Description

The present invention relates to a bed device.

In conventional bed devices, side rails are sometimes provided to prevent the user from falling off the mattress placed on the bed frame, or to prevent the mattress or futon from slipping off.

Generally, the side rails are supported by a side rail base attached to the side of the bed frame. For example, as disclosed in Patent Document 1, a bed device is also known that has a cover (panel) that covers the side of the side rail base (optional support) and exposes the top and bottom surfaces.

JP 2019-176959 A

When providing a cover on the side rail base, it is necessary to devise a structure for attaching the cover to the side rail base so that the cover does not come off when the bed device is in use.

There is also a demand for a bed device that allows the attachment position of the side rails to be adjusted according to the manner of use. In this case, further improvements will be required in the structure of the side rail base and cover.

There is also room for various improvements in bed devices to which side rails can be attached. Therefore, one of the objectives of the present invention is to improve the convenience of bed devices to which side rails can be attached.

According to one aspect of the embodiment, the bed device includes a bed frame having a first end and a second end in a first direction and a first side and a second side in a second direction intersecting the first direction, a side rail having legs, a side rail base provided on the first side, and a first cover and a second cover detachable from the first side rail base. The first side rail base has a first support hole and a second support hole into which the legs can be inserted. When the first cover is attached to the first side rail base, the first support hole is exposed from the first cover and the second support hole is blocked by the first cover. Also, when the second cover is attached to the first side rail base, the second support hole is exposed from the second cover and the first support hole is blocked by the second cover.

According to another aspect of the embodiment, the bed device includes a bed frame having a first end and a second end in a first direction and a first side and a second side in a second direction intersecting the first direction, a side rail having legs, a first side rail base provided on the first side, a second side rail base provided on the second side, and a first cover and a second cover detachable from both the first side rail base and the second side rail base. The first side rail base and the second side rail base each have a first support hole into which the legs can be inserted, and a second support hole located closer to the first end than the first support hole and into which the legs can be inserted. When the first cover is attached to the first side rail base and the second cover is attached to the second side rail base, the first support hole of the first side rail base and the second side rail base is exposed from the first cover and the second cover, respectively, and the second support hole of the first side rail base and the second side rail base is blocked by the first cover and the second cover, respectively. When the second cover is attached to the first side fence base and the first cover is attached to the second side fence base, the second support holes of the first side fence base and the second side fence base are exposed from the second cover and the first cover, respectively, and the first support holes of the first side fence base and the second side fence base are blocked by the second cover and the first cover, respectively.

According to yet another aspect of the embodiment, the bed device includes a bed frame that is elongated in a first direction and has a first side and a second side in a second direction intersecting the first direction, a side rail having legs, a first bracket provided on the first side, a second bracket provided on the second side, and a first side rail base and a second side rail base that can be connected to the first bracket and the second bracket and each have a support hole into which the legs can be inserted. The positions of the support holes when the first side rail base is connected to the first bracket and the second side rail base is connected to the second bracket are different in the first direction from the positions of the support holes when the first side rail base is connected to the second bracket and the second side rail base is connected to the first bracket.

The present invention can improve the convenience of a bed device to which side rails can be attached.

Some embodiments of the present invention will now be described with reference to the drawings.
In each embodiment, an electric bed capable of changing the shape of the floor surface (bed platform) is disclosed as an example of a bed apparatus. However, the configuration disclosed in each embodiment, particularly the structure related to the attachment of the side rails, can also be applied to other types of bed apparatuses, such as bed apparatuses that do not have electrical control elements.

[First embodiment]
Fig. 1 is a schematic perspective view of a bed apparatus 1 according to a first embodiment. Fig. 2 is a schematic top view of the bed apparatus 1. In the following description, a first direction X (longitudinal direction), a second direction Y (width direction), and a third direction Z (height direction) that intersect with each other as shown in each figure are defined. In this embodiment, these directions X, Y, and Z are perpendicular to each other.

The bed apparatus 1 includes a bed frame 2 that is long in a first direction X. The bed frame 2 has a first end E1 and a second end E2 in the first direction X, and a first side S1 and a second side S2 in the second direction Y. For example, the first end E1 is located at the head side of a user lying on his/her back on the bed apparatus 1, the second end E2 is located at the foot side of the user, the first side S1 is located at the left side of the user, and the second side S2 is located at the right side of the user.

The bed apparatus 1 has a number of floor plates 31, 32, 33, 34, 35, and 36 arranged on the bed frame 2. These floor plates 31, 32, 33, 34, 35, and 36 are lined up in this order from the first end E1 to the second end E2. Two adjacent floor plates are connected so as to be rotatable about an axis parallel to the second direction Y. When the bed apparatus 1 is in use, a mattress is placed on the floor plates 31, 32, 33, 34, 35, and 36.

The bed device 1 further includes a first side rail base 4A, a second side rail base 4B, a third side rail base 4C, and a fourth side rail base 4D for supporting the side rails 9 (see FIG. 3) described below. These side rail bases 4A, 4B, 4C, and 4D are formed, for example, from a metal material.

The first side fence base 4A is provided at a position close to the first end E1 on the first side S1 and is covered by a first cover 5A. The second side fence base 4B is provided at a position close to the first end E1 on the second side S2 and is covered by a second cover 5B. The third side fence base 4C is provided at a position close to the second end E2 on the first side S1 and is covered by a third cover 5C. The fourth side fence base 4D is provided at a position close to the second end E2 on the second side S2 and is covered by a fourth cover 5D. These covers 5A, 5B, 5C, 5D are formed, for example, from a resin material.

As shown in FIG. 2, the bed device 1 further includes a first board base 61, a second board base 62, a headboard 71, and a footboard 72. The first board base 61 is attached to a first end E1. The second board base 62 is attached to a second end E2.

The headboard 71 has a pair of holders 73A, 73B, and is attached to the first board base 61 via these holders 73A, 73B. The footboard 72 has a pair of holders 74A, 74B, and is attached to the second board base 62 via these holders 74A, 74B. The headboard 71 and the footboard 72 are plate-shaped and parallel to the second direction Y and the third direction Z, and both protrude upward from the floor boards 31, 32, 33, 34, 35, and 36.

In this embodiment, the first board base 61 supports the headboard 71 so that it can move between a first position Q11 shown by a solid line and a second position Q12 shown by a dashed line. The second position Q12 is farther from the first end E1 than the first position Q11.

In this embodiment, the second board base 62 supports the foot board 72 so that it can move between a first position Q21 shown by a solid line and a second position Q22 shown by a dashed line. The second position Q22 is farther from the second end E2 than the first position Q21.

If the positions of the headboard 71 and footboard 72 can be adjusted in this way, the size of the mattress placed on the floorboards 31, 32, 33, 34, 35, and 36 can be changed. For example, if the headboard 71 is positioned at the first position Q11 and the footboard 72 is positioned at the first position Q21, a short-sized mattress can be used. Also, if the headboard 71 is positioned at the second position Q12 and the footboard 72 is positioned at the second position Q22, a long-sized mattress can be used.

Figure 3 is a schematic side view of the bed device 1. This figure shows the side rail 9 attached to the second side rail base 4B. The side rail 9 can also be attached to the other side rail bases 4A, 4C, and 4D in the same way.

In the example of FIG. 3, the side fence 9 is lattice-shaped with multiple bars extending parallel to the first direction X or the third direction Z, and protrudes above the floor plates 31, 32, 33, 34, 35, and 36. Furthermore, the side fence 9 has a pair of legs 91 for attachment to the side fence bases 4A, 4B, 4C, and 4D.

The bed frame 2 comprises a lower frame 21, an upper frame 22, and a link 23 that connects these frames 21, 22. The lower frame 21 is provided with a number of support legs 211 for placing the bed device 1 on the floor. The upper frame 22 supports floor plates 31, 32, 33, 34, 35, and 36.

The bed device 1 further includes a drive mechanism 8 disposed below the bed plates 31, 32, 33, 34, 35, and 36. For example, the drive mechanism 8 includes a plurality of motors and a plurality of links for transmitting the power of these motors, and raises and lowers the upper frame 22 relative to the lower frame 21. Furthermore, the drive mechanism 8 deforms the bed plates 31, 32, 33, 34, 35, and 36 from a flat state to a predetermined shape as shown in FIG. 3.

Figure 4 is a schematic perspective view showing the configuration of the upper frame 22, side fence bases 4A, 4B, covers 5A, 5B, and first board base 61 near the first end E1. The upper frame 22 includes a first side rail 23A, a second side rail 23B, and a cross bar 24. The side rails 23A, 23B are hollow members and extend parallel to the first direction X. The cross bar 24 extends parallel to the second direction Y and connects the side rails 23A, 23B at the first end E1.

The side surface of the first side rail 23A corresponds to a part of the first side portion S1 of the upper frame 22. The first side fence base 4A is connected to the first side rail 23A by a pair of connecting members 25A extending parallel to the second direction Y.

The side surface of the second side rail 23B corresponds to a part of the second side portion S2 of the upper frame 22. The second side fence base 4B is connected to the second side rail 23B by a pair of connecting members 25B extending parallel to the second direction Y.

The first board base 61 comprises a first slide member 63A, a second slide member 63B, a horizontal rod 64, a first bracket 65A, and a second bracket 65B. The first slide member 63A extends parallel to the first direction X and is inserted into the first side rail 23A. The second slide member 63B extends parallel to the first direction X and is inserted into the second side rail 23B. The horizontal rod 64 extends parallel to the second direction Y and connects the slide members 63A and 63B.

The first bracket 65A is provided at the end of the first slide member 63A. The second bracket 65B is provided at the end of the second slide member 63B. These brackets 65A and 65B are connected to the holders 73A and 73B of the headboard 71. This causes the headboard 71 to be supported by the first board base 61.

The slide members 63A and 63B are slidable relative to the side rails 23A and 23B, respectively. That is, the first board base 61 supports the headboard 71 so that the distance between the first end E1 and the headboard 71 is adjustable.

The first board base 61 shown by solid lines in FIG. 4 shows a state in which the slide members 63A and 63B are stored to their maximum extent relative to the side rails 23A and 23B, respectively. At this time, the headboard 71 supported by the first board base 61 is positioned at the first position Q11.

The first board base 61 shown by the dashed line in FIG. 4 shows a state in which the slide members 63A and 63B are fully pulled out from the side rails 23A and 23B, respectively. At this time, the headboard 71 supported by the first board base 61 is positioned at the second position Q12. Hereinafter, the distance in the first direction X between the positions Q11 and Q12 is defined as L0.

The structure of the first board base 61 is not limited to the example shown in FIG. 4 as long as the position of the headboard 71 can be adjusted. The first board base 61 may be capable of adjusting the position of the headboard 71 in three or more stages.

Figure 5 is a schematic perspective view showing the state in which the covers 5A and 5B are removed from the side fence bases 4A and 4B in the structure shown in Figure 4. In this embodiment, the side fence bases 4A and 4B have a shape that is plane-symmetrical with respect to a plane parallel to the first direction X and the third direction Z.

The side fence bases 4A and 4B each have a first end 41 and a second end 42 in the first direction X, and extend a long distance between these ends 41 and 42. Furthermore, the side fence bases 4A and 4B each have an upper surface 43, a lower surface 44 opposite the upper surface 43, an outer side surface 45 connecting the upper surface 43 and the lower surface 44, and an inner side surface 46 connecting the upper surface 43 and the lower surface 44. A pair of connecting members 25A are connected to the side surface 46 of the first side fence base 4A, and a pair of connecting members 25B are connected to the side surface 46 of the second side fence base 4B.

Furthermore, the side fence bases 4A and 4B each have a pair of first support holes H1 and a pair of second support holes H2. Both support holes H1 and H2 extend parallel to the third direction Z and open to the upper surface 43 of the side fence bases 4A and 4B.

In the example of FIG. 5, a pair of one first support hole H1 and one second support hole H2 is arranged near the first end 41 of the first side fence base 4A, near the second end 42 of the first side fence base 4A, near the first end 41 of the second side fence base 4B, and near the second end 42 of the second side fence base 4B. In each pair, the support holes H1 and H2 are aligned in the first direction X. In addition, in each pair, the second support hole H2 is located closer to the first end E1 than the first support hole H1. Preferably, the distance L1 between the centers of the support holes H1 and H2 in each pair is equal to the distance L0 shown in FIG. 4.

In the second side fence base 4B shown in FIG. 5, four protrusions 47 that align with each support hole H1, H2 protrude from the underside 44 of the side fence bases 4A, 4B. The first side fence base 4A also has similar protrusions 47.

A first mark M1 and a second mark M2 are provided on the upper surface 43 of each of the side fence bases 4A and 4B, aligned in the first direction X. These marks M1 and M2 are, for example, stickers attached to the upper surface 43.

Figures 6A, 6B, 6C, and 6D are schematic front, back, top, and bottom views, respectively, of the first cover 5A. In these figures, it is assumed that the first cover 5A is in the position shown in Figure 5, and arrows are provided in the first direction X, second direction Y, and third direction Z.

As shown in Figure 5 and Figures 6A to 6D, the first cover 5A has a first end 51 and a second end 52 in the first direction X, and extends a long length between these ends 51, 52. Furthermore, the first cover 5A has a storage portion R into which the first side fence base 4A can be fitted. The storage portion R is a space surrounded by the first portion P1, the second portion P2, the third portion P3, the fourth portion P4, and the fifth portion P5.

The first part P1 covers the upper surface 43 of the first side fence base 4A. The second part P2 covers the lower surface 44 of the first side fence base 4A. The third part P3 covers the side surface 45 of the first side fence base 4A. The fourth part P4 covers the first end 41 of the first side fence base 4A. The fifth part P5 covers the second end 42 of the first side fence base 4A. In this embodiment, the first part P1 and the third part P3 are part of the outer wall of the first cover 5A, and the second part P2, the fourth part P4 and the fifth part P5 are part of a rib provided on the inside of the outer wall, but are not limited to this example.

As shown in Figures 5, 6B, and 6C, the first portion P1 has a pair of openings 53, a display window 54, and a pair of tabs 55. In this embodiment, the openings 53 and the display window 54 are notches recessed from one side of the first portion P1 in the second direction Y. However, the openings 53 and the display window 54 may be holes, for example, circular holes. Each tab 55 protrudes downward (toward the second portion P2) from one side of the first portion P1.

As shown in FIG. 6B, the display window 54 is located at a position offset from the center C0 of the storage section R in the first direction X. Specifically, the display window 54 is located between the center C0 and the second end 52.

As shown in FIG. 6C, one opening 53 is located between the center C0 and the first end 51, and the other opening 53 is located between the center C0 and the second end 52. Furthermore, the distance between the one opening 53 and the center C0 is L2, and the distance between the other opening 53 and the center C0 is L3. In the example of FIG. 6C, the distance L2 is smaller than the distance L3 (L2<L3). Preferably, the difference between the distance L2 and the distance L3 is equal to the distance L0 shown in FIG. 4.

As shown in Figures 5, 6B, and 6D, the first cover 5A has four recesses 56 located below the storage section R. These recesses 56 are formed by notches and ribs provided in the second portion P2, and as shown in Figure 6D, they also open into the outer wall below the first cover 5A. The protrusions 47 shown in Figure 5 are fitted into these recesses 56.

As shown in Figures 5 and 6B, the second part P2 has a pair of claws 57. These claws 57 protrude upward (toward the first part P1) from one side of the second part P2 and are aligned in the third direction Z with the claws 55 of the first part P1.

When the first side fence base 4A is fitted into the storage section R, each claw 55 engages with the corner formed by the upper surface 43 and the side surface 46, and each claw 57 engages with the corner formed by the lower surface 44 and the side surface 46. Furthermore, each protrusion 47 of the first side fence base 4A fits into the recess 56 of the first cover 5A.

As shown in Figures 6A and 6C, a pair of slits 58 are provided at the corner formed by the first portion P1 and the third portion P3. Furthermore, as shown in Figures 5, 6A, and 6C, a pair of slits 59 are provided at the corner formed by the second portion P2 and the third portion P3.

Each slit 58 is aligned with a claw 55 in the second direction Y. Also, each slit 59 is aligned with a claw 57 in the second direction Y. By providing such slits 58, 59, the portion of the first part P1 near the claw 55 and the portion of the second part P2 near the claw 57 are more likely to deform when attaching or detaching the first cover 5A and the first side fence base 4A. This makes it easier to attach and detach the first cover 5A to and from the first side fence base 4A.

The second cover 5B shown in Figures 4 and 5 has a shape that is plane-symmetrical to the first cover 5A with respect to a plane parallel to the first direction X and the third direction Z. The structures of the portion of the upper frame 22 near the second end E2, the second board base 62, the side fence bases 4C and 4D, and the covers 5C and 5D are similar to the structures of the portion of the upper frame 22 near the first end E1, the first board base 61, the side fence bases 4A and 4B, and the covers 5A and 5B, respectively. For example, the side fence bases 4C and 4D and the covers 5C and 5D have a shape that is plane-symmetrical to the side fence bases 4A and 4B and the covers 5A and 5B with respect to a plane parallel to the second direction Y and the third direction Z.

In this embodiment, covers 5A and 5D have the same shape, and covers 5B and 5C have the same shape. Furthermore, covers 5A, 5B, 5C, and 5D can be attached to any of side fence bases 4A, 4B, 4C, and 4D, respectively.

Figure 7 is a schematic plan view showing the relationship between the side fence bases 4A, 4B and the covers 5A, 5B. When the first cover 5A is attached to the first side fence base 4A, the first ends 41, 51 are positioned on the same side, and the second ends 42, 52 are positioned on the same side. When the first cover 5A is attached to the first side fence base 4A with the first ends 41, 51 positioned in this way, the two first support holes H1 of the first side fence base 4A are exposed through the two openings 53 of the first cover 5A, respectively, and the two second support holes H2 of the first side fence base 4A are blocked by the first part P1 of the first cover 5A. Furthermore, the first mark M1 of the first side fence base 4A is exposed through the display window 54 of the first cover 5A, and the second mark M2 of the first side fence base 4A is covered by the first part P1 of the first cover 5A. In this state, the side fence 9 can be attached to the first side fence base 4A by inserting each leg 91 of the side fence 9 into the first support hole H1.

When the second cover 5B is attached to the second side fence base 4B, the first ends 41 and 51 are positioned on the same side, and the second ends 42 and 52 are positioned on the same side. When the second cover 5B is attached to the second side fence base 4B after positioning in this way, the two first support holes H1 of the second side fence base 4B are exposed through the two openings 53 of the second cover 5B, and the two second support holes H2 of the second side fence base 4B are blocked by the first part P1 of the second cover 5B. Furthermore, the first mark M1 of the second side fence base 4B is exposed through the display window 54 of the second cover 5B, and the second mark M2 of the second side fence base 4B is covered by the first part P1 of the second cover 5B. In this state, the side fence 9 can be attached to the second side fence base 4B by inserting each leg 91 of the side fence 9 into the first support hole H1.

On the other hand, when the second cover 5B is attached to the first side fence base 4A, the first end 41 and the second end 52 are positioned on the same side, and the second end 42 and the first end 51 are positioned on the same side. When the second cover 5B is attached to the first side fence base 4A with this positioning, the two second support holes H2 of the first side fence base 4A are exposed through the two openings 53 of the second cover 5B, respectively, and the two first support holes H1 of the first side fence base 4A are blocked by the first part P1 of the second cover 5B. Furthermore, the second mark M2 of the first side fence base 4A is exposed through the display window 54 of the second cover 5B, and the first mark M1 of the first side fence base 4A is covered by the first part P1 of the second cover 5B. In this state, the side fence 9 can be attached to the first side fence base 4A by inserting each leg 91 of the side fence 9 into the second support hole H2.

When the first cover 5A is attached to the second side fence base 4B, the first end 41 and the second end 52 are positioned on the same side, and the second end 42 and the first end 51 are positioned on the same side. When the first cover 5A is attached to the second side fence base 4B with this positioning, the two second support holes H2 of the second side fence base 4B are exposed through the two openings 53 of the first cover 5A, respectively, and the two first support holes H1 of the second side fence base 4B are blocked by the first part P1 of the first cover 5A. Furthermore, the second mark M2 of the second side fence base 4B is exposed through the display window 54 of the first cover 5A, and the first mark M1 of the second side fence base 4B is covered by the first part P1 of the first cover 5A. In this state, the side fence 9 can be attached to the second side fence base 4B by inserting each leg 91 of the side fence 9 into the second support hole H2.

For example, when the first cover 5A is attached to the first side fence base 4A and the second cover 5B is attached to the second side fence base 4B, and when the second cover 5B is attached to the first side fence base 4A and the first cover 5A is attached to the second side fence base 4B, the positions of the centers C0 of the covers 5A and 5B in the first direction X are the same. Furthermore, in both cases, the center C0 is located between the marks M1 and M2.

In the example of FIG. 7, the first mark M1 on the side fence bases 4A and 4B is marked with the letter "S" which is the initial letter of "Short," and the second mark M2 on the side fence bases 4A and 4B is marked with the letter "L" which is the initial letter of "Long." However, the marks M1 and M2 are not limited to this example.

Figure 8 is a schematic plan view showing a first mounting mode of covers 5A and 5B to side fence bases 4A and 4B. Figure 9 is a schematic plan view showing a second mounting mode of covers 5A and 5B to side fence bases 4A and 4B.

In the example of Figure 8, a first cover 5A is attached to the first side fence base 4A, and a second cover 5B is attached to the second side fence base 4B. Furthermore, the headboard 71 is positioned at the first position Q11.

In the example of Figure 9, the second cover 5B is attached to the first side fence base 4A, and the first cover 5A is attached to the second side fence base 4B. Furthermore, the headboard 71 is positioned at the second position Q12.

In the state shown in FIG. 8, a pair of side fences 9 are attached using the first support holes H1 of the side fence bases 4A and 4B. In the state shown in FIG. 9, a pair of side fences 9 are attached using the second support holes H2 of the side fence bases 4A and 4B.

In both Figures 8 and 9, a gap G is formed between the headboard 71 and each side fence 9. If the distance L1 between the centers of the support holes H1 and H2 shown in Figure 5 is equivalent to the distance L0 between the positions Q11 and Q12 shown in Figure 4, then the gap G shown in Figure 8 and the gap G shown in Figure 9 are substantially equivalent.

In the state shown in FIG. 8, the first mark M1 appears through the display window 54 of each of the covers 5A and 5B. In the state shown in FIG. 9, the second mark M2 appears through the display window 54 of each of the covers 5A and 5B.

Note that while Figures 7 to 9 focus on the side fence bases 4A, 4B and covers 5A, 5B, the side fence bases 4C, 4D and covers 5C, 5D can also be similarly attached and detached. That is, when the third cover 5C is attached to the third side fence base 4C and the fourth cover 5D is attached to the fourth side fence base 4D, the first support hole H1 of the side fence bases 4C, 4D is exposed through the opening 53 of the covers 5C, 5D. Also, when the fourth cover 5D is attached to the third side fence base 4C and the third cover 5C is attached to the fourth side fence base 4D, the second support hole H2 of the side fence bases 4C, 4D is exposed through the opening 53 of the covers 5C, 5D.

When the side fence 9 is attached using the first support hole H1 of the side fence base 4C, 4D and the footboard 72 is positioned at the first position Q21 (see FIG. 2), a gap G is formed between the footboard 72 and each side fence 9. Also, when the side fence 9 is attached using the second support hole H2 of the side fence base 4C, 4D and the footboard 72 is positioned at the second position Q22 (see FIG. 2), a gap G is formed between the footboard 72 and each side fence 9. For example, the gap G in each of these two attachment methods is substantially the same.

According to the present embodiment described above, it is possible to provide a bed apparatus 1 with improved convenience.
For example, the covers 5A, 5B, 5C, and 5D disclosed in this embodiment have a first part P1, a second part P2, and a third part P3 that respectively cover the upper surface 43, the lower surface 44, and the side surface 45 of the side rail bases 4A, 4B, 4C, and 4D. With this configuration, it is possible to prevent the surfaces 43, 44, and 45 of the metal side rail bases 4A, 4B, 4C, and 4D from directly hitting objects around the bed apparatus 1, the user, etc.

In addition, because covers 5A, 5B, 5C, and 5D have a first portion P1 and a second portion P2, a mounting structure that is resistant to impacts in the third direction Z can be realized. This makes it possible to prevent covers 5A, 5B, 5C, and 5D from unintentionally coming off even if covers 5A, 5B, 5C, and 5D are subjected to an external force in the third direction Z, for example.

In addition, the first portion P1 has an opening 53 that exposes the first support hole H1 or the second support hole H2, so that the covers 5A, 5B, 5C, and 5D do not prevent the side fence 9 from being attached to the side fence bases 4A, 4B, 4C, and 4D.

When the covers 5A, 5B, 5C, and 5D are attached, one of the support holes H1 and H2 in the side fence bases 4A, 4B, 4C, and 4D overlaps with the opening 53, and the other is blocked by the first portion P1. This makes it easy to determine which support hole should be used to attach the side fence 9.

For example, if you want to change the support holes used to attach the side fence 9 to the side fence bases 4A and 4B, you can simply switch the covers attached to the side fence bases 4A and 4B between covers 5A and 5B. The same applies to side fence bases 4C and 4D and covers 5C and 5D. With this configuration, there is no need to prepare two types of covers corresponding to the support holes H1 and H2 for each of the side fence bases 4A, 4B, 4C, and 4D.

Furthermore, in this embodiment, the positions of the headboard 71 and footboard 72 can be adjusted. In this configuration, the support holes used to attach the side fence 9 can be changed by replacing the cover, so that the attachment mode of the side fence 9 can be realized to suit the positions of the headboard 71 and footboard 72. Also, by looking at the first mark M1 or the second mark M2 that appears in the display window 54, the attachment mode of the covers 5A, 5B to the side fence bases 4A, 4B can be easily understood.

8, if the headboard 71 is moved to the second position Q12 while leaving the side fences 9 in their original positions, the gap G will increase. If the gap G becomes too large, a part of the user's body or the mattress may easily become caught in the gap G. In response to this, by replacing the covers 5A, 5B as the headboard 71 moves and shifting the holes for attaching the side fences 9 between the support holes H1, H2, it is possible to prevent the gap G from expanding.
In addition to the above, various other advantageous effects can be obtained from this embodiment.

[Second embodiment]
A second embodiment will now be described. The same configuration as in the first embodiment can be applied to parts not specifically mentioned.

Figure 10 is a schematic plan view showing a portion of the bed apparatus 1 according to the second embodiment. In this figure, the first side rail 23A, the second side rail 23B, the cross bar 24, the first side rail base 4A, the second side rail base 4B, the first cover 5A and the second cover 5B are shown, and other elements are omitted.

A pair of first brackets 26a, 26b are provided on the first side rail 23A (first side portion S1) with a gap in the first direction X. The first bracket 26a is located closer to the first end E1 than the first bracket 26b.

Similarly, a pair of second brackets 26c, 26d are provided on the second side rail 23B (second side portion S2) with a gap therebetween in the first direction X. The second bracket 26c is located closer to the first end E1 than the second bracket 26d. The first bracket 26a and the second bracket 26c are aligned in the second direction Y. The first bracket 26b and the second bracket 26d are aligned in the second direction Y.

In this embodiment, the first side fence base 4A includes a pair of holders 48a, 48b and a connecting member 49 that connects the holders 48a, 48b. The holders 48a, 48b each have an attachment portion 101 and an extension portion 102 that extends from the attachment portion 101.

The mounting parts 101 of the retainers 48a and 48b can be connected to the first brackets 26a and 26b, respectively. This connection method is not particularly limited, but in one example, fastening with screws or bolts can be used. In the example of FIG. 10, the extension parts 102 of the retainers 48a and 48b each extend from the mounting part 101 in parallel with the first direction X toward the bottom in the figure (the direction toward the second end E2 shown in FIG. 2, etc.). Furthermore, each of these extension parts 102 has one support hole H into which the leg part 91 of the side fence 9 described above can be inserted.

The first cover 5A has a shape that allows the retainers 48a, 48b to be fitted into it. Furthermore, the first cover 5A has a pair of openings 53. In the example of FIG. 10, the openings 53 are circular holes, but may be cutouts similar to those in the first embodiment. When the retainers 48a, 48b are fitted into the first cover 5A, the first cover 5A covers the upper, lower and outer side surfaces of the retainers 48a, 48b. At this time, the support holes H of the retainers 48a, 48b are exposed through the openings 53.

The second side fence base 4B has a shape that is symmetrical to the first side fence base 4A with respect to a plane parallel to the first direction X and the third direction Z. That is, like the first side fence base 4A, the second side fence base 4B has a pair of holders 48c, 48d and a connecting member 49 that connects these holders 48c, 48d. The holders 48c, 48d have an attachment portion 101 and an extension portion 102 that extends from the attachment portion 101.

The mounting parts 101 of the holders 48c, 48d can be connected to the second brackets 26c, 26d, respectively. This connection method is the same as the connection method between the holders 48a, 48b and the first brackets 26a, 26b. In the example of FIG. 10, the extension parts 102 of the holders 48c, 48d each extend from the mounting part 101 in parallel with the first direction X toward the bottom in the figure (the direction toward the second end E2 shown in FIG. 2, etc.). Furthermore, each of these extension parts 102 has one support hole H.

The second cover 5B has a shape that allows the retainers 48c, 48d to be fitted into it. Furthermore, the second cover 5B has a pair of openings 53, similar to the first cover 5A. When the retainers 48c, 48d are fitted into the second cover 5B, the second cover 5B covers the upper, lower and outer side surfaces of the retainers 48c, 48d. At this time, the support holes H of the retainers 48c, 48d are exposed through the openings 53.

10, the support hole H of the retainer 48a is located below the connection position Qa between the first bracket 26a and the mounting portion 101 (in the direction toward the second end E2 shown in FIG. 2, etc.), the support hole H of the retainer 48b is located below the connection position Qb between the mounting portion 101 and the first bracket 26a, the support hole H of the retainer 48c is located below the connection position Qc between the mounting portion 101 and the second bracket 26c, and the support hole H of the retainer 48d is located below the connection position Qd between the mounting portion 101 and the second bracket 26d. For example, the connection positions Qa, Qb, Qc, and Qd correspond to the centers of the brackets 26a, 26b, 26c, and 26d in the first direction X, respectively. As another example, the connection positions Qa, Qb, Qc, and Qd correspond to the centers in the first direction X of the mounting portion 101 that is connected to the brackets 26a, 26b, 26c, and 26d, respectively.

In the example of FIG. 10, the distance between the connection position Qa and the center of the support hole H of the holder 48a, the distance between the connection position Qb and the center of the support hole H of the holder 48b, the distance between the connection position Qc and the center of the support hole H of the holder 48c, and the distance between the connection position Qd and the center of the support hole H of the holder 48d are all L4.

The first side rail base 4A can also be attached to the second side rail 23B via the second brackets 26c and 26d. The second side rail base 4B can also be attached to the first side rail 23A via the first brackets 26a and 26b.

Figure 11 is a schematic plan view showing a first mounting mode of the side rail bases 4A and 4B to the side rails 23A and 23B. Figure 12 is a schematic plan view showing a second mounting mode of the side rail bases 4A and 4B to the side rails 23A and 23B.

In the example of Figure 11, similar to the example of Figure 10, the first side rail base 4A is attached to the first side rail 23A via first brackets 26a and 26b, and the second side rail base 4B is attached to the second side rail 23B via second brackets 26c and 26d.

On the other hand, in the example of FIG. 12, the first side rail base 4A is attached to the second side rail 23B via the second brackets 26c and 26d, and the second side rail base 4B is attached to the first side rail 23A via the first brackets 26a and 26b. Specifically, the retainer 48a is connected to the second bracket 26d, the retainer 48b is connected to the second bracket 26c, the retainer 48c is connected to the first bracket 26b, and the retainer part 48d is connected to the first bracket 26a.

In both Figures 11 and 12, a first cover 5A is attached to the first side fence base 4A, and a second cover 5B is attached to the second side fence base 4B. However, the second cover 5B may be attached to the first side fence base 4A, and the first cover 5A may be attached to the second side fence base 4B.

In Figures 11 and 12, the side fences 9 attached to the side fence bases 4A and 4B, respectively, are shown with dashed lines. In this embodiment, as described using Figure 10, the connection positions Qa, Qb, Qc, and Qd and the support holes H are separated by a distance L4 in the first direction X. As a result, the positions of each support hole H in the first direction X are different in Figures 11 and 12. As a result, the positions of each side fence 9 in the first direction X are different in Figures 11 and 12.

Specifically, compared to each side fence 9 in the example of FIG. 11, each side fence 9 in the example of FIG. 12 has been moved toward the first end E1 by a distance equivalent to twice the distance L4. In this way, even with the configuration of this embodiment, it is possible to adjust the position of the side fence 9 in the same way as in the first embodiment.

For example, the first mounting manner shown in FIG. 11 may be used when the headboard 71 is in the above-mentioned position Q11, and the second mounting manner shown in FIG. 12 may be used when the headboard 71 is in the above-mentioned position Q12. This makes it possible to prevent the gap G between the headboard 71 and the side fence 9 from becoming excessively large, as in the first embodiment. Furthermore, if the distance L4 is 1/2 the distance L0 shown in FIG. 4, the gap G can be kept constant when the headboard 71 is in position Q11 and when it is in position Q12.

In this embodiment, the covers 5A and 5B may have the same shape. In this case, molds or the like for manufacturing the covers 5A and 5B are not required, and the manufacturing cost of the bed apparatus 1 can be reduced.

Note that while Figures 10 to 12 focus on side fence bases 4A, 4B and covers 5A, 5B, a similar structure can also be applied to side fence bases 4C, 4D and covers 5C, 5D.

The above embodiments do not limit the scope of the present invention to the configurations disclosed in the embodiments. The present invention can be implemented by modifying the configurations disclosed in the embodiments in various ways.

For example, the bed apparatus 1 does not need to include all of the side rail bases 4A, 4B, 4C, 4D and the covers 5A, 5B, 5C, 5D. The bed apparatus 1 may include the side rail bases 4A, 4B and the covers 5A, 5B, but not the side rail bases 4C, 4D and the covers 5C, 5D. As another example, the bed apparatus 1 may include the side rail bases 4C, 4D and the covers 5C, 5D, but not the side rail bases 4A, 4B and the covers 5A, 5B.

The first mark M1 and the second mark M2 in the first embodiment may be provided on the side surface 45 of the side fence bases 4A, 4B, 4C, and 4D, respectively. In this case, the display window 54 may be provided in the third portion P3 of the covers 5A, 5B, 5C, and 5D, respectively.

The structure of the side rail bases 4A, 4B, 4C, 4D and the covers 5A, 5B, 5C, 5D can also be applied to bed devices in which the position of the headboard 71 and footboard 72 cannot be adjusted, or in which the shape of the floor panels 31, 32, 33, 34, 35, 36 cannot be deformed.
