[0004] [Patent Document 1] Patent No. 2800916 [Patent Document 2] JP 2000-37261 A Summary of the Invention [Problem to be solved by the invention]

[0005] In a bed apparatus having an extendable bed plate as described above, if the bed plate expands or contracts due to an unintentional external force, a mismatch in shape between the mattress and the bed plate may occur.

[0006] In addition, in most cases, the mattress is simply placed on the bed base and is not fixed to the bed base, so the mattress may shift relative to the bed base due to the user's movements on the mattress or when getting on and off the mattress.

[0007] In addition, there is room for various improvements in conventional bed apparatuses. Therefore, an object of the present disclosure is to improve the usability of bed apparatuses, particularly those having extendable and contractable bed panels. [Means for solving the problem]

[0016] An embodiment will be described with reference to the drawings. In this embodiment, an electric bed capable of changing the shape of a bed platform is disclosed as an example of a bed apparatus. However, the configuration disclosed in this embodiment, particularly the structure related to the expansion and contraction of the bed platform, can also be applied to other types of bed apparatuses, such as bed apparatuses that do not have an electrical control element.

[0017] 1 is a schematic perspective view of a bed apparatus 1 according to this embodiment. In the following description, a first direction X (longitudinal direction), a second direction Y (width direction), and a third direction Z (height direction) are defined as shown in the figure. In this embodiment, these directions X, Y, and Z are perpendicular to each other.

[0018] The bed apparatus 1 includes a bed frame 2 and a bed plate body 3 arranged on the bed frame 2. Both the bed frame 2 and the bed plate body 3 have an elongated shape in a first direction X.

[0019] The bed plate body 3 has side portions S1, S2, S3, and S4. The side portions S1 and S2 extend parallel to a first direction X. The side portions S3 and S4 extend parallel to a second direction Y. For example, the side portion S3 is located on the head side of a user lying on his / her back on the bed apparatus 1, and the side portion S4 is located on the foot side of the user. In addition, the side portion S1 is located on the right side of the user, and the side portion S2 is located on the left side of the user.

[0020] The bed plate body 3 includes a back bed plate 3A, a lumbar bed plate 3B, a thigh bed plate 3C, and a foot bed plate 3D. These bed plates 3A, 3B, 3C, and 3D are arranged in order in the first direction X. Two adjacent bed plates 3A, 3B, 3C, and 3D are connected to be rotatable about an axis parallel to the second direction Y. When the bed device 1 is in use, a mattress is placed on the bed plates 3A, 3B, 3C, and 3D. The side portion S1 is formed by one end of the bed plates 3A, 3B, 3C, and 3D in the second direction Y, and the side portion S2 is formed by the other end of the bed plates 3A, 3B, 3C, and 3D in the second direction Y. The side portion S3 is formed by the head end of the bed plate 3A, and the side portion S4 is formed by the foot end of the bed plate 3D.

[0021] The bed apparatus 1 is provided with a number of covers attached to the side portions S1 and S2. In the example of Fig. 1, covers 41, 42, and 43 are attached to the side portions S1 and S2 of the back plate 3A, respectively. Similarly, covers 41, 42, and 43 are attached to the side portions S1 and S2 of the foot plate 3D, respectively.

[0022] The bed apparatus 1 includes at least one stopper 5 that can be attached to the side portions S1, S2, S3, and S4. In the example of Fig. 1, the stopper 5 is attached to each cover 41 on each of the side portions S1 and S2.

[0023] The bed apparatus 1 may include a plurality of side rail bases 6 for supporting the side rails arranged along the sides S1 and S2. In the example of Fig. 1, two side rail bases 6 are provided on each of the sides S1 and S2.

[0024] The bed apparatus 1 may include a headboard 71 and a footboard 72. In the example of Fig. 1, the headboard 71 is attached to the side portion S3 via a pair of holders 73, and the footboard 72 is attached to the side portion S4 via a pair of holders 74.

[0025] The bed apparatus 1 further includes a drive mechanism disposed below the bed plate body 3. For example, this drive mechanism includes a plurality of motors and a plurality of links for transmitting the power of these motors, and raises and lowers the bed plate body 3. Furthermore, this drive mechanism transforms the bed plate body 3 from a flat state as shown in Fig. 1 into a predetermined shape. Examples of the predetermined shape include a back-raised state in which the back plate 3A is raised, and a leg-raised state in which at least one of the thigh plate 3C and the foot plate 3D is raised.

[0026] 2 and 3 are schematic perspective views of the back floor panel 3A, the covers 41, 42, 43, and the fastener 5. Fig. 3 shows a state in which the covers 41, 43 and the fastener 5 provided on the side portion S1 have been removed.

[0027] The rear floor panel 3A includes a first floor panel 31, a second floor panel 32, and a third floor panel 33 aligned along the first direction X. The floor panels 31, 32, and 33 are formed of, for example, synthetic resin, and have a plurality of through holes that are elongated in the second direction Y.

[0028] The second bed plate 32 is located closer to the head than the first bed plate 31, and has a side portion S3. The third bed plate 33 is located closer to the feet than the first bed plate 31. A plurality of connecting portions 81 protrude from the end portion on the foot side of the third bed plate 33 for rotatably connecting the lumbar bed plate 3B shown in FIG.

[0029] The ends of the first floor plate 31 and the second floor plate 32 in the second direction Y are fitted into the covers 41 arranged on each of the side portions S1 and S2. The end of the third floor plate 33 in the second direction Y is fitted into the covers 42 arranged on each of the side portions S1 and S2. The ends of the first floor plate 31 and the third floor plate 33 in the second direction Y are fitted into the covers 43 arranged on each of the side portions S1 and S2.

[0030] The head side end of the cover 43 is located between the cover 41 and the first floor plate 31. The foot side end of the cover 43 is located between the cover 42 and the third floor plate 33. The covers 41 and 43 are not fixed to each other. This allows the cover 41 to slide relative to the cover 43 in the first direction X.

[0031] 3, the side wall 310 of the first floor board 31 in the side portion S1 is provided with slits 31L and 31S aligned in the first direction X. The slit 31L is located closer to the head side than the slit 31S. The slits 31L and 31S each have an elongated shape in the third direction Z and open at the lower end of the side wall 310.

[0032] The cover 41 has a first engagement portion EP1 that can engage with a restricting portion 53 of the stopper 5, which will be described later. In this embodiment, the first engagement portion EP1 includes a first engagement hole H1 that penetrates the cover 41 in the second direction Y.

[0033] The cover 41 has a slit 411 extending in the first direction X. Similarly, the cover 42 has a slit 421 extending in the first direction X. By providing the slits 411, 421, even if the insides of the covers 41, 42 get wet, for example, when cleaning the floor panel body 3, the insides of the covers 41, 42 can be dried.

[0034] 3, the width of the slit 411 is smaller than the diameter of the first engagement hole H1. Furthermore, the slit 411 is connected to the first engagement hole H1. As another example, the slit 411 may be an opening independent of the first engagement hole H1.

[0035] The side wall of the first floor board 31 in the side portion S2 is also provided with slits 31L, 31S similar to those in the side wall 310. The configurations of the covers 41, 42, 43 attached to the side portion S2 are similar to the configurations of the covers 41, 42, 43 attached to the side portion S1.

[0036] The bed plate body 3 is extendable and retractable in the first direction X. In order to realize such a configuration, in this embodiment, the first bed plate 31 and the second bed plate 32 are supported by the bed frame 2 so as to be relatively movable (slidable) in the first direction X, as shown by the arrow R in Fig. 2. As a result, the position of the side portion S3 changes between the position shown by the solid line and the position shown by the dashed line in Fig. 2.

[0037] 4 is a perspective view showing, in outline, the elements that support the back floorboard 3A of the bed frame 2. The bed frame 2 includes a first frame 8 and a second frame 9. As indicated by the arrow R, the second frame 9 is attached to the first frame 8 so as to be movable in a first direction X.

[0038] The first frame 8 supports a first floor plate 31 and a third floor plate 33. The second frame 9 supports a second floor plate 32. The first frame 8 and the first floor plate 31, the first frame 8 and the third floor plate 33, and the second frame 9 and the second floor plate 32 are each fixed by an appropriate means such as screws.

[0039] The first frame 8 has frame members 82, 83, and 84 extending parallel to the second direction Y, and crosspieces 85, 86, 87, and 88 connecting these frame members 82, 83, and 84. The frame member 83 is located between the frame members 82 and 84 in the first direction X. The above-mentioned connecting portion 81 is provided on the frame member 84. The crosspieces 85, 86, 87, and 88 extend parallel to the first direction X.

[0040] The first frame 8 further has a pair of second engagement portions EP2 engageable with restricting portions 53 of the stopper 5 described below. These second engagement portions EP2 are provided at both ends of the frame material 83 in the second direction Y. In this embodiment, each second engagement portion EP2 includes a plate PL that is elongated in the first direction X, and two second engagement holes H2 (H2L, H2S) that penetrate the plate PL and are aligned in the first direction X.

[0041] The second frame 9 has a frame material 91 extending parallel to the second direction Y, and a pair of rods 92 extending from the frame material 91 in the first direction X. The frame material 91 is disposed closer to the head than the frame material 82.

[0042] Each rod 92 is disposed outboard of the crosspieces 85, 86, 87, 88 in the second direction Y, and has a length greater than at least the distance between the frame members 82, 83. Each rod 92 is slidably passed through a through hole 821, 831 provided in the frame members 82, 83, respectively.

[0043] In such a configuration, the second frame 9 is movable between a position where the frame material 91 is close to the frame material 82 as shown by the solid line in Fig. 4, and a position where the frame material 91 and the frame material 82 are separated as shown by the dashed line. However, the configuration of the first frame 8 and the second frame 9 is not limited to the example shown in Fig. 4.

[0044] 5 and 6 are schematic perspective cross-sectional views of the back base plate 3A and the bed frame 2. Fig. 5 shows the back base plate 3A in a state where it is fully contracted, and Fig. 6 shows the back base plate 3A in a state where it is fully extended.

[0045] The first bed board 31 has a wall portion 311 on the head side, a recessed portion 312 extending in the second direction Y, and a flat surface 313 (upper surface) in the vicinity of the wall portion 311. The frame material 82 of the first frame 8 is disposed so as to cover the wall portion 311. The frame material 83 of the first frame 8 is disposed in the recessed portion 312.

[0046] The second floor plate 32 has a plate portion 321 and a pair of walls 322, 323 protruding downward from the plate portion 321. The wall portion 322 is provided at the head side end of the plate portion 321. The wall portion 323 faces the wall portion 322 with a gap therebetween. The frame material 91 of the second frame 9 is located between the walls 322, 323.

[0047] 5, when the rear floor board 3A is in the maximally contracted state, the wall portion 323 is in contact with the frame material 82. Furthermore, the plate portion 321 covers the entire flat surface 313.

[0048] 6, when the back floor board 3A is in the maximally extended state, the wall portion 323 is separated from the frame material 82. Furthermore, most of the flat surface 313 is exposed from the plate portion 321.

[0049] When the second floor plate 32 moves relative to the first floor plate 31 between the position in Fig. 5 and the position in Fig. 6, the plate portion 321 slides on the flat surface 313. The cover 41 is fixed to at least one of the second floor plate 32 and the second frame 9. On the other hand, the cover 41 is not fixed to the first floor plate 31 and the first frame 8. Therefore, when the second floor plate 32 moves, the cover 41 moves together with the second floor plate 32 while sliding on the outer surface of the cover 43.

[0050] 6, even when the back panel 3A is fully extended, a part of the cover 41 overlaps with the cover 43. This prevents a gap from being generated between the covers 41 and 43, and improves the safety of the bed apparatus 1.

[0051] 7 and 8 are schematic perspective views of the fastener 5. The fastener 5 has a holder portion 51 for attaching the fastener 5 to the cover 41, a mattress receiving portion 52 for preventing the mattress placed on the bed plate body 3 from shifting, and a restricting portion 53 for restricting the relative movement of the first bed plate 31 and the second bed plate 32.

[0052] The holder portion 51 includes holding plates 511, 512 facing each other, and a connection portion 513 connecting these holding plates 511, 512. The mattress receiving portion 52 extends from the holding plate 511 in the opposite direction to the connection portion 513. In the example of Figure 7, the mattress receiving portion 52 has a pair of arc-shaped openings 521.

[0053] For example, the mattress receiving portion 52 is a flat plate that is generally perpendicular to the retaining plate 511. A pair of ribs 54 is provided at the corner formed by the retaining plate 511 and the mattress receiving portion 52. A similar rib 54 is also provided at the corner formed by the retaining plate 511 and the connecting portion 513.

[0054] In this embodiment, the restricting portion 53 includes a cylindrical pin 530. The pin 530 is made of, for example, a metal material. As shown in Fig. 7, the pin 530 has an annular groove 531 on its outer circumferential surface.

[0055] Pin 530 is located between retaining plates 511, 512, and extends from connecting portion 513. For example, the parts of fastener 5 other than pin 530 are made of synthetic resin. One end of pin 530 is provided with a head portion with an expanded diameter, and this head portion is embedded in connecting portion 513. As a result, a part of connecting portion 513 is raised as shown in FIG.

[0056] Fig. 9 is a schematic perspective view of the vicinity of side S1 from below with cover 41 and fastener 5 removed. Fig. 10 is a schematic plan view of the vicinity of side S1 from below with cover 41 and fastener 5 attached.

[0057] 9, the plate PL of the second engagement part EP2 faces the inner surface of the side wall 310 of the first floor board 31. The second engagement hole H2L overlaps with the slit 31L of the side wall 310 in the second direction Y. The second engagement hole H2S overlaps with the slit 31S of the side wall 310 in the second direction Y.

[0058] 3 is positioned between the holding plates 511 and 512, the stopper 5 is attached to the cover 41. In the state where the stopper 5 is attached to the cover 41, the holding plates 511 and 512 hold the cover 41 by the elastic force of the connection portion 513.

[0059] When the fastener 5 is attached to the cover 41, the regulating portion 53 engages with the first engagement portion EP1 and the second engagement portion EP2, thereby regulating the relative movement of the first floor plate 31 and the second floor plate 32 in the first direction X.

[0060] Specifically, the pin 530 is inserted into the first engagement hole H1 (first engagement portion EP1) of the cover 41 shown in FIG. 3. Furthermore, the pin 530 is inserted into one of the slit 31L and the second engagement hole H2L, or the slit 31S and the second engagement hole H2S, whichever overlaps with the first engagement hole H1. This prevents the cover 41 from moving in the first direction X relative to the first frame 8 on which the second engagement portion EP2 is provided. As a result, movement of the second floor plate 32 and the second frame 9 fixed to the cover 41 relative to the first floor plate 31 fixed to the first frame 8 is restricted.

[0061] 10, pin 530 is inserted into slit 31S and second engagement hole H2S. Groove 531 of pin 530 is engaged with slit 31S. That is, the width of slit 31S in first direction X is smaller than the diameter of the portion of pin 530 excluding groove 531, and the edge of slit 31S is located inside groove 531.

[0062] The side wall 310 in which the slit 31S is provided is made of, for example, synthetic resin and has flexibility. Therefore, when the pin 530 is inserted into the slit 31S, the slit 31S is pushed open by the portion of the pin 530 on the tip side of the groove 531, and the pin 530 can be inserted until the slit 31S and the groove 531 are aligned. When the fastener 5 is removed, the slit 31S is pushed open by pulling the fastener 5 with a certain amount of force or more, and the engagement between the slit 31S and the groove 531 is released.

[0063] In this manner, the slit 31S and the groove 531 are engaged with each other, thereby preventing the pin 530 from coming off unintentionally. As a result, the stopper 5 can be prevented from coming off unintentionally. The configuration of the slit 31L is the same as that of the slit 31S. Therefore, when the pin 530 is inserted into the slit 31L and the second engagement hole H2L, the edge of the slit 31L enters the inside of the groove 531, preventing the pin 530 from coming off.

[0064] 11 is a diagram showing the positional relationship between the first engagement hole H1, the second engagement holes H2L and H2S, and the slits 31L and 31S. As described above, the second engagement hole H2S and the slit 31S overlap in the second direction Y, and the second engagement hole H2L and the slit 31L overlap in the second direction Y.

[0065] As the second floor plate 32 moves, the first engagement hole H1 moves within a range including a position P1 where the first engagement hole H1 overlaps with the second engagement hole H2S and the slit 31S, and a position P2 where the first engagement hole H1 overlaps with the second engagement hole H2L and the slit 31L.

[0066] When the first engagement hole H1 is at position P1, and the fastener 5 is attached so that the pin 530 passes through the first engagement hole H1, the second engagement hole H2S and the slit 31S, the first floor panel 31 and the second floor panel 32 are fixed in place with the rear floor panel 3A contracted to its maximum extent.

[0067] On the other hand, when the first engagement hole H1 is at position P2, if the fastener 5 is attached so that the pin 530 passes through the first engagement hole H1, the second engagement hole H2L and the slit 31L, the first floor panel 31 and the second floor panel 32 are fixed in a state in which the rear floor panel 3A is fully extended.

[0068] The distance D between positions P1 and P2 corresponds to the adjustable amount of the length of the back plate 3A in the first direction X. The foot plate 3D and its surrounding structure shown in Fig. 1 are similar to the back plate 3A and its surrounding structure described using Figs. 2 to 11. That is, the length of the foot plate 3D in the first direction X can also be adjusted by an amount corresponding to the distance D. However, the adjustment amounts of the length of the back plate 3A and the foot plate 3D may be different.

[0069] The pair of holders 73 shown in Fig. 1 are connected to the second frame 9. Therefore, the position of the headboard 71 changes with the expansion and contraction of the backboard 3A. Similarly, the pair of holders 74 shown in Fig. 1 are connected to a frame (corresponding to the second frame 9) that supports the footboard 3D, and the position of the footboard 72 changes with the expansion and contraction of the footboard 3D.

[0070] In the bed apparatus 1 according to the present embodiment described above, the length of the bed plate body 3 is adjustable, making it possible to use a mattress of a size that suits the physique of the user. Furthermore, in this embodiment, the length of the bed plate body 3 can be fixed before and after expansion and contraction by the fasteners 5. This prevents the bed plate body 3 from expanding or contracting even if an unintended external force is applied to the bed plate body 3 when the bed apparatus 1 is used, and prevents the shape of the mattress from becoming inconsistent with that of the bed plate body 3.

[0071] Moreover, in this embodiment, the fastener 5 has a mattress receiving portion 52. When the fastener 5 is attached, the mattress receiving portion 52 protrudes above the bed plate body 3 as shown in Figures 5 and 6. When a mattress is placed on the bed plate body 3, the mattress receiving portion 52 comes into contact with the side of the mattress. This makes it possible to suppress displacement of the mattress in the second direction Y.

[0072] In this way, the fastener 5 according to this embodiment serves to restrict the expansion and contraction of the bed plate body 3 and to prevent the mattress from shifting. By realizing these roles with one fastener 5, the number of parts of the bed apparatus 1 is reduced and the usability of the bed apparatus 1 is further improved compared to when each role is realized by a separate part.

[0073] The scope of the present invention is not limited to the configurations disclosed in the above-described embodiments. The present invention can be implemented by modifying the configurations disclosed in the embodiments in various ways.

[0074] For example, in the present embodiment, the case where both the back plate 3A and the foot plate 3D are extendable and contractible has been exemplified, but as another example, only one of the back plate 3A and the foot plate 3D may be extendable and contractible.

[0075] In the present embodiment, the bed apparatus 1 is illustrated as including the headboard 71 and the footboard 72. As another example, the bed apparatus 1 may not include at least one of the headboard 71 and the footboard 72. In this case, the stopper 5 may be attached to the side portion S3 and the side portion S4 of the bed plate body 3, and the stopper 5 may suppress the mattress from shifting in the first direction X.

[0076] In this embodiment, the second engagement portion EP2 includes two second engagement holes H2L and H2S. As another example, the second engagement portion EP2 may include three or more second engagement holes. In this case, the length of the back floor plate 3A and the foot floor plate 3D can be adjusted in three or more stages.

[0077] In addition, the first engagement portion EP1 may have a plurality of first engagement holes H1 aligned in the first direction X, and the second engagement portion EP2 may have one second engagement hole H2 that sequentially overlaps with each of the first engagement holes H1 as the second floor plate 32 moves.
