[0110] Reference Figures 1-15 The bed according to an embodiment of the present invention will be described.

[0111] Figure 1 This is a perspective view of a bed according to an embodiment of the present invention.

[0112] Figure 2 It means from Figure 1 The frame in the image shows the state after the base plate has been removed.

[0113] Figure 1 The bed 10 shown is an electric bed for use in, for example, nursing facilities, hospitals, and private residences, where the backrest, height, etc., can be operated electrically. However, the bed 10 is not limited to electric beds. The bed 10 includes: a frame 12; a plurality of base plates 20 disposed on the frame 12 and arranged in the front-to-back direction; and a first edge member 30 disposed at the end 24a of the base plate 20. Figure 1 The bed 10 shown Figure 1 The upper left side of the middle is the head side. Figure 1 The right-lower side is the foot side. In this embodiment, the direction between the head side and the foot side is the front-back direction.

[0114] like Figure 2 As shown, the frame 12 is located above the legs 14 and is generally frame-shaped. The frame 12 has multiple plate members connected in the front-to-back direction, for example. The frame 12 has, for example, a separable head-side frame 12a and a foot-side frame 12b. Thus, the bed 10 can be divided into multiple units, allowing it to be moved into the room where the bed 10 is located. Furthermore, the frame 12 can move vertically relative to the legs 14 via a drive unit located within it.

[0115] Multiple base plates 20 are arranged along the front-to-back direction on the frame 12. A mattress (not shown) is placed on top of the base plates 20, and the base plates 20 support the mattress and the human body on the mattress. The base plates 20 have: a back base plate 20a located on the head side to support the spine; a lumbar base plate 20b located behind the back base plate 20a to support the waist; a knee base plate 20c located behind the lumbar base plate 20b to support the knees; and a foot base plate 20d located behind the knee base plate 20c to support the feet. The back base plate 20a, lumbar base plate 20b, knee base plate 20c, and foot base plate 20d can be bent upwards by a drive unit provided in the frame 12.

[0116] An end component is provided at end 24a of the base plate 20 for easy attachment and detachment. This end component has mattress guards 60 for the first edge component 30 and the second edge component 50, described later. The end component can be mounted to end 24a of the base plate 20 in several different ways.

[0117] Figure 3 It means from Figure 1 An exploded perspective view of the first edge component after the end of the base plate has been removed.

[0125] Figure 11 Is with Figure 3 The same exploded perspective view showing the state after the first edge component has been removed from the end of the base plate.

[0126] Figure 12 It indicates viewing from the upper right. Figure 11 An exploded perspective view of the first edge component and the base plate.

[0127] like Figure 3 As shown, the base plate 20 has: a pair of cylindrical portions 22 that are opposite each other in the front-rear direction and extend in the left-right direction; an upper surface portion 24 that connects the upper ends of the pair of cylindrical portions 22; and a side surface portion 28 that extends downward from the left-right end 24a of the upper surface portion 24. Figure 3 Only one end 24a of the base plate 20 is shown, but the other end is formed in the same way. The upper surface portion 24 has a recess 26 that is recessed downward from the upper surface 24b. The side 26a of the recess 26 is formed at a position corresponding to the engaging portion 45 of the first edge member 30, which will be described later.

[0128] The side portion 28 extends from the end 24a of the upper surface portion 24 to the midway along the thickness direction (vertical direction) of the base plate 20. That is, the end 24a side of the side portion 28 is a fixed end, and the lower end is a free end. The side portion 28 is located on the end 24a side and extends in the vertical direction. The vertical dimension L1 of the side portion 28 is set to correspond to the dimension L2 between the rib 40 of the first edge member 30 and the other side portion 34, which will be described later. These dimensions L1 and L2 will be explained later.

[0129] The protrusion 29 extends downward from the center of the side portion 28 in the front-rear direction. This protrusion 29 is located above the lower end of the base plate 20, and when the first edge member 30 (described later) is installed at the end 24a of the base plate 20, the protrusion 29 is located inside the first edge member 30. The protrusion 29 engages with the engaging portion 45 of the first edge member 30 (described later).

[0130] Next, the first edge member 30 (end member) provided at the end 24a of the base plate 20 will be described.

[0131] The first edge member 30 is made of, for example, resin or metal and is formed into a bottomed cylindrical shape. The first edge member 30 is detachably provided at the end 24a of the base plate 20. The first edge member 30 is mounted on the base plate 20 by rotating 180 degrees in the vertical direction, thereby allowing the protrusion dimension protruding from the end 24a (side portion 28) of the base plate 20 to be changed.

[0132] Furthermore, the first edge member 30 has: a side face 32 located on one side in the vertical direction; another side face 34 opposite to the side face 32 in the vertical direction; an opening 36 for inserting the end 24a of the base plate 20; and a bottom 38 opposite to the opening 36. The first edge member 30 (end member) can be installed in reverse in the vertical or horizontal direction at the same position on the end 24a of the base plate 20.

[0133] One side face 32 and the other side face 34 become the upper or lower surface portion of the first edge member 30 by means of mounting the first edge member 30 to the end 24a of the base plate 20. Specifically, as Figures 1 to 7 As shown, when the width of the bed 10 in the left-right direction is set to be relatively wide, one side surface 32 becomes the upper surface portion, and the other side surface 34 becomes the lower surface portion. On the other hand, as... Figures 8-12 As shown, when the width of the bed 10 in the left-right direction is set to be relatively narrow, one side surface 32 becomes the lower surface portion, and the other side surface 34 becomes the upper surface portion. That is, as... Figure 8As shown, compared to the case where one side face 32 is set as the upper surface portion as shown by the double-dotted line, the insertion depth of the base plate 20 is deeper when the other side face portion 34 is set as the upper surface portion.

[0134] The two ends of one side face 32 and the other side face 34 in the front-rear direction are connected by a curved side face 35 formed corresponding to the outer shape of the cylindrical part 22 of the base plate 20. The opening 36 is shaped to correspond to the end 24a of the base plate 20 by the one side face 32, the other side face 34 and the curved side face 35.

[0135] The bottom 38 has: a shallow bottom 38a, which contacts the side portion 28 when one side portion 32 is used as the upper surface portion and the end portion 24a of the bottom plate 20 is inserted into the opening portion 36; and a deep bottom 38b, which contacts the side portion 28 when the other side portion 34 is used as the upper surface portion and the end portion 24a of the bottom plate 20 is inserted into the opening portion 36.

[0136] The shallow bottom 38a and the deep bottom 38b are formed by ribs 40 provided inside the first edge member 30. Specifically, the ribs 40 extend from one side face 32 toward the other side face 34 and protrude from the deep bottom 38b toward the opening 36, with the protruding end face becoming the shallow bottom 38a. In this embodiment, for example, four ribs 40 are provided. In addition, the number of ribs 40 can be one to three, or five or more.

[0137] like Figures 5-7 As shown, when one side surface 32 is installed as the upper surface portion to the end 24a of the base plate 20, the shallow bottom 38a, which is the protruding end face of the rib 40, contacts the side surface 28 of the base plate 20.

[0138] This restricts the first edge component 30 from being further inserted into the base plate 20. Additionally, as... Figure 7 As shown, the first edge member 30 becomes a protruding dimension W1 protruding from the end 24a of the base plate 20, thereby enabling the width of the bed 10 to be set wider.

[0139] Furthermore, the rib 40, by connecting to one side of the face 32, also serves as a reinforcing member for strengthening that side of the face 32. Additionally, as... Figure 7 As shown, the back surface 32a of one side of the face 32 contacts the upper surface portion 24 of the base plate 20. For example, when the user of the bed 10 adopts a sitting posture on the end 24a side of the base plate 20, a force (body weight) is applied from above the one side of the face 32. In such a case, the force can be borne by the upper surface portion 24 and the ribs 40 of the base plate 20, thereby suppressing deformation of the one side of the face 32.

[0140] The dimension L2 between rib 40 and the other side surface 34 is formed to be larger than the vertical dimension L1 of the side surface 28 of the base plate 20. Therefore, Figure 9 As shown, a space S1 is formed between the rib 40 and the other side surface 34 for the side surface 28 to be inserted. Furthermore, the dimension L3 between the two central ribs 40 is larger than the front-rear dimension L4 of the protrusion 29 of the base plate 20. Thus, a space S2 is formed between the two central ribs 40 for the protrusion 29 to be inserted.

[0141] Therefore, as Figures 8-10 As shown, when the first edge member 30 has the other side portion 34 as the upper surface portion and the end 24a of the base plate 20 is inserted from the opening 36, the side portion 28 of the base plate 20 passes through the space S1 between the rib 40 and the other side portion 34, and the side portion 28 contacts the deep bottom 38b.

[0142] This restricts the first edge component 30 from being further inserted into the base plate 20. Additionally, Figure 10 As shown, the first edge member 30 has a protruding dimension W2 that protrudes from the end 24a of the base plate 20, thereby enabling the width of the bed 10 to be set narrower. That is, since the first edge member 30 is installed on both ends of the base plate 20, the width dimension of the bed 10 can be reduced by an amount of 2×(W1-W2).

[0143] like Figure 10 As shown, in this case, the other side portion 34 contacts the upper surface portion 24 of the base plate 20 over a wide area of ​​the back surface 34a. Therefore, even if, for example, a user of the bed 10 assumes a sitting posture on the end 24a side of the base plate 20 and applies force (body weight) from above the other side portion 34, the upper surface portion 24 of the base plate 20 can withstand this force. Thus, deformation of the other side portion 34 can be suppressed.

[0144] The engaging portion 45 is provided on the other side portion 34. The engaging portion 45 extends from the surface 34b of the other side portion 34 toward the interior of the first edge member 30. The engaging portion 45 is provided at positions corresponding to the recess 26 of the base plate 20 and the protrusion 29 of the base plate 20.

[0145] like Figure 7 , Figure 10 As shown, the top end 45a of the engaging portion 45 is located closer to the opening 36 than the shallow bottom 38a. Figure 7 As shown, when the first edge member 30 has one side face 32 as the upper surface and the end 24a of the base plate 20 is inserted from the opening 36, it is prevented from falling off by engaging with the back side 29a of the protrusion 29 by the engaging part 45.

[0146] On the other hand, such as Figure 10As shown, when the other side portion 34 is used as the upper surface portion and the end 24a of the base plate 20 is inserted into the opening 36, the first edge member 30 is prevented from detaching by engaging with the side 26a of the recess 26 via the engaging portion 45. By pressing towards the surface 34b of the other side portion 34, the engaging portion 45 can be released.

[0147] Next, the second edge member 50 will be described. The second edge member 50 is provided on a base plate 20 that is different from the base plate 20 on which the first edge member 30 is provided.

[0148] Figure 13 It means Figure 1 Top view of the second edge component, mattress stopper (end component), and base plate.

[0149] Figure 14 Viewed from the direction of arrow EE Figure 13 A cross-sectional view of the second edge component, mattress baffle, and base plate.

[0150] Figure 15 Is with Figure 14 The same cross-sectional view shows the case where the mattress inserts are set to be narrower.

[0151] Figure 16 It is an exploded perspective view showing the state after the second edge component has been removed from the base plate and the mattress retainer has been removed from the second edge component.

[0152] The mattress stop 60 (end part) is movable horizontally on the upper surface of the end 24a of the base plate 20, so that it can be installed in multiple different positions.

[0153] The second edge member 50 is made of, for example, resin or metal, and has an upper surface 51, a lower surface 52, a curved side 53, and a bottom 54. An opening 55 is formed between the second edge member 50 and the bottom 54. That is, the second edge member 50 is formed as a bottomed cylindrical shape.

[0154] The second edge member 50 is configured to span multiple adjacent base plates 20 in the front-rear direction. For example... Figure 1 As shown, the second edge member 50 is provided on, for example, the back base plate 20a and the foot base plate 20d. That is, the second edge member 50 is provided between the base plates 20 that are not bent by the drive unit.

[0155] The second edge member 50 has a mattress stop mounting portion 51a on its upper surface portion 51. This mattress stop mounting portion 51a is located, for example, between adjacent base plates 20. The mattress stop mounting portion 51a has a first through hole 56 and a second through hole 57 extending from the upper surface portion 51 to the lower surface portion 52. The first through hole 56 and the second through hole 57 are arranged in a left-right direction. A mattress stop 60 is detachably mounted in the first through hole 56 and the second through hole 57.

[0156] like Figure 14 , Figure 15 As shown, the lower surface portion 52 of the second edge member 50 has an engaging portion 58. This engaging portion 58 is formed identically to the engaging portion 45 of the first edge member 30 and engages with the protruding portion 29 of the base plate 20. The second edge member 50 is prevented from detaching by engaging the engaging portion 58 with the protruding portion 29. The engaging portion 58 may correspond to at least one base plate 20 on which the second edge member 50 is mounted, or it may correspond to multiple base plates 20 respectively.

[0157] A mattress stopper 60 is detachably mounted on the mattress stopper mounting portion 51a. This mattress stopper 60 suppresses the shifting of a mattress (not shown) placed on the upper surface portion 24 of the base plate 20. Furthermore, the mattress stopper 60 includes: a horizontal plate portion 62 mounted on the mattress stopper mounting portion 51a; a first protrusion 64 and a second protrusion 66 extending downward from the horizontal plate portion 62 and arranged in a left-right direction; and a limiting portion 68 extending upward from the end of the horizontal plate portion 62 opposite to the base plate 20.

[0158] The mattress stopper 60 can change the protrusion dimension of the part protruding from the end 24a of the base plate 20. Specifically, as... Figure 16 As shown by the dotted lines, the mattress stopper 60 is configured to have a wider width by inserting the first protrusion 64 through the first through hole 56 and the second protrusion 66 through the second through hole 57, and then mounting the horizontal plate portion 62 onto the mattress stopper mounting portion 51a. Figure 13 , Figure 14 (State). In this case, the protruding dimension of the mattress stopper 60 protruding from the end 24a of the base plate 20 corresponds to the case where one side face 32 of the first edge member 30 is installed as the upper surface portion of the base plate 20.

[0159] On the other hand, such as Figure 16 As shown by the single-dotted line, the mattress stopper 60 is configured to have a narrow width by inserting the first protrusion 64 through the opening 55 and the second protrusion 66 through the first through hole 56, and mounting the horizontal plate portion 62 to the mattress stopper mounting portion 51a. Figure 15(State). In this case, the protruding dimension of the mattress stopper 60 protruding from the end 24a of the base plate 20 corresponds to the case where the other side portion 34 of the first edge member 30 is mounted as the upper surface portion to the base plate 20.

[0160] Thus, the bed 10 of this embodiment has: a plurality of base plates 20 arranged in the front-to-back direction on the frame 12; and a bottomed cylindrical first edge member 30 provided at the end 24a of the base plate 20. The base plate 20 has a side portion 28 located at the end side in the left-right direction and extending in the vertical direction. The first edge member 30 has: a side portion 32 located on one side in the vertical direction; another side portion 34 opposite to the side portion 32; an opening 36 for inserting the end 24a of the base plate 20; and a bottom 38 opposite to the opening 36. The bottom 38 has: a shallow bottom 38a, which contacts the side portion 28 when the side portion 32 is used as the upper surface portion and the end 24a of the base plate 20 is inserted through the opening 36; and a deep bottom 38b, which contacts the side portion 28 when the other side portion 34 is used as the upper surface portion and the end 24a of the base plate 20 is inserted through the opening 36.

[0161] Therefore, when the first edge member 30 is mounted to the base plate 20 with one side face 32 as the upper surface, the bed 10 can be set to be wider. On the other hand, when the first edge member 30 is mounted to the base plate 20 with the other side face 34 as the upper surface, the bed 10 can be set to be narrower. That is, simply by reversing the mounting direction of the first edge member 30, the width of the bed 10 can be easily changed from wider to narrower or vice versa.

[0162] Additionally, the side portion 28 extends downward from the upper surface portion 24 of the base plate 20, and the bottom 38 has a rib 40 that extends from one side portion 32 toward the other side portion 34 and protrudes from the deep bottom 38b toward the opening 36, with the protruding end face becoming the shallow bottom 38a. When the other side portion 34 is used as the upper surface portion and the end 24a of the base plate 20 is inserted into the opening 36, the side portion 28 is inserted into the space S1 between the rib 40 and the other side portion 34.

[0163] Thus, the rib 40 functions as a spacer for setting the width dimension of the bed 10 and as a reinforcement for reinforcing the first edge member 30. Therefore, when, for example, a user of the bed 10 is sitting upright on the bed 10, deformation of the first edge member 30 can be suppressed even when force (body weight) is applied from above the first edge member 30.

[0164] In addition, the side portion 28 has a protrusion 29 extending downward, and the other side portion 34 has a locking portion 45. When one side portion 32 is used as the upper surface portion and the end 24a of the base plate 20 is inserted from the opening portion 36, the locking portion 45 engages with the protrusion 29.

[0165] In addition, the upper surface portion 24 of the base plate 20 has a recess 26 that is recessed downwards. When the other side portion 34 is used as the upper surface portion and the end portion 24a of the base plate 20 is inserted through the opening portion 36, the engaging portion 45 engages with the recess 26.

[0166] Therefore, it is possible to prevent the first edge component 30 from falling off the base plate 20 due to, for example, friction with the mattress.

[0167] In addition, when the other side portion 34 is used as the upper surface portion and the end portion 24a of the base plate 20 is inserted through the opening portion 36, the other side portion 34 contacts the upper surface portion 24 of the base plate 20.

[0168] Therefore, when a user of bed 10 is sitting upright on bed 10, even if a force (body weight) is applied from above the first edge member 30, the force can be borne by the upper surface portion 24 of the base plate 20 via the other side portion 34 of the first edge member 30. Thus, deformation of the first edge member 30 can be suppressed.

[0169] The second edge member 50 is provided on a base plate 20 that is different from the base plate 20 provided with the first edge member 30. The second edge member 50 has a mattress stop 60 that suppresses the displacement of a mattress placed on the base plate 20. The mattress stop 60 is capable of changing the protrusion size of the protrusion from the end 24a of the base plate 20.

[0170] Therefore, the protruding dimensions of the mattress stopper 60 can be easily changed, thus suppressing mattress shift even when the mattress is changed to a different width.

[0171] In addition, the second edge component 50 is configured to span multiple adjacent base plates 20 in the front-rear direction.

[0172] Therefore, the second edge component 50 can be installed on multiple base plates 20 at once, thereby improving the operability of installing the second edge component 50 on the base plate 20 and reducing the number of parts.

[0173] like Figure 1 As shown, the first edge member 30 and the second edge member 50 are mounted together on the bed 10. Since a single second edge member 50 can be arranged across multiple base plates 20, the operability of mounting to the base plates 20 is improved, and the number of parts is reduced. On the other hand, in cases such as Figure 1When the bed 10 shown has a backrest base 20a, knee base 20c, and foot base 20d that can be bent by a drive unit, the positions where the second edge member 50 can be installed are limited.

[0174] like Figure 1 As shown, the bed 10 has a first edge member 30 provided on the base plate 20 around the lumbar base plate 20b where the user frequently assumes a sitting posture at the end 24a side of the base plate 20, and a second edge member 50 provided on the base plate 20 of the back base plate 20a and foot base plate 20d where the sitting posture is relatively less frequently assumed. That is, the first edge member 30 can support the ends of the mattress in both cases where it is set to be wider and cases where it is set to be narrower. Therefore, the first edge member 30 can improve stability when assuming a sitting posture.

[0175] Therefore, the bed 10 can improve the operability of mounting the first edge member 30 and the second edge member 50 to the base plate 20 and can reduce the number of parts. In this way, a bed 10 can be provided that simultaneously improves the operability of mounting to the base plate 20 and improves the convenience of the bed 10 by appropriately combining the first edge member 30 and the second edge member 50.

[0176] then, Figure 17 The third edge component represents the first variation.

[0177] Figure 17 This is an exploded perspective view of the third edge component of the first modified example. Figure 17 (a) is an exploded perspective view showing the base plate 70 and the third edge component 72 when the width is set to be relatively wide. Figure 17 (b) is an exploded perspective view showing the base plate 70 and the third edge member 72 when the width is set to be narrow. The third edge member 72 (end member) can be installed in the same position at the end of the base plate 70 in either the vertical or horizontal direction.

[0178] The base plate 70 has an internal thread 71 that extends vertically. Additionally, the third edge member 72 has a through hole 73 that extends vertically at a position corresponding to the internal thread 71. This through hole 73 is formed at an end side biased towards the left-right direction of the third edge member 72. Therefore, by rotating the third edge member 72 180 degrees and screwing the bolt 74 into the internal thread 71, the protrusion dimension of the third edge member 72 from the base plate 70 can be changed. Alternatively, the third edge member 72 can also be mounted to the base plate 70 using a pin instead of the bolt 74.

[0179] then, Figure 18 The fourth edge component (end component) represents the second variation.

[0180] Figure 18 This is an exploded perspective view of the fourth edge component of the second variant. Figure 18 (a) is an exploded perspective view of the base plate 70 and the fourth edge component 75 when the width is set to be wider. Figure 18 (b) is an exploded perspective view showing the base plate 70 and the fourth edge member 75 when the width is set to be narrow. The fourth edge member 75 (end member) can be installed in the same position at the end of the base plate 70 in a reverse manner along the vertical or horizontal direction. The fourth edge member 75 can move in the left-right direction along the end of the base plate 70, so that it can be installed in multiple different positions. The fourth edge member 75 can move horizontally on the upper or lower surface of the end of the base plate 70, so that it can be installed in multiple different positions.

[0181] The third edge member 72 is replaced by a fourth edge member 75. The fourth edge member 75 is formed with a first through hole 76 and a second through hole 77 arranged in the left-right direction. The fourth edge member 75 can change the protrusion size from the base plate 70 by screwing a bolt 74 into the first through hole 76, the second through hole 77 and an internal thread 71.

[0182] then, Figure 19 The fifth edge component (end component) represents the third variation.

[0183] Figure 19 These are top and side views showing the fifth edge component of the third variation. Figure 19 (a) is the top view when the width is set to be narrow. Figure 19 (b) is the side view when the width is set to be narrow. Figure 19 (c) is the top view when the width is set to be wider. Figure 19 (d) is a side view with the width set. The fifth edge member 81 (end member) can be installed in the same position at the end of the base plate 80 in either the vertical or horizontal direction.

[0184] A fifth edge member 81 is provided at one end of the base plate 80. This fifth edge member 81 is foldable relative to the base plate 80. A thin plate portion 82, for example, that is bendable, is provided between the base plate 80 and the fifth edge member 81. Figure 19 of (a), Figure 19 As shown in (b), the fifth edge member 81 can be configured to be narrower by being folded to the bottom plate 80. On the other hand, as Figure 19 (c) Figure 19 As shown in (d), the fifth edge component 81 can be set to be wider by unfolding from the base plate 80.

[0185] then, Figure 20 The sixth edge component (end component) represents the fourth variation.

[0186] Figure 20 This is a side view of the sixth edge component of the fourth variation. Figure 20 (a) is the side view set to a narrower width. Figure 20 (b) is a side view with the width set. The sixth edge member 86 can move in the left-right direction along the end of the base plate 85, thereby being installed in multiple different positions. The sixth edge member 86 can move horizontally on the upper or lower surface of the end of the base plate 85, thereby being installed in multiple different positions.

[0187] A sixth edge member 86 is provided at the end of the base plate 85. The sixth edge member 86 is capable of sliding relative to the base plate 85 in the left-right direction (width direction). The protrusion dimension of the sixth edge member 86 protruding from the base plate 85 can be finely adjusted by adjusting the sliding position.

[0188] then, Figure 21 The seventh edge component (end component) represents the fifth variation.

[0189] Figure 21 These are top and side views showing the seventh edge component of the fifth variation. Figure 21 (a) is the top view when the width is set to be narrow. Figure 21 (b) is a side view with a narrower width. The seventh edge member 95 can move vertically along the end of the base plate 90, allowing it to be installed in multiple different positions. The seventh edge member 95 is configured to span multiple adjacent and bent base plates 90 in the front-rear direction, and the seventh edge member 95 has a rotating part (hinge part 98) that rotates in conjunction with the bending of the base plate 90. In addition, the seventh edge member 95 can be moved horizontally along the end of the base plate 90, allowing it to be installed in multiple different positions.

[0190] In the above embodiments, an example is given of mounting the first edge member 30 to a plurality of base plates 20. However, as... Figure 21 As shown, a seventh edge component 95 capable of changing the width dimension can also be provided on the frame-shaped base plate 90.

[0191] The base plate 90 includes, for example, a back base plate 90a and a leg base plate 90b. The back base plate 90a can be angled relative to the leg base plate 90b via, for example, a drive unit (not shown). Furthermore, a through hole 92 extending vertically is formed in the tube 91a of the back base plate 90a. On the other hand, a through hole 92 extending vertically is also formed in the tube 91b of the leg base plate 90b.

[0192] The seventh edge member 95 includes a back base plate edge member 95a mounted on the back base plate 90a and a leg base plate edge member 95b mounted on the leg base plate 90b. The back base plate edge member 95a is formed in a U-shape, for example, to allow the insertion of a tube 91a. Furthermore, the back base plate edge member 95a has a first through hole 96 and a second through hole 97 extending vertically, arranged side-by-side in the horizontal direction (width direction). The leg base plate edge member 95b is formed in the same manner as the back base plate edge member 95a. The back base plate edge member 95a and the leg base plate edge member 95b are connected by a hinge portion 98 and are rotatable.

[0193] The seventh edge member 95 can be configured to be narrower by inserting the pin member 99 from the first through hole 96 into the through hole 92. On the other hand, the seventh edge member 95 can be configured to be wider by inserting the pin member 99 from the second through hole 97 into the through hole 92.

[0194] Figure 22 This is a side view showing the eighth edge component of the sixth variation.

[0195] In the above embodiment, a first edge member 30 that is movable up and down on the base plate 20 is illustrated. However, as... Figure 22 As shown, an eighth edge member 101 (end member) that can move vertically relative to the base plate 100 can also be provided. That is, the eighth edge member 101 can move vertically along the end of the base plate 100, thereby being installed in multiple different positions.

[0196] Furthermore, in the above embodiment, the example shown is that the side portion 28 extends downward from the upper surface portion 24. However, the present invention is not limited to this; for example, the side portion may also extend upward from the lower surface portion of the base plate. In this case, one side portion 32 of the first edge member 30 becomes another side portion, and the other side portion 34 becomes another side portion.

[0197] Furthermore, in the above embodiment, the shallow bottom 38a and deep bottom 38b are illustrated by forming a shallow bottom 38a and a deep bottom 38b through the rib 40. However, the present invention is not limited to this; for example, a stepped bottom may also be formed inside the first edge member 30.

[0198] Furthermore, in the above embodiment, an example was described where the second edge member 50 is installed across multiple base plates 20. However, the invention is not limited to this; for example, the second edge member with mattress guards may also be installed on a single base plate.
