TECHNICAL FIELD
[0001] The present invention relates to a combination bed having a unit that can be separated
and used as a wheelchair.
Such a combination bed is for example known from JP 2001-314455 A, which corresponds to the preamble of claim 1.
BACKGROUND ART
[0002] When a caregiver transfers a care-receiver between a bed and a wheelchair, the caregiver
hurts his/her lower back in some cases. Here, the care-receiver refers to a bedridden
elderly person or a patient. In this point of view, a combination bed having a unit
separable and used as a wheelchair has been proposed (for example, see Japanese Unexamined
Utility Model Application Publication No.
H05-51330).
[0003] FIG. 9 is a perspective view illustrating conventional combination bed 1 (hereinafter,
referred to as bed 1). In bed 1, a surface on which a user lies is formed of lateral
base boards 2 and 4 of bed unit 1A, and middle base board 3 of wheelchair unit 5.
This surface is formed by moving flattened middle base board 3 to space 3A between
lateral base boards 2 and 4. Bed 1 is configured such that arm 8 is rotated about
rotary device 7 in a direction indicated by arrow 7A so as to lift lateral base board
4 fixed to arm 8, thus allowing wheelchair unit 5 to be moved to space 3A. As described
above, bed 1 allows easy transfer of a care-receiver (an occupant of wheelchair unit
5) between wheelchair unit 5 and bed unit 1A.
[0004] A pair of railings 9 of wheelchair unit 5 are used as armrests of the wheelchair.
When wheelchair unit 5 is coupled to bed unit 1A, railings 9 are pulled out from insertion
holes 9B of wheelchair unit 5 and inserted into insertion holes 9A of bed 1, thereby
serving as side rails of bed 1.
[0005] Such bed 1 can reduce a caregiver's burden of transferring a care-receiver between
wheelchair unit 5 and bed 1.
SUMMARY OF THE INVENTION
[0006] The invention is defined by the appended independent claim.
[0007] It is an object of the present invention to provide a combination bed having a reduced
risk that a care-receiver may fall off and achieving a high level of safety.
[0008] A combination bed according to the present invention includes a bed unit, and a wheelchair
unit separable from the bed unit. The bed unit includes a first main body part,; a
first seating surface part attached to the first main body part, and a U-shaped member
located below the first seating surface part and fixed to the first main body part.
The wheelchair unit includes a second main body part, a second seating surface part,
a first armrest, and a second armrest. The second main body part has a first lateral
surface and a second lateral surface opposite the first lateral surface. The first
lateral surface faces the bed unit when the bed unit and the wheelchair unit are being
combined. The second seating surface part is attached to the second main body part.
The first armrest is vertically slidable and attached to the first lateral surface
of the second main body part. The second armrest is vertically slidable and attached
to the second lateral surface of the second main body part. When the bed unit and
the wheelchair unit are being combined and the first armrest is lowered, the U-shaped
member is capable of receiving a portion of the first armrest.
[0009] With the above configuration, the combination bed according to the present invention
has a reduced risk that a care-receiver may fall off, and achieves a high level of
safety.

DESCRIPTION OF EMBODIMENT
[0011] Prior to an embodiment of the present invention, a problem in conventional bed 1
illustrated in FIG. 9 will be described briefly. In bed 1, wheelchair unit 5 can be
separated even when railings 9 are not attached to wheelchair unit 5. Thus, at the
time of separating wheelchair unit 5, there is a risk that a care-receiver may roll
in a direction across his/her shoulders and fall off.
[0012] Hereinafter, an embodiment of the present invention is described with reference to
the accompanying drawings. Same structural components are assigned same reference
signs, and description of such structural components may be omitted. Also, in order
to facilitate understanding of the drawings, major structural components are each
illustrated schematically.
[0013] FIG. 1A to FIG. 1C are drawings for describing combination bed 100 (hereinafter,
referred to as bed 100) according to an embodiment of the present invention. FIG.
1A is a perspective view illustrating a combined state. FIG. 1B is a perspective view
illustrating a state in which wheelchair unit 10 is locked by an interlocking mechanism.
FIG. 1C is a perspective view illustrating a separation state in which wheelchair
unit 10 is separated. FIG. 1D is a perspective view illustrating a state in which
first armrest 14 is lifted.
[0014] As illustrated in FIG. 1A to FIG. 1C, bed 100 includes wheelchair unit 10 and bed
unit 20.
[0015] Bed unit 20 includes base frame 21 with castors, lifting and lowering part 22 attached
to base frame 21, upper frame 23, first seating surface part 24, first fixing part
25, and U-shaped pipe 211. Height of first seating surface part 24 and height of upper
frame 23 can be varied by lifting and lowering part 22. A first main body part of
bed unit 20 is constituted by base frame 21, lifting and lowering part 22, upper frame
23 and first fixing part 25.
[0016] The first main body part is an example of a bed main body part. First seating surface
part 24 is an example of a bed seating surface part, and combined with second seating
surface part 12 of wheelchair unit 10 so as to form a surface of bed 100. First fixing
part 25 is an example of a wheelchair fixing part for removably attaching wheelchair
unit 10.
[0017] First seating surface part 24 is attached to upper frame 23. The first seating surface
part 24 can be changed its posture. First fixing part 25 is fixed to upper frame 23
and provided for removably attaching wheelchair unit 10. U-shaped pipe 211, which
is an example of a U-shaped member, is fixed to base frame 21. In other words, bed
unit 20 includes the first main body part, first seating surface part 24 attached
to this first main body part, and the U-shaped member that is located below first
seating surface part 24 and fixed to the first main body part.
[0018] Wheelchair unit 10 includes second main body part 11 with castors, second seating
surface part 12, first armrest 14, and second armrest 13. Second seating surface part
12 is attached to second main body part 11. The second seating surface part 12 can
be changed its posture. Second main body part 11 is an example of a wheelchair main
body part. Second seating surface part 12 is an example of a wheelchair seat part.
First armrest 14 and second armrest 13 are attached to second main body part 11. First
armrest 14 and second armrest 13 are an example of armrests.
[0019] Second main body part 11 has a first lateral surface that faces bed unit 20 when
bed unit 20 and wheelchair unit 10 are being combined, and a second lateral surface
opposite the first lateral surface. First armrest 14 is attached to the first lateral
surface, and second armrest 13 is attached to the second lateral surface. In the example
illustrated in FIG. 1C, the first lateral surface is on a left-hand side of care-receiver
200, and the second lateral surface is on a right-hand side of care-receiver 200.
[0020] Although detailed mechanisms will be described later, second armrest 13 and first
armrest 14 are vertically slidable. By vertically sliding second armrest 13 and first
armrest 14, it is possible to place them in a lifted state and a lowered state. In
FIG. 1A, second armrest 13 is in the lifted state, and first armrest 14 is in the
lowered state.
[0021] Now, a separation method of bed 100 will be described with reference to FIG. 1A to
FIG. 1D and FIG. 2. FIG. 2 is a flowchart illustrating a method for separating wheelchair
unit 10.
[0022] In a state where wheelchair unit 10 and bed unit 20 are combined, a caregiver first
moves care-receiver 200 onto wheelchair unit 10 as illustrated in FIG. 1A (Step S01
in FIG. 2).
[0023] Subsequently, the caregiver operates lifting and lowering part 22 so as to lower
upper frame 23 until second main body part 11 touches a floor. After second main body
part 11 touches the floor, only bed unit 20 is lowered further, so that wheelchair
unit 10 is disengaged from first fixing part 25 (Step S02 in FIG. 2). This makes it
possible to move wheelchair unit 10 away from bed unit 20. At this time, a step is
formed between second seating surface part 12 and first seating surface part 24 such
that the former is higher than the latter.
[0024] Then, the caregiver pulls out wheelchair unit 10 to a first separation position illustrated
in FIG. 1B (Step S03 in FIG. 2). At this time, in bed 100, a portion (a lower end
portion) of first armrest 14 is located within and in contact with U-shaped pipe 211
fixed to base frame 21. Thus, in the first separation position, wheelchair unit 10
cannot be pulled out any further. Here, the state where the portion of first armrest
14 is located within U-shaped pipe 211 is a state indicated by dashed lines in FIG.
1D and illustrated in FIG. 8A and FIG. 8B described later. In this manner, wheelchair
unit 10 is disengaged from first fixing part 25 in a state where bed unit 20 is lowered
by lifting and lowering part 22. In the state where wheelchair unit 10 is disengaged
from first fixing part 25 and first armrest 14 is located within U-shaped pipe 211,
wheelchair unit 10 can move only between a position in contact with bed unit 20 and
a first separation position.
[0025] In this state, as illustrated in FIG. 1D, the caregiver lifts first armrest top 141A
serving as an elbow rest of first armrest 14 to a position above second seating surface
part 12. This locates first armrest 14 outside U-shaped pipe 211, making it possible
to pull out wheelchair unit 10 because first armrest 14 is not in contact with U-shaped
pipe 211 (Step S04 in FIG. 2). Here, the state where first armrest 14 is located outside
U-shaped pipe 211 is a state indicated by solid lines in FIG. 1D and illustrated in
FIG. 8C and FIG. 8D described later
[0026] In this manner, when the caregiver pulls out wheelchair unit 10 with first armrest
14 lifted up, he/she can pull it out to a second separation position as illustrated
in FIG. 1C (Step S05 in FIG. 2).
[0027] The first separation position is a position of wheelchair unit 10 at which a gap
sufficient for lifting up first armrest 14 can be formed between wheelchair unit 10
and bed unit 20. In other words, the first separation position is a position when
wheelchair unit 10 is slightly pulled out from the combined state. Also, the second
separation position is a position of wheelchair unit 10 at which wheelchair unit 10
and bed unit 20 are completely separated.
[0028] Unless first armrest top 141A of first armrest 14 is lifted to the position above
second seating surface part 12, wheelchair unit 10 cannot be pulled out and separated
from bed 100. In other words, in order to separate wheelchair unit 10 from bed 100,
it is necessary to lift first armrest 14 and cause it to function as a railing. In
this way, bed 100 has a safe separation mechanism for care-receiver 200.
[0029] Although a configuration of separating wheelchair unit 10 toward the right-hand side
of care-receiver 200 has been described in the present embodiment, a configuration
of separating it toward the left-hand side of care-receiver 200 is also possible.
In that case, not first armrest 14 but second armrest 13 makes contact with U-shaped
pipe 211. In the description, first armrest 14 is to be replaced by second armrest
13.
[0030] FIG. 3A is a perspective view illustrating wheelchair unit 10 in a flattened state,
and FIG. 3B is a perspective view illustrating wheelchair unit 10 in a chair state.
The flattened state refers to a state in which second seating surface part 12 of wheelchair
unit 10 is flat. The chair state refers to a state in which, as illustrated in FIG.
3B, second seating surface part 12 of wheelchair unit 10 is shaped as a chair having
a back rest, a seat, a foot rest and so on. After wheelchair unit 10 is separated
from bed unit 20, second seating surface part 12 can be changed its posture. In other
words, the posture of second seating surface part 12 can be changed from the flattened
state in FIG. 3A to the chair state in FIG. 3B. Wheelchair unit 10 in the chair state
in FIG. 3B can be used as a wheelchair.
[0031] Next, movement of first armrest 14 will be described with reference to FIG. 4A to
FIG. 7. FIG. 4A is a perspective view illustrating a lifted state of first armrest
14, and FIG. 4B is a perspective view illustrating the lowered state of first armrest
14. FIG. 5 to FIG. 7 are perspective views respectively illustrating first component
141, second component 142 and third component 143 of first armrest 14.
[0032] As illustrated in FIG. 4A and FIG. 4B, first armrest 14 includes third component
143 that is attached to second main body part 11 at a second fixing part with a screw
or the like, second component 142 slidable inside third component 143, and first component
141 slidable inside second component 142.
[0033] As illustrated in FIG. 5, first component 141 includes first armrest top 141A, first
pipe 141B, first pin 141C, and lever 141D. First armrest top 141A is a member on which
an arm of care-receiver 200 is placed. First pipe 141B supports first armrest top
141A and also slides inside second component 142. First pin 141C is provided in a
lower portion of first pipe 141B. In other words, first pipe 141B is attached to first
armrest top 141A and first pin 141C is provided to first pipe 141B at an opposite
side to first armrest top 141A along an extending direction of first pipe 141B.
[0034] Lever 141D is provided for operating first pin 141C. Although not illustrated in
FIG. 5, first component 141 includes a mechanism that allows first pin 141C to be
retracted in first pipe 141B when lever 141D is lifted. In other words, first pin
141C is provided in such a manner as to protrude from a lateral surface of first pipe
141B and be retracted in first pipe 141B.
[0035] As illustrated in FIG. 6, second component 142 includes second pipe 142A and second
pin 142B. Furthermore, a plurality of first holes 142C are provided in a lateral surface
of second pipe 142A. First pin 141C can be fitted into each of first holes 142C. First
pin 141C is fitted into one of first holes 142C, whereby a position of first component
141 is attached with respect to second component 142. Although not illustrated in
FIG. 6, a lower portion of second pipe 142A is provided with a mechanism that allows
second pin 142B to be retracted in second pipe 142A when first component 141 slides
to a lower position. That is to say, second pipe 142A can store first pipe 141B therein,
and has first holes 142C into which first pin 141C is fitted and second pin 142B.
The second pin 142B. At an opposite side to first holes 142C along an extending direction
of second pipe 142A, second pin 142B is provided in such a manner as to protrude from
the lateral surface of second pipe 142A and be retracted in second pipe 142A.
[0036] As illustrated in FIG. 7, third component 143 includes third pipe 143A, and second
fixing part 143C that fixes third pipe 143A to second main body part 11 with a screw
or the like. Second hole 143B is provided in a lateral surface of third pipe 143A.
Second pin 142B is fitted into second hole 143B, whereby second component 142 is attached
to third component 143. That is to say, third pipe 143A can store second pipe 142A
therein, and is provided with second hole 143B into which second pin 142B is fitted.
[0037] Now, movement for turning the lifted state in FIG. 4A to the lowered state in FIG.
4B will be described. First, the caregiver grips lever 141D to operate first pin 141C
and pull it out from first hole 142C. By this operation, first component 141 is disengaged
from second component 142. As a result, first component 141 becomes freely slidable
with respect to second component 142. When the caregiver pulls down first component
141 in this state, second pin 142B is operated and pulled out from second hole 143B.
By this operation, second component 142 is disengaged from third component 143. As
a result, second component 142 becomes freely slidable with respect to third component
143. When the caregiver pulls down first component 141 in this state, second component
142 is stored in third component 143, thus achieving the lowered state illustrated
in FIG. 4B.
[0038] A lifting operation in Step S04 in FIG. 2 is the reverse of the pulling down operation
described above. First, the caregiver grips lever 141D to operate first pin 141C and
disengage first component 141. In this state, the caregiver lifts up freely-operable
first component 141. This allows first pin 141C to be fitted into one of first holes
142C, so that first component 141 is attached to second component 142. When the caregiver
lifts first component 141 in this state, second pin 142B is fitted into second hole
143B, so that second component 142 is attached to third component 143.
[0039] FIG. 8A to FIG. 8D are drawings for describing a positional relationship between
first armrest 14 and U-shaped pipe 211 during separation. FIG. 8A and FIG. 8B are
partially enlarged views respectively illustrating a state in which bed unit 20 is
at a low end and a state in which first armrest 14 is in contact with U-shaped pipe
211. Also, FIG. 8C and FIG. 8D are partially enlarged views respectively illustrating
a state in which first armrest 14 is lifted and a state in which wheelchair unit 10
is released outwardly from the first separation position.
[0040] As described earlier, in order to separate wheelchair unit 10 from bed unit 20, bed
unit 20 is lowered first by lifting and lowering part 22 to a position illustrated
in FIG. 8A. When wheelchair unit 10 is pulled out in this state, second component
142 makes contact with U-shaped pipe 211 as illustrated in FIG. 8B. At this time,
a gap of about 90 mm is present between wheelchair unit 10 and bed unit 20. This gap
is narrow enough to prevent care-receiver 200 from falling off. However, owing to
this gap, a gap of about 40 mm is secured beside first armrest top 141A having a width
of about 50 mm, thus allowing insertion of a human hand. As described above, a position
at which this gap is formed corresponds to the first separation position. In other
words, the first separation position is away from bed unit 20 by the width of first
armrest 14 plus 40 mm. Also, the first separation position is away from bed unit 20
by 90 mm, for example, as described above.
[0041] When first component 141 is lifted in this state to a position illustrated in FIG.
8C, second component 142 moves out of contact with U-shaped pipe 211. This makes it
possible to separate wheelchair unit 10 from bed unit 20 as illustrated in FIG. 8D.
[0042] In the above description, for achieving a small overall height in the lowered state,
first armrest 14 is constituted by first component 141, second component 142 and third
component 143. Additionally, second pipe 142A is provided with the plurality of first
holes 142C so that a height of first armrest top 141A can be adjusted in the lifted
state.
[0043] However, there are some cases where first armrest 14 may also be slightly high even
in the lowered state because the surface of bed 100 is high and the height of first
armrest top 141A need not be adjusted. In such cases, first armrest 14 may be constituted
only by first component 141 and third component 143. In this case, an inner dimension
of third pipe 143A and an outer dimension of first pipe 141B are adjusted so that
first pipe 141B can slide inside third pipe 143A. In this case, first pin 141C functions
as a locking mechanism that is fitted into second hole 143B and disengageably attaches
first pipe 141B to third pipe 143A.
[0044] With the configuration described above, bed 100 can achieve a combination bed that
can be separated and used as a wheelchair, has a reduced risk that care-receiver 200
may fall off, and achieves a high level of safety.
[0045] A portion of bed 100 is separated for use as a wheelchair, so that bed 100 is useful
as a wheelchair/bed for nursing a bedridden elderly person or a patient.
