Definitions

the present invention relates generally to a bed device configured to be able to perform vertically drive, back-raising drive or lateral rocking drive of a floor plate body on which a user lies on the back.
a user such as an elderly person or a sick person unable to turn over or raise its own body by itself must stay supine on the mattress of the bed device for a long time. If the user is in a supine position for a long time, bedsores may occur in the back of the body, especially in the buttocks, resulting in increase in pain.
bed devices disclosed in, for example, Patent Literatures 1 to 4 have been proposed.
the bed devices disclosed in Patent Literatures 1 to 4 comprise a base frame, and a vertical frame is provided on the base frame so as to be capable of being driven up and down.
a rocking frame (rotating frame) is supported by the vertical frame so as to be capable of tilting in the width direction.
the rocking frame is driven to tilt in the width direction with one end or the other end in the width direction serving as a fulcrum, by a rocking drive mechanism provided on the vertical frame.
a floor plate body is provided on the upper surface of the rocking described in Patent Literature 1.
the floor plate body has a central floor plate and side floor plates pivotally connected only upward to both sides of the central floor plate.
the central floor plate is divided into a plurality of floor parts in the longitudinal direction, which are pivotally connected to each other.
One of the floor parts that is located substantially at the center in the longitudinal direction is attached and fixed to the rocking frame.
the lower surface of one of the side floor plates positioned on one side in the width direction, that is, the lower side of the inclining direction contacts a contact member provided at an end portion of the vertical frame in the width direction and bends in a direction opposite to the inclining direction of the rocking frame, that is, an upward direction.
the rocking frame is tilted in the lateral direction, the user such as a patient who lies on the floor plate body can change his body position while being prevented from falling from the floor plate body by the side floor plate bent upward, and bedsores can be prevented.
the rocking frame is provided with a raise drive mechanism for raising the floor plate body (back-raising drive and leg-raising drive).
the raise drive mechanism is driven in the raising direction in a state in which the plurality of divided floor parts of the floor plate body are in a horizontal position. As a result, the user lying on the back on the floor plate body is supported by the floor parts with the upper body raised.
the raise drive mechanism may be operated to raise the upper body of the user.
tilting the body of the patient having the upper body raised in the lateral direction may be required.
the patient's body is often required to be maintained in the above-mentioned posture.
support rollers are rotatably provided with the axial line kept horizontal, at both end parts in the width direction of one end surface and the other end surface in the longitudinal direction.
Lateral rods are laid in the width direction at both ends in the longitudinal direction of the support frame, and a pair of receiving members having arc-shaped recess portions opened to the upper surface are attached and fixed to these lateral rods.
a pair of support rollers provided on both longitudinal end surfaces of the rocking frame are engaged with and supported by the recess portions of the receiving members.
a lateral rod is further laid in parallel with one lateral rod at one longitudinal end of the support frame, and rocking drive means for rocking the rocking frame in the width direction by using as a fulcrum the support roller on one end side in the width direction or the support roller on the other end side engaged with the recess portion of the receiving member are provided on the pair of lateral rods.
the rocking drive means includes a rocking drive source and a link mechanism driven by the rocking drive source.
the link mechanism is provided such that a pair of connection links driven in the vertical direction are pivotally provided at one side ends by operating the link mechanism by the rocking drive source.
the other end of each connection link is pivotally attached to a support shaft of a pair of support rollers provided on one longitudinal end surface of the rocking frame.
connection links are driven in the upward direction from the downward position in a state where the longitudinal direction of one of the connection links coincides with the vertical direction in accordance with the direction of driving the link mechanism.
the other connection link stands by at a position where the connection link does not move up and down (downward position).
the rocking frame is raised on the side of the support roller connected to the rising connection ring and is tilted, for example, leftward.
the rocking frame is driven to be tilted in a rightward direction, which is the direction opposite to the above.
the floor plate body disclosed in Patent Literature 3 is provided with a central floor plate and a pair of side floor plates capable of pivoting only in the upward direction on both sides in the width direction of the central floor plate.
the pair of side floor plates are set to a size that protrudes outward from both sides in the width direction of the rocking frame.
the central floor plate and the side floor plates are subjected to integral foam molding using resin. That is, the central floor plate and the side floor plates are subjected to foam molding such that the both sides of the central floor plate in the width direction and the upper ends in the thickness direction on both sides of the side floor plates in the widthwise direction are connected by the thin portion having flexibility over the entire length in the longitudinal direction.
the side floor plates are thereby pivotally connected only upward to the central floor plate in the horizontal state.
the side floor plates are only connected and supported only by the thin portions when the floor plate body is in the horizontal state. For this reason, if a load is applied to the upper surfaces of the side floor plates in that state, the thin portions may be broken. That is, the side floor plates cannot be pivotally connected to the central floor plate with sufficient strength by the only thin portions.
a plurality of lateral rod members such as pipe members are fixedly arranged at predetermined intervals in the longitudinal direction on the lower surface of the central floor plate of the floor plate body along the width direction.
the lateral rod member is formed to be longer than the width dimension of the central floor part.
a longitudinal rod member is connected to both ends of the lateral rod member, i.e., the ends of the lateral rod member located on the lower surface side of the side floor plate.
the bed device capable of performing vertical drive, back-raising drive or lateral rocking drive of the floor plate body on which the user lies on the back is complicated as compared with the conventional bed device, the bed device has various problems.
side fences 1102 are detachably attached on both sides (or one side) in the width direction of vertical frame 1101 as needed, as shown in FIG. 10 .
the side fences 1102 are used to prevent a patient lying on the back on a floor plate body 1103 placed on the vertical frame 1101 from falling down from the bed device or to prevent a quilt placed on the patient from slipping off.
one end side in the width direction of the back floor part 1104 of the floor plate body 1103 collides with one of the side fences 1102 as represented by a chain line in FIG. 10 . That is, when the angle at which the floor plate body 1103 is tilted in the width direction is larger than a predetermined angle, one end in the width direction which is on the lower side of the tilting direction of the back-raised back floor part 1104 of the floor plate body 1103 collides with the side fence 1102.
the rocking drive mechanism for tilting the floor plate body 1103 in the width direction and the raise drive mechanism for driving the floor plate body 1103 in a horizontal state in the raising direction are set to be unable to be driven simultaneously, to prevent the end portion of the floor board body from colliding with the side fence when tilting the floor board body.
the caregiver holds the patient's body such that the patient's body tilts in the width direction of the floor plate body 1103 or the posture is maintained in a tilted state by putting a cushion on the patient's back, in a state where the back floor part 1104 of the floor plate body 1103 is raised. For this reason, the burden on caregivers may increase and a desirable posture cannot be maintained reliably.
the rocking drive means is provided while connected with the support frame and the rocking frame. That is, although the rocking drive source of the rocking drive means and the main links of the link mechanism driven by the rocking drive source are provided on the support frame, the connection link to transmit the movement of the link mechanism to the rocking frame is provided by connecting the other end to a support shaft of a support roller provided on one end surface of the support frame.
rocking drive means in a preassembled state may be conveyed to the purchaser to facilitate the assembling work at the site.
the rocking drive means, the support frame and the rocking frame are handled in an integrated state. Since the integrated rocking drive means, support frame and rocking frame tend to be heavier and larger, handling them is not facilitated.
a plurality of lateral rod members have been arranged at predetermined intervals in the longitudinal direction and longitudinal rod members have been provided to be connected to both ends of the lateral rod members on the lower surface of the central floor part of the floor plate body.
the lateral rod member and the longitudinal rod member of the reinforcing member are often formed of a metal material such as a metal pipe so as to obtain predetermined strength and to be relatively inexpensive. For this reason, not only can the floor plate body provided with the reinforcing member increase its weight, but also it takes time and effort for processing of a metal material and assembling work to the central floor plate.
a bed device for nursing often comprises a back-raising function and a leg-raising function.
the central floor plate and a pair of side floor plates of the floor plate body are divided into a plurality of floor plate portions that are back raise portions and leg raise portions in the longitudinal direction and are connected pivotally.
Embodiments described herein aim to provide a bed device which enables its handling such as operations and assembling to be facilitated irrespective of a structure capable of performing vertical drive, back-raising drive or rocking drive of the floor plate body.

the rocking frame 231 has one end side in the width direction raised and is tilted.
the pair of first receiving members 277 are arranged close to the other side surface of the attachment member 275. Therefore, when the attachment member 275 is in the horizontal state as shown in FIG. 24 and FIG. 15 , rocking in the direction intersecting the longitudinal direction is prevented by the first receiving member 277 and the positioning portion 252a provided on one of the bearings 252.
connection link 269 Since the lower ends of the pair of connection links 269 are connected by the restriction link 272, the distance between the lower ends of the pair of connection links 269 does not change. In addition, the position of the lower end of the connection link 269 in the downward position does not shift in the leftward direction or the upward direction in FIG. 25 by engaging one of the connection shafts 271 with one of the engagement members 276.
connection link 269 having an upper end connected to the one end part in the upward direction is reliably displaced from the downward position to the upward position without being shifted to the leftward direction together with the attachment member 275, and one end side in the width direction of the rocking frame 231 is thereby raised reliably.
the guide shaft 265 is moved from the state shown in FIG. 24 in the direction opposite to that shown in FIG. 25 , that is, in the direction represented by arrow b in FIG. 26 .
the rocking frame 231 can be made to rock in an opposite direction, i.e., a direction in which the other end side in the width direction is raised.
connection shafts 271 engages with the L-shaped engagement member 276. Therefore, since the connection shaft 271 is reliably held by the engagement member 276, the rocking frame 231 may hardly rattle even if an inadvertent external force is applied to the rocking frame 231 which has rocked.
the engagement member 276 is attached to the attachment instrument 276a so as to be adjustable in position. For this reason, the engagement member 276 can also be therefore positioned such that the connection shaft 271 engages with the engagement member 276 without rattling.
the attachment member 275 to which the rocking frame 231 is connected is provided at the frame 250 so as to be able to rock, and furthermore, the link mechanism 270 for rocking the attachment member 275 and the rocking drive mechanism 257 for driving the link mechanism 270 are provided integrally with the frame 250.
the rocking drive unit 229 in which the attachment member 275 for rocking the rocking frame 231, the link mechanism 270, and the rocking drive mechanism 257 are integrated can be configured.
the end part of the lateral member 248 of the frame 250 is engaged with the receiving element 227 provided on the vertical frame 209, and they are connected by the connection shaft 287 so as to be disassembled as shown in FIG. 18 , and the rocking drive unit 229 can be thereby detachably assembled to the vertical frame 209.
the above-described main components for driving the rocking frame 231 to rock are integrated by the rocking drive unit 229.
the rocking drive unit 229 can be detachably assembled to the first frame part 209A of the vertical frames 209 quickly and easily without any skill.
the vertical frame 209 is disassembled into first and second frame portions 209A and 209B, and the rocking drive unit 229 is disassembled with respect to the vertical frame 209.
the vertical frame 209 divided into the first and second frame parts 209A and 209B is more lightweight than that in the assembled state, and furthermore, the vertical frame 209 is more lightweight as compared to the case where the rocking drive unit 229 is incorporated in the vertical frame 209, and their conveying operation and assembling operation can be therefore performed quickly and easily.
the pair of first receiving members 277 for supporting the pair of first receiving rollers 274 are provided at the attachment member 275 to which the rocking frame 231 is connected, and the limit switches 279 are provided at the first receiving members 277, respectively.
the control device 285 stops the driving of the rocking frame 231 in the rocking direction when an unnecessary external force is applied to the rocking frame 231 in the rocking state, one of the first receiving rollers 274 located on the lower side in the rocking direction of the rocking frame 231 floats from the first receiving member 277, and one of the limit switches 279 provided on the first receiving member 277 is turned off together with the other limit switch 279.
an alarm means such as lighting of a lamp or sounding a buzzer notifies an abnormal state.
the improvement in safety can be attempted.
the control device 285 prevents a floor plate body 232 from being driven by a back-raising drive source 237.
the control device 285 drives the rocking drive source 262 to prevent the floor plate body 232 from rocking.
the limit switch 279 is provided with the detection lever 281 located at the inner bottom of the arc-shaped recess portion 278 on which the first receiving roller 274 of the first receiving member 277 is supported.
the recess portion 278 is formed in an arc shape corresponding to the first receiving roller 274, and the first receiving roller 274 is thereby supported stably and reliably by the recess portion 278.
the first receiving roller 274 slightly floats from the recess portion 278, this matter is reliably detected by positioning the detection lever 281 of the limit switch 279 at the inner bottom of the recess portion 278.
the support state of the first receiving roller 274 in the recess portion 278 is accurately detected by the limit switch 279. For this reason, if an inadvertent external force is applied to the rocking frame 231 in the tilted state and the first receiving roller 274 on the lower end side of the rocking frame 231 in the rocking direction slightly floats from the recess portion 278, the limit switch 279 including the detection lever 281 in the recess portion 278 can detect this accurately and reliably. The control device 285 can thereby drive the bed device safely and reliably by the detection signal from the limit switch 279.
the rocking drive unit 229 engages the both ends of the lateral member 248 of the frame 250 with the receiving element 227 provided on the second frame part 209B of the vertical frame 209, and the connection shaft 287 is inserted into the through holes 248a and 227a provided in the end part of the lateral member 248 and the receiving element 227 and attached to the vertical frame 209.
connection shaft 287 is attached to one-side end of a flexible band member 288 formed of resin which is fixed to the middle part of the receiving element 227. For this reason, since the connection shaft 287 is prepared in advance at the connecting portion between the lateral member 248 and the receiving element 227, the attachment operation of the rocking drive unit 229 can be performed quickly.
connection shaft 287 removed from the connecting portion between the receiving element 227 and the frame 250 is held integrally with the receiving tool 227 by the band member 288, there is no risk of losing even if it is removed from the connecting portion.
the bed device including the vertical frame is described as an example in the above-described embodiments, but the bed device may not comprise the vertical frame. That is, in the above-described embodiment, the rocking drive unit is provided on the vertical frame as a bed frame but, in the case of a bed device comprising no vertical frame, the base frame may be used as a bed frame to attach the rocking drive unit.
the limit switch serving as the detector is provided on the first receiving member for receiving the first receiving roller, but both the first and second receiving members or only the second receiving member may be provided.
a third embodiment of the present invention will be described hereinafter with reference to FIG. 27 to FIG. 40 .
the third embodiment is different from the first embodiment with respect to a feature of further comprising a first receiving member provided integrally with a hinge.
the first receiving member allows the side floor plate to pivot upward from a horizontal state with respect to the central floor plate and prevents the side floor plates from pivoting downward from a horizontal state.

the vertical frame 303 is formed to have a rectangular frame shape in plan view by a pair of longitudinal rods 306 opposed in parallel and spaced apart at a predetermined interval, and a pair of board bodies 307 attached to one-side ends and the other ends of the longitudinal rods 306 in an upright position.
Bendable support members 308 for detachably attaching a side fence are provided and spaced apart with regular intervals in the longitudinal direction, on the outside surfaces of the pair of longitudinal rods 306 of the vertical frame 303.
a rocking frame 311 shaped in a rectangular frame shape (shown in FIG. 27 ) is arranged in the frame of the vertical frame 303. That is, the rocking frame 311 is set in a width dimension so as to enter the inside of the vertical frame 303. Then, the rocking frame 311 is driven to rock in the width direction by a rocking drive mechanism 312 (shown in FIG. 28 ) provided at one end of the vertical frame 303 in the longitudinal direction.
a floor plate body 315 is provided on the upper surface of the rocking frame 311. As shown in FIG. 27 or FIG. 30 , the floor plate body 315 is constituted by a blow-molded central floor plate 317 and a pair of side floor plates 318 having upper end portions in the thickness direction pivotally connected to both sides of the central floor plate 317 in the width direction by a flexible thin portion 316. When the floor plate body 315 is molded, the thin portion 316 is molded simultaneously.
the pair of side floor plates 318 are held in a lateral state with respect to the central floor plate 317 by the thin portion 316 and are pivotally connected only upward in the horizontal state with the connection portion of the thin portion 316 serving as a fulcrum and to be incapable of pivoting downward.
the central floor plate 317 and the pair of side floor plates 318 are divided into plural floor parts 317a to 317d and 318a to 318d each having a predetermined length.
the floor plates are divided into four parts, i.e., back floor parts 317a and 318a, two pairs of (two divisional) fixed floor parts 317b and 318b, first leg floor parts 317c and 318c, and second leg floor parts 317d and 318d.
a back floor part 317a is pivotally connected to one end in the longitudinal direction intersecting the width direction, and a first leg floor part 317c and a second leg floor part 317d are sequentially connected pivotally to the other end.
the width dimension of the central floor plate 317 is set to be substantially the same as the width dimension of the rocking frame 311.
the pair of side floor plates 318 protrude outward in the width direction of the rocking frame 311.
a back-raising drive unit 321 shown in FIG. 28 is provided on a lower surface side of the rocking frame 311.
the back-raising drive source provided at the back-raising drive unit 321 is activated, the back floor parts 317a and 318a of the central floor plate 317 and the side floor plates 318 can be made to pivot integrally in the raising direction as represented by chained lines in the drawing.
first leg floor parts 317c and 318c are pivotally driven in the raising direction while interlocked with the back floor part 317a and 318c or independently, and the second leg floor parts 317d and 318d are interlocked with this, such that both of the leg floor parts can raise the back floor parts in a substantially inverted V-shape.
the floor plate 315 can be made to rock in the width direction together with the rocking frame 311 as represented by a chain line in FIG. 29 .
the pair of side floor plates 318 provided on both sides of the central floor plate 317 can pivot in the only upward direction from a state of being horizontally maintained by the thin portion 316 with respect to the central floor plate 317 as explained above.
the side floor plate 318 located on the upper side in the pivoting direction of the floor plate body 315 is maintained in a horizontal state, and the side floor plate 318 located on the lower side contacts the upper surface of the longitudinal rod 306 of the vertical frame 303 and pivots and bends upward from a relatively horizontal state with respect to the central floor plate 317.
both end parts in the longitudinal direction, of both ends in the width direction of the back floor part 317a, the first leg floor part 317c, and the second leg floor part 317d of the central floor plate 317, and one-side ends in the width direction of the back floor parts 318a, the first leg floor parts 318c, and the second leg floor parts 318d of the pair of side floor plates 318, are pivotally connected by pairs of hinges 322, respectively, as described later.
the fixed floor part 317b of the central floor plate 317 and the fixed floor part 318b of the side floor plate 318 divided into two pieces are not connected by the hinges 322, but may be connected by the hinges 322.
the hinge 322 includes a first connection element 323 as shown in FIG. 33 to FIG. 35 .
the first connection element 323 has a rectangular plate shape in a plan view, and concave portions 324a opened on the upper surface and the side surface are formed at both ends in the width direction of one end of the first connection element 323. A pair of support portions 324 are thereby formed at one end of the first connection element 323.
First support holes 324b are formed in the pair of support portions 324 in the thickness direction, and a connection shaft 325 is inserted into the support holes 324b and supported so as not to be extractable.
One end part of a second connection element 326 having a rectangular plate in plan view is pivotally connected to the first connection element 323 by a connection shaft 325. That is, as shown in FIG. 33 , a protruding portion 327 is provided at the one end part of the second connection element 326, and a support hole 328 penetrating in the thickness direction is formed in the protruding portion 327.
the second connection element 326 is connected pivotally. Since the protruding portion 327 is located inside the recess portion 324a, the second connection element 326 is provided to pivot in the only upward direction with respect to the first connection element 323. That is, the connection element pivots in the only upward direction, similarly to the side floor plates 318 of the floor plate body 315.
a first receiving member 329 is molded integrally with the first connection element 323. That is, in the first receiving member 329, the substantially L-shaped side surface, and one end part is integrated with a lower surface part of a recess part 324a at which a pair of support portions 324 are formed, of the first connection element 323. The other end part of the first receiving member 329 is made to extend downward, bent toward the second connection element 323 side, and formed in the first engaging portion 331.
the hinges 322 attach and fix the first connection elements 323 to recessed first attachment portions 332 formed on both end parts in the longitudinal direction of upper surfaces of the back floor parts 317a, the first leg floor parts 317c, and the second leg floor parts 317d of the central floor plate 317, and attach and fix the second connection elements 326 to recessed second attachment portions 333 formed at both end parts in the longitudinal direction of upper surfaces of the back floor parts 318a, the first leg floor parts 318c, and the second leg floor parts 318d of the side floor plate 318.
FIG. 31 and FIG. 32 show the connected state of the back floor part 317a of the central floor plate 317 and the back floor part 318a of the side floor plate 318.
the first engagement member 331 of the first receiving member 329 provided at the first connection element 323 of the hinge 322 engages with a lower surface of the end part in the width direction of the side floor plate 318.
the first engagement portion 331 of the first receiving member 329 thereby prevents the side floor plate 318 in a horizontal state from pivoting downward.
FIG. 37 shows a state in which the side floor plate 318 pivots upward from a horizontal state and, in this case, the first engagement member 331 of the first receiving member 329 does not prevent the side floor plate 318 from pivoting upward.
the central floor plate 317 and the side floor plate 318 of the floor plate body 315 are pivotally connected by molding the thin portion 316 at the time of molding, but may be pivotally connected only by the hinge 322 without molding the thin portion 316.
a first recess portion 335 is formed on the lower surface of the back floor part 317a of the central floor plate 317, along the entire length in the width direction.
second recess portions 336 are formed at one-side ends in the width direction at positions corresponding to both ends of the first recess portion 335.
FIG. 32 shows the back floor parts 317a and 318a of the floor plate body 315 and, similarly, first and second recess portions 335 and 336 are formed on the first and second leg floor parts 317c, 318c, 317d, and 318d.
a second receiving member 337 such as a pipe member is detachably attached to the central floor plate 317 in the first recess portion 335.
the second receiving member 337 is set to have the length that allows both end parts in the longitudinal direction to project laterally from the first recess portion 335, and the both end parts engage with second recess portions 336 when the side floor plates 318 are in the horizontal state.
the second receiving member 337 thereby prevents the side floor plate 318 in a horizontal state from pivoting downward by its both ends together with the first receiving member 329. That is, when the side floor plates 318 are horizontal, both end parts of the second receiving member 337 serve as second engagement portions 338 that engage with the lower surfaces and support them.
the side floor plates 318 are pivotally connected to the central floor plate 317 only upward in the horizontal state by the hinges 322 and the thin portions 316.
the first engagement portion 331 of the first receiving member 329 provided integrally with the hinge 322 is engaged with the lower end surface in the width direction of the side floor plate 318.
the side floor plate 318 is thereby prevented from pivoting downward by the first engagement portion 331 and, even if a load W (shown in FIG. 37 ) is inadvertently applied to the upper surface of the side floor plate 318, the side floor plate 318 is prevented from pivoting downward with the load W.
a load W shown in FIG. 37
the side floor plate 318 is prevented from pivoting downward, it is possible to prevent the connection of the side floor plate 318 using the hinge 322 from being damaged and the thin portion 316 connecting the central floor plate 317 and the side floor plate 318 from being broken.
a second receiving member 337 is fixed to the central floor plate 317 in the first recess portion 335 and the second recess portion 336 formed on the lower surfaces of the central floor plate 317 and the side floor plate 318, and the lower surfaces of the pair of side floor plates 318 are supported by both ends of the second receiving member 337.
FIG. 39 shows a fourth embodiment of the present invention.
the fourth embodiment is different from the third embodiment with respect to a feature that the first receiving member 329 disclosed in the third embodiment is not provided at the hinge 322 which pivotally connects the central floor plate 317 and the side floor plates 318.
third receiving members 341 having a substantially L-shaped side surface are provided on both side surfaces in the width direction of the central floor plate 317.
one end part is provided integrally with the side surface of the central floor plate 317, and the other end part is extended downward and formed at a third engagement member 342 bent on the lower surface side of the side floor plates 318.
the third receiving member 341 may be formed integrally with the central floor plate 317 or may be formed separately from the central floor plate 317 and provided integrally with the central floor plate 317 with a screw, an adhesive, or the like.
FIG. 40 shows a fifth embodiment of the present invention.
the fifth embodiment is a modified example of the fourth embodiment, but is different from the fourth embodiment with respect to a feature that third receiving members 341 are provided on the side surfaces of the side floor plates 318 opposed to the side surfaces of the central floor plate 317.
the third receiving member 341 has one end part provided integrally with the side surface of the side floor plate 318 and, when the side floor plate 318 is in a horizontal state, a third engagement member 342 formed on the other end part engages with the lower surface of the end part in the width direction of the central floor plate 317.
the third receiving member 341 may be formed integrally with the side floor plate 318, similarly to the fourth embodiment, or may be integrally attached to the side surface of the side floor plate 318 as a separate body.
the bed device including the vertical frame is described as an example in the above-described embodiments, but the bed device may not comprise the vertical frame. That is, the vertical frame is exemplified as the bed frame provided with the rocking frame in the above-described embodiments but, in a bed device comprising no vertical frame, the base frame may be used as the bed frame and the rocking frame may be supported so as to rock at the bed frame.
the center floor plate and a pair of side floor plates are divided into several parts such as a back floor part and a leg floor part, as a floor board body, to enable the back raise and leg raise, has been explained as an example, but the central floor plate and the side floor plates may not be divided into a plurality of parts as he floor plate body.
