[0004] [Patent Document 1] Patent No. 2868119 Summary of the Invention [Problem to be solved by the invention]

[0005] Even with the board locking mechanism for the bed disclosed in Patent Document 1, there is still room for improvement in various aspects of the bed apparatus. The assembly and disassembly of the bed apparatus requires a lot of time and effort. For example, there is a demand for easier attachment and detachment of the board member to and from the bed frame.

[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a bed apparatus that allows efficient attachment and detachment of a board member to and from a bed frame. [Means for solving the problem]

[0007] A bed device according to one embodiment comprises a bed frame that is long in the longitudinal direction, a board member that is detachably attached to one longitudinal end of the bed frame, a first mounting member that is provided at the one longitudinal end of the bed frame, a second mounting member that is provided on the board member and attached to the first mounting member, a lever member that is provided on one of the bed frame and the board member and has a through hole, a protruding member that is provided on the other of the bed frame and the board member where the lever member is not provided and protrudes toward the lever member, and a support mechanism that supports the lever member so that, when the second mounting member is attached to the first mounting member, the protruding member is passed through the through hole and the board member is locked to the bed frame, and a second position where the through hole is separated from the protruding member and the board member is unlocked from the bed frame.

[0008] The support mechanism may include an elastic member that biases the lever member toward the first position.

[0009] The second mounting member may be attached to the first mounting member by sliding it vertically, and when the second mounting member is slid relative to the first mounting member from a state in which the second mounting member is not attached to the first mounting member, the lever member may be displaced from the first position toward the second position as the protruding member comes into contact with the lever member, and when the second mounting member is attached to the first mounting member, the lever member may be displaced to the first position, locking the board member to the bed frame.

[0010] The lever member may be supported by the support mechanism so as to be rotatable between the first position and the second position about a rotation axis extending in a direction intersecting the vertical direction.

[0011] The lever member may be located above the through hole and may further have a tapered portion that slopes so that the distance between the bed frame and the other of the board members on which the lever member is not provided increases as the lever member approaches the upper end of the lever member.

[0012] When the second mounting member is slid relative to the first mounting member from a state in which the second mounting member is not attached to the first mounting member, the lever member may be displaced from the first position toward the second position by the protruding member coming into contact with the tapered portion.

[0013] The support mechanism may further include a holding member provided on the lever member, which may hold the lever member to the other of the bed frame and the board member that does not have the protruding member when the lever member is in the second position. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide a bed apparatus that allows the work of attaching and detaching a board member to and from a bed frame to be performed efficiently. [Brief explanation of the drawings]

[0016] An embodiment will be described with reference to the drawings. In this embodiment, an electric bed capable of raising, lowering, and deforming a bed platform is disclosed as an example of a bed apparatus. However, the configuration disclosed in this embodiment, particularly the structure relating to the connection between various members, can also be applied to other types of bed apparatus, such as a bed apparatus that does not have an electrical control element.

[0017] FIG. 1 is a schematic perspective view of a bed apparatus 1 according to this embodiment. FIG. 2 is a schematic perspective view showing a part of the bed frame 2 shown in FIG. 1. In the following description, a longitudinal direction X, a width direction Y, and a vertical direction Z are defined as shown in the figure. In this embodiment, these directions X, Y, and Z are perpendicular to one another. In this embodiment, the vertical direction Z is defined as up or upward, and the direction opposite to the vertical direction Z is defined as down or downward.

[0018] As shown in Fig. 1, the bed apparatus 1 includes a bed frame 2, a bed plate body 10 placed on the bed frame 2, and a plurality of leg members 3 attached to the bed frame 2. Both the bed frame 2 and the bed plate body 10 have an elongated shape in the longitudinal direction X.

[0019] The bed frame 2 includes a lower frame 201 and an upper frame 202 aligned in the vertical direction Z. The lower frame 201 and the upper frame 202 each have an elongated shape in the longitudinal direction X.

[0020] The bed plate body 10 includes a back plate 10A, a lumbar plate 10B, a thigh plate 10C, and a foot plate 10D. The back plate 10A, the lumbar plate 10B, the thigh plate 10C, and the foot plate 10D are arranged in this order in the longitudinal direction X. Adjacent two of these plates 10A, 10B, 10C, and 10D are connected to be rotatable about an axis parallel to the width direction Y. When the bed apparatus 1 is in use, a mattress is placed on the bed plate body 10.

[0021] The bed apparatus 1 further includes a drive mechanism (not shown) disposed below the bed plate body 10. The drive mechanism includes, for example, a plurality of motors and a plurality of links for transmitting the power of these motors, and raises and lowers the bed plate body 10. The drive mechanism includes, for example, an elevation mechanism for moving the upper frame 202 relative to the lower frame 201 along the vertical direction Z.

[0022] Furthermore, the drive mechanism deforms the bed plate body 10 from a flat state as shown in Fig. 1 to a predetermined shape. Examples of the predetermined shape include a back-raised state in which the back plate 10A is raised, and a leg-raised state in which at least one of the thigh plate 10C and the foot plate 10D is raised.

[0023] As shown in Fig. 1, the bed apparatus 1 further includes a headboard 4 and a footboard 5. The headboard 4 and the footboard 5 correspond to board members. The headboard 4 is disposed at the head-side end of the bed frame 2 in the longitudinal direction X. The footboard 5 is disposed at the leg-side end of the bed frame 2 in the longitudinal direction X.

[0024] 2, the bed frame 2 further includes, for example, a head frame 6 and an extension frame 7. The head frame 6 and the extension frame 7 are located closer to the head in the longitudinal direction X than the upper frame 202.

[0025] The head frame 6 supports a back bed plate 10A (shown in FIG. 1) of the bed plate body 10. The extension frame 7 adjusts the length of the bed frame 2 in the longitudinal direction X according to the position of the head frame 6 in the longitudinal direction X.

[0026] The extension frame 7 includes frame members 71, 72 and a cross beam 73. The frame members 71, 72 extend in the longitudinal direction X and are aligned in the width direction Y. The cross beam 73 connects the frame members 71, 72. The cross beam 73 extends linearly in the width direction Y.

[0027] The bed frame 2 also has an extension frame 8 (shown in FIG. 4) on the footboard 5 side. The extension frame 8 is configured, for example, in the same manner as the extension frame 7. That is, the extension frame 8 includes frame members 71 and 72 and a crosspiece 73.

[0028] 3 and 4 are schematic perspective views showing a part of the bed apparatus 1 according to this embodiment. Fig. 3 shows the headboard 4 and its surroundings in the bed apparatus 1. Fig. 4 shows the footboard 5 and its surroundings in the bed apparatus 1.

[0029] 3, the headboard 4 is attached to one end of the extension frame 7 in the longitudinal direction X. One end of the extension frame 7 in the longitudinal direction X corresponds to one end of the bed frame 2 in the longitudinal direction X.

[0030] The headboard 4 is detachably attached to, for example, the extension frame 7 of the bed frame 2. The footboard 5 is attached to one end of the extension frame 8 in the longitudinal direction X, as shown in Figure 4. The footboard 5 is detachably attached to, for example, the extension frame 8.

[0031] More specifically, the headboard 4 is attached to the extension frame 7 via two attachment mechanisms 100 aligned in the width direction Y. Similarly, the footboard 5 is attached to the extension frame 8 via two attachment mechanisms 100 aligned in the width direction Y.

[0032] The following mainly describes the attachment mechanism 100 located on the headboard 4 side. Fig. 5 is a schematic perspective view of the attachment mechanism 100 according to this embodiment. Fig. 6 is a schematic perspective view showing a portion of the attachment mechanism 100 according to this embodiment. Fig. 7 is a schematic front view showing a portion of the attachment mechanism 100 according to this embodiment. Fig. 8 is a schematic side view showing a portion of the attachment mechanism 100 according to this embodiment. Fig. 9 is a schematic perspective view showing a portion of the attachment mechanism 100 according to this embodiment. Figs. 5 to 9 show the vicinity of the end of the frame member 71 of the extension frame 7 on the headboard 4 side. Fig. 8 shows a portion in cross section.

[0033] 5, the bed apparatus 1 further includes a first attachment member 20, a second attachment member 30, a fixing plate 40, a lever member 50, a support mechanism 60, and a pin 70. The pin 70 is an example of a protruding member.

[0034] The attachment mechanism 100 is made up of, for example, a first attachment member 20, a second attachment member 30, a fixing plate 40, a lever member 50, a support mechanism 60, and a pin 70, but may also include other elements.

[0035] As shown in Fig. 3, the two first attachment members 20 are arranged side by side in the width direction Y with respect to the bed frame 2. As shown in Figs. 6 to 8, the first attachment members 20 are provided at one end of the frame material 71 in the longitudinal direction X. The first attachment members 20 are formed, for example, from a metal material, but may also be formed from other materials such as a resin material.

[0036] The first mounting member 20 is formed of a plate material. When viewed in the direction opposite to the longitudinal direction X, the first mounting member 20 has a generally rectangular shape. The first mounting member 20 extends elongatedly in the vertical direction Z, for example. The first mounting member 20 has a first portion 21 connected to the frame material 71 and a second portion 22 connected to the lower end of the first portion 21.

[0037] The first portion 21 faces the headboard 4. The first portion 21 is, for example, substantially parallel to a YZ plane defined by the width direction Y and the vertical direction Z. The second portion 22 is, for example, substantially parallel to an XY plane defined by the longitudinal direction X and the width direction Y. The length of the first portion 21 in the width direction Y is, for example, smaller than the length of the second portion 22 in the width direction Y, but is not limited to this example.

[0038] 6 to 8, the fixing plate 40 is provided on the frame material 71. The first mounting member 20 and the fixing plate 40 are arranged in this order in the longitudinal direction X. The fixing plate 40 is located, for example, between the first mounting member 20 and the horizontal beam 73 in the longitudinal direction X.

[0039] The fixing plate 40 is formed of a plate material. The fixing plate 40 extends elongatedly in, for example, the width direction Y. The fixing plate 40 extends from the frame material 71 in the direction opposite to the width direction Y.

[0040] The fixing plate 40 has a through hole 41 (shown in FIG. 8) and a slit 42. The through hole 41 and the slit 42 are aligned in this order in the width direction Y. The through hole 41 and the slit 42 pass through the fixing plate 40.

[0041] 6 to 8, the lever member 50 is provided to the frame material 71 via the fixed plate 40. The lever member 50 and the frame material 71 are arranged in this order in the width direction Y.

[0042] The lever member 50 is formed of, for example, a metal material, but may be formed of other materials such as a resin material. The lever member 50 is formed of a plate material. The lever member 50 extends elongatedly in, for example, the vertical direction Z.

[0043] The lever member 50 has surfaces 51 and 52, through holes 53, 54, and 55, a tapered portion 56, and a claw portion 57. The surface 51 faces the headboard 4, and the surface 52 is the surface opposite to the surface 51. The surface 51 is in contact with the fixed plate 40.

[0044] 8, the through holes 53, 54, and 55 penetrate the surface 51 and the surface 52. The through holes 53, 54, and 55 are aligned in this order in the vertical direction Z. The through hole 54 overlaps with the through hole 41 of the fixing plate 40 in the longitudinal direction X.

[0045] 7, the through hole 55 is an elongated hole that is long in the width direction Y. The through hole 55 may be circular, rectangular, or another shape. As shown in FIG. 5, a pin 70 is passed through the through hole 55.

[0046] The tapered portion 56 is located above the through-hole 55. From another perspective, the tapered portion 56 is located above the first mounting member 20, as shown in FIGS. 6 to 8. The tapered portion 56 includes an upper end 561 of the lever member 50. The tapered portion 56 is inclined with respect to the vertical direction Z. More specifically, the tapered portion 56 is inclined along the vertical direction Z so that the surface 51 is away from the headboard 4.

[0047] The claw portion 57 is provided on the side end of the lever member 50 on the frame material 71 side. As shown in FIG. 6, the claw portion 57 is passed through the slit 42 of the fixing plate 40 and protrudes toward the headboard 4. By passing the claw portion 57 through the slit 42 of the fixing plate 40, movement and tilting of the lever member 50 in the width direction Y are restricted.

[0048] The support mechanism 60 supports the lever member 50 relative to the fixed plate 40. The support mechanism 60 has fixed members 61 and 62, an elastic member 63, and a holding member 64.

[0049] The fixing member 61 includes, for example, a bolt 611 and a nut 612. As shown in Fig. 8 , the bolt 611 is passed through the through hole 54 of the lever member 50 and the through hole 41 of the fixing plate 40 from the direction opposite to the longitudinal direction X.

[0050] The nut 612 is connected to the bolt 611 in the longitudinal direction X, with the fixed plate 40 and the lever member 50 sandwiched between them. As a result, the lever member 50 is supported relative to the fixed plate 40.

[0051] The elastic member 63 is located below the through-hole 55. The elastic member 63 is located between the lever member 50 and the head portion 6111 (shown in FIG. 8) of the bolt 611. The elastic member 63 is, for example, a spring, but is not limited to this example.

[0052] The spring is, for example, a coil spring. The spring is made of, for example, a metal material, but may be made of other materials. A plain washer 65 may be provided between the elastic member 63 and the lever member 50. This allows the elastic member 63 to stably bias the lever member 50.

[0053] 8, the bolt 611 has a step portion 6112. The bolt 611 is positioned relative to the fixed plate 40 by the step portion 6112. This makes it possible to adjust, for example, the position of the bolt 611 relative to the lever member 50 or the biasing force of the elastic member 63.

[0054] In the example shown in FIG. 8 , the holding member 64 is provided on the surface 51 of the lever member 50. The holding member 64 is located below the through-hole 54 and the fixing member 61. The holding member 64 is, for example, an attraction member. In one example, the attraction member is a magnet. The holding member 64 has, for example, a disk shape, but is not limited to this example. An end surface 641 of the holding member 64 on the headboard 4 side is, for example, substantially parallel to the YZ plane.

[0055] The fixing member 62 includes, for example, a bolt 621 and a nut 622. As shown in Fig. 8 , the bolt 621 is passed through a through-hole 642 formed in the holding member 64 and through the through-hole 53 of the lever member 50 from the longitudinal direction X. The nut 622 is connected to the bolt 621 from the direction opposite to the longitudinal direction X, with the lever member 50 sandwiched therebetween.

[0056] As a result, the holding member 64 is fixed to the lever member 50. In the example shown in FIG.

[0057] The second mounting member 30 is attached to the first mounting member 20. The headboard 4 is attached to the bed frame 2 by attaching the second mounting member 30 to the first mounting member 20. The two second mounting members 30 are aligned in the width direction Y, as shown in FIG. 3 .

[0058] 5 and 9, the second attachment member 30 is provided on the headboard 4. The second attachment member 30 is made of, for example, a metal material, but may also be made of other materials such as a resin material.

[0059] The second mounting member 30 is formed of a plate material. The second mounting member 30 has a substantially rectangular shape when viewed in the direction opposite to the longitudinal direction X. The second mounting member 30 has a base portion 31, a protrusion 32, and a notch portion 33.

[0060] The second attachment member 30 is fixed to the headboard 4 by, for example, four screws 80 via a base portion 31. The base portion 31 has through holes formed therein for the screws 80 to pass through. The base portion 31 has a surface 311. The surface 311 faces the lever member 50.

[0061] The protrusion 32 protrudes further in the longitudinal direction X than the base portion 31. In the example shown in Fig. 9, the protrusion 32 has a substantially rectangular shape when viewed in the direction opposite to the longitudinal direction X. The protrusion 32 is located in the center of the second mounting member 30 in the width direction Y.

[0062] As shown in FIG. 9, a gap G is formed between the headboard 4 and the protrusion 32. The gap G opens downward. The gap G has a size that allows the first portion 21 of the first attachment member 20 to be positioned therein. The gap G has, for example, a substantially rectangular parallelepiped shape that is elongated in the longitudinal direction X. The shape of the gap G can be changed as appropriate depending on the shape of the first attachment member 20, etc.

[0063] The notch 33 is located in the center of the protrusion 32 in the width direction Y. The notch 33 has an elongated shape in the longitudinal direction X. The notch 33 opens downward. The gap G and the notch 33 are connected.

[0064] 5, when the second mounting member 30 is attached to the first mounting member 20, the first portion 21 of the first mounting member 20 is positioned in the gap G, and the end of the frame material 71 is positioned in the cutout portion 33. In the example shown in FIG. 5, the lower end 321 of the second mounting member 30 is in contact with the upper surface 221 of the second portion 22 of the first mounting member 20.

[0065] 5 and 9, the pin 70 is provided to the headboard 4 via the second attachment member 30. In this embodiment, the headboard 4 corresponds to the other of the bed frame 2 and the headboard 4 on which the lever member 50 is not provided.

[0066] The pin 70 is provided on the surface 311 of the base portion 31. The pin 70 and the protrusion 32 are arranged in this order in the width direction Y. The position of the pin 70 in the width direction Y and the vertical direction Z is changed as appropriate depending on the position of the lever member 50.

[0067] The pin 70 is made of, for example, a metal material, but may be made of other materials such as a resin material. The pin 70 is made of, for example, the same material as the second mounting member 30. The pin 70 has, for example, a cylindrical shape, but may also have a rectangular pillar shape or other shapes.

[0068] The pin 70 protrudes toward the lever member 50. In the example shown in FIG. 9, the pin 70 protrudes in the longitudinal direction X. The pin 70 protrudes further than the protrusion 32 of the second mounting member 30.

[0069] 6 to 9, the mounting mechanism 100 on the frame member 71 side of the extension frame 7 has been described, but the mounting mechanism 100 on the frame member 72 side of the extension frame 7 has the same configuration.

[0070] That is, the attachment mechanism 100 on the frame material 72 side of the extension frame 7 includes a first attachment member 20, a second attachment member 30, a fixed plate 40, a lever member 50, a support mechanism 60, and a pin 70. The attachment mechanism 100 on the frame material 72 side has a structure that is plane-symmetrical with respect to the attachment mechanism 100 on the frame material 71 side with respect to the XZ plane defined by the longitudinal direction X and the vertical direction Z.

[0071] In the attachment mechanism 100 on the frame material 72 side, the first attachment member 20 is provided at one end of the frame material 72, and the fixing plate 40 is provided on the frame material 72 and extends in the width direction Y from the frame material 72.

[0072] In the attachment mechanism 100 on the frame material 72 side, the lever member 50 is attached to the frame material 72 via the fixing plate 40. In the attachment mechanism 100 on the frame material 72 side, the claw portion 57 of the lever member 50 is provided on the side end of the lever member 50 on the frame material 72 side.

[0073] In the mounting mechanism 100 on the frame material 72 side, when the second mounting member 30 is attached to the first mounting member 20, the first part 21 of the first mounting member 20 is positioned in the gap G, and the end of the frame material 72 is positioned in the cutout portion 33.

[0074] Next, a description will be given of the work of attaching and detaching the headboard 4 to and from the bed frame 2. Figures 10 and 11 are diagrams showing the operation of the lever member 50 according to this embodiment.

[0075] First, the position of the lever member 50 will be described. 10, the support mechanism 60 supports the lever member 50 so that it can be displaced between a first position P1 and a second position P2. The lever member 50 is rotatable about a rotation axis extending in the width direction Y by a fixed member 61 and an elastic member 63 of the support mechanism 60. The width direction Y is an example of a direction intersecting with the longitudinal direction X.

[0076] As a result, the lever member 50 is displaced between the first position P1 and the second position P2. In Figure 10, the lever member 50 at the first position P1 is shown by a solid line, and the lever member 50 at the second position P2 is shown by a dashed line.

[0077] 5, the position of the lever member 50 is a first position P1. At the first position P1, the lever member 50 extends, for example, along the vertical direction Z. When the second mounting member 30 is attached to the first mounting member 20, a pin 70 is passed through the through hole 55 at the first position P1. As shown in FIG. 10, the pin 70 has a length that allows it to protrude in the longitudinal direction X beyond the through hole 55 of the lever member 50.

[0078] At the first position P1, the pin 70 is passed through the through-hole 55, and therefore the headboard 4 is locked relative to the bed frame 2. Here, being locked means, for example, that sliding of the headboard 4 relative to the bed frame 2 in a direction parallel to the vertical direction Z is restricted.

[0079] Sliding in a direction parallel to the vertical direction Z refers to, for example, moving upward or downward. The second mounting member 30 is attached to the first mounting member 20 by sliding in a direction parallel to the vertical direction Z.

[0080] For example, at the second position P2, the lever member 50 is inclined with respect to the vertical direction Z. As the lever member 50 is inclined, the through-hole 55 moves away from the pin 70 in the longitudinal direction X. At the second position P2, the pin 70 is not inserted through the through-hole 55.

[0081] In the second position P2, the pin 70 is not passed through the through-hole 55, and therefore the headboard 4 is unlocked from the bed frame 2. Here, unlocking means, for example, that the headboard 4 is not restricted from sliding in a direction parallel to the vertical direction Z relative to the bed frame 2. For example, when the lever member 50 is in the second position P2, the headboard 4 can be moved upward relative to the bed frame 2.

[0082] The elastic member 63 biases the lever member 50 toward the first position P1. More specifically, the elastic member 63 biases the lever member 50 toward the fixed plate 40 via the plain washer 65 from the direction opposite to the longitudinal direction X. The lever member 50 is held at the first position P1 by the elastic member 63, for example, in a state in which the second mounting member 30 is not attached to the first mounting member 20.

[0083] When the lever member 50 is in the second position P2, the holding member 64 holds the lever member 50 to the headboard 4. At this time, the position of the lever member 50 is the second position P2. In the example shown in FIG. 10 , the holding member 64 holds the lever member 50 to the headboard 4 via a screw 80.

[0084] When the holding member 64 is a magnet, the holding member 64 is attracted to, for example, the screw 80. In other words, the holding member 64 comes into contact with the screw 80. The member that the holding member 64 attracts is not limited to the screw 80, but may be the second mounting member 30 or another member. The member that the holding member 64 attracts is formed, for example, from a material that can attract a magnet.

[0085] Next, the work of attaching the headboard 4 to the bed frame 2 will be described with reference to FIG.

[0086] When attaching the headboard 4 to the bed frame 2, the headboard 4 is slid downward relative to the bed frame 2. In other words, the second attachment member 30 is slid downward relative to the first attachment member 20. At this time, the pin 70 provided on the second attachment member 30 slides downward.

[0087] The lever member 50 has a tapered portion 56. As shown in Fig. 11, the tapered portion 56 is inclined so that the distance from the headboard 4 in the longitudinal direction X increases toward an upper end 561 of the lever member 50.

[0088] When the pin 70 slides downward, the pin 70 comes into contact with the lever member 50. More specifically, the tip of the pin 70 comes into contact with the tapered portion 56. The tip of the pin 70 is chamfered, for example, along the circumferential direction of the pin 70.

[0089] When the pin 70 slides downward from this state, the pin 70 pushes the tapered portion 56, causing the lever member 50 to rotate about a rotation axis extending in the width direction Y. More specifically, the lever member 50 rotates in a direction from the first position P1 toward the second position P2, thereby displacing the position of the lever member 50. In Figure 11, the lever member 50 is shown by a two-dot chain line in the middle of rotating from the first position P1 toward the second position P2.

[0090] When the pin 70 slides further downward from this state, the lever member 50 rotates further about the rotation axis extending in the width direction Y. As a result, the pin 70 slides further downward while contacting the surface 51 of the lever member 50. As a result, the second mounting member 30 is attached to the first mounting member 20, and when the pin 70 overlaps with the through-hole 55 in the longitudinal direction X, the headboard 4 is attached to the bed frame 2.

[0091] At this time, the lever member 50 is released from contact with the pin 70, and the position of the lever member 50 is displaced to the first position P1 by the elastic member 63. As a result, the lever member 50 locks the headboard 4 to the bed frame 2. Note that the retaining member 64 does not come into contact with the screw 80 when attaching the headboard 4 to the bed frame 2.

[0092] Next, the operation of removing the headboard 4 from the bed frame 2 will be described.

[0093] First, the position of the lever member 50 is displaced from the first position P1 to the second position P2 (shown in FIG. 10). At this time, the positions of the lever member 50 located on the frame member 71 side and the lever member 50 located on the frame member 72 side are both displaced. The user can rotate the lever member 50, for example, by pushing the tapered portion 56 in a direction to displace it to the second position P2.

[0094] The positions of the lever members 50 are held at the second position P2 by the holding members 64. This unlocks the headboard 4 from the bed frame 2. As a result, the headboard 4 can be removed from the bed frame 2 by sliding it upward relative to the bed frame 2.

[0095] 2 to 11, the headboard 4 and its surrounding structure have been described, and the footboard 5 and its surrounding structure are similar. That is, the attachment mechanism 100 on the footboard 5 side includes a first attachment member 20, a second attachment member 30, a fixing plate 40, a lever member 50, a support mechanism 60, and a pin 70.

[0096] Therefore, the work of attaching and detaching the footboard 5 to and from the bed frame 2 is similar to the work of attaching and detaching the headboard 4 to and from the bed frame 2, which has been described with reference to FIGS.

[0097] The bed apparatus 1 configured as described above can efficiently perform the work of attaching and detaching the board member to and from the bed frame 2. More specifically, the bed apparatus 1 includes a lever member 50 that is supported by the support mechanism 60 so as to be displaceable between a first position P1 and a second position P2.

[0098] At the first position P1, the pin 70 is passed through the through-hole 55 of the lever member 50, thereby locking the headboard 4 to the bed frame 2. At the second position P2, the through-hole 55 of the lever member 50 is separated from the pin 70, thereby releasing the headboard 4 from the bed frame 2.

[0099] That is, by displacing the lever member 50 between the first position P1 and the second position P2, the headboard 4 can be locked and unlocked relative to the bed frame 2.

[0100] This makes it easier for the user to lock and unlock the headboard 4 when attaching and detaching the headboard 4 to and from the bed frame 2. It also reduces the time required for the user to lock and unlock the headboard 4. As a result, with the bed apparatus 1 according to this embodiment, the headboard 4 can be attached to and detached from the bed frame 2 efficiently.

[0101] The footboard 5 and its surrounding structure are the same as the headboard 4 and its surrounding structure described with reference to Figures 2 to 11. That is, with the bed apparatus 1 according to this embodiment, the work of attaching and detaching the board member to and from the bed frame 2 can be performed efficiently. This reduces the labor and time required for assembling and disassembling the bed apparatus 1.

[0102] In this embodiment, the support mechanism 60 has an elastic member 63. The elastic member 63 biases the lever member 50 toward the first position P1, and therefore, the lever member 50 can be held at the first position P1.

[0103] In this embodiment, the second mounting member 30 is attached to the first mounting member 20 by sliding it along the vertical direction Z. At this time, when the second mounting member 30 is slid relative to the first mounting member 20 from a state in which the second mounting member 30 is not attached to the first mounting member 20, the pin 70 comes into contact with the lever member 50, causing the lever member 50 to be displaced from the first position P1 toward the second position P2.

[0104] More specifically, the lever member 50 is supported by a support mechanism 60 so as to be rotatable between a first position P1 and a second position P2 about a rotation axis extending in the width direction Y, and the lever member 50 has a tapered portion 56. The tapered portion 56 is inclined so that the distance from the headboard 4 in the longitudinal direction X increases as the lever member 50 approaches an upper end 561 of the lever member 50.

[0105] Therefore, when the pin 70 slides downward, the pin 70 comes into contact with the lever member 50. When the pin 70 slides downward from this state, the pin 70 presses the tapered portion 56 of the lever member 50, causing the lever member 50 to rotate. This allows the pin 70 to slide further downward, and the second mounting member 30 is attached to the first mounting member 20.

[0106] In this way, the user can attach the headboard 4 to the bed frame 2 by sliding the headboard 4 downward relative to the bed frame 2 without any special operation.

[0107] Furthermore, the lever member 50 is displaced to the first position P1 by the elastic member 63. This allows the user to lock the headboard 4 to the bed frame 2 without any special operation. As a result, the work of attaching the headboard 4 to the bed frame 2 can be performed more efficiently.

[0108] In this embodiment, the support mechanism 60 has a holding member 64. The holding member 64 holds the lever member 50 on the headboard 4 when the lever member 50 is in the second position P2.

[0109] This allows the user to displace the lever member 50 to the second position P2 in advance, facilitating the work of attaching the headboard 4 to the bed frame 2. In other words, the headboard 4 can be kept unlocked from the bed frame 2.

[0110] In this embodiment, two lever members 50 are provided in the width direction Y, but the two lever members 50 can be displaced to the second position P2 by the holding member 64, so that even a single user can easily remove the headboard 4.

[0111] In this embodiment, the user can attach and detach the board member to and from the bed frame 2 without using tools or the like.

[0112] 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.

[0113] In the present embodiment, the bed apparatus 1 is illustrated as including the headboard 4 and the footboard 5. As another example, the bed apparatus 1 does not necessarily have to include at least one of the headboard 4 and the footboard 5.

[0114] In this embodiment, the pin 70 is provided on the board member and the lever member 50 is provided on the bed frame 2, but the pin 70 may be provided on the bed frame 2 and the lever member 50 may be provided on the board member.

[0115] In this embodiment, the pin 70 is provided on the base portion 31 of the second mounting member 30, but the pin 70 may be provided on the protrusion 32 of the second mounting member 30, or on another portion of the headboard 4. The position at which the lever member 50 is provided is changed as appropriate depending on the position at which the pin 70 is provided. In this embodiment, the elastic member 63 is a spring, but the elastic member 63 may also be rubber or the like.

[0116] In this embodiment, the retaining member 64 holds the lever member 50 to the headboard 4 via a screw 80, but the retaining member 64 may also hold the lever member 50 to the headboard 4 via a second mounting member 30, or may hold the lever member 50 directly to the headboard 4.

[0117] In this embodiment, the retaining member 64 is a magnet, but the retaining member 64 may be configured, for example, by a pair of members. For example, one of the pair of members is a male member and the other is a female member. When the lever member 50 is provided on the bed frame 2, the female member may be provided on the board member and the male member may be provided on the lever member 50. As yet another example, the retaining member 64 may be a hook-and-loop fastener.

[0118] In this embodiment, the portion of the lever member 50 where the holding member 64 is provided extends along the vertical direction Z, but the shape may be changed as appropriate so that the holding member 64 can easily hold the lever member 50 at the second position P2. For example, the lower end side of the lever member 50 may be inclined so that the end surface 641 of the holding member 64 and the surface 311 are parallel to each other at the second position P2.

[0119] The first position P1 and the second position P2 of the lever member 50 in this embodiment are merely examples. The first position P1 is, for example, a position where the board member is locked to the bed frame 2, and the lever member 50 may be inclined with respect to the vertical direction Z at the first position P1. The second position P2 is, for example, a position where the board member is unlocked from the bed frame 2, and the lever member 50 may be inclined with respect to the vertical direction Z at an angle different from that in the above example at the second position P2.
