore, as shown in Figures 10(a) and 10(b), by interchanging the bed board 17 on the head side with the bed board 17 on the foot side, the position of the grip member 30 can be switched between the right side and the left side of the bed apparatus 1. In other words, when switching the position of the grip member 30 between the right side and the left side of the bed apparatus 1, there is no need to prepare a separate bed board.

[0039] That is, in the state shown in Fig. 10(a), the grip member 30 is disposed on the right side of the bed apparatus 1 on both the head side bed board 17 and the foot side bed board 17. By switching the head side bed board 17 and the foot side bed board 17 from this state, the grip member 30 is disposed on the left side of the bed apparatus 1 on both the head side bed board 17 and the foot side bed board 17, as shown in Fig. 10(b).

[0040] When the bed apparatus 1 is installed in a general residence, it is often installed against the wall of the room. In this case, since the user accesses the bed apparatus 1 only from the opposite side of the wall, the grip member 30 only needs to be provided on the opposite side of the wall. When changing the installation location of the bed apparatus 1, the position of the wall as seen from the bed apparatus 1 may change. In this case, the bed apparatus 1 according to this embodiment can change the position of the grip member 30 according to the installation location of the bed apparatus 1. In this case, since there is no need to prepare a separate bed board, the relocation work of the bed apparatus 1 can be completed on-site.

[0041] As described above, in this embodiment, the shape of the bed board 17 arranged on the head side and the shape of the bed board 17 arranged on the foot side are mirror images of each other. In addition, in each bed board 17, the second inclined surface 28 is provided diagonally from the first inclined surface 27. And, while the handle portion 38 is provided on the first inclined surface 27, nothing is provided on the second inclined surface 28, and it is a notch.

[0042] Therefore, when the head-side bed board 17 shown in Fig. 11(b) is half-rotated and stacked on the foot-side bed board 17 shown in Fig. 11(a), the handle portion 38 of one bed board 17 can be positioned in the cutout portion on the second slope 28 of the other bed board 17 as shown in Figs. 11(c) and (d), and the handle portion 38 of one bed board 17 does not interfere with the other bed board 17. This allows two bed boards 17 to be stacked compactly. As a result, the two bed boards 17 can be easily transported and the storage space can be saved.

[0043] <Second embodiment> FIG. 12 is a perspective view showing the bed apparatus according to this embodiment, as viewed obliquely from above. FIG. 13 is a perspective view showing a bed board according to the present embodiment.

[0044] 12 and 13, in the nursing bed apparatus 2 according to this embodiment, the bed body 10 is provided with two bed boards 19. The configuration of the bed body 10 is the same as that of the first embodiment.

[0045] The bed board 19 according to this embodiment will be described in detail below. The shapes of the two bed boards 19 provided in the bed apparatus 2 are mirror images of each other. Each bed board 19 is provided with a plate member 20a, a grip member 30a, and a pair of mounting brackets 40. The shape of each bed board 19 is symmetrical.

[0046] The plate member 20a is a plate-like member having a rectangular shape, that is, like the plate member 20 in the first embodiment, the plate member 20a has a first main surface 21 and a second main surface 22 as main surfaces, and an upper surface 23, a lower surface 24, a first side surface 25 and a second side surface 26 as end surfaces, but does not have a first inclined surface 27 and a second inclined surface 28 (see FIGS. 3 to 6).

[0047] Similarly to the grip member 30 in the first embodiment, the grip member 30a has a first gripping portion 31 disposed on the upper surface 23 and a second gripping portion 32 disposed on the first side surface 25. The grip member 30a also has an opposing gripping portion 37 disposed on the second side surface 26. On the other hand, the grip member 30a does not have a third gripping portion 33, a fourth gripping portion 34, or a covering portion 35 (see Figs. 3 to 6). One end of the second gripping portion 32 is continuous with the first gripping portion 31, and the other end of the second gripping portion 32 is continuous with the opposing gripping portion 37. Therefore, the grip member 30a has a rough U-shape.

[0048] The configuration of the mounting bracket 40 is the same as that of the first embodiment. Therefore, the bed board 19 according to this embodiment is compatible with the bed board 17 according to the first embodiment. That is, the bed board 17 can be attached to a certain bed body 10, and the bed board 19 can also be attached to the certain bed body 10. Also, the bed board 17 can be attached to one of the head side and the foot side of one bed body 10, and the bed board 19 can be attached to the other side.

[0049] In this embodiment, too, as shown in Fig. 7, the thickness A of the grip member is greater than the thickness B of the plate member. Moreover, the projection amount C of the grip member toward the first main surface 21 side relative to the plate member is greater than the projection amount D toward the second main surface 22 side. This makes it possible to prevent the overall length of the bed apparatus 2 from becoming long while making the grip member 30a sufficiently thick. The configuration and the effects of this embodiment other than those described above are the same as those of the first embodiment.

[0050] <Third embodiment> FIG. 14 is a perspective view showing a bedboard according to the present embodiment. As shown in Fig. 14, the bed board 50 includes a board main body 60 and a pair of mounting brackets 40. The board main body 60 corresponds to the board member 20 and the grip member 30 in the first embodiment. However, unlike the first embodiment, the board main body 60 is integrally formed from resin. The external shape of the board main body 60 is, for example, substantially the same as the external shape of the board member 20 and the grip member 30 combined in the first embodiment.

[0051] That is, the board main body 60 has a generally plate-like shape, and is a hexagon with two diagonal corners cut off from a rectangle. The board main body 60 has a first main surface 61 and a second main surface 62 as main surfaces. When the bed board 50 is attached to the bed body 10, the first main surface 61 faces inward and the second main surface 62 faces outward.

[0052] Moreover, the board main body 60 has, as end faces, an upper face 63, a lower face 64, a first side face 65, a second side face 66, a first inclined face 67, and a second inclined face 68. The first inclined face 67 is located between the upper face 63 and the first side face 65. The second inclined face 68 is located between the lower face 64 and the second side face 66.

[0053] A loop-shaped handle portion 70 is formed between the upper surface 63 and the first side surface 65 of the board body portion 60. The handle portion formed on the board body portion 60 is only one handle portion 70. The handle portion 70 is provided only on one end of the upper surface 63 of the board body portion 60, and is not provided on the other end. In other words, no loop-shaped handle portion is formed between the upper surface 63 and the second side surface 66 of the board body portion 60, between the lower surface 64 and the first side surface 65, or between the lower surface 64 and the second side surface 66. The amount of protrusion of the handle portion 70 toward the first main surface 61 is greater than the amount of protrusion of the handle portion 70 toward the second main surface 62.

[0054] The board main body 60 is formed with a first gripping portion 81 arranged on the top surface 63, a second gripping portion 82 arranged on the first side surface 66, a third gripping portion 83 in contact with the first gripping portion 81, and a fourth gripping portion 84 in contact with the second gripping portion 82. When viewed from the first main surface 61 side, the third gripping portion 83 is on an extension line of the first gripping portion 81, and the fourth gripping portion 84 is on an extension line of the second gripping portion 82. The grip portion 70 is formed by the third gripping portion 83 and the fourth gripping portion 84. The gap 79 of the loop-shaped grip portion 70 is surrounded by the first inclined surface 67, the third gripping portion 83, and the fourth gripping portion 84.
